Description

Technical Field

[0001] The utility model belongs to the technical field of drying equipment, and particularly relates to a grain drying device. Background Art

[0002] In agricultural production, grain drying is a crucial process. After harvesting, grains contain a high amount of moisture. If they are not dried in time, they will easily breed mold and pests, resulting in a decline in grain quality and even serious losses. Traditional drying methods rely on natural air drying or wind drying; although the cost is low, the efficiency is low and it is easily restricted by climatic conditions. With the development of agricultural modernization, improving drying efficiency, reducing energy consumption, and ensuring grain quality have become the main goals of grain drying technology research and development. Therefore, designing an efficient grain drying device is of great significance to ensuring food security and improving agricultural production levels.

[0003] For example, a grain drying device with patent application number CN202320727518.X discloses "comprising a device housing, a dispersing member is arranged at the upper end of the device housing, a feed inlet is arranged above the dispersing member, a mounting frame is installed inside the device housing, a driving motor is installed inside the mounting frame, an output shaft of the driving motor is connected to a transmission shaft, two inclined plates are installed on the outer wall of the transmission shaft, a guide plate is fixed to the inner wall of the device housing, a collecting chamber is arranged below the guide plate, and a discharge pipe is arranged on the left side of the collecting chamber. The utility model provides a dispersing member with a feed inlet. The grains to be dried can be poured into the device shell through the material inlet, which is easy to use; the drive motor is started to drive the transmission shaft to rotate, thereby driving the inclined plate to rotate, so that the grains can be scattered, which can effectively reduce the accumulation of grains and improve the drying effect. Although the above structure can achieve the purpose of drying grains, it cannot guarantee the drying effect of most grains due to the short drying stroke and the short drying time. Moreover, when the above equipment is unloading, some grains will directly fall to the bottom of the box, and the drying process is extremely short. When the unloading material is too large, it is easy to cause the drying effect to fail.

[0004] In order to solve the above problems, we provide a grain drying device which can continuously dry grains and ensure that the drying time of most grains is close to ensure that the drying effect of most grains is the same and avoid grains being blocked in the drying cylinder. Utility Model Content

[0005] The utility model aims to overcome the deficiencies in the prior art and provide a grain drying device.

[0006] The purpose of the utility model is achieved as follows: a grain drying device comprises a box body, a hot air blower is arranged in the box body, a drying cylinder is arranged above the box body, a rotatable spiral discharge plate is arranged in the drying cylinder, a cover plate is arranged at the upper end of the drying cylinder, a discharge hopper and an exhaust pipe are arranged on the cover plate, and a discharge pipe is arranged on the side of the lower end of the drying cylinder.

[0007] Furthermore, the hot air blower supplies hot air to the lower part of the drying cylinder.

[0008] Furthermore, an air inlet pipe is fixedly arranged above the box body, the air inlet pipe is connected to the output end of the hot air blower, and the air inlet pipe is connected to the drying cylinder.

[0009] Furthermore, a conical head is fixedly provided at the upper end of the air intake pipe, and a plurality of ventilation holes 1 are evenly opened on the conical head, and the ventilation holes 1 are connected with the air intake pipe.

[0010] Furthermore, ventilation holes 2 are evenly opened on the spiral blanking plate 1.

[0011] Furthermore, a second spiral feed plate is fixedly provided on the inner side of the drying cylinder.

[0012] Furthermore, ventilation holes three are evenly opened on the spiral blanking plate two.

[0013] When the utility model is used, the grains are placed in the lower hopper, and the grains enter the drying cylinder through the lower hopper, and the grains fall onto the spiral lower plate 1 and the spiral lower plate 2; the spiral structure of the spiral lower plate 1 and the spiral lower plate 2 can increase the falling stroke of the grains, which is conducive to the full drying of the grains. The grains slide downward along the spiral lower plate 1 and the spiral lower plate 2 under the action of their own gravity; at the same time, the hot air blower is started to supply hot air to the drying cylinder through the air inlet pipe to heat and dry the grains; the exhaust fan can also be turned on as needed to extract the hot air in the drying cylinder, and the mutual cooperation between the exhaust fan and the hot air blower can ensure the smooth flow of hot air in the drying cylinder. Since the spiral lower plate 1 and the spiral lower plate 2 are arranged in the drying cylinder, and ventilation holes are opened on each top, the hot air moves upward along the spiral lower plate, and at the same time, part of the gas passes through the ventilation holes and moves upward through the spiral lower plate to achieve the drying of the grains.

[0014] The dried grains fall onto the conical head below, and the grains fall downward along the conical head; the dried grains are discharged through the discharge pipe.

[0015] In order to solve the problem that grains are piled up between the spiral feeding plates and cannot be discharged during the drying process, a spiral feeding plate 1 and a spiral feeding plate 2 are provided which can rotate relatively. That is, the rotating motor drives the rotating rod to rotate, thereby driving the spiral feeding plate 1 to rotate, so that the grains located on the spiral feeding plate 1 and the spiral feeding plate 2 are staggered with each other. At the same time, the rotation of the spiral feeding plate 1 can effectively drive the grains above it to fall, so as to solve the problem of material blockage.

[0016] Beneficial effects: The present application can realize the drying of grains, and the technical solution of continuously feeding and drying grains can increase the drying efficiency; a spiral feeding plate 1 and a spiral feeding plate 2 which can rotate relatively are provided, and a rotating motor drives a rotating rod to rotate, thereby driving the spiral feeding plate 1 to rotate, so that the grains located on the spiral feeding plate 1 and the spiral feeding plate 2 are staggered with each other, and at the same time, the rotation of the spiral feeding plate 1 can effectively drive the grains above it to fall, so as to solve the problem of material blockage.

[0022] The hot air blower 2 supplies hot air to the lower part of the drying cylinder 5. An air inlet pipe 3 is fixedly arranged above the box body 1, and the air inlet pipe 3 is connected to the output end of the hot air blower 2, and the air inlet pipe 3 is connected to the drying cylinder 5. A cone head 10 is fixedly arranged at the upper end of the air inlet pipe 3, and a plurality of ventilation holes 1 are evenly opened on the cone head 10, and the ventilation holes 1 are connected to the air inlet pipe 3.

[0023] Ventilation holes 2 are evenly arranged on the spiral unloading plate 12. A spiral unloading plate 2 11 is fixedly arranged on the inner side of the drying cylinder 5. Ventilation holes 3 are evenly arranged on the spiral unloading plate 2 11. A rotating rod 13 is fixedly connected to the inner side of the spiral unloading plate 12, and the rotating rod 13 drives the spiral unloading plate 12 to rotate. The upper end of the rotating rod 13 rotatably penetrates the cover plate 9, and a rotating motor 7 is fixedly arranged on the cover plate 9, and the rotating motor 7 drives the rotating rod 13 to rotate. The lower end of the rotating rod 13 is rotatably connected to the conical head 10. There is a clearance fit between the spiral unloading plate 12 and the spiral unloading plate 2 11 to prevent a large amount of grain from falling directly between the two and affecting the drying effect.

[0024] When the utility model is used, the grains are placed in the lower hopper 8, and the grains enter the drying cylinder 5 through the lower hopper 8, and the grains fall onto the spiral lowering plate 12 and the spiral lowering plate 2 11; the spiral structure of the spiral lowering plate 12 and the spiral lowering plate 2 11 can increase the falling stroke of the grains, which is conducive to the full drying of the grains.
