Description

[Detailed description of the invention] Industrial applications The present invention relates to a grain transfer device for a grain dryer.

Conventional technology In the past, grains were fed from the storage chamber to the drying chamber by rotating a feeding valve, and then flowed down into a grain collection gutter provided at the bottom of this feed-out valve, using a transfer spiral provided in this grain collection gutter. This collecting trough and transfer spiral for transferring grain to the grain section were devices installed in a horizontal position.

Problems to be Solved by the Invention Grain is fed from the upper storage chamber to the lower drying chamber by rotation of a feeding valve, and flows into a grain collecting gutter located below the feeding valve. It is transferred to one side by a transfer spiral and discharged into a supply gutter, flows down the feed gutter, and is supplied into a grain raising machine, which transports it to the upper part and circulates it back into the storage chamber. In a dryer that repeatedly passes hot air generated by a burner through the drying chamber and exposes the grains flowing down the drying chamber to the hot air to dry them, as the grains flow down inside the feeder, If the inclination angle of the bottom of the supply gutter is not above a certain level, the grains will stagnate and will not flow down.
This inclination angle needs to be a steep inclination angle, and if the inclination angle is set to a steep inclination angle, the distance between the transfer spiral and the bottom of the lift i9m will be longer, and the total height of the dryer will be higher. Installation may be less adaptable to drying workplaces with low ceilings.

Means for Solving the Problems This invention provides a delivery valve (3) that allows the grains to be delivered from the storage chamber (1) to the drying chamber (2) and flows down. A grain collection gutter (4) and a transfer spiral (5) for collecting grains and transferring them to one side are provided so that the grain transfer direction side is inclined upward, and this transfer spiral (5)
A supply gutter (6) is provided at the terminal end, and this feed gutter (6) communicates with the lower end of the grain raising machine (7) that conveys the grains to the upper part and circulates them back into the storage chamber (1). The structure of the grain transfer device of the grain dryer is as follows.

Effect of the invention The grains stored in the dryer are fed out from the storage chamber (1) into the lower drying chamber (2) by rotating the feeding valve (3).
The grains flow down into the grain collection trough (4) and are transferred by the transfer spiral (5) to the front part of the dryer and discharged into the supply trough (6). It flows down and is supplied into the grain raising machine (7), and is transported to the upper part by this grain raising machine (7) and stored in the storage chamber (1).
), the hot air generated by the burner is passed through the drying chamber (2), and the grains flowing down the drying chamber (2) are exposed to the hot air and dried.

Effects of the Invention According to this invention, the grain collection gutter (4) through which the grains are collected and the transport spiral (5) through which the grains are transported are provided with the front side of the dryer slanted upwards, so that the grains can be easily transported. The grains are transported by the spiral (5) and discharged into the supply gutter (6), and the bottom surface of the feed gutter (6) where the grains flow down can be made at a steep angle. There is no stagnation, and since the transfer spiral (5) is raised upward at the front, the total height of the dryer can be maintained even if the inclination angle of the bottom of the supply gutter (6) is steep. Since the dryer is not too high, installation flexibility of this dryer is expanded even in drying workplaces with low ceilings.

Embodiment In the illustrated example, the a-wall (9) of the dryer (8) has a rectangular shape in plan view that is long in the front and back direction, and is made up of front and rear wall plates and left and right wall plates. (8) has a configuration in which an operating device (lO) for controlling starting, stopping, etc. is removably attached.

A grain collection gutter (4) having a V-shape in front view is provided between the horizontal wall (9) at the center of the lower part and extending in the front-rear direction, with the front wall plate side inclined upward. A supply gutter (6) is provided on the outer wall of the front wall board outside the grain gutter (4), and this grain gutter (4)
) and the supply trough (6), a transfer spiral is rotatably supported, and above the grain collection trough (4) there are vertically arranged drying chambers (2), (
2) is formed between the left and right ventilation mesh plates to communicate with each other, and at the bottom of this drying chamber (2), there are rotatably supported feeding valves (3), (3) that feed and flow down the grains. This is the configuration.

A hot air chamber (11) is formed between the inner ventilation mesh plates, and communicates with a burner (13) built in a burner case (12) provided in the front wall plate. Air exhaust chambers (14), (10) are formed between the ventilation net plate and the left and right wall plates, and are in communication with an air exhaust fan (15) provided in the rear wall plate. A sloped plate is installed on the upper side of the net plate,
A partition plate is provided on the lower side, and a motor (1B) is provided at the bottom of the rear wall plate, and this motor (1B) operates the transfer spiral (5), the delivery valves (3), (3). , and the exhaust fan (15), etc., are configured to be rotationally driven.

A storage chamber (i) is formed above the drying chambers (2), (2), and ceiling plates (17), (17) are formed above the storage chamber (1).
A transfer gutter (18) equipped with a transfer spiral is provided along these ceiling plates (, 17), (17), and this transfer gutter (1
8) A supply port for supplying the transferred grains into the storage chamber (1) is opened in the center, and a diffusion plate (19) is provided at the bottom of this supply port.
), and the grains are transferred to the storage chamber (1) using this diffusion plate (19).
It is configured to diffuse and reduce evenly inward.

A fuel tank (20) is installed at the front of the dryer (8), a fuel pump (21) is installed at the outer side of the lower plate of the burner case (12), and a fuel hose is connected to the fuel tank (20). The configuration is such that fuel is supplied into the burner (13) through a fuel pump (21) and a fuel supply pipe, and combustion air is supplied to the burner case (12) by a blower a (
22) is rotated by a blower motor (23) to blow air into the burner (13) through a blower duct.

Grain raising It (7) is attached to the front part of the front wall plate, and inside there is a packet conveyor (20 belts are stretched between the upper and lower pulleys, and between the upper end and the starting end of the transfer gutter (18) is a packet conveyor (20 belts). A projecting tube (25) is provided to communicate with the lower end and the supply gutter (6).
