Description

Loader bucket

Technical Field

The present disclosure relates to a bucket, and more particularly, to a loader bucket.

Background

The loader bucket is an important accessory of a loader, the front edge of a bucket bottom plate of the bucket is a main cutting board, and bucket teeth are arranged on the main cutting board.

Once the loader bucket is designed and manufactured, its bucket capacity is determined. However, the loader is used for shoveling various materials, a bucket with the same specification is used for shoveling different materials, and the efficiency of the loader is different due to different materials. For some materials, if the bucket capacity is increased, the operation efficiency can be improved.

The bucket capacity of the existing bucket is increased, usually, a movable cutting board is installed on the bucket and located between two adjacent bucket teeth, the rear portion of the movable cutting board is fixed below a main cutting board of the bucket through bolts, and the front end of the movable cutting board protrudes out of the front edge of the main cutting board. The movable cutting board with the front end protruding out of the front edge of the main cutting board is equivalent to the main cutting board and extends forwards, so that the bucket capacity of the bucket is increased.

The fixed mounting mode of current activity cutting board has following not enough: the movable cutting board is arranged on the main cutting board, bolt holes are required to be arranged, and the arrangement of the bolt holes can weaken the strength of the main cutting board; the movable knife plate is fixedly installed by using the bolt, and the bolt is easy to loosen or cut off to cause the loosening of the movable knife plate; the movable cutting board is arranged below the main cutting board, so that the width of the movable cutting board in the front-back direction is larger, and the part (the part protruding out of the front of the main cutting board) for increasing the bucket capacity only occupies a small part, and the majority of the movable cutting board is arranged below the main cutting board and only has the connecting and installing effects.

Detailed Description

The following description of the embodiments refers to the accompanying drawings.

The first embodiment.

The loader bucket in this embodiment is shown in fig. 1 and 2. In this bucket, a plurality of bucket teeth 3 are attached to a main blade 2 of a bucket body 1 at intervals in the longitudinal direction thereof, a movable blade 4 is provided between two adjacent bucket teeth 3, and both ends of the movable blade 4 are connected to the bucket teeth, respectively.

As shown in fig. 3 and 4, a guide structure in the front-rear direction is provided on the side surface of the tooth 3, and the guide structure is constituted by a slide groove 31 provided on the side surface of the tooth. As shown in fig. 5, the end face of the movable knife board 4 is provided with a sliding structure, the sliding structure is composed of an elongated protrusion 41 arranged on the end face of the movable knife board and matched with the sliding slot 31, and the elongated protrusion 41 is embedded in the sliding slot 31 and can slide along the sliding slot 31. The arrangement positions of the guide structure on the side surface of the bucket tooth and the sliding structure on the end surface of the movable cutting board can be interchanged, namely, the sliding structure (strip-shaped bulge) is arranged on the side surface of the bucket tooth, and the guide structure (sliding chute) is arranged on the end surface of the movable cutting board. Before the bolt is not inserted between the movable cutting board 4 and the bucket tooth 3, the movable cutting board 4 can slide in the front-back direction of the bucket tooth (the direction pointed by the tooth tip of the bucket tooth is the front direction) through the matching of the sliding structure and the guide structure on the bucket tooth.

As shown in fig. 3 and 4, a notch is provided on a side surface of the tooth 3, the tooth upper notch 32 penetrates the side surface of the tooth 3 in the vertical direction, and the tooth upper notch 32 is groove-shaped, wide in the vertical direction, and step-shaped. As shown in fig. 5, a notch 42 is also provided at an end of the movable cutting board 4, the notch 42 on the movable cutting board and the notch 32 on the bucket tooth form a vertical pin hole, and the position locking between the movable cutting board 4 and the bucket tooth 3 can be realized by inserting the bolt 5 into the vertical pin hole.

As shown in fig. 6, the plug 5 includes a pin body 53 having a rectangular parallelepiped shape and provided with a receiving space, a bayonet 52 installed in the receiving space, and an elastic body 51; one end of the click pin 52 protrudes from the surface of the click body 53, and the other end is connected to the elastic body 51. As shown in fig. 3 and 4, a slot 33 matched with the end of the pin body is arranged on the side wall of the notch 32 on the tooth.

As shown in fig. 7, in the present embodiment, the movable cutting board 4 is installed, and slides backwards through the sliding structure (elongated protrusion) on the movable cutting board from the front end of the guide structure (sliding chute) on the side surface of the bucket tooth until the rear side surface 43 of the movable cutting board 4 contacts with the front edge of the main cutting board 2, and at this time, the notch 32 on the bucket tooth and the notch 43 on the movable cutting board cooperate to form a vertical pin hole. The plug pin 5 is inserted into the vertical pin hole, and after the plug pin 5 is inserted in place, the bayonet 52 in the plug pin 5 protrudes out of the surface of the pin body 53 under the elastic force of the elastic body 51 and is embedded into the bayonet 33 on the side wall of the notch on the bucket tooth, so that the pin body 53 is prevented from falling off. When the movable knife board 4 is detached, the pin 5 is ejected out of the top end of the vertical pin hole from the lower part of the upper notch 31 of the bucket tooth by using the ejector pin, and after the pin is taken out of the vertical pin hole, the movable knife board slides forwards to enable the guide structure of the side face of the bucket tooth of the sliding structure sliding groove to realize the separation of the movable knife board and the bucket tooth.

In this embodiment, the movable cutting board 4 depends on the sliding structure of its tip and the guide structure cooperation on the bucket tooth and fixes on the bucket tooth under the effect of bolt, avoids using bolt locking to fix to can avoid causing the pine problem of taking off of movable cutting board because of the bolt pine takes off or cuts cracked problem, thereby improve the reliable and stable nature of movable cutting board installation.

Example two.

As shown in fig. 8 and 9, the difference of the bucket of the present embodiment from the first embodiment is the movable blade 4. In this embodiment, the rear portion of the movable cutting board 4 has an overlapping portion 44 overlapped with the main cutting board, the overlapping portion 44 is provided with a mounting hole 45, and correspondingly, a through hole 21 is provided on the main cutting board, after the movable cutting board 4 is mounted according to the first embodiment of the movable cutting board, the mounting hole 45 on the movable cutting board is exactly aligned with the through hole 21 on the main cutting board, and the bolt 6 passes through the mounting hole 45 and the through hole 21 to cooperate with a nut to lock and fix the movable cutting board 4 and the main cutting board 2.

In this embodiment, the movable cutting board 4 is connected with the guide structure on the side surface of the bucket tooth through the sliding structure at the front part and is fixed through the bolt, and the part of the rear part of the movable cutting board, which is vertically overlapped with the main cutting board, is fixedly connected with the main cutting board through the bolt, so that the installation firmness strength of the movable cutting board is further enhanced. In this embodiment, the movable blade can be kept from loosening even if the bolt loosens or breaks.

In this embodiment, the overlapping portion 44 of the movable blade and the portion of the movable blade protruding from the front edge of the main blade are stepped, and the vertical surface 46 of the step contacts against the front edge of the main blade 2, so that the movable blade can bear larger acting force during the operation of the bucket.
