Specific embodiment

To make the objectives, technical solutions and advantages of the present invention clearer, With reference to embodiment And referring to attached drawing, the utility model is further described.It should be understood that these descriptions are merely illustrative, and do not really want Limit the scope of the utility model.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to avoid not Necessarily obscure the concept of the utility model.

Specific embodiment 1: in conjunction with shown in Fig. 1-4, a kind of concrete processing speed reducer is it is characterized by: a kind of coagulation Soil processing speed reducer, it is characterised in that: including speed reducer 1, fixed frame 2, compound gearing 3；It is provided on the right side of speed reducer 1 defeated Enter axis 101；Output shaft 102 is provided on the left of speed reducer 1；It is fixedly welded on the right side of 3 left side of compound gearing and speed reducer 1；It is multiple 3 right side of transmission device is closed to be fixedly connected with fixed frame 2；The uniform screw in 3 periphery of compound gearing is fixedly installed with multiple motors 4；Compound gearing 3 includes fixed lock tube 301, the first deep groove ball bearing 302, the second deep groove ball bearing 303 and tension spring 304； Fixed 301 left side of lock tube and speed reducer 1 weld；Fixed 301 right side of lock tube is fixedly connected with fixed frame 2；Fixed 301 middle part of lock tube It is provided with gearcase 305；Drive bevel gear 306 is installed in the middle part of gearcase 305；Drive bevel gear 306 and 101 key of input shaft connect It connects；Fixed 301 periphery of lock tube is evenly arranged with multiple attachment bases 307；307 inner bottom of attachment base, which runs through, is equipped with transmission shaft 308；308 bottom key of transmission shaft is connected with driven wheel of differential 309；309 engaged transmission of drive bevel gear 306 and driven wheel of differential； 307 inner bottom of attachment base is equipped with ratchet 310；It is keyed at the top of 310 bottom of ratchet and transmission shaft 308；Ratchet 310 and connection Seat 307 is connected by the first deep groove ball bearing 302；310 inner peripheral of ratchet is provided with ratchet 311；It is equipped in the middle part of ratchet 310 Turntable 312；The uniform shaft in 312 periphery of turntable is connected with multiple ratchets 313；313 side of pawl and turntable 312 pass through tension spring 304 Connection；Pawl 313 and ratchet 311 are clamped；312 top center position of turntable is provided with axle sleeve 314；Axle sleeve 314 and attachment base 307 It is connected by the second deep groove ball bearing 303；Spacer is installed between first deep groove ball bearing 302 and the second deep groove ball bearing 303 315；307 inner tip of attachment base is equipped with circlip 316；It is clamped at the top of tension spring 304 and the second deep groove ball bearing 303；4 spiral shell of motor Silk is fixedly mounted on 307 top of attachment base；4 shaft end of motor and axle sleeve 314 are keyed.

In use, step 1 starts motor 4, motor 4 is rotated clockwise to be driven by axle sleeve 314 in conjunction with shown in Fig. 1-4 Turn be clockwise pivoted, when turntable 312 rotates clockwise drive periphery pawl 313 rotate synchronously, pawl 313 rotate when with Ratchet 311 inside ratchet 310 is mutually clamped, and motor 4 continues to rotate, to drive 310 up time of ratchet indirectly by pawl 313 Needle rotation；Because driven wheel of differential 309 and ratchet 310 are keyed with transmission shaft 308 respectively, so ratchet 310 passes through transmission shaft 308 Driven wheel of differential 309 is driven to rotate clockwise, 306 engaged transmission of driven wheel of differential 309 and drive bevel gear, driven wheel of differential 309 drive drive bevel gear 306 to rotate, to realize that motor 4 drives the input shaft 101 of speed reducer 1 to rotate；Drive bevel gear It drives the driven wheel of differential 309 of two sides to rotate synchronously while 306 rotation, drives the ratchet 310 of two sides suitable by transmission shaft 308 Hour hands rotation, because other two motors 4 do not work, turntable 312 is fixed under the action of axle sleeve 314, and ratchet 310 is rotating During by ratchet 311 push pawl 313 rotate clockwise, compressed spring 304 when pawl 313 rotates clockwise, currently Pawl 313 rebounds under the action of 304 elastic force of spring when ratchet 311 is moved through pawl 313；So ratchet 310 rotates clockwise It not will drive other two motors 4 to rotate, be equivalent to rotation axis and 4 axis of motor is detached from, substantially reduce the resistance of work drive motor 4.

Step 2, in conjunction with shown in Fig. 1-4, according to different operating environment (when the power provided needed for equipment running and work Between) working condition for controlling three motors 4 is corresponded to, energy conservation that work efficiency is high solves 4 power of pump truck and blender work drive motor Larger, when blender raw material are less and when pump truck stock height is lower, motor 4 still operates not energy-efficient ask with higher-wattage Topic；If one of failure of motor 4 needs repairing in the course of work, other motors 4, only need to be by event without stopping working Barrier motor 4 is repaired from being correspondingly connected with to disassemble on seat 307, can be passed through plc when working long hours and be controlled three Motor 4 works alternatively, and 4 failure rate of motor is low, and device remains to operate normally when one of motor 4 breaks down, and solves electricity The problem of 4 long-time high-power operation of machine, high failure rate influences the progress of work；When equipment resistance is larger, three motors 4 are simultaneously Power is provided for speed reducer 1, shares resistance jointly, speed reducer 1 exports revolving speed and is basically unchanged, solves raw material and excessively cause to stir Resistance becomes larger, and the common load of decelerating motor 4 higher rotation speed is slack-off, and mixing quality reduces probably damages asking for motor 4 sometimes Topic；The control mode of the utility model is automatically controlled by controller, the skill that the control circuit of controller passes through this field Art personnel's simple programming can be realized, and belong to the common knowledge of this field, and the utility model is mainly used to protect mechanical dress It sets, so the utility model is not explained control mode and circuit connection.

It should be understood that the above-mentioned specific embodiment of the utility model is used only for exemplary illustration or explains this reality With novel principle, without constituting limitations of the present invention.Therefore, in the spirit and scope without departing from the utility model In the case of any modification, equivalent substitution, improvement and etc. done, should be included within the scope of protection of this utility model.In addition, The appended claims for the utility model are intended to cover to fall into attached claim scope and boundary or this range and boundary Whole change and modification in equivalent form.
