At present, when vegetable farmers spray pesticides in greenhouses to reduce pests and diseases, many vegetable farmers buy push-type automatic sprayers. However, due to the high price of such sprayers, the general brand of push-type automatic sprayers are More than 1,000 yuan, this makes many farmers stop. Under this circumstance, vegetable farmer Song Aijiang of Songsi Village, Datian Township, Shouguang City, assembled and improved his knapsack electric sprayer and a small cart for picking cucumbers, forming a dual-use machine that can be used for spraying and picking vegetables. The cost is only around 600 yuan.
First, use a thin steel pipe with a diameter of about 4 cm to weld into the base of a small car. The width is determined by the width of the canal inside the shed. Generally, the width is narrower than the width of the canal by 30 to 40 cm. The length depends on the specific conditions. It is generally longer than the length of the vegetable basket.
Secondly, four wheels are mounted on the base of the trolley, that is, square steel pipes with a length of about 5 cm and a length of 2.5-3 cm are vertically welded on the four corners of the base as fixed sockets, and the two sides of the socket are marked with symmetry. The hole facilitates the fixation of the iron frame in the future. In addition, the bottom end of the socket is also welded with a piece of iron, and a push-pull handle is installed at one end of the base.
Again, use a square steel tube with a slightly shorter outer edge than the inner edge of the fixed socket to weld the upper and lower two-tier iron frame, and install the automatic hose reel on the end of the iron frame near the handle, and then insert the iron frame into the socket (frame insertion The part of the jack must also be punched so that it can be inserted and fixed later with a thin wire).
In this way, a multi-purpose machine was initially completed. Just when spraying, it is necessary to put a piece of wood on the second floor of the iron frame, and then put a big bucket with a valve on the bottom as a dispensing pail, and place an electric sprayer on the base of the car. Pressure difference generated at different heights, the medicine inside the bucket is hydraulically pressurized into the sprayer, and the sprayer is connected to the spray hose of the automatic hose reeler for spraying. However, farmers should be reminded that because the self-made spray device does not have a return pipe, liquid may not be agitated for a long period of time. Precipitation may occur during the spraying process. The vegetable grower should pay attention to constantly stirring the liquid in the barrel.
In addition, when irrigating with water, the bucket can be used as a device for dissolving the fertilizer. When the water is poured, the valve is opened so that the fertilizer solution can flow into the drain; and when the dish is picked, the iron frame, sprayer, etc. can be added. Take away, put the basket on the car to pick vegetables, is really a multi-purpose.
