Abstract

The utility model provides an adjustable scraper mechanism characterized that: a moving plate is hinged on a fixed hinge seat of a road roller, a scraper parallel to a steel wheel is equiped on a lower end of the moving plate, where a regulating screw and a nut thereof is arranged, a fixed support having an opening corresponding to the regulating screw is provided on the other side of the fixed hinge seat. On the fixed support, a pin shaft is moveable arranged, on which lower end a spring and a lock nut are provided and on the upper end of the pin shaft, a V-shaped handle capable of regulating a screw and a nut thereof is provided. Accordingly, the problem that the operating state of the scraper is close to the steel wheel or nonoperating state leaves the steel wheel is solved to make the operation convenience. The utility model further has the advantages of simple structure, and facility for manufacturing.

Description

A kind of scraping plate mechanism of regulating

Technical field

The utility model relates to a kind of dual-steel wheel road roller that is used for road construction, especially a kind of scraping plate mechanism of regulating.

Background technology

Two steel wheel fully-hydraulic vibration rollers are widely used in China Higher level pavement construction.The scraper plate that is positioned on two steel wheels plays an important role at work, and the material that it will stick on the steel wheel is wiped off, keeps the light of steel plate.In the present product, blade structure is divided into two kinds: a kind of is to utilize the torsion of spring to make scraper plate press close to steel wheel, but can not realize and the separating of steel wheel; The another kind of bolt that adopts connects, and realizes separating of scraper plate and steel wheel by the position of adjusting bolt, but this structure operation trouble also needs special tool, inconvenience.

Summary of the invention

The utility model provides a kind of simple, convenient scraping plate mechanism regulated that has for solving the technical problem that exists in the known technology.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of scraping plate mechanism of regulating, by fixed hinged seat, the portable plate hinged with fixed hinged seat, be installed in the scraper plate parallel of portable plate lower edge with the road roller steel wheel, be installed in the adjusting screw(rod) on the portable plate, and the fixed support that is connected with adjusting screw(rod) that is packed on the fixed hinged seat is formed, be shaped on the gap corresponding on the described fixed support with the adjusting screw(rod) position, fixed support gap one side is shaped on two locating holes, the movable installation of fixed support gap opposite side lower end has the bearing pin of spring and locking nut, the upper end of bearing pin is hinged with handle rotatable and that lift, handle is in the shape of the letter V, and also is shaped on the alignment pin that the fixed support locating hole matches on the handle.

Advantage and the good effect that the utlity model has are: regulate the corresponding gap of bolt owing to have on fixed support with portable plate, on fixed support, be hinged with handle liftable and that rotate, handle is made the V font that can block the screw rod mother, also be shaped on locating hole and alignment pin on handle and the fixed support respectively, can realize the operation putting down scraper plate or lift scraper plate easily by the actuating handle, promptly reliable simply again.The utility model also has advantage simple in structure, that be easy to make in addition.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is that the B of Fig. 1 is to view.

Among the figure: 1, fixed hinged seat; 2, portable plate; 3, scraper plate; 4, nut; 5, adjusting screw(rod); 6, bolt; 7, steel wheel; 8, fixed support; 9, gap; 10, bearing pin; 11, locating hole; 12, alignment pin; 13, locking nut; 14, V-arrangement handle; 15, spring.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1, be hinged with portable plate 2 on the fixed hinged seat 1 on the road roller, the portable plate lower end is equipped with the scraper plate 3 that parallels with steel wheel 7 by bolt 6.In order to keep scraper plate to lift state, on portable plate, be fixed with adjusting screw(rod) 5, extremely nut 4, the other end of fixed hinged seat 1 is equipped with fixed support 8, corresponding adjusting screw(rod) is shaped on gap 9 on the fixed support, and support bracket fastened gap one end is movably installed with bearing pin 10, but the bearing pin upper end is equipped with the V-arrangement handle 14 of fastening portable plate adjusting screw(rod) nut, the bearing pin lower end also is equipped with spring 15 and locking nut 13, can make the V-arrangement handle lift and rotate like this.For the location of V-arrangement handle, an alignment pin 12 is installed, on the V-arrangement handle at the fixed support gap other end and the locating hole 11 that is shaped on two alignment pin correspondences.

Using method:

When 3 work of needs scraper plate, to lift V-arrangement handle 14 (bearing pin 10 has spring 15, so can lift) and be rotated counterclockwise support bracket fastened locating hole 11 interior the fixing of alignment pin 12 insertions that make on the V-arrangement handle, the V-arrangement handle is opened in nut 4 holders of adjusting screw(rod) 5, puts down scraper plate.Because the deadweight principle, scraper plate contacts with steel wheel and reaches job requirement.

When scraper plate did not need work, hand lifted scraper plate, lifted, rotates the V-arrangement handle clockwise, made the alignment pin of handle insert another locating hole, and the nut 4 of portable plate adjusted screw rod 5 is ridden on the V-arrangement handle, and scraper plate and steel wheel break away from.

Claims

1. can regulate scraping plate mechanism for one kind, by fixed hinged seat, the portable plate hinged with fixed hinged seat, be installed in the scraper plate parallel of portable plate lower edge with the road roller steel wheel, be installed in the adjusting screw(rod) on the portable plate, and the fixed support that is connected with adjusting screw(rod) that is packed on the fixed hinged seat is formed, it is characterized in that: be shaped on the gap corresponding on the described fixed support with the adjusting screw(rod) position, fixed support gap one side is shaped on two locating holes, the movable installation of fixed support gap opposite side lower end has the bearing pin of spring and locking nut, the upper end of bearing pin is hinged with handle rotatable and that lift, handle is in the shape of the letter V, and also is shaped on the alignment pin that the fixed support locating hole matches on the handle.
