Abstract

FIELD: agricultural engineering, in particular, mobile drop irrigation equipment.

SUBSTANCE: boom-type sprinkler unit has driving part and two girder extensions pivotally secured to driving part. Each girder extension is made in the form of mutually perpendicular vertical and horizontal girder parts. Left-handed and right-handed parts of girder are equipped with flexible belts, poles and struts. Irrigation heads are mounted on rigid water supplying belt aligned with girder horizontal parts. Driving part is provided with front and rear transverse beams secured on sprinkler unit side members. Left-handed and right-handed extensions of girder are positioned on rear transverse beam so that each of said extensions rotates around vertical axis of rotation of vertical girder. Horizontal parts of girder are connected to front transverse beam through mechanisms for moving said extensions to transport position. Flexible belts are hydraulically communicated with girder vertical extensions and with pump through U-shaped crank by water flow divider.

EFFECT: increased stability of boom-type sprinkler unit in transport position and reduced labor intensity and time for moving girder extensions to transport positions.

Description

The invention relates to the field of agricultural engineering, in particular to mobile irrigation equipment for irrigation by drip irrigation.

There is a method of transferring a front-mounted farm of a two-console sprinkler unit from its working position to transport and vice versa [1], which includes disconnecting the pump installation from the farm's water supply pipeline and rotating it around the vertical axis of tractor symmetry by rolling the farm rotary ring on the support rollers of the sprinkler unit frame. This method is implemented in the designs of two-console sprinkler units of the DDA-100 MA models.

The disadvantages of this method include rigid farm connections to the tractor frame, leading to large (unacceptable) angular oscillations of the unit when moving along field roads, and a limited view from the cab of the tractor being aggregated.

The closest technical solution is the console-type irrigation unit [2], which includes a running gear with two consoles pivotally mounted on it, each of which is made in the form of mutually perpendicular vertical and horizontal trusses having flexible belts, racks, braces and irrigation nozzles on one a hard water supply belt, in which, in order to use the unit for both sprinkling and irrigation along furrows, as well as to reduce the weight of the unit, each console is additionally equipped with a hard water supply them with a belt on which watering nozzles and ground supports are installed, as well as elements of a horizontal truss, and which is rigidly connected to a water supply belt of a vertical truss with the placement of sprinkler nozzles on it, while the ends of the racks of the horizontal and vertical trusses at the points of their connection with flexible belts are fastened between each other with stabilizing suspensions, and the posts of the vertical truss are equipped with hinged supports.

The disadvantages of the unit include limited opportunities for transport crossings.

The objective of the invention is to develop the design of a sprinkler unit with increased stability in the transport position.

This task is achieved by the fact that in a two-console unit, including the chassis with two consoles pivotally mounted on it, each of which is made in the form of mutually perpendicular vertical and horizontal trusses, having flexible belts, racks, braces and irrigation nozzles on a hard water-conducting belt, chassis the part is equipped with front and rear transverse beams mounted on the spars of the unit, the left and right consoles are placed on the rear transverse beam with the possibility of rotation of each console around vertical the axis of rotation of the vertical truss console and are connected by mechanisms for translating the truss consoles into transport positions with the front transverse beam, and the flexible belts are hydraulically coupled to the vertical truss consoles and the pump by means of a water flow divider and a U-shaped elbow. The left and right parts of the farm are located on the transverse beam of the chassis of the unit and are kinematically connected by a mechanism for translating the farm consoles into transport positions and vice versa.

The design of the two-console sprinkler unit is shown in figures 1-3.

Figure 1 schematically shows a two-console sprinkler unit, rear view.

Figure 2 is the same, left view.

Figure 3 is the same, plan view.

The double-console sprinkler unit (Figs. 1-3) includes a running gear 1 with two consoles 2 and 3 hinged on it. Each console 2, 3 is made in the form of mutually perpendicular vertical trusses 4, 5 and horizontal trusses 6, 7. Trusses 4 -7 have flexible belts 8, 9, 10, 11, 12 and 13, racks 14 and 15, braces 16 and 17. Sprinkling nozzles 18 are located on a rigid water-conducting belt of horizontal trusses 6 and 7. The intake device 19 is mounted on the rear cut of the chassis 1 unit by means of an L-shaped lever 20. The intake device 19 is equipped with a mechanical kite lifting. The lifting mechanism of the intake device 19 has a hydraulic actuator connected to the central section of the valve on the chassis 1. The chassis 1 is equipped with front and rear transverse beams 21 and 22. The beams 21 and 22 are mounted on the spars of the unit. The left and right consoles 2 and 3 are placed on the rear transverse beam 22 with the possibility of rotation of each console 2, 3 around the vertical axis of rotation of the vertical truss 4, 5 of the console 2 and 3. Horizontal trusses 6 and 7 are connected by mechanisms 23 and 24 with the front transverse beam 21 The positions of the horizontal trusses 6 and 7 in the transport position of the unit are mechanically locked to the side members of the chassis 1. Mechanisms 23 and 24 are made in the form of double-acting power cylinders hydraulically connected by high-pressure hoses to the left and right sections E hydrodistributor chassis 1. Flexible belts 25 and 26 are associated with the hydraulically vertical consoles trusses 4 and 5 and the pump 27 through the divider 28 and the flow of irrigation water U-shaped bend 29.

Two-console sprinkler unit operates as follows.

When irrigation is irrigated, the irrigation water from the open channel by the intake device 19 with the pump 27 running is first supplied under pressure to the U-shaped elbow 29, and then, through the flow divider 28, the irrigation water is sent to the flexible belts 25 and 26. The flexible belts 25 and 26 are hydraulically connected to vertical and horizontal trusses 4 and 5, 6 and 7 of the left and right console. Sprinkling nozzles 18 during the movement of the two-console unit are applied with a uniform layer of precipitation in the form of raindrops on the surface of the irrigated area. Upon completion of work in this area, the sprinkler is moved to another irrigated field. To do this, turn off the mechanical drive of the pump 27. Then, with a hydraulic actuator on the L-shaped lever 20, the water intake device 19 is put into an idle position. Next, the hydraulic actuators of mechanisms 29 and 24 are sequentially put into operation. When the hydraulic actuator rod 23 is pulled through a fist, the horizontal truss 6 of the left console 2 rotates around the vertical axis of symmetry of the vertical truss 4. The horizontal truss 6 is laid along the left side member of the chassis 1 and is mechanically fixed. In the same way, the right horizontal truss 7 is brought into the transport position. The transverse beam 22 on the side members of the chassis 1 is placed in the immediate vicinity of the center of oscillation of the tractor.

The sprinkler unit is brought to the working position in the reverse order.

When moving the sprinkler aggregate along field roads, the described construction in the transport position has minimal overall dimensions and is subject to minimal angular fluctuations in the longitudinally vertical plane of symmetry of the aggregate.
