Abstract

A demountable skip emptier is in the form of a mild steel container that can be carried on the back of a lorry, and has means for lifting and tipping a skip 6, at one end of the container, together with means for forcing rubbish from the skip into the container. <IMAGE>

Description

THE DEMOUNTABLE SKIP ET-.PTIER.

TLCHNI^AL FIELD This information relates to a means of emptying industrial/ domestic waste skips.

BA~KGROJND The waste skip is a well-known means of disposing of waste, both industrial and domestic. The problem is that when sKips are trans; orted on the wagon they may have relatively little weight in proportion to the capacity of the skip. This means that the vehicle is travelling frm site to tip under its potential weight capacity and therefore under-utilised.

The skip emptier is a means whereby numerous skiis have their contents emptied and crushed on the site of each individual skip thereby eliminating the need for unnecessary journeys to the tipping site.

ESSENTIAL TECHNICAL FEATURES According to the present invention there is provided a demountable mild steel container which is transported by skip wagon/multilift/Rolonof/fixed chassis cab, to the required site.

The vehicle backs up to the skip and by means of hook, trunnions and hydraulic lift, the skip is lifted up into the air and a hydraulic door empties the skip and crushes the rubbish into an enclosed container.

A specific embodiment of the invention will no be described by way of example with reference to the accompanying drawing in which: Figure 1. shows in perspective the skip emptier in position on the skip wagon. The skip emptier is lifted onto the skip wagon in the conventional manner and by means of connecting two hydraulic self seal couplings the skip emptier is ready for use.

Figures 2-5. assume the ski emptier is mounted on the vehicle.

Figure 2. The skip is originally modified by welding two trunnions 8 onto the front of the skip and by use of the existing lugs 9 on the back of the skip. The illustration shows the skip erptier backed up to the skip 6 and by means of the hydraulic control valves 5 the skip lifting arms 3 are lowered by means of the hydraulic cylinder 4 the chains 10 are attached to the existing lugs 9 on the skip.

Figure 3. By operation of the control valves 5 the lifting arms 3 lift the skip into the air catching on the hooks 11 on the back of the skip emptier.

The hydraulic doors 1 are opened using hydraulic cylinder 2.

Figure 4. The hydraulic doors extend into the skip by means of the hydraulic cylinder 12 and by the operation of hydraulic cylinders 2 the rubbish is forced out of the skip into the skip emptier.

Any spillage is controlled by a litter screen 7.

Figure 5. shows the completed cycle with all the rubbish in the skip emptier. By operation of the skip lift 3 the skip is lowered to the ground and disconnected from the skip emptier.

Figures 6 & show the construction of the hydraulic door which is controlled by the hydraulic cylinder 12 built into the hollow sections controlled by hydraulic control valve 5.

On the edge of the hydraulic door there are rubber strips 14. The rubber strips allow for variation of skip widths and also fcrm a litter tight seal when the hydraulic door is closed.

Figure 8. The skip emptier has a moveable ejector Relate 15 mounted on rollers 16 which move from the front of the skip etnptier to the rear forcing out the rubbish on to the tip.

Figure 9. The moveable ejector plate 15 is connected to the hydraulic doorlby means of a chain 17 which therefore alleviates the need to have an hydraulic cylinder to operate the ejector plate 15. The ejector plate 15 is forced back to the front of the skip emptier by the rubbish as the skip emptier is being filled.

Claims

CLAIMS.

1.

A Demountable Skip Emptier comprises of a mid steel container that can be lifted onto a skip loader / multi lift ; rolonoff.

It works by means of a hydraulic packer mechanism actually going into the skip and forcing rubbish into the container.

2.

A Demountable Skip Emptier as claimed in 1. wherein hooks are provided on the skip emptier to co-operate with the skip to control the locking and lifting of the skip.

3.

A Demountable Skip Emptier by virtue of it design uses the skip as a hopper and thereby the full capacity of the skip emptier is used for waste.

4.

A Demountable Skip Emptier by virtue of the hydraulic packer mechanism as claimed in 1. goes into the skip. This system can be used on conventional skips by welding on two trunnions thereby alleviating the need for expendi-ure on net specialized ski ps

5.

A Demountable Skip Emptier maizes a skip loader a dual purpose vehicle i.e. emptying either conventional heavy builders waste sips or light industrial skips.

6.

A Demountable Skip Emptier by using the skiL as a hopper alleviates the weight problem created by conventional rear end loaders.

7.

R Detrountable Skip Emptier by virtue of its design in not having a fixed hopper allows the rubbish to enter the skip emptier more quickly and efficiently with less mechanical damage to the hydraulic system, doors and skip compared to a conventional rear end loader.

8.

A Demountable Skip Emptier by virtue of its construction by connecting the hydraulic packer to the ejector plate allows the rubbish to be forced to the rear end of the skip emptier and thereby onto the tip. This alleviates the need to use another hydraulic cylinder and therefore reduces both the cost and weight of another cylinder.
