Description

[Detailed description of the invention] Conventional threshing machines often have a dust sorting room at the rear of the handling room, that is, at the end of the feed chain.
In that case, since the dust ejector is installed at a relatively upper position in the ejector dust sorting room, its transmission device is located above the first and second transfer spirals located at the bottom of the machine, and at the end of the feed chain. In addition, a large amount of debris such as straw and weeds is brought in and falls at the end circulation part of the feed chain, and it gets wrapped around the transmission device of the dust extractor, the intermediate pulley, and the belt wrapped around it. There were some drawbacks.

The purpose of the present invention is to improve the above-mentioned drawbacks, and the present invention is to install an under-type feed chain 2 along the handling opening on the side of the handling chamber, and to attach a transmission device to the terminal end of the feed chain. In the threshing machine, the feed chain 2 and the transmission device are covered with a cover, the cover covering the outside of the feed chain is extended downward from the feed chain to form an opening at the lower end, and the terminal end of the feed chain and the transmission mechanism are connected to each other. The present invention is characterized in that a guide partition is provided between the feed chain and the guide partition that slopes downward toward the starting end of the feed chain and faces the opening.

The embodiments shown in the drawings will be explained below.
Reference numeral 1 refers to the side wall on the handling port side of the threshing machine. is approximately T-shaped.

Reference numeral 2 is an under type feed chain stretched along the lower edge of the handling port, and a pinch rail 3 is provided oppositely on the upper surface of the feed chain 2, and is placed at an appropriate distance from the end of the feed chain 2. A suction-type dust-exhaust winch 4 is provided.

Further, on the outside of the inwardly recessed portion below the side wall 1, a pulley 5 of the pressure karate, a pulley 6 of the first transfer spiral, a pulley 7 of the second transfer spiral, etc. are pivotally supported, and these are supported by the belt 8. , 9 and an intermediate pulley 10 by the handling cylinder shaft.

Then, from the feed chain 2 to the dust removal kiosk 4
The outer surface of the transmission device, which will be described later, is covered with an upper cover 11 extending downward from the feed chain 2, and the portion where the lower pulleys 5, 6, and 7 are provided is covered with a lower cover 12. From the part X near the end of the lower edge of the upper cover 11 on the supply port side to the lower part Y of the end of the feed chain 2
The opening 11a is opened as shown in FIG.
It is closed in close contact with the

Further, an upper-type straw removal chain 13 and a straw removal belt (not shown) for conveying the tip side of the straw removal chain 13 are continuously provided from the end of the feed chain 2 to the top plate 12' of the dust sorting chamber.

Further, a portion of the upper edge of the lower cover 12 facing the opening 11a is bent toward the side wall 1 to form an inclined guide surface 12a, and the upper edge thereof is bent toward the side wall 1 to form an inclined guide surface 12a. It faces directly below the lower end, and the interior of the area between Y and H rearward from the terminal end of the inclined guide surface 12a communicates with the upper cover 11, as shown in FIG.

14 is located between the upper cover 11 and the side wall 1 along the return side of the terminal end circulation part of the feed chain 2 and is inclined downwardly toward the starting end side, and includes the intermediate pulley 10 and a part of the belt 8 wrapped around it; It is a guide bulkhead that faces the end of the opening 11a through the upper surface of a transmission device such as a belt that transmits the power to the dust removal winnower 4, and its edge on the side wall 1 side is connected to the drive shaft 2a of the feed chain 2 as shown in FIG. It is received by the inner side of the rib 15a of the reinforcing plate 15, which is cut out at the portion through which the reinforcing plate 15 passes.

In the above-mentioned apparatus, when the ears are inserted into the handling chamber through the supply port and the stock part of the grain culm is conveyed between the feed chain 2 and the pinch rail 3 for threshing processing, the side wall 1 and the upper cover are removed from the feed chain 2. The straw, mud, etc. that have fallen between the upper cover 11 and the side wall 1 pass through the opening 11a and fall onto the inclined guide surface 12a of the lower cover 12, and are sent to the outside of the lower cover 12. slide down to

At the end of the feed chain 2, the straw stock part is connected to the straw removal chain 13 and the guide rail 13a.
The ears are transferred between the straw removal belt and the guide rod facing the straw removal belt, and are further conveyed and discharged.

At that time, a large amount of straw waste mixed with some long straw is scraped off or brought in at the end circulation part of the feed chain 2, but these straw waste etc. The opening 11 is scraped out and slid down by the rotation of the opening 11.
Since it is discharged to the outside from a, the intermediate pulley 10
It also prevents straw from wrapping around the transmission device such as the belt that transmits the dust to the dust removal winnower 4, and also prevents the straw from getting wrapped around the lower transmission mechanism or being sucked into the pressure winnower, reducing the sorting efficiency. It can be prevented.

As mentioned above, the present invention is a threshing machine in which an under-type feed chain 2 is stretched along the handling opening on the side of the handling chamber, and a transmission device is attached to the terminal end of the feed chain. A cover that covers the outside of the feed chain is extended downward from the feed chain to form an opening at the lower end, and is provided between the terminal end of the feed chain and the transmission mechanism and descends toward the starting end of the feed chain. Since the guide bulkhead is inclined and faces the opening, a lot of straw waste is brought in or falls at the terminal circulation part of the under type feed chain, but the guide bulkhead is close to the lower part of the terminal end of the feed chain. It is possible to reliably prevent the brought-in straw waste from wrapping around the transmission device by obliquely detouring around and covering the transmission device.

In addition, straw debris, etc. that has fallen onto the guide bulkhead is scraped off during the return stroke of the feed chain's terminal circulation section, and is also slid down and discharged toward the opening by the inclined surface, thereby preventing clogging with straw debris, etc. .
