Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lawn mowing machine for continuously cutting grass or weeds and collecting the cut grass. 2. Description of the Related Art Conventionally, as shown in Japanese Patent Application Laid-Open No. 5-56714, a mowing machine which is mounted on a traveling vehicle and continuously cuts turfgrass, and a weeding tank into which the cut turfgrass is inserted are provided. There was a technology to provide. In the prior art, the grass harvesting tank is provided so as to be movable up and down so that the grass inside the tank is discharged from a high place. When working or moving on a road, the grass harvesting tank vibrates up and down due to the shaking of the traveling vehicle, and there is a problem that the tank support is damaged or noise is generated. Therefore, the provision of the stopper for fixing the grass tank at the lowered position eliminates the above-mentioned problem.However, when the grass tank is lowered, it is necessary to operate and fix the stopper each time. At the same time, there is a problem that the operation of releasing the fixing of the stopper is forgotten and the weeding tank is lifted to easily damage the stopper and the like. [0004] A mowing machine mounted on a traveling vehicle to continuously mow turf grass, and a weeding tank into which the cut turf grass is inserted are provided so as to be able to move up and down freely. only set the lifting lever to operate the lifting member for lifting the said only set a stopper for fixing the tank to the lowermost descending position by downward movement of Osamukusa tank lock for releasing operation of the stopper by the rising operation of the lifting lever in a release member set only that mowing machine, is fixed to the lifting lever arm
To the unlocking member, and move the lifting lever to the neutral position.
The operating arm and switch are within the operating range where the
Link the topper and move the lifting lever up from the neutral position
The stopper in the first half of the
Releases the weeding tank fixing operation by the topper.
Just lower the grass tank by operating the lower lever.
The tank is fixed in the lowered position, and the tank
This eliminates the conventional problem of grass tank vibration,
No need for manual operation to fix the hopper
The lifting lever can be easily lifted up
Just remove the stopper and forget to remove the stopper.
The stopper etc. is damaged by raising the link
And the like can be eliminated. Embodiments of the present invention will be described below in detail. FIG. 1 is an overall side view. In the figure, (1) is a four-wheeled traveling vehicle, in which left and right front wheels (2) and left and right rear wheels (3) are connected to a body frame (4).
A steering handle (6) is attached to the rear of the bonnet (5) where the engine and the like are installed, and a driver's seat (7) is provided behind the handle (6). Move forward. In addition, a mower (8) for continuously cutting the foliage of the turfgrass extended to the ground, a harvesting tank (9) into which the cut turfgrass is inserted, and a turfgrass of the mower (8) are collected. The grass tank (9) is provided with a blower (10) and a feeding duct (11) for blowing and conveying. A mowing machine (8) is suspended via a lifting mechanism on the abdomen between the front wheel (2) and the rear wheel (3) of the traveling vehicle (1) so that the driver can lift and lower the driver's seat (7). ing. The front part of the mower (8) is connected to the front support wheel (1).
2), the rear portion is supported by a rear guide wheel (13), and the cutting height is adjusted so that the vehicle runs while following the field scene when lowered. Also, power is transmitted from the front axle case to which the front wheel (2) is attached to the mower (8) via the universal joint shaft (14), and the rotary blade of the mower (8) and the lower (1)
0) is being driven. The lower (10) and the feed duct (11) are arranged on the right side of the seat, and the grass cut by the mower (8) is discharged to the lower (10), and the blades of the lower (10) are rotated by rotation of the blades. The turfgrass is transported to the weeding tank (9) via the feed duct (11). Further, as shown in FIG. 2 to FIG.
A pair of left and right rail bodies (15) (15) and a drum (17) for winding a wire rope (16) are connected to an electric motor (1).

The hook arm (74) is detachably engaged with the hook bolt (75) by the force of the spring (76), and the rear box (63) is combined with the front box (62) fixed to the gantry (20). A hook arm (74) is connected via a rod (78) to an arm (77) integrally fixed to the opening / closing arm (71). An opening / closing lever (8) is provided on the side surface of the rail (15) via a lever stand (79) and a fulcrum shaft (80).
1) is rotatably mounted, an arm (82) integrally fixed to the opening / closing arm (71) and the opening / closing lever (81) are connected by an opening / closing wire (83), and an outer receptacle (84) of the rail body (15). ) And the frame (3)
2) Both ends of the outer wire (86) of the open / close wire (83) are fixed to the outer receiver (85) of the outer wire (8).
The intermediate portion of 6) is extended by being bent to extend freely, and the outer wire (86) is formed to have a length necessary for elevating and lowering the gantry (20). Then, by lifting the open / close lever (81) extending obliquely forward and downward on the side of the driver's seat (7), the open / close wire (83) is pulled to pull each arm (71) around the support shaft (72). ) (77) and (82) are rotated, and the hook arm (74) is rotated via the rod (78) to disengage from the hook bolt (75).
2) After releasing the closing and fixing of (63), the opening / closing arm (7)
By further rotating 1), the opening and closing link (6
8) and the rear box (63) is rotated backward around the pivot shaft (66) via the rotating arm (67) to open the diagonal linear mating surfaces of the front and rear boxes (62) and (63), and The turfgrass inside the tank (9) is discharged downward. An exhaust duct (87) is formed on the rear surface of the rear box (63), and an exhaust port (88) is formed at the lower end thereof. In other words, the front surface of the rear box (63), which is configured in a trapezoidal shape when viewed from the side, is opened to form a mating surface with the front box (62), and the bottom surface (89) is tilted forward so that it can be easily dropped downward. Is formed. Since the front surface of the exhaust duct (87) formed on the rear surface of the rear box (63) is open, it is made of a net, punching metal or the like from the inside of the rear box (63) so as to cover this part. The filter (90) is fixed by bolts and nuts, etc., so that the grass stored in the harvest tank (9) is prevented from being discharged from the exhaust duct (87), and only the transport wind can be exhausted. . As is apparent from the above embodiments, the present invention provides a mowing machine (8) mounted on a traveling vehicle (1) to continuously cut turfgrass, and inputs the cut turfgrass. vertically movably set only the Osamukusa tank (9) for the Osamukusa tank (9) lift lever for operating the lift member (19) for raising and lowering (47)
The setting only, a stopper for fixing the tank (9) to the lowest descending position by downward movement of the Osamukusa tank (19) (5
5) setting only the in the lift lever (47) the unlocking member (60) to set only that mowing machine for releasing operation of the stopper (55) by the rising operation of the lift lever (4
7) An unlocking member for the operation arm (53) to be fixed to
(60) and the lifting lever (47) is in the neutral position.
The operating arm (5
3) and the stopper (55) are linked, and the lifting lever (4
7) In the first half operation of moving from the neutral position to the ascending position
The stopper (55) is further separated from the stopper (55).
To release the fixed action of the weeding tank (9)
The weeding tank 89) is lowered by operating the lever (47).
The tank (9) is fixed in the lowered position just by
The weeding tank (9) moves to the lowered position due to the shaking of the car (1)
Fixed and the weeding tank by the shaking of the traveling vehicle (1)
(9) eliminates the conventional problem of vibration, and
No need for manual operation to fix the stopper (55)
Handling operations can be simplified easily, and
Only by raising the lower lever (47), the stopper (5
5) comes off and forgets to remove the stopper (55).
By raising (9), the stopper (55) etc.
It can eliminate defects such as damage.
