Description

Technical Field

[0001] The utility model relates to the technical field of material handling, in particular to a positioning and sampling device for a chute. Background Technique

[0002] A chute is an open channel for self-flow transportation of ore and rock excavated using the terrain. It is usually a trough on the ground that transports things from a high place to a low place, with a smooth inner surface to allow things to slide down automatically, such as a sluice for washing gold-bearing ore sand or an inclined flume for floating logs. It is mainly applied to small open-pit mines. In large and medium-sized open-pit mines, chutes are often connected in series with ore passes and can be set within the stope range or outside it.

[0003] The patent with the patent announcement number CN221350760U discloses a coal washing chute sampling device, including an inclined slide rail and a sampling trough. The slide rail is installed on a bracket, and the sampling trough is slidably installed on the slide rail along the length direction. The end of the sampling trough is inclined upward and extends into the chute from the sampling port; a receiving box is arranged below the sampling port; a driving mechanism for driving the sampling trough to reciprocate is installed on the bracket; a fixed frame is fixedly arranged at the upper end of the slide rail, and a baffle fixedly arranged on the fixed frame is slidably arranged close to the inner wall of the sampling trough; a scraping mechanism is further arranged on the fixed frame, and the scraping mechanism includes a scraping plate, a push rod, a connecting rod, a rotating shaft and a motor. The rotating shaft on the fixed frame is connected to the power of the motor, one end of the rotating rod is vertically movably sleeved on the rotating shaft, a blocking block is fixedly arranged in the middle of the rotating rod, the other end of the rotating rod is rotatably connected to the upper end of the connecting rod, and the lower end of the connecting rod is rotatably connected to the upper end of the push rod. The push rod is vertically slidably installed on the fixed frame.

[0004] For the coal washing chute sampling device designed in the above patent, when the first cylinder extends upward, it can drive the sampling trough to extend upward into the chute to collect coal samples. As the first cylinder shortens and drives the sampling trough to reset, under the action of the baffle, the coal samples in the sampling trough can be pushed outwards and fall into the receiving box for collection. Due to the lack of a sampling depth adjustment function, this device may be difficult to cope with the change in the thickness of the material layer in the chute. Especially when dealing with materials of different particle sizes or different densities, the fixed sampling depth may lead to inaccurate sampling, thus affecting the representativeness and accuracy of sampling. Therefore, it is necessary to improve the sampling accuracy and design a positioning and sampling device for a chute. Content of the Utility Model

[0005] In order to overcome the drawback that when the existing chute sampling device conducts unified sampling at the same position, the representativeness and accuracy of sampling will be low, a positioning and sampling device for a chute with adjustable sampling is provided.

[0006] The technical solution is as follows: A positioning and sampling device for a chute, comprising a mounting end, a linear motor, a first connecting plate, a sampling cylinder, a servo motor, a discharge cylinder, and a spiral feeding blade. The linear motor is mounted on the mounting end. The linear motor is mounted with a first connecting plate through a mover seat. A servo motor is mounted on the top of the first connecting plate. The middle part of the first connecting plate is fixedly connected with a sampling cylinder through a bracket. One side of the sampling cylinder is communicated with a discharge cylinder through an opening. The discharge port of the discharge cylinder is inclined downward. A spiral feeding blade is rotatably mounted inside the sampling cylinder. The output shaft of the servo motor penetrates through the top of the sampling cylinder and is connected to the rotating shaft of the spiral feeding blade. The linear motor drives the sampling cylinder to move up and down through the first connecting plate for sampling, and drives the spiral feeding blade to rotate upward for feeding, so that the sampling depth of the sampling tube can be adjusted.

[0007] Further, a notch is opened on one side of the lower sampling pipe orifice of the sampling cylinder, and the spiral feeding blade is replaceably mounted in the sampling cylinder, and spiral feeding blades of different sizes can be selected and mounted in the sampling cylinder according to the actual sampling requirements of the material.

[0008] Further, the mounting end includes a frame, a bearing, a mounting plate, a cylinder, a second connecting plate, and an adjusting member. The frame is the mounting carrier of this device. The frame is composed of a bottom plate and columns. The mounting plate is rotatably mounted on the columns of the frame through bearings. A cylinder is fixedly connected to the top of the mounting plate. A second connecting plate is connected to the telescopic rod of the cylinder. A linear motor is mounted on the second connecting plate. The positions of the second connecting plate and the linear motor are perpendicular to each other. The telescopic rod of the cylinder drives the linear motor to move horizontally through the second connecting plate, so that the sampling cylinder driven by the linear motor can perform fixed-point sampling at different positions. An adjusting member is mounted on the bottom plate of the frame. The adjusting member is used to support and rotate and adjust components such as the mounting plate and the cylinder.

[0009] Further, a chute frame is provided on the mounting plate. The chute frame is fixedly connected to the bottom side of the mounting plate. Two symmetric chutes are opened on the chute frame. The chute frame is used to adapt to the adjusting member to rotate and adjust the mounting plate.

[0010] Further, the adjusting member includes a sliding rod, a lifting plate, a guide rod, a screw rod, and a support plate. The chute frame is slidably connected with the sliding rod through the chute on it. The sliding rod is fixedly connected with a lifting plate. The lifting plate is an L-shaped plate. A guide rod is fixedly connected to the bottom plate of the frame. The guide rod slidably penetrates through the lifting plate. A support plate is fixedly mounted on the column of the frame. A screw rod is rotatably mounted on the bottom surface of the end of the support plate. The screw rod is threadedly connected with the lifting plate. The screw rod drives the lifting plate to move up and down threadedly, and the lifting plate can adjust the rotation angle of the entire mounting plate and the cylinder up and down.

[0011] Furthermore, it also includes a motor which is installed on the bottom plate of the frame. The output shaft of the motor is connected to the lead screw. By driving the lead screw to rotate through the motor, the lead screw can automatically drive the lifting plate to move up and down.

[0012] The beneficial effects are as follows: 1. The utility model drives the sampling cylinder to move up and down through the linear motor, which can accurately control the sampling depth, ensure the consistency of the sampling position each time, thereby improving the sampling accuracy. At the same time, the spiral feeding blades in the sampling cylinder can be replaced with different sizes according to the actual sampling requirements, flexibly adapting to materials with different particle sizes or densities, and improving the applicability and efficiency of sampling.

[0013] 2. In the design of the installation end of the utility model, the second connecting plate is driven to move horizontally through the cylinder, so that the sampling cylinder can perform fixed-point sampling at different chute positions, enhancing the flexibility and adaptability of the device. Through the design of the adjusting member, the installation plate, the cylinder and other components are allowed to be adjusted in angle. Through the cooperation of the sliding rod, the lifting plate, the guide rod, the lead screw and the support plate, the sampling position can be accurately adjusted to meet the sampling requirements of different chutes.

[0014] 3. The utility model can also drive the lifting plate to move up and down automatically through the connection between the motor and the lead screw, so as to automatically adjust the angle of the whole device without manual intervention, realizing automatic operation. The spiral feeding blades are driven to rotate upward for material taking through the servo motor, automatically completing the processes of sampling and feeding, further improving the degree of automation of the operation and reducing the labor intensity of the operator.

DETAILED DESCRIPTION OF THE INVENTION

[0020] The present utility model will be specifically described below in conjunction with the accompanying drawings.

[0021] Embodiment: A positioning and sampling device for a chute, as Figure 1 and Figure 2 shown, includes an installation end, a linear motor 1, a first connecting plate 2, a sampling cylinder 3, a servo motor 4, a discharge cylinder 5, and a spiral feeding blade 6. The linear motor 1 is installed on the installation end. The linear motor 1 is installed with the first connecting plate 2 through a mover seat. The top of the first connecting plate 2 is installed with a servo motor 4. The middle of the first connecting plate 2 is fixedly connected with a sampling cylinder 3 through a bracket. One side of the sampling cylinder 3 is communicated with the discharge cylinder 5 through an opening. The discharge port of the discharge cylinder 5 is inclined downward. A spiral feeding blade 6 is rotatably installed inside the sampling cylinder 3. The output shaft of the servo motor 4 penetrates through the top of the sampling cylinder 3 and is connected to the rotating shaft of the spiral feeding blade 6. The linear motor 1 drives the sampling cylinder 3 to move up and down through the first connecting plate 2 for sampling, and drives the spiral feeding blade 6 to rotate upward for feeding through the servo motor 4, so that the sampling depth of the sampling tube can be adjusted. A notch is opened on one side of the lower sampling pipe orifice of the sampling cylinder 3, and the spiral feeding blade 6 is replaceably installed in the sampling cylinder 3, and the spiral feeding blade 6 of different sizes can be selected and installed in the sampling cylinder 3 according to the actual sampling requirements of the material.

[0022] As Figure 1 , Figure 3 and 4 shown, the installation end includes a frame 7, a bearing 11, a mounting plate 8, a cylinder 9, a second connecting plate 10, and an adjusting member. The frame 7 is the installation carrier of the device. The frame 7 is composed of a bottom plate and a support column. The mounting plate 8 is rotatably installed on the support column of the frame 7 through the bearing 11. The top of the mounting plate 8 is fixedly connected with a cylinder 9. The telescopic rod of the cylinder 9 is connected with a second connecting plate 10. The linear motor 1 is installed on the second connecting plate 10. The positions of the second connecting plate 10 and the linear motor 1 are perpendicular to each other. The telescopic rod of the cylinder 9 drives the linear motor 1 to move horizontally through the second connecting plate 10, so that the sampling cylinder 3 driven by the linear motor 1 can perform fixed-point sampling at different positions. An adjusting member is installed on the bottom plate of the frame 7. The adjusting member is used to support and rotate and adjust components such as the mounting plate 8 and the cylinder 9; a chute frame 12 is provided on the mounting plate 8. The chute frame 12 is fixedly connected to the bottom side of the mounting plate 8. Two symmetrical chutes are opened on the chute frame 12. The chute frame 12 is used to adapt to the adjusting member to rotate and adjust the mounting plate 8.

[0023] As Figure 1 and Figure 4As shown, the adjusting member includes a sliding rod 13, a lifting plate 14, a guide rod 15, a lead screw 16, and a support plate 17. The sliding rod 13 is slidably connected to the chute frame 12 through the chute thereon. The lifting plate 14 is fixedly connected to the sliding rod 13. The lifting plate 14 is an L-shaped plate. The guide rod 15 is fixedly connected to the bottom plate of the frame 7. The guide rod 15 slidably penetrates the lifting plate 14. The support plate 17 is fixedly installed on the pillar of the frame 7. The lead screw 16 is rotatably installed on the bottom surface of the end of the support plate 17. The lead screw 16 is threadedly connected to the lifting plate 14. The lead screw 16 drives the lifting plate 14 to lift and lower, and the lifting plate 14 can adjust the rotation angle of the entire mounting plate 8 and the cylinder 9 up and down.

[0024] As Figure 4 shown, it further includes a motor 18. The motor 18 is also installed on the bottom plate of the frame 7. The output shaft of the motor 18 is connected to the lead screw 16. By driving the lead screw 16 to rotate through the motor 18, the lead screw 16 can automatically drive the lifting plate 14 to lift and lower.

[0025] When using this device to take samples on the chute, first install this sampling device at the sampling position of the chute. According to the inclination direction of the chute, the user controls and activates the motor 18. The motor 18 will drive the lead screw 16 to rotate through the output shaft. The rotating lead screw 16 will drive the lifting plate 14 to lift and lower through the thread. The lifting plate 14 will vertically lift and lower under the guiding action of the guide rod 15. The lifting and lowering lifting plate 14 will act on the chute frame 12 through the sliding rod 13, so that the pressed chute frame 12 will drive the mounting plate 8 to rotate. The mounting plate 8 will rotate around the bearing 11 as the axis. When the mounting plate 8 rotates, since the sliding rod 13 will move within the chute frame 12 and is always limited within the chute frame 12, the rotating mounting plate 8 can maintain the rotation angle. When the mounting plate 8 rotates, it will synchronously drive the cylinder 9 to rotate, and then drive the second connecting plate 10 and the linear motor 1 mounted thereon to rotate through the cylinder 9. When the mounting plate 8 and the cylinder 9 rotate to be parallel to the chute, the linear motor 1, the servo motor 4, the sampling cylinder 3, etc. can be rotated to always be perpendicular to the sliding surface of the chute. After activating the linear motor 1, the linear motor 1 drives the first connecting plate 2 to descend through the mover seat. The descending first connecting plate 2 will synchronously drive the sampling cylinder 3 and the servo motor 4 to vertically descend to the material sampling position on the chute. According to the depth of the sample to be taken, the lifting position of the sampling cylinder 3 can be adjusted by controlling the mover seat of the linear motor 1. At this time, activate the servo motor 4. The output shaft of the servo motor 4 will drive the spiral feeding blade 6 to rotate within the sampling cylinder 3. When the lower sampling port of the sampling cylinder 3 touches the material, the rotating spiral feeding blade 6 will continuously rotate the material at the sampling port into the sampling cylinder 3. When the material in the sampling cylinder 3 is transported to the position of the discharge cylinder 5 by the spiral feeding blade 6, the sampled material will slide out from the discharge cylinder 5 for the user to collect and detect. When it is necessary to change the position for sampling on the chute, the position of the linear motor 1 can be driven and adjusted by the cylinder 9. And after each adjustment of the position, the sampling cylinder 3 is driven to lift and lower by the linear motor 1, so that various depths of sampling can be realized for the materials at different positions, improving the application range and practicability of this sampling device.
