[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the figure, the rice production and processing unloading device provided by this utility model includes a body 1, a transmission device 2 and a receiving hopper 3. The transmission device 2 is located at the front end of the body 1 and is fixedly connected to the body 1. The receiving hopper 3 is located above the rear end of the body 1 and is fixedly connected to the body 1 at its lower end. A filter flow control device 4 is provided inside the receiving hopper 3. Movable grooves 5 are opened on both the front and rear surfaces of the receiving hopper 3, and both movable grooves 5 extend into the interior of the receiving hopper 3.

[0022] refer to Figure 1 and Figure 2 The filter flow control device 4 includes a filter assembly 41, a tapping assembly 42, a linkage assembly 43, and a transmission assembly 44. The filter assembly 41 is located inside the receiving hopper 3. There are two tapping assemblies 42, which are respectively located at the lower ends of the left and right sides of the receiving hopper 3. The linkage assembly 43 is located below the filter assembly 41. The transmission assembly 44 is located at the rear right side of the receiving hopper 3.

[0023] The above solution involves setting up a filter flow control device 4 to perform a preliminary filtration of the rice in the receiving hopper 3, filtering out some impurities in the rice to facilitate processing after unloading, and controlling the flow rate of the rice to prevent blockage and ensure smoother flow of the rice in the receiving hopper 3.

[0024] refer to Figure 2 and Figure 3The filter assembly 41 includes two movable parts 411, a sieve plate 412, and filter holes 413. The number of movable parts 411 is two, and they are respectively disposed in two movable slots 5 and slidably connected to the two movable slots 5. The front and rear ends of the two movable parts 411 extend out of the movable slots 5. The sieve plate 412 is disposed in the receiving hopper 3 and slidably connected to the receiving hopper 3. The front and rear ends of the sieve plate 412 are respectively fixedly connected to the two movable parts 411 that are close to each other. The number of filter holes 413 is several, and they are evenly opened on the surface of the sieve plate 412 and penetrate the sieve plate 412.

[0025] The above solution involves setting up a filter component 41 to perform preliminary filtration of the rice in the hopper 3 and to control the flow rate of the rice.

[0026] refer to Figure 2 , Figure 3 and Figure 4 The striking assembly 42 includes a rotating seat 421, a striking plate 422, a tension spring 423, and a connecting rod 424. The rotating seat 421 is fixedly connected to the lower end of the left surface of the receiving hopper 3. The lower end of the striking plate 422 is sleeved on the surface of the rotating seat 421 and is rotatably connected to the rotating seat 421. There are two tension springs 423, which are respectively located at the front and rear ends of the right surface of the striking plate 422. The left and right ends of the two tension springs 423 are fixedly connected to the right surface of the striking plate 422 and the left surface of the receiving hopper 3, respectively. There are two connecting rods 424, which are respectively fixedly connected to the front and rear sides of the striking plate 422. The front right end of the connecting rod 424 is close to the moving part 411.

[0027] The above solution involves setting up a tapping component 42 to tap the hopper 3 to generate vibration, thereby preventing blockage and clearing blockages after they occur, allowing the rice to fall more smoothly.

[0028] refer to Figure 2 and Figure 3 The linkage component 43 includes a rotating rod 431 and an extrusion wheel 432. The rotating rod 431 is located inside the receiving hopper 3, and both the front and rear receiving hoppers 3 extend out of the receiving hopper 3 and are rotatably connected to the receiving hopper 3. There are two extrusion wheels 432, which are respectively sleeved on one end of the two rotating rods 431 extending out of the receiving hopper 3 and are fixedly connected to the rotating rods 431. The positions of the extrusion wheels 432 correspond to the positions of the moving part 411 and one end of the connecting rod 424.

[0029] The above solution is adopted: by setting up a linkage component 43, it is used to link the filter component 41 and the tapping component 42, and has the function of simultaneously driving the filter component 41 and the tapping component 42 to move.

[0030] refer to Figure 1The transmission assembly 44 includes a motor 441, a first pulley 442, a second pulley 443, and a belt 444. The motor 441 is fixedly connected to the right side of the receiving hopper 3, the first pulley 442 is fixedly connected to the output end of the motor 441, the second pulley 443 is fixedly connected to the rear end of the rotating rod 431, and the first pulley 442 and the second pulley 443 are connected by the belt 444.

[0031] The above scheme is adopted: by setting up a transmission component 44, it is used to drive and control the filter flow control device 4, which has the function of driving the linkage component 43 to rotate and link the filter component 41 and the tapping component 42.

[0032] refer to Figure 4 Rubber blocks 6 are provided at the upper and lower ends of the right surface of the clapper 422, and both rubber blocks 6 are fixedly connected to the clapper 422.

[0033] The above solution is adopted: rubber blocks 6 are set at the upper and lower ends of the right surface of the clapper 422 to directly strike the receiving hopper 3, thereby avoiding damage to the receiving hopper 3 caused by the direct striking of the clapper 422.

[0034] In use, rice is poured into the receiving hopper 3, and the motor 441 is started. The motor 441 drives pulley 1 442 to rotate, which in turn drives pulley 2 443 via belt 444. The rotation of pulley 2 443 drives the rotating rod 431 to rotate, which in turn drives the two pressing rollers 432 to rotate. When the two pressing rollers 432 rotate to the convex position, they press the two moving parts 411 at their far ends, causing the two moving parts 411 to move upward in the moving groove 5. At the same time, this moves the screen plate 412. When the convex position does not press the moving parts 411... The screen plate 412 will fall and reset due to pressure and its own weight, and this up-and-down lifting and bumping will perform filtration. At the same time, the rotation of the extrusion wheel 432 will cause the protrusion to squeeze the connecting rod 424, which will push the beater 422. The beater 422 will rotate counterclockwise on the surface of the rotating seat 421 around the center of the rotating seat 421, and at the same time stretch the tension spring 423. After the protrusion of the extrusion wheel 432 stops squeezing the connecting rod 424, the tension spring 423 will rebound and pull the beater 422 back, and beat the hopper 3, thereby filtering and preventing blockage.

[0035] In summary, this rice production and processing unloading device, through the coordinated use of a body 1, transmission device 2, receiving hopper 3, filter flow control device 4, filter assembly 41, moving part 411, sieve plate 412, filter holes 413, striking assembly 42, rotating seat 421, striking plate 422, tension spring 423, connecting rod 424, linkage assembly 43, rotating rod 431, extrusion wheel 432, transmission assembly 44, motor 441, pulley one 442, pulley two 443, belt 444, moving trough 5, and rubber block 6, solves the problems of existing hopper belt conveyors where some impurities in the rice poured into the receiving hopper are transported away, causing problems for subsequent processing, and the rice in the receiving hopper is prone to blockage due to uncontrolled and uneven flow rate, thus affecting unloading efficiency.
