[0020] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. The same parts are represented by the same figure marks. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom" and "top", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0021] like Figures 1 to 4 As shown, a rubber roller 2 for a rice husker comprises a driving shaft 1 and a rubber roller 2. The driving shaft 1 is provided with conventional bearing seats, fast roller pulleys, slow roller pulleys, roller change clutch, cylinders, and large cylinder bearings. These components ensure that the driving shaft 1 can be connected to an external power source, so that the driving roller can drive the rubber roller 2 to start rotating.

[0022] The rubber roller 2 is connected to the outside of the driving shaft 1 by sleeve connection. There are a cap 4 and a rubber roller seat 3 at both ends of the rubber roller 2. The rubber roller seat 3 is located on the side of the rubber roller 2 close to the bearing seat, and the rubber roller seat 3 is fixedly connected to the driving shaft 1. After the rubber roller 2 is sleeved onto the driving shaft 1, the rubber roller seat 3 will abut against one side of the rubber roller 2. The cap 4 and the driving shaft 1 are detachably connected. After the rubber roller 2 is installed on the driving shaft 1, the cap 4 is fixed on the driving shaft 1 so that the cap 4 abuts against the other side of the rubber roller 2. The cap 4 and the rubber roller seat 3 are truncated cone-shaped as a whole. The side walls of the cap 4 and the rubber roller seat 3 are inclined surfaces. The smaller end thereof is inserted into the rubber roller 2 until the larger end of the cap 4 and the rubber roller seat 3 is on the same plane as the side of the rubber roller 2. At this time, the cap 4 and the rubber roller seat 3 realize the clamping and fixing of the rubber roller 2.

[0023] A fixing plate 5 is fixedly provided on one side of the driving shaft 1 close to the cap 4. The fixing plate 5 is fixedly connected to the driving shaft 1, that is, the cap 4 will not be separated from the driving shaft 1 only by connecting the cap 4 and the fixing plate 5, so that the cap 4 can fix the rubber roller 2. An annular groove 1 is provided on the driving shaft 1, and two half-moon blocks 9 are provided on one side of the fixing plate 5. The two half-moon blocks 9 are semicircular rings of the same size. The two half-moon blocks 9 are used to combine into a complete ring. The ring formed by the two half-moon blocks 9 will be on the annular groove 1. Since the diameter of the annular groove 1 is smaller than the diameter of the two sides thereof, the two half-moon blocks 9 cannot move on the driving shaft 1 after being combined. Annular groove 2 is provided at the center position of the fixed plate 5 close to the fixed flange 7. The two half-moon blocks 9 are all submerged in the annular groove 2. The half-moon blocks 9 are used to stabilize the fixing plate 5 so that the fixing plate 5 will not shake.

[0024] A fixed flange 7 is also provided on the driving shaft 1, and the fixed flange 7 is fixed on the driving shaft 1. The diameter of the fixed flange 7 is smaller than the diameter of the fixed plate 5, the fixed flange 7 is in contact with the fixed plate 5, and the fixed flange 7 is located on the side of the fixed plate 5 close to the rubber roller seat 3. A plurality of corresponding fastening holes 8 are provided on the fixed flange 7 and the fixed plate 5, and the fixed plate 5 can be fixed to the fixed flange 7 by passing fasteners such as screws through the fastening holes 8, thereby enhancing the stability of the fixed plate 5.

[0025] A plurality of fastening holes 6 are provided at corresponding positions of the cap 4, the fixing plate 5 and the fixing flange 7. The cap 4 can be fixed to the fixing plate 5 and the fixing flange 7 by passing fasteners such as bolts through the fastening holes 6, so that the cap 4 can fix the rubber roller 2. The cap 4 is in a truncated cone shape, and the side wall of the cap 4 is an inclined surface. When the cap 4 is pressed against one end of the rubber roller 2, the side wall of the cap 4 will generate a thrust on the rubber roller, so that the end of the rubber roller 2 that contacts the cap 4 is pressed tightly, and the force generated when the rubber roller 2 vibrates will be evenly distributed to various positions of the cap 4, so that the fasteners at the cap 4 are not easily loosened by vibration.

[0026] A plurality of guide posts 10 are also provided on the side of the driving shaft 1, and the plurality of guide posts 10 are arranged parallel to the driving shaft 1. The two ends of the guide post 10 are respectively a threaded end 11 and a telescopic end 12, and the threaded end 11 is provided with a thread, and the threaded end 11 is threadedly connected with the threaded hole on the rubber roller seat 3. The telescopic end 12 can be retracted into the guide post 10, and a spring is provided in the guide post 10, and the spring can reset the telescopic end 12. By utilizing this characteristic, the telescopic end 12 can be inserted into the plug hole on the fixed plate 5. When the rubber roller 2 is inserted into the driving shaft 1, the inner wall of the rubber roller 2 will be in contact with the plurality of guide posts 10, and the plurality of guide posts 10 make the rubber roller 2 always remain in a state parallel to the driving shaft 1, so that one end of the rubber roller 2 can be smoothly sleeved on the rubber roller seat 3.

[0027] One part of the rubber roller seat 3 is cylindrical, and the other part is truncated. The cylindrical part of the rubber roller seat 3 is located and fixed at the smaller end of the truncated cone of the rubber roller seat 3, and the distance between the cylindrical part of the rubber roller seat 3 is the same as the distance between the smaller end of the truncated cone. One end of the rubber roller 2 will first be sleeved on the cylindrical part of the rubber roller seat 3, and then as the rubber roller 2 continues to move, one end of the rubber roller 2 will move along the side wall of the truncated cone of the rubber roller seat 3 until the rubber roller seat 3 is completely sleeved. A flat key is provided on the rubber roller seat 3, so that the rubber roller seat 3 can drive the rubber roller 2 to rotate, increasing the stability of the rubber roller 2 when working.

[0028] A flat key is also provided on the driving shaft 1 so that the driving shaft 1 can drive the rubber roller seat 3 to rotate.

[0029] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
