For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0026] Please refer to Figure 1-6 In one embodiment of a front-end excavator bucket of the present invention, the front-end excavator bucket includes a bucket body 1, a connecting assembly 2, a connecting rod body 3, a front excavator frame body 4 and an oil cylinder 5, wherein the upper end of the bucket body 1 is detachably and rotatably connected to one end of the connecting rod body 3 through the connecting assembly 2, and the lower end of the bucket body 1 is detachably and rotatably connected to the front end of the front excavator frame body 4 through the connecting assembly 2, and a bucket tooth 11 is installed at the front end of the bucket body 1; the other end of the connecting rod body 3 is rotatably connected to the middle part of the front excavator frame body 4 biased towards the bucket body 1, one end of the oil cylinder 5 is rotatably connected to the middle part of the connecting rod body 3, and the other end of the oil cylinder 5 is rotatably connected to the rear end of the front excavator frame body 4.

[0027] When this embodiment is in use, the oil cylinder 5 is controlled to extend and retract to drive the connecting rod body 3 to rotate around the connection between the connecting rod body 3 and the front digging frame body 4. The rotation of the connecting rod body 3 drives the bucket body 1 to rotate up and down around the connection between the lower end of the bucket body 1 and the front end of the front digging frame body 4. The bucket body 1 rotates up and down to perform excavation operations through the bucket teeth 11; when the bucket body 1 wears during operation, the connecting component 2 can be removed to release the restriction on the bucket body 1, and then the bucket body 1 can be replaced, and then the connecting component 2 can be reinstalled.

[0028] Specifically, the connecting assembly 2 includes a pin 21 and an annular pin 22. The pin 21 passes through the bucket body 1 and the connecting rod body 3 / front digging frame body 4, so that the upper and lower ends of the bucket body 1 are respectively rotatably connected to the two pins 21; the annular pin 22 passes through the end of the pin 21 to cooperate with the head of the pin 21 to limit the bucket body 1 from being separated from the connecting rod body 3 / front digging frame body 4; when in use, align the connecting holes of the upper and lower ends of the bucket body 1 with the connecting rod body 3 and the front digging frame body 4, insert the two pins 21 into the aligned connecting holes respectively, and then insert the annular pin 22 into the pin hole at one end of the pin 21 to cooperate with the head of the other end of the pin 21 to limit the bucket body 1 from being separated from the connecting rod body 3 / front digging frame body 4, thereby completing the installation of the bucket body 1; when disassembling, remove the pin 21 and the annular pin 22, and then remove the bucket body 1.

[0029] More specifically, the above-mentioned connecting assembly 2 also includes a screw 23; the rod end of the screw 23 passes through the inner hole of the annular pin 22 and is threadedly connected to the bucket body 1. By tightening the screw 23, the head end of the screw 23 cooperates with the bucket body 1 to clamp the annular pin 22, so as to limit the annular pin 22 from being separated from the pin shaft 21, thereby further limiting the pin shaft 21 from being separated from the connecting rod body 3 / front digging frame body 4, thereby improving the restriction effect on the bucket body 1; when disassembling, first loosen the screw 23 and then remove the pin shaft 21 and the annular pin 22.

[0030] In addition, considering that the bucket teeth 11 are in intense friction with the material for a long time and are easily worn out; and the cost of replacing the entire bucket body 1 is relatively high, based on this, the bucket teeth 11 can be set to be detachably connected to the front end of the bucket body 1. Specifically, a strip-shaped notch is provided at one end of the bucket teeth 11, and the bucket teeth 11 can be sleeved on the front end of the bucket body 1 through the strip-shaped notch; there are two through holes penetrating the strip-shaped notch on the bucket teeth 11, and a bolt is provided in each through hole. The bolt passes through the bucket body 1 and is threadedly connected to a nut. The bucket teeth 11 can be detachably connected to the front end of the bucket body 1 by tightening or loosening the bolts. In this way, only the severely worn bucket teeth 11 need to be replaced, and there is no need to replace the entire bucket body 1, thereby reducing construction costs.

[0031] Specifically, a mounting plate 41 can be welded to the rear end of the front excavation frame 4, a mounting hole 411 is opened on the mounting plate 41, and a reinforcing rib 42 is welded at the angle between the mounting plate 41 and the front excavation frame 4 to reinforce the mounting plate 41. The mounting plate 41 can be installed on engineering machinery such as tractors and loaders by bolting with the mounting hole 411, thereby improving the scope of use.

[0032] Specifically, the connecting rod body 3 includes a cross bar 31 and an arc-shaped rod 32 connected end to end; the upper end of the bucket body 1 is detachably rotatable and connected to the end of the cross bar 31 away from the arc-shaped rod 32; the end of the arc-shaped rod 32 away from the cross bar 31 is detachably rotatable connected to the middle part of the front excavation frame body 4, biased toward the bucket body 1, through a connecting assembly 2; one end of the oil cylinder 5 is detachably rotatable connected to the connection between the cross bar 31 and the arc-shaped rod 32 through a connecting assembly 2. The detachable rotatable connection method of the connecting assembly 2 used in the connecting rod body 3 is the same as the detachable rotatable connection method of the connecting assembly 2 used in the above-mentioned bucket body 1, the difference being that the connecting assembly 2 of the connecting rod body 3 will have a washer 61 padded on the end of the pin shaft 21 to distribute the load, and a sleeve 6 will be placed on the pin shaft 21 to reduce friction. By designing the connecting rod body 3 as a detachable connection method, it can be replaced separately when damaged, without having to replace the entire front end bucket, thereby reducing costs.

[0033] More specifically, two groups of cross bars 31 and arc bars 32 can be symmetrically provided, and the two groups of cross bars 31 and arc bars 32 are respectively arranged on both sides of the front excavation frame body 4 to improve the overall stability.

[0034] The usage method or working principle of the utility model is as follows:

[0035] First, the mounting plate 41 can be installed on the engineering machinery by bolting together the mounting hole 411, and then the oil inlet pipe 51 and the oil outlet pipe 52 on the oil cylinder 5 are connected to the hydraulic system on the engineering machinery. On the operating platform, the hydraulic system is used to control the extension and retraction of the oil cylinder 5 to drive the connecting rod body 3 to rotate around the connection between the connecting rod body 3 and the front digging frame body 4. The rotation of the connecting rod body 3 drives the bucket body 1 to rotate up and down around the connection between the lower end of the bucket body 1 and the front end of the front digging frame body 4. The bucket body 1 rotates up and down to perform excavation operations through the bucket teeth 11.

[0036] When the bucket body 1 wears during operation, the pin 21 and the annular pin 22 can be removed to release the restriction on the bucket body 1, and then a new bucket body 1 can be replaced. The upper and lower ends of the bucket body 1 and the connection holes with the connecting rod body 3 and the front digging frame body 4 are aligned, and the two pins 21 are inserted into the aligned connection holes respectively. Then, the annular pin 22 is inserted into the pin hole at one end of the pin 21 to cooperate with the head at the other end of the pin 21 to limit the bucket body 1 from being separated from the connecting rod body 3 / front digging frame body 4, thereby completing the installation of the new bucket body 1.

[0037] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
