Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of peanut seed screening, and more specifically, to a peanut seed screening device for peanut planting. Background Art
[0002] Peanuts, also known as groundnuts, are dicotyledonous plants with reticulate veins and seeds covered in a peanut shell. Peanuts are known for their nourishing and longevity properties, earning them the nickname "longevity fruit." Like soybeans, they are also known as "plant meat" and "the meat of vegetarians." Therefore, peanuts are an excellent plant. During peanut cultivation, a peanut seed screening device is needed to improve the overall germination rate and prevent fungal diseases.
[0003] In the existing peanut seed screening process, peanuts are poured into the hopper of the screening equipment. However, the poured peanuts often do not fall evenly on the screen, which easily leads to peanut accumulation. Some smaller peanuts and soil are screened and moved along with the accumulated peanuts, which not only easily leads to clogging of the screen but also affects the screening effect of the peanuts. In addition, the screening can only be performed based on the size of the seeds. Although this screening method can screen out qualified seeds based on size, it cannot screen out sand and gravel in the peanut seeds, resulting in unqualified peanut seeds containing soil and sand and gravel. Re-screening is required before the unqualified peanut seeds can be recycled. Utility Model Content

[0030] The rotating disk 18 is controlled to rotate by the vibration motor 17, so that one end of the push rod 19 moves with the rotation of the rotating disk 18, and pushes the screen assembly 31 on the top of the support rod 110 at the other end of the push rod 19 to swing left and right, and the inclined surface of the screen assembly 31 is used to screen the peanut seeds.
[0031] Example 2, as shown in the attached Figure 1 To the attached Figure 5 , an embodiment of the utility model provides a peanut seed screening device for peanut planting, the discharge device 2 includes a sliding plate 21 fixedly installed on the top of the fixed frame 12, the top of the right end of the sliding plate 21 is fixedly connected to a discharge hopper 22, the left side of the sliding plate 21 is fixedly connected to a discharge nozzle 25, the left side of the sliding plate 21 is internally rotatably installed with a cylindrical shaft 26, one side of the sliding plate 21 is fixedly connected to a discharge motor 24, the discharge motor 24 is fixedly connected to one side of the cylindrical shaft 26, a connecting groove 27 is opened inside the cylindrical shaft 26, and three partition plates 23 are fixedly installed inside the sliding plate 21.
[0032] like Figure 4 As shown, the partition plates 23 are V-shaped and made of rubber. Three partition plates 23 are distributed inside the sliding plate 21 in a triangle shape.
[0033] By providing the partition plate 23, when the peanut seeds are poured into the lower hopper 22, the peanut seeds roll down inside the sliding plate 21, and the partition plate 23 separates the rolled peanut seeds so that the peanut seeds are discharged from the discharge nozzle 25 in a dispersed manner, thereby avoiding the accumulation of peanut seeds and improving the screening effect of peanut seeds.
[0034] By setting the partition plate 23 to be made of rubber, it is avoided that the surface of the peanuts is damaged due to collision with the partition plate 23 during the peanut separation process, thereby affecting the germination rate of the peanut seeds.
[0035] In addition, during the process of discharging peanut seeds, the discharge motor 24 controls the rotation of the cylindrical shaft 26, so that the connecting groove 27 at one end of the discharge nozzle 25 is intermittently connected to the discharge nozzle 25, avoiding excessive discharge at one time, resulting in accumulation of peanut seeds, and then making the peanut seeds more dispersedly distributed on the top of the screen assembly 31, thereby improving the screening effect of the peanut seeds.
[0036] Example 3, as shown in the attached Figure 1 To the attached Figure 6The embodiment of the present utility model provides a peanut seed screening device for peanut planting, the screen assembly 31 includes a first screen 311, a first discharge pipe 312 is fixedly installed on the left side of the first screen 311, the first screen 311 is fixedly installed on the upper end of the fixed frame 32, the second screen 313 is fixedly installed on the lower end of the fixed frame 32, the second screen 313 is fixedly connected to the left side of the second discharge pipe 314, the left side of the second discharge pipe 314 is provided with a first discharge port, the bottom of the second screen 313 is fixedly installed with a dust collecting box 315, the left side of the dust collecting box 315 is fixedly installed with a third discharge pipe 316, and the right side of the third discharge pipe 316 is provided with a second discharge port.

The partition plates 23 are distributed in a triangular shape inside the sliding plate 21. After being separated by the first partition plate 23, the peanut seeds are discharged from both sides and are separated again by the partition plates 23 on both sides, so that the peanut seeds are discharged from the discharge nozzle 25 in a dispersed manner. During the process of discharging the peanut seeds, the discharge motor 24 controls the rotation of the cylindrical shaft 26 so that the connecting groove 27 at one end of the discharge nozzle 25 is intermittently connected to the discharge nozzle 25, so as to avoid excessive discharge at one time, which causes the accumulation of peanut seeds, and thus makes the peanut seeds more dispersedly distributed on the top of the screen assembly 31;
[0042] As the screen assembly 31 swings left and right to screen the peanut seeds, qualified peanut seeds are screened by the first screen 311 and discharged from the first discharge pipe 312, and unqualified peanut seeds are screened by the second screen 313 and discharged from the left end of the second discharge pipe 314, while soil and sand fall into the dust box 315 and are discharged through the right end of the third discharge pipe 316. Through multi-stage screening, qualified peanut seeds, unqualified peanut seeds, sand and soil are screened, which reduces subsequent processes and improves the performance of the screening device.
