Description

Technical Field

[0001] The present disclosure relates to the technical field of road sweeping, and in particular to a spreading system and a spreading machine. Background Art

[0002] Road cleaning may include snow removal, garbage disposal, etc. For example, artificial snow removal, snow melting and snow removal, and mechanical snow removal may be performed. Snow melting and snow removal is performed by spreading a snow melting agent, which may include a solid snow melting agent and a liquid snow melting agent.

[0003] Conventional spreading systems usually spread solid deicing agents. However, since the solute components of liquid deicing agents are the same as those of solid deicing agents, when the solute mass of the liquid deicing agent is equal to the mass of the solid deicing agent, the volume of the liquid deicing agent is greater than that of the solid deicing agent. For a specific area to be cleared, the required volume of solid deicing agent is the same as the required volume of liquid deicing agent; in this case, when the solute mass of the liquid deicing agent used is equal to the mass of the solid deicing agent used, the use of liquid deicing agent can bring a larger snow removal area or a longer snow removal distance compared to the use of solid deicing agent; when the same area to be cleared is treated, the solute mass consumption of the liquid deicing agent is less than the mass consumption of the solid deicing agent, so the use of liquid deicing agent can save snow removal costs. When a spreading system is used to spread liquid deicing agents, the outflow of the liquid deicing agent from the nozzle cannot be adjusted, resulting in poor adjustability and environmental adaptability of the spreading system. Summary of the invention

DETAILED DESCRIPTION

[0016] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0017] In the present disclosure, the terms "first", "second", etc. are used to distinguish one element from another element, and do not have order and importance. In the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limiting the present disclosure.

[0018] In the related art, as mentioned above, compared with solid deicing agents, the use of liquid deicing agents can reduce snow removal costs. In addition, conventional spreading systems use hydraulics to drive liquid delivery pumps, requiring the installation of hydraulic oil transmission pipelines, which increases system complexity and brings difficulties to installation and maintenance.

[0019] In order to at least solve some of the defects described above, the present disclosure provides a spreading system and a spreading machine. In order to facilitate understanding of the present application, the embodiments of the present application are described below in conjunction with the accompanying drawings.

[0020] See also Figure 1The embodiment of the present application provides a spreading system, which includes: a liquid storage tank 100, used to store liquid deicing agent; a liquid delivery pump 200, connected to the liquid storage tank 100; a regulating valve 300, connected to the liquid delivery pump 200; a motor 400, connected to the liquid delivery pump 200, used to provide power for the liquid delivery pump 200 to pump the liquid deicing agent from the liquid storage tank 100 into the regulating valve 300; a nozzle, connected to the regulating valve 300 through an electromagnetic valve, used to spray the liquid deicing agent, the electromagnetic valve is used to realize the connection and disconnection of the deicing agent delivery pipeline between the regulating valve 300 and the nozzle, and the regulating valve 300 is used to adjust the flow rate of the liquid deicing agent flowing to the nozzle.

[0021] It should be noted that the spreading system of the present application can spread liquid snow-melting agent, which can reduce snow removal costs compared to a spreading system that spreads solid snow-melting agent.

[0022] It should be further explained that the regulating valve 300 can be implemented by a known flow valve. Since the regulating valve 300 can adjust the flow of the liquid deicing agent flowing to the nozzle, the flow of the liquid deicing agent sprayed from the nozzle can be adjusted, and accordingly, the flow control can be performed as needed. For example, the spreading system can be set on a spreader or a vehicle, and the spreader or the vehicle can move, and the flow of the liquid deicing agent sprayed from the nozzle can be adjusted according to the moving speed. In this case, precise spreading can be achieved, for example, the flow of the liquid deicing agent can be adjusted according to the vehicle speed. Since the flow of the liquid deicing agent is adjustable, the spreading system has relatively high adjustability; since the flow of the liquid deicing agent can be adjusted according to environmental needs, the environmental adaptability is improved, and accordingly, the waste of the liquid deicing agent is reduced, and the continuous spreading time and spreading distance can be increased.

[0023] Furthermore, the motor 400 is a new energy motor, and the spreading system also includes: a driver 500 connected to the motor 400 and used to drive the motor 400; a new energy battery 600 connected to the driver 500 and used to supply power to the driver 500.

[0024] It should be noted that the present application utilizes an electric motor 400 to provide power for the liquid delivery pump 200; compared with a spreading system that utilizes hydraulic power, it can reduce the setting of hydraulic oil transmission pipelines, etc., improve space utilization, reduce system complexity, and reduce installation and maintenance costs.

[0025] Furthermore, the nozzles include: a first left nozzle NL1, a second left nozzle NL2, a third left nozzle NL3, a first middle nozzle NM1, a second middle nozzle NM2, a third middle nozzle NM3, a first right nozzle NR1, a second right nozzle NR2 and a third right nozzle NR3; the solenoid valves include: a first left nozzle solenoid valve L1, a second left nozzle solenoid valve L2, a third left nozzle solenoid valve L3, a first middle nozzle solenoid valve M1, a second middle nozzle solenoid valve M2, a third middle nozzle solenoid valve M3, a first right nozzle solenoid valve R1, a second right nozzle solenoid valve R2 and a third right nozzle solenoid valve R3; the regulating valve, the first left nozzle solenoid valve L1 and the first left nozzle NL1 are connected in sequence to regulate the The valve, the second left nozzle solenoid valve L2 and the second left nozzle NL2 are connected in sequence, the regulating valve, the third left nozzle solenoid valve L3 and the third left nozzle NL3 are connected in sequence, the regulating valve, the first middle nozzle solenoid valve M1 and the first middle nozzle NM1 are connected in sequence, the regulating valve, the second middle nozzle solenoid valve M2 and the second middle nozzle NM2 are connected in sequence, the regulating valve, the third middle nozzle solenoid valve M3 and the third middle nozzle NM3 are connected in sequence, the regulating valve, the first right nozzle solenoid valve R1 and the first right nozzle NR1 are connected in sequence, the regulating valve, the second right nozzle solenoid valve R2 and the second right nozzle NR2 are connected in sequence, the regulating valve, the third right nozzle solenoid valve R3 and the third right nozzle NR3 are connected in sequence.

[0026] It should be noted that the regulating valve in the exemplary embodiment may include a control end and a liquid transmission end, and the solenoid valve may also include a control end and a liquid transmission end. For example, when the current delivered to the control end of the regulating valve changes, the flow rate of the liquid flowing through the liquid transmission end of the regulating valve will change; when the current delivered to the control end of the solenoid valve is a high-level current or a low-level current, the liquid transmission end of the solenoid valve may be connected or disconnected. Based on this, a controller 700 may be provided as described below, and the controller 700 may be implemented as an intelligent controller; the controller 700 may control the connection or disconnection of the liquid transmission end of the solenoid valve, and control the flow rate of the liquid transmission end of the regulating valve 300. As an alternative, an adjusting knob and a button may also be provided, and the adjusting knob may be connected to the control end of the regulating valve, and the button may be connected to the control end of the solenoid valve. The adjusting knob and the button here may be implemented by a sliding rheostat, and the sliding rheostat may be connected to a power supply. Here, the liquid transmission end may be used for the transmission of a liquid snow melting agent, for example, the liquid transmission end of the regulating valve 300, the liquid transmission end of the solenoid valve, and the nozzle are connected in sequence.

[0027] Furthermore, the spreading system also includes a controller 700, and the controller 700 is connected to the driver 500, the regulating valve 300 and the solenoid valve respectively.

[0028] It should be noted that the driver 500 can also receive high-level current and low-level current. For example, it turns on when receiving a high-level current to start working; it turns off when not receiving a high-level current or receiving a low-level current to stop working; the controller 700 can also control the speed of the motor 400 by controlling the driver 500, thereby adjusting the flow rate of the liquid delivery pump 200.

[0029] It should be further explained that the controller 700 can be connected to the control end of the regulating valve 300; the controller 700 can also be connected to the control end of each solenoid valve to realize flow adjustment operation, spreading start operation and spreading stop operation. Since the flow, spreading start and spreading stop are controllable, the waste of liquid snow melting agent can be reduced. In addition, each solenoid valve can be equipped with a corresponding switch button, which is connected to the control end of the solenoid valve. Through the controller 700 or the switch button, the spraying start control and spraying stop control of each nozzle can be realized, which improves convenience and flexibility.

[0030] Furthermore, the spreading system also includes: a liquid return valve 800, which is connected to the liquid storage tank 100, the liquid delivery pump 200 and the regulating valve 300 respectively.

[0031] It should be noted that the liquid return valve 800 can also be implemented as a pressure relief valve. The liquid return valve 800 can reduce the internal pressure of the transmission pipeline and increase the service life of the system.

[0032] Furthermore, the spreading system also includes: a flow meter 900, which is connected to the liquid return valve 800, the controller 700, the liquid delivery pump 200 and the regulating valve 300 respectively.

[0033] It should be noted that the flow meter 900 can perform flow statistics, and the statistical flow can be directly transmitted to the display, or transmitted to the display through the controller 700, so as to display the flow and provide a reference for flow regulation.

[0034] Based on the above, the present disclosure further provides a spreader, including the spreading system in the above embodiments. The spreader or spreading system in the embodiments can be installed on a vehicle, where the vehicle is an engineering vehicle, an agricultural vehicle, a road cleaning vehicle, etc.
