Description

Technical Field

[0001] This utility model relates to the field of drilling and sampling technology, and in particular to a rock drilling and sampling device. Background Technology

[0002] A rock drilling and sampling device is a specialized piece of equipment used for geological exploration. Its main function is to extract core samples from rock strata for geological analysis and research. However, the drilling and sampling device is equipped with a rack and pinion, and the lifting body is raised and lowered by the cooperation of the lifting operation handle and the rack and pinion. Since the rack and pinion are located on the outside, when the drilling and sampling device is not in use, the exposed rack and pinion are easily damaged due to the lack of a protective structure. At the same time, foreign objects can easily adhere to the rack and pinion, which will affect the flexibility of the lifting body. Utility Model Content

[0003] The main purpose of this invention is to provide a rock drilling and sampling device that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A rock drilling and sampling device includes a base, a square rod, and a lifting body. The square rod is mounted on the upper surface of one end of the base, and the lifting body is sleeved on the square rod. A rack is mounted on the rear surface of the square rod. A lifting operation handle is mounted on one side surface of the lifting body. A motor is mounted on the upper surface of the front end of the lifting body. An end cap is mounted on the top of the square rod. A U-shaped protective cover is embedded inside the square rod. Fasteners are embedded on the upper surface of the end cap near the four corners.

[0006] More preferably, a baffle is installed on the upper rear surface of the square rod, a U-shaped groove is formed inside the square rod, and a limiting groove is formed longitudinally on both sides of the inside of the U-shaped groove. A folding groove communicating with the U-shaped groove is formed on the upper surface of the square rod on both rear sides, and a threaded groove is formed on the upper surface of the square rod near the four corners.

[0007] More preferably, a retaining plate is installed on the upper front surface of the U-shaped protective cover, and flip-up folding rods are installed on both sides of the lower end of the U-shaped protective cover. Columnar sliders embedded in limiting grooves are installed on both sides of the lower end of the folding rods.

[0008] More preferably, the U-shaped groove and the folding rod are both embedded in the U-shaped groove, and a pin is inserted between the folding rod and the U-shaped protective cover.

[0009] More preferably, the lower end of the fastener passes through the end cap and is embedded in the threaded groove, and the upper surface of the end cap has a groove.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] In this invention, by setting up a square rod, an end cap, and a U-shaped protective cover in cooperation, when the sampling device is not in use, the height of the lifting body is lowered and the lower end of the rack is blocked. Then the U-shaped protective cover is pulled up. When the U-shaped protective cover is pulled up to a certain height, the cylindrical slider of the U-shaped protective cover will be blocked by the end cap and cannot rise further. At this time, the U-shaped protective cover is flipped so that the folding rod is flipped to a horizontal state. Then the U-shaped protective cover is flipped down again until the U-shaped protective cover blocks the rack. The U-shaped protective cover and the lifting body cooperate to prevent the rack from being exposed. The baffle of the square rod can block the upper end of the U-shaped protective cover.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-5The rock drilling and sampling device shown includes a base 1, a square rod 2, and a lifting body 3. The square rod 2 is installed on the upper surface of one end of the base 1, and the lifting body 3 is sleeved on the square rod 2. A rack 6 is installed on the rear surface of the square rod 2. A lifting operation handle 4 is installed on one side surface of the lifting body 3. A motor 5 is installed on the upper surface of the front end of the lifting body 3. An end cap 7 is installed on the top of the square rod 2. A U-shaped protective cover 9 is embedded inside the square rod 2. Fasteners 8 are embedded on the upper surface of the end cap 7 near the four corners.

[0020] In a preferred embodiment: a baffle 201 is installed on the upper rear surface of the square rod 2, a U-shaped groove 202 is provided inside the square rod 2, a limiting groove 204 is provided longitudinally on both sides inside the U-shaped groove 202, a folding groove 203 communicating with the U-shaped groove 202 is provided on the upper surface of the square rod 2 and on both rear sides, and a threaded groove 205 is provided on the upper surface of the square rod 2 and near the four corners.

[0021] In the above structure, after the U-shaped protective cover 9 is removed from the U-shaped groove 202 and flipped over to cover the rack 6, the baffle 201 can cover the upper end of the U-shaped protective cover 9. Since the cylindrical slider 901 is embedded in the limiting groove 204 and the end cap 7 covers the upper end of the limiting groove 204, the cylindrical slider 901 can not continue to rise after moving up a certain height in the limiting groove 204, thereby preventing the folding rod 903 from detaching from the U-shaped groove 202.

[0022] In a preferred embodiment: a clamping plate 902 is installed on the upper front surface of the U-shaped protective cover 9, and flip-up folding rods 903 are installed on both sides of the lower end of the U-shaped protective cover 9. Columnar sliders 901 embedded in the limiting grooves 204 are installed on both sides of the lower end of the folding rods 903.

[0023] In the above structure, the clamping plate 902 prevents the U-shaped protective cover 9 from being completely embedded in the U-shaped groove 202. This makes it convenient to pull the U-shaped protective cover 9 out of the U-shaped groove 202 using the clamping plate 902. After the U-shaped protective cover 9 flips over to cover the rack 6, the U-shaped protective cover 9 and the rack 6 come into contact with each other. The coefficient of friction between the U-shaped protective cover 9 and the rack 6 must ensure that the U-shaped protective cover 9 will not flip over due to the vibration of the sampling device, thus preventing the rack 6 from being exposed.

[0024] In a preferred embodiment, both the U-shaped groove 202 and the folding rod 903 are embedded in the U-shaped groove 202, and a pin is inserted between the folding rod 903 and the U-shaped protective cover 9.

[0025] In the above structure, since the pin is inserted between the folding rod 903 and the U-shaped protective cover 9, the folding rod 903 and the U-shaped protective cover 9 can be flipped and folded together.

[0026] In a preferred embodiment: the lower end of the fastener 8 passes through the end cap 7 and is embedded in the threaded groove 205, and the upper surface of the end cap 7 has a groove 701.

[0027] In use, a sampling drill bit is installed at the output end of the motor 5. The lifting body 3 can be raised and lowered by rotating the lifting operation handle 4. When the motor 5 is started, it can drive the sampling drill bit to rotate and sample. When the sampling device is not in use, the height of the lifting body 3 is lowered and the lower end of the rack 6 is covered. Then the U-shaped protective cover 9 is pulled up. When the U-shaped protective cover 9 is pulled up to a certain height, the cylindrical slider 901 of the U-shaped protective cover 9 will be blocked by the end cover 7 and cannot continue to rise. At this time, the U-shaped protective cover 9 is flipped so that the folding rod 903 is flipped to a horizontal state. Then the U-shaped protective cover 9 is flipped down again until the U-shaped protective cover 9 covers the rack 6. The U-shaped protective cover 9 and the lifting body 3 cooperate to prevent the rack 6 from being exposed. The baffle 201 of the square rod 2 can cover the upper end of the U-shaped protective cover 9.
