Description
Technical field
This utility model relates to concrete production equipment field, particularly to a kind of gravel conveyor.
Background technology
During concrete production, need to be transported to agitator tank be stirred from the place specified by fine sand, sandstone,
So in concrete manufacturing enterprise, often using gravel conveyor, gravel conveyor is to carry with electrodeless flexible conveyer belt
Fortune material continuous conveyor, conveyer belt be i.e. haulage gear be again load carrier, with rotate carrying roller support, the resistance of operation
Power is less, and drive roll rotates under the driving of motor, drives transport by the frictional force between drive roll and conveyer belt
Band runs together with the material on conveyer belt continuously, and owing to conveyer belt continuously carries, conveyer belt can produce abrasion or become
Obtain the most lax, so needing conveyer belt is carried out tensioning；General tensioning mode be by conveyer belt wherein one section be wound up into
On tight roller, rely on the balancing weight on idler roller that conveyer belt plays the effect of the power of traction downwards, but the fortune on idler roller
Defeated band can be by the whole action of gravity of balancing weight, and now conveyer belt will be by stretching of farthest extending, it is impossible to according to fortune
Defeated band lax degree each time carries out corresponding tension adjustment, conveyer belt can be caused to be eventually pulled completely and hold, it is impossible to according to reality
The border degree that relaxes correspondingly regulates.
Utility model content
The purpose of this utility model is to provide a kind of gravel conveyor, utilize governor motion to control that ballast box declines away from
From, and then the position of ballast box can be regulated according to the conveyer belt degree of relaxing the most accordingly and i.e. realize conveyer belt effective
Extension level of stretch, it is to avoid conveyer belt is stretched to maximum limit, facilitates the regulation to belt tension, and extend defeated
Send the service life of band.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of gravel conveyor,
Including frame, live-roller, idler roller and be wound in live-roller and the conveyer belt of idler roller outer wall, described frame is vertically
Slidably connecting ballast box, described ballast box is connected to idler roller, and described frame is provided with fixed pulley, and described fixed pulley is wound with pulling force
Band, described pull strap one end is connected to ballast box and the other end connects the regulation machine having for realizing controlling ballast box dropping distance
Structure.
By using technique scheme, utilize and be around in fixed pulley both sides and be connected to the pull strap of ballast box, it is possible to be right
Ballast box plays a pulling force effect upwards, it is to avoid ballast box meeting entirely due to himself pressure effect and drop to minimum
Position, and cause extend stretching maximum to conveyer belt, the ductility of conveyer belt can be impacted, thus can shorten
The service life of conveyer belt；When live-roller cannot produce the effect of power to conveyer belt, governor motion can be relied on to regulate and to join
The dropping distance of loaded van rather than directly make ballast box drop to extreme position, thus when be adjusted to conveyer belt just with transmission
Roller is conflicted and is rubbed, it is possible to during normal drive transmission, and just control ballast box cannot decline again, thus facilitates belt tension
Regulation, slow down conveyer belt abrasion speed, extend the service life of conveyer belt.
This utility model is further arranged to: described governor motion includes ratchet and pawl, and described pull strap is away from counterweight
Case one end is wound in ratchet, and described ratchet is articulated with frame and realizes the disengaging with ratchet or engagement.
By using technique scheme, when ratchet departs from ratchet, it is possible to will open due to the action of gravity of ballast box
Power roller carries out drop-down, thus changes the tensioning degree of conveyer belt, and once when conveyer belt is extended by jockey pulley, be stretched to can be just
Chang Chuandong transport time, just pawl-and-gearing is meshed, thus just the position of ballast box can be fixed, it is to avoid its understand due to
Self gravitation reason and continue to decline, wait conveyer belt upper once wear and tear time, then control ratchet by ballast box decline certain away from
From, make conveyer belt again conflict with live-roller friction, it is ensured that the normal operation of conveyer belt, click easy to operate, make
Convenient to the tension adjustment of conveyer belt.
This utility model is further arranged to: described frame is provided with motor, and described step motor drive ratchet rotates
Realize ballast box to decline.
By using technique scheme, directly utilize motor to control the number of turns of pawl wheel, and then just can make
The process more automatization of belt tension regulation is more accurate, can control the dropping distance of ballast box, make conveyer belt just
Overcome its lax degree so that it is can carry out, with live-roller, friction of conflicting, it is to avoid conveyer belt is stretched excessive length.
This utility model is further arranged to: described frame is provided with in the slide rail being vertically arranged, described idler roller and counterweight
Case is all slidably connected to slide rail, and described idler roller is rotating with slide rail.
By using technique scheme, utilize slide rail that the motion of idler roller and ballast box is carried out guide and limit, both
Can slide along vertical direction.
This utility model is further arranged to: described fixed pulley is rotationally connected with slide rail and deviates from ballast box one end.
By using technique scheme, fixed pulley is installed on the upper end of slide rail such that it is able to enter in the lower end of slide rail
Row controls the rotation of ratchet, also can limit the direction of motion of pull strap, can the riding position of more reasonably arrangement components.
This utility model is further arranged to: described ballast box is provided with placement cavity, is provided with some in described placement cavity
Balancing weight.
By using technique scheme, it is possible to utilize in ballast box cavity the weight of balancing weight to increase idler roller pair
The tensile force of conveyer belt, it is to avoid idler roller pulled down cannot be carried out tensioning to conveyer belt by less quality, has widened tune
The range of accommodation of joint mechanism, extends the service life of conveyer belt.
This utility model is further arranged to: described ballast box is provided with conveyor belt surface in the scraper plate arranged of conflicting, institute
State ballast box and be provided with the collection frame of scraper plate.
By using technique scheme, utilize scraper plate can carry out the most clear to the fine sand mudstone of conveyor belt surface residual
Removing, it is to avoid in continual transport, conveyor belt surface can accumulate fine sand mudstone；Residue is removed in time, permissible
Avoid its normal operation dropping to affect whole gravel conveyor in actuating unit in transmitting procedure；Because idler roller meeting
Conveyer belt is wound up into outside, if residue to be cleared up not in time collection, will make Certain residues drop to ground or
On ballast box, cause environmental disruption and airborne dust.
In sum, this utility model has the advantages that and combines click, fixed pulley, pull strap, counterweight
Case, it is possible to effectively control the dropping distance of ballast box, and then the idler roller tension adjustment to conveyer belt can be controlled more accurately,
Make conveyer belt only be deflected into live-roller just to conflict friction, it is to avoid conveyer belt is extended the length of its maximum stretched, thus
The service life of conveyer belt can be extended further.
