Abstract

The invention relates to the technical field of fertilizing devices and discloses a fertilizing device for banana seedlings. The fertilizing device comprises a base, a bracket fixedly mounted on the upper surface of the base, a liquid storage tank fixedly mounted on the top of the bracket, and two pump casings symmetrically fixedly mounted on the outer surfaces of opposite sides of the bracket. The device drives a semicircular block to rotate through the movement of a shift lever, and the semicircular block drives a semicircular ring protrusion to rotate. The semicircular ring protrusion lifts an L-shaped rod, and the L-shaped rod drives a sliding column to move upward. The upward movement of the sliding column allows a channel to connect two water pipe joints. Liquid fertilizer in the liquid storage tank enters the interior of a water spray pipe through a delivery pipe and a connecting pipe, and is then sprayed out from a nozzle. With the device, fertilization can be achieved when the liquid fertilizer contacts the banana seedlings, avoiding fertilization at an idle position of the banana seedlings, thereby greatly reducing fertilizer waste during fertilization.

The movement of the gear lever 20 drives the semicircular block 36 to rotate, and the semicircular block 36 drives the semicircular ring protrusion 28 to rotate, and the L-shaped rod 25 is lifted up by the semicircular ring protrusion 28. The L-shaped rod 25 drives the sliding column 22 to move upward, and the upward movement of the sliding column 22 causes the channel 2201 to connect the two water pipe joints 23. The liquid fertilizer inside the liquid storage tank 4 enters the interior of the water spray pipe 34 through the delivery pipe 13 and the connecting pipe 24, and then is sprayed out from the nozzle. Through this device, fertilization can be achieved when the banana seedling plant is in contact, avoiding fertilization in the idle position of the banana seedling plant, which greatly reduces the waste of fertilizer during fertilization.

[0034] The outer surface of the clamping strip 39 is evenly provided with a plurality of latch teeth, and a toggle ring 40 is fixedly installed on the outer surface of the clamping strip 39 near the top of the water spray pipe 34. The outer surface of the clamping strip 39 is evenly provided with a plurality of latch teeth, and a toggle ring 40 is fixedly installed on the outer surface of the toggle ring 40. The outer surface of the toggle ring 40 is fixedly installed on the outer surface of the toggle ring 40. The toggle protrusion 41 is abutted against the outer surface of the latch teeth. The outer surface of the water spray pipe 34 near the bottom end is provided with a torsion spring 35. The end surface of the T-shaped block 31 away from the end of the rotating box 18 is fixedly installed with a limiting post 32.

One end of the second spring 33 is fixedly connected to the outer surface of the T-shaped block 31, and the other end of the second spring 33 is fixedly connected to the inner wall of one end of the T-shaped slot 29.

[0035] Through the relative displacement of the gear lever 20 and the banana seedling plant, the anti-slip strip 30 can slide along the T-shaped groove 29 when in contact with the banana seedling plant. The anti-slip strip 30 drives the clamping strip 39 to move through the T-shaped block 31. The clamping strip 39 intermittently abuts against the toggle protrusion 41 through the clamping teeth on the surface, so that the toggle ring 40 swings back and forth under the action of the torsion spring 35. Through this device, the toggle ring 40 drives the nozzle to swing back and forth at a certain angle, so that the liquid fertilizer sprayed from the nozzle can be sprayed evenly. At the same time, when the gear lever 20 leaves the banana seedling plant, the liquid fertilizer inside the water spray pipe 34 can be thrown out through the swing of the nozzle to prevent the liquid fertilizer from drying and clogging the nozzle.

The clamping knob 16 is threadedly connected to the rotating arm 15.

[0037] The user turns the angle of the rotating arm 15 according to the spacing between the two rows of banana seedlings so that the rotating arms 15 on both sides are at the same distance from the two rows of banana seedlings, and the anti-slip strip 30 on the gear lever 20 can contact the outer surface of the banana seedling. After adjusting the angle, the user manually tightens the clamping knob 16 so that the clamping knob 16 can fix the angle of the rotating arm 15. The distance between the gear lever 20 and the banana seedling can be adjusted by the device, and banana seedlings with different spacings can be fertilized, thereby increasing the applicability of the device.

[0038] In this embodiment, two rotating shafts 3 are symmetrically mounted between the inner walls on opposite sides of the base 1, and rollers 2 are fixedly mounted at both ends of the two rotating shafts 3. Two sprockets 7 are symmetrically fixedly mounted on the outer surface of one of the rotating shafts 3. A transmission shaft 6 is rotatably mounted between the inner walls of the bracket. Two identical sprockets 7 are symmetrically fixedly mounted on the outer surface of the transmission shaft 6. A chain 8 is sleeved on the circumferential outer surface of the two sprockets 7 on the adjacent side. Two bevel gears 9 are symmetrically fixedly mounted on the circumferential outer surface of the transmission shaft 6 near both ends. The lower surfaces of the two pump casings 10 are The same bevel gear 9 is rotatably installed, and two adjacent bevel gears 9 are meshed with each other. The bottom walls of the two pump casings 10 are rotatably installed with pump fans 12. The bottom end of the rotation center of the pump fan 12 passes through the lower surface of the pump casing 10 and is fixedly installed with the rotation center of one of the bevel gears 9. Two pipes 11 are symmetrically fixedly installed on the lower surface of the liquid storage tank 4.

The outer surface of the top of the bracket near one end of the L-shaped rod 25 is fixedly installed with an armrest 5.

[0039] By manually pushing the handrail 5, the device is moved between the two rows of banana seedlings through the roller 2, which is convenient for continuous fertilization of the banana seedlings. The roller 2 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives one of the bevel gears 9 to rotate through the sprocket 7 and the chain 8. The bevel gear 9 drives the pump fan 12 to rotate through the other bevel gear 9. The pump fan 12 will suck the liquid fertilizer inside the liquid storage tank 4 to facilitate subsequent fertilization.

[0040] It should be noted that when the present invention is used, the user first adds a quantitative amount of the mixed liquid fertilizer into the liquid storage tank 4 for storage, so as to facilitate subsequent fertilization;

[0041] Then, the user turns the angle of the rotating arm 15 according to the spacing between the two rows of banana seedlings, so that the rotating arms 15 on both sides are at the same distance from the two rows of banana seedlings, and the anti-slip strip 30 on the gear lever 20 can contact the outer surface of the banana seedling. After adjusting the angle, the user manually tightens the pressing knob 16 so that the pressing knob 16 can fix the angle of the rotating arm 15. The distance between the gear lever 20 and the banana seedling can be adjusted by the device, and banana seedlings with different spacings can be fertilized, thereby increasing the applicability of the device.

[0042] When the rotating arm 15 is pulled, the rotating box 18 is driven to rotate through the connecting rod 17 and the fixed rod 19. The rotating box 18 drives the gear lever 20 to move through the two circular arc springs 37 and the semicircular block 36, so that when the rotating arm 15 is adjusted, the gear lever 20 can always remain perpendicular to the banana seedling plant, which is convenient for subsequent fertilization.

[0043] By manually pushing the handrail 5, the device is moved between the two rows of banana seedlings via the roller 2, which facilitates continuous fertilization of the banana seedlings. The roller 2 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives one of the bevel gears 9 to rotate through the sprocket 7 and the chain 8. The bevel gear 9 drives the pump fan 12 to rotate through the other bevel gear 9. The pump fan 12 will suck the liquid fertilizer inside the liquid storage tank 4 to facilitate subsequent fertilization.

[0044] When the gear lever 20 moves to the banana seedling position of the adjacent plant, the outer surface of the anti-slip strip 30 will contact the surface of the banana seedling plant. At this time, when the pushing device continues to move, the gear lever 20 will swing in the opposite direction of the movement by a certain angle, and the semicircular block 36 is driven to rotate by the movement of the gear lever 20, and the semicircular block 36 drives the semicircular ring protrusion 28 to rotate, and the L-shaped rod 25 is lifted up by the semicircular ring protrusion 28. The L-shaped rod 25 drives the sliding column 22 to move upward, and the upward movement of the sliding column 22 causes the channel 2201 to connect the two water pipe joints 23. The liquid fertilizer inside the liquid storage tank 4 enters the interior of the water spray pipe 34 through the delivery pipe 13 and the connecting pipe 24, and then is sprayed out from the nozzle. Through this device, fertilization can be achieved when the banana seedling plant is in contact, avoiding fertilization in the idle position of the banana seedling plant, which greatly reduces the waste of fertilizer during fertilization;

[0045] Through the relative displacement of the gear lever 20 and the banana seedling plant, the anti-slip strip 30 can slide along the T-shaped groove 29 when in contact with the banana seedling plant. The anti-slip strip 30 drives the clamping strip 39 to move through the T-shaped block 31. The clamping strip 39 intermittently abuts against the toggle protrusion 41 through the clamping teeth on the surface, so that the toggle ring 40 swings back and forth under the action of the torsion spring 35. Through this device, the toggle ring 40 drives the nozzle to swing back and forth at a certain angle, so that the liquid fertilizer sprayed from the nozzle can be sprayed evenly. At the same time, when the gear lever 20 leaves the banana seedling plant, the liquid fertilizer inside the water spray pipe 34 can be thrown out through the swing of the nozzle to prevent the liquid fertilizer from drying and clogging the nozzle.
