Pendulum integral type concrete is prepared and is used grit sieving mechanism
Technical Field
The invention relates to a grinding device, in particular to a vibration and oscillation integrated sand and stone screening device for concrete preparation.
Background
Sandstone is commonly used in building decoration, and refers to a loose mixture of sand and gravel. Geology refers to mineral or rock particles with the particle size of 0.074-2 mm as sand, and those with the particle size larger than 2mm as gravel or breccia (the difference between the sand and the gravel is that the degree of rounding is different, and the detailed terms of conglomerate and sandstone can be seen). If the crushed stones in the sand are mostly gravel, the sand is called sand gravel. Sandstone is also known as sand in daily life.
The grit needs to screen before using, and its effect of grit of different granularity size is inconsistent, therefore needs to screen, and in prior art, work throws the grit to the screen cloth, and this kind of method efficiency is extremely low, and workman's intensity of labour is very big, and ordinary sieving mechanism is not fast and the condition of taking place stifled hole easily when screening.

As a further scheme of the invention: a spring is connected between the lower side of the fixed block and the outer sleeve rod, and the inner sliding rod penetrates through the center inside the spring.
As a still further scheme of the invention: and the left connecting rod, the right connecting rod and the transverse plate are in clearance fit.
As a still further scheme of the invention: the left side and the right side of the screening box are provided with side doors.
As a still further scheme of the invention: the screen is a 200-mesh screen.
As a still further scheme of the invention: the upper surface of base still is equipped with and connects the skip, connects the downside of skip to be equipped with the universal wheel.
As a still further scheme of the invention: the left cam and the right cam are identical in model and opposite in installation direction.
Compared with the prior art, the invention has the beneficial effects that: through the intermittent electrification and the power failure of the electromagnet, the screening box intermittently moves up and down to play a role in vibration, the screening speed is greatly improved, and meanwhile, the situation that sand and stones block holes during screening is effectively avoided; through the horizontal hunting that realizes the pendulum rod, drive screening case horizontal hunting, improve the mobility rate of the inside grit of screening case greatly, further lead to the speed that improves the screening, compare artifical screening simultaneously, labour saving and time saving more, simple structure moreover, greatly reduced manufacturing cost, the practicality is strong.

Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
Referring to fig. 1-3, a shake-swing integrated gravel screening device for concrete preparation comprises a base 1, an outer sleeve rod 2, an inner slide rod 3, a transverse plate 7, a swing rod 10, a screening box 13, a double-shaft motor 17, a left cam 18 and a right cam 19, wherein the outer sleeve rod 2 is fixedly welded on the left side and the right side of the upper surface of the base 1, the inner slide rod 3 is of a hollow structure inside the outer sleeve rod 2, the inner slide rod 3 is slidably installed inside the outer sleeve rod 2, the inner slide rod 3 is vertically upward, a fixing block 4 is welded on the upper end of the inner slide rod 3, a spring is connected between the lower side of the fixing block 4 and the outer sleeve rod 2, the inner slide rod 3 penetrates through the center inside the spring, a magnet 5 is further arranged at the lower end of the inner slide rod 3, an electromagnet 6 is arranged at the bottom of the outer sleeve rod 2, the electromagnet 6 is matched with the magnet 5, the, the front side vertical welding of stand 8 has oscillating axle 9, and oscillating axle 9 is last to rotate and is installed pendulum rod 10, and two parts are articulated respectively to have left connecting rod 11 and right connecting rod 12 about the downside of pendulum rod 10, and left connecting rod 11 and right connecting rod 12 are vertical downwards and wear out diaphragm 7 and articulate there is screening case 13, are clearance fit between left connecting rod 11 and right connecting rod 12 and the diaphragm 7, and the left and right sides of screening case 13 is opened there is side door 14, and side door 14 is used for the feeding and the ejection of compact, the bottom of screening case 13 is equipped with screen cloth 15, and screen cloth 15 is 200 meshes of screen cloth, and screen cloth 15 is used for screening the grit, the upper surface of base 1 still is equipped with connects skip 20, and the downside that connects skip 20 is equipped with the universal wheel, conveniently connects skip 20 to.
The utility model discloses a pendulum rod 10, including stand 8, support frame 16, left cam 18, right cam 19, left cam 18, right cam 19, support frame 16, the downside central point of support frame 16 puts through support fixed mounting has double-shaft motor 17, and the both ends output shaft of double-shaft motor 17 passes through the bearing and rotates and install on support frame 16, and interference fit installs left cam 18 and right cam 19 on double-shaft motor's the both ends output shaft, and left cam 18 and right cam 19's the model is the same completely but left cam 18 and right cam 19 installation opposite direction, and the excircle of left.
When the screening box works, sand to be screened is added into the screening box 13 from the side door 14, then the electromagnet 6 is intermittently electrified, when the electromagnet 6 is electrified, magnetism is generated, the electromagnet 6 generates attraction to the magnet 5 and drives the electromagnet 3 to slide downwards, so that the screening box 13 is indirectly driven to move downwards, when the electromagnet 6 is electrified, the magnetism of the electromagnet 6 disappears, the screening box 13 moves upwards under the action of the restoring force of the spring, and the screening box 13 intermittently moves upwards and downwards through the intermittent electrification and the outage of the electromagnet 6, so that the vibration effect is achieved, the screening speed is greatly improved, and meanwhile, the situation that the sand blocks holes is effectively avoided during screening; simultaneously when the screening, biax motor 17 begins work when still can circular telegram, biax motor 17 drives left cam 18 and right cam 19 and begins to rotate, because left cam 18 and right cam 19 installation opposite direction, thereby be in the condition of unilateral atress all the time to pendulum rod 10, thereby realize the horizontal hunting of pendulum rod 10, pendulum rod 10 drives screening case 13 horizontal hunting, improve the flow rate of the inside grit of screening case 13 greatly, further lead to the speed that improves the screening, compare artifical screening simultaneously, time saving and labor saving more, moreover, the steam generator is simple in structure, greatly reduced manufacturing cost, therefore, the clothes hanger is strong in practicability.
Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
