Technical Field
[0001] This invention belongs to the field of agricultural implements technology, specifically relating to a device for digging holes in the soil. Background Technology
[0002] During the transplanting process of seedlings cultivated in nurseries, holes need to be dug in the ground. This is usually done manually, which is laborious and time-consuming. Therefore, people often use hole-digging devices. Chinese patent CN220986583U discloses a rapid hole-digging device for seedling planting. When in use, the motor is started, which drives the connecting rod to rotate. The rotation of the connecting rod drives the locking block to rotate, which in turn drives the transmission rod and the rotating drum to rotate, thereby driving the spiral blade to dig holes in the ground. However, its structure is relatively complex, and the motor requires a power source, resulting in high costs. Summary of the Invention
[0003] In view of the problems mentioned in the background art, the present invention provides a device for digging holes in the soil. The device is easy to manufacture and low in cost, can be operated by a single person, and is suitable for small-scale seedling transplanting operations.

[0005] Furthermore, it also includes a pedal 4 mounted on the lower part of the handle 3.
[0006] Preferably, it also includes a pair of retaining rings 5 clamped on the upper and lower sides of the pedal 4, and there is a gap between the pedal 4 and the retaining rings 5; and the pedal 4 can be rotatably fitted into the lower part of the handle 3; the pair of retaining rings 5 are fixed to the handle 3 by pins.
[0007] Furthermore, the digging hook 2 includes four or more, and an even number of, digging hooks 2 with the same structure.
[0008] Preferably, the digging hook 2 includes a first digging hook 21, a second digging hook 22, a third digging hook 23 and a fourth digging hook 24 arranged sequentially at a 90° angle; the projected arc length of the first digging hook 21 is half a circular arc, and the second digging hook 22, the third digging hook 23 and the fourth digging hook 24 have the same structure as the first digging hook 21.
[0009] Furthermore, the fixed base 1 has a screw hole in the middle, and the end of the handle 3 connected to the fixed base 1 has a thread that matches the screw hole in the middle of the fixed base 1.
[0010] Furthermore, the handle 3 includes a vertical handle 31 and a grip 32; one end of the vertical handle 31 is a threaded end, and the other end is connected to the grip 32.
[0011] Beneficial effects: This device for digging holes in the ground has a simple structure, is easy to manufacture, and is relatively convenient to use. It does not require an external power supply and is suitable for digging holes in the ground during the transplanting of seedlings such as potato seedlings and related seedlings. When digging holes in the ground, hold the handle 3, keeping the digging hooks 2 as vertical as possible to the ground, press down and turn the handle 3 clockwise. The sharp points of the multiple digging hooks 2 will enter the ground. When the fixed base 1 contacts the ground, lift the handle 3 upwards. The soil surrounded by the multiple digging hooks 2 will be brought out of the ground, thus forming the required hole in the ground. Attached Figure Description

[0018] The following will refer to the appendices in the embodiments of the present invention. Figure 1-4 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0019] Example 1: A device for digging holes in the soil includes multiple digging hooks 2, a fixed base 1, and a handle 3; the fixed base 1 is disc-shaped, and the handle 3 is connected to its upper part; one end of the digging hook 2 is fixed to the lower edge of the fixed base 1, and is in a downward arc shape, while the other end is sharp and is evenly distributed around the fixed base 1.
[0020] During seedling transplantation, agricultural workers can use this device for digging holes in the ground. By firmly grasping the handle 3 and keeping the digging hooks 2 perpendicular to the ground, pressing down and rotating the handle 3 clockwise, the sharp points of the multiple digging hooks 2 first enter the ground. When the fixed base 1 contacts the ground, lifting the handle 3 upwards pulls the soil surrounded by the multiple digging hooks 2 out of the ground, thus forming the hole needed for seedling transplantation. Depending on the softness of the soil, the above operation can be repeated to dig suitable holes for seedling transplantation. The inventors found that this device facilitates the digging of holes required for potato seedling transplantation, saving labor; it is suitable for digging holes for potato seedling transplantation in small-scale planting; the device is simple to manufacture, inexpensive, and more efficient than other auxiliary tools.
[0021] Example 2: To further reduce the effort required by agricultural workers during the digging process, the device for digging holes in the soil also includes a pedal 4 installed on the lower part of the handle 3. During the digging process, agricultural workers can use the pedal 4 and their feet to apply force, enabling them to work on relatively hard ground, thereby reducing the effort required from their hands.
[0022] Another structure of the device for digging holes in the soil includes a pair of retaining rings 5 clamped on the upper and lower surfaces of the pedal 4, with a gap between the pedal 4 and the retaining rings 5; the pedal 4 can be rotatably fitted into the lower part of the handle 3; the pair of retaining rings 5 are fixed to the handle 3 by pins. During use, because there is a gap between the contact surfaces of the pedal 4 and the retaining rings 5, the pedal 4 can rotate with the handle 3 as the axis. Therefore, agricultural workers can reliably grasp the handle 3, keep the digging hooks 2 perpendicular to the ground as much as possible, press down and rotate the handle 3 clockwise, and at the same time, use their feet to assist in pressing down through the pedal 4. The sharp parts of the multiple digging hooks 2 first enter the ground. When the fixed base 1 contacts the ground, the handle 3 is lifted upwards, and the soil surrounded by the multiple digging hooks 2 is brought out of the ground, thus forming the hole required for transplanting seedlings.
[0023] Example 3: As a specific structure of the above embodiment, the digging hook 2 includes a first digging hook 21, a second digging hook 22, a third digging hook 23, and a fourth digging hook 24 arranged sequentially at a 90° angle; wherein the projected arc length of the first digging hook 21 is half an arc (see appendix for bottom view). Figure 4The second digging hook 22, the third digging hook 23 and the fourth digging hook 24 have the same structure as the first digging hook 21.
[0024] The symmetrical arrangement of the first digging hook 21, the second digging hook 22, the third digging hook 23 and the fourth digging hook 24 provides good soil encirclement. The soil blocks in the four trenches have a good force-bearing surface, so that the soil encircled within can be smoothly brought out of the ground when the handle is lifted in stage 3.
[0025] Correspondingly, four or more digging hooks 2 can be set, and an even number of digging hooks 2 with the same structure can be set to enhance the reliable removal of the surrounding soil.
[0026] The fixing base 1 has a screw hole in the middle, and the end of the handle 3 that connects to the fixing base 1 has a thread that matches the screw hole in the middle of the fixing base 1. The threaded connection structure enables detachment, making it convenient to carry and install.
[0027] The handle 3 includes a vertical handle 31 and a grip 32; one end of the vertical handle 31 is threaded, and the other end is connected to the grip 32. The grip increases the downward pressure during the drilling process and improves operability.
[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
