[0002] With the development of science and technology and the improvement of people's living standards, the animal husbandry industry is also gradually developing, and there are more and more large-scale livestock farms. As an important feed for animal husbandry, forage grass needs to remove its own moisture before it can be stored after maturity and harvesting. Traditionally, forage grass is mostly removed from its own moisture by natural drying. Due to the size of the site and weather reasons, the forage grass sometimes does not have time to dry. Therefore, forage grass drying devices came into being. For example, the Chinese utility model patent with authorization announcement number CN214537129U discloses a forage grass drying device. Although it can realize the drying of bales of forage grass, because the forage grass is exposed to the outside, a large amount of heat will be lost to the outside during drying, which not only causes heat waste, but also affects the drying efficiency of the forage grass.

DETAILED DESCRIPTION

[0018] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0019] Embodiment 1:

[0020] like Figures 1 to 4As shown, the square bale hot air drying device described in the utility model includes a bottom plate 1, the left and right ends of the bottom plate 1 are fixedly connected with side plates 3, the side plates 3 are provided with dehumidification ports 16, a sealing frame 10 is fixedly connected between the tops of the two side plates 3, a front baffle 6 and a rear baffle 15 are respectively connected between the front ends and the rear ends of the two side plates 3, a top plate 12 is fixedly connected between the tops of the front baffle 6 and the rear baffle 15, the top plate 12 is connected to the bottom of the bottom plate 1 via a lifting drive assembly, a bellows 11 is fixedly connected to the bottom of the top plate 12, a plurality of wind needles 13 are connected to the bottom of the bellows 11, a plurality of exhaust holes 14 are provided on the side walls of each wind needle 13, and an air inlet 9 penetrating the top plate 12 is connected to the top of the bellows 11.

[0021] When in use, the air inlet 9 is connected to the hot air supply pipeline. At the beginning, the top plate 12 is located at the uppermost position. At this time, the front baffle 6 and the rear baffle 15 will not block the opening between the two side plates 3. Therefore, the square bale of hay to be dried can be smoothly placed between the two side plates 3. Then the lifting drive assembly is activated to drive the top plate 12 to move downward, thereby driving the bellows 11 and the wind needle 13 to move downward, so that the wind needle 13 is inserted into the square bale of hay. When the top plate 12 moves to the lowermost position, the bottom of the top plate 12 is in contact with the sealing frame 10, and the bottom of the front baffle 6 and the rear baffle 15 are in contact with the bottom plate 1, thereby forming a sealed working space for the wind needle 13. Then the hot air is supplied, and the hot air enters the bellows 11 through the air inlet 9, and is then discharged through the exhaust holes 14 on each wind needle 13, drying the square bale of hay from the inside to the outside, and the moisture generated by the drying operation is discharged through the dehumidification port 16.

[0022] The hot air drying device for square bales of hay described in the utility model can enclose a closed drying operation space with the bottom plate 1, the two side plates 3, the sealing frame 10, the top plate 12, the front baffle plate 6 and the rear baffle plate 15 during the drying operation of the hay, thereby effectively preventing a large amount of heat loss during the drying operation, which not only effectively prevents heat waste, but also greatly improves the drying efficiency of the hay.

[0027] Furthermore, a row of rollers 5 are rotatably connected between the lower ends of the two side plates 3, and the wind needles 13 are arranged in rows, and each row of wind needles 13 corresponds to the gap between two adjacent rollers 5. The arrangement of the rollers 5 can make the placement and removal of the hay more labor-saving, and can ensure that the wind needles 13 penetrate the square bale of hay, thereby ensuring the drying effect of the hay;

[0028] Furthermore, the top of the bottom plate 1, the inner sides of the two side plates 3, the bottom of the top plate 12, the rear side of the front baffle 6 and the front side of the rear baffle 15 are all provided with a heat insulation layer, which can effectively prevent the heat loss in the drying operation space, and further improve the drying effect of the forage;
