Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a water-absorbing resin screening device for agricultural seed cultivation. Background Technology

[0002] Agricultural seeds refer to organs or tissues used in agricultural production that are capable of reproducing offspring. They are the basic materials for agricultural planting and the carriers of crop genetic information. The quality of seeds is directly related to many important agronomic traits of crops, such as yield, quality, and stress resistance.

[0003] In agricultural seed breeding, superabsorbent polymers (SAPs) play a crucial role in regulating the moisture environment around the seeds. Screening devices are essential tools for ensuring the quality and suitability of SAPs. By screening, SAPs with suitable particle size and quality can be selected for use with seeds. For example, for some larger seeds, such as corn seeds, SAPs with slightly larger particle size are required to ensure that the resin is evenly distributed around the seeds and effectively retains moisture. Screening devices can select SAPs that meet the requirements and use them together with corn seeds for sowing or seed pretreatment.

[0004] Most hygroscopic resin screening devices on the market currently use the excitation force generated by a vibrating motor to make the screen body vibrate, causing the material to jump forward on the screen surface, thereby achieving screening of materials of different particle sizes. However, this may cause the hygroscopic resin particles to jump too violently, causing some particles that should not pass through the screen holes to pass through, or causing the particles to be unevenly distributed on the screen, affecting the screening accuracy. Existing technology sets up a secondary screening device after the main screening device to screen the resin again after the initial screening. However, this makes the screen installation and disassembly process more complicated. If the position of the screen is not properly adjusted during installation, it may affect its flatness and coordination with the vibration device, thus affecting the screening effect.

[0035] Working principle: First, the screen 5 is inserted into the slide groove 3 of the screen box 1 via the slider 4 using the handle 20. The locking block 11 inside the slide groove 3 is opened by the fixing block 6 of the screen 5. The locking block 11 is locked by the small spring 10, preventing the fixing block 6 from loosening. Then, the vibration motors 19 on the left and right sides of the bottom of the screen box 1 are started. Then, the water-absorbing resin is poured into the feed inlet 25. Afterward, the dust cover 26 is covered to prevent dust and impurities from entering the screen box 1. The vibration motors 19 guide the water-absorbing resin that meets the conditions through the vibration of the first screen 5 to the second screen 5. The resin that does not meet the conditions and contains impurities passes through the left side of the screen box 1. The material flows out of the outlet 22. The water-absorbing resin that meets the conditions is screened again by the screen 5 to prevent some water-absorbing resin that does not meet the conditions from passing through the screen 5 through large vibration. Finally, the material that meets the conditions flows out through the outlet 22 on the right side of the screen box 1. After screening, the screen 5 can be pushed forward by the handle 20. The second slider 7 pushes against the locking block 11 to make it move on both sides to lock the second slider 7. Pull out the screen 5 so that the second slider 7 slides to the upper limit of the first fixed block 6. The arc of the second slider 7 makes the space of the locking block 11 larger, so the screen 5 can be pulled out. Then the locking block 11 returns to its original position by the small spring 10.

[0036] During the screening process, when the absorbent resin clogs the screen 5, the rotating shaft 205 at the output end of the rotating motor 201 on the outer fixed block 202 of the screen box 1 rotates. The rotating shaft 205 drives the connecting block 1 203 to rotate. The connecting block 1 203 moves back and forth in the sliding groove of the hollow connecting block 204, which drives the connecting block 206 on the outer wall to rotate. The connecting block 206 drives the tapping plate 208 in the fixed slider 207 on the inner wall of the screen box 1. The tapping plate 208 moves up and down in the fixed slider 207. The up and down movement of the tapping plate 208 helps to clear the blockage of the screen 5.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
