Abstract

The utility model provides a wear-resisting discharging device for a concrete batching station. The wear-resisting discharging device comprises a concrete discharging hopper and a feeding port arranged at the lower end of the discharging hopper and is characterized in that a lining plate is positioned on the inner wall of the discharging hopper above the feeding port, a circle of the lining plate is arranged along the inner wall of the discharging hopper, and the lower end of the lining plate extends into the feeding port. Due to the lining plate, the feeding port is effectively prevented from being abraded, wear resistance of a discharging port is greatly improved, service life of the discharging port is effectively prolonged, and the problem that a construction period is delayed because of frequent maintenance of the discharging port is resolved. In addition, when the lining plate is abraded, the lining plate can be replaced to continue working. Therefore, shutdown time is effectively reduced, and maintenance cost is controlled.

Description

The wear-resisting blanking device of concrete mixing plant

Technical field

The utility model relates to a kind of blanking device, and the wear-resisting blanking device of particularly a kind of concrete mixing plant belongs to the concrete equipment technical field.

Background technology

Along with the continuous development of science and technology, the modern required concrete in construction site all is to transport to from special concrete mixing plant through concrete placement vehicle.This can not only improve efficiency of construction, guarantees construction quality, and can also reduce job site staff's labour intensity.In the practical operation of concrete mixing plant, often cause the problem of shutdown maintenance at present, bring for construction speed and production efficiency and seriously influence because of the feed opening serious wear.In addition, often change and keep in repair feed opening and bring financial burden also for concrete production side, in the prior art, although improve wear resistence at feed opening through setting up liner plate, because liner plate length is too short, it is little to cause abrasion resistance still to improve.Therefore be necessary prior art is improved.

Summary of the invention

For solving existing concrete mixing plant feed opening serious wear, cause frequent shutdown maintenance, thereby delay the problem of duration, the utility model provides a kind of concrete mixing plant wear-resisting blanking device.

The utility model is accomplished through following technical proposal: the wear-resisting blanking device of a kind of concrete mixing plant; The charging door that comprises concrete hopper and hopper lower end; It is characterized in that above the hopper inwall is positioned at charging door, being provided with liner plate; So that prevent the feed opening wearing and tearing through liner plate, and behind wear liner, only need to change liner plate and just can continue to use.

Said liner plate is provided with a week along the hopper inwall, and the liner plate lower end extends in the charging door, so that when making the concrete blanking, through directly falling into concrete placement vehicle through charging door along liner plate, prevents that charging door is worn.

Said liner plate is a high manganese steel sheet, so that increase the wearability of liner plate.

The utlity model has advantage and effect: adopt such scheme; Can prevent that effectively charging door is worn through liner plate; Improve the abrasion resistance of feed opening greatly, effectively improved the service life of feed opening, avoided frequent maintenance feed opening and the problem of the construction delay that causes.In addition, behind wear liner, only need to change liner plate and just can work on, effectively reduce downtime, controlled maintenance cost.It in fact is a desirable wear-resisting blanking device of concrete mixing plant.

Description of drawings

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

Fig. 2 is the A portion cutaway view of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done and to be further described.

Like Fig. 1, Fig. 2, the wear-resisting blanking device of the concrete mixing plant that the utility model provides comprises the charging door 2 of concrete hopper 1 and hopper 1 lower end; Above hopper 1 inwall is positioned at charging door 2, be provided with a liner plate 4, said liner plate 4 is provided with a week along hopper 1 inwall, and liner plate 4 lower ends extend in the charging door 2; And be fixed on the hopper 1 through screw 3, said liner plate 4 is a high manganese steel sheet, so that when making the concrete blanking; Through directly falling into concrete placement vehicle through charging door along liner plate; Prevent that charging door is worn, behind wear liner, only need to change liner plate and just can continue to use simultaneously.

Claims
