Description

Technical Field

[0001] The utility model relates to the technical field of pit digging equipment, in particular to a pit digging equipment for vegetation maintenance. Background Art

[0002] Digging equipment is widely used in gardening and greening projects for digging holes for planting vegetation on sloping land, sandy land, and hard land, digging the outer perimeter of large trees, digging holes for burying fence stakes, and digging holes for fertilizing fruit trees and trees. It is one of the indispensable machines in gardening and greening projects.

[0003] After searching, the utility model patent announcement number is CN 208675719 U. The utility model relates to the technical field of garden machinery, especially a digging machine for planting garden vegetation, including a support ring plate and a base, and a rotator is fixedly installed on both sides of the upper outer wall of the base. The utility model is equipped with four support devices on the upper surface of the support ring plate, and the support device is composed of a slide bar, a clamping pin and a fixed sleeve. At the same time, the support assembly is fixedly connected to the digging machine base through a fixer. In the intermittent process of digging a pit, the support assembly is supported by the clamping pin, and the digging machine is placed vertically in conjunction with the support ring plate. At the same time, a tape measure is installed inside the four receiving grooves opened inside the support ring plate, and a tape measure is installed inside the tape measure. The tape measure passes through the support ring plate, and the tape measure is pulled out by a pull ring, so that the tape measure is used to directly measure and locate the position of the next digging pit, reducing the preliminary measurement steps and improving work efficiency.

[0004] Existing pit digging equipment will throw the soil produced by the pit to the surrounding area when digging. When there is a lot of soil, the soil will roll into the pit, resulting in inaccurate depth of the pit, causing certain impressions on the growth in the later stage of planting. Utility Model Content

[0007] By adopting the above technical scheme, the mobile vehicle is pushed to the digging position, and then the electric telescopic rod is driven to extend and retract to drive the motor spiral drill bit to descend. When the spiral drill bit descends, it drives the fixed plate and the limiting sleeve to descend, and the limiting sleeve descends to drive the spring, the rotating plate and the cleaning plate to descend. When the cleaning plate contacts the ground, the rotating plate contracts like the inside of the limiting sleeve, so that the spring inside the limiting sleeve is squeezed by the contraction of the rotating plate.

The soil produced by digging the hole is thrown out of the surface side of the digging hole by the spiral drill bit, and the rotating cleaning plate cleans the soil on the surface of the digging hole to prevent the soil on the surface of the digging hole from falling into the digging hole. When the spiral drill bit is retracted through the electric telescopic rod after digging the hole, the extruded spring ejects the rotating plate through the limiting sleeve through the elastic force.

[0017] By adopting the above technical solution, rapid cleaning of the soil is ensured.

[0018] Optionally, a long groove is formed at the inner upper end of the support frame.

[0019] By adopting the above technical solution, it is convenient for parts to rotate.

[0020] Optionally, a limit plate is fixedly connected to the upper end of the surface of the rotating plate, and the size of the limit plate is adapted to the size of the internal groove of the limit sleeve.

[0021] By adopting the above technical solution, the rotating plate is prevented from being ejected from the inside of the limiting sleeve due to the elastic force of the spring.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The technical solution of the present application is to push the mobile vehicle to the digging position, and then drive the electric telescopic rod to extend and retract to drive the motor spiral drill bit to descend. When the spiral drill bit descends, it drives the fixed plate and the limiting sleeve to descend. The limiting sleeve descends and drives the spring, the rotating plate and the cleaning plate to descend. When the cleaning plate contacts the ground, the rotating plate contracts like the inside of the limiting sleeve, so that the spring inside the limiting sleeve is squeezed by the contraction of the rotating plate. When the spiral drill bit contacts the soil surface, the driving motor drives the spiral drill bit to rotate, and the rotating spiral drill bit rotates to dig a hole in the soil. The rotating cleaning plate cleans the soil on the surface of the pit and prevents the soil on the surface of the pit from falling into the pit. When the pit is dug, the spiral drill bit is retracted through the electric telescopic rod, and the rotating plate is ejected through the limiting sleeve by the elastic force of the extruded spring. The structure is simple and easy to operate, and the soil dug out from the pit can be cleaned to prevent the soil from falling into the pit. BRIEF DESCRIPTION OF THE DRAWINGS
