JPH0978624A - Bucket with screening function - Google Patents

Abstract

PROBLEM TO BE SOLVED: To improve the performance of a bucket by providing a screening net for screening concrete wastes, earth and sand, gravel etc., which are. scooped up, in a bucket main body provided with a vibration mechanism at the forward end of an operation arm of a civil engineering machine. SOLUTION: Fixing parts adapted to be connected to the forward end of an operation arm 3 provided in a civil engineering machine 2 are formed at the proximal end of a curved bucket main body 1. A cover is provided between the fixing parts. A motor is attached to the outer surface of the cover. A motor shaft and an eccentric shaft mounted to the motor shaft are covered with the cover. A curved screening net 9 encircled with the body 1 is formed by bridging several bars and drilling a large number of small holes. When the motor rotates, the eccentric shaft rotates so that the net 9 oscillates in inclined state. As a result, concrete wastes, earth and sand, gravels scooped up by the net 9 are screened.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bucket which is attached to the tip of an operating arm of a civil engineering machine and scoops concrete waste materials and gravel at a construction site, a river, a wasteland or an agricultural land.

[0002]

SUMMARY OF THE INVENTION An object of the present invention is to provide a bucket for a civil engineering machine capable of scooping concrete waste materials and the like very efficiently and sieving them directly in the bucket.

[0003]

The means of the present invention are as follows. A bucket equipped with a sieving function that is attached to the tip of the working arm of a civil engineering machine and is mainly equipped with a vibration mechanism, and is equipped with a sieving net for sieving concrete scraps, earth and sand, gravel, etc. .

[0004]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 in the drawings is mainly a curved bucket, and a base 4 is provided with a connecting / fixing portion 4 for connecting to a tip of an operating arm 3 provided in a civil engineering machine 2, and a cover 5 is provided between both fixing portions 4 on the outer surface thereof. Motor 6
And the motor shaft 7 and the eccentric ring 8 attached to the motor shaft 7 are covered with the cover 5. Although not shown in the figure, the motor 6 is provided with a means for rotating the motor 6 by stepping in the operator's cab of the civil engineering machine.

Reference numeral 9 denotes a curved sieving net surrounded by a bucket main body 1, which is constructed by arranging several crosspieces 11 and forming a large number of small holes 12, and is divided into three parts, each of which is a bucket at the tip. A fulcrum member 14 which fits between the left and right sides of the main body 1 and which fits on a pivot 13 is fixed, and at the rear end, a swing connecting piece 1 for two left and right
An eccentric ring 8 mounted on the motor shaft 7 is provided with 5 and 16 pivotally supporting portions 17 and 18, and an eccentric ring arm 19 is fitted and the tip of the arm 19 is mounted on an intermediate fulcrum shaft 20 pivotally supported on the cover 5. 21
Is connected to one end of the oscillating connecting piece 15, and the oscillating connecting piece 16 is connected to the intermediate fulcrum shaft 20 via an intermediate member 17. 22 is a coupling provided in the middle of the intermediate fulcrum shaft 20, and 23 is a bearing.

[0006]

When the motor 6 is rotated by operating the driver's cab, the eccentric wheel 8 rotates, and each curved sieving net 9 is pivoted via the oscillating piece 21, the oscillating connecting piece 15, 16 via the eccentric ring arm 19. The rocking motion is performed with 13 as the fulcrum in a tilted state, and thus, the concrete waste material scooped by the curved sieving net, earth and sand, and gravel are sifted.

[0007]

[Effect] According to the present invention, since the material scooped by the bucket can be sifted in the bucket, compared to the conventional one in which the material once scooped by the bucket is carried to a predetermined place and opened in the sieving machine there. The sifting work can be performed easily and quickly, and the performance of the civil engineering machine as a bucket is greatly improved.
