Description

Technical Field

[0001] The utility model belongs to the field of agricultural equipment, in particular to a threshing device and a diversion angle adjusting device. Background Art

[0002] The threshing and separation device is the core operating component of the corn grain harvester. The threshing quality directly affects the quality and yield of corn. When harvesting corn ears with high moisture content (≥25%), the existing corn threshing and separation devices generally have problems such as high grain breakage rate, high unthreshed rate and high operating energy consumption, which has become a bottleneck restricting the development of corn grain harvesting technology.

[0003] The adjustment of the diversion angle of the threshing device has a significant impact on the threshing quality and threshing loss. Under the condition of a certain feed amount, when the diversion angle is small, the axial movement speed of the corn cob inside the threshing device becomes smaller, and the threshing time of the cob is longer, resulting in an increase in the crushing rate of the cob grains, and it is easy to get blocked, reducing the threshing efficiency; when the diversion angle is large, the movement speed of the corn cob inside the threshing device increases, the threshing time of the cob becomes shorter, and the grains and debris are not fully separated and discharged from the threshing device, resulting in an increase in the rate of incomplete threshing and loss rate of the cob. Therefore, it is necessary to reasonably adjust the diversion angle according to the size of the feed amount, which helps to improve the threshing efficiency and threshing quality of the threshing device.

[0022] The following is combined with Figure 1-6 , the specific implementation methods of the utility model are described in detail. The implementation methods are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model. Obviously, the embodiments described in the utility model 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 those skilled in the art without making creative work are within the scope of protection of the utility model.

[0023] like Figure 1 As shown, the threshing device guide angle adjustment device is installed on the threshing device body, the threshing device body includes a threshing drum 5, and the threshing device body is fixed with multiple support plates 7. The threshing device guide angle adjustment device mainly includes a bearing seat 1, a connecting rod 3, a driven rod 4, a guide plate 6, a bottom plate 2, an active rod 8, a guide angle adjustment electric push rod 9, a fixed seat 10, and an arc-shaped top plate 11.

[0024] like Figure 3 As shown, a plurality of bearing seats 1 are arranged in a row and installed on a base plate 2, and the base plate 2 is fixed to an arc-shaped top plate 11 by bolt connection, and the arc-shaped top plate 11 is fixed to a support plate 7. A guide plate 6 is rotatably installed on each bearing seat 1. The first end of the active rod 8 is hinged to the first end of the connecting rod 3, and the other end is hinged to the rod head of the electric push rod 9 for adjusting the diversion angle. The connecting rod 3 is hinged to the first ends of the four driven rods 4 in sequence from the first end to the second end. The outermost guide plate 6 on the base plate 2 is connected to the middle part of the active rod 8. The remaining four guide plates 6 are respectively connected to the second end of a connecting rod. The main body of the guide plate 6 and the connecting rod 3 are respectively located on both sides of the arc-shaped top plate 11.

[0025] The deflector plate 6 can rotate freely around the bearing seat. Since the deflector plate 6, the active rod 8 and the driven rod 4 are connected together by the connecting rod 3, the rotation angles of the three are consistent. When the deflector angle adjustment electric push rod 9 drives the active rod 8 to rotate a certain angle, the deflector plate 6 will also rotate the same angle. The rod seat of the deflector angle adjustment electric push rod 9 is hinged to the fixed seat 10, and the fixed seat 10 is fixed to the arc-shaped top plate 11. The fixed seat 10 is located on the outside of the bottom plate 2.

[0026] like Figure 4 , Figure 5 As shown, the diversion angle refers to the angle θ between the diversion plate 6 and the vertical direction. The diversion plate 6 rotates around the central fulcrum, and the adjustment range can reach 0-60°. The diversion angle and the extension amount of the diversion angle adjustment electric push rod 9 are in a good linear relationship.

[0027] like Figure 4 , Figure 5 , Figure 6As shown in FIG. 1 , they are schematic diagrams of the structures of the active rod 8, the driven rod 4 and the guide plate 6. Figure 4 As shown, the active rod 8 has a mounting sleeve in the middle of the rod body, a pin hole is opened on the two opposite walls of the mounting sleeve, and a hinge hole is opened at both ends of the active rod 8; Figure 5 As shown, the first end of the driven rod 4 is provided with a hinge hole, the second end is provided with a mounting sleeve, and the two opposite walls of the mounting sleeve are respectively provided with a pin shaft hole; Figure 6 As shown, the guide plate 6 has an arc-shaped body, a connecting shaft is provided in the middle, and a pin shaft hole is provided at the end of the connecting shaft.

[0028] During installation, the guide plate 6 is inserted into the bearing of the bearing seat 1 from one end of the bearing seat through the top connecting shaft, and exposed from the other end of the bearing seat 1. The exposed part passes through the mounting sleeves of the active rod 8 and the driven rod 4 respectively, and the hinge hole at the top of the exposed part of the connecting shaft is connected to the pin shaft hole on the mounting sleeve of the active rod 8 and the driven rod 4 respectively through a pin to ensure that the rotation angles of the three are consistent. A gap with a width of 1m is also opened on the mounting sleeve of the active rod 8, and the gap is connected with a hinge hole, which can buffer the force generated by the corn ear flow on the guide plate 6 during the threshing process to a certain extent and transmit it to the electric push rod 9 for adjusting the diversion angle, which plays a certain protective role on the electric push rod 9 for adjusting the diversion angle.

[0029] When working, the control system of the threshing device adjusts the diversion angle and the extension amount of the electric push rod 9 according to the feeding amount, driving the active rod 8 to swing, thereby the driven rod swings with it, and the angle of the guide plate 6 can be conveniently adjusted.

[0030] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in this application should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
