[0023] As Figure 1 with Figures 6 to 8As shown, the sharp shovel 301 is fixedly installed at one end of the distribution barrel 201 away from the middle tube 103, the fertilizer hole is arranged in the sharp shovel 301, the axis of the fertilizer hole in the sharp shovel 301 is aligned with the axis of the hole in the middle tube 103, the pedal 302 is slidably installed on the outer wall of the sharp shovel 301, a plurality of return springs are fixedly installed on the pedal 302, the other end of the return spring is fixedly installed on the sharp shovel 301 to make the pedal 302 reciprocate, a sharp cutting edge is arranged at the end of the sharp shovel 301 away from the distribution barrel 201 to make the device penetrate into the soil, the rotating shaft 306 is fixedly installed on the sharp shovel 301, the extrusion arc plate 304 is rotatably installed on the rotating shaft 306, the return torsion spring is arranged between the rotating shaft 306 and the extrusion arc plate 304, the return torsion spring is used to make the extrusion arc plate 304 return to the initial position, and the extrusion arc plate 304 is always in close contact with the sharp shovel 301 without external force, one end of the extrusion arc plate 304 is provided with a pawl to extrude the soil, and the extrusion arc plate 304 can close the fertilizer hole in the sharp shovel 301, and the fertilizer hole is opened only after the extrusion arc plate 304 rotates, and if the sharp shovel 301 is in the soil when the extrusion arc plate 304 rotates, the extrusion arc plate 304 will extrude a certain internal space in the soil.
[0024] As Figure 1 With Figures 6 to 8 As shown, the stretch rod 303 is slidably installed in the sharp shovel 301, one end of the stretch rod 303 is fixedly connected with the pedal 302, the other end of the stretch rod 303 is in movable contact with the extrusion arc plate 304, when the pedal 302 is stepped and the stretch rod 303 moves away from the distribution barrel 201, the stretch rod 303 will press the extrusion arc plate 304 through the rubber pressing block 305 to make the extrusion arc plate 304 rotate around the rotating shaft 306, and after rotating, the extrusion arc plate 304 will open the fertilizer hole on the sharp shovel 301.
[0025] As Figure 1 , Figure 2 With Figures 6 to 8As shown, the displacement rod 209 is fixedly installed on the pedal 302, and the displacement rod 209 is in sliding connection with the sharp shovel 301 and in sliding connection with the distribution cylinder 201. The displacement rod 209 is L-shaped, and the flexible rod 206 is fixedly installed on the displacement rod 209. The flexible rod 206 is made of hard rubber or a metal material with a certain elasticity. The flexible rod 206 is fixedly installed with the extrusion cylinder 204 at one end away from the displacement rod 209. The extrusion cylinder 204 drives the rotating disc 205 to rotate by moving up and down. In this process, when the flexible rod 206 moves downward through the extrusion cylinder 204, the rotating disc 205 is extruded to rotate by the extrusion cylinder 204. The rotating disc 205 rotates with the sliding key shaft 207 and the distribution column 210. Since the stroke of the sharp shovel 301 is limited, the rotating disc 205 will only rotate 60 degrees around the axis of the distribution column 210 each time. When the rotating disc 205 is driven, the flexible rod 206 will also bend to adapt to the arc of the arc slot on the rotating disc 205, so that the extrusion cylinder 204 is tightly fitted with the arc slot on the rotating disc 205.
[0026] When the device is used, fertilizer particles need to be placed in the storage box 102. At this time, the fertilizer particles will be in the hole in the middle tube 103. Before use, the user needs to rotate the distribution column 210 by 120 degrees. This can prepare the device for work.
[0027] When used, the user holds the handle 101 with his hand, and then inserts the sharp shovel 301 into the soil to be fertilized at an angle or vertically. Then the sharp shovel 301 penetrates into the soil. Then the user steps on the pedal 302 to move the pedal 302 away from the distribution cylinder 201. This makes the pedal 302 drive the rotating disc 205 in the distribution cylinder 201 through the displacement rod 209 and the extrusion cylinder 204. The rotating disc 205 rotates 60 degrees with the sliding key shaft 207 and the distribution column 210. After the flexible rod 206 rotates 60 degrees, a distribution groove 211 full of fertilizer will be rotated above the sharp shovel 301. Thus, the fertilizer will fall into the fertilizer hole in the sharp shovel 301. When the pedal 302 is stepped on, the extrusion arc plate 304 on the sharp shovel 301 is driven to rotate, so that the extrusion arc plate 304 opens the fertilizer hole on the sharp shovel 301, and the fertilizer particles enter the soil space extruded by the extrusion arc plate 304. After fertilization is completed, the user can pull out the sharp shovel 301 from the soil. It is worth noting that the pedal 302 can be released only after the action of pulling out the sharp shovel 301 from the soil begins, in order to prevent the extrusion arc plate 304 from bringing the fertilizer back into the sharp shovel 301 when it returns to the initial position. The working process of the user is to step on the pedal 302 after inserting the device into the soil, and then pull out the device from the soil and release the pedal 302.
[0028] When the device needs to adjust the fertilizer dosage, only need to rotate the adjusting bolt 202, let the adjusting bolt 202 with the limiting block 203 and the sliding key shaft 207 out of contact, then press the sliding key shaft 207 or the distribution column 210, let the sliding key shaft 207 and the distribution column 210 slide in the distribution cylinder 201, and as shown, Figure 2 The left movement of the distribution column 210 is to expand the fertilizer dosage, and the right movement of the distribution column 210 is to reduce the fertilizer dosage.
[0029] The above is only a preferred embodiment of the present application, and is not used to limit the protection scope of the present application.
