Detailed Description
the following is a specific embodiment of the present invention, which will be further described with reference to the accompanying drawings.
Referring to fig. 1 to 4, in the quick-release connection structure of the engineering machinery, a mounting plate 1 is welded on the engineering machinery, and fixing blocks 2 are uniformly distributed on the mounting plate 1. The upper surface of the fixed block 2 is provided with a bolt placing groove 2-1, and the bolt placing groove 2-1 is an open U-shaped shaft hole; two sides of the fixed block 2 are provided with symmetrical sliding strips protruding out of the side surfaces of the fixed block 2. The inner side of the bucket tooth is provided with a through groove 10, a fixed block placing groove 10-1 is arranged in the through groove 10, and the inner wall of the fixed block placing groove 10-1 is provided with a sliding groove matched with the sliding strip. The bucket teeth are buckled on the mounting plate 1 through the through grooves 10, and the fixing blocks 2 are located in fixing block placing grooves 10-1 in the through grooves 10. The surface of the bucket tooth is provided with a mounting hole 10-2 communicated with a fixed block placing groove 10-1.
as shown in conjunction with fig. 7 and 8;
When the assembly is carried out,
Firstly, a horizontal rod of an L-shaped bolt 6 penetrates through the mounting hole 10-2, and then the horizontal rod is rotated to be horizontal until a vertical rod of the L-shaped bolt 6 is mounted in the mounting hole 10-2; the mounting hole 10-2 on the bucket tooth is conical, the end part of the vertical rod of the L-shaped bolt 6 is provided with a conical nut, and the nut is embedded into the conical mounting hole 10-2 in a matching manner so as to limit the bucket tooth to move in the vertical direction; the mounting structure of the L-shaped bolt 6 ensures that the nut is not exposed, prevents the L-shaped bolt 7 from being worn in the working process and prolongs the service life;
secondly, buckling the bucket teeth on the front side of the mounting plate 1 through the through grooves 10 and pushing the bucket teeth backwards, wherein the horizontal rods of the L-shaped bolts 6 are positioned in the bolt placing grooves 2-1 to play a guiding role and limit the left and right swinging of the bucket teeth;
Finally, the end part of the horizontal rod of the L-shaped bolt 6 extends out of the rear end of the fixed block 2; the opposite-top nut 9 is installed at the end part of the horizontal rod through threaded connection, two gaskets 7 are arranged on the inner side of the opposite-top nut 9, and an elastic element 8 is installed between the two gaskets 7, so that the purposes of looseness prevention and buffering are achieved. In the process of digging or shovel loading operation, when a hard object is met, the bucket teeth and the cutter plate 5 can generate displacement of a certain distance under the action of the elastic element 8, so that the bucket teeth and the cutter plate are not damaged when being impacted strongly.
Similarly, as shown in fig. 6 in combination with fig. 5, the bucket teeth include a middle bucket tooth 3 and side bucket teeth 4, a cutting board 5 is arranged between adjacent bucket teeth, and two sides of the cutting board 5 are in contact with the side portions of the bucket teeth. The bucket teeth and the cutting board are of the split structure, when the bucket teeth and the cutting board break down and need to be replaced, the whole bucket teeth and the whole cutting board do not need to be replaced, and cost is saved.
The cutting board 5 is fixedly arranged on the mounting plate 1 and the fixing block 2 by adopting a structure similar to the bucket teeth, and the assembly mode is the same. The differences are as follows: the cutting board 5 is provided with two sliding grooves 10-1, each cutting board 5 is fixedly connected with the two fixed blocks 2, and the cutting board 5 can be prevented from swinging left and right in the operation process through the two fixed blocks 2; the fixed block 2 connected with the cutting board 5 and the fixed block 2 connected with the bucket tooth are not on the same straight line any more, and are staggered by a certain distance from front to back, so that the front end of the cutting board is shorter than the bucket tooth, and the digging or shoveling is facilitated.
Preferably: the front side of the mounting plate 1 is provided with an outer inclined plane, the bottom of the bucket tooth through groove 10 is provided with an inner inclined plane which is matched with the outer inclined plane of the mounting plate 1 relatively, and a bulge which is propped against the outer inclined plane of the mounting plate 1 is fixed on the inner inclined plane of the bucket tooth through groove 10. The protruding setting in bucket tooth logical groove 10 bottom can prevent to appear blocking phenomenon in the installation, has solved the difficult problem that drops from the mounting panel of bucket tooth and cutting board when needing the maintenance.
preferably: the surface of the fixed block 2 is provided with bosses which are respectively arranged at the two sides of the bolt placing groove 2-1, and the inner side surfaces of the bosses are inclined planes; the fixed block placing groove 10-1 is provided with a positioning hole matched with the boss, the boss is inserted into the positioning hole in a matched mode, and the bottom of the positioning hole is provided with an inclined plane matched with the inclined plane of the boss; the structure has the advantages that the front and back installation positions of the bucket teeth and the cutter plate can be limited, and the positioning effect is achieved.
The present invention has been described above by way of example, but the present invention is not limited to the above-described specific embodiments, and any modification or variation made based on the present invention is within the scope of the present invention as claimed.
