Description

Technical Field

[0001] This utility model relates to the field of food safety testing technology, and in particular to a grain sample crushing and processing device that prevents clogging. Background Technology

[0002] In the process of import and export trade of grains and their products, crushing devices are used when testing the products. These devices are used to crush grain samples before analysis. However, existing crushing devices for grain product testing have problems such as low efficiency and uneven crushing when used in the later stages. The processed particles are not uniform and fine enough, and the crushing is not efficient or accurate enough, and the operation is relatively cumbersome.

[0003] Chinese Patent No. CN223055756U discloses a pulverizing device for testing grain products, specifically relating to the field of food safety testing. The device includes a base plate with multiple reinforcing supports fixedly connected to its upper surface. A pulverizing cylinder is fixedly connected to the top of each of the reinforcing supports. A square bracket is fixedly connected to the left side of the pulverizing cylinder, and a servo motor is fixedly connected to the inner wall of the square bracket. This invention utilizes the servo motor to rotate a rotating shaft, which in turn rotates a connecting rod and a grinding roller. The grinding roller grinds the grain products inside the circular cylinder, and the rotation of the circular collar and pulverizing blades further pulverizes the grains. By combining the grinding of the grinding roller with the cutting action of the pulverizing blades, pulverization and grinding are performed simultaneously, enabling rapid and uniform pulverization of grain product samples. This achieves efficient pulverization and ensures that the processed grain products have more uniform and finer particles.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: The above-mentioned device utilizes the grinding of the grinding roller and the cutting and crushing of the crushing blade through the cooperation of the rotating shaft, connecting rod, grinding roller, circular collar and crushing blade. However, the grinding roller and crushing blade are both set horizontally, which makes it difficult for the grains crushed by the grinding roller and crushing blade to mix easily, that is, the grinding roller and crushing blade cannot be directly cooperated. Summary of the Invention

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the grinding roller and the crushing blade cannot be directly matched. To this end, we propose a grain sample crushing and processing device to prevent clogging.

[0006] To achieve the above objectives, this application adopts the following technical solution: a grain sample crushing and processing device for preventing clogging, comprising: an outer cylinder of the device, a crushing component disposed inside the outer cylinder of the device, and a filter component disposed inside the outer cylinder of the device;

[0007] The pulverizing assembly includes a pulverizing inner cylinder and a grinding cylinder. The pulverizing inner cylinder is fixedly installed at the center of the top end inside the outer cylinder of the equipment, and the grinding cylinder is fixedly installed at the center of the bottom end inside the outer cylinder of the equipment.

A filter screen is movably arranged inside the outer cylinder of the equipment. A central cover is fixedly installed on the outer side wall of the top of the filter screen. Several fixing blocks are fixedly installed on the outer side wall of the central cover. The fixing blocks correspond one-to-one with the several pairs of fixing plates, and the fixing blocks are arranged between the corresponding pairs of fixing plates.

[0010] Preferably, a fixing rod is fixedly installed between several pairs of fixing plates, a fixing block is slidably sleeved on the fixing rod, a functional spring is sleeved on the fixing rod, the functional spring is elastically connected between the bottom surface of the fixing block and the inner side wall of the fixing plate, the bottom end of the crushing inner cylinder is set inside the collection hood, and the outer diameter of the filter screen is smaller than the inner diameter of the top of the feed hopper.

The bottom of the outer cylinder is connected to a discharge valve pipe, which is connected to the grinding cylinder.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In this invention, grains enter the inner crushing cylinder through several feed inlets. A drive motor drives a rotating rod to rotate, causing the crushing blades to initially crush the grains. The initially crushed grains are then filtered through a filter screen. The filtered material enters the grinding cylinder through a feed hopper. The rotating rod drives the grinding steps to rotate via a fixed truncated cone, grinding the initially crushed grains to achieve fine grinding.

The fixed block slides on the fixed rod, compressing the functional spring. Under the reaction force of the functional spring, a certain vibration is generated on the filter screen, which avoids clogging of the filter screen. Attached Figure Description
