Modern models of backpack sprayers-sprayers are distinguished by reliability, efficiency and high ergonomics. Such an apparatus can be considered not only as a garden assistant in protecting plants from insects. If necessary, some models can be used as a tool for paintwork. Compared to other varieties of sprayers, manual backpack garden sprayers are easier to handle and less demanding to maintain. True, you cannot service large areas with such a device, so there is no need to talk about wide universality.
Sprayer device
The basic structure of such units provides for the presence of three mandatory components. This is a container that contains a chemical or other working fluid, a pumping mechanism, and the spray channel itself. As for the tank, that is, the tank, it can have a different volume and is made from a wide range of materials. The most practical solution is polypropylene and its modifications. The material is lightweight, durable and does not affect the contents. Also, a backpack sprayer contains one or another fluid supply system. This can be a pump-action mechanism, and a drive motor system and even a battery. Regardless of the tank and the pumping system, almost all models of sprayers have similar devices for discharging the working mixture, that is, sprayers.
Main characteristics
The models are quite diverse, each parameter is of great importance in the process. For example, the tank capacity of modern backpack sprayers varies on average from 5 to 25 liters. On the one hand, it may seem advantageous to purchase the most capacious model, since it will have to be refueled less often, but, on the other hand, it will be harder. Do not forget that in the process of operation, the support for the unit will be the user's shoulders. The weight is from 7 to 10 kg, which should also be taken into account. As practice shows, those who use a backpack sprayer, 12 liters is enough to work in a private area of medium size. But there is another important characteristic - this is performance. It is determined by the volume of fluid release in 1 min. This indicator depends on the type of drive mechanism, but in the simplest models it varies from 0.7 to 1 l / m.
Varieties of models
As mentioned above, the fundamental difference between backpack sprayers is the type of mechanism that provides spraying. There are three different approaches to implementing this part. The basic and traditional is the pump action manual mechanism. Such an aggregate is driven by pumping provided by muscular effort. A backpack engine powered by gasoline will help rid yourself of physical exhaustion . These models have the highest performance and a decent spray radius. The advantages are attractive, but they will have to pay for the exhaust from fuel processing, noise with vibrations and the high cost of the sprayer itself. And this is not to mention the cost of refueling with gasoline, although such devices consume a little. An alternative solution could be a cordless sprayer. It is also profitable with good performance, but, unlike the gasoline model, it is environmentally friendly, low-noise and weighs less. But its working time is limited by the capacity of the battery, so you should initially calculate the volume of a one-time expense if there is no access to the mains on site.
Additional functions
In terms of the spray system itself, manufacturers do not indulge in new technologies, but it is understandable. The existing principle of fluid supply through nozzles with the possibility of adjustment is optimal and additional optional difficulties can only be harmful. Therefore, the main emphasis is on improving ergonomics. Many manufacturers are improving the design of the rear of the device, providing it with special linings. Also, for ease of installation on a horizontal level plane, the backpack sprayer is equipped with a special stand that can be removed to facilitate weight. Some models optionally include additional booms that extend the channel through which spraying is performed.
Reviews about the models "Beetle"
We can say the basic solution that is used by most Russian summer residents and gardeners. The products of this brand attracts attention with a simple design, affordable price tag and unpretentiousness in care. An example is the Cicle OG-112 modification, which has a capacity of 12 liters. Users of this sprayer note its reliability and modest mass, due to which acute physical fatigue is not observed even after prolonged use of the device. In addition, the Beetle backpack sprayer is provided with a filtration system that prevents solid inclusions from entering the working channel. This addition is important both in terms of the reliability of the apparatus, and in terms of maintaining the health of vegetation. Owners of backpack bucket sprayers “Beetle” also note the convenience of a telescopic boom, which is easily adjustable, adapting to the needs of specific conditions and tasks.
Gardena Model Reviews
For ordinary gardeners, the manufacturer produces a line of Comfort sprayers. It presents models with different displacement, but most of them are based on a pump-action mixture supply system. From the point of view of the user, an important difference of this product is its manufacturability. Gardena has always been famous for its high-quality designs and careful selection of materials, which is why polypropylene sprayers do not cause complaints about strength and durability. It is the technological development of models that causes more interest in many. So, even a 5 L pump-operated backpack sprayer is equipped with a filling indicator, which is convenient in working with sensitive plants. Of course, there are more voluminous devices in the Gardena line, designed to serve public areas, gardens and park areas.
Solo Model Reviews
Modification 417 in the Solo line is a sprayer provided with a 12 V lead-gel battery. According to users, this model is convenient when working with greenhouse plants. The fact is that, unlike gasoline devices, battery models can, in principle, be used indoors. And if the pump-action apparatus is inexpedient to use in the maintenance of large areas, then the manual backpack sprayer on the battery is quite suitable for such tasks. Moreover, version 417 stands out against the background of competitive models with batteries in that one charge is enough to produce a large volume of a chemical - on average, users talk about 180 liters.
ECHO Model Reviews
In the line of this manufacturer, the SHR-170SI model deserves attention. It should be noted right away that this device is not designed for an ordinary private gardener or summer resident, but for owners of large areas with green spaces. This is a gasoline unit with a 2-stroke engine with a power of 0.6 kW. Also, owners of the model note a spacious tank of 17 liters. However, this arrangement will not be convenient for everyone - you must understand that both the engine and the tank determine the considerable weight of the structure. But in terms of performance, the backpack sprayer in this design is one of the best representatives of its class. According to experienced users, the model is productive, functional and reliable. If spraying large areas is required, then this option will be optimal. However, it is important to take into account another nuance: greenhouse and greenhouse farms cannot be serviced by this model due to harmful emissions.
How to choose a suitable option?
To begin with, it is worth deciding on the requirements for the volume of release of the chemical. For a small area, 5-liter devices are quite suitable, which, if possible, can be retrofitted with regulators and devices for controlling flow. Medium-sized areas can be serviced by 10-12-liter units. This may be a domestic unit from the "Zhuk" family of pump-action type, and a representative of foreign garden equipment on the battery-powered swap principle. If the task is to work in fields or large areas, then a backpack sprayer with motor traction on gasoline is suitable. Such models, of course, have negative aspects of operation and not the best ergonomics, but they have no equal in performance indicators.
Conclusion
The presence of a garden sprayer on the farm is necessary for any caring and responsible summer resident. This tool will allow you to effectively maintain vegetation in a healthy state, timely eliminate and prevent disease processes and the spread of harmful insects. Compared to other devices that perform chemical spraying tasks, the knapsack sprayer features convenient operation, a simple fluid supply system and a lightweight design. At the same time, there are various modifications with various performance indicators, functionality and reliability. Although the basic principles for the development of this garden product have not changed for many years, in the latest versions, individual technological improvements are increasingly appearing. This includes the introduction of a chemical flow sensor, and effective filtration systems, as well as structural devices that contribute to more comfortable handling of the units.
