Abstract

The utility model relates to an implement which uses the pressing, the vibrating and the digging of a plane iron to crush and separate a compacted and frozen ice and snow layer. The main work part of the utility model is that a batch of straight or spiral rolling cylinders of the plane iron are fixed on the surface of a cylinder, and a vibration stimulating source composed of a rotary eccentric shaft is arranged in the rolling cylinder. The rolling cylinder vibrates in high frequency and small magnitude in the process of rolling, the rolling cylinder is driven by a walking motor and is connected with a machine frame through a shock absorber, and the machine frame is supported on an adjustable depth limit supporting wheel; the implement and a self-propelled chassis with power can form a self-propelled ice breaker and can also form a passive ice breaker which is pulled by a tractor. The utility model is a machine with high efficiency and good ice and snow breaking performance because the functions like the pressing, the vibration and the digging are designed for the weakness of the snow and ice layer which is material with fragility and vibration intolerance when the snow and ice layer moves away from the ground.

Description

" press, shake, dig " broken freezer

The utility model relates to the machinery of the ice and snow layer that is compacted on a kind of broken road surface and freezes.

Known broken freezer generally has rotation milling formula or reciprocal impact type at present, or the rotary hammer impact type.The basic point of their work all is to be to have the material of certain degree of hardness and intensity to set out with ice and snow layer, and it is broken to adopt similar milling metal mode; Though impact type has been utilized the not impact-resistant characteristic of fragile material, it impacts the fragmentation of the ice and snow layer that must finish FX each time and peels off, and therefore back and forth impact or rotary impact all are the die-cut formulas of low frequency.Though milling and the die-cut power that all needs bigger driving operating mechanism, and injustice is arranged slightly when the road surface, not to have hindered the road surface, be exactly ice and snow layer is not exclusively broken.

The purpose of this utility model provides a kind of high crushing efficiency that has, and the ice and snow layer of the different situations of uneven road surface is still had the broken freezer of the snow performance that better opens ice.

The realization of the utility model purpose is to come down to the great material of a kind of fragility according to simple ice and snow layer, its more difficult fragmentation be because it the road surface is arranged is support, if apply the vibration of the little amplitude of certain intensity and frequency, it will be easy to be shaken such basic point that looses.Therefore the utility model is a kind ofly to roll on the road surface, and the garden is furnished with the cylinder of a collection of plate shaped or spiral helicine planing tool on week; Cylinder has suitable weight and an exciting source is arranged, and exciting source can be the eccentric shaft structure of a rotation, also can be the double-eccentric shaft structure that can produce the incorgruous rotation of vertical double vibrations, also can be the structure of double-eccentric shaft in the same way that can produce alternate torque.The broken ice and snow process of the utility model is the weight with cylinder, make the planing tool of its garden on week be pressed into ice and snow layer--" pressure ", cylinder is in high frequency and slightly vibrates when rolling, the crack in the ice and snow layer is developed rapidly, and the ice and snow layer in the corresponding certain limit is shaken diffusing--and " shaking "; And then because the track of planing tool blade has the action of " plane " that ice and snow layer is further dug pine-" plane " after entering ice and snow layer.Can also make " pressures " " plane " afterwards loose ice and snow side that axially collects in cylinder of " shaking " if use the helical form planing tool along cylinder.

The cylinder that is provided with planing tool that the vibration of constant weight is arranged is a kind of fragility that makes full use of ice and snow layer, and acquisition efficiently and is well opened ice and avenged the snow facility that open ice of performance.

The utility model is described in further detail below in conjunction with drawings and Examples.

The dark support wheel 6. of eccentric shaft 5. limits among the figure in 1. cylinders, 2. planing tools, 3. frames, 4. exciting sources is regulated self propelled chassis 10. synchromesh gears 11. central gears 12. shock absorbers of oil cylinder 7. walking CD-ROM drive motors 8. eccentric shaft CD-ROM drive motors 9. drives.

Planing tool (2) is fixed on the face of cylinder of cylinder (1) among Fig. 2 a and Fig. 2 b, cylinder is driven by walking CD-ROM drive motor (1) and is supported on the frame (3) by shock absorber (12), frame support is on the dark support wheel of limit (5), limit the height of dark support wheel to regulate by regulating oil cylinder (6), the eccentric shaft of exciting source (4) is driven by eccentric shaft CD-ROM drive motor (8).

It also can be short being fixed on planing tool on the cylinder and can being long, and Fig. 3 a is the schematic diagram that single straight planing tool is fixed on the cylinder face of cylinder.The helical form planing tool that is fixed on the cylinder is a kind of multi-head spiral, and Fig. 3 b is the schematic diagram that one of them single head helical form planing tool is fixed on the cylinder face of cylinder.

Single eccentric shaft is directly driven by eccentric shaft CD-ROM drive motor (8) and has produced the centrifugal force that causes vibration among Fig. 4 a.

Two eccentric shafts are to be driven by a pair of synchromesh gear (10) by eccentric shaft CD-ROM drive motor (8) among Fig. 4 b, do the rotation of counterturn, and their horizontal component is low mutually to disappear, thereby has only the double vibrations of vertical direction.

Two eccentric shafts are to drive a pair of synchromesh gear (10) by eccentric shaft CD-ROM drive motor (8) by central gear (11) to do the identical rotation that turns among Fig. 4 c, M is a moment of torsion among Fig. 4 d, α is a corner, as seen from the figure, because the centrifugal force of two eccentric shafts that rotate in the same way generation is oppositely offset because of collinear sometimes, sometimes then because of parallel not collinear and direction produces maximum moment of torsion mutually on the contrary, two last moments of torsion that form an alternation of centrifugal force.
