[0002] Mineral resource mining is not only an important foundation for industrial development, but also one of the key drivers of economic growth and social development. Mined ore is usually stored in a mine yard and needs to be transported before it can enter the factory for further processing. Ore sampling and testing is an important production work in the mining process. On the one hand, the test grade of the collected samples can be used to objectively evaluate the current geology, mining, and mineral processing work. On the other hand, it also has important guiding significance for the next step of mining and beneficiation work planning. Since manual sampling is easily affected by human subjective consciousness such as experience and preferences, the representativeness of the extracted samples is poor, the test results are inaccurate, and the accuracy of the evaluation of the current mining and beneficiation work is seriously affected. Therefore, the main method of mineral processing is machine selection.

[0003] When existing equipment is sampling ore, the sampling component is prone to rigid compression contact with the ore, which can easily cause damage to the sampling component or ore crushing. In addition, the ore is usually piled directly on the conveyor belt, which causes the sampling component to move the ore during sampling, causing the ore to fall out of the conveyor belt.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Embodiment 1:

[0024] This embodiment provides a fully automatic sampling device for mineral processing in mines, specifically Figure 1 , Figure 2 As shown, it includes a transport rack 101, a sampling rack 102, and a sampling box 104. The sampling rack 102 is installed on the sampling rack 102. A guide component is installed on the sampling rack 102. A telescopic component is arranged on the guide component. A sampling component 2 is arranged on the telescopic component.

[0025] like Figure 6 As shown, the sampling assembly 2 includes a sampling shell 201, a clamping motor 203, and a toggle motor 204. The clamping motor 203 and the toggle motor 204 are installed on the sampling shell 201. The sampling shell 201 is rotatably connected to a transmission shaft 213, and a slidingly connected ring gear shaft 207 and a fixedly connected clamping seat 208 are installed on the transmission shaft 213. The clamping seat 208 is rotatably connected to a double-section lead screw 214 and is slidably connected to two mirror-image-arranged sampling claws 202. The sampling claws 202 are threadedly connected to the double-section lead screw 214, and a fourth gear 215 is installed on the double-section lead screw 214, and the fourth gear 215 is meshed with the ring gear shaft 207; the clamping motor 203 is transmission-connected to the ring gear shaft 207, and the toggle motor 204 is transmission-connected to the transmission shaft 213.

[0026] When the sampling box 104 is in the sampling area, the guide assembly moves the telescopic assembly and the sampling assembly 2 to the top of the sampling box 104. At this time, the telescopic assembly drives the sampling assembly 2 to extend, so that the sampling assembly 2 contacts the ore in the sampling box 104. At the same time, the toggle motor 204 is started, driving the transmission shaft 213 to rotate, and the transmission shaft 213 drives the clamping seat 208 to rotate. When the clamping seat 208 rotates, the two sampling claws 202 also start to rotate. The rotation of the sampling claws 202 can toggle the ore in the sampling box 104 to prevent the ore from being sampled. The sample claw 202 is in rigid compression contact with the ore, and then the clamping motor 203 is started, and the clamping motor 203 drives the ring gear shaft 207 to move longitudinally, and the ring gear shaft 207 movably drives the fourth gear 215 to rotate, and the fourth gear 215 drives the double-section lead screw 214 to rotate. Since the two sections of threads set on the double-section lead screw 214 have opposite rotation directions, the two sampling claws 202 are close to each other at this time to clamp part of the ore, and then the sampling component 2 is reset under the joint action of the telescopic component and the guide component to complete a sampling.

[0027] Through the above arrangement, when sampling the ore, the sampling claw 202 can be prevented from being rigidly squeezed with the ore, which can prevent the ore from being broken on the one hand; on the other hand, the sampling claw 202 can be protected to reduce its damage.

[0028] Embodiment 2:

[0029] This embodiment further expands the sampling component 2 on the basis of the embodiment 1. Figures 4 - 6 As shown, the toggle motor 204 is provided with a first gear 209, the transmission shaft 213 is provided with a second gear 210, and the second gear 210 is meshed with the first gear 209; the clamping motor 203 is provided with a worm 205, the sampling housing 201 is rotatably connected to an intermediate shaft 206, a worm wheel 211 and a third gear 212 are provided on the intermediate shaft 206, the worm wheel 211 is meshed with the worm 205, and the third gear 212 is meshed with the ring gear shaft 207.

[0030] When the clamping motor 203 is started, the clamping motor 203 drives the worm 205 to rotate, the worm 205 drives the worm wheel 211 to rotate, the worm wheel 211 drives the third gear 212 to rotate through the intermediate shaft 206, and the third gear 212 drives the ring gear shaft 207 to move longitudinally; when the toggle motor 204 is started, the toggle motor 204 drives the first gear 209 to rotate, the first gear 209 drives the second gear 210 to rotate, and the second gear 210 drives the transmission shaft 213 to rotate.

[0031] Through the above arrangement, the clamping motor 203 and the toggle motor 204 can be arranged together, which can effectively reduce the width of the sampling shell 201, that is, reduce its cross-sectional area, thereby increasing the distribution area of the sampling points and facilitating the layout of the power cables.

[0032] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0033] Embodiment 3:

[0034] This embodiment further expands the telescopic component on the basis of embodiment 1. Figure 3 As shown, the telescopic assembly includes a guide motor 111, one end of the guide motor 111 is connected to the sampling shell 201, and the other end is connected to the guide assembly.

[0035] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0036] Embodiment 4:

[0037] This embodiment further expands the guide component on the basis of embodiment 1. Figure 3 As shown, the guide assembly includes a guide shaft 109, a transfer shaft 110, and a transverse slider 106. The guide shaft 109 and the transfer shaft 110 are both rotatably connected to the sampling rack 102. The transverse slider 106 is slidably connected to the guide shaft 109 and threadedly connected to the transfer shaft 110. A guide motor 111 is installed on the sampling rack 102, the guide motor 111 is connected to the transfer shaft 110, and the transverse slider 106 is connected to the telescopic assembly.

[0038] When the guide motor 111 is started, the transfer shaft 110 is driven to rotate. At this time, the transverse slider 106 begins to slide horizontally, driving the telescopic component and the sampling component 2 to move. The guide motor 111 is controlled by the control system. When the sampling component 2 is above the sampling box 104, the guide motor 111 will also drive the sampling component 2 to move, but the moving distance is random, so that the sampling component 2 can randomly sample in different areas of the sampling box 104. The control system is a commercially available product, and the specific model is adaptively selected by technicians in this field and will not be repeated here.

[0039] The other parts of this embodiment are the same as those of the above embodiment, and will not be described in detail.

A transport belt 103 is sleeved on the conveying roller 108. The sampling box 104 is placed on the transport belt 103. A weighing device 107 is installed on the transport rack 101.

[0042] The transport belt 103 drives the sampling box 104 to move, thereby transferring the ore from the ore yard to the factory area. At the same time, the sampling box 104 will pass by the weighing device 107 during the transfer. The weighing device 107 is used to weigh the ore in the sampling box 104 to prevent overloading.

[0043] The other parts of this embodiment are the same as those of the above embodiment, and will not be described in detail.

[0044] Embodiment 6:

[0045] This embodiment is further extended on the basis of Embodiment 1, specifically as Figure 1 shown. A sample collection box 105 is installed on the transport rack 101.

[0046] Each time the sampling component 2 takes a sample, the sample will be stored in the sample collection box 105. There is no need for personnel to collect it each time. After multiple random samplings, the sample in the sample collection box 105 can be taken away for analysis.

[0047] The other parts of this embodiment are the same as those of the above embodiment, and will not be described in detail.
