Description

Technical Field

[0001] This invention belongs to the field of road construction equipment technology, specifically relating to a curbstone watering and mulching device and construction method. Background Technology

[0002] During municipal road construction, the curb stones need to be covered with a protective film before asphalt mixture paving or concrete base pouring for sidewalks. This film ensures that the curb stones are not contaminated by the high-temperature asphalt mixture or cast-in-place concrete, thus protecting the finished curb stones. If the curb stones are not covered with a protective film, it will be very difficult to clean the asphalt or concrete from the curb stones after the asphalt paving or cast-in-place concrete is completed. Larger coarse aggregates in the concrete or asphalt can be removed, but asphalt oil can only be ground off. This has a huge impact on the finished appearance of the curb stones, greatly reducing their aesthetics and practicality.

[0003] The existing process for applying protective film to curbstones generally involves first sprinkling water on the curbstone surface, then covering it with a protective film, and finally compacting the film. This entire process is done manually, which is time-consuming and labor-intensive. The protective film does not adhere tightly to the curbstone, and it is easily separated from the curbstone by external factors such as strong winds, resulting in poor coverage. Furthermore, workers arbitrarily control the amount of water sprayed during the application of the protective film, requiring frequent stops to add water, significantly extending the construction period. Uneven watering also leads to substantial water waste. The frequent adjustments to the protective film during application further increase construction time and significantly delay the project's progress. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a curbstone watering and mulching device and its construction method.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a curbstone watering and mulching device, comprising a frame mechanism and a mist spraying mechanism. The frame mechanism includes a frame body, wheels, and handles. The mist spraying mechanism includes a water tank, a water outlet pipe, and spray nozzles. The two ends of the water outlet pipe are detachably connected to the water tank and the spray nozzles, respectively. The curbstone watering and mulching device also includes a protective film raw material sleeve, a traction mechanism, a pressing mechanism, a side pressing mechanism, and a protective film roll. The protective film roll includes a film roll base and a protective film extension portion.

The upper surface of the curbstone is attached to the protruding part of the protective film through the pressing mechanism, and the side of the curbstone is attached to the protruding part of the protective film through the side pressing mechanism.

[0008] Preferably, the pressing mechanism includes a pressing arm, a pressing assist spring, and a pressing roller brush. The two ends of the pressing arm are detachably connected to the pressing assist spring and the pressing roller brush, respectively. The pressing assist spring has a vertical direction of elastic extension and contraction. The end of the pressing assist spring away from the pressing arm is installed on the vehicle frame body. The side of the pressing roller brush is in contact with the protective film protrusion on the upper side of the curb.

[0009] The side pressure mechanism includes a side pressure arm, a side pressure assist spring, and a side pressure roller brush. The two ends of the side pressure arm are detachably connected to the side pressure assist spring and the side pressure roller brush, respectively. The side pressure assist spring has a horizontal elastic extension direction. The end of the side pressure assist spring away from the side pressure arm is installed on the vehicle frame body. The side of the side pressure roller brush is in contact with the protective film protrusion on the side of the curb.

[0010] Preferably, the downward pressure roller brush is cylindrical with a horizontal axis and rotates around its own axis, and the side pressure roller brush is cylindrical with a vertical axis and rotates around its own axis.

[0011] Preferably, the wheel is an anti-slip one-way wheel, the frame mechanism includes a telescopic sleeve, the anti-slip one-way wheel is detachably connected to the bottom surface of the frame body through the telescopic sleeve, and the movement direction of the anti-slip one-way wheel is parallel to the length direction of the curb.

[0012] Preferably, the bending roller is cylindrical, rotates around its own axis, and the upper end of the bending roller is inclined towards the end closer to the curb.

[0013] Preferably, the bending roller includes a connecting part, a bending part, and a telescopic rod. The connecting part and the bending part are both cylindrical and rotate around their own axis. The connecting part and the bending part are hinged together, and the two ends of the telescopic rod are detachably connected to the connecting part and the bending part, respectively.

[0014] Preferably, the curbstone watering and film covering device further includes a controller and a speed sensor, and the mist spraying mechanism further includes a throttle valve, which is installed on the water outlet pipe;

[0015] The controller is communicatively connected to the speed sensor and the throttle valve. The controller is mounted on the main body of the vehicle frame, and the speed sensor is mounted on the bottom of the main body of the vehicle frame.

[0016] Preferably, the downward pressing mechanism includes a blower one, and the side pressing mechanism includes a blower two. Both the blower one and the blower two are mounted on the vehicle frame body. The blower one blows air vertically downward, and the blower two blows air horizontally.

[0017] Preferably, the curbstone sprinkling and mulching device also includes a suction fan, which is installed at the front end of the vehicle frame.

[0018] A method for constructing a curbstone water spraying and mulching system, comprising the following steps:

[0019] Step 1: Fill the water tank;

[0020] Step 2: Install the protective film roll onto the protective film raw material sleeve;

[0021] Step 3: Secure the starting end of the protective film roll;

[0022] Step 4: Turn on the sprinkler system

[0023] Step 5: Lay out the protective film at the protruding part;

[0024] Step Six: Push the curbstone water spraying and mulching device to the endpoint;

[0025] Step 7: Turn off the mist spraying mechanism to end the construction.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0027] (1) This device is more convenient and faster than manual construction of road curb watering and mulching. Only one person is needed to push the handle to carry out the construction, which saves labor costs. The mist spraying mechanism sprays in the form of mist, which greatly saves water consumption. The laying and compaction of the protective film extension are carried out at the same time, and the laying and compaction effect is good.

[0028] (2) The bending roller bends the protective film protrusion. By bending the same protective film protrusion, the bent protective film protrusion is attached to the top surface and side surface of the curbstone respectively. Therefore, there will be no seam at the corner of the covered curbstone. The film is firm and the film effect is better. Asphalt or concrete will not enter the film along the seam and thus contaminate the surface of the curbstone. The same protective film reduces the width of the protective film protrusion. The protective film covering the curbstone is a whole and will not be separated from the curbstone due to external factors such as strong wind.

[0029] (3) The downward pressure assist spring ensures that the downward pressure roller brush and the protective film protrusion on the upper side of the curbstone are closely attached, and the compaction effect is good. The side pressure assist spring ensures that the side pressure roller brush and the protective film protrusion on the side of the curbstone are closely attached, and the compaction effect is good. The curbstone and the protective film will not be separated due to external factors such as strong wind.

[0030] (4) The bending roller includes a connecting part, a bending part and a telescopic rod. The angle between the connecting part and the bending part can be adjusted by the extension and retraction of the telescopic rod. The most suitable angle can be adjusted according to the actual working conditions of the construction site and the actual size of the curb.

[0031] (5) The curbstone water spraying and film covering device also includes a controller and a speed sensor. The speed sensor detects the wheel speed in real time. When the wheel speed is low, the speed sensor sends a signal to the controller. The controller reduces the amount of water sprayed through the throttle valve, which saves water resources, ensures the uniformity of water spraying, and has a better film covering effect. If the water in the tank decreases after a long period of spraying, and the same thrust is still used to push the tank, the wheel speed will be higher. The speed sensor sends a signal to the controller. The controller increases the amount of water sprayed through the throttle valve, which ensures the uniformity of water spraying and has a good film covering effect.

[0032] (6) The air blower one blows vertically downwards, and the air blower two blows horizontally. Using the air blower one and the air blower two to compact the film results in a larger contact area and a better compaction effect on the edge of the protective film protrusion. Since the air blower one and the air blower two do not directly contact the protective film protrusion, they will not scratch the protective film and the frictional resistance is small, making it easier for the operator to push the handle.

[0049] To better understand the above-mentioned objectives, features and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0050] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0051] Example 1

The side of the side pressure roller brush 63 is attached to the protective film protrusion 72 on the side of the curb stone 8.

[0057] like Figure 1 and Figure 3 As shown, the downward pressure roller brush 53 is cylindrical with a horizontal axis and rotates around its own axis. The side pressure roller brush 63 is cylindrical with a vertical axis and rotates around its own axis.

[0058] like Figure 3 As shown, wheel 12 is a non-slip one-way wheel, and the frame mechanism 1 includes a telescopic sleeve. The non-slip one-way wheel is detachably connected to the bottom surface of the frame body 11 through the telescopic sleeve. The movement direction of the non-slip one-way wheel is parallel to the length direction of the curb stone 8.

[0059] like Figure 1 and Figure 4 As shown, the bending roller 22 is cylindrical and rotates around its own axis. The upper end of the bending roller 22 is inclined towards the end closer to the curb stone 8.

[0060] The curbstone water spraying and mulching device also includes a controller and a speed sensor. The speed sensor detects the rotational speed of the wheel 12. The mist spraying mechanism 3 also includes a throttle valve, which is installed on the water outlet pipe 32.

[0061] The controller is connected to the speed sensor and the throttle valve. The controller is installed on the frame body 11, and the speed sensor is installed at the bottom of the frame body 11.

[0062] The speed sensor is a Hall effect speed sensor, which includes a magnet and a Hall element. The magnet is mounted on the wheel 12 and rotates with the rotation of the wheel 12. The Hall element is mounted at the bottom of the frame body 11 near the wheel 12. The specific model of the Hall effect speed sensor is M18 Hall effect speed sensor.

[0063] The mist spraying mechanism 3 also includes a water pump, which provides power to transport water from the water tank 31 through the water outlet pipe 32 to the spray nozzle. The spray nozzle atomizes the water and sprays it out. The spraying direction of the spray nozzle is towards the edge shared by the top and side surfaces of the curbstone 8.

[0064] Example 2

[0065] The difference between this embodiment and Embodiment 1 is:

[0066] The bending roller 22 includes a connecting part, a bending part, and a telescopic rod. Both the connecting part and the bending part are cylindrical and rotate around their own axis. The connecting part and the bending part are hinged together, and the two ends of the telescopic rod are detachably connected to the connecting part and the bending part, respectively.

[0067] The telescopic rod allows for adjustment of the angle formed by the axis of the connecting part and the axis of the bending part. Based on the actual size of the curbstone 8 and the road conditions, the most suitable angle can be adjusted to enhance the bending effect.

[0068] Example 3

[0069] The difference between this embodiment and Embodiment 1 is:

[0076] Step 4: Turn on the sprinkler system. Water is transported from the water tank 31 to the sprinkler head through the water outlet pipe 32. The sprinkler head atomizes the water and sprays it out to wet the surface of the uncoated curbstone 8.

[0077] Step 5: Lay the protective film extension 72. By pushing the handle 13, the curbstone water spraying and film covering device moves along the length of the curbstone 8.
