Description
Technical Field
[0001] The utility model relates to the technical field of rice husker machines, in particular to a rubber roller lifting device for a rice husker machine. Background Art
[0002] Rice husker is a grain processing machine that removes the husk of rice to make brown rice. It can remove the outer shell of rice, reduce the cracking of rice grains and the damage of the skin, and keep the brown rice intact as much as possible. It is mainly composed of a hopper feeding device, a head device, a husk separation chamber, a gear box, a frame, etc. Common rice husker equipment includes rubber roller rice husker, sand disk rice husker and centrifugal rice husker.
[0003] The rubber roller in the rice husker is the main accessory of the rice husker and the key equipment for rice husking. Its working principle is that the two rubber rollers rotate at opposite speeds to allow the rice to enter between the two rollers. Under the action of squeezing, tearing and peeling, the purpose of husking is achieved. The rice husker is mainly made of high-quality natural rubber, silicone or polyurethane and is coated with a special rubber layer on the surface. Therefore, it has excellent wear resistance, corrosion resistance and high temperature resistance, and can withstand long-term use at high temperatures.
[0004] However, the existing rice husking rubber rollers generally adopt a fixed installation method, that is, the rubber rollers can only perform fixed-point positioning operations after installation, and their operating degree is also set according to the initial operating requirements. Although this meets the operating requirements, it is impossible to adjust the grinding degree of grains in real time, resulting in a limited operating scope of the equipment. In addition, for the current rubber rollers, the adjustment method requires personnel to disassemble the installation parts of the roller body to achieve the desired adjustment purpose, but this brings more inconvenience to the personnel's operations and is inconvenient to perform quick adjustment operations;

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1
[0027] In order to solve the technical problems in the background technology, the following rice husker rubber roller lifting device is provided:
[0028] Combination Figure 1-Figure 6 As shown, the rubber roller lifting device of the rice husker provided by the utility model comprises a mounting cover 1 and a casing 2, the mounting cover 1 is fixedly mounted on one side of the casing 2, a receiving and expanding component 8 is dockedly mounted inside the mounting cover 1, a mounting opening 11 is provided on the top of the mounting cover 1, a lifting component 5 is slidably mounted inside the mounting opening 11, the bottom of the lifting component 5 is mounted and connected with the receiving and expanding component 8, a mounting base 6 is dockedly mounted on the lifting component 5 in the mounting cover 1, a first roller body 4 connected with the mounting base 6 is dockedly mounted on the outer side of the casing 2, a material blocking component 3 is fixedly mounted on the first roller body 4, and the material blocking component 3 is in contact with the outer wall of the casing 2;
[0029] During this period, the mounting cover 1 is installed on the outside of the machine casing 2 of the equipment. The first roller body 4 can be raised and lowered in real time by the lifting component 5, so that the distance between the first roller body 4 and the roller group reaches the required gap to meet the equipment's processing needs for grains. The expansion component 8 can not only ensure that the height between the roller bodies is adjusted, but also the roller bodies can be adjusted laterally, so that the roller bodies can be adjusted in real time according to the actual processing objects and needs of the equipment. The material blocking component 3 cooperates with the adjusted roller body, which can not only ensure the normal adjustment of the roller body, but also block the material when the roller group is operating, thereby avoiding the leakage of impurities from the adjustment gap when the equipment removes the chaff of the grains, thereby ensuring the sealing effect between the device and the equipment.
[0030] The material blocking assembly 3 includes a rubber inner pad 31 and a material blocking plate 32. The inner end of the first roller body 4 is fixedly installed with the material blocking plate 32, and the inner side of the material blocking plate 32 is fixedly installed with a rubber inner pad 31 that is in contact with the casing 2. The lifting assembly 5 includes a first threaded adjustment rod 51, a guide rod 52, and a base block 53; the expansion assembly 8 includes a lower guide seat 81 and a second threaded adjustment rod 82. The second threaded adjustment rod 82 is connected to the mounting cover 1 and connected to the mounting cover 1. The lower guide seat 81 is mounted on the second threaded adjustment rod 82. The base block 53 is slidably installed inside the mounting port 11, and the first threaded adjustment rod 51 and the guide rod 52 are connected to the base block 53 respectively. The bottom ends of the first threaded adjustment rod 51 and the guide rod 52 pass through the mounting base 6 and are connected to the top of the lower guide seat 81.
[0031] During this period, if it is necessary to perform lifting and lowering adjustment, the personnel can rotate the first threaded adjustment rod 511, and with the cooperation of the guide rod 52, the mounting base 6 is prompted to perform lifting and lowering movement. At that time, the first roller body 4 mounted on the mounting base 6 and the material blocking assembly 3 are synchronously adjusted in real time to achieve the required height adjustment, which is longitudinal adjustment. If lateral adjustment is required, the personnel can rotate the second threaded adjustment rod 82. At that time, the lower guide seat 81 is driven by the driving force to move itself in real time, and the mounting base 6 and the longitudinal adjustment member on the lower guide seat 81 will move synchronously to achieve spacing adjustment. At the same time, it should be noted that an assembly port corresponding to the mounting cover shell 1 is provided on the casing 2 to ensure the extended installation and adjustment operation of the component. During operation, the material blocking plate 32 is fitted with the shell wall of the casing 2 through the rubber inner pad 31. The purpose is to block the assembly port while preventing grain husks from entering the device through the assembly port. Embodiment 2
