[0002] During the process of agricultural planting, fertilization is an important means to promote the growth and development of crops and increase yields. However, if the fertility is excessive or insufficient, it will have an adverse impact on the growth and development of crops. Therefore, scientific fertilization is a necessary measure to improve agricultural production efficiency. And there are various ways of fertilization, and fertilization treatment can be carried out at different stages of agricultural planting.

[0003] The existing fertilization device inputs liquid fertilizer into a inserting rod inserted into the soil by squeezing the sponge that absorbs the liquid fertilizer, and fertilizes the soil. However, when the existing fertilization device is not in use, it cannot discharge the residual liquid fertilizer inside the metering cylinder, and long-term storage will contaminate the subsequent liquid fertilizer for fertilization. At the same time, it cannot drain the sponge that absorbs the liquid fertilizer, so that the sponge will be soaked in the liquid fertilizer for a long time, reducing its service life. It cannot adjust the depth inserted into the soil for fertilization, and there are limitations. Summary of the Invention

A connecting rod 205d is fixedly connected to the rear side of the sealing plate 205b. The other end of the connecting rod 205d is fixedly connected to the bottom of the transmission frame 201.

[0034] The mobile rotating assembly 206 includes sliding grooves 206a. A plurality of sliding grooves 206a are provided and are distributed at equal intervals in a ring shape. A sliding plate 206b is fixedly connected to the inner wall of the second pulley 107c. A plurality of sliding plates 206b are provided and are distributed at equal intervals in a ring shape. The sliding plate 206b is movably connected to the sliding groove 206a. A limiting ring groove 206c is formed on the outer side of the second pulley 107c. Limiting brackets 206d are fixedly connected to both sides of the front and back of the open liquid storage cylinder 103. The limiting bracket 206d is movably connected to the limiting ring groove 206c.

[0035] The partition assembly 207 includes a partition pipe 207a. The partition pipe 207a is fixedly communicated with the front of the installation pipe 114. A partition plate 207b is movably connected inside the partition pipe 207a. A connecting plate 207c is movably connected to the rear side of the right side of the open liquid storage cylinder 103. One end of the connecting plate 207c is fixedly connected to the partition plate 207b. The other end of the connecting plate 207c is fixedly connected to the transmission frame 201.

[0036] Specifically, when the electric telescopic rod 202b inside the installation groove 202a is started, it can drive the transmission frame 201 to move backward. When the transmission frame 201 moves backward, it will drive the transmission shaft 107b to move backward through the movable pin 202c. Thus, the transmission shaft 107b can drive the installation cylinder 111 to move backward through the movable bearing 204. After the installation cylinder 111 moves backward, it can drive the absorption sponge 112 to move backward. Thus, the draining plate 208 can squeeze the moving absorption sponge 112, so as to discharge the liquid fertilizer absorbed inside the absorption sponge 112.

[0037] When the fixed shaft 105 stops rotating, the bent spring 203c that is squeezed on the rotating seat 203a will push the fixed seat 203b through its own elastic force. The fixed seat 203b will drive the installation cylinder 111 to rotate under the elastic force of the bent spring 203c. Thus, after the installation cylinder 111 rotates, it can drive the absorption sponge 112 to rotate when the mobile platform 101 stops. The extrusion plate 113 can further squeeze and discharge the liquid fertilizer absorbed inside the absorption sponge 112, so as to increase the discharging effect of the liquid fertilizer absorbed inside the absorption sponge 112.

[0038] When the transmission frame 201 moves backward, it will drive the connecting rod 205d to move backward. After the connecting rod 205d moves backward, it can drive the sealing plate 205b inside the sliding frame 205c. After the sealing plate 205b moves backward, it can open the sealed drain port 205a. Thus, the residual liquid fertilizer inside the open liquid storage cylinder 103 can be discharged through the drain port 205a.

[0039] When the movable pin 202c drives the transmission shaft 107b to move backward, it will drive the sliding groove 206a to move on the surface of the sliding plate 206b, so that the second pulley 107c will not be affected by the movement of the fixed shaft 105. At the same time, the second pulley 107c will be limited by the surface limiting ring groove 206c and the limiting frame 206d, thus ensuring the stability of the second pulley 107c during rotation, and at the same time ensuring that the movement of the transmission shaft 107b will not affect the rotational stability of the second pulley 107c.

[0040] When the transmission frame 201 moves backward, it will drive the connecting plate 207c to move backward, so that the connecting plate 207c will drive the partition plate 207b inside the partition pipe 207a to move backward, and the partition plate 207b moves from inside the partition pipe 207a to inside the installation pipe 114 to partition the installation pipe 114, preventing the liquid fertilizer inside the installation pipe 114 from entering the inside of the open liquid storage cylinder 103 again.

[0041] Further, after fertilization is completed, the electric telescopic rod 202b inside the installation groove 202a is started, so that after the electric telescopic rod 202b is started, it can drive the transmission frame 201 to move backward. After the transmission frame 201 moves backward, it can drive the transmission shaft 107b to move backward through the movable pin 202c inside. After the transmission shaft 107b moves backward, it can drive the installation cylinder 111 to move backward through the movable bearing 204. After the installation cylinder 111 moves backward, it can drive the absorption sponge 112 to move backward. The absorption sponge 112 moving backward can be squeezed by the draining plate 208, so as to discharge the liquid fertilizer absorbed inside the absorption sponge 112.

[0042] When the moving platform 101 stops moving, the fixed shaft 105 will also stop rotating. When the fixed shaft 105 stops rotating, the bent spring 203c squeezed on the rotating seat 203a will push the fixed seat 203b through its own elastic force, so that the fixed seat 203b will drive the installation cylinder 111 to rotate under the elastic force of the bent spring 203c. Thus, after the installation cylinder 111 rotates, it can drive the absorption sponge 112 to rotate when the moving platform 101 stops, so that the extrusion plate 113 can further squeeze and discharge the liquid fertilizer absorbed inside the absorption sponge 112.

[0043] When the transmission frame 201 moves backward, it will drive the sealing plate 205b inside the sliding frame 205c to move backward through the connecting rod 205d. After the sealing plate 205b moves backward, it can release the sealing of the drain port 205a, so that the remaining liquid fertilizer inside the open liquid storage cylinder 103 can be discharged through the drain port 205a.

[0044] When the transmission frame 201 moves backward, it will drive the connecting plate 207c to move backward. After the connecting plate 207c moves backward, it can drive the partition plate 207b to move backward. After the partition plate 207b moves backward inside the partition pipe 207a, it can enter the inside of the installation pipe 114, so that the partition plate 207b entering the inside of the installation pipe 114 can partition the installation pipe 114, thereby preventing the liquid fertilizer in the storage tank 102 from continuously entering the open liquid storage cylinder 103 through the installation pipe 114.

[0045] When the movable pin 202c drives the transmission shaft 107b to move backward, it will drive the sliding groove 206a to move on the surface of the sliding plate 206b, so that the second pulley 107c will not be affected by the movement of the fixed shaft 105. At the same time, the second pulley 107c will be limited by the surface limit ring groove 206c and the limit frame 206d, so as to ensure the stability of the second pulley 107c during rotation, and at the same time ensure that the movement of the transmission shaft 107b will not affect the rotation stability of the second pulley 107c.

[0046] Embodiment 2 Refer to Figures 1 to 6 This is the second embodiment of the present invention, which provides a fertilizer application device for agricultural planting.

[0048] The sliding component 304 includes a sliding block 304a. The sliding block 304a is fixedly connected to the front side and the rear side of the bottom of the extrusion plate 113. The front side and the rear side of the top of the support plate 108 are both fixedly connected with sliding frames 304b. The sliding block 304a is movably connected with the sliding frame 304b.

[0049] The extrusion lifting assembly 305 includes a screw sleeve 305a fixedly connected to the left side of the bottom of the extrusion plate 113. A first threaded rod 305b is threadedly connected inside the screw sleeve 305a. The left end of the first threaded rod 305b penetrates through the left side of the support plate 108 and is movably connected to the support plate 108. A worm gear 305c is fixedly connected to the left end of the first threaded rod 305b. A worm 305d is engaged with the back surface of the worm gear 305c. A second threaded rod 305e is fixedly connected to the bottom end of the worm 305d. A threaded cylinder 305f is threadedly connected to the surface of the second threaded rod 305e. The bottom of the threaded cylinder 305f is fixedly connected to the top of the adjusting plate 301. A frustum block 305g is fixedly connected to the right end of the first threaded rod 305b. A movable sleeve block 305h is movably connected to the surface of the frustum block 305g. The bottom of the movable sleeve block 305h is fixedly connected to the top of the support plate 108.

[0050] A transmission rod A is arranged on the left side of the support plate 108. The bottom end of the transmission rod A is fixedly connected to the top of the worm 305d. A support frame B is movably connected to the surface of the transmission rod A. The right side of the support frame B is fixedly connected to the left side of the support plate 108. A rotating handwheel C is fixedly connected to the top of the transmission rod A.

[0051] Shield plates D are fixedly connected to both the front side and the rear side of the left bottom of the moving platform 101.

[0052] Specifically, when the extrusion plate 113 moves, it will drive the sliding block 304a to move inside the sliding frame 304b. Thus, the cooperation between the sliding block 304a and the sliding frame 304b can ensure the stability of the extrusion plate 113 during movement.

[0053] When it is necessary to adjust the depth of the lifting water outlet pipe 302 inserted into the soil, rotate the rotating handwheel C so that the rotating handwheel C can rotate through the transmission rod A inside the support frame B. After the transmission rod A rotates, the worm 305d can be rotated, and the rotating handwheel C can facilitate the user to rotate the worm 305d.

[0054] When the worm 305d rotates, it drives the second threaded rod 305e at the bottom to rotate. After the second threaded rod 305e rotates, it can drive the threaded cylinder 305f to move downward. After the threaded cylinder 305f moves downward, it can drive the adjusting plate 301 to move downward. When the adjusting plate 301 moves downward, it drives the lifting water outlet pipe 302 to move downward, thereby adjusting the depth of the lifting water outlet pipe 302 inserted into the soil. At the same time, when the worm 305d rotates, it drives the worm gear 305c to rotate. After the worm gear 305c rotates, it can drive the first threaded rod 305b to rotate. When the first threaded rod 305b rotates, it is limited by the conical block 305g inside the movable sleeve block 305h and drives the screw sleeve 305a to move to the right. When the screw sleeve 305a moves to the right, it drives the pressing plate 113 to move to the right. After the pressing plate 113 moves to the right, it can increase the degree of extrusion on the absorption sponge 112. Thus, the deeper the lifting water outlet pipe 302 is inserted into the soil, the higher the degree of extrusion on the absorption sponge 112, and the more liquid fertilizer can be extruded from the absorption sponge 112 after the lifting water outlet pipe 302 is inserted deeper into the soil.

[0055] At the same time, the baffle D can prevent the soil from being thrown into the support plate 108 when the grounding wheel 106 rotates.

[0056] Furthermore, when facing soil coverage with different thicknesses and depths, the user can rotate the rotary handwheel C, which drives the transmission rod A inside the support frame B to rotate. The transmission rod A drives the worm 305d to rotate. After the worm 305d rotates, it drives the second threaded rod 305e to rotate. After the second threaded rod 305e rotates, it drives the threaded cylinder 305f to move downward. After the threaded cylinder 305f moves downward, it drives the adjusting plate 301 to move downward. After the adjusting plate 301 moves downward, it drives the lifting water outlet pipe 302 to move downward on the surface of the connecting pipe 110, thereby increasing the depth of the lifting water outlet pipe 302 inserted into the soil.

[0057] When the worm 305d rotates, it drives the worm gear 305c to rotate. After the worm gear 305c rotates, it drives the first threaded rod 305b in front of the conical block 305g inside the movable sleeve block 305h to rotate. After the first threaded rod 305b rotates, it drives the screw sleeve 305a on its surface to move to the right. When the screw sleeve 305a moves to the right, it drives the pressing plate 113 to move to the right. After the pressing plate 113 moves to the right, it can further extrude the absorption sponge 112.

[0058] It should be noted that when the lifting water outlet pipe 302 moves downward, the degree of extrusion of the pressing plate 113 on the absorption sponge 112 will increase.

[0059] The rest of the structure is the same as that of Embodiment 1.

[0060] Example 3 Reference Figures 1 to 7 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is: a fertilizer application device for agricultural planting.

[0061] When facing soil coverage with different thicknesses and depths, the user can rotate the rotary handwheel C, so that the rotary handwheel C can drive the transmission rod A inside the support frame B to rotate, so that the transmission rod A can drive the worm 305d to rotate. After the worm 305d rotates, it can drive the second threaded rod 305e to rotate. After the second threaded rod 305e rotates, it can drive the threaded cylinder 305f to move downward. After the threaded cylinder 305f moves downward, it can drive the adjusting plate 301 to move downward. After the adjusting plate 301 moves downward, it can drive the lifting water outlet pipe 302 to move downward on the surface of the connecting pipe 110, thereby increasing the depth of the lifting water outlet pipe 302 inserted into the soil.

[0062] When the worm 305d rotates, it will drive the worm wheel 305c to rotate. After the worm wheel 305c rotates, it can drive the first threaded rod 305b on the front side of the conical block 305g inside the movable sleeve block 305h to rotate. After the first threaded rod 305b rotates, it can drive the nut sleeve 305a on its surface to move to the right. After the nut sleeve 305a moves to the right, it can drive the pressing plate 113 to move to the right. After the pressing plate 113 moves to the right, it can further press the absorption sponge 112.

[0063] When used by an external traction device, it will drive the moving platform 101 to move. At this time, the liquid fertilizer in the storage tank 102 will enter the open liquid storage cylinder 103 through the installation pipe 114, so that the absorption sponge 112 on the surface of the installation cylinder 111 can adsorb the liquid fertilizer in the open liquid storage cylinder 103. At the same time, when the liquid level height of the liquid fertilizer in the open liquid storage cylinder 103 is higher than the partition block 115, the sealed floating plate 116 will move upward due to buoyancy and fit with the partition plate 207b to prevent the liquid fertilizer in the open liquid storage cylinder 103 from overflowing. At the same time, when the liquid level height of the liquid fertilizer in the open liquid storage cylinder 103 is lower than the partition block 115, the sealed floating plate 116 will drop and the liquid fertilizer in the installation pipe 114 can timely supplement the open liquid storage cylinder 103.

[0064] When the mobile platform 101 moves, it drives the movable shaft frame 104 to move, enabling the movable shaft frame 104 to drive the grounding wheel 106 to move through the fixed shaft 105, allowing the grounding wheel 106 to rotate. When the grounding wheel 106 rotates, it drives the fixed shaft 105 to rotate. After the fixed shaft 105 rotates, it drives the first pulley 107a to rotate. After the first pulley 107a rotates, it drives the second pulley 107c to rotate through the transmission belt 107d. After the second pulley 107c rotates, it drives the transmission shaft 107b to rotate through the sliding plate 206b inside the sliding groove 206a. After the transmission shaft 107b rotates, it drives the rotating seat 203a to rotate. After the rotating seat 203a rotates, it squeezes the bending spring 203c and pushes the fixed seat 203b to rotate. After the fixed seat 203b rotates, it drives the mounting cylinder 111 to rotate. After the mounting cylinder 111 rotates, it drives the absorbent sponge 112 that has absorbed liquid fertilizer to rotate. After the absorbent sponge 112 that absorbs liquid fertilizer rotates, it cooperates with the pressing plate 113 that presses the absorbent sponge 112, so that the absorbed liquid fertilizer inside is squeezed by the pressing plate 113 and can flow into the support plate 108 through the pressing plate 113. The liquid fertilizer on the support plate 108 can enter the inside of the connecting pipe 110 through the diversion groove 109. After the liquid fertilizer enters the inside of the connecting pipe 110, it enters the inside of the lifting water outlet pipe 302 and is discharged through the water outlet holes 303 to fertilize the soil.

[0065] After fertilization is completed, the electric telescopic rod 202b inside the installation groove 202a is started, so that after the electric telescopic rod 202b is started, it can drive the transmission frame 201 to move backward. After the transmission frame 201 moves backward, it can drive the transmission shaft 107b to move backward through the movable pin 202c inside. After the transmission shaft 107b moves backward, it can drive the mounting cylinder 111 to move backward through the movable bearing 204. After the mounting cylinder 111 moves backward, it can drive the absorbent sponge 112 to move backward. The absorbent sponge 112 that moves backward can be squeezed by the draining plate 208, so as to discharge the liquid fertilizer absorbed inside the absorbent sponge 112.

[0066] When the mobile platform 101 stops moving, the fixed shaft 105 also stops rotating. When the fixed shaft 105 stops rotating, the bending spring 203c that is squeezed on the rotating seat 203a will push the fixed seat 203b through its own elastic force. The fixed seat 203b will be driven by the elastic force of the bending spring 203c to drive the mounting cylinder 111 to rotate. Thus, after the mounting cylinder 111 rotates, it can drive the absorbent sponge 112 to rotate when the mobile platform 101 stops, so that the pressing plate 113 can further squeeze and discharge the absorbed liquid fertilizer inside the absorbent sponge 112.

[0067] While the transmission frame 201 moves backward, it drives the sealing plate 205b inside the sliding frame 205c to move backward through the connecting rod 205d. After the sealing plate 205b moves backward, it can release the sealing of the drain port 205a, so that the remaining liquid fertilizer inside the open liquid storage cylinder 103 can be discharged through the drain port 205a.

[0068] When the transmission frame 201 moves backward, it drives the connecting plate 207c to move backward. After the connecting plate 207c moves backward, it can drive the partition plate 207b to move backward. After the partition plate 207b moves backward inside the partition pipe 207a, it can enter the inside of the installation pipe 114, so that the partition plate 207b entering the inside of the installation pipe 114 can partition the installation pipe 114, thus preventing the liquid fertilizer inside the storage tank 102 from continuously entering the open liquid storage cylinder 103 through the installation pipe 114.

[0069] When the movable pin 202c drives the transmission shaft 107b to move backward, it drives the sliding groove 206a to move on the surface of the sliding plate 206b, so that the second pulley 107c is not affected by the movement of the fixed shaft 105. At the same time, the second pulley 107c is limited by the surface limit ring groove 206c and the limit frame 206d, thus ensuring the stability of the second pulley 107c during rotation and ensuring that the movement of the transmission shaft 107b does not affect the rotation stability of the second pulley 107c.

[0070] In summary, through the extrusion lifting component 305 inside the extrusion depth adjustment mechanism 300, the amount of liquid fertilizer for fertilization can be adjusted according to the depth of the lifting water outlet pipe 302 inserted into the soil. At the same time, the moving component 202 inside the drainage partition mechanism 200 can cooperate with the drainage plate 208 to drain the absorption sponge 112, and the discharge component 205 and the partition component 207 can be used to prevent liquid fertilizer from remaining inside the open liquid storage cylinder 103.
