Abstract: PROBLEM TO BE SOLVED: To readily confirm the position of an implement, etc., relatively to an object by visual check from a boarding and alighting port of a cabin. SOLUTION: A structure for opening and closing a door comprises the sliding door 49 slidably composed over a front closing position for closing the boarding and alighting port 40 formed in the transverse lateral part of the cabin 9 covering a boarding driving part 8 and a rear full opening position greatly opening the boarding and alighting port 40. The front side of the sliding door 49 is supported with a pair of upper and lower shaking arms 67 and 69 shaking the front side of the sliding door 49 to the front and rear. The rear side of the sliding door 49 is supported with a sliding member 71 sliding along a guide rail 72 directed to the front and rear and composed so that the front end of the sliding door 49 describes a circular arc track K1 and the rear end of the sliding door 49 describes a straight-line track K2 during opening and closing of the sliding door 49. The front end of the sliding door 49 is composed so as not to overhang from the extension ends of grass diving guides 14 guiding plant stand grain culms to the lateral outside of the machine body to lateral outside of the machine body.

Abstract: PROBLEM TO BE SOLVED: To provide an operative structure for a working machine intended to mitigate the feeling of fatigue given to an operator as a result of steering a traveling machine body or making a lift operation for a working unit, and ensuring such a delicate operation to be made easily. SOLUTION: This operative structure for a working machine has the following mechanism: a traveling machine body 2 is steered by a steering system 33 through making a changeover of the actuation mode of left and right crawler- type traveling units 1 and the lift mode of a working unit 3 linked to the traveling machine body 2 is put to changeover by the action of a lift unit 35 based on the back-and-forth swing operation of a control lever 15; wherein the traveling machine body 2 is steered by the steering system 33 through making a changeover of the actuation mode of the left and right crawler-type traveling units 1 based on the operation, in the transverse direction, of a finger-acting operative tool 70 equipped with the control lever 15, and the lift mode of the working unit 3 linked to the traveling machine body 2 is put to changeover by the action of the lift unit 35 also based on the operation, in the vertical direction, of the operative tool 70.

IPC: B62D11/08
Abstract: PROBLEM TO BE SOLVED: To provide a steering device of an agricultural working machine capable of steering and operating a machine body at a different turning mode by a simple and light operation. SOLUTION: When a steering lever 42 is pivoted and operated to any one of the right and left sides from a neutral position, a steering control means 43 operates an electric motor 110 based on an information from a sensor 49 and a steering switch valve V1 is switch-operated by the electric motor 110 to operate one of side clutches 20L, 20R to the disconnection side. At this time, a turning mode selection valve V2 operates a clutch C to the connection side and a traveling device on the turning inside is speed-reduced. When the steering lever 42 is further oscillation operated in this direction, the steering control means 43 operates the electric motor 110 based on the information from the sensor 49 and the turning mode selection valve V2 is switch-operated by the electric motor 110 to operate a brake mechanism B to the connection side. Thereby, the traveling device on the turning inside is braked.

Abstract: PROBLEM TO BE SOLVED: To readily confirm the position of an implement, etc., relatively to an object by visual check from a boarding and alighting port of a cabin. SOLUTION: A structure for opening and closing a door of a combine harvester comprises the sliding door 49 slidably composed over a front closing position for closing the boarding and alighting port 40 formed in the transverse lateral part of the cabin 9 covering a boarding driving part 8 and a rear full opening position greatly opening the boarding and alighting port 40. In the structure, the front side of the sliding door 49 is supported with a pair of upper and lower shaking arms 67 and 69 shaking the front side of the sliding door 49 to the front and rear. The rear side of the sliding door 49 is supported with a sliding member 71 sliding along a guide rail 72 directed to the front and rear and composed so that the front end of the sliding door 49 describes a circular arc track K1 and the rear end of the sliding door 49 describes a straight-line track K2 during opening and closing of the sliding door 49. The guide rail 72 is extended from the rear of the cabin 9 to the rear. COPYRIGHT: (C)2006,JPO&NCIPI
