The invention uses butane fuel as power and utilizes the air pressure generated by explosion of air-fuel mixture in a sealed space to emit seeds. The energy density of butane gas is higher than that of compressed air, so that the problem of short endurance of compressed air can be solved, and high-pressure gas generated by explosion can shoot seeds into the ground to a depth of tens of centimeters. The seed is emitted by high-pressure gas generated by explosion of butane fuel in a limited airtight space, and the cruising ability of the seeding system is improved by utilizing the characteristic of high energy density of butane gas. The kinetic energy emitted by each seed is provided by the energy generated by each explosion in the combustion chamber, so that the seeds can be shot into the ground to a certain depth, and the problem of deep sowing is solved.
Butane is used as a power source, so that the carbon emission can be greatly reduced for the following reasons; when the compressed air is prepared, firstly, the energy of fossil fuel is converted into mechanical energy by using an internal combustion engine, then, the mechanical energy is converted into the internal energy of the compressed air, and when the seeds are emitted, the energy of the compressed air is converted into the kinetic energy of the seeds, so that in the process, each link has energy loss, and the energy utilization efficiency of the method is low. And butane is directly used as fuel to emit seeds, so that the energy loss in the process can be avoided, the energy utilization efficiency is improved, and the carbon emission is greatly reduced.

In the invention, under the control of a control system program, under the control of an electromagnetic coil, the electromagnetic valve is sucked up (in the power-off state, the electromagnetic valve pushes the upper end of the electromagnetic valve against the inlet of the pressure stabilizing chamber under the action of the electromagnetic valve return spring, so that a fuel gas channel is in a closed state), high-pressure fuel gas flows into the pressure stabilizing chamber, and when the pressure in the pressure stabilizing chamber reaches a certain value, a pressure film in the pressure stabilizing chamber moves upwards, so that a connecting rod is driven to move upwards. The lower end of the connecting rod is sleeved at the left end of the lever plug, when the connecting rod moves upwards, the right end of the lever plug is lifted, and the left end of the lever plug moves downwards due to leverage, so that fuel gas is prevented from entering the pressure stabilizing chamber. When the air pressure in the pressure stabilizing chamber is reduced, the pressure film moves downwards under the action of the pressure film reset spring, so that the air re-enters the pressure stabilizing chamber. After the pressure of the fuel gas is regulated by the pressure stabilizing chamber, the high-pressure gas can be converted into stable low-pressure gas, and at the moment, the low-pressure gas comes out of the pressure stabilizing chamber and passes through the plug valve, so that the fuel gas quantity of the fuel gas entering the mixing chamber can be regulated by the plug valve. After being regulated by the plug valve, the fuel gas flows into the air inlet from the fuel gas pipe. The air inlet of the air pump is connected with the air outlet of the mixed gas, when the air pump works, external air passes through the air inlet and is accelerated into high-speed air at the throat of the air inlet (the air flow speed is improved by the slit opening in the middle of the throat through Bernoulli theorem), and the mixed gas flows out of the gas pipe and enters the gas-air mixing chamber. After the gas flowing at high speed and the gas flowing into the mixing chamber, the gas can collide with the gas mixed slurry in the mixer, so that the gas mixed slurry rotates, and the rotating gas mixed slurry can enable the air and the gas to form a plurality of vortexes in the gas-air mixing chamber, so that the air and the gas are mixed more uniformly. The mixed gas which is uniformly mixed in the gas-air mixing chamber flows into a mixed gas outlet under the action of a vacuum pump, the mixed gas flow is regulated into proper air flow in a mixed gas outlet pipe by a mixed gas fine-tuning valve, then the mixed gas flows into the vacuum pump, and the mixed gas is sent to a combustion chamber by the vacuum pump.
