Nowadays, with the emergence of a series of economic crops that have high requirements on soil, such as off-season vegetables and flower greenhouses, soil disinfection is becoming more and more important. In the past, soil disinfection methods were mainly chemical disinfection methods. However, the contamination of soil by chemical agents is increasing, and the resistance of bacteria is becoming stronger and stronger. Therefore, compared with chemical soil disinfection, other disinfection methods (solar disinfection, high-pressure disinfection, steam disinfection, hot air disinfection, etc.) Welcome, and easy to realize automatic operation, saving human resources, more efficient and convenient than other methods.

The disinfection method of hot air soil disinfection is physical disinfection, which is clean and environmentally friendly, and there is no pollution and residue of chemical disinfection on the land. Hot air soil disinfection is a fast and efficient soil disinfection method. Its disinfection method is: heating the air to a certain temperature, using high temperature and dry heat to oxidize microorganisms and denature proteins, thereby killing pests, germs, viruses and even weed seeds in the soil together. Hot air soil disinfection effectively solves the disadvantages of the above-mentioned chemical agent disinfection on the land.

detailed description

As shown in Figures 1-2, in the fully hydraulic self-propelled soil circulation disinfection machine provided by the utility model, the diesel engine 1 is the power source of the whole machine, which drives the diesel generator 15 to work through the belt, and drives the hydraulic pressure through the crank linkage mechanism. The oil pump 16 works. Diesel generator 15 is the power supply of the whole machine. It supplies power to blower 2 , UV lamp 12 and microwave generator 9 . There is a heating wire inside the blower 2, and the heating wire can heat the air after being energized. The air outlet duct 13 is connected with the hot air spray nozzle 4 through a pipeline. The hot blast is blown out by the blower 2 with the heating wire inside, and is sprayed by the hot blast nozzle 4 through the air outlet duct 13 for disinfection. The air inlet pipe 5 is connected with the air inlet of the air blower 2, sucks the air with lower temperature into the air blower 2, and is reheated by the heating wire to form an internal circulation. This can make full use of heat. Filter screen is arranged in the air inlet pipe 5, and air can be filtered, prevents that soil particle enters blower, to cause damage. Moreover, this sterilizer has a temperature sensor and its auxiliary control device (not shown) to realize automatic temperature control. In order to achieve a better anti-virus effect, the temperature should be controlled at 300°C-500°C. The ultraviolet lamp 12 and the microwave generator 9 can improve the disinfection efficiency, and both the ultraviolet lamp 12 and the microwave generator 9 are arranged on the side wall of the casing 3 to have a better disinfection effect. The hydraulic oil pump 16 drives the complete machine hydraulic system. Regulating the hydraulic valve 14 can control the entire hydraulic system. The hydraulic motor 10 is connected to the hydraulic oil pump 16 through the oil pipe to drive the rotary cultivator 8 to rotate, realize the function of plowing the soil, and carry out better disinfection. The hydraulic cylinder 11 is also connected to the hydraulic oil pump 16 to realize the lifting of the rotary tillage mechanism, so as to facilitate walking, carrying and adjusting the depth of rotary tillage.

The blower 2 can also be directly connected to an external power supply or a storage battery, and an electric heating plate can also be arranged inside the blower 2 or an electric furnace can be set at the outlet of the blower 2 .

The blowing duct includes an air inlet duct and an air outlet duct connected with the blowing device, and the outlet duct is connected with a checkerboard hot air duct.

The checkerboard hot air duct includes peripheral ducts and middle ducts, the peripheral ducts are arranged around the middle ducts, the peripheral ducts are connected to the middle ducts, the middle ducts are intersected, the junctions of the peripheral ducts and the middle ducts and the cross connections between the middle ducts An air outlet and/or an air outlet is arranged on the peripheral pipe and the middle pipe, and a hot air nozzle 4 is arranged at the air outlet. The intersection angle between the intermediate pipes is 30°, 45°, 60°, 90° or 120°.

The hydraulic oil pump drives the work of the hydraulic system of the whole machine. Whole hydraulic system is made up of hydraulic oil pump 16, single-column piston cylinder, hydraulic motor, oil pipe, fuel tank and some other hydraulic auxiliary components. The sterilizer has a rotary tillage working device and a driving working device. Powered by the diesel engine 1, through the action of the hydraulic oil pump 16, it drives the single-column piston cylinder to realize the lifting of the rotary tillage mechanism and drives the hydraulic motor 10 of the rotary tillage part to work. There is no need for steering and speed regulation, only the rotary tiller Machine 8 rotates by fixed speed and gets final product. The part of the driving hydraulic system is designed as a crawler belt 6 transmission. In order to make the machine move forward and turn flexibly, a hydraulic motor 10 needs to be provided on the left and right sides. At the same time, steering gear, diverter valve, hydraulic pump and other hydraulic auxiliary components are also required. The steering gear has a receiving device, and the signal is sent by the remote control device. When the receiver receives the forward signal, the hydraulic oil pump 16 will provide the same oil intake to the two hydraulic motors 10. After the two motors have the same speed, they will It will drive the crawler belt 6 to move forward; if you want the machine to turn left and right, the remote control device will send different signals, and the receiving device will change the amount of oil supplied to the two hydraulic motors 10 according to the received signals, and then the motors will The rotating speed of crawler belt 6 just can change, and the rotating speed of crawler belt 6 is different, and machine can turn to the side that rotating speed is little naturally. The steering angle can be controlled by the remote control device, realizing the free travel of the machine from 0 to 360°.

In order to facilitate working on relatively soft ground, and at the same time increase the carrying capacity of the machine to meet the requirements of normal work. Make sure that the traveling device of this machine is composed of the identical two-part structure of the crawler-type traveling device. In order to achieve better land cultivation effects, realize optimal disinfection, and reduce disinfection costs, this machine has selected a horizontal-axis rotary tillage mechanism. The working parts of the rotary tiller mechanism include a rotary tiller shaft, a number of soil cutting blades arranged according to certain rules, and a transmission device.

The exhaust gas from the combustion device for air heating will cause air pollution, but our soil disinfection is electric heating, so there will be no air pollution. Since our soil sterilizer uses electric heating, the temperature inside the sterilizer can be automatically controlled through temperature sensors and control devices. This will not cause temperature fluctuations. And because the temperature is relatively constant, it will not cause incomplete disinfection or damage to the soil.
