JPS5854910Y2 - Cutting blade pressing device in a reaper - Google Patents

Description

[Detailed Description of the Invention] This invention relates to a reaping pressing device for preventing a movable reaping blade from floating relative to a stationary receiving blade.

During the reaping operation, the reaping blade floats up from the receiving blade due to the grain culm, and this is suppressed by the lifting prevention pressing piece attached to the dividing rod attachment pipe, and the wide part of this pressing piece prevents the lifting of the cutting blade from the receiving blade due to the grain culm. The culm is formed to cover the tops of the receiving blades adjacent to the left and right sides of the dividing rod attachment pipe, and the culm that has progressed to the left and right sides of the dividing rod attachment pipe is attached to the left and right edges of the wide part of the pressing piece. The applicant proposed a device designed to ensure that the cutting operation is carried out reliably by being guided far away to the left and right from the pipe for attaching the weeding rod and between the receiving blade and the reaping blade. No. 125908 (Jitsukai Sho 5
3-42939).

During weeding, the approaching culms strongly collide with the pressure piece as the reaper advances, so this pressure piece must be firmly fixed to the weeding rod attachment pipe without shifting. However, this fixing means must be constructed so as not to impede the flow of the grain culm.

Therefore, in this invention, a pressing piece that is V-shaped in plan view and prevents floating is provided on the reaping blade that reciprocates on the fixed receiving blade installed near the bottom of the weeding rod attachment pipe. In a reaper in which the wide part of the pressing piece covers the top of the receiving blade adjacent to the left and right sides of the pipe for attaching the grass dividing rod, the long groove formed at the tip of the pressing piece is attached to the pipe for attaching the grass dividing rod. A reaper that is engaged with a frame integral with the grass cutting rod, and the rear part of the pressing piece is fixed by being pressed with a bolt to the grass dividing rod mounting pipe so that it does not protrude from the left and right sides of the grass dividing rod mounting pipe. The long groove engages with the frame and is pressed by the bolt to firmly fix the pressing piece. Since the bolt does not protrude from the bolt, it is designed to prevent the culm during shedding from becoming entangled with the bolt.

Next, its specific structure will be explained based on one embodiment shown in the drawings.

A V-shaped pressing piece 4 is attached to the lower part of the grass divider attachment pipe 1.

A receiving blade 2 on the fixed side of the clipper type reaper is supported by a machine body 8, and a reaping blade 3 that slides on the upper surface of the receiving blade 2 is provided to reap uncut rods by the clipper action.

The V-shaped pressing piece 4 is located on the upper surface of the reaping blade 3, and is used to press the reaping blade 3 and prevent it from floating.
is attached below the pipe 1 for attaching the splitting rod.

That is, the long groove 15 formed at the tip of the pressing piece 4 has a frame 9 projecting from the front part of the lower surface of the pipe 1 for attaching the weeding rod.
The rear wide portion 5 of the pressing piece 4 is brought into contact with the upper surface of the reaping blade 3, and the wide portion 5 is prevented from protruding from the left and right side portions of the weeding rod attachment pipe 1. It is pressed and fixed by a bolt 10 passing through the branch rod attachment pipe 1.

The pressing force of this bolt 10 is adjusted by inserting it into a nut 11 welded to the pipe 1 for attaching the splitter rod, and the lock nut 12 allows the bolt 11 to be tightened.
loosening is prevented.

This pressing piece 4 is attached below the pipe 1 for attaching the weeding rod, and the front part is formed to have a width smaller than the diameter of the pipe 1 for attaching the weeding rod. It is wide and approximately V-shaped.

In the figure, reference numeral 13 is a lifting rod, and 14 is a grain rod transfer chain case.

The cutting blade pressing device according to this invention is constructed as described above, in which the wide portion 5 of the pressing piece 4 presses the top portion 6 of the receiving blade 2 adjacent to the left and right sides of the weeding rod attachment pipe 1. Since it is provided in a covering manner, there will be no gap between the dividing rod attachment pipe 1 and the receiving blade 2 or the pressing piece 4.
Grain culms are no longer caught between the weeding rod attachment pipe 1, the receiving blade 2, and the pressing piece 4, and reaping is carried out smoothly.

Since the tip of the pressing piece 4 is engaged with the frame 9 that is integrated with the weeding rod attachment pipe 1, the pressing piece 4 does not shift laterally and is pushed against the receiving blade 2 by the bolt 10. The pressure can be adjusted freely to ensure a suitable cutting operation at all times, and since this bolt 10 is screwed into the weeding rod attachment pipe 1 so as not to protrude from the outside thereof, This invention allows the reaping work to be carried out smoothly, since the culms during weeding do not become entangled with the bolt 10.
