Description

Technical Field

[0001] The invention belongs to the technical field of grain drying, and in particular relates to a grain drying system. Background Art

[0002] With the rapid development of my country's agriculture and the improvement of planting technology, farmers harvest more and more crops every year. Newly harvested grains must be dried as soon as possible to ensure their good quality, but a large amount of harvest has brought difficulties to farmers.

[0003] At present, the rice drying process of the rice processing industry mostly adopts the traditional drying machine drying method using fuel oil or biomass as a heat source, which has a great impact on the atmospheric environment, and the rice produced is of poor quality and high cost. The traditional drying method using solar energy as a heat source generally involves manually spreading the grains on an open-air grain field in the morning and collecting them at night, but there are not many areas available for drying. During the busy farming season, farmers often fight over drying areas, and some even dry grains on the road, which not only occupies public areas and congests traffic, but also easily causes traffic accidents. In addition, the process of collecting grains is extremely labor-intensive and time-consuming, and there is no guarantee that the grains will be collected cleanly. If a sudden heavy rain occurs during the drying process, manual collection will not be able to recover all the grains, resulting in a large loss of grains in the drying process. These labor-intensive and high-risk links will eventually be converted into costs, which seriously restricts the high-quality development of the high-end silk seedling industry. Summary of the invention

[0004] The purpose of the present invention is to provide a grain drying system which occupies a small site, has a large drying area, is highly efficient, does not require manual spreading and collection, realizes automatic loading and unloading, and effectively ensures the grain quality.

Therefore, the key to implementing a grain drying system provided by an embodiment of the present invention is as follows: first, the drying body 23 adopts a vertical W-shaped structure, and a W-shaped material channel is designed from top to bottom. On the one hand, the space of the drying rack 2 can be fully utilized to increase the drying area of ​​the material and improve the drying efficiency. On the other hand, the material can be automatically spread along the W-shaped material channel under its own gravity, and the purpose of automatic material discharge can be achieved by opening the rotary discharge valve when unloading, without manual spreading and collection, thereby reducing the labor intensity and labor cost of workers. In addition, the drying rack 2 is an overhead drying rack with good ventilation and small site occupation. It will not be affected by ground moisture due to contact with the ground, nor will it adhere to dust and debris on the ground. At the same time, it can also prevent problems such as bird kicking, chicken pecking, and mouse biting. Secondly, through the setting of the feeding device 3, the material output component 32 can be transferred above the feed port 24 of each drying rack 2, so that the material to be dried can be fed into the drying rack 2 in an orderly manner, and automatic feeding can be achieved. Thirdly, by setting the discharging device 4, the material loading component 42 can be transferred under the discharging port 26 of each drying rack 2, so that the materials after drying can be sent out of the drying rack 2 in an orderly manner, realizing automatic discharging.

[0026] Exemplarily, the drying body 23 includes a first plate 231 as the bottom plate of the W-shaped material channel, a second plate 232 as the top plate of the W-shaped material channel, and a W-shaped frame 233 for fixing the first plate 231 and the second plate 232. The first plate 231 and the second plate 232 are arranged in parallel and spaced apart. The first plate 231 is a flat plate, and the second plate 232 is a mesh plate. The flat plate serves as the bottom plate of the W-shaped material channel and is also the backlight surface, which enables the material to slide smoothly under its own gravity. The mesh plate serves as the top plate of the W-shaped material channel and is also the light-facing surface, which facilitates the ventilation of the material during drying. Of course, in other embodiments, the first plate 231 and the second plate 232 can both be mesh plates, and a double mesh plate structure is adopted, which has better air permeability. However, due to the phenomenon of hanging materials in the mesh holes, the material does not slide smoothly. If necessary, a vibrator can be added to assist in material spreading and unloading.

[0027] Exemplarily, the angle of each V-shaped corner of the drying body 23 is 30 degrees to 60 degrees, so as to ensure that the material can be spread and discharged along the W-shaped material channel under the action of its own gravity.

[0028] Exemplarily, the valve is preferably a rotary discharge valve to achieve uniform and continuous discharge.

[0029] Exemplarily, the drying room 1 is preferably a greenhouse glass room, which facilitates direct sunlight into the room.

[0032] Exemplarily, in order to make the system have a high level of automation and to achieve fully automatic control of ambient temperature, ambient humidity, material humidity, material weight, etc., the drying rack 2 is provided with a temperature sensor for detecting the ambient temperature of the drying rack 2, a humidity sensor for detecting the humidity of the drying material and the ambient humidity of the drying rack 2, and a weight sensor for detecting the weight of the drying material; the drying room 1 is provided with a heat pump device 5 (or other heating device arranged on the drying rack) that can supply heat to the drying room 1 and a ventilation device 6 that can ventilate the drying room 1; the grain drying system also includes a central controller, which is electrically connected to the temperature sensor, the humidity sensor, the weight sensor, the loading device 3, the discharging device 4, the heat pump device 5, the ventilation device 6 and the rotary unloading valve, respectively.

[0033] Among them, when the temperature sensor detects that the ambient temperature of the drying rack 2 (i.e., the indoor ambient temperature) is lower than the preset ambient temperature, the central controller controls the heat pump device 5 to start, so that the indoor ambient temperature increases until the indoor ambient temperature stabilizes at the preset ambient temperature. When the humidity sensor detects that the ambient humidity of the drying rack 2 is higher than the preset ambient humidity, the central controller controls the heat pump device 5 and the ventilation device 6 to start, so that the indoor ambient humidity decreases until the indoor ambient humidity stabilizes at the preset ambient humidity. When the humidity sensor detects that the material humidity is lower than or equal to the preset material humidity, the central controller controls the rotary discharge valve and the discharging device 4 to start, and delivers the material that meets the quality standard, otherwise continue to dry. When the weight sensor detects that the material weight is higher than or equal to the preset weight, the central controller controls the feeding device 3 to stop feeding, otherwise continue to feed.
