[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Reference Figure 1 , Figure 3 , Figure 4, the utility model provides an embodiment: a seed screening device for mat grass planting, comprising a box body 1 and a fixed plate 4, a feed hopper 3 is fixedly connected to the top right side of the box body 1, a filter plate 10 is fixedly connected to the lower inner side of the box body 1, and a mounting shell 15 is fixedly connected to the left and right sides of the bottom of the filter plate 10, one end of the mounting shell 15 is fixedly connected to a motor 11, and a threaded rod 16 is fixedly connected to the output end of the motor 11, and a threaded block 17 is threadedly connected to the outer side of the threaded rod 16, and a mounting plate 18 is fixedly connected to one end of the threaded block 17, and a brush 19 is arranged on the outside of the mounting plate 18, a waste box 12 is slidably connected to the inner bottom wall of the box body 1, and a dust removal assembly is installed on the top of the fixed plate 4, a sliding column 21 is fixedly connected to the inside of the right mounting shell 15, and a connecting block 20 is slidably connected to the outer side of the sliding column 21, and one end of the connecting block 20 is fixedly connected to the outer side of the mounting plate 18.
[0031] Specifically, the function of the filter plate 10 is to enable seeds to be quickly and effectively classified when passing through the filter plate 10. Qualified seeds can be smoothly discharged from one end of the filter plate 10, while unqualified seeds will be intercepted and fall into the waste bin 12 below through the holes of the filter plate 10. This efficient screening process not only reduces manual operation, but also improves the efficiency of the entire screening process. Driven by the motor 11, the threaded rod 16 can rotate, thereby driving the threaded block 17 and the brush 19 on the mounting plate 18 to move up and down. This automated cleaning method greatly reduces the need for manual operation, improves cleaning efficiency, and reduces labor intensity. Through the sliding connection between the sliding column 21 and the connecting block 20, the mounting plate 18 can obtain more stable support when moving up and down. This design reduces the possibility of shaking or offsetting of the mounting plate 18 due to vibration or other external forces, thereby ensuring that the brush 19 can stably and accurately clean the residue on the filter plate 10.
[0032] Reference Figure 1 , Figure 2 , Figure 3 The dust removal component includes an air pump 6, the outside of the air pump 6 is fixedly connected to the top side of the fixed plate 4, the input end of the air pump 6 is fixedly connected to a dust suction pipe 5, one end of the dust suction pipe 5 is fixedly connected to a dust collecting hood 14, the top side of the fixed plate 4 is fixedly connected to a dust removal box 8, the left side of the dust removal box 8 is fixedly connected to a connecting pipe 9, the right side of the dust removal box 8 is fixedly connected to a connecting pipe 7, one end of the connecting pipe 7 is fixedly connected to the output end of the air pump 6, and a filter is arranged inside the dust removal box 8.
[0033] Specifically, a large amount of dust will be generated when the seeds enter the interior of the box 1. At this time, the air pump 6 is started, and the air pump 6 generates suction to suck the dust into the dust box 8 through the dust suction pipe 5 and the dust collecting hood 14. The filter screen in the dust box 8 filters and collects the dust, and the clean air is discharged through the connecting pipe 9, which effectively reduces the dust pollution in the working environment and improves the work efficiency and comfort of the operators. The main function of the filter screen in the dust box 8 is to filter out the dust particles in the airflow passing through the dust box 8. This helps to ensure that the air discharged from the dust box 8 is relatively clean, thereby preventing the dust from being released back into the working environment and further protecting the health of the operators.
[0034] Reference Figure 1 , Figure 2 , Figure 4 A handle 13 is fixedly connected to the outside of the waste box 12, and the outside of the handle 13 is provided with anti-slip grooves. The brush 19 is made of flexible material, and the outside of the brush 19 fits the outer surface of the filter plate 10. Support legs 2 are fixedly connected to the four corners of the bottom of the box body 1, and the bottom of the support legs 2 is provided with anti-slip grooves.
[0035] Specifically, the waste box 12 is used to collect waste generated during the screening process, such as unqualified seeds or other impurities. The provision of the handle 13 enables the operator to easily move the waste box 12, which is convenient for cleaning and replacement. The anti-skid pattern design on the outside of the handle 13 increases the friction when holding, preventing accidents caused by hand slippage. The outside of the brush 19 fits the outer surface of the filter plate 10, which can ensure that the filter plate 10 is fully and effectively cleaned, and residual shriveled seeds and other debris are removed, so as to maintain the smooth flow and screening effect of the filter plate 10. The support leg 2 ensures the stability of the entire screening device, and prevents failures or accidents caused by shaking or tilting of the equipment during operation. The anti-skid pattern design at the bottom of the support leg 2 increases the friction between the equipment and the ground, preventing the equipment from sliding due to wet ground or other reasons, and ensuring the stability and safety of the equipment.
[0036] Working principle: The user pours the mat grass seeds to be screened into the box body 1 through the feed hopper 3. The seeds fall naturally under the action of gravity and enter the internal space of the box body 1. When a large amount of dust attached to the surface of the seeds enters the interior of the box body 1, a large amount of dust will be generated. At this time, the air pump 6 is started. When the air pump 6 is started, suction will be generated, and the dust will be sucked in through the dust suction pipe 5 and the dust hood 14. The inhaled dust will enter the dust removal box 8. A filter screen is provided inside the dust removal box 8 for filtering and collecting dust. The filtered clean air is discharged through the connecting pipe 9, and the dust is trapped on the filter screen. It can reduce the spread of dust, keep the working environment clean, and improve the work efficiency and comfort of the operator.
[0037] During the falling process, the seeds will encounter the filter plate 10 fixed inside the housing 1. Qualified seeds will be discharged from one end of the filter plate 10 because the filter plate 10 is set at an angle. Unqualified seeds, such as seeds that are too small, too large or do not meet the weight standard, will fall into the waste bin 12 below through the holes of the filter plate 10. At the same time, the motor 11 and the external device are started to drive the device to vibrate, and the motor 11 drives the threaded rod 16 connected to its output end to rotate. When the threaded rod 16 rotates, the threaded block 17 moves up and down along the axial direction of the threaded rod 16. As the threaded block 17 moves up and down, the mounting plate 18 and the brush 19 will also move up and down synchronously. Since the outer part of the brush 19 is tightly fitted with the outer surface of the filter plate 10, when the brush 19 moves up and down, it can effectively prevent the shrunken seeds and other debris from getting stuck in the filter holes on the filter plate 10, thereby maintaining the smooth flow and screening effect of the filter plate 10.
[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
