[0018] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0019] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings:

[0020] Reference Figure 1As shown in the figure, the rice hulling roller is the main accessory of the rice huller and the key equipment for rice husking. Its working principle is that the two rubber rollers rotate at opposite and unequal speeds to allow the rice to enter between the two rollers to squeeze, tear and peel, thereby achieving the purpose of shelling the rice. Most of the existing rice husking rubber rollers will generate temperature due to the friction between them due to long-term shelling of rice. As the temperature continues to rise, the roller surface of the rice husking rubber roller will be worn out quickly. In order to reduce the wear of the rice husking rubber roller, heat dissipation holes and heat conduction methods are opened on the rice husking rubber roller to dissipate heat. Although the temperature on the rice husking rubber roller can be reduced, the heat dissipation effect is general. In order to solve this kind of problem, a reinforced rice husking rubber roller is proposed, including a rubber roller body 1, a cooling groove 152 is opened in the rubber roller body 1, and the cooling groove 152 is located on both sides of the shaft end of the rubber roller body 1. Infusion parts 2 for inputting or outputting cooling liquid into or out of the cooling groove 152 are provided, and a cooling part 15 is provided in the cooling groove 152. The cooling part 15 includes a cooling hole 152 for orderly transmission in the cooling groove 152. The propeller blades 151 of the coolant are arranged at both ends on the side walls of the cooling groove 152. The cooling groove 152 is provided with a heat conduction member on the side of the peripheral wall of the rubber roller body 1 close to the peripheral wall of the rubber roller body 1. The arrangement of the rubber roller body 1 and the cooling groove 152 can achieve the purpose of improving the heat dissipation efficiency of the rubber roller body 1 by providing a cooling structure inside the rubber roller body 1 in the working state. In addition, the arrangement of the infusion member 2 can achieve the purpose of allowing the coolant to enter the cooling groove 152 in an orderly manner and cool the rubber roller body 1 in an orderly transmission state. The arrangement of the propeller blades 151 in the cooling member 15 can ensure the purpose of orderly transmission of the coolant. The arrangement of the heat conduction member can achieve the purpose of conducting heat from the position of the rubber roller body 1 with higher peripheral temperature to the cooling groove 152, thereby achieving the purpose of rapid cooling and heat dissipation, thereby greatly improving the service life of the rubber roller body 1.

[0021] It should be noted that the above-mentioned overall cooling process is specifically as follows: when the rubber roller body 1 is inserted into the rice huller, the two rubber roller bodies 1 pass through the rice directly one after another, and heat is continuously generated between the two. At this time, the infusion part 2 starts to run to input coolant into the cooling groove 152 in the rubber roller body 1. After the coolant enters the cooling groove 152 in an orderly manner, the propeller blade 151 will cause the coolant to flow in an orderly manner along the propeller blade 151 as the rubber roller body 1 rotates, thereby absorbing the heat in the rubber roller body 1 and achieving the purpose of cooling and heat dissipation.

[0022] Furthermore, the specific structure of the above-mentioned infusion component 2 is as follows: the infusion component 2 includes a through groove 12 opened in the axial ends on both sides of the rubber roller body 1, and the two through grooves 12 are respectively provided with a liquid inlet pipe section 21 and a liquid outlet pipe section 22, and the outside of the liquid inlet pipe section 21 and the liquid outlet pipe section 22 extend outward for connection with an external infusion device; through the arrangement of the liquid inlet pipe section 21 and the liquid outlet pipe section 22, the entire coolant delivery process can be made orderly, and through the arrangement of the through groove 12, the purpose of installing the liquid inlet pipe section 21 and the liquid outlet pipe section 22 can be achieved.

[0023] It should be noted that the two axial ends of the rubber roller body 1 are also provided with a transmission shaft 11 for inserting into the rice huller; the transmission shaft 11 is used to connect with the rice huller.

[0024] Additionally, since the rubber roller body 1 is in a rotating state, the above-mentioned liquid inlet pipe section 21 and the liquid outlet pipe section 22 can also be installed by being concentrically arranged with the transmission shaft 11. Specifically, the interior of the transmission shaft 11 is hollow and is used for the arrangement of the liquid inlet pipe section 21 and the liquid outlet pipe section 22.

[0025] It should also be noted that the specific structure of the above-mentioned heat conduction member is as follows: the heat conduction member includes a plurality of heat-conducting blocks 153 arranged on the peripheral wall of the cooling groove 152, and a heat-conducting layer 13 for internal filling of the rubber roller body 1 is provided on the side of the plurality of heat-conducting blocks 153 away from the cooling groove 152; since the outside of the rubber roller body 1 is in the friction area, the heat generated will accumulate on the outer periphery of the rubber roller body 1, and the provision of the heat-conducting layer 13 can achieve the purpose of guiding the heat outside the rubber roller body 1 into the heat-conducting layer 13, and transferring it to the cooling groove 152 through the plurality of heat-conducting blocks 153, so that the coolant transfers the heat away in an orderly manner, thereby achieving the purpose of rapid heat dissipation and cooling of the rubber roller body 1.

[0026] Furthermore, in order to protect the rubber roller body 1, in this embodiment, the outer periphery of the rubber roller body 1 is covered with a protective layer 14, and the protective layer 14 and the heat-conducting layer 13 are arranged in contact with each other; through the arrangement of the protective layer 14, the purpose of the protective layer 14 protecting the outer periphery of the rubber roller body 1 can be achieved.

[0027] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation methods. Any other implementation methods derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
