Description

Technical Field

[0001] This utility model relates to the technical field of grain crushing equipment, specifically to an intermittent grain crusher. Background Technology

[0002] In the grain processing industry, grain crushing is a crucial step in transforming raw grains into various foods, feeds, or industrial raw materials. Crushing increases the total surface area of ​​grain particles, improves their solubility in animal digestive fluids, and thus enhances the digestibility of feed. At the same time, adjusting particle size reduces the energy consumption of livestock and poultry during chewing, making subsequent processes such as feed transportation, storage, mixing, and pelleting more convenient and efficient.

[0003] In scenarios requiring precise particle size distribution, such as sample preparation for mycotoxin testing, commonly used small electric grain grinders often suffer from low efficiency due to their small feed and receiving hopper capacities. This necessitates frequent sample addition to the feed hopper and removal of the receiving hopper for emptying, resulting in significant time consumption and extremely low work efficiency. Directly replacing the feed hopper with a larger capacity one can cause feed blockages, while removing the receiving hopper for direct sample collection can lead to sample spillage and dust overflow, affecting test results and contaminating the laboratory environment.

[0004] Meanwhile, after the materials are crushed, existing equipment often cannot automatically separate materials of different particle sizes. For materials with larger particle sizes that do not meet the crushing requirements, the subsequent selection and re-crushing operations are cumbersome, increasing production costs and labor intensity. Furthermore, continuous feeding crushers are prone to clogging when processing special materials such as granular medicinal materials due to continuous material input, reducing the crushing effect. Utility Model Content

[0005] Technical problems to be solved

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a grain intermittent crusher, which can effectively solve the problems in the existing technology.

[0007] Technical solution

[0008] This utility model provides an intermittent grain crusher, including a support frame, a box fixed in the middle of the support frame, the bottom of the box being in communication with the crushing components, and an intermittent feeding device provided inside the box. The intermittent feeding device includes a feeding port, a drive motor disposed in the feeding port, and a release plate. The feeding port has a feeding opening in the middle, and a connecting ring is fixed at the bottom end of the feeding port. The middle part of the release plate is connected to a connecting shaft and sleeved thereon. An L-shaped spacer plate is fixed in the middle of the release plate. The output end of the drive motor is fixedly connected to an arc plate, and a support plate is fixedly connected at the bottom end of the arc plate. The bottom end of the support plate is inserted into the gap between the spacers, and a contact plate is fixed at the top end of the release plate. The inner side of the contact plate contacts the outer wall of the arc plate.

[0009] Furthermore, multiple sets of the spacer plates and contact plates are fixed at equal intervals on the top of the release plate, and the spacer plates are spacer plates with rounded corners and L-shapes.

[0010] Furthermore, the drive motor is fixed on the feeding box, and the bottom end of the connecting shaft is fixedly connected to the disc structure, while the top end of the disc structure is fixedly connected to the release plate.

[0011] Furthermore, the inner wall of the contact plate is an arc-shaped structure, and the arc-shaped plate is also an arc-shaped structure, and there is an included angle between the arc-shaped plate and the support plate.

[0012] Furthermore, the bottom dimension of the support plate is adapted to the inner diameter dimension of the partition plate.

[0013] Furthermore, the crushing component is provided with a structure having a crushing function, and its power end is connected to the output end of the drive motor.

[0014] Beneficial effects

[0015] This invention utilizes an intermittent feeding device. A drive motor within the device rotates the bottom arc-shaped plate structure and support plate. During this process, the arc-shaped plate contacts the inner wall of the contact plate, and the support plate structure rotates along the groove between the intermittent plates, driving the release plate to rotate. Therefore, grain is fed downwards through the feeding port and connecting ring. The release plate, rotating within a specified time, exposes holes that contact the connecting ring, allowing the grain to be fed downwards from the bottom into the crushing assembly, completing the intermittent crushing function. This intermittent feeding mechanism precisely controls the amount of material input and the crushing rhythm, preventing equipment blockage due to excessive material in a short period, ensuring a smooth and efficient crushing process. Compared to traditional continuous crushers, the crushing efficiency can be increased by more than 30%. Furthermore, the optimized crushing chamber design and working mode effectively prevent material from entering equipment gaps, reducing material residue and waste. It also avoids frequent manual material collection, saving labor and time costs and improving economic efficiency. Attached Figure Description

[0025] Example: A grain intermittent pulverizer, as shown in the attached document. Figure 1 - Appendix Figure 5The system includes a support 1, a box 2 fixed in the middle of the support 1, the bottom of the box 2 being in communication with the crushing component 4, and an interval feeding device 5 provided inside the box 2. The interval feeding device 5 includes a feeding port 51, a drive motor 52 and a release plate 54 disposed in the feeding port 51.

The inner side of the contact plate 542 contacts the outer wall of the arc plate 521.

[0026] Multiple sets of spacer plates 541 and contact plates 542 are fixed at equal intervals on the top of the release plate 54. The spacer plates 541 are spacer plates with rounded corners and L-shapes. Through the set interval feeding device 5, the bottom arc plate 521 structure and support plate 522 are driven to rotate by the drive motor 52 therein.

Therefore, the grain is passed downward through the feed port 51 and the connecting ring 511. The exposed hole of the release plate 54, which rotates within a specified time, contacts the connecting ring 511, so the grain can be passed downward from the bottom and enter the crushing component 4 to complete the intermittent crushing function. The intermittent feeding mechanism can accurately control the amount of material input and the crushing rhythm, avoid equipment blockage due to excessive material in a short period of time, and ensure that the crushing process is smooth and efficient.

[0027] The drive motor 52 is fixed on the feeding box 21, and the bottom end of the connecting shaft 53 is fixedly connected to the disc structure, while the top end of the disc structure is fixedly connected to the release plate 54. The inner wall of the contact plate 542 is an arc-shaped structure, and the arc plate 521 is also an arc-shaped structure, with an included angle between the arc plate 521 and the support plate 522. The bottom dimension of the support plate 522 is adapted to the inner diameter dimension of the partition plate 541. The crushing component 4 is equipped with a structure with crushing function, and its power end is connected to the output end of the drive motor 3. The crushing efficiency can be increased by more than 30%, and the optimized crushing chamber design and working mode can effectively prevent materials from entering the equipment gaps, reduce material residue and waste, and avoid frequent manual material collection, saving labor and time costs and improving economic benefits.
