[0019] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0020] Reference Figure 1-4 The embodiment of the present invention is a protective structure for the blade plate of an excavator bucket, which includes: a bucket body 1, an isolation cover 2 is provided at the lower end of the bucket body 1, and the isolation cover 2 completely covers the position where the blade is installed at the lower end of the bucket body 1, and the isolation cover 2 prevents the blade plate part of the bucket body 1 from being exposed to the outside, and transfers the wear of the blade plate to the surface of the isolation cover 2. By maintaining and replacing the isolation cover 2, the cost of maintaining the bucket body 1 itself is reduced. The upper surface of the isolation cover 2 is provided with two limiting grooves 3, which are relatively distributed on the left and right. The two limiting grooves 3 pass through the left and right surfaces of the isolation cover 2 respectively, and the two limiting grooves 3 do not pass through each other. The limiting grooves 3 are convenient for adding auxiliary components to fix the isolation cover 2, and provide basic conditions for fixing the isolation cover 2.

[0021] The inner wall of the limiting groove 3 is provided with a reinforcing plate 4, and one end of the reinforcing plate 4 close to the inner wall of the bucket body 1 passes through the bucket body 1, and the end of the reinforcing plate 4 away from the inner wall of the bucket body 1 is clamped with the isolation cover 2. The reinforcing plate 4 is composed of a connecting plate 8, a positioning plate 9, an upper cover plate 10, and a clamping plate 11. The clamping plate 11 passes through the interior of the isolation cover 2. The reinforcing plate 4 uses a complex socket structure to integrate the reinforcing plate 4 with the isolation cover 2 to improve the stability of the isolation cover 2 when it is in action. The above device cooperates with the isolation cover 2 to form a protective mechanism. The upper part of the reinforcing plate 4 A section 7 is provided on the surface, and the section 7 is in an inclined state, and the height of the lowest part of the section 7 is in the same plane as the upper surface of the isolation cover 2. The inclined section 7 reduces the blocking point of the reinforcement plate 4 and reduces the accumulation of soil and impurities at the reinforcement plate 4. In the process of setting the section 7, the section 7 can be changed to a more suitable structure according to the force data of the bucket during use. At the same time, the same section 7 can be set on the surface of the isolation cover 2 according to the situation, so as to reduce the resistance points of the isolation cover 2 and the reinforcement plate 4 during use.

[0022] The lower surface of the isolation cover 2, the end of the reinforcement plate 4 away from the inner wall of the bucket body 1, and the surface of the bucket body 1 are all provided with reinforcement screw holes 12. The reinforcement screw holes 12 do not pass through the bucket body 1. The reinforcement screw holes 12 are the basic conditions for using external objects to fix the protection mechanism. The left and right surfaces of the bucket body 1 are both provided with a receiving cavity 5, and the positioning plate 9 is located inside the receiving cavity 5. The positioning plate 9 and the isolation cover 2 are provided with a receiving groove 6 at the position where the reinforcement screw hole 12 is set. The diameter of the receiving groove 6 is larger than the diameter of the reinforcement screw hole 12. The receiving cavity 5 and the receiving groove 6 improve the flatness of the bucket surface. The size relationship between the receiving groove 6 and the reinforcement screw hole 12 makes it convenient for the staff to clean the soil and impurities accumulated inside the receiving groove 6, and improves the convenience of disassembling and assembling the reinforcement bolts. The interior of the receiving groove 6 is fixedly connected with a sealing ring 13. The surface of the sealing ring 13 is in close contact with the surface of the bolt. The sealing ring 13 improves the sealing effect when the reinforcement screw hole 12 is in action, and reduces the influence of vibration on the stability of the reinforcement bolt.

[0023] Working principle: The isolation cover 2 can be set as a prefabricated part, wherein in the process of producing the isolation cover 2, the surface of the isolation cover 2 can also be provided with a cut surface 7 according to work requirements, and the structure of the cut surface 7 can be improved according to the stress conditions, so as to further reduce the resistance points of the isolation cover 2 and the reinforcement plate 4. When installing the protection mechanism, first compare the isolation cover 2 with the bucket body 1, and then push the isolation cover 2 to snap the isolation cover 2 and the bucket body 1 together, and then push the reinforcement plates 4 on the left and right sides through the penetration of the bucket body 1 into the interior of the bucket body 1 and snap them together with the isolation cover 2. When the upper cover plates 10 of the two reinforcement plates 4 are in close contact, the snap-on plates 11 of the reinforcement plates 4 are in When the isolation cover 2 is completely entered, the isolation cover 2 and the reinforcement plate 4 are finally fixed by the reinforcement bolts through the reinforcement screw holes 12. At this time, the isolation cover 2 is restricted by the reinforcement bolts and the reinforcement plate 4 to ensure that the isolation cover 2 has sufficient stability when the excavator is working. In the process of installing the isolation cover 2, in order to reduce the wear effect between the isolation cover 2 and the bucket body 1, a rubber pad of appropriate thickness can be added to the inner wall of the isolation cover 2 to reduce the wear effect between the isolation cover 2 and the bucket body 1. At the same time, the isolation cover 2 with the rubber pad added can reduce the penetration of water vapor into the interior of the isolation cover 2, which can further improve the protection effect of the isolation cover 2 on the blade plate of the bucket body 1.

[0024] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
