Description

Technical Field

[0001] This utility model belongs to the field of greening and planting technology, specifically relating to a handheld hole-digging device for greening and planting. Background Technology

[0002] Greening and planting refers to activities that improve the environment by planting plants. It encompasses various aspects such as national land greening, urban greening, roadside greening, and roadside greening. Generally, greening and planting requires digging holes in the planting ground to ensure that the roots of the trees to be planted can be placed inside. In current technology, hole digging is generally done using handheld hole diggers. Handheld hole diggers are portable garden machinery that are widely used in afforestation, orchard planting, farmland construction, and other greening and planting fields. However, some existing handheld hole diggers often have certain shortcomings in use, so they need to be improved.

[0003] Chinese patent CN214676479U discloses a gasoline-powered handheld portable posthole digger, comprising a digger body, a drill bit fixedly mounted at the bottom of the digger body, a storage box fixedly mounted at the front of the digger body, a motor fixedly mounted at the bottom of the storage box, a tray fixedly sleeved at the output end of the motor, a measuring tape wound around the top of the tray, a white powder cylinder fixedly mounted at one end of the measuring tape, and a powder outlet pipe fixedly mounted at the bottom of the white powder cylinder. This gasoline-powered handheld portable posthole digger uses the motor to drive the tray to rotate, facilitating the unwinding or rewinding of the measuring tape. Using the markings on the measuring tape, the white powder cylinder is pulled to a designated distance from the drill bit, compressing the white powder inside the cylinder onto a designated location as a marker, thus controlling the distance between adjacent holes and reducing digging errors.

[0004] However, while the above-mentioned technical solution can achieve the purpose of digging holes for greening and planting, and prevent soil from splashing during digging, the internal retaining cloth is placed vertically downwards. As the drill bit moves downwards, the retaining cloth will continuously descend, causing it to accumulate on the ground and even be pulled into the hole being dug by the drill bit, resulting in damage to the retaining cloth and affecting its use in subsequent digging work. Therefore, it has certain limitations in use. Utility Model Content

[0005] The purpose of this invention is to provide a handheld hole-digging device for greening and planting, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A handheld hole-digging device for greening and planting includes: a hole-digging machine body, handles fixedly connected to both sides of the hole-digging machine body, a placement box fixedly connected to the surface of the hole-digging machine body, an automatic winding box fixedly connected to the surface of the handles, an isolation cloth inside the automatic winding box, a foot pedal fixedly connected to the bottom end of one side of the isolation cloth, a cleaning chamber fixedly connected to one side of the bottom of the automatic winding box, a drive motor fixedly connected to one side of the cleaning chamber, and a cleaning roller fixedly connected to the output end of the drive motor, with the surface of the cleaning roller in contact with the surface of the isolation cloth.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) When planting green plants, the staff can dig holes in the ground through the hole digger body to ensure that the green plants can be planted. At the same time, the soil splashed by the isolation cloth can be blocked during the digging work. As the hole digger body descends, the isolation cloth can be rolled up and cleaned during the rolling up to avoid the accumulation of impurities on its surface and cause jamming after rolling up, which is convenient for subsequent use.

[0014] (2) When the hole digger is working, it can control the distance between the holes according to the number of holes to be dug, so as to ensure that the spacing between the holes is the same, thereby making the spacing between the green plants planted later consistent and improving the aesthetics of the green plants.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] Please see Figures 1 to 4 As shown, a handheld hole-digging device for greening and planting includes a hole-digging machine body 1, with handles 2 fixedly connected to both sides of the hole-digging machine body 1, a placement box 3 fixedly connected to the surface of the hole-digging machine body 1, an automatic winding box 4 fixedly connected to the surface of the handles 2, an isolation cloth 5 inside the automatic winding box 4, a foot pedal 6 fixedly connected to the bottom of one side of the isolation cloth 5, a cleaning chamber 7 fixedly connected to one side of the bottom of the automatic winding box 4, a drive motor 8 fixedly connected to one side of the cleaning chamber 7, and a cleaning roller 9 fixedly connected to the output end of the drive motor 8, with the surface of the cleaning roller 9 in contact with the surface of the isolation cloth 5. The handle 2 allows the operator to use the post hole digger body 1 stably. The automatic rewind box 4 allows the isolation cloth 5 to be pulled out when needed and automatically rewound when not in use. This principle is the same as that of an automatic rewind screen, so it will not be described in detail. The isolation cloth 5 prevents soil from splashing during operation and thus avoids affecting the operator. The cleaning chamber 7 fixes the drive motor 8 and provides a certain driving force for the rotation of the cleaning roller 9. The side of the cleaning chamber 7 facing the isolation cloth 5 has a hollow design, which makes it easy for the cleaning roller 9 to pass through its interior and contact the surface of the isolation cloth 5.

[0023] Example 2:

[0024] Please see Figure 1 and Figure 2As shown, two connecting rods 12 are fixedly connected to the surface of the placement box 3. An arc-shaped positioning plate 13 is fixedly connected to the bottom end of the connecting rods 12, and an arc-shaped support piece 14 is fixedly connected to the surface of the arc-shaped positioning plate 13. The connecting rods 12 fix the arc-shaped positioning plate 13, and the arc-shaped support piece 14 is fixed by the arc-shaped positioning plate 13.

[0025] One end of the measuring tape 10 is fixedly connected to a marking cylinder 15, and the top of the marking cylinder 15 is fixedly connected to a pull ring 16. The marking cylinder 15 is supported and attracted by the arc-shaped support plate 14. Both the marking cylinder 15 and the arc-shaped support plate 14 are made of magnets and attract each other to achieve stability. The pull ring 16 makes it easy to pull the marking cylinder 15 up after it is inserted into the ground.

[0026] The placement box 3 has a measuring tape 10 inside, and one end of the measuring tape 10 is fixedly connected to the surface of the marking tube 15. The surface of the placement box 3 has a slot 11. The measuring tape 10 allows the marking tube 15 to be pulled out to a certain length, making it easier to calculate the distance. This helps staff to better understand the distance between the dug holes and ensures the consistency of the spacing after the green plants are planted. The slot 11 allows the measuring tape 10 to pass through its interior and connect to the surface of the marking tube 15.

[0027] The post hole digger body 1 has a drill rod 17 rotatably mounted inside, and several heat dissipation holes 18 are opened inside the post hole digger body 1. The drill rod 17 is used to drill into the ground to achieve the purpose of digging a hole, and the heat dissipation holes 18 allow outside air to enter the post hole digger body 1 during operation to achieve the purpose of heat dissipation.

[0028] The working principle of this utility model is as follows: The operator moves the post hole digger body 1 to a suitable position beforehand, then pulls out the isolation cloth 5 to make it contact the ground. The operator then presses the foot pedal 6, controlling the post hole digger body 1 to work, causing it to drive the drill rod 17 downwards to drill a hole. While drilling, the isolation cloth 5 blocks splashing soil. As the drilling depth increases, the post hole digger body 1 descends continuously, and the automatic rewind box 4 follows. The isolation cloth 5 is then continuously retracted into the automatic rewind box 4. Simultaneously, the operator controls the drive motor 8 to work, and the output of the drive motor 8 drives the cleaning roller 9 to rotate, thereby... The surface of the retracted isolation cloth 5 is cleaned to ensure its cleanliness and avoid the residue of impurities that could cause the isolation cloth 5 inside the automatic rewind box 4 to jam. After the hole digger body 1 descends to a certain depth, the distance between the marking cylinder 15 and the ground is relatively close. Then, the worker pulls the marking cylinder 15 outward, which in turn pulls the measuring tape 10. While pulling the marking cylinder 15, the worker observes the scale on the measuring tape 10. Once the appropriate distance is reached, the marking cylinder 15 is placed downward and pressed down so that the ground maintains a circular shape with the same shape as the marking cylinder 15. The hole digging work can then be carried out at this location.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
