Description

FIG. b

The invention relates to the construction and road engineering, namely to front loaders with increased dumping height.

The purpose of the invention is to simplify the management of the unloading of the bucket by ensuring that it is driven by a single cylinder.

Figure 1 shows the loader when typing the immersed material, a general view; in FIG. 2, the same with the bucket upturned; fig. 3 - the same, with a lift to the upper position of the bucket; figure 4 - the same, in the unloading position; Fig. 5 shows a section A-A in Fig. 2, a variant of the arrangement and fastening of the elements of the device; 6 is a kinematic diagram.

The loader with increased discharge height consists of boom 1, power cylinder 2, rocker arm 3 pivotally mounted on a rigid crossbar boom 1, intermediate frame 4 pivotally mounted on the free end of boom 1, bucket 5 pivotally fixed at the front of frame 4, two shoulders the lever 6 mounted on the frame 4 can be rotated and interacting with the bucket 5 by means of the rod 7. The double-arm lever 6 is connected by the rod 8 to the lower link 9 of the rocker arm 3, in which in the middle part, i.e. on a smaller turning radius, fixed t ha 10 intermediate frame 4.

The boom 1 is attached to the portal 11 of the base chassis. The boom is raised and lowered by the power cylinders 12.

The loader works as follows.

The bucket 5, located on the supporting surface (Fig. 1), is inserted into the immersion material by the movement of the base chassis. Turning the cylinder 2 on the stem extension, rotates counterclockwise of the rocker arm 3, which, with the bolts 10 and 8, simultaneously moves the intermediate frame 4 and the double-arm lever 6, which, in turn, the hard 7 rotates the bucket 5 to the position shown in FIG.

The boom is raised by cylinders 12 when turned on to extend the rods to the position shown in FIG. The kinematic link is designed in such a way that when lifting, the bucket is aligned in the upturned position without switching on the cylinder 2.

The unloading of the bucket 5 is made by turning on the cylinder 2 to retraction of the rods. In this case, when the rocker arm 3 is rotated, the movement of r g 10 and 8, which in

turn, move the intermediate frame 4 and the two shoulders lever 6 with the thrust 7 and thereby unload the bucket 5, as shown in Fig. 4.

T ha 10 is fixed on a small radius

rotation of the rocker arm 3, as a result of which the intermediate frame 4 makes a small angle of rotation relative to the boom 1, and therefore does not allow the axis of rotation of the bucket 5 to be lowered, and this provides

increased unloading height, T ha 8 is hooked on a larger radius of rotation of the rocker arm 3, as a result of which the double-arm lever 6 makes a greater angle of rotation and when moving on its outer shoulder

Claims (1)

Stage 7 of the bucket provides the necessary rotation relative to the frame during unloading. The increase in shoulder B on the lever b (figure 4), you can increase the discharge angle while maintaining the dimensions of the other links. The optimum discharge angle is 45 °. Claims of the Invention A loader with an increased dumping height, comprising a longitudinal vertical plane. a hinge-lever system, including mounted on its chassis with a rotatable boom, attached to the last middle part {- rotatable arm, connected to the chassis and upper arm of the rocker arm by the upper arm of the rocker arm, mounted on the free end of the boom turning the intermediate frame mounted in its front part with the possibility of rotation the bucket mounted on the frame with the possibility of rotation of the double-arm lever and the gi, one of which is connected to the frame and the lower arm of the rocker arm with its ends, and the other with the bucket and the upper end of the two shoulders lever, characterized in that, in order to simplify the management of the unloading of the bucket by ensuring that it rotates by one cylinder, it is provided with an additional thrust connected to the lower arm of the rocker arm and the middle part of the two shoulders with its ends lower end. 7 j 2 4 and // 4 Ј J / 5 9 , / / // 45 7/75 A FIG. 2 figure 1 s 12 Editor E.
