Description
Technical field
The present invention relates to casting sand recycling device technical field, specifically a kind of collection sand bucket cast with multi-dimensional vibration shakeout.
Background technology
Shakeout utilizes vibration and impacts the Casting Equipment that the molding sand in casting mold is separated with foundry goods.Vibratory shakeout machine is primarily of vibration main body and base two parts composition.Oscillating component framework is taken at the bottom of machine by two row's spring supportings.Shakeout vibration main body side horizontal symmetrical installs two vibrating motors.Making a concerted effort and the upper plane orthogonal of table top of exciting force, forms an elemental body structure, impel sandbox to be separated with molding sand, foundry goods is separated with molding sand, and the fragmentation of sand group.
In prior art, the domestic monomer matter vibratory shakeout machine amplitude generally adopted is less, only has 3 ~ 4mm, thus molding sand is slower with the speed be separated of foundry goods, when the foundry goods needing to be separated is more, the monomer matter shakeout that amplitude is less will reduce operating efficiency, and the collection of traditional shakeout equipment sand bucket is set together can not be split with shakeout table top, when collecting the sticky sand of the inner appearance of sand bucket or blocking, cleaning comparatively bothers, Given this, the invention provides a kind of novel collection sand bucket, the disassembly, cleaning collecting husky bucket can be realized, the defect of husky not easy to clean is glued for overcoming collection husky bucket inwall in prior art, and special collection sand bucket exit design also contributes to the output of molding sand.
Summary of the invention
In order to make up the deficiencies in the prior art, the invention provides a kind of collection sand bucket cast with multi-dimensional vibration shakeout, the disassembly, cleaning collecting husky bucket can be realized, in order to overcome in prior art collection husky bucket inwall sticky husky time, the not defect of easy to clean, meanwhile, special collection sand bucket exit design is conducive to the output of molding sand.
The technical solution adopted for the present invention to solve the technical problems is: a kind of collection sand bucket cast with multi-dimensional vibration shakeout, described collection sand bucket is positioned at below shakeout table top, and the husky bucket below of collection is provided with sand conveying device, described integrates husky bucket entirety as funnel-form, integrate Sha Dou cross section as rectangle, and the large end of the husky bucket of collection upward, small end down, thus molding sand can be good at moving downwardly to sand conveying device from Ji Shadou, the husky bucket of collection large end surrounding is provided with flange, flange is evenly provided with bolt hole, the husky bucket of collection is connected by bolt with shakeout table top, thus the husky bucket of collection is convenient to from the dismounting of shakeout table top and is installed, compared with prior art, this collection sand bucket inwall is more convenient for cleaning when sticky sand, described bolt tail is provided with double nut, making to collect husky bucket is connected more fastening with shakeout table top.
Described collection sand bucket bottom is provided with rectangle discharging opening, rectangle discharging opening surrounding is provided with baffle plate, described baffle plate is divided into left and right plate and front and rear panel, described left and right plate is vertically arrange, distance between described left and right plate is less than the width of sand conveying device upper conveyor belt, its effect is that the molding sand fallen from the husky bucket of collection is all entered in the conveyer belt of sand conveying device, avoids arbitrarily being scattered of molding sand and the recovery that causes is insufficient and the pollution of working environment; The outside crimping of described front and rear panel, the molding sand on sand conveying device conveyer belt is paved in its effect, resistance when move to the molding sand on conveyer belt in the husky bucket bottom of minimizing collection simultaneously; Described integrates husky bucket material as potassium steel, and wearability is good, improves the service life of the husky bucket of collection.
The invention has the beneficial effects as follows:
(1). a kind of collection sand bucket cast with multi-dimensional vibration shakeout of the present invention, described collection sand bucket below is provided with molding sand conveying device, is convenient to molding sand to transport shakeout, saves artificial;
(2). a kind of collection sand using multi-dimensional vibration shakeout of casting of the present invention struggles against, and the husky bucket of described collection detachably, when sand sticky in collecting sand and struggling against is serious, can collects sand bucket and dismantle, then clean it;
(3). a kind of collection sand using multi-dimensional vibration shakeout of casting of the present invention struggles against, and the baffle plate in described collection sand bucket molding sand exit is provided with crimping, can reduce the resistance to collection sand bucket bottom when molding sand moves on conveyer belt, the consumption of minimizing power of motor;
(4). a kind of collection sand bucket cast with multi-dimensional vibration shakeout of the present invention, reasonable in design, principle is simple, is convenient to promote the use of.
