Description

[Detailed description of the device]

[0001]

[Industrial applications]

 TECHNICAL FIELD The present invention relates to a weed for a uncut stem culm in a combine of a type in which a cutting section can slide laterally.

[0002]

[Prior art]

 Conventionally, this type of weeding mechanism has a front weeding rod extending from the weeding tool at the front end of the mowing section to the front of the crawler traveling device, as shown in, for example, Japanese Utility Model Laid-Open No. 3-92933. A support member composed of a rear shunt rod extending from the front to the rear of the crawler traveling device and supporting both the rear end of the front shunt rod and the front end of the rear shunt rod is laterally adjustable with respect to the machine body. As a result, the front splitting rod and the rear splitting rod were made to be able to move laterally by swinging the rear fulcrum, respectively, to correspond to the lateral slide of the cutting section.

[0003]

[Problems to be solved by the device]

 The means of the above publication is to divide the weeding rod into front and rear split type to secure the support strength and rigidity, but to separate the uncut stem culm from the crawler to which mud adheres and the side of the supporting member that can move laterally. Due to the fact that the installation location of can only be set to a position just above the front of the crawler, a weeding rod is installed at a relatively low height. Even with this, the short rods and normal stem culms can fully exert the weeding function, but when the long rods are mowed, the tips of the ears hang down toward the machine body despite the fact that they are weeded. There was a risk of getting caught in the feeder. An object of the present invention is to provide a weeding mechanism on the uncut side in which there is no risk that the long rod will be caught in the carrying device in the combine of the above type.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is provided with a mowing part for cutting planted stem culms laterally adjustable with respect to the machine body within a predetermined range, and a side part of the machine body which is the uncut side. At the position, a weeding rod that extends from the weeding tool at the front end of the mowing section to the rear of the crawler traveling device portion is installed so that lateral movement can be adjusted with respect to the machine within a predetermined range. In order to dispose the auxiliary weed rod for long rods above the front of the weed rod, which is located on the side of the mowing part, this auxiliary weed rod should be adjusted so that It is characterized in that it is attached to and supported by a weeding rod through an adjusting mechanism that can be changed and adjusted.

[0005]

[Action]

 In other words, by providing an auxiliary weeding rod above the front part of the weeding rod located to the side of the mowing section, the tip of the long rod is prevented from falling into the mowing section by the two-step upper and lower weeding rods. By adjusting the height position of the auxiliary weed rod, the optimal weed state according to the length of the long rod can be realized. In addition, since the auxiliary weeding rod is attached to and supported by the weeding rod itself, which can be moved laterally, it is possible to move the auxiliary weeding rod laterally in response to the lateral sliding of the cutting section without a dedicated lateral movement mechanism. Become.

[0006]

[Effect of device]

 Therefore, by devising a mechanism to support the auxiliary weeding rod so that it can be adjusted up and down with respect to the front part of the weeding rod, a weeding mechanism that can prevent long rods from being caught in the cutting unit in a combine harvester with a horizontal sliding unit is provided. It was possible to provide it economically and with good weeding regardless of the length of the stem. In addition, for example, it is conceivable that the front part of the weeding rod is composed of a one-stage adjustable up and down unit to adjust the position of the weeding action height according to the length of the culm. This is disadvantageous in that the adjustment area is narrow and the coordination of the weeding action with the rear part of the weeding rod, which has a fixed height, may be deteriorated and the supporting structure for the airframe becomes complicated.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. A side view of the combine is shown in FIG. 2, 1 is a mowing section, 2 is a crawler traveling device, 3 is a thresher, 4 is a control section, and 5 is a weeding tool. In this combine, the mowing unit 1 is provided so as to be capable of lateral slide movement adjustment within a predetermined range with respect to the machine body, and is adapted to cope with swivel cutting and split cutting. The lateral slide of the cutting unit is a known technique, and a description of its specific structure will be omitted.

A weeding mechanism A by a weeding rod C composed of a weeding rod front portion 6 and a weeding rod rear portion 7 is disposed on the left side of the uncut side machine body. As shown in FIGS. 1 to 3, the front part 6 of the weeding rod is composed of a front rod 6A made of a square pipe and a rear rod 6B slidably fitted in the rear end thereof. The bracket 8 fixed to the frame is supported by the frame 5a of the weeding tool 5, and the rear end of the rear rod 6B is connected to a ring part 9a at the tip of a support arm 9 mounted on the machine body so that the lateral movement is adjustable. is there. The rear part 7 of the weeding rod is composed of a rear rod 7B made of a square pipe and a front rod 7A slidably fitted in the front end thereof. The front end of the front rod 7A is connected to the ring portion 9a at the tip of the support arm 9. In addition, the rear end of the rear rod 7B is rotatably connected to the body at the rear position of the crawler traveling device 2 about the vertical axis P. The support arm 9 is supported by the machine frame 10 just above the front part of the crawler traveling device 2, and the support arm 9 is adjusted to the left and right positions by tightening and tightening the adjusting bolt 11.

Further, an auxiliary weed rod 13 for a long rod is provided above the weed rod front portion 6. That is, the hook-shaped tip claw portion 13a is inserted into the front end opening of the front rod 6A, and the front-rear intermediate portion is supported by the support tool 14 erected from the front rod 6A. The support tool 14 is composed of a mounting portion 14A and a supporting portion 14B, and the supporting hole 14a and the mounting bolt 14b are used to adjust the swinging movement of the supporting portion 14B with respect to the mounting portion 14A around the fulcrum X in the front-rear direction. This is possible, and by this means, is attached to and supported by the front part 6 of the weeding rod via an adjusting mechanism B which makes it possible to change and adjust the amount of protrusion of the auxiliary weeding rod 13 in the vertical direction. The lower portion and the front surface portion 15 of the side portion of the front rod 6A in the mounting portion 14A are chamfered so that the stem culms will not be scratched and damaged. The auxiliary split rod 13 is configured by internally fitting a separate rod 13B having a shape that hangs downward at the rear end of the main rod 13A made of a round pipe, and the bolt is tightened to project the separate rod 13B upward and rearward. The amount can be adjusted. This allows the auxiliary weed rod 13 to be used as a general-purpose component in that the starting position of the feed chain 16 differs depending on the model.

As shown in FIG. 4, the separate rod 13B is divided into upper and lower parts so that the upper rod 17 can be vertically extended and contracted with respect to the lower rod 18, and the upper rod 17 and the main rod 13A are flexible. The auxiliary weed rod 13 connected by the flexible hose 12 (for example, a resin bellows boot) may be equipped.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the invention is not limited to the configuration of the accompanying drawings by the entry.
