Description
Technical Field
The utility model relates to an unmanned aerial vehicle plant protection, in particular to liquid medicine supply pipeline in unmanned aerial vehicle plant protection belongs to unmanned aerial vehicle plant protection technical field.
Background
Unmanned aerial vehicle agricultural plant protection develops rapidly in recent years, for example oil moves unmanned aerial vehicle operation every day and can surpass 1000 mu, and its dosage is 80% that traditional applied medicine, adopts the atomizing to spray, and the water consumption reduces more than 90%, is higher than manual work efficiency greatly, provides reliable realization way for high-efficient accurate agriculture. The prior unmanned plant protection machine generally adopts two pesticide barrels fixed on two sides of a machine body, the pesticide barrels supply pesticide to spray heads through liquid supply pipelines, the liquid supply pipelines are divided into a front pump pipeline and a rear pump pipeline, the front pump pipeline is connected to an inlet of a liquid pump from the two pesticide barrels through plastic pipes, an outlet of the liquid pump is connected to each spray head through the plastic pipes, when spraying is carried out, the liquid pump supplies liquid to the spray heads according to set spraying amount, in this way, the pesticide barrels are fixed on the unmanned aerial vehicle, when the pesticide liquid is exhausted and needs to be replenished, the pesticide liquid can only be prepared in the pesticide barrels after the unmanned aerial vehicle descends, so the flight time of the unmanned aerial vehicle is influenced by the way, the operation efficiency of the unmanned aerial vehicle plant protection is reduced, if the pesticide liquid is directly prepared in the pesticide barrels, then the pesticide barrels are replaced quickly, the liquid replenishing time can be reduced, the operation efficiency is improved, but the pipelines connected with the two pesticide, it can not be two completely synchronous to change the explosive barrel, if install an explosive barrel earlier, the liquid medicine can be followed the kneck outflow of another explosive barrel and caused waste and environmental pollution, and this is not allowed in spraying the pesticide, so under the condition of changing the explosive barrel fluid infusion, need one kind can be from the supply pipeline of closed interface.
Disclosure of Invention
The utility model discloses an aim at satisfying the requirement that plant protection unmanned aerial vehicle changed the explosive barrel fluid infusion, provide an unmanned plant protection machine from closed joint liquid supply pipeline.
In order to realize the purpose of the utility model, the following technical proposal is adopted: unmanned plant protection machine is from sealing interface liquid supply pipeline, pipeline before the pump, the pump in the pipeline before in order to connect two explosive barrels through a tee bend, a liquid pump is connected to a port of tee bend, a branch pipe is connected respectively to two other ports of tee bend, the branch connection on the disk seat, install on the disk seat and press open-type elasticity and proclaim oneself the valve.
Further, the method comprises the following steps of; the press-open type elastic self-sealing valve comprises a flow channel, a support is fixedly connected in the flow channel, a valve rod penetrates through a hole in the support in a sliding mode, a diaphragm is fixedly mounted at the lower end of the valve rod, a step is arranged on the upper portion of the valve rod, a spring is arranged between the step and the support in a propping mode, and the spring props against the valve rod to enable the diaphragm to close the flow channel in a natural state.
The utility model discloses an actively beneficial technological effect lies in: this liquid supply pipeline accessible presses open-type elasticity from sealing valve self-sealing runner when not having the explosive barrel, can not emerge from the opposite side after adorning an explosive barrel, can satisfy the requirement of changing the explosive barrel, also can prevent debris entering pipeline when not having the explosive barrel in addition, keeps the pipeline unblocked.

Detailed Description
In order to explain the utility model more fully, the utility model provides an implementation example. These examples are merely illustrative of the present invention and do not limit the scope of the present invention.
The invention is explained in further detail with reference to the drawings, in which the reference symbols are: 1: a liquid pump; 2: a branch pipe A; 3: a valve seat A; 4: a branch pipe B; 5: a valve seat B; 301: a flow channel; 302: a support; 303: a membrane; 304: a valve stem; 305: a spring.
As shown in the attached drawings, the self-sealing interface liquid supply pipeline of the unmanned plant protection machine comprises a front pump pipeline, wherein 1 in the figure is a liquid pump, the front pump pipeline is connected with two medicine barrels through a tee joint, one port of the tee joint is connected with the liquid pump, the other two ports of the tee joint are respectively connected with a branch pipe, and the two branch pipes in the figure are respectively a branch pipe A2 and a branch pipe B4; the branch pipe is connected to the valve seat, the branch pipe A is connected to the valve seat A3, the branch pipe B is connected to the valve seat B5, and the valve seat is provided with a press-open type elastic self-sealing valve. The utility model discloses a press open-type elasticity from valve of proclaiming oneself indicates under the condition of exerting pressing force, and the valve can be opened, loses the pressing force after, valve self-closing, and this kind of valve can adopt present push type tap's structure. The press-open type elastic self-sealing valve can be realized by adopting the existing valve with a press-water-outlet type faucet structure.
In this application specifically, use the pressing open-type elasticity on the disk seat A to proclaim oneself the valve as the example, pressing open-type elasticity proclaim oneself the valve and including runner 301, fixedly connected with support 302 in the runner, during valve rod 304 slides and wears to establish the hole on the support, valve rod lower extreme fixed mounting has diaphragm 303, valve rod upper portion have the step, the top is equipped with spring 305 between step and support, under the natural state, the spring is pushing up the valve rod and is making the diaphragm seal the runner. When the valve rod is pressed downwards in the figure 2, the diaphragm loses the sealing effect of the convection channel, and after the valve rod is released, the diaphragm can naturally seal the convection channel under the action of the spring.
After the embodiments of the present invention have been described in detail, those skilled in the art can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above claims, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention all fall within the scope of the technical solution of the present invention, and the present invention is not limited to the embodiments of the examples given in the specification.
