When the fixed cutter fastening bolt is tightened again, the fixed position of the fixed cutter 24 on the inner wall of the crushing chamber 21 changes, so as to realize adjusting the gap between the fixed cutter 24 and the flying cutters 64 according to the requirements of the chip particle size. The discharging port of the crushing chamber 21 is connected to the feeding port of the discharging hopper 23.

[0037] In some embodiments, a shielding curtain for preventing branches and chips from rebounding is arranged at the feeding port of the feeding hopper 22, and a discharging device 25 is arranged at the discharging port of the discharging hopper 23. The arrangement of the discharging device 25 makes it easier for the chips to be discharged. (The discharging device 25 is a prior art and will not be described in detail here)

At the same time, fixing the long end and the short end of the L-shaped tensioning wheel connecting plate 216 makes the fixing of the tensioning wheel connecting plate 216 more firm.

[0040] The driving pulley 26, the crushing mechanism pulley 27, and the tensioning pulley 28 jointly support the transmission belt 29. When the gasoline engine 30 is started, the driving pulley 26 drives the crushing mechanism pulley 27 to rotate through the transmission belt 29, so as to drive the flying knife 64 in the crushing mechanism 6 to rotate, and the flying knife 64 cooperates with the fixed knife 24 to perform cutting and crushing operations.

[0041] In some embodiments, in order to improve the safety of the whole machine, protective covers 211 are arranged on both sides of the crushing bin 21 and the gasoline engine 30. Protective cover connecting rods 212 are arranged on the outer sides of the two pairs of side walls of the crushing bin 21, and the protective cover 211 is fixedly connected to the corresponding protective cover connecting rod 212.

[0042] Such asFigure 4 and Figure 5 As shown in Figure 5 , the crawler chassis 5 uses the crawler 51 to contact the ground, providing the frictional force for traveling and steering; the crawler chassis 5 includes a crawler unit, a motor 53, a worm and worm gear reducer 54 and a chassis cross beam 513. There are two crawler units, which are respectively arranged on both sides of the frame 1. The crawler unit includes a crawler 51, a driving wheel 55, a guiding wheel 56, a supporting wheel 57, a bottom plate 58, a driving wheel bracket 59, a crawler bracket 510, a driving wheel bearing seat 511 and a guiding wheel tensioning device 512.

[0043] The driving wheel 55, the guiding wheel 56 and the supporting wheel 57 are all crawler wheels and are engaged with the crawler 51. The crawler 51 is a circulating crawler, and the crawler 51 is jointly supported by the driving wheel 55, the guiding wheel 56 and the supporting wheel 57.

[0044] The driving wheel bracket 59 is vertically installed on the bottom plate 58. The bottom plate 58 is arranged on the crawler bracket 510. The bottom plate 58 is provided with mounting holes for fixing the worm and worm gear reducer 54. The housing of the motor 53 and the housing of the worm and worm gear reducer 54 are connected by bolts to ensure the stability of power transmission. The driving wheel bearing seat 511 is arranged on the driving wheel bracket 59. The driving shaft of the driving wheel 55 is arranged on the driving wheel bearing seat 511 through a bearing, realizing the fixed support of the driving wheel bracket 59 for the driving wheel 55. The output shaft of the motor 53 is connected to the input end of the worm and worm gear reducer 54, and the output end of the worm and worm gear reducer 54 is connected to the end of the driving shaft of the driving wheel 55, realizing the power transmission and effectively utilizing the self-locking function of the worm and worm gear reducer 54. In this embodiment, the motor 53 is a DC brushless motor.

[0045] The supporting wheel 57 is arranged on the crawler bracket 510. The crawler brackets 510 in the crawler units arranged on both sides of the frame 1 are connected by the chassis cross beam 513. The chassis cross beam 513 is connected to the frame 1, realizing the connection between the crawler chassis 5 and the frame 1.

[0046] Furthermore, the design of the guiding wheel 56 and the supporting wheel 57 enhances the stability and passability of the crawler chassis 5 in complex terrains. In this embodiment, the turning circle diameter of the guiding wheel 56 is 2471 - 2517 mm, and the passing circle diameter of the guiding wheel 56 is 878 - 903 mm; it can perform in-situ steering, has good passability, and can meet the operation requirements. One end of the crawler bracket 510 is welded with a guiding wheel tensioning device 512. The guiding wheel 56 is arranged on the guiding wheel tensioning device 512. By adjusting the guiding wheel tensioning device 512, the guiding wheel 56 is driven to move to realize the tensioning of the crawler 51.

[0047] As Figure 6As shown in the figure, the idler tensioning device 512 includes a guide member 514, a sliding member 515 and a tensioning bolt; the guide member 514 includes a connecting plate and two guide plates, and the same sides of the two guide plates are connected by the connecting plate. The connecting plate of the guide member 514 is fixedly connected to the crawler bracket 510. A tensioning threaded hole is provided on the connecting plate, and a chute is provided on the guide plate; the sliding member 515 includes a pushing plate and two sliding plates, and the same sides of the two sliding plates are connected by the pushing plate. The sliding plates are arranged in the corresponding chutes of the guide plates, so that the sliding member 515 can move relative to the guide member 514 along the chute direction. The idler 56 is arranged on the idler support shaft through a bearing, and both ends of the idler support shaft are fixedly connected to the corresponding sliding plates of the sliding member 515; the threaded end of the tensioning bolt is screwed into the tensioning threaded hole and is movably connected to the pushing plate of the sliding member 515. The above-mentioned movable connection is that the tensioning bolt can rotate circumferentially relative to the sliding member 515, and the tensioning bolt cannot move axially relative to the sliding member 515. When the tensioning bolt rotates in the tensioning threaded hole, the tensioning bolt drives the sliding member 515 to move, thereby driving the movement of the idler 56, realizing the movement of the position of the idler 56, and achieving the tensioning effect.

[0048] The crawler chassis 5 has the advantages of strong adaptability to hilly and mountainous terrains, small turning radius, and stable climbing.

[0049] The control box 4 is fixed on the frame 1 and is located at the tail of the crawler chassis 5. The inside includes a control system, and a signal receiving module 42, a PWM signal conversion module 43, and a motor driver 44 are installed; the power supply 52 is installed on the frame 1 and is located below the control box 4. The power supply 52 supplies power to the motor driver 44, and the motor driver 44 then supplies power to the motor 53. The control system also includes a remote control function for realizing the remote control of the crawler chassis. In this embodiment, the power supply 52 is a 48V 80AH lithium battery.

[0050] Further, as Figure 7 shown, the control system is the key to realizing the wireless remote control of the chassis. The remote control function transmits signals through the remote controller 41 and transmits the data to the signal receiving module 42 located in the control box 4. The signal output end of the signal receiving module 42 is connected to the signal input end of the PWM signal conversion module 43. After converting the received signal into a PWM signal, it is transmitted to the motor driver 44, and the motor driver 44 drives the motor 53 to realize the control of actions such as the forward, backward, and in-place turning of the crawler chassis 5.

[0051] Further, the remote controller 41 and the signal receiving module 42 in the control box communicate with each other using radio waves in the 2.4GHz frequency band, ensuring stable signal transmission and fast response. The remote controller 41 can send instructions to the signal receiving module 42 to control parameters such as the movement direction and speed of the crawler chassis 5.

[0052] Further, to ensure the normal operation of each component, the PWM signal conversion module 43 is powered by the motor driver 44, and the signal receiving module 42 is powered by the PWM signal conversion module 43.

[0053] The working principle and usage process of the present invention are as follows: The user manually remotely controls the crawler shredder through the remote controller 41. The remote controller 41 transmits data to the signal receiving module 42. The signal receiving module 42 transmits the received signal to the PWM signal conversion module 43. After converting the received signal into a PWM signal, the PWM signal conversion module 43 transmits it to the motor driver 44. The motor driver 44 drives the motor 53 to work, thereby realizing the control of actions such as the forward, backward, and in-place turning of the crawler chassis 5. When the shredder moves to the designated position, start the gasoline engine 30. After manually inserting the branches from the feed inlet of the feed hopper 22, the branches will slide into the crushing chamber 21 under the action of their own gravity. Under the cutting force of the high-speed rotation of the crushing mechanism 6, the branches will be drawn into the crushing chamber 21 and continuously cut into thin slices about 3 mm thick, and finally sprayed out from the discharge outlet of the discharge hopper 23. When it is necessary to adjust the crushing particle size of the debris, the fixed knife fastening bolt can be loosened, and the position of the fixed knife fastening bolt in the fixed knife installation slot hole can be adjusted to adjust the gap between the fixed knife 24 and the flying knife 64. After adjusting the position of the fixed knife 24, tighten the fixed knife fastening bolt to complete the adjustment.

[0054] The gasoline engine 30 can be replaced with power sources such as a diesel engine and an electric motor.

[0055] It should be noted that the embodiments described in the present invention are only examples to illustrate the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
