Technical Field

[0001] The present invention belongs to the technical field of environmental sanitation equipment, and relates to an air outlet adjusting mechanism, in particular to an air outlet adjusting mechanism for a snow blower vehicle. Background Art

[0002] A snow blower vehicle uses the high-temperature air ejected by an aero-engine to blow the snow on the ground to achieve the purpose of snow removal, and is widely used in northern cities. Existing snow blower vehicles often only blow the high-temperature air at a fixed angle, and adjust the air outlet position and the air outlet range of the air outlet through the movement of the vehicle and the size of the air output. It is impossible to adjust the air outlet angle and the size of the air outlet, and the air outlet range and the air outlet position cannot be flexibly adjusted, resulting in the need for the snow blower vehicle to move in circles for snow removal, with a large moving distance, poor snow blowing flexibility, low snow removal efficiency, and poor snow removal effect.

[0003] Based on this, it is necessary to provide an adjusting mechanism that can flexibly adjust the air outlet position and the air outlet range, so as to shorten the driving mileage of the snow blower vehicle and improve its flexibility during the snow removal process of roads with the same length and area. Summary of the Invention

[0030] In order to better understand the purpose, structure and function of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] As Figures 1 to 5 shown, the present invention provides an air outlet adjusting mechanism for a snow blower, which includes an exhaust pipe 1, an adjusting sleeve 2, an air outlet angle adjusting mechanism and an air outlet size adjusting mechanism 3. The intake end of the adjusting sleeve 2 covers the outlet end of the exhaust pipe 1 and is used for arranging the air outlet angle adjusting mechanism and the air outlet size adjusting mechanism 3. The adjusting sleeve 2 is hinged to the exhaust pipe 1 through an angle rotation shaft 4 and lapped with the outlet end of the exhaust pipe 1, and there is a clearance fit between the two;

[0032] To facilitate the arrangement of the air outlet angle adjusting mechanism, as Figure 6 shown, a support arm 5 is arranged on the outer side surface of the exhaust pipe 1, and an angle rotation arm 6 is arranged on the outer side surface of the adjusting sleeve 2. One end of the air outlet angle adjusting mechanism is hinged to the support arm 5, and the other end is hinged to the angle rotation arm 6; the adjusting sleeve 2 swings around the angle rotation shaft 4 under the drive of the air outlet angle adjusting mechanism, so as to adjust the air outlet angle of the adjusting sleeve 2;

[0033] In order to effectively adjust the air outlet size, the air outlet size adjusting mechanism 3 in this embodiment is arranged at the intake end of the adjusting sleeve 2. The intake end of the air outlet size adjusting mechanism 3 is connected to the outlet end of the exhaust pipe 1 and the outlet end blows air outwards. The outlet end of the air outlet size adjusting mechanism 3 has the freedom to be larger or smaller than the diameter of the outlet end of the adjusting sleeve 2 under the adjustment of the air outlet size adjusting mechanism 3.

[0034] Specifically, as Figure 1 、 Figure 3As shown, the air outlet angle adjustment mechanism includes an angle adjustment push rod 7, which can be electric, pneumatic or hydraulic, and no specific limitation is made in this embodiment. The fixed end of the angle adjustment push rod 7 is hinged to the support arm 5 on the exhaust pipe 1, and the telescopic end is hinged to the angle rotation arm 6 on the adjustment sleeve 2. For the convenience of angle adjustment, in this embodiment, the number of the angle adjustment push rod 7, the angle rotation arm 6 and the support arm 5 is two, and they are symmetrically arranged on both sides of the adjustment sleeve 2 and the exhaust pipe 1. In order to facilitate the adjustment of the angle of the adjustment sleeve 2, in this embodiment, the angle rotation arm 6 and the angle rotation shaft 4 are located on different cross-sections of the adjustment sleeve 2, that is, the hinge point of the angle adjustment push rod 7 and the angle rotation arm 6 is not on the same cross-section of the adjustment sleeve 2 as the angle rotation shaft 4.

[0035] Furthermore, for the convenience of installation, in this embodiment, the angle rotation shaft 4 is arranged on the inner side surface of the adjustment sleeve 2, and an angle rotation sleeve 8 is arranged on the outer side surface of the air outlet end of the exhaust pipe 1. As Figure 6 shown, the angle rotation shaft 4 is arranged in the angle rotation sleeve 8 and has the freedom to rotate relative to the angle rotation sleeve 8.

[0036] In addition, as Figure 1 、 Figure 4 、 Figure 10 shown, the air outlet size adjustment mechanism 3 includes a plurality of adjustment vanes 9 for controlling the reverse flow of air and an air outlet adjustment part for adjusting the angle of the adjustment vanes 9. Among them, the adjustment vanes 9 are fan-shaped with the end gradually narrowing, and are arranged in the adjustment sleeve 2. In order to better guide the flow, the flow guiding surface of the adjustment vanes 9 in this embodiment is an arc surface with a certain radian. The large end of the adjustment vane 9 is hinged to the air inlet end of the adjustment sleeve 2, and the small end extends towards the air outlet end of the adjustment sleeve 2. A plurality of vanes are combined into a cylindrical or frustum shape in the adjustment sleeve 2. The air outlet size adjustment part is arranged on the outer side surface of the air inlet end of the adjustment sleeve 2, and the hinge shaft of the adjustment vane 9 and the adjustment sleeve 2 is hinged to the output end of the air outlet size adjustment part. The angle between the adjustment vane 9 and the adjustment sleeve 2 is adjusted through the air outlet size adjustment part to adjust the size of the air outlet.

[0037] Specifically, as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 10As shown in the figure, in this embodiment, the air outlet adjusting part includes a synchronous ring 10, a blade adjusting push rod 11 and a hinged connecting rod A12. The number of the blade adjusting push rods 11 is two or more, preferably three. The three blade adjusting push rods 11 are evenly arranged on the outer side surface of the adjusting sleeve 2. The synchronous ring 10 is arranged outside the adjusting sleeve 2 and fixed to the output end of the blade adjusting push rod 11. One end of the hinged connecting rod A12 is hinged to the synchronous ring 10, and the other end is hinged to the large end of the adjusting blade 9. By the telescopic movement of the blade adjusting push rod 11, the synchronous ring 10 makes a relative movement relative to the air inlet end of the adjusting sleeve 2, and then drives the adjusting blade 9 to swing by a corresponding angle through the hinged connecting rod A12, so as to adjust the size of the air outlet.

[0038] Among them, in order to realize the linkage of the air outlet adjusting part, as Figure 2 , Figure 8 shown, the synchronous ring 10 includes a ring body 13, a sliding core shaft 14 and blade hinged ears 15. As Figure 2 , Figure 5 , Figure 7 shown, the adjusting sleeve 2 is provided with a guide block 16 corresponding to the blade adjusting push rod 11. A through hole is opened on the guide block 16. One end of the sliding core shaft 14 is fixed to the side of the ring body 13 close to the air outlet of the adjusting sleeve 2, and the other end passes through the through hole of the guide block 16 and is fixed to the output end of the blade adjusting push rod 11, having a degree of freedom of sliding relative to the guide block 16. By providing a limit for the ring body 13 through the sliding core shaft 14 and the guide block 16, the air outlet adjusting part can be stably arranged on the adjusting sleeve 2, so as to ensure the stable adjustment of the air outlet adjusting part and the adjusting blade 9. In addition, the number of the blade hinged ears 15 is multiple corresponding to the number of the adjusting blades 9. The multiple blade hinged ears 15 are evenly arranged on the side of the ring body 13 close to the air inlet of the adjusting sleeve 2. An articulated seat 17 is arranged on the end surface of the air inlet end of the adjusting sleeve 2. A hinged connecting rod B18 is fixed to the large end of the adjusting blade 9. As Figure 9 shown, both ends of the hinged connecting rod A12 are respectively hinged to the blade hinged ear 15 and one end of the hinged connecting rod B18. The other end of the hinged connecting rod B18 is hinged to the articulated seat 17. The adjusting blade 9 is arranged on the adjusting sleeve 2 through the hinged connecting rod B18, and then is hinged to the ring body 13 through the hinged connecting rod B18, the hinged connecting rod A12 and the blade hinged ear 15 to realize linkage.

[0039] Furthermore, in order to prevent the adjusting blade 9 from being damaged by bumping against foreign objects on the road during the snow blowing process, and also to prevent lighter sundries from hanging on the adjusting blade 9, the end surface of the small end of the adjusting blade 9 is arranged inside the end surface of the air outlet end of the adjusting sleeve 2. By setting the length of the adjusting blade 9, so that it always adjusts the air outlet size inside the adjusting sleeve 2, it can effectively prevent lighter sundries from hanging on the adjusting blade 9 or bumping against foreign objects on the road, and prolong its service life.
