Abstract

The invention discloses an automatic control system of rainproof cloth for an open grain stack. The automatic control system includes a contraction and expansion mechanical structure and a control system, the contraction and expansion mechanical structure includes an outer tooth ring fixedly arranged on the outer edge of the top end of the cylindrical grain stack, a gear connected with the outer tooth ring in an engaged mode and driven by a stepping motor, and a rainproof cloth reel fixedly mounted with the gear in the same axle center and parallel to the axis of the grain stack, one edge of the rainproof cloth is fixed to the circumferential outer wall of the cylindrical grain stack, and the other edge of the rainproof cloth is fixed to the rainproof cloth reel.

Description

technical field [0001] The invention relates to the technical field of mechanical automation, in particular to an automatic control system for rainproof cloth for open-air grain stacks. Background technique [0002] After crops such as wheat, rice, corn and soybeans are matured and harvested, they are sent to grain depots for storage in the form of grain stacks. Open-air grain stacks are a well-ventilated storage method that can effectively prevent grain from becoming moldy. However, open-air grain stacks also have certain disadvantages. For large-scale grain stacks, workers need to climb up to cover the rainproof cloth on the top of the grain stacks, which poses a safety hazard. Contents of the invention [0003] The purpose of the present invention is to provide an automatic control system for rainproof cloth for open-air grain stacks, which can replace manual work and automatically roll and unwind the rainproof cloth. [0004] The technical scheme adopted for realizin...
