Description

Technical Field

[0001] The invention relates to the technical field of highway maintenance equipment, and in particular to an ice crushing device for highway maintenance. Background Art

[0002] After a highway is completed and opened to traffic, its quality of use will gradually decline due to the wear and impact of wheels, erosion and weathering by natural forces such as rainstorms, floods, sandstorms, ice and snow, sunlight, and ice melt, as well as human damage and certain defects left over from construction. Therefore, after a highway is completed and opened to traffic, maintenance measures must be taken, and it must be continuously updated and improved. Highway maintenance must repair damaged parts in a timely manner, otherwise it will lead to increased investment in repair projects, shorten the service life of the highway, and cause losses to road users.

[0003] After it snows in winter, the roads are covered with snow. When it first snows, it is easy to melt, but after a long time, it will freeze. People are likely to fall when walking on icy roads, especially in Northeast China where the road icing phenomenon is more serious. In order to facilitate walking, ice crushing equipment is needed to crush the ice.

[0004] In the ice crushing device for highway maintenance, a straight up and down collision head is usually used for crushing. The crushing method is single and the effect is not good. When facing a harder ice layer, it will break into sections of pits. Therefore, when using it, it is necessary to cooperate with manpower to assist in ice crushing. The overall efficiency is low, the investment is high, and it is not conducive to sustainable development. Therefore, the present invention proposes an ice crushing device for highway maintenance to solve the problems existing in the prior art. Summary of the invention

[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0021] At present, for traditional road maintenance ice-breaking devices that use a straight-up and straight-down collision head to break ice, the straight-up and straight-down collision head only breaks the ice layer by vertical impact force, and does not use other shear or tensile forces, resulting in low energy utilization efficiency. At the same time, when the ice layer is thicker or harder, the collision head often cannot effectively break the ice, but only forms irregular potholes on the surface. Further impact force to break the ice requires a larger power output, which has high requirements on equipment and energy consumption. At the same time, the operation speed is slow, affecting the overall efficiency.

[0022] Therefore, according to Figure 1-Figure 4As shown, this embodiment proposes an ice crushing device for highway maintenance, including a connecting seat 1, on which a salt spreading assembly is installed, the salt spreading assembly includes a first storage chamber 16, a feeding chamber 17 is provided below the first storage chamber 16, and is communicated with the feeding chamber 17, and the first storage chamber 16 and the feeding chamber 17 are both arranged in the connecting seat 1, and a feeding auger 18 is installed inside the feeding chamber 17, and the feeding auger 18 has a driving motor for driving it to rotate, and the driving motor is located outside the connecting seat 1 and is fixedly connected to the connecting seat 1 through a bracket. A salt spreading port 19 is provided at the lower end of the connecting seat 1, and the salt spreading port 19 is provided with a plurality of groups, and the salt spreading port 19 is communicated with the feeding chamber 17. When working, the inner cavity of the first storage chamber 16 is filled with salt to be spread by the staff, and during the movement of the device, the feeding auger 18 is started, and the salt is transported to the salt spreading port 19, and then discharged from the salt spreading port 19, and then falls on the road surface. Furthermore, in order to control the amount of salt spread, an electric control valve may be installed on the salt spreading opening 19 to control the amount of salt spread by adjusting the size of the opening.

[0023] A second storage chamber 21 is provided inside the connection base 1. The upper ends of the second storage chamber 21 and the first storage chamber 16 are both connected to the outside and are provided with a dust cover 22. The second storage chamber 21 serves as a storage space, providing a space for storing salt.

[0024] An extension portion 2 is provided on the connecting seat 1, and the extension portion 2 and the connecting seat 1 are designed as an integral whole. A fixing plate 3 is installed on one side of the connecting seat 1, and the fixing plate 3 is located below the extension portion 2. A horizontal ice crushing assembly is installed on the fixing plate 3, and the horizontal ice crushing assembly includes a connecting shaft 13, and the connecting shaft 13 is provided with several groups. In this embodiment, the connecting shaft 13 is symmetrically provided with two groups, and the connecting shaft 13 is connected to the fixing plate 3 through a bearing and driven by a second motor 14. The second motor 14 is located above the fixing plate 3 and is fixedly connected to the fixing plate 3 through a bracket, thereby providing power to the connecting shaft 13 through the second motor 14 to ensure continuous rotation of the shaft, and a connecting disk 14 is installed at the lower end of the connecting shaft 13, and an ice crushing blade 15 is installed on the outer side of the connecting disk 14, and the ice crushing blade 15 is inclined to help the ice layer to generate shear and cutting force, and the ice crushing blade 15 is evenly provided with several groups, and then the connecting disk 14 transmits power to the ice crushing blade 15 through rotation to ensure that the blade 15 cuts the ice layer on the road surface. As for the inclination angle of the ice-breaking blade 15, when it is 15° to 30°, it has better adaptability to thinner ice layers (<5cm), reducing damage to the road surface. For thicker ice layers (greater than 5cm), the inclination angle is increased to 30° to 45°, generating greater shear force through the inclination angle, thereby improving ice-breaking efficiency.

[0025] An outer protective cover 4 is provided on one side of the extension part 2 to protect the shear blade 8 and the main shaft 5 from the influence of the external environment. The outer protective cover 4 is hinged to the extension part 2. The main shaft 5 is installed on the inner side of the outer protective cover 4 through a bearing, and the main shaft 5 is driven by the first motor 6. The outer side of the main shaft 5 is sleeved with a mounting tube 7, and the mounting tube 7 is connected to the main shaft 5 through a plurality of groups of support rods. The outer side of the mounting tube 7 is distributed with shear blades 8, and the shear blades 8 are provided with a plurality of groups to achieve comprehensive shearing and processing of the ice layer in a uniformly distributed manner. The shear blades 8 are arranged in an inclined manner, and the angle selection method is the same as the ice-crushing blade 15. Then, when working, the first motor 6 drives the main shaft 5 to rotate, and at the same time drives the mounting tube 7 and the shear blade 8 to rotate at a high speed. The shear blade 8 acts on the ice layer with a rotating shear force through its inclined design, cuts into and crushes the ice cubes, and the lateral force generated by the inclined angle can also push the crushed ice cubes away from the equipment, which is convenient for subsequent processing.

[0026] The fixing plate 3 is connected to the outer protective cover 4 through a spring shock absorber 20. Both ends of the spring shock absorber 20 are hinged to the fixing plate 3 and the outer protective cover 4, and the spring shock absorber 20 is arranged in an inclined manner. The spring shock absorber 20 is arranged to connect to the outer protective cover 4 to enhance the overall stability of the device. Furthermore, when the device is working, an external traction vehicle is required to push it, that is, the device is located in front of the external traction vehicle, and in the actual ice crushing process, external personnel are required to take care of it to prevent pedestrians or other vehicles from entering the working range. Furthermore, when the device is working, the connecting seat 1 needs to be fixedly connected to the traction component of the external traction vehicle to ensure the stability of the connecting seat 1. The lower ends of the connecting seat 1 and the assembly shell 9 are both equipped with support wheels 24, and the support wheels 24 are provided with several groups, and then cooperate with the support wheels 24 and the spring shock absorber 20 to form a whole with the traction vehicle. Then in this process, the support wheel 24 on the assembly housing 9 will first contact the ice surface to determine the initial working height of the device. At this time, the shear blade 8 and the ice crushing blade 15 will also contact the ice surface and extend a certain distance, which usually does not exceed 70% to 90% of the thickness of the ice layer to protect the road surface from damage.

[0027] In another embodiment, the assembly housing 9 is mounted with the support wheel 24 via an electric hydraulic rod, that is, the position of the support wheel 24 can be adjusted, thereby achieving adjustment of the height of the support wheel 24 to adapt to different ice thicknesses and ground conditions.

[0028] An assembly shell 9 is installed at one end of the outer protective cover 4, and an electric heating component is installed on the assembly shell 9, the electric heating component includes a resistance wire heating plate 10, a wireless controller 11 is installed on the inner side of the assembly shell 9, the resistance wire heating plate 10 is located below the assembly shell 9 and is fixedly connected to the assembly shell 9, a partition is installed on the inner side of the assembly shell 9, and a battery pack 12 is installed on the partition, and the battery pack 12 is electrically connected to the resistance wire heating plate 10 through the wireless controller 11. Further, a solar panel 23 is installed above the outer protective cover 4 through a bracket, and the solar panel 23 is electrically connected to the battery pack 12. When working, the solar panel 23 absorbs solar energy and converts it into electrical energy, and is electrically connected to the battery pack 12 through a bracket to store excess energy in the battery. The wireless controller 11 (which has a wireless connection function so that external personnel can use computer equipment for wireless connection) supplies power to the resistance wire heating plate 10 through the battery pack and controls the power and working time of the heating plate according to instructions. When the resistance wire heating plate 10 is working, it transfers heat energy to the surface of the ice layer to soften or melt the ice layer, creating conditions for the ice breaking operation of the shear blade 8 and the ice crushing blade 15. In this way, the device provides auxiliary power through solar energy and reduces dependence on external energy.

[0029] In summary, the present invention first melts the ice layer by heat transfer to facilitate subsequent mechanical ice breaking, and then uses shear force to break the ice to replace the vertical impact ice breaking method, and then uses horizontal destructive force to crush the broken ice cubes, and finally spreads salt to quickly melt the remaining ice cubes and prevent new ice from forming. During the whole process, the present invention integrates four functions: heat pretreatment, vertical rotating shear blade, horizontal rotating blade crushing treatment and salt spreading and melting, which effectively solves the problem of low efficiency of the single mechanical method in the existing ice breaking device. The salt is not sprinkled at the beginning, but at the end, because the effect of salt on ice is mainly to reduce the melting point of ice, so that the ice melts at a lower temperature, but salt can only act on the ice surface with a small amount of water, and the effect on the completely dry ice surface is limited. Therefore, the present device can destroy the dry state of ice through heat pretreatment and subsequent ice crushing to improve the effect after salting.
