Description

Technical Field

[0001] The utility model relates to the technical field of road snow removal equipment, in particular to a shovel truck for convenient road snow removal. Background Art

[0002] When it snows, the snow on the road will affect the grip of the tires, increase the braking distance of the vehicle, and even cause the vehicle to lose control, increasing the probability of a traffic accident. Therefore, when it snows, the snow on the road needs to be cleared in time.

[0003] In the prior art, a shovel blade is generally installed in front of a forklift or other vehicle, and the blade contacts the ground. The blade moves forward under the drive of the vehicle to remove the snow on the road. Forklifts all use steel blades to shovel snow. Since the snow is compacted during the repeated rolling of the vehicle, it will also adhere to the road surface. Therefore, the blade needs to contact the ground and apply a certain pressure to remove the snow and ice. The friction between the blade and the road will reduce the service life of the blade. Therefore, high-strength alloy steel is generally used to make the blade of the blade to extend the service life of the blade, but the high-strength blade will damage the ground.

[0032] The moving device 1 includes a chassis 11, with tracks 12 on both sides of the chassis 11, the tracks 12 are used to drive the chassis 11 forward, and the front side of the chassis 11 is connected to a blade assembly 2 through a mounting frame, and the mounting frame is used to drive the blade assembly 2 to rotate up, down, left, and right.

[0033] A cab 13 is provided in the middle of the top surface of the chassis 11, and the cab 13 is used for an operator to sit in and control the forward direction of the crawler track 12. The crawler track 12 adopts a working crawler drive device.

[0034] The mounting frame includes a connecting frame 14, which is welded to the front center of the chassis 11. An upper and lower rotating frame 15 is rotatably mounted on the front center of the connecting frame 14 through a rotating shaft, and a left and right rotating frame 16 is rotatably mounted on the front side of the upper and lower rotating frame 15 through a rotating shaft.

[0035] A lifting cylinder 17 is rotatably installed on the top surface of the upper and lower rotating frame 15, and the rear end of the cylinder body of the lifting cylinder 17 is rotatably connected to the front side of the chassis 11. A deflection cylinder 18 is rotatably installed on the left and right sides of the upper and lower rotating frame 15, and the rear end of the cylinder body of the deflection cylinder 18 is rotatably connected to the scraper assembly 2.

[0036] The blade assembly 2 includes a main blade 21 and an auxiliary blade 23. The auxiliary blade 23 is installed on the front side of the main blade 21 through the adjustment assembly 3. An ice-breaking device is provided at the bottom of the back of the auxiliary blade 23 to break up the compacted snow on the ground.

[0037] The left and right rotating frame 16 is welded and installed in the middle of the back of the main blade 21, and the rear end of the cylinder body of the deflection oil cylinder 18 is rotatably connected to the back of the main blade 21. By controlling the piston rod of the lifting oil cylinder 17 to extend or retract, the upper and lower rotating frame 15 can be driven to rotate up and down, thereby driving the left and right rotating frame 16 to rotate up and down, and then driving the main blade 21 to rotate up and down. By controlling the piston rod of the deflection oil cylinder 18 to extend or retract, the main blade 21 and the left and right rotating frame 16 can be driven to rotate left and right.

The lowest point of the auxiliary cutter disc 24 is higher than the lowest point of the main cutter disc 22.

[0039] The auxiliary blade disc 24 is used to remove the uncompacted part of the upper layer of snow on the road. The main blade disc 22 is used to remove the broken compacted snow blocks.

[0040] The ice breaking device includes a plurality of crushing wheels 25, and a plurality of protrusions are evenly arranged on the surface of the crushing wheels 25. The lowest point of the crushing wheels 25 is located at the same horizontal plane as the lowest point of the main blade 22. A crushing shaft 26 is inserted through the center of the crushing wheel 25, and the crushing shaft 26 is rotatably mounted on the back of the auxiliary blade 23 through a crushing shaft bracket 27.

[0041] The crushing shaft support 27 is fixedly connected to the auxiliary blade 23 by bolts. The crushing wheel 25 is a solid metal wheel.

[0042] When the crawler 12 drives the chassis 11 forward, it can drive the blade assembly 2 to move through the mounting frame. When the main blade disc 22 and the crushing wheel 25 are in contact with the ground at the same time, the crushing wheel 25 rolls forward and can use its own weight and surface protrusions to crush the compacted snow, so that the snow or ice is broken into small pieces and separated from the ground. Then the main blade disc 22 shovels the snow or ice.

[0043] The adjustment assembly 3 includes a connecting rod 33, which is rotatably connected to the ice breaking device and the main blade 21. The upper part of the connecting rod 33 is connected to the auxiliary blade 23 through the auxiliary blade adjustment cylinder 34, and the lower part of the connecting rod 33 is connected to the main blade 21 through the crushing wheel adjustment cylinder 35. The head of the connecting rod 33 is rotatably connected to both ends of the crushing shaft 26.

[0048] By controlling the piston rod of the auxiliary blade adjusting cylinder 34 to extend or retract, the auxiliary blade 23 can be driven to rotate around the crushing shaft 26, thereby driving the auxiliary cutter disc 24 to rotate around the crushing shaft 26, thereby controlling the height difference between the lowest point of the auxiliary cutter disc 24 and the lowest point of the crushing wheel 25.

[0049] When the operator of this embodiment uses the device, he controls the piston rod of the lifting cylinder 17 to extend and drives the upper and lower rotating frames 15 to rotate downward until the lowest point of the main cutter head 22 touches the ground.

[0050] Keep the piston rod of the auxiliary blade adjusting cylinder 34 stationary, control the piston rod of the crushing wheel adjusting cylinder 35 to retract, drive the tail of the connecting rod 33 to rotate relative to the main rotating frame 31, thereby driving the crushing shaft 26 and the auxiliary blade 23 to lower until the lowest point of the crushing wheel 25 is controlled to touch the ground.

[0051] Then, keep the piston rod of the crushing wheel adjusting cylinder 35 stationary, control the piston rod of the auxiliary knife adjusting cylinder 34 to extend or retract, drive the auxiliary shovel 23 to rotate around the crushing shaft 26, thereby driving the auxiliary knife disc 24 to rotate around the crushing shaft 26, and control the lowest point of the auxiliary knife disc 24 to be inserted into the snow but not in contact with the ground.

[0052] The action device 1 drives the blade assembly 2 to move forward, the auxiliary blade disc 24 removes the upper floating snow, and the crushing wheel 25 rolls forward, and can use its own weight and surface protrusions to break the compacted snow, so that the snow or ice is broken into small pieces and separated from the ground. Then the main blade disc 22 removes the snow or ice.

[0053] The piston rod of the deflection oil cylinder 18 is controlled to extend or retract, driving the main blade 21 and the left and right rotating frame 16 to rotate left and right. The snow being shoveled can be controlled to move to the left or right.
