Description

[Detailed description of the invention] The present invention consists of installing a bracket and a locking tool on the side of the aircraft body at an appropriate distance in the longitudinal direction of the aircraft body, and using these brackets and the locking tool to form a rod-shaped member that is long in the longitudinal direction. The front part of this rod-shaped member and the front end of a boat for receiving and collecting harvested crops are connected via a fitting having two pivot shafts, a horizontal axis and a front-rear axis. The present invention relates to a crop collecting device for a reaping harvester, which is configured to be rotatable around the axis of the horizontal axis and the axis of the longitudinal axis.

As a conventional technique, the present applicant first submitted it (Showa
There is a technique in Jitsugan No. 1983-4348 (January 17, 1953). This prior art crop collecting device for a reaping harvester can collect harvested crops one by one on a boat, so it can be used particularly conveniently when working in wet fields. Since it can pitch and roll, it is excellent in that it can avoid the attitude of the aircraft being disturbed by the boat trying to be displaced due to unevenness in the field. To be more specific, as a means of allowing the boat to pitch and roll with respect to the aircraft, it has been considered to simply tow the boat with a chain, etc., but in this case, the towing resistance changes due to the meandering of the boat. death,
Compared to the drawback that the straightness of the aircraft is likely to be impaired, the above-mentioned patent application allows the boat to rotate only around two axes, resulting in deterioration of the straightness due to such meandering of the boat. It is excellent in that it does not cause any problems and can further improve maneuverability.

The purpose of this invention is to further improve the stability of the machine's attitude by adding technical improvements to the conventional reaping and harvesting machines described above. In this case, the front end of the boat was fixed at a fixed position in the vertical direction relative to the aircraft body, so the entire boat and the aircraft body could not be vertically displaced relative to each other, and this prevented the aircraft's attitude from being disturbed by the ground reaction force acting on the boat. The problem is that the effect was not sufficient.

The technical means of the present invention taken to solve the problem is to install a bracket and a locking tool on the side of the aircraft at an appropriate distance in the longitudinal direction of the aircraft.
These brackets and locking devices support a rod-shaped member that is long in the front-rear direction, and the front part of this rod-shaped member and the front end of the boat that receives and collects the harvested crops are connected to two pivot axes, a horizontal axis and a front-rear axis. In a crop collecting device for a reaping harvester, the boat is configured to be rotatable around the axis of the horizontal axis and the axis of the front and rear axes by connecting the boat via a fitting with A long hole in the vertical direction is formed in the bracket attached to the side of the fuselage on the forward side of the fuselage, and the rod-shaped member is inserted through the elongated hole so that the bracket supports the rod-shaped member so as to be freely vertically movable. This has the following effects and effects.

That is, according to the technical means of the present invention, when a vertical force acts on the boat due to a ground reaction force, the rod-shaped member, that is, the pivot shaft itself moves up and down via the pivot shaft connecting the boat. This acts to allow not only the vertical movement of the rear end of the boat about the lateral axis, but also the vertical movement of the front end of the boat, which is the part that first runs aground on a convex part of the field.
Therefore, while maintaining the ability to prevent the boat from rolling sideways and maintain the straightness of the aircraft, this function prevents the entire boat from moving up and down freely relative to the aircraft, and from pitching and rolling the boat relative to the frame. By working together, it became possible to reliably avoid the aircraft's attitude being disturbed by the ground reaction force acting on the boat.

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

Figures 1 and 2 show side and plan views of the reaping and harvesting machine. As will be described later, there is provided a harvesting section collection device equipped with a collection boat 5 for receiving and collecting harvested crops that are successively supplied.

The reaping binding unit 1 includes a device 6 for raising the stem culm to be planted into an upright position, a reaping device 7 for cutting the base of the raised stem culm, and a conveyor cover 8 to collect the cut stem culms that are sequentially supplied along the conveyance cover 8. It is composed of a binding device 9 and the like that performs the binding process.

As shown in FIG. 3, the bundling device 9 receives the cut stem culms that are successively raked by the raking packer 10 with a door 11 that rotates intermittently at 180 degrees, and collects them in an appropriate amount. , when a suitable amount of bundles have been collected, the string supply needle 12 or the like is operated to bind the bundled stalk culms, and then the bundled stalk culms are attached to the door 11.
The device is configured to be pressed and released onto the recovery boat 5 by the operation of .

On the body side, as a mounting frame for the boat 5, there is provided a rod-like member 14 extending in the front-rear direction and inserted and supported by a bracket 13 connected to the binding device 9 so as to be movable in the front-rear direction. The front end of the recovery boat 5 is
This rod-shaped member 14 has a horizontal shaft 19 formed by an end portion of the rod-shaped member 14 extending outward from the side of the fuselage.
a and a front-rear shaft 19b disposed orthogonal to the horizontal axis 19a, the rear end side of the boat 5 is connected to the It is configured to be swingable around the axis X ₁ of the horizontal shaft 19a and the axis X ₂ of the longitudinal axis 19b, and is configured to be freely movable in the longitudinal direction with respect to the body, and the rod-shaped Member 14
is configured to be automatically displaced rearward with respect to the fuselage due to ground resistance when it is switched from a state in which it is locked and held by a locking tool 15, which will be described later, to a state in which it is released. Further, an insertion hole for the rod-shaped member 14 formed in the bracket 13 attached at a position on the side of the fuselage on the front side of the fuselage than the locking tool 15,
As shown in FIG. 5, an elongated hole 18 is formed in the vertical direction, and the rod-shaped member 14 is configured to be freely movable up and down about the locking portion of the locking tool 15.

As shown in FIG. 4, the locking tool 15 is rotatably supported on the binding device 9 about the vertical axis Y, and is configured to swing back and forth, and has a pair of left and right locks. 15a and 15b are formed, and by swinging back and forth, both opposing lateral outer surfaces of the rod-shaped member 14 are held between the locking portions 15a and 15b, and the state of locking and holding is achieved. It is configured such that it can be switched to an unlocked state in which it is released. This locking tool 15 also has a spring 16.
The swinging arm 17, which is connected integrally with the locking tool 15, is always elastically biased to the locked and held state by the door 11, and is switched to the unlocked state every time the door 11 swings into contact with the swinging arm 17. It is configured.

As the machine advances, the harvested stem culms that have been harvested and bundled are automatically moved backward with respect to the machine due to ground resistance each time the locking device 15 is released by the operation of the door 11. To the displaced boat 5,
It is configured to be received and recovered sequentially from the rear to the front.

In addition, in the embodiment, the frame body 14 that pivotally supports the boat 5
is automatically adjusted by moving it back and forth, but it may also be manually adjusted at appropriate times.
