A second baffle is fixed to the bottom of the first baffle via a connecting rod. The bottom of the second baffle contacts the rotating plate via a pressing column. The material distribution cylinder is fixed to the outer wall of the extrusion cylinder by a crossbar. Both ends of the material distribution cylinder are connected to the inner cavity of the extrusion cylinder via a discharge pipe and a feed pipe, respectively.

[0006] In order to adjust the space inside the distributing cylinder and adjust the amount of material discharged, as a preferred embodiment of the crop fertilization device of this utility model, the distributing cylinder includes a sleeve and a rotating cylinder. The rotating cylinder is threadedly connected to the inner wall of the sleeve. The end of the discharge pipe is inserted into the top of the sleeve.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution, which includes an installation structure 100 and a discharge device 200.

[0020] In this technical solution, a crop fertilization device has an installation structure 100 including a pole 110 and a storage cylinder 120. The top and bottom of the pole 110 are respectively welded with a top plate 111 and a bottom plate 115. The storage cylinder 120 is carried on the back by a shoulder strap. The two ends of the shoulder strap are respectively connected to the outer wall of the storage cylinder 120 by bolts. A connecting pipe 121 is inserted into the bottom of the storage cylinder 120.

[0021] In this technical solution, the upright 110 provides an installation point for the installation of multiple parts, the inner cavity of the storage cylinder 120 is used to hold fertilizer granules to be fertilized, and the base plate 115 can increase the force-bearing area between the upright 110 and the ground so that the extrusion cylinder 220 can be stably inserted into the soil.

[0022] The discharge device 200 includes a first electric push rod 210, an extrusion cylinder 220, a distributing cylinder 230, and a second electric push rod 240. The fixed end of the first electric push rod 210 is connected to the outer wall of the upright 110 via a horizontal plate 114, which is welded to the outer wall of the upright 110. The fixed end of the first electric push rod 210 is fixed to the horizontal plate 114 with bolts. The extrusion cylinder 220 is connected to the moving end of the first electric push rod 210 with bolts. The bottom of the inner cavity of the extrusion cylinder 220... A rotating plate 225 is mounted via a rotating shaft. A torsion spring is installed between the rotating plate 225 and the inner wall of the extrusion cylinder 220. The rotating shaft passes through the extrusion cylinder 220 and the rotating plate 225, while the torsion spring is sleeved on the outside of the rotating shaft. The two ends of the torsion spring are respectively inserted into the rotating plate 225 and the extrusion cylinder 220. A second electric push rod 240 is fixed to the top of the inner cavity of the extrusion cylinder 220 by bolts. The moving end of the second electric push rod 240 is fixed to a first baffle 241 by bolts. The bottom of the first baffle 241... A second baffle 243 is fixed to a connecting rod 242. Both ends of the connecting rod 242 are fixed to the first baffle 241 and the second baffle 243 respectively by bolts. The first baffle 241 and the second baffle 243 slide along the inner wall of the extrusion cylinder 220. The bottom of the second baffle 243 contacts the rotating plate 225 via pressing posts 244. Multiple pressing posts 244 are evenly distributed at the bottom of the second baffle 243 and welded together. The distributing cylinder 230 is fixed to the extrusion cylinder 220 by a crossbar. The outer side wall of the extrusion cylinder 220 is welded to the crossbar. The sleeve 231 is fixed to the crossbar by bolts. The two ends of the distribution cylinder 230 are connected to the inner cavity of the extrusion cylinder 220 through the discharge pipe 222 and the feed pipe 223, respectively. The discharge pipe 222 and the feed pipe 223 extend into the inner cavity of the extrusion cylinder 220. When the first baffle 241 and the second baffle 243 move in the inner cavity of the extrusion cylinder 220, they can only completely close the port of the discharge pipe 222 or the feed pipe 223 at a time.

[0023] In this technical solution, the first electric push rod 210 controls the vertical movement of the extrusion cylinder 220, pressing it into a depression on the soil surface; the second electric push rod 240 controls the movement of the first baffle 241, connecting rod 242, and second baffle 243 within the cavity of the extrusion cylinder 220. Fertilizer granules in the storage cylinder 120 can temporarily flow into the chamber formed between the first baffle 241 and the extrusion cylinder 220 through the connecting pipe 121. When it is necessary to fill the dispensing cylinder 230, the second electric push rod 240 pushes the first baffle 241, connecting rod 242, and second baffle 243 downwards, so that the second baffle 243 completely blocks the port of the feed pipe 223 and continues to move downwards, while the pressing column 244 presses the rotating plate 225. This causes the rotating plate 225 to change from an inclined state to a horizontal state, completing the sealing of the bottom opening of the extrusion cylinder 220. At this time, the first baffle 241 is misaligned with the end of the discharge pipe 222, allowing the fertilizer to flow into the inner cavity of the distribution cylinder 230 through the discharge pipe 222, completing the distribution. When discharge is required, the second electric push rod 240 drives the first baffle 241 to move upward, so that the first baffle 241 completely seals the end of the discharge pipe 222 and continues to move upward, causing the second baffle 243 to be misaligned with the feed pipe 223, and the pressing column 244 to separate from the rotating plate 225. The rotating plate 225 rotates under the action of the torsion spring to open the opening at the bottom of the extrusion cylinder 220. At this time, the fertilizer in the distribution cylinder 230 flows out and falls through the feed pipe 223, and enters the pit through the opening.

[0024] In some technical solutions, reference Figure 1 and Figure 4 The distributing cylinder 230 includes a sleeve 231 and a rotating cylinder 232. The rotating cylinder 232 is threadedly connected to the inner wall of the sleeve 231. The end of the discharge pipe 222 is inserted into the top of the sleeve 231. The end of the feed pipe 223 rotates with the bottom of the rotating cylinder 232 through a rotating ring. The rotating ring rotates at the bottom of the rotating cylinder 232. The end of the feed pipe 223 is fixed to the rotating ring by bolts.

[0025] In this technical solution, when it is necessary to adjust the amount of material discharged, the rotating drum 232 is manually rotated so that the rotating drum 232 rotates inside the sleeve 231 to adjust the size of the inner cavity of the distributing drum 230, thereby controlling the amount of material discharged.

[0026] In some technical solutions, reference Figure 1-4 A collar 112 is fitted on the outer side of the top of the upright 110. A spring 113 is fixed between the collar 112 and the top plate 111 by bolts. A pull rope 130 is fixed to the outer wall of the collar 112 by bolts. The end of the pull rope 130 passes through the outer wall of the extrusion cylinder 220 and is fixed to the top of the rotating plate 225. The pull rope 130 passes through the interior of the horizontal plate 114 and the sleeve plate 221 from top to bottom.

[0027] In this technical solution, the collar 112 is pulled manually. At this time, the pull rope 130 provides a pulling force to the end of the rotating plate 225 as the collar 112 moves, which helps to drive the rotation of the rotating plate 225. Meanwhile, the spring 113 is in a compressed state. When the finger is separated from the collar 112, the collar 112 can be reset under the action of the spring 113.

[0028] In some technical solutions, reference Figure 1 , Figure 3 and Figure 4 The extrusion cylinder 220 is fitted with a sleeve plate 221, which is welded to the upright 110.

[0029] In this technical solution, the use of the sleeve plate 221 can control the movement of the extrusion cylinder 220 in the vertical direction, so that the end of the extrusion cylinder 220 can be pressed vertically onto the surface of the soil.

[0030] In some technical solutions, reference Figure 3-4 A stop 224 is fixed to the lower inner wall of the extrusion cylinder 220 by bolts, and the stop 224 can contact the surface of the rotating plate 225 after rotation.

[0031] In this technical solution, after the rotating plate 225 rotates in the inner cavity of the extrusion cylinder 220, the opening at the bottom of the extrusion cylinder 220 is opened. The rotation angle of the rotating plate 225 can be controlled by the stop block 224 to prevent the rotation angle from being too large. After the rotating plate 225 is pressed by the pressing column 244, it cannot be reset.

[0032] Working principle: Holding the upright pole 110 and gripping the top plate 111, pour fertilizer into the inner cavity of the storage cylinder 120 and carry it on your back using the shoulder strap. Connect the first electric push rod 210 and the second electric push rod 240 to the external control equipment and power supply. When fertilizing crops, place the bottom of the upright pole 110 close to the roots of the crops, with the bottom plate 115 in contact with the ground. At this time, operate the control switch of the first electric push rod 210. The first electric push rod 210 drives the extrusion cylinder 220 to move downward, pressing a dent into the ground at the bottom of the extrusion cylinder 220 (at this time, the spring 113 is stretched by the pull rope 130). The first electric push rod 210 drives the extrusion cylinder 220 to move upward a certain distance, but does not move out of the dent. At this time, while operating the control switch of the second electric push rod 240, hook your finger on the collar 112 and pull upward. The second electric push rod 240 drives the first baffle 241, the connecting rod 242 and the second baffle 240 to move upward. Plate 243 moves upward within the inner cavity of the extrusion cylinder 220. At this time, the first baffle 241 gradually blocks the port of the discharge pipe 222, while the pressing column 244 gradually moves away from the rotating plate 225. The rotating plate 225 can then rotate under the drive of the torsion spring and the pull rope 130 to open the opening at the bottom of the extrusion cylinder 220. At this time, the fertilizer located in the inner cavity of the distribution cylinder 230 flows out through the feed pipe 223 and flows from the opening to the pit to complete the fertilization. Then, the top of the pit is pressed with the sole of the foot. Once the soil is sealed, the second electric push rod 240 pushes the first baffle 241 downward in the inner cavity of the extrusion cylinder 220, causing the first baffle 241, the second baffle 243, and the rotating plate 225 to reset, thus resealing the port of the feed pipe 223. This allows the fertilizer in the inner cavity of the storage cylinder 120 to flow into the extrusion cylinder 220 through the connecting pipe 121 and then flow from the discharge pipe 222 to the inner cavity of the distribution cylinder 230, so that the next crop can be fertilized in the same amount.
