Description

Technical Field

[0001] The utility model relates to the technical field of garden greening, in particular to a pit digging device for garden greening planting. Background Art

[0002] In landscaping, plants usually need to be planted or transplanted in order to better design and plan the garden. Before planting or transplanting trees, a hole digger is used to dig a hole at the target location, and then the trees to be planted are placed in the hole to bury their roots to complete the planting of the trees.

[0003] Existing pit digging machines typically dig uniform-sized pits. However, due to the varying sizes of plant root balls, larger root balls cannot fit into the pits, and filling the pits with smaller root balls is time-consuming and labor-intensive. Furthermore, digging a large pit at once can be difficult in hard soil or where the soil is heavily rooted. Utility Model Content

DETAILED DESCRIPTION

[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are 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 making creative efforts are within the scope of protection of the present invention.

[0019] The following is combined with Figure 1-3 The utility model is further described as follows:

[0020] A digging device for landscaping planting includes a lower box body 1, an upper box body 2 is provided on the top of the lower box body 1 through a rotating device 3, a lifting device 4 is provided on the front and rear side walls of the upper box body 2, a rocker device 6 is provided between the two lifting devices 4 and passes through the upper box body 2, and a digging device 5 fixedly connected to the rocker device 6 is provided on the left and right side walls of the upper box body 2.

[0021] In this embodiment, the two excavating devices 5 are used for the first digging and the second digging respectively, the rocker arm device 6 is used to adjust the angle of the excavating device 5, the lifting device 4 is used to drive the excavating device 5 to lift and lower for excavating, and the rotating device 3 is used to drive the upper box body 2 to rotate to replace the two excavating devices 5.

[0022] The rotating device 3 includes a groove 31 and a boss 32. A groove 31 is provided at the center of the top surface of the lower box body 1, and a boss 32 is provided at the center of the bottom surface of the upper box body 2. The boss 32 is rotatably provided in the groove 31. An annular groove 33 is provided on the top surface of the lower box body 1 outside the groove 31, and a plurality of rotating balls 34 are rotatably provided on the bottom surface of the upper box body 2 outside the boss 32. The rotating balls 34 cooperate with the annular groove 33. A rotating motor 35 is fixedly provided at the bottom center of the lower box body 1, and a rotating main shaft 36 is fixedly provided at the output end of the rotating motor 35. The top of the rotating main shaft 36 passes through the lower box body 1 and is fixedly connected to the boss 32.

[0023] In this embodiment, the rotating motor 35 drives the upper housing 2 to rotate via the rotating spindle 36. The boss 32 is locked in the groove 31, which can ensure a tighter connection between the lower housing 1 and the upper housing 2, effectively preventing misalignment and tilting of the upper housing 2 during rotation. The rotating ball 34 rotates along the annular groove 33, which not only reduces friction but also further improves the positioning effect.

[0024] The lifting device 4 includes two slide rails 45 fixedly arranged on the side wall of the upper box body 2, and a slider 46 is slidably arranged on the slide rails 45. A lifting bracket 44 is arranged between the two sliders 46. A lifting nut seat 47 is arranged in the middle of one of the lifting brackets 44, and a lifting screw 43 that matches the lifting nut seat 47 is rotatably arranged inside the lifting nut seat 47. The upper end of the lifting screw 43 is fixedly connected to the output end of the lifting motor 42, and the lifting motor 42 is fixedly connected to the side wall of the upper box body 2 through the mounting seat 41.

[0025] In this embodiment, the lifting motor 42 drives the lifting bracket 44 to slide up and down along the slider 46 and the slide rail 45 through the lifting screw 43 and the lifting nut 47. The lifting bracket 44 drives the excavating device 5 to move up and down to excavate through the rocker device 6.

[0026] The rocker device 6 includes a rocker main shaft 61 that passes through the upper box body 2. Lifting slots 62 are provided on the front and rear side walls of the upper box body 2. A rocker motor 63 is fixedly provided on the outside of one of the lifting brackets 44. The output shaft of the rocker motor 63 is fixedly connected to one end of the rocker main shaft 61, and the other end of the rocker main shaft 61 is rotatably connected to the other lifting bracket 44.

[0027] In this embodiment, the rocker motor 63 drives the two excavating devices 5 via the rocker spindle 61 to adjust their angles, so that one excavating device 5 is perpendicular to the ground and the other excavating device 5 is tilted upward. This ensures that while the excavating device 5 perpendicular to the ground is digging, the other excavating device 5 does not contact the ground. Preferably, when the lift motor 42 drives the lift bracket 44 to slide up and down along the slider 46 and the slide rail 45, the rocker spindle 61 slides up and down along the lift slot 62.

[0028] The excavation device 5 includes an excavation motor 53, and a spiral drill 54 is fixedly provided at the output end of the excavation motor 53. One side of the excavation motor 53 is fixedly connected to the output end of the extended telescopic arm 51. Rocker arm grooves 52 are provided on the left and right side walls of the upper box body 2. The extended telescopic arm 51 passes through the rocker arm grooves 52 and is fixedly connected to the rocker arm main shaft 61. The diameters of the two spiral drills 54 are different.

[0029] In this embodiment, a lifting motor 42 drives a lifting bracket 44 to slide up and down along a slide block 46 and a slide rail 45 via a lifting screw 43 and a lifting screw nut 47. The lifting bracket 44 drives an extended telescopic arm 51 to slide up and down along a rocker arm slot 52 via a rocker arm spindle 61. A digging motor 53, perpendicular to the ground, drives an auger 54 to rotate and dig the soil. Preferably, the extended telescopic arm 51 can be extended and retracted to adjust the distance of the auger 54.

[0030] In this embodiment, a smaller auger 54 is directly used to drill holes for smaller root balls. For larger root balls and harder or more root-rich ground, a secondary drilling may be performed.

[0031] The rocker motor 63 first adjusts the smaller diameter auger 54 to be perpendicular to the ground, the digging motor 53 drives the smaller diameter auger 54 to rotate, and the lifting motor 42 drives the smaller diameter auger 54 downward to perform the first digging. After the first digging is completed, the lifting motor 42 drives the smaller diameter auger 54 to rise, and the rocker motor 63 stops rotating.

[0032] The rotating motor 35 drives the upper box body 2 to rotate 180 degrees, the rocker motor 63 adjusts the larger diameter spiral drill 54 to be perpendicular to the ground so that it is aligned with the tree pit dug for the first time, the digging motor 53 drives the larger spiral drill 54 to rotate, and the lifting motor 42 drives the larger diameter spiral drill 54 to move downward for the second digging.

[0033] In summary, the present invention is not limited to the above-described specific embodiments. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. The scope of protection of the present invention shall be based on the claims of the present invention.
