Description

Technical Field

[0001] The utility model relates to the technical field of rice seed processing, in particular to a rice seed impurity remover. Background Technique

[0002] At present, the traditional way for farmers to remove impurities is mostly manual screening, which is very time-consuming and laborious. There are also some mechanical rice seed impurity removal devices. A rice seed impurity remover on the market at present includes a sieve frame and a vibration device, which can vibrate and screen seeds, improving the automation level and saving labor.

[0003] However, generally only one layer of sieve mesh is set in the rice seed impurity remover, and the impurity removal is not sufficient. Moreover, when it is necessary to replace sieve meshes with different apertures, the operation is very inconvenient. For this reason, we propose a rice seed impurity remover.

The U-shaped frame body 45 is arranged inside the box body 1, and the screening box 46 is slidably connected inside the U-shaped frame body 45. The circular plate 44 is arranged at the bottom of the U-shaped frame body 45. The L-shaped plate 41 is fixedly installed on the left side of the box body 1. The motor 42 is fixedly installed inside the L-shaped plate 41, and the rotating shaft 43 is fixedly installed at the output end of the motor 42. The right end of the rotating shaft 43 penetrates the left side of the box body 1 and extends into the box body 1, and is rotatably connected with the right side inner wall of the box body 1 through a bearing one. The rotating shaft 43 is rotatably connected with the box body 1. The rotating shaft 43 penetrates through a non-central position of the circular plate 44 and is fixedly connected with the circular plate 44. Connecting the rotating shaft 43 to a non-central position of the circular plate 44 is to drive the circular plate 44 to perform an eccentric motion when rotating. The number of circular plates 44 is two, which are respectively in contact with the left and right sides of the bottom of the U-shaped frame body 45 to improve the stability of extrusion. The connecting plate 49 is fixedly installed on the inner wall of the box body 1. The L-shaped rod 410 is fixedly connected to the outer wall of the U-shaped frame body 45 and penetrates through the connecting plate 49 and is slidably connected with the connecting plate 49. The circular block 411 is fixedly connected to one end of the L-shaped rod 410. The spring 412 is sleeved on the outer wall of the L-shaped rod 410, and both ends are respectively fixedly connected to the bottom of the connecting plate 49 and the top of the circular block 411. By setting the connecting plate 49, the L-shaped rod 410, the spring 412, and the circular block 411, the U-shaped frame body 45 is stably vibrated up and down.

[0030] Embodiment 3

[0031] As Figures 2-3 shown in the figure, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the box body 1 is rotatably connected with a rotating rod 9 through a bearing two. One end of the rotating rod 9 is fixedly installed with a fan 10, and the fan 10 is located inside the box body 1. A support plate 12 is fixedly installed on the right side of the box body 1.

The rotating shaft 43 drives the circular plate 44 to perform eccentric motion, continuously squeezing the U-shaped frame 45. With the cooperation of the spring 412, the U-shaped frame 45 drives the two screening boxes 46 inside it to vibrate continuously. Then, rice seeds are poured from the feed inlet 3. The two screening boxes 46 remove impurities from the rice seeds. Large particle impurities remain inside the uppermost screening box 46, and small particle impurities fall into the interior of the box body, thereby achieving the purpose of multi-stage impurity removal for rice seeds and improving the impurity removal effect. By opening the box door 2 and starting the cylinder 5 to drive the L-shaped baffle 6 to move downward by a certain distance, the L-shaped baffle 6 is separated from the screening box 46, which facilitates the staff to pull out the screening box 46 and facilitates the staff to handle the impurities and the rice seeds after impurity removal inside the screening box 46. While starting the motor 42 to drive the screening box 46 to vibrate, through the transmission of two transmission wheels and the conveyor belt 8, the rotating rod 9 drives the fan 10 to rotate. The fan 10 rotates to generate a lateral wind force, thereby blowing the lighter impurities in the poured rice seeds into the interior of the collection box 11, achieving the purpose of preliminary impurity removal, further improving the impurity removal effect of the device, and improving the practicality of the device; the above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
