Further, the directional terms referred to in the following embodiments, such as up, down, left, right, etc., only indicate the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not intended to limit the scope of the present disclosure.

[0027] The present disclosure will be further described below with reference to the accompanying drawings and preferred embodiments.

[0028] According to an embodiment of the present disclosure, there is provided a fertilization cart. With reference to FIGS. 1 to 5, the fertilization cart includes a hopper 1 for containing the fertilizer, a first turntable 5, and a second turntable 6, where the first turntable 5 and the second turntable 6 are located below the hopper 1 and arranged in correspondence with discharge openings 11 on the hopper 1. Spreader openings 55 are formed on either of the first turntable 5 and the second turntable 6, and when the spreader openings 55 are communicated with the discharge openings 11 after rotating, a spreader channel is formed. The first turntable 5 is capable of rotating relative to the hopper 1 to open or close the spreader channel. The second turntable 6 is capable of rotating relative to the first turntable 5 to adjust the size of the spreader channel. A throwing disc 7 is arranged below the second turntable 6, and the throwing disc 7 rotates to radially spread the fertilizer falling into the throwing disc 7.

[0029] It should be noted that, when the fertilization cart works, the second turntable 6 is first rotated to adjust the position of the spreader opening 55 on the second turntable 6, and then the spreader opening 55 of the first turntable 5 is rotated to align with the discharge opening 11 of the hopper 1, so that the spreader channel is opened, and the fertilizer falls into the throwing disc 7 and is spread as the throwing disc 7 rotates. The opening/closing state and size of the spreader channel are controlled by the first turntable 5 and the second turntable 6 respectively. To use another type of fertilizer, it is only necessary to close the spreader channel and adjust the rotation angle of the second turntable 6, without need of replacing the fertilization cart, which is capable of accurately controlling the amount of fertilizer for different vegetation, with high work efficiency despite of simple operation steps.

[0030] Specifically, the first turntable 5 is located below the hopper 1 and fitted with the discharge opening 11 of the hopper 1, while the second turntable 6 is located below the first turntable 5 and fitted with the first turntable 5.

[0031] Preferably, the first turntable 5 and the second turntable 6 are both of a semicircular structure or a fan-shaped structure with a central angle greater than 180 degrees.

[0032] The fertilization cart of this embodiment further includes a rack 2, the hopper 1 is mounted on the rack 2, a control handle 21 is arranged on the rack 2, and the control handle 21 is connected to the first turntable 5. The first turntable 5 is rotated by controlling the control handle 21, so that the spreader channel is opened or closed. Preferably, a lug 54 is arranged at the edge of the first turntable 5, a spring is connected to the lug 54, the control handle 21 and the first turntable 5 are connected through the spring, and the spring is adjusted by means of the control handle 21 to control the first turntable 5.

[0033] Rollers 3 are connected to the bottom of the rack 2, a transmission assembly 4 is fixedly arranged on the axle of the roller 3, and the transmission assembly 4 is in transmission connection with the throwing disc 7.

[0034] It should be noted that, the transmission assembly 4 includes a gear disc 41 and a rotating shaft 42, where the gear disc 41 is provided with a first bevel gear and a second bevel gear that are meshed with each other. The first bevel gear rotates with the rollers 3, the rotating shaft 42 is fixedly connected to the center of the second bevel gear, and the throwing disc 7 is fixedly connected to the second bevel gear through the rotating shaft 42, so that the throwing disc 7 rotates with the second bevel gear, thereby spreading the fertilizer.

[0035] Specifically, the first turntable 5, the second turntable 6 and the throwing disc 7 are coaxially arranged, and the rotating shaft 42 sequentially penetrates through the centers of throwing disc 7, the second turntable 6 and the first turntable 5, and also the bottom of the hopper 1, and is limited by a positioning pin to ensure the stability of the fertilization cart.

[0036] In the fertilization cart of this embodiment, the discharge opening 11 and the spreader opening 55 have the same shape, and a plurality of discharge openings 11 and spreader openings 55 are arranged at intervals along the circumferential direction, to ensure uniform fertilizer spreading. Further, the arrangement at intervals ensures that the spreader channel can be closed by rotating the first turntable 5.

[0037] In the fertilization cart of this embodiment, a first limiting block 51 is fixedly arranged at the bottom of the first turntable 5, arc-shaped first limiting holes 61 are formed on the second turntable 6, the first limiting block 51 is slidably embedded into the first limiting hole 61, and the rotation range of the first turntable 5 is limited through matching of the first limiting block 51 and the first limiting hole 61.

[0038] In the fertilization cart of this embodiment, a plurality of arc-shaped second limiting holes 52 are formed on both the first turntable 5 and the second turntable 6 along the circumferential direction, and a second limiting block 53 penetrates through the second limiting hole 52 and is detachably connected to the hopper 1. Two end portions of the second limiting hole 52 are equidistant from the center of the first turntable 5, and the two end portions of the second limiting hole 52 are also equidistant from the center of the second turntable 6.

[0039] The fertilization cart of this embodiment further includes an adjusting assembly 8, and the adjusting assembly 8 includes a first connecting plate 81 that is fixedly connected to the hopper 1 and a baffle plate 82 that is located on an inner side of the first connecting plate 81 and detachably connected to the first connecting plate 81. The inner side thereof is closer to the first turntable 5, and the bottom of the baffle plate 82 is not lower than the throwing disc 7.

[0040] Specifically, the baffle plate 82 is arranged near the throwing disc 7 and located behind the throwing disc 7. Due to the arrangement of the baffle plate 82, the fertilizer cannot fall backward during fertilization, thereby preventing skin exposure of the operator to the fertilizer, and avoiding harm to the human body.

[0041] In the fertilization cart of this embodiment, a limiting plate 83 is fixedly arranged on the inner side of the first connecting plate 81, and a plurality of grooves are formed on the limiting plate 83. A second connecting plate 62 is extended radially along the second turntable 6, a third limiting block 63 is fixedly arranged on the second connecting plate 62, a plurality of protrusions 64 that are in fit with the grooves 84 are arranged on the third limiting block 63, and the number of the protrusions 64 is less than the number of the grooves 84.

[0042] It should be noted that, through the adjustment of relative positions of the second connecting plate 62 and the limiting plate 83, the protrusions 64 can be embedded into different grooves 84, so that the size of the spreader channel can be adjusted by switching different gear positions. Due to the matching of the protrusions 64 and the grooves 84, the second turntable 6 can be fixed, so that the uniformity of fertilizer spreading during rotation of the second turntable 6 when the fertilization cart works is ensured. Specifically, 17 gear positions are arranged, to adapt to the circumstances of spreading different fertilizers. Further, a plectrum 65 and a pointer 66 are arranged at an end portion of the second connecting plate 62, where the pointer 66 is in fit with an outer wall of the first connecting plate 81, the outer wall of the first connecting plate 81 is provided with scales indicating gear positions, and the pointer 66 points to the scale to facilitate the intuitive and accurate adjustment of the size of the spreader channel. By pressing down the plectrum 65, the protrusion 64 can be pulled out of the groove 84, so that the gear position is changed.

[0043] When the fertilization cart is idle, the spreader channel is closed. After loading the fertilizer into the hopper 1, the plectrum 65 is moved according to the type of fertilizer and the required spreading density to adjust the gear position, until the size of the spreader channel is appropriate. In this case, the fertilizer operator behind the fertilization cart controls the control handle 21 to open the spreader channel, and pushes the fertilization cart forward. The fertilizer falls into the throwing disc 7 through the spreader channel and is spread as the throwing disc 7 rotates. After the fertilization is completed, the control handle 21 is controlled again to close the spreader channel.

[0044] The present disclosure has been described above in detail. The above embodiments are merely preferred embodiments of the present disclosure, and are not intended to limit the scope of implementations of the present disclosure, that is, equivalent changes and modifications made within the scope of claims of the present disclosure shall fall within the scope of the present disclosure.
