When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0039] Example 1

[0040] like Figure 1-6 As shown, the utility model provides a technical solution: a cleaning and screening equipment for rice seed research and development, comprising a cleaning box 1 and a cleaning cover 11, the cleaning cover 11 is placed on the cleaning box 1, a driving motor 2 is installed on one side of the cleaning box 1, the output end of the driving motor 2 extends to the inside of the cleaning box 1 and a first mounting bracket 3 is installed, corresponding to the first mounting bracket 3 and rotatably connected to the other inner wall of the cleaning box 1 with a second mounting bracket 4, a filter structure 5 is installed on the first mounting bracket 3 and the second mounting bracket 4, the cleaning box 1 is connected to a water inlet pipe 6 and a water outlet pipe 7 arranged above and below, and the water inlet pipe 6 and the water outlet pipe 7 are respectively connected to external water inlet and drainage pipes.

[0041] Example 2

[0042] like Figure 1-6 As shown, the cleaning cover 11 is hinged on the cleaning box 1 and is made of glass or transparent plastic. It can be easily opened and closed to facilitate observation of the cleaning and screening process.

[0043] Clamping grooves 8 are symmetrically formed on the first mounting bracket 3 and the second mounting bracket 4 , and positioning holes 81 are formed in the clamping grooves 8 .

[0044] The filter structure 5 includes a first frame 51 and a second frame 52. There are two groups of the first frame 51 and the second frame 52. The two groups of first frames 51 are connected to each other, and the two groups of second frames 52 are connected to the outside of the two groups of first frames 51. The first frame 51 and the second frame 52 are both provided with connecting holes 53 at the corners. The connecting holes 53 are fixed by bolts to connect the first frame 51 and the second frame 52 and then installed.

[0045] The first frame 51 and the second frame 52 are both provided with a screening filter 54 at their outer ends, and the mesh size of the screening filter 54 on the second frame 52 is smaller than that of the screening filter 54 on the first frame 51;

[0046] Among them, since the outer sieve filter 54 is smaller than the sieve filter 54, large particles can be thrown out into the space between the first frame 51 and the second frame 52, and the mesh of the outer sieve filter 54 is smaller, a smaller mesh can be set to prevent large impurities or seeds from leaking out;

[0047] As mentioned above, the mesh of the inner screening filter 54 is relatively large, and the mesh may not be able to limit the rice seeds from being thrown out laterally, but the number will not be too large, so the rice seeds will not be mixed with impurities thrown into the space between the first frame 51 and the second frame 52, resulting in ineffective screening.

[0048] The two sets of first frames 51 are provided with docking blocks 55 on the outer sides corresponding to the clamping grooves 8, and threaded holes 56 are opened corresponding to the positioning holes 81. The positioning holes 81 and the threaded holes 56 are connected by bolts to fix the filter structure 5 to the first mounting bracket 3 and the second mounting bracket 4.

[0049] Electric valves 9 are installed on the water inlet pipe 6 and the water outlet pipe 7, and the bottom of the cleaning box 1 is designed in a funnel-shaped structure, and the lowest point is connected to the water outlet pipe 7. Electric valves 9 are installed on the water inlet pipe 6 and the water outlet pipe 7, which can conveniently control the inflow and outflow of water and realize automatic operation.

[0050] The second mounting bracket 4 is rotatably connected to a rotating shaft seat 10 mounted on the inner wall of the cleaning box 1 through a shaft.

[0051] The working process of the utility model is as follows: prepare the rice seeds that need to be cleaned and screened, place them in the first frame 51, connect the two sets of first frames 51 relative to each other, connect the two sets of second frames 52 to the outside of the two sets of first frames 51, fix the connecting holes 53 with bolts, the docking blocks 55 on the outside of the two sets of first frames 51 correspond to the clamping grooves 8, and ensure that the threaded holes 56 are aligned with the positioning holes 81, use bolts to fix the filter structure 5 to the first mounting bracket 3 and the second mounting bracket 4 through the threaded holes 56 and the positioning holes 81, and open the electric valve 9 on the water inlet pipe 6. , add an appropriate amount of water to the washing tank 1. If necessary, add an appropriate amount of liquid medicine to soak the rice seeds. Close the electric valve 9 on the water inlet pipe 6 and start the drive motor 2. The drive motor 2 drives the first mounting bracket 3 and the second mounting bracket 4 to rotate, thereby causing the filter structure 5 to begin rotating. Under the action of the rotation of the filter structure 5, the rice seeds and impurities are thrown up and washed by the water flow. Due to the different mesh sizes of the washing filter 54 on the first frame 51 and the second frame 52, the impurities are gradually screened out. After cleaning is completed, turn off the drive motor 2. Open the electric valve 9 on the outlet pipe 7, and the water in the washing tank 1 will be discharged through the outlet pipe 7. Remove the filter structure 5 or repeat different hydraulic treatments.

[0052] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
