The lower surface of the bottom plate of the cleaning tank is uniformly and fixedly provided with a plurality of vertical supporting legs along the circumferential direction of the cleaning cavity. When the washing machine works, water is filled into the washing cavity, and then the flaky cloth is fed into the water. The second bevel gear is driven to rotate by the driving motor, and the first bevel gear and the main shaft are driven to rotate by the second bevel gear. The main shaft drives the circular plate and the arc plate to rotate when rotating, and the arc plate drives water in the cleaning cavity to flow when rotating, so that rotating water flow is generated, and the flaky cloth floating on the water surface moves.

Evenly install a plurality of on the circular plate and draw material mechanism, draw material mechanism to include vertical fixed mounting at the guide cylinder of circular plate upper surface, be equipped with the lifter that can vertically reciprocate in the guide cylinder. The lifting rod penetrates through the guide cylinder and the circular plate. The outer side wall of the lifting rod is horizontally and fixedly provided with a support ring, and the upper surface of the circular plate is horizontally provided with a mounting ring which is superposed with the axis of the lifting rod at a position corresponding to the guide cylinder. And a return spring is vertically arranged between the support ring and the mounting ring. The bottom end of the lifting rod is fixedly provided with a magnet column, and the upper surface of the cleaning tank bottom plate is provided with an arc magnet strip which is coincided with the axis of the main shaft at the position corresponding to the magnet column. The bottom plate of the cleaning tank is provided with an air vent. The top end of the lifting rod is horizontally and fixedly provided with an installation disc. The lifting rod and the mounting disc are internally provided with air grooves communicated with each other. The gas tank top port has two and is located the mounting disc upper surface. Two clamping plates are rotatably arranged on the upper surface of the mounting plate, and two air bag columns are fixedly arranged on the upper surface of the mounting plate. The bottom end of the air bag column is communicated with the top port of the air groove, and the top end of the air bag column is fixedly arranged on the clamping plate. The port of gas tank bottom has two and is located the lifter lateral wall.

The opposite surfaces of the two sealing plates are fixedly provided with a first magnet block. The surfaces of the two sealing plates which are opposite to each other are fixedly provided with a second magnet block. And a third magnet block is fixedly arranged on the inner side wall of the guide cylinder corresponding to the second magnet block.

And a sealing block in sliding fit with the ejector rod is arranged in the horizontal groove. And a sealing spring is horizontally and fixedly connected between the sealing block and the end surface of the horizontal groove. When the circular plate rotates, the material pulling mechanism synchronously rotates.

In this case, the air pressure outside the sealing plate is smaller than the air pressure inside the sealing plate. The air under pressure in the air groove enters the air bag column to enable the air bag column to enter an inflated state. The air bag column under the inflation state pushes the clamping plates to rotate, and the two clamping plates approach each other when rotating to clamp the cloth on the water surface. When the magnet column leaves the upper part of the arc-shaped magnet strip, the mutual repulsion force between the magnet column and the arc-shaped magnet strip disappears, the magnet column, the lifting rod, the support ring and the mounting disc move downwards under the action of gravity and the elastic force of the reset spring, and the cloth clamped by the clamping plate moves towards the water surface synchronously. Along with the descending of the lifting rod, the ejector rod penetrates through the magnet column to push the sealing block to enter the horizontal groove, the two first magnet blocks which are adsorbed together are pushed away, the attraction force disappears after the two first magnet blocks are separated, and the air pressure on the outer side of the sealing plate is smaller than the air pressure on the inner side of the sealing plate, so that the sealing plate can slide along the air groove under the action of the air pressure to recover to the initial position. In the process, air in the air bag column returns to the air groove, the two clamping plates do not generate clamping force on the cloth, and the cloth can float on the water surface again.

The lifting rod 82 and the mounting disc 87 are internally provided with air grooves 88 which are communicated with each other. Two air grooves 88 are provided at the top end thereof and are formed on the upper surface of the mounting plate 87. Two clamping plates 89 are rotatably arranged on the upper surface of the mounting disc 87, and two air bag columns 810 are fixedly arranged on the upper surface of the mounting disc 87. The bottom end of the air bag column 810 is communicated with the top port of the air groove 88, and the top end of the air bag column 810 is fixedly arranged on the clamping plate 89. Two ports are arranged at the bottom of the air groove 88 and are positioned on the side wall of the lifting rod 82.

When the magnet post 86 leaves the upper part of the arc-shaped magnet bar 9, the mutual repulsion force between the magnet post 86 and the arc-shaped magnet bar disappears, the magnet post 86, the lifting rod 82, the support ring 83 and the mounting disc 87 rotate to move downwards under the action of gravity and the elastic force of the return spring 85, and the cloth clamped by the clamping plates 89 synchronously rotates below the water surface. With the descending of the lifting rod 82, the top bar 816 passes through the magnet column 86 and pushes the sealing block 818 into the horizontal slot 817, and pushes the two first magnets 812 absorbed together, the two first magnets 812 are separated, the attraction force disappears, and the air pressure outside the sealing plate 811 is smaller than the air pressure inside the sealing plate, so that the sealing plate 811 slides along the air slot 88 under the action of the air pressure and returns to the initial position. In the process, the air in the air bag column 810 returns to the air groove 88, the two clamping plates 89 do not generate clamping force on the cloth, and the cloth can float on the water surface again. A plurality of rubber particles 14 are uniformly and fixedly mounted on the surface of the clamping plate 89, so that the friction force between the clamping plate 89 and the cloth is increased, and the cloth can be clamped tightly by the clamping plate 89.

The surfaces of the two first magnet pieces 812 facing each other are spherical surfaces. The top surface of the lift bar 816 is spherical. The surface of the sealing block 818 which is in sliding fit with the push rod 816 is a spherical surface; thereby ensuring that the top bar 816 can push the first magnet 812 absorbed together and ensuring that the top bar 816 can push the sealing block 818 to move horizontally.

The upper surface of the circular plate 41 is vertically and fixedly provided with a mounting column 15 which is coincident with the axis of the main shaft 3. The top end of the mounting column 15 is fixedly provided with a mounting sleeve 16. A plurality of horizontal mounting shafts 17 are uniformly and rotatably mounted on the outer side wall of the mounting sleeve 16 along the circumferential direction of the mounting column 15. The mounting shaft 17 is disposed radially along the mounting post 15. An agitating plate 18 is fixedly arranged on the mounting shaft 17. The end of the mounting shaft 17 is fixedly provided with a third bevel gear 19. A bevel gear ring 20 which is meshed with the third bevel gear 19 is horizontally and fixedly arranged on the side wall of the cleaning cavity 2. The circular plate 41 rotates to drive the mounting post 15, the mounting sleeve 16, the mounting shaft 17, the stirring plate 18 and the third bevel gear 19 to synchronously rotate horizontally. Because the third bevel gear 19 and the bevel gear ring 20 are in a meshed state, the third bevel gear 19 can drive the mounting shaft 17 and the stirring plate 18 to rotate, and water in the cleaning cavity 2 generates turbulent flow through horizontal rotation and rotation of the stirring plate 18, so that the friction effect of the cloth moving vertically and water flow is further improved, and the washing effect of the water flow on stains on the surface of the cloth is further improved. The stirring plate 17 is a hollow plate to increase the irregular shape of the water flow direction when the stirring plate 17 rotates, so that the water flow can generate friction with the surface of the cloth in all directions.

The concrete admixture preparation device in the embodiment has the following working steps: water is filled into the washing chamber 2 and then the sheet cloth is fed into the water. The second bevel gear 7 is driven to rotate by the driving motor 6, and the first bevel gear 5 and the spindle 3 are driven to rotate by the second bevel gear 7. The main shaft 3 drives the circular plate 41 and the arc plate 42 to rotate when rotating, and the arc plate 42 drives the water in the cleaning cavity 2 to flow when rotating, so that the rotating water flow is generated, and the sheet cloth floating on the water surface moves. Along with circular plate 41 continuously rotates, draw material mechanism 8 periodically with the cloth pull-down on the surface of water, the cloth periodically carries out vertical direction's removal along with rivers horizontal rotation simultaneously, has both improved the friction effect between cloth and the rivers, has also avoided the winding together between cloth and the cloth. After the work is finished, the cloth is fished out of the cleaning cavity 2, and then the water is pumped out.
