[0004] Based on the above search and combined with existing technology findings;
[0005] Although the above patent can adjust the tension of the pulley, it is adjusted by tightening the nut and the screw. Not only is the adjustment method relatively simple, but the operation is also relatively cumbersome, and the use is not convenient and efficient, so there are certain limitations. Utility Model Content
[0006] In order to solve the above technical problems, the utility model proposes a branch chipper transmission belt mechanism with adjustable tensioning force. The rotation of the tensioning wheel bracket can be well adjusted through the provided wire pull handle, thereby facilitating the rotation of the tensioning wheel, thereby realizing the regulation of the tension of the transmission V-belt.
[0007] The technical solution to achieve the purpose of the utility model is: a branch chipper transmission belt mechanism with adjustable tension, including a chassis, a knife box and a drive box fixedly mounted on the surface of the chassis, an upper cover fixedly mounted on the top of the knife box, a side of the knife box fixedly connected to a feed hopper, and also including an adjustment component.
[0008] The adjusting assembly includes a rotating shaft rotatably mounted on one side of the tool box.
[0009] In some embodiments, a driving wheel is rotatably mounted on one side of the driving box, a knife shaft is rotatably passed through one side of the knife box, a pulley is fixedly mounted on the outer peripheral wall of the knife shaft, and a transmission V-belt is commonly sleeved between the driving wheel and the pulley.

[0011] In some embodiments, a pair of handles are fixedly installed on both sides of the chassis, a fixing plate is fixedly installed on the bottom of one of the handles, a wire pull handle is rotatably installed on the fixing plate, and a fixing rod is fixedly installed on the side of the chassis close to the wire pull handle.
[0012] In some embodiments, a connecting shaft is rotatably installed between the fixed plate and the fixed rod, a U-shaped adjustment block is movably installed on the connecting shaft, an arc-shaped sliding groove is provided on the U-shaped adjustment block, the arc-shaped groove is movably fitted with the connecting shaft, and one side of the U-shaped adjustment block is rotatably connected to the wire pull handle through a movable shaft.
[0013] In some embodiments, one end of the U-shaped adjustment block is clamped with a spring, the other end of the spring is fixedly connected to a pull wire, and the other end of the pull wire is rotatably mounted on the tensioning wheel bracket.
[0014] Compared with the prior art, the present invention has the following significant advantages:
[0015] First, the utility model rotates the tensioning wheel bracket through the provided pull wire, and rotates the U-shaped adjustment block by controlling the pull wire handle, so as to facilitate pulling the pull wire and then rotating the tensioning wheel bracket, thereby rotating the tensioning wheel, thereby realizing the regulation of the tension of the transmission V-belt, so that it can be adjusted according to the working status, avoiding the transmission V-belt from being tense for a long time and causing deformation, and improving the service life of the transmission V-belt.

It also includes an adjustment component. The provided knife box 2 can realize the crushing of branches, and the provided drive box 20 can play an auxiliary role in the installation of the adjustment component. Through the provided adjustment component, the function of adjusting the tension can be well achieved.
[0026] The adjusting component includes a rotating shaft 10 rotatably mounted on one side of the tool box 2. The rotating shaft 10 can be used normally with the adjusting component.
[0027] Furthermore, a driving wheel 5 is rotatably installed on one side of the driving box 20, a knife shaft 6 is rotatably passed through one side of the knife box 2, a pulley 7 is fixedly installed on the outer peripheral wall of the knife shaft 6, and a transmission V-belt 8 is commonly sleeved between the driving wheel 5 and the pulley 7. The driving wheel 5 can rotate with the transmission V-belt 8 to drive the pulley 7 to rotate, and then rotate with the knife shaft 6, thereby achieving a branch chopping effect.
[0028] Furthermore, a tensioning wheel bracket 11 is fixedly installed on the outer peripheral wall of the rotating shaft 10, and a tensioning wheel 12 is rotatably installed on the end of the tensioning wheel bracket 11. One end of the tensioning wheel 12 is in conflict with the pulley 7. Multiple belt pressure shafts 9 are rotatably installed on one side of the tool box 2 and the drive box 20. The set rotating shaft 10 can rotate the tensioning wheel bracket 11, and then rotate the tensioning wheel 12 at the end, so as to adjust the distance between the tensioning wheel 12 and the transmission V-belt 8, thereby achieving the effect of adjusting the tension of the transmission V-belt 8.
[0029] As a further solution of the present invention, a pair of handles 14 are fixedly installed on both sides of the chassis 1, and a fixing plate 19 is fixedly installed on the bottom of one of the handles 14, and a wire pull handle 16 is rotatably installed on the fixing plate 19. A fixing rod 18 is fixedly installed on the side of the chassis 1 close to the wire pull handle 16. The set fixing plate 19 can provide support for the installation of the wire pull handle 16, and the wire pull handle 16 itself can achieve a multi-level adjustment fixing effect, and the adjustment effect can be easily achieved through the set wire pull handle 16.
[0030] Furthermore, a connecting shaft 22 is rotatably installed between the fixed plate 19 and the fixed rod 18, and a U-shaped adjustment block 17 is movably installed on the connecting shaft 22. An arc groove 21 is provided on the U-shaped adjustment block 17, and the arc groove 21 and the connecting shaft 22 are movably fitted together. One side of the U-shaped adjustment block 17 is rotatably connected to the wire pull handle 16 through a movable shaft. The wire pull handle 16 can rotate with the U-shaped adjustment block 17, and the fixed rod 18 can support the U-shaped adjustment block 17, and the arc groove 21 can ensure its normal rotation.
[0031] Furthermore, one end of the U-shaped adjustment block 17 is clamped with a spring 15, and the other end of the spring 15 is fixedly connected to a pull wire 13, and the other end of the pull wire 13 is rotatably installed on the tensioning wheel bracket 11. The U-shaped adjustment block 17 is used to work with the pull wire 13 through the spring 15, and the set pull wire 13 can rotate with the tensioning wheel bracket 11, thereby adjusting the distance between the tensioning wheel 12 and the transmission V-belt 8, and then controlling the tensioning force of the transmission V-belt 8.
[0032] The specific working method is: according to the use of the device, a driving motor is provided inside the driving box 20, and the driving motor drives the driving wheel 5 to rotate, and the wire pull handle 16 can drive the U-shaped adjustment block 17 to rotate, and the provided arc groove 21 can well ensure that the U-shaped adjustment block 17 moves with the wire pull handle 16, thereby moving with the spring 15 and the pull wire 13. The wire pull handle 16 in this device can achieve a multi-level fixing effect, so that it is convenient to adjust according to the required tensioning force. Then, the provided pull wire 13 can drive the tensioning wheel bracket 11 and the tensioning wheel 12 to rotate, thereby changing the distance between them and the transmission V-belt 8, and then adjusting the tension of the transmission V-belt 8. When the wire pull handle 16 is lifted up, the tensioning force can be increased to ensure that the transmission V-belt 8 will not slip during transmission. On the contrary, when not working, pressing the wire pull handle 16 downward can reduce the tension, avoid the transmission V-belt 8 from being tense for a long time and causing deformation, and improve the service life of the transmission V-belt 8.
