Problems solved by technology

Although the cleaning system of this technical solution uses a motor to realize the adjustment of the fan speed, it does not take into account the adjustment of the inclination angle of the vibrating screen, so it is difficult to be suitable for soybean harvesting of different varieties, planting modes, and operating conditions. There are deficiencies in efficiency and quality, and reducing cleaning losses
And it uses multiple frequency converters and multiple motors, which can only be used for indoor test benches, not for combine harvesters in field operations

Embodiment 1

[0025] The adjustable cleaning system of the soybean harvester of this embodiment is applied to the soybean combine harvester, and its basic structure is as follows figure 1 As shown, a uniform flow fan 2 is installed below the feed end of the cleaning chamber frame 1, and a vibrating screen 10 is installed in the middle layer. The main shaft of the uniform flow fan 2 is equipped with a variable diameter pulley 3, and is connected with the driving pulley 8 through a transmission belt 6 with a tension adjustment mechanism 4.

[0026] Reducer pulley 3 such as Figure 5 As shown, a pair of reducer wheels 3-1 with opposite transmission cones are connected together by bolts and nuts 3-3 that act as axial limiters, and acted by elastic members 3-2 connected between them, with Axial approach trend, maximum spacing limited by bolt length. Tension adjustment mechanism 4 see Figure 5 and Image 6 , including the tensioning rod fixing frame 5 fixed on the cleaning room frame 1 and t...

Embodiment 2

[0034] The basic structure of the adjustable cleaning system of the soybean harvester of this embodiment is the same as that of the first embodiment, and the differences are as follows: Figure 10 As shown in the figure, the hinge pins A5.1 extending from the upper and lower ends of each screen piece A5 of the rear grid screen are firstly hinged with the corresponding hinge pin holes of the upper link A3.1 and the lower link A3.2 to form The rear screen assembly of the multi-parallel four-bar linkage mechanism is assembled into the frame enclosed by the front plate, the side plates on both sides and the rear plate of the rear grid screen. The structure of the front grid screen can be analogized. In this way, the assembly is more convenient, and the inclination adjustment is more stable and reliable.

Abstract

The invention relates to an adjustable cleaning system of a soybean harvester, and belongs to the technical field of agricultural machinery. A main shaft of a uniform flow fan of the system is provided with a reducing belt wheel and is in transmission connection with a driving belt wheel through a transmission belt with a tension adjusting mechanism; a front grid screen and a rear grid screen in a vibrating screen of the system respectively comprise screen pieces which are arranged in a frame and distributed at intervals; hinge holes and receding holes which are uniformly distributed at intervals are formed in side plates of the rear grid screen; the upper ends of screen pieces of the rear grid screens are hinged to the corresponding hinge holes, and the lower ends of the screen pieces of the rear grid screens stretch out of the corresponding receding holes and then are hinged to the corresponding holes of the outer connecting rods, so that a parallel four-connecting-rod mechanism is formed. And one of the screen pieces of the rear grid screen is fixedly connected and movably connected with the upper end and the lower end of the rear adjusting handle respectively. After the soybean harvester is adopted, the rotating speed of the fan and the rear grating screen can be adjusted as required, so that the soybean harvester is suitable for harvesting and cleaning soybeans of different varieties, planting modes and working conditions, the cleaning efficiency and quality of soybean harvesting can be remarkably improved, and the cleaning loss is reduced.

Description

technical field [0001] The invention relates to a header of a harvester, in particular to an adjustable cleaning system for a soybean harvester, which belongs to the technical field of agricultural machinery. Background technique [0002] According to the applicant's understanding, the existing soybean harvest basically adopts the rice-wheat combine harvester. With the help of the traditional fish scale sieve structure, the cleaning efficiency is low, the cleaning quality is poor, and the straw and miscellaneous residues are mixed. The cleaning loss is large, and the cleaning operation parameters cannot be adjusted, so it is not to mention the soybean harvesting and cleaning that adapts to different varieties, different planting modes, and different operating conditions. After long-term research and experiments, the applicant has come to the conclusion that the most important parameters affecting the quality of the cleaning operation of the combine harvester are the rotation...
