Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] The first servo motor 105 in this utility model is a common electrical device in the prior art, and this application will not elaborate on its model or internal structure.

[0027] As shown in Figures 1-4, this utility model provides a technical solution: a food crushing and sampling device for food testing, comprising a crushing mechanism 1, characterized in that: a crushing mechanism 2 is provided above the crushing mechanism 1, the crushing mechanism 2 includes a support frame 201 and a connecting block 207, a conical cylinder 202 is fixedly connected to the upper part of the support frame 201, a feed inlet 203 is opened on the upper part of the outer surface of the conical cylinder 202, a baffle 204 is fixedly connected to the upper surface of the conical cylinder 202, a threaded tube 205 is slidably connected to the baffle 204, a pressing block 206 is fixedly connected to the bottom end of the threaded tube 205, a support cylinder 215 is fixedly connected to the upper surface of the baffle 204, a second servo motor 216 is fixedly installed on the upper surface of the support cylinder 215, a threaded rod 217 is fixedly connected to the rotating shaft of the second servo motor 216, and the outer surface of the threaded rod 217...

The front of the connecting block 207 has a pull groove 209. The front of the connecting block 207 has two sets of symmetrical circular grooves 210. The inner walls of the two sets of circular grooves 210 are fixedly connected to elastic elements 211. The front end of the elastic element 211 is fixedly connected to a limit plate 212. The back of the limit plate 212 is fixedly connected to a baffle 213. The lower surface of the connecting block 207 is fixedly connected to a connecting tube 214. The outer surface of the pressure block 206 is slidably connected to the inner wall of the conical cylinder 202. The upper surface of the connecting block 207 is fixedly connected to the bottom end of the conical cylinder 202. The through hole 208 is connected to the interior of the conical cylinder 202. The baffle 213 is inserted into the pull groove 209. The top end of the connecting tube 214 is connected to the through hole 208.

[0028] The elastic element 211 is preferably made of spring. The rear end of the elastic element 211 is fixedly connected to the innermost circular plane of the inner side wall of the circular groove 210. After the baffle 213 is inserted into the pull-out groove 209, it can block the middle position of the through hole 208, so that the through hole 208 cannot be passed through vertically. The connecting pipe 214 is preferably made of stainless steel pipe.

[0029] Food is fed into the conical cylinder 202 through the feed inlet 203. Then, the control 216 rotates left and right, which drives the pressing block 206 to continuously squeeze the food inside the conical cylinder 202. After the food is crushed, the limiting plate 212 is pulled out, which in turn drives the baffle 213 to move in the same direction as the limiting plate 212. This releases the baffle 213 from blocking the through hole 208, allowing the crushed food inside the conical cylinder 202 to enter the crushing mechanism through the connecting pipe 214. This device can crush round or near-round food, achieving the purpose of quickly crushing round or near-round food.

[0030] The crushing mechanism 1 includes a support plate 101. Two sets of symmetrical support legs 102 are fixedly connected to the lower surface of the support plate 101. A threaded tube 103 is fixedly connected to the lower surface of the support plate 101. A threaded cylinder 104 is threadedly connected to the bottom end of the threaded tube 103. A first servo motor 105 is fixedly installed on the upper surface of the support plate 101. A rotating rod 106 is fixedly connected to the output shaft of the first servo motor 105. The bottom end of the rotating rod 106 passes through a circular hole opened at the center of the support plate 101.

The upper surface of the support plate 101 is fixedly connected to the bottom end of the connecting tube 214. The threaded tube 103 is connected to the connecting tube 214 through a circular hole opened on the front side of the upper surface of the support plate 101.

[0031] The crushing blade assembly 107 here is existing technology and will not be described in detail. The crushing blade assembly 107 is located at the bottom inside the threaded cylinder 104.

[0032] By controlling the rotation of the first servo motor 105, the rotating rod 106 is driven to rotate, which in turn drives the pulverizing blade assembly 107 to rotate, and pulverizes the food inside the threaded cylinder 104. After the food is pulverized, the threaded cylinder 104 is de-threaded from the threaded tube 103, and the pulverized food can be quickly removed, thus achieving the purpose of this device to conveniently remove the pulverized food.

[0033] Working principle: In use, food is first filled into the conical cylinder 202 through the feed inlet 203. Then, the control 216 rotates left and right, which drives the pressing block 206 to continuously squeeze the food inside the conical cylinder 202. After the food is crushed, the limiting plate 212 is pulled out, which in turn drives the baffle 213 to move in the same direction as the limiting plate 212. This releases the obstruction of the through hole 208 by the baffle 213, allowing the crushed food inside the conical cylinder 202 to enter the crushing mechanism through the connecting pipe 214. This device can crush round or near-round food, achieving the desired crushing effect. The purpose of this device is to quickly crush round or near-round food. The crushed food falls into the threaded cylinder 104 through the round hole on the front side of the upper surface of the support plate 101. By controlling the rotation of the first servo motor 105, the rotating rod 106 is driven to rotate, which in turn drives the crushing blade assembly 107 to rotate, and crushes the food inside the threaded cylinder 104. After the food is crushed, the threaded cylinder 104 is de-threaded from the threaded tube 103, and the crushed food can be quickly removed, thus achieving the purpose of conveniently removing the crushed food.
