Description

The utility model relates to agricultural engineering, in particular to wide-spread agricultural units for tillage, sowing, irrigation, chemical processing and top dressing.

Known wide-spread agricultural unit containing a traction means, a frame, a mechanism for attaching a frame to a traction means and a modular-block arrangement of the working bodies (see ed. USSR certificate No. 1386067, M.cl. A 01 B 73/04, 59 / 04, publ. 07.04.88 g.).

A disadvantage of the known unit is the lack of compactness of laying the modules of the working bodies in the transport position: the unit is bulky, poorly maneuverable, long-base, additional transport wheels and many hydraulic cylinders are needed.

The closest device for the same purpose in terms of features is a wide-grip modular-block agricultural unit containing a traction means, a frame, a mechanism for attaching the frame to the traction

the tool and the modules of the working bodies (see US patent No. 4425971, MKI: A 01 73/00; publ. 01/17/1984).

As the creator himself noted, the known design allows to reduce only the width of the machine, which facilitates its transportation.

At the same time, the length of the machine remains the same.

This is due to the fact that the central section does not change its position when moving to the transport position, remains protruding from the rear of the unit and, as a result, is not compact enough in the transport position.

In addition, the transfer of a machine of known design to the transport position and vice versa is very inconvenient: the lifting frame is turned into a vertical position, and the side frames are folded onto a trailer. Since the side frames are pivotally connected to the lifting frame, when the lifting frame is brought into a vertical position, the side frames are also brought into the vertical position simultaneously with the lifting frame. Moreover, since only the central section is equipped with lifting cylinders, manipulations with the lifting of the side sections require the presence of assistants.

Thus, the technical result, the solution of which is claimed by the claimed utility model, is to achieve a higher degree of convenience of folding the machine into transport position and vice versa without assistants and a higher degree of compactness in transport position.

The specified technical result is achieved by the fact that in the well-known wide-grip modular-block agricultural unit, including a traction means, a mechanism for connecting to the traction means, equipped with support wheels, a frame with a central section mounted on it by means of a hinge, side sections, and modules are installed on each of the sections working bodies, and the sections themselves are mounted with the possibility of their transfer from the working position to the transport and vice versa, according to the utility model, the sections are mounted with zhnosti their translation alternately from the working position into the transport, first lateral sections vertically above the center section, and then the central section together with the side on the frame and attachment mechanism, wherein the width of each of the side sections equal to the width of the central section of capture or more fold.

At the same time, mounting supports are mounted symmetrically on both sides on the connection mechanism for fixing the side sections in them when they are installed in the transport position.

Installation of sections with the possibility of their alternate transfer from the working position to the transport: first, the side sections vertically above the central section, then the central section together with the side sections on the frame and the attachment mechanism can significantly increase the degree of convenience of folding the machine into transport position and back without assistants and provide more a high degree of compactness of the machine in transport position. Moreover, this is ensured precisely under the condition that either the width of the grip of each of the side sections is equal to the width of the grip of the central section, or if their width is an integer number of times larger (multiple times).

This is ensured, firstly, due to the fact that with the claimed scheme of the utility model, the length of the unit is significantly reduced when it is transferred to the transport position (compared to the closest analogue - to the length of the central section), since it occupies a vertical position - it is mounted on the frame.

Secondly, it is the implementation of the transfer to the transport position in turn, which allows the data

manipulations without attracting assistants, since the claimed scheme is not bulky and convenient.

The presence on the joining mechanism on both sides of the mounting supports further improves the degree of convenience of folding the machine into transport position and to achieve a higher degree of compactness of the machine in transport position.

This is achieved by fixing the side sections in them when they are installed in the transport position in their most convenient and most compact position.

The inventive utility model is illustrated by drawings.

In Fig.1 shows a diagram of the unit in the working position; figure 2 is the same side view; figure 3 is the same in the transport position.

The unit contains a traction means (tractor) (not shown in the diagram), a frame 1 with a mechanism for connecting 2 to the traction means, paired transport wheels 3, hinges 4, a central section 5, hinges 6 of the side sections 7, the central 8 and side 9 hydraulic cylinders, supporting -regulating field wheels 10 and mounting bearings 11 on the frame 1 of the side sections 7, rack 12

for storage when the unit retreats from the tractor, the control hydraulic cylinder 13 and track dividers 14 for cutting the soil along the track of the tractor. Tracking devices 14 are controlled by a hydraulic cylinder 13.

To reduce pressure on the soil, the wheels are paired

The working bodies in the sections can be different for any field technological operations.

The unit operates as follows.

Folding the unit from the working position to the transport is as follows.

By the first step, by means of hydraulic cylinders 9, the lateral sections 7 are mounted vertically above the central section 5 by hinges 6 in a transverse vertical plane.

The second stage, through the Central hydraulic cylinder 8, the Central section 5 is mounted on the frame 1 and the connecting mechanism 2 with the fixing of the side sections 7 in the mounting supports 11.

Thus, the agricultural machine is installed completely on the frame, the unit receives a compact,

highly maneuverable, convenient and reliable construction.

The transfer to the working position is performed in the reverse order.
