AI Technical Summary
In existing grain dryers, the power unloading and conveying devices are prone to damaging the grain, resulting in high breakage rates and losses.
The gravity unloading mechanism guides the material through the guide surface and baffle on the hopper, using gravity to direct the material to the target area, thus avoiding power transportation.
It effectively reduces grain breakage and loss, and avoids the damage caused by traditional power unloading and conveying.

Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of grain dryers, and specifically relates to a mobile dryer with a gravity unloading mechanism. Background Technology
[0002] Mobile grain dryers generally include a drying system, a hopper system, and a hoisting and circulation system. The most important component in the hoisting and circulation system is the elevator, which is typically an auger elevator or a bucket elevator. Currently, a powered unloading conveyor is usually installed at the discharge end of the elevator. This device transports the material poured out of the hopper to the hopper. The powered unloading conveyor is generally a conveyor belt with a motor. This structure has a drawback: transporting material via a conveyor belt can easily damage the material, especially in grain dryers, resulting in a relatively high grain breakage rate and excessive grain loss and damage. Utility Model Content
[0003] This invention provides a mobile dryer with a gravity unloading mechanism, which can solve the problems pointed out in the background art.
[0004] A mobile dryer with a gravity unloading mechanism includes a bucket elevator, which includes an elevator shell, a conveyor belt, and a plurality of buckets distributed on the conveyor belt. The buckets are connected to the conveyor belt and have guide surfaces. The guide surfaces are used to receive materials poured out from adjacent buckets above and to provide guidance to a target area. Baffles are provided on both sides of the guide surfaces to limit and guide them.
[0005] Preferably, the guide surface is an inclined surface disposed on the lower side of the hopper, and the upper side of the hopper has an inclined discharge port.
[0006] Preferably, the angle between the inclined surface where the guide surface is located and the inclined surface where the inclined discharge port is located is between 40 and 70 degrees.
[0007] Preferably, the angle between the inclined plane where the guide surface is located and the inclined plane where the inclined discharge port is located is between 45 and 65 degrees, the angle between the inclined plane where the guide surface is located and the horizontal plane is between 25 and 35 degrees, and the angle between the inclined plane where the inclined discharge port is located and the horizontal plane is between 20 and 30 degrees.
[0008] Preferably, the discharge port of the elevator casing is provided with a discharge guide pipe, and the guide surface is used to guide the material to the inlet end of the discharge guide pipe.
[0009] Beneficial effects: This utility model provides a mobile dryer with a gravity unloading mechanism, which changes the traditional power unloading and conveying of grain to gravity self-unloading. Under the action of gravity, the grain is guided to the target area by the guide surface on the hopper and the baffle, which will basically not cause any damage to the grain and will basically not cause any breakage.

[0017] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.
[0018] Example 1:
[0019] like Figure 1-5As shown in the figure, the present invention provides a mobile dryer with a gravity unloading mechanism, including a bucket elevator 1. The bucket elevator 1 includes an elevator shell 11, a conveyor belt 12, and a plurality of buckets 13 distributed on the conveyor belt 12. The buckets 13 can be fixed to the conveyor belt 12 by bolts. The buckets 13 are connected to the conveyor belt 12. The buckets 13 have guide surfaces 131, which are used to receive the material poured out by the adjacent buckets 13 above and to provide guidance. The guide surfaces 131 guide the material to the target area. Baffles 132 are provided on both sides of the guide surfaces 131 to limit and guide the material. The plurality of buckets 13 are closely arranged without affecting their respective overturning and unloading, so that the guide surfaces 131 can better receive and guide the material. The discharge port of the elevator shell 11 is provided with a discharge guide pipe 14, and the guide surfaces 131 are used to guide the material to the feed end of the discharge guide pipe 14.
[0020] Specifically, the guide surface 131 is an inclined surface located on the lower side of the hopper 13, and the upper side of the hopper 13 has an inclined discharge port 133. The angle between the inclined surface where the guide surface 131 is located and the inclined surface where the inclined discharge port 133 is located is between 40 and 70 degrees.
[0021] In some embodiments, the angle between the inclined surface where the guide surface 131 is located and the inclined surface where the inclined discharge port 133 is located is between 45 and 65 degrees, the angle between the inclined surface where the guide surface 131 is located and the horizontal plane is between 25 and 35 degrees, and the angle between the inclined surface where the inclined discharge port 133 is located and the horizontal plane is between 20 and 30 degrees.
[0022] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
