[0002] The statements herein are provided only to complement the background of the present disclosure and are not necessarily prior art.

[0003] As an important mechanical equipment for engineering construction, excavators face increasingly harsh and diverse working conditions as the demand diversifies and becomes more complex. In some specific operating environments, excavators may need to be equipped with pendulum structure accessories. The design of such accessories enables excavators to be more flexible and efficient during excavation operations, especially in situations that require fine operations or work in narrow spaces. Pendulum structure accessories can provide greater operating range and better controllability, thereby improving the accuracy and safety of operations. In some light-load working conditions, in order to improve the working efficiency and adaptability of the excavator, it may be necessary to extend the working length of the accessory. By extending the accessory mounting structure of the dipper arm, the excavator can work at a greater distance, thereby reducing operation time and improving operation efficiency.

[0004] The connection device mentioned in the existing patent publication CN210439351U is directly sleeved on the excavator dipper arm, which results in that the length of the dipper arm after installation is too long to affect the transportation size of the whole machine and cannot offset the working range lost by the accessory due to maintaining the pendulum structure. Content of the utility model

[0005] The purpose of the present disclosure is to provide an excavator accessory extension mounting rod and an excavator, which can at least solve one of the above technical problems.

One end of the extension mounting rod is an accessory mounting portion, and the other end is a dipper arm mounting portion. Pin shaft extension seats are arranged on both sides of the accessory mounting portion and the dipper arm mounting portion. The outer side of the side plate close to the dipper arm mounting portion is also provided with a pin shaft extension seat.

[0007] Further, the width of the side plate itself gradually narrows and bends downward from the dipper arm mounting portion to the accessory mounting portion, and the distance between the two side plates gradually narrows from the dipper arm mounting portion to the accessory mounting portion.

[0008] Further, the hole diameter of the tool mounting portion pin shaft extension seat is consistent with the hole diameter of the pin shaft hole of the tool and the hole diameter of the pin shaft extension seat of the arm mounting portion is consistent with the hole diameter of the pin shaft hole of the arm front end.

[0009] Further, the side plate is outwardly curved near one end of the tool mounting portion to improve the connection strength between the side plate and the upper top plate and the lower bottom plate.

[0010] Further, the distance between the upper top plate and the lower bottom plate gradually decreases with the change of the width of the side plate and is downwardly curved.

[0011] Further, the curved portions of the upper top plate and the lower bottom plate are provided with through holes.

[0012] Further, the upper top plate and the lower bottom plate are provided with grooves near one end of the tool mounting portion to facilitate the swinging of the tool after installation.

[0013] Further, the upper top plate is vertically provided with a pipeline mounting plate for fixing the hydraulic pipeline of the excavator near one end of the arm mounting portion.

[0014] Further, the extension mounting rod is integrally welded into a box type structure.

[0015] Another aspect of the embodiment of the present disclosure provides an excavator, which comprises an arm, a tool and the above-mentioned excavator extension mounting rod, and the extension mounting rod is connected with the arm and the tool through a pin shaft.

[0016] The beneficial effects of one or more of the above technical solutions are:

[0023] As Figures 1-3 shown, the embodiment provides an excavator implement extension mounting rod and an excavator, comprising an extension mounting rod, the extension mounting rod is integrally welded into a box type structure, comprising two side plates 1 arranged in a curved manner and an upper top plate 3 and a lower bottom plate 5 arranged perpendicularly to the two side plates 1, the two side plates 1 and the upper top plate 3 and the lower bottom plate 5 are all integral plate structures.

[0024] Specifically, the two side plates of the extension mounting rod are arranged outwardly curved near one end of the implement mounting portion, through the curved arrangement, the stress can be effectively dispersed, the damage risk of the connecting part caused by excessive load can be reduced, the connecting strength between the side plate and the upper top plate and the lower bottom plate can be improved, and the stability and durability of the whole can also be improved, so that the implement can bear greater load during use, thereby prolonging the service life of the implement.

[0025] As Figure 1 and Figure 2 shown, the width of the two side plates 1 itself gradually narrows and curves downward from the arm mounting portion 6 to the implement mounting portion 7, and the distance between the two side plates 1 gradually narrows from the arm mounting portion 6 to the implement mounting portion 7. By using the integral welding method, after the arm and the extension mounting rod are installed, it will not cause any impact on the use of the whole excavator, but can maintain the controllability of the whole excavator. It is beneficial to maintain the pendulum structure of the implement, thereby ensuring the stability and reliability of the implement during work.

[0026] As Figure 1 shown, one end of the extension mounting rod is the implement mounting portion 7, and the other end is the arm mounting portion 6, pin shaft extension seats 8 are arranged on the two side plates 1 at the positions of the implement mounting portion 7 and the arm mounting portion 6, and the outer side of the side plate 1 close to the arm mounting portion 6 is also provided with a pin shaft extension seat 8.

[0027] Specifically, the pin shaft extension seat 8 has the same hole diameter as the pin shaft hole of the attachment and the pin shaft hole of the front end of the arm, and the pin shaft extension seat 8 can optimize the existing structure without affecting the structural strength. While maintaining the pendulum structure action during the use of the attachment, the working range of the attachment is increased by extending the mounting rod, which offsets the working range lost by the attachment due to the pendulum structure, making it more efficient.

[0028] Meanwhile, the design of the pin shaft extension seat 8 has high flexibility, which can optimize the existing structure without affecting the structural strength. A set of pin shafts can be used for special machines and can be disassembled to add connecting rods and rocker arms as standard excavators, facilitating one machine for multiple purposes and suitable for different models. Without designing new size pin shafts, it can meet the connection between the pin shaft and the attachment and the arm.

[0029] Specifically, when connecting the arm or the attachment, the size and length of the pin shaft used are not fixed. The protruding part of the pin shaft extension seat 8 on the side plate 1 is connected to the arm or the attachment that needs to be connected, and a pin shaft of a uniform size and length can be used to connect the arm or the attachment without designing multiple size and length pin shafts.

[0030] Moreover, by setting the pin shaft extension seat on the side plate, the design of the pin shaft extension seat has high flexibility, which facilitates the disassembly of the extension mounting rod during transportation of the excavator, and thus the transportation size of the entire machine will not be affected by the extension of the arm.

[0031] As shown in Figure 3 The distance between the upper top plate 3 and the lower bottom plate 5 gradually decreases with the change in the width of the side plate 1, and the bending direction is consistent with that of the side plate 1. The bending of the upper top plate 3 and the lower bottom plate 5 enhances the stability of the entire structure. The bending direction of the side plate 1 is consistent with that of the upper top plate 3 and the lower bottom plate 5 adjacent to it, which can better withstand external forces in actual use and improve the durability and safety of the structure.

[0032] As shown in Figure 1 and Figure 2 The bending parts of the upper top plate 3 and the lower bottom plate 5 are provided with through holes 2. One end of the upper top plate 3 and the lower bottom plate 5 close to the attachment mounting part 7 is provided with a recess; the top surface of one end of the upper top plate 3 close to the arm mounting part 6 is vertically provided with a hydraulic pipeline mounting plate 4 for fixing the excavator.

[0033] Specifically, the through holes 2 arranged on the upper top plate 3 and the lower bottom plate 5 are beneficial to prolong welding inside the mounting rod and reduce welding stress, reduce the weight of the sleeve arm on the basis of ensuring the structural strength, save the cost while reducing the load on the front end of the arm, and the grooves arranged on the front end of the upper top plate 3 and the lower bottom plate 5 can be used for the installation of the tool, and the difficulties that may be encountered in the installation process are reduced. The pipeline mounting plate designed on the upper top plate 3 makes the pipe arrangement work more simple, the layout of the pipeline can be more neat and orderly, and thus the cleanliness of the whole machine is improved.

[0034] The utility model further provides a kind of excavator, it includes arm, tool and the excavator extension mounting rod described above, the extension mounting rod is connected between arm and tool by pin shaft.

[0035] The working principle of the utility model is as follows: the pin shaft extension seat 8 can be adjusted according to the specific needs of different models, without replacing other size pin shaft, a set of pin shaft can be used for special machine also can be disassembled sleeve arm and install connecting rod and rocker as standard excavator, it is convenient to realize one machine multiuse, applicable to different models;Without designing new size pin shaft, it can meet the connection between pin shaft, tool and arm;And it does not affect the overall structural strength of extension mounting rod, then the pipeline extended by excavator arm is fixed by pipeline mounting plate 4, improves the cleanliness of the whole machine.

[0036] Although the specific embodiments of the present disclosure are described above in combination with the drawings, it is not a limitation on the protection scope of the present disclosure, and those skilled in the art should understand that various modifications or changes made on the basis of the technical solutions of the present disclosure without creative labor are still within the protection scope of the present disclosure.
