Abstract
A bucket tooth of a bucket excavator comprises a mounting part and a working part; the mounting part is clamped with the working part and is fixed through a pin shaft; the installation department adopts the casting to make, the work portion adopts the forging to make. The utility model provides a pair of bucket tooth of bucket machine can reduce processing cost and replacement cost.
Description
Technical Field
The utility model relates to a bucket tooth, especially a bucket tooth of bucket excavator.
Background
The bucket teeth of the bucket excavator are used for excavating hard objects such as stones and soil and protecting the bucket from being damaged. The existing bucket teeth are generally of an integral structure. The damaged part of the bucket tooth is mainly the tooth tip, and the part is easy to bend and deform during digging and often needs to be replaced after continuous working for one day. Due to the adoption of integral processing, when the bucket teeth are damaged, the bucket teeth need to be integrally replaced, so that the cost is greatly increased.
In addition, the existing bucket teeth are integrally forged or cast into a whole, so that the integral forging cost is very high, the integral casting is not wear-resistant, and the bucket teeth are easy to break. (now the back is changed into casting, the front tooth point is changed into forging, wear-resisting, difficult rupture).
Disclosure of Invention
The utility model aims to solve the technical problem that a bucket tooth of a bucket excavator is provided, the processing cost can be reduced and the wear resistance can be improved.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
a bucket tooth of a bucket excavator comprises a mounting part and a working part; the mounting part is clamped with the working part and is fixed through a pin shaft; the mounting part is made by casting, and the working part is made by forging; the hinge pin comprises a positive thread section and a negative thread section which are opposite in turning direction, the positive thread section is inserted into a first rectangular hole of the negative thread section through a rectangular block, locking blocks are arranged on the positive thread section and the negative thread section, the front part of each locking block is a second rectangular block, the rear part of each locking block is a dovetail block, a small-section thread inner hole is formed in the front part of each locking block, a through hole is formed in the rear part of each locking block, the positive thread section or the negative thread section is in threaded connection with the thread inner hole, and a gap is kept between the positive.
The lateral wall of the working part is provided with a convex strip extending from the tooth tip to the tooth tail, and the convex strips are evenly arranged in the circumferential direction.
The installation part is of a hollow structure.
The utility model relates to a bucket tooth of bucket excavator has following technological effect: through setting up bucket tooth detachably into two parts, and two parts adopt different processing methods preparation respectively, not only save the cost greatly for processing producer like this, saved the cost moreover for the user, and improve wear resistance.

In the figure: the mounting part 1, the working part 2, the pin shaft 3, the convex strip 4, the regular thread section 5, the reverse thread section 6, the first rectangular block 7, the locking block 8, the second rectangular block 9 and the dovetail block 10,
Detailed Description
As shown in fig. 1-3, the bucket tooth of the bucket excavator changes the integral structure of the existing bucket tooth into a detachable structure, and comprises an installation part 1 and a working part 2, wherein the installation part 1 is clamped with the working part 2 and is fixed through a pin shaft 3. Thus, when the working part 2 is damaged by bending deformation or the like, the working part 2 can be directly removed and replaced, and the overall cost saving accounts for 70% of the total cost.
The mounting part 1 is made by casting, and the working part 2 is made by forging. Because the main part of bucket tooth adopts the casting, can simplify the course of working like this, save cost, and the work portion 2 adopts forging to make, multiplicable wearability. The cost can be reduced on the premise of optimizing the bucket tooth performance by combining two different processing methods.
The 2 lateral walls of working portion have by the prong to the convex strip 4 of tooth tail extension, 4 circumference evenly arranged of convex strip and smooth transition connection each other. The convex strips 4 are adhered or clad on the surface of the working part 2 by adopting an alloy wear-resistant layer. The alloying element is silicon. Therefore, the surface hardness of the working part of the bucket tooth is improved, and the surface abrasion of the bucket tooth is reduced when the bucket tooth repeatedly cuts and impacts materials.
In addition, the mounting portion 1 has a hollow structure, thereby saving material. The front end of the mounting part 1 is provided with a mounting hole, so that the mounting part is conveniently connected with the tooth holder.
In order to facilitate the rapid installation and disassembly of the pin shaft 3, the pin shaft is divided into a regular thread section 5 and a reverse thread section 6 with opposite rotation directions, the regular thread section 5 is inserted into a rectangular hole of the reverse thread section 6 through a first rectangular block 7, and the regular thread section 5 and the reverse thread section 6 are rapidly inserted. The corresponding installation part 1 and the working part 2 are provided with through holes, and when the installation part 1 is clamped with the working part 2, the through holes of the installation part 1 and the working part are just right opposite. The positive thread section 5 and the negative thread section 6 are both provided with locking blocks 8, the front parts of the locking blocks 8 are second rectangular blocks 9, the rear parts of the locking blocks are dovetail blocks 10, the front parts in the locking blocks 8 are provided with small sections of thread inner holes, the rear parts of the locking blocks are provided with through holes, the positive thread section 5 or the negative thread section 6 is in threaded connection with the thread inner holes, and the positive thread section 5 or the negative thread section 6 is in clearance with the through holes. During connection, the two locking blocks 8 are respectively in threaded connection with the regular thread section 5 and the reverse thread section 6, and then the two assemblies are respectively inserted from the left and right sides of the through holes of the installation section 1 and the working section 2, so that the first rectangular blocks 7 and the rectangular holes of the regular thread section 5 and the reverse thread section 6 are inserted, and the locking blocks 8 are opposite to the through holes of the installation section 1 and the working section 2. Then the positive thread section 5 or the negative thread section 6 is rotated, and the two locking blocks 8 approach and translate into the through hole of the working part 2. And finally, the inclined planes of the two locking blocks 7 are respectively locked with the upper inclined plane and the lower inclined plane of the left through hole and the right through hole of the mounting part 1 in a friction mode, and when the locking blocks need to be detached, the locking blocks rotate reversely.
