Description
Technical Field
[0001] The utility model relates to the field of grain distribution equipment, in particular to an automatic vending machine capable of storing rice for a long time. Background Art
[0002] Rice is a finished product made from rice grains after cleaning, husking, milling, and finishing. Rice contains about 75% carbohydrates, 7%-8% protein, 1.3%-1.8% fat, and is rich in B vitamins. The carbohydrates in rice are mainly starch, and the protein it contains is mainly glutenin, followed by rice gelatin and globulin. The biological value of its protein and the composition ratio of amino acids are higher than those of cereal crops such as wheat, barley, millet, and corn. The digestibility is 66.8%-83.1%, which is also a higher one among cereal proteins. Therefore, edible rice has a higher nutritional value.
[0003] Rice, as a kind of rice, flour, grain and oil, is usually sold in supermarkets or vegetable markets. When a user finds that there is not enough rice at home when cooking, and there is no supermarket or vegetable market near the user's residence, the time consumed by the user to buy rice will increase; vending machines have the characteristics of small footprint and can be deployed in most public spaces.

The sealing cover is covered on the feed port. When the first silo 31 is filled with bulk rice, the bulk rice is put into the first silo 31 through the feed port by turning over the sealing cover, and then the sealing cover is covered to prevent outside air from entering the first silo 31, thereby improving the sealing and fresh-keeping effect of the first silo 31.
[0032] Furthermore, the bottom of the first barn 31 is connected to the top of the second barn 32, and a depression is provided on the top of the first barn 31.

The multiple second air ducts 421 arranged in a rectangular array can allow the interior of the bulk rice to be injected with hot air, which can make the bulk rice more evenly evaporate the internal moisture by the hot air, thereby achieving the effects of mildew prevention, insect prevention, freshness preservation, and quality improvement; the bottom of the diverter box 42 is connected to the third air duct 422.
[0034] The exhaust mechanism 5 includes an exhaust device 51 and two exhaust pipes 52. The exhaust device 51 is fixedly connected to the inner wall of the first cabinet 2, and the exhaust device 51 passes through the first cabinet 2; one end of the exhaust pipe 52 is connected to the exhaust device 51, and the other ends of the two exhaust pipes 52 are respectively connected to the two sides of the first barn 31; when the drying mechanism 4 injects hot air into the first barn 31, the evaporated water vapor is sucked away by the exhaust device 51 through the exhaust pipe 52, so that the first barn 31 remains dry.
[0035] A chamber 321 is provided at the bottom of the second silo 32, and a valve assembly 33 is provided in the second silo 32. The valve assembly 33 is placed in the chamber 321, and one side of the chamber 321 is connected to the second silo 32. A discharge port 322 is provided on the inner wall of the other side of the chamber 321. The valve assembly 33 includes a central axis 332 and a first motor 331. The two ends of the central axis 332 are rotatably connected to the top and the bottom of the chamber 321, respectively. The first motor 331 is fixedly connected to the bottom of the second silo 32, and the output shaft of the first motor 331 penetrates the chamber 321 and is fixedly connected to the central axis 332. Four blades 333 are fixedly connected to the outer side of the central axis 332, and the angle formed between two adjacent blades 333 is 90°.
[0036] Furthermore, a cavity is formed between two adjacent blades 333, and four cavities are formed by four blades 333, and the outer sides of the blades 333 are in contact with the inner wall of the chamber 321; when the middle shaft 332 rotates and drives one of the blades 333 to be located above the discharge port 322, the cavities on one side of one of the blades 333 are all connected to the discharge port 322 and the second barn 32, and the cavities on the other side of one of the blades 333 are only connected to the discharge port 322; when the discharge port 322 is located between two adjacent blades 333, the cavity close to the discharge port 322 is only connected to the discharge port 322;

[0038] When the drying mechanism 4 is injecting hot air into the second barn 32, the first motor 331 drives the central axis 332 to rotate, so that one of the blades 333 is located above the discharge port 322, and the humid air in the second barn 32 can be pushed out of the second barn 32 from the cavity on one side of the blades 333 by the hot air, thereby reducing the humidity in the second barn 32; when the second barn 32 needs to release bulk rice, the first motor 331 drives the central axis 332 to rotate, so that the four cavities are connected with the second barn 32 in turn, so that the bulk rice in the second barn 32 flows into the cavity; when the cavity moves to above the discharge port 322, the bulk rice in the cavity is discharged from the discharge port 322. At this time, the cavity is not connected with the second barn 32, thereby reducing the external air entering the second barn 32, and the four cavities move in turn close to the discharge port 322 to release the internal bulk rice.

The bagged rice on the shelf is pushed away by the pushing mechanism, allowing the bagged rice to fall into the second commodity outlet to complete the sale.
[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
