DETAILED DESCRIPTION

[0022] The following is a combination of specific implementation cases and attached Figures 1 to 3 The present invention is further described below, but the present invention is not limited to these embodiments.

[0023] In view of the problem that conventional highway maintenance spraying devices in the prior art cannot spray snow-melting agents, if the snow-melting agents are manually sprayed on the road surface by following the maintenance vehicle, the labor intensity is high and it is difficult to ensure the uniformity of the snow-melting agents, refer to Figures 1 to 3 As shown, a highway maintenance spraying device is proposed, including a storage box 1, in which the snow-melting agent is stored in the inner cavity of the storage box 1 for standby use, a feeding port 2 is arranged at the top of the storage box 1, and the snow-melting agent is put into the inner cavity of the storage box 1 through the feeding port 2, and a first discharge channel 3 is installed on the left side of the bottom end of the storage box 1, and the bottom end of the first discharge channel 3 is connected with a discharge barrel 4, and a first discharge port 5 is opened at the bottom end of the discharge barrel 4, and a second discharge channel 6 is connected at the bottom end of the discharge barrel 4. When the first discharge channel 3, the discharge barrel 4, the first discharge port 5, and the second discharge channel 6 form an open channel, the snow-melting agent in the inner cavity of the storage box 1 can be sprayed downward, and a rotating drum 7 is rotatably embedded in the inner cavity of the discharge barrel 4, and the outer wall of the rotating drum 7 is rotatably fitted with the inner wall of the discharge barrel 4, so as to ensure that when the rotating drum 7 rotates, the snow-melting agent will not enter the space between the rotating drum 7 and the discharge barrel 4, and the outer wall of the rotating drum 7 is opened. The discharge port 8, when the second discharge port 8 rotates to the corresponding first discharge port 5, the snow-melting agent can be discharged. A first motor 9 is installed on the front side of the outer wall of the discharge barrel 4. The output end of the first motor 9 extends into the inner cavity of the discharge barrel 4 and is connected to the front side wall of the rotating drum 7. The first motor 9 is turned on to cause the rotating drum 7 to rotate along the inner wall of the discharge barrel 4, thereby realizing the intermittent position correspondence between the second discharge port 8 on the outer wall of the rotating drum 7 and the first discharge port 5; the first discharge port 5 corresponds to the position of the inner cavity of the second discharge channel 6 to ensure that the snow-melting agent can accurately enter the inner cavity of the second discharge channel 6 through the first discharge port 5 to be discharged, and the diameter of the second discharge port 8 is smaller than the diameter of the first discharge port 5. When the first discharge port 8 rotates to the first discharge port 5, the snow-melting agent at the first discharge port 8 can completely enter the first discharge port 5 to be discharged;

[0024] The specific steps for spraying the snow-melting agent are as follows: when the first motor 9 drives the rotating drum 7 to rotate to the second discharge port 8 corresponding to the inner cavity of the first discharge channel 3, the snow-melting agent in the inner cavity of the first discharge channel 3 enters the inner cavity of the rotating drum 7; as the rotating drum 7 continues to rotate, the second discharge port 8 is prompted to rotate to a position away from the first discharge channel 3; at this time, the outer wall of the rotating drum 7 rotates along the inner wall of the discharge drum 4 to prevent the snow-melting agent in the inner cavity of the first discharge channel 3 from continuously entering the inner cavity of the rotating drum 7; when the rotating drum 7 rotates to the second discharge port 8 and is aligned with the second discharge channel 6, the snow-melting agent in the inner cavity of the rotating drum 7 is discharged downward through the first discharge port 5 and the second discharge channel 6.

[0025] See also Figure 2 As shown, a reminder mechanism for reminding that the material in the inner cavity of the storage box 1 is about to run out is arranged at the bottom of the storage box 1. The reminder mechanism includes a mounting seat 10, and also includes a support rod 11 vertically mounted on the inner cavity of the mounting seat 10. The top of the support rod 11 is rotatably connected to a swing rod 12 through a pin shaft. A counterweight block 13 is arranged on the left side of the swing rod 12. The counterweight block 13 is used to ensure the balance of the storage box 1 and other components outside the storage box 1. As the amount of snow melting agent in the inner cavity of the storage box 1 gradually decreases, the storage box 1 is prompted to tilt counterclockwise under the action of the counterweight block 13. A connecting arm 14 is vertically mounted on the top right side of the swing rod 12. The counterweight block 13 prompts the swing rod 1 2 rotates, the connecting arm 14 can drive the material storage box 1 to rotate together, and the connecting arm 14 is fixedly installed at the bottom end of the outer wall of the material storage box 1. A key switch 15 is installed on the inner wall of the mounting seat 10. The key switch 15 is an existing component. In this embodiment, the key switch 15 needs to be pressed for a period of time to be powered on, so as to avoid the erroneous operation of the key switch 15 accidentally triggered by the swing rod 12 due to the bumps; in order to ensure that the key switch 15 can be accurately triggered, the installation position of the key switch 15 corresponds to the right end position of the swing rod 12, so as to ensure that the swing rod 12 rotating counterclockwise can accurately trigger the key switch 15.

[0026] In addition, see Figure 1 and Figure 2 As shown, a moving platform 21 is installed at the bottom of the mounting base 10, and a controller 16 is installed on the right side of the moving platform 21. The controller 16 is an existing component, which is a PLC controller commonly used in the market. It is a digital computing and operating electronic system specially designed for use in industrial environments. The key switch 15 is electrically connected to the controller 16. The controller 16 can process the trigger signal of the key switch 15 and issue a prompt instruction to prompt the staff that the snow melting agent in the inner cavity of the storage box 1 is about to run out.

[0027] The specific principle of realizing the reminder that the snow-melting agent is about to run out is as follows: as the amount of snow-melting agent in the inner cavity of the storage box 1 decreases, the overall weight of the storage box 1 and the components arranged on the outer wall decreases, and the swing arm 12, the connecting arm 14 and the storage box 1 are gradually tilted counterclockwise under the counterweight action of the counterweight block 13. When the amount of snow-melting agent in the inner cavity of the storage box 1 is reduced to the point where the right end of the swing arm 12 continuously touches the push switch 15 counterclockwise, the push switch 15 is triggered under the action of continuous pressing and transmits a signal to the controller 16. The controller 16 processes the signal and issues a command to remind the staff that the snow-melting agent in the inner cavity of the storage box 1 is about to run out.

[0028] See also Figure 2 As shown, the inner cavity of the storage box 1 is provided with a pushing assembly, which includes a partition plate 17 installed in the inner cavity of the storage box 1, and the partition plate 17 is parallel to the inner wall of the bottom end of the storage box 1, and through holes 18 are respectively opened on the left and right sides of the partition plate 17, and a spiral conveying rod 19 is rotatably connected between the partition plate 17 and the inner wall of the bottom end of the storage box 1, and a second motor 20 is installed on the right side wall of the storage box 1, and the output end of the second motor 20 is connected to the spiral conveying rod 19, and the snow melting agent in the inner cavity of the storage box 1 enters the space between the partition plate 17 and the bottom end of the inner wall of the storage box 1 through the through hole 18, and the spiral conveying rod 19 is driven to rotate by the turned-on second motor 20 to promote the snow melting agent to be transported to the left; the central axis of the spiral conveying rod 19 is parallel to the central axis of the partition plate 17, so as to ensure that the rotating spiral conveying rod 19 can smoothly push the snow melting agent along the space between the partition plate 17 and the inner cavity of the bottom end of the storage box 1, and avoid the situation where the pushing of the snow melting agent is blocked due to different sizes of spaces.

[0029] A handle 22 is installed on the right side wall of the moving platform 21, and universal wheels 23 are installed at the four corners of the bottom of the moving platform 21. During use, the handle 22 is pulled steadily and slowly to cause the universal wheels 23 arranged at the bottom of the handle 22 to move along the road surface.

[0030] The principle of spraying snow melting agent by a road maintenance spraying device in this embodiment is as follows:

[0031] During use, by pulling the handle 22 steadily and slowly, the universal wheel 23 provided at the bottom of the handle 22 is moved along the road surface; the deicing agent in the inner cavity of the storage box 1 enters the space between the partition plate 17 and the bottom of the inner wall of the storage box 1 through the through hole 18, and the second motor 20 is turned on to drive the spiral conveying rod 19 to rotate, so as to convey the deicing agent to the left;

[0032] The snow-melting agent pushed by the spiral conveying rod 19 is transported downward through the first discharge channel 3. When the first motor 9 drives the drum 7 to rotate to the second discharge port 8 corresponding to the inner cavity of the first discharge channel 3, the snow-melting agent in the inner cavity of the first discharge channel 3 enters the inner cavity of the drum 7. As the drum 7 continues to rotate, the second discharge port 8 is caused to rotate to a position away from the first discharge channel 3. At this time, the outer wall of the drum 7 rotates along the inner wall of the discharge drum 4 to prevent the snow-melting agent in the inner cavity of the first discharge channel 3 from continuously entering the inner cavity of the drum 7. When the second discharge port 8 is aligned with the second discharge channel 6, the deicing agent in the inner cavity of the drum 7 is discharged downward through the first discharge port 5 and the second discharge channel 6; as the drum 7 continues to rotate until the second discharge port 8 on the outer wall is separated from the second discharge channel 6 and corresponds to the first discharge channel 3 again, the deicing agent in the inner cavity of the first discharge channel 3 of the next cycle enters the inner cavity of the drum 7, and the deicing agent of the next cycle is discharged, thereby realizing intermittent and uniform spreading of the deicing agent, which can save more deicing agent than continuously discharging the deicing agent;

[0033] As the amount of snow-melting agent in the inner cavity of the storage box 1 decreases, the overall weight of the storage box 1 and the components arranged on the outer wall decreases, and the swing rod 12, the connecting arm 14 and the storage box 1 are gradually tilted counterclockwise under the counterweight action of the counterweight block 13. When the amount of snow-melting agent in the inner cavity of the storage box 1 decreases to the point where the right end of the swing rod 12 continuously touches the key switch 15 counterclockwise, the key switch 15 is triggered under the action of continuous pressing and transmits a signal to the controller 16. The controller 16 processes the signal and issues a command to remind the staff that the snow-melting agent in the inner cavity of the storage box 1 is about to run out.

[0034] The utility model can ensure the intermittent and uniform spreading of snow-melting agent, which can save more snow-melting agent than the continuous dispensing of snow-melting agent, meet the road maintenance needs and save resources at the same time, and the two states of intermittent dispensing and continuous dispensing can be flexibly adjusted, and can be flexibly used according to different road maintenance needs, and the labor intensity is lower than that of manual spraying, and the spraying of snow-melting agent is more uniform. In addition, the staff can be reminded in time that the snow-melting agent is about to run out and needs to be added in time, which makes it more convenient to control the remaining amount of snow-melting agent, and there is no need to manually check the material usage in the inner cavity of the storage box 1 frequently.

[0035] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
