Description

Technical Field

[0001] This utility model relates to the field of surveying and sampling technology, specifically a sampling device for land and mineral exploration. Background Technology

[0002] Land and mineral exploration and sampling is a core part of geological exploration. By systematically collecting samples of soil, rocks, and ores, and analyzing their composition, structure, and physicochemical properties, scientific evidence is provided for resource assessment and development planning.

[0003] The sampling device currently in use mainly includes a vehicle body, a chain drive mechanism (handwheel, gear, chain and drive shaft), a gasoline impact drill, a work box and a pair of guide rods. A pair of vertical guide rods are fixedly installed on the vehicle body. The work box can slide along the guide rods through sleeves fixed at both ends. The chain drive mechanism can lift the work box and the gasoline impact drill fixedly installed at the center of the work box, which facilitates the replacement of the sampling drill and extension tube.

[0004] During operation, the gasoline impact drill relies on the combined action of the generated impact force, its own weight, and the pressure manually applied on the chain drive mechanism to achieve downward tunneling. After completion, it is lifted and reset, and then samples are taken out from various parts of the extension tube. Since the impact force generated by the gasoline impact drill acts in the vertical direction, the upward impact force does not perform tunneling work, and there is still room for improvement in work efficiency.

[0005] Therefore, in order to solve the above problems, a sampling device for land and mineral exploration is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a sampling device for land and mineral exploration, which further utilizes upward impact force to assist tunneling operations, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for land and mineral exploration, comprising a vehicle body, a chain drive mechanism, a gasoline impact drill, a work box, and a pair of guide rods. The work box has through holes at its four corners, each through which a sleeve is inserted. A housing is fixedly installed between a pair of vertically aligned sleeves, and the vertically aligned sleeves are slidably mounted on the same guide rod. Connecting beams are fixedly installed between the upper and lower sleeves. Both ends of the chain in the chain drive mechanism are fixedly mounted to the connecting beams. A transmission mechanism is installed on the housing, one end of which is connected to the work box, and the other end of which is fitted with a pressure plate for pressing against the guide rods. The pressure plate is located inside the housing.

[0008] Specifically, the transmission mechanism includes a support base, a guide wheel, and a transmission rod. The support base is fixedly installed inside the working box. The support base has a horizontally opened elongated hole. The casing has a through groove. The transmission rod is rotatably mounted on the through groove. One end of the transmission rod is rotatably mounted with a guide wheel. The guide wheel travels in the elongated hole. The other end of the transmission rod is rotatably mounted with a pressure plate through a rotating seat.

[0009] Furthermore, the end of the transmission rod near the working box is lower than the end of the transmission rod near the pressure plate, and the angle between the transmission rod and the horizontal plane is 30° to 35°.

[0010] Furthermore, when the working box moves upward relative to the housing, the transmission mechanism drives the pressure plate to press against the guide rod; when the working box moves downward relative to the housing, the transmission mechanism drives the pressure plate to separate from the guide rod.

[0011] Furthermore, the number of transmission rods connected to each of the pressure plates is 2 to 4.

[0012] Specifically, pressure plates are provided on one or both sides of the guide rod.

[0013] Specifically, the guide rod is a rectangular rod-shaped structure, and the internal shape of the sleeve is adapted to the guide rod, while the pressure plate is a rectangular plate-shaped structure.

[0014] Specifically, a friction plate is fixedly installed on the side of the pressure plate near the guide rod, and the friction plate has grooves evenly formed on the side near the guide rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Through the separate design of external modules (working box, gasoline impact drill) and internal modules (connecting beam, casing and sleeve), and the connection between the external and internal modules through a transmission mechanism, the upward impact force generated by the gasoline impact drill can be converted into a clamping force on the guide rod, generating a downward reaction force that, together with the original impact force, its own weight, and manual pressure, forms a four-way force superposition, which can improve the work efficiency during tunneling.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Structure and operating principle of existing sampling devices:

[0024] The existing sampling device includes a vehicle body (frame, wheels and support legs), a chain drive mechanism 7 (handwheel, gear, chain and drive shaft), a gasoline impact drill 10, a work box 2 and a pair of guide rods 9. The gasoline impact drill 10 is fixedly installed in the middle of the work box 2. The gear and handwheel are installed on the vehicle body through the drive shaft. Turning the handwheel can drive the chain through the gear.

[0025] The work box can slide along the guide rod 9 through the sleeves fixed at both ends. The two ends of the chain in the chain drive mechanism 7 are directly fixedly connected to the work box 2. The chain drive mechanism 7 can lift and press down the work box 2 and the gasoline impact drill 10 fixedly installed at the center of the work box 2.

[0026] The vehicle body is easy to move and place stably. The gasoline impact drill 10 is an existing component with a gasoline engine, transmission system, impact mechanism, drill bit and switch button. Using gasoline as a power source is more in line with the working conditions of land and mineral exploration and sampling. There is no need to carry a power supply and air compressor. The extension tube and sampling drill can be flexibly installed and removed at the output end of the gasoline impact drill 10 to complete the exploration and sampling operation.

[0027] The above describes the structure and operating principle of the existing equipment, which will not be elaborated upon here.

[0028] Please see Figure 1 , Figure 2 and Figure 3 A sampling device for land and mineral exploration is provided, with the following improvements:

[0029] The device includes a vehicle body, a chain drive mechanism 7, a gasoline impact drill 10, a work box 2, and a pair of guide rods 9. The chain drive mechanism 7 and a pair of guide rods 9 are installed on the vehicle body. The gasoline impact drill 10 is fixedly installed in the center of the work box 2. Through holes are opened at the four corners of the work box 2, and sleeves 8 are inserted through the through holes. A housing 3 is fixedly installed between the upper and lower aligned sleeves 8, and the upper and lower aligned sleeves 8 are slidably assembled on the same guide rod 9. Connecting beams 1 are fixedly installed between the upper sleeves 8 and between the lower sleeves 8. The two ends of the chain in the chain drive mechanism 7 are fixedly assembled with the connecting beams 1 respectively.

[0030] With the above structure, the working box 2 and the gasoline impact drill 10 form an external module, the connecting beam 1, the casing 3 and the sleeve 8 form an internal module, and the chain drive mechanism 7 is connected to the internal module. Unlike the traditional method, the working box 2 and the gasoline impact drill 10 are directly raised and lowered through the transmission of the chain drive mechanism 7.

[0031] In addition, the housing 3 is equipped with a transmission mechanism 4. One end of the transmission mechanism 4 is connected and assembled with the working box 2, and the other end of the transmission mechanism 4 is equipped with a pressure plate 5 for pressing against the guide rod 9. The pressure plate 5 is located inside the housing 3.

[0032] The transmission mechanism 4 can flexibly connect the external module and the internal module. The vertical vibration generated by the gasoline impact drill 10 during operation can be transmitted to the work box 2, causing the external module and the internal module to have relative displacement. The relative displacement can be used to make the pressure plate 5 press against or separate from the guide rod 9.

[0033] Please see Figure 4 The specific structure of the transmission mechanism 4 is as follows:

[0034] The transmission mechanism 4 includes a support base 41, a guide wheel 42, and a transmission rod 43. The support base 41 is fixedly installed inside the working box 2. The support base 41 has a horizontally opened elongated hole. The sleeve 3 has a through groove. The transmission rod 43 is rotatably assembled in the through groove. One end of the transmission rod 43 is rotatably mounted with the guide wheel 42. The guide wheel 42 travels in the elongated hole. The other end of the transmission rod 43 is rotatably assembled with the pressure plate 5 through a rotating seat.

[0035] During tunneling operations, the force applied by the hand on the handwheel is transmitted through the sprocket and chain to exert a downward force on the internal module, ultimately acting on the pivot point between the transmission rod 43 and the through slot, i.e., the "fulcrum". The pivot point exerts a downward force. During vibration, the working box 2 and the casing 3 will have relative displacement. The slightly swaying transmission rod 43 can transmit the force on the working box 2 to the pressure plate 5, converting the vertical linear motion into the rotational pressing action of the pressure plate 5. At the same time, the movement of the guide wheel 42 in the elongated hole can compensate for the horizontal displacement of the lower end of the transmission rod 43, avoiding motion interference.

[0036] The end of the transmission rod 43 near the working box 2 is lower than the end of the transmission rod 43 near the pressure plate 5, and the angle between the transmission rod 43 and the horizontal plane is 30° to 35°. That is, when the guide wheel 42 at the lower end of the transmission rod 43 moves to the end of the elongated hole near the sleeve 3, the angle between the transmission rod 43 and the horizontal plane is 35°, and when the guide wheel 42 moves to the end of the elongated hole away from the sleeve 3, the angle between the transmission rod 43 and the horizontal plane is 30°.

[0037] The inclined transmission rod 43 can better transmit impact force. When the working box 2 moves upward relative to the housing 3, the transmission mechanism 4 drives the pressure plate 5 to press against the guide rod 9; when the working box 2 moves downward relative to the housing 3, the transmission mechanism 4 drives the pressure plate 5 to separate from the guide rod 9.

[0038] To ensure the strength of the transmission rod 43 in transmitting vibration and the swing posture of the pressure plate 5 parallel to the guide rod 9, the number of transmission rods 43 connected to each pressure plate 5 is 2 to 4.

[0039] A pressure plate 5 is provided on one or both sides of the guide rod 9. The pressure plate 5 on one side of the guide rod 9 simplifies the structure and reduces manufacturing costs, making it suitable for lightweight equipment with low operating intensity. The pressure plates 5 on both sides of the guide rod 9 can form symmetrical clamping, making it suitable for heavy equipment with high operating intensity. The configuration should be reasonable according to the usage environment.

[0040] The guide rod 9 has a rectangular rod-shaped structure, and the internal shape of the sleeve 8 is adapted to the guide rod 9. The pressure plate 5 has a rectangular plate-shaped structure, which can ensure that the pressure plate 5 and the guide rod 9 have a large working surface when they are pressed together, thus ensuring uniform force application.

[0041] A friction plate 6 is fixedly installed on the side of the pressure plate 5 near the guide rod 9. The material of the friction plate 6 is preferably aramid fiber composite material, which ensures the coefficient of friction and avoids metal wear. The friction plate 6 has grooves evenly opened on the side near the guide rod 9. The grooves are used to enhance the friction force and also have a heat dissipation function to avoid the high temperature caused by friction from causing the friction plate 6 to age faster and to ensure braking reliability.

[0042] How the example works:

[0043] When in use, move the entire unit to the designated position and place it stably. First, lift the work box 2 and the gasoline impact drill 10 through the handwheel and chain drive mechanism 7 to facilitate the installation of the extension tube and sampling drill at the output end of the gasoline impact drill 10.

[0044] During operation, the gasoline impact drill 10 is started by the switch button on the front of the work box 2. At this time, the gasoline impact drill 10 generates vertical vibration and rotates the extension tube and sampling drill. Through the combined action of the impact force, its own weight and the pressure manually applied on the chain drive mechanism, the purpose of gradually digging downward is achieved.

[0045] At the same time, the vertical vibration will be transmitted to the working box 2, giving the working box 2 the kinetic energy to move up and down. When the working box 2 moves upward relative to the casing 3, the transmission mechanism 4 drives the pressure plate 5 to press against the guide rod 9, which plays a braking role and prevents the working box 2, casing 8 and other structures from moving excessively upward along the guide rod 9. The resulting downward reaction force, together with the original force, forms the combined action of four forces, which is more conducive to tunneling operations.

[0046] When the working box 2 moves downward relative to the casing 3, the transmission mechanism 4 drives the pressure plate 5 to separate from the guide rod 9. The working box 2, casing 8 and other structures can continue to move downward along the guide rod 9. At this time, there is no downward reaction force, but there are still the initial three forces to ensure normal tunneling operation and flexible use.

[0047] After the tunneling reaches the designated depth, an extension pipe is installed between the extension pipe and the gasoline impact drill 10 to extend the sampling depth.

[0048] The extension tube and sampling drill are pulled upwards. At this time, the chain lifts the sleeve 8 and the housing 3 through the connecting beam 1. The fulcrum has an upward force, which causes the working box 2 to move downwards relative to the housing 3. The pressure plate 5 and the guide rod 9 will also separate without affecting the lifting action. The extension tube is taken out in sequence and the machine is stopped and disassembled to obtain the survey sample.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0050] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
