[0023] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present utility model.

[0024] It should be noted that: Similar reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0025] This embodiment mainly elaborates on the structure of the discharge screening device, as follows:

[0026] A discharge screening device for a food crusher, as Figures 1-5As shown in the figure, it includes a food crusher 1, a discharge pipe 2, a blower 3 and a screen 4. The discharge pipe 2 is fixedly connected to the food crusher 1, and the material of the discharge pipe 2 is stainless steel. The bottom of the food crusher 1 is fixedly connected by bolts with a blower 3 for blowing the crushed food. The blower 3 is a small DC blower, and the air outlet of the blower 3 faces the discharge pipe 2 to assist the discharge and preliminary dispersion of food particles by wind power. A screen 4 is slidably connected to the right side of the discharge pipe 2 for screening the discharged food particles to ensure that only fine particles that meet the requirements can pass through, while large particles or impurities are intercepted. The screen 4 is made of stainless steel woven wire and needs to be replaced with different mesh sizes according to requirements to screen the food particles. It also includes a support base 5 and a collection box 6. A support base 5 is welded to the middle of the discharge pipe 2. The support base 5 is provided with a slide rail and a limit groove for slidably connecting the collection box 6. The collection box 6 is slidably connected to the support base 5 for collecting the unqualified food particles intercepted by the screen 4 during the screening process, which is convenient for subsequent processing. The collection box 6 is made of transparent plastic material to facilitate observing the internal material situation. It also includes a limit block 7 and a torsion spring 8. Limit blocks 7 for preventing the collection box 6 from slipping are symmetrically provided on the right side of the support base 5. The limit blocks 7 are slidably connected to the support base 5, and a torsion spring 8 is sleeved on the limit blocks 7. The two ends of the torsion spring 8 are respectively fixedly connected to the limit blocks 7 and the support base 5. It also includes a guide rod 9, a clamping plate 10 and a spring 11. The guide rod 9 is fixedly connected to the outlet of the discharge pipe 2. A clamping plate 10 for clamping a collection bag is slidably connected to the guide rod 9. A spring 11 is sleeved between the guide rod 9 and the clamping plate 10. One end of the spring 11 is fixedly connected to the guide rod 9, and the other end of the spring 11 is fixedly connected to the clamping plate 10. It also includes a magnet 12 for preventing the screen 4 from slipping. The magnet 12 is fixedly connected to the left side of the screen 4. It also includes a turbulence block 13 for preventing the formation of eddy currents inside the discharge pipe 2. The turbulence block 13 is fixedly connected to the inner wall of the discharge pipe 2.

[0027] Before starting the food crusher 1, the operator first replaces the sieve 4 with a sieve 4 of appropriate size. To prevent the sieve 4 from accidentally slipping during use, a magnet 12 is fixedly connected to the left side of the sieve 4, which attracts the discharge pipe 2, thereby ensuring the stability of the sieve 4. Then, the clamping plate 10 is pulled outwards. At this time, the spring 11 is compressed. The opening of the collection bag is put on the discharge pipe 2, and then the clamping plate 10 is released. The spring 11 will automatically reset and tightly clamp the collection bag below, effectively preventing the leakage of food particles during the discharging process. After completion, the raw materials are put into the food crusher 1 and crushed by the high-speed rotating blades inside to form food particles of different sizes. Under the action of gravity and centrifugal force, the crushed food particles naturally fall to the bottom of the food crusher 1 and close to the position of the discharge pipe 2. At this time, the blower 3 installed at the bottom of the food crusher 1 is started, and its air outlet is directly facing the discharge pipe 2. The wind generated by the blower 3 directly acts on the food particles, assisting them to pass through the discharge pipe 2 more smoothly and realizing preliminary dispersion during the discharging process, reducing the agglomeration phenomenon between the particles. A spoiler 13 is also fixedly connected to the inner wall of the discharge pipe 2 to break the eddy current of the air flow and material flow, promoting the uniform distribution of the material in the discharge pipe 2 and further improving the screening effect. When the food particles are discharged through the discharge pipe 2, they will contact the sieve 4. The fine particles that meet the requirements can smoothly pass through the mesh holes of the sieve 4 and continue to be discharged downward, while the large particles or impurities are intercepted on the sieve 4 because they cannot pass through the mesh holes. The unqualified food particles intercepted by the sieve 4 will naturally fall into the collection frame 6, which is convenient for subsequent unified treatment or re-crushing. To prevent the collection frame 6 from accidentally slipping during the collection process, limit blocks 7 are symmetrically arranged on the right side of the support seat 5. Before the collection frame 6 is pushed into the mounting seat, the limit blocks 7 are rotated, so that the torsion spring 8 is compressed. After being placed in the mounting seat, the limit blocks 7 are released, and the limit blocks 7 will reset under the action of the torsion spring 8 to complete the limitation of the collection frame 6. When the collection frame 6 needs to be taken out, just gently rotate the limit blocks 7 on the front and back sides, and the collection frame 6 can be taken out, maintaining the stability of the collection frame 6.

[0028] As Figure 1 shown, it also includes a handle 14 for facilitating the movement of the food crusher 1. The handle 14 is fixedly connected to the food crusher 1. The handle 14 fixedly connected to the food crusher 1 enables the operator to easily move the entire device, facilitating the transfer between different working areas.

[0029] As Figure 1 shown, it also includes a dust-proof cover 15 for preventing foreign objects from entering the food crusher 1. The dust-proof cover 15 is snap-connected to the top of the food crusher 1. The dust-proof cover 15 installed on the top of the food crusher 1 effectively prevents foreign objects from entering the equipment, ensuring the cleanliness of the processing environment and food safety.
