Description

Technical Field

[0001] The utility model relates to the technical field of asphalt compaction operations, in particular to a dual-path watering system for a dual-steel wheel roller. Background Art

[0002] During asphalt compaction, steel-drum rollers need to evenly spray water onto the surface of the steel drum. Due to varying construction speeds, the watering mechanism requires variable adjustment. Without the watering mechanism, the dual steel drums will not function. During watering, the terminal nozzles can easily clog, causing excessive pressure and damage to the water pump. Tandem steel-drum rollers are primarily used for asphalt compaction. Spraying water onto the drums is the best way to prevent adhesion between the steel drums and the asphalt, ensuring proper compaction. During compaction, watering must be adjusted based on the speed to prevent excessive or insufficient water flow. The watering pump transfers water from the water tank through a tee to the front and rear sprinkler pipes, corresponding to the front and rear steel drums.

[0003] Most of the sprinkler systems on the market are supplied by one sprinkler pump, and there is no backup water line. If the water pump is damaged, the double-wheel roller will not work. The adjustment of the watering amount requires a controller, which is relatively expensive. When the double-wheel roller is watering, due to the relatively harsh working environment, the sprinkler terminal and the nozzle are often blocked. According to the linear principle of water volume and pressure of the water pump, the blockage causes the watering amount to decrease and the system pressure to increase, which can easily cause damage to the water pump and other hardware, thereby causing the sprinkler system to fail and the double-wheel roller to be unable to work.

[0004] Therefore, we propose a dual-channel watering system for double-wheel rollers. Utility Model Content

[0005] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a dual-path watering system for a double-steel-wheel roller.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a dual-path sprinkler system for a double-steel-wheel roller, comprising a water filter, a first water pump, a second water pump, a three-way joint, a safety valve, a switching switch, a front sprinkler, a rear sprinkler, a display, a sprinkler adjustment switch, a sprinkler tank, a three-way joint and a bypass; the sprinkler tank is connected to the water filter through a water pipe, the water filter is respectively connected to the first water pump and the second water pump through a water pipe, the first water pump and the second water pump are respectively connected to the three-way joint through a water pipe, and the three-way joint is connected to the safety valve through a water pipe.

[0007] Preferably, the safety valve is used to protect the entire sprinkler system. When the pressure of the sprinkler system is too high and exceeds the pressure of the safety valve, the water flows back to the sprinkler tank through the bypass.

[0008] Preferably, the display integrates display and control, and has a built-in control program for controlling the water pump to achieve multi-level adjustment of watering.

[0009] Preferably, the watering adjustment switch signal acts on a display to select a watering gear.

[0010] Preferably, the switching switch can switch between two watering routes, and the switching is performed by controlling the switch to select the first water pump or the second water pump to operate.

[0011] Preferably, the safety valve is connected to the front sprinkler and the rear sprinkler through water pipes respectively.

[0012] Preferably, the front water sprinkler and the rear water sprinkler are respectively connected to a safety valve.

[0013] Preferably, the safety valve is pressure-sensitive. When the system is blocked, the pressure of the sprinkler system rises and exceeds the set pressure of the safety valve, and the water is bypassed back to the sprinkler tank.

[0014] Preferably, the safety valve is connected to the bypass through a water pipe.

[0015] Preferably, the bypass is connected to the sprinkler box through a water pipe.

[0016] Preferably, the first water pump and the second water pump are respectively connected to the switch via electrical signals.

[0017] Preferably, the switch is connected to the display via an electrical signal.

[0018] Preferably, the display is connected to the sprinkler adjustment switch via an electrical signal.

[0019] Preferably, the sprinkler regulating switch and the switching switch are respectively connected to the first water pump and the second water pump via electrical signals. Beneficial effects

[0020] The utility model provides a dual-channel watering system for a double-steel-wheel roller, which has the following beneficial effects:

[0021] 1. This dual-path sprinkler system for a double-steel-wheel roller integrates a water filter, a first water pump, a second water pump, a three-way joint, a safety valve, a switching switch, a front sprinkler, a rear sprinkler, a display, a sprinkler adjustment switch, a sprinkler tank, a three-way joint, and a bypass, thereby achieving dual protection and flexible control of the sprinkler system. When one water pump fails, the other water pump can continue to work, ensuring the normal operation of the roller and avoiding downtime losses caused by sprinkler system failures. This not only improves the working efficiency and reliability of the double-steel-wheel roller, but also reduces maintenance costs and operational complexity, with significant economic and social benefits.

[0022] 2. This dual-path sprinkler system for double-wheel rollers can automatically adjust the pressure through the design of the safety valve. If the system or the sprinkler terminal is blocked and the pressure exceeds the set pressure of the safety valve, the water will bypass back to the sprinkler tank and the sprinkler will no longer sprinkle water. This protects the sprinkler system and prevents excessive pressure caused by blockage or abnormal conditions, thereby protecting the water pump and other components from damage and extending the service life of the equipment.

[0023] 3. This dual-path watering system for a double-wheel roller is equipped with a display, a watering adjustment switch, and a toggle switch. The integration of the display and the watering adjustment switch allows the operator to easily adjust the watering gear according to actual needs. The display is used for display and multi-speed watering control, replacing the function of the controller, thereby improving the flexibility and efficiency of the operation. There is no need for an additional controller, which is conducive to cost control. The design of the toggle switch allows the operator to quickly switch between front watering and rear watering to adapt to different construction needs, thereby improving the adaptability and flexibility of the operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 This is a system module diagram of the present utility model. DETAILED DESCRIPTION

[0025] Example 1: A dual-path watering system for a double-wheel roller, such as Figure 1 As shown, it includes a water filter, a first water pump, a second water pump, a three-way joint, a safety valve, a switch, a front sprinkler, a rear sprinkler, a display, a sprinkler adjustment switch, a sprinkler tank, a three-way joint and a bypass. The sprinkler tank is connected to the water filter through a water pipe, and the water filter is connected to the first water pump and the second water pump through a water pipe respectively. The safety valve is used to protect the entire sprinkler system. When the pressure of the sprinkler system is too high and exceeds the pressure of the safety valve, the water flow returns to the sprinkler tank through the bypass. The display integrates display and control, and has a built-in control program for controlling the water pump to achieve multi-speed adjustment of sprinkler. The sprinkler adjustment switch signal acts on the display to select the sprinkler gear. The switch can switch between two sprinkler routes. The first water pump or the second water pump can be switched by the control switch. The water pump is working and the safety valve is pressure-sensitive. When the system is blocked, the pressure of the sprinkler system increases and exceeds the set pressure of the safety valve, the system will bypass and return to the sprinkler tank. By integrating the water filter, the first water pump, the second water pump, the three-way joint, the safety valve, the switch, the front sprinkler, the rear sprinkler, the display, the sprinkler adjustment switch, the sprinkler tank, the three-way joint and the bypass, the double protection and flexible control of the sprinkler system are achieved. When one water pump fails, the other water pump can continue to work, ensuring the normal operation of the roller and avoiding the downtime loss caused by the failure of the sprinkler system. It not only improves the working efficiency and reliability of the double steel wheel roller, but also reduces the maintenance cost and operation complexity, with significant economic and social benefits.

[0026] Example 2: Based on Example 1, Figure 1 As shown, the first water pump and the second water pump are respectively connected to the tee through a water pipe, the tee is connected to the safety valve through a water pipe, the safety valve is respectively connected to the front sprinkler and the rear sprinkler through a water pipe, the front sprinkler and the rear sprinkler are respectively connected to the safety valve, and the safety valve is connected to the bypass through a water pipe. Through the design of the safety valve, the system can automatically adjust the pressure. If the system or the sprinkler terminal is blocked and the set pressure of the safety valve is exceeded, the water bypass returns to the sprinkler tank, and the sprinkler head no longer sprinkles water, which protects the sprinkler system and prevents excessive pressure caused by blockage or abnormal conditions, thereby protecting the water pump and other components from damage and extending the service life of the equipment.

[0027] Example 3: Based on Example 1 and Example 2, Figure 1 As shown, the bypass is connected to the sprinkler tank through a water pipe, the first water pump and the second water pump are respectively connected to the switching switch through electrical signals, the switching switch is connected to the display through electrical signals, the display is connected to the sprinkler adjustment switch through electrical signals, the sprinkler adjustment switch and the switching switch are respectively connected to the first water pump and the second water pump through electrical signals. By setting up a display, a sprinkler adjustment switch and a switching switch, the integration of the display and the sprinkler adjustment switch allows the operator to easily adjust the sprinkler gear according to actual needs. The display is used for display and multi-gear sprinkler control, replacing the function of the controller, thereby improving the flexibility and efficiency of the operation, without the need for an additional controller, which is conducive to cost control. The design of the switching switch allows the operator to quickly switch between front sprinkler or rear sprinkler to adapt to different construction needs, thereby improving the adaptability and flexibility of the operation.

[0028] The working principle of the utility model is: during the asphalt compaction work, the first water pump drives the water system to work and perform water sprinkling. If there is a problem with the first water pump, the switch in the cab can be switched to the second water pump to work, and the sprinkler system works normally. The display can make the signal automatic or manual sprinkler mode. The sprinkler terminal sprinkler pipe is corroded or the nozzle is blocked. The smaller the flow, the higher the pressure. When the blockage is large, it is easy to damage the water pump. A safety valve is added to the water circuit. The terminal blockage causes the system pressure to rise. When it exceeds the safety valve limit, the safety valve will bypass the water tank, which plays a good protective role for the water pump. The watering gear position of the water pump is adjusted by the display in the sprinkler system without the need for an additional controller. In the dual-channel sprinkler system, the display The device receives the sprinkler gear switch signal, sets the sprinkler gear, and the switch is in the series circuit. The switch is a three-point type, manually operated, and the middle position is non-working. The upper point and the lower point correspond to the operation of the first water pump and the second water pump respectively. The front end shares a water filter. When the sprinkler system is working, a safety valve is connected in series in the water circuit to set the safety pressure value. When the terminal is not blocked, the safety valve does not work. When the terminal is blocked, the water volume decreases and the pressure increases. After exceeding the system pressure, the safety valve bypasses the water back to the water tank and switches through the switch. The sprinkler gear needs to be set before work or it can be set during work. The switch opens the working water circuit and sprays the water in the water tank onto the surface of the steel wheel. The safety valve only plays a protective role. Only when the terminal is blocked will the water flow bypass.
