Description

Technical Field

[0001] This utility model relates to the field of snowplow technology, specifically to a dual-series hydraulic drive device for snowplows. Background Technology

[0002] After snowfall in winter, snow accumulation on roads seriously affects traffic safety, making the demand for snow removal equipment increasingly urgent.

[0003] Traditional snowplows typically use the chassis engine for power take-off, which cannot simultaneously drive multiple implements. This results in limited functionality, low snow removal efficiency, and an inability to adapt to various complex snow removal conditions. Furthermore, traditional snowplows transmit engine power through a transfer case, leading to low transmission efficiency and complex troubleshooting and maintenance. Therefore, appropriate technical solutions are needed to address these shortcomings. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a dual-series hydraulic drive device for snowplows, solving its technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a dual-series hydraulic drive device for a snowplow, comprising an engine, an intake device, an exhaust device, a cooling device, a fuel heater, a coupling, hydraulic pump I, hydraulic pump II, hydraulic pump III, a subframe, and a shock absorber, wherein the coupling is composed of a transition flange, a mounting flange, a rotating gear, a rotating shaft, and fastening bolts;

[0008] The intake and exhaust devices are mounted on the upper part of the engine, and the cooling and fuel heaters are mounted on the two sides of the engine.

[0009] The engine flywheel is connected to a coupling, and the coupling is connected in sequence to hydraulic pump I and hydraulic pump II;

[0010] The engine power take-off port is connected to hydraulic pump III.

[0011] Preferably, four mounting brackets are installed on each side of the engine, and the mounting brackets are connected to the subframe via shock-absorbing pads.

[0012] Preferably, the shock-absorbing pad is fixed to the mounting bracket and the subframe by bolts.

[0013] Preferably, the hydraulic pump I and hydraulic pump II are connected in series via a splined shaft.

[0014] (III) Beneficial Effects

[0015] This snowplow uses a dual-series hydraulic drive system. The high-power engine in the hydraulic drive system is directly connected to two series hydraulic pumps via a coupling. The engine power take-off port is directly connected to the hydraulic pumps, forming three sets of hydraulic drive systems, each driving different working tools of the snowplow. The three sets of hydraulic drive systems can work independently or simultaneously, driving different working tools of the snowplow to meet the driving requirements of the snowplow under different working conditions. This hydraulic drive system has advantages such as high transmission efficiency, compact layout, simple maintenance, and strong adaptability. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 The present invention provides a technical solution: such as Figures 1-3 As shown, the system consists of an engine 1, an intake device 2, an exhaust device 3, a cooling device 4, a fuel heater 5, a coupling 6, a hydraulic pump I 7, a hydraulic pump II 8, a hydraulic pump III 9, a subframe 10, a mounting bracket 11, and a shock absorber 12.

[0024] like Figure 4As shown, the coupling 6 consists of a transition flange 601, a mounting flange 602, a rotating gear 603, a rotating shaft 604, and fastening bolts 605;

[0025] like Figures 1-2 As shown, four mounting brackets 11 are installed on both sides of the engine 1. The mounting brackets 11 are connected to the subframe 10 through shock-absorbing pads 12. The shock-absorbing pads 12 are fixed to the mounting brackets 11 and the subframe 10 respectively with bolts, which effectively buffers the vibration and impact generated during engine operation and improves the stability and reliability of the system operation.

[0026] like Figures 1-2 As shown, an intake device 2 and an exhaust device 3 are installed on the upper part of the engine 1, and a cooling device 4 and a fuel heater 5 are installed on both sides of the engine 1.

[0027] like Figures 1-2 As shown, the flywheel of engine 1 is connected to coupling 6, and coupling 6 is connected to hydraulic pump I 7 and hydraulic pump II 8 in sequence. By using coupling 6 to directly connect engine 1 with hydraulic pump I 7 and hydraulic pump II 8, the power transmission efficiency of the system is improved, and the overall layout of the system is more compact, making installation and maintenance simple.

[0028] like Figures 1-2 As shown, hydraulic pump I7 and hydraulic pump II8 are directly connected in series via a splined shaft. Engine 1 can provide power to both pumps simultaneously. Hydraulic pump I7 and hydraulic pump II8 can respectively meet the requirements of high pressure and low flow rate and low pressure and high flow rate. The system can adapt to various working conditions, optimize system efficiency, and improve the system's fault tolerance.

[0029] like Figures 1-2 As shown, the power take-off port of engine 1 is connected to hydraulic pump III9, and engine 1 directly drives hydraulic pump III9, resulting in high system transmission efficiency;

[0030] When the hydraulic drive unit is working, the flywheel of engine 1 directly drives hydraulic pump I7 and hydraulic pump II8 through coupling 6, and the power take-off port at the front of engine 1 directly drives hydraulic pump III9. The three sets of hydraulic pump drive units can work independently or simultaneously to drive different working tools of the snowplow. This hydraulic drive unit has the advantages of high transmission efficiency, compact layout, simple maintenance and strong adaptability.
