[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 to 5 As shown, the embodiment of the present utility model provides an efficient polyurethane sweeper, which includes a cutter bar holder 1, a blade 2 (the blade 2 is made of polyurethane material with a Shore hardness of 78 to 85 degrees), a fixed bracket 3 and a tensioning mechanism 4. An aluminum alloy base 22 is arranged on one side of the cutter bar holder 1. Two disassembly and assembly components 21 are arranged on one side of the aluminum alloy base 22. The disassembly and assembly component 21 includes a fixed block 31, an L-shaped sliding block 32, a clamping column 34 and a clamping block 24. The number of the fixed block 31, the L-shaped sliding block 32 and the clamping block 24 is two, and the number of the clamping columns 34 is four. The two fixed blocks 31 are fixedly installed on one side of the aluminum alloy base 22. The two L-shaped sliding blocks 32 are respectively slidably installed on one side of the two fixed blocks 31. The four clamping columns 34 are respectively fixedly installed on one side of the two L-shaped sliding blocks 32. Two first springs 33 are arranged between the L-shaped sliding block 32 and the fixed block 31. A clamping groove 35 is opened on one side of the fixed block 31 adjacent to the aluminum alloy base 22. Two through holes 36 are opened on one side of the inner wall of the clamping groove 35. The clamping column 34 is slidably installed in the through hole 36. The two clamping blocks 24 are fixedly installed on the lower side of the blade 2, and the two clamping blocks 24 are respectively movably inserted into the two clamping grooves 35. Two clamping slots 25 are opened on one side of the two clamping blocks 24. The clamping column 34 is movably inserted into the clamping slot 25. Pulling plates 30 are arranged on one side of the two L-shaped sliding blocks 32, and the two pulling plates 30 correspond to each other. Two connecting plates 27 are fixedly installed on one side of the aluminum alloy base 22. Two limiting sliding grooves 28 are opened on one side of the two connecting plates 27. Limiting sliding blocks 29 are fixedly installed on one side of the four pulling plates 30. The four limiting sliding blocks 29 are respectively slidably installed in the four limiting sliding grooves 28. A slot 26 is opened on the upper side of the aluminum alloy base 22. An insertion plate 23 is arranged on the lower side of the blade 2. The insertion plate 23 is movably inserted into the slot 26.

[0028] Specifically, in this embodiment, when the blade is worn or damaged and needs to be replaced, manually squeeze two adjacent pulling plates 30 simultaneously, causing the pulling plates 30 to move towards each other. When the pulling plates 30 move, they will drive the limit sliders 29 to move along the limit sliding grooves 28. Then, when the pulling plates 30 move, they will simultaneously drive two L-shaped sliding blocks 32 to move towards each other. When the two L-shaped sliding blocks 32 move towards each other, they will drive four clamping columns 34 to move towards each other, causing the four clamping columns 34 to disengage from the corresponding four clamping notches 25 respectively, thereby releasing the limit on the clamping block 24. Then, pull the blade 2 upward, causing the clamping block 24 to disengage from the clamping slot 35, and then the blade 2 can be removed. Then, during installation, reverse the above steps. Insert the insertion plate 23 of the new blade 2 into the insertion slot 26, and insert the clamping block 24 into the corresponding clamping slot 35. Then, release the pulling plates 30, causing the L-shaped sliding blocks 32 to move by the elastic force of the first spring 33. And the L-shaped sliding blocks 32 will drive the clamping columns 34 to insert into the clamping notches 25, thereby completing the installation and fixation of the blade 2. Among them, a slider is provided on one side of the L-shaped sliding block 32, and a sliding groove is provided on one side of the fixed block 31. The slider slides in the sliding groove, thereby improving the smoothness of the L-shaped sliding block 32 during movement. And two notches are provided at one end of the L-shaped sliding block 32, and one end of the first spring 33 is fixedly connected to the inner wall of the notch.

[0029] Please refer to Figures 1 to 5 As shown, the number of the fixed brackets 3 and the tensioning mechanisms 4 is two. Grooves are provided on one side of each of the two fixed brackets 3. Both ends of the tool bar holder 1 are arranged in the two grooves. Rubber nylon composite bushings 11 are provided between both ends of the tool bar holder 1 and the two grooves. The two tensioning mechanisms 4 are respectively arranged on one side of the two fixed brackets 3. The tensioning mechanism 4 specifically includes a fixed column 7, a connecting sleeve 9, a compensation plate 10, a second spring 12, a first nut 13 and a second nut 14. A fixed rod 5 is fixedly installed on one side of the fixed bracket 3. A rotating sleeve 6 is provided at one end of the fixed column 7. The rotating sleeve 6 is rotatably installed around the fixed rod 5. The compensation plate 10 is fixedly installed on one side of the connecting sleeve 9. The connecting sleeve 9 is arranged around one end of the tool bar holder 1. An adjustment groove 16 is provided on one side of the compensation plate 10. The fixed column 7 passes through the compensation plate 10 through the adjustment groove 16. A thread 15 is provided at one end of the fixed column 7. The first nut 13 and the second nut 14 are both installed on one end of the fixed column 7 through the thread 15. The second spring 12 is arranged between the first nut 13 and the compensation plate 10. A threaded cylinder 17 is provided on the lower side of the connecting sleeve 9. A fixed bolt 18 is installed in the threaded cylinder 17 by internal thread. A rubber pad is provided at one end of the fixed bolt 18. The rubber pad is in close contact with one side of the tool bar holder 1.

[0030] Specifically, in this embodiment, by rotating the first nut 13, the second spring 12 can be squeezed, causing the second spring 12 to deform. Then, the second spring 12 will provide a thrust to the compensation plate 10 through its own elastic force, causing the compensation plate 10 to drive the tool post holder 1 to rotate through the connecting sleeve 9. Then, the tool post holder 1 will drive the blade 2 to rotate, so that the blade 2 can be in good contact with the surface of the belt. Then, by adjusting the position of the first nut 13, the pressure of the second spring 12 on the compensation plate 10 can be adjusted. Then, by adjusting the second nut 14 to be in close contact with the first nut 13, the second nut 14 can limit the first nut 13 to prevent the first nut 13 from shifting.

[0031] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
