Description

[Detailed description of the invention] (Industrial application field) The present invention is a method of removing grains by attaching an ejection device such as a flexible screw conveyor, auger, or chute to the ejection port of a grain container storing grains. The present invention relates to a grain delivery device for a grain container, which takes out grains from the container to an appropriate position.

(Prior art) Grain containers are as described in Japanese Utility Model Application Publication No. 171717/1983 and Japanese Patent Application Publication No. 172091/1988, etc.
It can be mounted on a truck or the like to transport grain, or installed in a barn and used for temporary storage of grain. The grains are taken out by attaching a delivery device such as a flexible screw conveyor or an auger to a takeout port provided at the bottom of one side of the grain container.

(Problem to be solved by the invention) The grain is taken out by opening the shutter provided at the take-out port with the unloading device attached to the grain container, but the grain container is not empty. There are cases where the unloading device is removed from the outlet and the grain container is used for transport operations. In this case, it is necessary to close the shutter and remove the unloading device from the outlet; however, due to carelessness, the unloading device may be removed with the shutter open and the grains discharged.

The present invention eliminates the need to leave the shutter open and discharge the grains from the grain tank when removing the unloading device from the outlet of such a grain container. .

(Means for Solving the Problems) Therefore, in the present invention, in a grain retrieval device for a grain container, in which a grain container 1 opened and closed by a shutter 24 is taken out at an outlet 11, and a carrying-out device 10 is detachably attached. A restrictor 36 is provided to restrict the removal of the carrying out device 10 in conjunction with the opening operation of the shutter 24, so that the carrying out device 10 cannot be removed when the shutter 24 is open.

(Operation and effect of the invention) When the unloading device 10 is attached to the outlet 11 of the grain container 1 and the shutter 24 is opened, this shutter 2
In conjunction with the opening operation of No. 4, the restriction tool 36 that restricts the removal of the unloading device 10 acts to restrict the unloading device 10.
Since the shutter 24 cannot be removed from the outlet 11 of the unloading device 10 with the shutter 24 open, it is no longer possible to discharge the grains.

(Example) As shown in FIGS. 7, 8, and 9, the grain container 1 can be loaded onto the loading platform of a truck 2 and used for storing grains such as unhulled rice or wheat for transportation work. It is installed in a barn and used to temporarily store grain harvested with a combine harvester, etc.

This grain container is formed into a rectangular box shape that is long from front to back, and frames 5, 6,
7 and 8 are erected to form a grain storage section.

The cross-feeding conveyor 3 is driven by a motor 9 installed on the base 1 or a motor installed on the unloading device 10 side, and the stored grains are removed from the take-out port 1 provided at the lower rear side.
1 and the unloading device 10 from the take-out port 11.
I am trying to take it out to the outside. This outlet 1
As shown in the figure, a flexible screw conveyor 12, an auger 13, a chute 14, and other unloading devices 10 can be appropriately installed depending on the distance from the grain container 1 to the take-out and supply position.

Incidentally, the grains are stored in the grain container 1 by directly charging them from above using an auger of a combine harvester or the like.

As shown in FIGS. 1 and 2, the internal structure of the base 4 is such that a receiving gutter 16 is provided at the lowest part of a bottom plate 15 that slopes downward from the left and right sides toward the center bottom. The horizontal conveyor 3 is connected to the front and rear side walls 17,1
It is pivoted to 8. Further, above the traverse conveyor 3, a flow plate 19 having a chevron-shaped cross section is supported by support beams 20 horizontally suspended between the front and rear side walls 17 and 18.
Adjustment plates 21 are slidably fixed at the lower left and right ends of the flow plate 19, and the amount of grain flowing from the side into the lateral conveyor 3 is adjusted by adjusting the gap between the bottom plate 15 and the bottom plate 15, which slopes downward toward the center. I'm trying to adjust it.

The horizontal feed conveyor 3 has a helical 23 on the rotating shaft 22.
The helix 23 ends slightly before the take-out port 11, and the grain feeding force is transferred to the take-out port 1.
I try not to work hard to the point just above 1. or,
On the take-out port 11 side, the flow plate 19 also forms a gap l in the longitudinal direction between it and the rotary shutter 24 that opens and closes the take-out port 11, so that when the take-out port 11 is clogged with grains, the cross-feeding conveyor 3 The forced grain is forced to overflow upwards.

On the outlet 11 side of the rotating shaft 22, a rotating cylinder 26 is pivotally supported on a boss portion 25 provided on the side wall 18, and the rotating shaft 22 is pivotally supported on the rotating cylinder 26 via a bearing 27. A rotary shutter 24 made of an arcuate plate is attached to the inner cavity side of the rotating cylinder 26 from the side wall 18, and a shutter lever 28 is attached to the outer side of the side wall 18.
and a clutch lever 29.

The shutter lever 28 is attached directly to the rotating barrel 26, and the rotating barrel 26 is rotated to rotate the rotary shutter 2.
4 rotates on the same axis as the rotating shaft 22 toward the lower side that closes the outlet 11 and the upper side that opens the outlet 11.

A disk 30 is fixed to the outer end of the rotating cylinder 26,
Attach the clutch lever 29 to this disc 30 with the bolt 31
It is supported by This bolt 31 is loosely tightened so that the clutch lever 29 can rotate.

The clutch lever 29 is connected by a wire 33 to a clutch 32 for intermittent driving of the traverse conveyor 3, and as shown in FIG. It's pulling. Numeral 34 is a pin that engages with the clutch lever 29 to prevent it from rotating, and is provided protruding from the disk 30 to prevent the clutch lever 29 from rotating.

Therefore, the shutter lever 28 is rotated 180 degrees to open the rotary shutter 24 (imaginary line state).
, the clutch lever 29 is pulled by the wire 33 and rotated to the position where the clutch 32 is engaged as the disk 30 rotates. In this state, the rotary shutter 24 is opened, the lateral conveyor 3 is driven, and the grains are taken out by the unloading device 10. However, if the unloading port 11 or the unloading device 10 becomes clogged, the clutch lever 29 Clutch 32 alone
Since the bolt 31 can be rotated in the direction of cutting, when the bolt 31 is rotated to a position beyond the fulcrum, it comes into contact with a pin 35 protruding from the side wall 18, turning the clutch 32 into a cut state and stopping the traverse conveyor 3. I can do it.

The clutch lever 29, which has been rotated to the position where the clutch 32 is disengaged, is moved over the fulcrum by the tightening force of the bolt 31 when the shutter lever 29 is returned to the closed position and rotated again to the open position, and the clutch lever 29 is moved to the position where the clutch 32 is engaged. Rotate to.

Further, the rotating tube 26 has a regulating member 36 made of a pin.
The machine frame 37 of the unloading device 10 is installed below the outlet 11 with the rotary shutter 24 in the open state.
It is located on the outside to restrict removal of the unloading device 10.

The left and right width D of the outlet 11 is as shown in FIG.
The rotary shutter 2 should be wider than the left and right width d of 6.
When the opening 4 is opened, the grains can easily pass through the outlet 11.

A transmission shaft 38 for driving the lateral conveyor 3 is pivotally supported on the lower side of the lateral conveyor 3.

In the embodiment shown in the figure, the lateral conveyor 3 is driven from the unloading device 10 side, and a pawl clutch 39 is biased toward the projecting side by a spring 40 at the output port 11 side of the transmission shaft 38. A pulley 41 is fixed to the shaft end outside the side wall 17 at the other end, and a belt 43 is wound between it and the pulley 42 fixed to the shaft end of the rotating shaft 22 of the traverse conveyor 3 to transmit power. I try to do this. Reference numeral 32 denotes a clutch that tensions and loosens the belt 43 to connect and disconnect power, and tensions the belt 43 and biases it to a state where power is transmitted.
By operating the clutch lever 29, the clutch 4
When the wire 33 connected to the belt 3 is pulled, the belt 43 is loosened and power transmission is cut off.

The unloading device 10 includes a spring-like screw conveyor 45 inside a flexible tube 44.
Insert the tip into the box-shaped transfer box 46,
A fastener 47 prevents it from coming off. In this embodiment, two screw conveyors 45, 45 are connected to a transfer box 46 as shown in FIG. I'm tightening it up.

Further, a claw clutch 49 is attached to the tip of one of the screw conveyors, and is engaged with the claw clutch 39 of the transmission shaft 38 to transmit the driving force of the motor provided on the take-out side of the carry-out device 10. ing.
