Description

Technical Field

[0001] This utility model relates to the field of rice hulling machine technology, and in particular to a rice hulling machine with easily replaceable rubber rollers. Background Technology

[0002] A rice huller is a grain processing machine that removes the husk from paddy rice, turning it into brown rice. It is a key piece of equipment in the paddy processing process, located at the beginning of the process. There are many types of rice hullers, one of which is the rubber roller rice huller. The paddy rice enters through a feeding device and is subjected to compression, tearing, and friction between opposing rotating rubber rollers with different linear speeds. The rapidly rotating rollers generate significant friction on the paddy rice, causing it to rotate with them, while the slower rollers hinder its rotation. Under the combined effect of these two forces, the husk of the paddy rice breaks apart and separates from the brown rice.

[0003] Rubber rollers are heavy, requiring considerable physical effort to handle and install. Furthermore, during installation, the center lines of the two rollers must be parallel and their end faces must be aligned; otherwise, the utilization rate of the rubber rollers will decrease, rubber consumption will increase, and the shelling rate and output will also decrease. Traditional replacement methods cannot guarantee installation accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a rice huller that facilitates the replacement of rubber rollers, thereby solving the aforementioned problems.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rice huller that facilitates the replacement of rubber rollers, comprising a rice huller housing, a hopper, and a drive housing. The hopper is provided on the top of the rice huller housing, and the drive housing is provided on the left side of the rice huller housing. A rubber roller support plate is rotatably mounted on the left side wall inside the rice huller housing. A drive assembly is provided inside the drive housing to drive the rubber roller support plate to rotate. A side plate is provided on the right side of the rice huller housing, and a rubber roller body is rotatably mounted on the side wall of the side plate, with the rubber roller body corresponding to the rubber roller support plate.

[0006] Preferably, a connecting block is fixed to the side wall of the rubber roller support plate, and a connecting groove is provided inside the rubber roller body, so that the connecting block can be inserted into the connecting groove to connect the rubber roller body and the rubber roller support plate.

[0007] Preferably, the upper and lower ends of the side panel sidewall are fixed with insert blocks, and the upper and lower ends of the right side of the rice huller chassis are provided with slots. The slots and insert blocks are positioned opposite each other, and the insert blocks can be inserted into the slots. Fixing blocks are fixed on both sides of the side panel, and bolts are provided in the fixing blocks. One end of the bolt is screwed into a screw hole, which is located on the right side wall of the rice huller chassis.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] This utility model provides a rice huller with an easy-to-replace rubber roller design. Through an innovative design that integrates multiple rubber roller bodies onto a side plate, the disassembly and assembly of the rubber rollers is greatly improved. During disassembly, operators can simply remove the rubber roller bodies directly from the side plate, removing multiple rollers at once, eliminating the tedious process of disassembling each roller individually. During installation, thanks to this design, operators can accurately install multiple rubber roller bodies into the designated positions on the equipment at once, completing simultaneous replacement. This centralized replacement method avoids the lengthy and inefficient process of disassembling and assembling each roller individually, significantly reducing time costs, minimizing downtime, and substantially improving work efficiency.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0017] Combination Figures 1 to 4As shown, this utility model discloses a rice huller with easy-to-replace rubber rollers, including a rice huller housing 1, a hopper 2, and a drive housing 3. The hopper 2 is provided on the top of the rice huller housing 1, and the drive housing 3 is provided on the left side of the rice huller housing 1. A rubber roller support plate 31 is rotatably provided on the left side wall inside the rice huller housing 1. A drive assembly 32 is provided inside the drive housing 3 to drive the rubber roller support plate 31 to rotate. A side plate 4 is provided on the right side of the rice huller housing 1, and a rubber roller body 43 is rotatably provided on the side wall of the side plate 4. The rubber roller body 43 corresponds to the rubber roller support plate 31.

[0018] A connecting block 44 is fixed to the side wall of the rubber roller support plate 31, and a connecting groove 48 is provided inside the rubber roller body 43. The connecting block 44 can be inserted into the connecting groove 48 to connect the rubber roller body 43 and the rubber roller support plate 31.

[0019] Insert blocks 41 are fixed at the upper and lower ends of the side wall of the side plate 4. Slots 42 are provided at the upper and lower ends of the right side of the rice huller chassis 1. The slots 42 and the insert blocks 41 are directly opposite each other, and the insert blocks 41 can be inserted into the slots 42. Fixing blocks 45 are fixed on both sides of the side plate 4. Bolts 46 are provided in the fixing blocks 45. One end of the bolts 46 is screwed into the screw holes 47. The screw holes 47 are opened on the right side wall of the rice huller chassis 1.

[0020] Working principle:

[0021] First, align the inserts 41 at the upper and lower ends of the side wall of the side plate 4 with the slots 42 pre-drilled on the right side wall of the rice huller housing 1. Then, slowly push the side plate 4 so that the rubber roller body 43, which is placed on the side wall of the side plate 4, can be smoothly pushed into the rice huller housing 1. During this process, the installation position of the side plate 4 is precisely defined by the engagement of the inserts 41 and the slots 42, thereby ensuring that the connecting groove 48 inside the rubber roller body 43 can be accurately positioned relative to the connecting block 44.

[0022] A steady thrust is continuously applied to push the side plate 4 until the connecting block 44 is fully inserted into the connecting groove 48. When the side plate 4 is tightly and seamlessly attached to the side wall of the rice huller housing 1, a stable connection between the rubber roller support plate 31 and the rubber roller body 43 is successfully achieved.

[0023] Finally, the bolt 46 is smoothly inserted into the fixing block 45 and precisely screwed into the screw hole 47. The fixing block 45 is tightened by applying appropriate pressure with the bolt 46, thus completing the fixing and installation of the side plate 4. At this point, the installation process of the rubber roller body 43 is successfully completed.

[0024] When it is necessary to disassemble the rubber roller body 43, the operation process is relatively simple. Just slowly unscrew the bolt 46 from the screw hole 47, and then gently pull the side plate 4 to make the connecting groove 48 inside the rubber roller body 43 separate smoothly from the connecting block 44, and the rubber roller body 43 can be easily removed;

[0025] By repeating the above steps, the replacement of the rubber roller body 43 can be achieved efficiently. The advantage of this replacement method is that it allows for the replacement of multiple rubber roller bodies 43 at once, avoiding the tedious process of disassembling and assembling each individual rubber roller body 43, thus greatly saving valuable time and significantly improving work efficiency and the convenience of equipment maintenance.
