Abstract

The utility model relates to a sliding type loading machine working device, which is characterized in that a movable arm is connected with a frame by a rocking rod and a connecting rod, so as to form a four connecting rod mechanism. The utility model has the advantages that under the action of the four connecting rod mechanism, the track line of a pin shaft which is arranged at the front end of the movable arm and connected with the bucket approaches to a straight line in the hoisting process of the movable arm, which causes the unloading distance at the upper part of the working device to be higher than the conventional type, and the utility model is especially excellent at the climax. Simultaneously, the rocking arm and the connecting rod are added, which is equal to that the movable arm is lengthened, and namely the maximal unloading height is also increased, so as to cause the sliding type loading machine working device to be more convenient when working.

Description

Sliding Loader Equipment

Technical field

The utility model relates to a kind of construction machinery and equipment, particularly a kind of Sliding Loader Equipment.

Background technology

At present, general Sliding Loader Equipment, its version be the swing arm rear end directly and the vehicle frame dumpling connect, in position vehicle frame and swing arm dumpling are connect with boom cylinder, during work under the boom cylinder effect, the track of hinge is a circular arc before the swing arm, the center of circle of this circular arc with swing arm after hinge be the center of circle.This arc track line, shown in accompanying drawing 2 dotted lines, when giving rise to top, row behind the scraper bowl, the unloading distance diminishes.Concerning common big-and-middle-sized loader, because its swing arm and fuselage size are bigger, the influence that the unloading distance diminishes is not obvious.And concerning wheel type excavator, its fuselage and swing arm size are all very compact, and unloading height influences clearly it with the varied slightly of unloading distance, and obtaining to unload preferably high is very important with unloading distance to wheel type excavator.

Summary of the invention

The purpose of this utility model just provides a kind of can increasing and unloads height and unload distance, is used for a kind of Sliding Loader Equipment of wheel type excavator.

Solution of the present utility model is such: connect with rocking bar 7 and connecting rod 4 between swing arm 3 and vehicle frame 5, form four-bar linkage.

The utility model has the advantages that: under the effect of four-bar linkage, the trajectory of the bearing pin that the swing arm front end links to each other with scraper bowl in the swing arm lifting process is close to straight line, shown in accompanying drawing 2 solid lines, make equipment than coventional type raising be arranged in the distance of unloading on top, particularly outstanding in the vertex performance, simultaneously, after increasing rocking arm and connecting rod, be equivalent to the swing arm that extended, promptly maximum is unloaded height has also increased, more convenient when making wheel type excavator work.

Description of drawings

Accompanying drawing is embodiment of the present utility model.

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is running orbit scheme drawings of scraper bowl.

The specific embodiment

The utility model includes scraper bowl 1, rotary ink tank 2, swing arm 3, connecting rod 4, vehicle frame 5, boom cylinder 6, rocking arm 7.

Connect with rocking arm 7 and connecting rod 4 between swing arm 3 and the vehicle frame 5, form four-bar linkage.

Rocking arm 7 is positioned at the top of connecting rod 4, and the length of connecting rod 4 is longer than rocking arm 7.

The utility model is the center swing with the straight line because the effect of four-bar linkage makes the track of swing arm 3 preceding hinge B when work, and when top, this trajectory increases the purpose of unloading distance to forward swing thereby reach.The trajectory scheme drawing as shown in Figure 1.After increasing rocking arm 7 and connecting rod 4 simultaneously, be equivalent to the swing arm that extended, promptly maximum is unloaded height has also increased.

Boom cylinder hinge E is in the place ahead of hinge G, hinge G on the overhanging end of swing arm, corresponding hinge H upside behind trailing wheel on the vehicle frame.

Rocking arm 7 is to adopt the double joint rocking arm; Connecting rod 4 is to adopt the double joint connecting rod.

In the present embodiment, make that datum length is L, AI=L then, AG=1.775L, GH=1.42L, IH=1.716L.

Claims

1, a kind of Sliding Loader Equipment includes swing arm (3), vehicle frame (5), it is characterized in that connecting with rocking arm (7) and connecting rod (4) between swing arm (3) and vehicle frame (5), forms four-bar linkage.

2, a kind of Sliding Loader Equipment according to claim 1 is characterized in that described rocking arm (7) is positioned at the top of connecting rod (4), and the length of connecting rod (4) is longer than rocking arm (7).
