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-type paddy field inter-seedling weeder 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 purpose of the invention is realized as follows: a water pump, a direct current motor and a mounting frame are respectively arranged on the rear side part of the self-propelled power chassis, the water pump is connected with the direct current motor, a water delivery main pipe is arranged on the mounting frame, a water inlet and a water outlet of the water pump are respectively communicated with the water suction pipe and the water delivery main pipe, a filtering net cover is arranged on the end part of a water suction port of the water suction pipe, a five-way valve is assembled on the water delivery main pipe, the water inlet of the five-way valve is communicated with the water outlet of the water delivery main pipe, two front jet needle tubes and two rear jet needle tubes are respectively arranged on four water outlets of the five-way valve, two preceding efflux needle tubes be mutual symmetrical arrangement, two back efflux needle tubes be mutual symmetrical arrangement, the efflux end of preceding efflux needle tube is located the terminal front side top of back efflux needle tube efflux, the horizontal interval size H between two preceding efflux needle tube efflux ends.13-5 cm, the horizontal distance H between the jet ends of the two back jet needle tubes2The distance is 6-8 cm, and a storage battery assembled on the self-propelled power chassis is communicated with a direct current motor through a lead, so that the jet-type paddy field inter-seedling weeding machine is formed.
The invention adopts the liquid jet technology, finishes the operation of removing the weeds among seedlings by flushing the soil around the roots of the weeds among paddy field seedlings together with the roots of the weeds, has the characteristics of reasonable and simple structure, good weeding effect among paddy field seedlings, high operation efficiency, low seedling injury rate, reliable use, strong applicability, and adaptation and satisfaction of the production requirement of green organic rice products, and the spraying position and the spraying force of the liquid jet technology can not influence and damage the stability of the soil layer around the roots of the paddy field seedlings.

Detailed Description
The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings. A jet-type paddy field inter-seedling weeding machine comprises a self-propelled power chassis 1, wherein a water pump 7, a direct-current motor 8 and a mounting frame 4 are respectively arranged on the rear side part of the self-propelled power chassis 1, the water pump 7 is connected with the direct-current motor 8, a water delivery main pipe 9 is arranged on the mounting frame 4, a water inlet and a water outlet of the water pump 7 are respectively communicated with a water suction pipe 3 and the water delivery main pipe 9, a filter screen 2 is arranged on the end part of a water suction opening of the water suction pipe 3, a five-way valve 10 is assembled on the water delivery main pipe 9, the water inlet of the five-way valve 10 is communicated with the water outlet of the water delivery main pipe 9, two front jet needle tubes 5 and two rear jet needle tubes 6 are respectively arranged on four water outlets of the five-way valve 10, the two front jet needle tubes 5 are symmetrically arranged, the two rear jet needle tubes 6 are symmetrically arranged, and the jet ends of the front jet needle tubes 5 are positioned, horizontal spacing dimension H between the jet ends of two front jet needle tubes 513-5 cm, the horizontal distance H between the ends of the 6 jet flows of the two back jet flow needle tubes2The length of the wire is 6-8 cm, and the storage battery 11 assembled on the self-propelled power chassis 1 is communicated with the direct current motor 8 through the wire.
When the self-propelled power chassis 1 moves forwards, two front jet needle tubes 5 and two rear jet needle tubes 6 which are symmetrically arranged are respectively arranged at two sides of a paddy field seedling belt, wherein the horizontal distance between the jet tail end of the front jet needle tube 5 at one side and a paddy seedling is 1.5-2.5 cm, the depth of the front jet needle tube penetrating into soil is 2-3 cm, the horizontal distance between the jet tail end of the rear jet needle tube 6 at one side and the paddy seedling is 3-4 cm, the depth of the rear jet needle tube penetrating into the soil is 4-5 cm, the filter screen cover 2 is arranged in a water body of a paddy field, the storage battery 11 is utilized to start the direct current motor 8 to drive the water pump 7 to rotate, the water body of the paddy field is sprayed to the soil around weeds through the nozzle at the tail ends of the front jet needle tubes 5 and the rear jet needle tubes 6 respectively, the first spraying is performed through the narrower and shallower of the front jet needle tubes 5, and the first spraying is performed through the wider and shallower of the, And the deeper second spraying flushes the soil around the root system of the weeds among the seedlings together with the root system of the weeds, so that the root system of the weeds is separated from the contact with the soil in the paddy field, and the weeds float on the water surface of the paddy field to finish the weeding operation. 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 weeds in the paddy field and the conditions of the paddy field, different water pressure jet forces can be determined, and the seedling protection effect is ensured while the weeding effect is ensured.
