JPS592016Y2 - Remaining grain removal device on screw conveyor - Google Patents

Description

[Detailed description of the invention] The present invention is capable of moving up and down relative to the screw until the receiving gutter, which is disposed opposite to the lower part of the screw, is placed on the rotating roller. This invention relates to a device for removing residual grains from a screw conveyor, which is configured to be able to be inserted into and removed from a machine body by sliding.

Some of the conventional residual grain removal devices of this type are configured so that the screw receiving gutter itself can be directly removed from the machine in the transfer direction. Since the upper surface of the layer is in contact with the peripheral edge of the screw, a small portion of the grains may spill out and be left behind inside the machine when the receiving gutter is extracted. It was incomplete.

Next, in order to prevent the grains from being left behind inside the machine, a box body that can be inserted and removed along the longitudinal direction of the receiving gutter is further provided under the ejected receiving gutter, and the grains on the receiving gutter are placed inside the box. The structure was such that the box was dropped into the machine and the box was pulled out of the machine to dispose of the remaining grains.

However, the length of the gutter of the dryer used by farmers is approximately 2 meters, and in a narrow work shed and at a position lower than the knee, I have to shake it over and look into it several times. It is very painful to insert and remove the cable many times, and dust and debris get stuck in the gutter and the fitting part where it is inserted and removed.
In addition, corrosion such as rust is likely to occur, and there are many factors that prevent smooth insertion and removal, requiring extremely cumbersome work.

The present invention was devised to alleviate this cumbersome work, and was devised as a device that can completely remove residual grains from the screw conveyor without leaving even a single grain behind. To specifically explain what is implemented in the lower conveyor of a grain dryer as an example, 1 is a hopper room installed below a drying chamber (not shown) integrally with the drying chamber, in which hopper chambers are dropped from the drying chamber as appropriate. Collect the grains at the bottom.

Reference numeral 2 denotes a screw conveyor horizontally installed at the bottom of the hopper chamber 1, and a screw 3 and rising walls 4a, 4 placed oppositely below the screw 3 on the left and right and on the transfer starting end side.
b, and its transfer end is connected to a grain lifting machine, etc. (not shown).

Reference numeral 5 denotes a crank rotatably supported by the left and right side walls of the body 10 below the receiving trough 4, and a rotating roller 6 is mounted in the center.

An appropriate number of cranks 5 having rotating rollers 6 are arranged in the transport direction of the screw conveyor 2.
The receiving gutter 4 is placed on and supported by the rotating rollers 6 of the plurality of cranks 5, and is configured to be movable in the transfer direction.

In this case, although not shown, the receiving gutter 4 of the aircraft body 10
If accessories are placed on the extraction side (for example, a transfer screw or a transfer gutter that connects the transfer end of the screw conveyor 2 and the grain lifting machine), an opening/closing mechanism is installed on the wall of the machine body 10 at a location away from these accessories. A mechanism may be provided from which the receiving gutter 4 can be inserted and removed.

7 is a screw conveyor 2 with a handle 7' placed on the outside of the machine.
It is an operating rod extending in the transfer direction, and is integrally constructed with a connecting pin 9 rotatably pivoted to the free end side of a rotating piece 8 fixed to each crank 5.

Since the present invention is constructed as described above, when the operating rod 7 is moved as shown by the solid line in FIG. Then, move the receiving gutter 4 upward while it is placed on the rotating roller 6,
The receiving gutter 4 is fixed at this upward movement position.

In this state, the grains delivered from the drying chamber to the hopper chamber 1 and collected at the bottom thereof are transferred by the screw 3 onto the receiving trough 4, and are supplied to a grain lifting machine, etc. connected to the end of the transfer. be able to.

On the other hand, if you want to take out the grains remaining on the gutter 4 after the drying process is finished, move the operating lever 7 in the opposite direction to the above case, and the gutter 4 will move down. Since the contact between the upper surface of the layer of residual grains and the peripheral edge of the screw 3 is eliminated, if the receiving trough 4 is slid over the rotating rollers 6 and pulled out of the dryer, the residual grains inside will be removed one by one. The entire receiving gutter 4 can be pulled out of the aircraft without spilling anything.

As described above, the residual grain removal device for the screw conveyor according to the present invention can move up and down with respect to the screw while the receiving gutter installed oppositely below the screw is placed on the rotating rollers. In addition to configuring it so that
Since the receiving trough is configured so that it can be inserted into and removed from the machine body by sliding on a rotating roller in its downward movement position, it is possible to take out the remaining grains without taking out a single lost grain. At the same time, it can be taken out of the machine without leaving even a single residual grain, making it extremely suitable as a device for use in seed machines such as grain driers and threshing machines.
