Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of harvesters, in particular to a harvester with low grain loss. Background Art
[0002] In the hilly areas of the southwest, rice, as the main food crop, has an important impact on the living standards and economic development of local farmers. In order to improve the harvesting efficiency, modern mechanical equipment, especially harvesters, have been widely introduced to replace the traditional manual harvesting method. However, although mechanization has indeed increased the harvesting speed, there are some obvious drawbacks in the design of traditional rice harvesters, which leads to unnecessary grain loss. Specifically, traditional rice harvesters usually use roller cage spiral transmission to transport the cut rice ears. However, the roller cage will generate a certain degree of centrifugal force when rotating, which will splash the grain particles on the rice ears. This design defect directly leads to a large loss of rice, seriously affecting the harvesting efficiency and farmers' income. Utility Model Content
[0003] In view of the defects in the prior art, the utility model provides a harvester with low grain loss.
[0004] A low-grain loss harvester comprises a frame body, a rolling wheel group is arranged at the bottom of the frame body, and the characteristic is that a rotating substructure is arranged at the front end of the frame body, the rotating substructure is connected to a mounting bracket, a cutting assembly is arranged at the end of the mounting bracket, a roller frame is arranged on the top surface of the mounting bracket, a gathering rod group which can rotate and face the cutting assembly is arranged on the roller frame, a transverse belt transmission assembly is also arranged on the top surface of the mounting bracket, a threshing assembly is arranged on the top of the frame body, and a lifting assembly is arranged between the threshing assembly and the mounting bracket; wherein, the left half of the transverse belt transmission assembly is located in the area between the cutting assembly and the gathering rod group, the right half of the transverse belt transmission assembly is located above the lifting assembly, and the top of the lifting assembly is located directly above the threshing assembly.
[0005] Preferably, the threshing assembly includes a threshing box and a threshing meshing wheel, a plurality of first meshing pins are distributed in a circumferential direction on the outer side of the threshing meshing wheel, and a plurality of second meshing pins are distributed on the side wall of the threshing box in an arc shape; wherein, after the threshing meshing wheel rotates, a plurality of the first meshing pins pass through the gaps between the plurality of the second meshing pins. The matching design between the threshing meshing wheel and the threshing box can efficiently remove rice from the rice ears. The staggered configuration of the first meshing pins and the second meshing pins forms a "tearing" effect when the threshing meshing wheel rotates. This design can more effectively remove the rice while avoiding excessive damage to the rice.
[0006] Preferably, the gathering rod group includes a roller body mounted on the roller frame, and a plurality of rod bodies are arranged on the outer side of the roller body in a circumferential direction. The symmetrical arrangement of the left roller and the right roller ensures the smooth operation of the first conveyor belt. This design not only improves the smoothness of transmission, but also reduces the failure rate, providing a guarantee for continuous and efficient harvesting operations.
[0007] Preferably, the transverse belt transmission assembly comprises a left roller and a right roller symmetrically arranged on the mounting bracket, and the left roller and the right roller are sleeved with a first conveyor belt. The symmetrical arrangement of the left roller and the right roller ensures the smooth operation of the first conveyor belt. This design not only improves the smoothness of the transmission, but also reduces the failure rate, thereby providing a guarantee for continuous and efficient harvesting operations.
[0008] Preferably, a plurality of friction protrusions are provided on the first conveyor belt. The provision of the friction protrusions increases the friction between the first conveyor belt and the rice ears, preventing the rice ears from slipping or rolling during the transmission process. This design ensures that the rice ears can be stably transmitted to the next processing link.
[0009] Preferably, the cutting assembly includes a set of fixed teeth and a set of movable teeth, wherein a cutting area is formed between the fixed teeth and the movable teeth. The design of the cutting assembly can efficiently and accurately cut rice ears. The cooperation of the fixed teeth and the movable teeth makes the cutting smoother while reducing the possibility of jamming and blocking. This design not only improves the harvesting efficiency, but also prolongs the service life of the equipment.
[0010] Preferably, the lifting assembly comprises a second conveyor belt arranged obliquely, and a plurality of blocking bars are arranged on the second conveyor belt. The oblique arrangement of the second conveyor belt and the configuration of the blocking bars together ensure that the rice can be smoothly lifted into the threshing assembly. The blocking bars prevent the rice from sliding or rolling off during the lifting process, thereby ensuring the continuity and efficiency of the entire harvesting process.
[0011] The beneficial effects of the utility model are embodied in:
[0012] In the entire low-grain loss harvester of the utility model, the transverse belt transmission component is characterized by stability and low vibration during the rice transmission process. This stability helps to maintain the integrity of the rice during the transmission process and avoid the scattering of grains due to severe vibration. Furthermore, compared with the traditional roller cage transmission, the transverse belt transmission has no centrifugal force generated by rotation, thereby greatly reducing the loss of mature grains due to splashing and scattering during the transmission process. This design improvement significantly improves the harvesting efficiency. Through actual use comparison tests, the results show that the harvester using the transverse belt transmission component has a higher yield per mu. The harvesting loss can be greatly reduced from the original 6% to 1%; further, the mounting bracket can rotate around the revolving pair, which means that the mounting bracket and all components thereon (such as the cutting component, the gathering rod group, the transverse belt transmission component, etc.) can freely adjust the angle and position as the terrain changes. This design enables the harvester to operate more flexibly in complex hilly terrain; further, from the cutting component to the gathering rod group, to the transverse belt transmission component, and finally the rice is sent to the threshing component through the lifting component. The entire harvesting, transmission, and threshing process is reasonably designed and smooth to operate, which can greatly improve the efficiency of the harvesting operation.
