Description

[Detailed description of the invention] This invention relates to a loader that scoops up deposits such as waste and continuously discards them backwards.

Traditionally, a loader has been used to scoop up and load deposits such as waste, but the work methods include scooping with a bucket, lifting the bucket,
The method used is to rotate the vehicle 180 degrees while backing up, overturn the bucket, and abandon it, which requires a lot of operation and time, and is not only inefficient, but also has the disadvantage of being troublesome and tiring for the driver. It was hot. Particularly when working in narrow spaces such as tunnels, it is impossible to turn the vehicle body 180 degrees, and for this purpose some models have been implemented that allow the upper part of the vehicle to rotate freely, but the side walls become an obstacle. In some cases, it was not possible to perform a sufficient turning operation, and since turning required a certain amount of time, work efficiency was reduced accordingly. The purpose of this invention is to provide a loader with good working efficiency that does not have these drawbacks.

For this purpose, a boom that can be raised and lowered by a hydraulic cylinder on a frame protruding from the upper revolving body and that allows rock blocks to roll inside, a bucket that is attached to the tip of the boom and has a hole in the bottom for the rock blocks to pass through, a frame, and a hole through which a lump can pass through the inside of the rotating body;
It consists of a belt conveyor etc. installed inside the lower running body.

If you scoop it up with a bucket and push it upwards, the lumps will fall out from the bottom of the bucket, and the boom, frame,
It reaches the top of the belt conveyor through a swivel platform and is discharged to the rear.The work is simple, such as scooping it up with a bucket and moving the boom up and down, so the work efficiency is very high and the operator is less fatigued.

Examples will be described in detail below with reference to the drawings.

Reference numeral 1 denotes a lower traveling body, and 2 denotes an upper revolving body. A belt conveyor 3 is installed inside the lower traveling body 1 in the front-rear direction. The belt conveyor 3 is connected to the upper revolving body 2
The purpose is to carry and dispose of falling stones rearward, and the rear part is bent upward to make it easier to load into the transport vehicle 4. A frame 5 of the upper rotating body 2 can be rotated left and right by a hydraulic actuator (not shown). A hole 6 for passage of agglomerates is formed inside the frame 5 and the upper revolving body 2, and a chute cover 7 is attached to the rear of the frame 5 to prevent the agglomerates from scattering. 8
is a boom, the front end of which is connected to a bucket 9 so that it can be rotated up and down with a hydraulic cylinder 10, the rear end is connected to the upper end of the frame 5 so that it can be turned up and down with a hydraulic cylinder 11, and the inside is The cross section is shaped like a mold to prevent the stones from falling to the side, the bottom surface is formed as a smooth surface so that the stones can roll, and the rear end is open so that the stones can fall backwards. The bottom rear part of the bucket bag 9 is cut out over a considerable width to form a hole 12, so that when the bucket bag 9 is directed upward, the lumps of stone fall out from the hole part 12. Note that 13 is a seat and 14 is an operating lever.

Although the present invention is constructed as described above, the actual operation will be explained below.

The hydraulic cylinder 11 is operated to lower the boom 8 to the excavation position, the hydraulic cylinder 10 is operated to direct the bucket 9 forward, and the vehicle body is moved forward to excavate. Next, when the hydraulic cylinder 11 is actuated to lift the boom 8, the bucket 9 rotates naturally, and the excavated soil is poured into the boom 8 from the hole 12 at the rear lower part of the bucket 9.
It fell down and slid down the inside of the slanted boom 8,
The boom 8 falls directly from the rear end of the boom 8 or hits the chute cover 7 and passes through the hole 6 of the frame 5 and the hole of the upper revolving structure 2 onto the belt conveyor 3, and is carried backward by the belt conveyor 3 and transported to the transport vehicle 4. be disposed of above.

As mentioned above, the present invention has a hole in the rear lower part of the bucket and allows the earth and sand to slide inside the boom, so if the bucket is lifted upwards after excavation, the excavated earth and sand will flow from the bucket into the boom. In addition to falling and sliding within the boom, the frame
A hole is provided in the upper revolving body, and a belt conveyor is provided below the hole so that the earth and sand that falls from the boom passes through the hole, falls onto the belt conveyor, is carried backwards, and is disposed of. Unlike conventional loaders, there is no need to change the direction of the vehicle to dump the load to the rear; simply lift the bucket and the dirt will naturally fall out and be carried to the rear via the boom and belt conveyor. In this way, the work is simple and efficient, and can be performed even in confined spaces. In addition, since it is easy to operate, the driver is less fatigued, can work for long periods of time, and has good work efficiency.
