Description

[Detailed description of the invention] The present invention relates to a grain conveying device.

Conventionally, this type of grain conveying device is equipped with a large number of small air suction holes on the side of the grain lifting drum opposite to the side where the grain is introduced, and this is particularly useful in combine harvester operations, etc., to remove straw and dust flying into the air. This air suction hole is blocked by the drying process, and the amount of outside air taken into the grain-lifting drum is drastically reduced, resulting in a significant drop in grain-lifting capacity and, in many cases, eventually becoming impossible. Workers had to constantly monitor it.

The present invention was developed in view of the above circumstances, and has a simple structure and rational means, that is, a hopper having a relatively large air introduction window is provided on the side of the grain lifting drum opposite to the grain introduction side. By doing so, the drawbacks of the conventional method are completely eliminated, and the scattered grains can be supplied to the grain lifting machine from the hopper as well.
It is an object of the present invention to provide a grain frying device with a large grain transfer processing capacity.

To explain the details of the embodiment with reference to the drawings, A is the combine main body, B is the reaping part, C is the threshing device,
D is a grain collecting device. 1 in threshing device C
2 is a handling cylinder, 3 is a swinging sorting body, and 4 is a screw conveyor for conveying the threshed grains to one side. Reference numeral 5 in the grain collecting device D is a screw raising body for upwardly conveying the grains conveyed to one side by the screw conveying body 4 into the grain tank 6.

7 is a screw transfer body installed at the deepest part of the hopper-shaped bottom plate of the grain tank 6;
The function is to send the grains inside to a grain lifting machine, which will be described later.

F is a flip-up grain lifter attached to the outer surface of the grain tank 6, and the grain lifter F is provided with flip-up wings 8 at the delivery end of the screw transfer body 7;
This is located inside a grain lifting drum 9, and a grain lifting cylinder 10 is provided in the centrifugal direction of the grain lifting drum 9. The middle part of the grain lifting cylinder 10 is fixedly and releasably attached to an arc-shaped guide member 11 provided on the side wall of the grain tank 6, and by moving the position of this, the grain lifting cylinder 9
rotates with respect to the grain tank 6, specifically, the angle of the grain lifting cylinder 10 is displaced in the direction of the arrow, and the tightening nut 11
a so that it can be fixed at a predetermined angle.
Further, the upper bent portion 10a of the grain frying cylinder 10 is rotatable, so that the direction of grain frying can be arbitrarily selected.

A separation part is provided in the middle of the grain lifting cylinder 10, more specifically, at a position slightly higher than the upper surface of the grain tank 6 when the grain lifting cylinder 10 is vertical. Formed fried grain cylinder 10b
and flanges 12 and 13 provided at the ends of the grain barrel 10.
One ends are hinged to each other, and a connecting tool 14 between the flanges having a cam structure is attached to the portion of the one flange 12 corresponding to the hinged portion, so that the middle portion of the grain lifting cylinder 10 is connected to the flange 12, It is made so that it can be bent approximately 90 degrees from the 13th part.

An upward holding member 15 for holding the bent grain lifting cylinder 10b horizontally on the combine main body A is provided on the upper part of the threshing device C. As shown in FIG. 1, the horizontally folded grain lifting cylinder 10b is provided with a separation part having the same structure as above, that is, a flange 16, 17, Connector 1
8, so that the grain lifting cylinder 10b is further folded onto the combine main body A as shown in the figure, and this bent grain lifting cylinder 10c is also supported on the holding member 15. .

Further, as shown in FIG. 3, a large air introduction window 19 is formed on the outer surface of the grain lifting drum 9 constituting the flip-up grain lifting machine F, and a large air introduction window 19 is formed on the outer surface of the grain lifting drum 9 so as to cover this. A hopper 20 is rotatably attached to the outer surface. The freedom of rotation of the hopper 20 is restricted by friction, and is prevented from moving freely due to mere mechanical vibration or the like.

That is, the opening of this hopper 20
Although the hopper 20 can be positioned in any direction relative to the hopper 20, the opening of the hopper 20 can always be corrected and held upward no matter what angle the grain lifting cylinder 10 is displaced. The purpose is to Reference numeral 21 denotes a safety plate provided to prevent human hands from touching the flip-up wing 8.

Since the present invention is configured as described above, the air introduction window is not blocked by straw waste etc. as in the conventional case, and therefore, the present invention has the advantage that highly efficient grain frying work can be carried out stably at all times. Furthermore, by putting grains that are scattered onto the body of a combine harvester, straw waste, and other grains that are scattered into the hopper, these grains can be lifted up and transported together with the introduced grains. By making this hopper rotatable relative to the grain lifting drum, when the grain lifting drum is rotated to change the grain lifting direction or angle, only the hopper can be rotated independently and the opening of the grain lifting cylinder can be changed. It has excellent features such as being able to always point upward.
