Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting device corresponding to each row of planted culms, a conveying device for conveying the stalks to the rear auger, and a reaping section provided with a grounding body. Ordinary combine row crop header equipped with a plurality of side-by-side side-by-side vertical swing units that individually move up and down, and a conveyor that conveys the mowing stem culms collected by the auger to the rear threshing device. Regarding the structure.

[0002]

2. Description of the Related Art A conventional row combine header structure of this type of combine has been disclosed in, for example, Japanese Patent Laid-Open No. 61-
As disclosed in Japanese Patent No. 124312, each mowing processing unit can be simply moved up and down so that each mowing processing unit can individually follow up and down the unevenness in the field. .

[0003]

However, in the above-mentioned conventional structure, since each mowing processing section is supported by the ground contacting body in contact with the ground, when traveling around on a headland in a field, etc. However, there was a high possibility that the cutting processing unit would bounce due to the unevenness of the ground. Therefore, it is necessary to reinforce the attachment support structure of the mowing process part in order to increase the durability of the mowing process part against the bounce, resulting in high cost. The present invention has been made in view of the above circumstances, and is an ordinary combine harvester capable of preventing the reaping processing unit from unreasonably bouncing during traveling or the like, and capable of reducing the weight of the reaping processing unit. The purpose is to provide a row crop header structure for.

[0004]

In order to achieve the above-mentioned object, a row combine header structure of a normal combine harvester according to the present invention has the structure described above, in which the respective reaping processing sections are individually moved up and down. It is characterized in that it is suspended and supported by a common arm via a suspending tool in a state where it is allowed, and the arm is configured to be movable up and down. The operation and effect of this characteristic configuration are as follows.

[0005]

In other words, for example, in a headland of a field, by raising the arm and hoisting the entire mowing processing unit, all the mowing processing units can travel around without touching the ground. It is possible to prevent the processing unit from bouncing greatly when traveling.

[0006]

[Effects of the Invention] Therefore, as in the rounding of headland in the field,
When traveling at a relatively high speed, the simple operation of raising the arm can prevent the reaping processing unit from bouncing too much, and by eliminating the effect of the bounding, the weight of the reaping processing unit can be reduced. be able to. Further, since the reaping processing units are not individually raised so as not to come into contact with the ground, it is not necessary to provide a large number of elevating mechanisms for individually raising the reaping units, which also simplifies the structure and reduces the cost.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the combine. This combine has a traveling machine body 2 supported by a pair of left and right crawler traveling devices 1, 1, a threshing device 3, a grain storage device 4, and a control part 5.
In addition to being equipped with a drive section and a drive section, a row crop header 6, which will be described later, as a mowing section, a mowing pre-processing section 8 including an auger 7 and the like can be moved up and down around the horizontal axis at the front of the traveling machine body 2. It is installed and configured.

As shown in FIGS. 1 to 3, the pre-mowing processing section 8 is mowed by four row cropping headers 6 ... An auger 7 for collecting and conveying the harvested culm culms to one place in the left-right direction and sending the culm culm from the auger 7 to a threshing device 3 is configured by a conveyor 9. There is. The conveyor 9 and the auger 7 are supported by the platform frame 10. Each of the row crop headers 6 is attached to a transmission case 12 that is separately provided in a state in which power is taken out from a transmission rotation support shaft 11 that is erected in a lateral direction at a front end portion of the platform frame 10. Frame 1 for reaping processor
3, a pair of left and right conveyor belts 14 and 15 serving as a conveyor device supported by the reaping processing section frame 13 forms a long conveyance path in the front-rear direction. A disk-type rotary cutter 16 as a reaping device is arranged in a posture in which the front portions of the transport belts 14 and 15 are located below the wales. Conveyor belts 14 and 15 and disc type rotary cutter 16
As shown in FIG. 4, the driving force is transmitted from the transmission rotation support shaft 11 via the transmission mechanism in the transmission case 12 and the chain transmission mechanism 17. Then, the power is transmitted from the conveyor 9 to the power transmission rotary shaft 11 through the chain power transmission mechanism 18.

Then, a grounding body support arm 19 is attached to an intermediate portion in the front-rear direction of each mowing treatment section frame 13 of each mowing treatment section 6 so as to be vertically swingable around the horizontal axis X, and this grounding body support arm is also provided. A grounding wheel 20 as a grounding body is provided at the tip of 19. An electric cylinder 21 for raising and lowering the ground supporter arm 19 to change the ground height of the reaping processing unit 6 is provided across the reaping processing unit frame 13 and the grounding body support arm 19. Further, the pair of left and right arms 2 supported on the upper portions of the left and right side walls of the platform frame 10 so as to be vertically swingable around the horizontal axis P.
2 and 22 are attached in a state of extending forward. At the front ends of the arms 22 and 22, a horizontal bar 23 is erected and connected, and a chain 24 as a suspending tool is attached to the horizontal bar 23 and the grounding body support arm 19 of each mowing unit. It is provided. The arm 22 is provided with a lifting hydraulic cylinder 25 for vertically swinging the arm 22.

With the above structure, each cutting unit 6 is supported by the grounding wheel 20 in a floating state to the ground, and in that state, the chain 24 hangs down from the arm 22. I am in a state. As a result, the mowing processing unit 6 follows the unevenness of the ground when traveling for mowing.
Are movable up and down around the axis Q of the transmission rotary support shaft 11. Then, when reaching the headland during mowing, the arm 22 is operated to be lifted to lift the entire cutting processing unit 6 by the chain 24 by ascending and swinging around the axis Q, and the grounding wheel 20 is grounded. Will surface. Further, during the mowing traveling, the arm 22 is lowered so that each mowing processing unit 6 is grounded and supported by the grounding wheel 20,
The grain culm as a planting stem culm is sandwiched between the front ends of the transport belts 14 and 15, and is cut by the disc type cutter 16, and the cut culm culms are cut off by the transport belts 1 and 2.
The culm culms are discharged backward from the rear ends of the conveying belts 14 and 15 while being sandwiched between the shavings 4 and 15.

Next, the conveyor belts 14 and 15 will be described. As shown in FIGS. 5 (a) and 5 (b), each of the conveyor belts 14 and 15 is made of a molded elastic resin, and its shape is the outer peripheral surface of the belt forming a surface where these belts face each other. Further, a pair of upper and lower tips for sandwiching the cut culm are provided with projections 26. This protruding structure enables stable transportation of the posture of the harvested culm. Reference numeral 27 in FIG. 5B is a pulley guide protrusion provided so as to project so that the inner peripheral surfaces of the conveyor belts 14 and 15 form a ridge along the belt circumferential direction.

The present invention may be implemented as follows. (A) The suspending tool should be composed of a rod provided with a flexible portion such as a long hole. (B) The grounding body should consist of a sled.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the structures of the accompanying drawings by the entry.
