CN2424238Y - Shovel blade of carry scraper - Google Patents

Abstract

The utility model discloses a shovel blade of a carry scraper. A single row flat blade which is arranged on the existing shovel blade is improved into a two row jagged blade. The jagged blade can be used for cutting and conveying soil in a time sharing and severing way. The utility model has the advantages that the embedded area of the blade is reduced, the resistance of the cutting and the conveying for the soil is lowered, the traction force is saved, the time for scraping is shortened, and the production efficiency is improved. The scraping and the conveying of the oil are tested by a homogeneous earthwork with the same labor and the same distance, the diesel oil can be saved by 120 grams in every one cubic meter soil, and the effect of energy saving reaches more than 25%.

Description

Scraper blade

The utility model provides a kind of digging element of scraper, exactly is a kind of improved scraper blade.

Perching knife is as the groundwork device of scraper, and its structure and performance are directly connected to the operating efficiency and the energy-saving effect of scraper; At present, perching knife blade on the scraper of home and abroad is single flat, blade integral body was buried when this perching knife was cut the earth, because whole blade lengths is longer, it is bigger to cut soil, when soil shovel resistance, and slow, the inefficiency of shovel running speed degree is especially to the shovel haul volume engineering of harder soil property, the machine power power consumption is more serious, and fuel consumption is big.

The purpose of this utility model is to provide a kind of sectional to cut the scraper blade of soil, shovel soil, cuts shovel by the segmentation of perching knife, reaches remarkable energy conservation and consumption reduction effects.

For achieving the above object, the single flat blade sheet that the utility model will have perching knife now is improved to front and back two gang saw tooth-like formation blades, and front-seat tooth top blade is provided with toothrow root blade space, back.

Because two gang saw dentation settings before and after blade is taked, but soil, shovel soil are cut in front and back two row's blade timesharing, segmentation, reduced the area that buries of blade, greatly reduce cut, the resistance of muck haulage, save tractive force, shortened the shovel soil time, improved production efficiency, through similar ground works, same worker, with the shovel muck haulage test of distance, each cubic metre soil is saved diesel oil 120 grams, and energy-saving effect reaches more than 25%.

Description of drawings:

Fig. 1 is the utility model embodiment front view;

Fig. 2 is the left view of Fig. 1.

The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1, have six fixing holes 2 on the perching knife mainboard 1, so that perching knife is fixed on the scraper base plate, the blade of two gang saw tooth-like formation before and after the perching knife front end is provided with, front-seat tooth top blade 3 is provided with toothrow root blade 4 spaces, back, but front and back two row's blade time processing moulding, also can on existing flat blade sheet perching knife, stretch out the flat blade sheet forward and weld several independent blades of system at interval as the tooth top blade, two row's blade face all adopt the TD60 high-hardness wear-resisting bead welding rod to do surface overlaying and handle, and make knife face hardness reach HRC57-62; As shown in Figure 2, the angle of penetration of two row's blades is chosen as 30 °-35 °.

Claims (1)

1, scraper blade, the perching knife mainboard is provided with fixing hole, and front end is provided with blade, it is characterized in that: blade is front and back two gang saw tooth-like formation, and front-seat tooth top blade is provided with toothrow root blade space, back.
