Description

Technical Field

[0001] This invention relates to an ice-breaking spike for clearing ice and snow from roads in winter, and also to an ice-breaking wheel on which such ice-breaking spikes are installed. Background Technology

[0002] In winter, icy and snowy roads can seriously affect driving safety. This is especially true in northern winters, where icy and snowy roads are more common. To clear ice and snow from roads, especially ice and snow repeatedly crushed by vehicle wheels, many specialized devices have been developed. These devices generally include ice-breaking wheels that come into direct contact with the road surface. These ice-breaking wheels are installed at the front of the device and are towed and operated by a motor vehicle. The ice-breaking wheels roll, crush, and peel away the ice and snow from the road surface.

[0003] like Figure 1 As shown, Figure 1 The paper describes an ice-breaking wheel with numerous ice-breaking teeth evenly distributed on its surface. These teeth are parallel to the wheel's axis, with their tips pointing outwards from the rim. During operation, the ice-breaking wheel rolls continuously forward, the tooth tips penetrating the ice and snow layer, breaking and peeling it away, resulting in high efficiency in ice and snow removal. However, because the ice-breaking teeth are parallel to the wheel's axis and contact the road surface simultaneously along its entire length, uneven surfaces can easily damage the road surface and the tooth tips.

[0004] like Figure 2 As shown, Figure 2 An ice-breaking and snow-removing device with ice-breaking teeth obliquely arranged on the surface of an ice-breaking wheel is presented. The advantage of this structure is that the ice-breaking teeth make continuous, localized point contact with the road surface, rather than simultaneous contact along the entire length, thus reducing the requirements on the road surface and extending its service life. However, with the oblique arrangement, in addition to radial and circumferential forces, the ice and snow exert an axial force on the ice-breaking teeth during snow removal. This axial force makes the ice-breaking wheel difficult to control.

[0005] like Figure 3 As shown, Figure 3 A herringbone tooth ice-breaking wheel is proposed. The axial force is offset by the symmetrical helical tooth arrangement, which solves the problem of the difficulty in controlling the helical tooth ice breaking. However, the ice and snow layer between the two herringbone teeth is connected into a long strip. The bonding area between the ice and snow and between the ice and snow and the ground is large, making it difficult to separate and adhere to the ground. Summary of the Invention

[0006] The purpose of this invention is to provide a cross-shaped ice-breaking spike for breaking ice and removing snow, and an ice-breaking wheel on which the ice-breaking spike is installed. It can cut large areas of ice and snow into smaller areas during ice and snow removal, reducing the adhesion and sticking of large areas of ice and snow to the ground.

[0007] The cross-shaped ice breaking spike capable of breaking ice and removing snow comprises a spike base and four spike plates, the four spike plates are fixed on the side vertical surfaces of the spike base to form a cross-shaped structure, and the upper top surface of each spike plate is a circular arc gradually decreasing from the inner side end to the outer side end of the spike base.

[0008] The ice breaking wheel provided with the cross-shaped ice breaking spike comprises an ice breaking wheel body, and further comprises a plurality of cross-shaped ice breaking spikes, the cross-shaped ice breaking spikes are uniformly arranged on the outer circumferential surface of the ice breaking wheel body, and the bottom of the spike base of the cross-shaped ice breaking spike is fixed on the outer circumferential surface of the ice breaking wheel body.

[0009] The breaking principle is as follows: the cross-shaped ice breaking spike is designed as a cross-shaped spike plate structure, the top of the spike plate is designed as a circular arc, the ice breaking wheel rolls to contact the ice and snow on the road surface, so that the spike plate enters the ice and snow layer under pressure in the ice breaking process, and the ice and snow layer is extruded to the two sides of the spike plate, so that the ice and snow in the ice and snow layer is broken. A plurality of ice breaking spikes are installed on the ice breaking wheel, and the ice breaking spikes continuously penetrate into the ice and snow layer when the ice breaking wheel works to roll on the ice and snow layer, so that the ice and snow layer is continuously broken and peeled off. Due to the spike plate provided in the application, the long strip-shaped ice and snow is cut into small pieces, and the bonding force between the ice and snow and between the ice and snow and the ground is broken. Compared with the prior art, the outer arc surface of the spike plate of the ice breaking spike in the application contacts the ice and snow more reasonably. BRIEF DESCRIPTION OF DRAWINGS
