Description
Technical Field
The invention relates to a device for self-adapting concentration of agricultural irrigation water and biogas slurry.
Background
The biogas slurry is generally utilized as follows: the decomposed biogas slurry contains rich amino acids, auxins and mineral nutrient elements, wherein the total nitrogen content is 0.03-0.08%, the total phosphorus content is 0.02-0.07%, and the total potassium content is 0.05-1.4%, so that the decomposed biogas slurry is a good high-quality quick-acting fertilizer, and can be singly applied or mixed with chemical fertilizers, pesticides, growth agents and the like. Can be used as seed fertilizer, top dressing and foliage spraying fertilizer. The fertilizer is used as a fertilizer: the water quality of the biogas slurry ensures that crops can absorb the biogas slurry very quickly, and the biogas slurry has quick and slow effects. Researches show that the normal Shi Zhao liquid has strong crop growth, obviously increased leaf thickness and fruit weight, obviously improved quality, and can improve the yield by about 15-35%, and the average height of soluble sugar is 36%; has special effects on crop hypocrenia, such as lobular disease; meanwhile, the cold resistance physiology is improved, the frost resistance is improved, and the fertilizer is called as 'king in fertilizer', and is the best fertilizer for producing pollution-free green and high-grade organic foods, which has the most balanced nutrition for crops in the world at present. Used for seed soaking: seed soaking to improve germination rate; the biogas slurry after fermentation by the starter is used for seed soaking, so that the activity of enzymes in seeds can be stimulated, the division of embryo cells is promoted, the growth is stimulated, and the growth genes are regulated. Is used for preventing and treating plant diseases and insect pests: butyric acid in organic acid and gibberellin, indoleacetic acid, vitamin B12 and the like in plant growth hormone contained in the biogas slurry can destroy cell membranes and in-vivo proteins of single-cell germs, and effectively control the reproduction of harmful germs; de-ammonia, ammonium salt and antibiotics in the biogas slurry can inhibit and seal the respiratory system of diseases and insect pests such as red spiders, thereby achieving the effects of expelling parasites, killing insects and sterilizing. For fruit tree rot, ring rot, dry rot, root rot, alternaria leaf spot, moldy heart disease, brown spot, powdery mildew, black spot and red spot; pear scab; anthracnose and anthracnose of grape anthracnose; cherry leaf perforation disease, leaf spot disease, gummosis; almost all fungi and bacterial diseases such as epidemic disease, banded sclerotial blight and the like of fruit vegetables and field seedling stage have obvious control effect. Has remarkable control effect on almost all diseases and insect pests such as aphids, red spiders, white spiders, ground maggots, shirttail eggs, cabbage caterpillars, asparagus caterpillars, cotton bollworms and the like, and the number of the control times of the diseases and insect pests can be reduced (at least three times) for crops using biogas slurry all year round. And has no pollution, no residual toxicity and no drug resistance, and is called as biological pesticide. However, too high a concentration can lead to crop death, while too low a concentration is ineffective and therefore requires a means of controlling the concentration of biogas slurry to regulate.

a control module 10 is arranged on one side of the tubular motor 7; an electrode a8 is arranged at one end of the liquid mixing self-adaptive cavity 2, and an electrode b9 is arranged on the flexible latex film 12; the electrode a8 and the electrode b9 are connected into the control module 10; the tubular motor 7 is controlled by a control module 10; the outer wall of the telescopic shaft 11 is milled with threads, and the driving part of the tubular motor 7 is meshed with the threads on the outer wall of the telescopic shaft 11.
The outer wall of the telescopic shaft 11 is provided with length scale marks.
The flexible latex film 12 has a transverse deformation range of between 0 cm and 2.3 cm.
The irrigation water pipe 3 is communicated with the liquid mixing pipe 1 through a flexible joint 31.
The irrigation water pipe 3 is sleeved with a water pipe quick connector 32 at the top.
The voltage range of the electrode a8 and the electrode b9 is 6-24V.
The volume ratio of the liquid mixing pipe 1 to the liquid mixing self-adaptive cavity 2 is 1:3 to 1:5.7.
The distance between the electrode a8 and the electrode b9 is 5.5-11.2 cm.
The core of the invention is that: a flexible latex film 12 and electrodes a8 and b9 coupled to each other; the self-adaptive control principle is as follows: because electrode signals are generated between the electrode a8 and the electrode b9, when the concentration of biogas slurry in the mixed liquid self-adaptive cavity 2 is high, the resistance between the electrode a8 and the electrode b9 is small, so that the electrode signals between the electrode a8 and the electrode b9 are strong, the control module 10 can send a command to rotate the tubular motor 7, so that the telescopic shaft 11 is pulled outwards, the flexible latex film 12 can deform to one side in the pulling process because of a drawstring 13 drawknot between the telescopic shaft 11 and the flexible latex film 12, and the permeable holes 121 on the flexible latex film 12 can be closed and deformed due to the pulling in the deformation process of the flexible latex film 12, so that the permeable rate of the permeable holes 121 on the flexible latex film 12 can be reduced. Thereby realizing the reduction of the amount of the biogas slurry flowing to the liquid mixing pipe 1 in the liquid mixing self-adaptive cavity 2 and finally realizing the reduction of the concentration of the biogas slurry sprayed by the spraying head 6. On the contrary, when the concentration of the biogas slurry flowing into the mixed liquid self-adaptive cavity 2 in the biogas slurry water pipe 4 is low, the resistance between the electrode a8 and the electrode b9 is large, so that the control module 10 can command the tubular motor 7 to rotate in the opposite direction, the flexible latex film 12 is enabled to recover the state before deformation, the water permeable holes 121 are inevitably caused to be enlarged in the process, a large amount of biogas slurry flows into the mixed liquid pipe 1, and the concentration of the biogas slurry flowing out of the jet head 6 is improved.
