The closest analogue is a device for quick replacement of the working body in the description of the utility model to the patent of the Russian Federation No. 23298, IPC E02F 3/38 of 10.29.2001, publ. 06/10/2002, consisting of a traverse pivotally mounted with a cylindrical finger on the handle with the possibility of rotation from the hydraulic cylinder rod through the lever, rod and second cylindrical finger, which is a spatial welded structure of sheet material assembled on a supporting plate and equipped with stiffeners, eyelets for fastening on the handle and pull with standard cylindrical fingers and the main set and walls for attaching a standard working body, for example, a digging bucket, using a second computer lecta standard cylindrical fingers and pre-mounted on the eyes of the bucket.

Disadvantages: insufficiently high labor productivity.

Effect: increase labor productivity.

The technical result is achieved due to the fact that the device for quick replacement of the working body, containing a welded structure assembled on a supporting plate and equipped with holes for mounting on the handle with cylindrical fingers, characterized in that it contains a drive consisting of a worm gear, a hydraulic motor, one or two tilt cylinders with a rod in each, a hydraulic lock of the hydraulic lock pivotally mounted by cylindrical axes on the adapter with the possibility of rotation from the hydraulic cylinder rod through the axis and capture, hydror attachment distributor and control valve for controlling the flow of hydraulic fluid, driving the output shaft of the hydraulic motor through a worm gear, turning the gripper with mounted attachments and reversing rotation relative to the axis of the excavator handle, to which the working equipment is secured by means of a hydraulic lock ensuring its reliable fixation .

Due to the fact that the device is controlled by a driver from the cab of a machine, for example, an excavator remotely: the driver combines the holes of the handle of the excavator with the holes of the adapter, then installs the fingers into the combined holes, and connects the hydraulic wiring of the inventive device with hydraulic wiring and power supply excavator, using the remote control opens the hydraulic lock, the adapter inserts the attachment into the adapter, for example, a bucket and closes the hydraulic lock. The hydraulic lock is controlled by the hydraulic distributor of the attachment, the hydraulic control valve of the working fluid flows drives the output shaft of the hydraulic motor and, through the worm gear, rotates the gripper with the attached attachment, the inventive device is reversed relative to the axis of the excavator handle, as a result of which labor productivity is increased.

A comparative analysis of the proposed solution with the prototype allows us to conclude that the claimed utility model meets the conditions of patentability: it is new and industrially applicable.

A device for quick replacement of the working body is illustrated by the following drawings:

Figure 1 - device for quick replacement of the working body connected to the bucket of the excavator and its handle;

Figure 2 - device for quick replacement of the working body, the main view is a side section;

Figure 3 - device for quick replacement of the working body rear view;

Figure 4 - device for quick replacement of the working body in the position "Tilt to the right";

Figure 5 - device for quick replacement of the working body in the position "Tilt to the left."

A device for quick replacement of a working body, for example, an excavator, contains a drive 1 intended for rotation, tilt and quick change of a working tool, which consists of a worm gear 10, a hydraulic motor 12, one or two tilt cylinders 16 with a rod 8 in each, a hydraulic lock 9, the control valve of the attachment 6, controlling the flow of the working fluid in the hydraulic system of the attachment, the control valve of the flow of the working fluid 7 in the hydraulic system of rotation and tilt. The drive 1 is pivotally mounted by cylindrical axles 4 on the adapter 3, with the help of which, with the help of the fingers 15, the device is connected to the handle of the excavator 13 with the possibility of turning from the rod 8 of one or two tilt cylinders 16 through the axis 5 and grab 2. Inside the gripper 2 there is a hydraulic lock 11 , which allows you to change the working tool (a bucket for general land works, a planning bucket, a trench bucket, a maxillary grab, a petal grab, a forklift, etc.) without leaving the excavator cab

The inventive device operates as follows.

A device for quick replacement of the working body is placed on wooden bars in front of the excavator. To attach the device to the handle of the excavator, the holes of the handle of the excavator 13 are combined with the holes of the adapter 3, then the fingers 15 are installed in the combined holes, then the hydraulic wiring of the inventive device is connected with the hydraulic wiring and power supply of the excavator. The control of the device itself for quick replacement of the working body is carried out remotely from the excavator cab. Using the control panel, the hydraulic lock 11 is opened, the adapter 3 is inserted into the attachment adapter (not shown in the drawing), for example, the bucket 14 and the hydraulic lock 11 is closed. To attach the attachment, for example, the bucket 14 to the hydraulic lock 9, the hydraulic lock 11 is moved to the position “Open”, then the adapter 3 is inserted into the adapter of the bucket 14, the hydraulic lock of the hydraulic lock 9 moves the hydraulic lock 11 to the “closed” position. The hydraulic lock of the hydraulic lock 9 is controlled by the hydraulic distributor of the attachment 6. Using drive 1, the attachment can be turned to the right, left, the bucket 14 can be moved from the “back shovel” position to the “straight shovel” position, the hydraulic control valve of the working fluid flow 7 drives the output shaft of the hydraulic motor 12 and through the worm gear 10 rotates the gripper 2 with the attached equipment - a bucket 14. The drive 1 in addition to the function of rotation of the attached equipment also has the tilt direction of the attachment, the control valve for controlling the flow of the working fluid 7 drives one or two rods 8 of one or two tilt cylinders 16 and relative to the cylindrical axes 4, the drive 1 and the gripper 2 are rotated “clockwise” or “counterclockwise” through the axis 5 "At an angle of 40 °.

Technical and economic effect.

The device for quick replacement of the working body has been used since 2009 in the Central Black Earth Region on the basis of construction equipment of Enerpred-Region LLC, in the Krasnodar Territory on excavators of the Dormash road-building organization during the construction of the Olympstroy facility. The use of the claimed device provides an increase in labor productivity.
