Description

Technical Field

[0001] This utility model belongs to the field of mining equipment, and specifically relates to a convenient and safe ore sampling device. Background Technology

[0002] During the mining process, in addition to the mining itself, ore samples need to be taken and tested at conveying sites such as ore dressing plants to ensure ore quality. However, when sampling at conveying sites such as ore dressing plants, the high speed of the conveyor belt combined with the weight of the ore generates a huge impact force. Manual sampling with hand tools can easily cause tools to fly away and pose a danger to workers. Therefore, automatic sampling devices are needed for sampling. However, when using existing technology, although automatic sampling devices can perform certain sampling functions, they are easily damaged by the impact of high-speed ore during sampling, and maintenance is inconvenient. It is often necessary to stop the ore conveying, which affects production efficiency. Utility Model Content

[0031] The device employs a sampling mechanism located below the side face of the conveyor belt's discharge end. This mechanism utilizes a sampling trolley mounted on a platform that extends towards the discharge point. By observing the parabolic trajectory of the ore along the conveyor belt, it's observed that the trajectories differ depending on the size and weight of the ore. Based on this difference, the device is positioned at an appropriate location for sampling. The trolley extends from the side face of the conveyor belt's discharge end to collect the ore dropped at a suitable location. After sampling, the trolley is retracted, preventing damage from sampling heavy ore and prolonged impact, thus minimizing the impact on the equipment. Due to the influence of the device, during sampling, the trolley is limited by the wheel grooves, which can prevent it from being impacted and tilted, ensuring smooth operation. After sampling, the ore is guided by the inclined surface of the channel and automatically slides down to the discharge port. Then, controlled by the automatic sealing structure, the trolley can be retracted to automatically sample and discharge, realizing fully automatic sampling. It can also be operated remotely. At the same time, the device structure is clear and easy to maintain and repair. During maintenance and repair, since all parts are not in contact with the conveyor belt or on the conveying route, maintenance and repair can be carried out without stopping the conveyor, avoiding the inconvenience of downtime affecting production efficiency.

Detailed Implementation

[0041] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0042] Example 1:

[0043] This utility model provides a convenient and safe ore sampling device: its structure includes a sampling device 1 and a conveyor belt 4;

[0044] The sampling device 1 is located on the side end face of the material drop point at the four ends of the conveyor belt;

[0045] The sampling device 1 includes a first platform 101, a wheel groove 102, a sampling trolley 103, a discharge port 104, a first power source 108, an assembly frame 109, a guide pipe 112, a channel 115, wheels 116, a receiving hopper 118, and an automatic sealing structure 119. The assembly frame 109 is fixed on the first platform 101. A wheel groove 102 is formed between the side end of the assembly frame 109 and the first platform 101. The sampling trolley 103 is assembled between the assembly frames 109 and one end of the trolley 103 passes through the assembly frame 109. The side of the sampling trolley 103 passing through the assembly frame 109 faces downwards towards the tail end of the conveyor belt 4. Wheels 116 are mounted on both sides of the bottom of the sampling trolley 103, and the wheels 116 are fitted into the wheel grooves 102. The first power source 108 is used to drive the sampling trolley 103 on the first platform. The sampling trolley 103 moves on platform 101. The wheel groove 102 is used for anti-tilting stability and movement limit of the sampling trolley 103. The top of the sampling trolley 103 is provided with a U-shaped groove 115. The groove 115 passes through the sampling trolley 103 from top to bottom on the side of the sampling trolley 103 that passes through the assembly frame 109. The bottom of the groove 115 is a slope that slopes downward toward the discharge port 104. The guide pipe 112 passes through and is fixed on the first platform 101. The top of the guide pipe 112 is fixed with a receiving hopper 118. The receiving hopper 118 is located directly below the discharge port 104. The sampling trolley 103 is also equipped with an automatic sealing structure 119, which is used for opening and closing control of the discharge port 104.

[0046] Furthermore, the travel of the sampling trolley 103 extending out of the assembly frame 109 is greater than or equal to the minimum distance between the assembly frame 109 and the centerline of the conveyor belt 4 in the conveying direction.

[0047] Furthermore, the top of the receiving hopper 118 is larger than the discharge port 104.

[0048] Furthermore, the outer side of the wheel 116 is wrapped with a rubber layer, which can increase the vibration reduction between the trolley and the whole device and reduce the impact of the trolley on the whole device when it is impacted.

[0049] During use, observe the parabolic trajectory of the ore on the conveyor belt. Since the ore varies in size and weight, the parabolic trajectories will differ depending on the size of the ore. Based on this difference, set the device at a suitable sampling location so that the sampling trolley 103 can sample ore of appropriate size and weight. After setting the position, when sampling is needed, the sampling trolley 103 will be driven by the first power source 108 to move towards the discharge point of the conveyor belt 4. After moving the sampling trolley 103 to the fixed position, the first power source 108 will retract the sampling trolley 103. At this time, the sampling trolley 103 will collect and sample the dropped ore, avoiding damage caused by sampling heavy ore and prolonged impact, and reducing the impact on the device. During sampling, the sampling trolley 103 is subjected to pressure from the wheel groove 102 by the wheels 116. The limit switch prevents the ore from tilting up when impacted, ensuring smooth operation. After sampling, the ore slides down the trough 115 of the sampling trolley 103 toward the discharge port 104. At this time, the discharge port 104 can be opened and closed by the automatic sealing structure 119, so that the sampling trolley 103 is fully retracted before the discharge port 104 is opened, allowing the sampled ore to fall into the receiving hopper 118 through the discharge port 104, and then be guided and transported to a fixed position by the guide pipe 112 connected to the receiving hopper 118. This achieves fully automatic sampling and can be operated remotely. At the same time, the device has a clear and easy-to-understand structure, which facilitates maintenance and repair. During maintenance and repair, since all components are not in contact with the conveyor belt 4 and are not on the conveying route, maintenance and repair can be carried out without stopping the conveyor, avoiding the inconvenience of downtime affecting production efficiency.

[0050] Example 2:

[0051] Compared to the previous embodiments, the sampling device 1 in this embodiment further includes a second power source 106, a second platform 107, a guide rail 113, a moving groove 114, and a pulley 117. The guide rail 113 is fixed on the top of the second platform 107 and is arranged along the conveying direction of the conveyor belt 4. The pulley 117 is rotatably mounted on the bottom of the first platform 101 and slidably mounted on the guide rail 113. The second power source 106 is used to drive the first platform 101 to move along the guide rail 113 on the second platform 107. The moving groove 114 is provided through the second platform 107 from top to bottom and is used for the through mounting of the guide tube 112.

[0052] Furthermore, the second power source 106 is a lead screw structure, an electric push rod, a hydraulic rod, a linear motor, a motor gear transmission structure, a motor chain transmission structure, or a motor belt transmission structure.

[0053] In use, the first platform 101 of the sampling trolley 103 can also be driven by the second power source 106 to move along the conveying direction of the conveyor belt 4 on the second platform 107. The sampling trolley 103 can remotely or automatically adjust the sampling and receiving position according to the conveyor belt speed and the type of ore, so as to facilitate quick adjustment of the sampling position and enable the sampling trolley 103 of the device to better ensure the receiving and sampling of ore at the appropriate position. At the same time, the sampling trolley 103 can be quickly adjusted to sample different sizes of ore as needed, which is convenient and fast, while the rest of the structure and effect remain unchanged.

[0054] Example 3:

[0055] Compared to the previous embodiments, the sampling device 1 in this embodiment further includes a collection hopper 110 and a collection device 111. The collection hopper 110 is fixed at the bottom of the second platform 107 where it is penetrated by the moving groove 114. The width of the top of the collection hopper 110 is greater than or equal to the length of the moving groove 114. The collection hopper 110 is used to guide the sampled ore from the guide pipe 112 to the collection device 111. The collection device 111 is located below the collection hopper 110 and is used for collecting or transferring the sampled ore.

[0056] Furthermore, the collection device 111 is an automatic bagging device or a conveyor belt.

[0057] When in use, the device is kept on the movable base of the second platform 107. The material discharged from the guide pipe 112 can be conveyed to the collection device 111 through the collection hopper 110, so that the sampled ore can be automatically collected or transferred to the collection device 111, further ensuring the convenience of remote operation or unmanned automatic operation. The rest of the structure and effect remain unchanged.

[0058] Example 4:

[0059] Compared to the previous embodiments, in this embodiment, the first power source 108 is a lead screw structure, an electric push rod, a hydraulic rod, a linear motor, a motor gear transmission structure, a motor chain transmission structure, or a motor belt transmission structure.

[0060] Furthermore, when the first power source 108 is an electric push rod or a hydraulic rod, the telescopic rod of the electric push rod or hydraulic rod is fixed on the sampling trolley 103, and the electric push rod or hydraulic rod is fixed on the assembly frame 109. The sampling device 1 also includes a protective sleeve 105, which is a foldable plastic film. The protective sleeve 105 is sleeved on the electric push rod or hydraulic rod, and the two ends of the protective sleeve 105 are fixedly connected to the sampling trolley 103 and the electric push rod or hydraulic rod, respectively.

[0061] When in use, ensure that the telescopic rod is clean when the first power source 108 is an electric push rod or a hydraulic rod, to reduce the impact of environmental dust on telescopic movement, while keeping the rest of the structure and effect unchanged.

[0062] Example 5:

[0063] Compared to the previous embodiment, this embodiment also includes elastic baffles 2, enclosures 3, and mounting racks 5. The enclosures 3 are assembled at the end of the conveyor belt 4 where they connect with other equipment. The sampling device 1 is located outside the enclosures 3, and a sampling port is provided through the sampling device 1. The sampling port is arranged along the conveying direction of the conveyor belt 4 and is larger than the movable range of the sampling trolley 103. Elastic baffles 2 are fixed in a row at the bottom of the sampling port and are used to block the sampling port. Mounting racks 5 are assembled outside the enclosures 3 and on the side of the sampling device 1.

[0064] Furthermore, the elastic baffle 2 is made of rubber.

[0065] During use, the enclosure 3 can be used to protect the ore drop point at the tail end of the conveyor belt 4, preventing ore from splashing and injuring people during sampling. Meanwhile, since the top and sides of the elastic baffle 2 are not fixed to the enclosure 3, it will be crushed when the sampling trolley 103 takes samples. After the sampling trolley 103 finishes sampling, the elastic baffle 2 will return to its original position due to its elasticity, ensuring the enclosure 3 is sealed and increasing the safety of the device during use. The mounting frame 5 facilitates the inspection and observation of the device. The rest of the structure and effect remain unchanged.

[0066] Example 6:

[0067] Compared to the previous embodiments, the sampling device 1 in this embodiment also includes a camera 120. The camera 120 is used to observe the material discharge situation at the tail of the conveyor belt 4 and the sampling position of the sampling trolley 103. This allows the device to remotely observe the ore falling situation and the extension position of the sampling trolley 103 through the camera 120 and make remote adjustments, so as to ensure that the sampling trolley 103 can sample normally in a suitable position. The rest of the structure and effect remain unchanged.

[0068] Example 7:

[0069] Compared to the previous embodiments, the sampling device 1 in this embodiment further includes a sensor group 121, which is used to sense the tail discharge position of the conveyor belt 4.

[0070] Furthermore, the sensor group 121 consists of multiple infrared sensors.

[0071] In use, the sensor group 121 can sense the falling of the ore and can also increase the extension position of the sampling trolley 103, thereby facilitating the automatic or remote adjustment of the sampling trolley 103 and ensuring that the sampling trolley 103 can sample normally in the appropriate position. It can be used in conjunction with the camera 120 of Embodiment Six or used alone, with the rest of the structure and effect remaining unchanged.

[0072] Example 8:

[0073] Compared to the previous embodiments, in this embodiment, when the second power source 106 is a lead screw structure, the second power source 106 includes a movable assembly plate 10601, a lead screw 10602, a positioning plate 10603, and a motor 10604. The positioning plate 10603 is fixed on both sides of the second platform 107 along the conveying direction of the conveyor belt 4. The lead screw 10602 is rotatably assembled between the positioning plates 10603. The motor 10604 is used to drive the lead screw 10602 to rotate. The movable assembly plate 10601 is fixed on the first platform 101. The movable assembly plate 10601 covers the lead screw 10602 and is threadedly connected to the lead screw 10602.

[0074] Furthermore, the positioning plate 10603 is used to define the position of the lead screw 10602.

[0075] In use, the motor 10604 drives the lead screw 10602 to rotate, which in turn drives the movable assembly plate 10601 to move, thereby moving the second platform 107 fixed to the movable assembly plate 10601. The assembly range of the second power source 106 can be more concentrated around the second platform 107, reducing the space occupied, while the rest of the structure and effect remain unchanged.

[0076] Example 9:

[0077] Compared to the previous embodiments, the automatic sealing structure 119 described in this embodiment is an electrically controlled cover structure that facilitates automatic or remote control of the unloading port 104 by the device, while the rest of the structure and effects remain unchanged.

[0078] Example 10:

[0079] Compared to the previous embodiments, the automatic capping structure 119 in this embodiment includes a capping groove 11901, a limiting groove 11902, a baffle 11903, a fixing plate 11904, an elastic element 11905, and a push plate 11906. The capping groove 11901 is located at the bottom of the sampling trolley 103 and below the discharge port 104. The capping groove 11901 is larger than the discharge port 104. The capping groove 11901 has limiting grooves on both sides along the moving direction of the sampling trolley 103. The baffle 11903 is slidably mounted in the sealing groove 11901 through the limiting groove 11902. A push plate 11906 is fixed on the side of the baffle 11903 away from the conveyor belt 4. A fixing plate 11904 is fixed on the bottom of the sampling trolley 103 near the side of the conveyor belt 4 adjacent to the push plate 11906. An elastic element 11905 is assembled between the fixing plate 11904 and the push plate 11906. The bottom of the push plate 11906 is lower than the top of the receiving hopper 118.

[0080] Furthermore, the elastic element 11905 is a compression spring.

[0081] During use, when the sampling trolley 103 is about to retract to the designated position, due to height issues, the receiving hopper 118 will block the push plate 11906, causing the push plate 11906 to compress the elastic element 11905 and drive the baffle 11903 to move within the sealing groove 11901, gradually opening the discharge port 104. After the sampling trolley 103 is completely retracted to the designated position, the baffle 11903 completely disengages from the discharge port 104, allowing the discharge port 104 to fully open, so that the sampled ore can fall smoothly into the receiving hopper 118. If the sampled ore is small, it will still fall into the receiving hopper 118 even if the discharge port 104 is not fully open, ensuring accurate dispensing and preventing it from falling outside the receiving hopper 118. When the sampling trolley 103 is sampling, the push plate 11906 gradually moves away from the receiving hopper 118. As a result, the push plate 11906 is affected by the restoring force of the elastic element 11905 and gradually drives the baffle 11903 to close the discharge port 104. When the push plate 11906 is completely separated from the receiving hopper 118, the discharge port 104 is completely closed. This realizes the automatic opening and closing of the discharge port 104 of the mechanical structure, prevents the loss of control of the electric opening and closing, and ensures the stability of the automatic opening and closing of the discharge port 104, that is, ensures the stability of the ore being automatically discharged at a fixed position. Compared with Embodiment 9, it lacks remote controllability. It can be used in combination with Embodiment 9 for the combination of electric control and mechanical structure, or it can be used alone. The rest of the structure and effect remain unchanged.
