Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a novel excavator. Background Art

[0002] An excavator, also known as an excavating machine or a backhoe, is an earth-moving machine that uses a bucket to dig materials above or below the surface and load them into transport vehicles or unload them to a stockpile.

[0003] The application number in the existing public technology is: CN202120969025.8. A new type of excavator is equipped with a rotating device, which can enable the boom to rotate 360 ​​degrees, thereby expanding the working area. In addition, a heat dissipation device is provided. Two fans are provided in the heat dissipation device, one is a high-pressure fan, and the other is a large-volume fan. The pressure fan can blow through the radiator, which has a better heat dissipation effect on the hydraulic oil on the one hand, and on the other hand, it can allow the wind to penetrate the radiator to reach the explosion-proof motor, and at the same time dissipate heat for the hydraulic system and the explosion-proof motor. The air volume fan draws air outward to make the engine compartment in a negative pressure state, the air duct is more reasonable, and the heat dissipation effect is better.

[0004] However, there are still some problems in the use of existing excavators: buckets are common accessories of excavators. Excavators use buckets for earthwork excavation and loading operations. During the operation process, especially when used in rock loading conditions, it is inevitable to be impacted and worn by stones during the operation process. In order to extend the service life of the excavator bucket, the bucket under harsh working conditions will add anti-wear structures to the bottom and sides of the bucket. The traditional bucket anti-wear structure is welded by multiple plates, and many of its welds are prone to cracking and wear due to direct contact and collision with materials, resulting in low reliability of the anti-wear structure; at the same time, the position and size of the anti-wear are relatively random and diverse, involving many specifications of the plates and low versatility; the amount of cutting and welding is large, and the production cost is relatively high; in addition, the anti-wear plates are welded one by one, and they cannot be disassembled and replaced, resulting in high maintenance convenience and cost in the later stage. In addition, when the excavator is operating, a large amount of dust is easily generated due to excavation and friction. If it is not handled, it is easy to have a certain impact on the health of personnel and cause environmental pollution, and the use effect is not very good.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0030] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0031] According to an embodiment of the utility model, a new excavator is provided.

[0032] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-5 As shown, a new excavator according to an embodiment of the utility model comprises an excavator body 1 and a bucket 2. The bucket 2 is connected to one end of the arm of the excavator body 1. The bucket 2 is composed of a connecting side plate 7 and a center plate 11. The connecting side plates 7 are provided with two groups, and the center plates 11 are provided with multiple groups. The connecting side plates 7 and the center plates 11 are provided with connecting grooves 9 on their surfaces. The friction plates 10 are threadedly connected to the inside of the connecting grooves 9 through fixing screws 14. The connecting side plates 7 and the center plates 11 are both recessed structures. Snap-in plates 13 are symmetrically provided at the middle positions of the surfaces of both ends of the center plate 11. A groove for installing the snap-in plate 13 is provided at the middle position of the surface of the connecting side plate 7. The connecting side plate 7 and the center plate 11 are threadedly connected by fixing screws 14. Positioning holes 8 for connection are provided on the external surfaces of the connecting side plates 7, the center plates 11 and the friction plates 10. A connecting head 12 for connecting the machine arm is provided at the top surface of the connecting side plate 7.

[0033] In one embodiment, a liquid storage barrel 3 is fixedly installed at one side of the bottom end of the excavator body 1, and a water pump 4 is provided inside the liquid storage barrel 3. One end of the water pump 4 passes through one side of the liquid storage barrel 3 and is connected to a spray plate 5 located at the bottom end of the outer peripheral surface of the excavator body 1 through a pipeline. A plurality of groups of atomizing nozzles 6 are evenly installed around the surface of the spray plate 5. The spray plate 5 is arranged around the surface of the excavator body 1, thereby expanding the subsequent dust reduction range and improving the dust reduction effect.

[0034] In one embodiment, the spray plate 5 is an inverted trapezoidal structure, which enables the spray plate 5 to spray the front, bottom and rear of the excavator body 1 at the same time when the excavator body 1 is in operation, so as to achieve dust reduction.

[0035] In one embodiment, the friction plate 10 is made of metal material, and the friction plate 10 can come into contact with the excavated material before the bucket 2, thereby reducing the friction effect on the bucket 2, avoiding excessive wear thereof, and extending its service life.

[0036] In one embodiment, the fixing screw 14 is located inside the positioning hole 8 and is lower than the depth of the positioning hole 8. After installation, the fixing screw 14 is inside the positioning hole 8, and its location inside the positioning hole 8 can prevent external substances from causing friction to the fixing screw 14 when the excavator body 1 is running, causing the fixing screw 14 to move, thereby causing a decrease in stability.

[0037] In one embodiment, a solenoid valve is installed on the pipe at one end of the liquid storage barrel 3, and the solenoid valve is electrically connected to the controller inside the excavator body 1. The solenoid valve and the controller are common equipment with mature application technology, so they will not be described in detail.

[0038] In one embodiment, docking plates are symmetrically provided on both sides of the surface of the center plates 11 of one group, and docking plates are provided on only one side of the surface of the center plates 11 at other positions, and a groove for installation is provided on the other side. The position setting of the docking plates on the surface of the center plates 11 is to ensure that the center plates 11 can be connected to each other and to the connecting side plates 7, thereby ensuring that the bucket 2 can be smoothly constructed.

[0039] In one embodiment, the size of the snap-in plate 13 is the same as the size of the corresponding groove. The size settings of the snap-in plate 13 and the groove are to ensure that the snap-in plate 13 can be smoothly inserted into the groove for docking, and to facilitate the subsequent tightening operation of the fixing screw 14 to ensure the connection stability of the structure.

[0040] Working principle: When the device is in use, the personnel can connect the center plate 11 with the connecting side plates 7 at both ends through the fixing screws 14, and then the personnel can connect the constructed bucket 2 with the arm of the excavator through the connecting head 12, which is convenient for subsequent excavation operations. At the same time, the personnel can also install the friction plate 10 inside the connecting groove 9 on the surface of the connecting side plate 7 and the center plate 11, so as to enhance the overall anti-friction property of the device, so that the shoveled material contacts the friction plate 10 before the bucket 2, avoiding excessive wear on the bucket 2 body, ensuring its overall service life, and after the bucket 2 has been in operation for a long time, the surface of the bucket 2 will be free of friction. When worn and damaged, personnel only need to disassemble and replace the damaged parts, and there is no need to replace the entire part. Compared with the traditional welded one-piece structure, it can improve the overall maintenance convenience while ensuring strength and reduce the cost of maintenance. When the device is excavating, the liquid stored in the liquid storage barrel 3 can be discharged through the water pump 4, and diffused to the surroundings through the atomizing nozzle 6, so that the diffused atomized water can absorb and settle the dust generated during excavation, reduce pollution to the environment, and ensure the respiratory health of the operator. The device as a whole has the advantages of convenient replacement of the bucket 2, long service life, and dust reduction during operation.
