Description

[Detailed Description of the Invention] The present invention relates to an improvement of a rice bag support device in a combine harvester.

The conventional rice bag support device (hanger) in a combine harvester is usually located above the rice holder and on both sides of the paddy outlet of the hopper and is fixed to the machine body, and the distance between the rice holder and the hanger is generally It is set to be smaller than the paddy bag length in . This is done by sharing the load with the paddy holder when the bag is full, and taking into consideration the horizontal bulge of the bag due to filling with paddy.
This is also to facilitate the removal of a full bag. However, with this type of structure, when the paddy bag is set on a hanger, the bottom of the bag may come into contact with the paddy holder and bend, preventing the paddy from entering that part. Not only is it not possible to keep the paddy bag full all the time, but when changing the paddy bag, the elastic gutter installed at the paddy outlet of the hopper to prevent paddy from scattering gets in the way, making it difficult to attach and remove the paddy bag, resulting in poor work efficiency. Each time the paddy bag is attached or removed, the opening of the bag comes into contact with the gutter and the gutter is forcibly deformed, resulting in inconveniences such as significant damage to the part.

The present invention was developed to solve the above-mentioned problems all at once.The purpose of this invention is to immerse the gutter into the paddy bag to store the grains. In the rice bag support device, which is attached to the rice bag so as to be vertically displaceable, a stopper is provided to position and hold the hanger at an upper position where the bottom part of the rice bag suspended from the hanger separates from the rice holder, and the rice bag is full of grains. When the paddy bag is almost filled, the stopper senses the weight of the grains and automatically releases the fastening, displacing the hanger to the lower position where the full paddy bag is supported by the paddy holder, and removing the tip of the gutter from the paddy bag. By making the paddy bag protrude to the outside and retaining it in a downward position even after removing a full paddy bag, the paddy bag is initially suspended in the air away from the paddy holder, and the gutter is immersed inside the bag. At least you can set it on a hanger,
In addition to being able to always fill the paddy to the full, the hanger can be automatically moved downwards when the paddy is full, allowing the bag to be replaced while the full bag is supported on the paddy holder, and the bag opening is not far from the gutter. Not only can this be done easily with the paddy bag pulled out, but it is also easy to attach an empty paddy bag after removing a full paddy bag, further increasing work efficiency and preventing damage to the gutter. The purpose of the present invention is to provide a rice bag support device for a combine harvester.

To explain the structure of the present invention with reference to an embodiment shown in the drawings, 1 is a hopper for storing paddy mounted on a combine harvester, and a paddy outlet 2 provided at the lower part of the hopper is equipped with a flexible member such as rubber. A cylindrical gutter 3 consisting of
is installed. Reference numeral 4 denotes a paddy receiving stand provided below the paddy outlet 2, and 5 indicates a hanger for suspending paddy bags, which are provided in pairs on both sides of the paddy outlet 2 of the hopper 1 in the direction of movement of the machine.

FIG. 2 shows the mounting structure of the hanger 5, in which the hanger 5 is attached to the stay 6 which is erected and fixed on the fuselage side.
A collar 7 with a hanger 5 fixed to one side is fitted so as to be slidable up and down, and the bottom of the collar 7 has a spring receiving hole 7' which communicates with the spring receiving hole 7' as it goes downward. A tapered hole 7'' that gradually expands is provided.

A movable piece 8 is located below the collar 7 and is slidably fitted to the stay 6. A spring receiving hole 8' corresponding to the spring receiving hole 7' on the collar side is provided in the upper part, and the piece is movable. The lower part of piece 8 is formed into an upside-down truncated cone shape. A pair of brackets 9, 9a are fixed to the outer periphery of the movable piece 8, and the brackets 9, 9a have stoppers 10, 1 whose upper end slopes a face directly below the tapered hole 7'' of the collar 7.
0a is swingably mounted via a fulcrum pin 11, and at the lower end of the stopper 10, 10a, a locking portion 10' that removably engages with a groove 12 provided at a predetermined portion of the stay 6, respectively. , 10'a are provided. These stoppers 10, 10a are connected to the lower end locking portion 1 by means of a return spring 11a interposed in the pivot portion.
0' and 10'a are always biased toward the stay 6 side. Reference numeral 13 denotes a compression coil spring, one end of which is fixed to the spring receiving hole 7' on the collar side and the other end fixed to the spring receiving hole 8' on the movable piece side with spring retaining bolts 14 and 15, respectively, so that the collar 7 and the movable piece 8 are They are connected via a compression coil spring 13.

In the figure, 16 is a stepped portion located below the groove 12 and provided on the stay 6, and 17 is a paddy bag.

In the lyrical structure, at the beginning of paddy bagging work, that is, when there is no paddy in the paddy bag 17 yet, the lower end locking portion 1 of the stopper 10, 10a
0' and 10'a are respectively fitted and locked in the grooves 12 of the stay 6 as shown in FIG. In this case, the paddy bag 17 suspended from the hanger 5 is positioned and held at an upper position where the bottom part 17' is separated from the paddy holder 4 and the gutter 3 is recessed into the bag's upper end opening 17''. In this state, When a shutter (not shown) attached to the paddy outlet 2 of the hopper 1 is opened, the paddy in the hopper 1 is sequentially dropped and stored in the paddy bag 17.
The paddy bag 17 is supported by the hanger 5 in a suspended state as described above, and the bag bottom 17' is
There is no possibility that the paddy will be bent on the paddy tray 4 while it is empty, so the paddy will be filled to every corner of the bag 17, and the paddy will not scatter to the outside from the bag opening 17''. do not have.

When the paddy bag 17 is almost full,
The weight of the paddy overcomes the elastic force of the spring 13, and the collar 7 and the hanger 5 are horizontally displaced downward together with the full paddy bag 17. When the inclined surface of the tapered hole 7'' provided in the collar 7 comes into contact with the upper end inclined part a of the stopper 10, 10a, the stopper 10, 10a
is rotated about the pivot pin 11 against the return spring 11a in the direction of releasing the fastening of the stopper.
Therefore, the movable piece 8 further descends on the stay 6 and stops with its lower end abutting the stepped portion 16 (see FIG. 4). At this time, the collar 7, hanger 5, and paddy bag 17 also descend at the same time, so when the movable piece 8 comes into contact with the step and stops, the paddy bag 17 is placed on the paddy tray 4 as shown by the solid line in FIG. The paddy bag 17 is directly supported and the weight of the paddy is received by the paddy holder 4, and the paddy bag opening 17'' is completely pulled out from the gutter 3, so the full paddy bag 17 can be carried without being disturbed by the gutter 3 , hanger 5
It can be easily removed from the When the full paddy bag 17 is completely removed, the collar 7 and the hanger 5 are attached to the fourth
As shown in the imaginary line in the figure, although the movable piece 8 is lifted upward by the amount of deflection of the compression coil spring 13, since the movable piece 8 is still at the lowest position, the collar 7 and the hanger 5
is located below the initial paddy bag setting position (the position shown in Figure 2). Therefore, when attaching the empty paddy bag 17 to the hanger 5 again, it is necessary to
It does not interfere with the work by hitting the bag opening 17'' and can be easily attached.

After the bag 17 is attached, if you hold the hanger 5 in your hand and pull it upward, the collar 7 and the movable piece 8 are connected by the compression coil spring 13, so the collar 7, the movable piece 8, and the stopper 10, 10a are connected. is also pulled up at the same time, and the locking portion 1 of the stopper 10, 10a
0' and 10'a are fitted into the grooves 12 again and retained in the initial set position shown in FIG.

In this embodiment, a case has been described in which the paddy bag opening 17'' is completely pulled out from the gutter 3 when the hanger 5 is lowered, but the lower ends of the paddy bag 17 and the gutter 3 are generally flexible. It is made of materials,
When replacing the paddy bag 17 (when the hanger 5 is lowered), remove the paddy bag 1.
Since the upper edge 7 and the lower end of the gutter 3 are bent, even if the gutter 3 is configured to face shallowly into the paddy bag opening 17'', there is no problem in the bag exchange operation, and this does not deviate from the present invention.

As mentioned above, the present invention is a paddy bag support device in which a hanger for suspending a paddy bag, which stores grains by inserting a gutter into the paddy bag, is mounted in a horizontal position above a paddy holder so that it can be vertically displaced. A stopper is provided to position and hold the hanger at an upper position where the bottom part of the paddy bag suspended from the hanger separates from the paddy receiver, and when the paddy bag is almost full of grains, the stopper stops the grains from being removed. The weight is sensed and the fastening is automatically released, and the hanger is moved to a lower position where the full paddy bag is supported by the paddy holder, so that the gutter tip protrudes from the paddy bag to the outside, and the full paddy bag is removed. Since the structure is configured to hold the bag in the lower position even after it is removed, it reliably prevents the inconvenience of the bottom of the paddy bag bending on the paddy holder, which is the case with conventional fixed hangers. It is possible to always fill every corner of the paddy bag to the full, and when the paddy bag is full, the hanger can be automatically displaced and held downward by the weight of the grains, making it easy to replace the paddy bag when replacing the paddy bag. The work of attaching and removing the bag can be done extremely easily without any interference from the gutter, which not only greatly improves work efficiency, but also prevents inconveniences such as deformation or damage of the gutter when replacing the paddy bag. This has the effect of eliminating the problem.
