Abstract
The utility model belongs to engineering machinery class and constitutes a connecting rod working mechanism which is composed of two parallel oil cylinders, a scraper bucket, an upper and a lower connecting rods, a front and a back buckets. The dual-cylinder drawing type fork conveyer completes a plurality of shovel, loading, transportation and unloading of the earthwork under the traction of a tractor and the control of a distributing valve. The dual-cylinder drawing type fork conveyer can be broadly applied to various earthwork work such as agriculture, water conservancy, traffic and kiln field, completing the work such as the excavation, the transportation and the levelling of the earthwork. The walking section of the utility model is four wheel type or two wheel type. Compared with the products of the same category, the utility model has the advantages of simple structure, light weight, low cost, higher efficiency, little stress on members, and rapid and stable action.
Description
The utility model belongs to the engineering machinery class.It makes traction power with crawler tractor, with two cylinder actions arranged side by side of tractor hydraulic system control, makes the equipment of this scraper be in various operating positions respectively, realize scraper to shovel, the dress of the earthwork, transport, unload, control various functions such as soil.This scraper can be widely used in the construction of agricultural, water conservancy and other various ground workss, the excavation of finishing cubic metre of earth, carrying, work such as smooth.
At present, China is a large amount of use with 75-80 horsepower crawler-drawn scraper, mainly be a kind of towed scraper of single hydraulic oil cylinder driving.This single cylinder scraper push and pull system complexity, some parts damages because of forcing stressed being easy to, oil cylinder maximum output direction and scraper maximum weighted direction are inconsistent, must remedy its undercapacity to increase the oil cylinder cross section, this scraper complicated integral structure, manufacturing is many with steel, and cost is higher.
The twin-tub towed scraper that the utility model proposes with adopting a kind of fairly simple push and pull system, makes to simplify the structure, weight saving, and cost reduces.Adopt two rod ends upwards, the minor diameter oil cylinder that is arranged in juxtaposition except the stability that makes equipment is improved, has also solved oil cylinder and has exerted oneself and be subjected to the inconsistent problem of force direction.Push and pull system is stressed less, and the power consumption of tractor oil pump is reduced, and this has also relatively improved the efficient and the application life of tractor.
The utility model is to finish its every function as follows:
Fig. 1 is twin-tub towed scraper (four-wheel-type) elevation; Fig. 2 is a four-wheel-type type vertical view, mainly shows the mutual alignment and the shape of frame, oil cylinder, wheel part; Fig. 3 is a two-wheeled type vertical view, mainly shows the mutual alignment and the shape of frame, oil cylinder, wheel part.
As shown in Figure 1: link 1 links to each other with the towing plate of tractor by connecting shaft Xiao, and oil pipe 2 joins with the tractor hydraulic pipeline. Under the traction of tractor, the distributing valve handle of pilot control tractor enters hydraulic oil or withdraws from oil cylinder 19, makes cylinder piston rod 22 make stretching motion, thereby finishes scraper mechanical shovel, dress, transport, unload various functions.
1), the both sides of scraper bowl 10 are furnished with oil cylinder 19 and two power connecting rods 13,14. Two power connecting rods 13, an end of 14 respectively with scraper bowl semiaxis 12,23 hinged, the other end is respectively hinged with Xiao's axle of frame longeron 26 and frame bearing 25. Oil cylinder 19 is hinged on frame cylinder seat 18, and the upper end hole of piston rod stomidium and connecting rod 13 is hinged on the scraper bowl semiaxis 12 with one heart. When piston rod bounces back, the semiaxis 12 on the scraper bowl 10,23 connecting rod 13,14 and the effect of piston rod under, scraper bowl is fallen, in blade 20 shovels of scraper bowl bury. This namely shovels dress operating mode (seeing shown in Fig. 1 fine line), and under tractor-drawn, soil layer enters scraper bowl.
2), front bucket 9 is hinged by Xiao's axle 11 and scraper bowl.When piston rod bounced back, front bucket fell with scraper bowl.When the bogie wheel on the front bucket 8 was fallen on the wheel card 7, front bucket fell to stopping.When scraper bowl was in shovel dress operating mode, front bucket was under the control of a wheel card and Xiao's axle 11, and its end opening opens an enough big size to bucket blade, made soil layer go into bucket smoothly; Enter the soil block in the bucket, also no longer flow out because of the retaining soil effect of front bucket.
3), the action of back bucket 15 is subjected to the control of the guide wheel 16 on scraper bowl semiaxis 24 and the frame bearing 25.Back bucket wall and semiaxis 24 are hinged, and guide wheel 6 is installed in the channel suspending rail 27 of back bucket side plate.When bucket motions, the back bucket movement therewith, guide wheel 16 is being controlled the back bucket end opening to the closing up of scraper bowl rear portion (shovel dress and transportation operating mode) or open (unloading geotechnological condition), cooperates scraper bowl to finish the various action functions that the shovel shipment is unloaded.
4), when shovel dress finishes, when piston rod was overhanging, scraper bowl was mentioned in soil layer thereupon.When promoting certain altitude, front bucket end opening and bucket blade place close up.At this moment, the back bucket end opening still tightly closes up with the scraper bowl rear portion under guide wheel and channel suspending rail effect, all can not run off in the soil block front and back of filling in the bucket.This promptly transports operating mode, shown in Fig. 1 heavy line.
5), when piston rod continues when overhanging from transporting the operating mode position, the scraper bowl base plate begins to recede.The front bucket end opening is under the entrusting of bucket blade, and bogie wheel leaves a wheel card; Back bucket is under the guide wheel effect, and its end opening opens.When reaching range outside the piston rod, the scraper bowl base plate reaches maximum value to ground elevation, has also opened enough big size between back bucket and the scraper bowl base plate, and soil block draws off in struggling against rapidly.This promptly unloads geotechnological condition, sees shown in Fig. 1 chain-dotted line.
Running gear of the present utility model can divide four-wheel-type and two-wheeled two kinds of types.The trailing wheel 17 of four-wheel-type, its axletree and frame rear portion are connected; Front-wheel is by the spherical axle 5 on the hitch frame 3, is hinged with the bow beam of frame front, and front-wheel can be done 90 ° of revolutions under bow beam, makes scraper turn flexibly (seeing Fig. 1, Fig. 2).Two-wheeled is under the constant situation of oil cylinder and each equipment structure, only hitch frame 3 and frame 6 is integrated, and does suitably to simplify to become to make new frame 28, and wheel is installed in the appropriate location in frame 28 outsides, the two-wheeled type, see Fig. 3.This type has obvious advantage on simplified structure and reduction cost.
When the tractor hydraulic system fuel cut-off, when scraper is in off working state, depositing and transporting for ease of scraper, special axle sleeve and the slotting Xiao's axle 21 established on the frame longeron inserted Xiao's axle and can be inserted in corresponding Xiao hole of scraper bowl wall by axle sleeve, makes scraper bowl be in the state of transportation operating mode.
