Abstract

PURPOSE:To surely cut a lodged culm without leaving uncut culm by scooping a lodged culm with each scooping and guiding member and raking up with a reel tine. CONSTITUTION:The tip end of each stationary receiving edge 7 is extended downward toward the front and is provided with a scooping and guiding member 8 inclined upward toward the back while placing the rear end above a mobile cutting edge (b). The tine 3a of the raking reel 3 to rake up a standing culm toward the reaping apparatus has a locus (k) intruding between the scooping and guiding members 8. A standing culm is passed between the scooping and guiding members 8 and guided backward according to the forward motion of the machine body. On the other hand, a lodged culm is scooped up with the tip end of each scooping and guiding member 8, guided upward along the guiding face inclined forward and erected from the root. At the same time, the culm is surely raked up with the tine 3a of the rake-up reel 3 and introduced into a reaping apparatus.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a reaping device mainly used in a conventional combine harvester equipped with a raking rule.

Prior Art and Problems Conventional general clipper-type reaping devices do not provide sufficient raking action when the shell culm is extremely lodging. They simply passed over the top of the culm, resulting in a large number of uncut leaves.

The present invention enables even extremely lodging culms to be harvested before being harvested.
This is intended to solve the above-mentioned problem of uncut mowing by raising the cut material while scooping it up in advance with a scooping guide and then reliably scooping it up with a scooping reel.

Means for Solving the Problems Therefore, the present invention has provided the following technical means. That is, in a reaping device consisting of a movable cutting blade body 6 that reciprocates in the left-right and lateral directions, and fixed blade receivers 7 arranged at predetermined intervals in the width direction, the tip of each fixed blade receiver 7 is A scooping guide 8 is provided which extends downward in the front direction and is inclined upward and rearward from the distal end thereof, and whose rear end faces above the movable cutting blade body to cut the erect culm. This invention is characterized in that the tine locus of the scraping rule that scrapes up toward the apparatus side is configured to intervene between each of the scooping guides.

Operation According to the above configuration, the erect piloere culm is guided to the rear side through the space between the scooping guides 8 as the aircraft moves forward, but at this time,
The lodging culm is scooped up by the tip of each scooping guide 8 and erected from the base of the stock while being guided along the rearward and upwardly inclined guide surface, and is also lifted up by the tine 3a of the scooping reel 3. The material is reliably raked up, introduced into the reaping device, and cut.

Effects of the Invention Therefore, according to the present invention, even if the culm is extremely lodging, it can be scooped up by each scooping guide and further raked up by the reel tines, so that it can be reliably cut without leaving anything uncut. be able to.

Example An embodiment of the present invention will be described below based on the drawings.

A reaping pre-processing section B for supplying cut husk culms to the threshing section A is provided in front of a threshing section A mounted on a chassis equipped with running rollers 1.

The reaping pre-processing section B includes a weeding tool 2 that divides the erect culms into objects to be reaped and objects not to be reaped, and a weeding tool 2 to apply a raking action to the culms to be reaped by tines 3a while rotating toward the rear of the machine. The raking reel 3, the reaping device 4 that cuts the culm in the raked state, and the cross-feeding auger 5 that moves the culm to the left and right center and sends it out to the rear of the machine. Furthermore, it is configured to include a feeder for conveying and supplying the husk from the auger 5 to the threshing section.

The reaping device 4 is composed of an upper movable cutting blade body 6 and lower fixed blade receivers 7 arranged at predetermined intervals in the width direction, and the tip of each fixed blade receiver 7 is moved forward and downward. It has a restraining inclined guide surface 8a that extends toward the front end and slopes rearward and upward from the tip thereof, and is raised rearward and upward to a position where the rear end faces above the movable cutting blade body 6. A scooping guide 8 that extends is provided. By making the height H from the movable cutting blade 6 to the upper surface of the rear end of the scooping guide 8 higher than the distance between the fixed receiving blades 7, 7, a broken culm shorter than the distance can also be movable. There is no chance of being cut by the cutting blade body 6.

Further, K indicates the locus for lifting up the tip of the reel tine 3a, and the tine 3a is provided in a state of wrapping in a side view so as to intervene between each scooping guide 8, 8.

[Brief explanation of the drawing]

The figures show one embodiment of the present invention, in which Fig. 1 is a side view of the main parts of the combine, Fig. 2 is a side view of the main parts, and Fig. 3 is a plan view of a part thereof. . 3 is a rake reel, 3a is a tine, 4 is a reaping device, 6 is a movable cutting blade body, 7 is a fixed blade receiving body, and 8 is a scooping guide.

Claims (1)

[Claims] In a reaping device consisting of a movable cutting blade body 6 that reciprocates in the left and right horizontal directions and fixed blade receivers 7 arranged at predetermined intervals in the width direction, the tip of each fixed blade receiver 7 is moved forward and downward. A scooping guide 8 is provided at its distal end, which is inclined rearward and upward from this, and whose rear end faces above the movable cutting blade body, so as to direct the upright culm toward the cutting device. 1. A reaping device characterized in that a tine locus of a rake reel that rake toward the target is configured to intervene between each of the scooping guides.
