Description

The invention relates to loading machines and is intended to improve the working equipment of loaders.

The purpose of the invention is to simplify the management of the equipment.

FIG. 1 shows the working equipment of the loader, side view; in fig. 2 - the same, top view; in fig. 3 — jaw opening process; in fig. 4 - the process of closing When the equipment operates in a grabber mode, when it is necessary to load the material by scooping it with jaws, with the help of clamps 15, the gigs 11 are fixed in a certain position so that the front and back jaws 2 and 1 are arranged vertically. Then the locking pins 10 are removed, the bottom 6 is rotated clockwise relative to the hinges 9, installed in the upper jaws when scooping the loose 10 position and fixed by the pins 10. material; in fig. 5 - gripping the jaw at the time of pushing the rods of hydraulic cylinder loads; in fig. 6 shows the position of the loader bucket at the time of transporting the material.

The working equipment of the loader (Fig. 1) includes a bucket consisting of the back 1 and front 2 jaws interconnected by means of hinges 3. The front jaw 2 consists of the upper 4 and lower 5 parts of the side walls, the bottom 6

The ditch 16 developed forces are transmitted to the bucket, ensuring the rotation of the back jaw 1 counterclockwise. The front of the jaw 2, held by the grommets 11, is rotated clockwise relative to the hinges 3 of attachment to the posterior jaw 1. Thus, the process of opening the jaws (Fig. 3) is carried out.

At the moment of hydrocyc rods retraction, the frontal hydrotsis are retracted in the form of rezhes teeth with the edge 7 of 20 lindres 16 in the same way as when opening, the jaws 1 and 2 are closed, having developed the material with the cutting edge 8 and the knife 17 and scooping it (Fig. 4 ). Due to the fact that the bottom 6 is set in the upper position, the tooth 7 does not rub against the ground, which significantly reflects on the reduction of the energy intensity of the working process. The location of the cutting edge 8 at an optimum digging angle allows for the introduction of a process of scooping up the material with minimal energy consumption.

and a rear rectilinear cutting edge 8, which is rigidly connected to the lower parts of the 5 side walls and connected to the upper parts of the 4 side walls by means of hinges 9 and can be rotated and installed in different positions by fixing with the help of the fixing pins 10. The upper parts 4 of the side the walls are pivotally connected to the rods 11 mounted in the saddle bearings 12 pivotally mounted on the boom 13. To ensure a fixed installation, the grooves 11 have holes 14, and on the saddle bearings 12 clamps 1 are mounted 5 hydraulically driven. The bucket is controlled by hydraulic cylinders 16. The posterior jaw 1 is equipped with a cutting knife 17.

The equipment works as follows.

These jaws 1 and 2 are closed by developing the material with the cutting edge 8 and the knife 17 and scooping it (Fig. 4). Due to the fact that the bottom 6 is set in the upper position, the tooth 7 does not rub against the ground, which significantly reflects on the reduction of the energy intensity of the working process. The location of the cutting edge 8 at an optimum digging angle allows for the introduction of a process of scooping up the material with minimal energy consumption.

The control of the front 2 and rear jaws is achieved by hydraulic cylinders 16, which also serve to rotate the bucket as a whole, which simplifies the control system, since there is no need to install special hydraulic cylinders to rotate the front jaw 2. And, on the other hand, the presence of such special hydraulic cylinders control of the front jaw 2 makes it difficult to control from the point of view of ensuring the synchronous operation of the front 2 and rear and crushed materials above the level of 40 of it 1 of the jaws when the equipment of the machine is working The handyman operates in a grab mode, like a shovel when moving from a machine

In this case (Fig. 1), the posterior jaw 1 of the forks-hydraulic cylinders 16 reaches their synchronization and is attached to the anterior jaw 2, and days-na work, and it is also possible for the gripper 6 to be rotated relative to the hinges 9 various piece goods (Fig. 5) .

When the loader bucket is rotated at the moment of material transportation (Fig. 6), the gigs 11 move in the saddle bearings 12 in the mode of braking by the clamps 15,

fastening to the upper parts of the 4 side walls counterclockwise and fixed by means of pins 10.

To ensure the rotation of the bucket relative to the boom 13, they are switched off from work when opening the jaws 1, 2 tons of gi and fixatives 15. Under the action of forces developed by -

Claims of the invention Working equipment of the front plow. Material is developed by a cutting edge 7 in the form of teeth. The anterior and posterior jaws, bucket control hydraulic cylinders, which differ during operation of the equipment in the grab mode, when material is required to be loaded by scooping it with jaws, are fixed in a certain position by means of clamps 15 and 11, so that the anterior and posterior jaws 2 and 1 vertically. Then, the locking pins 10 are removed, the bottom 6 is rotated clockwise relative to the hinges 9, is set in the upper position and fixed by the pins 10. At the time the rods extend the hydraulic cylinder The ditch 16 developed forces are transmitted to the bucket, ensuring the rotation of the back jaw 1 counterclockwise. The front of the jaw 2, held by the grommets 11, is rotated clockwise relative to the hinges 3 of attachment to the posterior jaw 1. Thus, the process of opening the jaws (Fig. 3) is carried out. At the time of retraction of the rods of the hydraulic cylinders 16 in the same way as in the case of opening 0 of the linders 16 in the same way as in the case of opening 0 five These jaws 1 and 2 are closed by developing the material with the cutting edge 8 and the knife 17 and scooping it (Fig. 4). Due to the fact that the bottom 6 is set in the upper position, the tooth 7 does not rub against the ground, which significantly reflects on the reduction of the energy intensity of the working process. The location of the cutting edge 8 at an optimum digging angle allows for the introduction of a process of scooping up the material with minimal energy consumption. The control of the front 2 and rear jaws is achieved by hydraulic cylinders 16, which also serve to rotate the bucket as a whole, which simplifies the control system, since there is no need to install special hydraulic cylinders to rotate the front jaw 2. And, on the other hand, the presence of such special hydraulic cylinders for controlling the front jaw 2 makes it difficult to control the system from the point of view of ensuring synchronous operation of the front 2 and back of the first jaws when the equipment is operating in a clamshell mode,  - stays in a fixed position. Claims of the invention.
