Description

Sprayer for spraying liquid probiotics

Technical Field

The utility model relates to an agricultural spraying technical field, concretely relates to a atomizer for spraying liquid probiotic.

Background

Tobacco is an important economic crop, and the soil fertility and the structure of a tobacco planting area are poor due to long-term use of pesticides and fertilizers and single crop planting, so that soil-borne diseases occur sometimes, and the quality and the yield of tobacco leaves are seriously influenced. The beneficial microbial preparation can improve the crop yield, prevent and control plant diseases and improve the soil environment, wherein the rhizosphere growth-promoting bacteria can live in the rhizosphere circle of the crops with nutrient substances, secrete active substances to directly or indirectly promote the absorption of plant nutrients and the prevention and control of the diseases, and have important application value.

The well cellar type seedling transplanting technology is a cultivation mode for transplanting flue-cured tobacco seedlings into a well cellar with a certain specification to realize strong seedling cultivation, timely early cultivation and high-ridge deep cultivation of flue-cured tobacco, so that the flue-cured tobacco seedlings grow robustly. Before well cellar sealing, the growth-promoting rhizobacteria is sprayed to the rhizosphere of tobacco seedlings, which is beneficial to rhizosphere colonization and achieves better growth-promoting effect. The prior fertilizer (liquid fertilizer) applied before the sealing and filling of the tobacco seedling well is mainly applied by pipeline, the water is fast to flow out, the substrate at the root of the tender seedling or the trace elements contained in the soil are easily washed off, the growth of the tender seedling is not facilitated, the liquid flows out concentratedly and cannot be uniformly applied to the root, and the colonization of rhizosphere growth-promoting bacteria at the root is not facilitated. For example, in the "agricultural hole-defining fertilizer applicator" disclosed in chinese patent document CN216362545U, the fertilizer is applied by using the spraying pipe, and due to the gravity, the liquid fertilizer is spread from the fertilizer can 4 to the lower end of the spraying pipe and the speed is high, so that the trace elements in the soil or the matrix at the root of the seedling is easily dispersed, and the fertilizer at the spraying pipe is concentrated (i.e., the fertilizer is concentrated in the soil corresponding to the pipe orifice of the spraying pipe), the diffusion is slow, and the local over-nutrition of the soil is easily caused; in addition, the device can't be in the fertilization in-process, carry out the flow control of the inside liquid fertilizer of spray line to cause fertilizer extravagant, the problem that nutrition is too flourishing, burn root and burn seedling appears even.

The working principle is as follows:

when the sprayer is used, firstly, the sprayer 100 is moved to a position to be sprayed by a moving mechanism (the existing common moving mechanism can be adopted, such as a moving trolley and the like), then the liquid fertilizer (or the liquid probiotics) is introduced into the guide pipe 202 by the pump body of the liquid fertilizer (or the liquid probiotics) storage device, and the liquid fertilizer (or the liquid probiotics) enters the spraying pipeline 10 from the guide pipe 202 and the through hole 71 and is blocked at the large-diameter section of the spraying pipeline 10 by the sealing plate 30. Then, the lifting plate 200 is started to move downwards through a conventional lifting mechanism, the lifting plate 200 moves downwards to drive the sprayer 100 and the motor 300 to move downwards together, when the contact head 61 of the sprayer 100 is in contact with soil on the ground, the sealing plate 30 is pushed by the supporting force of the soil, so that a gap is formed between the sealing plate 30 and the spray pipeline 10, and the liquid fertilizer (or liquid probiotics) on the sealing plate 30 flows into the small-diameter section of the spray pipeline 10 from the gap and enters the soil through the gap between the sliding blocks 41, the discharge hole 511, the adjusting hole 521, the first flow channel hole 21, the cavity 23 and the second flow channel hole 22, and is uniformly sprayed into holes of the soil. The adjustment of the upward movement distance of the sealing plate 30 can be achieved by adjusting the upward movement distance of the contact 61, thereby achieving the first adjustment of the flow rate. Meanwhile, the motor 300 can be controlled to rotate, so that the spraying pipeline 10 is driven to rotate through the driving gear 301 and the driven gear 101, and the drainage plate 51 and the rotating plate 52 rotate relatively (friction teeth can be arranged on the bottom surface of the contact 61 to increase friction between the contact 61 and soil, so that the contact 61 and the second connecting rod 60 are prevented from rotating in the rotating process of the spraying pipeline 10), and the second adjustment of the flow rate is realized by adjusting the contact ratio between the drainage hole 511 and the adjusting hole 521.
