DETAILED DESCRIPTION

[0018] The utility model is described below in conjunction with the accompanying drawings.

[0019] like Figure 1-3 As shown, a garbage pile drill barrel described in the utility model comprises a drill rod 1, a drill barrel body 2 and a blade group 3. The drill barrel body 2 is a cylindrical structure with a closed upper surface and an open lower surface. The blade group 3 is arranged at the bottom end of the drill barrel body 2. The drill barrel body 2 comprises an inner drill barrel 21 and an outer drill barrel 22. The drill rod 1 passes through the upper surfaces of the inner drill barrel 21 and the outer drill barrel 22, and also comprises a first bearing 4. The blade group 3 comprises an inner blade group 31 and an outer blade group 32. The inner blade group 31 and the outer blade group 32 are respectively arranged at the bottom of the inner drill barrel 21 and the outer drill barrel 22 and are arranged in a close fit; the outer drill barrel 22 is fixedly connected to the drill rod 1 all around, and the inner drill barrel 21 is rotatably connected to the drill rod 1 through the first bearing 4. A transmission device is arranged between the inner drill barrel 21 and the outer drill barrel 22, and the transmission device enables the inner drill barrel 21 and the outer drill barrel 22 to rotate in opposite directions to generate a stronger shear force.

[0020] Furthermore, in the present embodiment, the transmission device comprises a reversing gear 5, a second bearing 6, a transmission gear 7, an inner rack 211 is arranged on the inner wall of the inner drill barrel 21, the transmission gear 7 is arranged on the portion of the drill rod 1 passing through the inner drill barrel 21 and rotates coaxially with the drill rod 1, a rotating shaft 212 is also arranged on the inner upper wall of the inner drill barrel 21, the reversing gear 5 is sleeved on the rotating shaft 212 through the second bearing 6, the transmission gear 7, the reversing gear 5 and the inner rack 211 are meshed in sequence, so that when the drill rod 1 drives the outer drill barrel 22 to rotate, the transmission gear 7 on the drill rod 1 synchronously drives the reversing gear 5 to rotate in the opposite direction, and the reversing gear 5 drives the inner drill barrel 21 to rotate in the same direction through the inner rack 211, finally making the outer drill barrel 22 and the inner drill barrel 21 able to rotate synchronously in the opposite direction, thereby generating a reverse shear force at the bottom end, and producing a better cutting effect on the pile through the blade group 3.

[0021] Furthermore, the above-mentioned garbage pile drill barrel also includes a movable bottom plate 8, which is movably connected to the bottom of the outer drill barrel 22. When the movable bottom plate 8 is in a closed state, the drill barrel body 2 can be in a closed state. When the movable bottom plate 8 is opened, it can only be opened inward, and the angle between the movable bottom plate 8 and the upper surface of the outer drill barrel 22 is less than 90°, thereby ensuring that the movable bottom plate 8 can fall down by its own weight. When drilling operations are performed on the garbage pile, the cut garbage enters the drill barrel body 2, causing the movable bottom plate 8 to open inward. When the drill rod 1 is recovered, the movable bottom plate 8 falls due to its own gravity, and part of the garbage entering the drill barrel body 2 will be left in the drill barrel body 2, thereby freeing up hole space at the drilling position on the pile, which is convenient for further operations on the pile.

[0022] Furthermore, the above-mentioned garbage pile drill barrel also includes a guard plate 9, which is arranged in the inner drill barrel 21, and the drill rod 1, transmission gear 7, reversing gear 5 and inner rack 211 are enclosed between the guard plate 9 and the upper surface of the inner drill barrel 21, ensuring that the various structures are not disturbed by garbage entering the inner drill barrel 21 from the outside, so that they can operate normally.

[0023] Furthermore, the movable bottom plate 8 of the garbage pile drill tube is provided in two pieces, both of which are interactively connected with the bottom of the inner drill tube 21 and symmetrically arranged on both sides of the bottom of the inner drill tube 21. The movable bottom plate 8 is provided in two pieces so that the resistance that may be generated by the garbage in the inner drill tube 21 during the falling and closing process can be reduced.

[0024] Furthermore, the inner drill barrel 21 is provided with a groove surrounding the outer wall of the inner drill barrel 21 above the blade assembly 3, and a rubber sleeve is installed on the groove to protect the inner drill barrel 21 and the outer drill barrel 22 from garbage and debris entering.

[0025] Furthermore, the blade set 3 of the garbage pile drill barrel is configured in a sawtooth shape, which has a better cutting effect on the fibers in the garbage pile than ordinary blades.

[0026] When the garbage pile drill barrel described in this embodiment is put into use, the drill rod 1 drives the fixed outer drill barrel 22 to rotate. At this time, the transmission gear 7 installed on the drill rod 1 rotates synchronously with the outer drill barrel 22, and drives the reversing gear 5 meshing with it to rotate in the opposite direction. The reversing gear 5 further drives the inner rack 211 meshing with it to rotate in the same direction. Since the inner rack 211 is arranged on the inner wall of the inner drill barrel 21, it is equivalent to the reversing gear 5 driving the inner drill barrel 21 to rotate in the same direction, and finally the outer drill barrel 22 and the bottom of the inner drill barrel 21 generate reverse shearing force, which cooperates with the inner blade group 31 and the outer blade group 32 installed at the bottom of the inner drill barrel 21 and the outer drill barrel 22, so as to cut the fibers in the garbage pile. The serrated blade group 3 can produce a better cutting effect on the fibers in the garbage pile during the drilling process. The cut garbage pushes the movable bottom plate 8 to enter the inner drill tube 21. When the drilling is completed and the drill rod 1 is recovered, the movable bottom plate 8 falls due to its own gravity, thereby sealing part of the garbage at the drilling site into the inner drill tube 21, leaving space in the drilling hole for further processing. The garbage entering the inner drill tube 21 will not interfere with the transmission process between the drill rod 1, the transmission gear 7, the reversing gear 5 and the inner rack 211 due to the protection of the guard plate 9 and the rubber sleeve 10, so that the device can operate normally.

[0027] Compared with the prior art, the garbage pile drill described in the utility model has a better cutting effect on fibers, large-volume garbage, and elastic bodies in the garbage pile through the shear force generated by the reverse rotation of the inner drill barrel 21 and the outer drill barrel 22, in cooperation with the inner blade group 31 and the outer blade group 32, thereby solving the technical problem in the prior art that when drilling on the garbage pile, the drilling efficiency is easily affected by the interference of fibers or large-volume garbage and elastic bodies in the pile.
