Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary tools for planting white tea, and in particular to an auxiliary device for drilling holes for planting white tea under chestnut forests. Background Technology

[0002] Chinese patent CN115250824A discloses a planting method for intercropping white tea with chestnut trees. When planting white tea under the canopy of chestnut trees, the location of the planting hole is crucial because the root system of chestnut trees is complex and difficult to determine directly. Therefore, when digging the planting hole for white tea, it is easy to dig into the roots of chestnut trees, resulting in wasted time. Therefore, how to predict whether there are chestnut tree roots at the digging point before digging, so as to dig the hole and plant white tea in a position that avoids the chestnut tree roots, has become an urgent technical problem to be solved. Utility Model Content

[0028] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0029] Please refer to Figure 1 as well as Figure 2 A hole-drilling auxiliary device for planting white tea under chestnut forests includes:

[0030] The base 1 is provided with a plurality of clearance holes 11 arranged in a circumferential array;

[0031] Connecting rod 2, the lower end of which is connected to base 1;

[0032] The transmission connecting seat 3 is connected to the upper end of the connecting rod 2. The transmission connecting seat 3 is provided with a first gear 311 located in the middle and a plurality of second gears 312 that are planetarily distributed and mesh with the first gear 311. The central shaft of the second gear 312 is provided with a threaded hole. The transmission connecting seat 3 is provided with a plurality of limiting through holes coaxial with the threaded holes. The inner wall of the limiting through holes is provided with a flat key 321.

[0033] The thread test rod 4 is threadedly connected to the threaded hole. The side of the thread test rod 4 is provided with a linear keyway 41. The flat key 321 is limited and fitted in the linear keyway 41. Each thread test rod 4 is located directly above each clearance hole 11. The lower end of the thread test rod 4 is a pointed end 42.

[0034] The driving component 5 is connected to the transmission connection seat 3 and is used to drive the first gear 311 to rotate.

[0035] In the above embodiments, during use, the base 1 of the device is placed under a chestnut forest at the target location for drilling. After the user positions the device by stepping on the base 1, the first gear 311 is rotated by controlling the drive component 5, which in turn drives multiple second gears 312 to rotate synchronously. Since the threaded test rod 4 is threadedly engaged with the threaded hole on the inner side of the second gear 312, and the linear keyway 41 and the flat key 321 of the limiting through hole on the side of the threaded test rod 4 restrict the rotation of the threaded test rod 4 through the flat key 321, the rotation of the second gear 312 causes the threaded test rod 4 to move downward along its axial direction, so that the pointed end 42 of the threaded test rod 4 is inserted into the soil. In the soil, because the hardness of the chestnut tree roots is greater than that of the soil, when the threaded test rod 4 encounters a large resistance with non-linear changes during its descent, it is determined that the lower end of one of the threaded test rods 4 has touched the tree root. At this time, the depth of the tree root can be determined by measuring the depth of the threaded test rod 4 inserted into the soil. If the depth does not reach the required depth for drilling, it means that the location is not a suitable location for drilling under the forest, and the above method needs to be tested on other locations. Through the above test, compared with the method of directly drilling holes, on the one hand, the manpower consumed by ineffective drilling is reduced, and on the other hand, excessive damage to the soil layer under the chestnut tree caused by too many ineffective drillings is avoided.

[0036] In a preferred embodiment, the base 1 is a rhomboid plate, and the upper part of the two acute angles of the rhombus is provided with an anti-slip part 12 for stepping.

[0037] In the above embodiments, refer to Figure 1 The diamond-shaped base 1 and the anti-slip part 12 make it easy for the operator to step on the base 1 with both feet to limit the movement and prevent the device from tilting or tipping over due to the reaction force generated during the descent of the thread test rod 4.

[0038] In a preferred embodiment, the angle between the linear keyway 41 and the axial direction of the threaded test rod 4 is 0-15 degrees.

[0039] In a preferred embodiment, the angle between the linear keyway 41 and the axial direction of the threaded test rod 4 is 10-15 degrees.

[0040] In the above embodiments, when the angle between the linear keyway 41 and the thread test rod 4 is greater than 0 degrees, the corresponding linear keyway should also adapt to the corresponding angle, so that the thread test rod 4 rotates at a certain angle during the descent, making it easier for the thread test rod 4 to penetrate into the soil.

[0041] In a preferred embodiment, the transmission connection seat 3 includes a flat plate 31 and a plurality of limiting sleeves 32 arranged in an array and connected to the lower part of the flat plate 31. The limiting through hole passes through the flat plate 31 and the limiting sleeves 32. The first gear 311 is rotatably connected to the upper part of the flat plate 31 through a bearing, and the second gear 312 is rotatably connected to the upper part of the flat plate 31 through a bearing.

[0042] In the above embodiments, by setting the limiting sleeve 32, the spiral test rod is better radially limited during downward movement, ensuring the smooth downward movement of the spiral test rod.

[0043] In a preferred embodiment, the driving component 5 includes a third gear, a fourth gear, and a driving hand crank 53. The third gear is rotatably connected to the upper part of the plate 31 via a bearing and meshes with the first gear 311. The fourth gear is rotatably connected to the upper part of the plate 31 via a bearing and meshes with the third gear. The hand crank 53 is connected to the fourth gear for driving the fourth gear to rotate.

[0044] In the above embodiments, the rotation of the hand crank 53 drives the fourth gear to rotate, thereby achieving the purpose of controlling the axial displacement of the spiral test rod through the meshing transmission of the third gear, the first gear 311, and the second gear 312.

[0045] In a preferred embodiment, the upper part of the transmission connecting seat 3 is connected to the "door"-shaped carrying handle 6. This makes it convenient for the user to carry and for the device to be transported.

[0046] In the above embodiments, it should be noted that after each control of the spiral test rod to be driven down for testing, the device is pulled up directly through the handle 6, and then the thread groove and linear keyway 41 of the spiral test rod are cleaned with water. Then, the lower end of the spiral test rod is retracted to the top of the base 1 by reversing the hand crank 53. Then, the acupoint test is carried out in the next position.

[0047] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
