[0022] The vibrating screening mechanism can be used to screen the rice seeds, and the seeds with smaller and less full grains and small foreign objects can be screened out. The rice seeds are spread under the action of the vibrating screening mechanism, and the dust and smaller husks on the rice seeds are sucked away by the exhaust mechanism. Water is injected into the screening box 14 through the water inlet pipe 12, and the rice seeds that have been vibrated and screened are stirred by the stirring component so that the large and full rice seeds that meet the requirements are fully immersed in water and sink to the bottom of the screening box 14. Husks and less full rice seeds float on the water surface, and the floating objects are intercepted and isolated by the husk intercepting component, so that the husks and less full seeds can be effectively sorted, and the full seeds are dried by the drying device for easy storage.

[0023] Furthermore, the exhaust mechanism includes an exhaust hood 3 connected to the inner wall of the shell 1 , the exhaust hood 3 is trumpet-shaped, the exhaust hood 3 is arranged corresponding to the vibration screening mechanism, and an exhaust fan 4 is arranged in the exhaust hood 3 .

[0024] The exhaust hood 3 is arranged above the entire spread seeds, so that floating dust and smaller husks can be effectively sucked and discharged outside the shell 1.

[0025] Furthermore, the vibration screening mechanism includes a bracket 5 fixedly connected to the side wall of the shell 1, one end of a screen plate 6 is hinged on the bracket 5, the screen plate 6 is tilted, a vibration motor 10 is provided in the middle of the bottom surface of the screen plate 6, a cross plate 8 is provided below the screen plate 6, one end of the cross plate 8 is connected to the inner wall of the shell 1, and the other end of the cross plate 8 is elastically connected to the lowest end of the screen plate 6 through a spring 7, a material box 9 for collecting small seeds is placed on the top of the cross plate 8, and a side opening 11 is opened on the side wall of the shell 1, and the side opening 11 is used for taking out and placing the material box 9 and for ventilation.

[0026] The rice seeds slide down from the highest end of the screen plate 6 to achieve spreading. The screen plate 6 swings along the hinge shaft under the action of the spring 7 and the vibration motor 10 to achieve the screening of the rice seeds. Small seeds and foreign objects pass through the holes on the screen plate 6 and fall into the material box 9 for collection.

[0027] Furthermore, the stirring assembly includes a motor 22 installed in the middle of the bottom end of the screening box 14. The output end of the motor 22 passes through the screening box 14 and is connected to a plurality of stirring blades 23. The plurality of stirring blades 23 are arranged at equal intervals along the outer wall of the output shaft of the motor 22.

[0028] The stirring blades 23 are driven to rotate by the motor 22, thereby stirring the rice seeds, accelerating the soaking of the full seeds in the water bottom, and floating the unfull seeds and husks to the water surface, thereby improving the efficiency of sorting.

[0029] Furthermore, the chaff interception assembly includes two baffles 15 obliquely arranged on the inner wall of the opening of the screening box 14, and the two baffles 15 are arranged in an inverted eight shape. A steering gear 17 is installed in the middle of one side of the screening box 14, and the output shaft of the steering gear 17 is connected to one end of a swing arm 18, and the other end of the swing arm 18 is vertically connected to a support rod 30, and one side of an interception net 19 is connected to the support rod 30, and the other side of the interception net 19 is fixedly connected to a baffle 15, and the support rod 30 is in friction contact with the baffle 15, and the interception net 19 is immersed in water.

[0030] When all the husks and unfilled seeds float on the water surface, start the steering gear 17 to drive the swing arm 18 to rotate, and the swing arm 18 drives the support rod 30 to rotate. The support rod 30 pulls the interception net 19 to expand and cover the inverted eight-shaped shape surrounded by the two baffles 15, so as to effectively isolate the floating objects on the water from the full seeds on the bottom of the water. A discharge pipe 20 is connected to the bottom of the screening box 14, and a solenoid valve 21 is provided on the discharge pipe 20. When it is necessary to discharge the full seeds, only the solenoid valve 21 needs to be opened, and the full seeds are discharged from the screening box 14 together with the water and enter the drying device, and are accumulated on the conveyor belt of the conveyor 26 for drainage. The floating objects finally fall on the interception net 19 as the water level in the screening box 14 drops.

[0031] Furthermore, in order to allow the seeds that have been vibrated and screened to enter the screening box 14 smoothly, a guide plate 16 is provided on one side of the shell 1 close to the lowest end of the screen plate 6 , and the guide plate 16 is used to guide the seeds that have been vibrated and screened into the screening box 14 .

[0032] Furthermore, it also includes a conveyor 26, which is arranged below the discharge port, and the drying device is arranged on the conveyor 26.

A plurality of ventilation holes are opened on the conveyor belt surface of the conveyor 26, and the aperture of the ventilation holes is smaller than the particle size of the rice seeds.

[0034] In this embodiment, the conveyor 26 and the drying fan 25 are commercially available parts, which are prior art. Air holes are punched on the conveyor belt of the conveyor 26. In order for the hot air blown out by the drying fan 25 at the bottom to pass through the conveyor belt and act on the plump seeds to accelerate the evaporation of surface moisture, it is necessary to control the temperature of the hot air blown out by the drying fan 25 to avoid damaging the seeds. A plurality of drain pipes 27 are arranged at the bottom of the drying hood 24, and a water collecting box 28 is placed directly under the drain pipe 27 to collect the drained water. A collecting box 29 is placed at the other end of the conveyor 26 to facilitate the collection of the plump seeds after drying.

[0035] The present invention provides a rice seed processing and selection machine, and its working principle is as follows: when in use, the rice seeds to be selected enter from the feed hopper 2, and the rice seeds slide down from the highest end of the screen plate 6 to achieve spreading. The screen plate 6 swings up and down along the hinge axis under the action of the spring 7 and the vibration motor 10, and small seeds and foreign matter pass through the screen plate 6 and fall into the material box 9 for collection, thereby achieving the screening of the rice seeds. At the same time, the floating dust and smaller husks on the rice seeds are discharged through the exhaust mechanism, and then the seeds that have been preliminarily screened enter the screening box 14 under the guidance of the guide plate 16. After a certain amount of rice seeds are accumulated in the screening box 14, the rice seeds are stopped from being poured into the feed hopper 2, and water is started to be injected into the screening box 14. When the water surface submerges the intercepting net 19, the water injection is stopped. At this time, the intercepting net 19 is in a retracted state, and the motor 22 is turned on, and the motor 22 drives the stirring blade 23 to rotate. Then, the rice seeds are stirred to accelerate the soaking of the full seeds in the water bottom, and the unfull seeds and husks float to the water surface. When the husks and unfull seeds all float to the water surface, the steering gear 17 is turned on, and the steering gear 17 drives the swing arm 18 to rotate, and the swing arm 18 drives the support rod 30 to rotate, and the support rod 30 pulls the interception net 19 to expand and cover the inverted eight-shaped mouth surrounded by the two baffles 15, and then the solenoid valve 21 is opened, and the full seeds are discharged to the conveyor 26 with the water for drainage, and the floating objects finally fall on the interception net 19 as the water level in the screening box 14 drops. When the drainage is completed, the drying fan 25 and the conveyor 26 are turned on to dry the full seeds. It should be noted that in order to improve the drying effect, a baffle is provided at one end of the conveyor 26 close to the discharge pipe 20, and the full seeds pass through the distance between the baffle and the conveyor belt surface, thereby controlling the paving thickness of the full seeds.
