[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 One embodiment provided by this utility model:
[0023] A sweet potato harvester includes a harvester body 1. A cleaning structure 2 is provided on the surface of the harvester body 1. The cleaning structure 2 includes a motor 21. A rotating shaft 22 is fixedly connected to the output end of the motor 21. A fixed roller 23 is fixedly connected to the surface of the rotating shaft 22. Four sets of mounting grooves 24 are symmetrically formed on the circumference of the surface of the fixed roller 23. A connecting groove 25 is formed inside each set of mounting grooves 24. A locking groove 26 is formed inside the connecting groove 25. Side plates 27 are rotatably connected to both sides of the fixed roller 23. A mating block 28 is fixedly connected to the surface of the side plate 27. An anti-slip pad 29 is fixedly connected to the surface of the side plate 27. Six sets of mounting structures 3 are provided inside each set of mounting grooves 24. Each mounting structure 3 includes a mounting block 31. One end of the mounting block 31 is fixedly connected to... The cleaning brush 32 has a placement groove 39 at one end of the mounting block 31. A sliding groove 33 is provided inside the mounting block 31, and a slider 34 is slidably connected inside the sliding groove 33. A spring 35 is abutted to one side of the slider 34. A connecting rod 36 is slidably connected inside the mounting block 31. A handle 37 is fixedly connected to one end of the connecting rod 36, and a locking block 38 is fixedly connected to the other end. Adjustment structures 4 are provided on both sides of the bottom of the harvester body 1. Each adjustment structure 4 includes a fixed rod 41, with an adjusting rod 42 inserted into the bottom of the fixed rod 41. A wheel 43 is rotatably connected to one side of the bottom of the adjusting rod 42. A fixing bolt 44 is rotatably connected inside the fixed rod 41. The cleaning structure 2 and the mounting structure 3 are provided, and the locking block 38 and the connecting groove 25 are used to connect them. The engagement of the engagement groove 26 and the pre-tension provided by the spring 35 enable the sweeping brush 32 to be quickly and securely engaged and fixed within the mounting groove 24. This design makes the installation and removal of the sweeping brush 32 extremely simple and quick. During operation, rotate the side plates 27 on both sides to prevent the anti-slip pads 29 from abutting against the sides of the fixed roller 23. Push inward and rotate the handle 37 to overcome the elastic force of the spring 35 and drive the locking block 38 to rotate and align with the connecting groove 25. After releasing the handle 37, the locking block 38 is pushed out of the engagement groove 26 under the action of the spring 35, allowing the mounting block 31 and the sweeping brush 32 to slide out along the mounting groove 24 for replacement. During installation, the reverse is true: after sliding the mounting block 31 into place, push the handle 37 to allow the locking block 38 to slide through the connecting groove 25 into the engagement groove 26. Inside, rotating the handle 37 drives the locking block 38 to rotate. After releasing the handle 37, the locking block 38 engages with the locking groove 26 under the action of the spring 35 to complete the locking. Then, rotating it again installs the side plate 27 on both sides of the fixed roller 23. This reduces the labor intensity and time cost of field maintenance and replacement of worn cleaning brushes 32, and improves the working efficiency of the harvester body 1. An adjustment structure 4 is set up. Through the cooperation of the fixed rod 41, the adjusting rod 42, and the fixed bolt 44 with the threaded grooves of different heights, the height of the wheel 43 off the ground can be adjusted in multiple levels. This allows the working depth of the harvester body 1 to be adjusted according to needs, significantly improving the harvester's adaptability to different working scenarios, reducing sweet potato damage or missed harvests caused by unsuitable height, and optimizing the harvest quality.
[0024] Furthermore, the motor 21 is fixedly connected to one side of the harvester body 1. The motor 21 is electrically connected to an external power source. The external power source drives the motor 21 to rotate, which in turn drives the cleaning brush 32 on the fixed roller 23 to clean the surface of the sweet potato through the rotating shaft 22.
[0025] Furthermore, the surface of the mating block 28 is provided with threads, and the two sides of the fixed roller 23 are provided with threaded grooves that match the mating block 28. The anti-slip pad 29 is made of rubber. Through the cooperation of the mating block 28 and the threaded groove, the side plate 27 is rotated and installed on both sides of the fixed roller 23. After tightening, the anti-slip pad 29 abuts against both sides of the fixed roller 23 and limits the installation structure 3.
[0026] Furthermore, the mounting block 31 is slidably connected in the mounting groove 24. The cross-sectional width of the mounting groove 24 is greater than the cross-sectional width of the connecting groove 25, and the cross-sectional width of the mounting groove 24 is less than the cross-sectional width of the engaging groove 26. The engaging block 38 is slidably connected in the connecting groove 25 and rotatably connected in the engaging groove 26. After the mounting block 31 is slid into place, push the handle 37 to make the engaging block 38 slide into the engaging groove 26 through the connecting groove 25. Rotate the handle 37 to drive the engaging block 38 to rotate. After releasing the handle 37, the engaging block 38 engages with the engaging groove 26 under the action of the spring 35 to complete the locking.
[0027] Furthermore, the radius of the slider 34 is larger than the radius of the connecting rod 36. The two ends of the spring 35 abut against the surface of the slider 34 and the inner wall of the groove 33, respectively. The spring 35 is sleeved on the outside of the connecting rod 36. The slider 34 and the groove 33 limit the movement of the connecting rod 36 to prevent the connecting rod 36 from sliding out of the mounting block 31.
[0028] Furthermore, the two ends of the connecting rod 36 pass through the slider 34 and are fixedly connected to the handle 37 and the locking block 38 respectively. The connecting rod 36, the handle 37 and the locking block 38 are rotatable structures on the mounting block 31. By pushing and pulling the handle 37, the position and angle of the locking block 38 can be adjusted.
[0029] Furthermore, the surface of the fixed rod 41 is provided with a second threaded groove, and the surface of the adjusting rod 42 is provided with four sets of third threaded grooves. The fixing bolt 44 is matched with the second and third threaded grooves. After changing the distance between the adjusting rod 42 and the fixed rod 41, the fixing bolt 44 is screwed into the corresponding third and second threaded grooves to achieve position fixation.
[0030] Working principle: During operation, the motor 21 is started, which drives the rotating shaft 22 and the fixed roller 23 to rotate. The cleaning brush 32 installed on the fixed roller 23 rotates accordingly, performing the final soil cleaning work on the sweet potato tubers dug by the sweet potato digging component or vibrating screen, making the surface of the sweet potatoes cleaner. When the cleaning brush 32 needs to be replaced, rotate the side plates 27 on both sides so that the anti-slip pads 29 no longer abut against the sides of the fixed roller 23. Push inward and rotate the handle 37 to overcome the elastic force of the spring 35 and drive the locking block 38 to rotate and align with the connecting groove 25. After releasing the handle 37, the locking block 38 is pushed out of the slot by the action of the spring 35. When the mounting block 31 and cleaning brush 32 are inserted into the mounting groove 26, they can be slid out along the mounting groove 24 for replacement. Conversely, during installation, after sliding the mounting block 31 into place, push the handle 37 to allow the locking block 38 to slide into the locking groove 26 through the connecting groove 25. Rotating the handle 37 causes the locking block 38 to rotate. Releasing the handle 37 locks the locking block 38 into the locking groove 26 under the action of the spring 35. Then, rotate the handle 37 to install the side plates 27 on both sides of the fixed roller 23. When adjusting the harvester's pickup height or digging depth, loosen the fixing bolt 44 and move the adjusting rod 42 up or down within the fixed rod 41 as needed. When the corresponding threaded groove three on the adjusting rod 42 aligns with the threaded groove two on the fixed rod 41, tighten the fixing bolt 44 so that it simultaneously screws into both the threaded groove two and the selected height threaded groove three, thus fixing the adjusting rod 42 and the wheel 43 at the new height position.
[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
