Abstract
The invention provides a sand discharging hopper of a crude sand quantifying machine. The sand discharging hopper is simple in structure, capable of accurately controlling the starting and stopping of sand discharging and ensuring quantifying accuracy, good in leaking stoppage effect, high in degree of automation and more reliable. The sand discharging hopper comprises a sand discharging hopper body and is characterized in that a shell is arranged outside the sand discharging hopper body; the shell and a discharging hole of the sand discharging hopper body are provided with shaft holes; a rotating shaft is sleeved in the shell and the discharging hole after passing through the shaft holes; the end of the rotating shaft, extending out of the shell, is hinged with a rotating arm which is hinged with a piston rod of an air cylinder; the air cylinder is arranged on one side of the shell. The sand discharging hopper also comprises a rotating door suspended below the sand discharging hopper body, wherein the rotating door is fixedly connected with two ends of the rotating shaft, extending out of the sand discharging hopper body.
Description
Technical field
The present invention relates to quantitative mechanical technical field, what be specially a kind of roughing sand quantitative machine puts sand hopper.
Background technology
Precoated sand, namely sand grain surface is covered with molding sand or the core of one deck hard resin film before moulding, and precoated sand mainly adopts the selected natural siliceous sand of high-quality to be roughing sand, and adds novolac resin, and curing agent, lubricant, reinforcing agent etc. are raw material.Precoated sand moulding is used in the higher intricate casting of dimension precision requirement, one of optimum shaping materials such as automobile, tractor, hydraulic part, along with the development of domestic and international machinery industry especially automobile industry, require more and more higher to casting quality, the application that mould covers sand is more and more extensive.
When adopting hot method technique to mix precoated sand processed, first roughing sand is heated equably, subsequently warmed-up roughing sand and hard resin are added in puddle mixer and mix, need time mixed processed to mix roughing sand and resin in strict accordance with certain proportioning, accurate quantitative analysis for roughing sand is extremely important, the sand shake-out device of roughing sand dosing device is to knockout in quantitation tube, need to stop knockout in time after arriving certain amount, the plugging valves poor effect that existing sand shake-out device is arranged, the start-stop of putting sand can not be controlled in time, excessive roughing sand can be caused to enter in quantitation tube, cause quantitative inaccurate.
Summary of the invention
For the problems referred to above, what the invention provides a kind of roughing sand quantitative machine puts sand hopper, and its structure is simple, and can accurately control the start-stop of putting sand, plugging effect is good, and guarantee quantitative accuracy, automaticity is high, more reliably.
Its technical scheme is such: it comprises puts sand hopper, it is characterized in that: described in put sand hopper and be outside equipped with shell, described shell and the described discharging opening putting sand hopper are provided with axis hole, rotating shaft is loaded in described shell and described discharging opening through described shaft hole sleeve, one end that described shell is stretched out in described rotating shaft is hinged with pivoted arm, the piston rod of the hinged cylinder of described pivoted arm, described cylinder is arranged on described shell one side, the underhung of described discharging opening has rotary door, and described rotary door is fixedly connected with described rotating shaft.
It is further characterized in that: the side of described rotary door is provided with limited block;
In described rotating shaft, correspondence put sand hopper inwall on be provided with sealing ring;
The two ends that shell is stretched out in rotating shaft are set with sealing ring, are provided with blind flange outside sealing ring, and described blind flange is fixed by screws on described shell;
Described cylinder is two bar cylinders.
The invention has the beneficial effects as follows: after the roughing sand in quantitation tube arrives scheduled volume, cylinder drives the main discharging opening putting sand hopper of rotary door shutoff, it can retain unnecessary roughing sand fast, the roughing sand be trapped all by shutoff on rotary door, can not enter in quantitation tube and cause the sand in quantitation tube excessive, ensure that quantitative accuracy, next time during quantitative putting sand, cylinder drives rotary door deflection, discharging opening exposes again puts sand, the roughing sand be simultaneously trapped within rotary door can fall into quantitation tube again, avoids waste.

Fig. 1 is schematic front view of the present invention;
Fig. 2 is schematic side view of the present invention;
Fig. 3 is the close-up schematic view at the p place of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described further.
See Fig. 1, Fig. 2, Fig. 3, the present invention includes and put sand hopper 1, put sand hopper 1 and be outside equipped with shell 2, shell 2 and put sand hopper 1 discharging opening 3 on be provided with axis hole, rotating shaft 4 is loaded in shell 2 and discharging opening 3 through shaft hole sleeve, one end that shell 1 is stretched out in rotating shaft 4 is hinged with pivoted arm 5, the piston rod of the hinged cylinder 6 of pivoted arm 5, cylinder 6 is two bar cylinders, cylinder 6 is arranged on shell 1 on one side, put sand hopper 1 underhung and have rotary door 7, rotary door 7 is fixedly connected with rotating shaft 3, the side of rotary door 7 is provided with limited block 8, in rotating shaft 4, the inwall place that correspondence puts sand hopper 1 is provided with rubber seal 9, the two ends place that shell 1 is stretched out in rotating shaft 4 is provided with sealed nylon circle 10 and is fixed with blind flange 12 by screw 11.
After the roughing sand in quantitation tube (not providing in figure) arrives scheduled volume, cylinder 6 drives the main discharging opening 3 putting sand hopper 1 of rotary door 7 shutoff, it can retain unnecessary roughing sand fast, the roughing sand be trapped all is deposited on rotary door 7, can not enter in quantitation tube (not providing in figure) and cause the roughing sand in quantitation tube (not providing in figure) excessive, ensure that quantitative accuracy, next time during quantitative putting sand, cylinder 6 drives rotary door 7 to deflect, discharging opening 3 exposes puts sand again, the roughing sand 3 be simultaneously trapped within rotary door 7 can fall into quantitation tube (figure does not provide) again, avoid waste, arranging of limited block 8 can guarantee that rotary door blocks discharging opening 3 at every turn completely, prevent that cylinder moving stroke is excessive causes rotary door 7 overswing, the arranging of rubber seal 9 can prevent from putting roughing sand in sand process and reveal contaminated equipment and avoid waste simultaneously.
