Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, and in particular to a portable geological exploration drilling device. Background Technology

[0002] Miniaturized drilling equipment features a simplified design, making it easy to carry and highly flexible. It is an essential tool for obtaining soil and rock samples and probing geological structures, playing an irreplaceable role, especially in exploration tasks with complex terrain. Currently, commonly used miniaturized drilling equipment typically consists of a main unit and a guide support. Lifting the main unit often relies on manual labor, making operation quite strenuous. While some models incorporate large-diameter turntables and lifting chains, which reduce operational intensity to some extent, this significantly increases the equipment's size and weight, severely compromising portability. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides a portable geological exploration drilling tool to solve the technical problem that the lifting of the main unit of existing small geological exploration drilling tools relies on manual labor, resulting in high labor intensity.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution:

An output wheel is fitted onto the power shaft, and the two are connected via a one-way transmission mechanism. The output wheel is also connected to the lifting gear. When the power shaft rotates in the forward direction, it does not transmit power to the output wheel. When the power shaft rotates in the reverse direction, it drives the output wheel to rotate synchronously via the one-way transmission mechanism. The lifting gear is driven by the output wheel to roll upwards along the rack, thereby achieving automatic lifting of the main unit.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] See Figures 1 to 4 As shown in the embodiment, the detailed structure of the portable geological exploration drill of this utility model is disclosed. The portable geological exploration drill includes a main unit 8, a base 1, and a guide column 2. The lower end of the main unit 8 is provided with a vertically downward extending power shaft 6, and a drill rod seat 5 is fixed at the lower end of the power shaft 6 for connecting the drill rod. The guide column 2 extends in the vertical direction, and its lower end is fixedly connected to the base 1. A guide sleeve 10 is fitted on the guide column 2 and slides with it. The main unit 8 is fixedly connected to the guide sleeve 10, so that the main unit 8 can move up and down along the guide column 2.

[0023] A vertically extending groove 3 is provided on the side wall of the guide post 2, and equidistant teeth are provided at the bottom of the groove 3, thereby forming a rack portion 4 extending in the vertical direction; a lifting gear 13 is rotatably connected to the guide sleeve 10, and the lifting gear 13 meshes with the rack portion 4 to form a gear and rack transmission pair, so that when the lifting gear 13 rotates, it rolls along the rack portion 4, thereby driving the guide sleeve 10 to move vertically along the guide post 2;

[0024] The main unit 8 can output power in two directions, namely, the power shaft 6 can rotate in both the forward and reverse directions. An output wheel 17 is sleeved on the power shaft 6. The power shaft 6 and the output wheel 17 are connected by a one-way transmission mechanism 18. The output wheel 17 is located on the upper side of the drill rod seat 5 and is connected by a transmission mechanism 13. Based on the one-way transmission characteristic of the one-way transmission mechanism 18, when the power shaft 6 rotates in the forward direction, it does not transmit power to the output wheel 17. At this time, the output wheel 17 and the lifting gear 13 are in a free state and will not prevent the main unit 8 from moving downward. The power shaft 6 drives the drill rod to rotate and perform normal drilling work. When the power shaft 6 rotates in the reverse direction, it drives the output wheel 17 to rotate synchronously through the one-way transmission mechanism 18. The lifting gear 13 is driven by the output wheel 17 to roll upward along the rack part 4, which drives the guide sleeve 10 to move upward, realizing the automatic lifting of the main unit 8.

[0025] Therefore, during use, the power transmission direction of the main unit 8 can be adjusted as needed. Normal drilling work is carried out by rotating the power shaft 6 in the forward direction, and the main unit 8 is automatically lifted by rotating the power shaft 6 in the reverse direction, saving labor costs and improving work efficiency. When the main unit 8 stops running, the power shaft 6 cannot rotate due to the self-locking effect of the power source, so the output wheel 17 and the lifting gear 13 also cannot rotate, thus keeping the main unit 8 at the adjusted height.

[0026] See Figure 1 , Figure 2 As shown, in a specific implementation, the guide post 2 adopts a cylindrical design, and correspondingly, the guide sleeve 10 adopts a cylindrical design, thereby improving the fit between the guide post 2 and the guide sleeve 10 and reducing the process difficulty during implementation. Since the rack part 4 is set in the groove 3 on one side of the guide post 2, it will not affect the sliding fit between the guide sleeve 10 and the guide post 2. At the same time, during the process of the lifting gear 13 engaging with the rack part 4, the engagement of the lifting gear 13 with the groove 3 can achieve a positioning function, thus eliminating the need for an additional positioning mechanism between the guide post 2 and the guide sleeve 10 to prevent relative rotation, making the overall structure of this portable geological exploration drill simpler and more compact.

[0027] See Figure 4 As shown, in a specific implementation, the output wheel 17 is mounted on the power shaft 6 and the two are connected by a one-way transmission mechanism 18. The one-way transmission mechanism 18, which is set between the rotating mating parts, is very common in the prior art. For example, one-way bearings and ratchet pawl mechanisms are commonly used one-way transmission mechanisms. Specifically, the mating method between the output wheel 17 and the power shaft 6 can be implemented by referring to the transmission structure in ratchet wrenches and bicycle flywheels.

[0028] In specific implementation schemes, the power source type of the main unit 8 can be selectively configured according to actual needs. Specifically, the main unit 8 can use a motor as its power source, and correspondingly, a power supply component is provided on the base 1 to provide electrical energy to the motor. Furthermore, the motor is preferably a variable frequency motor or other speed-adjustable motor to ensure that the power shaft 6 can rotate forward at a high speed to achieve high efficiency in drilling operations. At the same time, the power shaft 6 can rotate in the reverse direction at a lower speed to reduce the moving speed of the main unit 8 during lifting and improve ease of operation. In addition, the main unit 8 can also use an internal combustion engine as its power source, and a reversing mechanism and a reduction mechanism are set in the transmission system between the internal combustion engine and the power shaft 6 to achieve adjustable steering and speed of the power shaft 6.

[0029] In a specific implementation scheme, since the main unit 8 and the guide sleeve 10 are fixedly connected, their relative positions are fixed, allowing the output wheel 17 and the lifting gear 13 to achieve a stable transmission connection using a conventional transmission structure, and enabling a corresponding deceleration effect during transmission. To ensure the simplicity and compactness of the structure of this portable geological exploration drill, the preferred implementation of the transmission structure between the output wheel 17 and the lifting gear 13 is as follows:

[0030] like Figure 4 As shown, a synchronous gear 19 is fixed on the axle 14 of the lifting gear 13. The synchronous gear 19 and the output wheel 17 are both bevel gears and mesh with each other.

[0031] Furthermore, a gearbox 7 is fixed to the lower end of the main unit 8, and the synchronous gear 19 and the output wheel 17 are located inside the gearbox 7; the lower end of the gearbox 7 is provided with a first bushing 15 sleeved on the power shaft 6, and the side of the gearbox 7 is provided with a second bushing 16 sleeved on the wheel axle 14 of the lifting gear 13; thus, the gearbox 7 can provide good protection for the mating structure of the synchronous gear 19 and the output wheel 17, and can provide auxiliary support for the power shaft 6 and the wheel axle 14 of the lifting gear 13, thereby improving the mating stability and safety of the above components.

[0032] like Figure 1 , Figure 2 As shown, in a further embodiment, a handrail 9 is fixedly connected to the main unit 8, and the working state of the main unit 8 is regulated by a control device 11, which is fixed to the handrail 9; thus, the operator can conveniently and quickly flexibly regulate the starting and stopping of the main unit 8, the speed and direction of the power shaft 6, and other working states while holding the handrail 9.

[0033] like Figure 2 , Figure 3As shown, in a further embodiment, a gear seat 12 is fixedly connected to the side of the guide sleeve 10, and the lifting gear 13 is rotatably mounted on the gear seat 12.
