[0029] Specifically, by discharging raw materials along feed hopper 2 to sieve plate 15, driving rod 5 is moved along movable slot 11 by vibration assembly 9, driving rod 5 drives sieve plate 15 to move, so that sliding block 16 on sieve plate 15 reciprocatingly slides along sliding groove 19, thereby realizing the vibration of multiple sieve plates 15, since the diameter of sieve hole on multiple sieve plates 15 gradually decreases from top to bottom, thereby realizing multi-stage screening of raw materials, at the same time, since sieve plate 15 is obliquely arranged from feed hopper 2 to sieve discharge port 8, raw materials after screening along the inclined surface of sieve plate 15 are rolled to sieve discharge port 8 and discharged, realizing the collection of raw materials after screening, secondly, raw materials after screening by the lowest sieve plate 15 are discharged along discharge hopper 12, the overall structure is simple to operate, the design of multiple sieve plates 15 and decreasing sieve hole can finely grade and screen food raw materials, meet the various requirements of different food production processes on raw material particle size, improve the accuracy and comprehensiveness of screening, thereby improving product quality, at the same time, the stability of multiple sieve plates 15 is higher when vibrating, ensuring normal screening work of the device on raw materials.

[0030] It should be noted that, in the present embodiment, discharge hopper 12 and feed hopper 2 are both funnel-shaped structures, the number of sieve plates 15 is not limited, and can be adjusted according to actual conditions, feed hopper 2 is arranged at the highest position of sieve plate 15 on the top of device body 1; further, vibration motor 91 is a structure that can drive driving rod 5 to move along movable slot 11, for example, multiple vibration motors 91 respectively drive driving rod 5 to move along movable slot 11, thereby realizing the vibration of sieve plate 15, or the vibration of sieve plate 15 is realized by the arrangement of motor 91 and cam, when the cam is separated from driving rod 5, driving rod 5 is reset under the weight of sieve plate 15, that is, the reciprocating motion of driving rod 5 is realized, thereby realizing the vibration of sieve plate 15.

[0031] In the embodiment of the utility model, Figure 1 And Figure 2As shown, the vibration assembly 9 comprises a rack 93, a plurality of driving rods 5 movably connected with the rack 93, a motor 91 mounted on the outer wall of the device body 1, a half gear 92 sleeved with the rack 93 on the driving end of the motor 91, a support block 4 fixedly connected on the device body 1, a tension spring 3 fixedly connected on the support block 4, one end of the tension spring 3 away from the support block 4 connected with the rack 93, and a controller 6 for controlling the motor 91 provided on the device body 1. Specifically, the controller 6 controls the motor 91 to start, and the motor 91 drives the half gear 92 to rotate. When the teeth of the half gear 92 are engaged with the rack 93, the rack 93 will move to one side under the push of the teeth. When the teeth of the half gear 92 are disengaged, the rack 93 moves back under the tension of the tension spring 3. Since the plurality of driving rods 5 are rotatably arranged on the rack 93, the reciprocating linear motion of the rack 93 will drive the driving rods 5 to reciprocate up and down or left and right (depending on the connection mode of the driving rods 5 and the rack 93), thereby causing the sieve plate 15 to vibrate. This vibration helps the material to jump and loosen on the sieve plate 15, prevents the material from blocking the sieve holes, and improves the screening efficiency. In addition, the setting of the tension spring 3 optimizes the working performance of the vibration assembly 9, reduces the unstable vibration caused by mechanical inertia and other factors, and prolongs the service life of the equipment.

[0032] In the embodiment of the utility model, as shown in Figure 2 , Figure 4 , Figure 6 and Figure 7 , the inner wall of the device body 1 between the sieve plate 15 and the screening discharge port 8 is fixedly connected with a support plate 13, and the support plate 13 is fixedly connected with a guide hopper 10. The guide hopper 10 has an inclined surface that connects the sieve plate 15 and the screening discharge port 8. Specifically, after the material on the sieve plate 15 is screened, it falls into the guide hopper 10 on the support plate 13 through the sieve holes. The inclined surface of the guide hopper 10 guides the material to the screening discharge port 8, allowing the material to be smoothly transferred from the sieve plate 15 to the corresponding discharge channel, preventing the material from accumulating or spilling between the sieve plate 15 and the discharge port. The design of the guide hopper 10 ensures that the undersize material can be accurately and efficiently discharged, preventing the material from being retained below the sieve plate 15 and affecting the screening efficiency or causing equipment blockage. Further, the discharge end of the sieve plate 15 is fixedly connected with a guide plate 14 inclined towards the guide hopper 10. When the material slides to the discharge end on the sieve plate 15, the guide plate 14 further concentrates and guides the material to flow to the guide hopper 10, making the discharge path of the material more accurate and smooth, reducing the possibility of material spilling at the edge of the sieve plate 15.

[0033] In the embodiment of the utility model, as shown in Figure 4 , Figure 6 and Figure 7As shown, the baffle 18 is fixedly connected to the screen plate 15. Specifically, the baffle 18 has three pieces, which are respectively installed on the other three end faces of the screen plate 15 except the discharge end. The baffle 18 on the screen plate 15 can limit the flow range of the material during the material screening process, prevent the material from sliding off from both sides of the screen plate 15, make the distribution of the material on the screen plate 15 more uniform, ensure that the material can pass through the screen hole for screening, and improve the accuracy and integrity of the screening.

[0034] Working principle: by discharging the raw materials on the screen plate 15 along the feeding hopper 2, the controller 6 controls the motor 91 to start, the motor 91 drives the half gear 92 to rotate, when the teeth of the half gear 92 engage with the rack 93, the rack 93 will move to one side under the push of the teeth; when the teeth of the half gear 92 disengage, the rack 93 moves back under the pulling force of the tension spring 3, since the driving rods 5 are penetrated and rotationally arranged on the rack 93, the reciprocating linear motion of the rack 93 will drive the driving rods 5 to make reciprocating motion up and down or left and right (depending on the connection mode of the driving rods 5 and the rack 93), thereby making the screen plate 15 vibrate, thereby realizing the vibration of the multiple screen plates 15, since the diameters of the screen holes on the multiple screen plates 15 gradually decrease from top to bottom, thereby realizing the multi-stage screening of the raw materials, at the same time, since the screen plate 15 is inclinedly arranged from the feeding hopper 2 to the screening discharge port 8, the raw materials screened by the screen plate 15 roll along the inclined surface to the screening discharge port 8 for discharge, realizing the collection of the screened raw materials, in addition, the raw materials screened by the lowest screen plate 15 are discharged along the discharge hopper 12, the overall structure is simple to operate, the design of the multiple screen plates 15 and the decreasing screen holes can finely grade and screen the food raw materials, meet the multiple requirements of different food production processes on the particle size of the raw materials, improve the precision and comprehensiveness of the screening, thereby improving the product quality, at the same time, the stability of the multiple screen plates 15 is higher when vibrating, thereby ensuring the normal screening work of the device on the raw materials.
