Abstract
The utility model discloses an improved welded structure of a tooth-lip plate of a bucket of a hydraulic excavator, which comprises the tooth-lip plate, a toothed sleeve, protective teeth, a wear plate, a tooth holder and the like. The welded structure is characterized in that the distance between the tooth holder and the protective teeth is reasonably arranged, the tooth holder and the protective teeth are welded for protecting the toot-lip plate for resisting the wear of the front surface, and the wear plate of 1-30mm is welded at the bottom of the bucket of the protective teeth for protecting the tooth-lip plate for resisting the wear of the back surface. Through the reasonable arrangement of the bucket teeth, the protective teeth and the wear plate at the bottom of the bucket, the tooth-lip plate of the bucket is made of common iron instead of abrasive material, thus ensuring the normal service life of the bucket and reducing the cost. The welded structure has the advantages of simple structure, low cost, obvious effect and the like.
Description
Technical field
The utility model relates to a kind of Hydraulic Excavator Bucket tooth labial lamina welding and improves structure, is applied to the replacement of dipper teeth labial lamina material.Improve the welded construction at dipper teeth labial lamina place, dipper teeth labial lamina material is changed to the Q345B steel by high-abrasive material, both guaranteed instructions for use, reduced cost again.
Background technology
The tooth labial lamina of Hydraulic Excavator Bucket very easily weares and teares when digging operation, can produce stress and concentrates when may wear under the to a certain degree effect at digging force this position, and the tooth labial lamina will be torn and cause scrapping of whole scraper bowl.So at present on the tooth labial lamina of Hydraulic Excavator Bucket except the welding bucket tooth or add weldering and protect tooth and protect the tooth labial lamina, the material that the tooth labial lamina adopts also requires to possess high strength, high-wearing feature and good welding performance.And this material price height not only, and buying also acquires a certain degree of difficulty.
Summary of the invention
The purpose of this utility model is to weld bucket tooth and adds weldering and protects tooth and protect the positive wearing and tearing of tooth labial lamina opposing, protects the bucket bottom of tooth and adds the wearing and tearing that the wear-resisting steel plate protection tooth labial lamina that weld 10～12mm is resisted the back adding weldering.The material of tooth labial lamina adopts Q345B.Guarantee by improving the welded construction of tooth labial lamina, to make the tooth labial lamina can use the Q345B steel under the scraper bowl prerequisite in application life.
Technical solution of the present utility model is such: comprise tooth labial lamina, tooth cover, protect tooth, wear strip, toothholder, it is characterized in that toothholder and protect tooth that distance is arranged, the welding toothholder protects tooth in tooth labial lamina front with adding to weld, and welds the wear strip of 1～30mm at tooth labial lamina back in the scraper bowl bottom of protecting tooth.
Protect tooth and toothholder on the tooth labial lamina.
The material of wear strip is the wearing plate material of a kind of 1～30mm, its be welded on the scraper bowl bottom and and manifold card protecting tooth.
The material of tooth labial lamina is to use the Q345B steel.
The utility model has the advantages that: adopt the power shovel of technique scheme, both can guarantee the normal application life of scraper bowl, reduced cost again.Have advantages such as simple in structure, with low cost, that effect is obvious.
Description of drawings
It is such that structure of the present utility model constitutes:
Fig. 1 is that the welding of the utility model dipper teeth labial lamina improves structural representation.
Fig. 2 is that the P of the utility model Fig. 1 is to partial view.
Fig. 3 is the A-A sectional view of the utility model Fig. 2.
Fig. 4 is the B-B sectional view of the utility model Fig. 2.
Among Fig. 1 to Fig. 4: tooth labial lamina (1), tooth cover (2), protect tooth (3), wear strip (4), toothholder (5).
The specific embodiment
Case study on implementation of the present utility model is such; in Fig. 4; Fig. 2, Fig. 3 and Fig. 4; reasonable Arrangement toothholder (5) and the distance of protecting tooth (3); weld toothholder (5) and add weldering and protect the wearing and tearing that tooth (3) is protected tooth labial lamina (1) opposing front, add the wearing and tearing that wear strip (4) the protection tooth labial lamina (1) that welds 1～30mm is resisted the back in the bucket bottom (Fig. 4) of protecting tooth (3).The material of wear strip (4) is 1～30mm, its be welded on the scraper bowl bottom and and manifold card protect tooth labial lamina (1) together protecting tooth (3), protect tooth (3) and toothholder (5) and go up the layout suitable distance at tooth labial lamina (1).Because this structure has effectively been protected tooth labial lamina (1) from front and bottom surface (with reference to Fig. 1), so tooth labial lamina (1) can select to use the Q345B steel.
Claims (4)
1. dipper teeth labial lamina welded construction, comprise tooth labial lamina, tooth cover, protect tooth, wear strip, toothholder, it is characterized in that toothholder (5) and protect tooth (3) that distance is arranged, weld toothholder (5) and add weldering and protect tooth (3), weld the wear strip (4) of 1～30mm at tooth labial lamina back in the scraper bowl bottom of protecting tooth (3) in tooth labial lamina (1) front.
2. according to the described dipper teeth labial lamina of claim 1 welded construction, it is characterized in that: protect tooth (3) and toothholder (5) on tooth labial lamina (1).
3. according to the described dipper teeth labial lamina of claim 1 welded construction, it is characterized in that: the material of wear strip (4) is the wearing plate material of a kind of 1～30mm, its be welded on the scraper bowl bottom and and manifold card protecting tooth (3).
4. according to the described dipper teeth labial lamina of claim 1 welded construction, it is characterized in that: the material of tooth labial lamina (1) is to use the Q345B steel.
