Description

The obstacle crossing type flowing snow scraper

Technical field:

The utility model belongs to environmental sanitation road snow cleaning apparatus field.

Background technology:

After the many cities snowfall of the north, need to consume great amount of manpower and material resources and manually clear the snow at present,, influence communications and transportation, bring inconvenience for people's production, life because of can not in time removing accumulated snow.In order not influence communications and transportation, vehicle pass-through, takeoff and landing etc., removing road surface accumulated snow generally is to spray snow melting agent or snow clearing machinery on the road surface.Yet definite and some uncertain obstructions such as cover for water supply and drainage manholes are all arranged on road surfaces such as highway, and these obstructions very easily damage the preceding shovel of snow clearing machinery in snow clearing machinery clears the snow process, caused economic loss virtually.If shovel height before adjusting again can't be clean with the Snowremoval on the road surface of clear.

Technology contents:

In order to solve the shortcoming of above-mentioned existence, the utility model provides in a kind of process that can snow clearing machinery clears the snow, shovel before the snow blower obstacle crossing type that shovel clears the jumps before the snow blower.

The car body junction plate that the utility model is installed on the car body is equipped with four connecting rod pull bars by the connecting rod gyroaxis, the internal thread pull bar is installed on the car body junction plate by hinge seat, thread is plugged in the internal thread pull bar, and the thread other end is installed on the bottom linkage rod gyroaxis of four-bar linkage structure, front end at four connecting rod pull bars is equipped with the connection support, connect support and be connected with axle sleeve by the gyroaxis axle, axle sleeve is fixedlyed connected with the preceding shovel support on being fixedly mounted on preceding shovel, preceding shovel lower end is equipped with scraper plate by hinge axis, in the scraper plate front snow scraping plate is installed, be separately installed with top link joint seat and lower link joint seat at the back side of preceding shovel and scraper plate, top link joint seat and lower link joint seat axle respectively are connected with upper connecting rod and lower link, and upper connecting rod is connected by the pull rod shaft axle with lower link, between pull rod shaft and hinge axis extension spring is installed; Have on the surface that connects support, movable revolution alignment pin places meta dowel hole or left side position dowel hole or right position dowel hole.

The utility model adopts the shaped steel welded construction as main body frame, mainly is made up of parts such as snow cave shovel body, four connecting rod elevating mechanisms, snow cave shovel slew gear, snow cave shovel pilot mechanism.By the car body junction plate, can be fixed on flowing snow scraper on the front chassis crossbeam of various car bodies.When not needing to clear the snow, can disassemble snow cave shovel easily and do not influence the normal use of vehicle, realize that a car uses more.The lifting of obstacle crossing type flowing snow scraper and left-right rotation are realized by operation manually.

Description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model Fig. 1 plan structure schematic diagram;

Fig. 3 is that the utility model Fig. 2 B--B is to the structure sectional view.

The specific embodiment:

The car body junction plate 4 that the utility model is installed on the car body is equipped with four connecting rod pull bars 3 by connecting rod gyroaxis 2, internal thread pull bar 6 is installed on the car body junction plate 4 by hinge seat 7, thread 5 is plugged in the internal thread pull bar 6, and thread 5 other ends are installed on the bottom linkage rod gyroaxis 2 of four-bar linkage structure, front end at four connecting rod pull bars 3 is equipped with connection support 9, connect support 9 and be connected with axle sleeve 24 by 8 of gyroaxises, axle sleeve 24 is fixedlyed connected with the preceding shovel support 23 on being fixedly mounted on preceding shovel 1, preceding shovel 1 lower end is equipped with scraper plate 14 by hinge axis 16, in scraper plate 14 fronts snow scraping plate 13 is installed, be separately installed with top link joint seat 11 and lower link joint seat 15 at the back side of preceding shovel 1 and scraper plate 14, top link joint seat 11 and lower link joint seat 15 axle respectively are connected with upper connecting rod 10 and lower link 17, and upper connecting rod 10 is connected by 18 of pull rod shaft with lower link 17, between pull rod shaft 18 and hinge axis 16 extension spring 12 is installed; Have on the surface that connects support 9, movable revolution alignment pin 19 places meta dowel hole 20 or left side position dowel hole 21 or right position dowel hole 22.

The concrete operating principle of the utility model is as follows:

The vehicle that flowing snow scraper is housed is when the non-duty that clears the snow is normally exercised, and the driver connects support 9 by hand rotation internal thread pull bar 6 by thread 5 pullings, drives snow cave shovel by four connecting rod pull bars and is in the rise state, to guarantee the normal enforcement of snow-clearing car.After entering the work highway section of clearing the snow, the driver puts down snow cave shovel by manual backward rotation internal thread pull bar 6.Four connecting rod elevating mechanisms are made up of 2,4 four connecting rod pull bars 3 of 4 connecting rod gyroaxises, connection support 9 and car body junction plate 4.Before after shovel puts down, promote flowing snow scraper by vehicle and push away long-pending to the accumulated snow in accumulated snow highway section and lead the roadside by preceding shovel inclined-plane.Flowing snow scraper has the left-right rotation function, from the meta dowel hole, pull up revolution alignment pin 19, can manually promote flowing snow scraper wraparound rotating shaft 8 and realize left-right rotation, revolution alignment pin 19 is inserted in the back that rotate in place in the dowel hole of position, a left side (right side), to satisfy the needs of different highway sections to the Snowremoval direction.

Consider that obstructions such as having Sewage well cover may exceed the situation on road surface, preceding shovel has added pilot mechanism.Pilot mechanism is made up of parts such as flowing snow scraper body 1, upper connecting rod 10, top link joint seat 11, extension spring 12, snow scraping plate 13, scraper plate 14, lower link joint seat 15, welding hinge and hinge axis 16, lower link 17, pull rod shaft 18.When obstruction such as well lid or small-sized stone and snow scraping plate 13 bumped instantly, snow scraping plate 13 was subjected to backward pressure to begin to drive the gyroaxis of

lower link

10,17 on top link joint seat 11 to turn round, and pull rod shaft 18 begins to make extension spring 12 anamorphic stretchings.Snow scraping plate 13 turns round avoiding barrier backward around snow scraping plate hinge axis 16, reduces injury that hard collision produces the driver and to the infringement of flowing snow scraper.After breaking the barriers, extension spring 12 is forced snow scraping plate is automatically reset.Snow scraping plate is made up of 5 groups short snow scraping plates, 4 groups of extension springs is installed on every group, after any one group of snow scraping plate and the obstruction collision, and the independent obstacle detouring of snow scraping plate and do not influence other snow scraping plate work.Scraper plate uses high-strength abrasion-proof steel plate to make, and uses screw to be installed in the scraper plate bottom, is convenient to be convenient for changing after the wearing and tearing.
