Description

[Detailed description of the invention] [Field of industrial application] The invention consists of a needle for wrapping a string around a grasshopper in a sideways position, a bill and a holder for forming a knot in the string wrapped around a grasshopper, and a holder for wrapping a bundled grasshopper. The present invention relates to a bundling device for a rush harvester, comprising a discharge arm that sends out.

[Conventional technology]

Taking conventional rush harvesting machines as an example, since rush grass is long and has thin stems, there are machines that hold the cut rush grass sideways, that is, in a fallen position, to prevent it from bending. (For example, Japanese Utility Model Application Publication No. 60-74526) has also been devised, in which a predetermined amount of rushes held in a horizontal position are tied together using a binding device.

[Problem that the invention attempts to solve]

Here, considering the case where the rushes held in a sideways position as described above are bound and discharged using a binding device comprising a needle, a bill, a holder, and a discharge arm, this kind of binding device cannot Since the rush is fed almost continuously into the space, when the binding operation starts and the needle operates,
The rush of rushes being sent to the binding space will be separated into those that will be tied and those that will not be tied.

However, because rushes are long, even if the needles are used to separate those that are bound and those that are not, the flexible parts of the tips of the rushes may become entangled with each other. When the bundled rush is released by the operation of the release arm, the tip of the rush may be damaged, so there is room for improvement.

The purpose of the present invention is to make reasonable modifications so that even if the tips of the tied and unbound rushes become entangled, when the tied rushes are released, each rush will be separated. The aim is to obtain a binding device that does not damage the tip.

[Means for solving problems]

The feature of the present invention is that in the binding device having the above configuration,
Before the ejection action of the ejection arm starts, the ejection arm enters the gap formed between the grass in the binding space and the grass on the path leading to the bundling space by the plunge operation of the needle from a position near the needle. ,
The separation member that moves toward the tip of the rush is provided, and its functions and effects are as follows.

[Effect]

If the above characteristics are configured as shown in FIGS. 1 and 2, for example, when the bundling operation is performed, the protruding action of the needle 17 causes the separating member 23 to enter the gap G formed between the rushes. As this separating member 23 moves toward the tip side of the rush, the rush that is bound R _s and the rush R _t that is not bound are separated.
The combing action of the separation member 23 widens the gap between the two, resulting in separation.

In particular, since the direction of movement of the separating member 23 is toward the distal end, separation can be performed without applying excessive force such as bending the rush.

[Effect of idea]

Therefore, even if the tip of the bundled rush and the tip of the unbound rush are intertwined due to the modification of providing a separation member, when the bundled rush is released, each rush will be separated. A binding device that does not damage the tip was obtained.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 3 and 4, a pair of left and right weeding devices 1, 1 are driven and rotated, and a pair of left and right pulling devices 2 are used to introduce and pull up the planted grass from the weeding devices 1, 1. , 2, a clipper-type reaping device 3 that cuts off the roots of the raised rush grass, a horizontal conveyance device 4 that grips the upper part of the cut grass and sends it laterally, and a roots of the rushes that are sent by the horizontal conveyance device 4. The sorting device 5 rakes out the waste grasses while being locked and conveyed with the side facing forward (right side in Fig. 3), and the grass grass after the sorting process set in a fallen position by the action of the sorting device 5 is tied up. A rice grass harvesting unit comprising a binding device A and a deck 6 for placing bundles of bundled rice grass is connected to a traveling machine body 7 consisting of an agricultural tractor to constitute a two-row rice grass harvesting machine.

As shown in the figure, the traveling body 7 is used with the driver's seat 8, steering handle 9, etc. of an agricultural tractor being turned in the opposite direction with respect to the body of the tractor. is transmitted via the transmission shaft 10, and
The unit is connected so that the ground level can be adjusted by operating a lift arm 11 provided on the tractor.Next, the structure of each device provided in the unit will be explained.

The weeding device 1 includes a rod 1a that is gently curved in a forward downward posture, the front end of which is supported via a ball joint 13, and this rod 1a that draws a spindle-shaped trajectory. A mechanism 1b that is driven to rotate;
The front end position of one is located forward of the other. The lifting device 2 includes a pair of upper and lower sprockets (not shown), an endless chain (not shown) wound around these sprockets, a large number of undulating claws 2a provided on the endless chain, and a case 2 that houses these.
The horizontal conveying device 4 consists of a large number of pulleys 4a that rotate about vertical axes, and a pair of clamping belts 4b, 4b that are wound around these pulleys and made of a flexible material so as not to damage the rush. The sorting device 5 consists of
A large number of undulating pawls 14 are attached to an endless chain (not shown) that is wound around a pair of front and rear sprockets (not shown).
and currant parts 5A, which are arranged vertically in three rows and arranged inside the case 15, and currant parts 5.
It consists of a pair of left and right rotating drums 5B for discharging the waste grass raked by step a further forward,
In addition, in order to assist in feeding the rushes after the sorting process to the binding device A side on the plant base side, belts with protrusions 16, 16 are installed.
is provided.

During the harvesting process, the rushes whose stems have been cut are placed in a position where the stems face forward in order to receive sorting action while their upper parts are held by the horizontal conveyance device 4. They are bundled by the binding device A and released onto the deck 6.

The binding device A also includes a needle 17 for wrapping a string around the rush, as shown in FIGS. 1 and 2.
, a building 18 that forms a knot in a string wrapped around the rush grass, a holder 19, a discharge arm 20 that sends out the tied bundle of rush grass onto the deck 6, and a packer 21 that sends the rush grass to the binding space S. These devices are operated by the power from the transmission case 22, and furthermore, the rice harvester separates the bundled rice grass and the untied rice grass so that the bundle of rice grass immediately after binding is reliably sent out by the discharge arm 20. A separation member 23 is provided to facilitate separation of the bundle from the rush.

That is, this separation member 23
The rush R _s in the bundling space S due to the rushing action of
Before the discharge action of the discharge arm 20 starts, the needle 17 enters into the gap G formed between the rush R and the rush _R on the path T leading to the binding space S, and is directed toward the tip of the rush. The driving timing and the like are determined so that the tip moves in a loop-like manner, and the operation locus on the tip side is formed in a loop shape as shown in FIG.

The separation member 23 has a swing link 24 pivotally supported at its base end and a drive crank 2 at its intermediate part.
5 are connected to each other, and the drive crank 25 is connected to the crankshaft 17a by two chain transmission mechanisms 26, 27, an intermediate shaft 28, and a bevel transmission mechanism so as to be driven in synchronization with the crankshaft 17a of the needle 17. They are interlocked and connected via 29.

[Another example]

In addition to the embodiments described above, the present invention may have a structure in which the separating member moves in parallel, or may be driven by a dedicated actuator such as an electric motor.
