Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of grain dryer, in particular to a kind of drying machine capable of automatically adjusting discharge gap. BACKGROUND

[0002] In the field of grain processing and storage, the dryer is a commonly used equipment, which is used to reduce the moisture content of grain to prevent mold and prolong storage time. In the drying process of traditional dryer, the grain needs to be evenly discharged through the discharge mechanism to ensure the drying effect of the grain. The discharge mechanism usually includes a discharge port and a discharge wheel, and the grain is discharged through the discharge gap. However, the discharge gap of the traditional equipment is usually fixed and cannot be adjusted according to the discharge speed of the grain and the particle size and type of the grain. Especially when drying different varieties and types of grains, the resistance experienced by the discharge impeller is different. For example, when drying rapeseed, the resistance is small, and when drying long-grain rice, the resistance is large, which can easily cause the discharge impeller to be stuck or even cause the chain driving the rotation of the discharge impeller to break and be damaged, requiring manual intervention for cleaning and maintenance, increasing the maintenance cost and operational complexity.

[0034] Please refer to Figure 1 and Figure 2 The present application provides an automatic adjustment of the clearance of the drying machine of the preferred embodiment, which comprises a drying bin 100, a grain discharge mechanism 200, a grain discharge plate 300 and an elastic member 400.

[0035] The grain discharge mechanism 200 is arranged at the bottom of the drying bin 100, and the bottom of the grain discharge mechanism 200 is formed with a grain discharge port 210, and the grain discharge port 210 is provided with a grain discharge wheel 220. The grain discharge wheel 220 can rotate along its own axis, and the grain discharge wheel 220 is provided with an impeller, and the impeller rotates to drive the material flow. Usually, the grain discharge wheel 220 is connected with a driving motor to realize automatic control.

[0036] The grain discharge plate 300 is located on one side of the grain discharge port 210 and forms a grain discharge gap 301 with the grain discharge wheel 220, and the grain discharge plate 300 is movably installed on the grain discharge mechanism 200 to adjust the grain discharge gap 301 by moving. Figure 5 As shown in the figure, the grain discharge plate 300 can swing back and forth to adjust the grain discharge gap 301.

[0037] The elastic member 400 is connected with the grain discharge plate 300 to apply an elastic force to the grain discharge plate 300 towards the grain discharge wheel 220.

[0038] The utility model provides a kind of drying machine capable of automatically adjusting discharge gap, by the movable installation of discharge plate 300 and the cooperation of elastic member 400, discharge plate 300 can automatically adjust the discharge gap 301 with discharge vane according to the pressure received, to adapt to different kinds and particle size of grain, improve the adaptability and flexibility of drying machine. Since discharge gap 301 can be adaptively automatically adjusted according to the particle size of grain, effectively reduces the risk of discharge wheel 220 being stuck, especially when facing the grain with larger discharge resistance;The discharge gap 301 of automatic adjustment helps to reduce the resistance received by discharge wheel 220, thereby reducing the risk of chain driving discharge wheel to rotate due to excessive stress and breakage damage, in addition, foreign matter, such as stone, iron, etc. can also prevent damage to discharge wheel. Reduce the artificial cleaning and maintenance needs caused by the problems such as discharge wheel being stuck or chain breaking, reduce maintenance cost and operation complexity.

[0039] With reference to Figure 3 And Figure 4 In some embodiments of the utility model, the discharge mechanism 200 includes a grain guide triangular pipe 230 and an inclined plate 240 arranged on both sides of the grain guide triangular pipe 230. The grain guide triangular pipe 230 is arranged with the pointed corner upward. The grain guide triangular pipe 230 includes inclined grain guide plates 231 arranged on both sides. The grain guide plates 231 are arranged close to the bottom of the corresponding inclined plate 240 with a certain interval. The discharge port 210 is formed at the bottom of the corresponding inclined plate 240, so as to guide the material to the discharge port 210. The grain guide triangular pipe 230 is arranged with the pointed corner upward, which can effectively reduce the material residue. The upper ends of the adjacent inclined plates 240 are also connected and fixed together. With the upward pointed corner, the material residue can also be reduced, so that the material can be discharged as completely as possible.

[0040] With reference to Figure 4 And Figure 5In some embodiments of the utility model, the grain discharging wheel 220 is below the bottom of the grain guide plate 231, that is, the grain discharging wheel 220 forms a first projection area on a horizontal plane, the grain guide plate 231 above forms a second projection area on the horizontal plane, and at least half of the area of the first projection area is in the second projection area, that is, at least one side of the grain discharging wheel 220 is vertically shielded by the grain guide plate 231, so that the material flowing down from the grain guide plate 231 will only flow from the other side of the grain discharging wheel 220, and will not flow from both sides of the grain discharging wheel 220, realizing stable control of grain discharging. The bottom of the inclined plate 240 is lower than the bottom of the grain guide plate 231, the grain discharging plate 300 is hinged below the inclined plate 240, the grain discharging plate 300 has an initial state, the grain discharging plate 300 in the initial state abuts against the inclined plate 240, and at this time, the inclined direction of the abutting area of the grain discharging plate 300 and the inclined plate 240 is the same as that of the inclined plate 240, so that the material flowing down from the inclined plate 240 is received along the inclined direction of the inclined plate 240, realizing smooth reception and guidance of the material. Specifically, the elastic member 400 acts on the grain discharging plate 300, so that the grain discharging plate 300 abuts against the inclined plate 240, and the inclined plate 240 is used to limit the position of the grain discharging plate 300 in the initial state. The extension line of the bottom of the grain guide plate 231 intersects with the inclined plate 240, that is, the material flowing from the grain guide plate 231 will first fall on the inclined plate 240, slowing down the flow speed of the material, and avoiding direct impact of the material on the grain discharging plate 300, causing the grain discharging plate 300 to move and affecting the grain discharging gap. By shielding one side of the grain discharging wheel 220 with the grain guide plate 231 and setting the positions of the grain guide plate 231 and the inclined plate 240, the material can be slowed down and flow from the gap between the grain discharging plate 300 and the grain discharging wheel 220, realizing accurate guidance and slow speed of the material, and facilitating control of the grain discharging speed by the grain discharging wheel 220.
