Description

Technical Field

[0001] This utility model relates to the field of seed dryer technology, specifically to a residual grain removal mechanism for the roller discharge mechanism of a seed dryer. Background Technology

[0002] Currently, the removal of residual grain from the discharge mechanism of seed dryers relies on operators using air hoses to blow away residual grain from the bottom of the discharge rollers through observation windows, or by entering the dryer through the maintenance port of the hopper. This process requires dismantling dryer components (observation windows or maintenance doors), which is not only labor-intensive and time-consuming but also wastes valuable dryer operating time. Furthermore, operator error can lead to incomplete cleaning and mixing of different batches of seeds.

[0003] Based on this, a residual grain removal mechanism for the roller discharge mechanism of a seed dryer is provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0004] The purpose of this utility model is to provide a residual grain removal mechanism for the roller discharge mechanism of a seed dryer, so as to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A residual grain removal mechanism for a seed dryer roller discharge mechanism includes a feeding roller disposed at the dryer outlet, a welded triangle between the feeding rollers, a residual grain removal component at the lower end of the feeding roller, the residual grain removal component including a movable plate assembly connected to the lower end of the welded triangle, a linkage component on one side of the movable plate assembly, and a drive component connected to the linkage component.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0008] In one alternative: the movable plate assembly includes a sub-plate, which is located at the lower end of the welding triangle, and the sub-plate and the welding triangle are hinged together by a long chain plate.

[0009] In one alternative embodiment: the linkage component includes a cam disposed at the lower end of the sub-plate, and a hinge plate is provided between the cam and the sub-plate.

[0010] In one alternative: the hinge plate is hinged to the sub-plate and the cam via a second pin.

[0011] In one alternative: the drive assembly includes a spindle that runs through the cam, a support plate is provided in the middle of the spindle, and bearing seats are provided at both ends of the spindle.

[0012] In one alternative: the spindle and the cam are fixedly connected by a third pin.

[0013] In one alternative: a handle is provided at one end of the mandrel, the mandrel and the handle are hinged together by a first pin, and a handle holder is provided on one side of the handle.

[0014] In one alternative: the first pin, the second pin, and the third pin are all provided with cotter pins for locking.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention, through the cooperation of the movable plate assembly, linkage assembly, and drive assembly, enables the removal of residual grain without disassembling dryer components. The operator only needs to rotate the handle to complete the removal of residual grain from the roller discharge mechanism, ensuring that the residual grain is completely removed and eliminating the risk of mixing between different batches of seeds. At the same time, it effectively reduces the time spent on residual grain removal. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-3As shown, a residual grain removal mechanism of a seed dryer roller discharge mechanism includes a feeding roller 15 disposed at the discharge port of the dryer, a welded triangle 13 between the feeding rollers 15, and a residual grain removal component at the lower end of the feeding rollers 15. The residual grain removal component includes a movable plate assembly connected to the lower end of the welded triangle 13. A linkage assembly is provided on one side of the movable plate assembly, and a drive assembly is connected to the linkage assembly. In use, the movable plate assembly is driven to rotate downward by the drive assembly and the linkage assembly, thereby completing the residual grain removal work.

[0023] In one embodiment, such as Figure 3 As shown, the movable plate assembly includes a sub-plate 12, which is located at the lower end of the welded triangle 13. The sub-plate 12 and the welded triangle 13 are hinged together by a long chain plate 11. The sub-plate 12 can be rotated around the welded triangle 13 by the drive assembly and the linkage assembly.

[0024] In one embodiment, such as Figure 1 and Figure 3 As shown, the linkage component includes a cam 7 located at the lower end of the sub-plate 12. A hinge plate 14 is provided between the cam 7 and the sub-plate 12. In use, the cam 7 is driven to rotate by the drive component, and then the sub-plate 12 is driven to rotate together by the hinge plate 14.

[0025] In one embodiment, such as Figure 1 and Figure 3 As shown, the hinge plate 14 is hinged to the sub-plate 12 and the cam 7 via the second pin 8. In use, the cam 7 is driven to rotate by the drive assembly, and then the sub-plate 12 is driven to rotate together by the hinge plate 14.

[0026] In one embodiment, such as Figure 1 As shown, the drive assembly includes a spindle 2 that runs through the cam 7, a support plate 1 in the middle of the spindle 2, and bearing seats 3 at both ends of the spindle 2. In use, the cam 7 is driven to rotate by rotating the spindle 2.

[0027] In one embodiment, such as Figure 1 As shown, the spindle 2 and the cam 7 are fixedly connected by a third pin 9. In use, the cam 7 is driven to rotate by rotating the spindle 2.

[0028] In one embodiment, such as Figure 1 As shown, a handle 5 is provided at one end of the spindle 2. The spindle 2 and the handle 5 are hinged together by a first pin 4. A handle holder 6 is provided on one side of the handle 5. When in use, the spindle 2 is rotated by the handle 5, and the handle holder 6 is used to fix the handle 5.

[0029] In one embodiment, such as Figure 1The first pin 4, the second pin 8 and the third pin 9 are all provided with cotter pins 10 for locking. The cotter pins 10 are used to lock the pins and prevent the pins from coming off the components.

[0030] The above embodiment discloses a residual grain removal mechanism for the roller discharge mechanism of a seed dryer. In use, the handle 5 is removed from the handle holder 6, and then the handle 5 is rotated to drive the spindle 2 to rotate, which in turn drives the cam 7 to rotate. Then, the hinge plate 14 drives the secondary plate 12 to rotate downward around the welded triangle 13, thereby completing the residual grain removal work. Then, the handle 5 is rotated in the opposite direction to reset the secondary plate 12 and fix the handle 5 in the handle holder 6.
