Electric scraper is a kind of scraping and transporting machine that uses bucket to shovel soil and load broken soil into bucket for transportation, which can complete the comprehensive operation of shoveling, loading, transporting, unloading and layered filling and partial compaction. It is suitable for leveling the site of railroad, road, water conservancy, electric power and other projects. The shovel has the advantages of simple operation, not restricted by terrain, independent work, fast driving speed and high production efficiency. It is suitable for one to three types of soil, such as shoveling more than three types of soil, need to loosen the soil in advance. At present, the widely used scrapers in the market are divided into two kinds of internal combustion scrapers and electric scrapers. Internal combustion scrapers are suitable for well-ventilated operating environment and have the characteristics of flexibility and efficiency; electric scrapers are more environmentally friendly and pollution-free. The characteristics, structure, classification, development achievements, operation process, safety procedures, etc. are introduced in detail.

Electric scraper, belongs to a kind of integrated machine for shoveling and transporting soil. The main point of the invention is the design of a bucket with shoveling mechanism consisting of bucket body, shovel blade, earth breaking knife, rotating stopper, sliding stopper and a support mechanism consisting of front strut, 2 side struts and stopper strut. The rotating baffle and sliding baffle are set at the opening of the bucket body, and they are connected by hinges, and the two ends of the hinges are inserted into the slide groove at the front of the bucket body and can be moved along the slide groove. The shovel blade is welded to the front end of the bucket body, and the earth breaking knife is welded to the shovel blade. The support mechanism is used to control the lift of the sliding stopper and the rotating stopper. The invention has a simple structure, high construction efficiency, and is suitable for river dam construction and
After the flood to remove silt, etc.

4 issues that need attention in the electric scraper industry

The uncertainty of the domestic and international economic environment has caused fluctuations in the development of China's construction machinery industry, which also includes the scraper and earth-moving machinery industry. But also for the healthy, sustainable and stable development of the industry sounded the alarm, let us wake up to the development process needs to face the problem, China's earth-moving machinery industry has come to a strategic transformation, innovation and change of the key period.

(1) the business philosophy, development mode and model needs to be changed.

At present, some enterprises still exist simply to pursue market share and sales volume, has not paid enough attention to product quality and added value, keen to expand production capacity and scale to compete with the strength of enterprises, rather than focus on the development of the overall comprehensive strength. As a traditional product with a long history of development of China's construction machinery products, shovel and transport machinery has experienced several ups and downs, has been tested, has formed a full range of products, is a relatively stable industry, but at the same time, the lack of product quality and technological innovation capabilities have gradually become the industry's development drawbacks.

　　
(2) low profit operation still exists, the development of enterprises is not enough energy.

Shovel transport machinery industry, especially the loader industry has experienced a painful price war in the 1990s, resulting in a continuous decline in profit levels, and ultimately make the industry in a long-term low profit or even zero profit running state, become the shovel transport machinery industry can not say the pain, but also led to the development of the production enterprises serious lack of energy, it is difficult to invest more funds in technology research and development, the formation of a vicious circle.

(3) independent innovation ability is not enough, large tonnage product technology bottleneck still needs to break through.

　　
Although some of the leading enterprises in the shovel and earth moving machinery industry in the field of major equipment to obtain technical breakthroughs, but from the perspective of the industry as a whole, the overall technical strength of the industry is still at a low level, product reliability needs to be improved, especially in the field of large tonnage products more still in the blank.

(4) standards can not meet the requirements of standardization and enhance the development of the industry.

　
National / industry standard is an important indicator of the overall technology and manufacturing level of an industry, the strategic significance of the standard is much higher than its guiding significance, often who has mastered the standard who has mastered the right to speak in the market. As China's construction machinery products and foreign advanced level compared to a certain gap in the development of standards, due to more consideration of the actual situation in the country, the level of standards developed relatively low, can not play a role in regulating and supporting the development of the industry.

Of course, in addition to the above problems, there are many problems, such as the sharp contradiction between supply and demand, energy problems began to affect the order of production and operation of enterprises, increased costs reduce the economic efficiency of enterprises, low-level duplication of investment in construction and overcapacity risks exist, increased pressure on accounts receivable, the supply of high-end components, industry self-regulation and the export environment faced by many difficulties, etc., are we need to seriously face and To solve the problems, and to solve these problems, all parties need to work together to ultimately achieve a win-win situation.
