Abstract

(57) [Summary] (Correction) [Purpose] A mechanism for mounting a reciprocating mower in front of a self-propelled aircraft and controlling its inclination angle. [Structure] One instruction lever is provided near the side of the traveling handle, which is capable of adjusting the inclination of the side mower projecting to the one side in front of the self-propelled aircraft horizontally downward and vertically adjusting the side mower. . Therefore, the general versatility such as continuous response to slopes or cutting of branches such as shrubs protruding to the road side was improved while running cutting.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a configuration in which a reciprocating mower is provided in front of a self-propelled aircraft.

[0002]

[Prior art]

 A technique of inclining a mower in front of a self-propelled aircraft is known as Jikho Sho 63-17311. This known tilt control mechanism is provided with a manual handle for locking and fixing the mower mounting base at an arbitrary rotational position.

[0003]

[Problems to be solved by the device]

 The conventional device described above is inefficient because the engine is stopped and the handle is rotated each time the inclination of the mower portion is desired to be adjusted.

[0004]

[Means for Solving the Invention]

 In order to solve the above-mentioned problems, in a self-propelled mower that has a traveling handle, a machine frame, an engine, and a reciprocating mower on the front, the reciprocating mower that projects at least on one side is inclined downward from horizontal. The present invention provides a self-propelled mower characterized in that a single instruction lever that can be adjusted and set up vertically is provided close to the traveling handle.

[Action]

 Start the mowing work on the side of the road by holding the traveling handle, and push the indicator lever forward if the slope is sloped downward on one side. Further, when a branch of a shrub or the like is approaching the road side, it is advisable to pull the indicator lever toward you and set it upright as shown in FIG.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A configuration will be described based on the drawings in which the present invention is implemented. FIG. 1 is a right side view of the present invention. An engine 1 is mounted in the center of the machine casing 3, and a center mower 4 and side mowers 5 are provided in the front. Reference numeral 7 is a traveling handle and 8 is a traveling wheel. In this embodiment, it is of a crawler type and is driven by the engine 1 through an appropriate transmission mechanism.

Reference numeral 2 denotes a transmission case, which is input from the engine 1 through the output shaft 9, and swings the receiving member 11 from the swinging portion A10 to drive the reciprocating portion. A base of a support bracket 13 that supports the side mower 5 is pivotally attached to a rotary shaft 12 provided on the machine frame 3 side. Reference numeral 16 is a rod which is connected to the crank 15 to regulate the inclination angle of the side mower 5.

A swinging portion B is output from the transmission case 2 to drive the center mower 4.

FIG. 2 is a left side view, particularly for explaining a configuration for adjusting the inclination of the side mower 5. The instruction lever 6 swings back and forth around the support shaft 22 as a fulcrum. A push button 17 is provided on the head of the instruction lever 6, and when pushed, the stopper pin 18 descends and disengages from the engaging groove 19 to become free. When pushed forward (F1) and the weight of the side mower 5 causes it to descend via the connecting rod 14, crank 15 and rod 16 to conform to the slope, and at that time, when the push button 17 is released, the stopper pin 18 is engaged. It is fixed by engaging with the groove 19. Page (3)

FIG. 3 is a plan view showing the transmission of the front mower 4 and the side mower 5 which are particularly mounted. It is transmitted from the engine 1 to the transmission case 2 via the output shaft 9. The transmission case 2 drives the mower by the swinging part B20. On the other hand, the swinging portion A10 reciprocally slides on a sliding piece 21 slidably provided on the rotating shaft 12. The sliding piece 21 swings the receiving member 11 around the base shaft 23 as a fulcrum to cut the side mower 5.

The base of the support bracket 13 that supports the sliding piece 21 and the side mower 5 is an inclined fulcrum that also serves as the rotation shaft 12.

FIG. 4 is a work state diagram of the side mower, showing the front. When the front mower 4 is installed on the front of the machine frame and the side mower 5 is installed on one side, when it is lowered from the horizontal state to the slope, it stands vertically to cut the protruding branch of the shrub. Is shown.

Further, it is convenient to turn off the power of the mower portion and to stand the side mower 5 upright when moving on the road without any hindrance. It should be noted that as the mower angle adjusting means, the lifting and lowering by a hydraulic cylinder and the lifting and lowering of an electric cylinder are the same.

【effect】

 With the above-mentioned structure, it is convenient that the traveling angle of the side mower projecting to one side of the self-propelled mower can be adjusted arbitrarily with a single instruction lever.
