Description

Technical Field

[0001] This utility model belongs to the technical field of peanut cultivation, specifically relating to a peanut seed grading and screening machine. Background Technology

[0002] With the increasing demand for standardized and high-quality seeds in modern agriculture, traditional manual screening methods can no longer meet the needs of large-scale production. Peanut seed grading and screening machines are agricultural machinery equipment specifically designed for grading and screening peanut seeds. The application of peanut seed grading and screening machines not only improves seed processing efficiency but also provides strong support for the scientific and large-scale development of agricultural production, and is an important part of the development of modern agricultural mechanization.

[0003] Chinese Patent Publication No. CN212821059U discloses a seed grading and screening machine, including a screening box containing a screening screen with unequal heights at both ends. A feed hopper is mounted on the top surface of the screening box, with its lower end above the taller end of the screening screen. A first outlet is located on the side wall of the screening box, adjacent to and above the shorter end of the screening screen. A lifting device is mounted on the outer wall of the screening box, including a lifting pipe. One end of the lifting pipe is connected to the first outlet, and the other end is connected to the feed hopper. The lifting device can lift the seeds discharged from the first outlet to the feed hopper. A second outlet is located on the side wall of the lifting pipe, with a discharge cover for sealing the second outlet. A discharge port is located at the bottom of the screening box. This application has the effect of filtering out small seeds and discharging them from the discharge port.

[0027] Example

[0028] Reference Figures 1-4 This embodiment of the present invention provides a peanut seed grading and screening machine, comprising:

[0029] The screening mechanism 100 includes a housing 101, an adjustment assembly 102 disposed in the inner cavity of the housing 101, and a guide plate 103 fixedly installed at the material outlet on the outside of the housing 101.

[0030] The support mechanism 200 includes a housing 201 fixedly installed at the bottom of the housing 101, a base 202 fixedly installed at the bottom of the housing 201, and a connecting plate 203 fixedly installed in the inner cavity of the housing 201.

[0031] Among them, by optimizing the design of the screening mechanism 100 and the carrying mechanism 200, the adaptability and screening efficiency of the equipment are significantly improved; the fine-tuning screen plate 102d and fine-tuning component 102e in the adjustment component 102 can flexibly adjust the size of the screen holes according to different varieties or specifications of peanut seeds, which solves the limitations of traditional fixed aperture screens.

[0032] Specifically, the adjustment assembly 102 includes a locking plate 102a that is movably locked in the groove on the outside of the housing 101, a handle 102b that is fixedly installed on the outside of the locking plate 102a, and a first filter screen plate 102c that is movably locked in the inner cavity of the housing 101. The adjustment assembly 102 also includes a fine-tuning screen plate 102d that is fixedly connected to the outside of the locking plate 102a, a fine-tuning component 102e that is disposed in the inner cavity of the housing 101, a positioning plate 102f that is fixedly installed in the inner cavity of the housing 101, and a positioning groove 102g that is opened at the bottom of the positioning plate 102f.

[0033] By setting the adjustment component 102 and the fine-tuning sieve plate 102d, users can flexibly adjust the size of the sieve holes according to different varieties or specifications of peanut seeds. The fine-tuning sieve plate 102d is connected to the clamping plate 102a and can be manually adjusted by the handle 102b, which solves the problem of insufficient adaptability of traditional fixed aperture sieves and improves the versatility and grading accuracy of the equipment.

[0034] Furthermore, the fine-tuning component 102e includes a return spring 102e-1 fixedly installed on the inner wall of the housing 101, a telescopic rod 102e-2 fixedly installed in the inner cavity of the return spring 102e-1, a connecting block 102e-3 fixedly installed at the end of the telescopic rod 102e-2, and a limiting block 102e-4 fixedly installed on the outside of the connecting block 102e-3. The limiting block 102e-4 is movably engaged in the inner cavity of the positioning groove 102g.

[0035] Among them, the reset spring 102e-1 and the telescopic rod 102e-2 in the fine-tuning component 102e can adjust the position of the fine-tuning screen plate 102d according to the accumulation of seeds during the screening process, so as to avoid seeds clogging the screen. The cooperation between the limiting block 102e-4 and the positioning groove 102g ensures the stability and accuracy of the fine-tuning process, effectively improving the screening efficiency.

[0036] Preferably, the screening mechanism 100 also includes a hopper 104 fixedly installed on the top of the housing 101, and a feed pipe 105 fixedly installed on the top of the hopper 104.

[0037] Among them, the material plate 103 can quickly export the graded seeds and avoid accumulation.

[0038] Furthermore, the load-bearing mechanism 200 also includes a damping damper 204 fixedly installed at the bottom of the connecting plate 203, a support rod 205 fixedly installed at the bottom of the damping damper 204, a fixing plate 206 fixedly installed on the outside of the support rod 205, and a buffer spring 207 fixedly installed on the top of the fixing plate 206, with the top of the buffer spring 207 connected to the inner wall of the housing 201.

[0039] Among them, the damping shock absorber 204 and the buffer spring 207 can effectively reduce the vibration during the operation of the equipment, and avoid seed damage or incomplete screening due to excessive vibration. The cooperation of the support rod 205 and the fixing plate 206 enhances the stability of the equipment and ensures that the screening process is smooth and efficient.

[0040] During use, peanut seeds enter the hopper 104 through the feed pipe 105 and are evenly distributed into the inner cavity of the box 101. The first filter screen 102c and the fine-tuning screen 102d in the adjustment assembly 102 grade the seeds. The fine-tuning component 102e automatically adjusts the position of the screen according to the seed accumulation to avoid clogging. The graded seeds are discharged through the guide plate 103 to complete the sieving process. The damping shock absorber 204 and the buffer spring 207 in the bearing mechanism 200 reduce equipment vibration.

[0041] In summary, by adjusting the fine-tuning screen plate 102d and fine-tuning component 102e in component 102, the size of the screen holes can be flexibly adjusted according to different varieties or specifications of peanut seeds, which solves the limitations of traditional fixed-aperture screens. The cooperation of the return spring 102e-1 and the telescopic rod 102e-2 effectively prevents seed accumulation and screen blockage, ensuring a smooth screening process. The design of the guide plate 103 and the hopper 104 optimizes the seed feeding and discharging process and improves the ease of operation. At the same time, the damping shock absorber 204 and the buffer spring 207 in the bearing mechanism 200 reduce the vibration during equipment operation, protect the seeds from damage, and improve screening accuracy.
