Description

A kind of double door mechanism of sandstone batch hopper

Technical field

The utility model relates to the related double door mechanism of concrete sandstone batch hopper.Further be meant viscosity greatly, moisture content is higher, out-of-shape, the Dump gate double door mechanism of the proportioning materials bucket of band impurity even band damping and amortization fiber impurity.

Background technology

In the batching of the various materials of concrete, because of multiple reason causes the whereabouts of material not smooth, or caking; Or be interrupted inhomogeneous whereabouts, or caking whereabouts or the like through vibration even after adopting manual work to draw to stir.Especially sandstone material; Owing to do not clean at real construction medium sand building stones, do not screen, cause the higher even sandstone that carry the damping and amortization fiber impurity secretly of clay content and water content also to sneak into use in a large number; The result must cause arch camber, not blanking bonds; The result who leans on the blanking of vibrator exciting is that material whereabouts amount is erratic, inhomogeneous, or the like.The material of these different characteristics will inevitably prolong the batching time, or weighing hopper (claiming bucket) is produced impact, causes scale hooper to bounce; Final result is to influence concrete to stir Production Line efficient and measuring accuracy etc., and then influences the mix quality of material.

As shown in Figure 1; Traditional Dump gate is that the simple gate plate of band arc rotarily opens discharging structure; Door-plate 31 (the door-plate shape can be an arc) is connected on the batch hopper 30 through door-hinge; The otic placode in door-plate side links to each other with cylinder 32, and the flexible drive door-plate of cylinder 32 31 rotates around door-hinge, thereby realizes the Kai Heguan of door.Restriction because of structure; Dump gate is rectangular partially structure; (general 180 ~ 220mm is wide because of the restriction of gate-width degree; 2200 ~ 2700mm is long), cause the difficult unobstructed whereabouts of sandstone that clay content and water content are higher even carry the damping and amortization fiber impurity secretly, unobstructed even high-power vibrator exciting also is difficult to make material to fall.

Therefore develop a kind of batch hopper Dump gate that can guarantee to the full extent that the complex materials blanking is smooth, and then the mechanism of raising batching mix production efficiency and measuring accuracy is imperative.

Summary of the invention

The technical problem that the utility model will solve is; Turning to open to traditional strip simple gate plate, discharge port is narrow partially, defective bigger than normal turns on the power; Design a kind of double door mechanism of sandstone batch hopper; It can make the significantly broadening of Dump gate gate-width under same structural constraint condition, smooth to guarantee the complex materials blanking, and then improves batching mix production efficiency and measuring accuracy; Can also make the reduction that turns on the power of door.

The technical solution of the utility model is; The double door mechanism of said sandstone batch hopper comprises the Dump gate that is positioned at dump skip bottom discharge mouth below and can discharging opening is closed or open; Its design feature is; Said Dump gate is formed the dual panel structure by active door-plate and driven door-plate, and respectively there is a double rocker mechanism at the two ends of said active door-plate and driven door-plate; This double rocker mechanism does, initiatively there is initiatively end plate the end of door-plate, and initiatively end plate is hinged with connecting plate through a jointed shaft; There is driven end plate the end of driven door-plate, and driven end plate is hinged with said connecting plate through another jointed shaft; The two ends of connecting rod are hinged with said active end plate and driven end plate respectively and form said double rocker mechanism; Said connecting plate is fixedly connected on the batch hopper through securing member; Actuating cylinder one end is hinged with the otic placode that is fixed on batch hopper 1, and this actuating cylinder other end is hinged with the otic placode of active door-plate.

Below the utility model made further specify.

Referring to Fig. 2 to Fig. 4, the design principle and the course of work of the utility model are that it is the dual panel structure; The end plate of each door-plate through two ends is hinged on the batch hopper; Form a double rocker mechanism through rod hinge connection between two, wherein a door-plate (initiatively door-plate) is with actuating cylinder continuous (this door-plate can be designed to be with the cylinder adapter sleeve, links to each other with actuating cylinder through adapter sleeve); Under aerodynamical effect; Flexible through cylinder piston rod drives double rocker mechanism and is attached to the swing of two door-plates on the double rocker mechanism, realizes the opening and closing of door; That is; The active door-plate that links to each other with actuating cylinder stretches along with cylinder piston and rotates around door-hinge (jointed shaft); Drivening rod is rotated in its rotation; And the rotation of connecting rod spurs the rotation of driven every plate direction different with the active door-plate around its door-hinge (jointed shaft) edge, this door that is associated rotation has synchronously realized that two door-plates are accomplished door under the drive of a power synchronous closure or openness move, a Kai Heguan who has realized.

The utility model adopts related double door Dump gate, can be convenient to Dump gate by strip the nearly tetragonal structure of discharging instead; Under same structural constraint condition, can make the broadening of Dump gate gate-width more than 60 ~ 80%.

Known that by above the utility model is a kind of double door mechanism of sandstone batch hopper, it can make the significantly broadening of Dump gate gate-width under same structural constraint condition, and is smooth to guarantee the complex materials blanking, and then improves batching mix production efficiency and measuring accuracy; Because of the improvement of structure, also can reduce turning on the power of door simultaneously.
