JPS5850844Y2 - Grain outlet shutter device - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to an improvement of a grain outlet shutter device for opening and closing a grain outlet in a combine harvester or the like.

Conventionally, in this type of shutter device, both side edges of a plate-shaped shutter with parallel side edges are slidably supported in grooves formed between a shutter guide and a support plate. As shown in FIG. 6, the grooves were formed in parallel to the side edges of the shutter.

For this reason, dirt and the like were clogged between the side edge of the shutter and the groove, making it difficult for the shutter to operate smoothly.

In the present invention, by providing an appropriate relief part between the middle part of the groove part and the shutter side edge, dust etc. that have entered between the shutter side edge and the groove part are collected in this gap part, and the shutter operation is prevented. The aim is to ensure that the process runs smoothly.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In Figures 1 to 5, 1 is a reaping section provided at the front of the combine, 3 is a threshing section that threshes the husk cut off in the reaping section 1, 5 is a pilot's seat, 7 is an engine, and 9 is a It is a traveling device.

11.13 is a hopper arranged in parallel on the side of the threshing section 3;
Reference numeral 5 denotes a grain lifting device that transports the threshed paddy from the threshing section 3 to the hoppers 11 and 13.

17.17... is a plate-shaped shutter that opens and closes the discharge ports 19, 21.23 at the bottom of the hopper 11.13,
A shutter guide 25 slidably supports the shutter 17. A groove 31 is formed between the shutter guide 25 and the support plate 29 fixed to the discharge tube 27, and the side edge 33 of the shutter 17 is slidably fitted into the shutter guide. There is.

35 is a spacer held between the shutter guide 25 and the support plate 29, and forms a side wall 37 of the groove portion 31.

39, 39, . . . are bolts that fix the shutter guide 25 and the support plate 29 through the spacer 35.

41 is a relief portion provided between the side edge portion 33 of the shutter 17 and the spacer 35 in the middle portion of the groove portion 31;
45 is the shutter 17. These are openings provided in each of the shutter guides 25.

In the above configuration, the husks cut by the reaping section 1 are threshed in the threshing section 3, and the threshed paddy is conveyed by the hoisting device 15 and enters the hopper 11.13,
The air is discharged and filled into a storage bag (not shown) through the air outlet 19, 21.23 and the discharge tube 27°27.27.

Operate the shutter 17.17.17 to open the discharge port 19.
It opens and closes 21.23.

When the shutter 17 slides, dirt or the like that enters between the side edge 33 of the shutter 17 and the groove 31 enters the relief part 41 as the shutter 17 slides, thereby interfering with the sliding movement. Never.

Note that FIG. 6 shows a conventional configuration, and the same reference numerals as in FIGS. 1 to 5 indicate the same components.

As described above, the present invention provides a shutter device for opening and closing a discharge port, in which a groove portion that slidably supports a side edge portion of the shutter is provided, and in an intermediate portion of the groove portion, the side edge portion of the shutter and the groove portion This grain outlet shutter device has a relief part between the side wall of the shutter and the shutter that allows the shutter to move when paddy is caught, so when paddy etc. is caught between the shutter and the side edge of the shutter, The bitten paddy is crushed and escapes into the escape section with the movement of the shutter.

Therefore, crushed rice grains and the like are less likely to get stuck between the side edge of the shutter and the groove, and the shutter can operate smoothly.
