Description

TECHNICAL FIELD

[0001] The present application relates to the field of eggplant planting technology, and in particular to a fertilizing device and method for eggplant planting. BACKGROUND

[0002] Eggplant, also known as dwarf melon, hanging vegetable, eggplant, etc., is a plant of the Solanaceae family in the Solanaceae order, with a height of up to 1 meter. The small branches are ovate to long ovate, the calyx is nearly bell-shaped, the corolla is radial, the ovary is round, the top is densely covered with star-shaped hair, and the shape and color of the fruit are diverse. The fruit can be used for food. The roots, stems and leaves are used as astringents and diuretics. The leaves can also be used as anesthetics. The seeds are used as anti-inflammatory drugs and stimulants, but can cause stomach weakness and constipation. Eating the fruit can relieve mushroom poisoning.

[0003] The growth of eggplant requires the most potassium, followed by nitrogen, and less phosphorus. Fertilization is also needed during the growth of eggplant planting.

[0023] A fertilization device and method for eggplant cultivation, applicable to a fertilization device for eggplant cultivation, comprising:

[0024] S1. Use the wheels to move the entire device to one side of the eggplant planting pit, and always keep the distance from the eggplant planting pit the same, so that the fertilizer sleeve is directly above the eggplant planting pit.

[0025] S2. Plant eggplant plants in the pits, with a distance of 35-45cm between adjacent groups of pits. The single-use fertilizer sleeve moves to the center of the pits of the two groups of eggplant plants, and the pit depth at the center is 10-20cm. Driven by the drive motor, the meshing sleeve moves downward along the outside of the support column, causing the fertilizer sleeve, which moves synchronously with the meshing sleeve, to move downward. The bottom of the hole-digging plate forms a sharp point and penetrates the soil 10-20cm downward. As the handle pole is driven, the multiple sets of hole-digging plates distributed in a ring will expand outward synchronously, thus digging a set of pits for filling with compound fertilizer.

[0026] S3. Fill each group of pits with an appropriate amount of compound fertilizer. The amount of fertilizer applied to each group of pits is calculated based on 10kg-20kg per mu of eggplant planting area. Calculate the number of eggplants planted per mu, a, and divide 10kg-20kg by the number a to obtain the amount of compound fertilizer b required to fill each group of pits.

[0027] S4. Pour the compound fertilizer in batches into the inside of the feeding hopper and let it flow into the inside of the fertilizer sleeve. In each set of pits, operate the rocker at the top of the drive rod to drive the drive rod to rotate, causing the discharge screw at the bottom of the drive rod to rotate. When the discharge screw rotates a part, a part of the compound fertilizer will fall to the bottom of the fertilizer sleeve. It is necessary to calculate the relationship between the number of rotations c and b of the drive rod. The drive rod needs to be rotated c times in each set of pits.

[0028] S5. After filling the pit with compound fertilizer, rotate the handle pole in the opposite direction and drive the fertilizer sleeve upward with the drive motor. At this time, the compound fertilizer in the pit will be exposed. Then cover the pit with the soil dug out from the side of the pit until the compound fertilizer in the pit is completely covered.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] This invention utilizes a supporting horizontal plate and adjustable wheels at the bottom of the plate to move along the ground, allowing the entire device to move along one side of the radially arranged eggplants. By injecting compound fertilizer into the feeding hopper, it provides longer operating time and reduces the load. After reaching the designated hole-digging position, the automatic longitudinal movement of the engaging sleeve, combined with the manual rotation of the inner rod and the handle upright, completes the hole-digging and quantitative compound fertilizer application. Compared to traditional planting methods, this method eliminates the need for bending over when facing a large workload, making the work easier, reducing physical burden, and allowing for more accurate compound fertilizer application and easier control of hole-digging depth, maximizing the effectiveness of the compound fertilizer.

[0031] The present invention can complete the installation of the fertilizer sleeve by inserting the crossbar and the vertical hole. The position of the fertilizer sleeve on the side of the support column can be adjusted according to the fertilization operation requirements, so that fertilization can be performed on both the left and right sides in the forward direction, thereby improving the applicability of the device.

[0032] This invention features a detachable design for the perforation plate and the movable mounting plate, allowing for easy replacement of perforation plates of different sizes as needed, thus further expanding its applicability. Attached Figure Description

[0044] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0045] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see Figures 1-10The system includes: a supporting bottom plate 1, a supporting column 2 fixed to the top of the supporting bottom plate 1 by a bracket, and a fertilizer sleeve 11 parallel to the supporting column 2 on one side. It also includes: a bracket for fixing the bottom of the supporting column 2 fixed to the surface of the supporting bottom plate 1; a cavity inside the supporting column 2 containing a transmission screw 4; a drive motor 3 for driving the transmission screw 4 to rotate on the surface of the supporting bottom plate 1; a meshing sleeve 5 externally fitted onto the transmission screw 4; and opposing insertion blocks 6 fixed to the outside of the meshing sleeve 5. A portion of the meshing sleeve 5 is meshed around the transmission screw 4, while the other portion extends outward through an opening on the surface of the supporting column 2 and fits around the outside of the supporting column 2. By driving the transmission screw 4 to rotate via the drive motor 3, the meshing sleeve 5 can move longitudinally along the surface of the supporting column 2, thereby adjusting the position of the insertion blocks 6. The reinforcing sleeve 10 is reinforced with bolts. A crossbar 7 is fixed to the outer wall of the reinforcing sleeve 10. A vertical insertion hole 8 is longitudinally formed on the surface of the insertion block 6. A vertical insertion rod 9 is inserted into the groove of the vertical insertion hole 8. The top of the vertical insertion rod 9 is fixed to the end face of the crossbar 7. To fix the position of the fertilizer sleeve 11, the fertilizer sleeve 11 is connected to the insertion block 6 via the crossbar 7. The reinforcing sleeve 10 is then reinforced to the fertilizer sleeve 11 with bolts. The insertion rod 9 at the front end of the insertion crossbar 7 is longitudinally inserted into the hole of the insertion vertical hole 8, so that the lower half of the insertion rod 9 is exposed. The exposed part adopts a threaded structure. Then, a nut is used to fit the end of the insertion rod 9 to fix the insertion rod 9, thereby completing the connection between the insertion crossbar 7 and the insertion block 6. This allows the fertilizer sleeve 11 to remain parallel to one side of the support column 2, and the height of the fertilizer sleeve 11 can be changed as the engagement sleeve 5 moves longitudinally.

[0048] The drive inner rod 19 is longitudinally inserted into the cylinder of the fertilizer sleeve 11. A discharge screw 20 is fixedly mounted on the lower half of the drive inner rod 19. A screw support kit 21 is sleeved on the outside of the drive inner rod 19 and fixed to the inner wall of the fertilizer sleeve 11. The fertilizer sleeve 11 can store compound fertilizer. A rocker arm is installed at the top of the drive inner rod 19. With the support of the screw support kit 21, the discharge screw 20 can be rotated by driving the rocker arm. This causes the compound fertilizer retained in the fertilizer sleeve 11 to be discharged downwards as the discharge screw 20 rotates. The amount of compound fertilizer discharged can be adjusted by the rotation amplitude of the drive inner rod 19. This method can be used to discharge compound fertilizer into a single pit. The accurate amount of compound fertilizer dispensed can reduce dispensing errors. The fertilizer sleeve 11 is fitted with a leak-proof sleeve 39. The top of the leak-proof sleeve 39 is fixed with a feeding bin 18. The feeding bin 18 has a funnel-shaped structure and a large opening at the top, which can store a certain amount of compound fertilizer inside the feeding bin 18. The compound fertilizer can flow along the inner wall of the feeding bin 18 into the bucket of the fertilizer sleeve 11. The leak-proof sleeve 39 is reinforced to the outside of the support column 2 through a bracket, which can reduce the load on the fertilizer sleeve 11. The leak-proof sleeve 39 is fitted on the outside of the fertilizer sleeve 11 and slides with the fertilizer sleeve 11, so that the fertilizer sleeve 11 will not leak when it moves longitudinally.

[0049] A threaded guide groove 22 is located on the outside of the fertilizer sleeve 11, and a helical pressing column 23 is fitted around the outside of the threaded guide groove 22. A pressing moving column 24 is installed below the helical pressing column 23, and the helical pressing column 23 and the pressing moving column 24 are connected by a pressing connecting rod 25. An outwardly extending handle rod 28 is fixed to the outside of the helical pressing column 23. Since the helical pressing column 23 is fitted and engaged with the threaded guide groove 22, by driving the helical pressing column 23 to rotate, the helical pressing column 23 can move longitudinally outside the fertilizer sleeve 11, thereby allowing the pressing connecting rod 25 connected to the helical pressing column 23 to push the pressing moving column 24 to move longitudinally. In order to facilitate the operation of the helical pressing column 23, an L-shaped handle rod 28 is fixed to the outside of the helical pressing column 23. The handle 28 extends upward to facilitate the rotation of the spiral pressing column 23 without bending over. The top of the pressing moving column 24 is provided with a connecting rod guide groove 26. The bottom of the pressing connecting rod 25 is fixed with a bent part that extends into the groove of the connecting rod guide groove 26. The surface of the fertilizer sleeve 11 is longitudinally provided with a limiting longitudinal sliding groove 27. The inner wall of the pressing moving column 24 is fixed with a slider that slides into the groove of the limiting longitudinal sliding groove 27. Through the constraint of the limiting longitudinal sliding groove 27 and the slider in the limiting longitudinal sliding groove 27, the pressing moving column 24 can only move longitudinally along the surface of the fertilizer sleeve 11. Through the connection of the pressing connecting rod 25, the longitudinal movement of the spiral pressing column 23 can be transmitted to the pressing moving column 24. The bent part at the bottom of the pressing connecting rod 25 can pull the connecting rod guide groove 26 to move the pressing moving column 24 upward.

[0050] One end of the actuating linkage 29 is connected to the surface of the downward moving column 24, and the other end is connected to the actuating auxiliary rod 30. The actuating plate 31 is fixed to the end of the actuating auxiliary rod 30 away from the actuating linkage 29. A guide rotating shaft 32 is provided at the connection between the actuating plate 31 and the fertilizer sleeve 11. The hole-digging plate 33 is located at the lower part of the screw support assembly 21. The lower end of the hole-digging plate 33 is offset towards the center of the fertilizer sleeve 11. Utilizing the rotational capacity of the guide rotating shaft 32, the actuating plate 31 can rotate freely, creating circularly distributed holes. When the bottom of the plate 33 is descending, it is in a close-to-closed state, and the digging action is performed by unfolding the digging plate 33. When digging is needed, it is in a state of separation. By moving the plate 40 up and down, the drive motor 3 will rotate at an angle using the guide rotating shaft 32, thereby changing the angle of the plate 31 and thus changing the angle of the digging plate 33. The outer wall of the digging plate 33 is fixed with a digging guide plate 34. The sharp design of the digging guide plate 34 can reduce soil resistance and save physical strength during the digging process.

[0051] Two sets of adjustable horizontal plates 14 are installed on one side of the supporting base horizontal plate 1. The front ends of the two sets of adjustable horizontal plates 14 are inserted into the interior of the supporting base horizontal plate 1 via longitudinal rods. Several sets of horizontal plate slots 15 are opened at intervals on the surfaces of the two sets of adjustable horizontal plates 14. A horizontal bar locking rod 16 is inserted into the slot of the horizontal plate slot 15. The bottom of the adjustable horizontal plates 14 and the supporting base horizontal plate 1 is equipped with traveling wheels 17. The entire device can be moved using three sets of traveling wheels 17. Both sets of adjustable horizontal plates 14 are rotated with the supporting base horizontal plate 1 via longitudinal rods. When properly adjusted, the two sets of adjustable horizontal plates 14 can be unfolded. Then, the U-shaped horizontal bar locking rod 16 is inserted into the horizontal plate slot 15 closest to the supporting base horizontal plate 1, thereby achieving the maximum unfolding angle of the two sets of adjustable horizontal plates 14, improving the stability of the supporting base horizontal plate 1 during movement. In narrow places, the two sets of adjustable horizontal plates 14 can be brought as close as possible to facilitate the passage of the entire device. The top of the support column 2 is provided with a gripping crossbar 12, and a crossbar slot 13 is installed above the support column 2. One end of the crossbar slot 13 is fixed with a block that can be inserted into the groove of the gripping crossbar 12. The crossbar slot 13 and the support column 2 are detachable and can be moved along with the fertilizer sleeve 11 to facilitate the operation of the entire equipment.

[0052] The surface of the actuating plate 31 has a disassembly groove 35, and an assembly plate 36 is inserted into the disassembly groove 35. The center of the assembly plate 36 has an assembly screw hole 37. The surface of the screw support kit 21 has a mating screw hole 38 that matches the assembly screw hole 37. The assembly plate 36 can be inserted into the disassembly groove 35, and the assembly screw hole 37 can be aligned with the mating screw hole 38. Then, the assembly screw hole 37 and the mating screw hole 38 are connected by bolts, thereby completing the connection between the actuating plate 31 and the assembly plate 36. The assembly plate 36 is fixedly connected to a set of slotted plates 33. By inserting and disassembling the assembly plate 36 and the disassembly groove 35, slotted plates 33 of different sizes can be replaced.

[0053] A fertilization device and method for eggplant cultivation, applicable to a fertilization device for eggplant cultivation, comprising:

[0054] S1. Use the walking wheels 17 to move the entire device to one side of the eggplant planting pit, and always keep the distance from the eggplant planting pit the same, so that the fertilizer sleeve 11 is located directly above the eggplant planting pit.

[0055] S2. Plant eggplant plants in the pits, and make the distance between two adjacent groups of pits 35-45cm. The single fertilization sleeve 11 moves to the center of the pits of the two groups of eggplant plants, and the pit depth at the center is 10-20cm. Driven by the drive motor 3, the meshing sleeve 5 moves downward along the outside of the support column 2, so that the fertilization sleeve 11, which moves synchronously with the meshing sleeve 5, moves downward. The bottom of the hole-digging plate 33 forms a sharp part and penetrates the soil 10-20cm downward. With the drive of the handle column 28, the multiple groups of hole-digging plates 33 distributed in a ring will expand outward synchronously, thereby digging a set of pits for filling compound fertilizer.

[0056] S3. Fill each group of pits with an appropriate amount of compound fertilizer. The amount of fertilizer applied to each group of pits is calculated based on 10kg-20kg per mu of eggplant planting area. Calculate the number of eggplants planted per mu, a, and divide 10kg-20kg by the number a to obtain the amount of compound fertilizer b required to fill each group of pits.

[0057] S4. Pour the compound fertilizer in batches into the inside of the feeding hopper 18 and let the compound fertilizer flow into the inside of the fertilizer sleeve 11. In each set of pits, operate the rocker at the top of the driving inner rod 19 to drive the driving inner rod 19 to rotate, so that the discharge screw 20 at the bottom of the driving inner rod 19 rotates. When the discharge screw 20 rotates a part, a part of the compound fertilizer will fall at the bottom of the fertilizer sleeve 11. It is necessary to calculate the relationship between the number of rotations c and b of the driving inner rod 19. The driving inner rod 19 needs to be rotated c times in each set of pits.

[0058] S5. After filling the pit with compound fertilizer, rotate the handle pole 28 in the direction of rotation and drive the drive motor 3 to lift the fertilizer sleeve 11 upward. At this time, the compound fertilizer is exposed in the pit. Then cover the pit with the soil dug out from the side of the pit until the compound fertilizer in the pit is completely covered.

A grooving guide plate (34) is fixed on the outer wall of the grooving plate (33).

9. A method for using a fertilization device for eggplant cultivation, characterized in that, The device includes a fertilization apparatus for eggplant cultivation as described in claim 8 above, comprising: S1. Use the walking wheels (17) to move the entire device to one side of the eggplant planting pit, and always keep the distance from the eggplant planting pit the same, so that the fertilizer sleeve (11) is located directly above the eggplant planting pit. S2. Plant eggplant plants in the pits and make the distance between two adjacent pits between 35-45cm. The single fertilization sleeve (11) moves to the center of the pits of the two eggplant plants and the pit depth at the center is 10-20cm. Driven by the drive motor (3), the meshing sleeve (5) moves downward along the outside of the support column (2), so that the fertilization sleeve (11) moves downward synchronously with the meshing sleeve (5). The bottom of the hole-digging plate (33) forms a sharp part and penetrates the soil 10-20cm downward. With the drive of the handle rod (28), the multiple hole-digging plates (33) distributed in a ring will expand outward synchronously, so as to dig out a set of pits for filling compound fertilizer. S3. Fill each group of pits with an appropriate amount of compound fertilizer. The amount of fertilizer applied to each group of pits is calculated based on 10kg-20kg per mu of eggplant planting area. Calculate the number of eggplants planted per mu, a, and divide 10kg-20kg by the number a to obtain the amount of compound fertilizer b required to fill each group of pits. S4. Pour the compound fertilizer into the inside of the feeding bin (18) in batches and let the compound fertilizer flow into the inside of the fertilizer sleeve (11). In each set of pits, operate the rocker at the top of the driving inner rod (19) to drive the driving inner rod (19) to rotate, so that the discharge screw (20) at the bottom of the driving inner rod (19) rotates. When the discharge screw (20) rotates a part, a part of the compound fertilizer will fall at the bottom of the fertilizer sleeve (11). It is necessary to calculate the relationship between the number of rotations c and b of the driving inner rod (19). The driving inner rod (19) needs to be rotated c times in each set of pits. S5. After filling the pit with compound fertilizer, rotate the handle pole (28) in the direction and drive the drive motor (3) to drive the fertilizer sleeve (11) to lift upward. At this time, the compound fertilizer is exposed in the pit. Then cover the pit with the soil dug out next to the pit until the compound fertilizer in the pit is completely covered.
