CS209176B1 - Equipment for quick-clamping or other loader loaders - Google Patents

Abstract

The essence of the invention lies in the fact that a control console is hinged to the boom arm, connected to a hydraulic control lever and provided with a cutout for the bucket's attachment pin, a connecting hole for the locking pin, also passing into the bucket's attachment hole, while the control console is provided with a pick-up tip for contact with the locking plate's slide, connected firmly to the bucket and also provided with a support surface of the control console support.

Description

(54) Equipment for quick bucket or other loading tools to the loader

Annotation

SUMMARY OF THE INVENTION The control arm is articulated to the boom arm, coupled to the hydraulic control lever and provided with a recess for the bucket pin, acting as a connection hole for the locking pin extending into the bucket pin hole, the control bracket being provided with a picking point for contact with the base of the locking plate, fixedly connected to the bucket and provided with a support surface of the control console support.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for fastening buckets or other loading tools to a loader, in particular a front end.

Loaders of front loaders are often mounted on the tip of the crane part of the loader. Various devices are known which allow a relatively quick tool change, in which the jib-operated control bracket of the boom attaches the tool to be attached to its slots by means of a retaining pin. These designs have the considerable disadvantage that the correct connection of the loader and the tool is required for the correct connection, which in practice is only possible with the help of extremely skilled operation or considerable time losses on repeated start-up.

The invention largely removes this fundamental drawback and provides a device for fast, reliable and safe coupling of the front loader tip to the tool, based on a simple principle and serviceable with minimal effort.

SUMMARY OF THE INVENTION In the boom control bracket there is provided a connection hole for a locking pin extending into the bucket grip opening, the control bracket also having a pick-up point for contact with the base plate of the locking plate fixed to the bucket and provided with a support flat support of the control console.

The accompanying drawings show schematically an exemplary embodiment of the device according to the invention, for example on a bucket. Giant. 1 shows a side view of the device in the disconnected state, FIG.

SUBJECT Equipment for quick - release bucket or other ; a loading tool to a loader, in particular a front end, in which a hydraulically operated bracket is articulated to the boom arm, provided with a slot for a bucket pin, characterized in that a connecting hole (16) for the locking pin is provided in the control bracket (5) (11), passing to 3 shows the same device in the connected state and FIG. 3 is a plan view of the connected state. The boom arms 1 are rotatably mounted on a tractor (not shown) or other supporting power source (Fig. 1, 2). Attached to these are pins 13 of the control bracket 5 provided on each side of the bucket 2. Each bracket 5 is formed by a pair of plates 15 (FIG. 3) fixedly connected together. The control bracket 5 has a cutout 14, a connection hole 16 for a locking pin 11 and a second hole 17 for a connecting pin 4 with a hydraulic control lever 3. The control bracket 5 is terminated by a pick-up point 7 and a support 9. the locking plate 6, the inside of which forms the base 8 of the locking plate 6 and the supporting surface 10 of the locking plate 6. The bucket 2 is supported on a support (not shown) and supported face-to-face with a solid obstacle or inserted into a pile of material (not shown). By moving the traction means with the boom arms 1 and thereby iii simultaneously with the control brackets 5, the cut-out 14 approaches the pin 12. The same height of the cut-out 14 is achieved by the operation of the hydraulic control lever 3. 6, until the abutment; 9, the control bracket 5 does not rest against the support surface 10 of the locking plate 6. In this connection, the connection hole 16 is identified with the grip hole 18 and the connection is terminated by the locking bolt 11. and BACKGROUND OF THE INVENTION i the gripping bore (18) of the bucket (2), the control console (5) being provided with a pick tip (7)! for contact with base (8) locking plate (6), fixed to bucket (2) and fitted with | support surface (10) of support (9) of the control console | (5).
