Abstract

The utility model relates to a palette knife for ice-breaking snow-removing on road surface in urban. The pressure which decides the sliding friction between the edge of the palette knife and the road surface comes from the resultant force of the gravity and elastic force of a spring; the whole palette knife is broken up into parts, and the rigidly fixed edge of the palette knife is changed to be able movable within a certain range. The palette knife is made to become a flexible structure, and the acting force of the palette knife is adjustable. The palette knife can automatically avoid various obstacles on the road surface within a certain range. The palette knife is suitable to be used for breaking snow and ice in various status on the road surface in urban. The utility model has the advantages of simple structure, high reliability, high work efficiency and stable work.

Description

Automatic palette knife for snow breaker

Spatula is used in the cleaning of a kind of urban pavement, particularly is applicable to the open ice automatic spatula of snow removing machine of urban pavement in winter.

Present all kinds of snow removing machine spatuves that open ice, according to one's analysis, more ubiquitous deficiency is: just and not gentle, can not adapt to roughness pavement automatically, thereby or can not the clean ice and snow of close proximity to ground spatula, or easily collapsed (top) bad cutting edge, vexed car or destruction road surface by all kinds of obstacles.

The purpose of this utility model is to overcome above-mentioned snow removing machine deficiency, releases the parts of the city of suitable China's national situation with the certain obstacle in automatic adaptation road surface of all kinds of snow removing machines, and the snow removal with machine range of application of China is enlarged rapidly.

Main points of the present utility model are to determine the pressure of the force of sliding friction on the edge of shovel and road surface to make a concerted effort from deadweight and spring, so force of sliding friction is relatively rationally and stable during work; Being generally whole wide (1～3 meter) spatula, break the whole up into parts, combine by narrower (20～50 centimetres) spatula, thereby horizontal Uneven road fitness is increased; Be generally rigidly fix the edge of shovel change into because of fulcrum 1. obstacle insurance bearing pin 7. and the spatula active pin shaft 9. move automatically in certain limit, so vertical Uneven road fitness is heightened.

Accompanying drawing (schematic diagram) illustrates that Fig. 1 is a front view, and Fig. 2 is the partial enlarged drawing of Fig. 1, wherein: 1. fulcrum; 2. beam; 3. adjustable spring; 4. positive stop; 5. rise and support; 6. cam; 7. obstacle insures bearing pin; 8. spatula arm; 9. spatula active pin shaft; 10. the edge of shovel; (11) framework; (12) spiral propeller; (13) the wide-angle activity is opened ice to hammer into shape and is rolled; (14) main car.

One of the utility model embodiment: the utility model can roll (can be that 87200028 they " patent applications " constitute by my application number mainly) and spiral propeller (12) (two is that in the middle of the reverse acting spiral blade is pushed ice and snow to dished out ice and snow by centrifuge blade in the centre through parabolic tube orientation with the wide-angle activity hammer that opens ice.) be used, constitute urban pavement complete function, the desirable snow removing machine that opens ice.

The utility model, except that the edge of shovel 10. available sometimes as required nonmetal, all the other all are made of metal.1. fulcrum is 45 degree with the garden heart line of spiral propeller (12) and ground angle.Positive stop is fixed on beam and 2. goes up, when it by framework (11) when blocking beam outline line up and down 2. constitute by the concentric arc of spiral propeller (12).An adjustable spring 3. end is pressed under the adjusting screw that links to each other with framework (11), and an end withstands on positive stop and 4. goes up, and its adjustment can influence the frictional force between the edge of shovel and the road surface, also can influence the operating angle of the edge of shovel.Rise to support and 5. to be provided with 2 projections, top one with a cam little cam generation enhanced feature 6., following one just in time withstands on second little cam and plays the disengaging effect.Support upper end and the beam 5. that rise is 2. hinged, and the middle part hangs up the retainer spring that 2. links to each other with beam, because the effect of retainer spring.Rising, it is inoperative to support the general cam that breaks away from, and retainer spring just will rise the support bullet rapidly to counterclockwise 6. matching with cam when 8. counterclockwise touch because of the road surface has obstacle to be subjected to the spatula arm lower end of the support of rising, 2. beam is risen fall reposition behind the certain altitude at once, thus make beam 2. the hinged spatula in lower end escape obstacle and the operate as normal that automatically resets.The utility model can be established 4 place's springs, first place be adjustable spring 3., being directed downwards of power; Second place be located at obstacle insurance bearing pin force on 7. the spatula arm 8. the up time direction go to position shown in Figure 1, meet obstacle and can reverse, the elastic force of this spring should be able to be to overcome the force of sliding friction of the edge of shovel; The 3rd place's spring is located at the spatula active pin shaft and 9. goes up, and counterclockwise 10. spatula is pressed to the road surface together with the edge of shovel in 30 degree scopes, and 10. the edge of shovel is that 30 degree are to 60 degree with the ground angle; The everywhere spring be located at rise support 5. and beam 2. between, active force upwards plays the role of positioning.So-called little cam is meant that 6. cam go up set and support relevant " steamboat " of projection 5. that rise.

Cam 6., spiral propeller (12), the wide-angle activity driving force that hammer rolls (13) that opens ice preferably comes autonomous car (14).
