Background
Originally the excavators were manual, for over one hundred thirty years since invention and 2013, during which a gradual progression from steam driven bucket rotary excavators to electrically driven and combustion engine driven rotary excavators, fully automatic hydraulic excavators applying mechatronic technology was experienced. An excavator, also known as an excavating machine (excavating shovel), is an earth moving machine that excavates material above or below a bearing surface with a bucket and loads the material into a transport vehicle or unloads the material to a stockyard. The materials excavated by the excavator mainly comprise soil, coal, silt, soil subjected to pre-loosening and rocks. From the development of engineering machinery in recent years, the development of an excavator is relatively fast, the excavator becomes one of the most main engineering machinery in engineering construction, the excavator bucket tooth is mostly cast by sand, forged and cast and precisely cast, and an integrally-cut-formed tooth bucket is also adopted.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide an excavator bucket tooth device and a construction method.
In order to achieve the purpose, the invention adopts the technical scheme that: the excavator bucket tooth device comprises a bucket, bucket teeth are arranged at the lower end of the bucket, and a scraper blade is arranged at the back of each bucket tooth; the scraper is rectangular, a cutting edge is formed at the end of the scraper, an inclined surface is formed on one side, facing the bucket teeth, of the scraper, and the cutting edge is formed at the end of the inclined surface.
Preferably, the tip of the end of the scraper protruding the bucket tooth is 70mm to 100 mm.
Preferably, both sides of the scraper protrude from both sides of the bucket teeth, and the width of the protruding portion is not more than 60 mm.
Preferably, the chamfer angle of the chamfer is 30-60 °.
Preferably, the bucket tooth structure comprises a plurality of bucket teeth arranged side by side, and the scraper is welded to the backs of the bucket teeth.
Preferably, the scraper is a steel plate.
The construction method of the excavator bucket tooth is characterized by comprising the following steps:
(1) firstly, mounting a processed scraper at the end part of a bucket tooth of an excavator;
(2) according to the requirements of design drawings, a scraper plate is connected to two sides of the bucket teeth in an electric welding mode through an electric welding machine;
(3) when operating, an operator needs to operate according to the welding construction technical requirements to ensure full welding;
(4) after the construction is finished, the welding parts on the two sides of the bucket teeth are ground off by a polishing machine, and the steel plate is taken down, so that the bucket teeth are convenient to store and maintain.
Compared with the prior art, the invention has the following beneficial effects: according to the bucket tooth mark cleaning machine, the scraper is welded or anchored on the outer side of the bucket tooth part of the traditional excavator, the concave-convex part of the bucket tooth is changed into a plane structure by the scraper, the earth surface is smooth after the excavator is excavated, and the bucket tooth mark of the excavator cannot be remained, so that the problems that the bucket tooth mark is remained on the earth surface due to the concave-convex reason of the bucket tooth of the excavator and the bucket tooth mark still needs to be cleaned manually after the excavator is excavated are solved, and the bucket tooth mark cleaning machine is particularly suitable for the working conditions that water is quickly evaporated, the soil strength is higher, and the bucket tooth mark is difficult to be cleaned by a contact, such.
Drawings
The invention will be further described with reference to the accompanying drawings and examples, in which:
fig. 1 is a schematic view of the overall structure of the present invention.
The device comprises a bucket 1, a bucket 2, a bucket tooth 3, a scraper 4 and a cutting edge.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the excavator bucket tooth device of the present embodiment includes a bucket 1, a bucket tooth 2 is provided at a lower end of the bucket 1, and a scraper 3 is provided at a back of the bucket tooth 2; the scraper 3 is rectangular, a cutting edge 4 is formed at an end of the scraper 3, an inclined surface is formed on a side of the scraper 3 facing the bucket teeth 2, and the cutting edge 4 is formed at an end of the inclined surface.
Wherein: the tip of the end part of the scraper 3 protruding the bucket tooth 2 is 70-100 mm; two sides of the scraper 3 protrude out of two sides of the bucket teeth 2, and the width of the protruding part is not more than 60 mm; the cutting angle of the cutting inclined plane is 30-60 degrees; the bucket tooth 2 structure comprises a plurality of bucket teeth 2 which are arranged side by side, and the scraper 3 is welded to the backs of the bucket teeth 2; the scraper 2 is a steel plate.
The construction method of the excavator bucket tooth is characterized by comprising the following steps:
