Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-5 is please referred to, the utility model provides a kind of technical solution: a kind of construction plain type Sand screen, Including vertical columns 1, clump weight 2, mobile base 3, driving motor 4, double end cam 5, universal driving shaft 6, the first sieve 7, anti-guard block Plate 8, support rod 9, spacing collar 10, supporting lug 11, connecting rod 12, the second sieve 13, drainage plate 14,15 and of damping spring column Sliding rail 16 is limited, the lower section of vertical columns 1 is fixed with mobile base 3, and the inside of vertical columns 1 and mobile base 3 is embedded in Formula is equipped with clump weight 2, driving motor 4 is equipped on the left of 1 upper end of vertical columns, and driving motor 4 is interconnected with 6 phase of universal driving shaft It connects, the two sides of universal driving shaft 6 are connected separately with vertical columns 1, and the surface at 5 center of double end cam is run through by universal driving shaft 6, and double end The surface of cam 5 offers limit sliding rail 16, and the left and right sides of the first sieve 7 is provided with protective baffle plate 8, and the protective baffle plate 8 outside is equipped with support rod 9, while support rod 9 is connected with each other by the supporting lug 11 and limit sliding rail 16 of top, and first The lower section of sieve 7 is provided with the second sieve 13, and drainage plate 14 is fixed with below 7 left end of the first sieve, and the second sieve 13 is left Right two sides are equipped with protective baffle plate 8, and the protective baffle plate 8 passes through 7 left and right sides of the fixed connecting rod 12 in outside and the first sieve Protective baffle plate 8 be connected with each other, the second sieve 13 is mutually interconnected by the upper surface of the damping spring column 15 of lower section and mobile base 3 It connects.

Double end cam 5 is symmetrically arranged with 2 about the horizontal center line of the first sieve 7, and the thickness of double end cam 5 is less than The width of supporting lug 11, and the upper end of supporting lug 11 is connected together with supporting lug 11, so that 5 turns of double end cam When dynamic, double end cam 5 passes through the supporting lug 11 engaged therewith and moves down, so that double end cam 5 drives the first sieve 7 It is vibrated up and down with the second sieve 13, plays the role of screening；

First sieve 7 and the second sieve 13 are inclined setting, and the two area equation, and the net of the first sieve 7 Diameter is greater than the net diameter of the second sieve 13, and the sand of the fritter diameter on the first sieve 7 is fallen on the second sieve 13, is convenient for classifying screen Point；

Support rod 9 is symmetrical set in the two sides of the first sieve 7, and support rod 9 is flexibly connected with spacing collar 10, limit Sleeve 10 fixes support rod 9, so that support rod 9 can only be moved in vertical direction, will not move left and right, Improve the stability of the first sieve 7 vibration；

Connecting rod 12 is set as " U " font structure, and it is symmetrically arranged with 4 about the center line of the second sieve 13 altogether, Play the role of connecting the first sieve 7 and the second sieve 13, so that the first sieve 7 can drive the second sieve when moving down 13 move down；

Damping spring column 15 has 2 groups about the center line symmetrical setting of the second sieve 13, and every group of quantity is 2, and 2 15 length of damping spring column with group are different, and since the first sieve 7 and 13 structure of the second sieve are simple, are self-possessed smaller, Damping spring column 15 plays the first sieve 7 and the second sieve 13 convenient for support, carries out vibrating screen to the sand of 7 top of the first sieve Point.

Working principle: when using construction plain type Sand screen, will move integrally to beside sand drift first, Driving motor 4 is connected to external power supply later, sand is transported to the top of the first sieve 7 later, starts the electricity of driving motor 4 Source, driving motor 4 drives 2 double end cams 5 to be rotated simultaneously by universal driving shaft 6, when double end cam 5 is rotated, protrusion One section of drive supporting lug 11 move down, so that supporting lug 11 drives 7 two sides of the first sieve by the support rod 9 of lower section Protective baffle plate 8 move down, the first sieve 7 by connecting rod 12 drive the second sieve 13 move down so that the second sieve The protective baffle plate 8 of 13 two sides drives damping spring column 15 to move down, so that the generation elastic compression of damping spring column 15, while by It can only be moved up and down always in the inside of spacing collar 10 in support rod 9, thus when the sunk side of double end cam 5 and branch When supportting the connection of convex block 11, damping spring column 15 is sprung back, i.e. the first sieve 7 and the second sieve 13 move up, i.e., the first sieve Net 7 is moved up and down in the inside of vertical columns 1, with the cycle rotation of double end cam 5, the first sieve 7 and the second sieve 13 circulations move up and down, and the sand on the first sieve 7 is vibrated power and moves to left end, and block diameter is less than first The sand of 7 net diameter of sieve is fallen on the second sieve 13, and the sand block diameter on the second sieve 13 is less than 13 net of the second sieve Diameter, sand is fallen from 13 surface of the second sieve, is accumulated in the lower section of the second sieve 13, and the sand on the first sieve 7 is most It is flowed down from drainage plate 14 eventually, the sand on the second sieve 13 is flowed down from its left end, increases whole practicability.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
