[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Please see Figure 1-6This utility model provides a technical solution: a crop drying device, including a light steel composite frame 1, with insulation boards 2 fixedly installed on the outer surface of the light steel composite frame 1, and the insulation boards 2 are closely fitted together and located on the four sides of the light steel composite frame 1. A hopper door 3 is rotatably installed on one side surface of the light steel composite frame 1, and the hopper door 3 is interlocked with the light steel composite frame 1, with the outer surface of the light steel composite frame 1 and the outer surface of the hopper door 3 in contact. A circulating fan 6 is fixedly installed on the outer surface of the light steel composite frame 1, and the circulating fan 6 is located inside the insulation boards 2. An electric air inlet 5 is fixedly installed on the side surface of the insulation boards 2 near the circulating fan 6. A heat exchange mechanism is provided inside the light steel composite frame 1 and the insulation boards 2, which can increase the temperature inside the insulation boards 2 and accelerate the drying speed of the materials placed inside the insulation boards 2.

[0030] The light steel composite frame 1 facilitates assembly and transportation, reducing construction time. The insulation board 2 provides insulation for drying and reduces heat loss. The design of the silo door 3 allows for complete opening and closing, making it easy to push materials into the drying device and convenient to push them out after drying.

[0031] The heat exchange mechanism includes: a heat pump outdoor unit 7, which is fixedly installed on the outer surface of the light steel composite frame 1. The heat pump outdoor unit 7 is located outside the insulation board 2, and an internal heat exchanger 8 is fixedly installed inside the insulation board 2. The internal heat exchanger 8 is connected to the heat pump outdoor unit 7. A dehumidification window 10 is opened on the outer surface of the insulation board 2 near the heat pump outdoor unit 7, and the dehumidification window 10 faces the heat pump outdoor unit 7.

[0032] By starting the outdoor unit 7 of the heat pump, heat is transferred to the heat exchanger 8 inside the heat pump. Air is drawn in from the electric air inlet 5 by the circulating fan 6, and the air is heated by the heat exchanger 8 inside the heat pump. The circulating fan 6 blows the material to dry it, and the intermittent opening of the electric air inlet 5 changes the air pressure, allowing the exhaust window 10 to be opened, thus intermittently expelling moisture from the exhaust window 10 to accelerate the dehydration and drying of the material. The exhausted hot and humid air will pass through the outdoor unit 7, allowing the outdoor unit 7 to absorb the heat of the exhausted air, which facilitates the increase of the workload of the outdoor unit 7, thereby reducing the overall power consumption of the drying device and reducing electricity consumption. It also allows the material to be dried more quickly and prevents the chili peppers from spoiling and becoming contaminated.

[0033] A blowing and circulation mechanism is provided between the light steel composite frame 1 and the insulation board 2. The blowing and circulation mechanism allows the air drawn in by the circulating fan 6 to circulate inside the insulation board 2, drying the material placed inside the insulation board 2. The blowing and circulation mechanism includes: a return air baffle 9, which is fixedly installed in the center of the light steel composite frame 1. A return air inlet 12 is opened on the side surface of the return air baffle 9 near the heat pump outdoor unit 7. The circulating fan 6 is evenly arranged on the outer surface of the insulation board 2. The circulating fan 6 and the heat exchanger 8 inside the heat pump are designed in parallel. The outer surface of the return air baffle 9 is evenly provided with through holes.

[0034] As the circulating fan 6 rotates, it pushes air through the heat exchanger 8 inside the heat pump, allowing the hot air to move along the direction of the return air baffle 9 and pass through the return air inlet 12 and be reheated by the heat exchanger 8 inside the heat pump. This allows the air to circulate inside the insulation board 2 and continuously heat the air, accelerating the drying of the material and increasing the heating speed of the hot air.

[0035] An inspection door 4 is provided on the outer surface of the insulation board 2 at one end near the heat exchanger 8 in the heat pump. Another inspection door 4 is provided on the outer surface of the insulation board 2 between the circulating fan 6 and the heat exchanger 8 in the heat pump. An observation window 11 is provided on the outer surface of the insulation board 2 at one end near the dehumidification window 10. Another observation window 11 is provided on the outer surface of the door 3.

[0036] The interior of the insulation board 2 can be easily accessed through the inspection door 4 to inspect and replace the circulating fan 6 and the heat exchanger 8 in the heat pump. The drying status of the materials placed in the middle and end sections can also be viewed through the observation window 11.

[0037] The light steel composite frame 1 and the insulation board 2 are equipped with a plug-in placement mechanism, which facilitates the placement and removal of materials from the drying device.

[0038] Materials can be conveniently placed using the material rack chassis 13 and universal rollers 14, allowing a large amount of material to be pushed into the drying device at once, and a large amount of material to be taken out at once after drying is completed.

[0039] The insertion and placement mechanism includes: a universal roller 14, a material rack chassis 13 fixedly mounted on the outer surface of the universal roller 14, a wire mesh 15 fixedly mounted on the outer surface of the material rack chassis 13, an insertion leg 16 fixedly mounted on the outer surface of the material rack chassis 13, and the insertion leg 16 is inserted into the insertion leg 16 of another material rack chassis 13.

[0040] The material rack base 13 can be easily connected and combined with each other by the plug-in legs 16, which facilitates transportation and stacking without taking up too much space. During the drying process, hot air can pass through the wire mesh 15, allowing the airflow to pass through quickly and accelerating the drying of the material. When the material rack base 13 and the wire mesh 15 are damaged, they can be easily replaced individually for easy maintenance and to ensure continued use.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
