Description

Technical Field

[0001] This utility model relates to a drying device for grain storage, belonging to the field of grain technology. Background Technology

[0002] Grains refer to the general term for various plant seeds used in cooking, and can also be broadly referred to as "cereals". Grain crops are rich in nutrients, mainly protein, vitamins, dietary fiber, fat, starch, etc. The food concept of the Food and Agriculture Organization of the United Nations refers to cereals, including wheat, beans, whole grains and rice, etc., which are one of the essential foods in people's lives. When storing grains, drying equipment is required.

[0003] Chinese Patent Publication No. (CN 215373404 U) discloses a grain storage drying device, belonging to the technical field of grain storage equipment. It includes a drying box and is equipped with a conveying pipe and a feeding pipe, so that the grain repeatedly enters from the inside of the collection hopper into the inside of the conveying pipe, and then enters the inside of the collection hopper again through the feeding pipe and the guide plate. This allows the grain to repeatedly pass between the drying plates, which facilitates repeated drying of the grain. Since the grain falls freely from the guide plate, the grain is heated evenly between the drying plates, which improves the uniformity of drying and the drying effect. After drying, the servo motor is turned on in reverse, so that the grain moves in the opposite direction inside the conveying pipe and is discharged from the discharge hopper, which is convenient for unloading, easy to use, and easy to operate. The above-mentioned device mainly relies on the combination of heated drying plates and fans to dry grains. However, in actual use, the drying plates generate a lot of heat during operation. This heat will directly act on the fan, which may damage the drive components in the fan. As a result, the overall stability of the equipment when drying grains is poor, making it inconvenient for operators to use.

[0004] Therefore, a grain drying device is proposed. Utility Model Content

[0020] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] Example 1 Figure 1-5 As shown, this utility model embodiment provides a grain drying device for storage, comprising: Drying assembly 1 includes a drying chamber 101. A feed inlet 102 is fixedly installed on the rear side of the top of the drying chamber 101. A discharge port 103 is fixedly installed on the bottom of the drying chamber 101. A cover plate 104 is provided at the bottom of the discharge port 103. A heating chamber 105 is opened on the inner surface of the drying chamber 101. An electric heating wire 106 is fixedly installed in the inner cavity of the heating chamber 105. The material equalization component 2 includes a drive motor 201 and a box body 203. The drive motor 201 is fixedly installed on the top of the drying oven 101. A first connecting rod 202 is fixedly connected to the output end of the drive motor 201. A first stirring rod 208 is fixedly installed on the surface of the first connecting rod 202. The box body 203 is fixedly installed in the inner cavity of the drying oven 101. Second connecting rods 205 are movably connected to both sides of the box body 203. Second stirring rods 209 are fixedly installed on the surface of both second connecting rods 205. A third connecting rod 210 is movably connected to the bottom of the box body 203. Spiral blades 212 are fixedly installed on the bottom surface of the third connecting rod 210. A third stirring rod 211 is fixedly installed on the surface of the third connecting rod 210. A drive bevel gear 204 is movably connected to the top of the inner cavity of the box body 203. A linkage bevel gear 206 is movably connected to the right side of the inner cavity of box 203, and a transmission bevel gear 207 is movably connected to the bottom of the inner cavity of box 203. The other ends of the two second connecting rods 205 are fixedly connected to the left and right sides of the linkage bevel gear 206. The other end of the first connecting rod 202 is fixedly installed on the top of the driving bevel gear 204. The top of the third connecting rod 210 is fixedly installed on the bottom of the transmission bevel gear 207. The surface of the linkage bevel gear 206 meshes with the surfaces of the driving bevel gear 204 and the transmission bevel gear 207. The dimensions of the two first stirring rods 208 and the two third stirring rods 211 are consistent with each other. The rotation directions of the first stirring rod 208 and the third stirring rod 211 are opposite. The spiral blade 212 and the discharge port 103 are in the same vertical direction. The bottom of the spiral blade 212 extends into the inner cavity of the discharge port 103.

[0023] By setting up the material equalization component 2, the output of the drive motor 201 causes the first connecting rod 202 to drive the first stirring rod 208 to rotate. The active bevel gear 204, the linkage bevel gear 206, and the transmission bevel gear 207 cooperate with each other to make the second stirring rod 209 and the third stirring rod 211 also rotate. The first stirring rod 208 and the third stirring rod 211 rotate in opposite directions at a synchronous frequency, while the second stirring rod 209 rotates laterally. This achieves the stirring and turning of the grain in the inner cavity of the drying box 101, thereby expanding the contact area between heat and grain in the drying box 101, ensuring the uniformity and stability of grain drying, and making it convenient for operators to use.

[0024] Example 2 Figure 1-6As shown, in one embodiment, the bottom of the cover plate 104 is threaded with mounting bolts 107, the top of the mounting bolts 107 is threaded to the inner surface of the discharge port 103, a humidity sensor 109 is fixedly installed on the left side of the top of the drying chamber 101, the detection end of the humidity sensor 109 extends into the inner cavity of the drying chamber 101, a temperature sensor 108 is fixedly installed on the right side of the top of the drying chamber 101, the detection end of the temperature sensor 108 extends into the inner cavity of the drying chamber 101, and a base plate 110 is fixedly installed at the bottom of the drying chamber 101, the top of the base plate 110 is threaded with anchor bolts 111.

[0025] By installing mounting bolts 107, the cover plate 104 can be disassembled and assembled, facilitating material discharge via the spiral blades 212. By installing humidity sensor 109, the humidity inside the drying chamber 101 can be detected, allowing operators to understand the moisture level of the grain. By installing temperature sensor 108, the temperature inside the drying chamber 101 can be detected, allowing operators to understand the heating status inside the drying chamber 101. By installing anchor bolts 111, the overall equipment can be stabilized, preventing shaking caused by accidental collisions.

[0026] In operation, this invention works as follows: First, grain is poured into the inner cavity of the drying chamber 101 through the feed inlet 102. Then, the temperature inside the drying chamber 101 is raised by the heating wire 106. Subsequently, the output of the drive motor 201 drives the first connecting rod 202, the first stirring rod 208, and the driving bevel gear 204 to rotate. When the driving bevel gear 204 rotates, it drives the linkage bevel gear 206 and the second connecting rod 205 to rotate. The second connecting rod 205 synchronously drives the second stirring rod 209 to rotate and stir. When the linkage bevel gear 206 rotates, it synchronously drives the transmission bevel gear. Rotation of the transmission bevel gear 207 drives the third connecting rod 210, the third stirring rod 211, and the spiral blade 212 to rotate. When the spiral blade 212 rotates, it causes the grain to tumble from bottom to top. Meanwhile, the second stirring rod 209, the third stirring rod 211, and the first stirring rod 208 tumble and stir the grain in the inner cavity of the drying chamber 101, so that the grain in different areas is evenly contacted with the hot air. After drying is completed, the cover plate 104 is disassembled, and then the drive motor 201 outputs in reverse, causing the spiral blade 212 to rotate in reverse. The spiral blade 212 conveys and discharges the dried grain, completing the overall drying of the grain.

Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
