This improves threshing efficiency and extends the service life of working components.

[0040] The sealing plate can be an arc plate. The rotation angle of the sealing plate from the position of the first fixed plate to the position of the second fixed plate can be 48°, that is, the rotation angle of the first fixed plate and the second fixed plate about the hinge position of the sealing plate and the threshing concave plate fixed plate can be 48°.

[0043] The beneficial effects of adopting the above-mentioned further technical solution are: the application of the first reinforcing plate ensures the structural strength of the sealing plate and prevents the sealing plate from deforming during operation. A locking mechanism is welded to each of the first reinforcing plates on both sides of the sealing plate to fix the installation position of the sealing plate and ensure that the gap between the sealing plate and the threshing concave plate meets the working requirements.

[0044] like Figures 1 to 11 As shown, the locking mechanism is a spring pin 3.

[0045] The beneficial effects of adopting the above-mentioned further technical solutions are: it facilitates the unlocking and locking of the locking mechanism, facilitates operation, facilitates the installation and maintenance of the locking mechanism, and reduces costs.

[0046] like Figures 1 to 11 As shown, further, a plurality of connecting sleeves 4 are installed on the top of the sealing plate 1, and a plurality of mounting seats are installed on the threshing concave plate fixing plate 6. The plurality of connecting sleeves 4 are respectively connected to the plurality of mounting seats through pins 7.

[0047] The beneficial effects of adopting the above-mentioned further technical solution are: a connecting sleeve is welded to the upper end of the sealing plate, which mates with the mounting seat at the lower end of the threshing concave plate fixing plate. This facilitates the rotatable installation of the sealing plate on the threshing concave plate fixing plate, prevents axial wobbling of the sealing plate, and improves the stability and reliability of the device.

[0048] like Figures 1 to 11 As shown, the mounting base is further defined as a U-shaped mounting base 5, which has a pin hole for mounting the pin 7, and a cotter pin 8 is mounted on the free end of the pin 7.

[0049] The beneficial effect of adopting the above-mentioned further technical solution is that the connecting sleeve of the sealing plate is aligned with the pin hole on the U-shaped mounting base, and then the sealing plate is welded and fixed to the threshing concave plate fixing plate by the pin connection to form a reliable mechanical connection. The cotter pin is used to prevent the pin from falling off.

[0050] like Figures 1 to 11 As shown, the number of connecting sleeves 4 and mounting bases are both 3.

[0051] The beneficial effects of adopting the above-mentioned further technical solution are: it facilitates the rotational installation of the sealing plate on the threshing concave plate fixing plate, prevents the sealing plate from axially shaking, and improves the stability and reliability of the device.

[0052] like Figures 1 to 11As shown, a pair of second reinforcing plates 9 are further installed on both sides of the threshing concave plate.

[0053] The beneficial effect of adopting the above-mentioned further technical solution is that a first fixing plate is welded on each of the second reinforcing plates on both sides of the threshing concave plate, which provides stable support for the first fixing plate.

[0054] like Figures 1 to 11 As shown, further, a pair of second fixing plates 13 are respectively mounted on the middle partition plate 11 and the partition plate 12 by hexagon countersunk screws 14.

[0055] The beneficial effect of adopting the above-mentioned further technical solution is that it facilitates the installation and maintenance of the second fixing plate.

[0056] like Figures 1 to 11 As shown, both the first fixing plate 10 and the second fixing plate 13 are provided with locking holes adapted to the locking mechanism.

[0057] The beneficial effects of adopting the above-mentioned further technical solution are: it facilitates the insertion of the spring pin into the locking hole of the first or second fixed plate, facilitates the locking function, facilitates operation, and improves the user experience.

[0058] During the assembly of the threshing concave sealing plate (adjustable threshing concave sealing device), four first reinforcing plates 2 are firstly welded evenly to the outer surface of the sealing plate 1 to ensure the structural strength of the sealing plate and prevent deformation of the sealing plate 1 during operation. A spring pin 3 is welded to each of the first reinforcing plates 2 on both sides of the sealing plate 1 to fix the installation position of the sealing plate and ensure that the gap between the sealing plate and the threshing concave plate meets the working requirements. Three connecting sleeves 4 are welded to the upper end of the sealing plate 1, which mate with three U-shaped mounting seats 5 at the lower end of the threshing concave plate fixing plate 6 (the U-shaped mounting seats 5 are welded to the threshing concave plate fixing plate 6). During installation, the connecting sleeves 4 of the sealing plate 1 are aligned with the corresponding holes (pin holes) on the U-shaped mounting seats 5, and then the sealing plate is welded and fixed to the threshing concave plate fixing plate 6 via pins 7, forming a reliable mechanical connection. In addition, a first fixing plate 10 is welded to each of the second reinforcing plates 9 on both sides of the threshing concave plate, and a second fixing plate 13 is connected to the middle partition plate 11 and the partition plate 12 by countersunk hexagon screws 14. After the entire assembly process is completed, the sealing plate 1 and the threshing concave plate form a stable integral structure, which can adjust the angle of the sealing plate 1 under different working conditions and prevent crop stalks from accumulating or tangling between the sides of the drum and the concave plate.

[0059] like Figure 3 As shown, Figure 3The arrows in the diagram indicate the direction of drum rotation. The working principle of the threshing concave sealing plate is as follows: In existing grain harvesting machinery, after the material enters the threshing machine, it is threshed and separated under the rotation of the drum. However, due to the tangential force generated when the drum rotates counterclockwise, the amount of crop stalks accumulating at the left concave plate is significantly greater than that at the right concave plate, leading to stalk accumulation or entanglement between the left concave plate and the drum. This phenomenon can clog the gap between the left concave plate, causing localized high temperatures, damaging working parts, and significantly reducing threshing efficiency and separation effect. To solve this technical problem, this invention adds a concave sealing plate device (adjustable threshing concave sealing device) at the left concave plate, effectively improving the entanglement of crop stalks in the concave plate gap, thereby improving threshing efficiency and equipment reliability.

[0060] (1) When the large feed rate requires the threshing concave sealing plate to work.

[0061] like Figures 4 to 7 As shown, during the threshing operation of grain harvesting machinery, when a large amount of crop enters the threshing machine, the threshing plate sealing plate (sealing plate) will be in a closed state to reduce the blockage and entanglement of stalks in the gap of the left concave plate. At this time, the two spring pins 3 on the sealing plate weld (sealing plate weld) will pass through the holes (locking holes) of the first fixing plate 10 respectively, ensuring the stability and reliability of the sealing plate weld (sealing plate weld).

[0062] (2) When the small feed rate does not require the operation of the threshing concave sealing plate.

[0063] like Figures 8 to 11 As shown, during the threshing operation of grain harvesting machinery, when a small amount of crop enters the threshing machine, the stalks will not cause blockage in the gap between the left concave plates. At this time, the threshing concave plate sealing plate (sealing plate) will be in the open / closed state. To adapt to different working conditions, the operator needs to manually adjust the position of the concave plate. The specific operation is as follows: the operator holds the welded edge of the sealing plate and rotates it counterclockwise by 48° around the axis of pin 7. At this time, the two spring pins 3 on the sealing plate weld (sealing plate weld) will pass through the corresponding holes (locking holes) of the second fixed plate 13, thereby ensuring the stability and reliability of the sealing plate weld (sealing plate weld). This design can effectively adapt to the operating requirements of different feeding amounts, improve threshing efficiency and equipment operating stability.

[0064] This utility model provides an adjustable threshing concave sealing device, which can be an adjustable threshing concave sealing plate. The angle of the sealing plate can be flexibly adjusted according to different working conditions to prevent crop stalks from accumulating or tangling between the sides of the drum and the concave plate under the action of the tangential movement of the drum, which would cause blockage of the concave plate gap, trigger local high temperature, damage to working parts, and affect threshing efficiency and separation effect.

[0065] In addition, this utility model also provides a harvester, including an adjustable threshing concave sealing device as described in any one of the above.

[0066] The beneficial effects of adopting this utility model's technical solution are: it allows for flexible adjustment of the sealing plate angle according to different working conditions, effectively blocking falling grains and preventing one-sided accumulation caused by drum rotation. This improves threshing efficiency and extends the service life of working components.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
