Description

Technical Field

[0001] This invention relates to the field of snow removal equipment technology, and in particular to an integrated collaborative operation method and control device for snow throwing, snow compaction and transportation. Background Technology

[0002] In snow removal and transportation operations, the existing conventional snow removal mode mostly adopts a decentralized operation, that is, the snow is first collected and thrown by snow throwing equipment, and then directly loaded and transported by transport vehicles.

[0003] However, snow generally has the physical characteristics of low density, high viscosity, and loose texture. Uncompressed snow contains a large number of air pores and has a very large unit volume, resulting in a very low effective loading capacity of transport vehicles in a single operation and a serious underutilization of the vehicle's cargo space. In order to achieve the established removal target, transport vehicles must significantly increase their round-trip frequency, which not only leads to increased energy consumption but also causes a lot of wasted time, seriously reducing overall operational efficiency.

[0004] Meanwhile, existing equipment and processes lack coordinated design for snow throwing, snow compaction, storage and transportation. Each operation is independent and poorly connected, with low levels of automation and integration. Multiple operators are required to manage different equipment, resulting in high labor input and high labor intensity for operators. Overall snow removal and transportation efficiency is difficult to improve, and it cannot meet the needs of large-scale, high-efficiency, and low-cost municipal and engineering snow removal. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated control device for snow throwing, snow compaction, and transportation. This device can solve the problems of small effective loading capacity per transport, high transport frequency, high energy consumption, and high labor costs in existing snow transport operations.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows: This integrated snow throwing, snow grooming, and transportation control device includes an integrated snow throwing and grooming mechanism, a transportation mechanism, a coupler, and a collaborative control unit; the integrated snow throwing and grooming mechanism is connected to the transportation mechanism through the coupler, and the collaborative control unit is electrically connected to both the integrated snow throwing and grooming mechanism and the coupler; the collaborative control unit includes a receiving unit, a central controller, a transmitting unit, and a signal feedback unit, and the output terminal of the receiving unit, the input terminal of the transmitting unit, and the output terminal of the signal feedback unit are all electrically connected to the central controller; The receiving unit is used to receive control commands and transmit them to the central controller; The signal feedback unit is used to collect the action status signal and pressure signal of the integrated snow throwing and snow pressing mechanism and feed them back to the central controller; The central controller outputs action commands to the sending unit based on the control commands transmitted by the receiving unit and the feedback signals fed back by the signal feedback unit. The sending unit outputs control signals to the integrated snow throwing and snow compacting mechanism and the coupler according to the action command, so as to drive the integrated snow throwing and snow compacting mechanism and the coupler to perform corresponding operation actions.

[0007] In the above-mentioned integrated control device for snow throwing, snow compaction, and transportation, a more specific technical solution may be: the integrated snow throwing and snow compaction mechanism includes a snow compaction chamber, a snow throwing hydraulic pump for conveying snow to the snow compaction chamber, a snow compaction hydraulic pump for compressing the snow in the snow compaction chamber, a snow pushing hydraulic pump for pushing the compressed snow out of the snow compaction chamber, and a snow compaction chamber door opening and closing hydraulic cylinder for driving the snow compaction chamber door to open or close; each hydraulic pump and hydraulic cylinder is equipped with an electromagnetic drive component, and the controlled end of each electromagnetic drive component is electrically connected to the command output end of the sending unit.

[0008] In some possible implementations, a pressure sensor is installed on the snow grooming hydraulic pump, and an opening stroke sensor and a closing stroke sensor are respectively installed on the snow grooming chamber door opening and closing hydraulic cylinder; the pressure sensor is used to collect pressure signals, and the opening stroke sensor and closing stroke sensor are used to collect door operation status signals. Each sensor is electrically connected to the signal feedback unit to collect corresponding monitoring signals and transmit them to the signal feedback unit.

[0009] In some possible implementations, the receiving unit is connected to a button unit, which includes a snow-throwing switch button, a snow-grooming on button, and a coupler-connection / disconnection button. The signal output terminal of each button is electrically connected to the signal input terminal of the receiving unit.

[0010] Another objective of this invention is to provide an integrated collaborative operation method for snow throwing, snow compaction, and transportation, so as to realize automatic collaborative control of each operation process, reduce the intensity of manual operation, and improve the overall efficiency of snow removal and transportation.

[0011] This method, applied to the integrated snow throwing, snow grooming, and transportation control device described in any of the preceding claims, includes the following steps: S1. Snow throwing operation: The receiving unit receives the control command to start snow throwing and transmits it to the central controller. The central controller outputs the snow throwing action command to the sending unit. The sending unit outputs a matching control signal to the integrated snow throwing and snow compacting mechanism to drive the integrated snow throwing and snow compacting mechanism to deliver snow to its snow compacting chamber. Snow throwing stops after the snow compacting chamber is full of snow. S2, Snow Grooming Operation: The receiving unit receives the control command to start snow grooming and transmits it to the central controller. The central controller outputs the snow grooming action command to the sending unit. The sending unit outputs a matching control signal to the integrated snow throwing and snow grooming mechanism to drive the integrated snow throwing and snow grooming mechanism to compress the snow in its snow grooming chamber. At the same time, the signal feedback unit collects the pressure signal of the snow grooming operation in real time and sends it back to the central controller. The central controller monitors the pressure signal in real time. S3. Snow Grooming Stop and Door Opening Linkage: When the central controller determines that the pressure signal returned by the signal feedback unit has reached the calibrated value, it outputs a snow grooming stop command to the sending unit. The sending unit outputs a snow grooming stop control signal to the integrated snow throwing and snow grooming mechanism, cutting off the power output for snow grooming operations. After the snow grooming operation stops, the central controller outputs a door opening action command to the sending unit. The sending unit outputs a door opening control signal to the integrated snow throwing and snow grooming mechanism, driving the hydraulic cylinder of the snow grooming chamber of the integrated snow throwing and snow grooming mechanism to open the snow grooming chamber. S4. Snow Pushing Operation: The signal feedback unit collects the real-time action status signal of the snow compactor door of the integrated snow throwing and snow compacting mechanism through the door opening position stroke sensor and sends it back to the central controller. When the central controller determines that the signal has reached the preset calibration position of door opening position, it outputs a snow pushing action command to the sending unit. The sending unit outputs a snow pushing control signal to the integrated snow throwing and snow compacting mechanism, driving it to push the compressed snow out of the snow compactor and push it to the transportation mechanism. S5. Compartment Reset and Cyclic Operation: After snow pushing is completed, the central controller outputs a door-closing command to the sending unit, which in turn outputs a door-closing control signal to the integrated snow throwing and snow pressing mechanism. This drives the hydraulic cylinders of the snow pressing compartment to close, thus shutting down the snow pressing compartment. The signal feedback unit collects the door movement status signal of the integrated snow throwing and snow pressing mechanism through the door-closing stroke sensor and sends it back to the central controller. When the central controller determines that the signal has reached the preset calibration position of door-closing, the integrated snow throwing and snow pressing mechanism completes the operation reset. When the transport mechanism is fully loaded, the receiving unit receives the control command for coupler separation, and the central controller controls the coupler to unlock, separating the transport mechanism from the integrated snow throwing and snow pressing mechanism. After separation, the integrated snow throwing and snow pressing mechanism receives the control command to start snow throwing through the receiving unit, initiating the next round of snow throwing and snow pressing operations.

[0012] In the above-mentioned integrated collaborative operation method for snow throwing, snow compaction, and transportation, a more specific technical solution may be: the central controller pre-stores the snow compaction pressure calibration value and the calibrated position of the silo door opening and closing stroke; the signal feedback unit continuously transmits the pressure signal and silo door action status signal collected in real time back to the central controller; the central controller compares the real-time signal with the corresponding calibration value and determines the result; when the real-time signal reaches the calibration value, it triggers the output of the instruction for the next operation step.

[0013] By adopting the above technical solution, the present invention has the following advantages compared with the prior art: 1. This invention achieves unified control of all actions—snow throwing, snow compaction, snow chamber opening / closing, snow pushing, and coupling / disconnection—through a collaborative control unit that centrally manages the integrated snow throwing and compaction mechanism, coupler, and transport mechanism. The integrated snow throwing and compaction mechanism integrates the snow throwing, snow compaction, and snow pushing components with the snow compaction chamber. It works in conjunction with a hydraulic pump, solenoid valves, and a signal feedback unit with pressure sensors and motion status sensors to achieve synchronized action execution and status monitoring. The coupler and transport mechanism are precisely connected, and the coupler controls the solenoid valves in conjunction with the collaborative control unit to achieve docking and disengagement between the transport mechanism and the snow throwing and compaction mechanism. The collaborative control unit centralizes all operational instructions to the receiving unit, enabling button-based operation for snow throwing, snow compaction, and coupler engagement / disengagement, replacing the multi-terminal control mode of traditional distributed equipment. The signal feedback unit works in conjunction with the central controller to achieve automatic monitoring of operational status and automatic triggering of steps. This eliminates the need for multiple operators to manage different equipment separately; only a small number of personnel are required to perform simple button operations to achieve full-process control, significantly reducing manual labor and lowering the labor intensity and operational threshold. The device has a compact overall structure, occupies little space, and its components work together to ensure that the snow material is conveyed without leakage and that the mechanism moves smoothly without jamming, making it highly practical.

[0014] 2. The method of this invention achieves automatic switching and streamlined coordination of each step—snow throwing, snow compaction, door opening, snow pushing, reset, and cycle—through a coordinated control logic of signal acquisition, feedback judgment, and command output. Once the snow compaction pressure reaches the target, door opening is automatically triggered; once the door is fully open, snow pushing is automatically triggered; and after snow pushing is completed, door closing and reset are automatically triggered. No manual intervention is required for any step, avoiding operational errors and stagnation caused by human error, making the entire process more standardized and precise. Simultaneously, a parallel scheduling logic for snow handling and transportation is adopted. After the transportation mechanism is fully loaded and separated, the snow throwing and compaction mechanism does not need to wait for transportation to complete before directly starting the next round of snow throwing and compaction operations. After the transportation mechanism completes transportation and reconnects, the snow pushing step is directly triggered, quickly pushing the compressed snow to the transportation mechanism, significantly shortening the overall operation time and improving snow removal and transportation efficiency. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the integrated control device for snow throwing, snow pressing, and transportation. Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Figure 1The integrated snow throwing, snow grooming, and transportation control device shown mainly includes an integrated snow throwing and snow grooming mechanism, a transportation mechanism, a coupler, and a collaborative control unit. The integrated snow throwing and snow grooming mechanism is detachably connected to the transportation mechanism through the coupler. The connection point between the two is provided with a connection part that matches the coupler to ensure a firm connection. The collaborative control unit is electrically connected to both the integrated snow throwing and snow grooming mechanism and the coupler.

[0017] The collaborative control unit specifically includes a receiving unit, a central controller, a transmitting unit, and a signal feedback unit. The output of the receiving unit, the input of the transmitting unit, and the output of the signal feedback unit are all electrically connected to the central controller. The receiving unit receives control commands and transmits them to the central controller. The signal feedback unit collects the operational status and pressure signals of the integrated snow-throwing and snow-pressing mechanism and feeds them back to the central controller. Based on the control commands transmitted by the receiving unit and the feedback signals from the signal feedback unit, the central controller outputs operational commands to the transmitting unit. The transmitting unit outputs control signals to the integrated snow-throwing and snow-pressing mechanism and the coupler based on the operational commands, driving each actuator to complete the corresponding operational actions.

[0018] The receiving unit is also connected to an external button unit, which includes a snow-throwing switch button, a snow-pressing on button, and a coupler-connected / separated button. The signal output terminals of each button are electrically connected to the signal input terminals of the receiving unit, realizing centralized button input of control commands and unified input of operation commands, which greatly simplifies the manual operation process.

[0019] The integrated snow-throwing and snow-pressing mechanism comprises a snow-pressing chamber, a snow-throwing hydraulic pump, a snow-pressing hydraulic pump, a snow-pushing hydraulic pump, and a snow-pressing chamber door-opening hydraulic cylinder. The snow-throwing hydraulic pump delivers loose snow into the snow-pressing chamber; the snow-pressing hydraulic pump compacts the snow within the chamber, reducing its volume and increasing its density; the snow-pushing hydraulic pump smoothly pushes the compressed snow out of the chamber; and the snow-pressing chamber door-opening hydraulic cylinder opens or closes the chamber door, coordinating with snow-pushing and resetting operations. The entire mechanism achieves integrated, continuous snow processing from throwing and compressing to pushing, featuring a compact structure and a short snow transport path, effectively reducing snow loss.

[0020] Each hydraulic pump and hydraulic cylinder is equipped with an electromagnetic drive assembly, specifically including solenoid valves for snow-throwing hydraulic pumps, snow-pressing hydraulic pumps, snow-pushing hydraulic pumps, and snow-pressing chamber door opening / closing hydraulic cylinders; couplers are also equipped with coupler solenoid valves. The control terminals of each solenoid valve are electrically connected to the command output terminal of the sending unit, serving as actuating components to achieve precise drive of each mechanism. The solenoid valves offer fast response and high control precision, ensuring accurate and delay-free execution of each mechanism's actions.

[0021] The drive end of the coupler is connected to the output end of the matching electromagnetic drive component. Locking or unlocking the coupler is achieved by switching the electromagnetic drive component on and off. In this embodiment, the coupler connection adopts a passive mechanical structure. The male connector of the coupler at the transport mechanism end docks with the female connector of the coupler at the integrated snow-throwing and snow-pressing mechanism end. It automatically locks when docked, and the connection is achieved by the connecting rod vibrating after docking with the seat, automatically locking without electronic intervention. The coupler separation is achieved by the co-control unit controlling the pneumatic control solenoid valve to open the air path. The solenoid valve opens the air path, and the female connector of the coupler receives air, driving the coupler to separate. The coupler is then unlocked by pneumatic control. In another embodiment, the coupler is an electrically controlled quick connector, where the on / off state of the electromagnetic drive component directly controls the locking or unlocking of the coupler. In yet another embodiment, the coupler is a hydraulic quick connector, where the electromagnetic drive component controls the on / off state of the hydraulic oil circuit, indirectly achieving the locking or unlocking of the coupler. The above-mentioned coupling structures can achieve secure locking and smooth separation, meeting the usage requirements of rapid docking and separation between the transportation mechanism and the integrated snow throwing and snow pressing mechanism, and are suitable for cyclic operation modes.

[0022] The signal feedback unit includes a pressure sensor, a door opening stroke sensor, and a door closing stroke sensor. The pressure sensor is mounted on the snow grooming hydraulic pump to collect pressure signals during snow grooming operations in real time. The door opening and closing stroke sensors are both mounted on the hydraulic cylinders for opening and closing the snow grooming compartment doors, respectively, to collect door opening and closing status signals. The signal output terminals of each sensor are electrically connected to the central controller, synchronously transmitting the real-time collected pressure and status signals back to the central controller, achieving accurate monitoring of the entire operation.

[0023] In this embodiment, all hydraulic pumps, solenoid valves, and sensors adopt conventional hydraulic control and detection components in the field. The appropriate models and specifications can be flexibly selected according to the scale of the actual snow removal operation and site requirements. The circuit connection and hydraulic pipeline connection between the components adopt conventional wiring and layout methods, which are conventional technical means in the field and will not be described in detail here.

[0024] Based on the aforementioned control device, this embodiment provides an integrated collaborative operation method for snow throwing, snow compaction, and transportation. This method achieves coordinated action, signal feedback, and closed-loop control of various mechanisms through a collaborative control unit, thereby completing automated snow removal and transportation operations. The specific steps are as follows: S1, Snow Throwing Operation The operator presses the snow-throwing switch button in the control unit. The receiving unit receives the snow-throwing start control command and transmits it to the central controller in real time. After parsing the command, the central controller outputs a snow-throwing action command to the sending unit. The sending unit outputs a control signal to the solenoid valve of the snow-throwing hydraulic pump, driving the snow-throwing hydraulic pump to start and continuously deliver snow into the snow compactor. Once the snow compactor is full, the operator presses the snow-throwing switch button again to shut off the snow-throwing power, and the snow-throwing operation stops. This command-driven mode ensures precise action execution, and the full-completion stop setting effectively prevents snow overflow, improves operational standardization, and reduces manual monitoring costs.

[0025] S2, Snow grooming operations After the snow grooming chamber is filled with snow, the operator presses the snow grooming start button. The receiving unit receives the snow grooming start command and transmits it to the central controller. The central controller outputs a snow grooming action command to the sending unit, which in turn outputs a control signal to the solenoid valve of the snow grooming hydraulic pump, driving the snow grooming hydraulic pump to start and mechanically compress the loose snow in the snow grooming chamber.

[0026] Throughout the snow grooming operation, the pressure sensor in the signal feedback unit collects the pressure signal from the snow grooming hydraulic pump in real time and continuously transmits the signal back to the central controller, which monitors the pressure signal in real time. Mechanical compression effectively reduces snow volume and increases snow density, laying the foundation for increasing the single-load capacity of the transport vehicle. Simultaneously, real-time pressure monitoring ensures that the snow compression effect meets standards, avoiding the problem of limited transport capacity due to insufficient compression.

[0027] S3, Snow grooming stop and door opening linkage The central controller has pre-stored snow grooming pressure calibration values ​​and continuously compares the real-time pressure signals returned by the pressure sensors with the calibration values. When the real-time pressure signal reaches the preset calibration value, it indicates that the snow has been properly compressed, and the central controller immediately outputs a snow grooming stop command to the transmitting unit, cutting off the snow grooming power and stopping the snow grooming operation.

[0028] After snow compaction stops, the central controller synchronously sends an opening command to the sending unit. The sending unit then sends a control signal to the solenoid valve of the hydraulic cylinder that powers the snow compactor door, driving the cylinder to open smoothly. This automatic linkage operation after the pressure reaches the target level allows for seamless switching between work steps, eliminating the need for manual intervention to determine the completion point of snow compaction. This significantly improves the level of automation and ensures timely and smooth workflow.

[0029] S4, Snow removal operation During the opening process of the snowpack door, the door opening position travel sensor of the signal feedback unit collects the door's action status signal in real time and continuously transmits it back to the central controller. The central controller compares the real-time collected action status signal with the pre-stored door opening position calibration. When it determines that the door is fully open and has reached the preset calibration position, it immediately outputs a snow pushing command to the sending unit, driving the snow pushing hydraulic pump to start, smoothly pushing out the compressed snow in the snow compactor and accurately sending it into the snow collection box of the transport mechanism.

[0030] Once the door is fully open, the snow-pushing mechanism automatically triggers, effectively preventing snow-pushing jams and leaks caused by the door not being fully open. This ensures smooth snow-pushing operations, complete snow delivery, and no spillage or residue.

[0031] S5. Warehouse Reset and Cyclic Operation After snow removal is completed, the central controller sends a closing command to the transmitting unit, driving the hydraulic cylinders of the snow groomer to reverse and close the snow groomer door. The door closing position travel sensor collects the door's movement status signal in real time and sends it back to the central controller; when the signal reaches the door closing position calibration position, the integrated snow throwing and grooming mechanism completes a full reset and is ready to enter the next work cycle, ensuring continuous operation.

[0032] Once the snow collection box of the transport vehicle is full of snow, the operator presses the coupler engagement / disengagement button. The central controller then activates the solenoid valve associated with the coupler, unlocking it and allowing the transport vehicle to quickly separate from the integrated snow throwing and compaction mechanism. After separation, the transport vehicle can independently proceed to the unloading location to complete the transfer operation. During this time, without waiting for the transport vehicle to return, the operator can directly activate the snow throwing switch, allowing the integrated snow throwing and compaction mechanism to independently carry out the next round of snow throwing and compaction operations, enabling parallel snow handling and transfer operations.

[0033] Once the transport unit returns after completing its transfer, it is reconnected and locked to the integrated snow-throwing and snow-pressing mechanism via a coupler. The central controller can then directly trigger the snow-push command, quickly pushing the compressed snow into the transport unit. This eliminates the inefficient traditional model of "transfer waiting for processing, processing waiting for transfer," significantly shortening the overall operation time and greatly improving snow removal and transfer efficiency.

[0034] Throughout the entire operation process, the central controller relies on preset calibration values ​​and real-time signal comparison to achieve fully automatic triggering of each step. Only 1 to 2 operators are needed to complete simple button operations to control the entire process, greatly reducing manual input and lowering labor intensity and operating threshold.
