Abstract
The invention provides a device prevent front and rear buckets of a hydraulic excavator bucket from misplacing, relates to excavator buckets, and solves the technical problem that the conventional hydraulic excavator bucket lacks a device that prevents front and rear buckets from misplacing. The device comprises a bucket rear body and a bucket fore body which are connected through a hinged shaft, chamfers are formed in the two ends of bucket rear plate of the bucket rear body, so as to form a left slant and a right slant; the bucket fore plate of the bucket fore body at the chamfers in the two ends of the bucket rear plate project obliquely, and the slant of the obliquely projected bucket fore plate and the slant at the chamfers of the bucket rear plate are mutually matched. The device has the advantages of having a simple structure, being capable of preventing the bucket fore body and the bucket rear body from misplacing.
Description
Technical field
The present invention relates to the hydraulic excavator for mine scraper bowl, particularly a kind of hydraulic excavator for mine scraper bowl device of body dislocation behind front, the bucket that prevents from struggling against.
Background technology
Body and bucket precursor are installed to together by two pin joints behind the bucket of general large-scale mine Hydraulic Excavator Bucket.When opening bucket, body relatively rotates around pin joint with the bucket precursor behind the bucket.In the actual excavation process, can cause struggling against precursor and bucket the body bottom is relative afterwards and misplace because the inhomogeneous and scraper bowl of digging force is run into material in turning course, this will cause steel work to distort, and affect scraper bowl application life.
At present, the scraper bowl of the hydraulic excavator for mine device of rear body and the dislocation of bucket precursor that do not prevent from struggling against.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, provide a kind of Hydraulic Excavator Bucket prevent before and after the bucket body dislocation device, the scraper bowl that solves existing hydraulic excavator for mine there is no the technical problem of prevent from struggling against rear body and bucket precursor dislocation device.
The present invention is achieved through the following technical solutions.
Bucket body dislocation device before and after a kind of Hydraulic Excavator Bucket prevents comprises: by body behind the bucket of stud connection and bucket precursor, it is characterized in that: difference chamfering in base plate two ends behind the bucket of body behind the described bucket forms left tilted surface and right tilted surface; The bucket noseplate of described bucket precursor is the oblique protrusion in base plate two chamfer places after being positioned at bucket, and the inclined-plane at base plate chamfering place cooperatively interacts behind the inclined-plane of the oblique projection of described bucket noseplate and the described bucket.
The present invention has the following advantages and beneficial effect compared with the prior art:
1, simple in structure, rear body and the dislocation of bucket precursor can effectively prevent from struggling against;
2, body contacts with bucket precursor inclined-plane behind the bucket, and abrasion resistance is high, and the strength of corrected transposition is large.
Description of drawings
Fig. 1 is the structural representation of scraper bowl;
Fig. 2 is the structural representation that bucket-shaped attitude left by scraper bowl;
Fig. 3 is that bottom board inclined plane of the present invention cooperates schematic diagram;
Fig. 4 is schematic diagram of the present invention.
The present invention is further illustrated by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, 2, 3, bucket body dislocation device before and after a kind of Hydraulic Excavator Bucket prevents comprises: by body behind the bucket of stud connection 1 and bucket precursor 2, difference chamfering in base plate 1-1 two ends behind the bucket of body 1 forms left tilted surface A and right tilted surface B behind the described bucket; The bucket noseplate 2-1 of described bucket precursor 2 is the oblique protrusion in base plate 1-1 two chamfer places after being positioned at bucket, and the inclined-plane at base plate 1-1 chamfering place cooperatively interacts behind the inclined-plane of the oblique projection of described bucket noseplate 2-1 and the described bucket.
As shown in Figure 4, when bucket precursor 2 has dislocation tendency, bucket precursor dislocation direction is such as arrow left, because body is to the thrust of bucket precursor behind the bucket, at this moment can form oblique pressure Fn at contact position, inclined-plane B, Fn is opposite with bucket precursor dislocation direction at the component Fa of dislocation direction, and this component can make the bucket precursor recenter.Otherwise when bucket precursor 2 dislocation directions to the right the time, the normal force component of contact position, inclined-plane A can make the bucket precursor recenter.
To sum up, base plate 1-1 contacts by the inclined-plane behind bucket noseplate 2-1 and the bucket, when the bucket precursor has the skew dislocation to be inclined to, bucket body is pushed away to the center, reaches to prevent the purpose that misplaces.
