Description

Technical Field

[0001] The utility model belongs to the technical field of road rollers, and in particular relates to a watering device applied to a double-steel-wheel road roller. Background Art

[0002] When the double steel wheel roller is working, the steel wheel rolls the paved asphalt mixture to an appropriate compaction degree, so that the asphalt pavement can have a certain load-bearing capacity. However, during the rolling process of the steel wheel and the asphalt mixture, the asphalt mixture will adhere to the steel wheel. Therefore, in order to keep the surface of the steel wheel smooth, a sprinkler system is set up to keep the surface of the steel wheel moist by spraying water on it, thereby preventing the asphalt mixture from adhering to the steel wheel.

[0003] However, after the construction in winter, when the local night temperature is below 0°, if the remaining water in the sprinkler system is not drained, the components in the sprinkler system will easily be frozen (such as the water pump is frozen, the nozzle and the filter are frozen and cracked, etc.), affecting the next use; so after the construction is completed every day, the operator is required to drain all the water in the sprinkler tank, pipes, nozzles and water pumps; but the existing sprinkler system is usually drained manually, and manual drainage usually includes a series of tedious drainage work such as unscrewing the water tank cover, disassembling the pipes, disassembling the nozzles, and draining the water pump; and after the drainage is completed, the operator is required to assemble all the components back, so draining by disassembling the sprinkler system will increase the labor intensity of the operator. Summary of the invention

[0004] The utility model aims to overcome the deficiencies in the prior art and provides a watering device for a double-wheel roller. An antifreeze tank containing antifreeze is provided. When winter construction is completed, the antifreeze purpose is achieved by conveying antifreeze to a water pump and a spraying assembly.

[0005] The utility model provides the following technical solutions:

[0006] A watering device for a double-steel-wheel roller comprises: a watering box, a water outlet pipe being connected to the watering box; an antifreeze tank, antifreeze being contained in the antifreeze tank, a liquid outlet pipe being connected to the antifreeze tank, a three-way electric control valve being installed between an outlet of the liquid outlet pipe and the outlet of the water outlet pipe, and the three-way electric control valve being further connected to a main water pipe; a water pump, a water inlet of the water pump being connected to an end of the main water pipe away from the three-way electric control valve; a spraying assembly, the spraying assembly being connected to the water outlet of the water pump through a pipeline; a speed sensor, the speed sensor being installed on the steel wheel of the double-steel-wheel roller; an engine speed sensor, the engine speed sensor being installed on the engine of the double-steel-wheel roller; and a controller, the controller being electrically connected to the three-way electric control valve, the water pump, the speed sensor and the engine speed sensor.

[0007] Furthermore, a filter is provided on the main water pipe between the three-way electric control valve and the water pump.

[0008] Furthermore, it also includes a display, which is electrically connected to the controller.

[0009] Furthermore, the spray assembly includes a sprinkler head and a sprinkler pipe with both ends blocked, the sprinkler heads are arranged on the sprinkler pipe at intervals, and the multiple sprinkler heads are connected to the inner cavity of the sprinkler pipe.

[0010] Furthermore, the sprinkler head is a sprinkler head with a one-way valve.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. Watering tank and water pump. When the double-wheel roller is in working mode, the water outlet pipe and the main water pipe are connected through a three-way electric control valve. The water pump pumps water and sprays it on the steel wheels of the double-wheel roller through the spraying assembly to achieve normal watering function and prevent asphalt from sticking to the steel wheels.

[0013] 2. After the winter construction is completed, when the local night temperature is below 0°, the liquid outlet pipe and the main water pipe are connected through the three-way electric control valve, the water pump draws antifreeze from the antifreeze tank, and the antifreeze is continuously sprayed for 2 minutes through the spray assembly; on the one hand, this can achieve the purpose of flushing the pipeline, and on the other hand, the three-way electric control valve, water pump and spray assembly can be filled with antifreeze to achieve the antifreeze effect of the sprinkler device. Therefore, when the sprinkler device of the utility model needs to be antifreeze treated, no components need to be disassembled, thereby reducing the labor intensity of the operator.

[0014] 3. By setting a three-way electric control valve, the sprinkler device only needs to set up one water pump to realize the two working modes of supplying antifreeze and supplying water.

[0015] 4. A speed sensor is provided to detect the speed of the double-wheel roller in real time. A speed preset value is provided in the controller. When the detected speed is higher than the speed preset value, the controller controls the water pump to spray water onto the steel wheel.

[0016] 5. By setting up an engine speed sensor, the engine speed sensor is used to detect the engine speed in real time. A speed preset value is set in the controller. When the detected speed is lower than the speed preset value, the controller controls the three-way electric control valve and the water pump to pump antifreeze for 2 minutes so that the sprinkler device can be antifreeze.

[0022] Embodiment 1:

[0023] like Figure 1 and Figure 2 As shown, this embodiment provides a watering device applied to a double-wheel roller, comprising: a watering box 1, to which a water outlet pipe is connected;

[0024] In this embodiment, a water inlet pipe is provided in the sprinkler box 1, and the water inlet pipe can be connected to a water source through a pipeline. A drain pipe is provided on the sprinkler box 1 to drain the water in the sprinkler box 1. When anti-freezing measures are required, the water in the sprinkler box 1 is drained by opening the valve on the drain pipe.

[0025] An antifreeze tank 2, in which antifreeze is contained, the antifreeze tank 2 is connected with a liquid outlet pipe, a three-way electric control valve 3 is installed between the outlet of the liquid outlet pipe and the outlet of the water outlet pipe, and the three-way electric control valve 3 is also connected to the main water pipe;

[0026] In this embodiment, an antifreeze liquid connecting pipe is installed on the antifreeze liquid tank 2, and the antifreeze liquid connecting pipe can be connected with the antifreeze liquid delivery pipe through a pipeline, so as to inject antifreeze liquid into the antifreeze liquid tank.

[0027] A water pump 5, wherein the water inlet of the water pump 5 is connected to an end of the main water pipe away from the three-way electric control valve 3;

[0028] In this embodiment, a regulating valve for adjusting flow is installed in the outlet pipeline of the water pump.

[0029] A spray assembly, the spray assembly is connected to the water outlet of the water pump 5 through a pipeline;

[0030] In this embodiment, the spray assembly includes a sprinkler head 11 and a sprinkler pipe 10 with both ends blocked. The sprinkler heads 11 are arranged on the sprinkler pipe 10 at intervals, and the plurality of sprinkler heads 11 are connected to the inner cavity of the sprinkler pipe 10 .

[0031] In this embodiment, the pipeline connected to the water outlet of the water pump is communicated with the sprinkler pipe 10; the sprinkler head 11 is a sprinkler head with a one-way valve.

[0032] A speed sensor 6 is installed on the steel wheel of the double steel wheel roller;

[0033] In this embodiment, the speed sensor is used to detect the speed of the double steel wheel roller in real time. A plurality of speed preset values ​​are provided in the controller. When the detected speed is between two adjacent speed preset values, the controller controls the opening of the water pump regulating valve, controls the water output of the water pump, and delivers the required amount of water to the spraying assembly under the current working state (when the detection value of the speed sensor is 0, the controller turns off the water pump).

[0034] An engine speed sensor 9, which is mounted on the engine of the double-wheel roller 13;

The controller 7 controls the three-way electric control valve 3 and the water pump 5 to continuously pump the antifreeze for two minutes, and then turns off the water pump 5. This not only serves the purpose of flushing the pipeline, but also allows the three-way electric control valve 3, the water pump 5 and the spraying assembly to have antifreeze, thereby achieving the antifreeze effect of the sprinkler device. Because the sprinkler head 11 is equipped with a one-way valve, when the water pump extracts liquid (water or antifreeze), the pressure of the liquid opens the one-way valve. When the water pump 5 stops extracting liquid, the one-way valve closes. Therefore, some antifreeze will remain in the three-way electric control valve 3, the water pump 5, the sprinkler pipe 10 and the sprinkler head 11, which plays an antifreeze role.

[0036] In this embodiment, a control switch is installed on the wire connecting the water pump and the power supply. When the work starts, the switch is closed, and when the work is finished and no drainage is required, the switch is opened.

[0037] The controller 7 is electrically connected to the three-way electric control valve 3 , the water pump 5 , the speed sensor 6 and the engine speed sensor 9 .

[0040] In this embodiment, there are two sprinkler devices, and mounting frames 12 are provided on both the front and rear sides of the double-wheel roller 13. The sprinkler tank 1, the antifreeze tank 2, the water pump 5 and the sprinkler pipe 10 are all installed on the corresponding mounting frames.

[0041] Embodiment 2:

[0042] This embodiment provides a watering device for a double-wheel roller, which is different from the first embodiment in that it further includes a display 8, which is electrically connected to the controller 7.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
