The discharge door device has the characteristics of simple structure and operating reliability.

Description

A kind of discharge door mechanism

Technical field

The utility model belongs to the construction machinery equipment technical field, especially relates to a kind of concrete mixing plant powder bucket Dump gate switching device that is used for.

Background technology

Butterfly valve apparatus is adopted in present domestic concrete mixing plant powder bucket discharging, generally adopts the powder bucket below that butterfly valve is installed, and drives valve plate by cylinder and is rotated, when valve plate is in plumbness; Be door opening state, get final product discharging, when valve plate is in level, be the state of closing the door; This device is to realize sealing through the cylindrical of valve plate with cooperating of inwall, and is easy to wear after use after a while, can produce the gap; The situation of material occurs leaking, on the other hand, big particle diameter foreign matter is often arranged in the powder; Be easy to cause bin gate to be stuck, the material phenomenon takes place to leak, influence weighing precision.

Summary of the invention

The purpose of the utility model is to improve the deficiency of prior art and a kind of discharge door mechanism of simple in structure, reliable operation is provided.

The purpose of the utility model is to realize like this; A kind of discharge door mechanism is made up of the support that is fixed on the hopper top, is characterized on support, being fixed with cylinder; Be fixed with piston on the axle of cylinder; Be connected with axle between flange and the piston, be fixed with rubber ring on the flange, rubber ring can be sealed the hopper mouth.

In order further to realize the purpose of the utility model, can be in the hopper mouth, to be provided with to have the fixed disk that leaks the material mouth, guide post is fixed on the lower end of axle and can in fixed disk, slides.

Compared with present technology the utility model has following distinguishing feature and good effect: the utility model is provided with door shaped stent above hopper, is used to install cylinder, is connected with axle between cylinder and flange, the rubber ring; When cylinder piston stretched out, rubber ring moved down, and arrived in the discharge port; Be in the state of closing the door this moment, when cylinder piston shrinks, moves on the rubber ring; Be in door opening state this moment, on the fixed disk in the discharge port material spilling hole arranged, powder is through the material spilling hole discharging; Drive rubber ring through cylinder and move up and down, avoided the big particle diameter foreign matter in the powder to block Dump gate and the problem of leaking material, guaranteed weighing precision; After the rubber ring wearing and tearing, can be convenient for changing, save maintenance cost; In the hopper mouth, be provided with to have and leak the fixed disk of expecting mouth, guide post is fixed on the lower end of axle and can in fixed disk, slides, and play the guiding role, and has improved the reliability of Dump gate work.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is explained further details.

Fig. 1 is a kind of structural representation of the utility model.

Fig. 2 is the another kind of structural representation of the utility model.

Fig. 3 is a kind of structural representation of the utility model fixed disk.

The specific embodiment

Embodiment 1, and a kind of discharge door mechanism is with reference to Fig. 1; Be that upper fixed at hopper 1 has support 2, on support 2, be fixed with cylinder 3, be fixed with piston 4 on the axle of cylinder 3; Be connected with axle 5 between flange 10 and the piston 4; Be fixed with rubber ring 6 on the flange 10, rubber ring 6 can be sealed hopper mouth 8, and this has constituted a kind of structure of the utility model.

Embodiment 2, and a kind of discharge door mechanism with reference to Fig. 2, Fig. 3, is at embodiment 1 and on the basis, in hopper mouth 8, are provided with to have the fixed disk 7 that leaks material mouthful, and guide post 9 is fixed on the lower end of axle 5 and can in fixed disk 7, slides, and other and embodiment 1 are identical.
