in the first embodiment, the invention simplifies the structure of the moving frame 1, combines the hands and the feet of a grower to operate the moving frame, wherein the hand holds the handle position of the moving frame 12 on the moving frame 1, moves the moving frame 1 to a position to be punched, aligns the drill bit 3 at the punching position, steps one foot on the stepping part of the motor support 11, starts the motor switch button on the control box 13 after preparation, starts the motor 2 to drive the drill bit 3 to work, switches the control button of the air pump 14 on the control box 13 to slow down the inflation rate of the inflatable cushion 4, opens the air release valve 18 for air release, at the moment, the drill bit 3 starts to dig a hole, the drill bit 3 deflects and moves downwards along with the motor support 11 relative to the moving frame 12 to increase the digging depth along with the reduction of the air amount in the inflatable cushion 4, and the manpower applied by the stepping part is used for ensuring the stability and simultaneously manually controlling the digging depth, and the emergency caused by unclear soil condition can be stopped in time, and the time from the manual control of the control button of the air pump 14 on the switching control box 13 to the increase of the reaction time of the inflation rate of the inflatable cushion 4 can be provided, so that the operation controllability can be increased;

then, after the pit is dug to a certain degree, the fertilizer in the hopper 4 can be discharged into the dug pit through the discharge pipe 15, at this time, the hopper 4 can be controlled by the controller to automatically discharge the fertilizer in the process of digging the pit, or the fertilizer can be automatically applied after the end of digging the pit, and the specific operation can be seen in the second embodiment;

in the second embodiment, the invention explains the concrete process of digging a pit and briefly explains various automatic fertilizing modes; in the embodiment, attention is paid to and emphasis is placed on a specific mode of automatic fertilization, wherein in the first mode, the air release valve 18 is opened at the beginning stage of pit digging to release air from the inflatable cushion 6, the released air is discharged into the hopper 4 to form a pressurized environment, at the moment, the pressure value in the box is detected through the pressure sensing device 17 and fed back to the controller 13, whether the pressure value reaches the preset induction trigger value is compared in the controller 13, if the preset pressure value is reached, the discharge signal is transmitted to the discharge valve 16 in real time, the discharge valve 16 is opened to realize discharge, in the process, the motor support 11 and the movable support 12 rotate relatively due to gradual air release of the inflatable cushion 6, the action that the drill bit gradually and stably moves down to dig the pit in the first embodiment is realized, and fertilizer is brought into soil along with the rotation of the drill bit during pit digging, the state of this moment is similar to and stirs the mixture with fertilizer and the earth that drills out in step, the in-process that relies on the extrusion force when the drill bit gets into the soil carries solid or liquid fertilizer into the hack that drills out promptly, and utilize the rotation of drill bit to make fertilizer and hack that drills out fully mix at the in-process of boring continuously, avoid filling fertilizer after boring to lead to the excessive, the too concentrated plant root system that appears absorbs inadequately or the problem of burning seedlings, make fertilizer disperse evenly in the hack that drills out, no matter be used for backfilling or the infiltration of watering after the external cover, can guarantee the scattered root system of plant and to the even degree that fertilizer absorbs, guaranteed the even degree that follow-up plant root system grows, the fertilizer of this kind of mode is applied, then more be used for the plant that needs synchronous growth to main, vice root system, for example short plants such as the bush-wood branch of the department.

In a second mode, when the air pump 14 is used for inflating the inflatable cushion 6 in the drill bit rising stage after the pit digging is finished, the release valve 18 is opened to discharge part of the gas in the charged gas cushion 6 into the hopper 4 to form a pressurized environment, and at this time, the same operations of pressure detection and signal transmission in the first mode are used for discharging, but the discharging is accompanied with the ascending process of the drill bit, in the process, the fertilizer is discharged with certain acceleration given by pressure, and the drill bit carries the crushed soil and presents a state of spraying the crushed soil to the periphery in the range from the bottom of the pit to the position just separated from the opening of the pit, therefore, part of the fertilizer is brought out by the outward throwing force of the crushed soil at the stage and is scattered in the peripheral crushed soil pile, the fertilizer is uniformly distributed on the surface of the crushed soil pile and is covered by the crushed soil finally taken out by the drill bit; a part of fertilizer directly falls into the pit along the spiral track of the drill after the drill is separated from the pithead, and the fertilizer is stopped to be output until the drill returns; the fertilizer is applied in such a way, so that the fertilizer is more suitable for plants which need to grow preferentially aiming at the main root system and grow gradually by the auxiliary root system, such as tall plants in arbor families and the like.

It can be found that different application effects are brought by different execution sequences of fertilizer output in the first mode or the second mode, different plant application requirements are met, and the process is accompanied with downward moving and lifting operations of the pit drilling device, so that the fertilizer application amount can be controlled and manual operation is facilitated.

Third embodiment, in order to make the motor 2 and the hopper 4 in the first and second embodiments always keep moving up and down in the vertical direction along with the increase of the depth of the drilled pit, the invention adds a shaft and a coil spring at the connecting part of the motor 2 and the hopper 4 with the motor bracket respectively, and sets a telescopic cylinder 7 with a downward output end at one side of the motor 2, when the depth of the drilled pit gradually increases, the controller 13 receives the feedback of air leakage of the inflatable cushion 6 and then starts the control of supplying air to the telescopic cylinder 7 by the air pump 14, and extends out and abuts against the ground outside the position of the drilled pit, and because the telescopic cylinder 7 is connected with the motor 2, under the condition that the telescopic cylinder 7 is vertical to the ground, the motor 2 will also keep horizontal to the ground, namely, deflect relative to the motor bracket 11 under the action of the coil spring and the shaft, along with the increase of the depth of the drilled hole, the controller can be manually controlled to change the air supply amount to the telescopic cylinder 7, the extending distance is controlled, and the height of the position where the drill bit is located is changed, so that the purpose of changing the hole digging depth is achieved;

in addition, because the elastic part 5 is arranged between the motor 7 and the hopper 4, firstly, the vibration generated by the operation of the motor 7 is used for preventing the materials on the inner surface of the hopper 4 from being adhered, and the smooth blanking is kept; but when the motor deflects relative to the motor support 11, the hopper can also deflect under the action of the shaft and the coil spring, so that the discharge pipe is close to the pithead, thereby avoiding that excessive fertilizer is scattered outside the pit and the uniform distribution effect can not be realized.

It should be noted that the air release feedback of the inflatable cushion 6 is determined according to the pressure change captured by the pressure sensing device 17 in the guide hopper 4 when the air release valve 18 is opened to guide the air of the inflatable cushion 6 into the hopper 4;

finally, the motor bracket 11 and the movable bracket 12 are hinged at one point of the motor bracket 11 and the movable bracket 12 to be mounted in a scissor structure state, and the motor bracket 11 and the movable bracket 12 both adopt a deformed Z-shaped structure to realize structural stability after mounting;

wherein the control box 13 and the air pump 14 are arranged at the opposite upper ends of the movable bracket 12, and the part is simultaneously positioned at the position of a handle 15 for pushing the movable frame 1 to walk, and is used for enabling the control box 13 and the air pump 14 to be used as weight pieces and a motor arranged on the motor bracket 11 to be in a stable weight distribution structure.
