[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 5The utility model describes the above technical solution in detail through the following embodiments:

[0026] A rapeseed harvester comprises a mounting frame 1, a hydraulic cylinder 11 is arranged on the mounting frame 1, a connecting bracket 12 is arranged on the telescopic end of the hydraulic cylinder 11, a motor 2 is arranged on one side of the connecting bracket 12, a harvesting wheel 21 is arranged on the driving shaft of the motor 2, a conveyor 3 is arranged on the other side of the connecting bracket 12, a conveyor belt 31 is arranged on the conveying shaft of the conveyor 3, a linkage unit is arranged between the conveyor belt 31 and the harvesting wheel 21, and the harvesting wheel 21 drives the conveyor belt 31 to rotate through the linkage unit, so that when the motor 2 drives the harvesting wheel 21 to harvest rapeseed, the harvesting wheel 21, the linkage unit and the conveyor belt 31 are connected to the conveying shaft of the conveyor 3. The cooperation between 31 enables the harvesting wheel 21 to drive the conveyor belt 31 to rotate through the linkage unit, and then the harvested rapeseed is automatically transported to the harvester through the conveyor belt 31. A support cylinder 4 is provided on the bottom side of the connecting bracket 12, and a support wheel 41 is slidably provided on the support cylinder 4. A detection unit is provided between the support wheel 41 and the support cylinder 4, and the detection unit is used to detect the distance between the support wheel 41 and the support cylinder 4. Therefore, when the motor 2 drives the harvesting wheel 21 to harvest rapeseed, the support cylinder 4, the detection unit and the support wheel 41 cooperate to make the hydraulic cylinder 11 adjust the height of the harvesting wheel 21 in real time according to the terrain.

[0027] like Figure 2 and Figure 4 As shown, one side of the connecting bracket 12 is provided with an opening, and the harvesting wheel 21 is rotatably arranged at the opening of the connecting bracket 12 , so that the rapeseed contacts the harvesting wheel 21 from the opening of the connecting bracket 12 .

[0028] like Figure 3 and Figure 5 As shown, the linkage unit includes a linkage wheel 5, a linkage belt 51 and a connecting wheel 52. The linkage wheel 5 is rotatably arranged on the connecting bracket 12. The wheel axle of the linkage wheel 5 is connected to the wheel axle of the harvesting wheel 21. The wheel axle of the connecting wheel 52 is rotatably arranged on the conveyor 3. The linkage belt 51 is arranged on the linkage wheel 5 and the connecting wheel 52. A reverse component is arranged between the connecting wheel 52 and the conveying shaft of the conveyor 3. Therefore, through the cooperation of the linkage wheel 5, the linkage belt 51 and the connecting wheel 52, the harvesting wheel 21 drives the conveyor belt 31 to rotate, and at the same time, the counterclockwise rotation of the harvesting wheel 21 is converted into the clockwise rotation of the conveyor belt 31 through the reverse component.

[0029] like Figure 3 and Figure 5As shown, the reverse component includes a connecting gear 6 and a linkage gear 61. The connecting gear 6 is arranged on the axle of the connecting wheel 52. The linkage gear 61 is rotatably arranged on the conveyor 3. The axle of the linkage gear 61 is connected to the conveying shaft of the conveyor 3. The linkage gear 61 is meshed and linked with the connecting gear 6. Therefore, when the harvesting wheel 21 drives the connecting gear 6 to rotate counterclockwise through the cooperation of the linkage wheel 5, the linkage belt 51 and the connecting wheel 52, the counterclockwise rotation of the connecting gear 6 is converted into the clockwise rotation of the conveyor belt 31 through the linkage gear 61.

[0030] like Figure 2 and Figure 4 As shown, the support tube 4 is symmetrically arranged at the opening of the connecting bracket 12, so that the harvesting wheel 21, the support tube 4, the detection unit and the support wheel 41 are located in the same vertical plane, so that the hydraulic cylinder 11 can adjust the height of the harvesting wheel 21 in real time according to the terrain more accurately.

[0031] like Figure 4 and Figure 5 As shown, the detection unit includes a pressure sensor 7 and a detection rod 71. The pressure sensor 7 is arranged inside the support tube 4. The detection rod 71 is slidably arranged at the bottom of the support tube 4. The bottom end of the detection rod 71 extends to the bottom of the support tube 4. The support wheel 41 is arranged on the rod end of the detection rod 71 extending to the bottom of the support tube 4. A support assembly is provided between the detection rod 71 and the pressure sensor 7, so that the distance between the support wheel 41 and the support tube 4 is detected by the cooperation of the pressure sensor 7 and the detection rod 71, and at the same time, the support wheel 41 is made to contact with the ground through the support assembly.

[0032] like Figure 4 and Figure 5 As shown, the support assembly includes a support block 8 and a support spring 81. The support block 8 is arranged on the rod end of the detection rod 71 located inside the support tube 4. The support spring 81 is arranged between the support block 8 and the sensing end of the pressure sensor 7, so that the support wheel 41 is in contact with the ground through the cooperation of the support block 8 and the support spring 81, and at the same time, the distance between the support wheel 41 and the support tube 4 is detected through the cooperation of the pressure sensor 7, the detection rod 71, the support block 8 and the support spring 81.

[0033] Working principle: when the hydraulic cylinder 11 on the mounting frame 1 drives the connecting bracket 12 to slide toward the ground, the supporting wheel 41 on the connecting bracket 12 will first contact the ground, and at this time the supporting wheel 41 will drive the detecting rod 71 to slide toward the direction of the supporting tube 4, and when the detecting rod 71 slides toward the direction of the supporting tube 4, it will drive the supporting block 8 to squeeze the supporting spring 81, and at this time the supporting spring 81 will deform and transmit the squeezing force to the sensing end of the pressure sensor 7, so that the distance between the supporting wheel 41 and the supporting tube 4 can be known through the data sensed by the pressure sensor 7, and then the distance between the supporting tube 4, the connecting bracket 12 and the harvesting wheel 21 and the ground can be known, so that the hydraulic cylinder 11 The height of the harvesting wheel 21 is adjusted in real time according to the terrain. When the motor 2 drives the harvesting wheel 21 to harvest rapeseed, the wheel axle of the harvesting wheel 21 drives the linkage wheel 5 to rotate counterclockwise. When the linkage wheel 5 rotates counterclockwise, it drives the connecting wheel 52 to rotate counterclockwise through the linkage belt 51. When the connecting wheel 52 rotates counterclockwise, it drives the connecting gear 6 to rotate counterclockwise. When the connecting gear 6 rotates counterclockwise, it drives the linkage gear 61 to rotate clockwise. When the linkage gear 61 rotates clockwise, it drives the conveying shaft of the conveyor 3 to rotate clockwise, thereby making the conveyor belt 31 on the conveying shaft of the conveyor 3 rotate clockwise, and then the harvested rapeseed is automatically transported to the harvester through the conveyor belt 31.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
