Description
Technical Field
[0001] This utility model relates to the field of snow blowing technology, specifically a snow blowing device with a variable air outlet cross-section. Background Technology
[0002] Snowfall covers a vast area of my country, with snow quality exhibiting diverse forms such as compacted snow, frozen snow, and mixed snow. Furthermore, due to the intensifying impact of climate change, extreme snowstorms are becoming more frequent. Snow removal operations on airport runways, highways, and urban roads are directly related to public safety, making the demand for efficient snow removal equipment urgent.
[0003] Traditional snow removal devices typically have a fixed air outlet cross-section, making them unadjustable to different snow conditions. When ice forms, they are difficult to clear, resulting in low snow removal efficiency and a low cleanliness rate. Furthermore, traditional devices are made of welded carbon steel, making them heavy and prone to rusting in damp environments after snow removal operations, leading to machine malfunctions. Therefore, a corresponding technical solution needs to be designed to address these issues. Utility Model Content

Detailed Implementation
[0024] 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.
[0025] Please see Figures 1-4 The present invention provides a technical solution: such as Figures 1-5 As shown, the snow blowing device in this scheme consists of a blower 1, a motor 2, a distributor 3, upper and lower hydraulic cylinders 4, a steering hydraulic cylinder 5, an adjusting screw 6, a left air duct 7, a right air duct 8, an air outlet flap 9, an air outlet adjusting plate 10, an air direction adjusting plate 11, a bearing 12, a connecting seat 13, a rotating shaft 14, and a sealing block 15.
[0026] like Figure 1 As shown, the fan 1 and the distributor 3 are fixed together by bolts. The fan 1 is driven by the motor 2. The speed of the fan 1 can be adjusted by controlling the motor through the vehicle control system.
[0027] like Figure 1 As shown, fan 1 is a high-power centrifugal fan, and the casing of fan 1 adopts a volute-like design, which is conducive to quickly building up wind pressure and increasing wind speed.
[0028] The internal structure of the diverter 3 adopts a "human" shaped diverting device, which can effectively distribute the airflow generated and output by the rotor of the fan 1 evenly to the left air duct 7 and the right air duct 8, thereby achieving left and right airflow diversion and achieving the function of left and right blowing.
[0029] like Figure 1 As shown, the left air duct 7 and the right air duct 8 are welded from aluminum alloy, which has the advantage of being lightweight compared to traditional carbon steel and can be used in various complex and harsh environments.
[0030] like Figure 1 As shown, the left air duct 7 and the right air duct 8 are installed on the left and right sides of the diffuser 3, respectively. The left air duct 7 and the right air duct 8 are adjusted up and down by the upper and lower hydraulic cylinders 4. During operation, the left air duct 7 and the right air duct 8 are adjusted to a suitable height above the ground to improve the snow removal efficiency of the snow blowing device. When the vehicle is moved, the height above the ground of the left air duct 7 and the right air duct 8 is adjusted to improve the vehicle driving safety.
[0031] like Figures 1-5As shown, the left air duct 7 and the right air duct 8 are adjusted left and right by the steering cylinder 5. The lower end of the steering cylinder 5 is fixed to the connecting seat 13, the connecting seat 13 is fixed to the bearing 12, and the bearing 12 is fixed to both sides of the left air duct 7 and the right air duct 8 respectively. The inner ring of the bearing 12 rotates around the rotating shaft 14. The steering cylinder 5 controls the air direction adjustment plate 11 to swing left and right with an angle of 50°, thereby adjusting the air outlet direction of the left air duct 7 and the right air duct 8 to meet the requirements of snow removal operations under various road conditions.
[0032] like Figure 5 As shown, when the wind direction adjustment plate 11 swings left and right to its limit position, it is completely in contact with the sealing block 15, so that the airflow blows in one direction.
[0033] like Figure 5 As shown, the air vent flaps 9 are installed on the left and right sides of the left air duct 7 and the right air duct 8, respectively. The size of the air vent flaps 9 and the air outlet cross-section of the left air duct 7 and the right air duct 8 can be adjusted by adjusting the screw 6.
[0034] like Figure 5 As shown, an air outlet adjustment plate 10 is installed on the inner side of the air outlet flap 9 and is fixed by bolts. When the air outlet flap 9 is in contact with the left air duct 7 and the right air duct 8, the air outlet adjustment plate 10 can adjust the size of the air outlet cross section.
[0035] like Figure 6 As shown, during snow blowing operations, the snow blowing device is driven by a hydraulic system according to different operating environment requirements. The control system adjusts the ground height of the left air duct 7 and the right air duct 8 and the air outlet direction. The air outlet cross-sectional area is adjusted by adjusting the screw 6 and the air outlet adjustment plate 10. When the road has a thin layer of snow, it can be adjusted to a large air outlet cross-section for blowing. When there is a mixture of ice and snow on the road, it can be adjusted to a small air outlet cross-section for blowing. The high-speed airflow can quickly blow away the snow, which can significantly improve the snow removal efficiency and removal rate. Moreover, the whole machine is simple to operate and maintain, which can reduce the use and maintenance costs.
[0036] It should be noted that the specific model and specifications need to be determined based on the actual specifications of the device. The specific selection and calculation methods adopt existing technology in this field, and therefore will not be described in detail. The power supply and its principle are clear to those skilled in the art, and will not be described in detail here.
