Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for disposing a grain discharging screw at the bottom, disposing a flow rate adjusting plate above the grain discharging screw, and transferring the grain flowing down to the grain discharging screw. The present invention relates to a Glen tank provided with a stirring mechanism for stirring particles.

[0002]

2. Description of the Related Art Conventionally, in this type of Glen tank, when the grains in the Glen tank form a lump or flow down to a grain discharge screw, a grain is formed between a flow control plate and the tank inner wall. The stirring mechanism was constantly driven so that the particles did not cause a bridging phenomenon.

[0003]

However, in the above-mentioned conventional apparatus, since the stirring mechanism is constantly driven, there is a high possibility that the grains are damaged by the stirring mechanism, and the stirring mechanism is driven. As a result, the load on the prime mover is increased, so that there is a disadvantage that the margin for driving other devices is reduced. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a Glen tank that can reliably reduce the power of a stirring mechanism as much as possible while preventing the flow of grains to a grain discharge screw without clogging. And

[0004]

In order to achieve the above object, a Glen tank according to the present invention has the above-mentioned structure, and has a grain tank in a space between the flow rate adjusting plate and the grain discharging screw. A first detector for detecting the presence / absence of grains, a second detector for detecting the presence / absence of grains in the grain storage space above the first detector, and driving means for driving the stirring mechanism are connected. The control means outputs an output signal for driving the driving means only when both the result of detection of the absence of grain by the first detector and the result of detection of the presence of grain by the second detector are input. This is a characteristic configuration. The operation and effect of this characteristic configuration are as follows.

[0005]

That is, when the presence of a grain is detected by both the first detector and the second detector, when the presence of a grain is not detected by both the first detector and the second detector, or When the presence of the grain is detected by the first detector and the presence of the grain is not detected by the second detector, the grain is flowing without clogging, or the grain has disappeared from the Glen tank. As a result, the stirring mechanism is stopped so as not to be driven uselessly,
When the presence of the kernel is detected by the second detector and the presence of the kernel is not detected by the first detector, the kernel is in the Glen tank but does not flow down to the kernel discharge screw, that is, Since it is determined that clogging has occurred in the middle of the flow and the stirring mechanism is activated only at that time,
When clogging occurs, clogging is surely cleared, and when it is not necessary to operate the stirring mechanism, the stirring mechanism is automatically stopped.

[0006]

[Effects of the Invention] Therefore, since the stirring mechanism is not driven at all times, the damage to the grains by the stirring mechanism can be reduced, and the stirring mechanism is stopped when no clogging occurs. Advantages such as labor saving can be achieved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show a Glen tank 1 mounted on a combine as an example of a Glen tank according to the present invention. The Glen tank 1 is mounted on the fuselage in a state of being juxtaposed beside the threshing device 2 and
The grains that have been threshed by the threshing device 2 are fed and fed by the feeding device 3.

[0010] As shown in FIG. 1, the grain in the Glen tank 1 is taken out to the center of the bottom of the Glen tank 1, which forms a tapered inclined surface 1 a at the left and right center. The grain discharge screw 4 is disposed along the front-rear direction, and the grain load in the Glen tank 1 is received at a position above the grain discharge screw 4,
A mountain-shaped flow rate adjusting plate 5 is provided along the grain discharge screw 4 to limit the flow of the grain to the grain discharge screw 4. An unloader device 6 that lifts and discharges the conveyed grains is provided continuously outside the wall of the grain tank 1 at the lower end of the grain discharge screw 4 in the conveying direction.

As shown in FIG. 1 and FIG.
In the vicinity of the upper portion, a plurality of stirring rods 9 突 project upward from a swing shaft 7 laid back and forth in the Glen tank 1, and a support rod 8 with the stirring rod 9 敷 laid in the front-rear direction. And constitute a stirring mechanism 10. An oscillating shaft 7 extending to the outside of the Glen tank 1 is connected to an end of a passive arm 7a connected to the oscillating shaft 7 by an electric motor 11 as a driving means.
Of the drive mechanism 12a of the crank mechanism 12 provided to convert the rotational power of the output shaft into reciprocating power so that the stirring rod 9 # swings reciprocally by the drive of the electric motor 11. Make up.

A second detecting means for detecting the presence or absence of a grain near the upper end of the left and right inclined surfaces 1a, 1a at the bottom of the Glen tank 1.
A detector 14 is provided, and a first detector 13 for detecting the presence or absence of kernels is provided at a position near the kernel discharge screw 4 below the extension of the edge of the flow rate adjusting plate 5. .
The first detector 13 and the second detector 14 are connected to a control circuit 15 as control means, and the control circuit 15 is also connected to the electric motor 11. In the control circuit 15, when a non-detection signal accompanying the detection of the absence of a grain is input from the first detector 13 and a detection signal according to the detection of the presence of a grain is input from the second detector 14, A drive signal for driving the electric motor 11 is output.
Further, the control circuit 15 is set so as not to output a drive signal for driving the electric motor 11 in other cases of the above signal input conditions. Therefore, only when the clogging occurs without the grains flowing down to the grain discharge screw 4, the stirrer 10 is driven to loosen the clogged grains to eliminate the clogging, and when no clogging occurs,
That is, when the grains are flowing down normally and when there is no grain in the Glen tank 1, the stirring mechanism 10 is stopped.
