This pendant, for each of the wheels includes a very complex, machined casting, mounted in one end of the respective axle, and which works together with expensive chrome shafts, which telescopios in a vertical glasses formed by casting in order to provide the movement of the wheel relative to the axle.
In another well-known self-propelled spraying machine eliminates the costs associated with machined casting and chrome shafts, due to the suspension bridges with a pair of connecting rods connected to one side of the main frame of the vehicle and on the other with each of the opposite ends of the bridge, and because of the equipment of the fifth connecting thrust, which performs the function of stabilizat the RA lateral stability. This suspension design has a drawback in which the bridge, when you move the suspension up and down, swinging in an arc relative to the points of attachment of the stabilizer bar, causing problems associated with the movement of the rear wheels strictly on its front.
Thus, the task that needs to be addressed is how to create a wheel suspension for automotive spray machine, which will not have the disadvantages associated with the suspension of the prior art.
According to the present invention results from the suspension of the axle of the vehicle, which includes a set of connecting rods.
The objective of the invention is to provide a relatively simple axle suspension of a vehicle, which includes traction suspension located so that the opposite ends of the bridge, when the movement of the vehicle over uneven ground, make a motion up and down close to vertical.
This task is achieved by suspending each end of the bridge for the frame of the vehicle using a pair of connecting rods, arranged so that, when viewed from the side, they are connected in parallel and, when viewed from above, one crosses the other.
Mentioned and other objectives will become apparent from the acquisition of the following description in conjunction with the attached drawings.

The barrels of the sprinkling devices are folded automatically, with each having a flexible element in its bottom. The flexible element is mounted on an adapter-hydrant of the irrigation pipe and secured on it with combined eye lugs and a finger. At the upper part of the barrel of the sprinkling device two supports with pushers are pivotally mounted. The pushers are attached to the protective casing. The casing is automatically thrust over the sprinkling device when reeling the irrigation pipe and yanking the supports.
EFFECT: this design enables to reduce irrigation erosion.
SUBSTANCE: selective velospraying machine, moved by the operator, provides a basic bicycle 1 with a side wheel and a pipe with nozzles 15 for liquid chemicals feeding of the treated crops. A high construction frame 2 is attached to the frame of the base bicycle with a lateral pipe with nozzles 15 for liquid chemicals feeding of the treated crops. The side wheel is fixed to the rack, which is connected to the construction frame by means of swing arm 5 with a movable element and the lock, and a horizontal rod, fixed in a side pipe with the possibility of extension. The nozzles 15 have a device 17 to install them and fix on the side pipe and horizontal rod, made with the possibility of regulation of their height and width to feet the selective plots.
EFFECT: design of velospraying machine is universal, because it allows lateral adjustment of the wheels and nozzles, depending on the width of space between rows of cultivated plots Its use will reduce labor costs involved in spraying.
SUBSTANCE: irrigation system consists of motorised vehicles with hydraulic device, irrigation devices, fixed pole with fixed pipe and turning knee, the control valve. Machine pipeline is connected to knee. Machine pipeline is equipped with irrigation apparatus and is placed on mobile carts with hydraulic drive. Last truck with hydraulic drive is equipped with crane setup device setting machine speed. Crane setup device is designed as a hydraulically driven valve. Hydraulically driven valve drain hole in the top cavity and is connected to hydraulic pressure pipe through another hydraulically driven valve. The hydraulic drive connected to protection system controls hydraulically driven valve. Control valve is mounted on the rotating knee and provided with a rod. Rod interacts with the guide groove of software unit. The software unit is fixed on the tube in the form of a disk. In the body of disk guide groove is placed, which reflects the reverse profile of the field on the front of machine movement. Irrigation machines are equipped with controls of flow characteristics. Controls of flow characteristics are made in the form of hydraulically driven valves. Hydraulic drives of hydraulically driven valves are separated with a membrane to form upper and lower chamber. The upper chambers of hydraulic drive are connected to the control tube of protection system. The lower chambers of hydraulic drive are connected to machine pipeline of the irrigation devices. The lower chamber of hydraulic drive adjusting spring is placed. Regulating spring interacts with the adjuster and the membrane of hydraulically driven valve through a per heel block.
EFFECT: design will enhance the functionality of the device
FIELD: irrigation equipment mounted on mobile sprinkler units for drop or fine-dispersion sprinkling systems.
SUBSTANCE: sprinkler unit has frame made in the form of three-dimensional construction comprising pipes mounted on vehicle equipped with pumping station and intake hose. Flexible water supply pipeline with sprinkler apparatuses is fixed on frame by means of cables. Water supply pipeline is made sectioned. Each section has segment and flanges connected with one another by means of carrier member made in the form of bent C-shaped profile or rolled part. Sections are connected with one another through adapter member made in the form of hollow spherical shell with disk arranged in meridian plane and with the help of fastening means. Adapter member is arranged in cavities at inlet end and at outlet end of adjacent segments of flexible water supply pipeline. Fastening means are made in the form of pins inserted into axially aligned openings of flanges and disks. Adapter member disk is connected through cable with frame of three-dimensional construction.
EFFECT: simplified construction, reduced metal usage, increased efficiency and improved distribution of artificial precipitation along flexible water supply pipeline.
