[0022] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe the detailed implementation manners of the present utility model with reference to the accompanying drawings of the specification.

[0023] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0024] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or selectively exclusive embodiment from other embodiments.

[0025] As shown in the attached Figure 1 to the attached Figure 4 figures:

[0026] Embodiment 1: This embodiment provides a crushing and screening device for food detection, including a main body 1, including a screening box 101 and a crushing box 102 provided on the top of the screening box 101; a screening mechanism 2, including a frame 1 201 provided in the upper part of the screening box 101, a frame 2 202 provided in the lower part of the screening box 101, a filter screen 203 provided on the frame 1 201, a placing plate 204 provided on the frame 2 202, and a feeding assembly 206 provided between the frame 1 201 and the frame 2 202; the feeding assembly 206 includes a motor 2063 provided at the front end of the screening box 101, a driving gear 2064 provided at the output end of the motor 2063, a rack 1 2061 provided at the bottom of the frame 1 201, and a rack 2 2062 provided at the top of the frame 2 202; an auxiliary mechanism 3 is provided on the screening box 101.

[0027] Specifically, the driving gear 2064 is located between the first frame 201 and the second frame 202, and the driving gear 2064 meshes with the first rack 2061 and the second rack 2062 respectively.

[0028] Specifically, limit gears 2065 are arranged in the screening boxes 101 on both sides of the driving gear 2064, and the two limit gears 2065 mesh with the first rack 2061 and the second rack 2062 respectively.

[0029] Specifically, baffles 207 are arranged through the screening boxes 101 at the front ends of the first frame 201 and the second frame 202. A vibrator 208 is arranged on the baffle 207 at the front end of the first frame 201. Shielding shells 205 are arranged on the tops of the filter screen 203 and the placing plate 204.

[0030] As can be seen from the above, during operation, the food sample to be processed is put into the crushing box 102. The crushing box 102 will crush the food sample. The crushed food sample will fall into the screening box 101. The food sample will be pre-placed on the filter screen 203. The vibrator 208 is started. The vibrator 208 will drive the filter screen 203 to vibrate to filter the food sample. The food sample with the crushing specification meeting the requirements will pass through the filter screen 203 and fall on the placing plate 204 for centralized storage. The video sample with the crushing specification not meeting the requirements will be blocked by the filter screen 203, realizing the screening of the food sample and facilitating the subsequent inspection work of the staff using the food sample meeting the requirements;

[0031] Before operation, the crushing and screening time can be preset on the controller. When the preset time is reached, the motor 2063 is started. The motor 2063 will drive the driving gear 2064 to rotate. Then, through the meshing of the driving gear 2064 with the first rack 2061 and the second rack 2062, the first frame 201 and the second frame 202 are driven to move synchronously and reversely until they protrude out of the screening box 101. At this time, the first frame 201 and the second frame 202 will be located on both sides of the device respectively, with no obstruction above, facilitating personnel to observe the crushing and screening situation and take samples.

[0032] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the auxiliary mechanism 3 includes a fixing plate 301 arranged on one side of the screening box 101, a supplementary light 302 arranged at the bottom of the fixing plate 301, a ranging sensor 304 arranged at the bottom of the fixing plate 301, and a warning light 303 arranged at the top of the fixing plate 301.

[0033] Specifically, the ranging sensor 304 corresponds to the first rack 2061. Both between the first frame 201 and the filter screen 203 and between the second frame 202 and the placing plate 204 are threadedly connected through connecting bolts 305.

[0034] As can be seen from the above, when the motor 2063 drives the first rack 2061 to move and move it away from the bottom of the ranging sensor 304, the second frame 202 with the same moving speed as the first rack 2061 will pop out of the screening box 101 and move to the bottom of the ranging sensor 304. Since the detected length information changes, the ranging sensor 304 will use the controller to control the supplementary light 302 to turn on, so as to supplement light and illuminate the crushed qualified food samples on the placing plate 204 in the second frame 202, facilitating personnel to view. At the same time, the warning light 303 will be started synchronously to prompt the staff, indicating that the crushing and screening are completed, avoiding the situation that the staff forgets due to being busy with other things. And the connecting bolt 305 can be rotated to separate the filter screen 203 from the first frame 201 and the placing plate 204 from the second frame 202, facilitating personnel to completely pour out the crushed qualified and uncrushed qualified food samples for use and processing.

[0035] This design application is used for the detection of food samples in the laboratory. After the large food samples are introduced into the crushing box 102, they will be crushed. After the crushing is completed, they will fall into the screening box 101 for screening. The qualified and unqualified food samples after screening will be located on the filter screen 203 and the placing plate 204 respectively. The feeding assembly 206 is used to drive them synchronously to both sides of the screening box 101, facilitating personnel to directly view the crushing and screening situation and facilitating personnel to pick and use.
