Description

Technical Field

[0001] This utility model relates to the field of zucchini seed processing technology, and specifically discloses a zucchini seed processing impurity removal device. Background Technology

[0002] In agricultural production, seed processing is a crucial step in ensuring sowing quality, and impurity removal, as a core step in seed processing, directly affects seed purity and subsequent germination rate. Zucchini seeds often have impurities such as pulp residue, shriveled seeds, and debris adhering to their surface, which need to be removed; therefore, impurity removal equipment is required.

[0003] Existing impurity removal devices mostly use single sieving or a combination of vibrating screen and airflow for impurity removal. The method of combining vibrating screen and airflow is not convenient for removing excess pulp wrapped around the seed surface, while a single-layer screen can only remove impurities that are larger or smaller than the seed. In summary, the impurity removal effect is not good enough. Therefore, there is a need for an impurity removal device for zucchini seed processing to solve this problem. Utility Model Content

[0004] This utility model proposes a zucchini seed processing impurity removal device. The device removes excess pulp from the seed coat through an auxiliary impurity removal mechanism. It also intercepts large particles of impurities and removes fine impurities through a first filter frame and a second filter frame, thereby achieving graded removal of impurities and improving the impurity removal effect.

[0005] This utility model is implemented as follows: a zucchini seed processing impurity removal device includes a base, an auxiliary impurity removal mechanism above the base, the auxiliary impurity removal mechanism includes a tank, a cover at the upper end of the tank, a plurality of rotating shafts rotatably connected through the upper end of the cover, rubber rollers fixedly connected to the lower ends of the plurality of rotating shafts, driven gears fixedly connected to the outer walls of the plurality of rotating shafts, a motor installed at the upper end of the cover, a drive gear meshing with the plurality of driven gears fixedly connected to the output end of the motor, a discharge pipe with a butterfly valve connected to the lower end of the tank, and rubber protrusions provided on the inner wall of the tank and the outer walls of the plurality of rubber rollers.

[0006] A filtration and impurity removal mechanism is provided above the base. The filtration and impurity removal mechanism includes a first filter frame, a second filter frame, and a flow guide frame. The first filter frame, the second filter frame, and the flow guide frame are fixedly connected by a connecting rod. A driving mechanism is provided at the rear end of the flow guide frame.

[0007] As a preferred embodiment of the impurity removal device for zucchini seed processing according to this utility model, the driving mechanism includes a fixed plate fixedly connected to the rear end of the guide frame, a bracket fixedly connected to the rear end of the base, a mounting plate fixedly connected to the left end of the bracket, an electric push rod with an output end fixedly connected to the fixed plate installed on the left end of the mounting plate, and the tank body passing through and fixedly connected to the upper end of the bracket.

[0008] As a preferred embodiment of the impurity removal device for zucchini seed processing according to this utility model, the upper end of the base is provided with two impurity collection frames and a seed collection frame distributed from left to right.

[0009] As a preferred embodiment of the impurity removal device for zucchini seed processing according to this utility model, the upper end of the base has two sliding grooves distributed front and back, and the lower end of the guide frame is fixedly connected to two vertical plates distributed left and right. The lower ends of the two vertical plates are each equipped with two pulleys distributed front and back and movably connected to the two sliding grooves respectively.

The seeds rub against the multiple rubber rollers 14 and the tank 9, peeling off the surface pulp and light impurities. The rubber protrusions 15 are designed to enhance the impurity removal efficiency. The processed seeds mixed with impurities fall from the discharge pipe 16 into the lower filtration and impurity removal mechanism through the butterfly valve. The first filter frame 4 intercepts large particles of impurities, and the seeds and small particles of impurities fall through the mesh to the second filter frame 5. The second filter frame 5 further screens out fine impurities. The fine impurities fall through the mesh into the bottom guide frame 6, realizing graded removal and improving the impurity removal effect.

[0026] As a technical optimization of this utility model, the driving mechanism includes a fixed plate 17 fixedly connected to the rear end of the guide frame 6, a bracket 8 fixedly connected to the rear end of the base 1, a mounting plate 19 fixedly connected to the left end of the bracket 8, an electric push rod 18 with its output end fixedly connected to the fixed plate 17 installed on the left end of the mounting plate 19, and a tank 9 penetrating through and fixedly connected to the upper end of the bracket 8.

[0027] In this embodiment, the electric actuator 18 can drive the fixed plate 17 and the flow guide frame 6 to move back and forth, which can promote the flow of materials inside the first filter frame 4, the second filter frame 5 and the flow guide frame 6.

[0028] As a technical optimization of this utility model, the upper end of the base 1 is provided with two impurity collection frames 3 and seed collection frames 2 distributed from left to right.

[0029] In this embodiment: the impurity collection box 3 is used to collect impurities inside the first filter box 4 and the guide box 6, and the seed collection box 2 is used to collect impurities after impurity removal.

[0030] As a technical optimization of this utility model, the upper end of the base 1 is provided with two sliding grooves distributed front and back, and the lower end of the guide frame 6 is fixedly connected with two vertical plates 22 distributed left and right. The lower ends of the two vertical plates 22 are each equipped with two pulleys distributed front and back and movably connected to the two sliding grooves respectively.

[0033] In this embodiment, the mesh size of the first filter frame 4 is larger than that of the second filter frame 5, which can easily intercept large particles of impurities, while allowing fine impurities and seeds to fall into the upper part of the second filter frame 5, and the fine impurities can be easily removed through the mesh size of the second filter frame 5.

[0034] As a technical optimization of this utility model, the upper end of the cover 20 is connected to multiple feed pipes 21.

[0035] In this embodiment, multiple feed pipes 21 can conveniently and evenly feed seeds containing impurities into the cover 20.

[0038] The working principle and usage process of this utility model are as follows: When in use, the seeds are evenly fed into the tank 9 through multiple feed pipes 21 on the cover 20. The motor 10 is started, and the drive gear 11 drives multiple driven gears 13 to rotate synchronously, driving the rotating shaft 12 and the rubber roller 14 to rotate at high speed. The rubber protrusions 15 on the surface of the rubber roller 14 and the protrusions on the inner wall of the tank 9 form a flexible friction area. The seeds rub against the multiple rubber rollers 14 and the tank 9 to peel off the surface pulp and light impurities. The rubber protrusions 15 are designed to enhance the impurity removal efficiency.

[0039] The processed seeds mixed with impurities fall from the discharge pipe 16 into the lower filtration and impurity removal mechanism through the butterfly valve. The electric push rod 18, activated by the controller, drives the fixed plate 17 and the guide frame 6 to move back and forth, which promotes the material flow inside the first filter frame 4, the second filter frame 5, and the guide frame 6. The first filter frame 4 intercepts large particles of impurities and they fall into the impurity collection frame 3. Seeds and small particles of impurities fall through the mesh to the second filter frame 5. Seeds fall into the seed collection frame 2. The second filter frame 5 further screens out fine impurities.
