Through set up water spray plate 42 in wasing 4 inside tops of case, can spout water downwards, not only can carry out the dust fall in wasing case 4, still can wash the cement bag of below, wash down its remaining cement in the surface and arrange agitator tank 1, the waste of cement has been reduced, and when taking out moist cement bag in the later stage, also do not have cement ash to fill, comparatively practice thrift the environmental protection, and set up annular spray pipe 5 in agitator tank 1 inner chamber bottom, adopt the mode that sprays to replace direct water injection, also can realize the dust fall when watered, reduce the cement that up floats.

Please refer to fig. 9, the center of steel ball bearing fretwork supporting disk 233 is passed through at the top of screw seat 2342, the bottom of drive shaft 234 runs through to the inside of agitator tank 1, the surface of urceolus 2341 just is located the top fixedly connected with ash blocking seat 2345 of agitator tank 1, ash blocking seat 2345 can avoid the cement that falls to fall to on the synchronizing wheel, the top of agitator tank 1 just is located the outside of ash blocking seat 2345 and has seted up into the ash hole, advance seting up of ash hole and need avoid the top of hold-in range, fixedly connected with H type support 3 between the front and back both sides of agitator tank 1 inner wall, the bottom of urceolus 2341 is passed through the bearing and is connected with the left side rotation at H type support 3 top, and the left side fixed connection at the bottom of guide bar 2344 and H type support 3 top.

The center fixedly connected with motor 10 at 1 top of agitator tank, motor 10 is servo motor, it is fixed that the number of turns is just reversing, restriction screw thread section of thick bamboo 2343's lift height, the bottom of motor 10 output shaft runs through to 1 inside and fixedly connected with agitator tank 11 of agitator tank, 11 bottom centers of agitator tank set up to the auger form, and extend to inside the discharge gate, can avoid blockking up when the ejection of compact, be connected through the transmission of hold-in range subassembly 12 between the surface of motor 10 output shaft and urceolus 2341 bottom, and the mid portion of H type support 3 shelters from the below at hold-in range subassembly 12, the cement that splashes when H type support 3 can avoid the stirring is infected with hold-in range subassembly 12 surface, cause the card to pause after later stage is dry.

Meanwhile, the contents which are not described in detail in the specification belong to the prior art which is known by the person skilled in the art, and the model parameters of each electric appliance are not particularly limited, and conventional equipment can be used.

When the cement bag grinding device is used, a whole bag of cement is put into the dust-free feeding mechanism 2 from the top, the cement sequentially props up the sealing turning plate 25 and the discharging frame 24 to fall onto the hollow supporting plate 233, then the sealing turning plate 25 and the discharging frame 24 rebound and reset under the resilience of the rubber band 26 and the torsion spring, the motor 10 is started, the outer barrel 2341 is driven to rotate through the synchronous belt assembly 12, the ring-shaped cutter 231 is further driven to rotate, the top cutting edge of the ring-shaped cutter 231 cuts the bottom of the cement bag to fall the cement, meanwhile, the outer barrel 2341 is driven to slowly rise through the thread to jack the center of the cement bag upwards, the cement is thoroughly discharged, the falling cement firstly passes through the metal mesh 2310, at the moment, large cement blocks are gradually scattered from the bottom by the steel wire 2312 in the ring-shaped cutter 231 and then pass through the bottom of the ring-shaped cutter 231 to fall onto the grinding chassis 236, when the ring-shaped cutter 231 rotates, the protrusions 2314 at the bottom of the ring-shaped cutter, the protrusions 237 and the grinding chassis top 236 and the grinding stop rod 237 generate grinding force, the caked cement is fully ground, the ring-shaped cutter 231 synchronously drives the semicircular sliding block 2315 at the bottom to rotate when rotating, when the semicircular sliding block 2315 rotates to the horizontal surface of the top edge of the grinding chassis 236, the semicircular sliding block 2315 is pressed downwards, when the semicircular sliding block 2315 rotates to the inside of the waveform groove 2361 of the top edge of the grinding chassis 236, the grinding chassis 236 moves upwards under the elastic force of the spring 239, the grinding chassis 236 is further caused to intermittently move upwards and downwards, the grinding chassis 236 and the grinding stop rod 237 can form a relatively closed partition when ascending, the cement retention time is prolonged, and the ground cement can pass through the material leakage hole 238 and fall to the lower part when sliding downwards until falling into the stirring box 1; the graphite alkene of granule can be artifical cut the bag and throw in dustless feed mechanism 2, need not to carry out machinery and cuts the bag and grind, if the graphite alkene powder that uses, can adopt and throw in with the same mode of cement.

After a bag of cement is put in, along with the continuation of screw thread section of thick bamboo 2343 rises, can push up the cement bag wholly, until the upper strata of propelling movement to the partial bottom of play work or material rest 24, then motor 10 reversal control screw thread section of thick bamboo 2343 descends and resets, and the cement bag is taken on play work or material rest 24 and is slided to the washing case 4 left in.

The water pump 6 is started to pump water source through the water suction pipe 7, the water source is discharged into the annular water spray pipe 5 through the water discharge pipe 8, the water is sprayed downwards for dust fall and water addition, meanwhile, part of water is discharged to the upper layer of the sealing door 41 through the branch pipe 9, water is sprayed downwards through the water spray holes in the bottom of the sealing door 41, the dust fall is carried out in the cleaning box 4, the cement bag is washed, the cement remained on the surface of the cement bag is washed down and discharged into the stirring box 1, a period of time is waited after the feeding is finished, and after the dust is completely settled, the sealing door 41 can be opened to take out the cement bag.

Motor 10 can drive stirring frame 11 when rotating and rotate together, carries out abundant mixing stirring to graphite alkene, cement and water, can open the valve discharge material of agitator tank 1 bottom after the stirring.
