Description

[Detailed explanation of the invention] This invention relates to an on-vehicle dust remover for scraping up and removing driftwood and garbage hanging on dust removal screens installed in intake channels of dam reservoirs, lakes, and settling ponds. be.

Conventionally, in order to remove dirt, sand, etc. from dust removal screens installed in waterways such as dams or sewers, the screen is pivoted to a support structure so that the tilt angle can be changed around a horizontal axis parallel to the screen. A dust removal device is known in which a vertically extendable tubular arm is attached to a guide holder, and a rake is attached to the tip of the arm so that it can be lifted up and down by a hydraulic cylinder.

By the way, in conventional such devices, the rake arm is attached to a fixed support structure, so it can only be used for one screen, the operating rate is low, it is extremely uneconomical, and a considerable amount of waste is wasted in construction. there were.

A traveling trolley-type dust remover is also known, which allows the dust remover to run on rails laid parallel to waterways, but it has a considerable operating rate in areas where dust removal screens are lined up, but There was a problem in that the collected driftwood and garbage had to be moved to a predetermined location by a conveyor and then transported by truck to an incinerator or the like again.

This invention aims to provide an on-vehicle dust remover that can eliminate the above-mentioned problems.The feature is that the dust remover can be loaded onto a vehicle, such as a truck, and moved to any location. The garbage and driftwood that have been raked and pulled up can be collected on trucks and transported to a designated disposal site for disposal, thereby increasing the efficiency and operating rate of the dust removal work. It is in.

Hereinafter, embodiments of this invention shown in the drawings will be described.

In the drawings, 1 is a vehicle such as a dump truck, and a predetermined space 4 is provided between a driver's cab 2 and a loading platform 3.
A swivel base 5 is fixed on this space 4.

A post 6 is erected on the swivel base 5, and a jib 7 is pivotally mounted to the upper end of the post 6 by a hydraulic cylinder (not shown) so as to be able to move up and down.

At the tip of the jib 7, the upper end of a movable arm 8 which is freely extendable and retractable is pivotally attached to the upper end of the movable arm 8 by a horizontal pin 9 so as to be able to move up and down, and the jib 7 is made to move up and down by a hydraulic cylinder 10 provided between the two.

A dual hydraulic cylinder 1 is installed at the upper and lower ends of the movable arm 8.
Both upper and lower piston rods 12 and 13 ends of the piston rod 1 are attached to the cylinder 11 so that they can be expanded and contracted.

Reference numeral 14 denotes a rake assembly, which is composed of a rake arm 15, a rake main body 16, a rake opening/closing hydraulic cylinder 17, and a support guide member 20 having guide rollers 18 and 19 at the top and bottom. It is detachably attached to the lower end 8A of the movable arm 8.

The rake body 16 is configured in a packet shape by a rake frame 16A and punching metals 16B and 16C fixed on all sides so as to open downstream and upward, and the upper end of the rake frame 16A is connected to the lower end of the rake arm 15 by a horizontal pin 21. It is pivoted by ξ.

The lower end of a piston rod 22 of a hydraulic cylinder 17 is pivotally attached 28 to the central upstream side of the rake frame 16, and the end of the hydraulic cylinder 17 is swingably attached to the upper upstream side of the rake arm 15 by a horizontal pin 23. ing.

Further, on the downstream side of the lower end of the rake arm 15, the support guide member 20, which has an inverted dogleg shape when viewed from the side, is fixed and protrudes toward the downstream side.

The lower half of this support guide member 20 is parallel to the rake arm 15, and the guide rollers 18 and 19 whose outer periphery is fitted with an elastic member such as rubber are pivotally attached to this lower half. Rake assembly 1 by rollers 18.19
This is to absorb the shock when the bar screen 24 comes into contact with the bar screen 24.

Further, 25 is an intake channel, 26 is a slab constructed above and across the intake channel 25, and 27 is a channel bed.

Note that the punching metal 16B of the rake body 16,
16C may instead be assembled using bars and tie bolts as in the past, and the punching metal levers 16C on both sides may be omitted.

Next, the dust removal work performed by the dust removal machine according to this invention will be explained.

First, as shown by the two-dot chain line in FIG.
4 is positioned on the loading platform 3 by retracting and rotating the movable arm 8 141, and the truck 1 is driven to lie parallel to the screen 24 of an arbitrary waterway or the like.

Therefore, with the rake open, the post 6 is turned 90 degrees to bring the rake assembly 14 to the position shown by the two-dot chain line 142 in FIG. After the guide rollers 18 and 19 of the support guide member 20 are brought into contact with the movable arm 8,
The rake main body 16 is opened and the supporting guide member 20 is used to collect the driftwood and debris while pushing it into the water, and when it approaches the channel bed 27, the rake main body 16 is closed by the rake opening/closing hydraulic cylinder 17 and the second rake main body 16 is collected. The state is shown by the solid line in the figure.

Driftwood and garbage have been collected by the rake assembly 14 in the previous operations, and the rake assembly 14 is guided by the bar screen 24 as indicated by the two-dot chain line in FIG. The state 144 is reached through the state 143 shown in FIG.

Next, rotate the post 6 by 90 degrees and install the rake assembly 1.
4 onto the loading platform 3, and the rake opening/closing hydraulic cylinder 17
is operated to open the rake body 16 to the state shown at 141 in FIG.

In this way, one cycle of driftwood/garbage removal work is completed, this work is repeated, and when the truck bed 3 is full of trash, the truck 1 is driven to a waste collection site or incinerated All you have to do is transport it to the field and drop it.

As mentioned above, this device is installed on the vehicle, so as long as there is a passageway, it can be moved to the screen position of any waterway etc. and the dust removal work can be carried out. Not only can driftwood and garbage be stored on the loading platform and transported to an incinerator and then dumped, but unlike conventional methods, separate dust removal machines can be installed on the screens of each waterway. It is possible to significantly reduce equipment costs as there is no need to install a Since it can be easily carried out in any location, and it can be stored away from the rain, its lifespan can be greatly extended, and there are great expectations for its effectiveness as it will make a significant contribution to reducing labor costs and other miscellaneous expenses.

In addition, in the embodiment of this invention, a dump truck equipped with a dust removal machine has been described, but it is also possible to install a dust removal machine on a vehicle without a loading platform 3, and have the garbage received and transported by a separate tap truck or the like. Accordingly, the operating rate of the dust removal machine can be further increased.

Furthermore, a rake assembly 1 is attached to the lower end of the movable arm 8.
4 can be replaced with a packet of another type to remove dirt, sludge, etc.
