Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has one end side pivotally supported on one side of the bundling space via a pin, and an intermediate part thereof pivotally connected to an eccentric part of a driving rotary body. Equipped with a discharge arm 14 capable of forcibly discharging the stem culm bundle in the bundling space to the outside by a circulation movement accompanying the drive rotation of the drive rotary body, and a stem culm bundle discharge port side from the bundling space. The present invention relates to a reaping and tying machine having a collection section that can collect and hold a plurality of bundles of stems and culms.

This type of reaping and tying machine collects a plurality of stem culm bundles discharged from the tying space in a collecting section, and then releases the stem culm bundles in this collecting section all at once into the field. During post-processing such as sun-drying and threshing, the stalks are bundled into small bundles that are easiest to handle, while the stem and culm bundles released into the field are collected in large units, making subsequent collection work more efficient and easy. However, conventionally, in order to discharge the plurality of stem culm bundles collected in the collection section, a dedicated discharge tool was provided separately from the discharge arm. Therefore, a discharge tool dedicated to the plurality of collected stem culm bundles and a drive mechanism for circulating the same within the collection section are required, which makes the entire discharge structure complicated and large, which is disadvantageous in terms of manufacturing and economy. .

The present invention makes it possible to economically advantageously switch between the two types of discharge action as described above by simply modifying the structure of one discharge arm that is originally equipped in this type of reaping and tying machine. In the above-mentioned device, the swinging fulcrum pin position of the ejection arm can be freely changed and fixed in the longitudinal direction of the arm, so that the ejection arm 14 can be moved into the bundling space 6. The system is configured to be switchable between a first state in which a bundle of stem culms is forcibly discharged to the collecting section 7 side, and a second state in which a plurality of stem culm groups collected in the collecting section are forcibly discharged to the outside. It is characterized by

That is, in the case of the present invention, one discharging arm originally equipped with this type of reaping and binding machine is used, and the swing fulcrum pin position of this discharging arm is configured to be freely changeable and fixed in the longitudinal direction of the arm. With this simple modification, it is possible to freely switch between the two types of release states as described above. Compared to conventional systems that include a dedicated discharge tool for forced discharge and a drive mechanism to circulate the device within the collection section, the entire discharge structure is simpler and more compact, making it easier to manufacture and more economical. We have now achieved a device which has an advantageous configuration and can be used by arbitrarily switching between two types of release action.

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

Figure 1 shows a single-row mowing type binder, which pulls planted stem culms rearward and upward in front of a running machine main body A having a pair of left and right running wheels 1 and a walking control handle 2. A hair raising device 3 and a clipper type reaping device 4 for cutting the base of the raised planted stem culm are arranged, and the traveling wheels 1,
1 and the reaping device 4, there is a binding device 5 for tying and discharging the reaped stem culms in a fixed amount at a point near the plant base in an almost upright position. It opens in the front-rear direction at or approximately at the center in the width direction, and is arranged in a gently inclined position facing toward the discharge port 7a of the collecting section 7, which will be described later, with respect to the left-right direction. The binding space 6 of this binding device 5 is connected to the discharge port side, and the binding device 5
A stem culm mounting deck 7A and a stem culm guide rod 7B are provided in a horizontally long space having a discharge port 7a that opens on one side through the space between the culm and the running wheels 1, 1, so that a plurality of stem culm bundles can be almost erected. Collection unit 7 that can be collected and held in a posture
and on the discharge port 7a side of the collection part 7, in contact with the base of the collected stem culm group to be discharged,
A stock removal rod 8 is provided which allows the stock to be laid down in a state where it is located on the laterally outer side of these ears.

The binding device 5 is constructed as follows.

That is, as shown in FIGS. 2 and 3, on one lateral side of the binding space 6, a constantly driven packer 9 for scraping the reaped stem culms into the binding space 6 and a needle 10 for supplying a binding cord are installed. The other side is provided with a building 11, a knotting mechanism 13 having a string holder 12, and a discharge arm 14 driven in synchronization with the knotting mechanism 13, and a discharge arm 14 driven in synchronization with the bill 11, and a focused pressure sensor of the reaped stem culm on the discharge outlet side of the binding space 6. A door 15 is provided.

The needle 10 and the knotting mechanism 13 are configured to bind the reaped stem culms collected in the binding space 6 by synchronized driving based on the detection of a focusing pressure of a certain level or more by the door 15.

Connect one end of the ejection arm 14 to the pin 1 on the fixed side.
6 is externally fitted and supported via the elongated hole 17,
The intermediate portion in the longitudinal direction is pivotally connected to an eccentric portion of a timing gear 18 which is a component of the knotting mechanism 13, and the circulation movement accompanying the intermittent drive rotation of the timing gear 18 causes the inside of the bundling space 6 to be rotated. It is configured to forcibly release the tied stem and culm bundles.

The arm 19 having the swing fulcrum pin 16 is configured to be able to swing freely in the far and near directions with respect to the timing gear 18, and the arm 19
Spring 2 biasing and holding 9 in two positions: a position away from the timing gear and a position close to the timing gear.
0 and stoppers 21A, 21B are provided, and the swing fulcrum pin 1 due to the swing of the arm 19 is provided.
By changing the position of 6, the discharge arm 14 is brought into a first state in which the stem culm bundles in the bundling space 6 are forcibly discharged to the collecting section 7 side, and a plurality of stem culm bundles collected in the collecting section 7 are put in the first state. It is configured to be switchable to a second state in which the group is forcibly ejected outward.

Incidentally, instead of forming the elongated hole 17 in the ejection arm 14, as shown in FIG. It is also possible to separate the divided members 14A and 14B into attached members 14B, and to fit these two divided members 14A and 14B to the outside in a flexible manner.

The arm 19 may be switched manually, but it may be configured to switch automatically based on the detection result of a device that detects that a predetermined amount of stem culm bundles have been collected in the collecting section 7.
