[0001] The utility model relates to food processing technical field, especially a kind of raw material grading and screening device before food processing. BACKGROUND

[0002] Food processing refers to the food processing activities such as grain milling and feed processing, which directly use agricultural, forestry, animal husbandry and fishery products as raw materials. In the food processing process, in order to ensure the quality and consistency of the food processing raw materials, a screening device is needed to screen the processed raw materials.

[0027] The maximum diameter of the guide block 225 is smaller than that of the fixed frame 224.

[0028] As shown in the drawings, Figure 2 And Figure 4 The screening assembly 210 comprises two sieve plates 211 slidingly connected to the inner wall of the screening box 100, the aperture of the upper sieve plate 211 is larger than that of the lower sieve plate 211, the two sieve plates 211 are arranged obliquely, the lower end of the sieve plate 211 penetrates out of the screening box 100, a fixed rod 212 is fixedly connected between the opposite ends of the two sieve plates 211, a motor 213 is fixedly connected to one side of the screening box 100, the output shaft of the motor 213 penetrates into the interior of the screening box 100 and is fixedly connected with a cam 214, and the surface of the cam 214 is in close contact with the bottom end of the upper sieve plate 211.

[0029] In this embodiment, a plurality of discharging frames 222 are arranged above the upper end of the sieve plate 211, and the other side of the screening box 100 is communicated with two discharging frames, the lower end of the sieve plate 211 extends to the inner side of the corresponding discharging frame, when the motor 213 is started by the controller, the output shaft of the motor 213 drives the cam 214 to rotate, when the cam 214 rotates from the lowest point to the highest point and contacts the bottom end of the upper sieve plate 211, the cam 214 pushes the upper sieve plate 211 to move upward, and under the action of the fixed rod 212, the lower sieve plate 211 is driven to move upward, when the cam 214 rotates from the highest point to the lowest point and contacts the bottom end of the upper sieve plate 211, the sieve plate 211 moves downward under the action of its own weight and the raw materials above it and always contacts the surface of the cam 214, so that the two sieve plates 211 reciprocate to classify and screen the raw materials.

[0030] As shown in Figure 3 and Figure 4 , the surface of the fixed frame 224 is fixedly connected with a round rod 226, the other end of the three round rods 226 penetrates out of the screening box 100 and is fixedly connected with a mounting plate 227, one side of the screening box 100 is rotatably connected with a reciprocating lead screw 228, the other end of the reciprocating lead screw 228 and the surface of the output shaft of the motor 213 are fixedly connected with a bevel gear 2210, the two bevel gears 2210 are meshingly connected, the surface of the reciprocating lead screw 228 is provided with a moving plate 229, and the top end of the moving plate 229 is fixedly connected with the bottom end of the mounting plate 227.

[0031] In this embodiment, the surface of the round rod 226 is slidably connected with the inner wall of the screening box 100, and a moving groove matched with the round rod 226 is formed in the screening box 100, when the output shaft of the motor 213 drives the cam 214 to rotate, the two bevel gears 2210 are driven to rotate synchronously, thereby driving the reciprocating lead screw 228 to rotate, the reciprocating lead screw 228 has the form of two thread grooves with the same pitch and opposite rotation directions, and the two ends are connected by a transition curve, through the rotation of the reciprocating lead screw 228, the screw groove side pushes the slider in the screw groove to make axial reciprocating motion, therefore, when the reciprocating lead screw 228 rotates, the plurality of round rods 226 are driven to reciprocate through the moving plate 229 and the mounting plate 227, thereby driving the corresponding fixed frame 224 to reciprocate, the hose 223 deforms, and the connection between the hose 223 and the discharging frame 222 remains stable within the reciprocating range of the fixed frame 224.

[0032] As shown in Figure 5 , the surface of the guide block 225 is fixedly connected with a plurality of fixed plates 2211 arranged in a ring shape, and the overall shape of the fixed plate 2211 is trapezoidal. The surface of the guide block 225 is formed with a plurality of channels by the plurality of fixed plates 2211.

[0033] As shown in Figure 2As shown, a guide plate 230 is fixedly connected to the inner wall of the screening box 100, and the guide plate 230 is set at an inclination.

[0034] In this embodiment, the lower end of the guide plate 230 is located above the higher end of the lower screen plate 211. When the raw material falls from the upper screen plate 211, the guide plate 230 will guide the fallen raw material to the upper end of the lower screen plate 211.

[0035] like Figure 3 As shown, multiple fixing blocks 240 are fixedly connected to the inner bottom wall of the receiving frame 221. The vertical cross-section of the fixing block 240 is an isosceles triangle. The fixing blocks 240 are arranged between two adjacent unloading frames 222.

[0036] In use, the food ingredients are poured into the receiving frame 221. Simultaneously, the ingredients enter three discharging frames 222 and flow downwards through the flexible tubes 223 at the bottom of the discharging frames 222. The ingredients flowing downwards through the flexible tubes 223 pass through the fixed frame 224 and come into contact with the guide block 225. The ingredients then flow downwards between the surface of the guide block 225 and the inner wall of the fixed frame 224. Under the conical action of the multiple fixed plates 2211 and the guide blocks 225, the downward-flowing ingredients are dispersed. Simultaneously, by controlling the start motor 213, the cam 214 drives the upper screen plate 211, which in turn drives the lower screen plate 211 via the fixed rod 212. The raw materials are screened by reciprocating vibration, and the output shaft of motor 213 simultaneously drives two bevel gears 2210 to rotate, thereby causing the reciprocating screw 228 to drive the moving plate 229 to move back and forth. Under the action of mounting plate 227 and round rod 226, multiple fixed frames 224 are driven to move back and forth, thereby continuously changing the position of multiple fixed frames 224 above the screen plate 211. During the screening process, raw materials larger than the corresponding screen plate 211 aperture will be discharged from the discharge frame on the other side of the screening box 100 through the inclined surface of the screen plate 211, while raw materials larger than the corresponding screen plate 211 aperture will fall downward through the screen plate 211, thereby completing the grading and screening of food raw materials.

The specific model can be selected according to actual needs. At the same time, the motor 213 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
