Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

The stabilizing block 213 matches the stabilizing groove 214. When it is necessary to remove the middle screening bin 201, by starting the two electrically controlled automatic telescopic rods 205, the two fixing rings 208 move upward and respectively enter the interiors of the two fixing grooves 207, thereby driving the corresponding mounting plates 206 to move upward. The distances between the groups of fixing rings 208 are different, so that there is a certain interval between the groups of screening bins 201 after rising, thereby lifting the corresponding screening bin 201 upward. After the fixing ring 208 is disengaged from the fixing groove 207, the corresponding screening bin 201 can be removed. After the disassembly and installation are completed, the two electrically controlled automatic telescopic rods 205 work again to make the top plate 209 move downward. Among them, the two stabilizing blocks 213 are both clamped inside the two stabilizing grooves 214, so that the groups of screening bins 201 are fixed and installed more firmly.

[0027] The sieve plate 202 is inclined, and the discharge outlet 204 is located on the left side of the sieve plate 202, so that the screened food can be discharged from the discharge outlet 204 more smoothly.

[0028] Limit plates 210 are fixedly connected to both sides of the top of the top screening bin 201. The top plate 209 matches the two limit plates 210, so that the screening bin 201 can be fixed more firmly.

[0029] Anti-slip blocks 211 are fixedly connected to both sides of the outer wall of the screening bin 201, which facilitates the disassembly of the screening bin 201.

When the screening plate 202 is damaged or needs to be replaced, the corresponding screening bin 201 is first removed by the installation component, and then the positioning blocks 308 on both sides are pushed to disengage them from the inside of the positioning grooves 309 on both sides. At this time, the screening plate 202 can be easily removed. When it needs to be installed, the positioning blocks 308 on both sides are pushed again to push the screening plate 202 into the screening bin 201, so that the positioning blocks 308 on both sides enter the inside of the positioning grooves 309 on both sides again, so that the screening plate 202 can be fixedly installed.

[0032] The interior of the mounting grooves 306 on both sides are fixedly connected with limit rods 310 , and the limit rods 310 on both sides penetrate the bodies of the positioning blocks 308 on both sides, so that the movement of the positioning blocks 308 on both sides is more stable.

[0033] Working principle: When it is necessary to remove the screening bin 201 in the middle, by starting the electric control automatic telescopic rods 205 on both sides, the fixed rings 208 on both sides move upward and respectively enter the interiors of the fixed slots 207 on both sides, thereby driving the corresponding mounting plates 206 to move upward. The distances between the groups of fixed rings 208 are different, so that there is a certain interval between the groups of screening bins 201 after they rise, thereby lifting the corresponding screening bin 201 upward. After the fixed ring 208 is disengaged from the fixed slot 207, the corresponding screening bin 201 can be removed. After the disassembly and installation are completed, the electric control automatic telescopic rods 205 on both sides work again, causing the top plate 209 to move downward. The stabilizing blocks 213 on both sides are respectively clamped in the stabilizing slots 214 on both sides, making the fixed installation of each group of screening bins 201 more firm. By starting the bidirectional motor 300, the driving blocks 302 on the outer walls of the rotating shafts 301 on both sides rotate, causing the driving blocks 302 to continuously contact the arc-shaped blocks 303. In cooperation with the first springs 305 on both sides, the base 200 and the screening bin 201 vibrate up and down continuously, enabling the food raw materials to quickly pass through the multiple groups of sieve plates 202 and be discharged from their respective discharge ports 204. When the sieve plate 202 is damaged or needs to be replaced, first, the corresponding screening bin 201 is removed through the installation component. Secondly, the positioning blocks 308 on both sides are pushed to disengage them from the interiors of the positioning slots 309 on both sides. At this time, the sieve plate 202 can be easily removed. When it is necessary to install it, the positioning blocks 308 on both sides are pushed again, and the sieve plate 202 is pushed into the screening bin 201, causing the positioning blocks 308 on both sides to enter the interiors of the positioning slots 309 on both sides again, thereby enabling the fixed installation of the sieve plate 202.
