The circular hole concave sieve is designed aiming at the shape and the yield of special soybean crops, the circular hole diameter is 25mm, the distribution and arrangement rules adopt an intensive arrangement scheme, the threshing effect of the threshing cylinder and the concave sieve is ensured, and meanwhile, the passing performance of grains and fine impurities is improved.
As shown in figure 6, one end of a cylinder body 3-3 of the flexible threshing cylinder 3 is provided with a spiral input device 3-1, the cylinder body 3-3 is provided with a plurality of groups of threshing bulges which are uniformly distributed in the circumferential direction, each group of threshing bulges 3-2 is composed of flexible arched claws 3-2 which are distributed at intervals in the axial direction, and two ends of each flexible arched claw 3-2 are fixed on the cylinder body 3-3 at intervals in the circumferential direction to form a V-shaped ring with an outward extending fillet.
The lower part of a cover plate 1-1 of an upper cover 1 of the threshing and separating device of the embodiment is hinged with a group of middle hinge support holes 1-7 of guide plates 1-7 which are distributed at intervals along the axial direction of a flexible threshing cylinder 3 through hinge strips 1-6. The guide plate 1-7 is shown in figure 11 and comprises a top plate 1-7.2 with a middle hinge support hole, one side of the top plate is bent to form a side baffle plate 1-7.3 with the lower edge in an arc shape matched with the excircle of the threshing cylinder 3, the front end of the top plate is bent to form a front baffle plate 1-7.1 fixedly connected with the lap edge of the side baffle plate 1-7.3 in a welding way, and the rear end of the top plate is bent to form a rear foot plate 1-7.4 with a hinge hole lower than the middle hinge support hole. One end of the rear foot plate of each guide plate 1.7 is hinged through a connecting rod 1-8 respectively to form a parallel connecting rod mechanism.
The guide plate 1.7 at one end is fixedly connected with one end of the guide adjusting rod 1-3 through a hinge fulcrum shaft fixedly connected with a hinge hole in the middle of the guide plate and a connecting block 1-5. As shown in figure 10, the connecting block 1-5.1 has a main body 1-5.1 with a central through hole 1-5.2 for inserting the hinge shaft, one side of the central through hole 1-5.2 has a hinge shaft supporting hole 1-5.3, and the main body 1-5.1 extends towards two sides to form a screw hole 1-5.4 for fixing the guide flow adjusting rod 1-3.
A scale plate 1-2 for limiting the gears of the diversion adjusting rod 1-3 is fixed on the cover plate 1-1 of the upper cover. The scale plate 1-2 has stop grooves 1-2.1 with upward openings and spaced apart from each other, as shown in fig. 12, and both sides and the upper part thereof are half surrounded by a limit frame 4. The diversion adjusting rod 1-3 is made of a metal lath with the thickness matched with the width of the gear groove 1-2.1, and the end adjacent to the scale plate is formed by the right-angle torsion of the horizontal shape of the end fixedly connected with the connecting block.
When the threshing and separating device works, soybean plants are fed into the threshing chamber from the front end of the threshing cylinder, threshing is carried out under the action of the threshing cylinder and the concave plate sieve, and when the harvest feeding amount is increased or the water content of the plants is larger, the angle of the guide plate is properly adjusted and increased, so that the movement efficiency and the trafficability of crops are improved; when the harvest feeding amount is small and the plant water content is low, the angle of the guide plate is properly adjusted and reduced. When the guide plate is adjusted, the rotation of one guide plate drives other guide plates to synchronously rotate, and the adjustment of the integral angles of all the guide plates is realized. The scale plate 1-2 positions the diversion adjusting rod 1-3 to conveniently and quantitatively determine a diversion angle, when the diversion adjusting rod 1-3 is positioned at the rightmost side of the scale plate 1-2, the diversion angle is minimum, when the diversion adjusting rod 1-3 is adjusted leftwards, the diversion plate angle is increased clockwise, and when the diversion adjusting rod 1-3 is adjusted rightwards, the diversion plate angle is increased anticlockwise.
During harvesting, the yield of the soybean is increased due to the high variety and the improvement of the harvesting speed of the soybean. The threshing chamber has a certain space, and the original threshing and separating device cannot conduct diversion regulation and control, so when the feeding amount is increased, the stalks are difficult to discharge in time, internal blockage is easily caused, and faults are caused.
After the embodiment is adopted, when short soybeans are harvested, the flow guide angle, namely the included angle between the flow guide plate and the axial direction of the threshing cylinder can be adjusted to be larger; when the soybean of high and large variety is harvested, the diversion angle can be properly adjusted to be small in order to avoid blockage, so that the stalks can be discharged quickly. In addition, when the moisture content of soybean plants is high and threshing is difficult, the threshing impact force needs to be increased by increasing the rotating speed of a threshing cylinder, and if the threshing time of soybeans cannot be correspondingly adjusted, the seed crushing rate is inevitably increased, and the harvesting quality is influenced; under the condition, the stalk can be quickly discharged along the flow guide direction by adjusting the flow guide angle, so that the threshing damage of soybean seeds is reduced.
In conclusion, compared with the prior art, the threshing and separating device of the soybean harvester has the following advantages:
1) the threshing and separating device can be conveniently regulated and controlled according to different harvesting and feeding amounts, particularly under the condition of large-feeding-amount operation, realizes high-efficiency matched harvesting operation, improves threshing and separating efficiency, obviously reduces faults, improves the reliability of the whole machine, and properly solves the problem that the large-feeding-amount operation is easy to block.
2) Can be suitable for low-loss matching harvest operation under the conditions of high variety and high water content, not only is the threshing time shortened, but also the unpeeled rate and the loss of soybeans carried in the stalks can be effectively reduced.
3) The threshing cylinder with the flexible arched claw can reduce the pressure born by soybean seeds on the basis of ensuring the complete threshing of bean pods, obviously reduce the seed crushing rate in the soybean harvesting and threshing process and ensure the high-quality and high-efficiency soybean harvesting.
In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
