Mixing drum is the core component of concrete mixer truck, and the good and bad direct relation of whipping performance the quality of car load working condition.In the transportation of concrete mixer truck, mixing drum can remain rotation, to ensure that delivered concrete can not solidify.In transportation, the rotating speed of mixing drum has material impact to concrete quality; Therefore, in order to ensure concrete quality, often need the rotating speed of mixing drum to keep constant.
Existing concrete trucd mixer adopts enclosed controlling organization to control the rotation direction of mixing drum usually, the locking positioning of enclosed controlling organization is stuck in the teeth groove of a sector rack by spring catch, thus ensure that reversal valve is in assigned position, disconnect or be communicated with the oil circuit of hydraulic motor, the rotation direction realizing controlling mixing drum controls; Concrete mixer truck causes sector rack to dislocate or displacement in the process of moving because jolting, the control lever of enclosed controlling organization changes angle, and the spool in 3-position 4-way hand-operated direction valve can move, and causes hydraulic motor irregular working; On the other hand, enclosed controlling organization also exists the shortcoming that production cost is high, complex installation process, repair density are large, enclosed controlling organization poor stability, is difficult to the duty controlling mixing drum.
Summary of the invention
For improving mixing drum stability under working conditions, safe and reliable control reversal valve, ensure the normal work of hydraulic motor, simultaneously handled easily, alleviate labor strength, the present invention proposes a kind of open type stirring drum of concrete agitating truck controlling organization.
For this reason, technical scheme of the present invention is: a kind of open type concrete mixer truck controlling organization, and comprise variable pump, hydraulic motor for driving mixing drum to operate, hydraulic motor is connected with variable pump by oil circuit, it is characterized in that:
Oil circuit is provided with 3-position 4-way hand-operated direction valve, and 3-position 4-way hand-operated direction valve is as oil circuit gauge tap, and 3-position 4-way hand-operated direction valve is fixed on vehicle frame;
Vehicle frame is provided with the open type controlling organization of 3-position 4-way hand-operated direction valve;
Described open type controlling organization comprises control lever, controls support, controls support and is fixed on outside mixing drum on vehicle frame, and control lever interts on control support, and control lever can rotate on control support; Control lever front end is connected with distance rod, and distance rod front end is connected with the operating grip of described 3-position 4-way hand-operated direction valve; On control lever cylindrical, cover has an adapter sleeve, and adapter sleeve is fixed on vehicle frame by connecting plate, and adapter sleeve is provided with screwed hole, and on screwed hole, correspondence is provided with lock-screw; By tightening lock-screw during use, lock-screw head top being pressed on control lever cylindrical, thus control lever is locked.
One for technique scheme is improved and is: described control support is made up of multiple spaced bracing frame, and each bracing frame top is provided with installing hole, and bracing frame is fixed on vehicle frame.
Operation principle:
During use, operating personnel drive distance rod to rotate by upper and lower rotation control rod, distance rod drives 3-position 4-way hand-operated direction valve operating grip to rotate, make three of 3-position 4-way hand-operated direction valve passages be positioned at different open and close states, with the forward and backward of this hydraulic control motor thus control mixing drum be in charging, discharging, stir material, stop different duties.
Beneficial effect:
The present invention by arranging 3-position 4-way hand-operated direction valve between hydraulic motor and variable pump, and at mixing drum arranged outside controlling organization, the break-make of 3-position 4-way hand-operated direction valve is controlled by controlling organization, realize the control to mixing drum duty with this, this mechanism structure is simple, easy to operate, cost of manufacture is low; By arranging lock-screw on control lever, it being locked, ensureing that in vehicle traveling process, control lever can not be covert, makes mixing drum duty constant, improving controlling organization reliability; Whole controlling organization is arranged in the outside of mixing drum, is convenient to installation and removal maintenance, reduces labor strength, improve operating efficiency, practical.
