Description

[Detailed description of the invention] Industrial applications TECHNICAL FIELD This invention relates to a control dust control device for a combine harvester.

PRIOR ART AND PROBLEMS TO BE SOLVED BY THE INVENTION Conventionally, in the Funpine, etc., where grain culms are harvested and threshed at the same time, the moisture content of the grain culms is reduced to a permissible range that can be threshed by the threshing device, that is, A44. - Generally speaking, harvesting is carried out when the leaves and stems are slightly withered, so during the harvesting process, a large amount of dust is generated from the reaping equipment and threshing equipment, and the operator is exposed to this dust. The operator is forced to carry out the work and is forced to work very hard, but currently, from an economic standpoint, there are not many measures taken to protect the operator from this dust.

Therefore, the present invention aims to protect the operator from dust as much as possible and improve the comfort of the vehicle in consideration of economic efficiency.

Means for Solving the Problems This invention provides a harvested grain culm transfer bag 2 which transports and supplies the grain culm harvested by the front reaping bag 211 (1) to the rear threshing device (2)! (3) and the control platform (9) on the lateral side of the transfer bag 21 (3), with the upper part of the control platform (9) directed toward the side opposite to the transfer device (3) side. Wind blowing duct (6
) is the structure of the combine operation dust prevention device.

Functions and Effects of the Invention During harvesting work using a combine harvester, etc., the work is carried out with the stems and leaves of the grain culm being slightly withered. ) and the grain culms are threshed! (2)
A large amount of dust is generated during the process of threshing, etc., but the blow duct (6) installed between the transfer device (3) and the control platform (9), for example,
) is sprayed upward from the control platform (9) on the side opposite to the transfer device (3) to block dust and protect the operator from dust. It protects against

In this way, each device (1
) (2) The dust generated from (3) is transferred to the transfer device (3).
The upward direction of the control stand (9) from the blower duct (6) provided between the control stand (9) and the control stand (9) can be appropriately blocked by the jet in the form of an air curtain.
In particular, the comfort of the operator can be further improved in a simple and economical manner without providing a cabin or the like for the operator.

Embodiment In the illustrated example, an endless body (11) (1

Reaped grain culm transfer device for transporting grain culms to the threshing device (2)! ! ! (3
) are connected to each other, and the threshing device (2) for threshing grain culms is connected to the rear of this transfer device (3). In addition, each device (1) (2) is placed on the front end of the right side of the traveling device (12) in a position approximately parallel to the transfer device (3).
(3) A control platform (9) for operating (12) is provided adjacent to the transfer device (3), and this control platform (9)
A cockpit (4) is provided adjacent to the threshing machine (2) behind the threshing machine (2), and the lower part of the cockpit (4) has six! ! 1 (1)
(2) The prime mover for interlocking driving of (3) and (12) (
13), and a grain collection tank (14) 4 adjacent to the rear side of the driver's seat (4) and the prime mover (13) for storing the grains threshed by the threshing device (2) into a grain storage bag. The threshing device (2) is connected to the grain collecting tank (14).
A grain lifting cylinder (for lifting and transporting grains threshed by
15) is provided with its lower end connected to the threshing device (2) and its upper end connected to the grain collecting tank (14).

A partition wall (5) having a height that can cover an appropriate height of the operator is installed between the transfer device i1 (3) and the cockpit (4).
) is connected and fixed at the front end side to the left end of the cockpit (9), and the cockpit (4) is inserted from the front edge (17) which is arbitrarily tilted rearward toward the upper edge (1B) of the cockpit (4). ) is arranged in a cross-shaped shape in plan view, and the rear end side part is connected and fixed to the grain collection tank (14). Also, the partition wall (5)
A spout formed with an arbitrary height and width from the front edge (+7) to the L-shaped upper edge (1B) from the partition wall (5) toward the cockpit (4) side. A wind duct (6) is provided protrudingly, and the blower duct (6) is provided on the rear side of the cockpit (4).
) A suction and exhaust fan (7) for blowing air to the blower duct (6) is provided to protrude further rearward from the portion, and the suction port (8) of this suction and exhaust fan (7) is connected to the cockpit (4). ) The cockpit seat (4) in order to simultaneously suck in dust floating around the upper part of the rear side.
The blower duct (6) on the rear side is opened to extend downward by an arbitrary length. In addition, between the pulley (1B) provided on the outer upper part of the suction exhaust air a (7) and the pulley (19) provided at the upper end of the grain lifting cylinder (15), Transmission bell for transmitting power to the suction exhaust fan (7) side)
(20) is stretched. A blower port (21) for blowing air in an air curtain state from the blower duct (6) to the upper side of the transfer device (3) is provided on a line along the upper edge (16) over a possible width. At the same time, a blower opening (22) that blows air from the blower duct (6) to the upper side of the control platform (9) in an air curtain state is installed in a line along the front edge (17) to a width within the possible range. Provided across. The partition wall (5) is equipped with 6 equipment for the pilot from the cockpit (4)! 1 (1) (2)
