Description

[Detailed Description of the Invention] [Industrial field of application] The present invention allows a pair of support bars extending in a cantilevered manner to support a collection bag so that the collection bag can be inserted and removed freely, and the grain flows down to the collection bag. A sensor for detecting that the grain is filled up to that position is provided on the inner surface of the middle position of the guiding discharge cylinder, and the passage of the discharge cylinder is automatically provided above the sensor according to the detection of the grain filling of the sensor. The present invention relates to a grain bag packing recovery device provided with a shutter for blocking.

[Conventional technology]

In the above-mentioned conventional recovery device, for example,
As shown in the publication, the discharge cylinder is configured to deeply enter the inside of the collection bag so that the collection bag does not come off due to strong wind or the like. Also, the discharge cylinder is vertically long to accommodate the sensor.

[Problems to be solved by the invention] However, in the above-mentioned conventional structure, the collecting bag is filled with grain culms,
When the bag is removed from the support rod, the grain fills up to the sensor-existing portion, that is, almost the entire discharge cylinder. Therefore, the operator shakes the bag because the residual grain in the discharge cylinder flows into the bag. However, due to the large residual amount, some grain culms may remain in the discharge cylinder. Therefore, when the bag is pulled out, the residual grains may be scattered outward and may be lost. Further, since the discharge cylinder is deeply inserted into the bag, there is a drawback that it takes time to push down the upper portion of the bag when the bag is removed and avoid the discharge cylinder.

It is an object of the present invention to suppress the scattering loss of the residual grains in the discharge cylinder and to facilitate the extraction work of the recovery bag.

[Means for solving problems]

A feature of the present invention is that, in the grain bag packing recovery device having the above-described configuration, the lower side of the discharge cylinder below the sensor is composed of left and right divided movable cylinder units, and both movable cylinder units are It is provided so as to be swingable and displaceable toward the inner side of the cylinder around the upper horizontal axis, and is configured to block the passage due to the swing displacement. Is.

[Action]

When the collection bag is filled with grains and the grain is filled up to the portion where the sensor is present, the shutter is shut off. Then, the movable cylinder unit bodies are respectively oscillated and displaced inwardly around the shaft center to block the discharge cylinder passage, thereby preventing the residual grains in the discharge cylinder from scattering, and Since the core is provided at the upper part, both movable cylinder units swing upward and are located above the recovery bag, so that the removal work can be facilitated without disturbing the removal of the bag.

[Effect of device]

Therefore, the grains remaining in the discharge cylinder will not be scattered outside when the collection bag is removed, and the grain loss can be suppressed as much as possible. There is no need to avoid pressing down significantly, and work efficiency has improved dramatically.

〔Example〕

Fig. 4 shows a combine equipped with a grain bag packing recovery device (A) according to the present invention. Bag-catch recovery device (A)
Is installed on the lateral side of the threshing device (1), and the grains threshed by the threshing device (1) are lifted by the vertical screw conveyor (2) toward the inside of the hopper (3) above the recovery device (A). It is configured to be transported and is configured to store grains in the hopper (3). Below the hopper (3), the threshing device (1)
The collection bag (5) is supported in an upright position by a pair of support rods (4), (4) extending in a cantilever manner from the side so as to be freely detachable.

Then, a discharge cylinder (7) is provided at a lower part of the hopper (3) so as to extend downward, and the discharge cylinder (7) is inserted so as to be deeply inserted into the recovery bag (5), and the hopper (3) Discharging cylinder inside (7)
It is configured so as to be guided downward into the collection bag (5) through the passage (S) therein. Further, as shown in FIG. 3, a pressure-sensitive sensor (8) for detecting that the grain is filled up to that position is provided on the inner surface of the middle of the discharge cylinder (7). A shutter (9) that automatically shuts off the passage (S) of the discharge cylinder (7) in response to the detection of the filling of the grain culm by the sensor (8) is provided above.

This shutter (9) has a compression spring, as shown in FIG.
The shutter (9) is urged by the (10) in the closing direction, and the end grip (11) is pulled against the urging force of the spring (10).
Is configured to be opened, and the projecting piece (12) provided on the side opposite to the grip (11) and the locking piece (13) are engaged to hold the open state. And the sensor (8)
When the grain filling is detected, the solenoid (14) is actuated, the swing locking piece (15) swings, and the protruding piece (12) and the locking piece (1
The engagement state with 3) is released, and the shutter (9) is automatically closed accordingly.

As shown in FIG. 1, the lower side of the sensor (8) of the discharge cylinder (7) is composed of movable cylinder units (7a), (7b) divided into left and right, and both movable cylinder units ( Each of 7a) and (7b) is swingably displaced around the upper horizontal axis (P ₁ ) and (P ₂ ) toward the inner side of the cylinder. That is, both movable cylinder unit bodies (7a), (7b)
At the lower end of the upper fixed cylinder portion (7c) of the discharge cylinder (7), the shaft core (P ₁ ),
(P ₂ ) Pivot around rotatably and
