Description

Annular belt tensioning and adjusting device for crop vine falling device Technical Field The utility model relates to the technical field of crop vine falling, in particular to an annular belt tensioning and adjusting device for a crop vine falling device. Background When planting vining crops, such as cucumbers, loofah, tomatoes and the like in a greenhouse, a lifting rope is tied in the greenhouse, and the vines of the crops are lifted through the lifting rope. The height of crops is controlled by the lifting rope so as to facilitate the farmers to manage the crops. Because the whole growth management period of crops is longer, the lifting height of the vines needs to be adjusted for multiple times during the vine lifting period. The height of the vines is reduced by falling the vines for a plurality of times, so that the operations of picking flowers, dotting flowers, picking stubble and the like can be conveniently performed manually. The traditional adjustment mode is that the vine is taken down from the lifting rope through manual work many times, and after the height of the vine is reduced, the vine is lifted again from the new vine, which is time-consuming and labor-consuming. Because the vines of crops are generally longer, the vines are easy to break in the process of falling the vines for many times, and the production of the crops is affected. Meanwhile, manual rope falling is required to be manually detached and assembled, a large amount of physical power is required to be consumed in the whole process, and the working efficiency is low. In summary, it is clear that the prior art has inconvenience and defects in practical use, so that improvement is needed. Disclosure of utility model Aiming at the defects, the utility model aims to provide the annular belt tensioning and adjusting device for the crop vine falling device, which can be repeatedly used, shortens the vine falling time, improves the vine falling efficiency, can meet the use requirements of different crops, and expands the application range of the device. The utility model provides an annular belt tensioning adjusting device for a crop vine falling device, which comprises fixing plates arranged at the top of a greenhouse, wherein two ends of each fixing plate are respectively and rotatably connected with side adjusting plates, guide supporting wheels are respectively and rotatably arranged on the side adjusting plates, a hanging rope main hanging shaft and a driving shaft are respectively and rotatably connected between the fixing plates, a plurality of hanging ropes are connected onto the hanging rope main hanging shaft, an annular belt matched with the guide supporting wheels is arranged below the hanging rope main hanging shaft, hanging rope hooks matched with the hanging ropes are arranged on the annular belt, an adjusting piece and a tensioning piece are connected onto the driving shaft in a threaded manner, driven pieces are respectively and rotatably arranged on the fixing plates on two sides of the driving shaft, adjusting connecting rods are respectively and rotatably arranged between the adjacent adjusting pieces and the driven pieces, driven connecting rods are respectively and rotatably arranged between the adjacent driven pieces and the side adjusting plates, and tensioning supporting wheels matched with the annular belt are respectively arranged below the tensioning piece.
