Abstract

PURPOSE:To carry out threshing only by plunging a reaping part of combine into grain culms piled in a field, by equipping the top position of reaping blade with a guide plate whose front side is vertically movable around the rear side thereof. CONSTITUTION:When a machine is advanced toward collected grain culms, a guide plate 30 is crawled into the lower part of the grain culms, grain culms bundles are sent over the guide plate 30 to an auger 16, fed from the auger 16 through a conveyor 37 to a threshing chamber of a thresher and threshed. In the case of a large amount of grain culms bundles, when a raking reel 14 is vertically moved by a cylinder 26 of vertically moving the reel in a state of the guide plate 30 crawled into the lower part of the grain culms bundles, the front end of the guide plate 30 is pulled by a connecting rod 35 and the front end of the guide plate 30 is rotated around a shaft 33. The guide plate 30 is sloped so the rear side is made low, the grain culms bundles on the guide plate 30 are smoothly reached to the auger 16 and fed from the auger 16 through the conveyor 37 to the threshing chamber of the thresher.

The reaping section includes a reaping section provided therein, and a conveyance device provided between the reaping section and the threshing device.

In a combine harvester having a cutting blade that cuts the roots of grain culms long in the left and right direction, and an auger that collects the cut grain culms provided behind the cutting blade, on the upper surface of the cutting blade, the front side of the cutting blade is This document describes a reaping section of a combine harvester in which guide rods are provided at predetermined intervals in the width direction and are lower and higher toward the rear so as to protrude from the front so as to contact the ground.

(Problem to be solved by the invention) A combine harvester cannot harvest grain culms near the ridges of a field. Grain culms near the ridges of a field are harvested manually with a sickle, accumulated at a desired position in the field, and finally harvested. was thrown into the auger of the combine harvester. The same applies to the above-mentioned known combine harvester.

However, if the cutting blade is devised, it will be possible to feed it to the auger and thresh it by thrusting it into the stacked sheaves harvested by hand with a sickle.

The present invention enables grain culms stacked in a field to be threshed with a combine harvester by simply providing a special guide plate above the cutting blade.

This is a conveying device that supplies grain culms to the

(effect) Next, we will discuss the effect.

(In the case of harvesting and threshing of rice, wheat, soybeans, adzuki beans) The present invention has the above-mentioned structure, and when harvesting and threshing of rice, wheat, soybeans, adzuki beans, etc. Remove the rod A and remove the rotating shaft cylinder of the guide plate 30! When the axle is pulled out, it can be removed from the reaping section frame 17.

Then, the mounting arm n is moved up and down by the reel vertical movement cylinder 9 to align the raking reel 14 to the height of the grain culm, and when the machine is moved forward in this state, the grain culm is divided by the 5-part weed body n and raked. The reel 14 rakes in the culm, and the culm is cut into a cutting blade! The harvested grain culm is further raked by the raking reel 14 and reaches the auger 16.
6 concentrates the grain culms at the base of the conveyor, and the conveyor! The grains g are supplied to the handling barrel 6 of the threshing device 3 for threshing, and are wind-selected in the wind-selecting chamber 8.

(When threshing rice, wheat, soybeans, and adzuki beans) Harvest rice, wheat, and soybeans near the ridges of the field by hand, feed this into the auger 16, and thresh it with the threshing device 3. In particular, in the case of adzuki beans, the harvested grain culms are sometimes piled up and left in the field for a certain period of time, and then threshed.

In the present invention, since the guide plate 30 can be detachably attached to the reaping section 4, the guide plate 30 is positioned above the cutting blade 15, and the rotating shaft cylinder at the rear end of the guide plate I is fixed. The ends of the connecting rod are aligned with the through holes formed in the side plate 19 of the reaping part frame 17, the shaft is inserted from the outside of the side plate 4, and the lower end of the connecting rod is fixed to the guide plate I, When the reel vertical movement cylinder 9 is reduced to lower the tip of the mounting arm B, and the upper end of the connecting rod is attached to the tip of the mounting arm B, the installation of the guide base is completed.

The guide plate 30 is inclined so that it becomes higher toward the rear side, so when the machine moves forward aiming at the accumulated grain culm, the guide root wall slips under the grain culm bundle, and the grain culm bundle moves towards the guide plate. The grain passes over the blade and reaches the auger 16, and is supplied from the auger 16 to the threshing chamber 5 of the threshing device 3 via the conveyor q, where it is threshed.

Furthermore, when the raking reel 14 is placed above the grain culm bundle and the raking reel 14 is rotated, the reel tines n of the raking reel 14 can feed the grain culm bundle to the auger 16, which improves layer efficiency. can be supplied to

In addition, when there are many grain culm bundles, there is a guide plate 3 below the grain culm bundles.
When the scraping reel 14 is moved upward by the reel vertical movement cylinder 9 with the reel 0 sunk in, the tip of the mounting arm B moves upward and pulls the connecting rod A, and the connecting rod A moves to the front end of the guide base. Since the front end of the guide plate 30 rotates around the axis*, the guide root wall is inclined so that the rear side is lower, and the grain culm bundle on the guide plate 30 easily and smoothly reaches the auger 16. The grains are supplied from the auger 16 to the threshing chamber 5 of the threshing device 3 via the conveyor V, and are threshed.

(Effects) Conventionally known Japanese Utility Model Application No. 1-112631 discloses a traveling device provided at a lower position of the fuselage frame, a threshing device provided at an upper position of the fuselage frame, and a threshing device installed at a forward position of the fuselage frame. the reaping section; and a conveyance device provided between the reaping section and the threshing device, the reaping section comprising:
In a combine harvester that has a cutting blade that cuts the roots of grain culms long in the left-right direction and an auger that collects the harvested grain culms provided behind the cutting blade, the upper surface of the cutting blade has a front side of the cutting blade. There is a description of a combine harvester's reaping section, which has guide rods that protrude from the front and touch the ground, and are lower and higher toward the rear at a predetermined interval in the width direction. Grain culms in the vicinity cannot be harvested. Grain culms near the field ridges are harvested by hand with a sickle.
It was collected at the desired location in the field and finally thrown into the auger of the combine harvester.

However, the present invention includes a traveling device 2 provided at a position below the body frame 1, a threshing device 3 provided at a position above the body frame 1, a reaping section 4 provided at a forward position of the body frame 1, and a Reaping section 4 and the threshing gear! The reaping section 4 consists of a cutting blade 15 that reaps grain culms long in the left-right direction, and an auger provided behind the cutting blade 15 that collects the reaped grain culms. 16, on the upper surface of the cutting blade 15, the front side protrudes ahead of the tip of the cutting blade 5, and the front side protrudes in front of the tip of the cutting blade 5, and lowers to the rear side so as to be in contact with the ground. This is the reaping part of a combine harvester equipped with a guide plate I that can move up and down centering on the rear side, so if you aim at the grain culms accumulated at a desired position in the field and plunge into it, the lower guide plate on the front side will move. The grain culm is scooped up by I, guided by the guide plate J which is higher toward the rear side, and fed to the auger 16 for threshing. In this case, since the front side of the guide rice container can be moved up and down centering on the rear side, the rice can be smoothly loaded by occasionally moving the front side up.
