Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a threshing machine for threshing rice, wheat, etc.

(Conventional technology) It had a rotating body installed above it.

However, according to this configuration, since there is no dust extractor in the vicinity of the processing material processed by the rotary drum, most of the waste material gets mixed into the second material and is sent to the lower second material. It fell into the transport spiral and became the second object.

As a result, there was a fatal defect in that the second transfer spiral for processing the second grain and the second grain lifting machine following it could become clogged.

[Problems that the invention attempts to solve]

This invention aims to solve the above-mentioned defects of the conventional device, and aims to prevent as much straw waste, dust, etc. from being mixed into the second material falling into the second transport spiral. .

[Means to solve the problem]

The present invention takes the following technical means to achieve the above object. That is, there is a handling chamber 2 in which the handling barrel 1 is mounted on an internal shaft to perform the threshing process, a pressure winch 3, a first transfer spiral 4, and a second transfer spiral 5, which are arranged in this order, and above which is a swing sorting device. 6, a rotary drum 8 which is pivoted above the second transfer spiral 5 in a direction orthogonal to the handling drum 1, and a suction dust remover 9 provided close to the rotary drum 8. It is.

〔Example〕

In the handling chamber 2, a handle 11111 having handle teeth 10 is mounted on an internal shaft.

A receiving net 11 is stretched around the outer periphery and the leg portion of the handling trunk 1.

and,! ! The separate room 7 is arranged rearward from the bottom of the handling room 2, and is provided in the order from the front low part to the air pressure kettle 3, the first transfer spiral 4, and the second transfer spiral 5, and above these is a swinging sorting bag f.
f16 is provided so as to be swingable.

The sorting air passage 12 has a starting end communicating with the air pressure winch 3,
It is branched from the middle part so that one 12a passes through the inside of the swing sorting device 6, and the other 12b passes over the first transfer spiral 4 and passes over the second transfer spiral 5.

The rotating drum 8 has a large number of loosening tools 13 installed in the radial direction on its outer periphery, and is positioned diagonally above the second transfer spiral 5 and above the swinging sorting device 6, and is arranged to perform the above-mentioned handling. It is mounted on a shaft perpendicular to the trunk 1.

The suction dust ejector 9 is located on the side of the machine body at a position close to the above-mentioned rotary drum 8, and is configured to suction and remove dust.

14 is a feed chain, which is provided along the handling chamber 2. 15 indicates a clamping rod, and 16 indicates a straw removal chain.

Next, its effect will be explained.

Each rotating part of the machine body is driven to clamp the shell culm between the feed chain 14 and the clamping rod 15 and feed it to the handling room 2.

Then, the husk is threshed by the rotating handling drum 1, becomes waste straw, is transferred to the straw removal chain 16, and is discharged outside the machine.

On the other hand, the threshed grains leak into the lower sorting chamber 7 from the receiving net 11 on the outer periphery, are subjected to shaking action and wind selection action, and are collected into the lowermost transfer spiral 4.

Moreover, the treated material that did not leak from the receiving net 11.

It falls from the end of the handling chamber 2 onto the swinging sorting device 6 below and is subjected to sorting action. .

In this way, the processed material reaches the sorting chamber 7.

The oscillating sorting device 6 uses the oscillating motion and the sorting wind from below to sort out mixed grains, culms to which grains are attached, straw waste, etc. , still being transported to the rear.

The unprocessed material transferred on the swing sorting device 6 reaches the rotating rotary drum 8, where it is beaten and loosened, and the mixed grains are separated from the straw waste. be done.

The materials processed by the rotary drum 8 are further subjected to wind separation, and the second material falls into the second transfer spiral 5 below, and the waste material is transferred to the suction dust ejector 9 located nearby. The dust is sucked into the dust.

〔effect〕

In this invention, since the suction dust remover is located close to the rotary cylinder, the dust generated on the discharge side of the rotary cylinder can be immediately sucked and removed.

Therefore, it is possible to reduce the amount of dust mixed into the second grain grain, and to minimize clogging of the second grain transfer spiral and the second grain lifting device.
