The driving shaft 402 is connected with the first screw rod 23 in a transmission manner, so that the first screw rod 23 can be driven to rotate, cement and sand entering the first discharge pipe 21 are mixed in advance, in the rotating process, through the sieve holes 24 uniformly formed in the screw blade portion of the first screw rod 23, the diameter of the sieve holes 24 is larger than the design of the maximum diameter required by the standard of sand particles, cement and sand with qualified sizes can fall downwards through the sieve holes 24 on the first screw rod 23, further enter the stirring tank 1 through the first discharge pipe 21, are made into concrete after being stirred by adding water, and finally are discharged and loaded through the discharging pipe 7 for use, and sand, impurities and cement agglomerates with large particles cannot be conveyed upwards through the sieve holes 24 on the first screw rod 23 along with the rotation of the first screw rod 23, fall outwards into the collecting tank 22 at the top end of the first discharge pipe 21, and are finally discharged and treated through the discharging pipe 25.
When concrete with different proportions needs to be prepared, the knob 413 is unscrewed to push the threaded rod 412 to move up and down, the knob 413 can be screwed again at any position to fix the threaded rod 412, and in the process of moving the threaded rod 412 up and down, the threaded rod 412 is fixedly connected with the cylinder 410 at the periphery of the driving shaft 402, so that the cylinder 410 can be driven to move up and down.
When the cylinder 410 at the periphery of the driving shaft 402 is pushed to move upwards, the cylinder 410 at the left side and the right side can be driven to synchronously move upwards by the action of the connecting rods 411 at the left side and the right side, the upward movement of the cylinder 410 at the periphery of the driving shaft 402 can push the upper movable driving wheel 406 to move upwards against the tension of the spring 409 so as to reduce the distance between the upper movable driving wheel 406 and the fixed driving wheel 405, and simultaneously the upward movement of the cylinder 410 at the periphery of the driving shaft two 404 can enable the upper movable driving wheel 406 to move upwards under the tension of the spring 409 so as to increase the distance between the movable driving wheel 406 and the fixed driving wheel 405 on the driving shaft two 404, and further the steel belt 407 between the driving shaft 402 and the driving shaft two 404 is expanded outwards at the driving shaft 402 and contracted inwards at the driving shaft two 404 so as to increase the transmission ratio of the driving shaft two 404 so as to increase the rotation speed of the driving shaft two 404; simultaneously, the upper movement of the cylinder 410 at the periphery of the driving shaft 402 also enables the lower movable driving wheel 406 to move upwards under the action of the tension force of the spring 409 to increase the interval between the lower movable driving wheel 406 and the fixed driving wheel 405, and simultaneously, the upper movement of the cylinder 410 at the periphery of the driving shaft one 403 pushes the lower movable driving wheel 406 to move upwards against the tension force of the spring 409 to reduce the interval between the movable driving wheel 406 and the fixed driving wheel 405 on the driving shaft one 403, so that the steel belt 407 between the driving shaft 402 and the driving shaft one 403 is contracted inwards at the driving shaft 402, and is expanded outwards at the driving shaft one 403, thereby reducing the transmission ratio of the driving shaft one 403 and reducing the rotating speed of the driving shaft one 403.
And in the same way, when the cylindrical drum 410 moves downwards by using the threaded rod 412, the rotation speed of the first transmission shaft 403 can be increased, the rotation speed of the second transmission shaft 404 is reduced, the first transmission shaft 403 and the second transmission shaft 404 are connected with the second screw rods 34 inside the two storage tanks 31 on the left and right sides by using the transmission connection of the first transmission shaft 403 and the second transmission shaft 404, the rotation speeds of the second screw rods 34 inside the two storage tanks 31 on the left and right sides can be changed by regulating and controlling the rotation speeds of the first transmission shaft 403 and the second transmission shaft 404, and when the rotation speed of the second screw rods 34 is increased, the discharging is accelerated, otherwise, the discharging is slowed down, and further, the regulation and control on the adding proportion of cement and sand in the two storage tanks 31 on the left and right sides can be realized, in addition, only the distance of the up-down displacement of the threaded rod 412 is required to be regulated in operation, the operation is convenient, the operation can be switched at any time, and the normal operation of feeding and stirring is not affected.
