Technical Field

[0001] This utility model relates to the technical field of tool changing mechanism, and in particular to a quick tool changing mechanism for a trenching machine. Background Technology

[0002] A trenching machine is a new type of efficient and practical trenching and dredging equipment, mainly used for laying farmland pipelines, urban and rural fiber optic cables, and other projects. Trenching machines are characterized by simple structure and convenient operation. They can not only improve project efficiency but also reduce labor intensity and save resources. The quick-change tool mechanism of the trenching machine is a device that can quickly and easily change the tools on the trenching machine. By quickly changing the tools, the downtime of the trenching machine can be greatly reduced, thereby improving production efficiency.

[0014] (III) Beneficial Effects

[0015] This utility model provides a quick-change tool mechanism for a trenching machine, which has the following advantages:

[0016] 1. The quick-change tool mechanism of this trenching machine, through the setting of the lifting assembly and support plate, allows for easy tool changing for trenching machines at different heights. The disc tool is erected and inserted into four sets of positioning rods. Then, depending on the installation height of the trenching machine, the drive motor is activated, causing the threaded rod to rotate on the support frame. The threaded rod then rotates within the threaded holes on the support plate, causing the support plate to slide and rise within the support frame. When the tool is raised to a suitable height, the hydraulic push rod is activated to push the push plate, which in turn moves the disc tool close to the mounting bearing of the trenching machine for installation. This facilitates tool changing for trenching machines at different heights, improving the applicability of the quick-change tool mechanism.

[0017] 2. The quick-change tool mechanism of this trenching machine, through the setting of buffer components and positioning rods, allows for the following operation: When the operator pushes the support frame, the telescopic rod on the positioning rod presses against the mounting shaft surface on the trenching machine. This causes the telescopic rod to extend and retract within the positioning rod, resulting in the damping hydraulic rod contracting under pressure. The buffer spring deforms under pressure, generating elastic force, thereby achieving a buffering and shock-absorbing effect on the positioning rod. This prevents the positioning rod from colliding with the trenching machine, which could damage the surface of the trenching machine or the positioning rod. Simultaneously, it ensures precise alignment of the tools during installation, improving the safety of the quick-change tool mechanism of the trenching machine. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 4This utility model provides a technical solution: a quick-change tool mechanism for a trenching machine, including a support plate 1. Four sets of hydraulic push rods 2 are sleeved inside the support plate 1. A push plate 3 is fixedly connected to the output end of each hydraulic push rod 2. Four sets of positioning rods 4 are slidably connected to the surface of the push plate 3. A telescopic rod 5 is slidably connected to one end of each positioning rod 4. A buffer assembly 6 is fixedly connected inside the telescopic rod 5. Through the buffer assembly 6 and the positioning rods 4, the positioning rods 4 are buffered and shock-absorbing, preventing them from colliding with the trenching machine and causing damage to the trenching machine or the surface of the positioning rods 4. Simultaneously, it ensures precise alignment of the tools during installation, improving trenching efficiency. To ensure the safety of the quick-change tool mechanism of the trenching machine, a lifting assembly 7 is threadedly connected inside the support plate 1. The lifting assembly 7 and the support plate 1 facilitate tool replacement for trenching machines of different heights, improving the applicability of the quick-change tool mechanism of the trenching machine. The buffer assembly 6 includes a damping hydraulic rod 601 fixedly connected inside the telescopic rod 5, and a buffer spring 602 is sleeved on the surface of the damping hydraulic rod 601. The lifting assembly 7 includes a threaded rod 701 threadedly connected inside the support plate 1, and a drive motor 702 is fixedly connected to the top of the threaded rod 701. A motor housing 703 is sleeved on the surface of the drive motor 702.

[0025] Limiting blocks 8 are fixedly connected to both sides of the support plate 1. A support frame 9 is slidably connected to the surface of the limiting block 8. A sliding groove adapted to the limiting block 8 is opened on the inner side of the support frame 9. The sliding groove facilitates the sliding of the limiting block 8 inside.

[0026] The bottom of the support frame 9 is fixedly connected to the chassis 10, and the top of the chassis 10 is fixedly connected to the rotating sleeve 11. The rotating sleeve 11 facilitates the rotation of the threaded rod 701 inside and limits its position.

[0027] Two sets of handles 12 are fixedly connected to one side of the support frame 9. The surface of the handles 12 is fitted with anti-slip sleeves 13. The anti-slip sleeves 13 increase the friction of the handles 12 and prevent slippage.

[0028] The top of the support frame 9 is provided with a rotating hole that matches the threaded rod 701, and the inside of the support plate 1 is provided with a threaded hole that matches the threaded rod 701. The threaded hole facilitates the rotation of the threaded rod 701 inside, thereby driving the support plate 1 to rise and fall.

[0030] Four sets of casters 16 are fixedly connected to the bottom of the chassis 10. Brake pads are installed inside the casters 16, which facilitates braking of the casters 16.

[0031] In this invention, the working steps of the device are as follows:

[0032] First step: When in use, the personnel push the support frame 9, so that the telescopic rod 5 on the positioning rod 4 presses against the mounting shaft surface on the trencher, and then the telescopic rod 5 extends and retracts inside the positioning rod 4, so that the damping hydraulic rod 601 is compressed under force, and the buffer spring 602 is deformed under force to generate elastic force.

[0033] The second step: When in use, the disc cutter is erected and inserted into the four sets of positioning rods 4. Then, according to the installation height of the trencher, the drive motor 702 is started, so that the drive motor 702 drives the threaded rod 701 to rotate on the support frame 9, and then the threaded rod 701 rotates in the threaded hole on the support plate 1.

[0034] The third step involves the threaded rod 701 driving the support plate 1 to slide and rise within the support frame 9. When the plate is raised to a suitable height, the hydraulic push rod 2 is activated to push the push plate 3, which in turn drives the disc cutter to approach the mounting bearing of the trencher for installation.
