Description

[Detailed Description of the Invention] The present invention relates to a dust sending device in a threshing machine type waste straw processing machine.

In other words, a sieve line is placed on one side of the handling room where the handling cylinder is installed, and a sieving wire is installed at the lower rear of the dust removal cylinder that rotates in the same direction as the handling cylinder, and a sorting dust removal chamber is installed at the rear of the handling room. In the threshing machine type waste straw processing machine that is installed, this kind of processed material with less paddy and more straw is processed in the handling room and sent from the dust valve to the sorting dust removal room through the dust removal cylinder. When processing, the material to be processed can be scraped up to the dust removal cylinder to be separated and dispersed, allowing for good sorting with the sieve line, and preventing it from forming in clumps and scattering outside the machine due to poor sorting. The present invention is to provide a device that can transport and sort dust well, has a simple structure, and can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Fig. 1 shows a sectional view of this straw disposal machine, in which an input port 10 is installed on the front side of a handling chamber 2 in which a handling barrel 1 with handling teeth 9 is rotatably mounted in the A direction, and an input port 10 is installed on the lower side. A crimp net 11 is stretched around the periphery, and a dust exhaust cylinder 3 having a large number of V-shaped tooth rods 6 on the circumferential surface is installed between the rear part of one side of the handling chamber 2 and the rear sorting dust exhaust chamber 5. A sieve line 4 is installed horizontally at the lower rear side of the dust removal cylinder 3 in the sorting dust removal chamber 5, and Handling room 2 below
The dust feeding control valve 7 is formed into an arc shape and is installed on the rear side of the dust feeding control valve 7, and the supporting shaft 12 inserted into the lower part of the dust feeding control valve 7 is operated by an external operating tool 13 to rotate it. The dust feeding control valve 7 is installed so as to be able to be dynamically locked and to be rotatably adjusted around the support shaft 12. A plurality of protruding rods 8 extending and wrapping between the rods 6 are provided in a comb-teeth shape at intervals in the lateral direction.

Further, a flow grain plate 14 and a swinging sorting plate 15 are installed below the crimp net 11, and the swinging sorting plate 15
A winch 16 and a No. 1 conveyor 17 are installed below, and a No. 2 conveyor 18 is installed below a sorting dust removal chamber 5 equipped with a suction dust exhauster 17 on one upper side.

Therefore, when processing this type of waste straw product that has less paddy and more straw, when it is input from the input port 10, the handling cylinder 1 rotates as shown by arrow A, and the handling teeth 9 crush it in the handling chamber 2. The paddy that leaks through the crimp net 11 is processed by the swinging sorting plate 1.
5, the fine grains are allowed to fall onto the No. 1 conveyor 17 while being air-selected.

The straw waste and paddy with branches and stalks that have reached one side of the handling chamber 2 are guided by the dust control valve 7 as shown by the arrow B and flow toward the dust removal drum 3 side, and then rotate as shown by the arrow C. The toothed rod 6 scrapes the dust and sends it onto the sieve wire 4 as shown by arrow D. In this case, the dust flows from the feed control valve 7 onto the protruding rod 8 and is
It is received by the tooth rod 6, and the tooth rod 6 acts there.
By working together with the protruding rod 8, lumps of straw waste and paddy with stems are scraped off, separated, dispersed, and sent out.

Therefore, it becomes easier to sort on sieve line 4,
This prevents a large amount of paddy from being sucked into the suction dust remover 17 and causing a large amount of No. 3 scattering, and while the dust is discharged outside the machine, the No. 2 paddy falls onto the No. 2 conveyor 18 and is disposed of. It is.

In addition, when the amount of input from the input port 10 is large, operate the operation tool 13 to switch the dust feeding control valve 7 to the fifth position.
As shown by the arrow H in the figure, it is rotated rearward to the state shown by the imaginary line to increase the amount of dust sent from one side of the handling chamber 2 to the sorting and dust removal chamber 5. The protruding rod 8 becomes almost perpendicular to the rotation locus, and the amount of wrap increases from M amount to L amount, and as the amount of dust fed increases, the tooth rod 6 and the protruding rod 8 become more The action is increased and the scraping action by the tooth rod 6 is enhanced for processing.

In this way, the present invention has a sieving line placed on one side of the handling chamber housing the handling cylinder that rotates in the direction A, and a sieve line on the lower rear side of the dust removal cylinder that rotates in the same direction as the handling cylinder. In a threshing machine-type straw processing machine that is equipped with a sorting and dust removal chamber at the rear of the handling chamber, there is a dust feeder installed at the rear of the handling chamber at the lower front side of the dust removal cylinder that has tooth rods on the circumference. A control valve is installed so as to be rotatably adjustable, and a plurality of protruding rods are provided at the upper end of the dust-feeding control valve in a comb-teeth shape to intersect with and wrap around the rotation locus of the toothed rod toward the dust exhaust cylinder. Moreover, when the dust feeding control valve is rotated rearward, the tip of the protruding rod approaches the circumferential surface of the dust exhaust cylinder, increasing the amount of wrap, so that there is less paddy and less straw. A large amount of waste straw is processed in the handling chamber and guided toward the dust exhaust cylinder by the dust control valve and the protruding rod protruding from its upper end. The tooth rod acts as if it were scraping, dispersing it and sending it onto the sieve line, allowing it to be sorted in the best condition by the sieve line. There is no scattering. Moreover, as the amount of dust sent is increased by operating the dust feeding control valve, the protruding rod becomes almost orthogonal to the rotation locus of the tooth rod, and the amount of lapping increases, causing the scraping by the tooth rod. This increases the amount of dust, thereby increasing the synergistic action with the protruding rod and increasing the scraping action of the dust, so that the dust is always reliably fed and sorted according to the adjustment operation of the dust feed amount. It has the advantage that it can be easily implemented with a simple structure.
