Abstract

PROBLEM TO BE SOLVED: To provide a new sprayer to remove such frequent troubles in conventional work that workers fell from high work places on the slope face, special chemical workers suffered adverse effects on their respiratory organs, eyes, ears and skin by the dust from materials sent by compression air, things dropped on workers from above or unadjusted compressed air blew them off during the spray operations, etc. SOLUTION: The sprayer has such a construction that a nozzle (12) at the end of discharge hose is connected via a universal joint (13) to a top end of a boom (6) installed on a vehicle frame (1), and a chain transmission (15) for vertically swaying the nozzle (13) and another chain transmission (16) for laterally swaying it both via the universal joint (13) are attached to a support arm (60) of a boom end (61 ).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spraying device for greening slopes in high places and a spraying method using the device. That is, a crane work vehicle is used, and the spray nozzle for the greening base material can be swung up and down and left and right, and the outriggers provided on the crane work vehicle can adjust the height of the pedestal to provide an uneven place. But keep the work surface horizontal so that you can work safely.
The purpose of the present invention is to raise the caterpillar from the ground plane so that the caterpillar can change its direction in the levitated state so as not to damage the ground or lawn.

[0002]

2. Description of the Related Art In the conventional spraying method, compressed air from a spraying machine dedicated to spraying mortar is used to spray the sprayed product discharged onto a delivery hose onto the slope from a nozzle at the end of the hose. Is a special worker who performs slope work attaches a lifeline to the rope, fixes the special worker and the hose to the lifeline, and the special worker has a nozzle at the tip of the hose,
The sprayed product discharged was sprayed on the slope to a constant thickness.

Further, in a work vehicle equipped with a caterpillar, there has been an invention of levitating the caterpillar from the ground contact surface to change the direction. For example, Japanese Patent Laid-Open No. 7-
The present invention exists as an invention relating to a combine for harvesting rice of 165028 (former) and an invention relating to a carriage for carrying of Japanese Patent Laid-Open No. 7-251743 (latter). The former has a feature that the direction change is smoothly made in a small turn, and in that case, there is no inconvenience of excavating the soil with the caterpillar.
In addition, the latter has features that it prevents vibration of the transported object mounted on the vehicle body during movement, does not blow up fine foreign matter on the floor surface, and can change the direction of the caterpillar by the piston. ing.

[0004]

However, in the above-mentioned conventional work, a fall accident due to work at a high place on the slope, a respiratory organ relation due to dust of sprayed articles sent by compressed air by a special worker, , There was a bad influence on hygiene such as ears and rough skin. Further, during spraying work, accidents due to falling objects from the top and blowout accidents due to improper adjustment of compressed air were often encountered.

However, in the former case, a rotary support leg that is vertically moved by a hydraulic cylinder is provided in the center of the vehicle body, and since the rotary support leg is single, when the ground contact surface is uneven, Work is dangerous due to lack of stability.

In the latter case, the structure is such that the center part of the vehicle body expands and contracts to levitate the vehicle body. However, in the center part of the vehicle body, the telescopic single support column is extended to levitate the vehicle body. In addition, since it is used for cleaning, it is limited to a place such as a floor or a pavement that is leveled, and it is unstable and unsuitable for use in an uneven place. Both of them can be applied to a relatively small vehicle, but cannot be applied to a super-large crane vehicle that requires an outrigger during work.

[0007]

Therefore, the present invention is provided to solve the problems of the prior art and to achieve the objects of the invention.

That is, according to the first aspect of the present invention, in the spraying device for slope greening, the nozzle at the tip of the discharge hose is connected to the tip portion of the boom installed on the vehicle body frame through the universal joint, and the nozzle is freely movable. A chain transmission mechanism for vertically swinging through a joint and a chain transmission mechanism for horizontally swinging the nozzle are attached to a support arm at the tip of the boom.

The first aspect of the present invention is, in a spraying device for slope greening, a swivel base of a boom, a boom and a driver's seat are installed on a workbench of a body frame, and a caterpillar swivel base is installed under the body frame, The caterpillars are installed on the left and right, and the outrigger mounts are mounted horizontally on the front and back between the body frame and the caterpillar swivel base. A chain transmission mechanism for vertically swinging the nozzle through a universal joint and a chain transmission mechanism for swinging the nozzle left and right are attached to a support arm at the tip of the boom.

[0011]

[Concrete work example] After the crane work vehicle with the boom 6 folded and the work vehicle equipped with the compressor are run to a target location and stopped, the left and right outriggers 10 in front of and behind the body frame 1 of the crane work vehicle. Adjust the height of the pedestal and ground it according to the terrain where the vehicle will stop. Then, the outrigger 10 is further extended to float the caterpillar 7 from the ground surface G until a predetermined space S is reached.

After converting the caterpillar 7 to a desired orientation in this state, the outrigger 10 is reduced and the caterpillar 7 is grounded again. Subsequently, while extending and turning the folded boom 6, the boom is stopped at a position close to the slope A to a distance suitable for spraying work. The nozzle 12 provided at the tip of the boom is operated by remote control so as to move upward U
Then, the nozzle is swung in the downward direction D, the leftward direction L, and the rightward direction R, and the nozzle is set to an appropriate direction and angle for spraying. Then, by driving a known greening base material supply device and a compressor (both not shown), the greening base material is sent to the discharge hose 11, compressed air is supplied to the hose 14, and the tip part is bifurcated from both left and right sides. By sending the material into the nozzle, the material is scattered and sprayed onto the slope A for spraying.

If there is no need to change the direction of the caterpillar 7 at the position where the body frame 1 is stopped, the outrigger 10 can be grounded even if the outrigger 10 is grounded.
There are times when work is done without raising the surface.

[0014]

As described above, according to the present invention, since the nozzle provided at the tip of the discharge hose can be adjusted up and down and left and right, the greening base material is always in an appropriate direction on any slope slope. The spraying work can be done.

Since the present invention has the above-mentioned structure, the caterpillar is levitated by the outrigger when changing the minimum rotation direction for positioning the work vehicle at the work site without damaging the ground or the lawn. Can turn and work.

Further, even when the work site is uneven or uneven, the height of the outrigger can be adjusted to keep the work table horizontal for safe work.
