Until the second outer circumferential surface 643 of the driven pulley 64 contacts the belt 65, the piston rod extension of the tensioning cylinder 922 should be matched to the piston rod extension of the adjusting cylinder 9 to ensure that the belt 65 can be kept tensioned.
As shown in fig. 17 to 18, the transmission unit further includes a supporting cylinder 93, the supporting cylinder 93 is fixedly connected with the tray 1 relatively and is sleeved on the second rotating shaft 5', the supporting cylinder 93 is provided with a bearing 98, the second rotating shaft 5' extends into an inner ring of the bearing 98, and the supporting cylinder 93 is further rotatably connected with the second rotating shaft 5 '. The support cylinder 93 has a tapered hole 931 and a circular hole 932 inside, the circular hole 932 being for contact with the first outer circumferential surface 641, the tapered hole 931 being for contact with the tapered surface 642. When the first outer circumferential surface 641 and the tapered surface 642 of the driven pulley 64 partially extend into the support cylinder 93, the support cylinder 93 supports the driven pulley 64.
As shown in fig. 18, the transmission unit further includes a positioning mechanism, the positioning mechanism includes a positioning block 97, a support 94, a guide rod 95 and a positioning spring 96, one end of the support 94 is fixedly connected with the side wall of the supporting cylinder 93, the guide rod 95 is radially arranged along the driven pulley 64, one end of the guide rod 95 is slidably connected with the other end of the support 94, the other end of the guide rod 95 is slidably connected with the positioning block 97, the positioning spring 96 is arranged between the other end of the support 94 and the positioning block 97, the outer wall of the transmission belt 65 is provided with an annular protrusion 67, and the protrusion 67 is enabled to extend into a positioning groove 971 on the positioning block 97 under the action of the positioning spring 96, so that the axial positioning between the transmission belt 65 and the driving pulley 63 and the axial positioning between the transmission belt 65 and the driven pulley 64 along the pulleys (the driving pulley 63 or the driven pulley 64) are realized. In order to realize the relative fixing along the circumferential direction and the relative sliding connection along the axial direction between the driven pulley 64 and the second rotating shaft 5', as shown in fig. 19, one end of the second rotating shaft 5' extending into the driven pulley 64 is a square section 51, and correspondingly, a square jack in plug-in fit with the square section 51 is arranged in the driven pulley 64. When the driving belt 65 moves along the conical surface 642 to the second outer circular surface 643, the driving belt 65 moves radially outwards along the driven pulley 64, at this time, the elastic force of the positioning spring 96 is overcome, and the positioning spring 96 is compressed, so that the positioning block 97 moves radially outwards along the driven pulley 64, and the positioning block 97 keeps contact with the driving belt 65 under the action of the positioning spring 96, so that the driving belt 65 is prevented from being dislocated to cause separation from the driving pulley 63.
The invention respectively places two kinds of crop seeds for intercropping by arranging the first type box and the second type box in different rows, is used for meeting the requirements of different kinds of crops in combination intercropping by arranging the variable type box, is suitable for intercropping of two kinds of crops with the same sowing width when the seeds which are the same as the first type box are placed in the variable type box and are arranged between every two adjacent rows of first crops, and is suitable for intercropping of two kinds of crops with the same sowing width when the seeds which are the same as the second type box are placed in the variable type box, and is suitable for intercropping of two kinds of crops with different sowing widths, such as corn and soybean. The transmission unit has the function of adjusting the transmission ratio, so that the rotating speeds of the first rotating shaft and the second rotating shaft are adjusted, and the plant spacing during sowing is further adjusted. The row spacing adjusting unit is arranged, so that the row spacing between the first crop and the second crop, between the two rows of the first crop and between the two rows of the second crop after sowing can be adjusted, and the intercropping sowing requirements of different types of combined crops can be further met.
