Description

Technical Field

[0001] The present invention belongs to environmental protection equipment, and mainly relates to an ice clearing roller suitable for removing thick ice and snow layers on the road surface. Background Art

[0002] In order to solve and remove the ice and snow layers on the road surface frozen after rain, snow, including thin ice layers, extremely thick ice and snow layers, as well as hard ice lumps formed by automobile exhaust and semi-melted and semi-frozen black ice composed of ice and water, namely the so-called "stubborn ice", the applicant has developed a "combined road surface ice crushing roller of saw blade hob and gear hob" that has obtained a patent right. Its structure realizes the removal operation of "stubborn ice" including thin ice layers. However, since this roller adopts an external input rotary power-driven gear hob assembly to actively rotate and strike the operation structure, there are not only defects such as high consumption of external input rotary power, high operation cost, complex structure, easy damage to the road surface, especially poor effect of removing thick ice and snow layers, but also problems such as large vibration and noise of the machine during operation, many use failures, and short service life.

[0003] In recent years, the applicant has also developed a "combined road surface ice clearing roller of saw blade hob and rolling hob" without external input rotary power drive and has submitted a patent application. It is found in the test operation that the rolling hob structure has technical problems such as poor removal operation ability for super-thick compacted ice and snow layers above 40 mm, poor removal effect, low operation efficiency, and large traction power consumption, which need to be overcome and solved. Summary of the Invention

[0004] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, and in combination with the actual needs for the removal operation of super-thick compacted ice and snow layers on the road surface, research and design a combined road surface ice clearing roller of a spiral thorn roller assembly and a saw blade hob assembly, so as to achieve the purpose of meeting and adapting to the use of super-thick compacted ice and snow layer removal operation, strong operation applicability, good removal effect, high operation efficiency, small damage to the road surface, and less power consumption.

[0005] The purpose of the present invention is achieved as follows: A plurality of circular rod seats are fixedly installed on the roller shaft in sequence from left to right. On the roller shaft, between adjacent circular rod seats, a saw blade hob assembly is axially and radially positioned and circumferentially rotatably sleeved. On the outer wall plate of each circular rod seat ring, a plurality of needle-shaped tooth rods are fixedly installed in multiple spiral directions respectively to form a spiral thorn roller assembly. The multiple needle-shaped tooth rods on the multiple spiral thorn roller assemblies are arranged in an overall multi-head continuous spiral line shape; the diameter size Φ1 of the saw blade hob assembly ≥ the diameter size Φ2 of the spiral thorn roller assembly. Thus, a combined road surface ice clearing roller of a spiral thorn roller assembly and a saw blade hob assembly is formed.

[0006] The invention adopts a coaxial and spaced installation structure of a spiral licker-in roller assembly and a saw blade cutter assembly that are driven to rotate without external power. During operation, the thick ice and snow layer is longitudinally sawed and divided by the saw blade cutter assembly, and the strip-shaped ice and snow layer is separated and crushed by the spiral licker-in roller assembly through pricking and plucking. The speed difference of the follow-up circular rotation between the saw blade cutter assembly and the spiral licker-in roller assembly is fully utilized and exerted, so as to quickly and high-quality complete the removal operation of various ice and snow layers of different thicknesses and hardnesses and stubborn ice, especially the ultra-thick compacted ice and snow layer (about 60 mm) on the road surface. The invention has the characteristics of novel, unique, simple, reasonable structure, strong applicability, wide application range, good operation quality, high efficiency, low traction power consumption, low operation cost, low noise and vibration, stable operation, and no damage to the road surface. In particular, it can operate on the ultra-thick compacted ice and snow layer of about 60 mm with high quality and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following is a detailed description of the implementation scheme of the invention in conjunction with the accompanying drawings. A road ice-clearing roller composed of a spiral licker-in roller assembly and a saw blade cutter assembly comprises a shield-type roller frame 1 and a saw blade cutter assembly 2, a roller shaft 5 is rotatably supported and installed on the inner side of the lower end of the shield-type roller frame 1, a plurality of annular rod seats 4 are fixedly mounted on the roller shaft 5 from left to right, a saw blade cutter assembly 2 is axially and radially positioned and circumferentially rotatably mounted on the roller shaft 5 at the position between adjacent annular rod seats 4, a plurality of needle-like tooth rods 3 are fixedly mounted on the outer wall plate of each annular rod seat 4 in a plurality of spiral lines, forming a spiral licker-in roller assembly, and the plurality of needle-like tooth rods 3 on the plurality of spiral licker-in roller assemblies are arranged in a multi-head continuous spiral line as a whole; the diameter size Φ1 of the saw blade cutter assembly 2 is ≥ the diameter size Φ2 of the spiral licker-in roller assembly.

[0014] During operation, the ice cleaning roller is integrally assembled on the road surface ice and snow removal equipment by using the shielded roller rack 1, and moves forward driven by a power locomotive. Relying on the weight of the ice cleaning roller and the downward pressure of the hydraulic suspension system of the power locomotive, the spiral thorn roller assembly and the saw blade hob assembly 2 are brought into contact with and pressed against the road surface ice and snow layer. The saw blade hob assembly 2 cuts into the compacted ice and snow layer and is in a slightly contacting state with the road surface. The needle-shaped tooth bars 3 on the spiral thorn roller assembly are inserted into the compacted ice and snow layer. Under the action of the resistance of the ice and snow layer, the saw blade hob assembly 2 performs longitudinal rolling cutting or translational sliding cutting on the ice and snow layer, dividing the ice and snow layer into strip-shaped bands. Synchronously, the needle-shaped tooth bars 3 on the rotating spiral thorn roller assembly sequentially complete the operations of poking, crushing and separating from the road surface for the strip-shaped ice and snow layer.

[0015] During the operation process, since the rolling resistance of the compacted ice and snow layer to the saw blade hob assembly 2 is less than that to the needle-shaped tooth bars 3 on the spiral thorn roller assembly, the rotation speed of the saw blade hob assembly 2 is lower than that of the needle-shaped tooth bars 3, generating a rotational speed difference, and forming a disturbing, kneading and scissor action on the ice and snow layer among each other, ensuring the quality, effect and efficiency of the cleaning operation. The needle-shaped tooth bars 3 configured in a multi-head spiral line are successively inserted into the compacted road surface ice and snow layer, reducing the reverse acting force of the ice and snow layer on the ice cleaning roller, ensuring the stable operation of the equipment and reducing vibration.
