To the problem that waste branch treatment processes such as economic forest, orchard, tea garden, mulberry field exist and waste time and energy, environmental pollution, wasting of resources, potential safety hazard etc. in the present, provide a suspension type branch rubbing crusher in this embodiment, its structure is as shown in attached figure 1~ 4. The suspension type branch crusher comprises a frame 1, a transmission gear box 2, a three-point suspension connecting mechanism 3 and a crushing mechanism 4. Wherein, the crushing mechanism 4 and the transmission gear box 2 are arranged on the frame 1, and the power source of the agricultural tractor is connected with the transmission gear box 2 to drive the crushing mechanism 4 to work. The three-point suspension connecting mechanism 3 is connected with one side of the frame 1.

Specifically, the frame 1 is a rectangular four-point support structure formed by welding rectangular pipes and used as a support of the whole machine tool. The lower supporting point of the frame 1 is provided with a roller 11 so as to facilitate the movement of the whole machine tool. A height regulator 12 is also arranged near the lower supporting point of the frame 1 to realize the operation on non-horizontal ground and increase the sharp adaptability.

The transmission gearbox 2 comprises a gearbox body 21, a power input shaft 22 and a power output shaft 23, and mainly realizes the purpose of converting the output standard rotating speed and direction of the tractor into the rotating speed, direction and torque required by the branch pulverizer. For example, the branch grinder in the embodiment needs an input rotating speed of 750r/min and standard output rotating speeds of 540r/min and 1100r/min of an agricultural tractor, so a transmission 2 gearbox is needed to convert the output rotating speed of the tractor into the rotating speed needed by the branch grinder.

The gearbox body 21 adopts a gear gearbox, is provided with a high speed changing function and a low speed changing function, and is controlled by the operating lever 211 to convert a two-stage speed changing function so as to adapt to various agricultural tractors. One end of the power input shaft 22 is connected with the gearbox body 21, and the other end is connected with the output shaft of the tractor through a standard spline. In this embodiment, the power input shaft 22 can be further provided with a universal hinge to realize the operation of the branch grinder and the tractor at different positions. One end of the power output shaft 23 is connected with the gearbox body 21, and the other end is connected with the crushing mechanism 4.

The three-point suspension connecting mechanism 3 is mainly used for realizing rigid connection with a tractor in the traction transportation process and the fixed-point crushing operation. The three-point suspension connecting structure 3 can be made of thickened steel pipes and steel plates, is welded at the front end of the frame 1, namely one side of the frame 1 where the power input shaft 22 is located, and has more connection reliability when three points connected with a tractor form an isosceles triangle.

And the crushing mechanism 4 is mounted on one side of the rack 1 where the power output shaft 23 is positioned in a suspended manner and is mainly used for crushing waste branches. The pulverizing mechanism 4 includes a casing 41, a feeding port 42, a discharging port 43, and a powder cutter 44. The casing 41 is in a shape of a circular cake and is formed by cutting and welding steel plates, and the axial center thereof coincides with the rotation center of the power output shaft 23. The housing 41 includes an upper housing 411 and a lower housing 412. The upper housing 411 and the lower housing 412 are welded or bolted to form a closed whole. The free end of the power output shaft 23 extends into the shell 41 and is movably connected with the wall of the shell 41. The feeding port 42 is located on a side surface of the lower case 412 far away from the transmission gearbox 2, is made of a steel plate through cutting and welding, and is connected with the lower case 412 through a bolt to achieve material guiding. The discharge hole 43 is located at the highest point of the circular arc wall of the upper housing 411, and is adjacent to one side of the housing 41 facing the transmission gearbox 2, and the discharge direction is tangential to the circular arc wall of the upper housing 411. If the dry powder cutter disc 44 is uniformly arranged on the power output shaft 23 in the casing 41, the dry powder cutter disc rotates rapidly along with the power output shaft 23 to crush the waste branches.

The powder cutter disc 44 comprises a mounting shaft sleeve 441, a fixed cutter frame 442, a fixed cutter 443, a movable cutter frame 444, a movable cutter 445 and a pin shaft 446. The mounting sleeve 441 is sleeved and fixed on the power output shaft 23. The stationary blade holder 442 is circumferentially disposed outside the mounting sleeve 441, has a length direction identical to a diameter direction of the mounting sleeve 441, and has one end connected to a surface of the mounting sleeve 441. The stationary knife 443 is mounted on the stationary knife holder 442 with the knife edge facing in the direction of rotation thereof. Two adjacent stationary blade holders 442 form a group, and both ends of the movable blade holder 444 are respectively connected with the two stationary blade holders 442 in the same group. In this embodiment, the movable blade holders 444 may also be arranged in series. In this embodiment, the fixed knives 443 of the adjacent powder cutter discs 44 are arranged in a staggered manner. The pin shaft 446 is fixed on the movable tool post 444. One end of the movable blade 445 is connected to the pin 446, and the movable blade 445 can rotate around the pin 446 as a rotation center. During the rotation of the powder cutter disc 44, the fixed cutter 443 moves relative to the waste branches and slices the waste branches. The rotation of the moving blade 445 itself can crush the waste branches for the second time.

In this embodiment, the working mode of the suspension type branch grinder is as follows:

after the agricultural tractor pulls the suspended branch grinder to a construction site, the height adjuster 12 is adjusted, and the other end of the power input shaft 22 is connected with the output shaft of the tractor and then started. The waste branches are fed into the casing 41 from the feed inlet. The powder cutter disc 44 rotates fast with the power output shaft 23 and crushes the waste branches. The material meeting the requirement of pulverization is discharged from the discharge port by the centrifugal force generated by the rotation of the powder cutter disc 44.

The suspension type branch crusher in the embodiment aims at the problems of time and labor waste, environmental pollution, resource waste, potential safety hazards and the like in the treatment process of waste branches in economic forests, orchards, tea gardens, mulberry gardens and the like; meanwhile, a suspended branch crusher with an agricultural tractor as a chassis and a power source is designed according to the existing agricultural tractor, so that waste branches generated in management processes of economic forests, orchards and the like are crushed on site, and the transportation cost and the labor cost are reduced; the waste branches are reduced from being accumulated, the disease and insect pest spreading in the garden is reduced, and the environment is purified; and the waste branches are crushed and returned to the field, so that the use of chemical fertilizers is reduced, and the resources are effectively saved. Meanwhile, the agricultural tractor is used as a chassis and a power source, so that the purchase cost of machines and tools can be reduced, the tractor can serve multiple purposes, and the resources and the cost are saved.
