Description

Technical Field

[0001] The invention belongs to the field of planting equipment technology, and more specifically relates to a fertilizing device. Background Art

[0002] The fertilization device is mainly used for ring ditch fertilization of bayberry trees. The ring ditch fertilization method mainly opens a ring ditch near the drip line along the outer periphery of the tree crown. Fertilizing near the drip line can enhance the fertilizer release effect, allowing rainwater to fall along the drip line to wet the fertilizer. The width and depth of the ditch depend on the type and quantity of the fertilizer. Generally, the ditch is 20 cm wide and about 30 cm deep. The fertilizer is placed in the ring ditch, and the soil is backfilled to complete the fertilization operation. The ring ditch fertilization allows the fertilizer to be released evenly to avoid damaging the tree roots.

[0003] The patent document with announcement number CN222465302U records an agricultural planting fertilization device, including a fixed frame, a central shaft with a rotation connection is inserted into the fixed frame, a first synchronous wheel is fixedly installed at one end of the central shaft, and a second synchronous wheel is fixedly installed at the other end of the central shaft. The fixed frame is fixedly installed with a sowing shell, and the sowing shell is sleeved outside the central shaft and is rotationally connected thereto. The device uses two blocking blocks, and the movement of the blocking blocks can increase or decrease the area for holding fertilizer, thereby controlling the amount of fertilizer discharged each time. At the same time, a trench for holding fertilizer is dug using a furrowing plow, and then the soil is frequently covered and compacted using a pressing block, so that the fertilizer remains stably buried beside the seeds, thereby ensuring the normal fertility of the fertilizer. The device is simple to install and evenly sown.

[0004] The above-mentioned fertilization device has certain shortcomings when performing ring ditch fertilization operations on bayberry trees. Because ring ditch fertilization is used to fertilize bayberry trees, it is necessary to open a ring groove according to the size of the bayberry tree's crown, and the fertilization device cannot be suitable for ring movement, which makes it easy for the grooves to be misaligned when docking. The depth and accuracy of the ring groove opened by it cannot meet the requirements of fertilization. It does not have a ring movement auxiliary structure and cannot be flexibly applied to bayberry trees of different calibers. Summary of the invention

[0005] The purpose of the present invention is to provide a fertilizing device which can solve the existing problems.

[0006] The problem to be solved by the present invention is:

[0007] 1. Because the ring ditch fertilization is used to fertilize the bayberry tree, it is necessary to open a ring groove according to the size of the bayberry tree crown, but the fertilization device cannot be used for ring movement, which makes it easy to misalign when the notch is docked. The depth and accuracy of the ring groove cannot meet the requirements of fertilization. It does not have a ring movement auxiliary structure and cannot be flexibly applied to bayberry trees of different calibers:

[0008] A fertilization device comprises a fertilizer applicator, a fixed base and a limit rod, wherein the fertilizer applicator is fixedly mounted on the outer surface of the lower end of the fixed base, a docking socket is fixedly mounted on the outer surface of the upper end of the fixed base, and the limit rod is movably mounted on the front end of the docking socket, the fertilizer applicator comprises a discharge pipe, a lifting sleeve and a soil-breaking cone, the lifting sleeve is movably sleeved on the inner side of the lower end of the discharge pipe, the soil-breaking cone is elastically mounted on the outer surface of the lower end of the lifting sleeve, and one end of the soil-breaking cone is an arc-shaped pointed cone structure, a telescopic rod is movably mounted on one end of the limit rod, and a fixed clamp is movably mounted on the end of the telescopic rod, and four groups of limit clamps for limiting the trunk of a bayberry tree are arranged on the inner side of the fixed clamp.

[0009] As a further technical solution of the present invention, a feed roller is movably installed in the middle position of the inner side of the docking base, and a driving wheel is movably installed at one end of the fixed base. The driving wheel and the feed roller are driven by a gear-coordinated transmission chain. When the user pushes the fertilization device to move, the driving wheel rotates, and the gear-coordinated transmission chain is utilized to make the driving wheel drive the feed roller to rotate. The rotation of the feed roller is utilized to complete the discharge of the fertilizer, and the fertilizer is discharged into the fertilizer applicator and discharged downward through the fertilizer applicator.

[0010] As a further technical solution of the present invention, a fertilizer box is spliced ​​and installed on the outer surface of the upper end of the docking card seat, and the docking card seat and the fertilizer box are spliced ​​and fixed by a docking card strip. The upper end of the docking card seat is provided with a bar slot used in conjunction with the docking card strip. The user fills the interior of the fertilizer box with fertilizer, and connects the bar slot with the docking card strip, so that the fertilizer box is spliced ​​and installed on the upper end of the docking card seat, so that the discharge port of the fertilizer box and the feed roller are docked with each other.

[0011] As a further technical solution of the present invention, a lifting seat is fixedly installed at the rear end of the docking seat, and a backfilling plate is movably installed at the lower part of the lifting seat. The front end of the backfilling plate is a V-shaped structure, and a push-pull plate is fixedly installed at the rear end of the backfilling plate. After the fertilizer spreader completes the circular trenching operation, the soil on both sides of the circular groove can be pushed by the backfilling plate during the fertilizer spreading process of the fertilizer spreader, so that the soil is backfilled into the circular groove to complete the backfilling operation. The V-shaped structure allows the backfilling plate to gather the soil towards the middle when it contacts the soil, thereby gathering the soil.

[0012] As a further technical solution of the present invention, a lifting block for fixing the telescopic rod is movably installed on one side of the limit rod, and the surfaces of the lifting block and the telescopic rod are provided with toothed grooves. One end of the limit rod and the fixed clamping ring are movably connected via a rotating clamping seat. The user uses the bolt body to adjust the position of the lifting block so that the toothed grooves of the lifting block and the telescopic rod are butted against each other, thereby fixing the telescopic rod. The rotating clamping seat makes the limit rod and the fixed clamping ring movable, and the angle of the rotating clamping seat can be adjusted when the limit rod is vertically retracted to avoid the rotating clamping seat being stuck on one side of the fertilizer box.

[0013] As a further technical solution of the present invention, the fixed clamp is composed of two groups of semicircular rings, and one end of the fixed clamp is movably connected by a rotating rod, and the other end of the fixed clamp is fixed by a fixing buckle. During operation, in order to improve the accuracy of the circular movement of the fertilizing device, a fixed clamp is set, and the two groups of semicircular rings are opened by the rotating rod, and the two groups of semicircular rings are closed on the surface of the trunk. The two groups of semicircular rings are fixed by the fixing buckle, and the fixed clamp fixes the trunk. According to the outer distance of the crown, the fertilizing device is adjusted to the corresponding position by the lifting block and the telescopic rod, and the push handle is pushed, so that the fertilizing device drives the fertilizer applicator under the action of the driving wheel and the rear wheel body, so that the fertilizer applicator moves in a circular shape around the trunk.

[0014] As a further technical solution of the present invention, the limit clamp includes a telescopic sleeve and a telescopic column, the telescopic column is movably installed on the inner side of the telescopic sleeve, and a positioning clamp wheel is movably installed on one end of the telescopic column, the telescopic sleeve and the telescopic column are driven by an adjusting bolt, and the setting of the limit clamp allows the fixed clamp ring to meet the fixing operation of tree trunks of different calibers. During operation, the adjusting bolt is rotated so that the adjusting bolt drives the telescopic column using a threaded structure, so that the telescopic column is moved out of the telescopic sleeve, thereby adjusting the use position of the positioning clamp wheel, and four groups of positioning clamp wheels are used to fix the surface of the trunk. When the fertilization device moves in a circle around the trunk, the fixed clamp ring rotates on the surface of the trunk, so that the four groups of positioning clamp wheels rotate on the surface of the trunk, which can avoid damaging the trunk.

[0015] As a further technical solution of the present invention, the lifting sleeve and the ground-breaking cone are elastically connected by an elastic clamp, a spring is provided on the inner side of the elastic clamp, the interior of the ground-breaking cone is a hollow structure, and a discharge port is provided at the bottom of the ground-breaking cone. In order to improve the use effect of the ground-breaking cone, the spring structure of the elastic clamp is utilized to make the lifting sleeve and the ground-breaking cone elastically connected. When the ground-breaking cone moves, the ground-breaking cone and the soil can be in close contact to avoid the formation of gaps therebetween.

[0016] As a further technical solution of the present invention, a positioning groove is provided on the surface of the lifting sleeve, a bolt is provided on the surface of the discharge pipe for cooperating with the positioning groove, and a flow control valve is provided on the inner side of the discharge pipe. The depth of the annular groove is thirty centimeters. A single annular movement of the soil-breaking cone of the fertilizer applicator cannot complete a groove with a depth of thirty centimeters at one time. Therefore, each time the soil-breaking cone moves in a circle, the soil-breaking cone is moved downward a certain distance by the lifting sleeve to increase the groove depth of the soil-breaking cone. After multiple annular movements, the depth of the soil-breaking cone is thirty centimeters, thereby reducing the difficulty of grooving the soil-breaking cone.

[0017] As a further technical solution of the present invention, a rear wheel body is movably mounted on the rear end of the fixed base, a push handle is fixedly mounted on the upper part of the fixed base, and the inner bottom of the fertilizer box is an inclined structure.

[0018] Beneficial effects of the present invention:

[0019] 1. By setting a limit rod and a fixed clamp ring, when the fertilizing device is used, the fertilizing device can move in a circular shape around the bayberry tree trunk according to the size of the tree crown, complete the grooving operation of its annular groove, and improve the fertilization effect of the annular groove;

[0020] During operation, first adjust the use length of the telescopic rod according to the size of the tree crown. The user uses the bolt to adjust the position of the lifting block so that the lifting block and the toothed slots of the telescopic rod are connected to each other, thereby fixing the telescopic rod. The rotating clamp makes the limit rod and the fixed clamp ring movable. When the limit rod is vertically recovered, the angle of the rotating clamp can be adjusted to avoid the rotating clamp being stuck on one side of the fertilizer box. In order to improve the accuracy of the fertilization device during circular movement, a fixed clamp ring is set and used to dock the surface of the tree trunk. The two groups of semicircular rings are opened by the rotating rod, and the two groups of semicircular rings are closed on the surface of the tree trunk. The two groups of semicircular rings are fixed by the fixing buckle, and the fixing clamp ring fixes the tree trunk. According to the outer distance of the crown, the fertilizer device is adjusted to the corresponding position by the lifting block and the telescopic rod, and the push handle is pushed so that the fertilizer device drives the fertilizer applicator under the action of the driving wheel and the rear wheel body. The limiting rod and the telescopic rod are used to make the fertilizer applicator move in a circular shape around the tree trunk. When the fertilizer applicator moves, the soil-breaking cone completes the circular groove, which is convenient for it to perform the ring groove fertilization operation;

[0021] At the same time, in order to avoid damaging the tree trunk during circular movement and to be suitable for tree trunk structures of different calibers, a limit clamp is set to improve the use effect of the fixed clamp ring. The setting of the limit clamp allows the fixed clamp ring to meet the fixing operation of tree trunks of different calibers. During operation, the adjusting bolt is rotated so that the adjusting bolt drives the telescopic column using the threaded structure to move the telescopic column out of the telescopic sleeve, thereby adjusting the use position of the positioning clamp wheel. Four groups of positioning clamp wheels are used to fix the surface of the trunk. When the fertilization device moves in a circle around the trunk, the fixed clamp ring rotates on the surface of the trunk, causing the four groups of positioning clamp wheels to rotate on the surface of the trunk, thereby avoiding damage to the trunk.

[0022] 2. By setting a fertilizer applicator, when the fertilizer applicator is used, the annular grooving effect is improved and the difficulty of the annular grooving is reduced;

[0023] When in use, the groove depth of the ring ditch fertilization of bayberry trees needs to reach 30 centimeters. The groove depth is relatively deep, and the conventional fertilization device cannot meet the ground-breaking operation of 30 centimeters deep in a single movement. By setting a fertilizer applicator, the ground-breaking cone is moved down a certain distance by the lifting sleeve every time the ground-breaking cone moves in a circle. Each time it moves ten centimeters, the groove depth of the ground-breaking cone is gradually increased. After multiple circular movements, the depth of the ground-breaking cone is 30 centimeters, thereby reducing the difficulty of groove opening of the ground-breaking cone. The positioning groove is used in conjunction with the clamping bolt structure to fix the lifting sleeve after movement. In order to improve the use effect of the ground-breaking cone, the spring structure of the elastic clamp is used to make the lifting sleeve and the ground-breaking cone elastically connected. When the ground-breaking cone moves, the ground-breaking cone and the soil can be in close contact to avoid gaps.

[0024] 3. By setting the backfill plate and the feed roller, when the fertilization device is used, it can simultaneously complete the fertilization and soil backfilling operations, thereby improving its working efficiency, quantitatively applying fertilizer according to the size of the annular groove, and improving its fertilization effect;

[0025] During operation, the user fills the interior of the fertilizer box with fertilizer, and connects the bar-shaped slot through the docking card strip to make the fertilizer box spliced ​​and installed on the upper end of the docking card seat, so that the discharge port of the fertilizer box and the feed roller are docked with each other. When the user pushes the fertilization device to move, the driving wheel rotates, and the gear cooperates with the transmission chain to make the driving wheel drive the feed roller to rotate. The rotation of the feed roller is used to complete the top material discharge of the fertilizer, and the fertilizer is discharged into the fertilizer spreader and discharged downward through the fertilizer spreader. During the fertilizer spreading process of the fertilizer spreader, the soil on both sides of the annular groove is pushed by the backfilling plate, so that the soil is backfilled into the annular groove to complete the backfilling operation. The V-shaped structure makes the backfilling plate gather the soil to the middle when it contacts the soil, thereby playing a role in gathering the soil. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0038] like Figure 1-9 As shown, a fertilizing device includes a fertilizer applicator 2, a fixed base 9 and a limiting rod 8. The fertilizer applicator 2 is fixedly mounted on the outer surface of the lower end of the fixed base 9, and a docking card seat 5 is fixedly mounted on the outer surface of the upper end of the fixed base 9, and the limiting rod 8 is movably mounted on the front end of the docking card seat 5. The fertilizer applicator 2 includes a discharge pipe 28, a lifting sleeve 27 and a soil-breaking cone 31. The lifting sleeve 27 is movably sleeved on the inner side of the lower end of the discharge pipe 28, and the soil-breaking cone 31 is elastically mounted on the outer surface of the lower end of the lifting sleeve 27, and one end of the soil-breaking cone 31 is an arc-shaped pointed cone structure. A telescopic rod 19 is movably mounted on one end of the limiting rod 8, and a fixed clamping ring 15 is movably mounted on the end of the telescopic rod 19. Four groups of limiting clamps 16 for limiting the trunk of the bayberry tree are arranged on the inner side of the fixed clamping ring 15.

[0039] like Figure 2 As shown, a feed roller 14 is movably installed at the middle position of the inner side of the docking base 5, and a driving wheel 1 is movably installed at one end of the fixed base 9. The driving wheel 1 and the feed roller 14 are driven by a gear-coordinated transmission chain 10. When the user pushes the fertilizing device to move, the driving wheel 1 rotates, and the gear-coordinated transmission chain 10 is used to make the driving wheel 1 drive the feed roller 14 to rotate. The rotation of the feed roller 14 is used to complete the discharge of the fertilizer, and the fertilizer is discharged into the fertilizer applicator 2 and discharged downward through the fertilizer applicator 2.

[0040] A fertilizer box 6 is spliced ​​and installed on the outer surface of the upper end of the docking card seat 5. The docking card seat 5 and the fertilizer box 6 are spliced ​​and fixed by a docking card strip 13. The upper end of the docking card seat 5 is provided with a strip card slot 12 used in conjunction with the docking card strip 13. The user fills the interior of the fertilizer box 6 with fertilizer, and connects the strip card slot 12 with the docking card strip 13, so that the fertilizer box 6 is spliced ​​and installed on the upper end of the docking card seat 5, so that the discharge port of the fertilizer box 6 and the feed roller 14 are docked with each other.

[0041] To solve the soil backfill problem, such as Figure 8 As shown, a lifting card seat 11 is fixedly installed at the rear end of the docking card seat 5, and a backfilling plate 3 is movably installed at the lower part of the lifting card seat 11. The front end of the backfilling plate 3 is a V-shaped structure, and a push-pull plate 32 is fixedly installed at the rear end of the backfilling plate 3. After the fertilizer spreader 2 completes the annular trenching operation, the soil on both sides of the annular groove can be pushed by the backfilling plate 3 during the fertilizer spreading process of the fertilizer spreader 2, so that the soil is backfilled into the annular groove to complete the backfilling operation. The setting of the V-shaped structure makes the backfilling plate 3 gather the soil to the middle when it contacts the soil, thereby playing a role in gathering the soil.

[0042] To solve the problem of circular fertilization of fertilization device, such as Figure 4 As shown, a lifting block 18 for fixing the telescopic rod 19 is movably installed on one side of the limit rod 8, and the surfaces of the lifting block 18 and the telescopic rod 19 are provided with toothed grooves. One end of the limit rod 8 and the fixed clamping ring 15 are movably connected through a rotating clamping seat 21. The user uses the bolt to adjust the position of the lifting block 18 so that the toothed grooves of the lifting block 18 and the telescopic rod 19 are butted against each other, thereby fixing the telescopic rod 19. The rotating clamping seat 21 makes the limit rod 8 and the fixed clamping ring 15 movable. When the limit rod 8 is vertically recovered, the angle of the rotating clamping seat 21 can be adjusted to avoid the rotating clamping seat 21 being stuck on one side of the fertilizer box 6.

[0043] like Figure 5As shown, the fixed clamp 15 is composed of two groups of semicircular rings, and one end of the fixed clamp 15 is movably connected by a rotating rod 20, and the other end of the fixed clamp 15 is fixed by a fixing buckle 17. During operation, in order to improve the accuracy of the circular movement of the fertilizing device, the fixed clamp 15 is set, and the two groups of semicircular rings are opened by the rotating rod 20, and the two groups of semicircular rings are closed on the surface of the trunk, and the two groups of semicircular rings are fixed by the fixing buckle 17. The fixed clamp 15 fixes the trunk, and according to the outer distance of the crown, the fertilizing device is adjusted to the corresponding position by the lifting block 18 and the telescopic rod 19, and the push handle 7 is pushed, so that the fertilizing device drives the fertilizer applicator 2 under the action of the driving wheel 1 and the rear wheel body 4, so that the fertilizer applicator 2 moves in a circular shape around the trunk.

[0044] like Figure 6 As shown, the limit clamp 16 includes a telescopic sleeve 23 and a telescopic column 24, the telescopic column 24 is movably installed on the inner side of the telescopic sleeve 23, and a positioning clamp wheel 25 is movably installed at one end of the telescopic column 24, the telescopic sleeve 23 and the telescopic column 24 are driven by the adjusting bolt 22, and the setting of the limit clamp 16 allows the fixed clamp ring 15 to meet the fixing operation of tree trunks with different calibers. During operation, by rotating the adjusting bolt 22, the adjusting bolt 22 drives the telescopic column 24 by the threaded structure, so that the telescopic column 24 is moved out of the telescopic sleeve 23, thereby adjusting the use position of the positioning clamp wheel 25, and using four groups of positioning clamp wheels 25 to fix the surface of the trunk. When the fertilizing device moves around the trunk in a circle, the fixed clamp ring 15 rotates on the surface of the trunk, so that the four groups of positioning clamp wheels 25 rotate on the surface of the trunk, which can avoid damaging the trunk.

[0045] like Figure 7 As shown, the lifting sleeve 27 and the ground-breaking cone 31 are elastically connected by an elastic clamp 30. A spring is provided on the inner side of the elastic clamp 30. The interior of the ground-breaking cone 31 is a hollow structure, and a discharge port is provided at the bottom of the ground-breaking cone 31. In order to improve the use effect of the ground-breaking cone 31, the spring structure of the elastic clamp 30 is utilized to make the lifting sleeve 27 and the ground-breaking cone 31 elastically connected. When the ground-breaking cone 31 moves, the ground-breaking cone 31 can be in close contact with the soil to avoid a gap therebetween.

[0046] A positioning groove 26 is provided on the surface of the lifting sleeve 27, a bolt used in conjunction with the positioning groove 26 is provided on the surface of the discharge pipe 28, and a flow control valve 29 is provided on the inner side of the discharge pipe 28. The annular groove depth is thirty centimeters. A single annular movement of the soil-breaking cone 31 of the fertilizer spreader 2 cannot complete a groove with a depth of thirty centimeters at one time. Therefore, each time the soil-breaking cone 31 moves in an annular manner, the soil-breaking cone 31 is moved downward a certain distance by the lifting sleeve 27 to increase the groove depth of the soil-breaking cone 31. After multiple annular movements, the depth of the soil-breaking cone 31 is thirty centimeters, thereby reducing the difficulty of groove opening of the soil-breaking cone 31.

[0047] A rear wheel body 4 is movably mounted on the rear end of the fixed base 9, a push handle 7 is fixedly mounted on the upper portion of the fixed base 9, and the inner bottom of the fertilizer box 6 is in an inclined structure.

[0048] During use, because the ring ditch fertilization is used to fertilize the bayberry tree, it is necessary to open a ring groove according to the size of the bayberry tree crown, and the fertilization device cannot be used for ring movement, so that the misalignment phenomenon is easy to occur when the grooves are connected. The depth and accuracy of the ring groove opened by the device cannot meet the requirements of fertilization. It does not have a ring movement auxiliary structure and cannot be flexibly applied to bayberry trees of different calibers.

[0049] To this end, by setting the limit rod 8 and the fixed clamp ring 15, when the fertilizing device is used, the fertilizing device can be moved in a ring shape around the bayberry trunk according to the size of the tree crown, complete the grooving operation of its annular groove, and improve the fertilization effect of the annular groove;

[0050] During operation, the length of the telescopic rod 19 is first adjusted according to the size of the tree crown. The user uses the bolt to adjust the position of the lifting block 18 so that the toothed grooves of the lifting block 18 and the telescopic rod 19 are butted against each other, thereby fixing the telescopic rod 19. The rotating clamp 21 makes the limit rod 8 and the fixed clamp ring 15 movable. When the limit rod 8 is vertically recovered, the angle of the rotating clamp 21 can be adjusted to prevent the rotating clamp 21 from being stuck on one side of the fertilizer box 6. In order to improve the accuracy of the fertilizing device during circular movement, the fixed clamp ring 15 is provided and used to dock the tree The two groups of semicircular rings are opened by the rotating rod 20, and the two groups of semicircular rings are closed on the surface of the trunk. The two groups of semicircular rings are fixed by the fixing buckle 17, and the fixing clamp 15 fixes the trunk. According to the outer distance of the crown, the fertilizer device is adjusted to the corresponding position by the lifting block 18 and the telescopic rod 19, and the push handle 7 is pushed, so that the fertilizer device drives the fertilizer applicator 2 under the action of the driving wheel 1 and the rear wheel body 4. The limiting rod 8 and the telescopic rod 19 are used to make the fertilizer applicator 2 move in a ring shape around the trunk. When the fertilizer applicator 2 moves, the soil breaking cone 31 completes the ring groove, which is convenient for it to perform the ring groove fertilization operation;

[0051] At the same time, in order to avoid damaging the tree trunk during circular movement and to be applicable to tree trunk structures of different calibers, a limiting clamp 16 is provided to improve the use effect of the fixing clamp 15. The setting of the limiting clamp 16 enables the fixing clamp 15 to meet the fixing operation of tree trunks of different calibers. During operation, the adjusting bolt 22 is rotated so that the adjusting bolt 22 drives the telescopic column 24 using the threaded structure, so that the telescopic column 24 is moved out of the telescopic sleeve 23, thereby adjusting the use position of the positioning clamp wheel 25. The four groups of positioning clamp wheels 25 are used to fix the surface of the tree trunk. When the fertilizing device moves in a circular manner around the tree trunk, the fixing clamp ring 15 rotates on the surface of the tree trunk, so that the four groups of positioning clamp wheels 25 rotate on the surface of the tree trunk, which can avoid damaging the tree trunk.

[0052] By providing the fertilizer applicator 2, when the fertilizer applicator is used, the annular groove effect is improved and the difficulty of the annular groove is reduced;

[0053] When in use, the groove depth of the ring ditch fertilization of the bayberry tree needs to reach 30 centimeters. The groove depth is deep, and the conventional fertilization device cannot meet the 30-centimeter-deep ground-breaking operation in a single movement. By setting the fertilizer applicator 2, the ground-breaking cone 31 is moved downward by a certain distance through the lifting sleeve 27 every time the ground-breaking cone 31 moves in a ring. Each time it moves ten centimeters, the groove depth of the ground-breaking cone 31 is gradually increased. After multiple ring movements, the depth of the ground-breaking cone 31 is 30 centimeters, thereby reducing the difficulty of grooving the ground-breaking cone 31. The positioning groove 26 is used in conjunction with the clamping bolt structure to fix the lifting sleeve 27 after moving. In order to improve the use effect of the ground-breaking cone 31, the spring structure of the elastic clamp ring 30 is used to make the lifting sleeve 27 and the ground-breaking cone 31 elastically connected. When the ground-breaking cone 31 moves, the ground-breaking cone 31 can be in close contact with the soil to avoid gaps.

[0054] By providing the backfill plate 3 and the feed roller 14, when the fertilizing device is used, it can simultaneously complete the fertilizing and soil backfilling operations, thereby improving its working efficiency, quantitatively fertilizing according to the size of the annular groove, and improving its fertilizing effect;

[0055] During operation, the user fills the fertilizer box 6 with fertilizer, and connects the bar slot 12 through the docking card strip 13, so that the fertilizer box 6 is spliced ​​and installed on the upper end of the docking card seat 5, so that the discharge port of the fertilizer box 6 and the feed roller 14 are docked with each other. When the user pushes the fertilization device to move, the driving wheel 1 rotates, and the gear cooperates with the transmission chain 10 to make the driving wheel 1 drive the feed roller 14 to rotate. The rotation of the feed roller 14 is used to complete the top material discharge of the fertilizer, and the fertilizer is discharged into the fertilizer spreader 2 and discharged downward through the fertilizer spreader 2. During the fertilizer spreading process of the fertilizer spreader 2, the soil on both sides of the annular groove is pushed by the backfilling plate 3, so that the soil is backfilled into the annular groove to complete the backfilling operation. The V-shaped structure is set so that when the backfilling plate 3 contacts the soil, the soil gathers to the middle, thereby gathering the soil.
