Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a food crushing and sampling machine for food detection. Background Technique

[0002] Food is generally defined as substances for human consumption or drinking, including processed foods, semi-finished products and unprocessed foods. In a broad sense, food also includes raw materials for food production, substances and environments contacted during the planting and breeding processes of food raw materials, additives in food, all packaging materials, facilities that directly or indirectly contact food, and environments that affect the original quality of food, etc.

[0003] For example, a food crushing and sampling tool for food detection with the publication number of CN220932537U includes a cylinder with open upper and lower ends. The upper and lower ends of the cylinder are respectively detachably installed with an upper cover and a sampling container. A crushing mechanism for crushing food is detachably installed inside the cylinder. A bottom plate for closing the lower port of the cylinder is rotatably installed at the bottom of the cylinder. A driving component for driving the bottom plate to flip is installed on one side of the cylinder. After the bottom plate flips up or down, it is inclined to conduct the lower end of the cylinder for discharging the sample obtained after crushing into the sampling container. This utility model enables the crushing of food and the discharge of samples to be carried out in a relatively closed space, and the sample obtained after crushing can be directly discharged into the sampling container, which is not only beneficial to the acquisition of samples, reduces the residual amount of samples, but also makes the samples not easily contaminated and oxidized. In addition, the crushing mechanism (except the motor) and the cylinder can be cleaned separately, improving the cleaning effect.

[0004] The above patent is beneficial to the acquisition of samples and reduces the residual amount of samples. However, when crushing and sampling foods with a relatively hard texture such as nuts, directly crushing the nuts with the crushing cutter head will cause damage to the crushing cutter head, and the crushing effect is not good, which will greatly reduce the service life of the device for food detection of nuts.

[0005] Therefore, we propose a food crushing and sampling machine for food detection to solve the problems raised in the above text. Content of the Utility Model

[0006] The purpose of the utility model is to provide a food crushing and sampling machine for food detection to solve the problems raised in the above background technique, that is, when crushing and sampling foods with a relatively hard texture such as nuts, directly crushing the nuts with the crushing cutter head will cause damage to the crushing cutter head, and the crushing effect is not good, which will greatly reduce the service life of the device for food detection of nuts.

[0007] To achieve the above object, the present utility model provides the following technical solution: A food crushing and sampling machine for food detection, comprising an outer housing and support legs fixedly installed at four corners of the lower end of the outer housing. A feed inlet is fixedly installed on the side of the outer housing, and a discharge pipe is fixedly installed at the lower end of the outer housing. A driving structure is installed on the outer housing. The driving structure includes a protective cover fixedly installed at the upper end of the outer housing. A motor is fixedly installed inside the protective cover. The output end of the motor is fixedly installed with a rotating rod. A fixing plate is fixedly installed inside the outer housing. A reciprocating component is movably installed on the fixing plate. The lower end of the rotating rod is installed with a connecting rod, and a crushing cutter head is fixedly installed on the connecting rod.

[0008] Preferably, the reciprocating component includes a cylindrical cam fixedly installed between the rotating rod and the connecting rod. A chute is provided on the side wall of the cylindrical cam.

[0009] Preferably, a connecting block is slidably connected inside the chute, and a movable block is fixedly installed on the side wall of the connecting block.

[0010] Preferably, a movable rod is fixedly installed on the side wall of the movable block, and the movable rod is slidably connected inside the outer housing.

[0011] Preferably, a concave barrel is fixedly installed inside the outer housing. An inclined ring is fixedly installed at the lower end of the concave barrel, and a sieve is fixedly installed inside the inclined ring.

[0012] Preferably, a pressing block is fixedly installed at one end of the movable block. A fixing rod is fixedly installed between the concave barrel and the sieve. The pressing block is slidably connected to the connecting rod and the fixing rod. An aggregation ring is fixedly installed at the lower end of the inner wall of the outer housing.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. Start the motor, and the food detection sample to be crushed enters the inside of the outer housing through the feed inlet. The output end of the motor drives the rotating rod and the reciprocating component to roll and crush the food sample. After the rolling and crushing, the food sample continues to fall downward around the crushing cutter head to further refine and crush the crushed food sample. Before crushing relatively hard nut foods, the food crushing and sampling machine for food detection first crushes the nuts by driving the reciprocating component with the motor and then directly drops the crushed nuts into small particles into the working range of the crushing cutter head. The crushing cutter head further crushes and refines it, making the food sample more thoroughly crushed and having a certain protective effect on the crushing cutter head, which can extend the service life of the device.

[0015] 2. With the cooperation among the concave barrel, the inclined ring, the sieve mesh, the gathering ring, the rolling block, the fixing rod, the support leg, the driving structure, the protective cover, the motor, the rotating rod, the connecting rod, the crushing cutter head, the cylindrical cam, the sliding groove, the connecting block, the movable block and the movable rod, the device can repeatedly roll and crush the nuts before crushing and sampling them, causing them to be broken into small particles that can pass through the sieve mesh and then fall down to the working range of the crushing cutter head for secondary crushing, with better crushing and refinement effects.

A fixed plate 13 is fixedly installed inside the external housing 1. A reciprocating component 4 is movably installed on the fixed plate 13. The lower end of the rotating rod 33 is installed with a connecting rod 34, and a crushing cutter head 35 is fixedly installed on the connecting rod 34.

[0023] In this embodiment: When crushing and sampling relatively hard foods such as nuts, start the motor 32, and pass the food detection sample to be crushed into the interior of the external housing 1 through the feed inlet 11. When the motor 32 starts, its output end drives the rotating rod 33 to rotate. The rotating rod 33 drives the reciprocating component 4 to roll and crush the food sample. After the rolling and crushing, the food sample continues to fall downward around the crushing cutter head 35. The connecting rod 34 rotates to drive the crushing cutter head 35 to rotate rapidly, further refining and crushing the crushed food sample. Before crushing relatively hard nut foods with this food crushing and sampling machine for food detection, the motor 32 drives the reciprocating component 4 to first crush the nuts and then directly drop the crushed nuts into small particles into the working range of the crushing cutter head 35. The crushing cutter head 35 further crushes and refines it, making the food sample more thoroughly crushed and having a certain protective effect on the crushing cutter head 35, which can extend the service life of the device.

[0024] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figure 2 - Figure 4 , The reciprocating component 4 includes a cylindrical cam 41 fixedly installed between the rotating rod 33 and the connecting rod 34. A chute 42 is provided on the side wall of the cylindrical cam 41.

[0025] A connecting block 43 is slidably connected in the chute 42. A movable block 44 is fixedly installed on the side wall of the connecting block 43. When the cylindrical cam 41 rotates, it drives the connecting block 43 to slide along the chute 42.

[0026] A movable rod 45 is fixedly installed on the side wall of the movable block 44. The movable rod 45 is slidably connected inside the external housing 1. When the cylindrical cam 41 rotates, it will drive the movable rod 45 to move up and down.

[0027] A concave barrel 14 is fixedly installed inside the external housing 1. An inclined ring 15 is fixedly installed at the lower end of the concave barrel 14. A screen 16 is fixedly installed inside the inclined ring 15.

[0028] One end of the movable block 44 is fixedly installed with a rolling block 18. A fixing rod 19 is fixedly installed between the concave barrel 14 and the screen 16. The rolling block 18 is slidably connected to the connecting rod 34 and the fixing rod 19. The lower end of the inner wall of the outer shell 1 is fixedly installed with an aggregation ring 17. The rolling block 18 can be driven by the movable rod 45 to move up and down to roll the nuts that fall onto the screen 16.

[0029] In this embodiment: When taking a pulverized sample of nuts, first, the nuts enter the interior of the outer shell 1 through the feed port 11. The nuts fall down along the concave barrel 14 onto the rolling block 18. After the nuts fall onto the rolling block 18, they slide down along the side wall of the rolling block 18 and fall onto the screen 16. When the motor 32 starts to drive the cylindrical cam 41 to rotate, it drives the connecting block 43 sliding along its chute 42 to move up and down along the chute 42. When the connecting block 43 moves up and down, it drives the movable rod 45 to reciprocate up and down inside the outer shell 1. When the movable rod 45 moves, it drives the rolling block 18 at the lower end to move up and down, and initially rolls and crushes the nuts between the rolling block 18 and the screen 16. The smaller nut particles after rolling and crushing fall down through the mesh holes on the screen 16 into the active area of the crushing cutter head 35 and are further refined and crushed by the crushing cutter head 35. This device can repeatedly roll and crush the nuts before taking a pulverized sample of the nuts, causing them to be broken into small particles that can pass through the screen 16 and then fall down into the working range of the crushing cutter head 35 for secondary crushing, and the pulverizing and refining effect is better.
