[0021] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] In order to achieve the above purpose, the embodiment of the present utility model adopts the following technical solutions: Figure 1 、 Figure 2 , an automatic sampling device for raw and fuel materials, including a bracket 10 arranged on a belt frame, a sampling mechanism and a trigger mechanism. Further, the sampling mechanism is arranged at the unloading port of the belt head entering the auxiliary material yard, and the sampling mechanism can be freely extended to realize the function of automatic sampling. Specifically, the sampling mechanism includes a power unit, a sampling unit arranged at the output end of the power unit, and a discharge unit arranged at the bottom of the sampling unit and capable of automatically opening and closing. The existence of the discharge unit is to realize the automatic falling of the material into the silo after sampling. The trigger mechanism can be triggered by the material on the belt to drive The sampling mechanism is activated to perform sampling. When the material on the belt 40 contacts the trigger mechanism, a signal is sent to the sampling mechanism, causing the power unit in the sampling mechanism to operate, driving the sampling unit to extend and sample. After sampling is completed, the sampling unit returns to its original position and retracts. When the discharge unit opens, the sampled material is discharged into the silo. By combining automatic electrical control with mechanical equipment, this utility model can automatically complete sampling when raw materials enter the yard, effectively avoiding errors caused by human factors and ensuring that the quality assessment of each batch of raw materials is based on the most authentic and representative sample data. This improves the efficiency and accuracy of the acceptance of raw and fuel materials entering the factory.

[0023] Furthermore, the power part is a driving cylinder 220, so that when sampling, the sampling part is driven to extend through the piston rod at the output end of the driving cylinder to perform the sampling operation.

[0024] Furthermore, the sampling part is a sampling shovel 230, which is arranged at the output end of the driving cylinder 220, so that when the driving cylinder moves, the sampling shovel can be driven to extend and retract synchronously to achieve sampling and resetting after sampling. Specifically, the sampling shovel includes a shovel top plate 231, a shovel side plate 232 and a shovel end plate 233. There are two shovel side plates 232, and the two shovel side plates are relatively arranged on both sides of the shovel top plate. At the same time, the shovel end plate 233 is arranged at one end position of the shovel top plate. It should be noted that the shovel end plate is connected to the output end of the driving cylinder 220. When in use, the shovel top plate 231, the shovel side plate 232 and the shovel end plate 233 form the main structure of the shovel body. Under the drive of the driving cylinder, the material can be sampled through the shovel body.

[0025] Furthermore, the unloading part is specifically a shovel bottom plate 210, which is arranged below the shovel top plate 231, and the shovel bottom plate, shovel top plate 231, shovel side plate 232 and shovel end plate 233 form a box structure with one end open. It should be noted that the shovel bottom plate 210 in this embodiment is rotatably set on the shovel end plate 233, and can be abutted against the shovel side plate to form a parallel distribution with the shovel top plate when rotated upward, that is, a box structure with one end open is formed to facilitate sampling operations; and when the shovel bottom plate 210 is rotated downward, the bottom of the box structure is opened to facilitate unloading of materials into the silo after the sampling is completed.

[0026] Further, refer to Figure 3 The trigger mechanism includes a trigger sensor 310 and a contact plate 320. The trigger sensor 310 is arranged on the bracket 10, and the contact plate 320 is suspended above the belt. The contact plate 320 is electrically connected to the trigger sensor. It should be noted that the weight of the contact plate 320 must be sufficient to automatically flip over after it contacts the material flow, so that the trigger sensor 310 automatically senses. When in use, under the action of the material flow, the contact plate is forced to flip over. At this time, the trigger sensor is triggered and sends a signal to the driving cylinder to realize the linkage sampling shovel to obtain an automatic sampling effect.

[0027] During use, the material is conveyed along the belt, and the contact plate 320 in the trigger mechanism is suspended above the belt. When the material flow contacts the contact plate 320, the contact plate 320 will be driven to flip. At this time, the trigger sensor 310 senses the signal and sends a signal to the drive cylinder 220 to realize the action of the drive cylinder 220. The drive cylinder 220 then drives the sampling shovel to extend for sampling. After the sampling is completed, the sampling shovel retracts under the action of the drive cylinder 220, and when the shovel bottom plate 210 is rotated open, the sampled material is unloaded into the silo. The utility model combines automatic control of electrical equipment and mechanical equipment to automatically complete the sampling work when the raw materials enter the yard, effectively avoids errors caused by human factors, and ensures that the quality assessment of each batch of raw materials is based on the most real and representative sample data.

In the figure, incoming raw materials are conveyed to the rear of the discharge port belt 40. A trigger mechanism is provided on the discharge port belt 40. When a trigger sensor in the trigger mechanism senses material flow on the belt, it automatically triggers the sampling mechanism to start sampling. The sampling mechanism operates at a preset sampling frequency, and after a certain period of time, the sampling personnel can remove the sample from the silo 50. In addition, to facilitate maintenance of the automatic sampling device, a maintenance platform 60 is provided next to the automatic sampling device. A staircase 70 is provided on the side of the maintenance platform 60. Access to the maintenance platform allows maintenance of the automatic sampling device via the staircase.
