Simple fertilizer-pesticide quantitative flushing applicator

Abstract

The invention relates to a simple liquid fertilizer-pesticide quantitative flushing applicator, which belongs to the field of flushing fertilizing tools. The flushing applicator consists of a liquid storage barrel, a liquid surface stabilizing bottle, a suspended type bracket, a display flow switch, a liquid disperser and a calling device, and is characterized in that the liquid storage barrel and the liquid surface stabilizing bottle form a uniform speed liquid supply liquid reservoir which can stabilize the liquid surface height of output liquid, fertilizes a fertilizer-pesticide solution with certain concentration to an earth furrow, a furrow opening or a drip-irrigation sprinkling-irrigation irrigation pipeline at a uniform speed according to certain flow, and realizes quantitative flushing application of a fertilizer and a pesticide along with water according to the time needed for irrigating a unit area of land by using a formula of 'fertilizer (pesticide) application quantity of a unit area of land = fertilizer (pesticide) liquid concentration * fertilizer (pesticide) liquid flow * time needed for irrigating a unit area of land'. The flushing applicator has the advantages of simple structure, convenient use and wide application range, and can be hung on a bicycle to move conveniently and quickly.

Description

1. Technical field [0001] The invention relates to a device for quantitatively flushing liquid fertilizer and pesticide or fertilizer and pesticide solution along with irrigation water, and belongs to the field of flushing fertilization tools. 2. Background technology [0002] In terms of rhizosphere topdressing, the conventional fertilization method of farmers is to spread the fertilizer on the field first, and then irrigate. This method is often because the fertilizer cannot be watered in time, and the volatilization loss of the fertilizer is serious; it is very inconvenient to spread the fertilizer when the plants are taller; [0003] The conventional method of fertilization by farmers is to use a liquid storage tank to store liquid fertilizer, and then use a siphon to guide the fertilizer liquid into the furrow. The fertilizer liquid flows with the water and mixed with irrigation water, and then applied to the field. The problem that this method exists is that along wit...

AI Technical Summary

Problems solved by technology

The problem with this method is that with the reduction of the fertilizer liquid in the liquid storage tank, the liquid level of the liquid storage tank decreases, the pressure of the output fertilizer liquid decreases, the flow rate becomes smaller, the flow rate decreases, the fertilization is uneven, and it is difficult to achieve quantitative fertilization.

The disadvantages are: ①The use of floating valve ball control is prone to failure, and the controlled liquid level fluctuates greatly; ②The fertilizer supply speed is difficult to meet the needs of diversity

[0005] The utility model patent "Water Flush Applicator" issued on May 5, 2004 with the authorization announcement number CN 2613981Y provides a better solution, but there are some deficiencies: 1. it is only suitable for absorbing water with a water pump The irrigation method and ditch irrigation are limited; ②The amount of fertilization can be controlled, but it is difficult to do quantitative fertilization due to different situations in operation;

The disadvantages are: ①The inhaled fertilizer ratio is inconvenient to adjust, and it is difficult to adapt to the diversity of fertilizer needs; ②It is suitable for pipeline irrigation and water pump irrigation, and ditch irrigation is limited

But it has the following disadvantages: ①Complicated structure, with a frame, a fertilizer tank with agitator, a diesel engine unit, a micro pump, and even a manual pump for the siphon effect; ②High cost; ③Ditch There needs to be a water level difference of 20-30cm between the bottom and the furrow surface to use the "Surface Irrigation Fine Flushing Apparatus"; therefore, its use is limited by conditions;

Its disadvantage is that the structure is still relatively complicated, and it must be connected to the irrigation pipeline when it is used. Its use is limited by conditions and it is not convenient for ditch irrigation.
