Rice transplanter-mounted liquid reagent application device, and method of applying liquid reagent during rice planting using same

Abstract

A device for distributing and discharging a liquid reagent provided. The device comprise a tank (10) storing the liquid reagent; a pump (12) draws the liquid reagent from the tank (10); a pipeline connected to the pump (12) to carry the liquid reagent drawn by the pump (12); a distribution unit (20) connected to the pipeline (16) to distribute and discharge the liquid reagent carried by the pipeline (16); and a mechanism that receives the liquid reagent carried by the pipeline (14) and captures air contained in the received liquid reagent. A method of applying a liquid reagent to control pests, fungi, and / or weeds during rice planting using the device for distributing and discharging a liquid reagent. The method comprising: applying the liquid reagent though the distribution unit (20) and into one or more spaces between a plurality of hilling in which seeding are planted.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims the priority of the prior Chinese patent application No. CN201210064117.7, entitled "Transplanter Mounted Liquid Agent Spreading Device", filed on March 12, 2012, the entire contents of which are incorporated by reference this manual. field of invention [0003] The present invention generally relates to a device for dispensing and discharging liquid agents. More specifically, the present invention relates to a liquid agent application device mounted on a rice transplanter, and a method of applying the liquid agent using the device while transplanting rice. Background technique [0004] For the purpose of weeding, etc., the operation of spraying pesticides at the same time as rice transplanting operations, that is, so-called pest control, involves applying pesticides at the same time as rice transplanting, thereby saving labor; the chemical spraying device mounted on the rice t...

Problems solved by technology

In the case of conventional granule spraying devices, depending on the strength or angle of dispersal of granules, some granules were buried in the paddy field soil, which meant that the effect of the granules was not exerted, resulting in unsatisfactory coverage in some areas. Weeding effect

On the other hand, granules close to the transplanted seedlings will cause phytotoxicity to the seedlings

Granular dispensers are also susceptible to weather conditions such as rainfall and wind

Rainfall is not good as it causes sticking of the granules to the machine

In addition, due to the heavy weight and bulky size of the granules, it is difficult to spread a mixture of several granules if there is no supply of granules during the transplanting process.

Mixing of granules with different relative densities is also undesirable, as this does not allow for uniform spreading of the granules

In addition, conventional liquid agent spraying devices are usually mounted on 6-row to 8-row rice transplanters, but since the liquid agent is only dripped between the central ridges (that is, dripping an intra-row space dripping), therefore The liquid agent cannot spread in all the ridges of 6 to 8 rows, which means that the control effect cannot be obtained evenly

Especially in the case where the field where the rice is transplanted is in a shallow water state, if a uniform depth of immersion cannot be achieved, or when the state of immersion cannot be immediately formed after simultaneous transplanting and treatment, the active ingredient of the drug cannot be sufficiently diffused, so it cannot Achieve desired effects such as weed control, pest control or fungal disease control

In addition, the uneven spreading of pesticides will also promote the phytotoxicity of rice.
