Description

[Detailed description of the invention] [Industrial application field] Misfire F! A#'i, used by being mounted on a combine harvester, etc. #i The upper end opening of the grain storage bag has a movable discharge port that moves up and down relative to the grain discharge provided above the grain storage bag. At the same time, the grain is filled into the general goods bag by opening the shutter provided at the grain discharge port, and the filled grain is placed near the lower end of the movable discharge port (b). The present invention relates to a bag filling device that is configured to close a sealer based on a sensor that detects that the bag is filled to the vicinity of the lower end of the bag, and to move a movable discharge port upwardly.

[Conventional technology]

Conventionally, in this type of bagging device, the shutter is opened based on the sensor's sensing of the filled grains (i.e., full detection), and the movable discharge port is raised and retracted immediately after the shutter is closed. (Jitsukai 59-17
Publication No. 0484).

[Problem that the invention seeks to solve]

However, as shown in FIG. 1(a), the movable discharge port (11
) is inserted into the upper end opening (4A) of the grain storage bag (4), the shutter (9) is located above the sensor body at a certain distance, so the mtJ period sensor body detects the grain. Even if the shutter was closed in this state, the grain would still be stored above the grain rope. Therefore, after the shutter (9) is closed, the pre-discharge port (1
When the sensor (1) is raised without any time elapsed, the sensor (3)
), the grains located above the upper end opening (4A) of the grain storage bag (4) bulge outward and upward, so that they do not leak out from the upper end opening (4A). there were.

An object of the present invention is to provide a grain storage bag which can suppress leakage of grain from the upper end opening by providing a rational grain absence confirmation mechanism.

[Means for solving problems]

The characteristic configuration according to the present invention is to close the shutter based on the detection by the sensor, detect that there is no grain from the vicinity of the nE sensor, and raise the movable discharge port based on this grain absence confirmation information. The i5J function is structured as follows, and its functions and effects are as follows.

[For production]

After a certain period of time has elapsed, the grains stored above the sensor after the pick and shutter are closed will become clear. Due to the synergistic effect of being made of deformable cloth, it is recognized that the grains will be stored in the free space due to the influence of aircraft vibration, etc. Once the grains have been detected by the sensor, the grains will be removed after a certain period of time. The absence of aiiWg
Then, it can be determined that the filled grain located above the sensor is filled into the grain storage bag, and even if the movable discharge port is raised and retracted thereafter, leakage of grain from the upper end opening of the grain storage bag is suppressed. be able to.

〔Effect of the invention〕

As a result, by operating the movable discharge port in a state where the absence of grain is detected in the pod, it is possible to not only suppress the leakage of grain, but also to achieve a high level of perfection as a device that adopts the sequence control method. In detail the automatic bag packing device as one of the bag packed devices mounted on combine, which has led to the provision of things.

First, the bag feeding mechanism (1) will be described. As shown in FIGS. 8 and 4, a pair of left and right rotation axes +2+,
+2), the grain storage bag (4) with eyelets (31, t3+ formed near both ends of the upper end opening * (4A)) is attached to the eyelet (3).

(3) Suspended and supported through the rotating shaft (2)
.

Threaded part formed at the tip of (2) +61, +51 screw groove (5A), (5A) and eyelet 131, fall
By the fitting engagement of the drive motor [61
, 16), the grain storage bag (4) is fed out in the direction of the rotating shaft axis, and the feeding is stopped at a predetermined grain discharge position.Next, the bag filling device (7) will be described in detail. . Above the grain storage bag (4) stopped at a predetermined position, there is a grain storage hopper (8), and a shutter (9) is installed at the lower end of the grain storage hopper (8).
- Equipped with a grain outlet 11 (11).

This grain discharge port 11O) is provided with a movable discharge port (11) that can be inserted into the grain storage bag (4) and that can be moved up and down.
A pair of left and right rocking-assisted opening/closing bag openings (02) and 0.0 turbidity are provided on both end faces of the grain discharge port (10), and a bag opening device (11) is provided in conjunction with the lowering operation of the movable discharge port (1). Insert the odor into the bag opening and then lower the movable outlet (1) until the bag opening 5 (4A) is large enough to insert the movable outlet (11).
) is configured to have a t-oscillation function. A chain mechanism DI that circulates approximately horizontally above the grain storage bag (4) is provided near the grain discharge port (λU), and this chain mechanism DI is connected to the shutter (9) and the movable discharge port (l). and grain storage bags (
4) The operating member for the fastener circle provided at the upper end opening is attached so that it can be operated integrally. These operating members 09) act on a first actuating arm which acts on a first arm 06) which is interlockingly connected to the shutter (9), and a bell crank shaped second arm end which is interlockingly connected to a movable discharge port (11). and a retaining arm H that engages with the slider 07 provided on the zipper (I4) and moves it in the zipper closing direction. Next, with reference to FIG. 8, a series of operations by the chain mechanism (l■ operation) will be explained. Upon sensing this, the chain mechanism 03) starts operating. First, as shown by the arrow in the figure, the operating member moves the movable outlet (11) downward and opens the shutter (9) to perform the grain filling operation. ) is installed near the lower end of the movable discharge port (the movable discharge port). Stop once.

Then, as shown in FIG. 1(b), when the sensor no longer detects the presence of grain after detecting the grain, the grain located above the sensor wire is filled into the grain storage bag (4). It is determined that the movable discharge port (11)
It operates to raise and retract the zipper and subsequently close the zipper.

[Another example]

In the above configuration, the sensor is also used as a mechanism for detecting the absence of grain from the vicinity of the sensor (2)), but a mechanism for detecting this is separate from the Ifl period sensor (2)). It may be provided.
