Abstract

PURPOSE:To efficiently carry out sorting of grains while preventing mixing in of long straws in a grain recovery part, by fixing coupling shaft of a rocking arm with a rocking case to a rocking arm mounting plural rack levers on the coupling shaft in a specific state. CONSTITUTION:A coupling shaft 25 for coupling a rocking case 22 with a rocking arm (24c) is fixed to the rocking arm and plural rack levers 26... are mounted on the coupling shaft in the forward direction in an open side state integrally rotatable with the coupling shaft. The rack levers 26... are provided so as to relatively rock to the rocking case with the longitudinal rocking operation of the rocking case and only straws in material to be sorted are received to prevent the long straws from leaking and dropping onto the rocking case.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a threshing machine in which an eccentric cam is provided at the front part of a swinging case equipped with a grain pan and a grain sheave, and the rear part is pivotally connected to a swinging arm. This invention relates to an oscillating sorting device.

[Conventional technology]

Conventionally, the above-mentioned oscillating sorting device has performed grain sorting using only the grain pan and grain sieve.

[Problem that the invention seeks to solve]

However, in the conventional structure described above, if the amount of material to be sorted is large and is fed onto the oscillating sorting device in a thick layer, grains and waste straw cannot be separated sufficiently; There were drawbacks such as the waste straw from the long culms being mixed into the collected grain.

An object of the present invention is to eliminate the above-mentioned drawbacks and to enable efficient grain sorting without long straws being mixed in even when there are many objects to be sorted.

[Means for solving problems]

A feature of the present invention is that, in a rocking sorting device for a threshing machine having a snow raising configuration, a connecting shaft between a rocking arm and a rocking case is fixed to the rocking arm, and a plurality of rack rods are attached to the connecting shaft facing forward. The rack rod is mounted in a cantilevered manner and rotatable integrally with the connecting shaft, and is configured such that the rack rod swings relative to the swing case as the swing case swings back and forth. Its functions and effects are as follows.

[For production]

The swinging case performs a circular motion at the rear end and a back-and-forth rocking motion at the front end, a so-called irregular crank motion. However, since the latch rod can rotate integrally with the connecting shaft, that is, the swinging arm, As it moves, it protrudes above the swinging case to catch only the waste straw from the long culms among the materials to be sorted, and causes grains and small processed materials to leak onto the swinging case. be.

〔Effect of the invention〕

Therefore, even when there is a large amount of material to be sorted, a large amount of long straw is not thrown into the swinging case, and as a result, the grain collection section is not contaminated with long straw, resulting in efficient grain sorting. Now I can do it.

〔Example〕 Embodiments of the present invention will be described below based on the drawings.

FIG. 4 shows a harvester which is an example of a mobile threshing machine equipped with a swing sorting device (1) according to the present invention.

This harvester has a pair of black running gear on the left and right! (2
), a threshing device (4) is removably mounted on the traveling body (3) connected to the machine (2), and a driving unit (
5), and the motive power of this driving portion (5) is transmitted to the crawler traveling devices (2), (2) and the threshing device (4).

The threshing device (4) has a feed chain (
6) and a clamping rail (7) extending in the left and right direction,
The structure is such that the harvested husk is held and conveyed by these, and the granulated part is handled by rotating the handling cylinder (8). The processed material is the handling trunk (8) and the lower catch line (9).
The structure is configured so that the grains are sorted by the oscillating sorting operation (1), which will be described in detail later, and small straw waste is blown upwards at the front by the sorting fan (10), and the dust is removed by the dust exhaust fan (11). ) to carry out the dust out of the machine through the dust outlet (12).

Furthermore, the sorted grains are conveyed to the right side of the threshing device (4) by a flavor recovery screw (13) installed laterally below the oscillating sorting device (1), and then conveyed to the right side of the threshing device (4) by a screw conveyor (14). Bag collection section at the rear of the aircraft (15)
The structure is such that the second paddy such as treated paddy is transported to the right side by a second paddy recovery screw (16) and returned to the handling room by a thrower (not shown).

Said first and second paddy recovery screws (13), (1
6) Below there is a bottom plate that can be artificially slid back and forth (
17), and the bottom plate has long holes (18) and (18) formed in the left-right direction that are located below each screw (13) and (16) when pulled out forward. There is.

As shown in FIGS. 1 and 2, the oscillating sorting device (1
) is a grain pan (1
9) and a grain sheave (20) consisting of a crimp net are arranged in a row in the front and back direction, and rocking plates (21) and (21) are fixed to their left and right ends to form a rocking case (22).
and an eccentric cam (2) at the front of the swing case (22).
3) is attached, and the rear part is equipped with a swinging arm (24), (24
).

The swinging arm (24) is pivotally supported on the body so as to be able to swing freely around the axis (P), and the swinging case (22) and the swinging arm (24) are connected by a connecting shaft (25). has been done. The connecting shaft (25) is fixed to the swing arm (24), and a plurality of rack rods (25) are attached to the connecting shaft (25).
6)... in a forward cantilevered manner, and the connecting shaft (25)
It is installed so that it can be moved in one piece. That is, as shown in FIG. 3, the support part (26a) of the rack rod (26) has an engagement protrusion (27) protruding from the connection shaft (25) that is connected to the support part (26a).
26a) It is fitted onto the connecting shaft (25) in a freely rotatable manner so as to engage with a recess (28) formed inside, and the width (Ll) of the recess (28) is equal to the width of the engaging protrusion (27). ) width (L,
) to suppress the large upward protrusion of the rack rod (26). Further, the upper part of each rack rod (26) is formed in a sawtooth shape so that the long straw is guided to fall from the front end of the device (1) to the second material recovery screw (16).

The rack rod (26)... is swung relative to the oscillating case (22) as the oscillating case (22) swings back and forth, and receives only long straws among the materials to be sorted; This prevents the long straw from leaking onto the swing case (22).
