Description

Technical Field

[0001] The utility model relates to the technical field of rice husker machines, in particular to a rubber roller rice husker machine. Background Art

[0002] The process of rice processing can be divided into rice cleaning, rice husking and separation of husking materials, rice milling and finished product sorting. The rice husking machine is a grain processing machine that husks rice and makes brown rice. The commonly used one is the rubber roller rice husking machine. The main working parts of the rubber roller rice husking machine are a pair of horizontal rubber rollers or plastic rollers bonded or covered with rubber layers on the cast iron cylinder. The axes of the two rollers are located in the same horizontal plane or have a slight height difference. They rotate in opposite directions at different speeds. One of the rollers is fixed and the other roller can be moved, so that the rolling distance between the two rollers can be adjusted. The rice is evenly rolled over the entire length of the rubber roller by the flow plate. The rice is fed between two rollers, and the rollers of equal diameter rotate in opposite directions at different linear speeds. The pressure of the pressure weight squeezes and tears the rice passing between the rollers. Due to the squeezing of the two rollers and the tearing effect caused by the speed difference between the two rollers, most of the rice is husked and enters the husk separation device. During the operation of the rubber roller husker, the rubber roller will be worn due to squeezing and friction and needs to be replaced frequently. The existing method of replacing the rubber roller requires disassembling the entire machine and the entire rubber roller part, which is complicated to operate and very inconvenient. In view of this, we propose a rubber roller husker to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to provide a rubber roller rice husker to solve the problems raised in the above background technology.

[0004] To achieve the above object, a rubber roller rice husker is provided, comprising a shell, a feed port is arranged above the shell, a motor is arranged on the side of the shell, a base is arranged below the motor, an output shaft is arranged on the side close to the shell, two belts are arranged on the output shaft, a rotating roller is arranged at one end of the belt away from the output shaft, the rotating roller penetrates the shell and extends to the inside of the shell, a discharge port is arranged at the lower part of one side of the shell away from the motor, a flow plate is arranged below the feed port inside the shell, a rubber roller is arranged on the rotating roller below the flow plate, a plurality of grooves are arranged in the grooves at both ends of the rubber roller, and a plurality of fixing blocks are arranged in the grooves;

[0005] It also includes two fixed plates, namely a first fixed plate and a second fixed plate, which are respectively connected to the fixed blocks in the grooves at both ends of the rubber roller. The first fixed plate is fixedly connected to the rotating roller near one end of the motor, and a card slot is provided on the rotating roller, and a fixing device is provided on the card slot.

[0006] As a further improvement of the present technical solution, the fixing device includes a support plate, a pull rod is arranged at the center position of the support plate, the pull rod passes through the support plate and extends to the other side of the support plate, the support plate is slidably connected to the pull rod, a clamping block is arranged at one end of the pull rod near the clamping slot, and a first spring is arranged between the clamping block and the support plate.

[0007] As a further improvement of the technical solution, a hollow block is arranged on the support plate, a moving block is arranged inside the hollow block, the moving block is slidably connected to the hollow block, and a second spring is arranged inside the hollow block.

[0008] As a further improvement of the technical solution, a machine door is arranged on the upper part of a side of the shell away from the motor, a window is arranged on the upper part of the machine door, and a handle is arranged below the window.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1. In the rubber roller rice husker, by adding a window, the staff can directly observe the working condition and wear condition of the rubber roller without stopping the machine and disassembling the shell to check the rubber roller; adding a machine door allows the machine to be opened directly when replacing the rubber roller without removing a large number of screws, which makes it convenient for the staff to open the shell, saves time and manpower, and improves work efficiency.

[0011] 2. In the rubber roller rice husker, a fixing device is added. By pulling the pull rod on the fixing device, the block and the slot can be separated. The rubber roller can be easily taken out by taking out the fixing block and replaced with a new one. This avoids the traditional method of removing the entire rubber roller, unscrewing the screws, and then knocking with a hammer to remove the rubber roller, which is a cumbersome operation. After the improvement, the rubber roller can be easily replaced, which greatly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
