Description
Technical field
The present invention relates to a kind of sprayer, especially a kind of Self-walking sprayer with spraying rod, belongs to equipment for plant protection technical field.
Background technology
Pest control equipment operation effectiveness directly has influence on the Growth and yield of crop, once control not in time or control efficiency bad, will make crop failure.Boom sprayer is as a kind of important pest control equipment, and its application is increasingly extensive, is mainly used in the land for growing field crops extermination of disease and insect pest.Mainly there is following shortcoming in existing boom sprayer: function singleness, use face is narrow and float of mist droplet is serious.
Retrieval discovery, the Chinese patent application that application number is 201010132576.5 discloses a kind of spray bar type spraying machine, comprises and hangs assembly, plural spray boom air curtain assembly and liquid delivery assembly and air-supply assembly; Liquid delivery assembly is connected and communicates with flexible air curtain pipe with flexible joint nozzle separately respectively with air-supply assembly, to form spray area and the line-spacing of various shape, changes.Yet in fact, this technical scheme automaticity is low, can not automatically adjust for different tree-like and plant heights, cause agricultural chemicals not to be sprayed on target completely.
In addition; application number is that 200910312649.6 Chinese patent application discloses and a kind ofly can copy the fruit tree imitating precision spraying locomotive that fruit tree shape is sprayed; comprise motor vehicle; on motor-vehicle chassis, be provided with the fan supporting rod that is erected at tree crown one side, fan supporting rod is connected with driving the transverse shifting actuating unit of Qi Yan chassis transverse shifting; In fan supporting rod, be fixed with loop bar, in loop bar, be rotationally connected rotating guide; Rotating guide is connected with driving the revolving power mechanism of its rotation; For wrapping the top of cage tree crown and the profile modeling spray bar of opposite side is hinged on rotating guide, rotating guide is connected with the oscilaltion actuating unit that drives it around aforementioned pin joint swing; On fan supporting rod and profile modeling spray bar, be provided with to the fan of tree crown blowing, shower nozzle is set on fan; Shower nozzle is connected with the delivery tube that is in series with spray liquid medicine pump.Yet this technical scheme can only be carried out spraying operation to fruit tree, being not suitable for field crop (wheat, paddy rice etc.) and fruit tree is seedling operation, and function is more single.Experiment shows, when fruit tree is seedling, loop bar in its monosymmetric ∏Xing mechanism can not move up and down (can only adjust its left and right distance by the motion of rotating guide), therefore can not be applicable to the height of fruit tree seedling, the droplet producing to the sprayer unit that makes to be arranged in ∏Xing mechanism is lost in air in a large number; Due to its sprayer unit, be a kind of many nozzle structures of ring-type of provided with fan on the other hand, during operation, fan generation high velocity air drives droplet to travel forward, and seedling fruit tree leaf is less, canopy is thin, droplet under high velocity air drives only has a small amount of can being sprayed on canopy target, and great majority will be sprayed onto in ground and air.
Summary of the invention
The object of the invention is: provide a kind of droplet drift effect applied widely, anti-good, and control Self-walking sprayer with spraying rod easily.
In order to achieve the above object, boom sprayer of the present invention comprises the portal frame that is placed in motor-vehicle chassis rear end, the flusher framework that forms with it vertical moving sets is housed on described portal frame, and described flusher framework has the upper and lower horizontal beam rail being mutually connected; The middle part of described upper horizontal beam rail is connected with the piston rod upper end of vertical oil cylinder, described upper and lower horizontal beam Gui two ends form and move horizontally pair with left and right symmetrical upper and lower horizontal sliding bar respectively, described upper and lower horizontal sliding bar is fixedly connected with by vertical rod, and the middle part of described vertical rod is connected with the piston rod outer end of cross cylinder; The outer end of described upper horizontal sliding bar and the cylinder body of rotary oil cylinder are hinged, and the outer end of described lower horizontal sliding bar is hinged with the inner of distortion spray boom, and the piston rod overhanging end of described rotary oil cylinder and the middle part of described distortion spray boom are hinged; Horizontal spray boom under described lower horizontal beam rail and described distortion spray boom are equipped with nozzle spaced apart and can be towards the air bag of nozzle direction air-out, described nozzle is communicated with the medicine-chest infusion pump being placed on motor vehicle by woven hose, and described air bag is communicated with aerating device by conduit; When the piston of described rotary oil cylinder is during in retracted mode, described distortion spray boom is in stand up position; When the piston of described rotary oil cylinder is when stretching out state completely, described distortion spray boom is horizontal.
During use, not only the height of flusher and position, left and right all can regulate and control, and when needs spray differing heights crops such as fruit tree or seedling, distortion spray boom can be regulated arbitrarily between 0～90 ° of corner, therefore adaptability good, applied widely, control conveniently, and the air-flow of emitting by air bag can evenly be pushed the droplet of nozzle ejection to crop, and anti-droplet drift effect is good.
The present invention further improves, and on described horizontal spray boom and distortion spray boom, ultrasonic transmitter and ultrasonic sensor is housed, and the signal output part of described ultrasonic sensor connects respectively the controlled end of described each oil cylinder by control circuit.The present invention further improves, and between each nozzle of described horizontal spray boom and distortion spray boom, magnetic valve is housed, and the signal output part of described ultrasonic sensor also connects respectively the controlled end of described each magnetic valve by control circuit.Like this, not only can survey shower nozzle to the distance of crop according to supersonic sensing system, thereby by controlling oil cylinder, shower nozzle is adjusted to correct position automatically, can also spray by the segmentation of solenoid control spray boom, effectively guarantee that droplet is sprayed on target, significantly reduce the invalid drift of droplet, guarantee spray effect, save pesticide dosage, reduce environmental pollution.
