The working principle is as follows: when the device works, a worker inserts the device between fields to be subjected to slow release of liquid fertilizer, rotates the bracket 900 to enable the opening of the bracket 900 to face outwards, then erects the device on the ground, and inserts the pin 402 into the inside of the ground by means of treading the pedal to apply force.

In operation, pin 402 is embedded in ground and is matched with bottom frame 401 to support the device, synchronously, when bottom frame 401 moves downwards, lower plate 803 is squeezed by ground relative movement, it drives upper plate 801 to move upwards relative to bottom frame 401 through connecting rod 802, and drives rack plate 505 to move upwards relative to bottom frame 401, at this moment, with the help of tooth meshing transmission between rack plate 505 and outer toothed ring 504, so that sleeve 503 rotates, medicine spraying mechanism 600 is put down, so that medicine spraying mechanism 600 is flush with ground as a whole, and bracket 900 is supported on ground.

In operation, a worker pulls outer tube 602 outward to move outer tube 602 outward relative to inner tube 601, and when outer tube 602 is adjusted to a proper position, the worker rotates bolt 604 to move bolt 604 inside nut 603 by means of the engagement of threads, so that bolt 604 presses on the outer surface of inner tube 601 to fix the position of outer tube 602.

When the device works, a worker drives the worm 305 to rotate through rotating the grip, and the shell 303 is rotated by means of tooth meshing between the worm 305 and the worm wheel 304, so that the inclination angle of the valve port in the shell 303 is adjusted, and the overall liquid fertilizer circulation speed of the device is controlled.

During operation, when external environment is in high temperature weather, receive high temperature weather's influence for the inside temperature of metal gas pitcher 701 risees, and under the effect of high temperature inflation, the inside gas of metal gas pitcher 701 is heated the inflation, pushes up the valve plate 704 of the inside embedding of stack shell 702, under the linkage of push rod 703, makes backstop 202 pushed, and the inside through-hole dislocation of backstop 202 at this moment squints, then switches on and ends, and the device can't carry out releasing of liquid fertilizer under this state.

When the device works, when the outside is in the daytime, the reflecting patch 706 can effectively collect sunlight, and the response sensitivity of the device is improved.

The during operation, when external environment is in low temperature weather, influenced by temperature change, the inside temperature of metal gas pitcher 701 reduces, its inside gas volume shrink loses the promotion to the inside valve plate 704 of embedding of stack shell 702, make backstop 202 lose gaseous external force to support, under the elastic deformation reset action of spring 203, make backstop 202 reset, the inside through-hole of backstop 202 switches on upper and lower hookup location department at casing 201 again, make the device carry out liquid fertilizer under low temperature environment and discharge the operation, carry out the slowly-releasing operation to liquid fertilizer.

When the device works, after fertilization is finished, a worker shrinks the outer pipe 602 and the inner pipe 601 through adjustment, the bracket 900 is turned over to face the liquid storage tank 100 through rotation, then the worker pulls out the device upwards, the upper plate 801 moves downwards relative to the bottom frame 401 under the elastic support of the second spring 804, the rack plate 505 is driven to move downwards relative to the bottom frame 401, and the pesticide spraying mechanism 600 automatically turns over and vertically retracts.
