Description

[Detailed Description of the Invention] [Industrial field of application] The present invention cuts planted stem culms in the front part of the machine body, and conveys the cut stem culms backward while changing the posture so as to fall sideways. A cutting pre-processing unit is provided, and a bunching device for binding laterally cut culms and a collecting unit for collecting the bundled stalks are provided, and the plant end of the stalks is located on the upper side of the stalk conveying direction of the binding device. The present invention relates to a mowing and binding machine with a collecting device, which is provided with a disc-type cutting device that cuts and aligns the blades.

[Conventional technology]

As the conventional harvesting and binding machine with the collecting device, for example, as disclosed in JP-A-63-273408, along the blade edge of the cutting side on the root side surface of one cutting blade of the cutting device. There is a structure in which a guide surface for discharging chips is provided.

[Problems to be solved by the device]

In the structure of the above-mentioned reference, the guide surface efficiently guides and discharges the chips at the time of cutting the stock, and prevents the binding operation of the binding device from being prevented. This is to allow for smooth delivery to the bundling device by giving a stem culm feeding force to the bundling device.

However, in the above conventional structure, for example, when the culm to be conveyed is a long culm, the plant end position of the culm is determined by the position of the cutting position, and the tip side is inclined to be conveyed by the cutting pretreatment device. Since it is regulated by the surface, the middle part of the culm may be bent and conveyed. Then,
Before delivery to the binding device, the stocker side may project outward from the cutting surface on the conveyance side of the cutting device, which may disturb the stock end and lose the stock edge alignment function. .

Therefore, as a method for eliminating the above-mentioned drawback, as shown in FIG. 7, for example, as shown in FIG. 7, a guide plate (12) for receiving the cut culm plant end on the lower side of the cutting device (F) in the culm conveying direction is provided. )
It has been conceived of a structure in which the edge of the cutting device is arranged close to the outer peripheral edge of the cutting device (F).

However, in the above-mentioned improved structure, as shown in FIG. 8, chips at the time of cutting may be caught between the cutting device (F) and the edge of the receiving guide plate (12). However, new drawbacks such as a possibility that the smooth operation of the cutting device may be hindered and the transportation of the stems may be hindered occur.

The present invention aims to solve the above-mentioned problems.

[Means for Solving the Problems]

A feature of the present invention resides in that in the mowing and binding machine with a collecting device described at the beginning, between the binding device and the cutting device, a guide plate that receives the plant end of the stem culm immediately after the cutting and aligning by the cutting device is completed. It is arranged that a clearance is provided between the edge of the guide plate and the outer peripheral portion of the cutting device at an appropriate interval to allow passage of stalk cuttings. Is the street.

[Action]

In other words, the stem culms whose cutting ends have been cut and aligned by the cutting device have their root positions restricted by the guide plate from immediately after cutting to the bundling device, so that the root side does not project outward. Moreover, by providing the clearances at appropriate intervals, even if the chips at the time of cutting are rotated together by the rotational force of the cutting device, they are discharged toward either the left or right side, so that the guide plate There is little risk of being stuck in the edge or being caught between the cutting device and the edge of the guide plate.

[Effect of device]

As a result, even when the long culm is cut, it is possible to prevent the plant end from projecting outward by preventing the plant end from being disturbed, and it is possible to reduce the cutting function by cutting chips and to transfer the culm. It has become possible to prevent it from becoming an obstacle.

Moreover, there is an advantage that chips generated by a normal cutting action can be prevented from being scattered toward the binding device by the guide plate.
