Description

Technical Field

[0001] This utility model relates to the technical field of soybean food processing, and in particular to a grinding device. This utility model also relates to a soybean pulverizer including the above-mentioned grinding device. Background Technology

[0002] A soybean grinder is a mechanical device specifically designed for crushing and grinding soybeans and other legume raw materials. It can efficiently transform materials into fine particles or powder through mechanical force. Its main structure consists of a feeding device, a grinding device, a power unit, and a screen control system. The grinding device typically contains rotating blades, hammers, or grinding discs. The power system is usually provided by an electric motor or diesel engine. The screen is used to adjust the fineness of the ground particles. Its core principle relies on the impact force, shearing force generated by high-speed rotating components, and the friction between materials to achieve the grinding and crushing of soybeans.

[0003] Depending on the working principle of the grinding device, soybean grinders can be divided into several types, including hammer mills, blade mills, disc mills, and air jet mills. Among them, disc mill soybean grinders produce uniform and fine particles and are mainly used in food processing such as soybean flour and soy sauce production, and in feed manufacturing such as soybean meal processing. However, due to the small particle size of the finished product and the high moisture content of the raw material, clumping may occur, leading to uneven discharge or even blockage of the discharge port. This phenomenon not only pollutes the workshop environment and poses potential risks to the health of operators, but also directly affects the production efficiency of soybean grinding operations.

[0004] Based on the above existing technologies, it can be seen that when processing raw materials with high moisture content, the disc-type soybean grinder is prone to material clumping and clogging the discharge port. Utility Model Content

[0005] In view of this, the present invention aims to provide a grinding device and a soybean crusher to solve the problem of material clumping and clogging at the discharge port, thereby improving the overall efficiency of soybean crushing operations and reducing environmental pollution to the workshop and potential health risks to operators.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A grinding apparatus includes a frame, which is vertically mounted on a horizontal ground;

[0008] The grinding box is fixedly installed on the top of the frame;

[0009] The main spindle is rotatably mounted on the grinding box in a horizontal direction;

[0010] The drive motor is fixedly mounted on the top of the frame and is connected to one end of the main shaft via a belt drive.

[0011] The cutter head is sleeved on the end of the spindle away from the drive motor and is located inside the grinding box;

[0012] A collection box is mounted on the frame, located below the grinding chamber;

[0013] The connecting plate is connected to the collection box at one end and extends to the bottom of the main shaft near the drive motor at the other end.

[0014] Furthermore, the spindle includes a shaft body, which is rotatably mounted on the grinding box;

[0015] A cam is fitted onto the end of the shaft.

[0016] A pulley is sleeved on the end of the shaft and is connected to the drive motor via belt drive.

[0017] A bushing is fitted onto the shaft body and is fixedly connected to the grinding box.

[0018] Furthermore, the grinding box includes an outer shell, which is fixedly mounted on the frame;

[0019] The screen is fixedly installed inside the outer casing;

[0020] The toothed disc is fixedly mounted on the outer casing and located inside the screen.

[0021] The toothed ring is fixedly mounted on the toothed disc and located inside the screen.

[0022] Furthermore, the toothed rings are constructed as multiple rings with different diameters distributed around the same center, and the cross-section of the cutter head end of the cutter disc is an "I" shape that fits the distribution of the multiple toothed rings.

[0023] Furthermore, multiple sets of connecting rods are vertically arranged between the screen and the outer casing.

[0024] Furthermore, it also includes a hopper with an open top and a bottom that communicates with the interior of the outer casing.

[0025] Furthermore, multiple flexible connection parts are provided between the collection box and the frame.

[0026] Furthermore, a discharge door is provided on the side wall of the collection box.

[0027] The grinding device of this invention comprises a frame, grinding box, main shaft, drive motor, cutter disc, collection box, and connecting plate. The frame supports and limits the installation of the other components. The grinding box serves as a container for crushing and sieving soybeans. The torque generated by the drive motor is transmitted to the cutter disc via the main shaft, causing the cutter disc to rotate within the collection box, thus achieving the grinding and pulverization of soybeans. The connecting plate, connected to the collection box at one end, extends below the end of the main shaft and generates periodic vibrations under the rotation of the main shaft. This vibration is transmitted to the side wall at the connection point with the collection box, below the discharge end of the grinding box. This vibration reduces material agglomeration and blockage, as well as uneven feeding, thereby improving the overall efficiency of soybean grinding operations and reducing environmental pollution and potential health risks to operators.

[0028] Secondly, the spindle is designed as a structure consisting of a shaft body, a cam, a pulley, and a bushing. The shaft body is the main structure of the spindle. The cam, mounted at one end of the shaft body, periodically presses against the connecting plate as the shaft body rotates, causing the connecting plate to vibrate periodically. The pulley mounted on the shaft body is connected to the power output shaft of the drive motor via belt drive, realizing torque transmission. The bushing, fixedly connected to the outer surface of the grinding chamber side wall, provides dust protection for the shaft body.

[0029] By designing the grinding chamber as a structure consisting of an outer shell, a screen, a toothed disc, and a toothed ring, the outer shell serves to limit the installation of the other structural components and acts as a container for soybean crushing. The screen filters the crushed soybean powder, controlling the particle size of the finished product. The composite structure of the toothed disc and toothed ring works in conjunction with the cutter disc to rub, compress, and crush the soybeans. A connecting rod between the screen and the inner wall of the outer shell increases the structural stability of the screen and improves its resistance to compression. A multi-layered concentric structure of the toothed ring further enhances the efficiency of soybean grinding and crushing.

[0030] Furthermore, installing an open-top hopper at the feed end of the grinding chamber improves the ease of feeding and increases the overall processing efficiency of soybean grinding. By incorporating multiple flexible connections between the collection box and the frame, some vibration transmission from the collection box to the frame is reduced, thus lowering operating noise.

[0031] This utility model also includes a soybean grinder, which uses the grinding device described above.

[0032] The grinding device in this invention achieves the same technical effect as the existing grinding device in a soybean crusher, and will not be described again here. Attached Figure Description

The utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] The following will refer to the appendix. Figure 1 To be continued Figure 3 The present invention will be described in detail with reference to the embodiments.

[0044] Example 1

[0045] This embodiment relates to a grinding device that can alleviate the phenomenon of material clumping and clogging at the discharge port, thereby improving the overall efficiency of soybean grinding operations and reducing environmental pollution to the workshop and potential health risks to operators.

[0046] In terms of overall structure, refer to Figure 1The grinding device in this embodiment includes a frame 1, a grinding box 2, a main shaft 3, a drive motor 4, a cutter head 5, a collection box 6, and a connecting plate 7. The frame 1 can be a metal frame welded from galvanized hollow square steel. The frame 1 is fixedly mounted on a horizontal surface, and the grinding box 2 is fixedly mounted on top of the frame 1 by bolts. The main shaft 3 can be a cylindrical metal shaft with its axis oriented horizontally and rotatably mounted on the grinding box 2. The drive motor 4 is mounted on top of the frame 1 by bolts, and its power output shaft is connected to one end of the main shaft 3 via a belt to transmit torque. The cutter head 5 is fitted onto one end of the main shaft 3 opposite to the drive motor 4. The collection box 6 can be a hollow metal box with an open top. The open top of the collection box 6 is opposite to the discharge end at the bottom of the collection box 6. One end of the connecting plate 7 is fixedly connected to the side wall of the collection box 6 by welding, and the other end extends vertically to the bottom of the main shaft 3 near the drive motor 4.

[0047] By configuring the grinding device into a structure consisting of a frame 1, a grinding box 2, a main shaft 3, a drive motor 4, a cutter disc 5, a collection box 6, and a connecting plate 7, the frame 1 provides support and limits the installation of the other structural components. The grinding box 2 serves as a container for crushing and sieving soybeans. The torque generated by the rotation of the drive motor 4 is transmitted to the cutter disc 5 through the main shaft 3, causing the cutter disc 5 to rotate within the collection box 6, thereby achieving the grinding and pulverization of soybeans. The connecting plate 7, connected at one end to the collection box 6, extends to the lower end of the main shaft 3. It generates periodic vibrations under the rotation of the main shaft 3 and transmits these vibrations to the side wall at the connection point with the collection box 6, i.e., below the discharge end of the grinding box 2. This vibration reduces material agglomeration and blockage, as well as uneven feeding, thereby improving the overall efficiency of soybean pulverization operations and reducing environmental pollution and potential health risks to operators.

[0048] Reference Figure 1 and Figure 3 The main shaft 3 includes a shaft body 301, a cam 302, a pulley 303, and a bushing 304. The cam 302 and pulley 303 are both fitted onto the shaft body 301 and rotate together with it. The bushing 304 is fitted onto the shaft body 301, and one end is fixedly connected to the outer surface of the side wall of the grinding box 2.

[0049] By configuring the main shaft 3 into a structure consisting of a shaft body 301, a cam 302, a pulley 303, and a bushing 304, the shaft body 301 forms the main structure of the main shaft 3. The cam 302, mounted on one end of the shaft body 301, periodically presses against the connecting plate 7 as the shaft body 301 rotates, causing the connecting plate 7 to vibrate periodically. The pulley 303, mounted on the shaft body 301, is connected to the power output shaft of the drive motor 4 via belt drive, thus transmitting torque. The bushing 304, fixedly connected to the outer surface of the side wall of the grinding chamber 2, provides dust protection for the shaft body 301.

[0050] Reference Figure 1 and Figure 2 The grinding box 2 includes an outer shell 201, a screen 202, a toothed disc 203, and a toothed ring 204. The outer shell 201 can be a cylindrical hollow metal box with its axis aligned horizontally. The outer shell 201 consists of a cylindrical cast iron body and circular front and rear end caps. The screen 202 is fixedly installed inside the outer shell 201 and can be a cylindrical screen coaxial with the outer shell 201. Multiple sets of connecting rods are perpendicularly arranged between the screen 202 and the outer shell 201 along a direction parallel to its own axis. The toothed disc 203 and toothed ring 204 are both installed inside the screen 202. The toothed disc 203 is parallel to the front and rear end caps of the grinding box 2, and the toothed ring 204 is concentric with the toothed disc 203. Both the toothed disc 203 and toothed ring 204 are fixed inside the grinding box 2. The toothed ring 204 can be composed of multiple ring-shaped structures with the same center but different radii. The cross-sectional shape of the cutter head 5 is constructed to fit the distribution of multiple toothed rings 204 in an "I" shape.

[0051] By configuring the grinding chamber 2 into a structure consisting of an outer shell 201, a screen 202, a toothed disc 203, and a toothed ring 204, the outer shell 201 serves to limit the installation of other structural components and acts as a container for soybean crushing. The screen 202 filters the crushed soybean powder, controlling the particle size of the finished product. The composite structure of the toothed disc 203 and the toothed ring 204 works in conjunction with the cutter disc 5 to rub, compress, and crush the soybeans. A connecting rod between the screen 202 and the inner wall of the outer shell 201 increases the structural stability of the screen 202 and improves its resistance to compression. A multi-layered concentric structure of the toothed ring 204 further enhances the efficiency of soybean grinding and crushing.

[0052] Reference Figure 1 and Figure 2 A hopper 8 is installed on the top of the grinding box 2. The hopper 8 can be a metal shell with an open top and a bottom that communicates with the interior of the outer casing 201. Multiple flexible connections are provided between the collection box 6 and the frame 1 to achieve flexible support. The flexible connections can be rigid springs or solid cylindrical rubber pads.

[0053] By installing a hopper 8 with an open top at the feed end of the grinding box 2, the convenience of the feeding process can be improved, and the overall processing efficiency of soybean grinding can be increased. By setting multiple flexible connections between the collection box 6 and the frame 1, some vibration transmission from the collection box 6 to the frame 1 can be reduced, thus lowering operating noise.
