Description

Technical Field

[0001] This utility model relates to the field of rice hulling machine technology, and more specifically to a rice hulling machine rubber roller that is resistant to high-temperature damage. Background Technology

[0002] A rice huller is a grain processing machine that removes the husk from paddy rice to produce brown rice. It removes the outer husk of paddy rice, reduces grain breakage and surface damage, and preserves the brown rice as intact as possible. The hulling rollers are the main components of the rice huller and are the key equipment for removing paddy rice. Their working principle is that two rollers rotate in opposite directions at different speeds, causing the paddy rice to enter between the two rollers, where it is squeezed, torn, and peeled, thereby achieving the purpose of removing the husk from the rice.

[0003] Existing technology has shortcomings: on the one hand, the pressure between the rubber rollers will convert mechanical energy into heat energy; on the other hand, the internal space of the rice huller is small and lacks heat dissipation channels, which makes it difficult for heat to dissipate quickly, causing the temperature of the rubber rollers to rise and the performance to decrease (rubber aging, hardening or even cracking), affecting the service life.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The rice huller rubber roller that is protected against high temperature damage involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Reference Figures 1 to 4 This utility model provides a rice huller rubber roller that is protected against high temperature damage, including a housing 1. The top of the housing 1 is provided with a feed inlet 2. One side of the bottom of the housing 1 is provided with a receiving groove 3 and the other side is provided with a shell receiving groove 4. The inside of the housing 1 is provided with a shell removal mechanism 5, which is located below the feed inlet 2. One end of the shell removal mechanism 5 extends to the outside of the housing 1 and is fixedly connected to a wind-cooling mechanism 6. A blower 7 is provided on the side of the housing 1 above the receiving groove 3.

[0027] A first fixed rod 501 is fixedly connected to the inner wall of the housing 1. A movable roller 502 is movably connected to one side of the top end of the first fixed rod 501, and a fixed roller 503 is fixedly connected to the other side. A second fixed rod 504 is movably connected to the end of the movable roller 502 away from the first fixed rod 501. The end of the fixed roller 503 away from the first fixed rod 501 is fixedly connected to the top end of the second fixed rod 504. The movable roller 502 and the fixed roller 503 extend out of the wall shell of the housing 1 at the end near the second fixed rod 504 and are fixedly connected to the cover 601 of the air-cooling mechanism 6. A honeycomb-shaped ventilation hole 101 is opened on the wall shell of the housing 1 on the side of the first fixed rod 501 at the same horizontal position as the movable roller 502 and the fixed roller 503. A through hole for the movable roller 502 and the fixed roller 503 to pass through is opened on the wall shell of the housing 1 on the side of the second fixed rod 504.

[0028] The feed inlet 2 is located on the center line of the gap between the moving roller 502 and the fixed roller 503. A guide plate 8 is provided below the moving roller 502 and the fixed roller 503. The guide plate 8 includes a downwardly inclined plate 1 801 and an inclined plate 2 802. The top ends of the inclined plate 1 801 and the inclined plate 2 802 are fixedly connected to the inner wall of the machine casing 1. A secondary shelling roller 505 is provided below the gap between the two bottom ends. The secondary shelling roller 505 has the same structure as the upper moving roller 502 and the fixed roller 503 used for preliminary shelling. An air outlet 701 is provided on the lower right side of the secondary shelling roller 505. A receiving groove 3 is provided below the air outlet 701. A shell receiving groove 4 is provided on the opposite side of the receiving groove 3. One end of the air outlet 701 is located outside the wall of the machine casing 1 and is fixedly connected to a fan 702.

[0029] Reference Figures 5 to 8 The moving roller 502 includes an outer rubber layer 5021 that is in direct contact with the rice and an inner ring plate 5022 that provides support. The rubber layer 5021 is made of high wear-resistant rubber. The inner wall of the ring plate 5022 is provided with an annular array of long grooves to increase the heat dissipation area inside the roller and improve heat dissipation efficiency. A connecting block 5023 is fixedly connected to the protrusion. A short rod 5024 is fixedly connected to the bottom end of the connecting block 5023. A shaft 5025 is fixedly connected to the bottom end of the short rod 5024. The short rods 5024 are evenly distributed in three longitudinal rows on the side of the shaft 5025. A motor 5026 is fixedly connected to one end of the shaft 5025.

[0030] When motor 5026 starts, it drives shaft 5025 to rotate. Shaft 5025 controls the rotation of ring plate 5022 and rubber layer 5021 through short rod 5024 on its side and connecting block 5023. Each rubber roller is controlled by a corresponding motor to rotate in opposite directions at different speeds, thus dehulling the passing rice.

[0031] In this design, one end of the shaft 5025 is fixedly connected to the motor 5026, and a first small bearing 5011 is fixedly connected to the bottom end of the first small bearing 5011. The bottom end of the slider 5012 is movably connected to the inside of the sliding groove rod 5013. A lead screw 5014 is movably connected inside the sliding groove rod 5013, with its side movably connected to the bottom end of the slider 5012. One end of the lead screw 5014 extends out of the sliding groove. A handwheel 5015 is fixedly connected to the end of rod 5013 and the wall of housing 1. Rotating the handwheel 5015 will cause the lead screw 5014 to rotate, thereby controlling the slider 5012 to move in the groove, and thus controlling the distance between the moving roller 502 and the fixed roller 503. A fixed seat 5016 is fixedly connected to the top of the sliding rod 5013. The top of the fixed seat 5016 is movably connected to the shaft 5031 of the fixed roller 503 through the second small bearing 5017.

[0032] When the motor 5026 controls the shaft 5025 to rotate, it is fixedly connected to the inner wall of the housing 1 through the bearing at its end and the sliding rod 5013. The fixed roller 503 is fixed on the sliding rod 5013 and cannot be moved. The moving roller 502 can be adjusted in position by rotating the handwheel 5015. When the temperature rises, the distance between the two rollers is adjusted to reduce the pressure and thus reduce the heat generated by friction.

[0033] Among them, the ring plate 5022 is aligned with the edge of the outer rubber layer 5021 on one side of the first fixed rod 501, and extends out of the edge of the rubber layer 5021 on the side of the motor 5026, and is embedded in the through hole opened in the housing 1. The ring plate 5022 is fixedly connected to the first large bearing 5041 at the gap between itself and the wall of the housing 1 where it is not covered by the rubber layer 5021. The bottom end of the first large bearing 5041 is movably connected to the top end of the second sliding rod 5042. The top end of the other side of the second sliding rod 5042 is fixedly connected to the second large bearing 5043. The interior of the second large bearing 5043 is fixedly connected to one end of the second shaft 5031. The interior of the second sliding rod 5042 is provided with a second lead screw 5044. One end of the second lead screw 5044 extends out of the end of the second sliding rod 5042 and is fixedly connected to the wall of the housing 1 with a second handwheel 5045.

[0034] Reference Figures 2 to 3 A cover 601 is fixedly connected to the side of the motor 5026. The edge of the cover 601 is fixedly connected to the side of the machine housing 1. An exhaust fan 602 is provided in the middle of the cover 601. When the exhaust fan 602 is activated, the gas inside the cover 601 can be exchanged with the outside, carrying away heat. At the same time, the inner wall of the inner ring plate 5022 of the rubber roller has an annular array of long grooves that communicate with the cover 601. The other end is near the inner wall of the machine housing 1 with honeycomb-shaped ventilation holes 101, forming a cooling channel to quickly dissipate the heat generated by the rubber roller during operation and the heat accumulated inside the rice huller, thus completing the heat dissipation.

[0035] The working principle of this utility model is as follows: Rice is fed into the device through the feed inlet 2. After being dehulled by the dehulling mechanism 5, it is screened by the blower 7. The rice husks fall into the receiving trough 4, and the rice enters the receiving trough 3. During this process, the air-cooling mechanism 6 dissipates heat and cools the dehulling mechanism 5.

[0036] After the rice grains enter the casing 1, they fall between the moving roller 502 and the fixed roller 503. The moving roller 502 and the fixed roller 503 rotate at opposite speeds, causing the rice grains to be squeezed and torn between the two rollers, thereby completing the separation of rice husks and rice. During this process, one end of the moving roller 502 and the fixed roller 503 is connected to the air-cooling mechanism 6, and the other end is connected to the outside through the honeycomb-shaped ventilation holes 101, forming an internal cooling channel for the moving roller 502 and the fixed roller 503, completing heat dissipation and effectively preventing high-temperature damage.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
