Description

Technical Field

[0001] This invention relates to the field of tree pit laying technology, specifically to an adjustable tree pit laying device. Background Technology

[0002] In landscape construction, the marking of tree pits for incoming seedlings is indispensable. As an important construction procedure, marking has multiple significances, such as marking the planting pits before excavation and shortening the excavation time.

[0003] In existing technologies, firstly, the marking of tree pits for seedlings is mainly done manually using tools such as rulers, straw ropes, wooden branches, shovels, and lime, which is time-consuming and labor-intensive. Secondly, in the traditional manual tree pit excavation and marking process, deviations occur in the marking of tree pits of the same size, resulting in inconsistent sizes of manually excavated tree pits, which affects the growth of seedlings of the same size. Thirdly, the manual marking of tree pits using lime powder can easily burn the skin. Some methods involve putting lime into the shovel, which causes unevenness and blurring of lines during the lime spreading process, affecting the excavation process. Fourthly, current mechanical tree pit excavation has certain limitations in terms of the size of the tree pits. It can only excavate tree pits of a certain size and cannot adapt to the excavation of tree pits of various sizes. When dealing with tree pits larger than those excavated by machines, there are no suitable marking and excavation tools to assist in the excavation, resulting in inconsistent tree pit sizes in mechanical excavation.

[0004] In summary, based on past project construction experience, relevant references, and research on other projects, it is not difficult to find that in the process of landscaping planting construction, most tree pits are excavated manually, and a few are excavated mechanically. Regardless of whether it is manual or mechanical excavation, there is no good device for setting out the size of the tree pits. Considering the time, manpower, material resources, cost, and safety factors of excavating tree pits, an adjustable tree pit setting-out device is invented to solve the above-mentioned technical problems.

[0036] When in use, the leveling instrument 8 is a leveling tool with an internal balance bubble. With the help of the manual handrail 40, the cone 12 is inserted into the site, and a circle is drawn with this as the center to ensure the accuracy of the tree pit size. The scale is in decimeters, and the telescopic sleeve 13 has a 1-meter scale. The size of the tree pit can be determined according to the diameter at breast height of the seedling, and the size of the tree pit can be determined based on this. The rotating platform 1 can be rotated by the bearing 10, which helps the rotating platform 1 to rotate around the center. The rotating platform 1 is provided with a support plate 37 on the side, which helps with manual handling and removal after positioning and laying out. The through hole 41, together with the positioning column 3, can easily fix the telescopic sleeve 13. The lifting screw 7 can be adjusted to different heights by rotating in the lifting tube 6, which makes it convenient for workers of different heights to use. All the structures are connected by threads, which can be easily disassembled.

[0037] Example 3

[0038] Based on Embodiment 2, a second telescopic sleeve 15 is provided, which can move within the telescopic sleeve 13. A damping rubber pad 43 is provided on the surface of the second telescopic sleeve 15, contacting the inner surface of the telescopic sleeve 13. A limit block 44 is provided on the surface of the second telescopic sleeve 15, inserted into a limit hole 42. A scale 14 is also provided on the side of the second telescopic sleeve 15. The overall structure of the third telescopic sleeve 16 is the same as that of the second telescopic sleeve 15. The hopper 20 is glued into a hole on the surface of the adjusting plate 19. A marking plate 45 is provided on the surface of the adjusting plate 19. The bottom of the adjusting plate 19 is provided with a rotating rod 46, and one end of the rotating rod 46 is provided with a universal wheel 47. The adjusting plate 19 can slide on the hydraulic lifting rod 18. The baffle 31 has a square plate structure. The second bearing 32 is fixedly connected to the lower surface of the baffle 31. The support plate 34 can be moved on the positioning screw 33 by rotating the positioning screw 33. The bottom of the positioning rod 35 is fixedly connected to the surface of the support plate 34.

The anti-slip ball 36 provided at one end of the positioning rod 35 has a certain elasticity.

[0039] When in use, the hopper 20 is a line-laying device for powdery markers. After determining the size of the telescopic sleeve 13, the handrail 40 is manually rotated with the cone 12 as the center to lay out the tree pit. The telescopic sleeve 13 serves as a reference for laying out the tree pit size. It contains a second telescopic sleeve 15 and a third telescopic sleeve 16. This component can extend up to 3 meters. Of course, this component can be disassembled and used as a reference ruler for the depth of tree pit excavation. The damping rubber pad 43 prevents the second telescopic sleeve 15 and the third telescopic sleeve 16 from moving randomly. When the adjusting plate 19 is displaced on the hydraulic lifting rod 18, the positioning screw 33 can be rotated to make the anti-slip ball 36 at one end of the positioning rod 35 make tight contact with the bottom of the telescopic sleeve 13 or the bottom of the second telescopic sleeve 15 and the third telescopic sleeve 16 to prevent the adjusting plate 19 from moving again.

[0040] In actual use, the leveling instrument 8, lifting pipe 6, scale 14, rotating platform 1, cone 12, hopper 20, and telescopic sleeve 13 can be used to lay out the tree pits according to the size of different specifications of seedlings and the reference depth of excavation. This allows for quick laying out of the tree pits, reducing the complicated process of traditional line laying. After the tree pits are laid out, the telescopic sleeve 13 can be disassembled to control the excavation depth of the tree pits. The hopper 20 and scale 14 improve the accuracy of the tree pit size while preventing workers from getting burned during line laying. This device not only improves work efficiency and saves costs, but also facilitates the standardization of tree pit sizes for the same specifications of seedlings.
