The working principle of the embodiment is as follows:

Firstly, the two hands are manually held to grip the grip 1, downward pressure is applied to the grip 1, so that the second connecting block 206 and the lower end of the second hollow rod 5 are inserted into soil, at the moment, the lower side surface of the cylinder 3 is just attached to the ground, namely, the device is fixed on the ground in a vertical state in an auxiliary manner through the second hollow rod 5, then the positions of the two hands are manually adjusted appropriately, the vertical downward pressure is applied to the grip 1, the cylinder 3 is pressed into the soil, at the moment, a soil column is formed in the cylinder 3, in the process, because the cylinder 3 has a certain thickness, namely, the soil column is formed inside the cylinder 3 in a pressed manner, so that the soil column is pressed on the inner wall of the cylinder 3, and the lower end of the soil column is still connected with the ground, Then the handle 1 is manually rotated back and forth for a small extent, the handle 1 drives the hollow rod I2 and the cylinder 3 to rotate back and forth for a small extent, the cylinder 3 drives the soil column to move through friction force, the connection position between the lower end of the soil column and the ground is torn off, the lower side surface of the soil column is flush with the lower end of the cylinder 3, at the moment, the soil column is fixed on the inner side of the cylinder 3 through friction force, a soil hole is formed at the position of the ground corresponding to the soil column, then the handle 1 is manually driven to move upwards for a certain distance, the handle 1 drives the hollow rod I2 and the cylinder 3 to move upwards, the cylinder 3 drives the soil column to move upwards through friction force, so that a small space is formed between the soil column and the bottom of the soil hole, at the moment, the connecting block II 206 is positioned in the small space, Then the round bar two 205 is manually pushed to move downwards, the round bar two 205 drives the connecting block two 206 to move downwards, the connecting block two 206 stops blocking the lower end of the hollow bar two 5, then the fertilizer dispenser 4 conveys a proper amount of fertilizer to the housing 7, the fertilizer flows into the inner side of the hollow bar two 5 sequentially through the cavity 91 and the round hole 92, then flows out of the lower end of the hollow bar two 5 to the bottom of the inner side of the soil hole to form a first fertilizer layer, then the motor two 208 is started, the motor two 208 drives the gear two 209 to rotate, the gear two 209 drives the gear three 2010 to rotate, the gear three 2010 drives the hollow bar two 5 to rotate, the hollow bar two 5 drives the round bar one 6 to rotate, Cutting off the lower end of the soil column by the round bar I6 to obtain a first soil cake, then closing the motor II 208, starting the motor I2011, enabling the motor I2011 to drive the gear I2012 to rotate, enabling the gear I2012 to drive the rack 2013 to move downwards, enabling the rack 2013 to drive the slide bar 203 to move downwards, enabling the slide bar 203 to drive the push block I201 to move downwards, enabling the push block I201 to drive the push block II 202 to move downwards, enabling the push block II 202 to slide downwards on the surface of the hollow bar II 5, enabling the push block I201 and the push block II 202 to simultaneously push the soil column to move downwards, enabling the soil column to push the first soil cake to move downwards, enabling the first soil cake to be separated from the cylinder 3, Then, manually driving the handle 1 to move upwards, driving the hollow rod I2 and parts thereon to move upwards, enabling the lower end of the hollow rod II 5 to move to the position above the first soil cake, repeating the operation, filling the second soil cake on the first soil cake, repeating the operation, cutting off the lower part of the soil column again to obtain a second soil cake, transferring the second soil cake to the position above the second soil cake, and reciprocating in this way, filling fertilizer and soil into soil holes in a crossing manner, ensuring that the uppermost part in the soil hole is the soil layer, and completing fertilization operation;

After the fertilizer flows vertically downwards into the soil hole from the lower port of the hollow rod II 5, the vertically falling fertilizer is accumulated in the middle of the soil hole due to the fact that the lower port of the hollow rod II 5 is positioned in the middle of the soil hole, and the distribution is uneven, so that the fertilizer flows out from the lower port of the hollow rod II 5 and contacts with the conical surface on the upper side of the connecting block III 207, and is guided outwards obliquely through the conical surface, so that the fertilizer is relatively evenly filled into the soil hole;

after fertilization is completed, part of relatively fine fertilizer dust particles float on the inner side of the hollow rod II 5 and then flow out of the lower end of the hollow rod II 5 to pollute the environment, so that after fertilization is completed, the round rod II 205 is manually pulled to move upwards, the round rod II 205 drives the connecting block III 207 to move upwards, the lower end of the hollow rod II 5 is blocked, and fertilizer dust in the hollow rod II is prevented from scattering into the external environment;

during the cutting of the soil column by the round bar one 6 described in example 1:

Because the hollow rod II 5 passes through the middle part of the soil column to form a through hole in the middle part of the soil column, after the soil column is cut into soil cakes, a through hole is formed in the middle part of the soil cakes, when fertilizer is filled, part of the fertilizer can be accumulated in the through hole to influence the dispersion degree of the fertilizer, therefore, when the hollow rod II 5 drives the round rod I6 to rotate to cut the soil column, the round rod I6 drives the round rod III 2015 to perform circular motion, the round rod III 2015 spreads the soil cakes to prepare loose soil, the loose soil falls above a fertilizer layer, the fertilizer layer is buried, and then the next fertilizer layer is filled above the loose soil layer, so that the problem of fertilizer accumulation caused by the through hole on the soil cake is avoided;

When the hollow rod two 5 drives the round rod one 6 to rotate, the round rod one 6 drives the round ring one 2016 to rotate, the round rod one 6 contacts the linkage block 2019 in the moving process, the linkage block 2019 blocks and limits the round rod one 6, the end of the round rod one 6 moves along the inclined plane of the linkage block 2019 and compresses the spring 2018, when the round rod one 6 passes through the linkage block 2019, the spring 2018 rebounds to drive the round ring two 2017 and the round rod one 6 to move back to the original position, namely, the round rod one 6 moves in a circular motion and simultaneously moves in a linear reciprocating motion, the round rod one 6 drives the round rod three 2015 to move, and the round rod three 2015 moves in a circular motion and simultaneously moves in a linear reciprocating motion, so that the scattering effect of the round rod three 2015 on a soil cake is improved.

During the flow of fertilizer through the hollow bar two 5 as described in example 2:

after the soil cake is scattered by the round rod I6 and the round rod III 2015, the scattered soil falls off the cylinder 3, at the moment, the soil column in the cylinder 3 is higher than the round rod I6, then, the fertilizer dispenser 4 starts to convey fertilizer, the fertilizer flows to the inner side of the elastic cylinder 2021 from the upper part of the hollow rod II 5 and flows out from the lower end of the hollow rod II 5, in the process, the hollow rod II 5 continuously drives the round rod I6 to rotate, the round rod I6 drives the connecting block IV 2020 to perform linear reciprocating motion, the connecting block IV 2020 intermittently knocks the elastic cylinder 2021, and the elastic cylinder 2021 rapidly shakes the fertilizer in the elastic cylinder to avoid blocking.

According to the working principle, the invention has the following effects:

The round rod one 6 is also used for driving the connecting block four 2020 to intermittently strike the elastic cylinder 2021, so that the elastic cylinder 2021 can quickly shake off the fertilizer in the elastic cylinder, and the blocking phenomenon is avoided.
