Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a grain conveyor.

[Conventional technology and problems]

Particularly in recent years, as combine harvesters have become larger, grain (paddy) harvested and threshed in the field is transported by trucks or trailers equipped with a tilting mechanism (dump type), and grain dryers are installed in farmers' workplaces. There is a tendency for work to efficiently supply water to storage tanks, etc. in a short time. Therefore, in place of the conventional small-sized grain conveyor, a hopper with a length and width that can directly receive grain unloaded from the bed of a truck or trailer, and the grain stored in the hopper is used. A large grain conveying machine is required, which conveys the grains to one end of the hopper and then directly to the grain dryer or storage tank using a grain thrower, etc., and this type of machine has already been developed by the applicant. 56−32523, but
Since the hopper is long and rectangular to match the width of the loading platform of a truck, the screw transporting body is naturally long, and as a result, the middle part of the screw transporting body deforms due to the weight of the grain inside the hopper. Problems such as bending) and increased rotational horsepower consumption occurred.

In order to solve these problems,
As shown in Japanese Utility Model Publication No. 13927 and Japanese Utility Model Publication No. 57-22515, a flow plate with a mountain-shaped end face is provided above the screw transfer body provided in the hopper valley, and both edges of the flow plate and the hopper are connected to each other. A slide shutter that slides along the flow plate is provided at the inflow port formed between the flow plate and the bottom plate, and the left and right slide shutters are operated by a handle to open and close the inflow port. something is proposed.
According to this, the above-mentioned problems of the prior art can be solved, but since the operating part of the slide shutter is provided on the front wall of the tank, the operating part of the slide shutter shown in these two publications is There is a problem in that, in addition to specifying the location of the device, especially when installing it in a workplace, the location of the device must also be specified in consideration of the compatibility with other devices.

[Means for solving problems]

The structure of the present invention that solves the problems of the conventional technology is as follows:
A screw transfer body for transferring grains to one side is provided in the valley of a hopper having a rectangular planar shape, and a flow plate having a mountain-shaped end face is disposed over approximately the entire length of the upper part of the screw transfer body. Inflow ports for the grains stored in the hopper to the screw transfer body are formed between both end edges of the plate and the bottom plate of the hopper, and the flow plate is slid into the inflow port portion along the plate surface of the flow plate, and the flow plate is inserted into the inflow port portion. In a grain conveying machine equipped with slide shutters for adjusting the opening and closing of the entrance, one end of an operating rod is provided at the outer ends of both slide shutters, parallel to the plate surface of the slide shutters, and passing through the bottom plate. Connect the other end of this working rod outside the hopper,
They are respectively connected to the outer ends of rotating arms whose midpoints are pivotally supported by bearing plates provided on the external lower side of the bottom plate, and the inner ends of both of the rotating arms are loosely connected to each other, so that the rotation It is characterized in that short tubes into which operating levers can be freely inserted and removed are provided at the outer ends of the arms.

〔Example〕

The details of the embodiments will be explained with reference to the drawings.

Reference numeral 1 denotes a hopper with a rectangular planar shape mounted on a rectangular machine frame 2, and the length of the long side of the hopper 1 is slightly larger than the width of the loading platform of a transport vehicle equipped with a tilting mechanism (dump type). formed over a long period of time. As shown in FIGS. 1 and 3, the hopper 1 is provided with a bottom plate 3 facing upward on the left and right sides along the longitudinal direction, and in the valleys 4 of the bottom plate 3 there are conveying screws arranged along the longitudinal direction of the hopper 1. 5 is installed on a shaft.
7 faces the upper part of the transfer screw 5, and its both ends and the middle part are connected to the side wall of the hopper 1 and the bottom plate 3 by a support member 6, which will be described later.
The flow plate 7 has an end face shaped like a mountain (angular shape with an angle of about 90 degrees), and is attached through the flow plate 7.
It serves to prevent the weight of grains in the hopper 1 from being directly applied to the transfer screw 5, and also forms an inlet 7a for grains between both side edges of the flow plate 7 and the bottom plate 3.

As shown in FIG. 4, the support member 6 is constructed by punching out a metal plate to form substantially right-angled bifurcated legs 6a, and integrally molding the mounting sides 6b on the tops of both legs 6a by bending them at right angles. And this mounting piece 6b
The inner surface of the flow plate 7 is brought into contact with the top of the flow plate 7, and the bolts 6 are attached to both
c, etc., and supports the flow plate 7.
In addition, the outer surface of the leg 6a, more specifically, the mounting piece 6
A cutout step 6d is formed between the lower end of the leg 6a and the inner surface of the flow plate 7 mounted on the mounting piece 6b and the upper surface of the cutout step 6d. The inflow port 7a is formed at the bottom part.
A slide shutter 8 is interposed which has approximately the same length as the flow plate 7 for opening and closing and is slidable along the flow plate 7. One end of a working rod 10 that can pass through the hole 9 provided in the bottom plate 3 is fixed to two places on the left and right middle portions of each of the slide shutters 8, and the other end of the working rod 10,
Specifically, the other ends of the working rods 10 that can protrude outside the hopper 1 are connected to the outer ends of a rotating arm 12 whose midway portions are pivotally supported by bearing plates 11 provided at two locations on the outside lower side of the bottom plate 3. A short tube 13 is fixed to the outer end of the rotating arm 12, and an operating lever 14 is detachably attached to the short tube 13. and,
As shown in FIG. 3, the inner ends of each of the rotating arms 12 facing each other in the front and back are freely connected to each other by a connecting structure consisting of a long hole and a pin. Further, the intermediate portions of the front and rear rotating arms 12 provided on the left and right sides of the hopper are respectively fixed to shafts 15 bridged between the bearing plates 11,
By operating the two operating levers 14 fitted and connected to the short tubes 13, 13 on either the front or rear sides, that is, by rotating from the solid line in Figure 3 to the imaginary line and in the opposite direction. , the left and right slide shutters 8 slide simultaneously and equally, so that the inlet 7a is opened and closed.

In addition, by making the hole 9 provided in the bottom plate 3 through which the working rod 10 passes a blank hole, or by rotatably connecting the working rod 10 to the slide shutter 8, it is possible to When only one of the rotating arms 12 is rotated, the slide shutter 8 is slid diagonally as shown in FIG. 5, and the inlet 7a is gradually narrowed or widened from one end to the other. formed to be
This allows the inflow of grain into the hopper to be adjusted as desired.

In the figure, 16 is a thrower connected to the end of the shaft 5a of the screw transfer body 5, and serves to fry the grains supplied in the thrower 16 to another storage body. Note that what is connected to this screw transfer body 5 may be another fried grain or conveyance device, so it is not limited to the thrower 16. In the figure, 17 is a transmission pulley for driving the screw transporting body 5;
8 is an additional frame installed on machine frame 2 due to an increase in grain storage charges.

〔effect〕

Since the present invention is configured as described above, the following effects can be obtained.

(a) In response to the flow of grains that are about to flow into the screw transport channel through the inlet formed between the mountain-shaped flow plate and the hopper bottom plate, the slide shaft moves along the plate surface of the flow plate. (b) Both slide shutters can be opened and closed more easily and accurately compared to conventional technology. The slide shutter can be opened and closed from either the left or right side of the outside of the hopper, and the slide shutter can be opened or closed from any side depending on the installation conditions of the hopper in the workplace.

(c) Since both slide shutters can be opened and closed from either the left or right side of the outside of the hopper, either the left or right side of the hopper can be installed close to the wall of the workplace, and it is also possible to Compared to the case where the slide shutter opening/closing operation part of the hopper is specified in one place, the installation location can be selected arbitrarily, and the work area can be used effectively.
