Abstract
The utility model disclose a control mechanism of a discharging door of a mixer, comprising an air cylinder, a driving rocker, a connecting rod, a driven rocker and a discharging door. The discharging door is fixedly connected with a rotating shaft by a supporting arm; one end of the driven rocker is also fixed with the rotating shaft and the other end thereof is hinged with one end of the connecting rod; the other end of the connecting rod is hinged with the driving rocker; the driving rocker is also hinged with a fixing seat fixed on a machine body and an expanding end of a piston rod of the air cylinder; the cylinder body of the air cylinder is hinged on the machine body; the utility model is characterized in that the connecting rod is fixedly provided with a limiting block; when the discharging door is positioned at two limiting positions of opening or closing, the different parts of the limiting block are attached on the driving rocker so as to limit the driving rocker to rotate continuously, thus effectively preventing the continuous motion of the discharging door, and guaranteeing the normal work of the mixer. Therefore, the limiting mechanism is arranged on the connecting rod instead of the machine body, thus being capable of avoiding the opening and closing of the discharging door by more times from causing the deformation of the machine body, simplifying the structure and reducing the manufacturing cost of the equipment.
Description
Technical field
The utility model relates to the mixing apparatus in the grain machinery field, relates in particular to the discharge door controlling organization of mixer.
Background technology
In the prior art, the discharge door controlling organization of the mixer in the grain feed mechanical field comprises cylinder, drive crank, connecting rod, driven rocking bar and discharge door, discharge door is fixedlyed connected with a rotating shaft through trailing arm, rotating shaft is fixedlyed connected with an end of driven rocking bar, one end of the other end of driven rocking bar and connecting rod is hinged, the other end of connecting rod is connected with an end of drive crank, the other end of drive crank is hinged on the holder of fixing with fuselage, the cylinder body of cylinder is hinged on the fuselage, and the piston rod external part and the drive crank of cylinder are hinged; Fuselage is provided with the mechanical position limitation parts.Open or be closed to when making any of drive crank, driven rocking bar and connecting rod contact with limiting component when discharge door, limiting component will limit its continuation and move, thereby reach spacing purpose.Its weak point is mechanism's complexity, and manufacturing cost is higher.Because limiting component is arranged on the fuselage, the discharge door multiple switching causes frame deflection easily.
Summary of the invention
The utility model is intended to solve mixer discharge door controlling organization mechanism complexity in the prior art, manufacturing cost height, can causes the defective of frame deflection, a kind of new mixer discharge door controlling organization is provided, make it simple in structure, easy to adjust, and reduce manufacturing cost.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
A kind of mixer discharge door controlling organization, comprise cylinder, drive crank, connecting rod, driven rocking bar and discharge door, discharge door is fixedlyed connected with a rotating shaft through trailing arm, one end of driven rocking bar is also fixedlyed connected with this rotating shaft, one end of the other end of driven rocking bar and connecting rod is hinged, place in the middle of three place's hinge point of the other end of connecting rod and drive crank is hinged, other two place's hinge point of drive crank are, one place is hinged with the holder that is fixed on the fuselage, another place is that the piston rod external part with cylinder is hinged, the cylinder body of cylinder then is hinged on the fuselage, be characterized in: be fixed with a limited block on the described connecting rod, when discharge door was closed or opened, the different parts of described limited block abutted on the drive crank, and the restriction drive crank is rotated further.
Further, above-mentioned mixer discharge door controlling organization, wherein, described limited block is L-shaped, and when discharge door was in closed condition, a side of drive crank abutted on the side of an arm of this L shaped limited block; When discharge door is in opening, conflict on drive crank in the end of an arm of L shaped limited block, and simultaneously, conflicting on driven rocking bar in the end of another arm, makes the discharge door opening more stable.
During the utility model work, cylinder drives drive crank and rotates, and the drive crank drivening rod rotates, and connecting rod drives driven rocking bar and rotates, and makes discharge door open or close.When discharge door was in two extreme positions opening or close, limited block all can effectively stop the continuation campaign of discharge door, thereby guaranteed the operate as normal of mixer discharge door.Compared with prior art, the utility model is arranged on position-limit mechanism on the connecting rod, rather than is arranged on the fuselage, the frame deflection that can avoid the discharge door multiple switching to cause, but the while simplified structure reduces the device fabrication cost.
Description of drawings
Fig. 1, discharge door of the present utility model is in the closed condition structural representation;
Fig. 2, discharge door of the present utility model is in the opening structural representation.
The implication of each Reference numeral is among the figure:
The 1-holder, the 2-drive crank, the 3-limited block, the 4-connecting rod,
The driven rocking bar of 5-, the 6-rotating shaft, the 7-trailing arm, the 8-discharge door,
The 9-cylinder, the 10-fuselage.
The specific embodiment
A kind of mixer discharge door controlling organization, as depicted in figs. 1 and 2, comprise cylinder 9, drive crank 2, connecting rod 4, driven rocking bar 5 and discharge door 8, discharge door 8 is fixedlyed connected with a rotating shaft 6 through trailing arm 7, rotating shaft 6 is fixedlyed connected with an end of driven rocking bar 5, one end of the other end of driven rocking bar 5 and connecting rod 4 is hinged, the other end of connecting rod 4 is connected with an end of drive crank 2, the other end of drive crank 2 is hinged on the holder of fixing with fuselage 10 1, the cylinder body of cylinder 9 is hinged on the fuselage 10, the piston rod external part and the drive crank 2 of cylinder 9 are hinged, and make and form three place's hinge point on the drive crank 2 altogether.Simultaneously, be set with a limited block 3 on the connecting rod 4, described limited block 3 is L-shaped; When discharge door 8 was closed or opened, the different parts of described limited block 3 abutted on the drive crank 2, and restriction drive crank 2 is rotated further.
During work, cylinder 9 drives drive crank 2 and rotates, and drive crank 2 drivening rods 4 and limited block 3 rotate together, and connecting rod 4 drives driven rocking bar 5 and rotates, and makes discharge door 8 open or close.When discharge door 8 was in two extreme positions opening or close, limited block 3 all can effectively stop the continuation campaign of discharge door 8, thereby guaranteed the operate as normal of mixer discharge door 8.When discharge door 8 was in closed condition, as Fig. 1, a side of drive crank 2 abutted on the side of an arm of L shaped limited block 3, guarantees the discharge door sealing; When discharge door 8 was in opening, as Fig. 2, conflicted on drive crank 2 in the end of an arm of described L shaped limited block 3, simultaneously, conflicting on driven rocking bar 5 in the end of another arm, makes drive crank 2 and driven rocking bar 5 all can not rotate, and discharge door 8 openings are more stable.
The utility model has good application prospects at the grain feed mechanical field.Mixer in this field in use, its discharge door switch is very frequent, adopts this design can avoid the limiting component of discharge door switch is arranged on the defective that causes frame deflection above the fuselage.And this mechanism itself designs relatively rationally, helps reducing the device fabrication cost.Limited block and connecting rod fixing more convenient, the shape of limited block can be selected and process as the case may be, and the utility model promotion and implementation better can be impelled in these aspects.
