Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a compound full-automatic rubber-roller rice husker. Background Art

[0002] The rubber roller rice husker is an important rice husking equipment in rice processing. Its performance directly affects the process effect of subsequent procedures, and also affects the quality, yield, crushing rate and yield of finished rice. The rubber roller rice husker is mainly composed of a feeding mechanism, a roller, a roller pressure adjustment mechanism, an automatic tension roller mechanism, a transmission mechanism, a husk separation device and other parts. Its main working component is a pair of rubber rollers that rotate in opposite directions at different speeds. The two rubber rollers are arranged at a certain angle on the same horizontal plane. One roller is fixed and the other roller is set to be movable. When not working, the two rollers are separated by the tension roller mechanism. When working, the two rollers are close together and maintain a certain gap (rolling distance). The rolling distance between the two rollers is adjustable. The rubber roller rice husker adopts the working principle of differential roller pairs, and rotates the two rollers in different directions and speeds. When working, the two rubber rollers are close together to form a working area, and apply extrusion and friction to the grains entering the working area between the two rubber rollers, which produces a tearing effect to break the rice husk and separate it from the brown rice, thereby achieving husking.

[0003] After exploration and analysis, the following shortcomings exist in actual use:

[0004] The existing grain processing hulling devices have low working efficiency, and when hulling the grains, the hulling operation is usually performed by wind selection. Even after wind screening, some small particles and dust may still remain in the grains, and the screening efficiency is low.

[0005] In summary, the present application now proposes a compound fully automatic rubber roller rice husker to solve the above-mentioned problems. Utility Model Content

[0006] The utility model aims to provide a compound full-automatic rubber roller rice husker, which can solve the problem that some small particles and dust may remain in the grains.

[0007] In order to achieve the above object, the utility model provides the following technical solution: a compound fully automatic rubber roller rice husking machine, comprising:

[0008] The box body has a bottom frame fixedly mounted on the bottom of the box body;

[0009] A screening component is arranged on the box body;

[0010] The screening component is arranged on the bottom frame, and comprises a slide rail, a connecting slider and a hydraulic rod. The slide rail is fixedly installed on the inner top of the bottom frame, the connecting slider is slidably installed on the box body, and the hydraulic rod is fixedly installed on one side outer wall of the bottom frame.

[0011] Preferably, two groups of shell-breaking rollers are rotatably installed on the front and rear inner walls of the box and are symmetrically distributed, and a driving device is fixedly installed on the rear outer wall of the box. The driving device drives the two groups of shell-breaking rollers to rotate, and the rice is shelled by the two groups of shell-breaking rollers rotating towards each other.

[0012] Preferably, the screening assembly includes a guide plate and a vibration motor. The guide plates are fixedly installed on the inner walls on both sides of the box body, and the vibration motor is fixedly installed on the bottom of the guide plate. The setting of the guide plate can effectively block large particles, impurities and foreign matter in the grains, ensuring that only clean grains pass through, which helps to improve the quality of the grains and reduce the risk of contamination in subsequent processing stages. The rice that falls after vibration is more susceptible to the effect of wind, making the wind screen more efficient, helping to more thoroughly remove small particles, dust and other tiny impurities, and improving the purity of the grains.

[0013] Preferably, a fan is fixedly mounted on an inner wall of one side of the box, a triangular baffle is fixedly mounted on the bottom of the box, which can separate the rice from the rice husk, and an opening is provided on the inner bottom of the box.

[0014] Preferably, two groups of movable plates are provided inside the bottom frame and are symmetrically distributed, a filter frame is provided between the two groups of movable plates, adjacent side walls of the two groups of movable plates are fixedly installed with sliding blocks, and sliding grooves are provided on the outer walls on both sides of the filter frame. The sliding blocks are slidably installed in the sliding grooves. The filter frame is easy to disassemble and install, thereby facilitating the retrieval of the collected rice.

[0015] Preferably, the screening assembly also includes a spring, a spring is fixedly installed on one side of the movable plate, the other end of the spring is fixedly installed on the inner wall of one side of the bottom frame, one side of the connecting slider is fixedly installed on the other side of the movable plate, and the free end of the hydraulic rod passes through the bottom frame and is fixedly installed on one side of the movable plate. After wind screening, there may still be some small particles and dust remaining in the grains. By shaking and screening again, these tiny impurities can be further removed to improve the purity of the grains. Shaking and screening can make the grains evenly distributed on the filter frame to avoid accumulation or agglomeration of grains, which helps to improve the uniformity of screening, ensure that every grain can fully contact the screen, improve the screening effect, reduce the risk of screen blockage, extend the service life of the screen, and help improve the consistency of product appearance.

[0016] Preferably, a collecting frame is placed at the inner bottom of the bottom frame to facilitate the collection of the screened impurities.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] (1) The compound fully automatic rubber roller rice husker uses a guide plate and a vibration motor in combination. The guide plate can effectively block large grains, impurities and foreign matter in the grains, ensuring that only clean grains pass through, which helps to improve the quality of the grains and reduce the risk of contamination in the subsequent processing stages. The rice that falls after vibration is more susceptible to the effect of wind, making the wind screen more efficient, helping to more thoroughly remove small particles, dust and other tiny impurities, and improving the purity of the grains.

[0019] (2) The compound fully automatic rubber roller rice husker uses springs, slide rails, connecting sliders and hydraulic rods. After wind screening, there may still be some small particles and dust remaining in the grains. By shaking and screening again, these tiny impurities can be further removed to improve the purity of the grains. Shaking and screening can make the grains evenly distributed on the filter frame to avoid grain accumulation or agglomeration, which helps to improve the uniformity of screening and ensure that every grain can fully contact the screen, thereby improving the screening effect, reducing the risk of screen blockage, extending the service life of the screen, and helping to improve the consistency of product appearance.
