The sealing block 4 is adapted to the sealing groove 2. A hydraulic cylinder 6 is rotatably installed outside the top cover 5. One end of the hydraulic cylinder 6 is rotatably installed with a fixed plate 7. The fixed plate 7 is fixedly installed with the stirring tank 1.

[0028] The outer part of the mixing tank 1 is equidistantly and annularly provided with a locking mechanism 8. The top of the mixing tank 1 is equidistantly and annularly provided with second clamping grooves 10, and the top of the top cover 5 is equidistantly and annularly provided with first clamping grooves 9 corresponding to the second clamping grooves 10.

[0029] In this embodiment, when it is necessary to open the top cover 5, first loosen the locking mechanism 8 to release the fixation of the top cover 5 and the mixing tank 1 by the locking mechanism 8. At this time, the hydraulic cylinder 6 contracts to flip and open the top cover 5. When it is necessary to close the top cover 5, the hydraulic cylinder 6 extends to drive the top cover 5 to flip and close. The sealing block 4 is inserted into the inside of the sealing groove 2. Due to the setting of the sealing gasket 3, the sealing performance between the top cover 5 and the mixing tank 1 is improved. Then, the top cover 5 and the mixing tank 1 are fixed by the locking mechanism 8, achieving high sealing performance.

[0030] In one embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, the locking mechanism 8 includes a mounting seat 801. The mounting seat 801 is fixedly installed on the outside of the mixing tank 1 equidistantly and annularly. A screw rod 802 is rotatably installed inside the mounting seat 801. A knob 803 is threadedly connected to the outside of the screw rod 802. When it is necessary to open the top cover 5, loosen the knob 803 to release the fit between the knob 803 and the top cover 5. At this time, rotate the screw rod 802 half a turn to release the fixation of the top cover 5 and the mixing tank 1. When it is necessary to fix the top cover 5 and the mixing tank 1, rotate the screw rod 802. Due to the cooperation of the first clamping groove 9 and the second clamping groove 10, the screw rod 802 respectively penetrates through the top cover 5 and the mixing tank 1, and then lock the knob 803 until the bottom of the knob 803 fits with the top of the top cover 5. The structure is simple and it will not be easy to fall off easily after the screw fixation is removed, improving the practicability.

[0031] In one embodiment, as Figure 1 and Figure 2 shown, a feeding mechanism 11 is provided on the outside of the mixing tank 1, and a crushing mechanism 12 is provided on the top of the feeding mechanism 11. The crushing mechanism 12 can crush the materials, making the mixing of fine materials more uniform. The feeding mechanism 11 can prevent blockage during the process of material entry.

[0032] In one embodiment, as Figure 4As shown in the figure, the feeding mechanism 11 includes a feeding pipe 1101 which is fixedly installed outside the mixing tank 1. An impeller 1102 is rotatably installed inside the feeding pipe 1101. One end of the impeller 1102 penetrates through the feeding pipe 1101 and is connected to a first motor 1103. The first motor 1103 is fixedly installed with the feeding pipe 1101. An air pump 1104 is fixedly installed on one side of the feeding pipe 1101. An air bag 1105 is provided at the output end of the air pump 1104. The air bag 1105 is located inside the feeding pipe 1101. The crushed material falls above the impeller 1102 due to gravity. The rotation of the impeller 1102 is driven by the operation of the first motor 1103. The rotation of the impeller 1102 serves to convey the material and prevent the material from clogging inside the feeding pipe 1101. After the material is added, the air pump 1104 operates to inflate the air bag 1105, thereby blocking the feeding pipe 1101 and serving to seal the mixing tank 1.

[0033] In one embodiment, as Figure 4 shown, the crushing mechanism 12 includes a crushing box 1201 which is fixedly installed on the top of the feeding pipe 1101. Two meshing crushing teeth 1202 are rotatably installed inside the crushing box 1201. One end of each crushing tooth 1202 penetrates through the crushing box 1201 and is provided with a meshing gear 1203. A second motor 1204 is provided at the input end of the gear 1203. The second motor 1204 is fixedly installed with the crushing box 1201. A feeding hopper 1205 is fixedly installed on the top of the crushing box 1201. The material to be mixed is added into the feeding hopper 1205. The material falls between the two crushing teeth 1202 due to gravity. The rotation of the two gears 1203 is driven by the operation of the second motor 1204. The gears 1203 drive the crushing teeth 1202 to rotate, thereby crushing the material. The crushed material is not only convenient for mixing, but also can prevent the feeding pipe 1101 from being clogged, improving the practicability.

[0034] In one embodiment, as Figure 5 shown, a third motor 13 is fixedly installed at the center point of the bottom of the mixing tank 1. A transmission shaft 14 is rotatably installed at the center point inside the mixing tank 1. The transmission shaft 14 is connected to the output end of the third motor 13. Stirring blades 15 are equidistantly arranged outside the transmission shaft 14. Installation grooves 16 are formed outside the stirring blades 15. Scrapers 17 are installed outside the stirring blades 15 through the installation grooves 16. The outer surface of the scraper 17 is fitted with the inner wall of the mixing tank 1. After the material is added, the third motor 13 operates. The third motor 13 drives the transmission shaft 14 to rotate, and the transmission shaft 14 drives the stirring blades 15 to rotate, thereby effectively mixing the material. At the same time, the scraper 17 can scrape off the material adhering to the inner wall of the mixing tank 1, improving the mixing effect.

[0035] In one embodiment, as Figure 1 and Figure 2 shown, a sampling tube 18 and a discharge tube 20 are respectively arranged outside the stirring tank 1. A sampling bottle 19 is threadedly connected to the bottom of the sampling tube 18. Valves are arranged in both the sampling tube 18 and the discharge tube 20. After reaching the stirring time, by opening the valve inside the sampling tube 18, the material enters the inside of the sampling bottle 19 through the sampling tube 18, then the valve is closed, and the sampling bottle 19 is rotated and removed to detect the material inside to determine whether the material meets the mixing standard. If the standard is not met, the stirring continues. If the standard is met, by opening the valve inside the discharge tube 20, the material is discharged through the discharge tube 20.

[0036] In one embodiment, as Figure 1 and Figure 2 shown, legs 21 are equidistantly and annularly installed at the bottom of the stirring tank 1, and the legs 21 effectively support the stirring tank 1.

[0037] The above embodiment discloses a high-sealing mixing device. Among them, the materials to be mixed are added into the inside of the feed hopper 1205. Due to gravity, the materials fall between the two crushing teeth 1202. By the operation of the second motor 1204, the two gears 1203 are driven to rotate, and the gears 1203 drive the crushing teeth 1202 to rotate, thereby crushing the materials. The crushed materials fall above the impeller 1102 due to gravity. By the operation of the first motor 1103, the impeller 1102 is driven to rotate, and the rotation of the impeller 1102 plays a role in conveying materials to prevent the materials from blocking inside the feed pipe 1101. The materials enter the inside of the stirring tank 1. After the materials are added, the air pump 1104 works to make the airbag 1105 expand, thereby blocking the feed pipe 1101 and playing a role in sealing the stirring tank 1. The third motor 13 works, the third motor 13 drives the transmission shaft 14 to rotate, and the transmission shaft 14 drives the stirring blades 15 to rotate, thereby effectively mixing the materials. At the same time, the scraper 17 can scrape off the materials attached to the inner wall of the stirring tank 1, improving the mixing effect. After reaching the stirring time, by opening the valve inside the sampling tube 18, the materials enter the inside of the sampling bottle 19 through the sampling tube 18, then the valve is closed, and the sampling bottle 19 is rotated and removed to detect the materials inside to determine whether the materials meet the mixing standard. If the standard is not met, the stirring continues. If the standard is met, by opening the valve inside the discharge tube 20, the materials are discharged through the discharge tube 20.
