Description

The technical solution relates to an attachment to agricultural or construction machines which are provided with a three-hinge mechanism either in the front or in the rear of the machine. The device is designed for handling loads.

BACKGROUND OF THE INVENTION

The hitherto known attachments of construction or agricultural machines intended for handling loads are formed by two arms. At least six linear hydraulic motors must be used to control the booms. The disadvantage is more complicated maintenance, higher cost of the machine and operation. The use of six hydraulic motors also increases the machine's weight.

In some prior art devices, the positioning of the crossbeam and spikes is solved only by the force of gravity. The disadvantage is inaccurate load control and stabilization of its position during stacking or ramping, which leads to reduced safety of work.

The essence of the technical solution

The attachment according to the proposed solution is intended for agricultural or construction machines which have a source of pressurized liquid and are provided with a three-hinge mechanism in the front and / or rear. The lower arm of the device is attached to the machine on one side and connected to the support on the other side. It is also equipped with a linear hydraulic motor.

The principle of the solution consists in that the opposite end of the support is fixed in the positioning segment, which is located on the main arm of the device. The main arm is pivotally attached to the machine with one end and the other end is divided into two arms of the fork weldment, terminated with lugs.

The location of the positioning segment is in the range of 24% to 48% of the length of the main arm, where the length of the main arm is given from the pivot axis to the connection with the fork. In a variant solution, a crossmember is attached between the two arms of the fork weld by means of pins to the eyes. The cross member is provided with two tines housed in conical bushes which are welded in the cross member. The crossbar is connected via a lever to a linear hydraulic motor.

Or it is attached between the arms of the fork by means of pins in the eyes of the bucket, which is connected via a lever or separate eye to a linear hydraulic motor. Alternatively, the solution can be used in such a way that a grab is attached between the arms of the fork weld using pins in the eyes. It is connected to a linear hydraulic motor and is provided with two additional hydraulic motors designed to control the grapple upper jaw.

The advantage is the compatibility of the attachment for different types of machines, the design of which allows the attachment of the attachment to the front or rear of the machine.

It also has the advantage of reducing the operator's assembly and disassembly requirements for only one person.

Examples

Example 1

An additional device according to the proposed solution was attached to the three-articulated mechanism in front of the tractor. The three-joint mechanism is controlled by a linear hydraulic motor 8.

The lower arm 1 is articulated on the one hand to the tractor and on the other hand it is articulated to the support 2. The opposite end of the support 2 is mounted in the positioning segment 9, which is located on the main arm 1 of the device at 30% the length of the main arm 4 from the pivot of the main arm L The length of the main arm I is given from the pivot axis to the connection with the fork 10.

The main arm 1 is attached to the machine by one end by means of a pin and eye and the other end is divided into two arms 11 of the fork 10.

In this case, the attachment is supplemented by a crossbeam 4, which is located between the two arms 11 of the fork 10 and is fixed by means of pins to the lugs 3. On the crossbeam there are two prongs 5, which are housed in conical bushes. These are welded in the crossbeam 4. The crossbar 4 is connected via a lever 12 to a linear hydraulic motor 6.

Example 2

In this case, the attachment is complemented by a welded sheet steel bucket, which is located between the two arms 11 of the fork 10 and is attached by means of pins to the lugs 3. The bucket weld is provided with a lever 12 which serves to stabilize the bucket position when handling loose materials .

The lever 12 can be replaced with a separate eye for the linear hydraulic motor 6.

Industrial applicability

The technical solution is useful for handling loads, with the possibility of stacking or ramping of materials and loads.
