DESCRIPTION

(7) As seen in FIGS. 1-5, the present invention describes a support gate device 100 that allows iron tubes to be loaded efficiently into a holding bin 90 of a directional drilling machine. The support gate device 100 comprises of a rectangular cartridge 10 that has a top side 10a, a bottom side 10b, a left side 10c and a right side 10d, the top side 10a and the bottom side 10b are parallel to each other and the left side 10c and the right side 10d are parallel to each other, the rectangular cartridge 10 defines an empty space 10e between the left side 10c and the right side 10d, both the left side 10c and the right side 10d of the rectangular cartridge 10 define a lower through hole 12 and an upper through hole 14, the lower though holes 12 are parallel to each other and the upper through holes 14 are parallel to each other, and the top side 10a of the rectangular cartridge defines 10 a rear through hole 16. A gate 20 that has a front side 20a, a rear side 20b, a left side 20c, a right side 20d, a top side 20e and a hinge side 20f, the hinge side 20f is v-shaped, the front side 20a is curved shaped, the top side 20e is linear and the rears side 20b is linear, the left side 20c and right side 20d are a set of planes that are parallel to each other and they define a hinge through hole 22 that is adjacent to an apex 20g of the hinge side 20f of the gate 20 and the left side 20c and the right side 20d of the gate 20 also define a pin through hole 24 that runs at a perpendicular position from the top side 20e of the gate 20 and that is linearly aligned between the top side 20e of the gate 20 and the hinge through hole 22, a stop plate 26 is attached to the rear side 20b of the gate 20 and the stop plate 26 defines a spring through hole 28 that is at a position that is aligned with the top side 20e of the gate 20, the stop plate 26 defines at least one gate grip 29. A hinge screw 30 that inserts through the lower through holes 12 of the left side 10c and right side 10d of the rectangular cartridge 10 and the hinge through hole 22 of the gate 20 after the hinge gate through hole 22 is lined up with the lower through holes 12 of the rectangular cartridge 10, the hinge screw 30 attaches to a horizontal bar 80 of the holding bin 90. A securing screw 40 that inserts through the upper through holes 14 of the left side 10c and right side 10d of the rectangular cartridge 10 that attaches to the horizontal bar 80 of the holding bin 90. A spring 50 that is attached to the rear through hole 16 of the rectangular cartridge 10 and to the spring through hole 28. And, a lock pin 60 that inserts in the pin through hole 24 of the gate 20 when the directional drilling machine is not loading at least one pipe in the holding bin 90 of a directional drilling machine.

(8) In preferred embodiments, the support gate device 100 is made of a material that is either iron, steel or stainless steel.

(9) As seen in FIGS. 3-5, when the directional drilling machine is loading pipes into its bin 90, the lock pin 60 is removed from the pin though hole 24 of the support gate device 100.

(10) The support gate device 100 works by reducing the downward pressure that is gravitationally exerted by the pipes within the pipe holding bin on the pipes being loaded into the pipe holding bin. When the pipes are not being loaded, the gate 20 is at a rest position that supports bars resting on its top side 20e. When pipes are loaded into the bin 90, the gate 20 is pivoted upward by a pipe being pushed upward by a hydraulic lift 92 until a certain point is reached, when the certain point is reached and the gate 20 is no longer in contact with the pipe 94, the gate 20 releases to the rest position, after the gate is released to the rest position, the hydraulic lift moves downward until the pipe falls on to the top side of the gate 20 or into the bin 90.

(11) When the directional drilling machine unloads pipes, the lock pin is inserted within the pin through hole so that the pipes can freely pass downward from the bin when the hydraulic lift lowers the pipes for attachment. To insert the lock pin 60, the at least one gate grip 29 is pulled and the lock pin 60 is inserted into the pin through hole 24.

(12) In a preferred embodiment of the present invention, the directional drilling machine is a DITCH WITCH®.

(13) An advantage of the present invention is that it provides a support gate device that improves the efficiency of a directional drilling machine.

(14) Another advantage of the present invention is that it provides a support gate device that increases the life of a directional drilling machine.

(15) While the inventor's above description contains many specificities, these should not be construed as limitations on the scope, but rather as an exemplification of several preferred embodiments thereof. Accordingly, the scope should not be determined by the embodiments illustrated, but by the appended claims and their legal equivalents.
