Description

Weeder for many purpose road supervision car}

The present invention relates to a mower that professionally weeds around the roads in summer by selectively attaching and detaching it to a multi-purpose road management vehicle for four seasons. And it relates to a multi-purpose road management car weeding device that can safely store the detached mower without damage.

In general, a central divider is installed between the ascending and descending lines of the highway for the safety of drivers and passengers.

Where the central separator is narrow, the central separator made of concrete is installed. If the width of the road is wide or the height of the road is different between up and down lines, landscaping facilities (trees and green areas) are formed in the center. It was to provide the driver to be a comfortable and safe driving.

However, because the grass and weeds grow lushly on the central dividers and shoulders of these highways, and on the shoulders of the national highways, workers had to work on weeding at regular intervals.

Conventionally, such a weeding operation is performed by the worker by hand or by lifting the back of a mowing machine equipped with an engine weighing 20 to 30 kg or the like. Due to the slow speed of the work, a large amount of work cannot be performed, and accordingly, a large amount of work manpower is emerging as an inevitable problem.

In addition, when a mechanical mower is used, the worker's safety accident occurs frequently as the stone is bounced off by the cutting blade rotating at high speed, and the working capacity is limited because the motor capacity is small.

In order to solve these problems, the utility model registration No. 256447 namely a multi-purpose mower for vehicles, which is a mowing machine that is attached to a general vehicle and removes vegetation in various places by using the power source of the vehicle, has been proposed.

However, the pre-registration design has been causing a problem that can not be made smooth weeding operations in the real production, including many problems as follows.

First, unfolding and folding of the boom to unfold the boom in the folded state or to restore the original state by folding the boom unfolding and folding work is very inconvenient, and this delayed the work time.

That is, in order to mow, the moving body fixed to the boom is located in the driver's seat side of the vehicle first, so the moving body must be horizontally moved to the shoulder and then the boom should be extended to perform the work. After having to fold the boom had to be caused accordingly.

In addition, in the movement of the moving body, the sprocket installed in the moving body is rotated to move along the guide member by riding on the linear chain installed on the upper part, but even when the linear chain is installed in a taut state, it is unavoidable that the driving failure occurs during the transfer. As a result, it was not structurally feasible for the sprocket to mesh smoothly with the straight chain.

Second, when weeding works with the moving body placed on the shoulder, heavy loads such as the moving body, boom, cutting device, etc. are biased on one side, so safety accidents such as lifting the other side of the vehicle are heard. Safety was not guaranteed.

Third, due to the nature of the mower used for a limited time in the summer, the situation must be selectively attached to the vehicle according to the season, but in the case of the pre-registration design, there is no detachable device for detaching the mower on an independent basis, so a separate crane must be used when attaching and detaching. The work was very cumbersome, resulting in a lot of manpower and additional crane rental costs.

Fourth, since a separate storage device for storing the mower is not provided in the off-season without using the mower, the mower detached from the vehicle is left as it is on the ground, so the damage of the mower could not be avoided.

The present invention is intended to solve the problems caused by the pre-registered design, to facilitate the folding and unfolding of the boom only by the operation of the first stage boom cylinder boom, and to install the movable outrigger on the passenger seat side where the load is concentrated The main idea of the present invention is to provide a multi-purpose road management weeding device that can ensure safety, detachable mowers without the use of a separate crane, and can be safely stored without damage by removing off-season mowers. It is for the purpose.

The present invention for achieving the intended purpose is a multi-purpose road management car in which the mounting frame is selectively detachable to the fixed frame mounted on the front bumper of the truck and various special equipment is installed on the mounting frame, the front side of the mounting frame A horizontal rotating frame rotatably installed horizontally; A first stage boom having a pivot formed at right angles on one side so as to be rotatable up and down on the horizontal pivot frame and having support wheels formed at the bottom of the other side; A first stage boom cylinder installed between the first stage boom of the pivot base and the other side of the pivot part of the horizontal pivot frame; A two-stage boom rotatably installed at the front end of the first-stage boom and connected to the first-stage boom and a telescopic cylinder and provided with a mower capable of adjusting a rotation angle at the other end; A movable outrigger installed on the horizontal rotating frame so that height can be adjusted, and a movable wheel freely moving on all sides thereof; It is made by providing a herbicide storage means consisting of a storage stand that is selectively detachable to the other end of the rotating frame of the rotating frame and a support detachable to the lower side of the movable outrigger.

It can be folded or unfolded.

Meanwhile, the second stage boom 40 rotatably installed at the front end of the first stage boom 20 by the rotation shaft 42 is rotatably installed at the other end. Here, the expansion and contraction control of the second stage boom 40 is possible by the operation of the expansion cylinder 43 installed between the first stage boom 20 and the cylinder bracket 41 installed on the second stage boom 40, and the rotation of the mower 6. The weeder (6) according to the road slope of the weedy area by the operation of the rotary angle cylinder (45) installed between the rotary link 44 and the second stage boom 40 installed on the mower (6) and the second stage boom (40). The angle of can be adjusted arbitrarily.

The movable outrigger 50 installed perpendicularly to the horizontal rotating frame 10 supports the passenger seat side to the ground stably during the weeding operation so that heavy loads of the mower 6, the first stage boom 20, and the second stage boom 40 are applied. It prevents safety accidents caused by the side of the passenger seat, and moves the mounting frame 4 to the upper part when detaching and attaching the mower 6 by self-propelled. 6) is to keep a stable from the ground.

In the multifunctional movable outrigger 50 which plays such an important role, the fixed outer shell 51 of the rectangular body is vertically penetrated to the horizontal rotating frame 10 as shown in FIG. A conveyance inner tube 52 is installed to be slidably transported up and down, and a height adjusting cylinder 53 is provided inside the conveyance inner tube 52 to selectively adjust the height by applying a conveying force to the conveying inner tube 52. .

The height adjustment cylinder 53 is fixed up and down by fixing pins 55 penetrating the fixing cap 54 fitted to the upper side of the fixed outer shell 51 and the lower both sides of the transfer inner tube 52, the upper and lower It is possible to adjust the height by slidingly conveying the conveying inner tube 52 selectively through the stretching operation.

Although not shown in the drawing, the bottom surface of the conveyance inner tube 52 is provided with a rotary support 56 in which bearings are embedded, and a movable wheel 57 is installed freely in all directions at the lower end of the rotary support 56. .

Meanwhile, the mower storage means 60 for stably separating and removing the weeding device used in the summer from the fixed frame in a stable manner is a storage stand 61 which is selectively detachable to the fixed plate 14 of the horizontal rotating frame 10, and a movable outer. It is composed of an L-shaped support 65 detachable to the lower side of the trigger 50.

First of all, referring to the configuration of the storage stand 61 that stably supports one side of the weeding device, a square holder 61-1 is attached to the fixed plate 14 of the horizontal rotating frame 10 as shown in FIG. 11, and the square holder ( 61-1) is fitted with a strut 61-2 placed on an upper end of the storage stand 61. At this time, the post 61-2 is provided with a stopper pin 61-3 horizontally before and after the predetermined height, and the stopper pin 61-3 supports the bottom surface of the square holder 61-1. The square holder 61-1 and the support 61-2 are coupled to each other through the fixture 61-4 so that no flow is generated, and a pair of support wheels 61-5 are installed at the bottom of the storage stand 61.

Next, the configuration of the L-shaped support 65 for stably supporting the other side of the weeding device has an insertion hole 65-1 is formed in the movable wheel 57 of the mobile outrigger 50 and the insertion hole 65-1 The insertion hole (65-1) and the insertion portion (65-2) is fixed pin (65-3) while the insertion portion (65-2) is formed to be bent upward on one side of the L-shaped support (65) The fitting protrusion 65-4 installed at the upper end of the insertion part 65-2 is inserted into the rotation preventing groove 65-5 of the rotation support 56 so that the L-shaped support 65 rotates. There will be no. The support wheel 65-6 is installed on the other side of the insertion part 65-2, so that the weeding device is stably supported on the road along with the support wheel 61-5 of the movable wheel 57 and the storage stand 61. Thus, it is possible to prevent the weeding device from being damaged in advance.

It will be described the operating state of the subject innovation made in this configuration.

First, look at the unfolding process of the boom when preparing the weeding operation in the state of folding the boom compactly in front of the truck (2) as shown in Figure 1 by operating the expansion cylinder 43 as shown in Figure 2 the two-stage boom (40) When the first stage boom cylinder 30 is contracted in the unfolded state, the pivot table 21 and the first stage boom 20 are rotated in the counterclockwise direction about the rotation shaft 22.

At this time, when the first stage boom 20 rotates to reach the dead point (the angle of the rotation table 21 and the first stage boom cylinder 30 is 180 degrees), the first stage boom cylinder 30 is no longer able to contract. In the state, when the first stage boom 20 is out of the dead point using ∑ M1> ∑ M2, the first stage boom cylinder 30 is expanded to rotate more smoothly in the opposite direction of rotation, while the first stage boom 20 is toward the shoulder as shown in FIG. 3. As it unfolds, the work area can be doubled.

Therefore, the boom can be quickly and simply unfolded only by the expansion and contraction of the first stage boom cylinder 30, and the boom can be folded compactly in its original state through the reverse order of the unfolding process, thereby providing convenience in operation.

As described above, when the movable outrigger 50 is lowered in the state where the boom is unfolded, the movable wheel 57 is grounded to the ground, thereby stably supporting the load on the passenger seat to perform a smooth weeding operation at the same time.

Next, look at the process of detachable detachment of the weeding device of the present invention if the inflated first stage boom cylinder (30) in a state in which the movable wheel 57 of the mobile outrigger 50 is grounded to the ground as shown in FIG. The pivot wheel 21 and the first stage boom 20 are rotated clockwise about the pivot shaft 22, and the support wheel 23 is grounded to the ground.

As described above, when the movable wheel 57 and the support wheel 23 are simultaneously grounded on the ground, the height-adjusting cylinder 53 and the first-stage boom cylinder 30 are continuously inflated to the mounting frame 4 and the horizontal rotating frame ( While the connecting frame 4a of the mounting frame 4 connected to the fixing member mounted on the truck 2 is automatically conveyed to the upper portion, the mounting frame 4 is separated from the fixing frame while the upper portion is transferred to the upper portion. When the truck 2 is reversed in the state, the weeding device can be completely detached from the truck, and the attachment method of the weeding device is enabled through the reverse of the desorption process.

Therefore, the weeding device of the present invention can be detachably detached by the driver alone without a separate crane work, thereby reducing the cost of additional manpower and equipment rental.

As described above, the detached weeding device is installed by inserting the holder 61 into the square holder 61-1 on one side as shown in FIGS. 9 to 10, and inserting the L 61 into the insertion hole 65-1 of the other movable outrigger 50. After installing the type support (65), the height adjustment cylinder (53) and the first stage boom cylinder (30) by shrinking the support wheels (61-5) of the movable wheel (57) and the storage (61), L type support (65) By supporting wheel (65-6) of the ground to the ground it is possible to stably store the weeding device.

This design provides the convenience of operation by simply unfolding or compactly folding the boom simply by the expansion and contraction of the first stage boom cylinder, providing the convenience of operation, and stably supporting the load on the passenger seat while the mobile outrigger is grounded to the ground. It is possible to carry out smooth weeding at the same time as driving, and it is possible to drastically reduce the cost of additional manpower and equipment rental by attaching and detaching the weeding device independently by the driver without separate crane work.

In addition, by using the mower storage means is provided an effect that can be safely stored without damage to the off-season mower.
