Abstract
Description
Technical Field
[0001] This application relates to the field of feed sampling devices, and more particularly to an automatic sample retention device. Background Technology
[0002] Feed sampling and testing are essential procedures during the packaging and shipping process. Currently, sampling primarily involves manually selecting samples from pre-packaged feed at random.
[0003] Manual sampling is a cumbersome process, which increases the workload for staff. Furthermore, the concentrated nature of manual sampling results in samples that are not representative enough, thus reducing the accuracy of the sampling and testing results. Utility Model Content
[0004] To address the aforementioned technical problems, this application provides an automatic sample retention device.
[0005] This application provides an automatic sample retention device, which adopts the following technical solution:
[0006] An automatic sample retention device includes a sampling cylinder inclined through a feed tube, a sampling port on the sampling cylinder, a cover plate for sealing the sampling port, a drive mechanism for moving the cover plate, a control mechanism, and a collection box for collecting samples; the cover plate has an arc-shaped structure and is slidably connected to the sampling cylinder; the top of the sampling cylinder has a sealed structure, the bottom of the sampling cylinder has a discharge port, and the collection box is located below the discharge port.
[0007] By adopting the above technical solution, automatic sampling is achieved, greatly improving sampling efficiency. The inclined design of the sampling cylinder penetrating the feed pipe makes the sampling position more reasonable and improves the representativeness of the samples. The arc-shaped cover plate slides and connects with the sampling cylinder, effectively sealing the sampling port and preventing material leakage when sampling is not needed. The sealing structure at the top of the sampling cylinder and the discharge port design at the bottom, together with the collection box located below the discharge port, ensure the smooth collection and storage of samples.
[0008] Preferably, the driving mechanism includes an electric telescopic rod disposed at the top of the sampling cylinder, and the electric telescopic rod is connected to the cover plate.
[0009] By adopting the above technical solution, the electric telescopic rod is set at the top of the sampling cylinder and connected to the cover plate, which can realize the automatic opening and closing of the cover plate, thereby replacing manual operation, improving sampling efficiency, and reducing the labor intensity of staff.
[0010] Preferably, a positioning block is provided inside the sampling tube. The positioning block is located at the end of the sampling port away from the electric telescopic rod, and the positioning block is used to limit the cover plate.
[0011] By adopting the above technical solution, the positioning block can limit the movement of the cover plate, ensuring the accuracy of the cover plate's position when opening or closing the sampling port, thereby improving the stability of sampling. The electric telescopic rod drives the cover plate to move, and the positioning block further optimizes the movement trajectory of the cover plate, preventing excessive movement that could cause the sampling port to fail to open or close completely, thus improving the reliability of the device.
[0012] Preferably, the top of the sampling cylinder is provided with a clearing mechanism, which includes a compressed gas storage tank, a gas supply pipe communicating with the compressed gas storage tank, and a pulse valve provided on the gas supply pipe. The end of the gas supply pipe away from the compressed gas storage tank is connected to the top of the sampling cylinder, and the pulse valve is provided at the end of the gas supply pipe near the sampling cylinder.
[0013] By adopting the above technical solutions, the unblocking mechanism can effectively reduce blockages during sampling and improve sampling smoothness. The combination of the compressed gas storage tank and the gas delivery pipe can deliver compressed gas into the sampling cylinder when needed, while the pulse valve can precisely control the timing and flow rate of gas release, thereby achieving the unblocking effect inside the sampling cylinder.
[0014] Preferably, there are multiple gas delivery pipes and multiple pulse valves, and the multiple gas delivery pipes are arranged in a circumferential array at the top of the sampling cylinder.
[0015] By adopting the above technical solution, multiple gas supply pipes and pulse valves are arranged in a circumferential array at the top of the sampling cylinder, which can deliver compressed gas into the sampling cylinder from multiple directions, further enhancing the unblocking effect, effectively reducing the occurrence of blockage during the sampling process, and thus improving the smoothness of sampling.
[0016] Preferably, the control mechanism includes a controller and a timer, the controller being electrically connected to the timer and the electric telescopic pole.
[0017] By adopting the above technical solution, automatic control of the sampling process is achieved. The electrical connection between the controller and the timer enables precise control of the sampling time, ensuring the timed start and stop of the sampling operation, thereby improving the efficiency and accuracy of sampling. The electrical connection between the controller and the electric telescopic rod enables the automatic opening and closing of the cover, reducing manual intervention and lowering the labor intensity of workers.
[0018] Preferably, a conveyor belt is provided below the collection box, and the conveyor belt is electrically connected to the controller.
[0019] By adopting the above technical solution, automated sample transport was achieved. The controller can control the operation of the conveyor belt, thereby automatically transporting the sample in the collection box to the designated location after sampling, effectively reducing the labor intensity of staff and further improving sampling efficiency.
[0020] Preferably, an infrared detector is provided at one end of the sampling cylinder near the discharge port, and the infrared detector is electrically connected to the controller.
[0021] By adopting the above technical solution, intelligent monitoring of the sampling process is achieved. The infrared detector can detect when the collection box is conveyed to the outlet via the conveyor belt, ensuring the accuracy and smoothness of the sampling process, thereby effectively improving the efficiency and reliability of sampling.
[0022] In summary, this application has the following beneficial technical effects:
[0023] 1. By setting a sampling tube and a movable cover plate in the feed pipe, automatic sampling is achieved, which improves sampling efficiency and ensures that the sample is highly representative.
[0024] 2. A dredging mechanism is set up, which uses a compressed gas storage tank and a pulse valve to periodically deliver gas into the sampling cylinder, effectively reducing the occurrence of blockages during the sampling process and improving the smoothness of sampling;
[0025] 3. By combining the control mechanism and the conveyor belt, the sampling time and sample transportation process can be precisely controlled, reducing the labor intensity of the staff and further improving the degree of automation in sampling. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0031] This application discloses an automatic sample retention device.
[0032] Reference Figure 1 , Figure 2 and Figure 3 An automatic sampling device includes a sampling cylinder 2 inclined through a feed pipe 1, a sampling port 21 on the sampling cylinder 2, a cover plate 22 for sealing the sampling port 21, a drive mechanism 23 for moving the cover plate 22, a control mechanism 3, and a collection box 4 for collecting samples. The sampling cylinder 2 is fixedly connected to the feed pipe 1. The feed pipe 1 is used to transport feed before packaging. The cover plate 22 has an arc-shaped structure and is slidably connected to the sampling cylinder 2. The top of the sampling cylinder 2 is sealed, and the bottom of the sampling cylinder 2 has a discharge port 24, with the collection box 4 located below the discharge port 24. A clearing mechanism 5 is provided at the top of the sampling cylinder 2.
[0033] The drive mechanism 23 includes an electric telescopic rod 231 fixedly installed on the top of the sampling cylinder 2, and the electric telescopic rod 231 is fixedly connected to the cover plate 22.
[0034] A positioning block 25 is fixedly installed inside the sampling cylinder 2. The positioning block 25 is located at the end of the sampling port 21 away from the electric telescopic rod 231. The positioning block 25 is used to limit the cover plate 22. When the cover plate 22 blocks the sampling port 21, the end of the cover plate 22 away from the electric telescopic rod 231 abuts against the positioning block 25.
[0035] The unblocking mechanism 5 includes a compressed gas storage tank 51, a gas supply pipe 52 fixedly connected to the compressed gas storage tank 51, and a pulse valve 53 fixedly installed on the gas supply pipe 52. The end of the gas supply pipe 52 away from the compressed gas storage tank 51 is fixedly connected to the top of the sampling cylinder 2, and the pulse valve 53 is located at the end of the gas supply pipe 52 near the sampling cylinder 2. An air inlet pipe 511 is fixedly installed at the bottom of the compressed gas storage tank 51, and an air inlet valve 512 is fixedly installed on the air inlet pipe 511. Compressed gas is supplied to the compressed gas storage tank 51 through the air inlet pipe 511 and the air inlet valve 512.
[0036] There are two gas supply pipes 52 and two pulse valves 53. The two gas supply pipes 52 are arranged in a circular array at the top of the sampling cylinder 2.
[0037] The control mechanism 3 includes a controller 31 and a timer 32. The controller 31 is electrically connected to the timer 32 and to the electric telescopic rod 231. The timer 32 and the controller 31 control the movement of the electric telescopic rod 231, so that the cover plate 22 closes after a certain sampling time and opens after a certain interval to take samples, so that the sampled samples are representative.
[0038] A conveyor belt 6 is installed below the collection box 4, and the conveyor belt 6 is electrically connected to the controller 31. The conveyor belt 6 transports the collection box 4 to below the discharge port 24 for automatic sampling, and transports the collected collection box 4 to a designated location for centralized collection and storage of the sampled samples.
[0039] An infrared detector 7 is fixedly installed at one end of the sampling cylinder 2 near the discharge port 24. The infrared detector 7 is electrically connected to the controller 31. The infrared detector is used to detect the position of the collection box. When the collection box reaches below the discharge port 24, the controller 31 receives a signal from the infrared detector, which facilitates the control of the electric telescopic rod 231 to move the cover plate 22 above the sampling port 21, and then automatically sample through the sampling port 21.
[0040] The implementation principle of the automatic sampling device in this application embodiment is as follows: The inclined sampling cylinder 2 and the arc-shaped cover plate 22 enable precise opening and closing of the sampling port 21, ensuring sample representativeness. The cooperation of the electric telescopic rod 231 and the positioning block 25 improves the stability and reliability of the cover plate 22's movement. The combination of the compressed gas storage tank 51 and the pulse valve 53 effectively reduces blockage during sampling. The coordinated operation of the controller 31 and the timer 32 achieves automation and periodicity of the sampling process, significantly improving sampling efficiency and representativeness. Automated sampling greatly improves sampling efficiency and reduces the labor intensity of workers, and ensures representative samples, thereby improving the accuracy of sampling and testing results.
[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
