Description

Technical Field

[0001] The utility model discloses a bucket mechanism with an axle pin and an axle sleeve, belonging to the field of excavator parts. Background Art

[0002] Bucket, also called shovel bucket, is a structural product. It is composed of tooth seat plate, bottom plate, side plate, wall plate, ear plate, back plate, bucket ear plate, bucket ear sleeve, bucket teeth, tooth seat, guard plate or bucket angle and other parts. Therefore, welding is the most critical manufacturing process of bucket. The welding quality directly affects the structural strength and service life of the bucket. The bucket is connected to the bucket and connecting rod through the bucket pin and connecting rod pin. Replacing the bucket is actually to remove the bucket pin and connecting rod bucket cylinder pin, remove the original bucket, and then connect other buckets or working devices with the bucket and connecting rod with the bucket pin and connecting rod pin, which is the process of installing the bucket pin and connecting rod pin. The shortcomings of the current technology that need to be optimized are:

[0003] The bucket axle pin and bucket axle sleeve of a conventional bucket are the key connecting parts of the bucket mechanism assembly. They bear rigid force and have a stable flipping degree of articulation. They are easily affected by the friction of muddy soil, which slows down the flipping and wears the ear holes of the bucket connection and the outer surface of the bucket axle pin and bucket axle sleeve itself, resulting in insufficient durability of the bucket. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a bucket mechanism with an axle pin and axle sleeve to solve the problem that the bucket axle pin and bucket axle sleeve of a conventional bucket are key connecting components of the bucket mechanism assembly, and the rigid force they bear and the stable flipping degree of the hinge are easily affected by the friction of muddy soil, which slows down the flipping, and wears the ear holes of the bucket connection and the outer shell surfaces of the bucket axle pin and the bucket axle sleeve themselves, resulting in insufficient durability of the bucket.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a bucket mechanism with an axle pin and axle sleeve, whose structure includes: a bucket axle pin, an upper lifting ear frame, a bucket axle sleeve, a connecting fastener, a reinforcing rib plate, and a bucket groove. The bucket axle pin and the bucket axle sleeve are inserted together and the axes are colinear. The bucket axle sleeve is provided with more than two and is respectively installed on the left and right sides of the upper lifting ear frame. The upper lifting ear frame is installed on the top of the connecting fastener. The reinforcing rib plate is provided with two and is welded to the top of the middle section of the bucket groove. The ear frame is buckled together with the top of the bucket groove through connecting fasteners. The bucket axle pins are provided with more than two and are respectively installed on the left and right sides of the outside of the upper lifting ear frame. The bucket axle pin is provided with an air hole, an axle pin column rod, and a rubber gasket. The air hole is provided with two and both are installed at the upper left corner of the axle pin column rod. The air hole and the axle pin column rod are an integral structure and are interconnected. The axle pin column rod is installed on the top of the rubber gasket and the axes are in line. The axle pin column rod and the rubber gasket are nested as a whole. The axle pin column rod and the bucket axle sleeve are inserted together and the axes are in line.

[0006] To optimize the above technical solution, further measures are taken:

[0007] As a further improvement of the present invention, the bucket shaft sleeve is composed of a mud scraper screen hole, a shaft ring sleeve groove, and a cylindrical shaft sleeve seat. The mud scraper screen holes are provided with more than two and are distributed in a circular dot matrix pattern inside the shaft ring sleeve groove. The shaft ring sleeve groove and the cylindrical shaft sleeve seat are nested as one and the axes are colinear.

[0008] As a further improvement of the utility model, the scraper screen hole is a hole groove structure with an oblique tooth pattern and through holes distributed in a circular dot matrix, which facilitates the oblique tooth pattern scraper to remove silt on the shaft pin and sleeve ends, and improves the operating effect of the self-adaptive bucket cleaning connector.

[0009] As a further improvement of the present invention, the shaft ring sleeve groove is a ring sleeve structure with a wide bearing ring and a narrow bearing in a gradient support, which facilitates the interlocking operation effect of sleeve-connecting the shaft pin and the shaft sleeve seat to form a composite connecting piece.

[0010] Beneficial Effects

[0011] The utility model discloses a bucket mechanism with an axle pin and axle sleeve. Workers assemble the air hole of the bucket axle pin and the axle pin column rod, insert the rubber gasket, and then cross the axle pin column rod to connect the axle ring sleeve groove of the bucket axle sleeve on both sides of the upper lifting ear frame and buckle it with the column shaft sleeve seat, so that the connecting fasteners buckle the reinforcing rib plate and the bucket groove to realize the assembly operation effect of the bucket. In the process of bucket working, the scraping mud operation effect of preventing the internal silt of the bucket axle pin and the bucket axle sleeve is obtained through the scraping mud sieve hole.

[0012] The advantages that can be achieved after the operation of the utility model are:

[0013] The bucket axle pin and bucket axle sleeve are matched with each other through flexible latch-type bucket axle pin and bucket axle sleeve, and the long axle pin column rod is matched to form a composite wrapped sleeve structure of a shaft ring sleeve groove and a column shaft sleeve seat, so that the overall bucket axle pin and bucket axle sleeve are connected to the lifting ear frame of the bucket trough more flexibly and smoothly, and through the mud scraping screen hole, the effect of efficient mud discharge and flexible and durable operation is achieved.
