Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting and binding machine.

[0002]

2. Description of the Related Art Conventionally, this type of mowing tying machine has been disclosed in, for example, Japanese Patent Application Laid-Open No. 9-65750, in which a cut culm is laid on a guide cover and laterally fed. It is well known that the base of the stock is bound by a binding device.

[0003]

However, in the above-mentioned conventional structure, a gap is easily formed between the scraping rotary member and the guide cover, especially at an intermediate portion of the grain stem in the stem direction. Therefore, when the grain culm amount of the harvested grain culm is small, the grain culm may not be caught on the nail of the swirling rotary body, and there is a high possibility that the feeding action does not work sufficiently in the middle part of the stem. Even if the transportation of the stock gawa is done well, the transportation at the tip is sometimes delayed,
As a result, there is a possibility that problems such as a disturbed binding posture may occur.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a cutting and tying machine capable of satisfactorily feeding cut culms to a tying device.

[0005]

[Means for Solving the Problems]

(Structure) The cutting and tying machine according to claim 1 of the present invention is provided with a traversing device that traverses the cutting culm to the tying device in a state of leaning against the guide plate in an upright posture, and faces the guiding plate. At the position, a scraping rotator that is driven to rotate around an upper and lower axis so as to scrape the middle part of the culm of the harvested grain culm into the binding device is arranged, and the scraping rotator is elastically turned toward the side. The band plate member to be urged is cantilevered by the guide plate so as to be movable in a distance direction with respect to the scraping rotary member.

(Operation) According to the first aspect of the present invention, since the band plate member is provided with the rotating body being elastically urged from the guide plate side, the harvested grain stalk is scraped. Even if it moves between the rotating body and the guide plate, the intermediate part of the culm of the harvested grain culm is positioned closer to the rotating body by the band plate member, and is locked to the claw of the rotating body. Therefore, under the action of the scraping rotator, the harvested culm can be smoothly moved without stagnation in the tying device and without delay in transport of the spike tip side.

(Effects) Therefore, according to the configuration of the first aspect of the present invention, the harvested grain culm does not stay between the swirling rotating body and the guide plate, and there is no delay in transporting the spike tip side.
Since the bunches are transferred to the tying device satisfactorily, it is possible to avoid problems such as disturbance of the tying posture, and to obtain good tyed grain culms.

(Structure) According to a second aspect of the present invention, in the cutting and binding machine according to the first aspect, the cutting grain stalks are scraped from the binding device by the binding device side end of the guide plate. A receiving portion for receiving and restricting the return to the rotating body side is provided.

(Operation) According to the structure of the second aspect of the present invention, the receiving plate is provided at the end of the guide plate on the side of the binding device for receiving and regulating the cutting grain stalk from the binding device to return to the rotating body side. Once the grain culm has been transferred to the binding unit, the grain culm once transferred to the binding unit is regulated by the receiving part so that the rotating body is not returned, and the grain culm transferred later is also transferred. Can be prevented.

(Effects) Therefore, according to the configuration of the second aspect of the present invention, the harvested cereal culm that is later transferred to the binding device is also smoothly transferred to the binding device and temporarily transferred to the binding device. Since the culms do not flow backward, the stalks can be satisfactorily bound without disturbing the binding posture.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of a mowing and binding machine. This cutting and binding machine is for two-row cutting, and a pair of right and left raising devices 1 for raising a grain culm in a field.
a, 1b, a clipper-type reaper 2 that cuts the raised stem of the raised grain stalk, a lean guide plate 3 for leaning the harvested grain stalk in a backward tilted posture, and a leaning guide plate 3 for leaning. The horizontal feeding device 6 including the tip-side locking and conveying device 4 and the stock base locking and conveying device 5 for conveying the grain culm in the horizontal state to the side of the machine body, and binds the grain culm at the end side of the horizontal feeding device 6. And a binding device 7.

As shown in FIG. 2, of the cereal stalk introduction paths of the pair of right and left elevating devices 1a and 1b, the introduction path A on the left side.
The stem portion of the cereal stem that is introduced through is guided by a guide strip 9 that extends rearward with one end fixed to the left weed support rod 8a at the rear of the raising device 1a. While being guided, the middle part of the culm is guided by the leaning guide plate 3. Then, at the rear part of the cereal stalk introduction path A of the left erecting device 1a, the root of the cereal stem introduced from the left elevating device 1a and guided by the guide strip 9 is scraped. 1st star wheel 1 for changing the transfer direction of the grain stalk from the direction along the front-rear direction to the sideways direction by giving
0 is provided so as to rotate freely around the vertical axis Y1. The first star wheel 10 is rotated by a projection protruding at predetermined intervals on the chain of the stock lock transporting device 5. In the figure, reference numeral 14 denotes an auxiliary scraping rotator arranged at a position slightly higher than the first star wheel 10 and the guide strip 9. Further, of the cereal stalk introduction paths of the pair of left and right elevating devices 1a and 1b, the cereal stem introduced through the introduction path B on the right side is the elevating device
In the rear part of b, one end is fixed to the weed supporting rod 8b between the introduction paths A and B, and guided while being restricted in position by a guide body 11 extending rearward. The right raising device 1b is located behind the right raising device 1b.
b, a rubbing action is applied to the root of the cereal stem that has been guided by the guide body 11 to change the transfer direction of the cereal stem from the longitudinal direction to the lateral direction, and to the binding device 7. A second star wheel 12a for feeding is provided so as to be rotationally driven around the vertical axis Y2. As shown in FIGS. 1 and 3, the second star wheel 12a is driven to rotate slightly above and below the second star wheel 12a via the transmission shaft and around the vertical axis Y3 which is slightly raised. A third star wheel 12b is provided as a scraping rotary member. The third star wheel 12b gives a feeding action to the binding unit 7 to an intermediate portion of the transported grain culm in the culm direction.

The third star wheel 1 which feeds the cut culms conveyed by the lateral feeder 6 to the binding unit 7 while scraping the culms.
At a position where the guide plate 3 leans against the waist 2b, the band plate member 13 cantilevered at the left hand position where the upper hand of the horizontal feeder 6 can convey the material is farther from the third star wheel 12b. The binding device 7 is extended movably. As shown in FIG. 3, the band plate member 13 is made of a spring plate material, and
b is configured to be elastically biased,
The free end portion is bent, and the bent tip is engaged with the through hole 14 formed in the leaning guide plate 3 so that the free end portion can be inserted and retracted. This bent portion constitutes a receiving portion 13A for receiving and restricting the grain stem transferred by the binding device 7 to the wrinkle so as not to return to the upper side of the conveyance.

According to the above configuration, even when the transported grain culm amount is small, the third star wheel 12b is pressed by the band plate member 13 at the intermediate portion of the culm of the grain culm during transport,
Since the grain stalk enters into the rotation locus of the third star wheel 12b, the grain stalk is sent to the binding device 7 with high reliability. When the grain stem amount is large, the band plate member 13 leans and retreats to the guide plate 3 side by the pressure received from the grain stem, and the third star wheel 12b and the band plate member 13
