Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hot air guiding device for a grain dryer. The hot air flowing through the burner and the cold air flowing around the outer circumference of the burner are allowed to flow in, and the drying air is passed across the drying chamber through the air passage while merging with -2 deviation left and right from the front in the direction of inflow. If the hot air flowing through the burner is not sufficiently mixed with the cold air flowing around the burner, the temperature of the hot air flowing across the drying chamber may become uneven, reducing the drying speed, or causing the hot air to flow in areas where the temperature is locally high. arise.

The present invention aims to eliminate such drawbacks, and therefore takes the following technical measures. That is, burner (1)
The hot air generated by the burner (1) is made to flow in together with the cold air flowing around the outer periphery of the burner (1), and the air is guided to the drying chamber (2) while deflecting from the front of the inflow direction to the left and right and merging the air.
In 3), a hot air guide device for a grain dryer is provided with a resistor (5) that provides resistance to the air flowing while being offset laterally from the front face of the burner (1).

This invention has the following technical effects due to such a configuration. In other words, the grains stored in the dryer are transferred to the drying room (
In the dryer that dries while circulating the grain from 2) to the storage room via the grain raiser, the hot air generated by the burner (1) and the cold air flowing around the outer periphery of the burner (1) are made to flow in, and the The drying chamber (
This drying room (
The grains are dried by blowing air across the burner (1). By providing it inside the burner (1), the cold air flowing around the outer periphery of the burner (1) is drawn inward by the resistor (4), and the burner (1)
) is mixed with the hot air generated in the drying chamber (2) and passed through the drying chamber (2), so the temperature of the hot air is made uniform over the entire drying chamber, and uniform and stable drying can be achieved.

To explain the example shown below, the dryer frame (5) has a rectangular shape in plan view that is long in the front and back direction, and has front and rear wall plates (6), (6), and left and right wall plates (7), (7). However, this wall board-L has a structure including ceiling boards (8) and (8). This machine frame (5
) is provided with a lower helical transfer gutter (9) located at the center bottom in the left-right direction and extending in the front-rear direction and having a shape of a letter 7 in front view. Room (1
0) is formed of a grain collecting plate, and the edge of this grain collecting plate overlaps and coincides with the upper edge of the lower helical transfer gutter (9). A vertical drying room (2) is formed above the grain collection room (10) between two left and right ventilation mesh plates, and is arranged in four rows. The lower edges of these left and right outer ventilation mesh plates are connected to the grain collecting room (10), and the four-row drying room (2) is communicated with this grain collecting room (10). A feed roll (12) is provided at the bottom of this drying chamber (2). (13) is an inclined plate above the outside of the ventilation mesh plate, (14) is an exhaust room partition plate, (15) is a mountain-shaped inclined plate above the ventilation mesh plate, and (16) is an air duct partition plate. An air passage (3) is formed between the inclined plate (15) 1 ventilation net plate and the air passage partition plate (te), and the front wall plate (6)
A ventilation chamber (1) is formed between the left and right outer ventilation net plates and the left and right wall plates (7), communicating with the burner (1) provided in the section.
7) and the ventilation chamber (17) formed between the central ventilation mesh board.
is communicated with an exhaust fan (18) provided on the rear wall plate (6). Above the drying chambers (2), (2) is a storage chamber (1).
9), and a ceiling plate (8), (
8), and an upper helical transfer gutter (2o) is provided along this ceiling plate (8), and this upper helical transfer gutter (2o) is rotationally driven by a pair of gears in the center of the ceiling plate (8). The opening is opened on the diffusion plate (21), and the grains to be transferred and supplied can be scattered and supplied into the storage chamber (18) by the diffusion plate (21). A box-shaped wind barrel (22) forming an air passage (3) communicating with the air passage (3) formed between the ventilation mesh plates is provided on the front wall plate (6). ) A resistor (4) that provides resistance to air blowing is provided on the front wall plate (6) in a V-shape in plan view and with a gap above and below the wind cylinder (22) in side view. A burner case (23) containing the burner (1) is detachably attached to the front part of the body (22).This burner (1) and burner case (23)
A ventilation interval is provided between the two to allow outside air to flow in.

91 grain machine (24) has a packet conveyor (25) inside.
A belt is stretched between the upper and lower pulleys, and the upper pulley can be adjusted and moved downward, and the - side supply gutter (26) is communicated with the front end of the lower helical transfer gutter (9). The machine frame (5) is removably attached to the front wall plate (6) located outside, and the dispensing cylinder (27) at the upper end is connected to the -1 part of the helical transfer gutter (
20), and is located outside the front wall plate (6) and is detachably provided.

An operation box (28) and a moisture measuring device (11) are provided on the front wall plate (6).

Hot air generated from the front part of the machine frame (5) front wall plate (6)/heater (1) and cold air flowing around the outer periphery of this burner (1) are transferred to the rear wall plate (6) and the wind fan (18). When you are sucked in by the wind body (
The hot air and cold air are mixed in the resistor (4) in 22) and are ventilated across the drying chamber (2) formed between the ventilation mesh plates.
The grains stored in the machine frame (5) are dried while being exposed to the hot air while flowing down the drying chamber (2), and are fed to the lower part by the feed roll (12) and sent to the lower helical transfer gutter. (9), sent to the grain hoist (24), and yI

Claims (1)

[Claims] An air passage (3) that allows the hot air generated by the burner (1) to flow in together with the cold air flowing around the outer periphery of the burner (1), and guides the air to the drying room (2) while deflecting and merging from the front in the direction of inflow to the left and right. A hot air guide device for a grain dryer is provided with a resistor (4) that is offset laterally from the front face of the burner (1) and provides resistance to the air flowing.
