The installation device includes an installation frame, a storage cylinder, and a first electric push rod. A pull rod is welded to the top surface of the top of the installation frame, and a connecting cylinder is welded to the bottom surface of the top of the installation frame. The storage cylinder is fitted around the pull rod and welded thereon. The storage cylinder is connected to the connecting cylinder via a connecting pipe. The first electric push rod is fixed to the bottom surface of the top of the installation frame by bolts. The discharge mechanism includes a first installation ring, a second installation ring, and a motor. The first installation ring is connected to the bottom surface of the top of the installation frame via the first electric push rod, and the first installation ring is connected to the connecting cylinder via a guide pipe. The motor is located in the inner cavity of the second installation ring and is connected to the inner sidewall of the first installation ring via a second fixing rod. A threaded rod is keyed to the drive end of the motor. The threaded rod passes through the top of the second installation ring and connects to the bottom surface of the top of the first installation ring. The first installation ring and the second installation ring are joined to form a ring structure.

[0006] In a preferred embodiment of this utility model, a second electric push rod is installed on the outer wall of the pull rod via a crossbar. The second electric push rod is located in the inner cavity of the storage cylinder. The moving end of the second electric push rod is fixed with a first slider by bolts. The bottom of the first slider is fixed with a second slider by a first fixing rod. The first slider and the second slider can slide inside the connecting pipe. This is to facilitate the quantitative measurement of fertilizer.

[0007] In a preferred embodiment of this utility model, a vertical rod is mounted on the inner wall of the first mounting ring via a second connecting rod, and a first connecting rod is welded to the inner wall of the second mounting ring. The first connecting rod is connected to the vertical rod via a slider. This is to control the stability of the movement of the second mounting ring.

[0008] In a preferred embodiment of this utility model, a third electric push rod is fixed to the inner sidewall of the first mounting ring by bolts, and a locking rod is fixed to the moving end of the third electric push rod by bolts. The locking rod is located at the midpoint between the bottom surface of the top of the first mounting ring and the top of the second mounting ring; this is to ensure that the two mounting rings can be precisely aligned.

[0020] Example 1: A crop fertilization device includes an installation device 100 and a discharge mechanism 200. The installation device 100 includes an installation frame 110, a storage cylinder 120, and a first electric push rod 130. A pull rod 111 is welded to the top surface of the top of the installation frame 110, and a connecting cylinder 112 is welded to the bottom surface of the top of the installation frame 110. The storage cylinder 120 is fitted over the pull rod 111 and welded to it. The storage cylinder 120 is connected to the connecting cylinder 112 through a connecting pipe 121, which passes through the installation frame 110. The interior of the storage cylinder 120 is welded together with the connecting pipe 121. The two ends of the connecting pipe 121 extend into the inner cavity of the storage cylinder 120 and the inner cavity of the connecting cylinder 112, respectively. The first electric push rod 130 is fixed to the bottom surface of the top of the mounting frame 110 by bolts. The mounting frame 110 is used to provide mounting points for the installation of multiple parts. The interior of the storage cylinder 120 is used to store fertilizer granules. The connecting pipe 121 and the connecting cylinder 112 are used to quantitatively transport the fertilizer in the storage cylinder 120 into the chamber composed of the first mounting ring 210 and the second mounting ring 220.

[0021] Example 2: The discharge mechanism 200 includes a first mounting ring 210, a second mounting ring 220, and a motor 230. The first mounting ring 210 is connected to the bottom surface of the top of the mounting frame 110 via a first electric push rod 130. Both ends of the first electric push rod 130 are fixed to the bottom surface of the top of the mounting frame 110 and the top of the first mounting ring 210 respectively via bolts. The first mounting ring 210 is also connected to the connecting cylinder 112 via a guide tube 113. Both ends of the guide tube 113 are inserted into the bottom of the connecting cylinder 112 and the top of the first mounting ring 210 respectively. The motor 230 is located inside the second mounting ring 220 and is connected to the inner wall of the first mounting ring 210 via a second fixing rod 232. The second fixing rod 232 is welded to the inner wall of the first mounting ring 210. The motor 230 is connected to the second mounting ring 220 via bolts. Fixed to the top of the second fixing rod 232, the drive end of the motor 230 is keyed with a threaded rod 231. The threaded rod 231 passes through the top of the second mounting ring 220 and connects to the bottom surface of the top of the first mounting ring 210. The top of the threaded rod 231 is rotatably connected to the first mounting ring 210 through a bearing. The threaded rod 231 is threadedly connected to the first mounting ring 210. The first mounting ring 210 and the second mounting ring 220 are mated to form a ring structure. The bottom ends of the first mounting ring 210 and the second mounting ring 220 form a conical structure and leave a pit on the soil surface. The cooperation of the motor 230 and the threaded rod 231 can control the second mounting ring 220 to move upward along the outer wall of the first mounting ring 210, causing it to be misaligned, so that a gap is left at the bottom to allow fertilizer to flow out.

[0022] Example 3: A second electric push rod 140 is installed on the outer wall of the pull rod 111 via a crossbar 141. The crossbar 141 is welded to the outer wall of the pull rod 111. The second electric push rod 140 is fixedly connected to the bottom of the crossbar 141 by bolts. The second electric push rod 140 is located in the inner cavity of the storage cylinder 120. The moving end of the second electric push rod 140 is fixed to a first slider 143 by bolts. The bottom of the first slider 143 is fixed to a second slider 144 via a first fixing rod 142. The two ends of the first fixing rod 142 are respectively fixed with bolts. The first slider 143 and the second slider 144 are connected to each other and can slide inside the connecting tube 121. The second electric push rod 140 is used to control the movement of the first fixed rod 142 inside the connecting tube 121. When the first slider 143 moves out of the connecting tube 121, the second slider 144 is located in the inner cavity of the connecting tube 121. At this time, the fertilizer in the storage cylinder 120 flows into the connecting tube 121 through the gap between the first slider 143 and the connecting tube 121 to complete the quantitative measurement of fertilizer. A vertical rod 240 is mounted on the inner wall of the first mounting ring 210 via a second connecting rod 241. The two ends of the second connecting rod 241 are welded to the inner wall of the first mounting ring 210 and the outer wall of the vertical rod 240, respectively. A guide groove is formed on the outer wall of the vertical rod 240. A first connecting rod 222 is welded to the inner wall of the second mounting ring 220. The first connecting rod 222 is connected to the vertical rod 240 via a slider 242. The slider 242 slides in the guide groove. The two ends of the first connecting rod 222 are welded to the slider 242 and the inner wall of the second mounting ring 220, respectively. The cooperation of the vertical rod 240, the slider 242, and the first connecting rod 222 enables the second mounting ring 220 to always be in close contact with the outer wall of the first mounting ring 210 and slide. A third electric push rod 211 is bolted to the inner wall of the first mounting ring 210. A locking rod 212 is bolted to the moving end of the third electric push rod 211. The locking rod 212 is located between the bottom surface of the top of the first mounting ring 210 and the top of the second mounting ring 220. The top of the locking rod 212 contacts and slides against the bottom surface of the top of the first mounting ring 210. The third electric push rod 211 controls the movement of the locking rod 212, preventing the second mounting ring 220 from moving when pressing against the soil surface. A guide rod 221 passes through the top of the first mounting ring 210, and the end of the guide rod 221 is bolted to the top of the second mounting ring 220. The movement of the guide rod 221 restricts the movement trajectory of the second mounting ring 220.

[0023] Working principle: The fertilizer is poured into the inner cavity of the storage cylinder 120. Holding the top of the pull rod 111 firmly, the operator moves it to the base of the crop to be fertilized. At this point, the bottom of the mounting frame 110 contacts the ground. The hand applies downward pressure to the pull rod 111, connecting the first electric push rod 130, the second electric push rod 140, the third electric push rod 211, and the motor 230 to external control equipment and power supply. The second electric push rod 140 pushes the first slider 143 downward, causing it to enter the inner cavity of the connecting pipe 121. At this time, the second slider 144 moves out of the inner cavity of the connecting pipe 121. The measured fertilizer then flows out through the gap between the second slider 144 and the connecting pipe 121, and flows through the guide pipe 113 into the first mounting ring 210 and the second mounting ring 220. Inside the chamber, the control switch of the first electric push rod 130 is operated. The first electric push rod 130 pushes the first mounting ring 210 and the second mounting ring 220 downward as a whole, leaving a pit at their bottom end on the soil surface. Then, the first electric push rod 130 moves upward, causing the first mounting ring 210 and the second mounting ring 220 to separate from the pit. Then, the third electric push rod 211 pulls the locking rod 212 to move, causing the locking rod 212 to separate from the second mounting ring 220. Meanwhile, the motor 230 drives the threaded rod 231 to rotate, causing the second mounting ring 220 to move upward along the outer wall of the first mounting ring 210. This causes the bottom ends of the first mounting ring 210 and the second mounting ring 220 to misalign and open a gap, allowing fertilizer to fall into the pit. Then, the heel presses the soil around the pit, completing the filling of the pit.
