Description

Technical Field

[0001] The utility model belongs to the technical field of geological exploration and drilling, and in particular relates to an exploration and drilling device. Background Art

[0002] Building roads is beneficial to the input and output of materials and personnel between the local area and the outside world. The construction of roads must comply with national technical standards. Before the construction of roads, geological surveys and drilling are required in order to formulate corresponding construction plans.

[0003] In the prior art, a Chinese patent with publication number CN219470875U discloses a geological detection device for highway survey, including a handle and a shell, the top of the shell is fixedly connected to the handle, the top two sides of the shell are fixedly connected to the fixed block, the inner end of the fixed block is fixedly connected to a circular ring, the inner wall of the circular ring is fixedly connected to the motor, the two sides of the shell are processed with sliding grooves, and the bottom of the shell is provided with a protective device. When the user controls the drill bit to apply pressure to the ground through the handle, the protective cover drives the connecting block to move upward under the influence of the reaction force after the protective cover contacts the ground, the connecting block drives the slider to slide, the connecting block drives the spring to compress, and the shell drives the drill bit downward along the inner wall of the protective cover, and at the same time, the protective cover is always affected by the elastic force of the spring to drive the rubber pad to contact the ground, so that the dust generated by the drill bit and the ground is blocked by the protective cover.

[0004] However, in actual use, since the motor in the above solution is directly connected to the drill bit through a round rod, when the drill bit drills into the ground, the motor not only needs to provide horizontal rotation torque for the drill bit, but also needs to provide vertical abutment force for the drill bit. However, the motor as a driving component has a poor load-bearing capacity, so the vertical abutment force can easily cause damage to the motor, thereby affecting the service life of the device. Utility Model Content

[0005] The utility model aims to provide an exploration drilling device to solve the problem that the motor is easily damaged in the above solution.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a survey drilling device, comprising

[0007] A housing, a protective cover is provided at the lower end of the housing, and a mounting plate is fixed inside the housing;

[0008] The drilling mechanism includes a motor, a driving rod, a driven rod, a drill rod and a ball bearing. The motor is fixed on a mounting plate. A slide groove is provided at the bottom of the mounting plate. The top of the driving rod is fixed to the rotating end of the motor. The bottom of the driving rod extends into the slide groove. A plurality of protrusions are evenly distributed around the rod body of the driving rod. A transmission groove is provided at the top of the driven rod. The driving rod and the protrusions are both slidably plugged into the transmission groove. The ball bearing is installed at the top of the driven rod. The driven rod is slidably matched with the slide groove. The bottom of the driven rod extends into the protective cover. The drill rod is fixed to the bottom of the driven rod.

[0009] The limiting mechanism is installed at the bottom of the mounting plate and is used to prevent the driven rod from falling off from the slide groove.

[0010] The principle and effect of this technical solution:

[0011] 1. The protective plate is used to block the dust from drilling, thereby protecting the user. By installing the drilling mechanism on the mounting plate, when the user drives the shell to press down, the mounting plate can bear the downward pressure and reaction force, thereby avoiding the direct load bearing of the motor, thereby protecting the motor and extending its service life.

[0012] 2. A plurality of protrusions are formed on the driving rod, and the driving rod and the protrusions are slidably plugged into the transmission groove of the driven rod, so that when the motor drives the driving rod to rotate, the driving rod can also drive the driven rod to rotate through the protrusions, so that the driven rod can drive the drill rod to rotate, thereby having a drilling function, and the driven rod can slide up and down relative to the slide groove and the driving rod, so that the driven rod abuts against the top of the slide groove, and the bottom of the driving rod does not abut against the bottom of the transmission groove at this time, that is, the motor can provide only rotational force but no downward pressure, thereby protecting the motor, and the downward pressure can be borne by the mounting plate, thereby extending the service life of the device, and through the setting of the ball, the sliding friction between the driven rod and the top of the slide groove is converted into rolling friction, so that the mounting plate and the driven rod are not easy to wear, and the service life of the device is extended.

[0013] 3. The setting of the limit mechanism prevents the driven rod from being separated from the driving rod and the slide slot, thereby making the device more stable.

[0014] The utility model is further configured as follows: the drilling mechanism also includes a wear-resistant plate, the wear-resistant plate is installed in the slide groove and sleeved outside the driving rod, and the bottom of the wear-resistant plate is formed with a wear-resistant groove matched with the ball.

[0015] The principle and effect of this technical solution: the setting of the wear-resistant plate and the wear-resistant groove can protect the mounting plate, avoid the situation where the entire mounting plate is made of wear-resistant material, and reduce the difficulty of machining the wear-resistant groove of the mounting plate. The setting of the wear-resistant plate makes the continuous high-speed rotation of the ball and the wear-resistant groove less prone to wear, thereby extending the service life of the device.

[0016] The utility model is further configured as follows: a limiting ring is fixed on the top of the wear-resistant plate, the limiting ring is sleeved outside the driving rod, an elastic piece is sleeved on the outer side of the limiting ring, and the wear-resistant plate is slidably matched with the sliding groove.

[0017] The principle and effect of the technical solution: through the setting of the limit ring and the elastic part, when the user holds the handle of the shell and presses down to drill a hole, the elastic part can buffer the impact force and vibration during drilling, thereby improving the user's comfort, and through the setting of the limit ring, the position of the wear-resistant plate and the elastic part can be limited, so that the elastic part will not be affected by the rotation of the driving rod, and at the same time can stably adjust the position of the wear-resistant plate, and indirectly make the wear-resistant plate abut against the mounting plate, so that after the elastic part exists, the mounting plate can still indirectly provide downward pressure for the drill rod.

[0018] The utility model is further configured as follows: the elastic member is a buffer spring, the top of the buffer spring is fixed to the top of the slide groove, and the bottom of the buffer spring is fixed to the top of the wear-resistant plate.

[0019] The principle and effect of the technical solution: the spring has good ductility. Through the setting of the buffer spring, the wear-resistant groove of the wear-resistant plate can always fit with the ball, so that when the driven rod rotates, the ball can roll and fit in the wear-resistant groove, thereby making the device more stable, thereby avoiding the situation that the device can only start the motor when the drill rod is close to the ground, making the starting conditions of the device more relaxed.

[0020] The utility model is further configured that: the limiting ring is made of rubber.

[0021] The principle and effect of this technical solution: the rubber limit ring can not only play a limiting role, but also absorb the impact force when the drill rod drills into the ground by compressing the limit ring, thereby reducing the shaking feeling of the user's hand and making the device more comfortable when used.

[0022] The utility model is further configured as follows: the limiting mechanism includes a limiting cylinder and a bearing, the limiting cylinder is slidably sleeved on the driven rod, and the limiting cylinder is fixed to the bottom of the mounting plate, the bearing is fixed on the driven rod, and the bearing is slidably fitted in the limiting cylinder.

[0023] The principle and effect of this technical solution: by fixing the driven rod with a bearing, the driven rod can be guided and limited by the bearing when sliding up and down, so that the rotation and lifting of the driven rod are more stable. And by the abutment between the bearing and the bottom of the inner side of the limiting cylinder, the driven rod is prevented from falling off the slide groove when the device is not drilling, so that the continuous use and stability of the driven rod are better, and the storage and storage of the driven rod are convenient.

[0024] The utility model is further configured as follows: a guide rod is installed in the protective cover, a slider is fixed to the lower end of the shell side wall, the slider is slidably mounted on the guide rod, and a compression spring is mounted on the guide rod, the compression spring is located at the bottom of the slider, and the shell and the protective cover are slidably matched.

[0025] The principle and effect of this technical solution: through the sliding insertion of the slider and the guide rod, the shell can compress the compression spring when pressed down, so that the protective cover can be firmly abutted against the ground, making it difficult for the protective cover to be separated from the ground, thereby making the dust-proof effect of the protective cover better, and the setting of the guide rod and the slider can make the sliding of the shell relative to the protective cover more stable, and the compression spring can drive the protective cover to reset for subsequent continued use.
