Description

Technical Field

[0001] This utility model relates to the field of rice breeding technology, specifically a screening device for rice breeding. Background Technology

[0002] Rice is an important food crop in my country. Through hybrid rice breeding, hybrid rice varieties with high yield potential can be cultivated. In order to achieve high rice yield, in addition to good varieties, precise paddy field management is also crucial. In the process of planting rice, it is necessary to remove impurities from the seeds to ensure that the seeds are pure and intact. This plays an important role in improving the germination rate and reducing pests and diseases.

[0003] According to a rice seed screening and impurity removal device (Announcement No.: CN220738451U) disclosed in the above application, the rice seeds that need to be screened and impurity removed are brought into the impurity removal box. Then, the staff controls the vibrator to work through the control switch. The screening box and the impurity removal box in the screening frame vibrate. After the rice seeds pass through the impurity removal box and large particles of impurities are screened off by simple vibration, they fall onto the upper screen. Small particles of rice seeds are vibrated and screened again and fall onto the lower screen. The impurity screening can be completed in steps, making the screening more thorough. Multi-stage screening makes the sorting of rice seeds more precise.

[0004] However, in actual use, although the above-mentioned equipment can perform multi-layer screening to obtain seeds of different sizes, when the screening box is vibrated, many vibrating seeds cannot be evenly spread on the screening box, thus the screening rate cannot be maximized; in view of this, we propose a screening device for rice breeding. Utility Model Content

[0005] The purpose of this invention is to provide a screening device for rice breeding to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a screening device for rice breeding, comprising a body, a collection chamber detachably installed on the outer wall of the body, an elastic telescopic plate fixedly connected to the outer wall of the body, a snap-fit ​​assembly fixedly connected to the end of the elastic telescopic plate, a screening frame detachably installed on the outer wall of the snap-fit ​​assembly, a spreading assembly provided on the outer wall of the screening frame, the spreading assembly including a guide groove, the guide groove being formed on the outer wall of the screening frame, an arc-shaped protrusion fixedly connected to the outer wall of the screening frame, a vibrator fixedly connected to the outer wall of the screening frame, a motor fixedly connected to the outer wall of the screening frame, a reciprocating threaded rod fixedly connected to the output end of the motor through the screening frame, a threaded slider threadedly connected to the outer wall of the reciprocating threaded rod, a fixing plate fixedly connected to the outer wall of the threaded slider, and a flexible swing rod fixedly connected to the outer wall of the fixing plate;

[0007] The mounting plate is fixedly connected to the end of the flexible rocker arm. The outer wall of the mounting plate is fixedly connected to bristles. The outer wall of the threaded slider is fixedly connected to a fixing sleeve. The inner wall of the fixing sleeve is slidably connected to a sliding block. The outer wall of the sliding block is fixedly connected to a sliding head. The outer wall of the sliding block is fixedly connected to a lifting plate. The outer wall of the lifting plate is fixedly connected to a poking plate. The end of the poking plate is fixedly connected to a pressing head.

[0008] Preferably, the outer wall of the sliding head is slidably connected to the inner wall of the guide groove, and the guide groove is wavy, so that the sliding head can move smoothly on the inner wall of the guide groove.

[0009] Preferably, the number of arc-shaped protrusions is several, and the several arc-shaped protrusions are arranged in a linear array on the outer wall of the screening frame, so that the arc-shaped protrusions can periodically squeeze and actuate the flexible swing rod, thereby enabling the flexible swing rod to swing when it is displaced.

[0010] Preferably, the center line of the lifting plate, the center line of the shovel plate, and the center line of the pressure head are all in the same plane.

[0011] Preferably, the outer wall of the mounting plate is provided with a triggering component, the triggering component includes a beveled groove, the beveled groove is formed on the outer wall of the mounting plate, a movable arc strip is fixedly connected to the outer wall of the mounting plate, and a triggering arc strip is fixedly connected to the outer wall of the pressing head.

[0012] Preferably, the outer wall of the activated arc strip is adapted to the outer wall of the activated arc strip.

[0013] Compared with the prior art, this utility model provides a screening device for rice breeding, which has the following beneficial effects:

[0014] 1. In this rice breeding screening equipment, the motor drives a reciprocating threaded rod to rotate, which in turn causes the limited threaded slider to move the fixed plate. This allows the bristles under the flexible swing arm to smooth the seeds that have accumulated due to vibration. When the flexible swing arm moves, it is touched by the arc-shaped protrusion, causing the flexible swing arm to swing, thus better smoothing the accumulated seeds and enabling effective screening of a large number of seeds. When the threaded slider moves the fixed plate, the sliding head can move smoothly on the inner wall of the guide groove. Through the transmission of the chuck plate, the pressing head periodically touches the mounting plate, ultimately allowing the seeds attached to the bristles to be smoothly removed. This ensures that the bristles can evenly spread the seed material while also performing self-cleaning.

[0015] 2. This rice breeding screening equipment allows the sliding head to move smoothly on the inner wall of the guide groove. Through the transmission of the chuck plate, the pressing head periodically touches the mounting plate. The set driven and activated arc strips cause the pressing head to move along the inclined groove, resulting in mutual rubbing between the driven and activated arc strips. This vibration further enhances the tactile effect of the bristles and allows the seeds adhering to the bristles to fall off more effectively, thus improving the overall practicality.

[0025] like Figures 1-8As shown, this utility model provides a technical solution: a screening device for rice breeding, including a body 1, a collection chamber 2 detachably installed on the outer wall of the body 1, an elastic telescopic plate 4 fixedly connected to the outer wall of the body 1, a buckle assembly 5 fixedly connected to the end of the elastic telescopic plate 4, a screening frame 6 detachably installed on the outer wall of the buckle assembly 5, a spreading assembly 7 provided on the outer wall of the screening frame 6, the spreading assembly 7 including a guide groove 701, the guide groove 701 being opened on the outer wall of the screening frame 6, an arc-shaped protrusion 702 fixedly connected to the outer wall of the screening frame 6, a vibrator 703 fixedly connected to the outer wall of the screening frame 6, a motor 704 fixedly connected to the outer wall of the screening frame 6, a reciprocating threaded rod 705 fixedly connected to the output end of the motor 704 through the screening frame 6, a threaded slider 706 threadedly connected to the outer wall of the reciprocating threaded rod 705, a fixing plate 707 fixedly connected to the outer wall of the threaded slider 706, and a flexible swing rod 708 fixedly connected to the outer wall of the fixing plate 707.

[0026] Furthermore, the mounting plate 709 is fixedly connected to the end of the flexible rocker arm 708. The outer wall of the mounting plate 709 is fixedly connected to the bristles 710. The outer wall of the threaded slider 706 is fixedly connected to the fixing sleeve 711. The inner wall of the fixing sleeve 711 is slidably connected to the sliding block 712. The outer wall of the sliding block 712 is fixedly connected to the sliding head 713. The outer wall of the sliding block 712 is fixedly connected to the lifting plate 714. The outer wall of the lifting plate 714 is fixedly connected to the poking plate 715. The end of the poking plate 715 is fixedly connected to the pressing head 716.

[0027] In this embodiment of the present invention, the outer wall of the sliding head 713 is slidably connected to the inner wall of the guide groove 701, and the guide groove 701 is set in a wave shape, so that the sliding head 713 can move smoothly on the inner wall of the guide groove 701. The number of arc-shaped protrusions 702 is several, and the several arc-shaped protrusions 702 are arranged in a linear array on the outer wall of the screening frame 6, so that the arc-shaped protrusions 702 can periodically press and actuate the flexible swing rod 708, thereby making the flexible swing rod 708 swing when it moves. The center line of the lifting plate 714, the center line of the punch plate 715, and the center line of the pressing head 716 are all in the same plane.

[0028] Furthermore, the outer wall of the mounting plate 709 is provided with a triggering component 8, which includes a beveled groove 801. The beveled groove 801 is formed on the outer wall of the mounting plate 709. A movable arc strip 802 is fixedly connected to the outer wall of the mounting plate 709, and a triggering arc strip 803 is fixedly connected to the outer wall of the pressing head 716. The outer wall of the movable arc strip 802 is adapted to the outer wall of the triggering arc strip 803.

[0029] In this invention, during daily use, the screening frames 6 are installed sequentially from top to bottom, with the largest opening decreasing in size. Rice seeds are then placed on the top layer, and the motor 704 and vibrator 703 are started for screening. While the vibrator 703 drives the screening frames 6 to vibrate and screen, the motor 704 drives the reciprocating threaded rod 705 to rotate. This causes the limited threaded slider 706 to move the fixed plate 707, allowing the bristles 710 under the flexible swing rod 708 to evenly distribute the seeds accumulated by vibration. Furthermore, as the flexible swing rod 708 moves, it... When the curved protrusion 702 is activated, the flexible swing arm 708 can swing during displacement, thereby better smoothing the accumulated seeds and enabling effective sieving of a large number of seeds. When the threaded slider 706 drives the fixed plate 707 to move, the sliding head 713 can move smoothly on the inner wall of the guide groove 701. Then, through the transmission of the poker plate 715, the pressing head 716 periodically touches the mounting plate 709, ultimately allowing the seeds attached to the bristles 710 to be smoothly removed, ensuring that the bristles 710 can evenly spread the seed material while performing self-cleaning.

[0030] When the sliding head 713 can move smoothly on the inner wall of the guide groove 701, and the contact head 716 periodically touches the mounting plate 709 through the transmission of the poker plate 715, the contact head 716 will move along the inclined groove 801 through the set driven arc strip 802 and the contact arc strip 803. This causes the driven arc strip 802 and the contact arc strip 803 to rub against each other, and the vibration further enhances the touching effect of the bristles 710, and allows the seed material attached to the bristles 710 to fall off better, thereby further improving the overall practicality.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
