Description

Technical Field

[0001] The invention relates to the technical field of grain crushers, in particular to a millet crusher for processing agricultural products. Background Art

[0002] In the field of agricultural product processing, millet crushing is a key process for preparing basic raw materials such as millet flour and broken rice. It is widely used in food processing, nutritional products and deep processing industries. With the increasing demand for refined and standardized millet crushing in industrial processing, it is necessary to develop a special crushing equipment with efficient crushing function. Therefore, we propose a millet crusher for agricultural product processing.

[0003] The prior art also has the following defects during use: 1. Millet crushers in the existing technology rely on equipment such as stone mills and roller crushers to achieve particle crushing through the principle of extrusion and grinding. However, millet particles have the characteristics of small particle size and high cortex toughness. Single extrusion crushing easily leads to uneven particle size, which not only causes starch loss but also increases the cost of subsequent screening processes. 2. The millet crusher in the prior art has a relatively simple function and only has the function of crushing millet and other grains. After the millet is crushed, since the surface of the millet has a layer of husk, the husk in the millet particles needs to be screened after crushing. The traditional millet crusher does not have a husk separation structure and needs to add independent screening equipment later, which not only increases the millet processing process, but also consumes the millet processing time and reduces the efficiency of millet processing.

[0004] In view of this, we propose a millet crusher for agricultural product processing to solve the existing problems. Summary of the Invention

[0012] Preferably, a support seat is fixedly installed on the bottom of the box, and a material guide plate is fixedly installed on the left side of the bottom of the box. The material guide plate is a plate-like structure installed at an angle. A top plate is fixedly installed on the top of the box, and a controller is fixedly installed on the top of the top plate.

[0013] Preferably, a grid plate is fixedly installed on the bottom of the box, and a plurality of strip grooves are opened inside the grid plate.

The Laillo triangle-shaped grinding wheel cooperates with the lower shell to grind the millet between the grinding wheel and the lower shell, so that the millet is ground into fine particles and the husk on the surface of the millet is separated. The Laillo triangle-shaped grinding wheel is a variable-diameter disc, so it can apply pressure from small to large on the millet when it rotates, so that the millet is crushed when it is intermittently under pressure. Compared with traditional millet crushers, it can prevent the millet from getting stuck in the gap and unable to be effectively crushed.

[0018] 3. The present invention installs a mounting plate inside the box to divide the space inside the box, so that the air guide box can simultaneously suck the air inside the space above and below the mounting plate, causing the air to move horizontally inside the box. As a result, when the millet is discharged, the light husk is introduced into the box, while the heavier millet falls onto the guide plate and is guided to a designated position for collection. After the light husk enters the box, it moves along a parabolic trajectory and falls from the mesh plate, thereby realizing the separation of the millet and the husk, thereby increasing the functionality of the device.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1, as Figures 1-12As shown, the present invention proposes a millet crusher for agricultural product processing, comprising a lower housing 1, a housing 2, a mounting plate 3 and a processing assembly 5. The housing 2 is a metal frame structure, and two sets of baffles 203 are installed on the front and rear sides of the housing 2. The housing 2 can provide installation locations for surrounding components. The baffles 203 can shield the front and rear sides of the housing 2 and limit the flow direction of air inside the housing 2, so that the air flows horizontally from left to right inside the housing 2, driving the husks in the millet into the housing 2, and also allowing air to flow around the motor 302 to achieve continuous heat dissipation of the motor 302. The top of the coupling 301 is fixedly connected to the box body 2, and the output shaft of the motor 302 faces left. The output shaft of the motor 302 is fixedly installed with a coupling 301. The top of the coupling 301 is fixedly connected to the box body 2. The mounting plate 3 can provide a mounting position for the surrounding components and separate the space inside the box body 2 so that the air inside the box body 2 is drawn into the interior of the air guide box 4 from the top and bottom of the mounting plate 3 respectively. The motor 302 adopts the YE4-100KW type. The motor 302 is connected to the controller 205 through a cable. After the controller 205 is connected to an external power supply, the motor 302 is powered, so that the motor 302 rotates, driving the processing assembly 5 to rotate inside the upper shell 102 and the lower shell 1 to grind the millet. The coupling 301 can connect the output shaft of the motor 302 with the processing assembly 5, so that the motor 302 drives the processing assembly 5 to rotate synchronously; An air guide box 4 is fixedly mounted on the right side of the box 2, and two sets of fans 401 are fixedly mounted on the right side of the air guide box 4. The air guide box 4 can provide a mounting location for surrounding components and guide the air inside the box 2 to flow into the air guide box 4. The fans 401 are DPT12-45B type. When powered on, the fans 401 can suck the air inside the air guide box 4, so that the air inside the box 2 flows toward the air guide box 4. The left side of the box body 2 is equipped with a lower shell 1 through a support frame 106, and the top of the lower shell 1 is equipped with an upper shell 102 through bolts. The upper shell 102 and the lower shell 1 are both semicircular structures, and the inner cavities of the upper shell 102 and the lower shell 1 are combined to form a circular cavity. The lower shell 1 and the upper shell 102 cooperate to form a circular cavity, which then cooperates with the processing component 5 to make the millet enter the upper shell 102 and the lower shell 1, and gather at the bottom of the lower shell 1. The processing component 5 pushes the millet and the lower shell 1 to be squeezed, thereby achieving the millet crushing. The upper shell 102 and the lower shell 1 are internally rotatably installed with a processing assembly 5, and the right side of the processing assembly 5 extends out of the upper shell 102 and the lower shell 1 and is fixedly connected to the coupling 301. The processing assembly 5 is connected to the coupling 301, so that when the motor 302 rotates, it can drive the processing assembly 5 to rotate synchronously, so that the processing assembly 5 cooperates with the lower shell 1 to crush the millet inside the upper shell 102 and the lower shell 1.

[0023] Furthermore, the processing component 5 includes a grinding disc 501, and a central shaft 502 is fixedly installed at the central position of the grinding disc 501. The left end of the central shaft 502 is connected to the upper shell 102 and the lower shell 1 through a ball bearing, and the right end of the central shaft 502 extends out of the upper shell 102 and the lower shell 1 and is fixedly connected to the coupling 301. The grinding disc 501 can provide an installation position for the surrounding components and drive the surrounding components to rotate synchronously, so that the millet can be crushed by cooperating with the grinding disc 501 and the lower shell 1. The central shaft 502 can limit the grinding disc 501, and by connecting the central shaft 502 to the coupling 301, the motor 302 can drive the central shaft 502 to rotate, thereby driving the grinding disc 501 and the surrounding components to rotate synchronously.

[0024] Furthermore, two mounting grooves 503 are symmetrically arranged inside the grinding disc 501. Limiting frames 504 are fixedly installed on both sides of the mounting grooves 503. A slide groove 506 is provided on the inner side of the limiting frame 504. A scraper 505 is installed inside the mounting groove 503 through two springs 507. Limiting shafts 508 are installed on both sides of the scraper 505, and the limiting shafts 508 are engaged with the slide grooves 506. The mounting groove 503 can provide an installation position for the internal components, and the limiting frame 504 can cooperate with the limiting shaft 508 to limit the scraper 505. The sliding groove 506 is used to limit the moving direction of the scraper 505 inside the installation groove 503, and the scraper 505 is elastically connected by the spring 507, so that when the grinding disc 501 rotates, different centrifugal forces are applied to the scraper 505 inside the grinding disc 501 through different rotation speeds, and the length of the scraper 505 extending out of the grinding disc 501 is controlled by the centrifugal force and the elastic force applied by the spring 507, so that the scraper 505 contacts the millet to different degrees, and then when the grinding disc 501 rotates, the scraper 505 and the millet are improved together. The effect of crushing the millet is improved.

[0025] Furthermore, a feed hole is provided at the top of the upper shell 102, and a lower hopper 101 is fixedly installed inside the feed hole, a discharge hole is provided at the bottom of the lower shell 1, a discharge valve 103 is fixedly installed at the bottom of the lower shell 1, and the discharge valve 103 is connected to the discharge hole, and a diffusion disk 104 is fixedly installed at the bottom of the discharge valve 103. The diffusion disk 104 is a fan-shaped structure with a plurality of flow channels arranged inside, and the tops of the plurality of flow channels are all connected to the bottom of the discharge valve 103. The lower hopper 101 can guide the millet into the interior of the upper shell 102, and then guide it to the lower shell 1 through the upper shell 102, so that the millet can be crushed by the lower shell 1 and the grinding disc 501. The discharge valve 103 can control the switch of the discharge hole so that the millet inside the lower shell 1 can be discharged after the millet is crushed. The diffusion disk 104 can guide the processed millet so that the millet is discharged over a larger range, so as to separate the millet particles and the husk.

[0026] Furthermore, two slides 105 are fixedly installed on the right side of the upper shell 102 and the lower shell 1. The two slides 105 on the right side of the lower shell 1 are connected to the support frame 106. A connecting rod 107 is slidably installed in the two slides 105 on the right side of the upper shell 102, and the connecting rod 107 is fixedly connected to the box body 2. A threaded rod 108 is vertically installed inside the slide 105, and the threaded rod 108 passes through the connecting rod 107 and the slide 105. The slide 105 can be connected to the connecting rod 107 and the support frame 106 respectively. The connection between the slide 105 and the support frame 106 can limit the lower shell 1, and when the threaded rod 108 is rotated to adjust the installation height of the upper shell 102, the installation height of the lower shell 1 can be driven to adjust the distance between the inner wall of the lower shell 1 and the edge of the grinding disc 501, so as to achieve different degrees of crushing of millet.

[0027] Furthermore, a support seat 202 is fixedly installed at the bottom of the box body 2, and a material guide plate 201 is fixedly installed on the left side of the bottom of the box body 2. The material guide plate 201 is a plate-like structure installed at an angle. A top plate 204 is fixedly installed on the top of the box body 2, and a controller 205 is fixedly installed on the top of the top plate 204. The support seat 202 can support the box body 2, thereby ensuring the stability of the device during operation. The material guide plate 201 can guide the processed millet particles so as to guide the millet particles to a designated position, which is convenient for centralized collection of the millet particles. The top plate 204 can provide an installation position for the controller 205. The controller 205 can be connected to an external power supply through a cable and electrically connected to other electronic components through a cable so as to control other electronic components to work in coordination.

[0028] Furthermore, a mesh plate 206 is fixedly installed at the bottom of the box 2, and a number of strip grooves are opened inside the mesh plate 206. The mesh plate 206 can guide the husk, and after the husk falls on the mesh plate 206, it penetrates the mesh plate 206 and falls to the bottom of the box 2, separating the husk from the millet particles.

[0029] Furthermore, a first mesh panel 402 is fixedly installed on the left side of the air guide box 4 between the top of the box body 2 and the mounting plate 3, and a second mesh panel 403 is fixedly installed on the left side of the air guide box 4 between the bottom of the box body 2 and the mounting plate 3. The first mesh panel 402 and the second mesh panel 403 can respectively isolate the box body 2 and the air guide box 4 to prevent large objects from being sucked into the air guide box 4 and causing poor air flow.

[0030] Furthermore, a plurality of ventilation holes are provided inside the second mesh plate 403, and the ventilation holes extend obliquely upward from left to right. Air holes are provided on the right side of the air guide box 4 at the installation positions of the two sets of fans 401. The plurality of ventilation holes obliquely arranged inside the second mesh plate 403 can allow the air inside the box body 2 to enter the air guide box 4, and can prevent the skin shell from being sucked into the interior of the air guide box 4 from the airflow from the mesh plate 206.

[0031] Working principle: After the device is assembled, the controller 205 controls the motor 302 and the fan 401 to work. The fan 401 runs at the same time, and the air inside the box 2 is sucked into the air guide box 4, so that the air continues to flow from the left side of the box 2 to the air guide box 4. After the motor 302 is powered on, it rotates and drives the processing component 5 to rotate, and the millet is put into the upper shell 102 from the lower hopper 101. The millet is driven by the processing component 5 to move back and forth inside the lower shell 1 and exert pressure on the millet to crush the millet. When the motor 302 drives the processing component 5 to move in different directions, the millet is crushed. When the speed rotates, affected by the centrifugal force, the scraper 505 extends from the mounting groove 503 to varying degrees and contacts the millet, thereby improving the millet crushing effect of the processing component 5. The crushed millet and the peeled husk are discharged from the discharge valve 103 to the diffusion disk 104. The diffusion disk 104 expands the diffusion area of the millet and the husk, so that the heavier millet falls onto the guide plate 201 for discharge, and the lighter husk is driven by the airflow into the box body 2, passes through the mesh plate 206 and falls to the bottom of the box body 2, completing the millet crushing and husk separation.

[0032] Example 2, as Figure 13-14As shown, the difference from the above embodiment is that the grinding wheel 501 in this embodiment is a disc in the shape of a Lello triangle, and the grinding wheel 501 is set at a distance of two to four millimeters from the lowest position of the inner wall of the lower shell 1. The grinding wheel 501 designed in the shape of a Lello triangle is a disc with a variable diameter due to the different distances from its edge to the center of the circle. Therefore, when the grinding wheel 501 rotates, the distance between the edge of the grinding wheel 501 and the inner wall of the lower shell 1 will change, and the pressure applied to the millet will also change accordingly. When the millet is crushed, intermittent pressure from small to large can be applied to the millet, and the sharp corners of the grinding wheel 501 are used to drive the millet to move, and rub against the inside of the lower shell 1, thereby improving the crushing effect of the device on the millet.

[0033] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
