Description

A kind of blanking equipment of burden balance

Technical field

The utility model is related to a kind of Feed Manufacturing burden balance, under more particularly to a kind of more particularly to a kind of burden balance Expect device.

Background technology

Burden balance refer to previously given mass ratio, the weighing apparatus to being carried out batching metering by several materials in title thing.With It is quite varied on the way, the batching metering of various materials is can be not only used for, it can also be used to a kind of metering of material, in the process of Feed Manufacturing In, various materials need to carry out substantial amounts of mixing, so needing to use larger burden balance.

Burden balance are typically made up of scale body, charging mechanism, shedding mechanism, electric-control system, after weighing terminates, thing to be weighed Body is entered by charging mechanism to be weighed in scale body, and the material that end will be weighed after terminating by discharging structure by weighing, which is unloaded, to be loaded into Enter next equipment.

The turnover panel upset that existing shedding mechanism typically drives circular arc using cylinder completes blanking, and turnover plate type blanking can be joined The Chinese patent of Application No. 200920170712.2 is examined, it discloses a kind of double-layer flap valve, including two valve bodies and two Pneumatic means, starter includes cylinder, handle and rotating shaft, and cylinder is fixed in air cylinder supporting structure；Air cylinder supporting structure passes through branch Frame is connected with valve body, and one end connection of handle and rotating shaft, cylinder is connected with handle, valve plate is provided with valve body, Telescopic-cylinder can To drive valve plate upset to realize blanking.

It is blanking as early as possible, it is necessary to which valve plate opens preferable completely in blanking in actual practicality；When being weighed, it is necessary to Valve plate is completely closed and holding of trying one's best is stable；But in above-mentioned double-layer flap valve, handle is hinged with cylinder, and rely solely on gas Cylinder ensures that turnover panel is maintained at required position, when being added materials during weighing into hopper, and material can be made from eminence blanking to turnover panel Into the impact of increasing, with the increase for weighing material, the weight of material is larger to the pressure of turnover panel, can in above-mentioned two situations So that turnover panel is unstable and influences to weigh and blanking effect.

Utility model content

The purpose of this utility model is to provide a kind of blanking equipment of burden balance, can be in weighing and blanking, and raising is turned over The stability of plate.

Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of blanking of burden balance Equipment, including the drive component that the turnover panel and driving turnover panel being rotatably connected in hopper are rotated, drive component include and hopper Cylinder that outer wall is hinged, affixed and stretch out the rotating shaft of hopper, one end and the affixed handle of rotating shaft with turnover panel, handle is away from rotating shaft The piston rod of one end and cylinder is hinged, and two groups of structures is provided with the outer wall of hopper identical and spacing positioned at handle both sides respectively Component, two groups of limit assemblies are abutted when turnover panel is opened and closed completely with handle respectively；Limit assembly includes being fixed in hopper Arc-shaped guide rail on outer wall, the slide unit being adapted to arc-shaped guide rail, the fixing axle being fixed on slide unit and it is set in fixing axle Multiple abutting plates；Along one end of fixing axle axis direction to the other end, abutting the length of plate gradually increases；Screw thread in fixing axle It is connected with and is rotatably connected to multiple gag lever posts abutted with slide unit on the clamp assembly for abutting plate both sides, the outer wall of hopper.
