[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 2 - Figure 4This utility model provides an embodiment of a walnut planting hole-digging machine, including a frame 1. A mounting plate 2 is slidably connected to the outer wall of the frame 1. A motor 3 is fixedly mounted on the upper surface of the mounting plate 2. A drill bit 4 is fixedly mounted on the output end of the motor 3. The drill bit 4 is rotatably connected to the mounting plate 2 through a point. Starting the motor 3 drives the drill bit 4 to rotate at the bottom of the mounting plate 2. When the mounting plate 2 slides downwards, it drives the motor 3 and the drill bit 4 to move downwards synchronously. The downward movement of the drill bit 4 digs holes in the soil. A support plate 5 is fixedly mounted on the outer wall of the frame 1 to support... An electric push rod 6 is fixedly installed on the upper surface of plate 5. The piston end of the electric push rod 6 is fixedly installed on the upper surface of mounting plate 2. Activating the electric push rod 6 can drive the mounting plate 2 to slide up and down on the outer wall of the frame 1. A positioning mechanism is provided on the frame 1, which includes an anchoring component 7 and a limiting component 8. A cleaning component 9 is provided on the frame 1. The anchoring component 7 includes a fixing plate 71. An anchor plate 72 is fixedly installed on the lower surface of the fixing plate 71. The anchor plate 72 passes through and is slidably connected to the inner wall of the frame 1. Stepping on the pedal 76 causes the pedal 76 to drive the rotating shaft 75 to apply downward pressure to the fixing plate 71. Under pressure, the anchor plate 72 can be gradually inserted into the soil by the fixing plate 71. After the anchor plate 72 is inserted into the soil, it can strengthen the frame 1 as a whole and prevent the frame 1 from shifting due to mechanical vibration during the digging process. The inner wall of the anchor plate 72 is slidably connected to the positioning rod 73, and the side wall of the positioning rod 73 is fixedly installed with the anchor rod 74. By sliding the positioning rod 73, multiple sets of anchor rods 74 can be gradually moved out of the anchor plate 72, so that the anchor rods 74 can be inserted into the soil laterally. At this time, the anchor rods 74 can improve the tensile strength of the anchor plate 72. The anchor plate 72 is inserted more stably into the soil. The inner wall of the fixing plate 71 is rotatably connected to a rotating shaft 75. One end of the rotating shaft 75 is fixedly installed with a pedal 76, and the other end of the rotating shaft 75 is fixedly installed with a turntable 77. Rotating the rotating shaft 75 by the pedal 76 can drive the turntable 77 to rotate synchronously. The outer wall of the turntable 77 is hinged with a connecting rod 78. The end of the connecting rod 78 away from the turntable 77 is hinged to the outer wall of the positioning rod 73. The rotation of the turntable 77, in conjunction with the connecting rod 78, can push the positioning rod 73, causing the positioning rod 73 to slide on the inner wall of the anchor plate 72.
[0032] Reference Figure 2 - Figure 4The limiting component 8 includes a ball plunger 81, which is slidably connected to the inner wall of the fixed plate 71. A limiting hole 83 is provided on the frame 1. The fixed plate 71 can be limited by the ball plunger 81 in conjunction with the limiting hole 83, so that the anchor plate 72 is in a suspended state, so that the frame 1 can be moved. One end of the ball plunger 81 is attached to the inner wall of the limiting hole 83, and a spring 82 is fixedly installed at the other end of the ball plunger 81. The end of the spring 82 away from the ball plunger 81 is fixedly installed on the inner wall of the fixed plate 71. The elasticity of the spring 82 can push the ball plunger 81 into the interior of the limiting hole 83.
[0033] Reference Figure 2 - Figure 4 The cleaning component 9 includes a slide plate 91, which is slidably connected to the bottom of the frame 1. A lever 92 is fixedly installed on the lower surface of the slide plate 91. By sliding the slide plate 91 in conjunction with the lever 92, stones on the soil surface can be pushed away to prevent them from affecting the drilling of the drill bit 4. A diagonal bar 93 is fixedly installed on the top of the slide plate 91. The diagonal bar 93 is hollow. A crossbar 94 is fixedly installed on the side wall of the fixing plate 71. When the fixing plate 71 moves the anchor plate 72 downward, it will also move the crossbar 94 downward simultaneously. A guide shaft 95 is fixedly installed on the end of the crossbar 94 away from the fixing plate 71. The outer wall of the guide shaft 95 is attached to the inner wall of the diagonal bar 93. When the crossbar 94 moves downward, it can move the slide plate 91 along the bottom inner wall of the frame 1 in conjunction with the guide shaft 95 and the diagonal bar 93.
[0034] Working principle: When in use, first step on pedal 76, which drives the rotating shaft 75 to apply downward pressure to the fixing plate 71. This causes the fixing plate 71 to slide downward on the inner wall of the frame 1 along with the anchor rod 74. As the fixing plate 71 moves downward, it will drive the anchor plate 72 to gradually insert into the soil. Once the anchor plate 72 is inserted into the soil, it can reinforce the entire frame 1, preventing displacement of the frame 1 due to mechanical vibration during the digging process. This avoids deviations in the dug holes and improves the planting effect of walnut seedlings.
[0035] After the anchor plate 72 drives multiple sets of anchor rods 74 into the soil, the pedal 76 is rotated. At this time, the pedal 76 will drive the rotating shaft 75 to rotate on the inner wall of the fixed plate 71. Simultaneously, the rotating shaft 75 will drive the turntable 77 to rotate synchronously. During the rotation of the turntable 77, it will push the connecting rod 78, which in turn will push the positioning rod 73. At this time, the positioning rod 73 will slide on the inner wall of the anchor plate 72 and drive multiple sets of anchor rods 74 to gradually move out of the anchor plate 72. This allows the anchor rods 74 to be inserted laterally into the soil. At this time, the anchor rods 74 can improve the pull-out resistance of the anchor plate 72, so that the anchor plate 72 can be inserted more stably into the soil. This can further improve the stability of the frame 1 and prevent the frame 1 from shifting due to mechanical vibration.
[0036] When the foot pedal 76 is pressed, the ball head of the ball plunger 81 on the inner wall of the fixed plate 71 is squeezed by the limiting hole 83, causing the ball plunger 81 to slide inward into the fixed plate 71 and compress the spring 82. This allows the ball plunger 81 to gradually move out of the limiting hole 83. Once the ball plunger 81 has completely moved out of the limiting hole 83, the limitation on the fixed plate 71 is released. When the fixed plate 71 slides downward on the outer wall of the frame 1, it will drive the ball plunger 81 to move upward synchronously. When the ball plunger 81 moves to the limiting hole 83, the spring 82 will push the ball plunger 81, causing the ball plunger 81 to enter the interior of the limiting hole 83. At this time, the ball plunger 81, in conjunction with the limiting hole 83, can limit the fixed plate 71, thereby limiting the anchor plate 72 and keeping the anchor plate 72 in a suspended state so that the frame 1 can be moved.
[0037] As the fixed plate 71 moves the anchor plate 72 downward, it also moves the crossbar 94 downward simultaneously. As the crossbar 94 moves downward, it also moves the guide shaft 95 downward simultaneously. At this time, the guide shaft 95 will move against the inner wall of the inclined bar 93 and squeeze the inclined bar 93, causing the inclined bar 93 to push the slide plate 91. At this time, the slide plate 91 will slide on the bottom inner wall of the frame 1 and gradually move away from the turntable 77. At the same time, the slide plate 91 will drive the multiple sets of levers 92 at its bottom to move synchronously. When there are stones on the surface of the soil, the movement of the levers 92 can push away the stones on the surface of the soil, preventing the stones from affecting the drilling of the drill bit 4, thus protecting the drill bit 4 and improving its service life.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
