Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically to a rice hulling device. Background Technology

[0002] After rice is harvested, it needs to be hulled to become rice. Current technology generally uses a rubber roller huller to remove the husks. Its working principle involves setting up two rubber rollers with different rotational speeds. The rice is evenly spread into the gap between the two rollers, and the speed difference causes the husks to be broken apart. During the hulling process, the rubber rollers wear down due to prolonged friction with the rice. When the wear exceeds a certain limit, the rollers need to be replaced. Because the pierced roller is fixedly connected to the inner ring, it must be replaced along with the inner ring, which increases maintenance costs.

[0003] In order to solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a rice hulling device in which the outer rubber roller can be replaced separately, thereby reducing maintenance costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a rice hulling device, comprising a feeding hopper and a hulling chamber, wherein two hulling rollers with different rotation speeds are arranged in the hulling chamber, the feeding hopper feeds material toward the gap between the two hulling rollers, each hulling roller comprises a drum, an independent rubber ring fitted on the outside of the drum, a first end plate fixedly installed at one end of the drum, and a second end plate detachably installed at the other end of the drum, the edges of the first end plate and the edges of the second end plate clamping the two ends of the independent rubber ring; at least one axial insertion hole is opened through the independent rubber ring, and an axial insertion rod that cooperates with the axial insertion hole is fixed on the first end plate so that the independent rubber ring rotates synchronously with the drum.

[0006] Based on the above, the roller includes an outer cylinder and a central rotating shaft located at the central axis of the outer cylinder. The outer cylinder has a port at one end facing the second end plate, and the central rotating shaft has a threaded section at one end facing the second end plate. The threaded section does not extend beyond the port. The second end plate has a recessed portion at its center that extends into the port. The recessed portion has a through hole corresponding to the threaded section. The threaded section passes through the through hole and is locked by a lock nut.

[0007] Based on the above, the shelling chamber includes a chamber body and a side door. An inspection port is provided on the side of the chamber body. The second end plate is located near the inspection port. The four corners of the side door are bolted to the inspection port.

[0008] Based on the above, an observation window is also provided on the side door.

[0009] Based on the above, a total of six axial insertion rods are provided, and the six axial insertion rods are evenly arranged around the roller.

[0010] This utility model has substantial features and progress compared to the prior art. Specifically, by disassembling and assembling the second end plate, the end of the roller can be blocked or opened, making it convenient to put the independent rubber ring into or peel it off the roller. When the independent rubber ring is put on the roller, the axial insertion rod is inserted into the axial insertion hole, and the two are locked together and can rotate synchronously. In this way, when the wear reaches a certain degree, the independent rubber ring can be replaced separately, thereby reducing maintenance costs.

[0011] Furthermore, by opening the port on the outer cylinder and setting the recessed portion at the center of the second end plate, the recessed portion extends into the interior of the outer cylinder for installation, which can avoid leaving a large gap between the end of the outer cylinder and the side door, thereby preventing rice leakage; by setting the threaded section on the central rotating shaft, the second end plate can be locked with a single locking nut, simplifying the disassembly and assembly steps.

[0012] Furthermore, the side door allows the entire side of the compartment to be opened for easy inspection and maintenance; the observation window facilitates the observation of the wear level of the independent rubber ring. Attached Figure Description

[0017] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0018] like Figure 1-3As shown, a rice hulling device includes a feeding hopper 1 and a hulling chamber. The hulling chamber is equipped with two hulling rollers 3 with different rotation speeds. The feeding hopper 1 feeds rice grains into the gap between the two hulling rollers 3. The two hulling rollers 3 rotate at different speeds, thereby breaking open the rice husks. This is a common device in the field and does not require any creative effort.

[0019] To reduce maintenance costs, each peeling roller 3 includes a roller, an independent rubber ring 31 fitted on the outside of the roller, a first end plate 32 fixedly installed at one end of the roller, and a second end plate 33 detachably installed at the other end of the roller. The edges of the first end plate 32 and the second end plate 33 clamp the two ends of the independent rubber ring 31. By removing and installing the second end plate 33, the end of the roller can be blocked or opened, making it convenient to put the independent rubber ring 31 into or peel it off the roller for individual replacement. The independent rubber ring 31 has six axial insertion holes. The first end plate 32 is fixed with axial insertion rods 34 that cooperate with the axial insertion holes. The six axial insertion rods 34 are evenly distributed around the roller so that the independent rubber ring 31 is locked to the roller as one unit and can rotate synchronously.

[0020] The shelling chamber specifically includes a chamber body 2 and a side door 4. The side of the chamber body 2 has an inspection port, and the second end plate 33 is located near the inspection port. The four corners of the side door 4 are bolted to the inspection port. The side door 4 can open the entire side of the shelling chamber for easy inspection and maintenance. The side door 4 is also provided with an observation window 5, which allows observation of the wear condition of the independent rubber ring 31 from the outside.

[0021] The roller specifically includes an outer cylinder 35 and a central rotating shaft 36 located at the central axis of the outer cylinder 35. The outer cylinder 35 has a port at one end facing the second end plate 33, and the central rotating shaft 36 has a threaded section 37 at one end facing the second end plate 33. The threaded section 37 does not extend beyond the port, thus avoiding a large gap between the end of the outer cylinder 35 and the side door 22, thereby preventing rice leakage. The second end plate 33 has a recessed portion 38 at its center that extends into the port. The recessed portion 38 has a through hole corresponding to the threaded section 37. After the threaded section 37 passes through the through hole, it is locked by a locking nut 39. This allows the second end plate 33 to be locked with a single locking nut 39, simplifying the assembly and disassembly process.

[0022] Working principle:

[0023] When the wear of the independent rubber ring 31 exceeds the allowable level, the side door 4 is opened, the locking nut 39 is unscrewed, the second end plate 33 is removed, the independent rubber ring 31 is pulled out, and a new independent rubber ring 31 is fitted onto the roller. The axial insertion rod 34 is inserted into the axial insertion hole. Finally, the second end plate 33, the locking nut 39 and the side door 4 are put back in their original positions to complete the maintenance. This method eliminates the need to replace the entire peeling roller 3 in traditional maintenance, thereby reducing maintenance costs.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
