Description

Technical Field

[0001] The utility model relates to a snow removal vehicle, in particular to a multifunctional ice-breaking and snow-removing vehicle. Background Art

[0002] At present, most domestic snow removal equipment relies on modified dump trucks, and its functions are limited to pushing and sweeping snow and spreading snow-melting agents. There is a lack of operating vehicles with multiple snow removal functions integrated into one. Conventional pushing and sweeping operations cannot clear the ice layer on the road, and the solid spreading snow-melting effect is slow. The crushing rollers on the market rely on their own weight to crush the ice layer, and the crushed ice cannot be cleared in time. The remaining ice and snow are crushed again and become compacted snow, which cannot be cleaned thoroughly. There are deficiencies in both functionality and professionalism, and they cannot meet the complex working conditions of special emergency snow removal. This patented snowplow can simultaneously spread solid and liquid snow-melting agents evenly on the road surface to prevent the road from icing and ensure the safety of road vehicles. The front hanging mechanism can be loaded with a snow shovel or snow brush to clear the snow on the road to ensure smooth roads. The central spiral cutting ice breaker breaks the hard ice and snow, and the rear ice scraper and spiral side discharge function discharge the crushed ice. The rear blowing device cleans the remaining residual ice and snow for a second time. Utility Model Content

[0039] The front spray device includes: a front spray duckbill 4-6 installed on the distribution pipe, and an air control valve 4-7 is provided on the distribution pipe, and the air control valve 4-7 is connected to the chassis air bag.

[0040] like Figure 4 As shown, the ice-breaking device 5 includes: an ice-breaking motor 5-1, an auger, and an ice scraper 5-3. The ice-breaking device 5 is driven by the ice-breaking motor 5-1 to rotate the auger, and the auger is provided with an ice-breaking blade 5-2 to break the ice surface. At the same time, the auger has a side discharge function when rotating, and discharges the accumulated snow and ice to the outside of the vehicle. The ice scraper 5-3 is arranged at the rear side of the auger to collect the crushed ice residue after breaking the ice.

[0041] The ice breaking device 5 is driven by the high-torque ice breaking motors 5-1 on both sides to drive the gears to rotate, and the rotation is realized by chain transmission to the main shaft of the ice breaker. The auger blades are of auger type and are equipped with ice breaking blades 5-2. The ice surface is broken by high-speed rotation. After breaking, the ice cubes are collected by the ice scraper 5-3 on the rear side. Because the auger structure has a side discharge function, the crushed ice can be discharged to the outside.

[0042] The lifting device 9 includes: a lifting cylinder 9-12-6, a lifting frame 9-2, a track 9-3, a roller group 9-4, and an adjusting device 9-5. The upper end of the front hanging frame 2 is connected to the chassis assembly 1, and the ice-breaking device 5 and the rear purge device 6 are slidably installed on the front hanging frame 2 through the track 9-3 and the roller group 9-4. The upper end of the lifting cylinder 9-12-6 is connected to the lifting frame, and the lower end is connected to the ice-breaking device 5 or the rear purge device 6 through the adjusting device 9-5; the lifting frame 9-2 is driven to rise and fall by the extension and contraction of the lifting cylinder 9-12-6, the roller group 9-4 is connected to the lifting frame 9-2 and rolls in the track 9-3 as the lifting frame 9-2 rises and falls. The lifting frame 9-2 is welded with a limit block to prevent the track 9-3 from deflecting during the operation of the machine. The adjusting device 9-5 can automatically adjust the difference caused by the uneven road surface during the ice-breaking process through the compression of the spring 9-5-4; the roller group 9-4 is equipped with rolling bearings to ensure smooth rolling.

[0043] like Figure 5 As shown, the adjusting device 9-5 includes: a hinged plate 9-5-1, a guide sleeve 9-5-2, a guide rod 9-5-3, a spring 9-5-4, and a limit block 9-5-5. The center of the hinged plate 9-5-1 is hinged at the lower end of the lifting cylinder 9-12-6, and the guide sleeve 9-5-2 is symmetrically installed on both sides of the hinged plate 9-5-1. The guide rod 9-5-3 is slidably installed in the guide sleeve 9-5-2, and its lower end is fixed on the ice-breaking device 5 or the rear-blowing device 6. The spring 9-5-4 is arranged on the guide rod 9-5-3 between the guide sleeve 9-5-2 and the ice-breaking device 5 or the rear-blowing device 6. The limit block 9-5-5 is installed on the end of the guide rod 9-5-3 extending above the guide sleeve 9-5-2. Through the adjusting device 9-5, when the ice-breaking device 5 or the rear-blowing device 6 encounters an obstacle during operation, the spring 9-5-4 is compressed and rolled over the obstacle.

[0044] When the ice-breaking device 5 or the rear purge device 6 encounters an obstacle, the adjusting device 9-5 will move forward and upward after encountering resistance, thereby compressing the spring 9-5-4 to achieve overcoming the obstacle. After overcoming the obstacle, the spring 9-5-4 returns to its original length, thereby pushing the ice-breaking device 5 and the rear purge device 6 to re-contact the ice surface and reset the work.

[0045] like Figure 4As shown, the rear blowing device 6 is also connected to the chassis assembly 1 through the lifting device 9. The lifting device 9 controls the lifting and lowering of the rear blowing device 6 and the rotation of the roller brush of the driving motor. A large-volume snow blower is configured to blow the swept snow to the outside, and perform secondary cleaning of the ice and snow remaining after breaking the ice. Specifically: the rear blowing device 6 is composed of a snow sweeping brush and a fan assembly 6-2. The rotation of the sweeping brush is driven by the rear brush motor 6-1 on both sides directly connected to the snow brush, and the lifting is achieved by the lifting device 9. The rear large-volume fan is driven by the hydraulic pump to rotate and drive the fan to work. The combination of the blowing devices can blow the swept snow to the outside, and perform secondary cleaning of the ice and snow remaining after breaking the ice. The rear brush motor 6-1 is a hydraulic motor 7-2.

[0046] like Figure 4 As shown, the box assembly 7 is mainly divided into two parts: a liquid spreading tank body and a solid spreader. The liquid spreading tank body is a stainless steel liquid tank with a corrugated shape to ensure the strength of the tank body. A wave-breaking plate is provided in the tank body to reduce the impact of liquid fluctuations on the tank body. A small-pore filter is provided at the water outlet to filter undissolved particles to prevent clogging of the nozzle. A low-level alarm system is provided in the tank to ensure effective operation.

[0047] The solid spreader adopts an integrated spreader. The spreader's integrated inverted V-shaped silo design facilitates the sliding of solid materials. The silo is equipped with a screen to filter the snow-melting agent. The spreading motor 7-7 drives the herringbone rubber belt to realize conveying and discharging. The spreading motor 7-7 is a hydraulic motor 7-2.

[0048] The electrical system is installed on the inner side of the cover assembly 8.

[0049] The cover assembly 8 consists of two side guards and rolling doors. The two side guards are installed on both sides of the spreader to protect the control components inside the guards. There are 6 rolling doors on the two side guards for debugging and maintenance.

[0050] The oil pumps in the hydraulic system are all fixed-displacement pumps. Each power part controls the pipeline pressure separately to achieve different snow-clearing actions. The action is achieved by turning the power on and off of the hydraulic solenoid valve. All the cylinders of the actions are equipped with two-way throttle valves. Mechanical speed regulation can ensure stable and impact-free action.

[0051] The front-mounted snow-clearing function is to pull the lifting handle 2-1 in the front bracket 2 of the vehicle, pull it up and hook it on the lock plate 2-2, insert the connecting end of the front snow-clearing device into the driving seat 2-3, pull down the lifting handle 2-1 to lock the connecting end, and connect the upper end to the hanging beam 2-5 through the chain 2-4. Adjust the length of the chain 2-4 to make the snow brush horizontal; connect the front snow-clearing device quick connector with the reserved quick connector on the vehicle, and the power take-off mechanism 3 transmits the power output of the power pump to the snow brush motor in the front snow-clearing device through the hydraulic pipeline to drive the snow brush to rotate, and lift the oil cylinder 9-12-6 to realize the lifting and lowering of the snow brush, and swing the oil cylinder 2-7 to realize the left and right swing of the snow brush. During operation, the snow brush is turned on and floats to make the brush blade fully contact with the ground, and the snow brush is swung to the right to realize snow clearing operation.

[0052] The front-mounted snow-clearing function adopts the front-mounted snow-clearing function installation method, and the front snow-clearing device is replaced with a snow shovel. However, the snow shovel does not need to be automatic. It only needs to lift the oil cylinders 9-12-6 to realize the lifting and lowering of the snow shovel, and swing the oil cylinders 2-7 to realize the left and right swing of the snow shovel.

[0053] For the liquid spreading function, turn on the water pump button, and the water pump 4-3 with the hydraulic motor 7-2 will start working. The water pump draws liquid from the liquid spreading tank and transfers it through the pipeline to the front nozzle and the rear spreading device 4-1 for spraying operation; the three-way ball valve 4-4 is connected to the AB port to open the liquid spreading channel, and the AC port can be connected to realize the self-priming function. An external water hose can be connected at the C port to suck the external liquid into the tank through the water pump, and the greening interface D can be opened to connect an external fire hose to realize the greening watering function; the three-way ball valve 4-4BC port is connected or the water release valve 4-5F port is opened to realize the water release operation; the duckbills on both sides of the front device are each equipped with a pneumatic disconnect valve for single-side and double-side spraying, and the rear spreading device 4-1 is respectively provided with three spraying sections at the left, right and middle. Each section is equipped with a universal nozzle to realize the combined spraying of each section through the air valve.

[0054] Turn on the spreading function, the hydraulic motor 7-2 in the solid spreader drives the belt reducer 7-3 to rotate, the output end of the belt reducer 7-3 is connected to the belt conveyor roller 7-4, driving the conveyor roller to rotate to realize the transmission of the snowmelt material. After the solid spreader is lowered, the snowmelt material enters the solid spreader, and the lower end spreading disc 7-6 is driven to rotate by the hydraulic motor 7-2. After the snowmelt material enters the spreading disc 7-6, it is thrown out to realize spreading. The spreading chute 7-5 is provided with an adjustment function, which can realize the spreading height from the ground through different mounting hole positions, thereby adapting to the spreading on different working roads.

[0055] The hydraulic motor 7 - 2 and the oil pump are both connected to the power take-off mechanism 3 , so that all power comes from the chassis 1 without the need for an additional auxiliary engine, thereby reducing costs.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
