Description

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

Problems to be Solved by the Invention In a grain dryer that repeatedly circulates and dries grains while flowing them down from the top of the drying chamber, the grains flowing down inside the drying chamber are
The hot air generated in the dryer crosses the drying chamber, and the grains are exposed to the hot air and are dried. In some cases,
When the grain is contaminated with a large amount of straw waste, the density of the grain flowing down in the drying chamber becomes paddy, and there is less resistance to the hot air flowing across the drying chamber, so the hot air passes quickly, and the hot air In some cases, grains flowing down the drying chamber are exposed to hot air for a short period of time, resulting in a decrease in drying speed.

Means for Solving the Problem This invention provides a feeding valve (2) located at the lower part of the drying chamber (1) for feeding out the grains, and a sensor (3) to measure the density of the grains flowing down the drying chamber (1). ), and when the detected amount is below a certain level, the delivery valve (2) increases the delivery amount.

Functions and Effects of the Invention By rotating the delivery valve (2), the grains are delivered down and dried in the drying chamber (1).
1) When the grains flowing down inside the drying chamber (1) are grains with many grains attached to branches or 59 grains with a lot of straw waste mixed in, the grain a density in the drying chamber (1) may be coarse. When the detected amount of grain density flowing down the drying chamber (1) by the sensor (3) becomes below a certain level, the rotational drive of the feeding valve (2) is quickly linked to dry the drying chamber (1). Since the flow rate of the grains in the dryer becomes faster, the circulation of the grains housed and dried in the dryer becomes faster, and therefore the number of circulation increases, and the grains attached to the dryer become clogged.
Since straw waste and the like are quickly discharged outside the machine along with the drying exhaust air, the grain density flowing down the drying chamber (1) quickly becomes dense, and the ventilation resistance of the hot air crossing the drying chamber (1) increases. The time the grains are exposed to hot air increases, increasing the drying rate.

Embodiment In the illustrated example, the wall of the dryer (4) has a rectangular shape in plan view that is long in the front and back direction, and is composed of front and rear wall plates (5), (5) and left and right wall plates (6), (6). At the top of this machine wall is the ceiling (7
), (7). A lower helical transfer gutter (8) is provided in the center of the machine wall in the left-right direction and extends from front to back and has a cross-shaped shape when viewed from the front. A room (9) is formed, and this grain collection room (9) is formed.
) A vertical drying chamber (1), (1) is formed between the left and right ventilation mesh plates and communicated with each other, and this drying chamber (1).

At the bottom of (1), delivery valves (2), (2) are provided. An inclined plate is provided above each ventilation mesh board, a partition board is provided below, a ventilation chamber (10) is formed between the inner ventilation mesh boards, and the front wall board (
The ventilation chamber (12) communicates with the burner (11) provided in the rear wall plate (5) and is formed between the left and right outer ventilation net plates and the left and right wall plates (6), (6). 5) Exhaust air #l (
+3). A tempering chamber (14) is formed above the drying chambers (1), (1), and an upper helical transfer is carried out along the ceiling plates (7), (7) above the tempering chamber (14). A gutter (15) is provided, and a supply port is opened in the center of the upper helical transfer gutter (15) for supplying the grains to be transferred into the conditioning chamber (14). ) has been established.

The grain raising machine (17) is removably attached to the front part of the front wall plate (5), and a packet conveyor (18) belt is stretched between the upper and lower pulleys inside, and the upper pulley is freely movable up and down with g4 sections. A motor for driving the packet conveyor (+8) is provided on the upper part of the outer wall, and a dispensing cylinder (19) is connected to the front end of the upper helical transfer gutter (15) at the upper end of the grain hoist (17). The front wall plate (5) is located on the outside and is detachably provided,
A supply gutter (2) is located at the lower end of the front wall plate (5) and communicates with the front end of the lower helical transfer gutter (8).
0), and within this supply gutter (20), the drying chamber (
1) provide a sensor (3) for detecting the density of grains in the grain;
This sensor (3) consists of a rotatable mouth-shaped detection plate and a switch, and detects when the amount of grains transferred and discharged into the supply gutter (20) by the lower helical transfer gutter (8) is below a certain level. When the sensor (3) detects the amount, the detection plate moves downward and switches on to detect the amount.When the amount exceeds a certain level, the detection plate moves upward and turns off the switch.At the same time as the sensor (3) detects the (22) is an electrically interlocked configuration.

(23) is a motor pulley, and (24) is a two-stage pulley (24) having a large diameter part and a small diameter part fixed to the helical shaft end of the lower helical transfer gutter (8). (24) Belt (2
5) is a configuration in which the hook is passed, and (26) is a speed change pulley, and this speed change pulley (26) and the two-stage pulley (24)
(27) is a structure in which the hanging is passed,
(28) is a tin rocket, (28) is the delivery valve (2), (2) is a sprocket fixed to the shaft end,
(30) is a floating sprocket, and these tin locations 7
) (2B), (29), (30), Toni Cheno (3
1) is a passed configuration. (32) is a tension device, and the solenoid (22) is electrically interlocked by detection by the sensor (3), and this solenoid (22) pushes the tension device (32).
The speed change pulley (2θ) rotates faster, the sprocket (29) fixed to the shaft end of the delivery valve (2) is driven to rotate faster, and the delivery valve (2) is accommodated in the dryer (4). This structure allows the grains to be circulated quickly.

An operation box (33) and a moisture measuring device (21) are removably provided on the front wall plate (5).

The hot air generated from the burner (11) provided on the front wall plate (5) is sucked by the exhaust air 41I (13) provided on the rear wall plate (5), thereby creating a drying chamber (formed with a ventilation mesh plate). 1) is cross-ventilated, and the grains stored in the drying chamber (4) are dried while being exposed to this hot air while flowing down inside the drying chamber (1), and are fed out to the tenth section by the feeding valve (2). is transferred to and discharged into the supply gutter (20) by the lower helical transfer gutter (8), transported to the upper part by the grain hoist (17), and then transferred to the upper helical transfer gutter (15).
) to the supply port, and is transferred to the conditioning chamber (I) by the diffusion plate (1B).
4) When the dryer (4) is evenly scattered and returned to the dryer (4) and is circulated and dried to reach the specified moisture content, the operation box (33) automatically controls the dryer (4) to automatically stop the dryer (4). When the grains to be dried are grains with a lot of ramus adhesion or grains with a lot of tJ debris mixed in, the density of the grains in the drying chambers (1), (1) becomes coarse. The delivery valve (2), (2
