Description

Technical Field

[0001] This utility model relates to the field of agricultural tools technology, specifically to a banana core removal and sprouting device. Background Technology

[0002] To reduce the water and nutrient consumption of the mother plant by banana suckers, banana production typically involves cutting off the suckers or removing useless suckers with a shovel. While these methods are convenient and simple, cutting off the suckers fails to effectively remove the growing point in one go, causing them to quickly regrow and requiring repeated cutting, resulting in wasted labor. Removing suckers with a shovel creates numerous wounds on the banana plant, making it susceptible to root damage and pathogen infection, leading to plant diseases and hindered nutrient absorption. In terms of survival, the practice of retaining secondary banana suckers as a management method for the next crop is already being promoted and applied. However, current equipment focuses on destroying suckers; no suitable production tools are currently available to force the rapid growth of secondary suckers.

[0003] Chinese Patent Publication No. CN216362683U discloses a banana sprout remover, including a sleeve, a motor, a lifting rod, a base, a plug, and a cutting disc. The sleeve has an upper guide plate and a lower guide plate inside, with a supporting spring between them. The base is located at the bottom of the sleeve, and the plug is located at the bottom of the lifting rod. The cutting disc is fitted onto the bottom surface of the lifting rod, and a placement groove is formed on the right side of the back surface of the cutting disc. The motor is located at the top of the lifting rod. The lifting rod passes sequentially through the upper guide plate, the supporting spring, and the lower guide plate, and the lifting rod is movably connected to the top plate of the sleeve, the base, the upper guide plate, and the lower guide plate. Insert rods are located on both sides of the bottom of the base. This patent involves cutting the sucker with a rotating cutting disc, moving the plug to the bud core, and then turning on the motor to rotate the plug, thus damaging the bud core. This patent only damages the bud core to a certain extent through mechanical processing, and there is still a possibility of residue at the growth point deep in the pseudostem. Furthermore, the bulb is easily damaged or infected by pathogens, and it does not involve inducing suckers to grow secondary buds. Summary of the Invention

[0004] The main purpose of this utility model is to overcome the defects of the above-mentioned background technology and provide a banana core removal and sprouting device.

[0005] To achieve the above objectives, this utility model proposes a banana core removal and sprouting device, comprising a conical drill bit, a connecting rod, and a handle. The conical drill bit is located at the bottom of the connecting rod, and the handle is located at the top of the connecting rod. The conical drill bit has a hollow conical cylindrical structure. A medicine storage bottle is provided on the connecting rod, and a press-type pump head is provided on the medicine storage bottle. A liquid dispensing handle is hinged to the handle, and one end of the liquid dispensing handle abuts against the press-type pump head. A plurality of medicine seepage holes are formed on the outer wall around the bottom of the conical drill bit. A liquid guiding channel is provided in the side wall of the conical drill bit, which is connected to the medicine seepage holes. One end of the press-type pump head is connected to the interior of the medicine storage bottle, and the other end of the press-type pump head is connected to the liquid guiding channel through a liquid delivery pipe.

[0006] To further optimize the technical solution, the bottom end of the tapered drill bit is designed with a beveled tip structure.

[0007] To further optimize the technical solution, the side wall of the conical drill bit is provided with an annular distribution channel, which is connected to the fluid guiding channel. The side wall of the conical drill bit is provided with several diversion channels evenly spaced around the annular distribution channel. One end of each diversion channel is connected to the annular distribution channel, and the other end of each diversion channel is connected to the corresponding drug seepage hole.

[0008] To further optimize the technical solution, the edges of the medicine seepage holes are all rounded and chamfered.

[0009] To further optimize the technical solution, a foot pedal is provided on the outer wall of the top of the conical drill bit.

[0010] To further optimize the technical solution, the press-type pump head includes a liquid storage cylinder, a first one-way valve, a pressing tube, and a piston. The bottom end of the liquid storage cylinder is connected to a suction tube, the bottom end of which extends into the interior of the medicine storage bottle. The first one-way valve is located at the opening at the top of the suction tube. The bottom of the pressing tube is movably inserted into the liquid storage cylinder. A spring is provided at the bottom end of the pressing tube. The piston is sleeved on the tube body of the pressing tube located inside the liquid storage cylinder. Several inlet holes communicating with the liquid storage cylinder are opened on the tube body of the pressing tube located below the piston. The outlet at the top of the pressing tube is connected to the infusion pipeline. One end of the dispensing handle abuts against the top end of the pressing tube.

[0011] To further optimize the technical solution, the first one-way valve includes a first check ball and a first funnel. The large end of the first funnel is connected to the bottom end of the liquid storage cylinder, and the small end of the first funnel is connected to the suction tube. The first check ball is movably disposed inside the first funnel, and the diameter of the first check ball is larger than the diameter of the small end of the first funnel.

[0012] To further optimize the technical solution, a first limiting mesh plate is provided at the large opening end of the first funnel, and the bottom end of the spring abuts against the edge of the first limiting mesh plate.

[0013] To further optimize the technical solution, a limiting block is provided on the outer periphery of the pressing tube, and the piston is movably sleeved between the limiting block and the liquid inlet hole.

[0014] To further optimize the technical solution, the inside of the pressing tube is provided with a second one-way valve. The second one-way valve includes a second check ball and a second funnel. The second check ball is movably disposed in the second funnel. The diameter of the second check ball is larger than the diameter of the small opening end of the second funnel. The large opening end of the second funnel is provided with a second limiting mesh plate.

[0015] The beneficial effects of this invention include: by holding the handle and aligning the bottom of the conical drill bit with the core of the banana sucker after it has been cut flat, and then pressing down to insert the conical drill bit perpendicular to the growth axis of the sucker, the core of the sucker is cut off and separated from the pseudostem and is dug out inside the conical drill bit. At the same time, while pulling the conical drill bit out upwards by holding the handle, the liquid dispensing handle is pulled upwards. The liquid dispensing handle is pressed down on the press pump head to pump the liquid in the liquid storage bottle to the liquid seepage hole, and the liquid flows from the liquid seepage hole to the center of the pseudostem after the core has been dug out. In one operation, the growth point of the banana sucker can be destroyed by a combination of chemical treatment and mechanical treatment, and the removal is more thorough. This can effectively improve the effect of banana sucker treatment, reduce the regeneration rate of banana suckers, reduce the ineffective consumption of nutrients, and promote the healthy growth of the banana plant and increase fruit yield. When it is necessary to promote the growth of secondary buds from suckers, replace the bud-removing agent in the solution storage bottle with a bud-promoting agent. This can accelerate the healing of wounds caused by removing the core, promote the uniform growth of secondary buds, and make it easier to select secondary buds with deep bud positions and uniform growth for later management.

[0025] Please see Figures 1 to 4In one embodiment, the banana core removal and sprouting device includes a conical drill bit 1, a connecting rod 2, and a handle 3. The conical drill bit 1 is located at the bottom of the connecting rod 2, and the handle 3 is horizontally located at the top of the connecting rod 2. The conical drill bit 1 has a hollow conical cylindrical structure. A medicine storage bottle 4 is fixedly mounted on the connecting rod 2. A press-type pump head 5 is mounted on the medicine storage bottle 4. A liquid dispensing handle 6 is hinged to the handle 3. One end of the liquid dispensing handle 6 abuts against the press-type pump head 5. A plurality of medicine seepage holes 101 are opened around the outer wall of the bottom of the conical drill bit 1. A liquid guiding channel 102 communicating with the medicine seepage holes 101 is provided in the side wall of the conical drill bit 1. The liquid suction end of the press-type pump head 5 is connected to the inside of the medicine storage bottle 4, and the liquid dispensing end of the press-type pump head 5 is connected to the liquid guiding channel 102 through a liquid delivery pipe 7. Specifically, the bottom end of the conical drill bit 1 is designed with a beveled tip structure 103. The sharp beveled tip facilitates penetration, helps the drill bit accurately align with the center of the banana pseudostem, and prevents slippage. A foot pedal 106 is provided on the outer wall of the top of the conical drill bit 1, allowing the operator to easily apply force by stepping on it, improving ease of use. Two connecting rods 2 are provided; the bottom ends of the two connecting rods 2 are welded and fixed to the two side walls of the top of the conical drill bit 1, and the top ends of the two connecting rods 2 are welded and fixed to the handle 3. Two crossbars are connected to the upper middle part of the two connecting rods 2, and the medicine storage bottle 4 is fixed to the crossbars. The dispensing handle 6 is hinged to... The handle 3 forms a lever structure in the middle, with the hinge point serving as the fulcrum. The short side of the lever rests against the top of the press-type pump head 5. Manually lifting or releasing the handle 3 (long side of the lever) causes the short side of the lever to press down or release the press-type pump head 5, which draws the chemical solution stored in the liquid storage bottle 4, such as diesel or kerosene, which can destroy the growth point of the banana bud core, into the press-type pump head 5 and squeezes it out. The solution then flows out along the infusion pipe 7, the liquid guiding channel 102, and the liquid seepage hole 101. Of course, the chemical solution can also be a bud-promoting agent, such as 600 times diluted kasugamycin + 4 mg / L 6-benzylaminopurine + 1 mg / L IAA auxin, which is used to remove the central core while protecting the bulb, preventing the bulb from rotting, and promoting the uniform growth of the suckers from the bulb, so as to facilitate the selection and fixation of buds later.In this embodiment, after the pseudostem of the banana sucker is cut horizontally 3-6 cm above the ground, a banana core removal and bud-promoting device is used to remove the core and destroy the growth point. When removing the core, the bottom end of the conical drill bit 1 is aligned with the cut bud core by holding the handle 3, and then the conical drill bit 1 is pressed down to insert perpendicularly to the growth axis of the sucker. The bud core is cut and separated from the pseudostem and is dug out inside the conical drill bit 1. When the conical drill bit 1 is pulled out upward by holding the handle 3, the liquid handle 6 is pulled out upward. The other end of the liquid handle 6 is pressed down to press the pump head 5 to pump the liquid in the liquid storage bottle 4 to the liquid seepage hole 101, and the liquid seepage hole 101 flows directly to the position of the sucker growth point deep in the center of the pseudostem after the core has been removed. In one operation, the organic combination of chemical treatment and mechanical removal can be achieved. The removal and destruction of the sucker growth point deep in the pseudostem is more thorough, which effectively improves the efficiency of banana sucker treatment, reduces the regeneration rate of banana suckers, reduces the ineffective consumption of nutrients, and promotes the healthy growth of the banana main plant and increased fruit yield.

[0026] In a preferred embodiment, an annular distribution channel 104 is provided inside the side wall of the conical drill bit 1. The annular distribution channel 104 is connected to the liquid guiding channel 102. Several diversion channels 105 are evenly spaced around the bottom of the annular distribution channel 104 inside the side wall of the conical drill bit 1. One end of each diversion channel 105 is connected to the annular distribution channel 104 above, and the other end of each diversion channel 105 is connected to a corresponding chemical seepage hole 101. The chemical solution enters the annular distribution channel 104 through the liquid guiding channel 102 for distribution, and then is evenly distributed into the corresponding chemical seepage holes 101 through the diversion channels 105. This avoids excessive or insufficient local dosage of the chemical solution, achieving uniform distribution and improving the effectiveness of chemical treatment during banana core removal.

[0027] In a preferred embodiment, the edges of the medicine seepage holes 101 are all rounded and chamfered. Specifically, the medicine seepage holes 101 are blind holes arranged horizontally around the bottom of the conical drill bit 1. The rounded chamfers make the medicine seepage holes 101 form a semi-circular groove, which allows the medicine to flow out more thoroughly. Moreover, the smooth edges of the holes can reduce the scraping or tearing of the internal tissue of the banana pseudostem during the insertion and withdrawal of the conical drill bit 1.

[0028] In a specific example, the push-button pump head 5 includes a reservoir 501, a first one-way valve 502, a push-button tube 503, and a piston 504. A suction tube 505 is connected to the bottom end of the reservoir 501, extending to the interior of the medicine storage bottle 4 to draw chemicals from it. The first one-way valve 502 is located at the top opening of the suction tube 505, allowing chemicals to enter the reservoir 501 only from the interior of the medicine storage bottle 4. Chemicals drawn from the reservoir 501 cannot return to the medicine storage bottle 4. The push-button tube 503 is movably inserted into the reservoir 501 at its bottom. Half of the pressing tube 503 is located outside the liquid storage cylinder 501, and the other half is located inside the liquid storage cylinder 501. A spring 506 is provided at the bottom end of the pressing tube 503. A piston 504 is sleeved on the tube body of the pressing tube 503 located inside the liquid storage cylinder 501 and is movably sealed to the inner wall of the liquid storage cylinder 501. Several inlet holes 507 connected to the liquid storage cylinder 501 are opened on the tube body of the pressing tube 503 located below the piston 504, so that the liquid medicine in the liquid storage cylinder 501 can enter the interior of the pressing tube 503 through the inlet holes 507. The outlet at the top of the pressing tube 503 is connected to the infusion pipe 7, and one end of the dispensing handle 6 abuts against the top end of the pressing tube 503. When the dispensing handle 6 is pulled up, the other end of the dispensing handle 6 converts into downward pressure on the pressing tube 503. The pressing tube 503 compresses the spring 506 and moves downward, driving the piston 504 to move downward and compress the volume of the lower cavity. The original chemical in the storage cylinder 501 is subjected to increased pressure, causing the original chemical to flow along the inlet hole 507, the inside of the pressing tube 503, and the infusion pipe 7 into the guiding channel 102, and finally flow out from the drug seepage hole 101 to realize drug administration. After the dispensing handle 6 is released, the spring 506 returns to its original position and drives the pressing tube 503 and the piston 504 to rise. The lower part of the storage cylinder 501 generates negative pressure to draw the chemical in the drug storage bottle 4 upward. The first one-way valve 502 opens, and the chemical enters the storage cylinder 501 along the suction tube 505, waiting for the next press to dispense the liquid.

[0029] In a specific example, the first one-way valve 502 includes a first check ball 508 and a first funnel portion 509. The larger end of the first funnel portion 509 is connected to the bottom end of the storage cylinder 501, and the smaller end of the first funnel portion 509 is connected to the suction pipe 505. The first check ball 508 is movably disposed within the first funnel portion 509, and the diameter of the first check ball 508 is larger than the diameter of the smaller end of the first funnel portion 509. The combination of the first check ball 508 and the first funnel portion 509 forms a ball-type one-way valve. Under gravity or reverse pressure, the first check ball 508 sits at the smaller end of the first funnel portion 509, effectively preventing backflow of the medicine and ensuring that the medicine can only enter the storage cylinder 501 from the medicine storage bottle 4. The conical structure of the first funnel portion 509 can act as a guide, helping the first check ball 508 to accurately fall back to the bottom end of the first funnel portion 509, thus improving the reliability and repeatability of the seal.

[0030] In a specific example, a first limiting mesh plate 510 is provided at the wide end of the first funnel portion 509, and the bottom end of the spring 506 abuts against the edge of the first limiting mesh plate 510. The first limiting mesh plate 510 restricts the first check ball 508 from running outside the first funnel portion 509, so that the first check ball 508 cannot seal in time when the pressing tube 503 is pressed.

[0031] In a specific example, a limiting block 511 protrudes from the outer peripheral wall of the pressing tube 503, and the piston 504 is movably sleeved between the limiting block 511 and the inlet hole 507. That is, the piston 504 can slide up and down on the pressing tube 503, and the diameter of the spring 506 installed at the bottom end of the pressing tube 503 is larger than the inner diameter of the piston 504, so that the piston 504 cannot be disengaged from the bottom end of the pressing tube 503; when the pressing tube 503 moves downward, the upper end face of the piston 504 is pressed against the limiting block 511 and moves downward together to compress the chemical liquid below the reservoir 501. At this time, the piston 504 is located above the inlet hole 507, and the chemical liquid below the reservoir 501 can be compressed into the interior of the pressing tube 503; when the pressing tube 503 is in contact with the spring 506, the piston 504 can move downward together with the limiting block 511 to compress the chemical liquid below the reservoir 501. When piston 504 moves upward, the friction between piston 504 and the inner wall of storage cylinder 501 is greater than the friction between piston 504 and the outer wall of pressing tube 503, so they remain relatively stationary for a while. When the position of the inlet hole 507 on pressing tube 503 moves to the point where the inner ring wall of piston 504 is blocked, it moves upward along with pressing tube 503, creating a negative pressure below storage cylinder 501 and drawing the chemical liquid inside the medicine storage bottle 4 upward. At the same time, because piston 50 blocks inlet hole 507, it realizes the function of a one-way valve, and the chemical liquid remaining in pressing tube 503 cannot return to storage cylinder 501.

[0032] In a preferred embodiment, a second one-way valve 512 is provided inside the pressing tube 503. The second one-way valve 512 includes a second check ball 513 and a second funnel portion 514. The second check ball 513 is movably disposed inside the second funnel portion 514. The diameter of the second check ball 513 is larger than the diameter of the small opening end of the second funnel portion 514. A second limiting mesh plate 515 is provided at the large opening end of the second funnel portion 514. By setting a second one-way valve 512, the chemical liquid in the pressing tube 503 is allowed to flow towards the outlet direction and cannot flow back into the storage tank 501. When the pressing tube 503 is pressed down, the chemical liquid pushes the second check ball 513 to move upward, opening the bottom end of the second funnel 514, and the chemical liquid can be squeezed into the infusion pipeline 7. When the pressing tube 503 rises, the second check ball 513 falls back to block the bottom of the second funnel 514, and the chemical liquid in the pressing tube 503 and the infusion pipeline 7 cannot flow back.
