  A pressure-receiving arm 97 is pivotally supported on the pressure-removing case 80 so that the pressure-receiving arm 97 supports the pressure-reducing pressure adjusting screw shaft 95 and is also in contact with the pressure-receiving arm 97. And a deployment cam 98 is rotated by operating the deployment lever 99 so that the other release roller 30 on the movable shaft 94 is moved relative to the one release roller 30 on the fixed shaft 91. The detachment pressure adjusting screw shaft 95 is moved in the direction of separation, and the detachment pressure adjusting arm 92 is moved to a position where the other detachment roller 30 on the movable shaft 94 is largely separated from the one detachment roller 30. It is configured so that, when each detaching roller 30 is worn, the detaching roller 30 is not worn.

  On the other hand, a tension pulley 111 is provided for tensioning the detachment driving belt 29 wound around the detachment driving pulley 28 and the detaching driven pulley 31. One end of the tension arm 113 is pivotally supported on the removal case 80 via a fulcrum shaft 112, and the tension pulley 111 is pivotally supported on the other end of the tension arm 113. Further, the bearing bracket 114 is fastened and fixed to the removal case 80, and the support shaft 115 is pivotally supported on the bearing bracket 114. The rod support arm 116 and the linkage arm 117 are integrally fixed to the support shaft 115. Both ends of a tension adjusting rod 119 that can be expanded and contracted by a tension spring 118 are connected to the tension arm 113 and the rod support arm 116 by engaging pin bodies 120 and 121. A tension spring 118 is wound around a tension adjustment rod 119 that can be expanded and contracted.

  That is, the tension adjusting rod 119 is extended by the tension spring 118, and the removal driving belt 29 is tensioned by the tension pulley 111. In addition, both ends of the linkage rod 122 are connected to the release pressure adjusting arm 92 and the linkage arm 117 by engagement pin bodies 123 and 124. Therefore, by rotating the operation knob 96, the depressurization pressure adjusting screw shaft 95 is rotated, and the depressurization pressure adjusting arm 92 is swung around the support shaft 93, so that one deroller roller 30 on the fixed shaft 91 is swung. When the other detaching roller 30 on the movable shaft 94 is brought into and out of contact with each other and the hulling interval (depressing pressure) of the pair of detaching rollers 30 is adjusted, the linking rod is oscillated by the detaching pressure adjusting arm 92. The tension adjusting rod 119 is pushed and pulled via 122.

  As a result, the deflation pressure adjusting arm is adjusted so that the tension of the detachment drive belt 29 changes when the hulling interval (desorption pressure) of the pair of detachment rollers 30 is adjusted by rotating the operation knob 96. The detachment driven pulley 31 is brought into contact with and separated from the detachment driving pulley 28 by the swing of 92, but the tension pulley 111 (tension arm 113) is displaced in conjunction with the rotation operation of the operation knob 96, and the detachment driving belt. Thus, the tension of 29 is maintained at a predetermined value.

  As shown in FIGS. 1 and 14 to 20, a pair of release rollers 30 driven via a release drive belt 29 as a belt transmission mechanism, and another release roller with respect to one release roller 30. In the grain adjustment device that includes a detachment pressure adjusting arm 92 as a detachment link mechanism that contacts and separates 30 and removes the rice husk from the cocoon by each of the detachment rollers 30, The tension adjusting rod 119 as a tension adjusting member of the detachment driving belt 29 is connected, and the tension of the detachment driving belt 29 can be adjusted by the detachment pressure adjusting operation of the detachment pressure adjusting arm 92. The detaching pressure of the detaching roller 30 can be adjusted while keeping the tension of the detaching driving belt 29 constant. There is no need to operate the tension adjusting rod 119 correspondingly when adjusting the detaching pressure of the detaching roller 30. Depressurization pressure adjustment operability can be improved. Problems such as forgetting to operate the tension adjusting rod 119 can be eliminated, and the removal function of the removal roller 30 can be properly maintained.

  As shown in FIGS. 15 to 20, a tension pulley 111, a tension arm 113, and a tension adjustment rod 119 are provided as tension adjustment members, and one end side of the tension adjustment rod 119 is connected to the tension arm 113. One end side of the tension operation rod 119 is connected to the end side via the rod support arm 116 and the linkage arm 117 as an operation link body, and the decompression pressure adjusting arm 92 is connected to the other end side of the tension operation rod 119. Therefore, the tension operation rod 119, the rod support arm 116, and the linkage arm 117 have a structure in which the tension adjustment of the detachment driving belt 29 as a belt transmission mechanism and the detachment pressure adjustment of the detaching roller 30 are interlocked. Easy to configure.

  As shown in FIGS. 18 to 20, a tension spring 118 is wound around a tension adjustment rod 119 that can be expanded and contracted, and the tension arm 113 can be elastically pressed by the tension spring 118 force. The tension force of the detachment drive belt 29 of the detachment drive belt 29 can be stably obtained by the tension spring 118, and the extension of the detachment drive belt 29 over time can be easily dealt with.
