DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be described in further detail below in conjunction with the drawings. Only this statement, the up, down, left, right, front, back, inside, outside and other directions of the utility model appearing or about to appear in the text of the utility model, only with the drawings of the utility model as the base, it is not the specific limitation of the utility model.

[0021] A food raw material grading and screening device, as shown in Figures 1-5 The left and right two support frames 1 are slidably connected with the vibrating screen 2 between them, the vibrating screen 2 is provided with a discharge port in the front lower part, facilitating discharging, the first telescopic springs 3 are connected between the vibrating screen 2 and the front and rear parts of the support frame 1, the fixed frame 4 is connected to the right side of the vibrating screen 2, the motor 5 is connected to the fixed frame 4, the eccentric wheel 6 is connected to the output shaft of the motor 5, the vibration frame 7 is slidably connected to the front upper part of the vibrating screen 2, the hopper 8 is connected to the upper side of the vibration frame 7, the seven shunt plates 9 are connected to the hopper 8, the screw 10 is rotatably connected to the front part of the hopper 8, the knob is arranged on the upper side of the screw 10, facilitating gripping, the blocking frame 11 is threadedly connected to the screw 10, the blocking frame 11 is slidably connected with the hopper 8, the shunt plates 9 are in contact with the blocking frame 11, the second telescopic springs 12 are connected between the hopper 8 and the vibrating screen 2 between the left and right parts, the rotating shaft 14 is rotatably connected to the front part of the vibrating screen 2, the belt pulley is arranged on the right part of the rotating shaft 14, the belt pulley is also arranged on the output shaft of the motor 5, the eccentric wheel 6 is located to the left of the adjacent belt pulley, the flat belt 13 is wound between the belt pulleys, the cam 15 is connected to the left part of the rotating shaft 14, the cam 15 is in contact with the vibration frame 7.

[0022] When using this device, first place the support frame 1 in the food raw material grading and screening area, then turn the screw 10 by the knob to move the blocking frame 11 under the action of the screw. Adjust the height of the blocking frame 11 according to the overall size of different food raw materials. The larger the food raw material, the higher the blocking frame 11 should be adjusted. After adjustment, discharge the food raw material into the feeding hopper 8. At the same time, start the motor 5 on the fixed frame 4 to drive the eccentric wheel 6 and the pulley to rotate. Through the transmission between the pulley and the flat belt 13, the rotating shaft 14 is driven to rotate, causing the cam 15 to rotate. The cam 15 strikes the vibrating frame 7, causing the vibrating frame 7 to move up and down, which in turn causes the feeding hopper 8 to move up and down, causing the second telescopic spring 12 to move up and down. The deformation of the first extension spring 3 causes the food material on the hopper 8 to vibrate under the action of the second extension spring 12. The food material is then diverted by the diversion plate 9 and falls onto the vibrating screen 2. This vibration and diversion of the food material during feeding prevents accumulation and ensures that the food material enters the vibrating screen 2 evenly, thus improving production efficiency. At the same time, the eccentric wheel 6 causes the vibrating screen 2 to move up and down, causing the first extension spring 3 to deform. Under the action of the first extension spring 3, the food material vibrates, causing larger food materials to remain above the vibrating screen 2, while smaller food materials are screened and discharged from the outlet. This vibrating screen 2 separates the food material and improves screening efficiency.
