Description

[Detailed description of the invention] The present invention is equipped with a pre-processing section that has a driving wheel pulling device, a reaping device, and a focused discharge device, and a weeding tool is attached to both left and right sides of the front end of this pre-processing section. This relates to a reaper.

Since the above-mentioned reaping machine is mainly designed for harvesting in dry fields, if it is used in wet fields, the front end of the pretreatment section sinks into the mud, making it impossible to work.

Therefore, measures have been taken to prevent the front end of the pretreatment section from sinking by attaching separate bodies on both sides of the pretreatment section when working in wet fields, but in the past, only the bridge body was simply fixed in a fixed position. , measures have been taken such as pivoting the front end to a reaping frame and moving the rear up and down.

However, in all of these structures, the tip of the bridge body is further away from the lower end of the weeding tool, and a gap exists between the two.
This method has the disadvantage that the planted shell culm gets stuck in this method, preventing smooth raising, and that the planted shell culm may be uprooted or cut.

This invention was devised to eliminate the drawbacks of the conventional structure, and the technical problem was that even when the bridge body was installed, the planted culm did not get into the gap between the tip of the bridge body and the bottom end of the weeding tool. The object of the present invention is to obtain a reaper that can be pulled up smoothly.

The technical measures taken to solve this technical problem are:
In a reaper, a pre-processing section having a pulling device, a reaping device, and a focusing and discharging device is disposed at the front of the running wheels, and a weeding tool is attached to both left and right sides of the front end of this pre-processing section. A large bridge body to which a weeding rod that protrudes diagonally rearward and upward is fixed can be installed and removed at the bottom of both left and right sides near the front end of the pretreatment section, allowing the height to be adjusted freely within the range from a position close to the lower end of the weeding tool to an appropriate lower position. In addition to being able to be mounted, the tip of the weeding rod on the machine body is located in front of the weeding tool and on an imaginary straight line in the front-rear direction along the direction of movement of the machine passing through the tip.

The above technical measures work as follows.

When the bridge body is installed, the weeding rod installed at its tip is located in front of the weeding tool and overlaps with it in the vertical direction.
The front part of the gap between the tip of the bridge body and the lower end of the weeding tool is completely covered by this weeding rod, which effectively prevents the planted shell culm from entering this gap. Since it is on the same straight line as the weeding tool, the planted culm can be transferred and guided smoothly from the weeding rod to the weeding tool.

In this way, the present invention is able to prevent the planted culm from entering the gap between the tip of the bridge body and the lower end of the weed divider by simply attaching the weeding rod to the tip of the bridge body. To,
The smooth receptacle of the planted culm from the weeding rod to the weeding tool allows for splicing, which has the advantage of allowing good and smooth raising of the planted culm without having to pull out or cut it. be.

Embodiments of the present invention will be described below based on the drawings.

At the rear of the fuselage, an engine 1 and a mission case 2 are directly connected side by side on the left and right, and a preprocessing section 5 is connected to the front ends of cylindrical frames 3 and 4 extending forward from each side.

Further, a transmission case 6 extends forward from the transmission case 2 under the frame 4 so as to be able to swing vertically, and one running wheel 7 located between the left and right frames 3 and 4 is attached to the shaft at the front end of the transmission case 6. supported.

At the front of the pretreatment section 5, a pulling device 8 and a weed cutting frame 9 are arranged in parallel and opposite each other, and behind these, a culm guide plate 10 and a reaping device 11 are provided. A convergence and discharge device 12 is provided at the bottom of the culm, which bundles the harvested and transversely fed culms in fixed amounts and discharges them laterally outward.

The focused discharge device 12 is fixed to the lower side of the pre-processing section frame 13, and is pulled up to the front end of a plate support bracket 14 bolted to the front of the device 12, which also serves as a bonnet for the lower end of the device 8. A weeding tool 15 is also attached.

Further, a support arm 16 for supporting the tip of the weeding frame 9 extends from the lower part of the other lateral side of the pre-processing section frame 13, and a weeding tool 17 is attached to the tip of the support arm 16 via a bracket 42. There is.

A culm guide rod 18 that projects into the pulling path extends upward from the weeding tool 17, and its upper end 18a is pressed flat and bolted into the weeding frame 9. ing.

This guide rod 18 has the function of pulling up the introduced culm at the starting end of the lifting, guiding it to the side of the claw 19 so that it receives the action of the claw 19, and receiving the claw 19 from below to form the weeding frame 9. It has a function of guiding the toe guide groove 20 that is formed.

Further, a shaft (not shown) for transmitting power to the pre-processing section is installed inside the frame 4 on the mission case 2 side.

Further, an arm 22 with an arcuate long hole 21 is erected from the wheel transmission case 66, and a bolt 24 is inserted through the arm 22 and a bracket 23 fixed to the lower part of the frame 4. The transmission case 6 can be fixed at any swinging position by tightening a cap nut 25 screwed onto the tip of the transmission case 24.

Further, a rise limit regulating piece 26 sandwiched between the bracket 23 and the nut 25 is inserted into the bolt 24, and the contact between the lower end side of this regulating piece 26 and the upper surface of the transmission case 6 prevents the transmission case from rising further. 6 is being prevented from rising.

In addition, if this regulating piece 26 is removed, the transmission case 6 will open with the elongated hole 21.
When large-diameter wheels are used for wet paddy work, the restriction piece 26 is attached to set the limit of ascent low, so that the ascending wheels 7 do not come into contact with the transmission case 2, etc. Furthermore, when small-diameter wheels are used for dry field work, the above-mentioned contact does not occur, so the restriction piece 26 is removed to increase the lifting limit, and the wheels 7 are raised to the maximum extent so that the aircraft can be lowered sufficiently. That's what I do.

The structure of the reaper is as described above, and in the present invention, for wet paddy work, bodies 27 and 28 for preventing subsidence are installed at the bottom of both the left and right sides near the front end of the pretreatment section 5, and the height is increased using the following structure.
