Description

Technical Field

[0001] This utility model relates to the field of mineral development equipment technology, specifically to a drilling rig sampling and handling device. Background Technology

[0002] Currently, when sampling mineral samples, the drill bit of the drilling rig is inserted into the sample and then removed from the borehole. A baffle is then placed over the borehole to seal it, preventing any sample adhering to the drill bit from slipping back into the borehole due to gravity. The sample is then gently shaken off the drill bit and transferred entirely to the baffle. Finally, the baffle is tilted to pour the sample into a pre-prepared ton bag, completing the sampling and transfer process.

[0003] However, the current process of sampling mineral samples requires manual pouring of the sample from the baffle into the ton bag, which is inefficient and labor-intensive. Utility Model Content

[0004] The problem this invention aims to solve is that currently, during the sampling process of mineral samples, it is necessary to manually pour the sample from the baffle into the ton bag, which is inefficient and labor-intensive.

[0005] Technical solution

[0006] A drilling rig sampling and handling device includes a mobile trolley, a receiving hopper, and a lifting mechanism. The mobile trolley has an installation cavity extending vertically. The receiving hopper is slidably installed in the installation cavity. The top of the receiving hopper is open, and its bottom has a discharge port. The lifting mechanism is installed on the mobile trolley and is used to drive the receiving hopper to rise and fall. The discharge port of the receiving hopper is provided with a gate mechanism, which is used to control the opening and closing of the discharge port.

[0007] According to one embodiment of the present invention, the mobile trolley includes a frame and a wheel mechanism, and the mounting cavity is disposed on the frame.

[0008] According to one embodiment of the present invention, at least one guide rail is vertically installed on the inner wall of the mounting cavity, and at least one slider corresponding to each guide rail is installed on the outer side of the receiving hopper, and the slider slides on the corresponding guide rail.

[0009] According to one embodiment of the present invention, the lifting mechanism includes at least a hydraulic cylinder, at least one fixing plate is provided on the side of the receiving hopper, the hydraulic cylinder is vertically installed in the mounting cavity of the frame, and the top end of the hydraulic cylinder is fixed to the fixing plate.

[0010] According to one embodiment of the present invention, the receiving hopper includes a pipe body and a hopper body connected to each other. The pipe body is square tube-shaped, and the hopper body is square funnel-shaped. The top opening of the hopper body is connected to the bottom of the pipe body, and the bottom of the hopper body is provided with a square tube. The internal channel of the square tube forms the discharge port.

[0011] According to one embodiment of the present invention, the side wall of the square tube is provided with an insertion hole, and the gate mechanism includes an insertion plate, which is adapted to the insertion hole.

[0012] According to one embodiment of the present invention, the gate mechanism includes a discharger, which is installed at the bottom of the square tube.

[0013] According to one embodiment of the present invention, a handlebar mechanism is installed on the frame, and a protective sleeve is fitted onto the handlebar mechanism.

[0014] According to one embodiment of the present invention, the wheel mechanism includes four wheels, each wheel including a steel hub and an anti-slip rubber wheel disposed on the steel hub.

[0015] According to one embodiment of the present invention, the mobile trolley is equipped with a controller and a battery, the hydraulic cylinder is signal-connected to the controller, and the battery is used to power the hydraulic cylinder and the controller.

[0016] The beneficial effects of this utility model are:

[0017] First, use the lifting mechanism to lower the height of the receiving hopper. After the drill bit is removed from the borehole, the worker pushes the sampling and transporting device of the drill rig directly under the drill bit, so that the receiving hopper is located between the top opening of the borehole and the drill bit. Then, gently shake the mineral sample off the drill bit so that all the mineral sample falls into the receiving hopper. Then, push the sampling and transporting device of the drill rig away directly under the drill bit. Next, use the lifting mechanism to raise the height of the receiving hopper so that the discharge port of the receiving hopper is raised to the set height for easy discharge. Then, place the ton bag directly under the discharge port of the receiving hopper and open the bag opening. Finally, control the gate mechanism to put the discharge port in the discharge state, and the mineral sample in the receiving hopper flows into the ton bag from the discharge port.

[0018] This allows for rapid transfer and bagging of mineral samples, eliminating the need for manual pouring of samples from the baffle into the ton bags, thus improving sampling efficiency and reducing the workload for workers. Furthermore, since the bagging process does not occur below the drill bit, it also enhances the safety of the bagging operation. Attached Figure Description

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figures 1-4 As shown, one embodiment of this utility model provides a drilling rig sampling and handling device, including a mobile trolley, a receiving hopper 3, and a lifting mechanism. The mobile trolley is provided with an installation cavity extending in a vertical direction. The receiving hopper 3 is slidably installed in the installation cavity. The top of the receiving hopper 3 is open and its bottom has a discharge port. The lifting mechanism is installed on the mobile trolley and is used to drive the receiving hopper 3 to rise and fall. A gate mechanism is provided at the discharge port of the receiving hopper 3, and the gate mechanism is used to control the opening and closing of the discharge port.

[0027] In this embodiment, the height of the receiving hopper 3 is first lowered using a lifting mechanism. After the drill bit is removed from the borehole, the worker pushes the sampling and transporting device of the drilling rig directly below the drill bit, so that the receiving hopper 3 is located between the top opening of the borehole and the drill bit. Then, the ore sample on the drill bit is gently shaken off, so that all the ore sample falls into the receiving hopper 3. Then, the sampling and transporting device of the drilling rig is pushed away directly below the drill bit. Next, the height of the receiving hopper 3 is raised using a lifting mechanism, so that the discharge port of the receiving hopper 3 is raised to a set height for easy discharge. Then, the ton bag is placed directly below the discharge port of the receiving hopper 3 and the bag opening is opened. Finally, the gate mechanism is controlled to put the discharge port in the discharge state, and the ore sample in the receiving hopper 3 flows from the discharge port into the ton bag.

[0028] This allows for rapid transfer and bagging of mineral samples, eliminating the need for manual pouring of samples from the baffle into the ton bags, thus improving sampling efficiency and reducing the workload for workers. Furthermore, since the bagging process does not occur below the drill bit, it also enhances the safety of the bagging operation.

[0029] In a preferred embodiment, the mobile trolley includes a frame 1 and a wheel mechanism 2 mounted on the frame 1, wherein the interior of the frame 1 has a mounting cavity extending in a vertical direction.

[0030] The frame 1 is constructed from high-strength, lightweight aluminum alloy, which ensures the vehicle's sturdiness and durability while reducing its overall weight.

[0031] In this embodiment, the receiving hopper 3 includes a pipe body 301 and a hopper body 302 connected to each other. The pipe body 301 is square tube-shaped, and the hopper body 302 is square funnel-shaped. The top surface of the hopper body 302 is connected to the bottom surface of the pipe body 301. The bottom of the hopper body 302 is provided with a square tube, and the internal channel of the square tube forms a discharge port.

[0032] It should be noted that the funnel-shaped hopper 302 is designed to facilitate the pouring of the ore sample into the ton bag. Furthermore, the receiving hopper 3 has a capacity of approximately 1 cubic meter to ensure sufficient space to receive the ore sample shaken off the drill bit.

[0033] In this embodiment, the gate mechanism includes an insert plate 7. A matching insertion hole is provided on the side of the square tube. The insert plate 7 is inserted into the insertion hole to close the discharge port. During material feeding, it is only necessary to control the depth of the insert plate 7 inserted into the insertion hole or to pull the entire insert plate 7 out.

[0034] Optionally, the gate mechanism is a discharger, which is sealed to the bottom outlet of the square tube.

[0035] Optionally, the receiving hopper 3 includes a pipe body 301 and a hopper body 302 connected to each other. The pipe body 301 is cylindrical, and the hopper body 302 is funnel-shaped. The top surface of the hopper body 302 is connected to the bottom surface of the pipe body 301, and the bottom of the hopper body 302 is provided with a cylindrical tube. In this embodiment, the gate mechanism is a discharge device, and the discharge device and the bottom opening of the cylindrical tube are sealed together by a flange.

[0036] In this embodiment, for ease of description, the direction of movement of the wheel mechanism 2 is referred to as the front-to-back direction of the drilling rig sampling and transport device. The lifting mechanism includes at least two hydraulic cylinders 8, such as... Figure 4 As shown, a support plate 101 is welded to the inner wall of the front and rear sides of the frame 1, and at least one vertically arranged hydraulic cylinder 8 is fixedly installed on the top of the support plate 101. A fixing plate 303 is fixedly installed on the front and rear sides of the hopper 302 of the receiving hopper 3, and the top of the hydraulic cylinder 8 is fixedly connected to the fixing plate 303 located directly above it. In this way, the height of the receiving hopper 3 is adjusted by controlling the extension and retraction of the hydraulic cylinder 8.

[0037] It should be noted that when placing the opening of the ton bag below the discharge port of receiving hopper 3, if the discharge port of receiving hopper 3 is too close to the ground, the following two problems will occur: First, it will be difficult to place the opening of the ton bag below the discharge port. Second, when filling the ore sample bag, the discharge port of receiving hopper 3 being too close to the ground will limit the amount of ore sample that the ton bag can hold; that is, the ton bag cannot fully unfold, thus affecting its capacity.

[0038] In this embodiment, during bagging, the moving trolley is first pushed away from under the drill bit, and then the hydraulic cylinder 8 is extended to push the receiving hopper 3 upward. The discharge port of the receiving hopper 3 is further and further away from the ground. When the receiving hopper 3 reaches a fixed height, the ton bag is placed under the receiving hopper 3. At this time, the ton bag can be unfolded and opened relatively easily. Finally, the insert plate 7 on the discharge port is removed, and the mineral sample in the receiving hopper 3 naturally flows into the ton bag.

[0039] To ensure the stability of receiving hopper 3 during lifting, such as Figure 3 As shown, at least one guide rail 4 is fixedly installed on the left and right inner walls of the mounting cavity of the frame 1, and at least one slider 304 is slidably installed on each guide rail 4. Each slider 304 is fixedly connected to the tube body 301 of the receiving hopper 3. In this way, the extension and retraction of the hydraulic cylinder 8 can push the receiving hopper 3 to rise and fall along the length of the guide rail 4, ensuring the stability of the receiving hopper 3 when it rises and falls.

[0040] In this embodiment, as Figure 1 and Figure 2 As shown, a handlebar mechanism 5 is installed on the rear end of the frame 1. The handlebar mechanism 5 includes two handles, the same end of which is welded to the frame 1, and at least one connecting rod is welded between the two handles.

[0041] When workers grip the handle to push the moving trolley, their palms are prone to injury due to prolonged friction with the handle. Therefore, in this embodiment, a protective sleeve 501 is fitted onto the end of the handle. The protective sleeve 501 is a non-slip rubber sleeve, which not only prevents slippage, making it easier for the operator to control the direction of the moving trolley, but also protects the worker's palms.

[0042] It should be clear that the wheel mechanism 2 in this embodiment includes an axle, four wheels, and brake components. The axle is mounted on the bottom of the frame, and the wheels are mounted on the ends of the axle. Each wheel includes a steel hub and anti-slip rubber wheels mounted on the steel hub. Figure 1 as well as Figure 2 As can be seen, the wheels have a large outer diameter and use steel hubs, which gives the drilling rig's sampling and transport device a strong load-bearing capacity, allowing it to carry more mineral samples. As for the type of braking components, there are no specific restrictions, as long as they can function as brakes.

[0043] It should be noted that the wheel mechanism 2 can adopt a four-wheel independent suspension system. When facing various complex road conditions, the four-wheel independent suspension can automatically adjust the movement mode of the wheels, enabling the mobile trolley to adapt to driving on complex road surfaces such as asphalt, gravel, and mud.

[0044] In a preferred embodiment, a controller 6 and a battery are installed at the rear end of the frame 1. The hydraulic cylinder 8 is signal-connected to the controller 6, which controls the operation of the hydraulic cylinder 8. The battery supplies power to the hydraulic cylinder 8 and the controller 6.

[0045] It is important to understand that the controller 6 controls the extension and retraction, opening and closing of the hydraulic cylinder 8 by sending signals to the solenoid valve in the hydraulic system. Upon receiving the signal, the solenoid valve changes the flow direction of the hydraulic oil, thereby controlling the extension and retraction of the hydraulic cylinder 8. For example, when the solenoid valve is open, hydraulic oil flows into the hydraulic cylinder 8, pushing the piston rod to extend; when the solenoid valve is closed, the hydraulic oil flows back, and the piston rod retracts under the force of the spring or the load.

[0046] To detect and limit the lifting stroke of the hopper 3, photoelectric sensors are installed at appropriate positions near the top and bottom of the guide rail 4. A trigger plate is then installed on the side of the slider 304. When the slider 304 rises along the guide rail 4 to its first extreme position, the light emitted by the photoelectric sensor at the top of the guide rail 4 is blocked by the trigger plate on the slider 304, and the controller 6 receives a signal. Similarly, when the slider 304 descends along the guide rail 4 to its second extreme position, the light emitted by the photoelectric sensor at the bottom of the guide rail 4 is blocked by the trigger plate on the slider 304, and the controller 6 also receives a signal.

[0047] When using the sampling and transport device of this drilling rig, pressing the descent button on the controller 6 will cause the controller 6 to control the hydraulic cylinder 8 to shorten the set length, thereby lowering the height of the receiving hopper 3. After the drill bit is removed from the borehole, the worker pushes the sampling and transport device of this drilling rig directly below the drill bit, so that the receiving hopper 3 is positioned between the top opening of the borehole and the drill bit. Then, the height of the receiving hopper 3 is appropriately adjusted so that the lower half of the drill bit extends into the interior of the receiving hopper 3, to prevent the mineral sample on the drill bit from being blown away by strong winds when it falls. Next, the mineral sample on the drill bit is gently shaken off, so that all the mineral sample falls into the receiving hopper 3. Then, the height of the receiving hopper 3 is lowered so that the receiving hopper 3 is lower than the drill bit. Next, the sampling and transporting device of this drilling rig is pushed away from directly below the drill bit. Then, the up button on the controller 6 is pressed, and the controller 6 controls the cylinder 8 to extend to the set length to raise the height of the receiving hopper 3. Then, the ton bag is placed directly below the discharge port of the receiving hopper 3 and the bag opening is opened. Finally, the insert plate 7 is pulled out, and the mineral sample in the receiving hopper 3 flows into the ton bag from the discharge port.

[0048] In this way, all the mineral samples on the drill bit can be collected, avoiding the problem of the samples falling onto the baffle and scattering on the ground. It also facilitates the bagging of mineral samples, eliminating the need for workers to pour the mineral samples from the baffle into ton bags, thus improving sampling efficiency and reducing the workload of workers.
