Seed dispensing device and system

Abstract

The dispensing device and system pivotally attach to a hopper bottom trailer to deliver seed from the trailer to planters located throughout the farm. A main conduit inserts into a housing installed at the hopper of the trailer. A gate opens that allows seed to flow through the hopper into the housing. A main conduit inserts into the housing to collect seed and lift the seed both vertically and horizontally. An auger directs the seed upwards through the main conduit towards the dispensing conduit. The seed then gravitationally feeds downward from the dispensing conduit. A flexible conduit enables the user to direct the seed to different planters without moving the trailer.

DETAILED DESCRIPTION

(12) FIG. 1 shows the dispensing device 100 secured to trailer 101. The dispensing device 100 is placed in transport mode as shown in FIG. 1 when travelling. The dispensing device 100 secures against the trailer while the trailer 101 is in motion.

(13) Support arm 118 pivotally attaches to trailer 101 at support attachments 120, 121. Support attachments 120, 121 allow pivoting of support arm 118 away from trailer 101 for use. Support arm 118 pivots away from trailer 101 to position the main conduit 102 into the housing 124.

(14) In one embodiment, tether 156 secures the support arm 118 against the trailer 101 while the auger is in use. Tether 156 limits movement of the main conduit 102 to retain the auger 122 within housing 124 during operation of the auger. The user releases tether 156 from the trailer 101 to reposition the support arm 118 for travel.

(15) The main conduit pivots at pivots 112, 114, 116. Support brace 110 increases the rigidity of conduit 102 to prevent flexing of the conduit while in use. Support brace 110 provides an attachment point for securing conduit 102 to pivot 112. Auger 122 extends through main conduit 102. The auger 122 draws seed into the main conduit 102 at auger 122 to deliver the seed via dispensing conduit 108. Flexible conduit 106 enables the user to move dispensing conduit 108. The flexibility of conduit 106 allows the user to deliver seed to multiple planters without moving the trailer 101.

(16) The dispensing device 100 is secured in the transport mode as shown in FIG. 1. Latch 103 secures the main conduit 102 and the support 110 to the trailer 101. Latch 103 limits movement of the main conduit and prevents the main conduit from moving away from the trailer 101 into the use mode.

(17) Tether 109 secures dispensing conduit 108 to trailer 101. The tether attaches to trailer 101 and passes over dispensing conduit 108 and through grip 132. Securing dispensing conduit 108 to the trailer 101 prevents damage to other property and the dispensing device 100.

(18) The dispensing device 100 also provides an adjustment arm 111 that assists with adjusting the main conduit 102 between use mode and transport mode. Latch 103 is located high enough on the trailer such that some users need assistance placing the main conduit 102 within latch 103 for securing the main conduit 102 into transport mode. Adjustment arm 111 is constructed from a rigid material, such as metal, to assist the user when lifting the main conduit 102 upwards into latch 103. Adjustment arm 111 of one embodiment attaches to support 110 to assist with positioning main conduit 102.

(19) In transport mode, the first end 99 of the main conduit 102 is secured adjacent the trailer 101. To dispense seed from the trailer, the user first secures the housing 124 at hopper 130 of trailer 101. The user inserts the first end 99 of the main conduit 102 into insertion aperture 126 of housing 124 to dispense the seed through the dispensing device 100. To insert the first end 99 into insertion aperture 126, the user first releases the latch 103 and tethers 109 to reposition the main conduit 102 and support arm 118.

(20) The user then pivots the support arm 118 outward away from trailer 101. Pivot 116 allows the user to rotate pivot arm 115 around a first axis, such as a vertical axis. Pivot arm 115 positions pivots 112, 114 radially outward from pivot 116. Handle 152 provides the user with a grip to position pivot arm 115. The handle 152 assists the user with inserting the auger 122 into housing 124. In one embodiment, the handle 152 is secured to the vertical support 113.

(21) Pivot 114 enables rotation of vertical support 113. Rotation of vertical support 113 via pivot 114 allows rotation of main conduit 102 around the vertical axis. Conduit 102 pivots on a second axis, such as a lateral axis, at pivot 112. Pivot 112 adjusts the height of first end 99 and auger 122. The user adjusts the height of first end 99 and auger 122 for insertion of the auger 122 into insertion aperture 126. The user inserts first end 99 of the main conduit 102 into insertion aperture 126 of the guide conduit. The tether 156 of one embodiment secures support 110 to the trailer 101 during operation of the auger 122. The user can then start the actuator 104 and auger 122 to transfer the seed from trailer 101 and housing 124 into the planter. The seed travels from first end 99 to the dispensing conduit 108. Auger 122 directs the seed from the first end 99 to the dispensing conduit 108.

(22) At least a portion of auger 122 is exposed outside of the first end 99 of main conduit 102. The first end 99 inserts into insertion aperture 126. The exposure of auger 122 outside of main conduit 102 increases contact of auger with the seed. The user inserts auger 122 into the housing 124 at insertion aperture 126. The auger 122 inserted into housing 124 at hopper 130 contacts the seed within housing 124. The auger 122 transports the seed up the main conduit 102 towards actuator 104 and dispensing conduit 108. The seed reaches the dispensing conduit 108 that gravitationally feeds the seed through the dispensing conduit 108 and delivers the seed to the planter.

(23) FIGS. 1 and 2 show housing 124 secured to the bottom of the trailer 101. The attachment arms of the housing contact an attachment body 128 extending vertically below the trailer 101. The attachment body 128 secures the housing 124 to the trailer 101 for transportation. The attachment body 128 secures the housing 124 to the trailer 101 with sufficient clearance above the ground to allow movement of the trailer 101 without damaging housing 124.

(24) Hopper 130 of the trailer 101 allows seed to flow through the trailer 101. The seed flows from trailer 101 through a trailer aperture within the trailer located at hopper 130. A gate located at the hopper 130 controls the flow of the seed from the hopper 130. The gate closes to prevent seed from flowing through hopper 130. To enable the seed to be delivered, the gate is opened to allow the seed through hopper 130.

(25) FIG. 2 shows the main conduit 102 released from transport mode. Auger 122 inserts into insertion aperture 126 to be used. Because auger 122 inserts downward into housing 124, weight 123 biases the auger 122 downwards towards housing 124. Weight 123 counters the weight of the actuator, main conduit, flexible conduit, and dispensing conduit at pivot 112.

(26) The housing 124 secures to the trailer 101 at hopper 130 as shown in FIG. 3. The user inserts auger 122 into housing 124 at insertion aperture 126. The user opens gate at hopper 130 to allow seed to flow into housing 124 from trailer 101. The auger 122 driven by actuator 104 draws the seed into main conduit 102. The seed then flows through flexible conduit 106 and dispensing conduit 108 for delivery of the seed into the planters. FIG. 3 also shows the lines 131 to actuator 104 that activate the actuator 104. The actuator 104 can be driven by hydraulics, electricity, pneumatics, etc. In one embodiment, a relief valve 154 connects the lines 131 to prevent damaging the auger 122 and actuator 104 due to increased pressure of the fluid, such as oil or other liquid. The relief valve 154 enables the hydraulic pressure to bypass actuator 104 to reduce movement of auger 122.

(27) FIG. 4 shows the housing 124 secured to the attachment body via trailer arms 134, 135. Trailer arms 134, 135 support attachment arms 136, 138 of the housing 124. In one embodiment, the housing 124 secures to the attachment body and trailer 101. A pin or other fastener inserts into an aperture 137, shown in FIG. 8, that passes through both the housing 124 and the trailer 101 to secure the housing 124 to trailer 101. In another embodiment, the pin or other fastener inserts into an aperture that passes through both the attachment arm 136, 138 and the trailer arm 134, 135. The pin or other fastener limits movement of the housing 124 when in transport mode to secure the housing 124 to the trailer 101.

(28) FIGS. 5-8 show different views of the housing 124. Upper aperture 125 of housing 124 allows seed to flow downward from trailer 101 into housing 124. The seed flows from the trailer 101 through hopper 130 into housing 124.

(29) Attachment arms 136, 138 extend laterally outward from the side walls 142, 144. The attachment arms 136, 138 support the housing 124 when the housing 124 is secured to the trailer 101 at either hopper 130 or on the attachment body via trailer arms 134, 135. Fastener aperture 137 of housing 124 accepts the fastener or pin to secure the housing 124 to trailer 101 as described above.

(30) Side walls 142, 144 and rear wall 146 direct the seed towards front wall 140, insertion aperture 126, and guide conduit 127. The seed flows from the trailer 101 into housing 124. The auger 122 inserts into insertion aperture 126. Guide conduit 127 directs auger 122 to the bottom of housing 124. Side walls 142, 144 and rear wall 146 direct the seed towards the auger 122. Because seed is directed towards guide conduit 127, insertion aperture 126 and front wall 140, the front wall 140 is shaped to direct the seed down towards insertion aperture 126 and guide conduit 127. Wings 143, 145 angle inwards and down toward guide conduit 127.

(31) FIGS. 9 and 10 show the housing 124 installed onto trailer 101 at hopper 130. A gate of hopper 130 opens and closes to control the flow of seed from trailer 101 through hopper 130 into housing 124. Hopper arms 148, 150 support attachment arms 136, 138 of housing 124 to secure the housing 124 to trailer 101 at hopper 130.

(32) In one embodiment, support 110 attaches to the trailer after the auger 122 inserts into housing 124 via insertion aperture 126. The user may tether or otherwise secure support 110 to the trailer 101 while the auger 122 is inserted into housing 124. The attachment of the support 110 to the trailer 101 via tether 156 secures both the main conduit 102 and the housing 124 into use mode. In another embodiment, a fastener or pin inserts into aperture 137 of housing 124 and trailer 101 at hopper 130 to secure the housing in use mode. In use mode, the auger 122 transfers the seed from the housing 124 through dispensing conduit 108 to the planters.
