Description

Roller scrapes sand device

Technical field

It the utility model is related to the oblique belt feeder of concrete mixing plant, and in particular to oblique belt bend pulley scrapes sand device.

Background technology

The oblique belt feeder of concrete mixing plant can be stained with many belts after belt runs a period of time on bend pulley The silt mixture brought, the projection of certain altitude is formed, so as to produce abrasion to belt, and cause belt deviation, therefore needed Bend pulley is cleared up.Therefore, often lead to lose time, labor intensive.

The content of the invention

In order to solve problem above, the utility model offer one kind is simple in construction, can be carried out while work to roller What surface was cleared up scrapes sand device.

Roller described in the utility model scrapes sand device, including support base, axle, linking arm A and linking arm B, counterweight, strike-offs Plate；Support base is fixed；Axle is arranged on support base, parallel with drum shaft；Linking arm A and linking arm B are each other in certain Angle is arranged on the circumference of axle and can be around axis rotation, and counterweight and stragith edge are separately fixed at linking arm A and linking arm B end Portion；Counterweight is more than stragith edge to the torque in axle center to the torque in axle center；The periphery of roller is in the rotational trajectory of stragith edge；Scrape The periphery of sand plate end and roller touches, and roller is having angle between the section and stragith edge of stragith edge phase synapsis.

Bend pulley described in the utility model scrapes sand device, by lever principle, in the presence of counterweight, automatically adjusts and scrapes Gap between sand plate and roller, so as to reach the purpose that rolling barrel surface bonds silt.When silt cohesive force is smaller, scrape Sand plate can clean out silt；If running into the larger silt of cohesive force, when counterweight is not enough to clean out silt, pass through lever Effect, can be retained in cylinder surface by silt and work on, will not cause interruption and the damage of equipment.When operation a period of time, When stragith edge has abrasion, by leverage, stragith edge can also be adjusted to keep suitable position with roller.

The utility model is simple in construction, efficiently convenient, and silt can be cleared up while drum functions, is reduced to belt Caused abrasion and the phenomenon of sideslip, and it farthest can be adjusted between stragith edge and roller by lever principle Gap, play a part of protecting belt and equipment.

Further, the axle is fixed on support base, and linking arm A and linking arm B are integral type, are enclosed on axle.

Further, the axle is rotatably installed on support base, and linking arm A and linking arm B are fixed on axle.

Further, the fixed angle of the linking arm A, linking arm B and axle is adjustable.So as to be set according to difference Standby, Different field is adjusted.

Further, the material of the stragith edge is polyurethane or rubber.It can so reduce to roller and equipment Damage.

Further, the linking arm B for steel plate.

Further, the linking arm B, stragith edge and roller are wide.

The utility model is applicable not only on the bend pulley of the oblique belt feeder of concrete mixing plant, applies also for other field In the equipment related to roller.

Brief description of the drawings

Fig. 1 is that roller described in the utility model scrapes the structural representation that sand device coordinates with roller.

Fig. 2 is the side view that roller scrapes sand device and roller area in Fig. 1.

Each piece number explanation in figure：

1- support bases；2- counterweights；3- stragith edges；4- linking arms A；5- axles；6- bend pulleys；7- linking arms B.

Embodiment

Sand device is scraped with reference to Fig. 1 to Fig. 2 to roller described in the utility model to be described in detail.

As depicted in figs. 1 and 2, roller described in the utility model scrapes sand device and includes support base 1, axle 5, linking arm A4, matches somebody with somebody Weigh 2, stragith edge 3, linking arm B7.

The support base 1, which is fixed in frame, to be remained stationary as.

Axle 5 is arranged on 1 on support base by bearing, the axis parallel with bend pulley 6, is rotated about as miscellaneous part Fulcrum.

Linking arm A4 is two, the both ends being arranged on the length direction of axle 5, and the adjustable axle 5 that is fixed on is circumferential, each other It is parallel；Two linking arm A4 one end are fixedly connected with axle 5, and the other end is fixedly connected with counterweight 2.

Linking arm B7 is steel plate, and one end is bolted on axle 5, and the other end is fixedly connected with stragith edge 3, linking arm B7, stragith edge 3 and the width of bend pulley 6 are identical, and linking arm A and linking arm B are relative to each other on axle 5, and form obtuse angle.

The center of gravity of counterweight 2 to the distance of axle 5 and the product of the weight of counterweight 2 is more than the center of gravity of stragith edge 3 to the distance of axle 5 with strike-ofing The product of the weight of plate 3, so as in the presence of counterweight 2 stragith edge 3 be driven to be rotated around axle 2.

Bend pulley 6 is located at the side of stragith edge 3, the circumference outline of bend pulley 6 in the rotational trajectory of stragith edge 3, So as to which the end of stragith edge 3 and the periphery of bend pulley 6 touch.

Bend pulley 6 is having angle between the section and stragith edge 3 of the phase synapsis of stragith edge 3, so as to work as 6 turns of bend pulley When dynamic, stragith edge 3 can complete the silt cleaning to the periphery of bend pulley 6.

Stragith edge 3 is made up of polyurethane or rubber, and so bend pulley 6 is cleared up in silt process at it, it is possible to reduce Damage to bend pulley 6 and equipment.

The utility model design is simple and ingenious, by lever principle, in the presence of counterweight, automatically adjusts stragith edge 3 6 gap is rolled with changed course, reaches the purpose of cleaning, brings significant technique effect.

As described above, given plan content in conjunction with the accompanying drawings and embodiments, can derive similar technical scheme.But Every content without departing from technical solutions of the utility model, above example is made according to the technical essence of the utility model Any simple modification, equivalent change and modification, in the range of still falling within technical solutions of the utility model.
