[0002] Grain refers to the general term for various plant seeds in cooking foods, and can also be generally referred to as "cereals". Grain crops are rich in nutrients, mainly including protein, vitamins, dietary fiber, fat, starch, etc. Schools, enterprises, and company canteens need to store a large amount of agricultural products for easy access at any time. Grain is also a kind of agricultural product, so a grain storage device is needed to store grain.

[0003] The existing grain storage devices are usually in a sealed state to prevent mosquitoes from entering. However, during long-term storage of grain, the existing grain storage devices will be affected by the surrounding environment, causing the grain to get damp and deteriorate, thus attracting mosquitoes. Although the existing grain storage devices have an air circulation mechanism, it requires an additional driving source to drive the internal gas circulation, resulting in an increase in the device cost.

[0015] Working principle: When using this device, the grain needs to be loaded into the grain storage box through the feeding pipeline. Then, by starting the second motor, the screw rod is driven to rotate inside the conveying pipeline, and the baffle is pulled upward. In this way, the grain inside the grain storage box can be carried into the storage barrel through the inside of the conveying pipeline, thus conveniently placing the grain into the storage barrel;

[0016] By starting the first motor, the rotating rod can be driven to rotate, so that multiple stirring blades flip the grain inside the storage barrel. During the rotation of the rotating rod, the semi-gear is driven to rotate synchronously. Under the mutual cooperation of the semi-gear and the rack, the rack can move along the outside of the two limit blocks, thereby driving the moving rod to move synchronously. Under the limiting action of the limit collar, the moving rod moves more smoothly, thus driving the piston to move inside the sleeve. When the semi-gear rotates to the other side, under the action of the spring, the piston is pushed to reset, thereby pushing the gas inside the sleeve into the storage barrel through the air outlet pipe and opening the exhaust valve, then accelerating the gas circulation inside the storage barrel. And with the flipping action of the stirring blades, the grain inside the storage barrel can be kept dry. Filters are provided at the pipeline, which can prevent mosquitoes from entering the storage barrel;

[0017] By starting the heating pump, gas can be extracted through the heating suction pipe for heating and then transported to the storage barrel through the heating pipe, so as to heat the inside of the storage barrel. By starting the cooler, gas can be extracted through the cooling suction pipe for cooling and then transported to the storage barrel through the cooling pipe, so as to cool the inside of the storage barrel. In this way, through the mutual cooperation of the cooler and the heating pump, the temperature inside the storage barrel can be kept stable, thus prolonging the storage time of the grain. When the grain inside the storage barrel needs to be taken out, by opening the control valve, the grain inside the storage barrel can enter the collection box through the collection pipeline.

[0018] The present invention provides a grain storage device for moisture-proof and insect-proof, which has the following beneficial effects:

[0019] 1. By starting the first motor of the present invention, the rotating rod is driven to make multiple stirring blades flip the grain inside the storage barrel, and the semi-gear rotates synchronously, so that the rack drives the moving rod to move. During the movement of the moving rod, the piston is driven to move inside the sleeve. When the semi-gear rotates to the other side, the spring pushes the piston to reset, so that the gas inside the sleeve enters the storage barrel through the air outlet pipe, thereby accelerating the gas circulation inside the storage barrel, effectively keeping the grain dry, preventing mildew, and being able to effectively prevent the invasion of mosquitoes and the like, maintaining the safety and hygiene of the grain.

[0020] 2. By starting the heating pump, the extracted gas is heated and then transported to the inside of the storage barrel through the heating pipe, thereby raising the temperature inside the storage barrel. By starting the cooler, the extracted gas is cooled and then transported to the inside of the storage barrel through the cooling pipe, thereby lowering the temperature inside the storage barrel. The mutual cooperation of the heating pump and the cooler can keep the temperature inside the storage barrel stable, which helps to extend the effective storage time of grains, reduce the risk of deterioration and loss, and adapt to different storage requirements through the adjustment of heating and cooling according to the changes in the external environment.

[0021] 3. By starting the second motor, the screw rod is driven to rotate inside the conveying pipe, so that the grains in the grain storage box are transported into the storage barrel. Cooperating with the opening of the control valve, the grains inside the storage barrel flow out to the inside of the collection box due to gravity. In this way, the grains can be conveniently transported into the storage barrel, reducing the need for manual use of other machines for transportation. BRIEF DESCRIPTION OF THE DRAWINGS
