Abstract

A building stone auto-segregation sling screen of energy saving and high efficiency is provided, which comprises a building stone screen slot, a base, a sling swing rod, an electromotor, and an eccentric machine. The building stone screen slot and the base are respectively positioned at the upper part and the lower part; the sling swing rod is positioned at the two sides, which upper and lower ends are connected with the building stone screen slot and the base respectively; the electromotor and the eccentric machine are positioned on the base at the lower section of the building stone screen slot, wherein, a pushing rod of an eccentric shaft on the eccentric machine is linked with a connecting shaft seat at the bottom of the building stone screen slot; the electromotor drive the eccentric shaft to move through a belt to make the pushing rod and the sling swing rod pushing the building stone screen slot for-and-back, thus making the building stone in the slot being threw upward and forward; sediment and stone mixed in the building stone shall drop into a sediment screen pore and a stone screen pore automatically, thus making the building stone free of impurity. The utility model is simple in structure and convenient in utilization.

Description

Building stones impurity separates the catapult sieve automatically

Affiliated technical field

The utility model relates to a kind of building stones impurity sieve, and the building stones impurity that especially consumes energy less, saves the labour separates the catapult sieve automatically.

Background technology

Railway, bridge, highway etc. construction be unable to do without the building materials building stones, and the quality of building stones quality is directly connected to the quality problems of engineering.So when gathering building stones, separating its impurity is the very important operation of a cover.At present, known building stones impurity separating device has reciprocating sieve etc., and this reciprocating sieve operation is easier, and the power that its weak point is to use is bigger, and the impurity separating effect is undesirable.Simultaneously, its structure is also complicated, the cost height.

Summary of the invention

In order to overcome existing building stones reciprocating sieve some deficiency on structure and result of use, the utility model provides a kind of building stones impurity to separate the catapult sieve automatically, this building stones impurity separates catapult sieve automatically can not only separate impurity such as silt in the building stones, fist stone automatically, and employed power is little, and required labour is few.

The technical scheme that its technical problem that solves the utility model adopts is: building stones impurity separates the catapult sieve automatically and is made up of building stones sieve groove, base, catapult rocking bar and several parts of power set.Building stones sieve groove is positioned at the top that building stones impurity separates the catapult sieve automatically, silt sieve aperture and fist stone sieve aperture are arranged in the groove, fixedly connected with it connection axle bed, silt separating tank and fist stone separating tank are arranged respectively at its bottom, the catapult rocking bar is positioned at building stones impurity and separates catapult sieve both sides automatically, its top and bottom link to each other with base with building stones sieve groove respectively, power set comprise motor and eccentric machine two partly, catch bar one end on the eccentric axle housing of eccentric machine with to be connected axle bed continuous, has driving belt to link to each other between motor and the eccentric machine by the catch bar connecting axle.When building stones transmit into building stones sieve groove, under the transmission of motor, because the axle center of eccentric shaft is to the radius length difference on axle limit, garden, thereby eccentric shaft be connected seesawing of axle bed around what axle motion had just caused that seesawing of catch bar and promotion link to each other with building stones sieve groove, make the catapult rocking bar front and back springing of building stones sieve groove both sides, causing the interior building stones of building stones sieve groove constantly up and forward to throw gets rid of, up and forward throwing in the process of getting rid of, ooze the silt and the fist stone of mixing in building stones and just fallen into silt sieve aperture and fist stone sieve aperture automatically, be discharged to silt separating tank and fist stone separating tank, make the building stones free from admixture.

The beneficial effects of the utility model are, required motor power is little, and supporting manpower is few, the automatic good separating effect of impurity.Simple in structure, easy to use.

Fig. 1 is the utility model right side apparent structure figure.

Fig. 2 is the left side apparent structure figure of the utility model embodiment.

Among the figure 1, base, 2, the catapult rocking bar, 3, building stones sieve groove, 4, fist stone sieve aperture, 5, the silt sieve aperture, 6, eccentric shaft, 7, eccentric machine, 8, catch bar, 9, driving belt, 10, motor, 11, catch bar connecting axle, 12, connect axle bed, 13, the silt separating tank, 14, fist stone separating tank.

The specific embodiment

In Fig. 1, building stones impurity separates the catapult sieve automatically by building stones sieve groove (3), base (1), several parts of catapult rocking bar (2) and power set are formed, building stones sieve grooves (3) are positioned at the top that building stones impurity separates the catapult sieve automatically, silt sieve aperture (5) and fist stone sieve aperture (4) are arranged in the groove, the connection axle bed (12) that is fixedly linked is with it arranged respectively at its bottom, silt separating tank (13) and fist stone separating tank (14), base (1) is positioned at the bottom that building stones impurity separates the catapult sieve automatically, catapult rocking bar (2) is positioned at the both sides that building stones impurity separates the catapult sieve automatically, its top and bottom link to each other with base (1) with building stones sieve grooves (3) respectively, and motor (10) and eccentric machine (7) are positioned on the base (1) of building stones sieve grooves (3) bottom.

In the embodiment shown in Figure 2, have driving belt (9) to link to each other between motor (10) and the eccentric machine (7), the other end of the catch bar (8) that links to each other with eccentric shaft (6) shell by catch bar connecting axle (11) with to be connected axle bed (12) continuous.
