[0025] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 As shown, the main root cutting machine includes a frame 1, a gear transmission assembly and a chain saw transmission assembly. The lower part of the frame 1 is a rectangular structure formed by four columns. A detachable stabilizing member is connected between the upper and lower columns. The stabilizing member and the columns on the left and right sides are arranged in parallel. An inverted U-shaped mounting frame is respectively installed between the stabilizing member and the columns on both sides. The bottom of the mounting frame is connected to the side of the lowest column, and the mounting frame is arranged parallel to the column. When encountering thicker roots or hard obstacles during the cutting process, the chain saw transmission assembly and the entire frame 1 will be bounced up, so it is necessary to add a counterweight block 3 to the frame 1. Specifically, the counterweight block 3 is fixed to the mounting frame located on the right side, close to the chain saw transmission assembly, and the number of the counterweight blocks 3 can be determined according to actual needs.

[0027] like Figure 2 The upper part of the frame 1 is provided with a gear transmission assembly, and the chain saw transmission assembly is located beside the frame 1. The chain saw transmission assembly is driven to rotate by the gear transmission assembly through the drive of the hydraulic output power shaft;

[0028] The gear transmission assembly is mainly composed of a transmission shaft, a universal joint 5 and two right-angle bevel gears 4.

[0029] One end of the transmission shaft is connected to the hydraulic output power shaft, and the other end of the transmission shaft is fixedly connected to one of the right-angle bevel gears 4. The two right-angle bevel gears 4 are meshed with each other, one of the right-angle bevel gears 4 is meshed with the other right-angle bevel gear 4, and the other right-angle bevel gear 4 is connected to one end of the connecting rod. A cubic column is vertically fixed to the right part of the top column of the frame 1, and the connecting rod is horizontally inserted into the upper part of the cubic column. The other end of the connecting rod is hinged and synchronously connected to the chain saw transmission assembly through a universal joint 5.

[0030] Specifically, Figure 1 As shown, the meshing angle of the two right-angle bevel gears 4 is 90 degrees, which changes the tractor hydraulic output power shaft to a 90-degree rotation, and the angle of the universal joint 5 is 135-150 degrees, so that the output rotation power direction is tilted downward.

[0031] like Figure 3 and Figure 4 As shown, the chain saw transmission assembly includes a fixed plate, a sprocket, a tensioning wheel and a chain 6;

[0032] The fixed plate of the chain saw transmission assembly is arranged obliquely, and the middle and upper part of the fixed plate is fixed to the middle part of the frame 1 through the support rod 7. The upper and lower ends of the fixed plate are provided with sprockets. The sprocket located at the upper end of the fixed plate is coaxially fixedly connected to one end of the straight rod, and the other end of the straight rod is connected to the other end of the connecting rod of the gear transmission assembly through the universal joint 5. The middle part of the fixed plate is fixedly connected with a tensioning plate to form an integrated structure. The tensioning plate and the fixed plate are perpendicular to each other and are located in the same plane. A tensioning wheel is provided at the outer end of the tensioning plate, so that the tensioning wheel and the two sprockets are located in the same plane, and the chain 6 is meshed with the sprocket and the tensioning wheel.

[0033] A suspension frame 2 is connected to the upper side of the column located at the top of the frame 1, and moving wheels are respectively installed on both sides of the column located at the bottom. The suspension frame 2 is mainly composed of a connecting frame cross bar and two connecting frame middle bars; the two connecting frame middle bars are arranged symmetrically and obliquely. Specifically, the height of the gear transmission assembly is located in the middle position of the connecting frame middle bar, and the bottom ends of the two connecting frame middle bars are respectively connected to the top sides of the upper column of the rectangular structure of the frame 1, and the top ends of the two connecting frame middle bars are commonly connected to the horizontally arranged connecting frame cross bar, and the connecting frame cross bar is located on the upper side of the two connecting frame middle bars. A tractor upper fulcrum connecting plate is provided on the connecting frame cross bar, and two tractor lower fulcrum connecting plates are respectively connected to the two ends of the top column of the frame 1, which are connected to the connecting rod of a small and medium-sized four-wheel tractor through a three-point suspension to achieve traction and lifting of the operating machinery.

[0034] When encountering thicker roots or hard obstacles during the cutting process, the chain saw transmission assembly and the entire frame 1 will be bounced up, so it is necessary to add a counterweight 3 to the frame 1. The lower part of the frame 1 is arranged with a counterweight 3. The counterweight 3 is arranged at the lower part of the frame 1 and is close to the chain saw transmission assembly. The number of counterweights 3 can be determined according to actual needs.

[0035] During the transplanting or cutting process, cutting off the main root can help the plant adapt to the new environment faster and reduce the growth stagnation period caused by transplanting or cutting. The operation process of the main root cutting machine of the utility model is as follows:

[0036] During the taproot cutting operation, the root cutter is fixedly connected to the tractor through the tractor upper fulcrum connecting plate and the two tractor lower fulcrum connecting plates so as to be towed by the tractor. The power is output through the tractor hydraulic output power shaft to drive the transmission shaft of the root cutter to rotate, thereby driving the two right-angle bevel gears 4 with a meshing angle of 90 degrees to drive the universal joint 5 to rotate. The rotation of the universal joint 5 drives the sprocket in the chain saw transmission assembly to rotate and drive the chain to rotate quickly to achieve the root cutting work from the ground into the soil. The chain saw has greater flexibility and adaptability and can easily cope with the roots of different tree species and different root structures. The root cutter can adapt to roots of different diameters and hardness by adjusting the length and tension of the chain. Compared with the cutter, the chain saw has a more stable and powerful power system, which can provide a stable and reliable operating environment. The chain saw cutting process is also more precise, and can provide a smoother and more regular incision when cutting the root system, reducing damage and stress to the plant, which is beneficial to the growth and recovery of the plant.
