Embodiment:
The go-cart of Crops in Applying Fertilizer laxative, there is metal frame 12, wheel 1, be fixed with liquid manure case 11 on vehicle frame, the sprayer assembly is housed in the liquid manure case, the sprayer assembly is a kind of usual means of manual agricultural equipment, it mainly is comprised of water pumping cylinder and adjutage two parts, be equipped with in water pumping cylinder and suppress pump rod, suppress the end of pump rod in water pumping cylinder rubber tube plug or rubber ring are housed usually, the lower end of water pumping cylinder is provided with water inlet (also referred to as the water inlet of sprayer assembly), the upper end of adjutage is provided with the delivery port of delivery port 6(also referred to as the sprayer assembly), water pumping cylinder is communicated with water inlet and adjutage respectively by two relatively reverse check valves, when pump rod is suppressed in pull-up, the closed check valve of water pumping cylinder and adjutage, the check valve of water pumping cylinder and water inlet is opened, at this moment the water of liquid manure case is inhaled into water pumping cylinder, when when pressing down the pressuring pump bar, the closed check valve of water pumping cylinder and water inlet, the check valve of water pumping cylinder and adjutage is opened, at this moment the water of water pumping cylinder is sent to adjutage, the sprayer assembly is the parts commonly used in existing agricultural equipment, belong to prior art, here just it has not been further elaborated, by spraying hose 3, the shower nozzle 4 outer with the liquid manure case is connected the delivery port of described sprayer assembly, the pump rod 5 of suppressing of sprayer assembly is located at outside the liquid manure case, be provided with dog-house above the liquid manure case, case lid 10 is housed on dog-house, case lid and dog-house screw thread spin, be provided with discharging opening below the liquid manure case, the rubber that flexible connection is housed on discharging opening stops up 9, discharging opening is communicated with fertile mouthful of advancing of lower fertile box 13, be equipped with in lower fertile box and dial fertile wheel 15, dial fertile wheel and be one and there is the wheel-shaped body of equidistant radioactivity flange, be a space that storage is fertile between two adjacent ribs, fertilizer in the liquid manure case falls into the some storages fertile space corresponding with it by discharging opening, along with the rotation of dialling fertile wheel, fertilizer due to self gravitation from fertilizer outlet below fertile box drop out, realize quantitative fertilization, dialling fertile wheel is connected with the box body axis hole of lower fertile box, an end of dialling fertile wheel shaft 16 is placed in outside lower fertile box, and driven sprocket 18 and rocking arm 17 be housed, the end of rocking arm is equipped with the connecting rod 4 that axis hole connects, the other end of connecting rod is with to suppress pump rod hinged, flywheel 24 is housed on described axletree, flywheel links by chain 19 with driven sprocket, this structure can make go-cart when walking forward, allow flywheel pass through the rotation of chain-driving driven sprocket, driven sprocket drives the rocking arm rotation by dialling fertile wheel shaft, the connecting rod that is contained in the rocking arm other end is converted into upper and lower reciprocating motion by rotatablely moving of rocking arm, thereby drive the pump rod work of suppressing.
In order to improve the efficiency of laxative, spraying hose support 21 laterally is housed on vehicle frame, the spraying hose support can be across Duo Tiaolong, spraying hose is provided with several shower nozzles and can be gone and buy Chinese medicine to the multirow crops simultaneously, with manpower, went and buy Chinese medicine in the past, be subject to the restriction of manpower, the little speed of sprayer assembly pressure is slow, can not supply a plurality of shower nozzles is gone and buy Chinese medicine, adopt now the driving force that carriage wheel is sprayer, can adopt large sprayer assembly, recently to many shower nozzles, supply agricultural chemicals by the transmission of adjusting driven sprocket and flywheel, the spraying hose support is flexibly connected by adjustment rack 20 and vehicle frame, this is in order to be gone and buy Chinese medicine to the crops of different plant heights, so increased adjustment rack between spraying hose support and vehicle frame, adjustment rack in the present embodiment is to be welded with two corresponding pipes on vehicle frame, the spraying hose support is inserted in can be up and down in two pipes, have threaded hole on two pipes, bolt is housed in hole, fix the spraying hose support by screwing bolt, can realize that the mechanism that adjusts the spraying hose support height has much in the machine applications field, for example: some groups of hooks, hand push rod, self-locking folding arm frame etc., here do not narrated one by one yet, but the words that the spraying hose support is oversize, can make Crops in Applying Fertilizer laxative of the present invention go-cart very inconvenient when carrying out, so the two ends at the spraying hose support respectively are provided with hinged assistant support 22, spraying hose is connected on spraying hose support and assistant support by several pipe boxes 23, like this when not using spraying function or in when fertilising, assistant support is turned up up or down, spraying hose is also along with turning up, can save space, facilitate the peasant to use.
The fertilizing amount of different crops is also different, in order to address this problem, inventor's design is equipped with fertile amount regulating wheel 14 and hand rotary nut 26 at the other end of dialling fertile wheel shaft, fertile amount regulating wheel is slidably connected with group fertile wheel shaft, fertile amount regulating wheel is pegged graft with group fertile wheel, between fertile amount regulating wheel and group fertile wheel, spring 25 is housed, hand rotary nut spins with group fertile wheel male thread, hand rotary nut and fertile amount regulating wheel activity crimping, can control the fertile space of the storage of dialling fertile wheel shaft by the position of adjusting hand rotary nut, so can control fertilizing amount.
When laxative, the open auxiliary support, jam-pack rubber stops up, then the pesticide water of blending is poured in the liquid manure case, now promotes go-cart and walks forward, can be gone and buy Chinese medicine to crops; When fertilising, pull out rubber and stop up, fertilizer is poured in the liquid manure case, fold assistant support, after adjusting fertilizing amount by hand rotary nut according to actual needs, promote go-cart and walk forward, can be applied fertilizer to crops.
Crops in Applying Fertilizer laxative of the present invention go-cart is when going and buy Chinese medicine to crops, shower nozzle energy sustained firing, evenly without drain spray, spraying hose is located at the front end of go-cart, the peasant is in the rear end go-cart, and away from vaporific agricultural chemicals, the protection peasant's is healthy, alleviated the peasant people's labour intensity simultaneously, a plurality of shower nozzles can be set and increase work efficiency; To Crops in Applying Fertilizer the time, can control fertilizing amount, alleviated peasant's labour intensity, improved the operating efficiency of fertilising, laxative utensil and fertilizing equipment are carried out to combination, also reduced the cost that the peasant uses agricultural equipment, be convenient to the peasant simultaneously and transported.
