Description

[Detailed Description of the Invention] The present invention relates to a rice grass harvesting machine in which a transport route for cutting rice grass is provided in a substantially straight line along a route for introducing rice grass into a reaping device.

In this type of harvester, the grass that has already been cut and the uncut grass that will be cut are intertwined near the cutting device, which adds resistance to the transfer of the grass that has been cut to the conveyance route. The problem was that the transport posture of the machine was disturbed.

In view of the above-mentioned circumstances, the present invention aims to enable the division of cut and uncut grass near the reaping device, and to transport the cut grass without disturbing the posture. With the goal.

Next, embodiments of the present invention will be described in detail based on the drawings.

A pair of left and right dividing draft inner fittings 1, 1 protruding forward
A reaping device 2 that reaps the planted grass introduced between the plants, an elastic clamping and conveying device 3 that elastically clamps the harvested grass near the base and conveys it toward the rear and upward, and conveyed by the conveying device 3. While preventing the tip side of the rush from moving backwards, the part halfway in the direction of the culm is stopped and conveyed upward while following the movement of the plant base, and the cut rush is lifted centering on its upper end. A pair of front and rear locking conveyance devices 4 and 5 that swing and change the posture to a sideways posture, a lateral conveyance device 6 that pinches and conveys the grass in the sideways posture, and a sideways conveyance device that conveys the grass in the horizontal direction. A running vehicle body in which a sorting tool 7 for removing waste grass of a length less than a set length and a collection section 8 for collecting the selected high-quality grass are mounted on low-pressure tire wheels 9 and a control section 10 is extended in the front. A rice grass harvester is constructed so as to cut and collect rice grass as it travels.

A conveyance path R ₁ constituted by the elastic clamping and conveying device 3 is provided almost in a straight line with a rush introduction path R ₂ to the reaping device 2 between the dividing draft inner tools 1, 1.

Near the top of the reaping device 2 and the control section 1
The first and second rotating shafts 11 and 12 are located at the end far from the 0 and are freely rotatable around the vertical axes P ₁ and P 2 respectively in a state where they are distributed to the front and rear of the reaping device ₂ in a plan view. a first weeding tool 13 located on the front side of the reaping device 2 on the first rotating shaft 11, and a first weeding tool 13 located on the second rotating shaft 12 below the first weeding tool 13; The second one located on the rear side of the reaping device 2
The weeding tools 14 are respectively attached so as to be freely rotatable.

The first and second rotating shafts 11 and 12 are interlocked and connected by first and second gears 15 and 16 attached respectively, and the second rotating shaft 12 and the conveyance start end of the elastic clamping and conveying device 3 are driven. An arm 19 is interlocked with a pulley 17 via a crank mechanism 18 and is integrally rotatably attached to the first rotating shaft 11, and the dividing draft inner tool 1 on the side far from the operating section 10 is connected. Pivotally connected, the second weeding tool 14,
At the starting end of the cut grass transport path R ₁ on the rear side of the reaping device 2, around the vertical axis P ₂ between the position crossing this transport path R ₁ and the position retreated to the rear side of the path R ₁ . While swinging back and forth, the first weeding tool 13 is moved to the grass introduction path on the front side of the cutting device 2.
In the direction opposite to the second weeding tool 14 around the vertical axis P ₁ between a position crossing this introduction route R ₂ at the terminal end of R ₂ and a position retracted to the side in front of route R ₂ . It is configured to reciprocate in a displaced state over a predetermined angular range, and to reciprocate in the left-right direction of the machine over a predetermined angular range, with the dividing draft inner tool 1 centered on its front end.

The functions of the first and second weeding tools 13 and 14 will be explained in more detail. The planted straw that is introduced as the aircraft advances is handled by the first weeding tool 13 that swings back and forth.
When it swings forward and assumes a position evacuated from the rush introduction route _R1 , it enters the side of the reaping device 2. This forward swinging of the first weeding tool 13 causes the first weeding tool 13 to swing forward.
To separate the uncut grass located in front of the first weeding tool 13 from the grass located closer to the cutting device 2 and about to be cut, and to untangle each other to facilitate subsequent handling. It is something. The rush that has been separated and cut in this way is then subjected to the action of the second weeding tool 14. In other words, the cut grass is moved by the action of the second weed cutting tool 14, which swings forward in a posture that crosses the cut grass transport route _R1 .
The transfer of the tip to the lower side of conveyance is temporarily prevented, and the entanglement with the rush that has already been conveyed by the elastic pinching and conveying device 3 is untangled again. When the thus-understood mown grass swings rearward to the second weed splitter 14 and assumes a position where it is evacuated from the cut grass transport route _R1 , it enters the starting end of this route _R1 and the machine It is held and conveyed towards the rear of the machine.

Incidentally, the front end portion of the dividing draft inner tool 1 is connected to the mounting frame 20 so as to be slidable in the longitudinal direction of the machine body so as to allow the front end portion to swing.

The first gear 15 is configured to have a smaller diameter than the second gear 16, and the first weeding tool 13 is configured to have a smaller diameter than the second weeding tool 16.
It is configured to swing back and forth over a larger angular range.

In summary, the present invention provides the above-mentioned rice grass harvester with a position near the top of the reaping device at the end of the rice introduction path, a position crossing this introduction path, and a position retracted to the side in front of the path. A first weed cutting tool that reciprocates around the vertical axis is provided at the starting end of the grass transport route, and a position that crosses the transport route and a position that is retracted to the rear side of the route. Since it is characterized by being provided with a second weeding tool that swings back and forth around the vertical axis, the following effects are achieved.

In other words, the planted rice grass that is introduced into the grass introduction path as the aircraft advances will enter the cutting device side when the first weeding tool, which swings back and forth, swings forward and takes a position where it is evacuated from the grass introduction path. However, the entanglement with the grass that has already moved along the conveyance path is resolved, and as a result, the conveyance of the cut grass can be carried out in a good manner without disturbing its posture.

In particular, in the present invention, the second stage is used to separate the rush immediately after harvesting from the rush that has already moved along the rush transport route.
Before the weeding action of the weeding tool, the first weeding tool removes the grass that has not yet been cut by the cutting device, the uncut grass that is located in front of the machine, and the first weeding tool. By swinging forward, the uncut grass located in front of the machine body is separated from the grass that is about to be cut by the cutting device, and the grass is separated from each other by the first grass cutting tool. The straw that has been cut by the cutting device is then temporarily prevented from moving toward the lower side of the transport by the action of the second weed splitting tool, which swings forward to cross the cut grass transport path. Since the rice grass is separated from the harvested grass, there is an advantage that the separation effect between the grass immediately after cutting and the grass that has already moved through the grass transportation route is performed well.
