[0031] The scheme in Embodiment 1 is further introduced below in combination with a specific working mode, and details are described below:

[0032] As Figure 1 , Figure 6 , Figure 7As shown, in some embodiments, the first crushing mechanism 5 includes a round rod 501 rotatably connected inside the first crushing box 3, a plurality of rotor hammers 502 are fixedly installed on the outer surface of one end of the round rod 501 inside the first crushing box 3, one end of the round rod 501 penetrates through the first crushing box 3 and is fixedly installed with a first driving bevel gear 503, the outer surface of the first driving bevel gear 503 is engaged with a first driven bevel gear 504, one end of the first driven bevel gear 504 away from the first driving bevel gear 503 is drivingly connected with a belt 505, the second crushing mechanism 8 includes a rotating shaft 801 symmetrically rotatably connected inside the second crushing box 7 and a mounting box 802 fixedly installed on the side of the second crushing box 7, a grinding roller 803 is fixedly connected to the middle part of the rotating shaft 801, a driving mechanism 13 is arranged inside the mounting box 802 and is used to drive the two rotating shafts 801 to rotate simultaneously, one of the rotating shafts 801 is rotatably connected with a U-shaped plate 14 between the two ends of the rotating shaft 801 outside the second crushing box 7, the two side walls of the second crushing box 7 are constructed with a rectangular channel 15 for the sliding of the rotating shaft 801, the middle part of the U-shaped plate 14 is rotatably connected with a screw rod 16, one end of the screw rod 16 away from the U-shaped plate 14 is fixedly connected with a rotating handle 17 through the thread connection with the side wall of the mounting box 802, the driving mechanism 13 includes a double-shaft motor 1301 fixedly installed on the side wall of the mounting box 802 and a connecting plate 18 fixedly installed on one side of the U-shaped plate 14, one output shaft of the double-shaft motor 1301 is fixedly connected with a shaft rod 1302, the other output shaft of the double-shaft motor 1301 is drivingly connected with the belt 505, both ends of the shaft rod 1302 are rotatably connected with the inner side wall of the mounting box 802, one end of the shaft rod 1302 close to the double-shaft motor 1301 is fixedly connected with a second driving bevel gear 1303, one end of the rotating shaft 801 close to the double-shaft motor 1301 is fixedly connected with a second driven bevel gear 1304, the second driving bevel gear 1303 and the second driven bevel gear 1304 are engaged with each other, a sleeve 19 is rotatably connected inside the connecting plate 18, one end of the sleeve 19 away from the connecting plate 18 is fixedly connected with a third driving bevel gear 1305, one end of the other rotating shaft 801 is fixedly connected with a third driven bevel gear 1306, the third driving bevel gear 1305 and the third driven bevel gear 1306 are engaged with each other, one end of the shaft rod 1302 away from the double-shaft motor 1301 is fixedly connected with a clamping plate 20, a groove matched with the clamping plate 20 is arranged inside the sleeve 19 and the third driving bevel gear 1305, the working principle here is that when the coal and other materials enter the first crushing box 3, the double-shaft motor 1301 can be turned on, the other output shaft of the double-shaft motor 1301 drives the belt 505 to drive the first driven bevel gear 504 to rotate, the outer surface of the first driving bevel gear 503 is engaged with the first driven bevel gear 504, therefore the first driving bevel gear 503 will rotate following the rotation of the first driven bevel gear 504, so that the round rod 501 rotates, a plurality of rotor hammers 502 are fixedly installed on the round rod 501, with the rotation of the round rod 501,The rotor hammer 502 will crush the material entering the first crushing box 3, and the material will gradually become smaller under the impact and extrusion of the rotor hammer 502, and then enter the second crushing mechanism 8 through the outlet of the first crushing box 3. The second crushing mechanism 8 includes a rotating shaft 801 symmetrically connected inside the second crushing box 7, a grinding roller 803 fixed on the rotating shaft 801, and a double-shaft motor 1301 as the core component of the driving mechanism 13 arranged inside the mounting box 802. One output shaft directly drives the shaft rod 1302 to rotate, and the shaft rod 1302 is fixed with a second driving bevel gear 1303. The second driving bevel gear 1303 is meshed with a second driven bevel gear 1304 at one end of the rotating shaft 801 close to the double-shaft motor 1301. Therefore, when the shaft rod 1302 rotates, it will drive the rotating shaft 801 to rotate. At the same time, the sleeve 19 inside the connecting plate 18 is rotatably connected with a third driving bevel gear 1305, and the other end of the sleeve 19 is meshed with a third driven bevel gear 1306 at one end of the other rotating shaft 801.

The sleeve 19 and the third driving bevel gear 1305 are provided with a groove matched with the clamping plate 20. This design allows the relative position of the clamping plate 20 and the groove to be adjusted to lock or unlock the rotation of the sleeve 19 when needed, thereby controlling the transmission relationship between the third driving bevel gear 1305 and the shaft rod 1302. However, under normal working conditions, the clamping plate 20 and the groove do not directly participate in transmission, but exist as a standby or adjustment mechanism. With the synchronous rotation of the two rotating shafts 801, the grinding rollers 803 fixed on the rotating shafts 801 also begin to rotate. The symmetrical arrangement and synchronous rotation of the grinding rollers 803 ensure the uniformity and efficiency of the material during the crushing process. The U-shaped plate 14 is threadedly connected to the side wall of the mounting box 802 through the screw rod 16 and is fixed between the outer two ends of one rotating shaft 801. The handle 17 is used to rotate the screw rod 16, thereby adjusting the relative position between the U-shaped plate 14 and the mounting box 802.

[0033] Step 1: When the combined sample preparation machine is needed, when the servo motor 202 starts to rotate, since one of the transport rollers 203 penetrates the side of the transport shell 201 and is fixedly connected with the output shaft of the servo motor 202, the transport roller 203 will rotate with the rotation of the servo motor 202. Through the transmission of the conveyor belt 204, the other transport rollers 203 also begin to rotate synchronously, forming a continuous circular motion. Coal and other materials are guided onto the conveyor belt 204 through the feed hopper 205, and with the continuous motion of the conveyor belt 204, the materials enter the first crushing box 3 through the feed inlet arranged at the top of the first crushing box 3 for crushing treatment

[0034] Work step two: at this time, because the first baffle 4 is not opened, so that the coal and other materials accumulated in the first crushing box 3, start the double shaft motor 1301, that is, the other output shaft of the double shaft motor 1301 rotates, so that the belt 505 rotates, driving the first driven bevel gear 504 to rotate, the first driving bevel gear 503 is engaged with the outer surface of the first driven bevel gear 504, so that the first driving bevel gear 503 will follow the rotation of the first driven bevel gear 504 to rotate, so that the round bar 501 rotates, the round bar 501 is fixedly installed with a plurality of rotor hammers 502, with the rotation of the round bar 501, the rotor hammers 502 will preliminarily crush the materials entering the first crushing box 3, pull the first baffle 4, so that the first baffle 4 slides out of the side of the first crushing box 3, the bottom of the first crushing box 3 is connected to the second crushing box 7 and the belt conveyor body 9 through the diverging hopper 6, the belt conveyor body 9 is located directly below the other discharge port of the diverging hopper 6, for directly conveying the part of the materials to the open place by the coal pusher to push away the sample, through the diverging hopper 6 one discharge port into the second crushing box 7, one of the output shafts of the double shaft motor 1301 directly drives the shaft rod 1302 to rotate, the shaft rod 1302 is fixedly provided with the second driving bevel gear 1303, the second driving bevel gear 1303 is engaged with the second driven bevel gear 1304 close to one end of the shaft 801 of the double shaft motor 1301, so that when the shaft rod 1302 rotates, it will drive the shaft 801 to rotate, at the same time, the sleeve 19 inside the connecting plate 18 is rotatably connected with the third driving bevel gear 1305, the other end of the sleeve 19 is engaged with the third driven bevel gear 1306 at one end of the other shaft 801, so that the two shafts 801 realize synchronous rotation, further crushing and grinding the materials entering the second crushing mechanism 8, when it is needed to collect specific materials, the second baffle 10 can be opened, the collecting hopper 11 is fixed inside the second crushing box 7, located directly below the second baffle 10, for receiving the materials processed through the second crushing box 7 and meeting the specific conditions, the two collecting boxes 12 below the collecting hopper 11 can slide on the side of the second crushing box 7, facilitating taking out the collected materials. It should be noted that the first baffle 4 and the second baffle 10 can be fixedly connected by screws; the diverging hopper 6 is provided with two discharge ports, one discharge port is fixedly communicated with the top of the second crushing box 7 and the other discharge port is arranged directly above the belt conveyor body 9, when the first baffle 4 is pulled out of the side of the first crushing box 3, the coal in the first crushing box 3 will come to the second crushing box 7 and the other half comes to the belt conveyor body 9 from the other discharge port.

[0035] Step three: when the large coal needs to be ground, the screw rod 16 drives the U-shaped plate 14 to move to the outside of the second crushing box 7 by rotating the handle, so that the distance between the two grinding rollers 803 is increased, when the small coal needs to be ground, the distance between the two grinding rollers 803 is reduced by rotating the handle. The position of the rectangular channel 15 is provided with a scale value, which is beneficial to control the degree of coal grinding, the larger the value, the more sufficient the grinding. It should be noted that: Figure 5 The numbers 1, 2 and 3 represent the level, that is, the distance between the two grinding rollers 803.
