Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of efficient cylinder arm integral type cement mixer.
Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Referring to Fig. 1, a kind of efficient cylinder arm integral type cement mixer, including pedestal 1, roller 2, main shaft 3 and auxiliary axis 4, 1 upper end of pedestal is fixedly connected with support frame 5 and mounting rack 6, is fixedly connected with shaft 7 at the 2 left end center of roller, turns Axis 7 is rotatably connected on support frame 5, is rotatably connected to main shaft 3, roller 2 and main shaft by sealing bearing at 2 right end center of roller 3 can individually rotate in the case where being independent of each other, and the main shaft 3 is hollow steel pipe structure, and 3 left end of main shaft is rotatably connected on roller 2 left side walls, 3 right part of main shaft are rotatably connected on mounting rack 6 and stretch out on the right side of mounting rack 6, and main shaft 3 and roller 2 cooperate mutually Stability of strutting system is provided, 3 right end interference of main shaft is connected with driven gear 8, and driven gear 8 and interference are connected to axis and move motor 9 Driving gear 10 in rotation axis engages connection, and the axis moves motor 9 and is fixedly connected on mounting rack 6, moves 9 band of motor by axis Dynamic main shaft 3 rotates, and cylinder is also fixedly connected on mounting rack 6 and moves motor 11, is fixedly connected with biography in the rotation axis of the dynamic motor 11 of cylinder Moving gear 12 corresponds to 12 position of transmission gear on the stack shell of roller 2 and is fixedly connected with ring body gear 13, ring body gear 13 and transmission The engagement connection of gear 12, cylinder, which moves motor 11, can drive roller 2 to rotate;Support plate 14 is fixedly connected on the mounting rack 6, it is described Auxiliary 4 right end of axis is fixedly connected in support plate 14, and auxiliary 4 left end of axis is protruded into main shaft 3 and is rotatably connected on 2 left side wall of roller, is rolled Cylinder 2 does not influence the stability of auxiliary axis 4 when rotating, auxiliary axis 4 is arranged concentrically with main shaft 3, and it is equidistantly equal that auxiliary axis 4 is located at 2 inner part of roller Even is fixedly connected with several driving bevel gears 15, and mixing arm is rotatablely connected on the left of driving bevel gear 15 on the main shaft 3 16, the rotation axis of mixing arm 16 protrudes into main shaft 3 and is fixedly connected with drive bevel gear 17, drive bevel gear 17 and active umbrella tooth 15 engagement connection of wheel, when axis moves motor 9 and main shaft 3 is driven to rotate, mixing arm 16 follows main shaft 3 to revolve, and is driven umbrella at this time Gear 17 is removed along 15 flank of tooth circumferential movement of driving bevel gear so that drive bevel gear 17 drives mixing arm 16 to carry out rotation The additional agitating mode of the conventional outer addition of revolution stirring, makes the stirring of material more thoroughly higher by the rotation of mixing arm 16 Effect, and inputted without additional energy source, operating cost increases unobvious;2 inner wall of roller is also provided with the thread groove being continuously arranged 18, offer discharge port 19 on the left of roller 2, thread groove 18 open up direction should ensure that when roller 2 rotates energy band animal material to It moves left to be discharged from discharge port 19,2 right side opening of roller is equipped with feeding port 20, is slidably connected at discharge port 19 and feeding port 20 There is sealed door, when in use, is kept away by the sealed door that feeding port 20 puts into water and material and closes discharge port 19 and feeding port 20 Exempt to leak, if only forced action type is needed to stir, opens axis and move motor 9, mixing arm 16 carries out revolution at this time and rotation carries out object Material stirring, if only roller is needed to stir, open end can move motor 11, and the only drive of roller 2 material of being failure to actuate of mixing arm 16 is turned over Rolling stirring, can also open simultaneously, the rotation direction of main shaft 3 and roller 2 on the contrary, between mixing arm 16 position material can more with Roller 2 carries out whereabouts completion 2 formula of the roller stirring that raises up, and the material at 16 place position of mixing arm rotates backward drive in roller 2 It is lower to be equal to the covert mixing speed for accelerating mixing arm 16, stirring efficiency is effectively improved, while object is made by thread groove 18 Material is translated in inside, it is ensured that two kinds of agitating modes can act in all materials, and mixing effect is outstanding, need to arrange The sealed door at discharge port 19 is opened when material reduces by 2 revolving speed of roller simultaneously, is existed by the material that thread groove 18 is pushed to 2 left side of roller Discharge port 19 is turned in Shi Huicong roller 2 downward and is fallen, and reduction by 2 revolving speed of roller, which essentially consists in, to be avoided revolving speed too fast and make object Material because whipping phenomenon occurs for centrifugal force, causes to collect difficult and waste when falling, corresponded on pedestal 1 offered at discharge port 19 it is logical Material is open, and completes to collect convenient for placing collection device below pedestal 1, and 1 lower end of pedestal is fixedly connected with stabilizer blade, and stabilizer blade centre is Equipped with spring damper to mitigate operation vibration;Feeding port 20 can 19 direction of discharge port upward when to guarantee to shut down every time Lower section, cylinder, which moves motor 11, should use stepper motor, complete the control of its stroke by step-by-step controller to realize above-mentioned requirements, avoid Feeding discharging control trouble.
