Description

Technical Field

[0001] This utility model relates to the field of de-icing and snow melting technology, and in particular to a snow melting agent nozzle for a snowplow. Background Technology

[0002] With the needs of economic development, my country's urban transportation, including railway and light rail networks, is increasing year by year. Due to its vast territory spanning a wide range of latitudes and longitudes, China experiences diverse and complex climates. High-altitude areas and northern regions often experience prolonged periods of frost, ice, and snowfall during winter, with cold spells in certain regions potentially lasting 90-150 days. Frost, ice, or snow accumulation on roads can severely impact safe transportation operations. Therefore, the design and application of automated de-icing devices are becoming increasingly important for operational management, as they mitigate the impact of frost, ice, and snow on railway lines and train operations.

[0003] Currently, in most parts of my country, winter snow and ice removal operations are still carried out by manually or mechanically spreading de-icing agents. Chinese patent application CN202120714324.7 discloses a de-icing agent spraying device for elevated bridges. It discloses a spraying frame fixedly connected to the end of a fixed pipe away from the connecting frame. The spraying frame is arc-shaped, with nozzles at its bottom. An air compressor is located on one side of the top of a movable frame, and an air delivery pipe is installed on the air compressor. The end of the air delivery pipe away from the air compressor is connected to the connecting frame. The arc-shaped spraying frame allows for a larger spraying area, covering the middle and sides of the elevated bridge surface. The nozzle arrangement ensures uniform coverage of the de-icing agent spray, thus enabling mechanized spraying operations.

[0004] In existing snowplows, the de-icing agent spraying devices have fixed nozzles and spray ranges, making it impossible to adjust the spray range and amount of de-icing agent according to different road surface snow and ice conditions. Therefore, this application proposes a de-icing agent nozzle for snowplows to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a snow-melting agent nozzle for a snowplow with an adjustable spray angle.

[0006] To solve the above-mentioned technical problems, the present invention includes a material conveying main pipe, which is provided with a plurality of discharge pipe heads along the axial direction. A curved nozzle is sleeved on the outside of the discharge pipe head. The curved nozzle is rotatably arranged relative to the discharge pipe head and is fixed to the discharge pipe head by an elastic clip.

[0007] Preferably, the elastic clips are circumferentially distributed on the side wall of the curved nozzle near the discharge pipe head. The outer side wall of the discharge pipe head is provided with an annular groove, and the annular groove is provided with a plurality of circumferentially distributed slots. The elastic clips match the slots.

[0008] Preferably, the elastic clamp includes a main column, one end of which near the discharge pipe head is a hemispherical structure, and the other end of the main column is provided with a limiting post. The side wall of the curved nozzle is provided with a receiving cavity to accommodate the main column, and the top of the receiving cavity is provided with a limiting post passing through a limiting hole. The diameter of the main column is larger than the diameter of the limiting post, and a spring is connected between the main column and the receiving cavity.

[0009] Preferably, the limiting post is fixedly connected to the limiting plate after passing through the limiting hole.

[0010] Preferably, a limiting ring is provided on one side of the main column near the hemispherical structure, and a limiting groove is provided on the inner side of the receiving cavity. The limiting groove matches the limiting ring, and the outer diameter of the limiting ring is consistent with the width of the annular groove.

[0011] Preferably, the bending angle of the curved nozzle is greater than 90° and less than 180°.

[0012] Preferably, the end of the curved nozzle away from the discharge pipe head is provided with a nozzle cover, the nozzle cover is threadedly connected to the curved nozzle, and the nozzle cover has a plurality of spray holes distributed on it.

[0013] Preferably, the discharge pipe head is equipped with a manual adjusting valve.

[0014] Preferably, both ends of the conveying main pipe are provided with flanges, and the flanges are provided with bolt holes distributed in a circle.

[0015] The beneficial effects of this utility model are as follows: This utility model inputs the de-icing agent through the conveying main pipe, and the de-icing agent is sprayed out from the curved nozzle through the discharge pipe head. The curved nozzle rotates relative to the discharge pipe head, which can adjust the spray range to adapt to road surfaces of different widths. At the same time, the rotation angle of the curved nozzle can be adjusted to increase the overlap of the de-icing agent sprayed from two adjacent curved nozzles, thereby increasing the amount of de-icing agent sprayed per unit road surface.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All directional indicators (such as up, down, left, right, front, back, etc.) in the present utility model are only used to explain the relative positional relationship and movement of each component in a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indicator will also change accordingly.

[0022] like Figure 1-4 As shown, this embodiment provides a snow-melting agent nozzle for a snowplow, including a main conveying pipe 1. The inner wall of the main conveying pipe 1 is coated with a corrosion-resistant layer to prevent corrosion of the main conveying pipe 1 by long-term use of snow-melting agent. The main conveying pipe 1 is provided with a plurality of discharge pipe heads 2 along the axial direction. The discharge pipe heads 2 are arranged at equal intervals, and a curved nozzle 3 is sleeved on the outside of the discharge pipe head 2. The curved nozzle 3 is rotatably arranged relative to the discharge pipe head 2 and is fixed to the discharge pipe head 2 by an elastic clip 4.

[0023] Furthermore, the elastic clips 4 are circumferentially distributed on the side wall of the curved nozzle 3 near the discharge head 2. The outer side wall of the discharge head 2 is provided with an annular groove 5, and several circumferentially distributed slots 6 are provided in the annular groove 5. The elastic clips 4 match the slots 6. Specifically, there are two annular grooves 5 along the axial direction of the discharge head 2, and there are thirty-six slots 6 in each annular groove 5. There are three elastic clips 4 along the axial direction of the curved nozzle 3, or they can be set to a multiple of 3. By using the engagement of the elastic clips 4 and the slots 6, the curved nozzle 3 and the discharge head 2 are fixed together. After applying external force to the curved nozzle 3, the curved nozzle 3 can be rotated.

[0024] Furthermore, the elastic clip 4 includes a main column 41. One end of the main column 41 near the discharge pipe head 2 is a hemispherical structure 42, and the slot 6 is also hemispherical. The other end of the main column 41 is provided with a limiting post 43. The side wall of the curved nozzle 3 is provided with a receiving cavity 31 to accommodate the main column 41. The top of the receiving cavity 31 is provided with a limiting post 43 passing through the limiting hole 32. The diameter of the main column 41 is larger than the diameter of the limiting post 43. A spring 44 is connected between the main column 41 and the receiving cavity 31. After the curved nozzle 3 is sleeved on the outside of the discharge pipe head 2, under the action of the spring 44, the main column 41 moves toward the discharge pipe head 2, so that the hemispherical structure 42 of the main column 41 is embedded in the slot 6, thereby fixing the curved nozzle 3. Meanwhile, after the limiting post 43 passes through the limiting hole 32, the limiting plate 45 is fixedly connected. The limiting plate 45 is fixedly connected to the limiting post 43 by bolts. The diameter of the limiting plate 45 is larger than the diameter of the limiting hole 32. The limiting plate 45 limits the axial movement of the main post 41 to prevent the main post 41 from coming out of the receiving cavity 31 under the action of the spring 44.

[0025] Furthermore, a limiting ring 46 is provided on the side of the main column 41 near the hemispherical structure 42, and a limiting groove 33 is provided on the inner side of the receiving cavity 31. The limiting groove 33 matches the limiting ring 46, and the outer diameter of the limiting ring 46 is consistent with the width of the annular groove 5. The limiting ring 46 is chamfered on the side near the hemispherical structure 42, and also chamfered on the outer wall of the outlet pipe head 2, to facilitate the insertion of the bent nozzle 3 into the outlet pipe head 2. Under the action of the spring 44, the limiting ring 46 is embedded in the annular groove 5, thereby limiting the axial direction of the bent nozzle 3 and ensuring that the hemispherical structure 42 is limited within the annular groove 5, improving installation accuracy. During actual installation, the limiting plate 45 can also be pulled by external force to retract the limiting ring 46 into the limiting groove 33, so as to facilitate the insertion of the bent nozzle 3 into the outlet pipe head 2.

[0026] Furthermore, the bending angle of the curved nozzle 3 is greater than 90° and less than 180°, so that the discharge end of the discharge nozzle can spray towards the rear of the snowplow, or the discharge end of the curved nozzle 3 can be rotated above the conveying main pipe 1 to increase the spray area.

[0027] Furthermore, the end of the curved nozzle 3 away from the discharge pipe head 2 is provided with a nozzle cover 7. The nozzle cover 7 is threadedly connected to the curved nozzle 3, and several spray holes 8 are distributed on the nozzle cover 7. The nozzle cover 7 can be replaced according to the form of the de-icing agent. For example, for granular de-icing agent, a nozzle cover 7 with larger spray holes 8 can be replaced or the nozzle cover 7 can be not used. For liquid de-icing agent, a nozzle cover 7 with smaller diameter spray holes 8 can be used.

[0028] Furthermore, a manual regulating valve 9 is provided on the discharge pipe head 2 to regulate the spray flow rate of the de-icing agent. Both ends of the conveying main pipe 1 are provided with flanges 10, and the flanges 10 are provided with circumferentially distributed bolt holes. The flanges 10 facilitate connection to the de-icing agent storage equipment. Two adjacent conveying main pipes 1 can also be connected together through the flanges 10 to increase the length of the conveying main pipe 1 to accommodate spraying on wider roads. The end of the conveying main pipe 1 can also be connected to the flanges 10 through the sealing plate 11 to seal one end of the conveying main pipe 1.

[0029] Its working principle is as follows: the de-icing agent is input through the main conveying pipe 1, and the de-icing agent is sprayed out from the curved nozzle 3 through the discharge pipe head 2. The curved nozzle 3 rotates relative to the discharge pipe head 2, which can adjust the spray range to adapt to different road widths. At the same time, the rotation angle of the curved nozzle 3 can be adjusted to increase the overlap of the de-icing agent sprayed from two adjacent curved nozzles 3, thereby increasing the spray volume of de-icing agent per unit road surface. It can adapt to snow and ice layers of different thicknesses on the road surface, without the need for manual operation and adjustment, thus improving the spraying efficiency of the de-icing agent.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
