Technical Field

[0001] The utility model relates to the technical field of tree maintenance, in particular to an inserting type maintenance device. Background Art

[0002] A roadside tree green belt refers to a green belt arranged between the sidewalk and the driveway, mainly planted with roadside trees. It has the functions of reducing road noise, purifying urban air, increasing urban greening, absorbing automobile exhaust, providing shade, and relieving visual fatigue. The management and maintenance of municipal roadside trees is an important part of urban road maintenance and is of great significance.

[0003] Since most municipal street trees are arranged on pedestrian walkways, the footpath base is hard and the soil is compacted, resulting in a shallow depth of watering and fertilizing. The roots of the street trees float in the shallow soil, causing the road surface to be arched, destroying the flatness and comfort of the road surface. In addition, the street trees are easily blown down in windy weather, posing a safety hazard. There is an urgent need for a maintenance device that can deeply water and fertilize street trees to ensure deep fertilization of street trees, avoid floating roots, cause damage, and create safety hazards. Utility Model Content

[0004] Aiming at the problem that the watering and fertilizing depth of the existing roadside trees is shallow, which causes the roots to float up, the utility model provides an insertable maintenance device.

[0005] The utility model discloses an insert-type maintenance device comprising: an insertion component and a liquid supply component, the insertion component comprising a drill rod driving component and a drill rod component, the drill rod component being detachably connected to the driving end of the drill rod driving component, and the drill rod driving component driving the drill rod component to rotate and drill holes in the ground, a hollow cavity being provided in the middle of the drill rod component, a liquid outlet hole connecting the hollow cavity with the outside world being provided on the circumferential side of the drill rod component, at least one of the liquid outlet holes being provided at one end of the drill rod component away from the drill rod driving component; and a liquid supply component being arranged on one side of the drill rod driving component and supplying liquid to the hollow cavity.

[0006] Preferably, there are three liquid outlet holes at a height, and the holes are arranged at equal distances along the central axis of the drill rod.

[0007] Preferably, the number of the liquid outlet holes at the same height is four, and they are arranged at equal angles along the circumference of the drill rod.

[0008] Preferably, the drill rod is fixedly connected to a filter located in the middle of the liquid outlet.

[0009] Preferably, the insertion assembly further comprises a movable tube, which is movably sleeved in the hollow cavity and is provided with a communicating hole located opposite to the liquid outlet. A drill bit is fixedly connected to one end of the movable tube away from the drill rod drive component, and the drill bit is located outside the hollow cavity.

[0010] Preferably, a clamping block is fixedly connected to the outer circumference of the movable tube, and the clamping block limits the movable path and distance of the movable tube.

[0011] Preferably, the insertion assembly further includes an elastic member, which is disposed between the top wall of the hollow cavity and the movable tube, and has two ends connected to the two respectively.

[0012] Preferably, the liquid supply assembly includes a liquid storage tank and a liquid infusion pipe. The liquid storage tank is arranged on one side of the drill rod driving component. The liquid infusion pipe is arranged between the liquid storage tank and the hollow cavity, and transports the curing liquid in the liquid storage tank into the hollow cavity.

[0013] Preferably, the liquid supply assembly also includes a liquid supply drive, which is fixedly installed at one end of the liquid storage tank. The drive end of the liquid supply drive is connected to one end of the infusion tube, and transports the curing liquid in the liquid storage tank to the hollow cavity through the infusion tube.

[0014] Preferably, an insertable maintenance device further includes a coiled tube assembly, which is disposed on one side of the infusion tube and is used to store and support the infusion tube.

[0015] Compared with the prior art, the present invention provides an insertable maintenance device with the following beneficial effects:

[0016] 1. This insertable maintenance device is equipped with a drill rod with a hollow cavity and a liquid outlet. When curing liquid needs to be injected into the street trees, the drill rod can be driven to rotate by the drill rod driving member, thereby extending the drill rod to a specified length. Then, curing liquid can be supplied to the hollow cavity of the drill rod through the liquid supply assembly, so that the curing liquid can flow out through the liquid outlet and directly provide nutrients to the deeper parts of the street trees, allowing the roots of the street trees to grow downward. This avoids the problem that traditional watering and fertilizing methods easily cause the roots of street trees to float up, resulting in damage to the road surface and easy blowing down in strong winds, posing a safety hazard.

[0017] 2. The insert-type maintenance device adds a movable tube and an elastic member inside the drill rod. When drilling through the drill rod, the movable tube overcomes the elastic force of the elastic member under the action of pressure at the drill bit and contracts inward, thereby causing the connecting hole starting from the side wall of the movable tube and the liquid outlet to be misaligned, completely blocking the liquid outlet hole on the side close to the drill rod drive component, leaving only the liquid outlet hole closest to the drill bit to flow out water. When drilling, the ground can be moistened by water, thereby reducing the hardness of the ground and improving the drilling efficiency. This avoids the problem that the hollow drill rod is difficult to drill and prone to damage due to the high hardness of the soil at the roots of street trees. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0027] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0028] Floating roots refer to a situation where the roots of trees grow upward to obtain nutrients or breathe due to improper fertilization or soil compaction, resulting in shallow roots.

[0029] Reference Figure 1-Figure 3 , Figure 1 This is a schematic diagram of the structure of the utility model; Figure 2 For this utility model Figure 1 A schematic diagram of the structure at center A; Figure 3 The present invention is a schematic diagram of a movable pipe structure. An insertable maintenance device includes an insertion assembly 1 and a liquid supply assembly 2. The insertion assembly 1 includes a drill rod driver 11 and a drill rod member 12. The drill rod member 12 is detachably connected to the driving end of the drill rod driver 11. The drill rod driver 11 drives the drill rod member 12 to rotate and drill holes in the ground. A hollow cavity 121 is defined in the middle of the drill rod member 12. Liquid outlets 122 are defined on the circumferential side of the drill rod member 12, connecting the hollow cavity 121 with the outside world. At least one liquid outlet 122 is defined at one end of the drill rod member 12 away from the drill rod driver 11. The liquid supply assembly 2 is disposed on one side of the drill rod driver 11 and supplies liquid into the hollow cavity 121.

[0030] The insertable maintenance device is provided with a drill rod 12 having a hollow cavity 121 and a liquid outlet 122. When it is necessary to inject maintenance liquid into the street trees, the drill rod driving member 11 can be used to drive the drill rod 12 to rotate, thereby extending the drill rod 12 to a specified length. Then, maintenance liquid can be provided into the hollow cavity 121 of the drill rod 12 through the liquid supply component 2, so that the maintenance liquid can flow out through the liquid outlet 122 and directly provide nutrients to the deeper parts of the street trees, so that the roots of the street trees can grow downward, avoiding the problem that traditional watering and fertilizing methods easily cause the roots of the street trees to float up, resulting in damage to the road surface and easy blowing down in windy weather, posing a safety hazard.

[0031] Through the principle of liquid injection, the maintenance liquid is directly injected into the deep roots of street trees to solve the problem that shallow fertilization will cause the roots of street trees to float up. The injection holes left on the ground can serve as temporary air vents to promote the breathing of street tree roots and the infiltration of rainwater, further allowing the roots of street trees to grow deeper.

[0032] Preferably, there are three liquid outlet holes 122 at a height, and they are arranged at equal distances along the central axis of the drill rod 12, so that after the maintenance device is inserted into place, liquid can be injected into the ground under the tree from three different depths at the same time through the three liquid outlet holes 122 at different heights, thereby realizing layered maintenance and further improving maintenance efficiency.

[0033] Preferably, there are four liquid outlet holes 122 at the same height, and they are arranged at equal angles along the circumference of the drill rod 12, so that after the maintenance device is inserted into place, no matter which direction the drill rod 12 is rotated to, liquid can be injected into the side close to the street tree.

[0034] Furthermore, the drill rod 12 is fixedly connected to a filter screen 123 located in the middle of the liquid outlet hole 122. By setting the filter screen 123, when the drill rod 12 is drilling, not much soil will extend into the hollow cavity 121 from the liquid outlet hole 122, causing the hollow cavity 121 and the liquid outlet hole 122 to be blocked, thereby affecting the normal liquid injection of the maintenance device.

[0035] Reference Figure 3-Figure 4 , Figure 4 The figure is a schematic diagram of the structure of the drill rod assembly of the present invention. The insertion assembly 1 also includes a movable tube 13, which is movably sleeved within the hollow cavity 121 and can move along the direction of the hollow cavity 121. The movable tube 13 is provided with a connecting hole 131 located opposite the liquid outlet 122. In the normal state, the liquid outlet 122 and the connecting hole 131 are directly opposite each other, and the curing liquid injected into the hollow cavity 121 can be discharged outward through the connecting hole 131 and the liquid outlet 122. After the movable tube 13 moves relative to the hollow cavity 121, the liquid outlet 122 near one end of the drill rod driver 11 is offset and blocked by the connecting hole 131, leaving only the connecting hole 131 and the liquid outlet 122 farthest from the drill rod driver 11 still connected to the outside world. The end of the movable tube 13 away from the drill rod driver 11 is fixedly connected to a drill bit 132, and the drill bit 132 is located outside the hollow cavity 121.

[0036] Reference Figure 5 , Figure 5 This is another schematic diagram of the movable tube structure of the present invention. A clamping block 133 is fixedly connected to the outer circumference of the movable tube 13. The clamping block 133 limits the movable tube 13's movement path and distance. The limited movement path is along the axial direction of the drill rod 12, and the maximum movement distance is the distance that the liquid outlet 122 and the communication hole 131 at the same height are completely opposite and completely offset.

[0037] Specifically, the connecting hole 131 farthest from the drill rod driving component 11 is oval in shape, so that when the movable tube 13 moves, within the range of the movable tube 13 limited by the blocking block 133, the connecting hole 131 farthest from the drill rod driving component 11 and the liquid outlet 122 are both in a connected state.

[0038] The insertion assembly 1 also includes an elastic member 14, which is arranged between the top wall of the hollow cavity 121 and the movable tube 13, and is connected to the two at both ends. When the drill bit 132 is subjected to pressure, the movable tube 13 overcomes the elastic force of the elastic member 14 and moves axially along the drill rod 12, causing the liquid outlet 122 and the connecting hole 131 to be misaligned. After the pressure on the drill bit 132 disappears, the movable tube 13 can be automatically reset under the action of the elastic member 14, so that all the connecting holes 131 and the liquid outlet holes 122 can be opposite to each other.

[0039] The insert-type maintenance device adds a movable tube 13 and an elastic member 14 in the drill rod 12, so that when drilling through the drill rod 12, the movable tube 13 can overcome the elastic force of the elastic member 14 and shrink inward under the action of pressure at the drill bit 132, so that the connecting hole 131 starting from the side wall of the movable tube 13 and the liquid outlet 122 are misaligned, and the liquid outlet holes on the side close to the drill rod driving member 11 are completely blocked, leaving only the liquid outlet 122 closest to the drill bit 132 to flow out water, so that when drilling, the ground can be moistened by water, thereby reducing the hardness of the ground, improving the drilling efficiency, and avoiding the problem that the hollow drill rod 12 is difficult to drill and prone to damage due to the high hardness of the soil at the roots of street trees.

[0040] The liquid supply assembly 2 includes a liquid storage tank 21 and a liquid delivery pipe 22. The liquid storage tank 21 is arranged on one side of the drill rod driving component 11. The liquid delivery pipe 22 is arranged between the liquid storage tank 21 and the hollow cavity 121, and delivers the curing liquid in the liquid storage tank 21 to the hollow cavity 121.

[0041] The liquid supply assembly 2 also includes a liquid supply drive 23, which is fixedly installed at one end of the liquid storage tank 21. The driving end of the liquid supply drive 23 is connected to one end of the infusion tube 22, and the curing liquid in the liquid storage tank 21 is transported to the hollow cavity 121 through the infusion tube 22.

[0042] An insertable maintenance device further includes a coiled tube assembly 3 , which is disposed on one side of the infusion tube 22 and accommodates and supports the infusion tube 22 .
