Description

Technical Field

[0001] The utility model relates to the technical field of horticultural planting machinery, and particularly relates to a multi-soil pit synchronous excavation device for green plant transplantation. Background Technique

[0002] The transplantation of trees in landscaping projects involves multiple steps such as excavating soil pits, transportation, transplantation, replenishing soil, watering and fertilizing. During the process of excavating soil pits, it is difficult for manual operation to ensure the consistency of the shape and size of the soil pits. In the patent with the application number CN202121919747.9, a planting pit digging device for landscaping tree transplantation is proposed. By using a drill bit with spiral blades, regular planting pits with a certain diameter can be dug, providing a larger embedded placement space for the transplantation of landscaping trees and ensuring the smooth progress of the transplantation of landscaping trees. However, during the excavation of this device, the soil is prone to accumulate near the excavation pit and cause collapse, resulting in the soil falling back into the excavation pit again, affecting the consistency of the soil pit, and it needs to be excavated one by one, with low efficiency.

[0023] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] A multi-soil pit synchronous excavation device for green plant transplantation, please refer to Figures 1-4 , which includes a cantilever 1, a connecting plate 2 fixedly connected below the cantilever 1, and a transplanting claw 3 fixedly connected below the connecting plate 2. The cantilever 1 is connected to a vehicle. A plurality of transplanting claws 3 are connected below the connecting plate 2 by bolts and are distributed longitudinally and horizontally; the connecting plate 2 and the cantilever 1 are detachable. Moving this device can excavate the surface soil at different positions, which is beneficial to the unified batch transplantation of green plants.

[0025] Among them, the transplanting claw 3 includes a mounting frame 31, a bent arm 32 rotatably connected to the mounting frame 31 relatively in the middle, a digging shovel 34 connected below the bent arm 32, and a driving part 35 for driving the bent arm 32 to rotate; the inner wall of the digging shovel 34 is concave.

[0026] The mounting frame 31 includes an upper frame body 311, a lower frame body 312 arranged parallel to the upper frame body 311, and a longitudinal rod 313 connecting the upper frame body 311 and the lower frame body 312. The upper frame body 311 is connected to the connecting plate 2 by bolts. The bent arm 32 is hinged to the lower frame body 312 at its middle part, and at least three bent arms 32 are evenly distributed and connected to the lower frame body 312 in its circumferential direction; the driving part 35 is a cylinder fixedly connected to the center of the lower surface of the upper frame body 311. The output end of the cylinder faces downward and is fixedly connected to a moving part 36. A short rod 37 is rotatably connected to the side of the moving part 36. A slot 371 is provided on the surface of the short rod 37, and a pin shaft 372 is fixedly connected between the two side walls of the slot 371; the upper end of the bent arm 32 extends into the inner side of the lower frame body 312, and a strip-shaped groove 321 is provided on the surface of this end. The upper end of the bent arm 32 extends into the slot 371, and the pin shaft 372 is slidably connected to the strip-shaped groove 321. When the cylinder contracts, it drives the short rod 37 to rotate, and the end cover drives the bent arm 32 to rotate, driving the plurality of digging shovels 34 in the circumferential direction to turn downward and dig simultaneously, forming a funnel-shaped soil pit for convenient transplantation of green plants. When the cylinder extends, each component resets to complete a digging process.

[0027] Among them, the moving member 36 includes a central portion 361 connected to the output end of the cylinder and a plurality of finger portions 362 radially extending from the central portion 361. Each finger portion 362 is hinged to a short rod 37. By synchronously driving the plurality of finger portions 362 to move through the cylinder, the plurality of short rods 37 and the bent arm 32 are driven to rotate, so that the digging shovel 34 synchronously digs the soil.

[0028] As an implementation manner of the present utility model, the digging shovel 34 is fixedly connected to the end of the bent arm 32 and forms an obtuse angle with the bent arm 32. The digging shovel 34 rotates with the bent arm 32 to directly dig the soil, and has high structural strength;

[0029] As an implementation manner of the present utility model, the upper end of the digging shovel 34 has an extension rod 341. The extension rod 341 is hinged to the lower end of the bent arm 32 at its end. A connecting rod 33 is also hinged below the outer side of the lower frame body 312. The extension rod 341 is hinged to the end of the connecting rod 33 at the middle thereof. In this embodiment, the connecting rod 33 plays a role in stabilizing the digging shovel 34 and guiding. When the bent arm 32 rotates downward, the digging shovel 34 synchronously rotates slightly inward, that is, the lower cutting edge of the digging shovel 34 gradually rotates from an inclined state to a horizontal state, so as to be more conducive to digging the soil.

[0030] The above-described embodiments merely describe the preferred implementation manners of the present utility model, and do not limit the concept and scope of the present utility model.
