Description

[Detailed description of the invention] This invention uses a device to transport the grain from the reaping section to the threshing section.
This invention relates to a dust-proof structure for a combine harvester, in which the culm is configured to change its posture from an upright position to a collapsed position facing in the lateral direction of the machine body, and a control section is disposed on the side of the culm in the tip direction.

Conventionally, the cover that covers the device that transports the harvested husk from the reaping section to the threshing section has been integrated, which prevents clogging of straw on the tip side of the transport device and mud clogging on the stock side. When removing the cover to deal with this problem, the entire cover must be removed even if either the tip side or the stock side is to be repaired, resulting in low work efficiency.

In view of these circumstances, the purpose of the present invention is to simplify the work of opening and closing the cover itself, and also to enable the cover to be opened and closed in a state appropriate to the occurrence of trouble, and to make repair inspections easier as a whole. .

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

A reaping section 4 consisting of a planted culm lifting device 2 and a reaping device 3, and a reaped culm conveying device consisting of an ear tip conveying section 5a and a stock base conveying section 5b are installed on the front part of the machine body equipped with the crawler traveling device 1. 5 is provided, the planted culm is pulled up for reaping, and the attitude of the reaped culm is changed from an upright position to a fallen position facing in the direction of the lateral force of the aircraft by cooperation of the ear tip conveying section 5a and the stock base conveying section 5b. It is composed.

A threshing section 6 is mounted in the center of the machine body, and the horizontally fallen shell culm is taken over by a feed chain 7 and supplied to the threshing section 6,
It is configured to perform the threshing process and to transfer the threshed grains to the bagging section 13.

A device for shredding the threshing section straw is installed at the rear of the machine, and the threshing section straw is shredded and discharged outside the machine.

A control section 8 is provided on the lateral side of the cut husk conveying device 5 at the front of the machine to configure a combine harvester.

The upper and lower parts of the reaping section 4 are integrally connected to the threshing section 6 by connecting devices 9.9, and the conveying device 5 is also supported by the connecting device 9. are connected together.

A threshing section 6 is pivotally connected to the traveling device 1 so as to be rotatable around a horizontal axis X□, and a hydraulic cylinder 10 is inserted between these two 1 and 6, and by the expansion and contraction of this cylinder 10, the threshing section 6 is arranged to drive and oscillate around the horizontal axis X1 with respect to the traveling device 1, thereby making it possible to change the cutting height by changing the height of the cutting section relative to the ground.

The left and right cover portions 11 and 12 of a cross-section type are pivotally connected to the connector 9 so as to be rotatable about the center of the entire cover, and their downward rotation is prevented by a stopper. In such a state, when the conveying device 5 is arranged to cover the upper part and the sides thereof and the culm is conveyed from the standing position to the sideways position, the culm is transported from the tip of the culm. It suppresses the scattering of wood grains etc. blown back from the shell culm supply port 6a to the cutting and threshing device 6 into the control section 8, and further prevents the mud etc. adhering to the stock base from scattering to the uncut shell culms. It should be suppressed.

Furthermore, in order to remove clogging such as wood from the tip conveying section 5a of the conveying device 5, only a portion 12 of the tip side cover is swung open, and on the other hand, clogging such as mud from the stock conveying section 5b can be removed. To lubricate, it is necessary to open only the part 11 of the stock side cover, that is, the area where sufficient maintenance can be done, and by opening only the necessary parts, work such as removing blockages etc. can be done quickly. be.

The cover portion 11 has an upper plate 11a and a side plate 11b which are pivotally connected to each other so as to be relatively rotatable around an axis along the shell culm conveying direction, and can be folded when the cover portion 11 is rotated upward. It is designed to be compact in its open state.

Note that the same structure is also adopted for the cover portion 12.

Further, it is preferable to provide a transparent viewing window in each cover portion 11, 12 so that trouble occurrence can be monitored from outside the cover.

In other words, in the dust-proof structure of the combine described at the beginning, the present invention provides a dust-proof cover that covers the upper and side parts of the husk transfer path from the reaping section to the threshing section, and the left and right portions of the dust-proof cover cover the axis along the culm conveying direction. The upper plates 11a and 12a and the side plates 11b and 12b of the left and right parts 11 and 12 are connected so as to be relatively rotatable around an axis along the culm transport direction. characterized by things.

In other words, since half of the cover can be opened and closed by a swinging operation, the opening and closing operations themselves can be performed more easily than by means of removing the cover.Furthermore, the left and right parts of the cover can be opened and closed independently, respectively, on the axis along the culm transport direction. Since the cover can be opened and closed around the core, it is possible to open and close the cover in a state that is suitable for troubles that occur uniquely on the tip side and stock side, making it easier to carry out repairs and inspections as a whole.

Furthermore, in the present invention, the left and right cover portions 11 and 12 are constructed with separate covers that cover the upper and lateral sides of the culm transport route, that is, the upper plates 11a and 12a and the side plates 11b and 12b,
Moreover, since both plates are connected to each other so that they can rotate freely, the area around the culm transfer route can be opened wide from top to bottom, which not only makes it easier to open and close the cover, but also contributes to improving the efficiency of repair and inspection work. It has a dust-proof structure that is advantageous in practice.
