Description

Technical Field

[0001] The utility model relates to the technical field of blower manufacturing, in particular to a blower air duct conversion mechanism applied to a special snow blower vehicle. Background Art

[0002] A special snow blower vehicle, also known as a snow blower or a jet snow blower, is a truck designed specifically for snow removal. These vehicles are usually equipped with efficient blowing devices that can quickly remove snow and ice layers on roads, airport runways and other areas. With the changing winter climate, the snow problem has become increasingly serious, especially in cold regions. Traditional manual snow removal methods can no longer meet the need for rapid snow removal. As an efficient snow removal tool, the performance improvement of special snow blower vehicles is crucial for ensuring traffic and personnel safety. Existing special snow blower vehicles usually use blowers with fixed wind directions, resulting in inflexible wind direction adjustment during operation and affecting snow removal efficiency. Therefore, a blower air duct conversion mechanism that can achieve flexible wind direction conversion is needed. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a blower air duct conversion mechanism, which can solve the problem that existing special snow blower vehicles use blowers with fixed wind directions, resulting in inflexible wind direction adjustment during operation.

[0004] To solve the above problems, the technical solution adopted by the utility model is: This blower air duct conversion mechanism includes a lifting pipe whose upper part is connected to the air outlet of the blower. A first bent pipe part that bends to one side is provided at the bottom of the lifting pipe. The air outlet of the first bent pipe part is hinged to a reversing pipe. The reversing pipe includes a horizontal pipe part, a second bent pipe part and an extension part arranged in sequence. The reversing pipe is driven to rotate by a reversing oil cylinder.

[0005] In the above technical solution, a more specific technical solution can also be: The extension part includes windshields connected to the outer walls on both sides of the air outlet of the second bent pipe part. The top of the windshields is connected to the side wall of the horizontal pipe part.

[0006] Further, connecting plates are provided on the outer walls on both sides of the top of the horizontal pipe part of the reversing pipe. One end of the connecting plates is hinged to the side wall of the first bent pipe part.

[0007] Further, the cylinder body of the reversing oil cylinder is connected to the outer wall of the lifting pipe, and the extending end of the reversing oil cylinder is connected to the connecting plate.

[0008] Further, the lifting pipe is driven to lift by a lifting oil cylinder. The cylinder body of the lifting oil cylinder is connected to the casing of the blower, and the extending end of the lifting oil cylinder is connected to the upper outer wall of the lifting pipe.

[0009] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0010] Through the application of the reversing pipeline, the snow blowing special vehicle can flexibly adjust the wind direction during operation, improving the snow clearing efficiency. After the blower of the utility model is started, the air flow direction is as shown by the arrow. When the reversing oil cylinder drives the reversing pipeline to rotate downward in place, the horizontal pipe part of the reversing pipeline communicates with the first elbow part of the lifting pipeline, and the air blows out from the extension part, opposite to the blowing direction of the first elbow part. When the reversing oil cylinder drives the reversing pipeline to rotate upward in place, the air blows directly out from the first elbow part. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 is a schematic structural view of the utility model when the reversing pipeline rotates downward in place;

[0012] Figure 2 is a schematic structural view of the utility model when the reversing pipeline rotates upward in place. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The following further details the utility model in conjunction with the embodiments of the drawings:

[0014] As Figure 1 and Figure 2 shown in the blower air duct conversion mechanism, which includes a lifting pipeline 2 with the upper part connected to the air outlet of the blower 1. The bottom of the lifting pipeline 2 is provided with a first elbow part 2-1 bent to one side. The air outlet of the first elbow part 2-1 is hinged to the reversing pipeline. The reversing pipeline includes a horizontal pipe part 3, a second elbow part 4 and an extension part arranged in sequence. The reversing pipeline is driven to rotate by a reversing oil cylinder 5.

[0015] The extension part includes windshields 6 connected to the outer walls on both sides of the air outlet of the second elbow part 4. The top of the windshields 6 is connected to the side wall of the horizontal pipe part 3.

[0016] On the outer walls on both sides of the top of the horizontal pipe part 3 of the reversing pipeline, there are connecting plates 7. One end of the connecting plates 7 is hinged to the side wall of the first elbow part 2-1.

[0017] The cylinder body of the reversing oil cylinder 5 is connected to the outer wall of the lifting pipeline 2, and the extending end of the reversing oil cylinder 5 is connected to the connecting plate 7.

[0018] The lifting pipeline 2 is driven to lift by a lifting oil cylinder 8. The cylinder body of the lifting oil cylinder 8 is connected to the casing of the blower 1, and the extending end of the lifting oil cylinder 8 is connected to the upper outer wall of the lifting pipeline 2.

[0019] After the blower 1 of the utility model is started, the air flow direction is as shown by the arrow. When the reversing oil cylinder 5 drives the reversing pipeline to rotate downward in place, the horizontal pipe part 3 of the reversing pipeline communicates with the first elbow part 2-1 of the lifting pipeline 2, and the air is blown out from the extension part, opposite to the blowing direction of the first elbow part 2-1; when the reversing oil cylinder 5 drives the reversing pipeline to rotate upward in place, the air is directly blown out from the first elbow part 2-1.

[0020] Through the application of the reversing pipeline, the utility model can realize the flexible adjustment of the wind direction during the operation of the snow blowing special vehicle, improving the snow clearing efficiency. The extension part extends the snow blowing path and reduces the loss.
