Traditional paddy field weeding mostly adopts a chemical agent weeding mode. In recent years, with the development of green organic agriculture, China puts forward 'three-reduction' requirements on the use of chemical fertilizers, pesticides and chemical herbicides, and the development trend is 'three-free'. Accordingly, mechanical weeding machines for paddy field weeding operation under paddy field conditions have been developed, but due to the particularity of the paddy field conditions, the mechanical weeding machines for paddy fields have high seedling injury rate and poor operation effect, cannot meet the requirements of paddy field weeding operation, particularly have poor clearing effect on paddy field inter-seedling weeds, and cannot be used in paddy field weeding operation.
Disclosure of Invention
The invention aims to solve the problems in the prior art, particularly to research and design a jet flow type paddy field inter-seedling weeding monomer by combining with the actual requirements of paddy field inter-seedling weeding operation, so as to achieve the purposes of good inter-seedling weeding effect, high efficiency, low seedling injury rate, no drug residue and meeting the production requirements of green organic rice products.
The invention aims to realize the purpose that a filter screen cover is assembled at the water inlet end of a water suction pipe, the water outlet end of the water suction pipe is connected with the water inlet of a water pump assembled with a direct current motor, the water outlet of the water pump is connected with the water inlet end of a water delivery main pipe with a water pressure gauge, the water inlet of a five-way valve is connected with the water outlet end of the water delivery main pipe, the water inlet ends of four water delivery branch pipes are respectively connected with four water outlets of the five-way valve, two front jet needle pipes and two rear jet needle pipes are respectively installed at the water outlet ends of the four water delivery branch pipes through four reducing joints, the two front jet needle pipes are symmetrically configured with each other, the jet ends of the two front jet needle pipes are respectively positioned above the front sides of the jet ends of the two rear jet needle pipes, and the horizontal space size H between the jet ends of the two front jet needle13-5 cm, the horizontal distance H between the jet ends of the two back jet needle tubes2The width of the guide wire is 6-8 cm, and the storage battery is communicated with the direct current motor, so that the jet flow type paddy field inter-seedling weeding monomer is formed.
The invention adopts the liquid jet technology to complete the operation of removing the weeds among seedlings by flushing the soil around the roots of the weeds among paddy seedlings together with the roots of the weeds, the spraying position and the spraying force of the liquid jet technology cannot influence and damage the stability of the soil layer around the roots of the paddy seedlings, and the liquid jet technology has the characteristics of simple and reasonable structure, good weeding effect among paddy seedlings, high efficiency, low seedling injury rate, reliable use, and suitability for and satisfaction of the production requirements of green organic paddy products.

Detailed Description
The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings. A jet flow type paddy field inter-seedling weeding monomer, wherein a water inlet end of a water suction pipe 2 is provided with a filtering net cover 1, the water outlet end of the water suction pipe 2 is connected with the water inlet of a water pump 3 provided with a direct current motor 4, the water outlet of the water pump 3 is connected with the water inlet end of a water delivery main pipe 6 provided with a water pressure gauge 5, the water inlet of a five-way valve 7 is connected with the water outlet end of the water delivery main pipe 6, the water inlet ends of four water delivery branch pipes 8 are respectively connected with four water outlets of the five-way valve 7, two front jet needle tubes 10 and two rear jet needle tubes 11 are respectively arranged on the water outlet ends of the four water delivery branch pipes 8 through four reducing joints 9, the two front jet needle tubes 10 are symmetrically arranged, the two rear jet needle tubes 11 are symmetrically arranged, the jet tail ends of the two front jet needle tubes 10 are respectively positioned above the front sides of the jet tail ends of the two rear jet needle tubes 11, and the horizontal distance H between the jet tail ends of the two front jet needle tubes 10 is formed.13-5 cm, the horizontal distance H between the jet ends of the two back jet needle tubes 112The length of the lead is 6-8 cm, and the storage battery 12 is communicated with the direct current motor 4 through the lead.
When the weeding monomer is used for operation, the weeding monomer is assembled on a weeding machine between paddy seedlings to randomly move forwards, two front jet needle tubes 10 and two rear jet needle tubes 11 which are symmetrically arranged are respectively arranged at two sides of a paddy seedling zone, wherein the horizontal distance between the jet end of the front jet needle tube 10 at one side and the paddy seedling is 1.5-2.5 cm, the depth of the front jet needle tube 10 penetrating into the soil is 2-3 cm, the horizontal distance between the jet end of the rear jet needle tube 11 at one side and the paddy seedling is 3-4 cm, the depth of the rear jet needle tube 11 penetrating into the soil is 4-5 cm, a filter screen cover 1 is arranged in water, a direct current motor 4 is started by a storage battery 12 to drive a water pump 3 to rotate, the water passes through the filter screen cover 1, a water suction pipe 2, the water pump 3, a water conveying main pipe 6, a five-way valve 7, a water conveying branch pipe 8 and a reducing joint 9 and is respectively sprayed to the soil around the weeds from the front, The soil around the root system of the weeds among seedlings and the root system of the weeds are flushed together through the first spraying and flushing which is shallower and the second spraying and flushing which is wider and deeper through the rear jet needle tube 11, so that the root system of the weeds is separated from the contact with the soil of the paddy field, the weeds float on the water surface of the paddy field, and the weeding operation is completed. Based on the difference of rice seedling root system and weeds root system, above-mentioned jet force and injection position can not influence and destroy the steadiness of rice seedling root system. According to the difference of the growth condition of the grass among seedlings in the paddy field and the conditions of the paddy field, different water pressure jet forces can be determined through the water pressure meter 5, and the seedling protection effect is ensured while the weeding effect is ensured.
