[0018] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a test sample grinding device of the utility model in conjunction with the accompanying drawings.
[0019] like Figure 1-6As shown, the utility model is a test sample grinding device, comprising a support frame 1; a motor 2 is arranged on the support frame 1; a gear box 3 is arranged at the output shaft position of the motor 2; a transmission shaft 4 is arranged on one side of the gear box 3; the gear box 3 drives the transmission shaft 4 to rotate through two oppositely arranged pulleys 5 and a belt 6 connected thereto; a support roller 7 is arranged at one end of the transmission shaft 4 away from the pulley 5; a support rod 8 is rotatably arranged on the upper side of the support frame 1; a support roller 7 is rotatably arranged on one side of the upper end of the support rod 8; a cylinder 9 is arranged between the support rod 8 and the support frame 1; a first connecting frame 10 is slidably arranged on one side of the support frame 1; a grinding frame 11 is rotatably arranged at one end of the first connecting frame 10 away from the support frame 1; The upper and lower ends of the grinding frame 11 are provided with supporting rollers 7 for relative rotation; the multiple supporting rollers 7 are arranged in relative positions; the outer shells of the multiple supporting rollers 7 are provided with grinding belts 12; the support frame 1 is provided with a second connecting frame 13 slidingly arranged on the lower side of the first connecting frame 10; the second connecting frame 13 extends to the outer side of the grinding frame 11 and is provided with a grinding platform 14; the grinding platform 14 is hollow and provided with a negative pressure chamber 1401; the grinding platform 14 is provided with a plurality of suction holes 1402; a material dropping bin 15 is provided on the lower side of the support frame 1; the material dropping bin 15 is connected to the negative pressure chamber 1401 through a corrugated pipe 16; a fan 17 is provided on one side of the material dropping bin 15; the material dropping bin 15 is connected to the air inlet of the fan 17 through a pipe.
[0020] Combination Figure 1-6 As shown, when in use, the motor 2 drives the belt 6, the two pulleys 5 and the transmission shaft 4 through the gear box 3, drives the support roller set at one end of the transmission shaft 4 to rotate, drives the grinding belt 12 set between the multiple support rollers to rotate, the cylinder 9 supports the support rod 8, adjusts the tension of the grinding belt 12 on the multiple support rollers, and rotates the grinding frame 11 set on the first connecting frame 10 to achieve the angle of the grinding belt 12 at the position of the grinding platform 14 by adjusting the angle, and slides and adjusts the first connecting frame 10 and the second connecting frame 13 to adjust the position of the grinding work, places the sample to be polished on the grinding platform 14, starts the motor 2, and rotates the upper and lower ends of the grinding frame 11. A section of grinding belt 12 between the supporting rollers 7 is used to grind the sample, and the grinding efficiency of the sample is high. The obtained powder particles are uniform, which is convenient for subsequent testing. A negative pressure chamber 1401 is arranged in the grinding platform 14, and the fan 17 provides negative pressure for the negative pressure chamber 1401 through the feeding bin 15 and the corrugated pipe 16. When the grinding belt 12 is used to grind the sample at the grinding platform 14, the powder generated by the grinding is sucked into the negative pressure chamber 1401 through the suction hole 1402 and stored in the feeding bin 15, which is convenient for the subsequent collection of sample powder for testing. The powder sample will not be contaminated, and the powder can be prevented from splashing and falling in the air, polluting the environment and being difficult to collect.
[0021] The grinding platform 14 is arranged with an inclined surface opposite to the grinding frame 11. The grinding platform 14 arranged with an inclined surface is opposite to the powder generated by grinding with the grinding belt 12, which makes it easier for the suction hole 1402 arranged thereon to suck the powder into the negative pressure chamber 1401, thereby preventing the powder from splashing to the greatest extent and making it difficult to collect the powder.
[0022] The grinding platform 14 is provided with a suction pipe 18 vertically arranged on both sides of the grinding frame 11; the suction pipe 18 is connected with the negative pressure chamber 1401; the suction pipe 18 is provided with a plurality of suction holes 1402 at a position relative to the grinding frame 11. By cooperating with the suction pipe 18 arranged on both sides of the grinding frame 11 and the suction holes 1402 arranged thereon, it is convenient to suck the powder splashed to both sides generated by grinding with the grinding belt 12 into the negative pressure chamber 1401 through the suction holes 1402, thereby having a better protection effect against powder splashing.
[0023] A baffle 19 is provided at the edge of the polishing platform 14. By placing the sample to be polished on the polishing platform 14 for polishing, the baffle 19 provided at the edge of the polishing platform 14 can effectively prevent the powder generated after polishing from splashing around. The powder is sucked into the negative pressure chamber 1401 in cooperation with the suction hole 1402 provided on the polishing platform 14, thereby maintaining the operating environment and facilitating the collection of the obtained powder.
[0024] A baffle plate 20 is vertically arranged in the drop bin 15; a filter screen 21 is arranged at the connection position between the drop bin 15 and the fan 17. The powder entering the negative pressure chamber 1401 through the suction hole 1402 will reach the drop bin 15 through the corrugated pipe 16. The negative pressure generated by the fan 17 in the drop bin 15 will carry the powder and will be blocked by the baffle plate 20. The powder will then fall into the drop bin 15. A small amount of powder will float up with the negative pressure of the fan 17 and will be blocked by the filter screen 21 to prevent the powder from being blown into the air through the fan 17.
