Description

Technical Field

[0001] The invention relates to the technical field of highway snow-clearing vehicles, and in particular to a throwable highway snow-clearing vehicle. Background Art

[0002] A highway snowplow (also known as a snowplow) is a mechanical device specially designed to remove snow and ice from the ground on roads, streets, airport runways, etc. Its main purpose is to ensure traffic safety and avoid sliding and accidents caused by snow or ice. The external-throwing highway snowplow includes a spiral snow milling machine (or spiral snow milling machine), which is a device specially used to handle thick snow, compacted snow and hardened snow layers. The working principle of the spiral snow milling machine is to cut and compress the snow layer through a rotating spiral milling cutter, and then throw the snow to one side or away from the road through the thrust of the spiral. In the prior art, the snow-clearing spiral cutter at the front end of the spiral snow milling machine can only handle snow of a specified thickness. If the snow-clearing spiral cutter is small in size, the processing capacity is very limited when facing thick snow, which easily leads to the inability to effectively cut and push the snow layer. In addition, when using a larger-sized snow-clearing spiral cutter to clean shallow snow, due to the shallow snow layer, it does not actually require such a large cutting capacity, and the excess power consumption will be wasted. Furthermore, the snow-clearing spiral cutter at the front end of a spiral snow milling machine will have certain limitations when facing snow of different thicknesses. Summary of the invention

[0031] Example

[0032] like Figures 1 to 8As shown, the present invention proposes an outwardly throwable highway snowplow, comprising a highway snowplow body 1 and a connecting frame 11 installed at the front end of the highway snowplow body 1, and also comprising: a first bracket 2 fixedly connected to the bottom of the connecting frame 11, a second bracket 3 is provided on the first bracket 2, the upper surface of the second bracket 3 is fixedly connected to a base plate 7, the upper surface of the base plate 7 is fixedly connected to a pair of L-shaped brackets 71, the ends of the L-shaped brackets 71 away from the base plate 7 are spirally connected with mounting bolts 72 with ends inserted into the sockets 452, the mounting bolts 72 are relatively long, and their function is to allow the bottom ends of the mounting bolts 72 to be inserted into the sockets 452 on the first snow milling mechanism 4 or the second snow milling mechanism 5; the first snow milling mechanism 4 and the second snow milling mechanism 5, the size difference between the first snow milling mechanism 4 and the second snow milling mechanism 5 can be installed as required to ensure that the first snow milling mechanism 4 and the second snow milling mechanism 5 cover a larger range of snow removal. The second bracket 3 is installed to be replaced according to the snow thickness; the lifting mechanism is arranged on the first bracket 2 to drive the second bracket 3 to move up and down so that the bottom of the corresponding first snow milling mechanism 4 and the second snow milling mechanism 5 is close to the ground; the adjusting chute 8 is arranged on the second bracket 3, and the adjusting chute 8 is provided with an adjusting mechanism for driving the first snow milling mechanism 4 or the second snow milling mechanism 5 to operate; the supporting baffle 9 is installed on the second bracket 3, and the supporting baffle 9 can block the transmission mechanism to prevent the transmission mechanism from being exposed to the outside and protect people approaching the transmission mechanism. The supporting baffle 9 is provided with a transmission mechanism that connects the driving mechanism with the first snow milling mechanism 4 or the second snow milling mechanism 5. The present invention uses the design of the lifting mechanism, the adjusting mechanism and the transmission mechanism to enable the external-throwing highway snow clearing vehicle to process more snow at one time for thick snow with the large-sized first snow milling mechanism 4, thereby reducing the working time of the machine, reducing the burden of the machine on the engine, and reducing energy consumption. If the small-sized second snow milling mechanism 5 is used to process thick snow, the machine will be more laborious, requiring longer time and higher power, which not only reduces the snow clearing efficiency but also increases fuel consumption. Therefore, being able to replace the appropriate spiral blade according to different snow conditions can better balance energy efficiency and reduce ineffective consumption.

[0033] Furthermore, the adjustment mechanism includes a motor cover 81 slidably arranged in the adjustment slot 8, a motor 82 is fixedly connected to the inside of the motor cover 81, a bottom block 84 is fixedly connected to the outer wall of one end of the motor cover 81, a sliding groove 86 connected to the adjustment slot 8 is opened on the second bracket 3, and a plurality of tensioning bolts 87 arranged linearly and resting against the bottom block 84 are spirally connected to the bottom of the second bracket 3, and the tensioning bolts 87 are used to fix the motor 82 in the motor cover 81 at a specified position.

[0034] The transmission mechanism includes a sleeve plate 85 fixedly connected to the outer wall of the bottom block 84, a sliding support plate 91 is slidably connected inside the sleeve plate 85, and one end of the sliding support plate 91 inserted into the sleeve plate 85 is fixedly connected to a pair of anti-dropping blocks 97 to prevent the sliding support plate 91 from slipping out of the sleeve plate 85, and the anti-dropping blocks 97 are used to limit the distance that the support baffle 9 moves in the direction away from the second bracket 3. The end of the sliding support plate 91 away from the sleeve plate 85 is fixedly connected to the support baffle 9, and the output shaft of the motor 82 is fixedly connected to the inner hexagonal slide 83, and the inner hexagonal slide 83 is set to be hexagonal, and the function is to ensure the plugging with the hexagonal plug rod 96. The inner hexagonal slide 83 is provided with a spring 88, and the spring 88 is so that when it is released in the direction away from the second bracket 3, the support baffle 9 at this time will finally move in the direction of the second bracket 3 through the elastic tension of the spring 88. One end of the spring 88 is fixedly connected to the inner wall of the hexagonal slide cylinder 83 , and the other end of the spring 88 is fixedly connected to the hexagonal plug rod 96 . The end of the hexagonal slide cylinder 83 away from the motor 82 is slidably connected to the hexagonal plug rod 96 .

[0035] Secondly, the transmission mechanism also includes a first transmission wheel 92 and a second transmission wheel 93 rotatably connected to the support baffle 9. The first transmission wheel 92 and the second transmission wheel 93 are transmission wheels, which are a key component in the mechanical transmission system and are usually used to transfer power from one component to another. The first transmission wheel 92 and the second transmission wheel 93 are provided with a synchronous belt 94, which is a transmission belt commonly used in mechanical equipment, and realizes power transmission by meshing with the transmission wheel. Unlike ordinary conveyor belts, the synchronous belt meshes with the teeth on the pulley through the teeth on the belt, thereby ensuring the precise synchronous movement between the driving shaft and the driven shaft. The first transmission wheel 92 is fixedly connected to the end of the hexagonal plug rod 96 away from the inner hexagonal slide cylinder 83, and the second transmission wheel 93 is fixedly connected with a hexagonal plug block 95.

[0036] Furthermore, the first snow milling mechanism 4 is provided with a first snow milling cutter 41 inside, and the second snow milling mechanism 5 is provided with a second snow milling cutter 51 inside. The first snow milling cutter 41 and the second snow milling cutter 51 are snow milling cutters, which cut the snow layer by high-speed rotation, and use the shape and rotation direction of the cutter to throw the snow material to the side or rear, so as to achieve the effect of external snow removal. The first snow milling mechanism 4 and the second snow milling mechanism 5 have the same length, and one end of the first snow milling mechanism 4 and the second snow milling mechanism 5 are provided with an inner hexagonal sleeve 453 that rotates to drive the corresponding first snow milling cutter 41 and the second snow milling cutter 51 to rotate. The inner shape of the inner hexagonal sleeve 453 is hexagonal, and is plugged into the hexagonal plug block 95. The hexagonal socket 453 is movably connected to the hexagonal insert 95. The hexagonal socket 453 is provided with a tightening bolt 454 which presses against the hexagonal insert 95 to prevent the hexagonal insert 95 from falling out of the hexagonal socket 453. The tightening bolt 454 prevents the hexagonal insert 95 installed in the hexagonal socket 453 from falling out at will, ensuring that the installation is tightened and safe.

[0037] Furthermore, the outer walls of the first snow milling mechanism 4 and the second snow milling mechanism 5 are fixedly connected with a pair of connecting plugs 451, one of which is provided with a pair of plug holes 452, and the upper and lower surfaces of the second bracket 3 are fixedly connected with a card cover plate 6 that clamps the corresponding connecting plugs 451, one of which is screwed with a pair of fixing bolts 61 inserted into the plug holes 452 on the connecting plugs 451, and the fixing bolts 61 and the mounting bolts 72 are of the same size but different lengths. The spacing between the pair of fixing bolts 61 is the same as the spacing between the mounting bolts 72, so that the fixing bolts 61 and the mounting bolts 72 can use the same plug hole 452.

[0038] Furthermore, the lifting mechanism includes a mounting groove 21 provided on the first bracket 2, and a cylinder 24 is fixedly connected inside the mounting groove 21. When the cylinder 24 is extended to the limit length, the end of the limit plug 23 cannot be disengaged from the sliding slot 22. The piston rod of the cylinder 24 is fixedly connected to the second bracket 3, and a pair of sliding slots 22 are also provided on the first bracket 2. A pair of limit plugs 23 inserted into the sliding slots 22 are fixedly connected to the bottom of the second bracket 3.

[0039] In this embodiment, when it is necessary to use a throwable highway snow clearing vehicle, such as Figure 1 As shown, the first snow milling mechanism 4 or the second snow milling mechanism 5 is selected according to the thickness of the snow. When the thickness of the snow is thick, it is only necessary to start the motor 82 in the motor cover 81, and the output shaft of the motor 82 can drive the inner hexagonal slide 83 to rotate, and the inner hexagonal slide 83 in turn drives the hexagonal plug rod 96 and the first transmission wheel 92 to rotate. And the first transmission wheel 92 drives the second transmission wheel 93 to rotate through the synchronous belt 94, so that the second transmission wheel 93 drives the inner hexagonal sleeve 453 to rotate through the hexagonal plug block 95, and then the inner hexagonal sleeve 453 drives the first snow milling cutter 41 in the first snow milling mechanism 4 to rotate and clean the thick snow.

[0040] When the thickness of snow is thin, first use a tool to remove the pair of fixing bolts 61 on the card cover plate 6, and then use a tool to remove the tightening bolt 454 on the first snow milling cutter 41 from the inner hexagon socket 453, so as to remove the first snow milling mechanism 4 from the second bracket 3. Then use a tool to remove the mounting bolts 72 on the pair of L-shaped brackets 71, so that the second snow milling mechanism 5 is removed from the second bracket 3 and installed in the original position of the first snow milling mechanism 4. Before installing the second snow milling mechanism 5, it is necessary to slide the motor cover 81 in the adjustment slide groove 8 to adjust the position, and the motor cover 81 drives the motor 82, the bottom block 84, the inner hexagon slide 83 and the support baffle 9 to move until the hexagonal insert 95 on the second transmission wheel 93 can be inserted into the inner hexagon socket 453 on the second snow milling mechanism 5. At this time, the support baffle 9 can be pulled, and finally the support baffle 9 drives the hexagonal insert rod 96 to slide in the inner hexagon slide 83, and the sliding support plate 91 slides in the sleeve plate 85. Thus, the hexagonal insert 95 can be inserted into the hexagonal sleeve 453, and then the tightening bolt 454 on the hexagonal sleeve 453 is tightened with a tool. Then the loosening bolt 87 at the bottom of the corresponding bottom block 84 is tightened, so that the bottom block 84 and the motor cover 81 are firmly installed in the sliding groove 86 and the adjustment groove 8. Finally, the second snow milling mechanism 5 is installed and fixed on the second bracket 3 using the original pair of fixing bolts 61, and the disassembled first snow milling mechanism 4 is installed at the position of the original second snow milling mechanism 5, so that the first snow milling mechanism 4 or the second snow milling mechanism 5 used according to the thickness of the snow can be completed.
