[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] See also Figure 1-Figure 6 , the present invention provides a technical solution: A combined operation device for landscaping engineering, comprising a support frame 1, a lifting mechanism 2 is provided on the support frame 1, a first rack 5 is fixedly connected to the support frame 1, a vibration mechanism 6 is installed on the lifting mechanism 2, the vibration mechanism 6 and the first rack 5 are movably engaged, an adjustment mechanism 17 is provided on the vibration mechanism 6, an alternating mechanism 21 is provided on the adjustment mechanism 17, a driving mechanism 29 is provided on the adjustment mechanism 17, the driving mechanism 29 is movably connected to the adjustment mechanism 17 and the alternating mechanism 21 respectively, and a material grabbing assembly 36 and a pit digging assembly 37 are provided on the alternating mechanism 21; When working, the equipment is moved to a suitable position. The front side of the support frame 1 is U-shaped, so the support frame 1 can be pushed to the plant that needs to be transplanted, so that the plant is located on the inner side of the support frame 1, and then the driving mechanism 29 is controlled to drive the adjustment mechanism 17 to work. When the adjustment mechanism 17 is working, the adjustment mechanism 17 adjusts the position of the alternating mechanism 21 so that the grabbing assembly 36 on the alternating mechanism 21 is located on the upper side of the plant. At the same time, the grabbing assembly 36 is controlled to wrap the plant, and then the lifting mechanism 2 is controlled to descend. When the lifting mechanism 2 descends, the first rack 5 controls the vibration mechanism 6 to vibrate, so that the equipment is more efficient when digging, and the grabbing assembly 36 enters the soil faster to avoid the soil being hard, which causes the soil to be hard when the equipment is digging, resulting in the equipment being unable to complete the digging. When the grabbing assembly 36 digs out the material , the alternating mechanism 21 is driven to rise by the lifting mechanism 2, and the material is dug out at this time. At the same time, the driving mechanism 29 controls the alternating mechanism 21 to move, so that the excavated material rises, and the digging assembly 37 descends, and then the support frame 1 is pushed to move, and the support frame 1 is moved to the position where transplanting is required, and then the lifting mechanism 2 is controlled to descend, and the digging assembly 37 is adjusted in cooperation with the driving mechanism 29, so that the digging assembly 37 completes the digging of the pit, and finally the material of the grabbing assembly 36 is placed in the dug pit, and the transplanting of the material is completed, making the equipment more convenient to use, and at the same time making the equipment less operated during the transplanting process, and the steps more concise, and at the same time reducing the use of equipment, avoiding the need for multiple equipment operations during the transplanting process, thereby reducing the transplanting efficiency of the equipment and reducing the hardness of the soil.
[0019] As a further solution of the present invention, the lifting mechanism 2 includes a first threaded rod 3 and a mounting plate 4, the first threaded rod 3 is rotatably connected in the support frame 1, the mounting plate 4 is threadedly connected to the first threaded rod 3, and the mounting plate 4 is slidably connected to the support frame 1; During operation, when the equipment moves to a suitable position, the first threaded rod 3 is controlled to rotate. At this time, the first threaded rod 3 controls the mounting plate 4 to descend, so that the alternating mechanism 21 can be descended, thereby completing the excavation and pit opening of the material. At the same time, when the material is excavated by the grabbing assembly 36, the reverse movement of the first threaded rod 3 can effectively control the material in the grabbing assembly 36 to move out of the ground, thereby making the equipment more convenient when excavating materials and digging pits.
[0020] As a further solution of the present invention, the vibration mechanism 6 includes a first speed regulating box 7, a one-way wheel 8, a special-shaped wheel 9, a fixing frame 10, a guide tube 11, an impact disk 12, a pull rod 13 and an elastic mechanism. The first speed regulating box 7 is installed on the lifting mechanism 2, and the first speed regulating box 7 is provided with a one-way wheel 8, the one-way wheel 8 and the first rack 5 are meshed and connected, the first speed regulating box 7 is rotatably connected with the special-shaped wheel 9, the mounting plate 4 is installed with a fixing frame 10, the fixing frame 10 is provided with a guide tube 11, the impact disk 12 is slidably connected in the guide tube 11, a pull rod 13 is provided between the special-shaped wheel 9 and the impact disk 12, and the lower side of the impact disk 12 is movably connected with an elastic mechanism; During operation, when the lifting mechanism 2 descends, the one-way wheel 8 rotates driven by the first rack 5, and the one-way wheel 8 controls the first speed regulating box 7 to start working. When the first speed regulating box 7 is working, the first speed regulating box 7 controls the special-shaped wheel 9 to rotate, so that the special-shaped wheel 9 drives the impact plate 12 to descend through the pull rod 13. As the special-shaped wheel 9 rotates, the impact plate 12 can effectively impact the elastic mechanism, causing the elastic mechanism to form an impact, which can effectively flush the grabbing assembly 36 into the ground, thereby completing the excavation of materials and making it more convenient to excavate. When the lifting mechanism 2 is reset, the one-way wheel 8 does not rotate.
[0021] As a further solution of the present invention, the elastic mechanism includes a sliding frame 14, a force disc 15 and a spring 16. The sliding frame 14 is slidably connected to the fixed frame 10, and the force disc 15 is installed on the sliding frame 14. The force disc 15 is slidably connected in the guide tube 11, and the force disc 15 and the impact disc 12 are movably connected. Two springs 16 are fixedly connected to the lower side of the sliding frame 14; During operation, when the impact plate 12 descends, the impact plate 12 impacts the force plate 15. At this time, the force plate 15 descends, and at the same time, the sliding frame 14 squeezes the spring 16, so that the spring 16 is compressed. As the impact plate 12 works repeatedly, the sliding frame 14 can move repeatedly, making the equipment more efficient in digging and pit digging, and easier to enter the soil during operation, thereby improving the digging efficiency of the equipment.
[0022] As a further solution of the present invention, the adjustment mechanism 17 includes a guide frame 18, a second threaded rod 19 and a mounting frame 20. The guide frame 18 is mounted on the vibration mechanism 6. The second threaded rod 19 is rotatably connected in the guide frame 18. The mounting frame 20 is threadedly connected to the second threaded rod 19. During operation, when the driving mechanism 29 controls the second threaded rod 19 to rotate, the second threaded rod 19 controls the mounting frame 20 to move, thereby effectively changing the positions of the material grabbing assembly 36 and the pit digging assembly 37 on the alternating mechanism 21, so that the equipment can dig materials and dig pits, thereby making the equipment more convenient to use, forming an integrated work, further reducing the use of the equipment, and speeding up the transplantation steps of the equipment.
[0023] As a further solution of the present invention, the alternating mechanism 21 includes a first rotating column 22, a second rotating column 23, a toothed disc 24, a second rack 25, a limiting groove 26, a self-locking frame 27 and a first gear 28. The first rotating column 22 and the second rotating column 23 are rotatably connected to the adjustment mechanism 17. The first rotating column 22 and the second rotating column 23 are meshingly connected. A toothed disc 24 is installed on the first rotating column 22. Two second racks 25 are meshingly connected to the toothed disc 24. The second rack 25 is slidably connected to the mounting frame 20. A limiting groove 26 is provided on the rear side of the second rack 25. A self-locking frame 27 is provided between the limiting groove 26 and the mounting frame 20. The self-locking frame 27 is slidably connected in the limiting groove 26. The first gear 28 is installed on the second rotating column 23. During operation, when the driving mechanism 29 controls the first gear 28 to rotate, the first gear 28 drives the first rotating column 22 to rotate through the second rotating column 23. At this time, the first rotating column 22 controls the rotation of the toothed disc 24. When the toothed disc 24 rotates, the two second racks 25 move. At this time, the second racks 25 will alternate up and down, so that the digging component 37 rises when the equipment is digging materials, or the grabbing component 36 rises when the digging component 37 digs a pit, so as to be recycled and allow the equipment to repeatedly dig materials and transplant them, thereby further improving the convenience and efficiency of the equipment. When the second rack 25 moves to a certain position, the self-locking frame 27 locks the second rack 25 to prevent the second rack 25 from moving.
[0024] As a further solution of the present invention, the driving mechanism 29 includes a transmission shaft 30, a third gear 31, a second speed regulating box 32, a third rotating column 33, a driving motor 34 and a telescopic rod 35. The adjustment mechanism 17 is rotatably connected to two transmission shafts 30, and the two transmission shafts 30 are transmission-connected. The transmission shaft 30 is installed with a third gear 31, and the third gear 31 is movably engaged with the alternating mechanism 21. The adjustment mechanism 17 is installed with a second speed regulating box 32, and the second speed regulating box 32 is transmission-connected to the transmission shaft 30. The adjustment mechanism 17 is rotatably connected to the third rotating column 33, and the third rotating column 33 is transmission-connected to the adjustment mechanism 17. The adjustment mechanism 17 is installed with a driving motor 34, and the output end of the driving motor 34 is fixedly connected to the telescopic rod 35, and the telescopic rod 35 is movably engaged with the third rotating column 33 and the second speed regulating box 32 respectively; During operation, when the telescopic rod 35 is shortened, the telescopic rod 35 controls the third rotating column 33 to rotate. At this time, the third rotating column 33 controls the adjusting mechanism 17 to work. At this time, the adjusting mechanism 17 controls the alternating mechanism 21 to move. When the alternating mechanism 21 moves to both sides, the alternating mechanism 21 will engage with one of the third gears 31, and then control the telescopic rod 35 to extend, so that the telescopic rod 35 and the second speed regulating box 32 are engaged. At this time, the driving motor 34 controls the transmission shaft 30 to rotate through the second speed regulating box 32. At the same time, the third gear 31 on the transmission shaft 30 can effectively control the first gear 28 in the alternating mechanism 21 to rotate, thereby completing the alternation of the alternating mechanism 21, further ensuring the transplanting and digging of the equipment, and making the equipment more convenient to use.
[0025] As a further solution of the present invention, a pull plate 38 is installed on one side of the support frame 1, and a moving wheel 39 is installed on the lower side of the support frame 1; When working, the device is moved by pulling the pull plate 38, so that the device can complete the transfer of materials and move it to the position where a pit needs to be dug, thereby forming a pit digging and transplanting of the equipment, making it more efficient when used and reducing the use of the equipment.
