In the technical field of dust suppression vehicles, the inventor of the application finds that because a spraying machine is usually arranged at the tail of a vehicle, the gravity center of the spraying machine is unstable during operation under the action of the gravity of the spraying machine, and the phenomenon of jumping is easy to occur; meanwhile, in order to ensure the swinging working space of the sprayer during operation, the whole length of the dust suppression vehicle in the front-back direction is longer, and the dust suppression vehicle is not beneficial to operation in narrow places.

In view of this, the embodiment of the present disclosure provides a dust suppression vehicle, as shown in fig. 1 to 4, the dust suppression vehicle includes a chassis 5 and a sprayer 2, a storage space 4 for storing the sprayer 2 is provided at a middle position of the chassis 5, the sprayer 2 includes a spray can 21, a first driving mechanism 22 for driving the spray can 21 to move in an up-down direction of the dust suppression vehicle, and a second driving mechanism 23 for driving the spray can 21 to rotate around the up-down direction, the first driving mechanism 22 can drive the spray can 21 to extend out of the storage space and is located above a roof of the dust suppression vehicle, so that the second driving mechanism 23 can drive the spray can 21 to rotate, and the first driving mechanism 22 can also drive the spray can 21 to retract into the storage space 4.

It should be understood that the roof of the dust suppression vehicle refers to the top of each functional component mounted on the chassis 5 of the dust suppression vehicle, for example, the power source 1, the liquid storage tank 3, etc. may be mounted on the chassis 5 of the dust suppression vehicle, and therefore, the roof may refer to the top of the power source 1 or the top of the liquid storage tank 3. The central position of the chassis 5 is a position within a certain length range in the central portion of the dust suppression vehicle in the front-rear direction, for example, a position located between the rear of the cab and the front of the tail unit, and the central position is only in the front-rear direction of the dust suppression vehicle, but is not limited to this.

According to the above-described structural features, when the spray can 21 is required to perform a spraying operation, for example, the operation state of the sprayer 2 can be referred to. In the working state, the first driving mechanism 22 can drive the spray cylinder 21 to ascend and extend out of the storage space 4 so as to be positioned above the roof (for example, the liquid storage tank 3) of the dust suppression vehicle, and at the moment, the spray cylinder 21 can be driven to spray for dust suppression; it should be understood that the sprayer 2, in the operating condition, can have a plurality of operating modes: in one example, the second driving mechanism 23 can drive the nozzle 21 to rotate to a specific orientation for directional dust suppression; in another example, the second driving mechanism 23 can drive the nozzle 21 to continuously rotate 360 degrees in a full angle or rotate back and forth within a preset angle range, so as to realize dynamic spraying dust suppression operation in all-directional areas or specific-directional areas of the dust suppression vehicle; the skilled person in the art can carry out the flexibility according to the actual conditions in construction field and set up different mode, and this disclosure does not put any restriction to this.

Through the technical scheme, the storage space 4 for storing the sprayer 2 on the dust suppression vehicle in the embodiment of the disclosure is arranged in the middle of the chassis 5, that is, the sprayer 2 is arranged on the dust suppression vehicle in the front-back direction of the dust suppression vehicle and is closer to the gravity center of the whole dust suppression vehicle, so that the vibration amplitude of the sprayer 2 can be reduced when the sprayer 2 works, and the jumping phenomenon of the sprayer 2 during working can be improved.

Moreover, the sprayer 2 in the embodiment of the present disclosure has an operating state and a storage state. In the working state, the spray cylinder 21 extends out of the storage space 4 and is positioned above the roof of the dust suppression vehicle, and the roof can provide a large working space for the spray cylinder 21, so that the rotation or swing of the spray cylinder 21 during working (for example, the rotation or swing within a preset angle range of the spray cylinder 21 driven by the second driving mechanism 23, the pitching motion of the spray cylinder 21 driven by the third driving mechanism 25 described below, and the like) is not interfered by other components, the working freedom is high, and the space of the dust suppression vehicle can be reasonably utilized; moreover, the spraying cylinder 21 is lifted to the upper part of the roof, the operation height of the spraying machine 2 is increased, dust in a higher range is inhibited, and the dust suppression effect is improved.

In the storage state, the axis of the spray cylinder 21 extends along the left-right direction of the dust suppression vehicle and retracts into the storage space 4, so that when the size of the storage space 4 along the front-back direction of the dust suppression vehicle is designed, only the maximum diameter D of the spray cylinder 21 needs to be considered, the width W of the storage space 4 in the front-back direction of the dust suppression vehicle can be reduced as much as possible, and the length of the whole dust suppression vehicle is reduced. In addition, the height of the dust suppression vehicle can be reduced by the storage mode, and the safety of the dust suppression vehicle in the transportation process is guaranteed.

In the embodiment of the disclosure, the dust suppression vehicle may further include a cab, a power source 1, a liquid storage tank 3 and other main components, the power source 1 is used for providing power for the spraying machine 2, and the liquid storage tank 3 is used for providing the spraying liquid for the spraying machine. The storage space 4 may be disposed between the power source 1 and the liquid storage tank 3, between the cab and the power source 1, or between the cab and the liquid storage tank 3, etc., which is not limited in this disclosure. The boundary of the storage space 4 may be defined by the boundary of the structures such as the reservoir 3, the power source 1, and the chassis 5 of the dust suppression vehicle. In an arrangement example, the front boundary of the accommodating space 4 may be defined by a rear side wall of the power source 1, the rear boundary of the accommodating space 4 may be defined by a front side wall of the liquid storage tank 3, the left boundary and the right boundary of the accommodating space 4 may be defined by planes corresponding to left and right side walls of the liquid storage tank 3, the power source 1 or the chassis 5 of the dust suppression vehicle, and the upper boundary of the accommodating space 4 may be defined by a plane where the liquid storage tank 3 or a top plate of the power source 1 is located, which can be flexibly defined by those skilled in the art according to actual situations, and the disclosure is not limited thereto.

In the embodiment of the disclosure, the projection of the spray cylinder 21 in the vertical direction of the dust suppression vehicle at least partially coincides with the projection of the liquid storage tank 3 or the power source 1 in the vertical direction. Therefore, the spraying barrel 21 occupies less space in the length direction, the length of the dust suppression vehicle in the front-back direction can be reduced as much as possible, the gravity center of the dust suppression vehicle can move forwards as much as possible, the stability of the running state of the whole vehicle, the working state of the sprayer 2 and the like is improved, and the dust suppression operation of the dust suppression vehicle in a narrow place can be favorably carried out.

In the embodiment of the present disclosure, in order to reduce the overall length of the dust suppression vehicle as much as possible, as shown in fig. 1, 3 and 4, the storage space 4 may satisfy the following conditions: the width W of the housing space 4 in the front-rear direction of the dust suppression vehicle is larger than the maximum diameter D of the nozzle cylinder 21 and smaller than the length L of the nozzle cylinder 21. The nozzle 21 is usually formed as a tapered cylinder, such as a trumpet shape that tapers or expands from the nozzle end to the nozzle opening, so the width W of the storage space 4 is designed with reference to the maximum diameter D of the nozzle 21, for example, the width W of the storage space 4 may be slightly larger than the maximum diameter D of the nozzle 21, which can satisfy the moving range of the nozzle 21 during storage and reduce the overall length L of the dust suppression vehicle as much as possible.

The disclosed embodiment implements the up-and-down movement and rotation of the nozzle cylinder 21 by the first driving mechanism 22 and the second driving mechanism 23, and an exemplary embodiment of the first driving mechanism 22 and the second driving mechanism 23 will be described in detail herein with reference to fig. 1 to 3.

Specifically, the first driving mechanism 22 includes an elevating platform 221, a guide structure 222 and a first actuating member 223, the spray cylinder 21 is disposed above the elevating platform 221, the guide structure 222 is disposed in the up-down direction and is connected to the elevating platform 221, the guide structure 222 is used for limiting the moving direction of the elevating platform 221, the first actuating member 223 is disposed below the elevating platform 221 and is connected to the power source 1, and the power source 1 is used for actuating the first actuating member 223 so that the first actuating member 223 drives the elevating platform 221 to move along the guide structure 222. The lifting platform 221 is mainly used for carrying the spray cylinder 21 and is actuated by the first actuating member 223 to drive the spray cylinder 21 to move in the up-and-down direction; the guiding structure 222 is engaged with the lifting platform 221, and is used for providing a guiding function for the lifting platform 221, so as to improve the lifting precision of the lifting platform 221.

In one embodiment of the present disclosure, the guiding structure 222 is a telescopic column, which includes at least two stages of column elements (not shown in the figure) sequentially sleeved in sequence, the upper stage column element is sleeved in the lower stage column element in an axially telescopic manner, one end of the telescopic column is fixedly connected to the chassis 5 of the dust suppression vehicle, and the other end of the telescopic column is fixedly connected to the lifting platform 221. It should be understood that there is no particular positional relationship between the upper and lower stages, for example, the upper stage column member may be located above the lower stage column member, or the lower stage column member may be located below the lower stage column member, which is not limited by the present disclosure. In addition, as for the uppermost column member, it may be a hollow column or a solid column, and the disclosure is not limited thereto.

Because one end of the telescopic upright post is fixed on the chassis 5 of the dust suppression vehicle, and the other end is fixed on the lifting platform 221, for example, the lowermost upright post element is fixed on the chassis 5, the uppermost upright post element is fixed on the lifting platform 221 and extends along the up-down direction, and the upper upright post element can axially extend and retract along the lowermost upright post element, namely, the extending and retracting direction of the upright post element is limited, thereby realizing the guiding function.

Illustratively, the guide pillar of the present disclosure may include a two-stage pillar member, wherein the lower stage pillar member is fixed on the chassis 5, and the upper stage pillar member is axially telescopically sleeved in the lower stage pillar member and fixed with the lifting platform 221 to provide a guiding function when the first actuator 223 drives the lifting platform 221 to move in the up-down direction, and wherein the length L of the two-stage pillar member is set to allow the lifting platform 221 to drive the nozzle 21 to switch between the working state and the storage state.

The cross section of the pillar member may be set according to the requirement, for example, it may be a circular section, a rectangular section or other polygonal section, which is not limited by the present disclosure.

In the embodiment of the present disclosure, the number of the guide structures 222 may be multiple, and the multiple guide structures 222 are respectively arranged along the periphery of the lifting platform 221 at intervals to limit the moving track of the lifting platform 221 from the periphery thereof, so as to improve the guiding precision. Alternatively, in other embodiments of the present disclosure, the guiding structure 222 may be single, for example, may be disposed at a central position of the lifting platform 221 for providing a guiding function for the lifting platform 221.

The guiding structure 222 of the present disclosure may also be another type of structure, for example, in another embodiment of the present disclosure, the guiding structure 222 may be a guide rail spaced around the periphery of the lifting platform 221, the guide rail is formed with a guide groove extending in the up-down direction, and the periphery of the lifting platform 221 is formed with a slider or a roller structure slidably engaged with the guide groove, so that the lifting platform 221 directionally moves through the guide groove. It should be noted here that the guide rail is not stretchable in the up-down direction, and therefore, the movement locus of the nozzle barrel 21 should be avoided when the guide rail is disposed so as to avoid mechanical interference with the nozzle barrel 21.

In the embodiment of the present disclosure, as shown in fig. 1 to 3, the first actuating member 223 is a linear driving cylinder, one end of which is hinged to the chassis 5 of the dust suppression vehicle, and the other end of which is hinged to the lifting platform 221. The hinged arrangement mode adopted by the linear driving cylinder can prevent the clamping stagnation condition caused by the fixed connection error of the linear driving cylinder relative to the arrangement mode of fixedly connecting the linear driving cylinder, thereby reducing the failure rate of the linear driving cylinder. Therefore, the lifting platform 221 in the embodiment of the present disclosure mainly achieves a smooth and precise up-and-down movement function through the cooperation of the guide structure 222 and the first actuator 223.

The first actuating member 223 may be a linear driving cylinder having various structures, and may include, for example, a cylinder body and a piston rod, one end of the piston rod is connected to the lifting platform 221 via a first hinge structure, the other end of the piston rod is telescopically inserted into the cylinder body, and the other end of the cylinder body is connected to the chassis 5 via a second hinge structure. In the embodiment of the present disclosure, the linear driving cylinder may be a hydraulic linear driving cylinder, an electric linear driving cylinder, a pneumatic linear driving cylinder, or the like, and the number of the linear driving cylinders may be one or more, which is not limited by the present disclosure.

In one embodiment of the present disclosure, the linear driving cylinder may be plural, and a plurality of linear driving cylinders are arranged at intervals below the elevating platform 221 to share the driving force of each linear driving cylinder.

In the embodiment of the present disclosure, the first driving mechanism 22 includes a lifting platform 221, the second driving mechanism 23 includes a rotating device and a second actuating element, the rotating device is rotatably disposed above the lifting platform 221, the spray nozzle 21 is disposed on the rotating device, an input end of the second actuating element is connected to the power source 1, and an output end of the second actuating element is in transmission connection with the rotating device. The rotation device is disposed above the lifting platform 221, so that the first driving mechanism 22 is prevented from being affected by the rotation, for example, after the first driving mechanism 22 drives the spray tube 21 to extend out of the storage space 4, the second driving device can continue to drive the spray tube 21 to rotate, so that the water mist can be sprayed from different angles.

In an embodiment of the present disclosure, the rotating device includes a rotating base 231 and a gear transmission system (not shown in the figures), the gear transmission system includes an input gear and an output gear, the input gear is engaged with the output end of the second actuator, the output gear is connected with the rotating base 231, for example, the output gear can be fixed on the rotating base 231, so that the second actuator can drive the rotating base 231 to rotate through the gear transmission belt. Similarly, in the disclosed embodiment, the second actuator may be a hydraulic motor, an electric motor, or the like, which is not limited by the present disclosure.

Alternatively, the rotating base 231 may be configured to be capable of rotating in a 360 ° all-around direction, or may be configured to be rotatable in a partial angular range, for example, the rotating direction may be limited to a partial angular range that allows the nozzle of the nozzle barrel 21 to face the vehicle rear direction, which is not limited by the present disclosure.

In addition, in the embodiment of the present disclosure, as shown in fig. 1 to 3, the rotating device further includes a U-shaped bracket 232 fixed on the rotating base 231, the U-shaped bracket 232 includes a bottom plate and support arms 2321 extending upward from both sides of the bottom plate, the bottom plate is fixed on the rotating base 231, and the spray can 21 is pivotally disposed between the two support arms 2321 in the up-down direction. The spray can 21 may be supported to a position spaced apart from the spin base 231 by the U-shaped bracket 232, so that a sufficient range of movement space may be provided for the spray can 21, and the support stability of the spray can 21 may be improved by the two arms 2321 supported at both sides of the spray can 21.

In an optional embodiment of the present disclosure, the sprayer 2 may further include a third driving mechanism 25, and the third driving mechanism 25 is configured to drive the nozzle 21 to perform a pitching motion in the up-down direction, so as to adjust the spraying orientation of the nozzle 21 in the up-down direction.

The third driving mechanism 25 may be a linear driving cylinder having one end hinged to the rotary base 231 and the other end hinged to the lower sidewall of the nozzle 21, and the linear driving cylinder may extend obliquely with respect to the vertical direction to push the nozzle 21 to perform a pitching motion in the vertical direction.

Like the first actuator 223 of the first driving mechanism 22, the third driving mechanism 25 may be a linear driving cylinder having various structures, for example, a cylinder body and a piston rod, one end of the piston rod is connected to the lifting platform 221 via a first hinge structure, the other end of the piston rod is telescopically inserted into the cylinder body, and the other end of the cylinder body is connected to the chassis 5 via a second hinge structure. In the disclosed embodiment, the linear driving cylinder may be a hydraulic linear driving cylinder, an electric linear driving cylinder, a pneumatic linear driving cylinder, etc., which is not limited by the present disclosure.

In combination with the first, second and third drive mechanisms 22, 23, 25, the operating conditions of the sprayer 2 can have more and more flexible operating modes.

For example, in an operating state, that is, after the first driving mechanism 22 drives the spray cylinder 21 to extend out of the storage space 4, the second driving mechanism 23 and the third driving mechanism 25 may drive the spray cylinder 21 to rotate separately or together, so that the spray cylinder 21 may perform only a rotation motion or only a pitching motion, or may perform an arbitrary curve motion formed by combining the rotation and the pitching motion, and the disclosure is not limited thereto.

For example, after the second driving mechanism 23 drives the nozzle barrel 21 to be placed in the left-right direction in the storage state, the third driving mechanism 25 may drive the nozzle barrel 21 to rotate arbitrarily in the vertical plane to provide different storage postures, for example, the nozzle orifices of the nozzle barrel 21 may be arranged in the left or right direction, may also be arranged in the upper direction, or may be arranged in the oblique upper or oblique lower direction, which is not limited by the present disclosure.

For the sprayer 2, the second driving mechanism 23 and the third driving mechanism 25 are matched, that is, the second driving mechanism 23 can drive the spray nozzle 21 to rotate around the vertical direction, and the third driving mechanism 25 can drive the spray nozzle 21 to pitch along the vertical direction, so that the spray nozzle 21 can realize multi-angle and large-range spraying work under the mutual cooperation of the second driving mechanism 23 and the third driving mechanism 25, and the dust suppression effect is improved.

Depending on the type of the first actuating member 223, the second actuating member, and the third driving mechanism 25, the power source 1 may be a variety of power sources 1 in the form of an engine, an air pump, a hydraulic station, etc., or a combination thereof, which the present disclosure does not limit.

As shown in fig. 1 and 3, in the embodiment of the present disclosure, since the working environment of the dust suppression vehicle is often a place with much dust such as house removal and soil movement, the sprayer 2 further includes a guard rail 24, and the guard rail 24 is provided at the boundary of the storage space 4 to protect the first drive mechanism 22 and the second drive mechanism 23. The guard rail 24 may be a frame structure composed of a plurality of cross members and longitudinal members, or may be a metal mesh structure to prevent road flystones or other obstacles from striking or scraping the first and second driving mechanisms 22 and 23.

Since the first driving mechanism 22 can drive the nozzle barrel 21 to move up and down, in order to prevent the guardrail 24 from interfering with the moving path of the nozzle barrel 21 during the downward movement of the nozzle barrel 21, the guardrail 24 may be lifted and lowered synchronously with the nozzle barrel 21, or the guardrail 24 may be spaced from the first driving mechanism 22 and the second driving mechanism 23, which is not limited in this disclosure.

In an exemplary embodiment of the present disclosure, the guardrail 24 is movably disposed on the chassis 5 of the dust suppression vehicle in the up-down direction, an avoiding opening for avoiding the guardrail 24 is formed on the chassis 5, a lower portion of the guardrail 24 movably penetrates through the avoiding opening, and the first driving mechanism 22 is further configured to drive the guardrail 24 to move in the up-down direction. In this way, the guard rail 24 can be prevented from interfering with the moving path of the nozzle barrel 21.

The first driving mechanism 22 comprises a lifting platform 221 and a first actuating piece 223, and the upper end part of the guardrail 24 can be fixedly connected with the lifting platform 221 and can slightly protrude out of the upper surface of the lifting platform 221 so as to protect the second driving mechanism 23; the lower end of the guardrail 24 is movably inserted into the avoiding opening, and when the first actuating member 223 drives the lifting platform 221 to move in the up-down direction, the lifting platform 221 drives the guardrail 24 to move in the up-down direction to avoid the nozzle 21. In this way, the guard rail 24 can be placed against the periphery of the lifting platform 221 to reduce the overall size of the sprayer 2.

Optionally, in one embodiment of the present disclosure, the guardrail 24 can include an upper portion 241 for shielding the first and second drive mechanisms 22, 23 and a lower portion 242 for movably engaging the bypass opening. Wherein, the upper part 241 can be formed into a frame structure or a metal net structure, which can play a role of protection and simultaneously facilitate the observation and the maintenance of the first driving device and the second driving device; the lower portion 242 may be formed in a plate-like structure to increase the protection stability, and the lower portion 242 may be in sliding fit with the avoidance opening or in clearance fit with the avoidance opening, which is not limited by the present disclosure.

Alternatively, in the embodiment of the present disclosure, the guard rails 24 may be disposed around the side boundaries of the storage space 4, that is, the guard rails 24 include a front guard rail, a rear guard rail, a left guard rail, and a right guard rail, so as to protect the first driving mechanism 22 and the second driving mechanism 23 in all directions.
