The invention relates to a device for processing fruit trees, berry bushes, vegetables for chemical protection against pests and diseases, as well as foliar feeding, economical watering with a wide dispersion in the conditions of farms and garden plots.
Known used in private gardens and even farmers portable sprayers, consisting of a reservoir for the working fluid from the filler neck filter, hand pump and outlet tube hose (see SU # 246207, IPC AM 7/00).
Known portable sprayers, which are filled with fluid and pumped up in her air-operated actuator (see the patent of Ukraine UA No. 23404, CL AM 7/00, the Federal Republic of Germany patent DE No. 19511885, CL AM 7/00). The spray liquid flows in these sprayers are driven by compressed air from the foot or hand pumps.
The disadvantage of these hand and foot sprayers: low pressure spray, weakening as emptying the tank, hard work during the swing of the air, a short tubular arm, odnorazovyy spray. As a result, they are not suitable for spraying tall fruit trees and have low productivity.
Known machines for chemical protection of plants - machinery sprayers pumps. Working bodies of these sprayers consist of tanks, pumps, filter is in, pressure regulators, nozzles, spray systems, and fuel devices (See. Tutorial Wemhoener, IV Gorbachev "Agricultural machinery", str...218. Moscow, "Colossus", 2004 (1)).
In the engine sprayers set, piston, centrifugal, gear, diaphragm, roller and rotary pumps. The main characteristics of the pump flow (l/min) and fluid pressure (MPa). Vibrating pumps in machinery chemical plant protection is not applied as thin and do not provide high performance in large farms.
However, in gardening and farming the use of cheap and small sprayers on the basis of the vibration of the pumps will allow a significant increase productivity and eliminate manual work by pumping air into pnevmopistoleta with a working tank liquid not more than 10 litres.
The spray system in the engine sprayers are used to move sprayed fluid flow and applying it to the object processing plants.
There are distribution system: fan, hose, hoses [(1) str...226].
The closest technical solution to the claimed invention is a hose [(1) str...226. .VI.7].
The hose is designed for spraying young manually garden is in, odinokostoschih trees, various landings and storage space. The basis of it is a pipe, one end of which is fixed the head of the handpiece, the other tee. In the tube is a rod, which is fixed to the handle with an internal screw thread. The handle is screwed on the fitting, the end of which is screwed into the tee. On the rod is fixed swirl with screw channels and rubber washer. The tip is blocked spray washer with a hole for passage of a chemical, the washer keeps the lid.
The space formed between the spray plate and called swirl chamber swirl. The length of it and, consequently, the capacity to regulate rotation of the handle, screwing it onto the fitting and thereby moving the stem and swirl.
With the approach of the swirl to spray the washer spray becomes wider and shorter, the dispersion increases, consumption decreases. Depending on the pressure in the injection system and the diameter of the hole of the spray washer height of the jet can be 7...12 m to stop spraying, turn the handle up, and the rubber washer closes the opening of the spray washer.
Liquid is supplied to the hose through the sleeve length of 10 m is attached to the nipple. Attached removable spray washers with holes of diameter 3, 4, 5 and 6 mm
The hoses will elektuur sprayers many brands. The supply hoses nozzles, forming a concentrated stream of high altitude due to head pressure.
Well-known high-performance hoses, as they work from the machine sprayers expensive, energy-intensive, complex device and because they are applicable in large farms and not in farms and private gardens, where trees besides thickened and the machines have no place to sleep. The flow of the spray liquid from the great artesian pressure in machine hoses is also great and spray close to the large-droplet and in farmers ' orchards enough spray fine and even spray. The guide pipe from the well-known hose short hose sleeve heavy and height of the pressure of the spray pattern is achieved by a powerful pump and pressure of the jet with high pressure.
