Description

Technical Field

[0001] The present invention relates to the field of machinery, and particularly to a multi-purpose high-moisture grain dehumidifying device. Background Art

[0002] When storing or purchasing grains in a granary, there are often grains with high moisture content, which do not meet the requirements for grain storage or purchase. Measures must be taken to reduce the moisture content of the grains to ensure that the grains meet the storage or purchase conditions. Currently, when local high-moisture grains are found in the granary storage warehouse, it is necessary for the handling workers to carry them out of the warehouse in bags, dry them to a safe moisture content, and then carry them back into the warehouse in bags by the handling workers. This work has a large labor intensity. If it happens to be rainy weather, it can only be spread out in the warehouse, and grain mildew will occur due to the inability to dry it in time. On the other hand, for high-moisture grains after threshing by farmers and large grain growers, if they encounter continuous rainy weather, due to the lack of drying facilities and sufficient space for spreading, economic losses will be caused. In addition, the grain sales vehicles in the granary have to return the vehicles because the grain moisture is slightly higher than the purchase standard, and then unload the grains for drying, load the grains for sale, which not only wastes a lot of time but also increases the costs of unloading, drying, and loading. Therefore, developing a device that can be used for dehumidifying local high-moisture grains in the granary warehouse, can also be used for dehumidifying high-moisture grains of farmers and large grain growers, and can also be used for treating grains with slightly higher moisture content in grain sales vehicles has strong practical significance for reducing post-harvest losses of grains, reducing labor intensity, and improving economic benefits. Utility Model Content

[0003] In view of the above situation, to overcome the deficiencies of the prior art, the purpose of the present utility model is to provide a multi-purpose high-moisture grain dehumidifying device, which can effectively solve the problem of high moisture content in grains.

[0004] The technical solution solved by the present invention is: a multi-purpose high-moisture grain dehumidifying device, including an axial flow fan and a bracket. A grain dehumidifying device integrated as a whole is installed at the air outlet of the axial flow fan. The axial flow fan and the grain dehumidifying device are installed on the bracket. The grain dehumidifying device is composed of a grain storage box and a stirrer. The stirrer is composed of a stirring shaft and stirring blades evenly distributed on the stirring shaft. Both ends of the stirring shaft are installed at the central parts of the cross supports at both ends of the grain storage box through bearings. First ventilation nets and second ventilation nets for preventing grains from flowing out are respectively installed at the openings at both ends of the grain storage box. The upper and lower surfaces of the grain storage box are respectively provided with a grain inlet and a grain outlet. Sealed doors with rubber gaskets are installed on both the grain inlet and the grain outlet. A crank is installed at one end of the stirring shaft extending out of the second ventilation net to form a rotating structure of the stirrer.

[0017] When the present utility model works, it is divided into two working mode situations:

[0018] The first working mode ( Figure 1 ) When the moisture content of the grain in local grain depots, farmers and large grain growers is on the high side (exceeding the standard), the present utility model can be used for moisture reduction. First, start the axial flow fan. By adjusting the forward and reverse directions of the axial flow fan, air is passed through the grain in the grain storage box at high speed in the blowing or suction mode to achieve the purpose of quickly reducing the moisture content of the grain. A stirring device is installed in the cylindrical grain storage box. Both ends of the stirring device rotate through the bearings in the middle of the cross support frame. Periodically rotate the stirring device through the manual crank to make the grain fully mixed, and then evenly reduce the moisture, so that the moisture content of the grain meets the requirements;

[0019] The second working mode ( Figure 2When the water content of medium and small grain piles such as grain depots, large grain growers, and grain-selling vehicles is on the high side (exceeding the standard), the present utility model can be used for dewatering. Fix the circular steel plates of 5 single-pipe joints at the air outlet end of the axial flow fan with screws, vertically or horizontally press 5 grain ventilation pipes into the grain pile with a pipe press, connect one end of 5 annual tendon pipes to 5 single-pipe joints, and the other end to 5 grain ventilation pipes, and then start the axial flow fan for ventilation to let the air pass through the grain pile at high speed, so as to achieve the purpose of quickly reducing the moisture content of the grain and make the moisture content of the grain meet the requirements.

[0020] Through field tests and applications, the above two modes have achieved satisfactory beneficial technical effects. No matter what form of grain has excessive water content, after dewatering with the present utility model, the requirements for storing, transporting, selling, and purchasing grain are all met, ensuring the quality of the grain.

[0021] It can be clearly seen from the above that the present utility model has a novel and unique structure, is easy to produce and manufacture, is convenient to use, has multiple functions and wide applications, can meet the dewatering requirements of grain depots, farmers, large grain growers, or grain trucks with high grain moisture content, and make the moisture content of the grain meet the requirements.
