Description

Technical Field

[0001] The utility model relates to the technical field of grain processing equipment, and in particular, to a rice husking rubber roller adjustment device. In addition, the utility model also relates to a rice husking machine comprising the rice husking rubber roller adjustment device. In addition, the utility model also relates to a rice husking and milling combined equipment comprising the rice husking machine. Background Art

[0002] A rice husker is a grain processing machine that removes the husk of rice and makes it into brown rice. It can remove the outer shell of rice, reduce the risk of rice grains bursting and skin damage, and keep the brown rice intact as much as possible. Therefore, it has been widely used in the field of grain processing.

[0003] The rice husker mainly uses rubber rollers with different speeds to squeeze and tear the rice, so that the rice shell is broken and husked. The wear of the rubber rollers and the distance between the rubber rollers will directly affect the rice processing quality and the life of the rubber rollers. If the distance between the rubber rollers is too small, the rubber rollers are easy to wear and the rice is easy to break, resulting in increased rubber consumption and rough crushing rate; if the distance is too large, the rice husking is incomplete and the husking rate is reduced. Therefore, the rubber roller adjustment device is the core component of the rice husker.

[0004] The existing rubber roller adjustment methods mainly include the following: 1. The movable rubber roller is driven by a cylinder to move relative to the fixed rubber roller. Since the cylinder is driven by air pressure, it can apply a flexible rice husking pressure to the rice. Since many equipment in the factory share an air pressure source, the air source pressure is unstable, and the rice husking pressure generated by the cylinder is unstable, which makes the adjustment accuracy of the displacement of the cylinder movement low. As a result, when the rice husker is working, the movable rubber roller is prone to direct contact with the fixed rubber roller and wear each other. Therefore, it is necessary to set a material sensor at the feed port of the rice husker. When the material sensor senses the passage of rice, the cylinder delays driving the movable rubber roller close to the fixed rubber roller to close the rollers. At this time, the movable rubber roller and the fixed rubber roller are separated by rice, and when the material sensor does not sense the passage of rice, the cylinder delays driving the movable rubber roller away The fixed rubber roller is used as a split roller to prevent the movable rubber roller from directly contacting the fixed rubber roller, but the cylinder needs to receive the sensor signal of the material sensor to delay the driving of the movable rubber roller to move. The time of closing the roller and splitting the roller is difficult to grasp, resulting in a low rice husking rate of the first and last feeding; 2. For example, Chinese utility model patent CN217140493U discloses a rice husking rubber roller spacing adjustment device, comprising: a fixed roller, which is fixedly arranged in a rice husking box; a movable roller, which is floatingly arranged in the rice husking box; the central axis of the movable roller is the movable roller shaft, and the movable roller shaft is connected to the telescopic adjustment mechanism; a displacement sensor is arranged on the telescopic adjustment mechanism; when the telescopic adjustment mechanism performs a telescopic action, the movable roller moves, and the gap between the movable roller and the fixed roller changes, and the displacement of the telescopic action is measured by the displacement sensor. It can adaptively adjust the distance between the rubber rollers for husking rice, accurately control the distance between the rubber rollers for husking rice, improve the husking rate, and reduce the rough and broken rate. Since the distance between the fixed roller and the movable roller depends on the type of rice, the distance between the rubber rollers when processing the same kind of rice is fixed. When foreign objects in the rice pass through, the rubber rollers are severely worn. In order to ensure husking, the distance between the rubber rollers is often smaller than the particle size of the rice, and the rough and broken rate is relatively high. Utility Model Content

[0036] like Figure 1-Figure 5As shown, the rice husker rubber roller adjustment device of this embodiment includes a fixed rubber roller 110 for being arranged on the rice husker 100, a movable rubber roller 120 arranged opposite to the fixed rubber roller 110 and for being movably arranged on the rice husker 100, and a rubber roller adjustment mechanism connected to the movable rubber roller 120 for driving the movable rubber roller 120 to approach or move away from the fixed rubber roller 110 and applying a flexible pressure close to the fixed rubber roller 110 to the movable rubber roller 120. The rubber roller adjustment mechanism includes a mounting seat 130 for being arranged on the rice husker 100, a telescopic component 140 slidably arranged on the mounting seat 130 and having a telescopic end connected to the movable rubber roller 120, and an elastic component 150 arranged on the mounting seat 130 and connected to the telescopic end of the telescopic component 140 for applying a flexible pressure close to the fixed rubber roller 110 to the telescopic end of the telescopic component 140. Specifically, the rice husking rubber roller adjustment device of the utility model comprises a fixed rubber roller 110, a movable rubber roller 120 and a rubber roller adjustment mechanism arranged on the rice husking machine 100. When the rice husking machine 100 is in operation, the rubber roller adjustment mechanism installs the telescopic component 140 and the elastic component 150 by arranging the mounting seat 130 on the rice husking machine 100, and the telescopic end of the telescopic component 140 is extended and retracted to drive the movable rubber roller 120 to approach or move away from the fixed rubber roller 110, thereby adjusting the gap between the fixed rubber roller 110 and the movable rubber roller 120 to achieve material adjustment. During the rice husking operation, the elastic component 150 applies a flexible pressure close to the fixed rubber roller 110 to the telescopic end of the telescopic component 140, and then applies a flexible pressure close to the fixed rubber roller 110 to the movable rubber roller 120 through the telescopic end of the telescopic component 140, so as to realize the flexible linkage of the movable rubber roller 120, thereby applying a flexible pressure to the material, ensuring the stable shelling effect and the shelling rate, and when the material or foreign matter passes by and applies a reaction force to the movable rubber roller 120, the reaction force can overcome the flexible pressure so that the telescopic component 140 is relatively stable. The mounting seat 130 moves in a direction away from the fixed rubber roller 110, thereby increasing the gap between the fixed rubber roller 110 and the movable rubber roller 120, which facilitates the rapid passage of materials and foreign objects. After the materials or foreign objects pass through, the telescopic assembly 140 quickly resets under the action of the flexible pressure, thereby preventing the rough materials or foreign objects from seriously wearing the fixed rubber roller 110 and the movable rubber roller 120, reducing the rough breakage rate, and extending the service life of the fixed rubber roller 110 and the movable rubber roller 120. 0 and the elastic component 150 cooperate with each other to realize the flexible linkage of the movable rubber roller 120, so that the gap between the fixed rubber roller 110 and the movable rubber roller 120 can be adaptively adjusted according to the object passing through, and quickly restored after the adjustment. Compared with the prior art, while ensuring the hulling rate of rice, the rough crushing rate is reduced, and the wear degree of the fixed rubber roller 110 and the movable rubber roller 120 during the working process is reduced as much as possible, so as to extend the service life of the fixed rubber roller 110 and the movable rubber roller 120. It has strong practicality and is suitable for wide promotion and application.It should be understood that the movable rubber roller 120 can be driven to move to increase the husking gap only when the particle size of the material is large enough to overcome the flexible pressure. Under normal circumstances, the husking gap remains unchanged.

[0037] like Figure 3 As shown, in this embodiment, the telescopic assembly 140 includes a sliding seat 141 slidably arranged on the mounting seat 130, a driving member 142 arranged on the sliding seat 141, a screw sleeve 143 connected to the rotating end of the driving member 142, and a telescopic screw 144 threadedly connected to the screw sleeve 143 and connected to the movable rubber roller 120. Specifically, the driving member 142 is installed through the sliding seat 141, and the driving member 142 works to drive the screw sleeve 143 to rotate, thereby driving the telescopic screw 144 away from or close to the screw sleeve 143, and then driving the movable rubber roller 120 away from or close to the fixed rubber roller 110, so as to adjust the distance between the movable rubber roller 120 and the fixed rubber roller 110, so as to achieve the adjustment of the rice husking gap.

[0038] like Figure 3 As shown, in this embodiment, the elastic component 150 includes a support seat 151 fixedly arranged on the mounting seat 130 and sleeved on the outside of the telescopic screw rod 144, and a compression spring 152 sleeved on the outside of the telescopic screw rod 144 and respectively fixedly connected to the end of the telescopic screw rod 144 away from the screw rod sleeve 143 and the support seat 151. Specifically, in the initial state, the compression spring 152 is in a compressed state, and the support seat 151 is fixed. Therefore, the compression spring 152 applies elastic force to drive the telescopic screw 144 to move toward the direction close to the fixed rubber roller 110, and then drives the screw sleeve 143, the driving member 142 and the sliding seat 141 to move toward the direction close to the fixed rubber roller 110. When the driving member 142 works to move the telescopic screw 144 away from the screw sleeve 143, and then makes the movable rubber roller 120 close to the fixed rubber roller 110, so as to achieve the adjustment of the rice husking gap, the compression spring 152 is still in a compressed state, and can apply flexible pressure to the telescopic screw 144, thereby realizing flexible linkage of the movable rubber roller 120.

[0039] In this embodiment, the rubber roller adjustment mechanism further includes a displacement sensor assembly 160, which includes a connection seat 161 fixedly arranged on the support seat 151, a positioning plate 162 fixedly arranged on the end of the telescopic screw 144 away from the screw sleeve 143, and a displacement sensor 163 telescopically arranged on the connection seat 161 and the telescopic end is fixedly connected to the positioning plate 162. Specifically, when the telescopic screw 144 is extended or retracted, the positioning plate 162 is driven to move synchronously, and then the telescopic end of the displacement sensor 163 is driven to move synchronously, and then the telescopic amount of the telescopic screw 144 is collected in real time through the displacement sensor 163, so as to adjust the gap between the movable rubber roller 120 and the fixed rubber roller 110.

[0040] like Figure 3 As shown, in the present embodiment, a mounting member 131 slidably connected to a sliding seat 141 is arranged on the mounting seat 130, and the mounting member 131 includes a first mounting portion, a second mounting portion and a mounting shaft 132, the first mounting portion and the second mounting portion are arranged at intervals on the mounting portion, and the axial ends of the mounting shaft 132 are respectively connected to the first mounting portion and the second mounting portion, and the sliding seat 141 can be slidably mounted on the mounting shaft 132, and the mounting shaft 132 and the telescopic screw rod 144 are arranged in parallel. Specifically, the mounting member 131 arranges the first mounting portion and the second mounting portion on the mounting member 131 at intervals, and then reliably mounts the mounting shaft 132 through the first mounting portion and the second mounting portion, and then reliably mounts the sliding seat 141 through the mounting shaft 132, so that the sliding seat 141 moves along the axial direction of the mounting shaft 132, and because the mounting shaft 132 and the telescopic screw rod 144 are arranged in parallel, the telescopic screw rod 144 is prevented from interfering with each other relative to the screw rod sleeve 143 and the sliding of the sliding seat 141 on the mounting seat 130, and the precise adjustment of the rice husking gap is facilitated. Optionally, the sliding seat 141 is sleeved on the mounting shaft 132 through a linear bearing 145. Optionally, a plurality of mounting members 131 are provided, and the plurality of mounting members 131 are arranged at intervals on the mounting seat 130, and two adjacent mounting shafts 132 are arranged in parallel, and the sliding seat 141 is supported by the plurality of mounting members 131 at the same time, so as to ensure that the installation of the sliding seat 141 is stable and reliable, and the sliding is smooth.

[0041] like Figure 2 As shown, in this embodiment, the driving member 142 includes a driving motor, a reducer connected to the output end of the driving motor, and a transmission shaft respectively connected to the output end of the reducer and the screw sleeve 143. Specifically, the driving motor provides working power, and then the speed is reduced by the reducer to improve the transmission ratio and ensure transmission stability. Finally, the torque is transmitted through the transmission shaft to drive the screw sleeve 143 to rotate synchronously, thereby driving the telescopic screw 144 to move along the axial direction of the transmission shaft.

[0042] like Figure 6 and Figure 7As shown, the rice husker 100 of this embodiment includes the above-mentioned rice husker rubber roller adjustment device, and the rice husker 100 also includes a supporting base 170, a feeding assembly 180 arranged on the supporting base 170, synchronous transmission belts respectively sleeved on the outside of the movable rubber roller 120 and the fixed rubber roller 110, a driving assembly connected to the synchronous transmission belt at the output end, and a tensioning assembly 190 arranged on the supporting base 170 and connected to the synchronous transmission belt. Specifically, by adopting the above-mentioned rice husking rubber roller adjustment device in the rice husking machine 100, the material is transferred between the fixed rubber roller 110 and the movable rubber roller 120 through the feeding assembly 180, and then the synchronous transmission belt is driven to move through the driving assembly, thereby driving the fixed rubber roller 110 and the movable rubber roller 120 to move, and the tensioning assembly 190 ensures the tensioning of the synchronous transmission belt to ensure stable power transmission, thereby realizing the rice husking operation of the material, and the shelling rate is ensured by the rubber roller adjustment mechanism, the rough crushing rate is reduced, and the service life of the fixed rubber roller 110 and the movable rubber roller 120 is extended. It is highly practical and suitable for wide promotion and application. It should be understood that the fixed rubber roller 110 and the movable rubber roller 120 are wearing parts, so the service life of the fixed rubber roller 110 and the movable rubber roller 120 is extended, that is, the number of replacements of the fixed rubber roller 110 and the movable rubber roller 120 in the same time period is reduced, thereby reducing the processing cost. Optionally, the feeding assembly 180 adopts vibration feeding.

Specifically, after the synchronous transmission belt is sleeved outside the tensioning wheel, the tensioning rod applies an elastic tension force away from the driving assembly to the tensioning wheel, so that the synchronous transmission belt is kept tensioned, thereby stabilizing the power transmission.

[0044] like Figure 6 and Figure 7 As shown, in this embodiment, the rice husker 100 further includes a rotating seat arranged on the support base 170, which is rotatably connected to the rotating seat and connected to the movable rubber roller 120. Specifically, the movable rubber roller 120 is installed by the cooperation of the rotating seat and the rotating shaft, so that the movable rubber roller 120 can be movably arranged on the rice husker 100, and then can move relative to the fixed rubber roller 110 to adjust the rice husker gap.

There are multiple rice husking machines 100, and the multiple rice husking machines 100 are arranged on the main support frame 200 at intervals along the vertical direction, and the germ rice machine 300 is arranged below the multiple rice husking machines 100. Specifically, by using the above-mentioned rice husking machine 100 in the rice husking and milling combination equipment to perform rice husking operations multiple times, the rice husking quality is greatly improved, and then the rice milling operation is performed by the germ rice machine 300 to avoid the transit transportation of brown rice. It should be understood that the specific structure of the germ rice machine 300 belongs to the well-known technology of those skilled in the art, and it is not repeated here. Optionally, multiple rice husking machines 100 share the same feeding assembly 180.
