Description

Technical Field

[0001] This utility model belongs to the technical field of hole-opening devices, and in particular relates to a hole-opening device for seedling planting. Background Technology

[0002] In the transplanting of seedlings of medicinal herbs such as angelica, planting holes is a crucial step. Traditionally, this is done manually, which is not only inefficient and labor-intensive, but also makes it difficult to ensure the consistency and accuracy of the holes, thus affecting the growth and survival rate of the angelica seedlings. Because angelica has high requirements for soil and growing environment, the quality and depth of the planting holes are vital to its growth. Improper planting methods may damage the root system, affecting its ability to absorb nutrients and water, ultimately impacting the yield and quality of the medicinal herb.

[0003] Although some hole-opening devices exist on the market, these devices often suffer from problems such as complex structure, cumbersome operation, and high cost, making it difficult to meet the actual needs of transplanting angelica seedlings. Especially in some cases of mulched planting, traditional hole-opening methods can easily cause significant traction on the film, leading to film damage or misalignment. This not only affects the soil's heat retention and moisture retention but may also promote weed growth and pest and disease invasion, further impacting the growth and yield of angelica.

[0004] Therefore, there is an urgent need for a seedling planting hole-opening device that is simple in structure, easy to operate, highly efficient, and can ensure the quality and consistency of hole opening. Utility Model Content

[0005] The purpose of this utility model is to provide a hole-opening device for seedling planting. By combining a hole-opening rod with a driving device, along with the design of a cross-shaped cone and spiral auger blades, and the assistance of a splash guard, it solves the problems of low hole-opening efficiency, high labor intensity, inconsistent hole-opening quality, and easy damage to the film during mulching planting in the existing Angelica seedling transplanting process.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a hole-opening device for seedling planting, including a hole-opening rod and a driving device for clamping and driving the hole-opening rod; the hole-opening rod includes a cylindrical rod body; a coaxially arranged cross cone is fixed to the lower end of the cylindrical rod body; a spiral auger blade is fixed to the outer wall of the connection end between the cylindrical rod body and the cross cone.

[0008] As a preferred embodiment of this utility model, a ring of anti-slip grooves is formed on the outer wall of the upper end of the cylindrical rod.

[0009] As a preferred technical solution of this utility model, it also includes a splash guard; the outer wall of the cylindrical rod is fixed with a limiting ring plate above the spiral auger blade.

[0010] As a preferred embodiment of this utility model, the splash guard includes a conical cover that is larger at the bottom and smaller at the top; a metal ring is fixed inside the upper end of the conical cover; the inner diameter of the metal ring is larger than the diameter of the cylindrical rod; and the outer diameter of the metal ring is larger than the outer diameter of the limiting ring plate.

[0011] As a preferred embodiment of this utility model, the driving device is a hand drill.

[0012] This utility model has the following beneficial effects:

[0013] This invention uses a hand drill to drive the hole-opening rod to rotate at high speed. By utilizing the synergistic effect of the cross-shaped cone and the spiral auger blades, holes for planting angelica can be quickly opened on the planting ridges, significantly improving the efficiency of hole opening.

[0014] This invention utilizes a cross-shaped cone design to allow for rapid penetration through the film while minimizing the pulling on the film. This avoids large-area damage to the film caused by opening holes, helps protect soil moisture and temperature, and promotes the growth of Angelica sinensis.

[0015] The use of this splash guard effectively controls the upward-thrown soil, causing it to scatter around the excavated hole. This avoids soil waste, facilitates subsequent backfilling, and ensures the rational use of soil.

[0016] This invention features a simple structure, with compact and robust connections between components, making it easy to operate and maintain, thus reducing operating costs. Furthermore, its design considers convenience and durability in practical use, ensuring long-term stability and reliability.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[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 scope of protection of the present utility model. Specific Implementation Example 1:

[0026] Please see Figure 1-3 As shown, this utility model is a hole-opening device for seedling planting, including a hole-opening rod 1 and a driving device for clamping and driving the hole-opening rod 1. The hole-opening rod 1 includes a cylindrical rod body 11. A coaxially arranged cross-shaped cone 12 is fixed to the lower end of the cylindrical rod body 11. A spiral auger blade 13 is fixed to the outer wall of the connection end between the cylindrical rod body 11 and the cross-shaped cone 12. The driving device is a hand drill (not shown in the figure).

[0027] In order to improve the relative static friction of the electric drill clamping the hole-opening rod 1, a ring of anti-slip groove 14 is opened on the outer wall of the upper end of the cylindrical rod 11.

[0028] This system also includes a splash guard 2. A limiting ring plate 15 is fixed to the outer wall of the cylindrical rod 11 above the auger blades 13. The splash guard 2 includes a conical cover 21 that is wider at the bottom and narrower at the top. A metal ring 22 is fixed inside the upper end of the conical cover 21. The inner diameter of the metal ring 22 is larger than the diameter of the cylindrical rod 11. The outer diameter of the metal ring 22 is larger than the outer diameter of the limiting ring plate 15. When the drill clamps the drilling rod 1 and rotates at high speed, the splash guard 2 does not rotate with the drilling rod 1. The metal ring 22 slides and rubs against the limiting ring plate 15 or the cylindrical rod 11. This design of the metal ring 22 helps to extend the service life of the splash guard 2.

[0029] The process of using the hole-opening device for seedling planting is as follows: First, the upper end of the cylindrical rod 11 of the hole-opening rod 1 is clamped and mounted on an electric drill. The cross-shaped cone 12, as the leading component, uses its sharp shape to quickly penetrate the film covering the planting ridge for planting angelica. During this process, the cross-shaped cone 12 exerts minimal strain on the film, avoiding large-area damage to the film caused by hole opening. Then, the electric drill is started, causing the hole-opening rod 1 to rotate at high speed. As the electric drill continues to operate, the auger blades 13 begin to function. The centrifugal force generated by its rotation quickly transports the soil upwards to the top of the film, while gradually forming a hole on the ridge for planting angelica. In this process, the design of the auger blades 13 not only improves the hole-opening efficiency but also ensures the regular shape of the hole, which is beneficial for the subsequent transplanting and growth of angelica seedlings.

[0030] While the holes are being dug, the splash guard 2 plays a crucial role. It effectively controls the soil thrown upwards by the rotating auger blades 13, causing the soil to scatter around the dug holes. This avoids soil waste and facilitates the backfilling work after the angelica seedlings are transplanted into the dug holes.
