[0024] The left and right ends of the hollow shaft 1 are fixedly connected with connecting rods 6, and the outer surfaces of the two connecting rods 6 are rotatably connected with fixing plates 7. The hollow shaft 1 can be limited by the connecting rods 6 and the fixing plates 7, which can make it more convenient for the staff to work when using the hollow shaft 1. The connecting rods 6 are made of a material with higher hardness, which can effectively prevent the connecting rods 6 from breaking during use, effectively increasing the safety of the device.

[0025] The two fixing plates 7 are fixedly connected to a mounting plate 8 on one side away from each other, the inner wall of each mounting plate 8 is threadedly connected to a bolt 9, and the outer surface of each bolt 9 is threadedly connected to a nut 10.

[0026] The bottom end of each nut 10 is fixedly connected to a nut 11, and the outer surface of each bolt 9 is sleeved with a washer 12. The nut 11 can make it more convenient for the staff to turn the bolt 9. The washer 12 can protect the mounting plate 8, which can reduce the wear of the nut 11 on the mounting plate 8, and effectively increase the practicability of the device.

[0028] See also Figures 1 to 3The rotation of the hollow shaft 1 can drive the sleeve 201 to rotate, and then drive the root breaking knife 202 to rotate. The purpose of root breaking can be achieved through the rotation of the root breaking knife 202. The root breaking knife 202 is made of a material with relatively high hardness to avoid the root breaking knife 202 from colliding with hard substances in the soil and breaking, which can effectively increase the safety of the device. Different numbers of sleeves 201 can be set on the hollow shaft 1. By adjusting the number and distance of the sleeves 201, the device can be suitable for soils of different depths and densities, which can maximize the root breaking effect of the device and effectively increase the practicability of the device.

[0029] Four clamping blocks 13 are arranged on the outside of the hollow shaft 1, and the four clamping blocks 13 are all clamped with the hollow shaft 1. The sliding sleeve 201 can be limited by the clamping blocks 13, which can prevent the sliding sleeve 201 from falling off the hollow shaft 1, thereby increasing the safety of the device. The passivation treatment on the outer surface of the clamping blocks 13 can effectively prevent the staff from being scratched.

[0030] The inner wall of the hollow shaft 1 is rotatably connected to a threaded rod 203, the outer surface of the threaded rod 203 is threadedly connected to threaded blocks 204 arranged at equal distances, the outer surface of the threaded block 204 is hinged with a hinge column 205 through a pin, and the ends of the two hinge columns 205 that are away from each other are hinged with an insertion rod 206 through a pin, the other end of the insertion rod 206 passes through the hollow shaft 1 and is slidably connected to the hollow shaft 1, and the insertion rod 206 is plugged into the sliding sleeve 201.

[0031] See also Figures 1 to 3 The rotation of the threaded rod 203 can drive the threaded block 204 to move, and then the hinge column 205 can drive the insertion rod 206 to move, so that the insertion rod 206 can be inserted into the interior of the sliding sleeve 201, thereby achieving the purpose of limiting the sliding sleeve 201, and preventing the device from shifting during use. The outer surface of the insertion rod 206 is polished, which can reduce the wear caused by the sliding of the insertion rod 206 and effectively increase the service life of the device.

[0032] Two symmetrical sliding columns 3 are fixedly connected to the outer surface of each threaded block 204, and the ends of the two sliding columns 3 that are away from each other are slidably connected to the inner wall of the hollow shaft 1. The sliding columns 3 can limit the threaded block 204, which can prevent the threaded block 204 from shifting during movement, ensure the normal use of the device, and effectively increase the safety of the device.

[0033] The outer surface of the threaded rod 203 is fixedly connected to the first gear 207, the inner wall of the hollow shaft 1 is rotatably connected to the rotating rod 208, the outer surface of the rotating rod 208 is fixedly connected to the second gear 209, the first gear 207 is meshed with the second gear 209, and the inner wall of the rotating rod 208 is slidably connected to the sliding rod 2010.

[0034] See also Figure 4 The rotation of the slide rod 2010 can drive the rotating rod 208 to rotate, and then drive the second gear 209 to rotate. The rotation of the second gear 209 can drive the first gear 207 to rotate, and then drive the threaded rod 203 to rotate. This can make it more convenient for the staff to drive the threaded rod 203 to rotate, reduce the difficulty of operating the device, and effectively increase the practicality of the device.

[0035] The inner wall of the rotating rod 208 is slidably connected to two limit blocks 4, and the side surfaces of the two limit blocks 4 that are close to each other are fixedly connected to the outer surface of the sliding rod 2010. The sliding rod 2010 can be limited by the limit blocks 4, so that the staff can drive the rotating rod 208 to rotate when rotating the sliding rod 2010, which can ensure the normal use of the device and effectively increase the stability of the device.

[0036] The right end of the hollow shaft 1 is fixedly connected with a pull plate 5, and the outer surface of the pull plate 5 is provided with anti-slip grooves. The pull plate 5 can make it easier for the staff to rotate the slide rod 2010, and the pull plate 5 can make it more convenient for the staff to pull the slide rod 2010, which can effectively reduce the operating difficulty of the device.

[0037] Working principle: When the device is in use, the number and distance of the sliding sleeves 201 must be adjusted according to the density of the root system in the soil. When adjusting, the pull plate 5 must be pulled first, and then the sliding rod 2010 can be pulled out from the inside of the rotating rod 208. The movement of the sliding rod 2010 can drive the limit block 4 to move, and then the sliding rod 2010 is rotated, and then the limit of the limit block 4 can drive the rotating rod 208 to rotate. The rotation of the rotating rod 208 can drive the second gear 209 to rotate, and then the first gear 207 can be driven to rotate. The rotation of the first gear 207 can drive the thread The rod 203 rotates, and the rotation of the threaded rod 203 can drive the threaded block 204 to move, and then the hinge column 205 can drive the insertion rod 206 to move, so that the insertion rod 206 can be pulled out from the interior of the sliding sleeve 201, and then the limit on the sliding sleeve 201 can be released, and then the number and distance of the sliding sleeves 201 can be adjusted. After the number and distance are adjusted, the sliding rod 2010 is rotated in the opposite direction, so that the insertion rod 206 can be inserted into the interior of the sliding sleeve 201, and then the purpose of limiting the sliding sleeve 201 can be achieved, and then the device can be started to break the roots, which can ensure that the device has the maximum efficiency in breaking the root system.
