Description

Technical Field

[0001] The utility model relates to the technical field of seed screening, and specifically relates to a impurity removing device for zucchini and pumpkin seeds. Background Art

[0002] Before seeds are sown into the land, their interior contains impurities such as dust, small particles and large particles. In order to improve the seed quality, prevent the spread of pests and diseases, and facilitate storage and transportation, it is necessary to remove the impurities contained in them through an impurity removing device; Seed impurity removing technologies include physical impurity removing (such as screening, winnowing, specific gravity separation, etc.), chemical impurity removing (such as treatment with agents), biological impurity removing (such as using biological enzymatic hydrolysis, etc.), and it is necessary to select a suitable method according to the type of seeds and the situation of impurities.

[0003] Through retrieval, the patent with the publication number CN218250784U provides a seed screening device, which includes a box body. The left side of the bottom end inside the box body is attached to the first filter box. A second filter box arranged in a left-narrow-right-wide conical shape is arranged inside the box body and the second filter box is located at the upper right side of the first filter box. Fixed parts of telescopic devices arranged horizontally are installed on the right sides of the front and rear ends of the box body. The movable parts of the telescopic devices are connected to the fixed parts of the first lifting devices arranged vertically, and the fixed parts of the two first lifting devices are respectively slidably arranged at the front and rear ends of the box body. A transverse plate arranged longitudinally is arranged on the upper side of the box body. The lower end of the transverse plate is connected to the movable parts of the two first lifting devices. Two vertical plates arranged vertically are symmetrically arranged at the lower end of the transverse plate and the vertical plates are located inside the box body. The lower parts of the two vertical plates are respectively installed on the front and rear inner walls of the second filter box. This design realizes the one-time collection of the screened defective seeds, effectively reduces the soaking time of high-quality seeds, and improves the screening quality.

[0004] However, when this utility model is in use, since filtering and screening cannot be carried out simultaneously, there are problems that the impurity removing process is relatively cumbersome during operation and it is difficult to be applicable to the water selection of a large number of seeds. Content of the Utility Model

[0005] In view of the existing problems, the utility model provides an impurity removing device for zucchini and pumpkin seeds, aiming to solve the problems that when the seed screening device mentioned in the background art is in use, since filtering and screening cannot be carried out simultaneously, there are problems that the impurity removing process is relatively cumbersome during operation and it is difficult to be applicable to the water selection of a large number of seeds.

[0006] To solve the above problems, the present utility model provides a impurity removal device for zucchini and pumpkin seeds, which includes a water selection tank. A bracket is arranged below the water selection tank. A first motor is installed on one side of the water selection tank. The lower end of the water selection tank is connected to a discharge bin. The output end of the first motor is connected to a screw blade. Both ends of the screw blade are rotatably connected to both ends of the discharge bin. An overflow port is opened above the side wall of the water selection tank. A circulation water tank is arranged on one side of the water selection tank at the overflow port. A second motor is installed on the side wall of the circulation water tank. The output end of the second motor is connected to a salvage device. One end of a circulation water pipe is connected to the lower end of the circulation water tank and close to the water selection tank, and the other end of the circulation water pipe is connected to the upper side of the water selection tank. A circulation pump is installed at the connection of the circulation water pipe and the circulation water tank.

[0007] Further, a seed discharge port is opened below one end of the discharge bin away from the water selection tank.

[0008] Further, a drain valve is installed at the bottom end of the water selection tank.

[0009] Further, the salvage device includes a rotating shaft. Both ends of the rotating shaft are rotatably connected to the side wall of the water selection tank. One side of a connecting plate is connected to the rotating shaft, and the other side of the connecting plate is connected to a salvage basket.

[0010] Further, an impurity discharge plate is arranged on one side of the salvage basket close to the rotating shaft, and a filter screen is installed at the bottom end of the salvage basket.

[0011] Further, the side of the salvage basket is in close contact with the inner wall of the circulation water tank.

[0012] The present utility model has the following beneficial effects compared with the prior art:

[0013] 1. The present utility model drives the screw blade through the first motor to convey the impurity-removed zucchini seeds out and discharge them from the seed discharge port. During the conveying process of the seeds, materials can be continuously fed into the water selection tank, and the seeds can be batch-removed of impurities. Moreover, the screw blade can also play a stirring role during the conveying process, which helps to make the light grains, empty grains and diseased and insect-infested grains in the zucchini seeds float to the water surface and flow out from the overflow port together with the excessive cleaning water.

[0014] 2. The present utility model drives the impurity removal net through the second motor to pick up the impurities floating on the water surface of the circulation water tank and discharge them from the impurity discharge port at one end, which is convenient for subsequent collection of the impurities. And the cleaning water in the circulation water tank is re-sent back to the water selection tank through the circulation water pipe by the circulation pump, so that the cleaning water can be recycled multiple times.
