Description

Technical Field

[0001] This utility model relates to the field of mangrove seedling planting technology, specifically a spiral soil drilling device for mangrove seedling planting. Background Technology

[0002] In the process of planting mangrove seedlings, it is necessary to dig pits at the planting sites according to the type and growth habits of the seedlings, and then plant the seedlings scientifically.

[0003] In the soil drilling operation for mangrove seedling planting, the electric motor drives the drill bit to rotate at high speed and apply downward pressure when the drilling machine is running. This generates significant vibration and reaction force, causing the drilling machine to shake during operation. This not only affects the operator's work experience, increases the difficulty of operation and fatigue, but may also cause the drilling machine to shift as a whole, making it impossible to drill accurately at the predetermined position and reducing work efficiency. To address these issues, we have proposed a spiral soil drilling device for mangrove seedling planting. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a spiral soil drilling device for planting mangrove seedlings, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a spiral soil drilling device for planting mangrove seedlings, including a soil drilling machine, a support mechanism and a leveling mechanism;

[0006] The drilling machine includes a base plate, a motor, a drill bit, and a handle. The motor is fixed to the top surface of the base plate via a square flange. The output shaft of the motor passes through the central hole of the base plate and is fixedly connected to the drill bit. The handle is integrally formed on the front and rear sides of the base plate.

[0007] The support mechanism includes a base plate, guide posts, locking bolts, extension arms, and stops. Extension arms are fixedly connected to the left and right sides of the base plate. The extension arms are slidably connected to the guide posts fixed to the top surface of the base plate. A stop is provided at the top of the guide posts. Threaded holes are provided inside the extension arms and guide posts. The locking bolts can be screwed into the threaded holes.

[0008] The leveling mechanism includes a main screw, a circular base, a secondary screw, a pressure reducing plate, and a reinforcing ring. Both the main screw and the secondary screw are threaded to the base plate. The lower end of the main screw is connected to the circular base, and the lower end of the secondary screw is connected to the pressure reducing plate. The surface of the circular base is provided with a reinforcing ring.

[0010] Preferably, there are two guide posts, located on the left and right sides of the top surface of the base plate, and the two guide posts are arranged in parallel.

[0011] Preferably, the number of leveling mechanisms is four, which are respectively set at the four corners of the base plate.

[0024] 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.

[0025] Please see Figure 1-5 A spiral soil-drilling device for planting mangrove seedlings includes a soil drill, a support mechanism 5, and a leveling mechanism 6. The soil drill includes a base plate 1, a motor 2, a drill bit 3, and a handle 4. The motor 2 is fixed to the top surface of the base plate 1 by a square flange. The output shaft of the motor 2 passes through the central hole of the base plate 1 and is fixedly connected to the drill bit 3. The handle 4 is integrally formed on the front and rear sides of the base plate 1. The drill bit 3 is provided with spiral blades. The spiral blades are triangular blades with a local thickening on the outer edge. The handle 4 has a U-shaped structure design, and the surface of the handle 4 is also provided with anti-slip, which makes it convenient for users to hold with both hands, providing a comfortable operating posture and reducing operator fatigue.

[0026] The support mechanism 5 includes a base plate 51, guide posts 52, locking bolts 53, extension arms 54, and stop blocks 55. Extension arms 54 are fixedly connected to the left and right sides of the base plate 1. The extension arms 54 are slidably connected to the guide posts 52 fixed to the top surface of the base plate 51. The top of the guide post 52 is provided with a stop block 55 to limit the upward sliding of the base plate 51 and prevent the base plate 51 from slipping off the guide post 52 during transportation or operation, thus ensuring the safety and stability of the device. The extension arms 54 and the guide posts 52 are provided with threaded holes, and the locking bolts 53 can be screwed into the threaded holes. There are two guide posts 52, located on the left and right sides of the top surface of the base plate 51, and the two guide posts 52 are arranged in parallel. The head of the locking bolt 53 is provided with a knob, and the outer surface of the knob is provided with anti-slip texture, which makes it convenient for the user to apply force when rotating the locking bolt 53, thus improving the ease of operation.

[0027] The leveling mechanism 6 includes a main screw 61, a circular base 62, a secondary screw 63, a pressure-reducing plate 64, and a reinforcing ring 65. Both the main screw 61 and the secondary screw 63 are threadedly connected to the base plate 51. The lower end of the main screw 61 is connected to the circular base 62, and the lower end of the secondary screw 63 is connected to the pressure-reducing plate 64. The circular base 62 is provided with a reinforcing ring 65. There are four leveling mechanisms 6, which are respectively set at the four corners of the base plate 51. The diameter of the pressure-reducing plate 64 is larger than the diameter of the secondary screw 63, and the pressure-reducing plate 64 can abut against the reinforcing ring 65, which increases the contact area with the reinforcing ring 65, can better disperse pressure, reduce local stress concentration, improve the service life of the pressure-reducing plate 64 and the reinforcing ring 65, and also ensure the uniform transmission of support force.

[0028] Working principle: A square flange is used to fix the motor 2 to the top surface of the base plate 1. The output shaft of the motor 2 passes through the central hole of the base plate 1 and is fixedly connected to the drill bit 3. Handles 4 are integrally formed on both the front and rear sides of the base plate 1, forming a soil drill. Therefore, when the user holds the handle 4 and starts the motor 2, it drives the drill bit 3 to rotate, pressing down on the entire machine body. The spiral blades of the drill bit 3 bring out soil, forming suitable planting pits. After the mangrove seedlings are planted, the soil brought out is directly used for backfilling. In the support mechanism 5, extension arms 54 are fixedly connected to the left and right sides of the base plate 1. The extension arms 54 and the guide posts 52 fixed to the top surface of the base plate 51 are in a sliding connection relationship. While providing support to the soil drill, the guide posts 52 also restrict the sliding direction of the soil drill. During transportation, after sliding the base plate 1 up to contact the stop block 55 at the top of the guide post 52, the locking bolt 53 is screwed into the threaded holes inside the extension arm 54 and the guide post 52 in sequence to prevent the drill bit 3 from being damaged by impact during transportation. A leveling mechanism 6 is provided at each of the four corners of the base plate 51. The main screw 61 and the auxiliary screw 63 are threaded to the base plate 51. Therefore, by rotating the main screw 61, the distance between each circular foot 62 and the base plate 51 can be adjusted to meet the support requirements of uneven terrain. When the circular foot 62 is adjusted to the appropriate position, the auxiliary screw 63 is rotated so that the pressure relief plate 64 at the lower end of the auxiliary screw 63 abuts against the reinforcing ring 65 on the surface of the circular foot 62, providing additional support force and ensuring the support effect provided by the leveling mechanism 6.
