DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain drying machine, in which grains which are dried by a grain dryer and discharged from an elevator mounted on the grain dryer are installed at a higher place than the grain dryer. In a grain feeder such as a slower used to feed the grain to a grain storage tank, the feed rate of the grain feeder that adjusts the feed rate of the grain to be supplied to the feeder to adjust the feed rate to the capacity and the properties of the grain. The present invention relates to improvement of an adjusting device.

[0002]

2. Description of the Related Art As shown in FIG. 1, a feed rate adjusting device in the above-mentioned grain feeder is specifically mounted on a grain feeder 2 of a slower type for frying mounted on a grain dryer 1. Explaining in more detail, the side of the body 10 of the grain dryer 1 is provided with a discharge port of the elevator 11 provided in parallel with the body 10, and a grain filling hanger which is laid on the top of the body 10. A chute 20 for grain discharge, which is switchably communicated with the screw conveyor device 12, is provided, and a lower end of the chute 20 is connected to an upper part of a receiving hopper 21 mounted on an outer surface of the machine body 10, 2 is formed on a chute for supplying grain to the hopper 21, and a lifting wheel for grain is provided on the shaft end of the conveyor shaft at the end side of the discharge conveyor 22 provided at the bottom in the hopper 21 as shown in FIG. Attach 23 and surround it around And 支架 24 to the body 10, by connecting the AgeKoku cylinder 25 to the shoulder portion of the casing 24, constitute a OkuKoku device 2 of Surowa form for cereal fried.

[0003] A supply amount adjusting device 3 provided to adjust the amount of grains supplied to the grain sending device 2 includes:
As shown in FIG. 3, a butterfly valve-shaped adjustment plate 3 that rotates around a rotation fulcrum 30 is provided on the lower surface side of the opening 200 at the lower end of the grain supply chute 20 connected to the upper surface side of the hopper 21.
1 is provided so that it can be adjusted to a desired rotation angle, and the opening angle of the opening
By adjusting the opening degree of the grain, the amount of the flowing grain is changed and adjusted.

[0004]

The grain supply adjusting device 3 in the above-mentioned grain feeder is intended to stabilize the flow of the grain induced by the chute 20 for introducing the grain into the hopper 21. The top plate of the hopper 21 is formed so as to be orthogonal to the inclined chute 20 to facilitate machining.

[0005] From this, the flow of the grains flowing down in the chute 20 is reduced as shown by the double-line arrow in FIG. Since the flow of the flow along the inner surface of the floor 20a due to the inclination of the floor 20 occurs, unless the kernels are completely clogged at the lower end side of the chute 20, the flow rate of the flow through the adjustment of the opening of the adjustment plate 31 is adjusted. Since the adjustment is not effective, there is a problem that the clogging of the grain is likely to occur. In addition, if the opening degree is increased, almost no flow rate adjustment is performed. There is a problem that stable flow rate adjustment cannot be performed only by adjusting the degree.

[0006]

An object of the present invention is to solve the above-mentioned problem that has occurred in the means for adjusting the supply amount of grains in a conventional grain feeder. It is an object of the present invention to provide a new means capable of stably adjusting the flow rate only by operating an adjusting plate 31 provided in the lower opening 200 to change the opening thereof.

[0007]

According to the present invention, as a means for achieving the above-mentioned object, a cylindrical chute for supplying grains is provided in a hopper for receiving grains in a grain feeding device. Attached at a predetermined angle and connected, the ceiling wall of the hopper connecting and connecting the opening at the lower end side of the chute is formed on an inclined wall inclined to a posture orthogonal to the axis of the chute 0, At the opening at the lower end of the chute, a shutter plate is provided to slide along the ceiling wall from the side opposite to the direction of inclination of the chute to expand and contract the opening of the opening, and the floor of the inner wall of the inclined chute is installed. On the side that will be the surface,
On the upper side of the opening formed between the leading edge of the shutter plate in the sliding direction and the edge of the opening chute on the inclined direction side, on the side that becomes the ceiling surface of the inner wall of the cylinder wall of the inclined chute. An object of the present invention is to provide a feed amount adjusting device in a grain feeding device in which a slant guide plate protruding downwardly inclined is provided.

[0008]

According to the means of the present invention, the inclined chute 2
The grain that flows down along the inner surface of the side 20a that becomes the floor due to the inclination of the chute 20 in the inner surface of the cylindrical wall of 0 is formed by the inclined guiding plate 43 provided on the side 20a that becomes the floor of the cylindrical wall. The side 20b of the cylindrical wall of the chute 20 which will be the ceiling surface
At a position on the lower surface side of the ceiling wall 210 of the hopper 21 and on the opposite side to the inclination direction of the chute 20 from the opening 200 on the lower end side of the chute 20, 4 collides with the upper surface of a shutter plate 41 provided so as to rotate along the lower surface of the ceiling wall 210 toward the lower surface of the opening 200, and as shown by a double-line arrow in FIG. Flows toward the side 20a that becomes the floor surface of the cylindrical wall of the hopper 21, and is guided from there to the upper surface of the shutter plate 41 inclined along the ceiling wall 210 of the hopper 21, and the front edge 42 of the shutter plate 41. It flows into the opening w formed between the opening 200 and the edge 200a of the opening 200 on the inclined direction side of the chute 20, and flows into the hopper 21 from the opening w.

For this reason, the inside of the chute 20 flows down along the inner surface of the side 20 a which is the floor of the cylindrical wall of the chute 20 and the front edge 42 of the shutter plate 41 and the side 20 a which is the floor of the cylindrical wall. The flow of the grain that directly flows into the opening w formed therebetween is reduced so as to almost disappear, and the grain flowing down in the chute 20 is reduced by the shutter plate 4.
1 and flows through the opening w through the upper surface of the hopper 1. Even if the amount of grains flowing down in the chute 20 is small, the opening degree of the opening w due to the rotation of the shutter plate 41 expands and contracts. The flow rate of the grain flowing into the inside 21 can be adjusted appropriately.

[0010]

Next, an embodiment will be described in detail with reference to the drawings. In the drawings, the same reference numerals are used for components having the same effects as those of the conventional means.
