Description

Technical Field

[0001] The utility model belongs to the technical field of grain coolers, in particular to an automatic dust and rain proof device for a grain cooler. Background Art

[0002] Grain cooler is a kind of mechanical equipment specially designed for grain storage industry. Its main function is to cool down the stored grains (such as wheat, corn, rice, etc.). It can also regulate the humidity of grains to inhibit mold growth, prevent pests, slow down metabolism and maintain grain quality. This equipment usually includes refrigeration system, ventilation system and intelligent control system to ensure long-term safe storage of grains under suitable temperature and humidity conditions. The automatic dust and rain protection device of grain cooler is an additional component designed to protect the equipment from dust and rain erosion.

[0003] The existing automatic dust and rain proof device of the grain cooler fixes the dust and rain proof folding plate with bolts. Once the dust and rain proof folding plate is worn or damaged due to long-term use, it cannot be replaced quickly. The bolts need to be unscrewed one by one to replace the damaged parts, which increases the time and labor costs of maintenance. In addition, rainwater will corrode the bolts, causing them to rust and become unable to be disassembled. Utility Model Content

[0004] In view of this, the utility model aims to solve the shortcomings of the prior art and provide an automatic dust and rain proof device for a grain cooler. The dust and rain proof folding plate can be quickly replaced through a quick disassembly mechanism without the aid of external tools, which can simplify the maintenance process, shorten the maintenance time, and improve the maintenance efficiency. At the same time, it also prevents the bolts from rusting and becoming unable to be disassembled.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] First, by installing the dustproof placement device on the fan of the grain coolant and controlling the raindrop sensor to turn on the operation through the control panel, when the raindrop sensor senses rain, the raindrop sensor feeds back the signal to the control panel, and the control panel controls the motor to turn on the operation. The output shaft rotates to drive the screw rod to rotate, so that the sliding installation frame moves to the left and drives the dust and rainproof folding plate inside it to extend, so that the fan on the grain cooler can be covered, and the grain cooler can be quickly protected from rain.

[0011] Secondly, when the grain cooler is not used for a long time, the staff can manually control the motor to be turned on through the control panel, so that the dust and rainproof folding plate is extended to cover the fan on the grain cooler, which can quickly realize dust prevention of the grain cooler.
