Description

Anti-blocking sprayer Technical field: the utility model belongs to the technical field of sprayers, and particularly relates to an anti-blocking sprayer. The background technology is as follows: In the fields of agricultural plant protection, industrial cleaning, sanitation and epidemic prevention and the like, the sprayer is a key device for realizing liquid atomization operation. A single-layer or multi-layer filter screen is arranged inside the traditional sprayer and is generally used for intercepting particle impurities in liquid medicine so as to reduce the risk of nozzle blockage. But under high impurity load environment such as orchard weeding, industrial sewage sprays, the filter plate very easily is covered by impurity, leads to the jam of filter, makes the liquid medicine pass through filter speed decline or unable filter, needs the operation personnel to stop the operation to the clearance of filter, and the filter screen is dismantled in the shut down of every clearance needs, makes the operating time increase, influences operating efficiency, needs to improve. The invention comprises the following steps: the utility model aims to provide an anti-blocking sprayer so as to solve the technical problems in the prior art. The utility model is realized in the following way: The anti-blocking sprayer comprises a medicine box, a spray rod, a spray head, a pumping unit and a filtering unit, wherein liquid medicine enters the pumping unit after being filtered by the filtering unit, the pumping unit is used for conveying the liquid medicine in the medicine box to the spray rod, a liquid cavity is formed in the medicine box, the filtering unit divides the liquid cavity into a liquid inlet cavity and a liquid outlet cavity, the liquid medicine flows into the liquid outlet cavity from the liquid inlet cavity, the filtering unit comprises a filter plate arranged in the medicine box, a filling unit arranged in the medicine box and a collecting box connected onto the medicine box in a sliding manner, the distribution direction of the filter plate and the filling unit is parallel to the sliding direction of the collecting box, a collecting cavity and a liquid inlet channel are formed in the collecting box, when the collecting box moves to the filling unit, the filling unit is filled in the collecting cavity and the liquid inlet channel, when the collecting box moves to the filter plate, the collecting cavity is positioned on one side close to the liquid inlet cavity, the collecting box is positioned on one side close to the filter plate, the liquid inlet channel is positioned on one side close to the medicine box, and the collecting box is driven to the liquid outlet channel. Through adopting above-mentioned technical scheme, in the operation process, the pumping unit work, liquid medicine in the feed liquor chamber gets into out the liquid intracavity after filtering through the filter, impurity is located the one side that the filter is close to the feed liquor chamber, when impurity cover filter, driving piece drive collecting box is to the direction removal that is close to the filter, make the filter get into in the collecting box, liquid medicine in the feed liquor chamber flows into the feed liquor passageway from the clearance between feed liquor passageway and the filling unit, get into the collecting chamber after flowing through the filter along the feed liquor, in the in-process that liquid medicine got into the collecting chamber, the impurity that the liquid medicine will cover on the filter is washed away the filter, make impurity suspension in the collecting chamber, driving piece drive collecting box is to the direction removal that is close to the filling unit, make filling unit refill collecting chamber and feed liquor passageway. Through removing the collecting box, borrow the liquid medicine to wash away the impurity on the filter backward, prevent that the filter from blockking up to this process need not to shut down the operation, is favorable to improving the operating efficiency. Preferably, the filter plates and the filling units are vertically distributed, and the filter plates are located below the filling units. By adopting the technical scheme, the filter plate is arranged below the filling unit, so that the filter plate can play a role in filtering even at a low liquid level. Preferably, a sliding opening for the filter plate to be clamped in is formed in the collecting box, and the sliding opening is attached to the surface of the filter plate. Through adopting above-mentioned technical scheme, laminating filter surface through the mouth that slides, when driving piece drive collecting box moved to filter department, can scrape the impurity part of filter surface cover, be favorable to reducing and collect intracavity impurity, reduce when the filtration pore that leads to the liquid medicine to leave the collecting box through the filter because of collecting intracavity impur
