Description

Technical Field

[0001] The utility model relates to the technical field of rice breeding, in particular to a rice breeding and screening device. Background Art

[0002] In the process of rice seed processing and production, in order to improve the germination rate of rice seeds, it is necessary to carry out grading and screening operations on rice seeds of different qualities, so that the screened rice seeds of the same grade can have unified growth characteristics, which is beneficial to improving the planting yield.

[0003] During the screening process of rice seeds, a lot of impurities will be mixed inside the rice seeds. These impurities cannot be cleaned up in time and will stay above the sieve mesh and be discharged together with the seeds, affecting the seed quality.

[0004] The existing Chinese patent with the publication number CN219356525U discloses a screening device for rice variety breeding, including an equipment box body. A sieve plate is arranged inside the equipment box body. A sieve mesh is fixedly connected inside the sieve plate. Rotating shafts are fixedly connected to both the front and rear sides of the sieve plate. A positioning plate is fixedly connected to the front side of the sieve plate. A positioning chute is opened inside the positioning plate. A positioning slider is slidably connected inside the positioning chute. A rotating plate is fixedly connected to the outside of the positioning slider. An equipment shell is fixedly connected to the front side of the equipment box body. A servo motor is fixedly installed inside the equipment shell. It has the advantages of quickly removing the impurities inside the seeds, reducing the impurities inside the seeds, and improving the seed quality, and solves the problem that a lot of impurities will be mixed inside the rice seeds. These impurities cannot be cleaned up in time and will stay above the sieve mesh and be discharged together with the seeds, affecting the seed quality.

[0005] In view of the above and related existing technologies, the inventor believes that there are often the following defects: the device separates the impurities inside the seeds by injecting water, and the water cannot be recycled after carrying the impurities out, resulting in waste of water resources and needs to be improved; therefore, a rice breeding and screening device is proposed for the above problems. Content of the Utility Model

[0006] In order to make up for the deficiencies of the existing technology and solve the above-mentioned technical problems, the utility model proposes a rice breeding and screening device.

[0007] The technical solution adopted by the utility model to solve its technical problems is as follows: A rice breeding and screening device of the utility model includes a water tank, and a screening box is fixedly connected above the water tank. A sewage discharge end with a valve is installed on the lower side wall of the screening box. Brackets are fixedly connected to both sides of the screening box respectively, and an electric telescopic rod is fixedly connected to the surface of the brackets. A screening component is installed at the driving end of the electric telescopic rod. The screening component includes a sieve mesh and a separation opening. I-shaped connectors are respectively slidably connected to the four corners of the sieve mesh, and the top end of the connector is fixedly connected to the driving end of the electric telescopic rod. Buffer springs are respectively sleeved above and below the connector. A sealing chamber is fixedly connected to the center of the bottom of the sieve mesh, and a vibrator is fixedly connected inside the sealing chamber. The vibrator is waterproof-sealed through the sealing chamber. The separation opening is opened on the upper side wall of the screening box. During use, water is added to the screening box and the water tank respectively. The rice seeds are placed on the sieve mesh. The electric telescopic rod is operated to drive the sieve mesh to immerse the rice seeds in the water. The water inside the water tank is pumped by a water pump and added to the screening box. As the water level rises, impurities such as rice husks, straws, and poor-quality seeds inside the seeds will float up. Then the water flows out through the separation opening, and the floating impurities are discharged synchronously. Moreover, the vibrator drives the sieve mesh to vibrate and is buffered by the buffer springs, improving the screening speed of the rice seeds and facilitating the quick separation of the internal impurities and gravel. The gravel drops below the screening box, and the sewage discharge end is opened to discharge the gravel.

[0008] Preferably, a filter chamber is fixedly connected to the outside of the separation opening. A return pipe is fixedly connected to the bottom of the filter chamber, and the bottom end of the return pipe is connected to the water tank. When the water flows out through the separation opening, it enters the filter chamber. The impurities in the water flow are intercepted by the filter plate, and then the water flows back to the water tank through the return pipe to form a recycling, thereby reducing the waste of water resources.

[0009] Preferably, a convex layer is arranged on the inner side wall of the filter chamber, and a filter plate is placed on the convex layer. The filter plate can be taken out to clean the impurities.

[0010] Preferably, a water pump is fixedly connected to the side wall of the screening box. The liquid inlet end of the water pump is connected to the water tank through a pipeline, and the liquid outlet end of the water pump is connected to the screening box.

[0011] Preferably, a blanking component is installed on the sieve mesh. The blanking component includes two baffles, and the two baffles are symmetrically and fixedly installed on both sides of the sieve mesh. After the screening is completed, the electric telescopic rod rises to make the sieve mesh higher than the screening box. The electric sliding table is operated to push the blanking plate to slide horizontally, and then the rice seeds on the sieve mesh are pushed out of the sieve mesh and fall onto the discharge plate to be discharged, realizing the automatic blanking of the rice seeds.

[0012] Preferably, electric sliding tables are fixedly connected to the upper side walls of the two baffles respectively, and a blanking plate is fixedly connected to the bottom of the slider of the electric sliding table.

[0013] Preferably, a circulation port is formed on the surface of the blanking plate, and the circulation port corresponds to the separation port, so that water flow can pass through the circulation port and the separation port.

[0014] Preferably, an inclined discharge plate is fixedly connected to the upper side wall of the screening box.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, the vibrator drives the vibrating screen to vibrate and is buffered by the buffer spring, which improves the screening speed of rice seeds and facilitates the rapid separation of internal impurities and gravel. The water flow carries impurities such as rice husks, straws, and poor-quality seeds inside the seeds and discharges them from the separation port, while the gravel falls below the screening box, realizing the screening operation of rice seeds.

[0017] 2. In the present utility model, the electric telescopic rod rises to make the vibrating screen higher than the screening box, and the electric sliding table is moved to push the blanking plate to slide horizontally, thereby pushing the rice seeds on the vibrating screen out of the vibrating screen and falling onto the discharge plate for discharge, realizing the automatic blanking of rice seeds.
