[0024] Please see Figures 1-5 As shown in the embodiment of this utility model, an automatic sampling device for a shipping conveyor belt includes a frame 1, a transport belt 2 is arranged above the frame 1, a sampling frame 3 is arranged above the frame 1, an electric slide rail 4 is arranged on the sampling frame 3, an electric slider 41 is slidably connected to the electric slide rail 4, an installation platform 5 is slidably connected to the electric slider 41, a drive mechanism 6 is arranged on the installation platform 5, a sampling hopper 7 is fixedly connected below the drive mechanism 6, an opening and closing component 8 is arranged at the bottom of the sampling hopper 7, and a feeding mechanism 9 is also arranged on one side above the frame 1.

[0025] The frame 1 serves as the overall support frame, fixing all components. The conveyor belt 2 is used to transport materials. The sampling frame 3 is fixed above the frame 1, providing support for the entire sampling mechanism. An electric slide rail 4 is mounted on the sampling frame 3, driving the electric slider 41 to move the sampling hopper 7 horizontally. The mounting platform 5 is slidably connected to the electric slide rail 4, serving as the mounting base for the drive mechanism 6. The drive mechanism 6 is mounted on the mounting platform and is responsible for driving the sampling hopper 7 to rotate. The sampling hopper 7 collects materials from the conveyor belt 2. An opening and closing assembly 8 is located at the bottom, controlling the opening and closing of the bottom of the sampling hopper 7 to achieve precise material discharge. The feeding mechanism 9 receives the material released from the sampling hopper 7 and transports it to the laboratory or storage container.

[0026] The sampling frame 3 is fixed above the frame 1 and supports the entire sampling mechanism. The electric slide rail 4 provides horizontal movement, enabling the sampling bucket 7 to move accurately above the conveyor belt 2 and to move to the unloading mechanism 9 after sampling. The electric slider 41 is mounted on the electric slide rail 4 and can slide along the electric slide rail 4. The mounting platform 5 is fixed on the electric slider 41 and moves with the electric slider 41.

[0027] The driving mechanism 6 is arranged on the mounting platform 5 and is connected with the sampling bucket 7, and is responsible for driving the sampling bucket 7 to rotate. When the sampling bucket 7 moves to the position directly above the conveying belt 2, the driving mechanism 6 is started to drive the sampling bucket 7 to rotate. After the sampling bucket 7 rotates for one circle, the material is collected, the sampling is completed, and the sampled material is transported. After the sampling bucket 7 is filled with the material, the electric sliding block 41 moves along the electric sliding rail 4 to bring the sampling bucket 7 to the position above the discharging mechanism 9. The opening and closing assembly 8 is responsible for controlling the opening and closing of the sampling bucket 7 to ensure that the material can be accurately discharged into the discharging mechanism 9 without spilling outside. After the discharging mechanism 9 receives the material, the material can be transported to a laboratory or a storage container for further analysis. Through the automatic control of the electric sliding rail 4 and the driving mechanism 6, the inefficiency of manual sampling is avoided, and the accuracy and consistency of sampling are improved. Through the precise control of the opening and closing assembly 8, it is ensured that the material will not be randomly thrown, and the environmental pollution and material waste are reduced. The device can be applied to different types of conveying belts, has strong adaptability, and does not affect the normal transportation function of the belt.

[0028] In one embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the driving mechanism 6 includes a bearing seat 61. A driving motor 62 is arranged on one side of the upper part of the bearing seat 61. The output end of the driving motor 62 is fixedly connected with a rotating shaft 63. The rotating shaft 63 is rotatably connected in the bearing seat 61. The rotating shaft 63 is fixedly connected with a connecting rod 64. The connecting rod 64 is fixedly connected with the sampling bucket 7. Under the control of the driving motor 62, the sampling bucket 7 can rotate to the position above the conveying belt 2 for sampling. After the sampling bucket 7 collects the material, the driving motor 62 is reversely rotated to make the sampling bucket 7 return to the position above the discharging mechanism 9. By controlling the running time and direction of the driving motor 62, the rotating angle of the sampling bucket 7 can be accurately adjusted to ensure that it accurately extends into the surface of the belt for sampling and can return to the specified discharging position. The bearing seat 61 provides stable support to ensure that the rotating shaft 63 rotates stably, reduces mechanical wear, and improves the service life of the device. The fixed connection of the connecting rod 64 ensures the stability of the sampling bucket 7, so that it does not shake during rotation, and ensures the sampling quality.

[0029] In one embodiment, as shown in Figure 1 , Figure 2 and Figure 4 , a material scooping opening 71 is arranged on the sampling bucket 7. The material scooping opening 71 is arranged on the sampling bucket 7 to ensure that the sampling bucket 7 can more smoothly contact the material scooping opening 71 to ensure that the sampling bucket 7 can uniformly grab the material during sampling, avoiding the problem of uneven samples caused by improper sampling angle or position.

[0030] In one embodiment, as shown in Figure 1 , Figure 3 and Figure 4As shown, the connecting rod 64 is detachably connected with the sampling hopper 7, and when the sampling hopper 7 is worn or damaged, a new sampling hopper 7 can be directly replaced without disassembling the entire driving mechanism 6, thereby improving the maintenance efficiency and reducing the equipment downtime.

[0031] In one embodiment, as shown in Figure 1 、 Figure 3 and Figure 4 , the opening and closing assembly 8 includes a mounting plate 81 fixedly connected to one side of the upper portion of the sampling hopper 7, and the mounting plate 81 is provided with an electric push rod 82, and the telescopic end of the electric push rod 82 is fixedly connected with a sliding bottom plate 83 which is slidingly connected to the bottom of the sampling hopper 7. The mounting plate 81 serves as a fixed support structure to stably mount the entire opening and closing assembly 8 on one side of the upper portion of the sampling hopper 7, ensuring that the electric push rod 82 is not affected by external vibration or impact during operation. The electric push rod 82 serves as a driving execution mechanism and moves the sliding bottom plate 83 when it is extended or retracted, thereby controlling the opening and closing of the bottom of the sampling hopper 7. The sliding bottom plate 83 is slidingly connected to the bottom of the sampling hopper 7 and can serve as a baffle to block the outlet of the sampling hopper 7 in the closed state and release the sampling material in the open state.

[0032] In one embodiment, as shown in Figure 1 、 Figure 2 and Figure 4 , the bottom of the sampling hopper 7 is provided with a chute 72 on both sides, and the sliding bottom plate 83 is slidingly connected between the two chutes 72. The chute 72 serves as a guide rail, and the chutes 72 on both sides of the bottom of the sampling hopper 7 serve as a pair of fixed guide rails to ensure that the sliding bottom plate 83 can slide linearly along the predetermined path without deviation or inclination. The chute 72 reduces the frictional resistance of the sliding bottom plate 83, making it easy to open and close under the drive of the electric push rod 82, improving the motion stability and preventing the sliding bottom plate 83 from being stuck. The design of the chute 72 ensures that the sliding bottom plate 83 always moves horizontally, making the material discharge more accurate and controllable.

[0033] In one embodiment, as shown in Figure 1 、 Figure 2 and Figure 5As shown, the discharging mechanism 9 comprises a discharging frame 91, a discharging hopper 92 is arranged above the discharging frame 91, and a feeding pipe 93 is arranged below the discharging hopper 92. The discharging frame 91 is the basic structure of the entire discharging mechanism 9, used to fix and support the discharging hopper 92 and the feeding pipe 93, to ensure that they remain stable during sampling and conveying and are not affected by vibration or external interference. The structural design of the discharging frame 91 can be adjusted according to different installation environments, so that the discharging hopper 92 is installed at an inclination to optimize the material flow path and improve the discharging efficiency. The discharging hopper 92 and the feeding pipe 93 mainly rely on gravity to convey the material, without the need for additional power devices, thereby reducing energy consumption and improving system reliability. The design of the feeding pipe 93 can ensure that all sampled materials accurately fall into the designated container, avoiding sample waste and improving sampling accuracy. The discharging mechanism 9 can be connected with an automatic analysis device to realize automatic transmission of the sample, thereby improving the automation level of sampling and analysis.

[0034] In one embodiment, referring to Figure 1 and Figure 5 As shown, the feeding pipe 93 is provided with a solenoid valve 931. In the closed state, the solenoid valve 931 can completely cut off the material flow, preventing part of the material from remaining in the feeding pipe 93 and reducing material mixing, thereby ensuring the purity of the sample for each sampling. The solenoid valve 931 is used to control the opening and closing of the feeding pipe 93 and is used for discharging the sampling sample contained in the discharging hopper 92.

[0035] The above is only an example and description of the structure of the present application. Those skilled in the art can make various modifications, supplements or substitutions of similar methods to the described specific embodiments, as long as they do not deviate from the structure of the present application or exceed the scope defined by the present claims, and should belong to the protection scope of the present application.
