DETAILED DESCRIPTION

[0018] The specific embodiments of the application are further described in detail below with reference to the drawings, and the description of the embodiments helps the person skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical scheme of the application.

[0019] As Figures 1-6As shown in the figure, the present invention provides a vibrating sieve device for paddy rice, including a sieve box 1 and a vibrating sieve mechanism 4. The top of the sieve box 1 is provided with a feed hole, and a feed hopper 13 is provided at the feed hole of the sieve box 1. Through the provided feed hopper 13, it is more convenient to pour paddy rice into the sieve basket 3. At the opening 11 on one side of the sieve box 1, a door 12 is hinged through a hinge, and the door 12 is connected to the sieve box 1 through an industrial buckle two 14. Through the provided industrial buckle two 14, it is more convenient to open and close the door 12. A limiting frame 2 is slidably connected in the sieve box 1. Above the spring 21 in the limiting frame 2, there is a sieve basket 3. One side of the limiting frame 2 is hinged with a limiting plate 22 through a hinge, and the limiting plate 22 is connected to the limiting frame 2 through an industrial buckle one 23. The vibrating sieve mechanism 4 is arranged in the sieve box 1 and is used to vibrate the paddy rice in the sieve basket 3 up and down and left and right, so as to separate impurities from the paddy rice.

[0020] It should be noted that the vibrating sieve mechanism 4 includes a motor 46, a rotating shaft 42 and a driving plate 41. The driving plate 41 is arranged at the bottom of the limiting frame 2 and has a "return" - shaped driving groove 411 on it. The rotating shaft 42 is rotatably connected to the sieve box 1 and the mounting frame 43 in the sieve box 1. A number of cams 44 for driving the sieve basket 3 are arranged on the rotating shaft 42. A plug rod 45 inserted into the driving groove 411 is arranged on the side of one of the cams 44. The motor 46 is fixed to the side of the sieve box 1 through a mounting plate 461, and a pulley one 462 is installed on its output shaft. The pulley one 462 is connected to a pulley two 48 on the rotating shaft 42 through a driving belt 47. The sieve basket 3 is driven to move up and down by the cam 44, and at the same time, the sieve basket 3 is driven to move left and right by the driving plate 41, so that the sieve basket 3 can move in multiple directions simultaneously, and the paddy rice in the sieve basket 3 can be vibrated more thoroughly.

[0021] In addition, a slag - receiving box 5 is arranged in the sieve box 1 to facilitate the collection of impurities sifted from the sieve basket 3.

[0022] Specific implementation method and principle:

[0023] In actual application, the motor 46 is turned on, and the rice to be screened is poured into the sieve basket 3 from the feeding hopper 13 on the top of the sieve box 1, the belt pulley one 462 on the output shaft of the motor 46 drives the belt pulley two 48 and the rotating shaft 42 to rotate through the driving belt 47, the rotating shaft 42 drives the cam 44 on it to rotate, the convex part of the cam 44 lifts the sieve basket 3 on the limiting frame 2, when the cam 44 is out of contact with the sieve basket 3, under the action of gravity, the sieve basket 3 moves downward, at the same time, the inserting rod 45 on the side of the cam 44 moves in the driving groove 411 on the driving plate 41, thereby driving the limiting frame 2 and the sieve basket 3 to move left and right in the sieve box 1, so that the rice in the sieve basket 3 can be more fully screened, and the impurities and the rice are separated more thoroughly, when the screening of the rice is completed, the box door 12 is opened through the industrial buckle two 14, then the industrial buckle one 23 on the limiting frame 2 is opened, and the limiting plate 22 is rotated, the sieve basket 3 containing the screened rice is taken off from the spring 21 of the limiting frame 2, and finally the screened rice in the sieve basket 3 is poured into the collecting device.

[0024] The above is an exemplary description of the present application in combination with the drawings, and it is obvious that the specific implementation of the present application is not limited by the above method, as long as various non-essential improvements are made by adopting the concept and technical solution of the present application, or the present application and the technical solution are directly applied to other occasions without improvement, which are all within the protection scope of the present application.
