[0020] In order to solve the problems existing in the prior art, the utility model provides a fully automatic sampling device, which improves the sampling efficiency and randomness of raw ore and avoids the problems caused by manual sampling.
[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention:
[0022] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of a fully automatic sampling device provided in an embodiment of the present application.
[0023] In this embodiment, the device may include:
[0024] A collecting hopper (1), a material taking shovel (2), a material taking arm (3), a displacement sensor (4), a proximity switch (5), a supporting frame (6), a cycloid reducer (7), a motor (8), and an automatic sampling controller;
[0025] The material picking shovel (2) is welded to the end of the material picking arm (3), the other end of the material picking arm (3) is connected to the output shaft of the cycloid reducer (7), the input shaft of the cycloid reducer (7) is connected to the motor (8), the cycloid reducer (7) and the motor (8) are both connected to the support frame (6) by bolts, the material collecting hopper (1) is welded to one side of the support frame (6), and the support frame (6) is welded to the conveyor frame; the material picking shovel (2) is used to collect materials on the conveyor frame;
[0026] The displacement sensor (4) is arranged on the top surface of the material picking arm (3), and the proximity switch (5) is arranged on a side surface of the support frame close to the material picking arm. The proximity switch (5) and the motor (8) are both connected to the automatic sampling controller, and the automatic sampling controller is used to automatically control the motor to realize the automatic sampling operation.
[0027] It can be seen that, under the control of the automatic sampling controller, the device in this embodiment can collect corresponding materials from the conveyor frame through the material shovel and send the materials to the receiving hopper, so as to realize sampling of the materials on the conveyor.
[0028] Obviously, the fully automatic sampling device in the present application can realize sampling and collection of materials on the conveyor belt during the conveying process. At the same time, the automatic sampling controller is used to realize automatic material sampling in a preset period, which improves the randomness of material sampling, improves the sampling effect, and reduces the interference of sampling environment, manpower and other factors on the test results. In addition, the labor intensity of manual sampling is reduced.
[0029] Optionally, the proximity switch (5) is used to send an electrical instruction when the displacement sensor (4) on the material picking arm (3) approaches the proximity switch (5), so that the material picking arm (3) remains in a preset position when the motor (8) is not working.
[0030] On the basis of this optional solution, the motor in this embodiment is powered on and rotates forward, driving the cycloid reducer to rotate. The material-collecting arm connected to the output shaft of the cycloid reducer completes a circular motion trajectory due to the rotation of the reducer. Because the displacement sensor on the material-collecting arm and the proximity switch on the support frame are used in conjunction, when the motor and the cycloid reducer are paused, the material-collecting arm is always positioned within the set area. After the preset time, the sampling shovel welded at the end of the sampling arm delivers the material to the receiving hopper in a parabolic motion trajectory.
[0031] It can be seen that in this optional solution, the sampling arm is kept at a preset position through the cooperation between the proximity switch and the displacement sensor, so that the sampling arm and the sampling shovel do not affect the normal operation of the conveyor. After the preset time is reached, the material is delivered to the receiving hopper.
[0032] Please refer to Figure 2 , Figure 2 A schematic diagram of a control circuit of a fully automatic sampling device provided in an embodiment of the present application. Figure 2 Among them, QF is the circuit breaker, KM is the contactor, FR is the thermal relay, M is the motor, SB is the start-stop switch, SQ is the proximity switch, KT is the time relay, and HL is the signal light.
[0033] Optionally, the automatic sampling controller includes an automatic control circuit; the automatic control circuit includes: a circuit breaker, a contactor, a thermal relay, a start-stop switch, a time relay, and a signal light; the automatic control circuit is used to control the motor (8) to perform material sampling according to a preset cycle.
[0034] Among them, by setting the time relay, adjusting the power-on delay time of the time relay to set the time period of a single sampling, and then adjusting the power-off delay time of the time relay according to the time it takes for the material-grabbing arm to swing back and forth once. The sampling speed can be determined according to the length of the interval period of the material-grabbing arm swing. The sampling speed is not specifically limited here and can be adjusted according to the actual needs of the site.
[0035] like Figure 2 , turn on the power, adjust the power-on delay time of the time relay to set the interval period of a single sampling, set it at 60 seconds according to the production and testing requirements of the workshop, and then adjust the power-off delay time of the time relay according to the time required for the sampling arm to swing one circle. Turn the switch to the automatic position, the time relay starts timing, and the sampler starts working when the set time is reached, and stops when the power-off delay time is reached. At the same time, the time relay starts timing again and cycles to the next working state.
[0036] When the switch is turned on, it is in automatic mode, the digital display time relay coil is energized, and when the set sampling cycle time is reached, the normally open contact of the time relay is closed, the contactor coil is energized, and the main contact is closed. When the set sampling time is reached, the normally closed contact of the time relay is disconnected, the contactor coil is de-energized, the main contact is disconnected, and the motor stops running.
[0037] Optionally, the reclaiming shovel (2) is welded with a leak-proof enclosure.
[0038] It can be seen that in this optional solution, leak-proof enclosures are used to avoid the problem of material leakage during the delivery process.
[0039] Optionally, a stirring device is provided in the receiving hopper (1) for mixing materials.
[0040] It can be seen that in this optional solution, a stirring device is provided in the receiving hopper (1), which can improve the efficiency of mixing materials. The stirring device can be any stirring device provided by the prior art.
[0041] Optionally, a volume recognition device is provided in the receiving hopper (1) for sending an alarm signal when the volume of the material in the receiving hopper (1) is greater than a preset volume.
[0042] It can be seen that in this optional solution, the receiving hopper is provided with a volume recognition device, which can identify the volume of the material in the receiving hopper, so that when the material volume is greater than the preset volume, an alarm signal is sent to promptly remind the operator to perform subsequent operations.
[0043] Optionally, the material shovel (2) is a material shovel with adjustable area.
[0044] The sampling shovel is welded on the sampling arm. The area of the sampling shovel determines the amount of single sampling. According to the working environment, technical requirements, and work intensity of the sampling, the thickness and size of the sampling shovel can be adjusted to ensure the reliability of the sampling shovel for long-term use.
[0045] The fully automatic sampling device in the embodiment of the present application is further described below through another specific embodiment.
[0046] The operation purpose in this embodiment is that the raw ore (carnallite) needs to be sampled and analyzed on the conveyor belt before entering the crystallization unit equipment.
[0047] The implementation preparation of this embodiment may include:
[0048] Equipment preparation: Prepare a fully automatic sampling device, including a receiving hopper, a picking shovel, a picking arm, a displacement sensor, a proximity switch, a support frame, a cycloid reducer, a motor and an automatic sampling controller.
[0049] Environmental layout: The supporting frame of the fully automatic sampling device is welded to the conveyor frame to ensure the stable operation of the sampler.
[0050] Parameter setting: According to production requirements, set the power-on delay time of the time relay to determine the time period of a single sampling, for example, set it to 60 seconds.
[0051] The implementation steps of this embodiment may include:
[0052] Step 1, installation and debugging:
[0053] Install the fully automatic sampling device and ensure that all parts are correctly connected and fixed to the conveyor frame. Adjust the displacement sensor and proximity switch to ensure that the material arm can be accurately positioned when not in operation.
[0054] Step 2, automatic control settings:
[0055] According to the production and testing requirements, the sampling cycle and power-off delay time are set through the time relay. Configure the automatic control circuit, including circuit breakers, contactors, thermal relays, etc., to ensure that the automatic sampling controller can control the motor according to the preset cycle.
[0056] Step 3, sampling operation:
[0057] Start the automatic sampling controller, the motor is powered on and rotates forward, driving the cycloid reducer to rotate, and the material picking arm completes a circular motion trajectory. The picking shovel on the picking arm collects the material along the set trajectory and sends the material to the receiving hopper.
[0058] Step 4, material handling:
[0059] The materials are mixed and stored in the receiving hopper, and a stirring device can be used to improve the mixing efficiency. If the volume of the materials in the receiving hopper exceeds a preset value, the volume recognition device sends an alarm signal.
[0060] Step 5, analysis and testing:
[0061] Analyze and test the materials in the receiving hopper.
[0062] It can be seen that after the full-automatic sampling device is used in this embodiment, the sampling process is automated, which significantly reduces the labor intensity of manual sampling. The randomness and efficiency of sampling are improved, and the interference of environmental and human factors on the test results is reduced. Through the design of the automatic control circuit, the sampler can operate stably, ensuring the continuity and consistency of sampling.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be covered by the protection scope of the utility model.
