Abstract
Description
Technical Field
[0001] The invention relates to the technical field of grain dryers, and in particular to a dryer capable of automatically adjusting a grain discharge gap. Background Art
[0002] In the field of grain processing and storage, dryers are commonly used equipment to reduce the moisture content of grains to prevent mildew and extend storage time. During the drying process, traditional dryers need to discharge grains evenly through the grain discharge mechanism to ensure the drying effect of the grain. The grain discharge mechanism usually includes a grain discharge port and a grain discharge wheel, and the grain is discharged through the grain discharge gap. However, the grain discharge gap of traditional equipment is usually fixed and cannot be adjusted according to the grain discharge speed, grain particle size, and type. Especially when drying different varieties and types of grains, the grain discharge impeller is subject to different resistances. For example, when drying rapeseed, the resistance is small, and when drying long-grain rice, the resistance is large, which can easily cause the grain discharge wheel to get stuck, and even cause the chain that drives the grain discharge wheel to rotate to break and damage, requiring manual intervention for cleaning and repair, which increases maintenance costs and operational complexity. Summary of the invention

[0034] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a dryer capable of automatically adjusting a grain discharge gap, comprising a drying bin 100, a grain discharge mechanism 200, a grain discharge plate 300 and an elastic member 400.
[0035] The grain discharging mechanism 200 is arranged at the bottom of the drying bin 100, and a grain discharging port 210 is formed at the bottom of the grain discharging mechanism 200, and a grain discharging wheel 220 is installed at the grain discharging port 210. The grain discharging wheel 220 can rotate along its own axis, and an impeller is arranged on the grain discharging wheel 220, and the rotation of the impeller drives the flow of materials. Usually, the grain discharging wheel 220 is connected to a driving motor for automatic control.
[0036] The grain discharge plate 300 is located at one side of the grain discharge port 210 and forms a grain discharge gap 301 with the grain discharge wheel 220. The grain discharge plate 300 is movably mounted on the grain discharge mechanism 200 to adjust the grain discharge gap 301 through movement. Figure 5 As shown, the grain discharge plate 300 can swing back and forth to adjust the grain discharge gap 301 .
[0037] The elastic member 400 is connected to the grain discharge plate 300 to apply an elastic force to the grain discharge plate 300 to move toward the grain discharge wheel 220 .
[0038] The present invention provides a dryer capable of automatically adjusting the grain discharge gap. Through the movable installation of the grain discharge plate 300 and the cooperation of the elastic member 400, the grain discharge plate 300 can automatically adjust the grain discharge gap 301 with the grain discharge impeller according to the pressure, so as to adapt to grains of different types and particle sizes, thereby improving the adaptability and flexibility of the dryer. Since the grain discharge gap 301 can be adaptively and automatically adjusted according to the particle size of the grain, the risk of the grain discharge wheel 220 getting stuck is effectively reduced, especially when facing grains with large grain discharge resistance; the automatically adjusted grain discharge gap 301 helps to reduce the resistance of the grain discharge wheel 220, thereby reducing the risk of the chain driving the grain discharge wheel to rotate breaking and being damaged due to excessive force, and can also prevent foreign objects such as stones and iron from damaging the grain discharge wheel. The need for manual cleaning and maintenance caused by problems such as the grain discharge wheel getting stuck or the chain breaking is reduced, and the maintenance cost and operation complexity are reduced.
[0039] Reference Figure 3 and Figure 4 In some embodiments of the present invention, the grain discharge mechanism 200 includes a grain guide triangular tube 230 and inclined plates 240 arranged on both sides of the grain guide triangular tube 230. The grain guide triangular tube 230 is set with its sharp corners facing upward. The grain guide triangular tube 230 includes inclined grain guide plates 231 arranged on both sides. The grain guide plates 231 are close to the bottom of the inclined plates 240 on the corresponding side and are arranged at intervals. The grain discharge port 210 is formed at the bottom of the grain guide plates 231 and the corresponding inclined plates 240, so as to guide the material to the grain discharge port 210. The grain guide triangular tube 230 is set with its sharp corners facing upward, which can effectively reduce material residue. The upper ends of adjacent inclined plates 240 are also connected and fixed together with their sharp corners facing upward, which can also reduce material residue and make the material discharged as cleanly as possible.
[0040] Reference Figure 4 and Figure 5In some embodiments of the present invention, the grain discharge wheel 220 is located below the bottom of the grain guide plate 231, that is, the grain discharge wheel 220 forms a first projection area on a horizontal plane, and the grain guide plate 231 above forms a second projection area on the horizontal plane. At least half of the area of the first projection area is within the second projection area, that is, at least one side of the grain discharge wheel 220 is vertically blocked by the grain guide plate 231, so that after the material flows down from the grain guide plate 231, it will only flow from the other side of the grain discharge wheel 220, and will not flow from both sides of the grain discharge wheel 220, thereby achieving stable control of grain discharge. The bottom of the inclined plate 240 is lower than the bottom of the grain guide plate 231, and the grain discharge plate 300 is hinged below the inclined plate 240. The grain discharge plate 300 has an initial state. The grain discharge plate 300 in the initial state abuts against the inclined plate 240, and at this time, the inclination direction of the abutment area of the grain discharge 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 inclination direction of the inclined plate 240, and the material is smoothly received and guided. Specifically, the elastic member 400 acts on the grain discharge plate 300, so that the grain discharge plate 300 abuts against the inclined plate 240, and the inclined plate 240 is used to realize the position limit of the initial state of the grain discharge plate 300. 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 also preventing the material from directly impacting the grain discharge plate 300, causing the grain discharge plate 300 to move and affect the grain discharge gap. By using the grain guide plate 231 to block one side of the grain discharge wheel 220 and setting the positions of the grain guide plate 231 and the inclined plate 240, the material can be decelerated to a certain extent and flow through the gap between the grain discharge plate 300 and the grain discharge wheel 220, thereby achieving precise guidance and deceleration of the material and facilitating the grain discharge wheel 220 to control the grain discharge speed.
[0041] Reference Figure 4 and Figure 5 In some embodiments of the present invention, the grain discharge plate 300 includes an inclined section 310, a flat section 320 and a raised section 330 connected in sequence; the end of the inclined section 310 away from the hinge is connected to the flat section 320; in the initial state, the inclined section 310 is against the inclined plate 240 and extends downwardly in the direction of the grain discharge wheel 220 to guide the material to the action area of the grain discharge wheel 220, the flat section 320 is located below the grain discharge wheel 220, and the raised section 330 is raised upward at the end of the flat section 320. The raised section 330 can prevent the material from falling from the end of the flat section 320 when no discharge is required, especially when loading grain.
[0042] Reference Figure 4 and Figure 5In a further embodiment of the present invention, the grain discharge mechanism 200 includes a grain discharge frame 250, and the grain guide triangle tube 230 and the inclined plate 240 are fixed in the grain discharge frame 250. A connecting vertical plate 340 is provided at the bottom of the grain discharge plate 300, and the connecting vertical plate 340 is hinged to the grain discharge frame 250 through a hinge shaft, and the connecting vertical plate 340 facilitates the hinge connection of the grain discharge plate 300.
[0043] Reference Figure 4 and Figure 5 In a further embodiment of the present invention, the elastic member 400 is a tension spring, a hook 410 is provided at the end of the tension spring, and the connecting vertical plate 340 is provided with a first hook hole 341 for hooking the hook 410. It can be understood that in order to reduce the material falling on the tension spring, the tension spring and the connecting vertical plate 340 are arranged at both ends of the grain discharge plate 300. The connecting vertical plate 340 is conveniently provided with a hole for hooking the tension spring, and the tension spring is used to apply a stable elastic force to the grain discharge plate 300, so that it can adjust the grain discharge gap according to the pressure it receives.
[0044] Reference Figure 4 and Figure 5 In a further embodiment of the present invention, a triangular rib plate 232 is provided inside the grain guiding triangular tube 230, and both side edges of the triangular rib plate 232 are fitted with the inner side of the grain guiding plate 231, thereby improving the load bearing capacity of the grain guiding plate 231 and reducing deformation.
[0045] Reference Figure 4 and Figure 5 In a further embodiment of the present invention, a connecting strip 233 is provided at the bottom of the triangular rib plate 232, and two second hook holes 234 are provided at the bottom of the connecting strip 233 for hooking the hooks 410 on the tension springs on both sides, thereby providing a convenient hooking position for the hooks 410 of the tension spring, so that the tension spring can avoid the grain discharge wheel 220 and provide elastic tension to the grain discharge plate 300.
[0046] Reference Figure 3 In a further embodiment of the present invention, a plurality of grain guiding triangle tubes 230 and inclined plates 240 are provided and arranged in a horizontal direction to achieve multi-position discharging.
[0047] Reference Figure 3 In a further embodiment of the present invention, the dryer further comprises a material receiving and conveying mechanism 500 and an elevator 600. The material receiving and conveying mechanism 500 is located below the grain discharging mechanism 200 and is used to receive the material discharged by the grain discharging mechanism 200 and convey the material to the elevator 600. The elevator 600 is used to lift the material and convey it to the drying bin 100, thereby realizing cyclic drying. Figure 1 and Figure 2 As shown, the dryer is also provided with a hot air furnace 700 to supply heat to the drying chamber.
