Embodiment 1

[0034] Shovel is a machine used for digging and transporting soil. The soil scraped by the scraper can be automatically loaded into the bucket and transported away. It uses a bucket to excavate materials above or below the bearing surface, and load them into transport vehicles or unloaded to the earth-moving machinery of the stockyard. The excavated materials are mainly soil, coal, silt and pre-loose soil and rock.

[0035] When cleaning up some materials with high viscosity, such as soil and silt, they tend to stick to the blade. Squeezing slowly will cause the blade to become smaller. On the one hand, the shovel is not sharp and efficient, and on the other hand This will cause the scraped material to become smaller in volume and difficult to discharge. In the prior art, most of the manual cleaning is performed when not in use, which in turn causes the cleaning efficiency to decrease.

[0036] In view of the above problems, the present invention provides a self-cleaning mechanica...

Embodiment 2

[0047] The embodiment of the present invention is further defined on the basis of embodiment 1.

[0048] See Figure 3-5 A fixing plate 41 is fixed on the cleaning shovel structure 4 in cooperation with the shovel platform 42, and the cross section of the shovel platform 42 is triangular.

[0049] The shovel platform 42 is provided with a bottom support plate 46, and a bottom plate 43 is fixed at the bottom of the bottom support plate 46, a movable plate 44 is hinged on the bottom plate 43, and a buffer layer 45 is provided between the movable plate 44 and the bottom support plate 46 The buffer layer 45 is composed of a plurality of elastic members 47 distributed at equal intervals.

[0050] Furthermore, the movable plate 44 can change its angle through the buffer layer 45 so as to be suitable for cleaning residues of different thicknesses and improve the cleaning effect.

[0051] Optimally, the elastic member 47 is hinged between the movable plate 44 and the bottom support plate 46,...

Abstract

The invention belongs to the field of machinery, and particularly relates to a self-cleaning mechanical scraper knife of a scraping machine. The self-cleaning mechanical scraper knife comprises a scraper knife bucket with scraper teeth fixed at the front end and a cleaning shovel structure, wherein a side baffle is fixed on each of two sides of the scraper knife bucket, and the cleaning shovel structure is connected onto the side baffles in a sliding manner; a chain used for driving the cleaning shovel structure to slide along the surface of the scraper knife bucket is arranged in each side baffle, and the chains are in power transmission connection with a double-shaft motor; and a shovel table is arranged on the cleaning shovel structure. Furthermore, the double-shaft motor can drive thecleaning shovel structure to slide along the surface of the scraper knife bucket by means of the chains, automatic cleaning is achieved through utilizing the shovel table arranged on the cleaning shovel structure, on one hand, discharging is facilitated, on the other hand, the surface of the scraper knife bucket is kept clean, the scraper knife bucket is prevented from sticking to extrude materials, and normal operation of the scraper knife is not affected.
