Description

Technical Field

[0001] This utility model relates to the field of snowplow technology, specifically a self-powered snowplow. Background Technology

[0002] Self-powered snow blowers are indispensable winter snow removal and emergency equipment on the market today. They are suitable for snow blowing operations on highways, airports, and roads, as well as for loading snow onto trucks on urban roads. With their fast operating speed, they are ideal snow removal machinery, meeting the requirements for rapid snow removal in cities.

[0003] In existing products, the self-powered snow blower's entire transmission system lacks a controllable protection system, relying solely on mechanical protection. This can damage the coupling and chain drive during use, rendering the snow blower unusable and causing complicated repairs. Furthermore, the transmission box uses roller chains and oil bath lubrication, which can overheat during operation, damaging the chain and affecting the entire transmission system. Regarding the engine, this snow blower has high power and generates significant vibration, resulting in poor vibration damping of the engine radiator, easily damaging the fan blades and causing poor performance. The blower-style cooling method allows foreign objects to impact the radiator's exterior, damaging it and requiring frequent replacement of the engine cover filter, increasing maintenance costs and user difficulty. As for the frame, the original frame was essentially level with the ground during use, causing snow to accumulate inside the equipment. Many of the openwork designs were ineffective, making cleaning and maintenance inconvenient and causing severe damage to many electrical components. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a self-powered snowplow that solves the problems of protection of the entire transmission system, overheating of the transmission box, lubrication, poor noise reduction, and different vibration frequencies of the engine and radiator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A self-powered snowplow includes an engine, transmission box, hydraulic clutch, hydraulic oil pump, snowplow auger, and snow-rolling impeller mounted on an outer frame. The engine and hydraulic clutch are connected by a transmission. The snowplow also includes:

[0008] The telescopic long coupling is connected to the transmission box at one end and to the snow removal auger and snow rolling impeller at the other end.

[0009] The torque sensor is connected to the telescopic long coupling at one end and to the transmission box at the other end.

[0010] The control box is equipped with a power switch, which is connected to the hydraulic clutch; the torque sensor and the power switch are electrically connected to the control box.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] like Figures 1 to 8 As shown, a self-powered snowplow includes an engine 6, a transmission box 3, a hydraulic clutch 5, a hydraulic oil pump 9, a snowplow auger, and a snow-rolling impeller mounted on an outer frame 21. The snowplow auger and snow-rolling impeller serve as snow removal devices. The engine 6 and the hydraulic clutch 5 are connected by a transmission. The snowplow also includes:

[0032] The telescopic short coupling 4 is connected to the hydraulic clutch 5 at one end and to the transmission box 3 at the other end.

[0033] The telescopic long coupling 1 is connected to the transmission box 3 at one end and to the snow removal auger and snow rolling impeller via a commutator at the other end.

[0034] Torque sensor 2 is connected to telescopic long coupling 1 at one end and to transmission box 3 at the other end.

[0035] The control box is electrically connected to a microcontroller signal converter; a power switch is installed on the control box and is connected to the hydraulic clutch 5; the torque sensor 2 and the power switch are electrically connected to the control box.

[0036] The digital display is electrically connected to the control box.

[0037] After starting the engine 6, power transmission begins. The hydraulic clutch 5 engages and begins operation, transmitting power through the telescopic short coupling 4. Under the transmission of power from the telescopic short coupling 4 and the telescopic long coupling 1, when the snow removal auger and snow-rolling impeller are working, if the snow accumulation is too high or contains hard or foreign objects, causing the engine 6 to experience excessive instantaneous load and severe vibration, the telescopic short coupling 4 and the telescopic long coupling 1 provide protection for the transmission box 3. Power is then transmitted through the transmission box 3 via speed reduction before reaching the telescopic long coupling 1. The torque sensor 2 rotates along with the telescopic long coupling 1. Before the equipment operates, a preset torque value is input into the control box, and the corresponding torque value is measured by the transmitted kinetic energy. The sensor's digital display normally displays the torque and speed. The torque sensor 2 transmits an analog signal. If the snow removal auger and snow-rolling impeller suddenly encounter hard objects such as stones while the snowplow is working, causing an overall power overload, the signal is converted into a controllable power switch signal by the microcontroller signal converter. This power switch signal is then transmitted to the emergency stop switch on the control box to shut off the power to the clutch, thus achieving the effect of the torque sensor 2 controlling the hydraulic clutch 5. If the snow removal auger and snow-rolling impeller are working normally without any obstructions and the snow accumulation does not exceed the snow removal height of the snowplow, the torque sensor 2 will not emit an analog signal, allowing the equipment to continue operating downwards. If the preset value is exceeded, the torque sensor 2 will emit an analog signal, automatically cutting off the power switch of the hydraulic clutch 5, causing the entire transmission system to stop operating, effectively protecting the entire transmission system without damage.

[0038] In this embodiment, a first toothed sprocket and a second toothed sprocket are rotatably disposed inside the transmission box 3; the first toothed sprocket and the second toothed sprocket are connected by a toothed chain drive; a tight-side oil inlet connector 12 and a loose-side oil inlet connector 13 are fixedly disposed outside the transmission box 3, with the tight-side oil inlet connector 12 located above the loose-side oil inlet connector 13; the tight-side oil inlet connector 12 and the loose-side oil inlet connector 13 are connected by a three-way connector 11; the three-way connector 11 is connected to the output end of the hydraulic oil pump 9 through an oil inlet pipe 10, and the input end of the hydraulic oil pump 9 is connected to a return oil pipe 17, which is connected to the transmission box 3. The bottom of the gearbox 3 is equipped with a tight-side oil injector 14 and a loose-side oil injector 15. The tight-side oil injector 14 is connected to the tight-side oil inlet connector 12, and the loose-side oil injector 15 is connected to the loose-side oil inlet connector 13. The tight-side oil inlet connector 12 and the loose-side oil inlet connector 13 are located on the axis connecting the first toothed sprocket and the second toothed sprocket. The front end of the tight-side oil injector 14 faces the first toothed sprocket, and the front end of the loose-side oil injector 15 faces the second toothed sprocket. The tight-side oil injector 14 and the loose-side oil injector 15 are used to spray lubricating oil onto the toothed chain to cool it down and increase its service life.

[0039] In this embodiment, the corresponding adjustment angle is calculated based on the sprayed fan-shaped area caused by the injection quantity and pressure. The angle between the axis of the first toothed sprocket, the axis of the second toothed sprocket, and the horizontal plane is 35°. The angle between the line connecting the axes of the first and second toothed sprockets and the axis of the slack-side injector 15 is 55°; the angle between the line connecting the axes of the first and second toothed sprockets and the axis of the tight-side injector 14 is 35°. The tight-side injector 14 sprays oil onto the upper toothed chain, and the slack-side injector 15 sprays oil onto the lower toothed chain. The spray atomization angle is a 60° fan shape.

[0040] In this embodiment, an oil suction filter 16 is installed at the bottom of the transmission box 3; the return oil line 17 is connected to the oil suction filter 16.

[0041] First, add an appropriate amount of oil to the transmission box 3. The amount of oil depends on the needs of the entire system and must also meet the optimal injection volume for the injectors. Through the return oil line 17, the oil is drawn into the hydraulic oil pump 9 by the hydraulic oil pump 9, and then pumped into the inlet oil line 10. It then reaches the three-way connector 11, which splits into two paths, entering the loose side inlet connector 13 and the tight side inlet connector 12. The oil is then sprayed onto the toothed chain through the tight side injector 14 and the loose side injector 15. This allows for large-area oil spraying at different engine speeds and different toothed chain speeds, achieving lubrication and cooling effects. Finally, the oil is filtered through the suction filter 16 and returned to the hydraulic oil pump 9 through the return oil line 17. This process is repeated to achieve circulating oil spraying lubrication for the entire system. During maintenance, only the installation-type suction filter 16 needs to be removed for cleaning. The entire system is stable, convenient, and highly efficient.

[0042] Meanwhile, when the axis angles of different toothed sprockets are different, it is only necessary to adjust the installation angles of the tight-side injector 14 (including the injector nozzle and mounting base) and the loose-side injector 15 (including the injector nozzle and mounting base) separately to achieve the best lubrication effect.

[0043] In this embodiment, a suction radiator 18, a support frame 19, and a shock absorber 20 are also included. The shock absorber 20 is a conventional product. The support frame 19 is fixed to the engine 6. The suction radiator 18 is fixed to the support frame 19, with one side attached to the engine 6. The shock absorber 20 is fixed to the suction radiator 18. This greatly improves the compatibility between the power system and the cooling system, as well as the safety of equipment operation.

[0044] When engine 6 starts, as its power and speed increase, driving the entire transmission system, and when the snowplow is working, if the snowplow auger and snow-rolling impeller suddenly encounter hard objects such as stones, causing overall power overload, the vibration of engine 6 will also increase, and the amplitude will also increase. Therefore, it is necessary to ensure that the radiator vibrates at the same frequency. The installed support frame 19 can make engine 6 and suction radiator 18 an integrated structure, achieving the same vibration frequency under working conditions and protecting the fan of suction radiator 18 from touching the water tank cover of suction radiator 18; the installed suction radiator 18 can better provide a large area of ​​airflow when engine 6 is working, quickly Rapid cooling; when there is too much snow before snow removal in winter, a corresponding amount of salt and gravel are often spread on the road. During the snow removal process, some snow and dust gravel will be blown into the air. The original blower-type radiator will blow the gravel into the radiator filter screen, causing the filter screen to become clogged and damaged, reducing the service life of the filter screen; the installed suction-type radiator 18 not only increases the heat dissipation area of ​​the engine 6, but also greatly reduces the risk of foreign objects hitting the radiator water tank and filter screen; the shock absorber 20 installed in the middle of the rear side of the radiator can reduce the vibration at the rear, and also plays a role in supporting the water tank of the suction-type radiator 18, which is convenient to use and improves safety performance.

[0045] In this embodiment, an angle is provided between one side of the bottom surface of the outer frame 21 and the horizontal plane, so that the outer frame 21 and the ground form a height difference H, which increases the utilization rate of the hollow design in the frame, and at the same time can better discharge the drifting waste snow outside the equipment, protect the various electrical equipment in the equipment, and increase the service life.

[0046] The outer frame 21 is raised to a certain height at the rear. Due to the density of snow and the influence of gravity, the front of the outer frame 21 is in contact with the ground while the rear is at a corresponding height H. During the operation of the equipment, snow inevitably enters the interior of the outer frame 21 from the bottom of the equipment and accumulates at the rear of the outer frame 21, increasing the damage rate of the electrical equipment inside the outer frame 21. This design allows the snow to slide off the equipment at a certain angle when the front of the outer frame 21 is in contact with the ground, under the influence of the corresponding height H of the rear of the outer frame 21. This greatly protects the electrical equipment inside the equipment, reduces the subsequent cleaning work, and facilitates the maintenance and use of the snowplow.
