It can replace traditional manual work and improve the efficiency and accuracy of sample preparation. It usually includes automatic sampling, grinding, packaging and other modules, realizing the full process automation from raw coal to laboratory samples. Such a system ensures the representativeness and repeatability of the sample by precisely controlling the operation process, and reduces the impact of human errors. Fully automatic sample preparation equipment is usually highly flexible and can be customized according to different coal types and user needs to meet a variety of test standards.

[0003] According to the search, the Chinese patent document, announcement number: CN209525159U, discloses that the utility model relates to a fully automatic coal sampling system including a fully automatic sampling machine and a sampling machine, wherein the fully automatic sampling machine is provided with three or more, and a two-way transmission device is provided between any two of the fully automatic sampling machines, and the number of the sampling machines matches the number of the two-way transmission devices, and the sampling machines are connected one by one with the two-way transmission devices. In a fully automatic coal sampling system of the utility model, the coal sample is transmitted to the two-way transmission device by the sampling machine, and the coal sample is transmitted to any one of the fully automatic sampling machines at both ends by the two-way transmission device. The utility model has the following advantages: 2 or more sets of fully automatic sampling machines are used as backup for each other, which improves production efficiency and reduces labor intensity.

[0004] In the actual production process, the fully automatic coal sampling system is unable to conduct secondary screening of coal and raw stone, which may affect the overall representativeness of the samples when they are finally shipped out of the factory, resulting in inaccurate subsequent test results and failure to truly reflect the quality of the entire batch of coal. In view of this, I can provide a fully automatic sampling equipment tomorrow. Utility Model Content

[0023] like Figure 1-4 As shown, the utility model provides a technical solution: a fully automatic sample preparation device for coal, comprising a base frame 1, a feed hopper 101 is fixedly connected to the top surface of the base frame 1, and feed baffles 102 are fixedly connected to the two sides of the top surface of the feed hopper 101, a crushing bin 103 is fixedly connected to the outer wall of one side of the base frame 1, and a crushing motor 104 is fixedly connected to the outer wall of one side of the crushing bin 103, a plurality of crushing rollers 105 are rotatably connected to the inner sides of the crushing bin 103 near the top on both sides of the crushing bin 103, and the crushing rollers 105 are rotatably connected to the inner walls of the crushing bin 103 through the crushing motor 104, a plurality of transport rollers 2 are rotatably connected to the two ends of the crushing bin 103, and a transport motor 201 is fixedly connected to one side of the outer wall of the crushing bin 103, and the output end of the transport motor 201 is rotatably connected to the transport roller 2, one end of the crushing bin 103 is fixedly connected to the air guide 202, and one side of the outer side of the air guide 202 is simultaneously fixedly connected to a coal transport plate 203 and a raw stone transport plate 204 through the crushing bin 103.

[0024] Coal ore is put into the top of the feed hopper 101, and the ore will slide along the surface of the feed hopper 101 to the coal mine baffle 109. When the ore falls on the surface of the crushing roller 105, the crushing motor 104 is started, and the crushing roller 105 inside the crushing bin 103 is driven to rotate through the No. 1 belt 107 sleeved on the outer wall of the output end of the crushing motor 104. When the ore is crushed by the crushing roller 105 and falls on one end of the surface of the conveying belt 205, the conveying motor 201 is driven at this time, and the conveying motor 201 drives the conveying belt through the No. 3 belt 3 and the conveying roller 2 at the bottom of the crushing bin 103. 205 rotates to transport the crushed coal to the end away from the crushing roller 105, and drives the screening fan 207 fixed on one side of the wind guide 202 to screen the coal and the raw stone. Since the quality of the coal is much lower than that of the raw stone, the coal will be blown up by the wind blown out from the inside of the wind guide groove 206 and fall on the surface of the coal transport plate 203, while the raw stone will fall on the surface of the raw stone transport plate 204 along the dividing plate 208 due to its larger mass, so that the device can screen the coal and the raw stone while realizing fully automatic sampling of the coal, thereby effectively ensuring the subsequent testing.

[0025] like Figure 1-3As shown, the crushing roller 105 is mainly composed of metal material, and the outer wall of the crushing roller 105 is fixedly connected with a plurality of crushing blocks 106, the outer wall of one end of one of the crushing rollers 105 close to the base frame 1 inside the crushing bin 103 penetrates one side of the inner wall of the crushing bin 103, and the outer wall of the crushing roller 105 near one end and the outer wall of the output end of the crushing motor 104 are sleeved with a No. 1 belt 107, the outer walls of one end of the plurality of crushing rollers 105 rotatably connected inside the crushing bin 103 penetrate one side of the inner wall of the crushing bin 103 and are sleeved with a No. 2 belt 108, and a plurality of corresponding coal mine baffles 109 are fixedly connected to the top of the crushing bin 103, and the coal mine baffle 109 is located at the top center of the crushing roller 105.

[0026] When coal ore is thrown into the top of the feed hopper 101, the ore will slide along the surface of the feed hopper 101 to the coal mine baffle 109. When the ore falls on the surface of the crushing roller 105, the crushing motor 104 is started, and the No. 1 belt 107 connected to the outer wall of the output end of the crushing motor 104 drives the crushing rollers 105 inside the crushing bin 103 to rotate, so that the device can crush the coal by driving the crushing motor 104 to separate the coal from the raw stone, and by placing feed baffles 102 on both sides of the top surface of the feed hopper 101, the ore can be effectively prevented from falling from the surface of the feed hopper 101.

[0027] like Figure 1-4 As shown, the outer wall of one of the transport rollers 2 near the transport motor 201 at the bottom end of the crushing bin 103 passes through one side of the inner wall of the crushing bin 103 and is sleeved with the output end of the transport motor 201 with the third belt 3, the outer wall center of the transport roller 2 is sleeved with a transport belt 205, and the transport belt 205 is located at the bottom end of the crushing bin 103, one end of the outer wall of the transport roller 2 passes through one side of the inner wall of the crushing bin 103 and is sleeved with the fourth belt 4, an air guide groove 206 is opened in the center of the air guide 202, and a plurality of screening fans 207 are fixedly connected to the outer wall of one side of the air guide 202, a cotton net is fixedly connected to the top of the air guide groove 206, the top surfaces of the coal transport plate 203 and the raw stone transport plate 204 are provided with arc grooves, and the outer walls of the coal transport plate 203 and the raw stone transport plate 204 are fixedly connected with dividing plates 208 on both sides.

[0028] When the ore is crushed by the crushing roller 105 and falls on one end of the surface of the conveyor belt 205, the conveyor motor 201 is driven at this time. The conveyor motor 201 drives the conveyor belt 205 to rotate through the No. 3 belt 3 and the conveyor roller 2 at the bottom end of the crushing bin 103, so that the crushed coal is transported to the end away from the crushing roller 105, and the screening fan 207 fixed on one side of the air guide 202 is driven to screen the coal and the raw stone. Since the quality of the coal is much lower than that of the raw stone, the coal will be blown up by the wind blown out from the inside of the air guide groove 206 and fall on the surface of the coal conveyor plate 203, while the raw stone will fall on the surface of the raw stone conveyor plate 204 along the dividing plate 208 due to its larger mass, so that the device can screen the coal and the raw stone while realizing fully automatic sampling of the coal, thereby effectively ensuring the subsequent testing.

[0029] Working principle: Coal ore is put into the top of the feed hopper 101, and the ore will slide along the surface of the feed hopper 101 to the coal mine baffle 109.

When the ore is crushed by the crushing roller 105 and falls on one end of the surface of the conveying belt 205, the conveying motor 201 is driven at this time. The conveying motor 201 is driven by the No. 3 belt 3 and the conveying belt 205 at the bottom of the crushing bin 103. The conveyor roller 2 drives the conveyor belt 205 to rotate, so that the crushed coal is transported to the end away from the crushing roller 105, and drives the screening fan 207 fixed on one side of the wind guide 202 to screen the coal and the raw stone. Since the quality of the coal is much lower than that of the raw stone, the coal will be blown up by the wind blown out from the inside of the wind guide groove 206 and fall on the surface of the coal conveyor plate 203, while the raw stone will fall on the surface of the raw stone conveyor plate 204 along the dividing plate 208 due to its larger mass, so that the device can screen the coal and the raw stone while realizing fully automatic sampling of the coal.
