[0040] A first scraping rod 20 is vertically arranged between the two support rods 18 in one group, and the first scraping rod 20 is fixedly connected with the two support rods 18. At the same time, the first scraping rod 20 is in sliding contact with the inner wall of the tank body 3. The first scraping rod 20 is used for scraping the mineral material adhered to the inner wall of the tank body 3.

[0041] The bottom end of the inner tube 10 is coaxially fixedly connected with a connecting rod 24, a fixed sleeve 25 is fixedly arranged on the connecting rod 24, a second scraping rod 26 is fixedly installed on the fixed sleeve 25, and the second scraping rod 26 is in sliding contact with the inner wall of the discharge pipe 27 to scrape the mineral material adhered to the inner wall of the discharge pipe 27.

[0042] The working principle of the first embodiment is as follows: during stirring, the first water outlet holes 16 are closed by the outer tube 15, the second water outlet holes 17 are closed by the inner tube 10, and each first water outlet hole 16 is completely staggered with the corresponding second water outlet hole 17.

[0043] At this time, the motor 5 is started, and the output shaft of the motor 5 drives the first gear 13 and the reciprocating screw rod 7 to rotate.

[0044] When the first gear 13 rotates, it pushes the second gear 14 to rotate. The second gear 14 drives the outer tube 15 to rotate, and the outer tube 15 drives all the support rods 18 to rotate. The four support rods 18 drive the two rotating shafts 21 to revolve around the outer tube 15. In this process, since the two third gears 23 are in mesh with the tooth ring 19, the two third gears 23 rotate around the rotating shafts 21 revolving around the outer tube 15. Thus, the two third gears 23 drive the two rotating shafts 21 to rotate, and the two rotating shafts 21 drive the stirring blades 22 to stir the mineral materials in the tank body 3.

[0045] At the same time, the two support rods 18 drive the first scraper 20 to scrape the mineral materials adhered to the inner wall of the tank body 3.

[0046] In the process of rotating the reciprocating screw rod 7, the inner ring of the one-way bearing is driven to rotate by friction, and at this time, the outer ring of the one-way bearing is in a stationary state.

[0047] In the process of rotating the outer tube 15, the inner tube 10 is pushed to rotate synchronously by the sliding groove and the sliding block. In this process, the inner tube 10 rotates relative to the water injection pipe 12. At the same time, the inner tube 10 drives the connecting rod 24 to rotate synchronously, and the connecting rod 24 drives the second scraper 26 to scrape the mineral materials on the inner wall of the discharge pipe 27. According to the prior art, the discharge pipe 27 is provided with a valve, which is not described in this embodiment.

[0048] When flushing, the output shaft of the motor 5 reverses, and drives the reciprocating screw rod 7 to reverse. At this time, the inner ring and the outer ring of the one-way bearing move synchronously, and the reciprocating screw rod 7 pushes the one-way bearing to move upwards. The one-way bearing drives the push plate 8 to move upwards, and the push plate 8 pushes the transmission ring 9 to move upwards. The transmission ring 9 drives the inner tube 10 to slide upwards while rotating with the inner tube 10. The inner tube 10 and the water injection pipe 12 slide and rotate relative to each other.

[0049] When all the first water outlets 16 are completely communicated with the corresponding second water outlets 17, the motor 5 is turned off, and water is injected into the inner tube 10 through the water injection pipe 12. The water in the inner tube 10 is sprayed into the tank body 3 through the first water outlets 16 and the second water outlets 17, so as to flush the inside of the tank body 3.

[0050] At this time, the motor 5 can be started again, and the output shaft of the motor 5 drives the reciprocating screw rod 7 to rotate, and the reciprocating screw rod 7 drives the inner ring of the one-way bearing to rotate again. In this process, the outer tube 15 drives the inner tube 10 to rotate synchronously, so as to make the flushing of the inside of the tank body 3 more thorough.

[0051] When it is needed to restore to the state that the first water outlet hole 16 is closed by the outer tube 15, the second water outlet hole 17 is closed by the inner tube 10, and each first water outlet hole 16 is completely staggered with the corresponding second water outlet hole 17 up and down, the motor 5 can be started again, and the output shaft of the motor 5 drives the reciprocating screw rod 7 to rotate.

[0052] Embodiment two: the utility model provides a preparation system of asphalt concrete as shown in the figure, and the difference between this embodiment and embodiment one is that the driving part comprises an electric push rod 28, the electric push rod 28 is fixedly installed on the horizontal plate of the support plate 2, and meanwhile the telescopic shaft of the electric push rod 28 is fixedly connected with the push plate 8. Figure 6

[0053] The working principle of embodiment two: the difference between the working principle of this embodiment and embodiment one is that the principle of moving the push plate 8 up and down is different.The telescopic shaft of the electric push rod 28 is telescopic, and the push plate 8 is moved up and down.

[0054] The other working processes of this embodiment are the same as those of embodiment one, and will not be described in detail here.

[0055] Finally, it should be pointed out that: the above-mentioned is only the preferred embodiment of the utility model, and is not used for limiting the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing embodiments, or equivalent replacement is carried out to part of technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model, should be contained in the protection scope of the utility model.​
