Description

[Detailed explanation of the invention] The reaping frame in conventional reaping and tying machines was arranged laterally with the rear part of the reaping blade along the ground, so weeds and straw debris that climbed over the reaping blade were attached to the reaping blade and the reaping frame. This has the drawback that it gets stuck between the grain culm and the frame, accumulates on the cutting blade, and becomes an obstacle to the cutting of the grain culm into the cutting blade and the lateral movement of the reaped grain culm.

In this invention, weeds, straw, and mud that have climbed over the cutting blade can easily pass backward through the wide space below the chain case that extends from above the transmission case of the binding device on one side of the cutting blade to the other side, causing blockages. The purpose of the present invention is to provide a reaping and tying machine capable of smoothly reaping and horizontally transporting grain culms without causing or accumulating grains. A chain case extending toward the other side is mounted on the upper surface of the transmission case in a superimposed manner, and a side frame is attached to the other end of the chain case, and the side frame, the chain case, and the transmission case are used to form a cutting blade. It is characterized by a gate-shaped space formed at the rear of the vehicle when viewed from the front and rear directions.

The embodiments shown in the drawings will be explained below.
Reference numeral 1 denotes a frame extending rearward from a transmission case 3 which has wheels 2, 2 pivotally supported at the bottom, and is equipped with an engine 4. A handle 5 is attached to the upper part of the transmission case 3, and a handle 5 is attached to the left side. A main shaft 7 is housed inside a cylindrical frame 6 extending forward from the main shaft 7.

8 is a binding device provided on one side of the cutting blade 9,
The front part of the transmission case 10 is equipped with a knot part 11 and a discharge arm 12, the rear part across from the focusing part 13 is provided with a packer 14 and a needle 15, and a door is provided outside the focusing part 13. There is.

Reference numeral 16 indicates a sprocket 18 attached to the upper part of the packer shaft 17 and a crankshaft 19 that drives the cutting blade 9.
A sprocket 20 is attached to the main shaft 7, a sprocket 23 is attached to the lower part of the vertical shaft 22 which is interlocked with the main shaft 7 via a clutch 21, and the sprockets 18, 20, 23 are connected to each other as shown in FIGS. 2 and 3. It is a flat chain case with a flat top and bottom surface, which houses a chain 24 which is wound around in a substantially equilateral triangular shape, one side of which is screwed onto the transmission case 10 of the binding device 8, and the other end As shown in FIG. 2, the section extends to the rear of the other end of the cutting blade 9, and the front surface is formed into a gently sloped grain culm guide surface 16a.

The connecting plate 25 screwed onto the lower surface of the other end of the chain case 16 is welded to the upper part of a side frame 26 which has a U-shaped cross section and also serves as a side cover. The chain case 16 and the transmission case 10 are connected in a gate shape, and a wide space A is formed at the rear of the cutting blade 9 as shown in FIG.

In addition, a weeding body 28 is attached to the sliding body 27 having an L-shaped cross section and welded to the front part of the side frame 26, and the support 29
The holding cylinder 30 of the vertical shaft 22 supports a grain culm pulling body 31, and although not shown, a weeding body is also attached to the front part of the sliding body protruding from the transmission case 10. A lifting guide is provided at a portion corresponding to the culm lifting body 31.

Further, the lower part is screwed onto the lower surface of the transmission case 10, the rising part is along the side surface facing the space A of the transmission case 10, and the upper part is screwed onto the lower surface of the transmission case 16.
A Z-shaped plate 32 screwed onto the lower surface of the transmission case 3 is attached to the front end of a mounting frame 33 extending forward from both sides of the front portion of the mission case 3.

In addition, in the drawing, 34 is a guide plate for guiding the harvested grain culm to the binding device, 35 is a string ball, and 36 is a main shift lever.

In the above-mentioned device, the grain culm that has been divided by the weed cutting body 28 is raised by the grain culm pulling body 31 and cut by the cutting blade 9, and the upper part is the guide plate 34, and the stock base part is the front part of the chain case 16. Guided respectively towards the binding device 8, the packer 14 engages the converging part 13, the needle 15, the knot part 11 and the discharge arm 1.
2 binds the focused grain rods and releases them to the side.

During the above-mentioned cutting and tying operation, weeds, straw, mud, etc. pass over the cutting blades 9, flow into the space A, and are discharged to the rear as the machine moves forward.

As described above, the present invention provides a transmission case of the binding device on one side of the cutting blade, a chain case extending toward the other side is attached to the top surface of the transmission case, and a chain case is attached to the other end of the chain case. A side frame is attached, and the side frame, the chain case, and the transmission case form a gate-shaped space at the rear of the cutting blade when viewed from the front and rear directions, so that weeds, straw, and mud that climb over the cutting blade during mowing work can be removed. As the machine moves forward, it passes backward through a space formed by a transmission case on one side of the cutting blade, a side frame on the other side, and a chain case extending over the top of the transmission case, and the mud, etc. Grain culms can be smoothly harvested and moved laterally without being clogged between the reaping frame and the cutting blade or being deposited on the cutting blade.
