Abstract

FIELD: agriculture; machine building.

SUBSTANCE: present invention relates to agriculture. Sprinkler machine comprises pivotally interconnected spans comprising arranged on self-propelled cart (1) a trussed girder, consisting of pipeline (2) with sprinklers (3), braces (4), springs (5) and crossbars, made of a piece of pipe with flattened and bottom-bent ends. Spans of pipeline (2) have identical working cross-section and are made of two standard sizes – with length of 59.5 and 65.25 m. Span girder length of 65.25 m is mounted out of ten sections of braces (4), and in span span girder 59.5 m – nine sections of braces (4). In span of 65.25 m, first and last four sections of braces (4), including crossbars included in said sections, are made the same as the first and last four sections of brace braces (4) of 59.5 m. In structure of girders of both spans, pipeline (2) and strings (5) are located along parabolic curve, for this in each section of braces (4), braces (4), having an inclination towards middle of truss, are longer than braces (4) with slope towards end of girder.

Description

The present invention relates to agriculture and can be used in the construction of circular and frontal sprinklers, used for irrigation of crops.

The Kuban sprinkler machine is known (Kuban sprinkler machine. Lutsky V.G., Ilyin S.P. - M .: Agropromizdat, 1985. - 64 pp. 9-14. - analogue), consisting of articulated spans 52.5 m long, each span contains a truss truss with a pipeline, placed on a self-propelled cart.

The disadvantage of the analogue is that in most cases it is impossible to accurately select the length of the sprinkler machine to the size of the irrigated area, since the machine includes spans of the same length.

Known electrified sprinkler machine (RF Patent for utility model No. 173953 U1, IPC: A01G 25/09, publ. 09/21/2017 bull. No. 27 - prototype), consisting of spans of the same length articulated between each other, each span contains self-propelled trolley truss farm, consisting of a pipeline with sprinklers, braces, trusses and cross members made of a pipe segment with flattened and bent down ends.

The disadvantage of the prototype is that the sprinkler consists of spans of the same length, due to which in most cases it is impossible to choose the length of the machine for the dimensions of the irrigated area, and this in turn leads to the fact that part of the area may remain without watering.

The creation of two standard sizes of spans, different in length and having the same working section of the pipeline will allow you to more accurately select the length of the machine for the dimensions of the irrigated area. At the same time, in order to reduce the cost and ensure the simplicity of the machine design, the spans of two sizes should include as many identical and universal parts as possible.

An object of the invention is the creation of two sizes of spans, different in length and having a high degree of unification due to the use of identical and universal parts in their design, which will allow more accurate selection of the length of the sprinkler according to the size of the irrigated area, while ensuring low cost and simplicity of the sprinkler design cars.

The task is achieved by the fact that in a sprinkler machine, consisting of articulated spans, containing a truss mounted on a self-propelled cart, consisting of a pipeline with sprinklers, braces, trusses and crossbars made from a pipe section with flattened and bent down ends, where, according to According to the invention, spans having the same working cross-section of the pipeline are made in two standard sizes - 59.5 and 65.25 meters long, while the span farm having a length of 65.25 m is mounted from ten sections of braces, and the 59.5 m span farm has nine braces, with the first and last four braces in the 65.25-meter span, including the cross members included in these sections, made the same as the first and last four braces of the 59.5 m span, except Moreover, in the construction of the trusses of both spans, the pipelines and trusses are arranged along a parabolic curve for which, in each section of the braces, the braces having a slope towards the middle of the truss are longer than the braces with a slope towards the end of the truss.

In the spans of both sizes, all the braces and crossbars of the truss are made and installed mirror-like relative to the middle of the truss.

The braces in the middle section of the span of 59.5 m are made of the same length.

The braces in the two middle sections of the span of 65.25 m are longer than the braces in the middle section of the span of 59.5 m.

The cross members in the two middle sections of the span of 65.25 m are longer than the cross member in the middle section of the span of 59.5 m.

In the spans of both sizes, the water supply pipeline is mounted from universal pipes, with the exception of one pipe having fastenings for connection to a self-propelled cart.

In span farms of both sizes, universal sprengels of the same length were used to connect the brace sections.

In contrast to the prototype, the proposed irrigation machine may consist of spans of two different lengths, which allows more accurate selection of the length of the machine for the dimensions of the irrigated area and to minimize losses of irrigated area. And the use in the design of spans of both lengths of the same and universal elements and parts ensures low cost and simplicity of the design of the machine.

The invention is illustrated by drawings.

In FIG. 1 shows the spans of two sizes, front view, where:

a - span 65.25 meters long;

b - span 59.5 meters long.

In FIG. 2 shows the spans of two sizes, top view, where:

a - span 65.25 meters long;

b - span 59.5 meters long.

In FIG. 3 shows a section of braces of a truss truss.

The proposed sprinkler machine consists of articulated spans, which are made along the length of two sizes 59.5 and 65.25 meters (Fig. 1, 2). Each span contains a truss truss placed on a self-propelled cart 1, consisting of a pipeline 2 with sprinklers 3, braces 4, trusses 5 and cross members 6. Cross members 6 are made of a pipe segment with flattened and bent down ends, which ensures a one-point connection diagram of the ends of the braces 4 , cross members 6 and trusses 5.

The spans of two sizes have the same working cross-section of pipeline 2. Moreover, in the spans of both sizes, the pipeline 2 is mounted from universal pipes 7 and one pipe 8, which has fastenings for connection with a self-propelled truck 1. Moreover, the span of 65.25 m contains five universal pipes 7, and there are four of them in the span of 59.5 m. In addition, in the span of 65.25 m, the pipe 8 is shorter than in the span of 59.5 m in length.

Also, in the construction of truss spans of both sizes, the pipeline 2 and the truss 5 are arranged along a parabolic curve for which, in each section of the braces 4, the slopes 4 are inclined towards the middle of the truss and the braces 4 are longer than the braces 4 with a slope towards the end of the truss.

The span farm of 65.25 m is mounted of ten sections of braces 4, and in the span farm of 59.5 m there are nine sections of braces 4. Each section of braces 4 of the truss truss consists of four braces 4 and one cross member 6 (Fig. 3). In span farms of both standard sizes, universal trusses 5 of the same length were used to connect the brace sections 4.

In a span of 65.25 m in length, the first and last four sections of the braces 4, including the cross members 6 included in these sections, are made the same as the first and last four sections of the braces 4 of the span 59.5 m.

In the spans of both sizes, all the braces 4 and the cross member 6 of the truss are made and installed mirror-like relative to the middle of the truss.

Braces 4 in the middle section of the span of 59.5 m are made of the same length.

Braces 4 in the two middle sections of the span of 65.25 m are longer than braces 4 in the middle section of the span of 59.5 m.

The cross member 6 in the two middle sections of the span of 65.25 m is made longer than the cross member 6 in the middle section of the span of 59.5 m.

Using the proposed invention will provide the opportunity to equip the sprinkler with spans of two different lengths, which will more accurately select the length of the machine for the size of the irrigated area and minimize losses of irrigated area. At the same time, the use of identical and universal parts in the construction of spans of both sizes will ensure low cost and simplicity of the machine design.
