Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is mainly used by being mounted on a combine, a harvester, etc., and a grain storage bag inserted and supported by a pair of rotation shafts for suspending and supporting a bag, The screw is formed on the rotary shaft, and is configured to be forced forward with a constant pitch in the axial direction so as to be extended in parallel to the lower part of the grain discharge port, and can be projected below the lower end of the grain discharge port. A movable discharge port can be inserted into the opening of the feeding storage bag in its protruding state, and a full detection sensor is provided on the outer surface of this movable discharge port, and the grain discharge is performed based on the detection result of this full detection sensor. Block the outlet shutter, and
After that, the present invention relates to an automatic bagging device for grains, in which the movable discharge port is housed upward and the sequential operation is performed so as to close the fastener at the bag opening.

[Conventional technology]

Conventionally, in order to provide the full detection sensor on the outer surface of the movable discharge port, it is provided at a substantially central position in the height direction of the movable discharge port (for example, Japanese Utility Model Laid-Open No. 59-107848), and the detection result of the full detection sensor. Based on the above, the subsequent closing of the grain discharge port shutter and the upward operation of the movable discharge port were continuously performed without waiting time.

[Problems to be solved by the invention]

However, based on the insertion depth of the movable discharge port into the bag opening and the positional relationship of the full detection sensor, the grain is filled in the movable discharge port when the full detection sensor senses it.
Therefore, if the shutter is closed and the movable discharge port is actuated upward in this state without time elapses, that portion will not move into the open lateral end of the bag in the open space and will move along the upward movement of the movable discharge port. The swelling occurred and the swelling portion protruded from the opening of the bag, so it was difficult to close the fastener. In particular, since the storage bag is stretched by the rotating shaft, the opening that was forcibly opened by the movable discharge port is reduced by the upward movement of the movable discharge port, and It was supposed to prevent the bag from flowing into the lateral width end side of the opening and promote the rise of the grain.

An object of the present invention is to provide a product that can suppress the rise of grains, can store grains reliably in a bag, and can smoothly perform the fastener closing work.

[Means for solving problems]

The characteristic configuration according to the present invention is that the movable discharge port is operated upward after a lapse of a certain short time after the shutter is closed. The action and effect are as follows.

[Work]

In other words, just by changing the start timing, which leaves a certain short time between the closing of the shutter and the upward operation of the movable discharge port,
Due to the synergistic effect of the flexibility of the shape of the bag itself and the natural vibration of the machine body, the grain located in the movable discharge port is absorbed and stored in the bag within a certain short period of time due to the synergistic effect of the bag. be able to.

〔The invention's effect〕

As a result, by simply changing the control system that delays the start timing of the movable discharge port, you can perform reliable bag filling of grains and smooth closure of fasteners without adding any new mechanism, and automatic bag filling. We have come to be able to provide something that can work more efficiently.

The shutter (7) is configured to be locked and fixed at the open position by the fitting engagement between the protruding piece and the engaging groove (26A). The locking member (26) is biased by a spring (29), and
A check member (27) provided with an engagement protrusion (26B) and an engagement hole (27a) that can be engaged and disengaged is provided so as to be swingable about the longitudinal axis.
Therefore, the engagement protrusion (26B) and the engagement hole (27a) are fitted and engaged with each other to prevent and prevent the shift of the locking member (26) in the unlocking direction. Further, a swinging operation member (24) that is operated in one direction in the restraint releasing direction is provided to the restraint member (27), and accordingly, a locking arm (18) continuously provided to the chain (19). By the contacting operation of the swing operation member (24), the swing operation member (24) acts on the restraint member (27) only when the swing operation member is rotated in the restraint release direction.
Since the rocking operation member (24) is biased by the spring (28) so as to be returned to the neutral position, the engagement member (1
The contact portion with 8) is configured to return to the movement locus of the engaging member (18).

After the first arm (16) presses and passes the lifting operation lever (5a), the lifting operation lever (5a) is moved to the vicinity of the pivot point of the lifting operation lever (5a) with respect to the movable discharge port (5A). An inverted C-shaped plate spring is provided as a restoring mechanism for returning to the movement locus of one arm (16), and the elevating operation lever (5
It is configured so that a) is brought back to work. Further, an operation arm (40) is provided which is directly connected to the movable discharge port (5A) and transmits the operation of the elevating operation lever (5a) to the movable discharge port (5A). At the connecting portion with the lifting operation lever (5a), the protruding piece (5b) is on the lifting operation lever (5a) side and the protruding piece (5b) is on the operation arm (40) side.
And an engaging groove (40A) which can be fitted and engaged with the engaging member (40A) so as to be interlockingly connected to each other.
A) is formed large in a state where there is a gap in the fitted state of both (5b) and (40A), and this gap part is made up of the lifting operation lever (5
It is configured to function as an accommodation (41) corresponding to the restoration stroke of a).

Therefore, when the plate spring (39) of the raising / lowering operation lever (5a) pressed and swung by the first arm (16) is used to return to the movement locus of the first arm (16), the raising / lowering is performed. Due to the interchange (41) between the operation lever (5a) and the operation arm (40), the movable discharge port (5A) can be returned without simultaneous operation.
