Technical Field
[0001] The utility model belongs to the technical field of seed impurity removal, and specifically relates to an integrated device for seed impurity removal and cleaning. Background Art
[0002] Seed impurity removal is a key link in the agricultural production process and is of great significance for improving seed quality and promoting crop growth. Currently, seed impurity removal mainly relies on traditional manual screening and mechanical screening methods. Although manual screening has high precision, it is inefficient, costly, and labor-intensive. Although mechanical screening methods have improved the processing efficiency, the planting survival rate of seeds is not high because there are still problems such as insufficient precision and seed damage during the impurity removal process, resulting in the collected seeds being mixed with hollow, damaged, and inferior seeds and impurities. Therefore, the harvested seeds need to be impurity-removed, which is to remove the hollow husks and impurities mixed in the seeds to improve the seed germination rate. During the traditional vibration screening impurity removal process, due to the small size of the seeds, they will pile up when falling down, and it is impossible to remove the doped hollow husks and immature and plump seeds. Moreover, only using vibration impurity removal cannot completely remove fine dust and surface attachments, and the situation of incomplete seed impurity removal will occur. Therefore, in order to better remove the hollow and inferior seeds mixed in the seeds and carry out deeper cleaning, it is necessary to develop an integrated device that can screen out large-particle impurities and fine sand while cleaning, improve work efficiency, enhance the impurity removal effect, and remove hollow and inferior seeds and fine impurities attached to the seeds. Content of the Utility Model
[0003] In view of the above technical problems, the utility model provides an integrated device that can screen out large-particle impurities and fine sand while cleaning, improve work efficiency, enhance the impurity removal effect, and remove hollow and inferior seeds and fine impurities attached to the seeds.
[0004] To solve the above technical problems, the utility model relates to an integrated device for seed impurity removal and cleaning, which includes a water tank. A screening box and a cleaning box are fixedly connected to the water tank, and universal wheels are fixedly connected to the bottom. An inlet is provided at the top of the screening box, and a first vibrating screen and a second vibrating screen are obliquely arranged inside, and their inclined directions are opposite. The second vibrating screen is located below the first vibrating screen. Springs are connected to the bottoms on both sides of the first vibrating screen and the second vibrating screen and are connected to bosses, and the bosses are fixedly connected to the inside of the screening box. The downward inclined end of the first vibrating screen extends through a first strip-shaped hole to the outside of the screening box, and the downward inclined end of the second vibrating screen extends through a second strip-shaped hole to above the cleaning box. A plurality of water inlets penetrating the side wall are fixedly connected to the left side of the cleaning box, and the water inlets are communicated with a water pump through a water pipe. The input end of the water pump is communicated with the water tank through a water supply pipe. A diversion trough is connected to the right side of the cleaning box, and the diversion trough is fixedly connected to a filter barrel. A filter screen and an activated carbon layer are detachably connected from top to bottom inside the filter barrel, and the lower end is communicated with the water tank.
[0005] Further, an observation port is arranged on the outer surface of the water tank, and a water outlet is arranged at the bottom of one side. The water pump is fixedly connected to the water tank.
[0006] Further, a drawer is slidably connected to the lower part of the screening box.
[0007] Further, the aperture of the first vibrating screen is larger than that of the second vibrating screen.
[0008] Further, a filter basket is movably placed inside the cleaning box, and the upper edge of the filter basket is flush with the lower edge of the diversion trough.
[0009] Further, a plurality of strip-shaped protrusions are arranged on the upper surfaces of the first vibrating screen and the second vibrating screen.
[0010] The utility model has the following advantages compared with the prior art:
[0011] 1. The utility model can separate different impurities from seeds and conduct in-depth cleaning by setting a screening box and a cleaning box, enabling the seeds to pass through two sieves with different pore sizes, thereby improving the impurity removal effect. By fixedly connecting a number of water inlets penetrating the side wall on the left side of the cleaning box, the inferior seeds and fine impurities floating on the water surface can be washed to the right side and flow out of the cleaning box through the water flow for automatic impurity removal. By connecting the water pump input end to the water tank through a water supply pipe, the water in the water tank can be pumped out for water selection treatment. By connecting a diversion trough on the right side of the cleaning box, the diversion trough is fixedly connected to a filtering barrel, and a filter screen and an activated carbon layer are detachably connected from top to bottom in the filtering barrel, enabling the diversion trough to separate water and impurities when guiding the outflowing water and further filtering the water by using the activated carbon layer. By connecting the bottom of the diversion trough to the water tank, the cleaning box can be connected to the water tank to enable the reuse of water and reduce the waste of water resources.
[0012] 2. By setting an observation port on the outer side of the water tank, it is convenient to observe the water level and water quality of the water tank, and timely replenish water and replace it when necessary. By setting a water outlet at the bottom of one side of the water tank, it is convenient to replace the water in the water tank.
[0013] 3. By slidably connecting a drawer to the lower part of the screening box, the fine sand grains and dust mixed in the seeds can be collected together during the screening process, avoiding the reduction of the impurity removal effect caused by the flying dust.
[0014] 4. By setting two vibrating sieves with different pore sizes, the seeds can smoothly pass through the first vibrating sieve to screen out large impurities.
[0015] 5. By movably placing a filter basket inside the cleaning box, it is convenient to salvage and collect the seeds after cleaning and screening.
[0016] 6. By setting a number of strip-shaped protrusions on the surface of the vibrating sieve, the falling speed of the seeds can be slowed down, facilitating the full screening of the seeds. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present utility model will be further described below in conjunction with the accompanying drawings.
[0023] As Figures 1 to 4 shown, a seed impurity removal and cleaning integrated device includes a water tank 1. In order to realize the impurity removal and cleaning integrated device, a screening box 2 and a cleaning box 13 are fixedly connected to the water tank 1. In order to facilitate the movement of the device, universal wheels 21 are fixedly connected to the bottom of the water tank 1. The top of the screening box 2 is provided with a feeding port 3, and a first vibrating screen 4 and a second vibrating screen 8 are inclined inside, and the inclination directions of the two are opposite. The second vibrating screen 8 is located below the first vibrating screen 4. The bottoms of both sides of the first vibrating screen 4 and the second vibrating screen 8 are connected to the boss 6 through springs, and the boss 6 is fixedly connected to the inside of the screening box 2. In order to facilitate the separation of the screened impurities, the seeds fall into the cleaning box 13. The inclined downward end of the first vibrating screen 4 extends through the first strip-shaped hole 22 to the outside of the screening box 2, and the inclined downward end of the second vibrating screen 8 extends through the second strip-shaped hole 9 to above the cleaning box 13. In order to enable the water to flow evenly to the right, 8 equally spaced water inlets 18 penetrating the side wall are fixedly connected to the left side of the cleaning box 13, and the water inlets 18 are connected to the water pump 11 through a water pipe. In order to pump the water in the water tank 1 to supply water to the cleaning box 13, the input end of the water pump 11 is connected to the water tank 1 through a water supply pipe 12, and the water pump 11 is fixedly connected to the water tank 1. In order to avoid wasting water resources and reuse them, the right side of the cleaning box 13 is connected to a flow guide groove 15, and the flow guide groove 15 is fixedly connected to a filter barrel 24. A filter screen 16 and an activated carbon layer 17 are detachably connected from top to bottom in the filter barrel 24, and the lower end is connected to the water tank 1.
[0024] In order to facilitate observing the water level and water quality in the water tank 1, an observation port 19 is arranged on the outer surface of the water tank 1. In order to facilitate the replacement of the water in the water tank 1, a water outlet 20 is arranged at the bottom of one side of the water tank 1.
[0025] In order to facilitate the collection of fine sand grains and dust mixed in the seeds during the screening process, a drawer 10 is slidably connected to the bottom of the screening box 2.
[0026] In order to effectively screen and separate large and small impurities, the aperture of the first vibrating screen 4 is set larger than the aperture of the second vibrating screen 8 to separate large impurities, and the seeds pass through the first vibrating screen 4 and fall onto the second vibrating screen 8.
[0027] In order to facilitate the removal of impurities and cleaned seeds from the cleaning box 13 , a filter basket 14 is movably placed inside the cleaning box 13 , and the upper edge of the filter basket 14 is flush with the lower edge of the guide groove 15 .
[0028] In order to make the screening more complete, a number of equidistant strip protrusions 7 are arranged on the surface of the vibrating screen to block the falling speed of the seeds during the screening process.
[0029] The specific working process of the utility model is as follows:
[0030] When it is necessary to remove impurities and clean the seeds, first start the water pump 11 to fill the cleaning box 13 with water. At this time, start the first vibration motor 5 and the second vibration motor 23. At the same time, put the seeds with impurities into the feed port 3. The first vibration motor 5 drives the first vibration screen 4 to vibrate, and the seeds fall from the aperture into the second vibration screen 8. Large particles of impurities are separated outward along the first vibration screen 4 through the first strip holes 22. At the same time, the second vibration screen 8 vibrates, and the seeds flow out along the second vibration screen 8 through the second strip holes 9 and fall into the cleaning box 13. Fine dust and sand fall into the bottom drawer 10. Clean them on time. When the seeds fall into the water surface, high-quality seeds fall to the bottom, and empty shells, Poor quality seeds and other impurities float on the water surface. Due to the uniform and slow flow of water flowing into the water inlet 18, the impurities and seeds floating on the water surface flow through the guide groove 15 into the filter barrel 24 along with the water flow. The impurities are separated by the filter mesh 16 and cleaned regularly. The water flows through the activated carbon layer 17 and then flows into the water tank 1 for reuse. When the cleaning is completed, the filter basket 14 is pulled upward to take out the seeds together. The water level and water quality of the water tank 1 are observed through the observation port 19 and replaced when necessary. The seeds are cleaned and removed according to the above steps, which can remove impurities more thoroughly, improve work efficiency, and avoid waste of water resources.
