Description

Technical Field

[0001] This invention specifically relates to a tree planting pit digging device for steep slope terrain, belonging to the field of forest planting technology. Background Technology

[0002] Planting trees on steep slopes is a crucial step, as it not only effectively prevents soil erosion and improves the regional ecological environment but also increases the coverage of forestry resources.

[0003] During the patent application process, a search revealed a Chinese patent with patent number CN240015045U: a digging device, comprising a base plate and a digging assembly, with four casters fixedly installed at the bottom; the digging assembly includes a guide seat, a cylindrical shell, a mounting base, a rotating shaft, a spiral blade, a motor, a mud discharge pipe, a connecting arm, and an electric push rod. The guide seat is fixedly installed on the upper part of the base plate, and the cylindrical shell is vertically and slidably installed at the center of the guide seat. The digging device provided by this utility model produces pits with smooth and compact inner walls, making them less prone to collapse. Furthermore, it eliminates the need for secondary cleaning of the excavated pits during the digging process, improving work efficiency. The discharged mud is not randomly scattered, preventing soiling of workers' clothes. Most importantly, it prevents sand and gravel in the mud from injuring workers, thus improving the safety performance of the digging device.

[0004] In the above-mentioned scheme, when digging holes for trees, the spiral blade is installed inside the cylindrical shell. After the hole is dug, the spiral blade is inside the cylindrical shell. When workers check the wear of the spiral blade, the cylindrical shell will block their view, making it impossible to observe the wear of the spiral blade. Moreover, when replacing the spiral blade, the cylindrical shell needs to be removed, which not only increases the labor intensity but also makes it difficult to accurately align the installation interface, making the operation difficult and affecting the efficiency of subsequent operations.

[0007] Furthermore, the cleaning assembly includes a turntable and a housing. The turntable is fixedly connected to one end of the mounting frame through the rotating rod. A support rod is rotatably connected to one side of the turntable via a rotating shaft. A reciprocating rod is rotatably connected to one end of the support rod via a rotating shaft. The housing is fixedly connected to one side of the mounting frame.

[0011] Beneficial effects: This invention provides a tree pit digging device for steep slope terrain. It has the following beneficial effects: 1. The adjustable components can precisely adjust the support height of the four bases according to the steep slope angle, ensuring that the base plate always remains level; 2. The lifting plate is raised and lowered by a cylinder, which in turn lowers the cylinder and spiral blades. With the help of motor one, the spiral blades are driven to rotate at high speed, enabling digging operations. At the same time, motor two drives the gear and toothed plate to mesh and drive the slide rod to slide. Then, the connecting rod pulls the stabilizing frame, causing the cylinder to be raised around the support frame shaft. This allows the staff to visually observe the wear condition of the spiral blades and facilitate timely replacement or maintenance.

[0012] 3. During the process of lifting the cylinder, the rotating rod drives the turntable to rotate, and the piston plate is driven to slide back and forth in the box through the support rod pulling the reciprocating rod. This can draw water into the box and deliver the water in the box to the hose. Finally, water is sprayed evenly onto the outer wall of the cylinder through multiple nozzles on the annular pipe, effectively removing the attached mud and impurities. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1-6 As shown, a tree planting hole digging device for steep slope terrain includes: a base plate 1, four universal wheels 101 are fixedly connected to the lower end of the base plate 1 and the four universal wheels 101 are symmetrically arranged, an adjustment component 3 is provided at the upper end of the base plate 1, and a tree planting hole digging component 4 is provided at the upper end of the base plate 1. The adjustment assembly 3 includes four adjustment cylinders 301 fixedly connected to the upper end of the base plate 1. The upper end of the base plate 1 has four holes communicating with the adjustment cylinders 301. An angle adjuster can be installed on the upper end of the base plate 1 to observe the horizontal state of the base plate 1. The angle adjuster is existing technology and will not be described further. A hydraulic cylinder 302 is fixedly connected to the upper end of each adjustment cylinder 301. A lifting column 303 is fixedly connected to the output end of the hydraulic cylinder 302. The lifting column 303 is slidably connected to the inner wall of the adjustment cylinder 301. A base 304 is hinged to the bottom end of the lifting column 303. A threaded sleeve is threadedly connected to the connection between the base 304 and the lifting column 303 to fix the base 304. In addition, a positioning rod is installed at the lower end of the base 304. The lifting column 303 is driven by four hydraulic cylinders 302 to slide along the inner wall of the adjusting cylinder 301, thereby driving the base 304 to rise and fall. The support height of the four bases 304 can be adjusted according to the inclination angle of the steep slope, so that the base plate 1 always remains horizontal.

[0017] The digging assembly 4 includes a gantry frame 401 fixedly connected to the upper end of the base plate 1. A cylinder 402 is fixedly connected to the upper end of the gantry frame 401. A lifting plate 403 is fixedly connected to the output end of the cylinder 402. Both ends of the lifting plate 403 are slidably connected to the inner wall of the gantry frame 401. Two hinge seats 404 are fixedly connected to one side of the lifting plate 403. A support frame 405 is rotatably connected to the inner wall of each of the two hinge seats 404 via a rotating shaft. A cylinder 406 is provided between the two support frames 405. A stabilizing frame 407 is fixedly connected to the outer wall of the cylinder 406. A motor 408 is fixedly connected to the upper end of the cylinder 406. A spiral blade 409 is rotatably connected to the inner wall of the cylinder 406. The output end of the motor 408 is fixedly connected to the spiral blade 409. One end of the spiral blade 409 extends out of the cylinder 406. A lifting assembly 5 is provided at the upper end of the lifting plate 403 to facilitate observation of the wear condition of the spiral blade 409. The cylinder 402 outputs the lifting plate 403 to drive the cylinder 406 to descend, and the motor 408 outputs the spiral blade 409 to rotate to perform the digging operation.

[0018] The lifting assembly 5 includes a mounting bracket 501 fixedly connected to the upper end of the lifting plate 403. A slide rod 502 is slidably connected to the outer wall of the mounting bracket 501. The two ends of the slide rod 502 are rotatably connected to the connecting rods 503 via rotating shafts. One end of each connecting rod 503 is rotatably connected to the outer wall of the stabilizing frame 407 via a rotating shaft. A toothed plate 504 is fixedly connected to the upper end of the slide rod 502. A rotating rod 505 is rotatably connected to the inner wall of the mounting bracket 501. A gear 506 is fixedly connected to the outer wall of the rotating rod 505. A second motor 507 is fixedly connected to the rear side of the mounting bracket 501. Both the first motor 408 and the second motor 507 are three-phase AC asynchronous motors capable of forward and reverse rotation. The output end of the second motor 507 is fixedly connected to the rotating rod 505. A cleaning assembly 6 for cleaning the cylinder 406 is provided on one side of the mounting bracket 501. The motor 507 drives the rotating rod 505 to rotate the gear 506. The gear 506 meshes with the toothed plate 504, which drives the slide rod 502 to slide along the mounting frame 501. Then, the connecting rod 503 pulls the stabilizing frame 407, thereby lifting the cylinder 406, which makes it easier for the staff to observe the wear condition of the spiral blade 409.

[0019] The cleaning assembly 6 includes a turntable 601 and a housing 604. A rotating rod 505 passes through one end of the outer wall of the mounting bracket 501 and is fixedly connected to the turntable 601. A support rod 602 is rotatably connected to one side of the turntable 601 via a rotating shaft. A reciprocating rod 603 is rotatably connected to one end of the support rod 602 via a rotating shaft. The housing 604 is fixedly connected to one side of the mounting bracket 501. A piston plate 605 is slidably connected to the inner wall of the housing 604. The reciprocating rod 603 passes through one end of the housing 604 and is fixedly connected to the piston plate 605. A flexible hose 606 is connected to the lower end of the housing 604. A circular annular tube 607 is installed on the outer wall of the cylinder 406. Multiple nozzles 608 are evenly spaced on the outer wall of the circular annular tube 607. The rotating rod 505 drives the turntable 601 to rotate. The turntable 601 drives the reciprocating rod 603 to reciprocate through the support rod 602, which in turn drives the piston plate 605 to slide along the inner wall of the box 604. When the piston plate 605 rises, it draws external water into the box 604 through the connecting pipe 6041. When the piston plate 605 falls, it delivers water through the hose 606 to the annular pipe 607 and sprays it out by multiple nozzles 608, which can wash the outer wall of the cylinder 406 and effectively remove the attached mud and impurities.

[0020] A connecting pipe 6041 is installed on one side of the housing 604. One-way valves are installed on the outer walls of both the connecting pipe 6041 and the flexible hose 606. The connecting pipe 6041 connects to an external water tank. The one-way valve on the outer wall of the connecting pipe 6041 prevents backflow of water entering the housing 604 from the outside. Similarly, the one-way valve on the outer wall of the flexible hose 606 prevents backflow of water from the hose into the housing 604.

[0021] The ends of both support frames 405 away from the hinge seat 404 are rotatably connected to the outer wall of the stabilizer frame 407 via a pivot. This rotatable connection between the two support frames 405 and the stabilizer frame 407 allows the cylinder 406 to rotate along the pivot of the support frame 405.

[0022] A through hole 2 is provided at the upper end of the base plate 1, and the through hole 2 is located directly below the cylinder 406. A push handle 102 is fixedly connected to one side of the base plate 1. The through hole 2 facilitates the cylinder 406 and the spiral blade 409 to pass through the base plate 1 for digging operations.

[0023] Gear 506 is located on one side of toothed plate 504, and toothed plate 504 is meshed with the tooth groove of gear 506. The meshing of gear 506 with toothed plate 504 allows slide rod 502 to slide along the inner wall of mounting bracket 501, thereby adjusting the lifting angle of cylinder 406.

[0024] The implementation principle of a tree pit digging device for steep slope terrain according to an embodiment of this application is as follows: When in use, the base plate 1 can be moved to the steep slope working area by pushing the handle 102 and the universal wheel 101. Before digging the pit, the horizontal state of the base plate 1 is observed by the tilt adjuster, and the hydraulic cylinder 302 is started to drive the lifting column 303 to slide along the inner wall of the adjusting cylinder 301, thereby driving the base 304 to rise and fall. The support height of the four bases 304 is adjusted according to the steep slope inclination angle to ensure that the base plate 1 is in a horizontal state.

[0025] When digging a hole, the cylinder 402 is started to push the lifting plate 403 down along the inner wall of the gantry frame 401, which drives the cylinder 406 to descend, so that the cylinder 406 passes through the through hole 2 and approaches the ground. The motor 408 is started to drive the spiral blade 409 to rotate, which works in conjunction with the cylinder 402 to descend and dig a hole.

[0026] However, after the pit is dug, when checking the wear condition of the spiral blade 409, the motor 507 is started to drive the rotating rod 505 and the gear 506 to rotate. The gear 506 meshes with the toothed plate 504 to drive the slide rod 502 to slide upward along the mounting frame 501. The slide rod 502 slides through the two connecting rods 503 to pull the stabilizing frame 407, so that the cylinder 406 rotates around the axis of the support frame 405 and is lifted up, making it easier for the staff to observe the wear condition of the spiral blade 409.

[0027] During the lifting of the cylinder 406, the rotating rod 505 drives the turntable 601 to rotate. The turntable 601 drives the reciprocating rod 603 to reciprocate through the support rod 602. The reciprocating rod 603 pulls the piston plate 605 to slide along the inner wall of the box 604. When the piston plate 605 rises, external water is drawn into the box 604 through the connecting pipe 6041. When the piston plate 605 falls, the water in the box 604 is transported to the annular pipe 607 through the hose 606, and then sprayed out by multiple nozzles 608 to wash away the mud and impurities attached to the outer wall of the cylinder 406.

[0028] The device is electrically connected to an external power source and a controller, which is a conventional, known device used for control.
