[0002] In the fields of engineering construction and material handling, various types of engineering machinery, such as excavators and loaders, are widely used in mining, construction, earthwork and other scenarios. The operating efficiency and adaptability of these machines directly affect the project progress and operating costs.

[0003] Specifically, regarding the working device of construction machinery, the existing connection structure between the bucket and the boom mostly uses traditional bolt fastening. This requires repeated tightening of the bolts during assembly and disassembly, which is not only cumbersome and time-consuming, but also has limited effectiveness in preventing loosening. Over time, bolts are prone to loosening or even falling off, affecting the stability of equipment operation. Furthermore, the existing boom length adjustment is mostly a single telescopic structure, which is difficult to flexibly adjust to the appropriate length when facing different working depths and material accumulation heights. This results in low operating efficiency under complex conditions and an inability to meet diverse construction needs. Utility Model Content

When installation is required, the bucket arm is...

[0027] The fixing bolt 2 at the top of the bucket 1 is aligned with the stick branch 3. The bolt pin 5 is passed through the corresponding holes on the fixing bolt 2 and the stick branch 3. The bolt cap 6 at the bottom of the bolt pin 5 is fixed. Then, the sleeve 8 is put on the top of the bolt pin 5, and the fixing pin 7 is inserted through the cotter pin hole 9 to complete the fixed connection between the bucket 1 and the stick branch 3. The stick body 4 is sleeved on the outside of the hydraulic rod 13.

[0028] Bolt pin 5 has a boom branch 3 fitted at its middle end. A slide rail 21 is fixedly connected to the bottom of boom branch 3, and a slider 20 is slidably connected to the bottom of slide rail 21. A base 15 is fixedly connected to the bottom of slider 20. A slider 17 is fixedly connected to the right side of boom branch 3. Two gears 18 are mounted on the top side of base 15, and a motor 19 is fixedly connected to the top side of base 15. The drive end of motor 19 is connected to one of the gears 18. A belt 16 is mounted on the outside of gear 18, and the outside of belt 16 is connected to slider 17. When motor 19 starts, its drive end drives the two gears 18 to rotate. The belt 16 on the outside of gear 18 is driven when gear 18 rotates, forming a circular transmission. The outside of belt 16 is fixedly connected to slider 17, causing slider 17 to move back and forth along the right side of boom branch 3. When slider 17 moves under belt 16, the fixed connection between base 15 and slider 20 drives slider 20. The stick branch 3 slides synchronously on the slide rail 21, allowing it to be adjusted forward and backward to meet the position adjustment requirements under specific working conditions.

[0029] Refer to Figure 1 and Figure 4 This utility model provides an embodiment of a quick-release stick, wherein a rack is provided on the inner wall of the belt 16, a base 10 is provided on the bottom side of the base 15, a slider 11 is provided on the top of the base 10, a groove is provided on the bottom side of the base 15, the slider 11 is slidably connected in the groove, a hydraulic rod 13 is provided on the top of the base 10, a guide rail 14 is fixedly connected to the left side of the base 15, the driving end of the hydraulic rod 13 is connected to the guide rail 14, a fixing port 12 is sleeved on the hydraulic rod 13, and the stick body 4 is fixedly connected to the bottom end of the base 10. When the device is working, the base 10 is slidably connected to the groove of the base 15 through the slider 11. When the hydraulic rod 13 extends or retracts, it can push the guide rail 14 to drive the base 15 to slide back and forth, and at the same time, the sliding adjustment of the stick branch 3 plays a driving role. The base 10 has a fixed connection to a fixing port 12 at its top. The fixing port 12 is fitted onto the hydraulic rod 13 for positioning. The stick branch 3 has a pin hole for fitting.

[0030] On the bolt pin 5, a cross-shaped groove is provided at the top of the cotter pin hole 9, and a straight groove is provided at the bottom of the fixing pin 7. The design of the cross-shaped groove of the cotter pin hole 9 and the straight groove of the fixing pin 7 facilitates quick fixing and separation by pinning in different directions during assembly and disassembly.

[0031] Working principle: When quick disassembly is required using this device, first align the fixing bolt 2 at the top of the bucket 1 with the hole of the stick branch 3. Pass the bolt pin 5 through the corresponding hole of the fixing bolt 2 and the stick branch 3, and fix the bottom end with the bolt cap 6 to ensure initial positioning. Place the sleeve 8 on the top of the bolt pin 5, and insert it into the fixing pin port 7 through the cotter pin hole 9. Utilize the misalignment and engagement of the cross-shaped groove of the cotter pin hole 9 and the straight groove of the fixing pin port 7 to rotate the pin connection direction for quick fixing. Reverse operation: pull out the cotter pin, rotate the fixing pin port 7 to align the groove direction, and quickly remove the sleeve 8 and bolt pin 5, separating the bucket 1 from the stick branch 3. After the motor 19 starts, its drive end drives the two gears 18 to rotate. The belt 16 on the outside of the gears 18 is driven when the gears 18 rotate, forming a ring transmission. The outside of the belt 16 is fixedly connected to the slider 17, causing the slider 17 to move back and forth along the right side of the stick branch 3. When the slider 17... When moving under the belt 16, the fixed connection between the base 15 and the slider 20 will cause the slider 20 to slide synchronously on the slide rail 21, so that the stick branch 3 can be adjusted back and forth. The base 10 is slidably connected to the base 15 through the slide groove of the slider 11. The driving end of the hydraulic rod 13 is connected to the guide rail 14. When the hydraulic rod 13 extends or retracts, it pushes the guide rail 14 to drive the base 15 to slide back and forth, so that the stick branch 3 moves synchronously with the base 15, realizing the extension and retraction adjustment in the overall back and forth direction, thereby meeting the use of different working conditions. The fixing port 12 is sleeved on the hydraulic rod 13, which plays the role of positioning and stabilizing the hydraulic rod 13.
