[0037] like Figures 1 to 10 As shown, the present invention proposes a quick-connect excavation bucket and a matching part, including a bucket body 1 and a fixing device 2 installed on the bucket body 1. When the bucket body 1 is installed, the fixing device 2 is connected to the matching part installed on the excavator, and a protruding portion 1 is provided on the upper part of the fixing device 2, and the protruding portion 1 is abutted against the matching part.

[0038] Based on the above content, the present invention also proposes a matching piece for a quick-connect excavation bucket, which is applied to the quick-connect excavation bucket, including a matching piece body 3, the matching piece body 3 including a fixed arm 31 and an insertion component 32, the insertion component 32 is installed on the excavator through the fixed arm 31, and the side of the fixing device 2 is provided with a positioning groove 1 21, a positioning groove 22 and a positioning groove 3 23, when the bucket body 1 is installed, the insertion component 32 is inserted into the positioning groove 3 23, the positioning groove 1 21, and the positioning groove 2 22 in sequence to form a fixation, and the protrusion 1 of the fixing device 2 is against the surface of the fixing arm 31; an inwardly concave groove is provided at a place near the protrusion of the fixing device 2 at the upper end of the fixing arm 31, and the groove is an arc surface, and the arc surface gradually deepens from bottom to top;

[0039] The fixed arm 31 serves as the core supporting structure of the fitting body 3. Its design fully considers the stability and convenience of bucket installation. The fixed arm not only undertakes the task of firmly installing the insertion assembly 32 on the excavator, but also forms a precise match with the raised part of the fixing device 2 on the bucket body 1 through its special surface design - an arc-shaped groove that gradually deepens from bottom to top. This design not only enhances the stability of the bucket during operation, but also greatly simplifies the installation process of the bucket, so that the operator can quickly install and fix the bucket without tedious manual alignment.

[0040] The insertion component 32 is another key component in the quick-connect excavation bucket fitting of the present invention. It forms an ingenious matching mechanism with the positioning grooves one, two, and three on the fixing device 2. The insertion component is designed to be inserted one by one in a specific order. This design not only ensures the precise alignment between the bucket body and the fitting body, but also greatly reduces the error and difficulty in the installation process through a step-by-step guidance method. At the same time, the shape and size of the positioning groove and the insertion component are precisely matched to prevent misalignment or jamming during the insertion process, thereby ensuring the quick and accurate installation of the bucket.

[0041] Furthermore, the insertion component 32 includes a mounting plate 324 and a movable abutment member 321, a connecting arm 322 and a motor 323 mounted on the mounting plate 324. The mounting plate 324 is connected to the connecting arm 322 via a rotating bearing 3241. The movable abutment member 321 is respectively connected to the mounting plate 324 and the connecting arm 322. A screw rod 3231 is mounted on the output shaft of the motor 323. The screw rod 3231 is embedded in the positioning groove three 23 and forms a threaded connection with the positioning groove three 23. The output shaft of the movable abutment member 321 is inserted into the positioning groove one 21. A fixed head 3221 is mounted on the output shaft of the connecting arm 322. The fixed head 3221 is inserted into the positioning groove two 22 and embedded in the card slot 221 set in the positioning groove two 22.

[0042] Moreover, the port of the positioning groove three 23 is set in an open shape, and a limit plate abutment block 3232 is symmetrically set on one side of the motor 323 close to the screw rod 3231, and the two limit plate abutment blocks 3232 are set in an eight-shaped structure. When the screw rod 3231 is inserted into the positioning groove three 23, the limit plate abutment block 3232 abuts against the surface of the positioning groove three 23. The positioning groove three 23 and the motor 323 are both inclined. The screw rod 3231 is inserted into the positioning groove three 23 to form a fixation. The positioning groove three 23 is provided with a chip removal hole 24 near the port, and the chip removal hole 24 extends downward to the surface of the fixing device 2;

[0043] The motor 323 is used as a driving component, and a screw rod 3231 is installed on its output shaft. The screw rod 3231 is designed to be embedded in the positioning groove three 23 and form a threaded connection with the positioning groove three. This design enables the screw rod 3231 to rotate and move along the thread track of the positioning groove three 23 when the motor 323 is started, thereby realizing automatic locking of the insertion component and the fixing device. In the design of the positioning groove three 23, its port is set in an open shape to facilitate the insertion of the screw rod 3231. At the same time, in order to increase the stability of the screw rod during the insertion process, the motor 323 is symmetrically provided on one side close to the screw rod. A limit plate abutment block 3232 is provided, and the two limit plate abutment blocks are arranged in an eight-shaped structure. When the screw rod is inserted into the positioning groove three, the limit plate abutment block abuts against the surface of the positioning groove three, effectively preventing the screw rod from shaking and misaligning. In addition, the positioning groove three 23 and the motor 323 are both inclined. This design not only facilitates the inclined insertion of the screw rod, but also enables the screw rod to generate a greater locking force during the rotation process, thereby improving the stability of the installation. A chip removal hole 24 is also provided near the port of the positioning groove three, and the chip removal hole extends downward to the surface of the fixing device 2, which is used to discharge impurities and keep the positioning groove clean and unobstructed.

[0044] During the installation process, the operator only needs to use the excavator to move the matching part 3 close to the fixing device 2, insert the screw rod 3231 into the positioning groove three 23 first, and start the motor 323 to rotate the screw rod. Since a threaded connection is formed between the screw rod and the positioning groove three, the screw rod will automatically move along the thread track of the positioning groove three during the rotation process, and gradually lock in the positioning groove three. At the same time, the output shaft of the movable abutment member 321 will be inserted into the positioning groove one 21, and the fixed head 3221 installed on the output shaft of the connecting arm 322 will be inserted into the positioning groove two 22 and embedded with the card slot 221 set in the positioning groove two. In this way, through the motor drive, screw rod transmission and the precise coordination between the various components, the bucket body 1 and the matching part body 3 can be quickly and accurately installed without the need for manual cumbersome alignment and adjustment operations.

[0045] Furthermore, the movable abutment member 321 includes a cylinder 1 3211, a cylinder 2 3212, a connecting rod 3213 and a fixing rod 3214, the two ends of the connecting rod 3213 are respectively connected to the cylinder 1 3211 and the fixing rod 3214 through a rotating shaft, and the two ends of the cylinder 2 3212 are respectively connected to the cylinder 1 3211 and the side of the connecting arm 322, so that the cylinder 1 3211 can swing toward the fixing device 2 by driving the output shaft of the cylinder 2 3212 to extend and retract; the side of the cylinder 1 3211 is provided with an adsorption magnetic plate 2113 for adsorbing it on the surface of the fixing device 2, and when the cylinder 1 3211 is adsorbed to the surface of the fixing device 2 by the adsorption magnetic plate 2113, the cylinder 1 3211 is aligned with the positioning groove 1 21;

[0046] Furthermore, the cylinder 1 3211 comprises a telescopic tube 2111 and a sleeve 2112, the sleeve 2112 is sleeved outside the telescopic tube 2111, a half tube 101 is arranged at the lower end of the telescopic tube 2111, a half tube 2 102 corresponding to the half tube 101 is arranged in the sleeve 2112, a spring 2114 is arranged in the half tube 101, and the upper and lower ends of the spring 2114 are respectively connected to the telescopic tube 2111 and the sleeve 2112;

[0047] An air cavity 100 is provided between the sleeve 2112 and the half pipe 101, and an air hole 103 for connecting the air cavity 100 is provided on the surface of the sleeve 2112, so that the air pressure in the air cavity 100 can be controlled by connecting the air hole 103 to an air compressor to adjust the length of the telescopic tube 2111 extending outward;

[0048] In the design of the matching parts of the quick-connect excavation bucket, the automatic fixing process of the movable abutment component 321 and the connecting arm 322 integrates the principles of air pressure control and mechanical locking to ensure a stable connection between the bucket body and the matching part body. First, the cylinder 1 3211 in the movable abutment component 321 is firmly adsorbed on the surface of the fixing device 2 through the adsorption magnetic plate 2113 on its side, and the position of the cylinder 1 is aligned with the positioning groove 1 21. At this time, the telescopic abutment tube 2111 inside the cylinder 1 maintains a certain initial length under the action of the spring 2114. Then, the cylinder 2 3212 starts to work, and its output shaft is telescopic to drive the cylinder 1 to swing toward the fixing device. As the cylinder 1 swings, the telescopic abutment tube gradually extends outward under the elastic force of the spring until its lower end is in close contact with the inner wall of the positioning groove 1. In order to further enhance the stability of the cylinder 1 The connection stability between the cylinder and the positioning groove one is achieved by adjusting the air pressure of the air chamber 100 inside the cylinder one by an external air compressor. As the air pressure increases, the telescopic tube is subjected to greater pressure, so that it fits more closely to the inner wall of the positioning groove one, thereby achieving a stable connection between the cylinder one and the positioning groove one. At the same time, the fixed head 3221 on the output shaft of the connecting arm 322 begins to move toward the positioning groove two 22. Since the cylinder one has been firmly connected to the positioning groove one, the output shaft of the fixed arm can maintain a stable trajectory during the movement. As the fixed head gradually approaches, it is finally accurately inserted into the positioning groove two and fits with the card slot 221. Once the fixed head and the card slot are fitted, the fixed arm is firmly locked in the positioning groove two. At this time, the bucket body and the matching part body are automatically fixed without the need for additional manual operation or adjustment.

[0049] Among them, in the design of the matching parts of the quick-connect excavation bucket, the telescopic abutment tube 2111 is a key component of the movable abutment member 321. It realizes a stable connection between the bucket body and the matching part body by closely matching with the positioning groove 21. At the same time, the addition of the spring 2114 adds a layer of soft connection characteristics to this connection. When the adsorption magnetic plate 2113 is adsorbed to the surface of the fixing device 2, the cylinder 3211 and the telescopic abutment tube 2111 inside it are also firmly positioned on the fixing device. At this time, the lower end of the telescopic abutment tube is aligned with the opening of the positioning groove 21, which is ready for the next insertion action. 1, or through the adjustment of air pressure, the telescopic tube 2111 begins to gradually extend downward until its lower end is completely inserted into the positioning groove 21. Since the lower end of the telescopic tube is designed to be closely matched with the inner wall of the positioning groove, once inserted into place, a stable mechanical connection can be formed. In the process of inserting the telescopic tube 2111 into the positioning groove 21, the spring 2114 plays a vital role. One end of the spring is connected to the telescopic tube, and the other end is connected to the internal structure of the cylinder 3211. When the telescopic tube is subjected to external force such as resistance when inserted into the positioning groove, the spring can be elastically deformed, thereby absorbing and buffering this part of the external force.

[0050] This soft connection feature not only helps to protect the telescopic abutment and the positioning groove from damage, but also improves the flexibility and adaptability of the connection. Even when the external environment or working conditions change, such as temperature changes causing material expansion and contraction, the spring can maintain the stability and reliability of the connection through its elastic deformation. Once the telescopic abutment 2111 is fully inserted into the positioning groove 21 and a soft connection is formed through the spring 2114, the entire movable abutment member 321 is firmly locked on the fixing device 2. At this time, a stable connection is achieved between the bucket body and the mating part body. In addition, due to the elastic effect of the spring, even when the external environment or working conditions change, the telescopic abutment can automatically adjust its position or shape to maintain a close fit and a stable connection with the positioning groove.

[0051] In addition, the fixed head 3221 has an air cavity 201 extending to the left and right ends, and the surfaces of the cylinder 1 3211 and the two ends of the air cavity 201 are respectively provided with outwardly protruding protrusions 202, and the two protruding parts 202 are each provided with a solid plug rod 203, the solid plug rod 203 protrudes from the surface of the protruding part 202, and the solid plug rod 203 is provided with a step edge protruding outward on one side close to the middle of the air cavity 201, and the air cavity 201 is provided with a sliding groove at the corresponding position of the step edge, and the step edge on the surface of the solid plug rod 203 is slidably arranged in the sliding groove, and the air cavity 201 extends outward through an air hole 204, and is connected to an external air compressor through the air hole 204 to generate positive and negative pressure to control the extension and contraction of the solid plug rod 203, and when the solid plug rod 203 extends outward, it is embedded in the card groove 221 on the inner side of the positioning groove 22;

[0052] During the fixing process, when the cylinder 1 3211 is adsorbed to the surface of the fixing device 2 through the adsorption magnetic plate 2113 and aligned with the positioning groove 1 21, the output shaft of the connecting arm 322 starts to move, so that the fixing head 3221 approaches the positioning groove 22. At this time, the air pressure in the air chamber 201 is controlled by the air compressor to make the solid plug rod 203 extend outward. As the solid plug rod extends, its step slides along the slide groove until it is finally embedded in the card groove 221 on the inner side of the positioning groove 2. Once the solid plug rod is completely embedded in the card groove, the fixing head is firmly locked. It is fixed on the positioning groove 2, thereby realizing a stable connection between the bucket body and the matching part body. This linkage fixing mechanism not only simplifies the installation process and improves the installation efficiency, but also ensures the accuracy and reliability of the connection. In summary, the linkage fixing mechanism between the fixed head 3221 and the cylinder 1 3211 realizes a stable connection between the bucket body and the matching part body through the principles of air pressure control and mechanical locking. The design of this mechanism not only improves the installation efficiency and accuracy of the bucket, but also provides a strong guarantee for the smoothness and safety of the construction process.

[0053] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
