Description

Technical Field

[0001] The present invention relates to the technical field of road engineering, and particularly relates to a snow melting agent spraying device. Background Art

[0002] Snowfall in winter brings many inconveniences to people's lives and transportation. Snow accumulation and icing can cause roads to be slippery, increasing the incidence of traffic accidents and seriously affecting the smooth operation of traffic. Whether it is urban roads, highways, or airport runways, bridges, etc., there is an urgent need for efficient snow removal and ice melting means. Spraying snow melting agents, as a common method to solve the problem of winter snowfall, plays an important role. It mainly lowers the melting temperature of ice and snow, prompting the snow on the road to melt quickly, thereby achieving the dredging of the road. Most snow melting agents are solid particles, and the efficiency of manually spraying snow melting agents is too low. Therefore, special snow melting agent spraying devices are used to quickly spray snow melting agents on the road.

[0003] For example, the Chinese invention patent with the publication number CN114703792B provides a road snow melting vehicle, including a vehicle body and a spreader arranged behind the vehicle body. It also includes a storage unit for carrying bagged snow melting agents, a material taking unit for transporting the bagged snow melting agents in the front-back direction of the vehicle body to the spreader, and a lifting member for enabling the bagged snow melting agents to move up and down vertically. Through the arrangement of the above structures, the snow melting vehicle can directly load bagged snow melting agents, and the material taking unit transports the bagged snow melting agents on the vehicle to the spreader and sprays them through the spreader.

[0004] However, most of the existing snow melting agent spraying devices can only spray on a small area of the road along the vehicle driving track, and it is not convenient to expand the spraying range without affecting the normal traffic of the road. As a result, a single road needs to be sprayed repeatedly, increasing the labor intensity of the staff and reducing the working efficiency of road snow melting. Summary of the Invention

[0056] The present invention will be further described in detail below with reference to the drawings. It is necessary to point out here that the following detailed implementation manners are only used to further illustrate the present invention and cannot be understood as limiting the protection scope of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention according to the above application content.

[0057] Embodiment:

[0058] As Figure 1 、 2 shown, the present invention provides a snow melting agent spraying device, which includes a connecting frame 11 for connecting a construction vehicle. A first track 12 is arranged on the connecting frame 11. The end of the first track 12 is hinged with a second track 13. A baffle 14 is arranged at the end of the second track 13. A receiving component connected to the second track 13 is arranged on the connecting frame 11. The second track 13 is driven to rotate along the hinge point between it and the first track 12 through the receiving component. The receiving component includes a telescopic rod 16 fixedly arranged on the lifting rod 18 and the connecting frame 11. The telescopic end of the telescopic rod 16 is provided with a driving plate 17. One end of the lifting rod 18 is hinged with the driving plate 17, and the other end is hinged with the second track 13. A spraying shell 21 is slidably arranged on the first track 12. A plurality of groups of guide wheels 25 are arranged on the spraying shell 21. All the plurality of groups of guide wheels 25 are slidably clamped inside the first track 12 and / or the second track 13.

[0059] In the initial state, multiple groups of guide wheels 25 can roll inside the first track 12 and the second track 13 to drive the spraying shell 21 to translate horizontally, so as to expand the spraying range of the snow melting agent. During construction, it is advisable to choose a time when there are fewer vehicles on the road surface as much as possible. When a vehicle needs to pass by one side of the construction vehicle, the spraying shell 21 is moved to the first track 12, and then by controlling the telescopic rod 16 to extend, the driving plate 17 is driven to rise. Thus, under the action of the lifting rod 18, the second track 13 is driven to rotate and retract along the hinge point with the first track 12 until the second track 13 rotates to be perpendicular to the first track 12, providing a driving space for vehicles on one side. It can be understood that in some embodiments, the second track 13 can be arranged on one side of the first track 12, or the second track 13 can be arranged on both sides of the first track 12. One or two groups of telescopic rods 16 can be provided to separately drive one group of the second tracks 13 to retract or drive both groups of the second tracks 13 to retract simultaneously.

[0060] As Figure 2 , 3 shown, in this embodiment, a spraying assembly is arranged inside the spraying shell 21. The spraying assembly includes a spraying wheel 22 rotatably arranged inside the spraying shell 21. A first bevel gear 23 is arranged on the spraying wheel 22. A driving motor 27 is fixedly arranged on the spraying shell 21. A second bevel gear 28 is arranged on the output shaft of the driving motor 27. The second bevel gear 28 meshes with the first bevel gear 23. A feeding pipe 24 communicates with the spraying shell 21. One end of the feeding pipe 24 communicates with a snow melting agent feeding device.

[0061] When spraying the snow melting agent, the solid granular snow melting agent can be fed into the spraying shell 21 through the snow melting agent feeding device and the feeding pipe 24, and the driving motor 27 is controlled to start. Under the meshing action of the second bevel gear 28 and the first bevel gear 23, the spraying wheel 22 is controlled to rotate, and then the snow melting agent entering the spraying shell 21 is swept out onto the ground to carry out the snow melting agent spraying work.

[0062] As Figures 3 to 7As shown, in this embodiment, a cross bar 31 is slidably arranged on the spraying shell 21. A driving mechanism for driving the spraying shell 21 to slide along the first track 12 and the second track 13 in a flush state is further arranged on the spraying shell 21. The driving mechanism includes two groups of support frames 26 fixed on the spraying shell 21. The cross bar 31 slidably penetrates through the support frames 26 along its axis. Two groups of spur gears 44 are rotatably arranged on the two groups of support frames 26. Rack bars 15 are arranged on both the first track 12 and the second track 13. The spur gears 44 are meshed with the rack bars 15. A driving cylinder 33 is rotatably arranged on the cross bar 31. After the cross bar 31 slides, the driving cylinder 33 can be connected to one of the spur gears 44 through a clutch driving component to convert the rotation of the driving cylinder 33 into driving the rotation of one of the spur gears 44. The clutch driving component includes two groups of first ratchet discs 36. The two groups of first ratchet discs 36 are respectively located at both ends of the driving cylinder 33. A third bevel gear 41 is rotatably arranged on the support frame 26. A second ratchet disc 42 is arranged on one side of the third bevel gear 41. One of the second ratchet discs 42 is meshed with one of the first ratchet discs 36. A fourth bevel gear 43 is arranged on the spur gear 44. The fourth bevel gear 43 is meshed with the third bevel gear 41.

[0063] By controlling the rotation of the driving cylinder 33 to drive the rotation of the first ratchet discs 36 at both ends thereof, at any moment, one of the first ratchet discs 36 is always meshed with one of the second ratchet discs 42, thereby converting the rotation of the driving cylinder 33 into controlling the rotation of one of the third bevel gears 41, and driving the spur gear 44 to rotate through the meshing of the third bevel gear 41 and the fourth bevel gear 43. During the rotation of the spur gear 44, the spraying shell 21 can be driven to slide horizontally along the first track 12 and the second track 13 through the meshing with the rack bar 15. The other spur gear 44 idles under the action of the rack bar 15 and does not function.

[0064] As Figure 3 、 5 As shown in Figures 6 and 7, in this embodiment, the driving mechanism further includes a linkage component arranged on the second bevel gear 28 to convert the rotation of the second bevel gear 28 into controlling the rotation of the driving cylinder 33. The linkage component includes a first synchronous pulley 29 coaxially connected to the second bevel gear 28. A second synchronous pulley 34 is rotatably arranged on the spraying shell 21. The driving cylinder 33 slidably penetrates through the second synchronous pulley 34 along its axis. The first synchronous pulley 29 and the second synchronous pulley 34 are connected by a synchronous belt 35.

[0065] During the process of starting the driving motor 27, the first synchronous pulley 29 is driven to rotate. During the rotation of the first synchronous pulley 29, the second synchronous pulley 34 can be driven to rotate under the action of the synchronous belt 35. During the rotation of the second synchronous pulley 34, the driving cylinder 33 slidably installed inside it can be driven to rotate. Even if the cross bar 31 slides, the driving cylinder 33 can still rotate continuously, so as to control the sliding of the spraying shell 21 under the action of the clutch driving assembly to expand the spraying range. In addition, it can be understood that in some embodiments, the diameter of the first synchronous pulley 29 is smaller than that of the second synchronous pulley 34 to stably transmit the power of the driving motor 27 to control the rotation of the driving cylinder 33.

[0066] As Figures 3 to 7 shown, in this embodiment, abutting plates 32 are provided at both ends of the cross bar 31. The cross bar 31 is connected to the driving mechanism through a reversing mechanism, so as to control the driving mechanism to reversely drive the spraying shell 21 to slide when the abutting plate 32 is blocked and drives the cross bar 31 to slide. The spraying shell 21 is connected to the cross bar 31, so as to apply a thrust to one group of first ratchet discs 36 after the cross bar 31 slides to make it engage with the corresponding group of second ratchet discs 42. The reversing mechanism includes a vertical rod 51 fixedly arranged on the spraying shell 21. A driving rod 52 is hinged on the vertical rod 51. One end of the driving rod 52 is connected to the cross bar 31 through a propulsion assembly to convert the swing of the driving rod 52 into driving the cross bar 31 to slide. One end of a tension spring 54 is fixedly connected to the spraying shell 21, and the other end is hinged to the middle section of the driving rod 52. The propulsion assembly includes a driving column 53 arranged at the end of the driving rod 52. A sliding frame 55 is fixedly arranged on the cross bar 31. The driving column 53 is slidably clamped in the sliding frame 55.

[0067] Under the action of the tension spring 54, the middle section of the driving rod 52 is subjected to a downward pulling force, and then a thrust in one direction is applied to the cross bar 31 through the cooperation of the driving column 53 and the sliding frame 55 to ensure that one group of first ratchet discs 36 and the corresponding group of second ratchet discs 42 are always in an engaged state. During the process of the spraying shell 21 sliding horizontally under the action of the driving mechanism, the cross bar 31 is driven to move accordingly until the abutting plate 32 abuts against one group of baffles 14. Under the action of inertia, the cross bar 31 is driven to slide in the support frame 26. During the sliding process of the cross bar 31, the driving column 53 can be pushed by the sliding frame 55 to swing along its hinge point with the vertical rod 51 to stretch the tension spring 54 until the tension spring 54 is stretched to the critical state and contracts, and then the driving rod 52 is quickly driven to rotate in the opposite direction, so that the other group of first ratchet discs 36 engage with the corresponding group of second ratchet discs 42, and the reverse rotation of the spur gear 44 can be controlled. If the second track 13 is in a flipped state, the spraying shell 21 can be controlled to slide in the reverse direction when the abutting plate 32 abuts against the main body of the second track 13, so that the spraying shell 21 can be driven to reciprocate and the spraying range can be expanded.

[0068] Specific usage method and beneficial effects of the present invention:

[0069] When in use, the device can spray the snow melting agent through the spraying shell 21 and the spraying components inside it. During the spraying process, the driving mechanism can be used to control the spraying shell 21 to slide along the first track 12 and the second track 13 in a flush state. When sliding to the end of the second track 13, the abutting plate 32 is blocked by the baffle 14. Then, the reversing mechanism can be used to control the spraying shell 21 to slide in the opposite direction, so that the spraying components can reciprocally spray the snow melting agent within a certain range, effectively expanding the spraying area. When a vehicle needs to pass or an obstacle blocks the second track 13, the receiving component can be controlled to drive the second track 13 to rotate and retract along its hinge point with the first track 12. At this time, the baffle 14 can abut against the second track 13 during the movement of the spraying shell 21, so that the spraying shell 21 can reciprocate within a small range, avoiding affecting vehicle travel. Compared with traditional spraying devices, this device can expand the spraying range, eliminating the need for a construction vehicle to repeatedly spray a single road, saving construction time and improving the working efficiency of road snow melting.

[0070] The foregoing has shown and described the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments. Based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of the present invention claimed.
