Application of weedicide (using multi-row weedicide sprayer) and foliar chemicals (using multi-row foliar chemical sprayer) separately in vineyard operation is commonly used. Although it is not an efficient option in terms of fixed, operational & maintenance cost, time spend for spraying and space required to park in idle time. Due to PTO and hydraulic connections, the tractor attached to weedicide or foliar chemical sprayers can't directly use for any other farm activates. Multi-row, foliar and weedicide combined, independent vineyard sprayer will provide the answer for these issues. The sprayer is built as one hitch wheeled trailer that can easily mounted (hooked) with drawbar of most of farm machineries. The sprayer comprises of 230V petrol operated electricity generator, 12V Pb-acid battery, 3000L - 5000L water storage, 200L weedicide and foliar chemical storage tanks (separate), 12V pressure pumps, flow control valves, two mechanically expandable arms, weedicide dispensing nozzle units, foliar chemical dispensing nozzle units fitted to high velocity electric fans and monitoring and controlling devices such as night vision cameras and three monitoring screens and controlling panel. With this sprayer, there is no need to mix weedicide or foliar chemicals with water. Both of them can be used as it is in 20L to 200L containers or they can be filled to 200L movable storage tanks; simply want to insert & secure liquid sucking tubes in to separate tanks. Flow control system will dispense at pre-set mixing ratio (water and chemicals) and volume through both weedicide and foliar application nozzles. Control panel is semi-wired device which is starting from the front of the sprayer and going to operating area. Both arms of the spryer are connected to mechanical (Figure 6) device that can control the arms and arm rest locking and unlocking mechanism. There are multiple adjustments to adjust arm lengths, nozzle heights and raw spacing to give wide range of flexibility. Weedicide and foliar chemical sprays can be carryout simultaneously (during both day and night) at pre-set rate and the sprayer-operator can monitor spraying progress with live monitors and flow meters in the control panel. The sprayer can be used as solo sprayer of weedicide or foliar chemical sprayer. When it uses for only foliar chemical application, weedicide dispensing nozzle units can be bend and store (Figure 5) in secure position. Cleaning of sprayer after use is safer and easy: need to remove & store remaining chemicals with 200L tanks in safe place or need to wash & clean 200L movable tanks. So there is minimum chance to contamination with previously used chemicals. |
