Description

Technical Field

[0001] The utility model relates to a fast retractable rainproof system for an orchard, in particular to a windproof and rainproof tarpaulin of a fast retractable rainproof shed for an orchard. Background Art

[0002] We know that too much rainfall will reduce the sweetness of mature fruits such as plums, grapes, and peaches, and cause cracks or even breakage on the skin, which will affect the yield and quality of the fruits. In recent years, in order to solve the above problems, technicians have developed a quick-retractable rain shelter for orchards, which can effectively prevent the adverse effects of excessive rainfall on the yield and quality of fruits, and can reduce the use of agriculture and fertilizers.

[0003] The existing orchard quick-retractable rainproof awning includes a support frame, a rainproof tarpaulin and a quick-retractable system. The support frame includes at least three support columns, which are arranged at equal intervals. A transverse support rod is provided in the middle and upper part of the support column. An upper stabilizing wire rope is provided between the upper ends of two adjacent support columns. A left stabilizing wire rope and a right stabilizing wire rope are provided at the left and right ends of two adjacent transverse support rods, respectively. The rainproof tarpaulin includes a rectangular tarpaulin body, a piece of rainproof tarpaulin is provided between two adjacent support columns, a left hanging ring and a right hanging ring are provided on the left and right sides of the tarpaulin body, respectively, and an upper hanging ring is provided in the middle of the tarpaulin body, which is connected to the left and right stabilizing wire ropes. The left hanging ring, the right hanging ring and the upper hanging ring are evenly arranged along the front and rear directions of the tarpaulin body. The left hanging ring and the right hanging ring are respectively hung on the left and right stabilizing wire ropes, and the upper hanging ring is hung on the upper stabilizing wire rope, forming a V-shaped rainproof awning with the opening facing downward. The rapid retraction and release system includes a traction rope and a traction rope driver arranged in a ring shape. The rear side of the tarpaulin body is fixed on the support column and the transverse support rod. The traction rope is fixedly connected to the front side of the tarpaulin body. The traction rope driver is used to drive the annular traction rope to reciprocate. The traction rope drives the rainproof tarpaulin to move forward to open or backward to close.

[0004] The main body material of the rainproof tarpaulin in the existing orchard quick-retractable rainproof awning is mostly plastic cloth. The left and right sides of the tarpaulin main body are respectively connected to the left and right stable steel wire ropes, and the middle part is connected to the upper stable steel wire rope. When the rainproof tarpaulin is opened, a V-shaped rainproof awning with the opening facing downward is formed. This kind of rainproof awning has obvious wind-proof defects. When the wind is strong, the rainproof awning is prone to tilt or even overturn due to excessive force. Utility Model Content
