Description

TECHNICAL FIELD The present invention relates to an improvement of a mobile sorter used for civil engineering, mining, industrial waste, and the like.

2. Related Art and Problems As a first related art, there is known a dedicated debris removing machine equipped with a vibration motor on the outer surface of a side plate formed on a perforated sieve plate (see, for example, Japanese Patent Laid-Open No. 57-38972). As a second conventional technique, there is a dedicated gravel removing machine in which the bottom of the sieve main body having a vibration motor is composed of only vertical stripes (for example, Japanese Utility Model Laid-Open No. 57-140).
(See Japanese Patent No. 888). As a third conventional technique, a bottom portion of a screen body having a vibration motor is provided with a plurality of horizontal rods fixed between both side plates and a plurality of short rods arranged in a zigzag pattern in a length direction in parallel with the width direction of the screen body. It is composed of a vertical rod, and one end of the vertical rod is fixed to the side surface of the higher horizontal rod, and the other end is arranged on the lower horizontal rod so that the horizontal rod and the vertical rod are crossed. There is a dedicated machine for sieving configured as
-4628). Further, as a fourth conventional technique, there is known a debris bucket having a sieve structure in which a bottom portion of a bucket body provided with a vibration motor is constituted by a mesh (for example,

These first to third prior arts are construction site stationary type civil engineering sorting devices each having a structure in which a screen main body is tilted and supported by a support rod, and the screen main body is vertically vibrated by a vibration motor.

Therefore, it must be loaded and unloaded on a self-propelled vehicle each time it is moved, and the device must be adjusted so that the device works well every time this loading and unloading work is troublesome. Therefore, the sorting work time is inevitably shortened, and the sorting work becomes inefficient although the entire working time including the loading and unloading time becomes long.

In the case of the fourth conventional technique, since the vertical and horizontal streaks forming the sieve intersect on one curved surface, even if it is vibrating during operation, soil and sand are likely to adhere, Then, it is hard to peel off and it is easy to cause clogging.

And, all the above-mentioned prior art is a structure in which the sieve body and the sieve net forming the sieve are fixed, and thus the inconvenience that the damaged member cannot be replaced when a part of the sieve is damaged,
There is a problem in terms of service life due to repairing the damaged part.

In addition, all the above-mentioned prior arts have a configuration in which the screen body is vibrated in the vertical direction by a vibration motor for screening, so it may not hinder the use as a sorting device for civil engineering, but for mining and industrial waste. When used for applications such as
There is a concern that the substance to be left as the sieve product may be smashed by being crushed by the sieve mesh and sieved as the sieve product.

In view of the above circumstances, streamlining of sorting work, prevention of clogging,
A drilling blade is installed on the front side of the bucket body attached to the boom of the self-propelled vehicle for the purpose of providing a useful and versatile sorting device as well as enabling replacement of the sieve and / or the sieve screen, proper sieving, etc. And a horizontal reciprocating sieve is provided at the bottom of the bucket body, an excavating blade is provided on the front side of the bucket body attached to the boom of the self-propelled vehicle, and a horizontally movable frame is provided at the bottom of the bucket body. The fact that a sieve mesh that can be attached to and detached from the horizontally movable frame constitutes a powder granule that can be horizontally reciprocated is that the horizontal and vertical lines have a large number of horizontal and vertical lines. While changing the array position to loosely insert,
