The fertilizer in each discharge pipe can flow into the corresponding corrugated hose. The fertilizer entering the corrugated hose will flow out through the discharge head. When it is necessary to adjust the fertilization spacing, the two sets of threaded adjustment structures are rotated respectively. When the two sets of threaded adjustment structures move outward, they will pull the movement of the two discharge heads on the outer edge respectively. When the two discharge heads on the outer edge move, they will synchronously drive the movement of multiple discharge heads on the outer edge through the telescopic pulling structure formed by the first connecting piece and the second connecting piece. When the multiple discharge heads on the outer edge are moving, the fertilizer applicator can freely adjust the fertilization spacing.

[0042] Fifth, in this utility model, the vibrating material structure can continuously vibrate or shake as the fertilizer applicator moves, and during the vibration or shaking process of the vibrating material structure, it can assist in the discharge of fertilizer.

[0043] VI. In this utility model, because the fertilizer applicator will traverse uneven terrain during its mobile fertilization process, it will constantly bounce. During this bouncing process, such as... Figure 5 As shown, each vibrating slider in the vibrating structure slides up and down on its corresponding guide rod. When each vibrating slider slides down, the spring below the vibrating slider will use its own elasticity to give the vibrating slider an upward reaction force, causing the vibrating slider to slide up again. This process is repeated, so that it can vibrate and shake the material in the inner cavity of the fertilizer box.

[0044] Meanwhile, the limiting block on each guide slide rod can prevent the vibration material sliding block from slipping off.

[0045] Seven, the foldable support leg structure can be folded, when the fertilizer applicator is idle, the foldable support leg structure is supported, so that the fertilizer applicator can be placed horizontally, when the fertilizer applicator is used, the foldable support leg structure can be folded and stored.

[0046] Eight, the iron support leg can be folded in the direction of the inner side, after folding, the iron support leg can be fixed by the suction accessory, the iron support leg can be turned over on the inverted U-shaped base, under the limiting action of the limiting baffle, the iron support leg can be in a vertical state after turning over, which facilitates supporting the fertilizer applicator, when turning over upward, the iron support leg can be fixed by the suction accessory.

[0066] When the fertilizer flows out of each discharge pipe 80, the discharge amount of the fertilizer of each discharge pipe 80 can be adjusted by rotating each discharge adjusting valve 90, so that the fertilizer machine has the function of adjusting the discharge amount of the fertilizer;

[0067] The spacing-adjustable discharge mechanism 100 is arranged on one side of the plurality of discharge pipes 80;

[0068] The spacing-adjustable discharge mechanism 100 comprises a plurality of corrugated hoses 1001 corresponding to the discharge pipes 80, one end of each corrugated hose 1001 is insertedly installed in the corresponding discharge pipe 80, and the other end of each corrugated hose 1001 is sleevedly installed with a discharge head 1002;

[0075] As shown in Figures 1-10 , the embodiment is improved on the basis of the first embodiment:

[0076] In order to optimize the specific structure of the two sets of threaded adjusting structures, in the embodiment, further, as shown in Figures 6-7 , each set of threaded adjusting structure includes an internally threaded sleeve 1007.

[0079] In order to be able to support and fix the U-shaped base 1003, in this embodiment, further, the spacing adjusting type discharging mechanism 100 further comprises a support 1009, which is fixedly installed on one side of the bottom of the U-shaped base 1003, and one end of the support 1009 is fixedly connected with the side wall of the bottom disc 10, and the support 1009 is used to support and fix the U-shaped base 1003.

[0080] Embodiment three

[0081] As shown in Figures 1-10 , the improvement is based on embodiment one:

[0082] In order to optimize the flow guiding effect of the wedge-shaped guide plate 70, in this embodiment, further, as shown in Figure 4 , the top of the wedge-shaped guide plate 70 has a guide slope 701;

[0083] The bottom end of each discharge pipe 80 is tangent to the bottom of the guide slope 701, and when the bottom end of each discharge pipe 80 is tangent to the bottom of the guide slope 701, the fertilizer in the fertilizer bin 50 can better flow into each discharge pipe 80.

[0084] Embodiment four

[0085] As shown in Figures 1-10 , the improvement is based on embodiment one:

[0086] In order to make the fertilizer in the fertilizer applicator better discharge, in this embodiment, further, as shown in Figure 1 and Figures 3-5 , a vibrating structure 110 is installed in the inner cavity of the fertilizer bin 50, which can continuously vibrate or shake with the movement of the fertilizer applicator, and can assist the discharge of the fertilizer during the vibration or shaking of the vibrating structure 110.

[0087] More specifically, as shown in Figure 1 and Figures 3-5As shown, the vibrating material structure 110 includes a crossbeam 1101, which is fixedly installed in the middle of the inner cavity of the fertilizer box 50. Multiple guide slide rods 1102 are fixedly installed on the top of the crossbeam 1101, and the multiple guide slide rods 1102 are equidistantly distributed along the length direction of the crossbeam 1101.

[0088] Each guide slide bar 1102 is slidably mounted with a vibrating slider 1103;

[0089] Each guide slide bar 1102 is fitted with a spring 1104, and each spring 1104 is located between the vibrating slider 1103 and the crossbeam 1101;

[0090] Each guide slide bar 1102 is fixedly installed with a limit block 1105 at its top. Because the fertilizer applicator will traverse uneven terrain during its movement, it will constantly bump and vibrate. During this bumping process, such as... Figure 5 As shown, each vibrating slider 1103 in the vibrating structure 110 slides up and down on the corresponding guide rod 1102. When each vibrating slider 1103 slides down, the spring 1104 below the vibrating slider 1103 will use its own elasticity to give the vibrating slider 1103 an upward reaction force, causing the vibrating slider 1103 to slide up again. This process is repeated, so that it can vibrate and shake the material in the inner cavity of the fertilizer box 50.

[0091] Meanwhile, the limiting block 1105 on each guide slide 1102 can prevent the vibrating slider 1103 from slipping off.

[0092] Example 5

[0093] like Figures 1-10 As shown, improvements are made based on Example 2:

[0094] In order to better facilitate the placement of the fertilizer applicator when it is not in use, in this embodiment, further, as... Figures 8-10 As shown, a foldable support leg structure 120 is also installed on the bracket 1009. The foldable support leg structure 120 can be folded up. When the fertilizer applicator is idle, the foldable support leg structure 120 can be raised up so that the fertilizer applicator can be placed horizontally. When the fertilizer applicator is in use, the foldable support leg structure 120 can be folded up.

[0095] More specifically, such as Figures 8-10 As shown, the foldable support leg structure 120 includes an inverted U-shaped base 1201, which is fixedly installed in the middle of the bottom outer side of the bracket 1009. An iron support leg 1202 is movably installed on the inverted U-shaped base 1201 via a pin.

[0096] A limit baffle 1203 is fixedly installed on one outer end of the inverted U-shaped base 1201;

[0097] The bottom of the bracket 1009 is equipped with an adsorption component. The iron support leg 1202 can be folded inward. After folding, the iron support leg 1202 can be fixed by the adsorption component. The iron support leg 1202 can move and rotate on the inverted U-shaped base 1201. Under the limiting action of the limiting baffle 1203, the iron support leg 1202 can be in a vertical state after being rotated. This state is convenient for supporting the fertilizer applicator. When it is rotated upward, the iron support leg 1202 can be fixed by the adsorption component again.

[0098] More specifically, such as Figures 8-10 As shown, the adsorption component is a magnet block 1204, which is fixedly installed at the bottom center of the bracket 1009.

[0099] When the iron support leg 1202 is folded inward, it can be attracted and fixed by the magnet block 1204.

[0100] More specifically, such as Figure 10 As shown, the swing amplitude of the iron support leg 1202 is 90°.

[0101] In summary, the workflow of this utility model is as follows:

[0102] like Figures 1-10 As shown, the fertilizer in the fertilizer bin 50 flows into each discharge pipe 80 through the guiding action of the wedge-shaped guide plate 70. The fertilizer in each discharge pipe 80 can flow into the corresponding corrugated hose 1001. The fertilizer entering the corrugated hose 1001 will flow out through the discharge head 1002. When it is necessary to adjust the fertilization spacing, by rotating the two sets of threaded adjustment structures respectively, the two sets of threaded adjustment structures will pull the two discharge heads 1002 on the outer edge respectively when they move outward. When the two discharge heads 1002 on the outer edge move, they will synchronously drive the movement of multiple discharge heads 1002 on the outer edge through the telescopic pulling structure formed by the first connecting piece 1004 and the second connecting piece 1005. When the multiple discharge heads 1002 on the outer edge are moving, the fertilizer applicator can freely adjust the fertilization spacing.

[0103] More specifically, in the fertilizer applicator, the U-shaped base 1003 is used to support and fix a plurality of discharge heads 1002, and the discharge head 1002 in the middle position can be fixed and limited by the arc-shaped fixing groove 10031, so that it remains unchanged in the middle position, while the plurality of discharge heads 1002 on the outside can slide on the upper surface of the U-shaped base 1003 when moving in cooperation between the corresponding threaded adjusting structure and the telescopic pulling structure, and the plurality of discharge heads 1002 on the outside can realize synchronous sliding under the action of each set of telescopic pulling structure during the sliding process. Therefore, when the discharge head 1002 in the middle position remains unchanged, and the plurality of discharge heads 1002 on the outside synchronously slide, the fertilizer spacing of the fertilizer applicator can be randomly and freely adjusted.

[0104] In addition, after the fertilizer flows out of each discharge pipe 80, the fertilizer discharge amount of each discharge pipe 80 can be adjusted by rotating each discharge adjusting valve 90, so that the fertilizer applicator has the function of adjusting the fertilizer discharge amount.

[0105] Specifically, the threaded rod 1008 can convert rotary motion into linear motion under the cooperation of the threads of the inner threaded sleeve 1007 and the threaded rod 1008. When the threaded rod 1008 moves linearly, since each threaded rod 1008 is rotatably installed on the corresponding rotating base 1006 at one end towards the corresponding rotating base 1006 through the limiting ring, the threaded rod 1008 can drive the movement of the discharge head 1002 on the outer edge when it moves.

[0106] The wedge-shaped guide plate 70 is used to guide the flow of fertilizer in the fertilizer bin 50. The bottom end of each discharge pipe 80 is tangent to the bottom of the guide slope 701. When the bottom end of the discharge pipe 80 is tangent to the bottom of the guide slope 701, the fertilizer in the fertilizer bin 50 can better flow into each discharge pipe 80.

[0107] The vibrating structure 110 can continuously vibrate or shake with the movement of the fertilizer applicator. During the vibration or shaking of the vibrating structure 110, it can assist the discharge of the fertilizer.

[0108] Specifically, since the fertilizer applicator will pass through the bumpy terrain during the movement of the fertilizer, the fertilizer applicator will continuously bump, and during the bumping of the fertilizer applicator, the fertilizer in the fertilizer bin 50 will be continuously shaken and vibrated, which can assist the discharge of the fertilizer. Figure 5As shown, each of the material vibrating sliders 1103 in the material vibrating structure 110 slides up and down on the corresponding guide slide rod 1102, and when each of the material vibrating sliders 1103 slides downward, the spring 1104 below the material vibrating slider 1103 provides an upward reaction force to the material vibrating slider 1103 by virtue of its elasticity, so that the material vibrating slider 1103 slides upward again, and the process is repeated, so that the material vibrating slider 1103 can vibrate and shake the fertilizer in the inner cavity of the fertilizer bin 50.

[0109] Meanwhile, the limiting block 1105 on each of the guide slide rods 1102 can prevent the material vibrating slider 1103 from sliding off.

[0110] The foldable support leg structure 120 can be folded, and when the fertilizer applicator is idle, the foldable support leg structure 120 is erected, so that the fertilizer applicator can be placed horizontally, and when the fertilizer applicator is used, the foldable support leg structure 120 can be folded and stored.
