Abstract

PURPOSE:To expand an adaptive range of threshing and improve threshing performance and efficiency, by enabling a change of dust conveying guides into a larger tilt angle than that of beltlike flat protruding units in the conveying direction on a threshing drum. CONSTITUTION:Beltlike flat protruding units 10 intermittently protruding at a prescribed internal in the screw direction and threshing teeth protruding from the outer peripheral part thereof are provided on the outer periphery of a threshing drum 6 of an axial flow type thresher for charging the total amount of reaped grain culms thereinto. Dust conveying guides 12 are provided on the inner peripheral wall part of the threshing chamber so that the tilt angle can be changed. If the guides 12 are tilted to a larger tilt angle (theta2) than the that (theta1) in the conveying direction of the protruding units 10 by operation of an operating lever 15, treating action is increased. If the guides 12 are tilted to a tilt angle (theta3) on the conveying side, treatment in a large quantity can be carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to harvested grain I? This relates to an axial flow type threshing device that supplies the entire amount of grain into a handling chamber and threshes the grain while transferring it in the axial direction of the handling barrel.

Prior Art and Problems Conventionally, in this type of axial flow type threshing device, the spiral handling cylinder
Since the spiral around the outer circumference of the handling cylinder is continuous, the feeding action of the spiral is greater than that of the dust guide, and the inclination angle of the spiral (
The feed in the handling room was easily influenced by the grain size (or pitch), and the range of threshing adaptation was small.The present invention aims to widen the range of adaptation and improve threshing performance and 1M rate. The following technical measures were requested.

Means for solving the problem, that is, the technical means according to the present invention is an axial flow type threshing device that supplies the entire amount of harvested culms into a handling chamber and threshes the grain while transferring it in the axial direction of the handling cylinder 6. In this, the outer periphery of the handling cylinder is provided with a belt-shaped flat protrusion 10 that continuously projects at predetermined intervals along the virtual spiral direction, and handling teeth 11 that project from the outer periphery to the external force. On the inner circumferential wall of the handling chamber 5 corresponding to It is characterized by certain things.

Effects of the Invention Therefore, according to the present invention, the inclination angle of the dust guide can be changed to a position larger than the inclination angle in the feeding direction of each strip-like flat protrusion for newspapers. , when the dust feeding guide 12 is tilted more towards the resistance side than the feeding direction inclination angle 08 of the belt-shaped flat protrusion 10 by Oj,
Each strip 0. The space between the IqL protrusions 10.10 makes it easier for the grain to be threshed to move in the opposite direction against the feed, increasing processing action and reducing loss. In addition, even if the dust feeding guide is tilted in the opposite direction to the above, that is, by 03 toward the feeding side, the grains to be threshed tend to move more in the feeding direction than the spaced portions beyond the feeding action of the belt-like flat protrusion, and a large amount This has made it possible to process husks, expanding the scope of threshing applications, and significantly improving husking performance and efficiency.

EXAMPLE Hereinafter, one embodiment of the present invention will be explained based on the drawings.The axial-flow type decompression equipment shown in Figure 0 has the following configuration. That is, a receiving chamber 5 is provided along the lower half circumference, the upper part is covered by a cover 2, a supply 113 is provided on the front side, and a JJ+: outlet 14 is provided on the rear side, and the handling chamber It consists of 6 handling cylinders with internal shaft racks. A conical part 6a is formed in the front part of the handling barrel 6, and a receiving plate 7 for the person 11 is provided at the lower corresponding part of the conical part 6a and tilts diagonally forward and downward.
A feeder 8 is installed near the receiving plate 7 of the man 11 to supply the entire amount of the harvested culms.

Then, on the outer circumferential surface of JIAG marked 11q, there is written jI1
In the part of the conical part 6a on the first side of 1N, a continuous spiral feed 9 that does not change the handling tooth angle is provided by winding, but within a range extending from this to the terminal side, it protrudes intermittently along the virtual spiral direction. The belt-shaped flat protrusions 10 are configured to protrude at three equal intervals at predetermined intervals in the circumferential direction.

Each band-shaped flat protruding body 10 is provided with a radial tooth 11 that slightly protrudes outward from the outer peripheral edge.

``)'' The inner wall of the cover 2 that covers the upper part of the storage cylinder 6 has an inclination angle that can be adjusted in the feeding direction and in the counter-feeding direction (feeding resistance direction) with respect to the feeding direction inclination angle O8 of the belt-shaped flat protrusion. Twelve dust feeding guides 12 are installed.

In other words, this dust feeding guide 12 is pivoted 13 at one end to the cover 2, and pivoted at the other end to a connecting rod 14, and is operated by an operating lever 15. The angle of inclination 03 promotes the feed and the brake is attached to this feed.
It is designed so that 51 arbitrary changes can be made over the range of the inclination angle 03.

The cut culm from the cutting section enters through the feeder 8 11
The entire amount of Uke is put on board 7, but y:! The culm is fed into the handling chamber 5 by the spiral feeder 9 at the starting end of the handling cylinder 6 and is further transported toward the rear. Coupled with the feeding action by the body 10, the band-like flat protruding body 100 and the radiation plate fi11 effectively act to receive stirring and beating action, and also between the dust feeding guide 12 including the receiving net 1 on the periphery of the handling chamber. The grain undergoes a full-scale threshing process.

Then, the threshed grains, etc. leak from the receiving net 1 to the lower sorting section 16, and the threshed culms, such as RTl, are removed.

It is discharged to the outside from the discharge port 4.
