Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a bag feeding mechanism that feeds a grain bag in a suspended state from a grain outlet, and a bag feeding mechanism that feeds a grain bag in a suspended state from a grain outlet, and a bag feeding mechanism that sends grain bags from the outlet to the grain bag. Regarding the bag support structure of a grain bagging device equipped with a deck that supports the grain bag in a loaded state when being supplied, in detail,
Concerning techniques for stuffing as much grain gold as possible into grain bags.

[Prior Art] Conventionally, as a grain bagging device configured as described above,
For example, there is a grain bagging device disclosed in Japanese Patent Application Laid-Open No. 60-34111, in which a large number of grain bags are stored in a suspended state on a pair of bag support rods, and these grain bags are After one of the grains is sent out against the support rod and positioned below the grain outlet, the grains are fed into the grain bag, and when the grains are fed in this way, In this case, the lower end of the grain bag contacts the deck so that the weight of the grain bag is not added to the support rod.

[Problems to be Solved by the Invention] However, in a structure in which the lower end of the grain bag contacts the deck as in the above-mentioned example, the support rod (4) overflows as shown in FIG. 6(a). When the grain bag (6) is sent out, the lower end (60) of the grain bag is often bent between it and the deck (5), and in this bent state, the grains are bag(
6) When the grains (G) are supplied, the grains (G) are not fed into the bent part as shown in Figure 6 (b).
In some cases, it may not be possible to pack a predetermined amount of grain into the grain bag (6).

The purpose of the present invention is to rationally modify the grain bagging device in which the grain bags are sent in a suspended state as described above, and to simplify the structure of the bag support structure that can stuff as much grain gold as possible into the grain bags. The point is to compose it.

Means for Solving Problem E] The feature of the present invention is that in the grain bagging device having the above configuration, the grain bag is filled until a predetermined amount of grain from the discharge port is supplied to the grain bag. The lower part of the grain bag is locked and held on the upper side in the feeding direction of the bag feeding mechanism, and when the sweetness of the grains reaches the predetermined amount, the locking retainer of the lower part of the grain bag is released by the grain bag's own weight. The bag locking member is provided, and its functions and effects are as follows.

[Function] If the above-mentioned characteristic sound is configured as shown in Fig. 5, the grain bag (6
) is sent below the discharge port (3), the lower part (6b) of the grain bag (6) comes into contact with the bag locking member αη, as shown in FIG. The grain bag (6) is held on the upper side in the bag feeding direction, and then when grains (Gl) are supplied to the grain bag (6) and the weight of the grain bag (6) increases, the grain bag (6) is held by this weight. is released, and at the same time as this release, the grains (G) in the bag enter the bottom (6b) of the grain bag (6), and then the grain bag (6) is supported by the deck (5). It becomes.

[Effects of the Invention] Therefore, by a relatively simple modification of providing a bag locking member, the grain bag can be supplied with grains while being supported by the deck. A support structure capable of feeding many grains was easily constructed.

〔Example] Embodiments of the present invention will be described below based on the drawings.

As shown in Fig. 2, a slide-operated shutter (2) is provided at the bottom of a hopper (1) for storing grains, and a discharge port (3) consisting of a cylinder that can move up and down.
As an example of a bag feeding mechanism, a support rod (4) formed with a spiral body (4a) is provided on both sides of the discharge port (3), a deck (5) is provided below these, and a deck (5) is provided below the support rod (4).
2), discharge port (3), and support rod (4).

(4) The entire grain bagging apparatus is configured by providing a mechanism for operating the above.

This grain bagging device is mainly used in a combine harvester with a structure in which grains are continuously fed into a hopper.
) is configured so that the operation until it is released is performed automatically.

That is, as shown in FIGS. 3 and 4, the shutter (
2) is urged in the closing direction by a spring (7) and connected to one swinging arm (8), and an arm (9) for opening and closing operation is attached to the discharge port (3), Further, the support rod (4) (4) is configured to be rotated by electric motors QQ and C1 (l).

A zipper αυ is provided at the bag opening (6) of the grain bag (6), and eyelets (
6) and (b) are provided, and before starting bagging of grains, these grain bags (6) and 11t-support rods (4) I (4)
It is designed to hang and hold.

During the bagging operation, one of the grain bags (6J... , the discharge port (3) is made to protrude downward, and the shutter (2) is operated to open, and then when the grain bag (6) is full of grains (G), the shutter (2) is closed; Then, the discharge port (3) is fully raised upwards, the holder K and the fastener Qυ are closed, and finally, the grain bag (6) is completely discharged by rotating the support rod (4).

In addition, among the above-mentioned operations, the shutter (2) and the discharge port (3)
, 7 aseners αη are operated by driving an endless chain.

An operating arm C14) is provided in a cantilevered manner on the end of the endless chain, and a first pin α9 extends substantially horizontally to the operating arm Q4, and a second pin α9 extends substantially vertically to the operating arm Q4.
A pin CIG is provided, and the first pin α9 is connected to the arm (9
) By touching the rose, the discharge port (3) can be fully opened and retreated, and
The shutter (27) is opened by the second pin qQ contacting and suppressing the swing arm (8), and the tip (14&) of the operating arm α4 comes into contact with the slider (11&) of the fastener Q. By touching the zipper, the zipper is closed.

Incidentally, there is no operating arm 0 within the operating trajectory of operating arm α4.
A sensor (81) for detecting the operation of the turret.

(82) and (83) are provided, and these sensors (SR)
, (82).

(S3) and a sensor (not shown) that detects that the grain bag (6) is full of grains (Gl), and that the grain bag (6) has been sent below the discharge port (3). A sensor that detects (
(not shown) etc., the endless chain (to)
, a control system is configured to operate electric motor αQ.

As shown in FIG. 2, for the grain bags (6) suspended and supported by the support rods (4) + (4), there is a bag locking member made of a rod on the lower side in the bag feeding direction. αη is provided so as to contact the lower part of the grain bag (6) to be sent out, and the first
As shown in FIG. As the weight of the grain G) increases when it is supplied to the grain bag, the lower part of the grain falls off and folds into the bottom part (6b) of the grain bag (6), as shown in Figure 1 (B). It is arranged so that it can be placed on the deck (5) without any trouble.

As shown in FIG. 5, an auxiliary deck (G) with a low step is formed on the outside of the deck (5), and
A pallet M is provided that is movable in the longitudinal direction of the vehicle body, and the grain bags (6) have been filled with grains (G) as described above and have been sent out from the support rods (4) + (4). However, it can be placed in two tiers, top and bottom.

(Another Embodiment) In addition to the above-mentioned embodiments, the present invention includes, for example, a bag locking member that is entirely composed of a pair of left and right spring plates, and the spring plates are elastically deformed as the weight of the grain bag increases due to grain supply. In addition, the structure may be such that the lower part of the grain bag is released from being held.
