Description

Technical Field

[0001] The utility model relates to the field of rice hulling machines, and particularly relates to a hulling machine for rice production. Background Art

[0002] The hulling machine, as a powerful assistant in agricultural production, is mainly used for the hulling and screening of granular crops. Its working principle is to make the granular crops contact with the hulling elements through mechanical friction, so as to remove the outer hull of the crops and achieve the dual purposes of screening and hulling.

[0003] However, in actual operation, we need to note that the stacking height of rice at the roller docking part has a significant impact on the performance of the hulling machine. When the rice stacks too high here, the contact area between the paddy and the roller will be correspondingly reduced, thus weakening the extrusion and rubbing effects that the paddy receives between the rollers and resulting in a reduction in hulling efficiency. On the contrary, if the stacking is too low, although the contact area increases, the quantity of paddy decreases, which will also affect the hulling effect.

[0004] More critically, the uneven stacking of rice will also cause the paddy to receive uneven forces during the hulling process. Especially in the area where the stacking is too high, the pressure on the paddy is greater and it is more likely to be broken, thus increasing the breakage rate of brown rice. In addition, the uneven stacking will increase the rotational resistance of the roller, resulting in an increase in the energy consumption of the hulling machine. To maintain the hulling efficiency, it may be necessary to increase the rotational speed or pressure of the roller, but this will undoubtedly further exacerbate the energy consumption problem.

[0005] Finally, the uneven stacking of rice will also cause uneven wear on the roller. Especially in the area where the stacking is too high, the wear of the roller will be more serious, which will not only shorten the service life of the equipment, but also may increase the additional maintenance cost. Therefore, when using the hulling machine, it is crucial to ensure the uniform stacking of rice at the roller docking part. Summary of the Utility Model

The lower end of the sawtooth strip is provided with a leveling brush, and the leveling brush extends to the rollers with a height difference to reduce the rice accumulation height at the two rollers.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the present invention, the design of the flattening structure plays a vital role in improving the efficiency of rice processing. This structure, which includes serrated strips and flattening brushes, is carefully laid out, and its significant effect is reflected in the effective reduction of the accumulation height of rice at the roller. Such design optimization ensures the smooth flow of rice during the rice processing process without the need to stay in a certain position, thereby greatly improving the efficiency of the entire rice processing process.

Whether it is daily maintenance or troubleshooting, it can be efficiently completed in a short time, ensuring the continuous and stable operation of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Embodiment 1

[0027] In Figures 1 to 4In the detailed display of , we introduced a rice milling machine specifically for rice production. The equipment is mainly composed of a chassis 1, a feed port 2, a transmission device 4, a discharge port 7, two servo motors and rollers with a height difference. Among them, the feed port 2 and the discharge port 7 are respectively arranged at the upper and lower ends of the chassis 1, and a support frame 8 is installed at the bottom of the chassis 1 to ensure the stability of the equipment. The first servo motor 5 is installed on the support frame 8 and is tightly connected to a roller inside the chassis 1 through the transmission device 4. The second servo motor 6 is directly installed on the side wall of the chassis 1 and is connected to another roller. The two work together to realize the rice milling process through the height difference between the rollers.

[0028] In order to filter the rice after glutinous rice, filter holes 9 are specially provided at the bottom of the housing 1. These filter holes 9 are located just below the discharge port 7 to ensure that the rice is effectively filtered when it flows out.

[0029] In addition, we also opened a mounting groove 10 on the side wall of the chassis 1. An arc-shaped mounting block 15 is installed in this groove, and a bending strip 11 is provided on the inner wall of the mounting block. A sawtooth strip 12 extends from the lower end of the bending strip 11, and a sawtooth notch 13 is formed at the lower end. This design helps to better handle the rice. At the bottom of the sawtooth strip 12, we added a flat brush 14, which extends to the vicinity of the roller, effectively reducing the accumulation height of rice at the two rollers.

[0030] It is worth mentioning that the serrated bar 12 is composed of a plurality of arc-shaped bars of different lengths, which are firmly fixed to the bending bar 11 by welding. The cross-sectional design of the serrated bar 12 is a unique "丿" shape. The bending bar 11 is made of aluminum alloy bending material to ensure its strength and durability. At the same time, the bending bar 11 is also connected to the arc-shaped mounting block 15 by welding to ensure the stability of the overall structure. The arc-shaped mounting block 15 is fixed to the mounting slot 10 of the chassis 1 by a locking assembly, and a sealing strip is also provided at the connection between the mounting block and the chassis 1 to ensure the sealing of the equipment.

[0031] The flat brush 14 is made of rubber material and is fixed to the bottom of the sawtooth bar 12 by hot melting. By adjusting the curvature of the bending strip 11, we can flexibly adjust the distance between the flat brush 14 and the connection between the two rollers to meet different rice processing requirements.

[0032] Embodiment 2

[0033] On the basis of the first embodiment, we added the design of the inspection door 3 to the Gonggu machine. The inspection door 3 is installed at the opening of the side wall at the other end of the chassis 1, just facing the two rollers with a height difference. In this way, when the roller needs to be inspected or maintained, the staff can easily open the inspection door 3 and directly contact the roller part, which improves the convenience and efficiency of maintenance. The inspection door 3 is installed on the chassis 1 through the hinge assembly and the lock assembly to ensure its stability and safety.

[0034] Working process: The working process of the rice-grinding machine mainly revolves around two servo motors (the first servo motor 5 and the second servo motor 6) and rollers with height differences. When the rice enters the chassis 1 from the feed port 2, the two servo motors start working and drive the two rollers to rotate at different speeds. Due to the height difference between the rollers, the rice is subjected to different pressures and frictions when passing through the rollers, thereby achieving the rice-grinding effect. The rice after rice-grinding is filtered through the filter hole 9 at the bottom of the chassis 1 and flows out from the discharge port 7.

[0035] When the rice is piled up too high at the roller, the sawtooth bar 12 and the leveling brush 14 come into play. The sawtooth bar 12 effectively disperses and guides the rice flow through its unique "丿" shaped cross-section design and the sawtooth-shaped notch 13. At the same time, the leveling brush 14 can contact and sort the rice at the roller through the softness of its rubber material and the extensibility of its bristles to reduce the pile height.

[0036] In order to meet different rice processing requirements, the distance between the leveling brush 14 and the connection between the two rollers can be changed by adjusting the curvature of the bending strip 11. This adjustment process can be completed by loosening the lock assembly, adjusting the position of the arc-shaped mounting block 15 in the mounting groove 10, and then re-fixing the lock assembly. After the adjustment is completed, the distance between the leveling brush 14 and the roller will change, thereby realizing flexible adjustment of the rice stacking height.
