Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grain discharging device in a conveyor that transfers grains at the inner bottom of a transfer gutter by sliding lugs. Since a conveyor has a lug that slides on the bottom surface, if a discharge port is provided at the bottom of the transfer gutter and a shutter is provided to open and close it, a step will be created between the bottom surface of the transfer gutter and the shutter surface. This makes it easy for the lower edge of the lug to catch on this step. The present invention eliminates these deficiencies with a simple configuration.

For this reason, the present invention has taken the following technical measures. That is, the shutter plates 1 and 2 which rotate in the vertical direction are supported on their shafts, and the shutter plates 1 and 2 are rotatable in the vertical direction.
A shutter frame 8 with bottom edge frames 6 and 7 attached to the front and rear edges of the opening 12 is placed on the same plane as the opening closing position by upward rotation of 2, and the lug 9 is slid thereon. A grain discharge conveyor is provided which is removably installed at the grain discharge port 12 at the bottom of a transfer gutter 10 for transferring grains, with the upper surfaces of the bottom edge frames 6 and 7 being flush with the bottom surface of the transfer gutter. The configuration of the device.

With this configuration, the present invention has the following technical effects. That is, the grains in the transfer gutter 10 are transferred to the lug 9 in sliding contact with the bottom surface 11.
When the shutter plates 1 and 2 close the opening 5, the shutter plates 1 and 2 close the opening 5.
The grains are transferred by sliding also on the upper side of the shutter plate 2, but when the shutter plates 1 and 2 are rotated downward to open the opening 5, the grains are transferred downward from the opening 5. Despite the fact that the shutter plates 1 and 2, which perform such opening and closing operations, also serve as a part of the bottom surface 11 of the transfer gutter 10 when closed, the shutter plates 1 and 2 are The shutter plates 1, 2 and the bottom frames 6, 7 are placed on the same plane, with the upper side in the closed position and the upper side of the bottom frames 6, 7, which are to form the bottom surface on which the lug 9 slides, placed on the same plane. 7 are integrally attached to the shutter frame 8, and this shutter frame 8 is attached to the grain discharge port 12 of the transfer gutter 10. Therefore, the bottom surface 11 of the transfer gutter 10 and the bottom edge frames 6, 7 By assembling on the same plane with
1. In particular, the grain outlet 12 is not easily distorted by the shutter frame 8, and the lugs 9 can be brought into smooth sliding contact to transfer the grains. Furthermore, the shutter plates 1 and 2 can be easily attached and can be opened and closed smoothly.

In the drawing, the transfer gutter 10 is installed horizontally above the grain storage tanks of a grain drying device, etc., and the grain discharge port 12 is arranged above each grain storage tank. However, the chain 13 is wound between the sprockets mounted on the front and rear ends of the transfer gutter 10, and the chain 1
3 is provided with lugs 9 at regular intervals, and the lower edges of the lugs 9 are brought into sliding contact with the bottom surface 11 to the full width, allowing rotation.

The shutter frame 8 is made of sheet metal and has a rectangular cylinder shape in plan view, and bottom edge bodies 6 and 7 are fixed to the upper end with bolts 14 in correspondence with the front and rear edges of the discharge port 12. At the front and rear portions of the bottom edge frames 6 and 7, seats 15 for receiving the ends of the bottom surface 11 are fixed to the shutter frame 8 with bolts 16. The left and right upper ends of this shutter frame 8 form mounting pieces 17 bent inward,
It can be overlapped and opposed to a mounting piece 18 which is provided on the outer surface of the side plate of the transfer gutter 10 to protrude horizontally from front to back. Both mounting pieces 1
The shutter frame 8 can be attached by tightening 7 and 18 with bolts 19. 20
extends in the front-rear direction of the central part of the opening 5 and has an upper surface flush with the upper surfaces of the bottom edge frames 6, 7, so that both 6, 7
It is a rail connected in between.

The shutter plates 1 and 2 are rotatably attached to the shutter frame 8 by shafts 3 and 4 at their outer ends, and are made of synthetic resin. An arm 21 is fixed to both the front and rear ends of each shaft 3, 4, and a tension spring 23 is elastically biased between this arm 21 and an arm 22 fixed at an appropriate position on the shutter frame 8. , 4 are elastically rotated by the spring 23 from an intermediate rotational position to a closing side and an opening side in a so-called tumbler configuration. 24 is a spring that generates friction between one end of one shaft 4 and the shutter frame 8, and the frictional resistance of this spring 24 prevents the rotation of the shutter plate 2 on the side where this spring 24 is located rather than the shutter plate 1. I'm in a late relationship.

25 is an arm fixed to each shaft 3, 4, and a string 26 is tied to the hole at the tip, one end of this string 26 is wrapped around a rotatable pulley 27 around the shutter frame 8, and the other end is connected to a guide 28 hole. The shutter plates 1 and 2 can be opened and closed by inserting the string 26 through the string 26 and pulling it in either direction. Also, the ends of the string that are stretched around the pulley are connected to each other, and by pulling this, the left and right shutter plates 1 and 2 simultaneously rotate in the closing direction, and the other end can be connected and pulled. It may also be configured so that it can be rotated in the opening direction at the same time.

The center portions of the bottom edge frames 6, 7 protrude in a triangular shape toward the opening 5, and opposite to these protruding slanted edges 29, 30, there are slanted edges 31 at the front and rear ends of the shutter plates 1, 2 that conflict with these. , 32 are formed.

Next, the operation of the above example will be explained. When the chain 13 is rotated in the direction of the arrow A, the lug 9 slides on the bottom surface 11 of the transfer gutter 10, and the grains to be supplied to the starting end of the transfer gutter 10 are transferred in the same direction. When the grains are transferred onto the discharge port 12 and the opening 5 is closed by the shutter plates 1 and 2, the grains pass from the bottom surface 11 onto the bottom edge frame 7 and then to the shutter plates 1 and 2. 2 and then radially over the bottom edge frame 6 to reach the front bottom surface 11.

Further, when the opening 5 is opened by opening the shutter plates 1 and 2, grains are discharged from the opening 5 into the lower grain storage tank.

When the shutter plates 1 and 2 are closed, the spring 23
However, the shutter plate 2, which is simultaneously activated by the friction of the spring 24, closes a little later than 1, and when this closes, the shutter plate 1,
The front and rear edges of the shutter plates 1 and 2 are pressed against the bottom frames 6 and 7, and the upper surfaces of these shutter plates 1 and 2 are pressed against the bottom frames 6 and 7, respectively.
The top surface 7 and the bottom surface 11 are formed on the same plane to smooth the transfer of grains.

In addition, each shutter plate 1, 2 is connected to the outer shaft 3, 4.
However, the shafts 3 and 4 may be provided in the center so that the shutter plates 1 and 2 can rotate downward from the center, or the shafts 3 and 4 may be opened in the same way. It may be provided laterally in the front and rear portions of the portion 5 so as to open front and rear, or it may be provided in the front and rear central portion of the opening portion 5 with the shafts 3 and 4 oriented laterally.
