DETAILED DESCRIPTION

[0022] The principles and features of the utility model will be described below in combination with embodiments; the examples are only used to explain the utility model; and are not used to limit the scope of the utility model.

[0023] A sulfuryl fluoride metering device for granary fumigation, comprising a metering cylinder 1, a piston 4, a gas outlet pipe 5 and a driving assembly 6.

[0024] The metering cylinder 1 is divided into an upper chamber 7 and a lower chamber 8, and the lower chamber 8 is arranged below the upper chamber 7. Four metering chambers 2 are arranged in a rectangular array in the lower chamber 8, and a distribution chamber 3 is arranged at the bottom of each metering chamber 2. A one-way valve 13 is connected between the distribution chamber 3 and each metering chamber 2, so as to realize one-way conduction from the distribution chamber 3 to the metering chamber 2. The bottom of the metering cylinder 1 is communicated with a source of sulfuric fluoride through a pipe, that is, the sulfuric fluoride enters the distribution chamber 3 of the metering cylinder 1 through the pipe.

[0025] The piston 4 is slidingly connected to the metering chamber 2, and a gas outlet pipe 5 is connected to the bottom of the metering chamber 2. The gas outlet pipe 5 corresponds to each metering chamber 2 and is in communication with each metering chamber 2. The free end of the gas outlet pipe 5 extends out of the metering cylinder 1 and is transmitted to the corresponding granary through a pipe. A one-way valve 13 is connected between the metering chamber 2 and the gas outlet pipe 5, so as to realize one-way conduction from the metering chamber 2 to the gas outlet pipe 5. The upward sliding of the piston 4 can suck the sulfuric fluoride in the distribution chamber 3 into the metering chamber 2, and the downward sliding of the piston 4 can push the sulfuric fluoride in the distribution chamber 3 into the gas outlet pipe 5.

[0026] The driving assembly 6 is used to drive the piston 4 to slide up and down in the metering chamber 2. Specifically, the driving assembly 6 includes a telescopic rod 9, a driving disc 10 and a driving rod 11. The telescopic rod 9 is one of a pneumatic cylinder, a hydraulic cylinder or an electric telescopic rod, and is connected to the metering cylinder 1. The driving disc 10 is connected to the movable end of the telescopic rod 9. One end of the driving rod 11 is fixedly connected to the piston 4, and the other end of the driving rod 11 penetrates through the driving disc 10. An electromagnetic pin 12 is connected in the driving disc 10. The electromagnetic pin 12 corresponds to the driving rod 11. The electromagnetic pin 12 can be popped out to pass through the hole in the top of the driving rod 11 to relatively fix the driving rod 11 to the driving disc 10. The electromagnetic pin 12 can be retracted to separate the driving rod 11 from the driving disc 10.

[0027] A cooling chamber 14 is arranged at the center of the array of the metering chambers 2, and two pipe fittings 15 extending out of the metering cylinder 1 are respectively connected to the two ends of the cooling chamber 14. The cooling chamber 14 can be filled with a cooling medium (such as water) through the pipe fittings 15 to meet the temperature requirement of the sulfuric fluoride.

[0028] In the device, each metering chamber 2 corresponds to a granary. When the granary needs to be fumigated, the corresponding electromagnetic pin 12 is opened to fix the corresponding driving rod 11 to the driving disc 10. The upward sliding of the driving disc 10 can pull up the piston 4 in the corresponding metering chamber 2, and the sulfuric fluoride in the distribution chamber 3 enters the metering chamber 2. The remaining driving rods 11 remain in the original position because they are not relatively fixed to the driving disc 10. When the piston 4 slides downward, the sulfuric fluoride is pushed into the corresponding granary. The sliding distance of the piston 4 is controlled to control the sulfuric fluoride pushed into the granary.

[0029] The above merely describes preferred embodiments of the present application; is not used to limit the present application; any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application; should be included in the protection scope of the present application.
