Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Refer to Figures 1 to 4 , a trench digging device for landscaping construction, including a frame 1, a mounting bracket 2 is fixed in the middle of the frame 1, a support 3 is fixed on the top of the mounting bracket 2, a screw 4 is slidably connected inside the support 3, a connecting frame 5 is installed at the bottom of the screw 4, a rotating shaft 6 is rotatably connected in the middle of the connecting frame 5, a trench digging knife 7 is fixedly sleeved outside the rotating shaft 6, a rotating rod 8 is rotatably connected in the middle of the frame 1, rear wheels 9 are fixedly sleeved on both sides of the rotating rod 8, and a front wheel 10 is rotatably connected at the front end of the frame 1. It should be noted that a handle is installed on the side of the frame 1, and an anti-wear sleeve is sleeved outside the handle. Through the handle, it is convenient for the staff to hold and control the traveling direction of the trench digging device. At the same time, the anti-wear sleeve can prevent wear.

[0022] A support block 41 is fixed on the top of the mounting bracket 2, a worm 42 is rotatably connected in the middle of the support block 41, a rocker 43 is fixed at the end side of the worm 42, a worm gear 44 is rotatably connected on the top of the support 3, the worm gear 44 meshes with the worm 42, an external thread is provided on the inner wall of the worm gear 44, and the external thread is in threaded cooperation with the screw 4. It should be noted that an external thread in threaded cooperation with the screw 4 is installed inside the worm gear 44, so that the worm gear 44 can drive the screw to lift stably during rotation.

[0023] A mounting seat 61 is fixed on the side of the frame 1, a motor 62 is fixed in the middle of the mounting seat 61, a transmission rod 63 is fixedly connected to the output end of the motor 62, a first pulley 64 is fixedly sleeved outside the transmission rod 63, a third pulley 81 is coaxially sleeved outside the rotating rod 8, a second pulley 65 is fixedly sleeved at the end side of the rotating shaft 6, and a tension belt 66 is wound and connected outside the first pulley 64, the second pulley 65 and the third pulley 81. It should be noted that the tension belt 66 has elastic stretchability. When the height of the rotating shaft 6 is adjusted, the tension belt 66 can use its own elasticity to always fit outside the three pulleys and then complete its transmission.

[0024] On both sides of the frame 1, there are rotatably connected rotating shafts 1001. An external fixed sleeve of the rotating shaft 1001 is provided with a first pulley 1002. The rotating shaft 1001 is fixedly connected to the front wheel 10. Both ends of the rotating rod 8 are sleeved with second pulleys 1003. The external of the first pulley 1002 and the second pulley 1003 are wound and connected with a transmission belt 1004.

[0025] In the present utility model, when using the device for trenching, first, adjust the trenching knife 7 according to the required trenching depth. Manually rotate the rocker 43 to drive the worm 42 to rotate and engage with the worm gear 44. The worm gear 44 rotates under force, and its internal external thread then cooperates with the thread to drive the screw rod 4 to lift and lower. The trenching knife 7 installed at its bottom through the connecting frame 5 also lifts and lowers accordingly, thereby realizing the adjustment of the trenching depth of the trenching knife 7 and improving the flexibility of use.

[0026] Subsequently, start the motor 62 to drive the first pulley 64 to rotate and drive the rotating shaft 6 in the middle of the second pulley 65 to rotate in the connecting frame 5 through the tensioning belt 66. The trenching knife 7 on its external rotates accordingly to complete the trenching operation. At the same time, during the transmission of the tensioning belt 66, the third pulley 81 rotates synchronously. The rotating rod 8 in the middle of the third pulley 81 then drives the rear wheels 9 at its both ends to rotate. At the same time, the external of the first pulley 1002 on the external of the rotating rod 8 also rotates synchronously and drives the second pulley 1003 to rotate through the transmission belt 1004. The rotating shaft 1001 in the middle of it then rotates on the side wall of the bracket to drive the front wheel 10 to rotate, enabling the device to realize rapid mobile trenching. When the driving road condition is poor, it only requires the staff to hold the handrail and follow the device to move, without the staff having to push the device forcefully, saving the labor of the staff.

[0027] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
