The belt conveyor 6 is used for conveying mine dewatered concentrate samples, and the power of belt movement on the belt conveyor 6 can drive the sampling spoon head 5 to run; the sampling spoon head 5 is used for scraping a concentrate sample on a belt of the belt conveyor 6 in the running process, and the sampling knife 9 is used for scraping the concentrate in the sampling spoon head 5 into the receiving hopper 7.

In the embodiment, as shown in fig. 3, the surface of the sampling spoon head 5 is provided with a plurality of grooves 5-1 which are uniformly distributed at intervals and used for scraping a concentrate sample on a belt, each groove 5-1 is equal in size, as shown in fig. 4, the surface of the sampling knife 9 is provided with a protruding tool bit 9-1 matched with the groove 5-1 of the sampling spoon head 5, and the protruding tool bit 9-1 is used for scraping the concentrate in the groove 5-1 into the receiving hopper 7.

In this embodiment, the end of the shaft 3 is fixedly connected to the middle of the coupling body 4 by welding.

In this embodiment, a plurality of sampling spoon heads 5 are uniformly and fixedly connected to the periphery of the outer circular surface of the coupling body 4 at intervals.

In this embodiment, the outer circular surface of the coupling body 4 is fixedly connected with the sampling spoon head 5 by welding.

In this embodiment, the sampling knife 9 is located at the upper end of the center line of the coupling body 4.

In this embodiment, the sampling knife 9 and the sampling hood 8 are fixedly connected by welding.

In this embodiment, the material receiving hopper 7 is a material receiving drawer, a drawer opening (not output in the figure) is formed in the surface of the sampling hood 8, a drawer support is arranged on the inner side of the drawer opening, and the material receiving drawer and the drawer support are connected in a sliding mode through a sliding rail mechanism and can be pulled out from the drawer opening of the sampling hood 8.

The sampler of the embodiment is suitable for sampling various mine dewatering belt concentrates. The sampler solves the problems of unequal time intervals, uneven sampling amount and poor representativeness of sampled samples of manual sampling of the belt concentrate through continuous sampling. The sampling machine samples to satisfy the production requirement of mine concentrate representatively.

The full-automatic dehydrated concentrate sampling machine is a sampling device designed and developed aiming at various dehydrated concentrate sampling, simultaneously, the power required by the full-automatic dehydrated concentrate sampling machine during working completely comes from the belt of the belt conveyor 6 or the power generated during concentrate movement on the belt, no additional energy consumption is needed, and the full-automatic dehydrated concentrate sampling machine is a novel energy-saving and efficient dehydrated concentrate sampling device suitable for various mines.

The present embodiment utilizes the power generated by the movement of the concentrate on the conveyor belt or the belt to drive the sampling spoon head 5 to stick and scrape the concentrate sample and make the sampled sample automatically enter the receiving hopper 7. The working principle of the sampler is very simple, the sampler comprises two bearing seats (bearings are arranged in the bearing seats), a shaft 3, a spoon head connecting body 4 and a sampling spoon head 5, the two bearing seats are used for controlling the shaft 3 on the same line, and when the sampler runs normally, the sampling spoon head 5 cannot swing left and right. The spoon head connecting body 4 is used for connecting the sampling spoon head 5 and the shaft 3 into a whole to realize normal operation. Compress tightly the belt with sample spoon head 5 during the installation, all the other each parts reuse bolt fastening can, when belt conveyor 6 normally operates, because the belt moves forward and produces a forward traction force, sample spoon head 5 just in time compresses tightly the transportation belt and produces a backward frictional force this moment, obtained a counter force opposite with frictional force size phase like this, the impulsive force that has the concentrate of motion to produce simultaneously, thereby promote sample spoon head 5 and move forward, because belt conveyor 6 operates in succession, the power that promotes sample spoon head 5 equally is continuous also, thereby realized the continuous operation of concentrate sampler. When the sampler runs, the sampling spoon head 5 is tightly pressed on the belt, so that the groove 5-1 of the sampling spoon head 5 is also fully adhered with the concentrate, when the sampling spoon head 5 runs to the highest position, a sampling knife 9 is arranged at the position, and the concentrate is scraped from the highest position into the receiving hopper 7 right below by each protruded knife head 9-1 of the sampling knife 9 just opposite to the spoon head groove 5-1, so that unpowered full-automatic sampling is realized. After a certain time, the receiving hopper 7 can be extracted from the sampling hood 8.

The embodiment also carries out sampling effect verification on the dehydrated concentrate sampler. And through manual and mechanical sampling comparison, the grade difference of the concentrate sample is within 0.15%.

The protection scope of the present invention includes but is not limited to the above embodiments, the protection scope of the present invention is subject to the claims, and any replacement, deformation, and improvement that can be easily conceived by those skilled in the art made by the present technology all fall into the protection scope of the present invention.
