The invention uses butane fuel as power, and utilizes the air pressure generated by explosion of air-fuel mixture in a sealed space to launch seeds. The energy density of butane gas is larger than that of compressed air, the problem of short endurance of the compressed air can be solved, and seeds can be shot into the ground by high-pressure gas generated by explosion to a depth of dozens of centimeters. The high-pressure gas generated by the explosion of butane fuel in a limited closed space is used for emitting seeds, and the cruising ability of the sowing 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.
The use of butane as a power source can greatly reduce carbon emissions 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 launched, the energy of the compressed air is converted into the kinetic energy of the seeds. And the butane is directly used as fuel to launch the seeds, so that the energy loss in the process can be avoided, the utilization efficiency of the energy is improved, and the carbon emission is greatly reduced.

Under the control of the control system program, when the electromagnetic valve is sucked up by the electromagnetic coil (when the electromagnetic valve is in a power-off state, the upper end of the electromagnetic valve is propped against the inlet of the pressure stabilizing chamber under the action of the electromagnetic valve return spring), 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 the 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 due to the lever action, the left end of the lever plug moves downwards, 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 membrane moves downwards under the action of the pressure membrane return spring, so that the air enters the pressure stabilizing chamber again. After the pressure of the gas is regulated in the pressure stabilizing chamber, high-pressure gas can be converted into stable low-pressure gas, and at the moment, the low-pressure gas is discharged from the pressure stabilizing chamber and passes through the plug valve and the plug valve, so that the gas quantity of the gas entering the mixing chamber can be regulated. After being regulated by the plug valve, the fuel gas flows into the air inlet from the fuel gas pipe. When the air pump works, external air passes through the air inlet and is accelerated to high-speed gas at a throat of the air inlet (the flow rate of the gas is increased by using the Bernoulli theorem through a slit in the middle of the throat), and the gas mixed with the gas flowing out of the gas pipe flows into the gas-air mixing chamber. After the gas and the air that flow at a high speed flow into the mixing chamber, can strike the gas mixing thick liquid in the blender for the gas mixing thick liquid is rotatory, and rotatory gas mixing thick liquid can let air and gas form a plurality of vortexes in gas-air mixing chamber, thereby makes air and gas mix more evenly. The mixed gas uniformly mixed in the gas-air mixing chamber flows into a mixed gas outlet under the action of a vacuum pump, is adjusted into gas flow with proper size by a mixed gas fine adjustment valve in a mixed gas outlet pipe, then flows into a vacuum pump, and is delivered to a position needing to be combusted by the vacuum pump.
