Abstract
The utility model discloses a sliding turning loading machine working device constituted by a movable arm, a connection rod, a rocker arm, and a movable arm cylinder. The rocker arm and the connection rod are respectively hinged to a machine frame and the movable arm to form a four-bar linkage. The movable arm cylinder is respectively hinged to the machine frame and the movable arm. The telescoping of the movable arm cylinder can be used to drive the rising and falling of the movable arm. The movement track of the movable arm can be controlled by the four-bar linkage. The hinge point of the connection rod and the machine frame is disposed on the upper part of the rear side of a cab. The hinge point of the movable arm and the machine frame is disposed on the lower part of the rear side of the hinge point of the connection rod and the machine frame. The upper part of the machine frame has a structure with a high front part and a low rear part. By designing the proportions of connection rods of the four-bar linkage, the smooth movement track of a bucket on the front end of the movable arm can be guaranteed, and the retrieving of the bucket can be prevented as possible. The lifting height of the movable arm can be controlled by the telescoping length of the movable arm cylinder. The sliding turning loading machine has advantages of good visual field of the rear part of the whole machine, smooth movement of the working device, materials not easy to spill, large unloading distance of the whole machine, and good performance of the whole machine.
Description
Technical field
The utility model relates to a kind of loader, particularly glide steering loader.
Background technology
Glide steering loader is the compact loader of a kind of small volume structure, and common relatively big-and-middle-sized loader discharge height and unloading distance are unusual important technical parameter.At present; The equipment of general glide steering loader; Its version be the swing arm rear end directly and vehicle frame hinged, in position vehicle frame and swing arm is hinged with boom cylinder, during work under the boom cylinder effect; The path of motion of hinge-point is circular arc before the swing arm, the center of circle of this circular arc with swing arm after hinge be the center of circle.Above-mentioned equipment in the swing arm lifting process since track be circular arc therefore when giving rise to top, row behind the scraper bowl, the unloading distance diminishes.
Chinese patent specification sheets CN 2687076Y discloses a kind of glide steering loader that can increase discharge height and unloading distance, but this patent path of motion has flex point on top, and the equipment motion is not smooth, and material scatters easily.
Glide steering loader bumps easily when vehicle is stepped back or turn to even has an accident because the restriction of its structure and the layout of equipment cause its visual field, rear portion poor.
Summary of the invention
Goal of the invention: the purpose of the utility model provides and a kind ofly can increase discharge height and unloading distance, and path of motion is smooth again, but also can improve the glide steering loader in the visual field, rear portion.
Technical scheme: a kind of glide steering loader; Comprise swing arm, connecting rod, rocking arm, boom cylinder and reach vehicle frame; Said rocking arm is articulated in A, B 2 points with vehicle frame and swing arm respectively; Said connecting rod is articulated in C, D 2 points with vehicle frame and swing arm respectively, and boom cylinder is articulated in E, F 2 points, the lifting and the landing of the telescopic drive swing arm of boom cylinder with vehicle frame and swing arm respectively; Said connecting rod and vehicle frame pivotally attached C point are positioned at the top position of operator's compartment rear side, and said rocking arm and vehicle frame pivotally attached A point are positioned at the lower position of said C point rear side.
Distance between two hinge-point A of said rocking arm and the B is AB, and the distance between two hinge-point C of said connecting rod and the D is CD, and the distance between hinge-point B and the D is BD; Distance between hinge-point A and the C is AC, and the distance on the swing arm between two hinge-point B, the F is BF, and the distance on the vehicle frame between two hinge-point A, the E is AE; Distance between boom cylinder two hinged center E, the F is EF, makes that datum length is L, then AB=L; 0.9＜CD＜1.1L, 0.3L＜BD＜0.5L, 1.5L＜AC＜1.7L; 1L＜BF＜1.2L, 0.9L＜AE＜1.1L, 1.4L＜EF＜2.5L.
The utility model principle of work: a kind of glide steering loader, comprise swing arm, connecting rod, rocking arm, boom cylinder and vehicle frame, through said rocking arm and connecting rod respectively with vehicle frame and the hinged formation four-bar linkage of swing arm.Boom cylinder is hinged with vehicle frame and swing arm respectively, and the lifting and the landing of the telescopic drive swing arm of boom cylinder are through the path of motion of four-bar linkage control swing arm.The hinge-point of said connecting rod and vehicle frame is located at the top position of operator's compartment rear side, and said rocking arm and vehicle frame hinge-point are positioned at the lower position of the hinge-point rear side of connecting rod and vehicle frame, and said vehicle frame top is preceding high back bottom structure.The proportionate relationship of each connecting rod of design four-bar linkage guarantees that the path of motion of swing arm front end bucket is smooth and avoids the recovery of scraper bowl as far as possible.Control the hoisting depth of swing arm through the collapsing length of boom cylinder.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: 1, the visual field, complete machine rear portion is good, can avoid the generation of accident; 2, the equipment motion is smooth, and material is not easy to scatter; 3, complete machine unloading distance is big, and the complete machine performance is good.
