Description

Technical Field

[0001] This utility model relates to the technical field of rice milling and pulverizing machines, and in particular to a rice milling and pulverizing machine shell and a rice milling and pulverizing combination machine. Background Technology

[0002] Rice milling machines and crushers are grain processing and material crushing machines used by rural households. To facilitate the combination of rice milling machines and crushers into one machine, the applicant's earlier patent application, patent number CN214051744U "Sheet Metal Formed Shell Rice Milling and Crushing Combination Machine", provides a sheet metal formed shell rice milling and crushing combination machine, including a shell, hopper, hopper seat, rice milling component 111, rice sieve, rice discharge adjustment mechanism, crusher bearing body component, crushing screen component, crushing gate component, crusher inclined hopper, motor, frame, and protective cover. The shell is a sheet metal formed steel structure. The upper end of the shell has a rice milling inlet. The hopper seat is fixed above the rice milling inlet. The interior of the shell forms a rice milling roller component mounting cavity, a crusher bearing body component mounting cavity, and a crushing screen mounting cavity. The crusher bearing body component mounting cavity is located on the side of the rice milling roller component mounting cavity. The crushing valve assembly is a sheet metal steel structure, which is connected to the housing by hinges. The crushing feed inlet is provided on the top and side of the valve. This sheet metal rice milling and crushing combination machine changes the structure of the base so that the housing can be flexibly unfolded. It is small in size and light in weight, easy to package and transport, and has low manufacturing cost and low operation. It is also simple to operate. The housing used can be referenced from the sheet metal molded housing of the rice milling and pulverizing combination machine provided in patent number CN214051743U "Sheet Metal Molded Rice Milling and Pulverizing Combination Machine Housing". This housing includes a rice milling fixed housing, a pulverizing fixed housing, and a movable housing. The rice milling fixed housing, the pulverizing fixed housing, and the movable housing are sheet metal molded components. The pulverizing fixed housing is fixed to the rice milling fixed housing as a whole. The inside of the rice milling fixed housing is the rice milling component mounting cavity, and the inside of the pulverizing fixed housing is the pulverizing rotor mounting cavity and the screen assembly mounting cavity. The movable housing is connected to the pulverizing feed inlet. The upper end of the housing has a rice milling feed inlet, and the bucket is fixed above the feed inlet. The pulverizing rotor mounting cavity is located on the side of the rice milling component mounting cavity, forming a left-right structure. The movable housing is movably connected by hinges. The movable housing has a pulverizing feed inlet A and a pulverizing feed inlet B on the upper and side, respectively.

[0003] In practical applications, the aforementioned sheet metal forming shell rice milling and pulverizing combination machine is usually mounted on a frame. Specifically, for example... Figure 1As shown, the motor driving the rice milling and pulverizing combination machine is mounted on the frame and is connected to the rice milling bearing assembly and the pulverizing bearing body assembly via a belt drive assembly. The discharge end of the rice milling fixed shell includes a rice bran outlet and a rice outlet connected to the rice discharge adjustment structure. The pulverized material in the pulverizing fixed shell is discharged directly from the lower opening of the pulverizing fixed shell. Typically, a discharge hopper with an opening adapted to the lower opening of the pulverizing fixed shell is installed on the frame for discharge. However, since the sheet metal-formed rice milling and pulverizing combination machine and the frame are assembled, during installation, the discharge hopper on the frame must be aligned with the lower opening of the pulverizing fixed shell before installation. During installation, due to the inherent errors in manual assembly and the fact that the pulverizing fixed shell and the discharge hopper on the frame are manufactured separately, there are also certain manufacturing defects. Errors prevent the hopper from ensuring a tight seal between the discharge hopper and the crushing housing. This is especially problematic in rural households where improper use and inadequate protection can lead to leaks due to loose connections and deformation after a period of time, impacting the surrounding environment. Furthermore, the finely ground material can cause these leaks, and if a large amount of flying material adheres to the transmission mechanism, it can interfere with the normal operation of the belt drive, reducing production efficiency. Additionally, the structure described in patent CN212576418U, "A Rice Milling and Crushing Combined Machine," places the discharge hopper directly below the housing. While this prevents leakage, it increases the housing's size and makes it irregularly shaped, hindering packaging and transportation. It also occupies space on the lower frame, affecting the installation of the motor and transmission mechanism. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a rice milling and pulverizing machine shell, mainly used for grain processing, so as to reduce material leakage and facilitate packaging and transportation.

[0005] This utility model provides a rice milling and pulverizing machine casing, comprising a sheet metal rice milling fixed casing, a pulverizing fixed casing, and a movable casing. The pulverizing fixed casing is fixed to one side of the rice milling fixed casing, and the movable casing is movably disposed on the side of the pulverizing fixed casing away from the rice milling fixed casing. The pulverizing fixed casing has a pulverizing rotor mounting cavity and a screen assembly mounting cavity, and the rice milling fixed casing has a rice milling assembly mounting cavity. A discharge port is opened on the side of the pulverizing fixed casing away from the rice milling fixed casing, and the interior of the pulverizing fixed casing houses the screen assembly. The discharge channel is located below the mounting cavity and is inclined. The discharge channel includes an arc-shaped section. One end of the arc-shaped section is fixedly connected to the side of the crushing and fixing housing near the rice milling and fixing housing. The other end extends into a straight section along the tangential direction. The straight section is fixedly connected to the lower end of the discharge port. The end of the discharge channel near the rice milling and fixing housing is higher than the end of the discharge channel near the discharge port. The width of the discharge channel is the same as the width of the screen assembly mounting cavity. The discharge hopper is located on the outer side of the crushing and fixing housing. The discharge hopper is arranged along the inclined direction of the discharge channel and is connected to the discharge port.

[0006] Furthermore, the discharge hopper is detachably connected to the crushing and fixing housing.

[0007] Furthermore, the movable housing is provided with a locking bolt for connecting with the crushing fixed housing, and the locking bolt passes through the movable housing and is threadedly connected to the crushing fixed housing.

[0008] In a preferred embodiment, the locking bolt comprises a straight rod section and a threaded section connected in sequence. The movable housing has a through hole penetrating the movable housing, and the crushing and fixing housing has a threaded hole corresponding to the through hole. The straight rod section passes through the through hole, and the threaded section is threadedly connected to the threaded hole.

[0009] Furthermore, the crushing and fixing housing is integrally formed with the rice milling and fixing housing. When the movable housing is connected to the crushing and fixing housing and the rice milling and fixing housing, the top surface of the movable housing is flush with the top surface of the crushing and fixing housing and the top surface of the rice milling and fixing housing.

[0010] This utility model also provides a rice milling and pulverizing combination machine that uses the above-mentioned rice milling and pulverizing machine shell to reduce material leakage. It also includes a frame, with the rice milling fixed shell and the pulverizing fixed shell detachably mounted on the top of the frame. A rice milling component is installed in the rice milling component mounting cavity, a pulverizing screen component is installed in the pulverizing screen mounting cavity, and a pulverizing rotor component is installed in the pulverizing rotor mounting cavity. The top of the rice milling fixed shell has a rice milling machine inlet, and the end face of the rice milling fixed shell has a rice outlet with a rice outlet adjustment mechanism. The top of the movable shell has a first pulverizing machine inlet, and the end face of the movable shell has a second pulverizing machine inlet. The outlet is located above the frame, and the bottom of the discharge hopper is higher than the frame. A motor is located below the frame, and the rice milling component and the pulverizing rotor component are connected to the motor via a drive system.

[0011] The beneficial effects of this utility model are as follows: a discharge port is opened on the side of the crushing fixed shell away from the rice milling fixed shell, and a discharge channel connected to the discharge port and located below the crushing rotor mounting cavity is set inside the crushing fixed shell. The discharge channel is inclinedly set inside the crushing fixed shell and is integrally set with the crushing fixed shell, which effectively avoids material leakage. Moreover, setting the discharge channel inside the crushing fixed shell effectively saves the space occupied by the rice milling shell, making the rice milling shell a regular cube, which is conducive to subsequent packaging and transportation. At the same time, the discharge port is set on one side of the crushing fixed shell, so that the discharge hopper and discharge channel will no longer occupy the internal space of the frame, providing more flexibility for the arrangement of other components such as motors and transmission devices, which is conducive to the subsequent assembly of the rice milling combination machine.

Detailed Implementation

[0020] The present invention will be further described below.

[0021] This utility model provides a rice milling and pulverizing machine shell, mainly used for grain processing. It includes a sheet metal rice milling fixed shell 1, a pulverizing fixed shell 2, and a movable shell 3. The pulverizing fixed shell 2 is fixed to one side of the rice milling fixed shell 1, and the movable shell 3 is movably disposed on the side of the pulverizing fixed shell 2 away from the rice milling fixed shell 1. The pulverizing fixed shell 2 has a pulverizing rotor mounting cavity 21 and a screen assembly mounting cavity 22. The rice milling fixed shell 1 has a rice milling assembly mounting cavity 11. The pulverizing fixed shell 2 has a discharge port 23 on the side away from the rice milling fixed shell 1. The interior of the pulverizing fixed shell 2 has a cavity located below the screen assembly mounting cavity 22. An inclined discharge channel 24 includes an arc-shaped segment 241. One end of the arc-shaped segment 241 is fixedly connected to the side of the crushing and fixing housing 2 near the rice milling fixing housing 1, and the other end extends into a straight segment 242 along the tangential direction. The straight segment 242 is fixedly connected to the lower end of the discharge port 23. The end of the discharge channel 24 near the rice milling fixing housing 1 is higher than the end of the discharge channel 24 near the discharge port 23. The width of the discharge channel 24 is the same as the width of the screen assembly mounting cavity 22. A discharge hopper 25 is provided on the outside of the crushing and fixing housing 2. The discharge hopper 25 is arranged along the inclined direction of the discharge channel 24 and is connected to the discharge port 23.

[0022] like Figures 2-7As shown, the outer shell of the rice milling and pulverizing machine includes a rice milling fixed shell 1, a pulverizing fixed shell 2, and a movable shell. All three shells are formed from sheet metal. The pulverizing fixed shell 2 is fixed to one side of the rice milling fixed shell 1, forming a left-right structure, which can be achieved by welding or integral molding. The movable shell 3 is movably positioned on the side of the pulverizing fixed shell 2 away from the rice milling fixed shell 1, and can be connected by a hinge 4. Inside the pulverizing fixed shell 2, there is a pulverizing rotor mounting cavity 21 and a screen assembly mounting cavity 22; inside the rice milling fixed shell 1, there is a rice milling assembly mounting cavity 11. This allows for the later assembly of corresponding components. The crushing rotor mounting cavity 21 is located on the side of the rice milling assembly mounting cavity 11, forming a left-right structure. The upper and side of the movable housing 3 are respectively provided with a first crushing inlet and a second crushing inlet. A discharge port 23 is provided on the side of the crushing fixed housing 2 away from the rice milling fixed housing 1 so that the material in the crushing fixed housing 2 can be discharged from the discharge port 23. Inside the crushing fixed housing 2, there is a discharge channel 24 located below the crushing rotor mounting cavity 21. The discharge channel 24 is inclined along the length of the crushing fixed housing 2 and is arranged inside the crushing fixed housing 2 to discharge the material. The discharge channel 24 is located below the crushing rotor mounting cavity 21, enabling timely material transfer without affecting the normal operation of the crushing rotor. The discharge channel 24 includes an arc-shaped section 241 and a straight section 242. The arc-shaped section 241 is located below the side of the screen assembly mounting cavity 22 near the rice milling fixed housing, and its curvature is the same as that of the screen assembly mounting cavity 22. By fixing one end of the arc-shaped section 241 to the side of the crushing fixed housing 2 near the rice milling fixed housing 1, and by positioning the arc-shaped section 241 below the screen assembly mounting cavity 22 along its curvature, the material passes through the crushing rotor... After being crushed by component 211, the material is then screened by screen component 221 and falls onto the arc-shaped section 241 with a certain buffer, allowing the material to slide more smoothly along the discharge channel 24 to the discharge port 23. The arc-shaped section 241 also makes more efficient use of the internal space of the crushing and fixing housing 2 without increasing the volume of the rice milling machine's outer shell. A straight section 242 extending along the tangent of the arc-shaped section 241 is provided between the arc-shaped section 241 and the discharge port 23, allowing the material to flow out quickly along the straight section 242, improving discharge efficiency and ensuring smooth material output without leakage. Furthermore, if... Figure 7As shown, the straight section 242 gradually converges towards the discharge port 23 at one end, so as to guide all the material falling from the screen assembly 221 to be discharged from the discharge port 23; and the end of the discharge channel 24 near the rice milling fixed housing 1 is higher than the end of the discharge channel 24 near the discharge port 23; the discharge channel 24, which is inclined along the length of the crushing fixed housing 2, is conducive to the material crushed by the crushing rotor being quickly and smoothly transported to the discharge port 23 under the action of gravity, so that the material is not easy to accumulate and form blockage during the downward slide, ensuring the stable operation of the equipment, reducing the direct flow time of the material in the crushing fixed housing 2, and effectively improving the processing efficiency and production capacity of the crushing rotor; the discharge channel 24 is inclinedly set inside the crushing fixed housing 2 and connected to the discharge port 23 opened on one side of the crushing fixed housing 2, so that the material is directly output along the discharge channel 24 set in the crushing fixed housing 2, without the need to install the discharge hopper 25 in the rice milling. Below the crushing shell, there will be no material leakage due to the gap between the discharge channel 24 and the crushing fixed shell 2. The width of the discharge channel 24 is the same as the width of the screen assembly mounting cavity 22, which prevents material from leaking out from the gap between the discharge channel 24 and the screen assembly mounting cavity 22. The discharge channel 24 and the crushing fixed shell 2 are welded together to ensure the stability of the connection and the sealing of the connection, thus preventing material leakage. On the outside of the crushing fixed shell 2, there is a discharge hopper 25 that communicates with the discharge port 23. The discharge hopper 25 is inclined along the inclined direction of the discharge channel 24 on the outside of the crushing fixed shell 2, so that the material is guided by the discharge channel 24 and output from the discharge port 23, and then guided and transported to the collection container by the inclined discharge hopper 25. The discharge hopper 25 is inclined along the inclined direction of the discharge channel 24 so that the material can fall directly into the collection container and prevent the material from scattering directly from the discharge port 23. Furthermore, by placing the discharge channel 24 inside the crushing and fixing housing 2, not only can the leakage of material be effectively reduced, but the volume of the entire rice milling and crushing machine housing can also be reduced, making it easier to package and transport. Moreover, since both the discharge channel 24 and the discharge hopper 25 are located on the outer shell of the rice milling and crushing machine, when it is installed on the frame 5, there is no need to consider whether the discharge hopper 25 and the discharge channel 24 will affect the normal installation of the rice milling and crushing machine housing, saving the space occupied by the rice milling and crushing outer shell and providing more flexibility for the arrangement of other components such as motors and transmission devices installed in the frame 5, which is beneficial for the subsequent assembly of the rice milling and crushing combination machine.

[0023] To facilitate packaging and transportation of the rice milling machine casing, the discharge hopper 25 is detachably connected to the crushing fixed housing 2. Specifically, the end of the discharge hopper 25 connected to the crushing fixed housing 2 is provided with a mounting base, which is connected to the crushing fixed housing 2 by bolts. This detachable connection allows the rice milling machine casing to be cubic in shape when the discharge hopper 25 and other components are not installed, facilitating packaging and transportation. Furthermore, the appropriate size of the discharge hopper 25 can be selected for installation according to the actual material discharge situation to adapt to different working environments and material discharge requirements. Moreover, the discharge direction and distance of the material can be changed by altering the tilt angle and position of the discharge hopper 25.

[0024] The existing movable housing 3 is usually fixed to the rice milling fixed housing 1 by a pin structure, thereby ensuring that the bran inlet 33 of the movable housing 3 is aligned with the bran outlet 14 of the rice milling fixed housing 1, and ensuring the connection stability of the movable housing 3, rice milling fixed housing 1, and crushing fixed housing 2 during use. However, after long-term use, the pin structure may deform, leading to unstable connection and causing the bran inlet 33 of the movable housing 3 to misalign with the bran outlet 14 of the rice milling fixed housing 1, resulting in bran leakage. To ensure the connection stability of the movable housing 3 with the mutually fixed rice milling fixed housing 1 and crushing fixed housing 2, and to ensure that the bran inlet 33 of the movable housing 3 is always aligned with the bran outlet 14 of the rice milling fixed housing 1 during long-term use, the movable housing 3 is provided with a locking bolt 31 for connecting with the crushing fixed housing 2. The locking bolt 31 passes through the movable housing 3 and is threadedly connected to the crushing fixed housing 2. A through-hole is formed on the movable housing 3. A through hole 32 is provided in the movable housing 3. A threaded hole 26 corresponding to the through hole 32 is provided on the crushing and fixing housing 2. One end of the locking bolt 31 passes through the through hole 32 and is threadedly connected to the threaded hole 26. The locking bolt 31 is used to connect the movable housing 3 and the crushing and fixing housing 2 to ensure the connection strength between the movable housing 3 and the crushing and fixing housing 2. During use, the locking bolt 31 is not easily deformed, ensuring the connection stability between the movable housing 3 and the crushing and fixing housing 2. This ensures that the bran inlet 33 of the movable housing 3 and the bran outlet 14 of the rice milling fixing housing 1 are always aligned, preventing material leakage. As a preferred method, to facilitate the locking bolt 31 passing through the through hole 32, the locking bolt 31 includes a straight rod section and a threaded end connected in sequence. The straight rod section passes through the through hole 32, and the threaded section is threadedly connected to the threaded hole 26, so as to achieve the purpose of quickly connecting the locking bolt to the threaded hole 26 provided on the crushing and fixing housing 2, which is convenient for operators to install and disassemble.

[0025] To reduce the noise level of the rice milling machine's outer casing during use and minimize the impact of vibration on the casing itself, the crushing fixed housing 2 and the rice milling fixed housing 1 are integrally formed. When the movable housing 3 is connected to the crushing fixed housing 2 and the rice milling fixed housing 1, the top surface of the movable housing 3 is flush with the top surfaces of the crushing fixed housing 2 and the rice milling fixed housing 1. This flush design effectively reduces the noise caused by vibration between the movable housing 3 and the rice milling fixed housing 1. The gap created by the height difference between the two ensures a tight fit of all contact surfaces between the movable housing 3, the rice milling fixed housing 1, and the crushing fixed housing 2. This effectively reduces noise caused by vibration during equipment operation and minimizes the impact of vibration on the rice milling and crushing machine's outer shell. It also helps enhance the sealing between the three components, ensuring that dust does not leak from the gaps. Furthermore, the flush top design allows the movable housing 3, the rice milling fixed housing 1, and the crushing fixed housing 2 to form a regular cuboid when they are joined, which helps enhance the structural stability of the rice milling and crushing machine's outer shell and facilitates packaging and transportation.

[0026] This utility model also provides a rice milling and pulverizing combination machine using the above-mentioned rice milling and pulverizing machine shell, including a frame 5. The rice milling fixed shell 1 and the pulverizing fixed shell 2 are detachably installed on the top of the frame 5. The rice milling component mounting cavity 11 is provided with a rice milling component 111, the pulverizing screen mounting cavity is provided with a pulverizing screen component 221, and the pulverizing rotor mounting cavity 21 is provided with a pulverizing rotor component 211.

The top of the movable shell 3 is provided with a first pulverizing machine inlet 34, and the end face of the movable shell 3 is provided with a second pulverizing machine inlet 35. The outlet 23 is located above the frame 5, and the bottom of the discharge hopper 25 is higher than the frame 5. A motor 51 is provided below the frame 5, and the rice milling component 111 and the pulverizing rotor component 211 are connected to the motor 51 for transmission. Figures 2-6As shown, the rice milling and pulverizing combination machine includes a frame 5 and a rice milling and pulverizing machine shell. The rice milling and pulverizing machine shell is detachably installed on the top of the frame 5. Specifically, the rice milling fixed shell 1 and the pulverizing fixed shell 2 are detachably installed on the top of the frame 5. The movable shell 3 is movably installed on the pulverizing fixed shell 2 via a hinge 4. The rice milling component mounting cavity 11 houses the rice milling component 111, the screen assembly mounting cavity 22 houses the screen assembly 221, and the pulverizing rotor mounting cavity 21 houses the pulverizing rotor assembly 211. The top of the rice milling fixed shell 1 has a rice milling machine inlet 12, which is connected to the base 122. The rice milling machine has a feeding hopper 121. The end face of the rice milling fixed housing 1 has a rice outlet 13, which is equipped with a rice outlet adjustment mechanism 131. The top of the movable housing 3 has a first pulverizer inlet 34, which can be connected to a first pulverizer hopper via a base 122. The end face of the movable housing 3 has a second pulverizer inlet 35, which is detachably connected to a second pulverizer hopper 351 via a mounting base. The side of the movable housing 3 has a bran inlet 33, and the side of the rice milling fixed housing 1 has a bran outlet 14. When the movable housing is simultaneously connected to the rice milling fixed housing... When the main body 1 and the crushing fixed housing 2 are connected, the bran inlet 33 and the bran outlet 14 are aligned; the movable housing 3 is provided with an inclined conveying hopper connected to the crushing fixed housing 2, so as to input the material into the crushing fixed housing 2 for crushing; the discharge port 23 is located on the side of the crushing fixed housing 2 away from the rice milling fixed housing 1, the bottom of the discharge hopper 25 is higher than the frame 5, and the motor 51 is provided below the frame 5. The rice milling assembly 111 and the crushing rotor assembly 211 are connected to the motor 51 through the belt drive assembly 52; by setting the discharge channel 24 inside the crushing fixed housing 2 and connecting it with the material opened in the crushing fixed housing 1, the material is crushed. The discharge port 23 on one side is connected, eliminating the need to install the discharge channel 24 and discharge hopper 25 below the rice milling shell, thus avoiding the occupation of internal space in the frame 5. This provides more flexibility for the arrangement of other components such as the motor 51 and transmission device, which is beneficial for the subsequent assembly of the rice milling combination machine. Furthermore, setting the discharge channel 24 inside the crushing fixed shell 2 effectively saves the space occupied by the rice milling shell, making the rice milling shell a regular cube, which is beneficial for later packaging and transportation. Moreover, the integrated setting of the discharge channel 24 and the crushing fixed shell 2 can effectively avoid material leakage caused by gaps.
