Description

Technical Field

[0001] This utility model relates to the field of snowplow technology, specifically to an adjustable conveyor platform for snowplows. Background Technology

[0002] Snowplows are specialized mechanical equipment used to clear snow from roads, widely used in areas with frequent winter snowfall to efficiently ensure smooth traffic flow. However, due to varying design purposes, existing equipment has limitations in loading roadside snow onto trucks. For example, when using loaders to transfer roadside snow to transport vehicles, the large operating radius of loaders can easily cause traffic congestion, and they are inefficient and energy-intensive. When using belt conveyors to load roadside snow onto transport vehicles, manual assistance is required to feed the snow onto the conveyor belt, reducing efficiency and compromising worker safety. Scraper conveyors, due to their conveying characteristics, inevitably compress the snow during loading, causing water to be released. Excessive water release makes it difficult to clean the snow from the truck bed during unloading. While snow-throwing loaders are relatively efficient, they cannot handle hard lumps of snow from the roadside.

[0003] A prior art patent with publication number CN205187383U discloses a solution including a receiving shovel with a discharge port at its rear end; a receiving mechanism located inside the receiving shovel for moving the material inside the shovel to the discharge port; the receiving mechanism includes a front arm and a rear arm, a first positioning shaft protruding from the receiving shovel near the discharge port, one end of the rear arm hinged to the first positioning shaft, and the other end hinged to one end of the front arm; a power device including a rotating wheel and a motor driving its rotation; a second positioning shaft is provided on the end face of the rotating wheel off-center, and the second positioning shaft is hinged to the front arm. The receiving device and snow loading machine with this invention have a simple structure, are suitable for complex road snow loading operations, do not squeeze water out of the snow during the snow loading process, and do not require additional manual snow shoveling.

[0004] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:

[0005] When existing snowplows are used for snow removal, they need to transport snow into the truck bed for transfer. This is limited by the height of the existing transfer truck bed, which makes the snowplow's transport platform relatively high, thus affecting the vehicle's maneuverability when not in operation.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides an adjustable conveying platform for snowplows. This solves the problem that in traditional snowplows, the snow needs to be transported into the truck bed for transfer, which is limited by the height of the existing transfer truck bed. This results in a relatively high conveying platform for the snowplow, which in turn affects the vehicle's maneuverability when not in operation.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An adjustable conveying platform for a snowplow includes a frame. A conveying mechanism is vertically swaying on the frame. The conveying mechanism includes a loading platform and a unloading platform. The upper end of the loading platform and the lower end of the unloading platform are hinged together by a support structure. A head adjustment structure that drives the lower end of the loading platform to rise and fall, and a tail adjustment structure that drives the upper end of the unloading platform to rise and fall, are connected to the frame.

[0010] As an optimized solution, the support structure includes side frames fixedly connected side by side to the bracket, with a hinge shaft horizontally fixed between the two side frames, and the upper end of the loading platform and the lower end of the unloading platform respectively hinged to the hinge shaft.

[0011] As an optimized solution, a limiting frame connected to the side frame is fixed to the frame, and when the lower end of the unloading platform moves downward, it abuts against the upper end of the limiting frame.

[0012] As an optimized solution, the upper end of the limiting frame is fixed with lateral limiting rods in parallel, and the unloading platform is constrained in the area between the two lateral limiting rods.

[0013] As an optimized solution, an upwardly expanding inlet end is provided between the upper ends of the two lateral limiting rods.

[0014] As an optimized solution, the head adjustment structure includes a head adjustment telescopic cylinder that is hinged in parallel to the frame, and the telescopic end of the head adjustment telescopic cylinder is hinged to the lower end of the loading platform.

[0015] As an optimized solution, the head adjustment structure includes a head adjustment telescopic cylinder that is hinged in parallel to the frame, and the telescopic end of the head adjustment telescopic cylinder is hinged to the lower end of the loading platform.

[0016] As an optimized solution, the tail adjustment structure includes a tail adjustment telescopic cylinder that is hinged in parallel to the frame, and the telescopic end of the tail adjustment telescopic cylinder is hinged to the upper end of the unloading platform.

[0017] As an optimized solution, the upper end of the side frame is fixedly connected to a fan-shaped side baffle plate located outside the loading platform and unloading platform.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] By changing the traditional conveying platform to a split design, consisting of a loading platform and a unloading platform, the height of the lower end of the loading platform can be adjusted via a head adjustment structure, thus adjusting the loading end; the height of the upper end of the unloading platform can be adjusted via a tail adjustment structure. In use, the upper end of the unloading platform can be raised to facilitate the transport of snow into the transfer truck bed. In non-working state, the tail adjustment structure lowers the upper end of the unloading platform and supports it on the limit frame, thereby reducing the height of the vehicle and improving its passability when not in use.

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] like Figure 1 and Figure 2 As shown, the snowplow's adjustable conveying platform includes a frame 1. A conveying mechanism is provided on the frame 1, which swings vertically. The conveying mechanism includes a loading platform 2 and a unloading platform 3. The upper end of the loading platform 2 and the lower end of the unloading platform 3 are hinged together by a support structure. A head adjustment structure that drives the lower end of the loading platform 2 to rise and fall, and a tail adjustment structure that drives the upper end of the unloading platform 3 to rise and fall are connected to the frame 1.

[0026] The support structure includes side frames 4 fixedly attached to the bracket in parallel, and a hinge shaft 5 is horizontally fixed between the two side frames 4. The upper end of the loading platform 2 and the lower end of the unloading platform 3 are respectively hinged to the hinge shaft 5.

[0027] A limiting frame 7, which is connected to the side frame 4, is fixedly connected to the frame. When the lower end of the unloading platform 3 moves downward, it abuts against the upper end of the limiting frame 7. The limiting frame 7 includes a rectangular frame welded from rods, and the rectangular frame is fixedly connected to the frame.

[0028] The upper end of the limiting frame 7 is fixed with two transverse limiting rods 8, and the unloading platform 3 is constrained in the area between the two transverse limiting rods 8.

[0029] An upwardly expanding guide end 9 is provided between the upper ends of the two transverse limiting rods 8 to guide and ensure that the unloading platform 3 can fall into the area between the two transverse limiting rods 8.

[0030] The head adjustment structure includes a head adjustment telescopic cylinder 11 that is hinged to the frame 1 in parallel, and the telescopic end of the head adjustment telescopic cylinder 11 is hinged to the lower end of the loading platform 2.

[0032] The tail adjustment structure includes a tail adjustment telescopic cylinder 10 that is hinged to the frame 1 in parallel, and the telescopic end of the tail adjustment telescopic cylinder 10 is hinged to the upper end of the unloading platform 3.

[0033] The upper end of the side frame 4 is fixed with a fan-shaped side baffle 6 located outside the loading platform 2 and the unloading platform 3, which blocks the exposed part of the hinged end of the loading platform 2 and the unloading platform 3 to prevent snow from leaking out.

[0034] The upper end of the loading platform 2 and the lower end of the unloading platform 3 are respectively hinged to the hinge shaft 5, and the hinge method is the same as the hinge principle of a hinge.

[0035] The limiting frame 7 includes a rectangular frame welded from rods, which is fixed to the vehicle frame 1.

[0037] The working principle of this device is as follows:

[0038] By changing the traditional conveying platform to a split design, consisting of a loading platform 2 and a unloading platform 3, the height of the lower end of the loading platform 2 can be adjusted through a head adjustment structure, thus adjusting the loading end; the height of the upper end of the unloading platform 3 can be adjusted through a tail adjustment structure. In the working state, the upper end of the unloading platform 3 can be raised to facilitate the transport of snow into the transfer hopper. In the non-working state, the tail adjustment structure lowers the upper end of the unloading platform 3 and supports it on the limit frame 7, thereby reducing the height of the vehicle and improving the vehicle's passability when not in use.
