Abstract

PURPOSE:To enable a reclaimer to scrape and clean out remnants left behind by itself by providing a vertically movable scraping plate at the tip of a link installed elastically on the tip of a boom. CONSTITUTION:The upper part 13 of the boss of a link 12 is rotatably connected to a bracket 14 at the upper head part of a boom 2, while the lower part 15 of said boss is slidably connected to a guide hole of a bracket 16. Further, a guide frame 17 is provided with a cylinder 20 and a scraping plate 21. In case there are remnants 4 left behind, the link 12 is extended by means of a rod 24 of a cylinder 22, further the cylinder 20 is extended to lower a plate 21 and either oppose it to or make it cut into said remnants 4. Later, the rod 24 is contracted and the remnants are scraped up to the position of a bucket wheel 3.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is capable of continuously collecting loose materials such as coal, iron ore, limestone, and sand using packet foils, and scraping the materials left behind during the reclaimer's discharging work by the reclaimer itself. This relates to a device that collects and dispenses packets using packet foil.

When determining the working radius of the reclaimer at the storage site, economic efficiency must be fully considered.

Conventionally, as shown in FIG. 1, a reclaimer having a packet foil 3 on a boom 2 must minimize the radius in which bulk materials 1 can be handled over the entire area of the storage area to minimize an increase in the cost of the reclaimer equipment. For this reason, the work radius is determined by recognizing a certain amount of leftover amount, and auxiliary machines such as bulldozers are used in conjunction with the treatment of the leftover portion 4. However, these auxiliary machinery incur costs such as fuel costs, labor costs, and maintenance costs that are not related to the reclaimer itself.

In the discharging work of the beam reclaimer of the present invention, the working radius of the reclaimer is not set to a radius that allows work to cover the entire area of the accumulation site as in the past, and the remaining amount is recognized. The purpose is to collect and dispose of leftovers by the reclaimer himself.

The main point of the present invention is that a reclaimer that scoops up handled items with a packet foil provided on a boom has a basic configuration in which a telescopic link is provided at the tip of the boom, and a scraping plate is provided at the tip of the link so as to be movable up and down. , the scraping board is lowered to hit the leftovers at a position where the packet foil cannot reach, and the link expands and contracts to scrape up the leftovers to a position where the packet foil can reach.

An embodiment of the present invention will be described below based on FIG. 2.

As shown in FIG. 2, a packet foil 3 is rotatably provided in the pool 2 of the reclaimer. Therefore, when the packet foil 3 is rotated, the packet 6 of the packet foil 3
In the section, the object 1 to be handled is scooped up onto a conveyor on the pool 2, and the object 1 to be handled is discharged through this conveyor.

The upper base 13 of the pantograph link 12 is rotatably connected to the bracket 14 at the upper end of the pool 2, and the lower base 15 of the pantograph 922 is slid into the guide hole of the bracket 16 at the lower end of the pool 2. Connect to. Furthermore, the tip of the pantograph link 12 is also connected to the upper plaque 18 and lower bracket 19 of the guide frame 17 so as to rotate or slide, respectively. The guide frame 17 is equipped with a cylinder (9) and a scraping plate 21 that slides up and down by the cylinder (9). The cylinder n for expanding and contracting the pantograph type link 12 is rotatably attached to the tip bracket B of the poom 2, and the cylinder rod is installed so that the leftover material 4 is placed in a position where the intermediate packet foil 3 on the base side of the pantograph type link 12 cannot reach. If it exists, the pantograph link 12 is extended by extending the rod of cylinder n. Next, extend the cylinder nod and lower the raking board 21, and make the raking board 21 face or bite into the leftover material 4. If the vertical stroke of the scraping board 21 is insufficient, the pool 2 itself may be raised and lowered.

Thereafter, when the mouth y toss of the cylinder n is shortened, the leftover material 4 that hit the scraping plate 21 is scraped up to a position where the packet foil 3 can reach. Therefore, the leftover material 4 is scooped up by the packet foil 3 and dispensed.

Normally, the pantograph type sink is contracted by the cylinder n, and the scraping plate 21 is raised by the cylinder force, and it is moved to the pool 2 side so that there is no protruding part as much as possible, so that it does not interfere with the work. Strain.

As described above, according to the present invention, the reclaimer itself can scrape up leftovers toward the packet foil, so even if the working radius of the reclaimer is small, the reclaimer itself can collect leftovers at positions where the packet foil cannot reach. You can obtain the effect of paying out.
