DETAILED DESCRIPTION

[0028] 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.

[0029] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0030] In some municipal greening projects, due to limited construction sites, if the soil stacking problem after digging is not properly handled, it may hinder the smooth progress of other construction links. For example, when carrying out greening construction in narrow streets or parks with limited space, randomly stacked soil may hinder traffic or affect the normal use of surrounding facilities. In order to solve this problem, a portable digging device for municipal greening planting is set up to solve the above problem. The operation is as follows:

[0031] Combination Figure 1-Figure 5 The portable pit digging device for municipal greening planting of the present invention comprises a rotating drum 11, an operating handle 12 is fixedly connected to the outer surface of the rotating drum 11, and a digging head 14 is connected to the bottom end of the rotating drum 11. During greening planting, the rotation of the rotating drum 11 drives the rotation of the digging head 14 until the digging head 14 is embedded in the soil, thereby realizing the pit digging operation. The specific operation is as follows:

[0032] A positioning assembly 3 is embedded in the drum 11, and the positioning assembly 3 includes a cover 33, an electric pressure rod 13 is embedded in the cover 33, and a spacer 35 is connected to the bottom end of the electric pressure rod 13. A return spring 34 is sleeved on the outer surface of the output end of the electric pressure rod 13, and a pressure plate 31 is sleeved on the outer surface of the electric pressure rod 13. The bottom end of the pressure plate 31 is connected to a cutting rod 32, and six groups of cutting rods 32 are provided. The bottom ends of the six groups of cutting rods 32 are set to be conical. The cutting rods 32 penetrate the cover 33 and the interior of the spacer 35 until they extend to the lower surface of the spacer 35. The cutting rods 32 and the spacer 35 are slidably connected, and the bottom ends of the cutting rods 32 are embedded in the interior of the spacer 35. The drum 11 and the spacer 35 are slidably connected, and a sealing ring is provided on the outer surface of the spacer 35.

[0033] A separation component 2 is embedded in the interior of the rotating drum 11, and the separation component 2 includes an isolation ring 24. An isolation ring 24 is embedded in the interior of the rotating drum 11. A main tube 21 is provided on the outer surface of the rotating drum 11, and a secondary tube 28 is connected to one side of the main tube 21. The main tube 21 and the rotating drum 11 are rotatably connected. A gear ring is fixedly connected to the outer surface of the rotating drum 11, and a transmission tooth 26 is meshed with the gear ring. A motor 25 is installed inside the secondary tube 28. A connecting block is connected between the main tube 21 and the secondary tube 28, and the connecting block is used to fix the main tube 21 and the secondary tube 28 together. A first group of through grooves is provided between the main tube 21, the secondary tube 28 and the connecting block. One side of the transmission tooth 26 is embedded in the first group of through grooves and meshes with the gear ring. An output end of the motor 25 is connected with a driving tooth 27. A transmission tooth 26 is also provided inside the tube 28, an inner slot 22 is provided at one end of the left side of the auxiliary tube 28, a separator 23 is embedded inside the auxiliary tube 28, another second set of through slots is provided between the rotating drum 11, the main tube 21, the auxiliary tube 28 and the connecting block, the height of the second set of through slots corresponds to the inner slot 22, the separator 23 is set in a circular ring shape, and a magnetic sheet is provided on the lower surface of the separator 23, the separator 23 is embedded into the inside of the rotating drum 11 through the second set of through slots, the upper surface of the isolation ring 24 is provided with a magnetic sheet corresponding to the lower surface of the separator 23, the separator 23 is pushed from the inside of the auxiliary tube 28 to the inside of the rotating drum 11 by a push rod and is mounted on the upper surface of the isolation ring 24, the upper surface of the transmission tooth 26 is set as a plane, and the lower surface of the transmission tooth 26 is set as an inclined surface;

[0034] When digging a hole, first turn on the motor 25. When the motor 25 starts to rotate, it drives the active gear 27 to rotate. When the active gear 27 rotates, it drives the transmission gear 26 to rotate. Since the transmission gear 26 is meshed with the toothed ring installed on the outer surface of the rotating drum 11, after the transmission gear 26 rotates, it is transmitted to the toothed ring to drive the rotating drum 11 to rotate. When the rotating drum 11 rotates inside the main barrel 21, it contacts the soil through the digging head 14, cuts the soil as it rotates, and the soil after cutting is embedded in the inside of the rotating drum 11. The soil is then collected by the rotating drum 11. As the rotating drum 11 is pulled out of the soil, a hole for planting is formed.

[0035] In order to allow the soil to remain inside the drum 11 and thus be taken out of the pit, the separator 23 is pushed so that the separator 23 is embedded into the drum 11. When the separator 23 is embedded into the drum 11, the soil is cut. After cutting, the separator 23 is mounted on the upper surface of the isolation ring 24. At this time, the soil blocks are also stored on the upper surface of the separator 23. In this way, the soil blocks generated by digging the pit can also be well stored inside the drum 11, thus avoiding the problem of soil being scattered randomly during the digging stage.

[0036] During the planting stage, the seeds are placed in the dug holes and the soil produced by the original digging is then backfilled into the holes. The operation is also more convenient. It is only necessary to extract the partition sheet 23 embedded in the rotating drum 11 again, and then embed it into the auxiliary drum tube 28. When the soil block loses the support of the partition sheet 23, it will fall out of the inside of the rotating drum 11. At this time, the fallen soil block is backfilled into the holes to complete the backfilling.

[0037] In addition, a positioning assembly 3 is provided. After digging the pit, the soil blocks left inside the rotating drum 11 are relatively compact, and a certain air permeability is required for planting and germination. Therefore, by pressing the pressing plate 31, the pressing plate 31 drives the cutting rod 32 to descend. When the cutting rod 32 descends, it will be inserted into the soil blocks, so that the soil blocks can be loosened and form air holes for air circulation.

[0038] Finally, when the soil is filled into the hole, the isolation plate 35 is driven by the output end of the electric pressure rod 13, so that the isolation plate 35 passes through the hole inside the isolation ring 24 and hits the soil, thereby compacting the backfilled hole.
