DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The purpose of the utility model is to provide a self-propelled branch chopper to solve the problems existing in the above-mentioned prior art. The self-propelled branch chopper can move automatically, reduce labor intensity, turn flexibly, and is easy to operate.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] The utility model provides a self-propelled branch chopper. Figure 1-2As shown, it includes a chopping device, a traveling system, a first transmission assembly, a second transmission assembly and a drive device 4. The chopping device includes a chopping bin 2 and a chopping knife roller 5. The chopping knife roller 5 is rotatably arranged in the chopping bin 2 for chopping branches. The output shaft of the drive device 4 is connected to one end of the chopping knife roller 5 through the first transmission assembly. The traveling system includes two traveling wheels 7 and a differential 6. The other end of the chopping knife roller 5 is connected to the input shaft of the differential 6 through the second transmission assembly. The two output sides of the differential 6 are connected to the two traveling wheels 7 through half shafts. The output shaft of the driving device 4 drives the chopping knife roller 5 to rotate through the first transmission assembly, and the rotation of the chopping knife roller 5 drives the walking wheel 7 to move, so that the self-propelled branch chopper can move independently while chopping branches, reducing manpower control. Human assistance is only required when turning or encountering obstacles, thereby reducing the labor intensity of workers; and the turning flexibility of the self-propelled branch chopper can be improved by the differential 6. For example, when the self-propelled branch chopper turns left, the turning radius of the left wheel is smaller than the turning radius of the right wheel, that is, the left wheel speed needs to be smaller than the right wheel speed. The differential 6 is introduced between the two axles, and its "minimum energy consumption principle" is used. When the turning radii of the left and right wheels are different, the planetary gears rotate while rotating to adjust the left and right wheel speeds, so that the turning radius can be automatically adjusted. The operator can drive the differential 6 to work by slightly turning the chopper to achieve easy small-radius turning, which reduces the requirements for the use environment and is convenient for novice operation and use.

[0027] In the embodiment of the present invention, it is further preferred that the self-propelled branch shredder further comprises a feed hopper 1 and a discharge hopper 3, wherein the feed hopper 1 is connected to the feed port of the shredding bin 2, and the discharge hopper 3 is connected to the discharge port of the shredding bin 2. The feed hopper 1 has a certain height and a large opening, which is convenient for placing some longer branches or branches with many branches into the feed hopper 1 for crushing. As the branches entering the shredding bin 2 are gradually crushed, the branches in the feed hopper 1 automatically enter the shredding bin 2, thereby achieving the effect of automatic feeding, without the need for staff to manually adjust the position of the branches. The discharge hopper 3 is used to discharge the crushed branch chips from the shredding bin 2.

[0028] It is further preferred in the embodiment of the present utility model that the first transmission assembly includes a first pulley 14, a second pulley 15 and a first belt, the first pulley 14 is fixedly connected to the output shaft of the driving device 4, the first pulley 14 and the second pulley 15 are connected by a first belt 16, the second pulley 15 is fixedly connected to one end of the chopping roller 5, the second transmission assembly includes a third pulley 17, a fourth pulley 18 and a second belt 19, the third pulley 17 is fixedly connected to the other end of the chopping roller 5, the third pulley 17 and the fourth pulley 18 are connected by a second belt transmission, and the fourth pulley 18 is fixedly connected to the input shaft of the differential 6. When the self-propelled branch shredder is used, the driving device 4 is turned on, and the output shaft of the driving device 4 rotates to drive the first pulley 14 to rotate. The first pulley 14 drives the second pulley 15 to rotate through the first belt 16, and the second pulley 15 drives the chopping roller 5 to rotate. The chopping roller 5 rotates to chop the branches entering the chopping bin 2. At the same time, the chopping roller 5 rotates to drive the third pulley 17 to rotate. The third pulley 17 drives the fourth pulley 18 to rotate through the second belt 19. The fourth pulley 18 drives the input shaft of the differential 6 to rotate. The two output sides of the differential 6 are respectively connected to the two walking wheels 7 through half shafts, thereby providing power for the walking wheels 7 to travel.

[0029] In the embodiment of the present invention, it is further preferred that the self-propelled branch shredder further includes a brake system, which includes a hand brake 10, a brake bus 11, a first brake branch line 12, a second brake branch line 13, a tensioning wheel 20 and a connecting plate 21 fixedly connected to the tensioning wheel 20, such as Figure 3As shown, the first brake branch line 12 and the second brake branch line 13 are both connected to one end of the brake bus 11, and the other end of the brake bus 11 is connected to the hand brake 10. Adjusting the hand brake 10 can drive the first brake branch line 12 and the second brake branch line 13 to tighten or loosen together, and the connecting plate 21 is rotatably connected to the outer wall of the shredding bin 2 near the second belt 19. The end of the first brake branch line 12 away from the brake bus 11 is fixedly connected to the tensioning wheel 20. Tightening the first brake branch line 12 can cause the tensioning wheel 20 to swing toward the second belt 19, thereby tensioning the second belt 19. Loosening the first brake branch line 12 can cause the tensioning wheel 20 to swing away from the second belt 19, thereby loosening the second belt 19. The end of the second brake branch line 13 away from the brake bus 11 is connected to the brake pad 28 of the walking wheel 7. Tightening the second brake branch line 13 drives the brake pad 28 to hold the rotating disk of the walking wheel 7. Loosening the second brake branch line 13 causes the brake pad 28 to release the rotating disk of the walking wheel 7. When the self-propelled branch shredder needs to chop branches in a stationary state, by pulling the hand brake 10, the brake bus 11 simultaneously pulls the first brake branch line 12 and the second brake branch line 13, which can cut off the transmission connection of the walking wheel 7 and tighten the brake at the same time. The operation is convenient and the parking effect is effectively achieved. The self-propelled branch shredder can be used in more complex environments such as mountains.

[0030] like Figure 4 As shown, when the hand brake 10 is in a free state, the tensioning pulley 20 is not in contact with the second belt 19. The second belt 19 is in a relaxed state and has no tension on the second belt 19. That is, the third pulley rotates and slips against the belt, resulting in no friction and being unable to drive the travel wheel 7. When the hand brake 10 is pressed, the first brake branch line 12 pulls the tensioning pulley 20 upward, causing it to fit the second belt 19 and provide a certain amount of tension. At this time, friction is generated between the second belt 19 and the third and fourth pulleys 17, 18 to drive the travel wheel 7.

[0031] It is further preferred in the embodiment of the present invention that Figure 5As shown, the brake assembly includes a spring 29, a brake disc, a connecting rope 27 and a brake pad 28. The brake disc includes a rotating shaft 23 and a turntable with three legs. The rotating shaft 23 is fixed to the outer wall of the shredding bin 2 close to the first belt side. The turntable is rotatably connected to the rotating shaft 23. The first leg 24 of the turntable is fixedly connected to the second brake branch line 13. The second leg 25 of the turntable is fixedly connected to the brake pad 28 through the connecting rope 27. The third leg 26 of the turntable is fixedly connected to one end of the spring 29. The other end of the spring 29 is fixedly connected to the shredding bin 2 close to the first belt side. The outer wall of the side is fixedly connected, the second brake branch line 13 is loosened, the spring 29 is contracted, and the spring 29 is tightened to make the turntable rotate clockwise. The connecting rope 27 pulls the brake pads 28 to hold the rotating disk of the walking wheel 7, increasing the friction resistance and preventing it from rotating, thereby realizing the braking function, and the walking wheel 7 is in the brake stop state; tighten the second brake branch line 13, so that the turntable rotates counterclockwise, forcing the spring 29 to stretch, and the connecting rope 27 pushes the brake pads 28 to release the rotating disk of the walking wheel 7, releasing the rotating disk of the walking wheel 7, and the walking wheel 7 can move.

[0032] In an embodiment of the present invention, a plurality of limiting posts 22 are preferably provided on the side wall of the shredder bin 2 on the side closest to the second belt 19. The limiting posts 22 are located on the upper and lower sides of the second belt 19 and are configured to contact the relaxed second belt 19. When the second belt 19 is relaxed, the limiting posts 22 prevent the second belt 19 from completely falling off the third pulley 17 or the fourth pulley 18, which could cause equipment failure.

[0033] In an embodiment of the present invention, the self-propelled branch shredder further preferably includes an emergency stop device 9, which is disposed on the feed hopper 1. The drive device 4 is an engine or an electric motor, and the emergency stop device 9 is connected to the flameout device of the engine or electric motor via a pull wire. When the machine is stopped, pulling the emergency stop device 9 can shut down the engine.

[0034] It is further preferred in the embodiment of the present invention that the self-propelled branch shredder further includes an armrest 8, which is fixedly connected to the feed hopper 1, and the armrest 8 is convenient for manual grasping.

[0035] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
