Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically a grain dryer. Background Technology

[0002] Grain dryers, also known as grain dryers or grain drying machines, are mechanical devices used to remove moisture from grains. They are widely used in agriculture, food processing, and other fields, and play an important role in improving the storage stability of grains, extending their shelf life, and improving their quality.

[0003] According to CN206760631U, an infrared heating grain drying device includes an outer tank with exhaust vents on both sides of the top of the outer tank. An inner cylinder is located inside the outer tank. A hot air blower is installed at the bottom of the inner support ring plate. The outer wall of the inner cylinder has an internal through-hole. An infrared heating device is installed inside the outer tank. This infrared heating grain drying device, through the cooperation of the infrared heating device, the inner cylinder, and the outer metal mesh plate, generates hot air through the side slots on the outer side of the bottom support ring plate. At the junction of the inner cylinder and the outer tank, the moisture from the grain inside the inner cylinder exchanges with the hot air through the inner through-hole. Meanwhile, light is refracted by the bottom refractive plate and the arc refractive plate and then reflected out through the opening, which improves the light irradiation effect. The combination of infrared heating device and hot air blower enhances the drying effect of the grain and meets the needs of production and processing. As can be seen from the above, although this drying equipment can be used well, it is usually not easy to load and unload grains, which makes the use of this equipment still somewhat inconvenient and often troubles users. Utility Model Content

[0004] The purpose of this utility model is to provide a grain dryer to solve the problem that although the drying equipment mentioned in the background art can be well applied, it is usually not convenient to load and unload grains, which makes the use of the equipment still inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grain dryer, comprising a main frame, a platform at the top of the main frame, a drying chamber at the edge of the top of the platform, an auxiliary frame on the surface of the main frame, a heating chamber at the bottom of the platform, a bidirectional fan at the bottom of the heating chamber, guide rails at the top of the platform on both sides of the heating chamber, one end of the guide rails extending to the outside of the drying chamber and connecting to the top of the auxiliary frame, a support platform slidably connected to the top of the guide rails above the auxiliary frame, a rectangular vent inside the support platform, a grain container at the top of the support platform above the rectangular vent, a baffle on the surface of the support platform, a pull handle installed at the center of the baffle surface, several casters installed at the bottom of both the main frame and the auxiliary frame, and an electrical control box on one side of the outer wall of the main frame.

[0006] Preferably, the upper surface of the support platform away from the baffle is provided with a first abutment seat, and the top of the support platform on both sides of the first abutment seat is provided with a second abutment seat. The first abutment seat and the second abutment seat are provided to abut against the first abutment member and the second abutment member to limit the pushing depth of the support platform.

[0007] Preferably, the top of the platform between the guide rails is provided with a first abutting member, and the top of the platform on both sides of the first abutting member is provided with a second abutting member. The first abutting member and the second abutting member are provided to abut against each other.
