As shown in fig. 5, the side wall of the storage bin 2 is formed by assembling multiple sections of coamings 21 and 22, one side of each section of coaming is provided with a first convex edge 211 protruding outwards, the other side of each section of coaming is provided with a first concave edge 221 matched with the first convex edge 211, the first concave edge 221 is concavely formed into a space for accommodating the first convex edge 211 in a matched and spliced manner, and when the first convex edge 211 is matched and spliced with the first concave edge 221, a through mounting hole is formed in the first convex edge 211 and the first concave edge 221, and two ends of the same section of coamings 21 or two adjacent sections of coamings 21 and 22 can be spliced together by inserting a bolt 23 into the mounting hole. According to the perimeter of the required bin, the corresponding coaming is selected to be assembled into the side wall of the bin, or coamings with different heights are selected to be assembled, bins with different capacities can be formed by enclosing, the automatic assembly of planting farmers according to the grain storage amount is facilitated, the disassembly and the transportation are facilitated, and the flexibility is improved.

The inside of feed bin 2 and be provided with the infundibulate metal mesh 6 of relative closely knit apart from bottom plate 4 certain distance, form certain air inlet space 7 between metal mesh 6 and the feed bin bottom plate 4, make air inlet space 7 and air intake 42 form and link up. The dense metal net not only ensures that grains in the bin do not leak downwards into the air inlet space 42 from the upper part of the bin, but also enables air in the air inlet space 42 to blow into grains in the bin.

The metal net 6 at the funnel-shaped lowest position in the center of the metal net 6 is fixedly provided with a supporting frame 8, the upper part of the supporting frame 8 is provided with a vent pipe 9, and the wall of the vent pipe 9 is provided with a plurality of vent holes 91. A discharge channel 10 is communicated between the lower part of the support frame 8 and a discharge hole 41 on the bottom plate 4. The support frame 8 is used for supporting and installing the vent pipe 9, and meanwhile, grains pass through the vent pipe and enter the discharging channel 10. When the discharge hole 41 is opened, grains flow to the lowest position along the funnel-shaped metal net 6, enter the discharge channel 10 through the support frame 8, flow out through the discharge hole 41, and realize grain discharge. Meanwhile, wind blown upwards through the metal net 6 passes through the supporting frame 8 and enters the ventilation pipe 9, and is diffused into grains in the central area of the storage bin through the ventilation holes 91, so that the problem that the central area is difficult to air dry to cause mildew is avoided.

The inside of the storage bin surrounds the breather pipe 9 and is provided with a plurality of air inlet pipelines 11 communicated with the air inlet space 7, and the air inlet pipelines 11 are also arranged along the inner side of the coaming. A plurality of air dispersing holes 111 are arranged on the wall of the air inlet pipeline 11.

The air inlet 42 can be connected with a common fan, natural wind is blown into the air inlet space, the wind enters the storage bin through the air inlet pipeline, and the wind is dispersed and blown into grains around the air inlet pipeline through the air dispersing holes. All the air inlets are blown upwards and dispersed, and finally discharged through gaps between the side walls of the storage bin and the cone-shaped top cover. The flow of wind drives excessive moisture in the grain, so that the moisture in the grain is reduced, and the grain is prevented from mildew and deterioration. The air inlet can be connected with an electric heating fan to blow hot air into the air inlet space, so that the purpose of controlling and adjusting the grain moisture in the storage bin is achieved when the grain moisture is difficult to continuously reduce through natural air or in special overcast and rainy weather conditions. When the moisture content in the grain is reduced to a certain extent, the moisture content is not different from the humidity in the air, or the moisture content is poor in air drying effect and long in time consumption only by natural wind in overcast and rainy days or foggy days, the moisture content in the grain is difficult to continuously reduce, and the moisture content cannot reach the national library grain purchasing standard moisture content. At this time, the electric heating fan is adopted at the air inlet to blow hot air into the air inlet space, so that the moisture content of grains can be rapidly and continuously reduced, and the grains can be sold according to national library purchasing standards.

The grain air-dries by adopting the mode that natural wind and hot air combine, compares more energy saving with adopting drying equipment, takes into account air-drying efficiency, effect and cost, has avoided the destruction of drying equipment high temperature to the grain nutrient composition that grain dehydration and drying caused moreover, has guaranteed the quality in the grain storage process to the maximum extent.

The end of the air inlet pipe 11 extending upward is a closed end, so that grains are prevented from entering the air inlet pipe 11, and wind entering the air inlet pipe 11 is dispersed into the grains through the air dispersing holes 111.

In the preferred scheme, the height of the air inlet pipeline is always lower than the height of grains stored in the storage bin, so that the air inlet pipeline is always buried in the grains, the air scattered by the air scattering holes is prevented from being wasted, and energy is saved. The height of the air outlet pipe is always higher than the height of grains stored in the storage bin.

The intake pipes 111 are arranged in a honeycomb shape in cross section and distributed around the ventilation pipe. The N air inlet pipelines are in a group, and the top of each air inlet pipeline in each group is connected and communicated through the top pipe to form a closed end. The jacking pipe is a straight jacking pipe or an annular jacking pipe or N straight jacking pipes are connected in a penetrating mode to form a closed loop. The number of N is 2, 3 or more than 3, for example, 2 air inlet pipelines are in a group, and the tops of the 2 air inlet pipelines are connected and communicated by a jacking pipe (shown in figure 2). The top pipe can also be provided with an air vent. The inside air inlet pipeline of air-drying tower is connected and is set to honeycomb, has increased the area of contact of grain and wind, more does benefit to ventilation drying, cooperates the push pipe simultaneously, has further increased air-drying tower structural stability, has guaranteed the stability and the reliability of air-drying tower in-process structure.

When the grains stored in the storage bin are fewer, the grains are easier to air, the air drying effect can be achieved only by air inlet into the grains through the metal mesh, and air does not need to be blown through the air inlet pipeline, so that the lower pipe openings of all or part of the air inlet pipeline can be sealed.

The side wall of the storage bin is provided with a sampling hole 12 through which a grain sample in the storage bin can be taken out for detecting the moisture content.

The honeycomb type movable grain air drying tower provided by the utility model has the advantages of simple structure, good stability, low construction cost, strong practicability and convenience in movement, avoids the limitation of places when farmers store, and is convenient for common planting farmers to use.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, shall cover the scope of the present utility model by equivalent substitution or modification according to the technical scheme of the present utility model and the patent conception thereof.
