Embodiment 1

[0022] Example 1: Please refer to Figure 1-4 , an excavator bucket that prevents bucket teeth from falling off, comprising a bucket body 1 and a fixing seat 2, the upper end of the bucket body 1 is fixedly connected with a connecting seat 3, the upper end of the bottom plate of the bucket body 1 is fixedly connected with a tooth plate 4, the tooth plate 4 The upper end is fixedly connected with a number of fixed seats 2, and the fixed seats 2 are detachably connected with bucket teeth 6 through pin shafts 5. The fixed seats 2 include the main body 21 of the fixed seat and the first groove 22. The first groove 22, the upper side of the left wall of the first groove 22 is fixedly connected with the first longitudinal block 23, and the lower end of the first block 23 forms a longitudinal first block with part of the left wall and part of the lower wall of the first groove 22. Two grooves 24, the right end of the main body 21 of the fixing seat are fixedly connected with the seco...

Embodiment 2

[0029] Embodiment 2: This embodiment is a further improvement of the previous embodiment: Considering that most of the slider 55 is exposed outside the ninth groove 53 under the action of the spring 54, it is difficult to pass through the eighth groove 610 when installing the pin shaft 5 The slider is pressed into the ninth groove 53 , and an obliquely downward guide groove is opened on the front wall of the eighth groove 610 on the upper side, and the slider 55 is pressed into the ninth groove 53 through the guide groove.

[0030] The working principle of the present invention is: when the bucket tooth 6 needs to be installed, the tooth seat 61 of the bucket tooth 6 and the fixed seat 2 are installed in cooperation with each other, the tooth seat 61 is pushed to the left, the first block 23 enters the fourth groove 65, The second block 25 enters the seventh groove 68, and the third block 64 enters the second groove 24. After the slider of the pin shaft 5 is pressed down, the p...

Abstract

The invention discloses an excavator bucket capable of preventing bucket teeth from falling off and belongs to the technical field of excavator accessories. The excavator bucket capable of preventing the bucket teeth from falling off comprises a bucket body and fixing seats; a connecting seat is fixedly connected to the upper end of the bucket body; a toothed plate is fixedly connected to the upper end of a bottom plate of the bucket body; a plurality of fixing seats are fixedly connected to the upper end of the toothed plate; the bucket teeth are detachably connected to the fixing seats through pin shafts; the fixing seats comprise fixing seat main bodies and first grooves; longitudinal first grooves are formed in the upper ends of the fixing seats; longitudinal first clamping blocks are fixedly connected to the upper sides of the left walls of the first grooves; the lower ends of the first clamping blocks form longitudinal second grooves together with partial left walls and partial lower walls of the first grooves; longitudinal second clamping blocks are fixedly connected to the right ends of the fixing seat main bodies; and the second clamping blocks and the first clamping blocks are the same in shape and size. Compared with the prior art, the excavator bucket capable of preventing the bucket teeth from falling off has the beneficial effects that the structure is simple, the use is convenient, the clamping teeth are firmly locked on the fixing seats through multiple locking mechanisms, the locking effect is good, and the clamping teeth are not prone to falling off.

Description

technical field [0001] The invention relates to the technical field of excavator accessories, in particular to an excavator bucket that prevents bucket teeth from falling off. Background technique [0002] A bucket refers to a bucket installed on an excavator, also called a bucket. According to the working method, it is divided into a backhoe bucket and a front shovel bucket. Generally, the backhoe bucket is commonly used. The bucket is a structural product, consisting of tooth seat plate, bottom plate, side plate, wall plate, lug plate, back plate, ear plate, ear sleeve, bucket teeth, tooth seat, guard plate or bucket angle and other spare parts Therefore, welding is the most critical manufacturing process of the bucket, and the welding quality directly affects the structural strength and service life of the bucket. [0003] Excavator bucket teeth are important consumable parts on excavators. Similar to human teeth, they are combined bucket teeth composed of tooth seats an...
