When the pit digging specification is matched with the drill bit body, the lifting driving component and the drill bit body can be matched for construction; when the pit digging specification is larger than the hole forming size of the drill bit body, the drill bit body is driven by the linear driving component to move so as to adjust the position of the drill bit body relative to the central axis of the rotary disc, the rotary disc is driven by the rotary driving component to rotate, and then the pit forming size can be changed. According to the pit digging device for landscaping planting, the caliber of the formed pit body can be flexibly adjusted, so that the pit digging efficiency and the structural strength of the formed pit body are ensured.

Description

Technical Field

[0001] The present application belongs to the field of garden engineering technology, and specifically relates to a pit-digging device for garden greening and planting. Background Art

[0002] Garden engineering refers to the process of transforming a target garden into a specific beautiful landscape area through on-site construction of various garden design elements using engineering means and artistic methods. That is, within a specific range, multiple garden design elements (also called construction elements) are processed through artificial means (artistic or technical) to make the garden meet certain aesthetic requirements and artistic atmosphere. The process of implementing this project is garden engineering.

[0003] Digging holes in the land is an important process in landscaping and planting. The existing hole digging method is usually achieved by the cooperation of a drill bit and a cylinder, that is, the cylinder drives the drill bit to move toward the ground, and the drill bit rotates to break the soil to form a circular hole structure.

[0004] The inventors found that in the existing pit-digging method, the size of the drill bit directly determines the diameter of the pit body. Depending on the different plants being planted, the specifications of the pit body are often different, which requires workers to repeatedly dig holes and break the soil. On the one hand, this reduces the efficiency of pit digging, and on the other hand, it makes it difficult for the final pit body to maintain a round pit state, affecting the subsequent planting process.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0044] Please also refer to Figures 1 to 5 The garden greening planting hole digging device provided by the present application is now described. The garden greening planting hole digging device proposed in the present application includes a cart body 1, a turntable 2 and a drill body 3.

[0045] The trolley body 1 is used to be supported on the ground and move in a horizontal direction. The trolley body 1 has an inner cavity 11 , and a through hole 12 communicating with the inner cavity 11 is formed on a lower side thereof.

[0046] It should be noted that the outer peripheral surface of the cart body 1 is structured by a plurality of support plates, so that gaps for human observation are formed between adjacent support plates.

[0047] The turntable 2 is disposed in the inner cavity 11 and is transmission-connected to a lifting drive member 4 so as to enable the turntable 2 to move in an up-down direction relative to the cart body 1 .

[0048] The turntable 2 is also transmission-connected to a rotation driving member 5 so as to be adapted to rotate relative to the cart body 1 about its own central axis.

[0049] It should be noted that the rotation and lifting of the turntable 2 will not interfere with each other, that is, the rotation and lifting of the turntable 2 can occur simultaneously.

[0050] The drill body 3 is slidably connected to the lower side of the turntable 2, and its sliding direction is perpendicular to the up and down direction and is arranged toward the central axis of the turntable 2. The drill body 3 is transmission-connected to a linear drive member 6 to move it toward or away from the central axis of the turntable 2.

[0051] The rotary disc 2 is driven downward by the lifting drive member 4 so that the lower end of the drill body 3 can pass through the through hole 12 and extend out to be connected with the ground.

[0052] In the embodiment of the present application, by cooperating with the lifting drive component 4 and the drill body 3, the drill body 3 in a rotating state is drilled into the ground, thereby completing the operation of drilling a hole in the ground; on this basis, if it is necessary to expand the diameter of the formed pit, the drill body 3 can be driven to move by the linear drive component 6 to adjust the position of the drill body 3 relative to the central axis of the turntable 2, and the turntable 2 can be driven to rotate by the rotating drive component 5 to achieve the change of the pit size.

[0053] Compared with the prior art, the pit-digging device for landscaping and planting provided in this embodiment can flexibly adjust the diameter of the pit body to ensure the pit-digging efficiency and the structural strength of the pit body.

[0054] In some embodiments, as Figure 3 and Figure 4 As shown, the lower side of the turntable 2 has a coaxial annular guide ring 21, and the inner bottom surface of the inner cavity 11 has a telescopic rod 7 that is arranged around the through hole 12 and is slidably connected to the guide ring 21 along the circumference of the guide ring 21.

[0055] By adopting the above technical solution, on the basis of ensuring that the turntable 2 can move in the up and down directions, the telescopic rod 7 can prevent the turntable 2 from moving in the horizontal direction, thereby preventing the turntable 2 from being misplaced on the horizontal plane.

[0056] In some embodiments, as Figure 4 As shown, the telescopic rod 7 includes a fixed shaft sleeve 71 and a sliding connecting rod 72.

[0057] The fixed sleeve 71 is fixedly connected to the inner bottom surface of the inner cavity 11 and has a slot 711 facing upward.

[0058] The sliding link 72 is inserted into the slot 711 by sliding in the up and down directions, and is connected to the guide ring 21 by sliding along the circumference of the guide ring 21; specifically, the upper end of the sliding link 72 has a convex ball portion, and the lower side surface of the guide ring 21 has a concave ball groove that is connected end to end and is annular; the convex ball portion and the concave ball groove cooperate to realize the connection between the sliding link 72 and the guide ring 21.

[0059] In some embodiments, as Figures 2 to 4 As shown, the turntable 2 has a strip hole 22 that passes through in the up-down direction and extends in its radial direction. The upper end of the drill body 3 has a protrusion 311 that passes through the strip hole 22 and extends out to achieve a sliding connection between the drill body 3 and the turntable 2.

[0060] In some embodiments, as Figure 2 As shown, the linear drive component 6 is a first linear cylinder fixedly connected to the upper side of the turntable 2 , with the power output axis parallel to the length direction of the strip hole 22 .

[0061] In some embodiments, as Figure 5 As shown, the drill body 3 includes a sliding seat 31 and a drill rod 32 .

[0062] The sliding seat 31 is slidably connected to the lower side of the turntable 2, and is fixedly connected to a first rotating motor 312 with a power output axis parallel to the up-down direction and a power output end facing downward.

[0063] The drill rod 32 is coaxially connected to the power output end of the first rotary motor 312 and has a spiral blade 321 extending radially outward.

[0064] When the lower end of the drill rod 32 contacts the ground and moves downward synchronously with the turntable 2, the drill rod 32 and the blade 321 act on the ground synchronously to achieve drilling of the area.

[0065] In some embodiments, as Figure 4 and Figure 5 As shown, a protective shell 313 is connected to the lower side of the sliding seat 31 and covers the outer periphery of the first rotating motor 312.

[0066] In some embodiments, as Figures 1 to 4 As shown, the lifting drive component 4 includes a second linear cylinder 41 and a transmission plate 42 .

[0067] The second linear cylinder 41 is fixedly mounted on the upper side of the trolley body 1 through a bracket 411, and its power output axis is parallel to the up and down direction; specifically, the bracket 411 is fixedly mounted on the upper side of the trolley body 1 and is located directly above the turntable 2; the second linear cylinder 41 is fixedly mounted on the bracket 411, and its power output end faces downward.

[0068] The transmission disk 42 is coaxially arranged on the upper side of the turntable 2 and is rotationally connected to the turntable 2; specifically, the upper side surface of the turntable 2 has an upwardly extending, annular fixed ring, and the outer edge of this transmission disk 42 has a downwardly extending docking ring that covers the outer periphery of the fixed ring; wherein, the outer peripheral surface of the fixed ring and the inner peripheral surface of the docking ring respectively have protrusions and recesses to realize the rotational connection between the two.

[0069] In this embodiment, a reserved hole 13 communicating with the inner cavity 11 is opened on the upper side of the cart body 1. The power output shaft of the second linear cylinder 41 passes through the reserved hole 13 and is connected to the transmission disk 42, so as to drive the transmission disk 42 to move in the up and down directions without interfering with the rotation of the turntable 2.

[0070] In some embodiments, as Figure 2 branch Figure 4 As shown, the rotation driving member 5 includes a driving gear 51 and a driven gear 52 .

[0071] The driving gear 51 is disposed in the inner cavity 11 , with its axial direction parallel to the up-down direction, and is transmission-connected to a second rotating motor 511 for driving it to rotate relative to the cart body 1 about its own central axis.

[0072] The driven gear 52 is fixedly mounted on the rotary disk 2 and meshes with the driving gear 51 .

[0073] By adopting the above technical solution, when the second rotating motor 511 is started, the driving gear 51 drives the driven gear 52 to rotate, so that the turntable 2 rotates relative to the cart body 1.

[0074] It should be noted that in the vertical direction, the driving gear 51 is longer than the driven gear 52 so that when the lifting drive component 4 drives the turntable 2 to move, the driving gear 51 can maintain a meshing relationship with the driven gear 52.

[0075] In some embodiments, as Figure 4 As shown, the second rotating motor 511 is fixedly arranged on the upper side of the cart body 1, and its power output shaft passes through the upper side of the cart body 1 and is connected to the driving gear 51; based on this, since the height of the driving gear 51 is limited and there is a distance between the bottom end of the driving gear 51 and the inner bottom surface of the inner cavity 11, in order to improve the structural strength of the driving gear 51 relative to the cart body 1, the inner bottom surface of the inner cavity 11 is further provided with a support portion 14 extending upward and abutting against the driving gear 51.

[0076] The above content is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
