Examples

A sand supply conveyor system, as shown in fig. 1 to 5, includes a total hopper 100 and a plurality of transport devices 200;

the total hopper 100 comprises a plurality of discharge ports 110 arranged at the bottom of the total hopper 100 side by side, and a switch piece 120 capable of adjusting the opening area of the corresponding discharge port 110 is arranged outside each discharge port 110;

the conveying devices 200 are in one-to-one correspondence with the discharge ports 110, the conveying devices 200 comprise conveying belts 210, and the feeding ends of the conveying belts 210 are located below the corresponding discharge ports 110 and are used for conveying sand output by the corresponding discharge ports 110 to required storage equipment or different construction scenes.

It will be appreciated that when the aggregate hopper 100 is filled with sand and the sand is simultaneously discharged through the plurality of discharge ports 110, the smaller the opening area of the discharge ports 110, the smaller the amount of sand discharged therefrom per unit time, the larger the area of the opening area of the discharge ports 110, the larger the amount of sand discharged therefrom per unit time, i.e., the opening area of the discharge ports 110 is proportional to the discharge rate of the sand.

Based on this, through the setting of switch 120, can adjust the open area of different discharge gates 110, and then can change the output proportion of different discharge gates 110 in unit time when exporting sand simultaneously, from this, can be under knowing the prerequisite of total sand volume, carry the sand volume of storage facilities and different construction scenes to the accuse.

Specifically, when the transport vehicle for transporting the sand arrives, the total amount of the sand poured into the total hopper 100 is obtained, and as the total amount of the sand, according to the total amount of the sand and the amounts of the sand required in different scenes, different proportions of the amounts of the sand required in the different scenes to the total amount of the sand are obtained, for example, the total amount of the sand is a, the amount of the sand required in the B construction scene is B, the amount of the sand required in the C construction scene is C, and the remaining sand is transported to the storage device D, and the amount of the sand transported to the storage device D is D (where d=a-B-C), thereby adjusting the switch 120 of the three discharge ports 110 corresponding to the B construction scene, the C construction scene, and the storage device D so that the ratio of the opening areas of the three discharge ports 110 is B: c: d, thereby enabling the ratio of the sand output rates corresponding to the discharge ports 110 to be also b: c: d, after the total sand amount is finally distributed, the sand amounts required by different scenes can approximately meet the requirements.

As shown in fig. 2, the switch 120 may include a shutter 121 and a lifting device 122, where the shutter 121 is inserted into the discharge port 110 in a sliding manner along a direction perpendicular to an axis of the discharge port 110, the lifting device 122 is disposed outside the discharge port 110, and a driving end of the lifting device 122 is connected to the shutter 121, so as to drive the shutter 121 to rise or fall. The position of the flashboard 121 in the discharge hole 110 is controlled by the lifting device 122, so that the range of the discharge hole 110 which is not blocked by the clamping plate is adjusted, and the area of the range is the opening area of the discharge hole 110.

Wherein the lifting device 122 may be a telescopic cylinder.

It should be noted that, for the above-mentioned total amount of sand, the transport vehicle and the sand carried thereon are commonly weighed by using a wagon balance before the sand is transported, and the total weight is obtained, and the weight of the transport vehicle itself is subtracted, and the result is taken as the total amount of sand. However, it will be appreciated that in the event that the truck is not fully dumped, such as in wet weather, a portion of the sand is closely adhered to the truck by moisture, and the result of the total weight minus the weight of the truck itself is significantly greater than the actual total amount of sand, and therefore, in one or more embodiments, a dump platform 300 having a weighing function is provided on one side of the total hopper 100 for enabling the truck to dump the loaded sand into the total hopper 100.

Through the setting of the platform 300 of unloading that has the function of weighing, detect the weight of the transport vechicle that emptys the sand into total hopper 100 in real time, after the transport vechicle accomplished the dumping of sand, the maximum weight of the transport vechicle that obtains is weighed with the platform 300 of unloading subtracts minimum weight and is the total sand volume of dumping into total hopper 100, can improve the control precision to the sand volume of delivering to storage facilities and different construction scenes from this.

In addition, it should be noted that, in order to ensure that the total amount of sand required for different scenes can be approximately satisfied after the total amount of sand is finally distributed, the total time of the sand output from the discharge port 110 needs to be uniform, so that the amount of sand obtained for different scenes can be ensured to also conform to the corresponding ratio under the condition that the sand output rate is in a certain ratio. However, in the process of dumping the sand from the transport vehicle to the total hopper 100, the stacked total hopper 100 must form an arch structure near the dumping position of the transport vehicle, at this time, the height of the sand in the total hopper 100 is not uniform, and when the sand is output through the discharge hole 110, the discharge hole 110 near the highest point may eventually need more time to output the sand; in addition, the slow output rate of sand is more prone to accumulation around the discharge port 110, which also results in more time being required to output the sand. Thus, to avoid this, in one or more embodiments, the aggregate hopper 100 is provided with a fitting for flush with the top surface of the sand in the aggregate hopper 100.

Wherein the matching piece can be a scraper blade arranged at the position of the total hopper 100 close to the bottom, and is driven by a telescopic cylinder to stretch out and draw back along the horizontal direction, when the sand top surface is output to the corresponding height, the sand top surface is scraped to be flat through stretching, and also can be a vibration device arranged at the outer side of the total hopper 100, the vibration device is used for promoting the total hopper 100 to slightly vibrate, under the influence of vibration, the sand top surface can be promoted to be converted into a flush state from an arched state and keep the state all the time, and further, the time consistency of the final completion output of all the discharge ports 110 is ensured. In addition, the sand can be loosened to a certain extent through vibration, the sand is prevented from adhering to the surface of the total hopper 100, or the sand is adhered to form a block to be blocked at the discharge hole 110, so that the control accuracy of the sand amount conveyed to storage equipment and different construction scenes is further improved.

Wherein the vibration device may be a vibration motor 130; or two telescopic cylinders arranged at two sides of the total hopper 100, and the telescopic cylinders drive the total hopper 100 to slightly swing left and right so as to shake sand in the total hopper 100 uniformly.

In one or more embodiments, a small hopper 400 is further disposed between the discharge port 110 and the feeding end of the conveyor belt 210, and the small hopper 400 is configured to receive the sand output from the discharge port 110 and output the sand to the feeding end of the conveyor belt 210, thereby avoiding the sand from scattering outside when the sand is output from the total hopper 100 onto the conveyor belt 210, and affecting the accuracy of the amount of sand to be conveyed. Especially in the case of vibration devices.

The weight of the sand is large, and the belt 210 is fatigued and stretched under long-term use of the belt 210, so that the belt 210 is elongated, and therefore, a tensioning mechanism is required to tension the belt 210, so as to ensure that the belt 210 can transport the sand practically. Thus, in one or more embodiments, as shown in fig. 4-5, the transporter 200 further includes a frame, a rotating roller 220, and a tensioning roller 230;

the conveying belt 210 bypasses all the rotating rollers 220 and the tensioning rollers 230, the conveying belt 210 comprises a conveying part 211 and a turning part 212, the turning part 212 is arranged at the bottom side of the conveying part 211 at intervals, and the tensioning rollers 230 are positioned between the conveying part 211 and the turning part 212 and are abutted against the middle part of the turning part 212;

the rotating rod is rotationally connected with the frame body, two ends of the tensioning roller 230 are respectively rotationally connected with a sliding block 240, the sliding block 240 is slidingly connected with the frame body along a direction away from the conveying part 211, the sliding block 240 is connected with a weight box 250, and the tensioning roller 230 can apply a pulling force to the turning part 212 under the gravity of the weight box 250.

The weight box 250 always applies downward pulling force to the slider 240 and the tension roller 230 thereon, so that the tension roller 230 pulls the turning part 212, thereby tensioning the conveyor belt 210 by the tension roller 230, and the tension applied to the conveyor belt 210 is mostly converted by the pulling force.

The tensioning roller 230 is slidably connected with the frame body, and always abuts against the conveyor belt 210 under the influence of gravity, even if the conveyor belt 210 is elongated, the tensioning roller 230 falls under the influence of gravity and continues to pull the conveyor belt 210, so that the tensioning roller 230 can be ensured to always tension the conveyor belt 210, and the position of the tensioning roller 230 does not need to be artificially changed along with the elongation of the conveyor belt 210; in addition, because the tension force is mainly formed by pulling the tension roller 230 by the gravity of the weight box 250, the tension force applied by the weight box 250 can be changed by adding or subtracting the weight block 251 from the weight box 250, so that the tension force applied by the conveyer belt 210 can be adjusted, and the process is simple and quick and can be performed in the transportation process; in addition, the weight of the counterweight 251 is easy to obtain, so that the tension can be controlled more easily by being able to obtain the weight of the counterweight 251 and the counterweight box 250.

When the sand is output from the hopper and falls onto the feeding end of the conveying portion 211 of the conveying belt 210, the conveying belt 210 will be impacted, and the output of the sand is unstable due to scattered sand, so that the impact force is unstable, at this time, the conveying belt 210 will be converted into an unstable pulling force to the tensioning roller 230 under the action of the impact force, which may cause the tensioning roller 230 and the weight box 250 which are slidably connected to the frame body to shake up and down, so that the tensioning effect to the conveying belt 210 cannot be achieved. Thus, in one or more embodiments, the apparatus further comprises a support portion 260 disposed on the frame, the support portion 260 being located between the conveying portion 211 and the turning portion 212, the support portion 260 having a support surface that abuts against a bottom surface of the feed end of the conveying portion 211. For supporting the feeding end of the conveying portion 211 of the conveying belt 210, at this time, the impact force of the sand falling onto the conveying belt 210 is borne by the supporting portion 260 through the conveying belt 210, so that the shaking of the tensioning roller 230 and the weight box 250 is avoided, and the tensioning of the rest of the conveying belt 210 is ensured.

The projection range of the supporting surface projected on the conveying part 211 covers all areas where the sand falls on the conveying part 211, so that the supporting part 260 can fully bear the impact force of the sand falling on the conveying belt 210. On this basis, the area of the supporting surface can be reduced by reducing the area of the entire region where the sand falls onto the conveying portion 211 by the small hopper 400, and the specification of the supporting portion 260 can be reduced, thereby reducing the cost.

The supporting portion 260 may be a plate-shaped structure attached to the bottom of the conveying portion 211, but in consideration of the fact that the supporting surface is in close contact with the conveying belt 210, the service life of the conveying belt 210 is easily affected by the friction force between the supporting surface and the conveying belt 210, so that the friction force between the supporting surface and the conveying belt needs to be reduced as much as possible. Thus, in one or more embodiments, the support portion 260 includes a support band 261 and a plurality of support rollers 262 disposed side by side, the support rollers 262 are rotatably connected with the frame body, the support band 261 bypasses all the support rollers 262, and the top surface of the support band 261 serves as the support surface.

At this time, the supporting surface can be rotated synchronously with the conveyor belt 210 by the engagement of the supporting belt 261 and the supporting roller 262, so that the friction force between the supporting surface and the conveyor belt 210 can be reduced, and the adverse effect of the friction force on the conveyor belt 210 can be reduced.

It should be noted that the supporting band 261 need only be disposed under the region where the sand falls, the required band area is much smaller than that of the conveyor belt 210, so that a stronger band material may be selected and/or a denser supporting roller 262 may be disposed to ensure the supporting of the conveyor belt 210 by the supporting band 261, and at this time, even if the supporting band 261 is damaged or loosened, the replacement cost is much lower than that of the conveyor belt 210, and thus the arrangement of the structure is practical.

In addition, the supporting portion 260 may be provided with only a plurality of supporting rollers 262 to directly support the conveyor belt 210, but considering that a certain gap is inevitably present between the supporting rollers 262, the conveyor belt 210 cannot be supported entirely, and when sand falls on the position of the conveyor belt 210 corresponding to the gap, the conveyor belt 210 still receives a certain impact force, so that the above-mentioned matching manner of the supporting belt 261 and the supporting rollers 262 is preferable.

The foregoing description of the embodiments has been provided for the purpose of illustrating the general principles of the utility model, and is not meant to limit the scope of the utility model, but to limit the utility model to the particular embodiments, and any modifications, equivalents, improvements, etc. that fall within the spirit and principles of the utility model are intended to be included within the scope of the utility model.
