JPH05209419A - Multipurpose front bucket for hydraulic variable direction type loading shovel - Google Patents

Abstract

PURPOSE: To change the angle of inclination at oil pressure within a certain restricted range even in either direction of one direction or another direction by simple mounting and demounting works capable of being easily conducted at a site in a narrow space. CONSTITUTION: A bucket can be rotated pivotally not only on a pivot 1 but also on a pivot 2. On the other hand, the position of a jack 3 ensuring the direction of the bucket can be changed from a support 4 to a support 5 and from a pivot 6 to a pivot 7. Accordingly, the bucket can be directed in either direction of one direction or another direction to the vertical shaft of a conveying bucket machine.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading shovel bucket, and more particularly to a loading shovel bucket whose tilt angle can be hydraulically changed in any of left and right directions within a certain limit range. is there.

[0002]

2. Description of the Related Art Currently, a loading excavator bucket mounted in front of a transporting machine, which is generally composed of a system having three fixed or pivot axes, is used. It is known that it is possible to change by turning four wheels which are symmetrical with respect to the machine longitudinal axis.

Such systems are also very complex in terms of machine structural design and, moreover, the width of the machine occupies a large space on the work course, and the small space often makes it impossible to carry out this type of work. .

In other types of machines that are actually used, a special device can be used to work with thin plates that can be tilted and tilted, but this can only be used for embedding or snow removal, and for buckets. Material such as shovels cannot be loaded.

SUMMARY OF THE INVENTION The present invention provides a hydraulic pressure within a limited range in one direction or the other due to a simple mounting and dismounting work which can be easily performed on site even in a narrow space. An object of the present invention is to provide a multipurpose front bucket for a loading excavator whose tilt angle can be changed.

[0006]

On the contrary, if the present invention is adopted, the occupation space of the width of the machine does not actually change, and the inclination of the loading bucket with respect to the traveling direction of the machine operates a simple adjustment jack. This can be easily changed within a certain limit range.

Reversing the inclination direction of the loading bucket can be easily performed by simple attachment and detachment work of the mechanical member, and this work can be easily performed at the work site of the machine using a small number of tools. it can.

The present invention will now be described in more detail with reference to the accompanying drawings.

As can be seen in FIG. 1, the buckets are mounted with two pivots 1 by inserting these pivots inside a bush provided in a chassis for supporting said buckets, and thus on the frame. The bucket is tilted to some extent with respect to the machine's axis of travel by actuating a hydraulic jack 3 which connects a support 4 provided on the to a pivot 6 mounted on a bracket integral with the bucket frame. It is possible (see FIG. 2).

As can be seen from FIG. 3, the orientation of the bucket is symmetrical with the position of the support 4 with respect to the longitudinal axis of the machine on the transport chassis by using two pivots 2 provided on the opposite side of the pivot 1. Mounting the jack 3 on the support 5 which is mounted on the opposite side of the jack and finally connecting the movable rod of the jack 3 to the pivot 7 on the opposite side of the pivot 6 on the chassis of the bucket symmetrically , It is possible to reverse.

In any case, it is easily understood that by operating the jack 3, it is possible to accurately adjust the inclination angle of the bucket with respect to the traveling axis of the machine.

Other mechanical features relating to the raising and lowering of the bucket and the opening and closing movements of the opening and closing bottom of the bucket are unchanged compared to known types of machines.

Although structural details of the device are described and illustrated herein with respect to particular structural embodiments, these are merely examples and are not limiting, as these details are claimed. It is also clear that it is possible to take different shapes and embodiments while maintaining the basic characteristics of the invention without departing.

Claims (2)

[Claims] 1. In a multipurpose front bucket for a hydraulic, variable-direction load excavator, comprising a carrying chassis which can be raised and lowered by means of control means attached to a machine of a type known per se: the chassis supporting the bucket is of the frame To connect the support (4) connected to the frame with two pivots mounted on one side and integral with the carrying chassis to the pivot (6) provided on the support integral with the bucket body A jack (3) is provided,
As a result, the bucket is capable of variably projecting forward within a limited range along one direction with respect to the traveling axis of the machine, and is a hydraulic type variable-direction multipurpose front bucket for a load shovel. 2. A bucket is mounted at a position opposite the bucket body by means of two pivots (2) fixed to the transport chassis and an adjusting jack (3) is provided symmetrically with respect to the support (4). By mounting it between the support (5) and the pivot (7) which is itself symmetrical to the pivot (6) mounted on the bucket body, the bucket is oriented in the opposite direction to the machine's axis of travel. The multipurpose front bucket for a hydraulic excavable load shovel according to claim 1, wherein the occupied space of the width of the machine is not changed in any case.
