Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a double-row adjustable pineapple planting machine. Background Technology

[0002] In most cases of pineapple cultivation, rotary tillage and ridging machinery are used to compact the soil into strip-shaped raised surfaces. This changes the micro-topography to create an optimized water, heat, and air environment for pineapple growth. During the planting process, healthy crown buds or offshoots are selected for seedling cultivation, and then the cultivated seedlings are transplanted to the ridges in the field using a planting machine.

[0003] According to the patent application published on the Internet (authorization announcement number: CN219893821U), "This utility model discloses an offset pineapple transplanter, belonging to the field of agricultural machinery technology. It includes a transplanter body, wheels on the surface of the transplanter body, a pull rod on one side of the transplanter body, a placement box on the upper surface of the transplanter body, a connecting pipe at the bottom of the placement box, a fixed cavity connected to the bottom of the connecting pipe, a motor inside the fixed cavity, and a first gear connected to one end of the motor. In this embodiment, when fruit farmers plant pineapples on hillsides, the motor is started. The motor drives a second gear to rotate through the first gear, and the second gear drives a fixed block to rotate through the connecting rod. According to work needs, when the fixed block offsets the drive assembly and rotary tiller blades to a suitable position, the motor is turned off. The drive assembly then drives the rotary tiller blades to perform offset operations on the hillside, facilitating pineapple planting on hillsides and meeting people's usage needs."

[0004] Regarding the above description, the applicant believes the following problems exist: The device, by attaching wheels to a tractor or pushing manually, propels the transplanter to the hillside where pineapple transplanting is needed. Pineapple seedlings are placed inside the placement box. As needed, the motor is started, driving the first gear to rotate, which in turn drives the second gear. The second gear, via a connecting rod, drives the positioning tube and fixing block to rotate. The fixing block causes the drive assembly and rotary tiller blades to shift to a suitable position. The motor is then turned off, and the drive assembly is activated, driving the rotary tiller blades to perform offset operations. The rotary tiller blades loosen the soil and dig holes on the hillside. After completing their work, the transplanter moves forward, pushing the rotating rod. The rotating rod rotates within the limiting groove, causing the turntable to rotate. The turntable moves the drive rod, which in turn moves the drive plate within the sliding groove. The drive plate pushes the limiting plate to the inside of the placement box, causing the pineapple seedlings inside the placement box to fall into the connecting tube. The positioning tube collects the pineapple seedlings inside the connecting tube. The bottom of the positioning tube is aligned with the direction of the rotary tiller blade. Pineapple seedlings are positioned through the positioning tube into the holes dug by the rotary tiller blade, thus completing the sowing of pineapple seedlings. However, the height of the rotary tiller blade in this device is fixed and cannot be dynamically adjusted according to differences in soil hardness (e.g., deep loosening is required for clay soil, and shallow tilling is required for sandy soil) or planting depth requirements (pineapple seedlings need to be inserted 5-6cm into the soil). This results in poor terrain adaptability of the device. In addition, the pineapple seedlings in this device rely on the limiting plate to push them open and fall naturally. Pineapple seedlings are not regular standardized parts and have problems such as size differences, leaf entanglement, and soil clump sticking together. This can easily lead to multiple seedlings falling at the same time or missed sowing due to seedling accumulation, resulting in low planting accuracy of the device. Furthermore, the planting of pineapple seedlings in this device relies on the natural fall of the pineapple seedlings. Pineapple planting has clear requirements for the planting depth (too deep and the heart will rot, too shallow and the lodging will occur). The original device has an uncontrollable natural fall height (different seedling weights and soil clump sizes will lead to differences in fall depth), resulting in uneven seedling planting depths and a low survival rate of pineapple seedlings. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a double-row adjustable pineapple planting machine with the function of accurately discharging pineapple seedlings through the feeding component, thereby improving the planting accuracy of the device; the function of adjusting the planting depth of pineapple seedlings through the planting component, thereby improving the survival rate of pineapple seedlings planted by the device; and the function of adjusting the height of the rotary tillage blades through the adjustable crushing component, thereby improving the terrain adaptability of the device.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] The pineapple ridge double-row adjustable planting machine includes a planting machine body, a mounting plate, and an adjustable crushing component. The two sides of the planting machine body are rotatably connected to moving wheels. A pull rod is fixedly connected to one side of the planting machine body. An adjustable crushing component is installed on the outside of the planting machine body. A mounting plate is fixedly connected to the top of the planting machine body. A stepper motor is fixedly connected to the top of the mounting plate. A connecting block is fixedly connected to the output end of the stepper motor. A placement cylinder is fixedly connected to the outside of the connecting block. A limit tube is fixedly connected to the bottom of the mounting plate. A planting component is installed at the bottom of the planting machine body.

[0008] In one optional embodiment, the planting assembly includes a hydraulic push rod 1, which is fixedly connected to the bottom of the planting machine body. A sliding tube is fixedly connected to the output end of the hydraulic push rod 1. A hydraulic push rod 2 is fixedly connected to the outside of the sliding tube. A connecting rod is fixedly connected to the output end of the hydraulic push rod 2. A planting duckbill is fixedly connected to one side of the connecting rod. Rotary shafts are fixedly connected to both sides of the sliding tube.

[0009] In one optional embodiment, a through hole is provided on the duckbill for planting, and the duckbill for planting is rotatably connected to the outside of the rotating shaft through the through hole.

[0010] In one optional embodiment, a second through hole is provided on the sliding tube, and the sliding tube is slidably connected to the outside of the limiting tube through the second through hole.

[0011] In one optional embodiment, the adjustable crushing component includes a first outer shell, which is slidably connected to one side of the planter body. A second outer shell is fixedly connected to the side of the planter body away from the first outer shell. A second stepper motor is fixedly connected to the inner side of the first outer shell. A rectangular lead screw is fixedly connected to the output end of the second stepper motor. A first sliding block is threaded onto the rectangular lead screw. A limit rod is fixedly connected to the inner side of the second outer shell. A second sliding block is slidably connected to the outside of the limit rod. A drive motor is fixedly connected to the inner side of the second sliding block. A second gear is fixedly connected to the output end of the drive motor. A first gear meshes with one side of the second gear. A rotary tiller blade is fixedly connected to one side of the first gear.

[0012] In one optional embodiment, a through hole three is provided on the sliding block one, and the rotary tillage blade is rotatably connected to the inside of the sliding block one through the through hole three.

[0013] In one alternative implementation, the rotary tiller blades rise when the second stepper motor rotates clockwise, and fall when the second stepper motor rotates counterclockwise.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The stepper motor is started by the control device to drive the rectangular lead screw to rotate. The rectangular lead screw drives the sliding block to rise and fall, thereby driving the rotary tiller blade to rise and fall. This allows the user to adjust the height of the rotary tiller blade according to the usage situation, thus improving the terrain adaptability of the device.

[0016] 2. The user places the pineapple seedling into the placement tube, and then starts the stepper motor through the control device to drive the placement tube to rotate. This causes the placement tube with the pineapple seedling to rotate onto the limiting tube, so that the pineapple seedling falls into the limiting tube. This avoids the situation where multiple seedlings fall at the same time or are missed due to the accumulation of pineapple seedlings, thus improving the planting accuracy of the device.

[0017] 3. The pineapple seedling falls into the planting nozzle. Then, the control device activates hydraulic push rod one to push the planting nozzle into the soil on the ridge. Subsequently, hydraulic push rod two retracts the connecting rod, thereby opening the planting nozzle. This causes the planting nozzle to push the soil on both sides to form a pit, and the pineapple seedling inside the planting nozzle falls into the pit. Then, hydraulic push rod one retracts, and the soil on both sides of the pit flows back. At the same time, the user can adjust the hydraulic valve of hydraulic push rod one to control the amount of hydraulic oil entering hydraulic push rod one, thereby changing the extension length of hydraulic push rod one. This allows the user to adjust the depth of the planting nozzle inserted into the soil according to the usage situation, which helps to improve the survival rate of the pineapple seedling.

[0028] Please see Figures 1-5This utility model provides an embodiment of a pineapple ridge double-row adjustable planting machine, including a planting machine body 1, a mounting plate 401, and an adjustable crushing component. Moving wheels 2 are rotatably connected to both sides of the planting machine body 1. A pull rod 3 is fixedly connected to one side of the planting machine body 1. An adjustable crushing component is provided on the outside of the planting machine body 1. The mounting plate 401 is fixedly connected to the top of the planting machine body 1. A stepper motor 403 is fixedly connected to the top of the mounting plate 401. A connecting block 404 is fixedly connected to the output end of the stepper motor 403. A placement cylinder 405 is fixedly connected to the outside of the connecting block 404. A limit tube 4 is fixedly connected to the bottom of the mounting plate 401. 02. A planting assembly is provided at the bottom of the planting machine body 1. The planting assembly includes a hydraulic push rod 406, which is fixedly connected to the bottom of the planting machine body 1. A sliding tube 407 is fixedly connected to the output end of the hydraulic push rod 406. A hydraulic push rod 410 is fixedly connected to the outside of the sliding tube 407. A connecting rod 409 is fixedly connected to the output end of the hydraulic push rod 410. A planting nozzle 408 is fixedly connected to one side of the connecting rod 409. A rotating shaft 411 is fixedly connected to both sides of the sliding tube 407. A control device is provided on the planting machine body 1. By mounting the pull rod 3 on the tractor, the device is moved to the ridge surface via the moving wheels 2 for planting. Pineapple seedlings are placed inside the machine body 1. A tractor drives the device to move across the ridge. The adjustable crushing component loosens the soil. The user then places the pineapple seedlings into the placement cylinder 405. The control device then activates stepper motor 403 to rotate the placement cylinder 405, causing it to rotate onto the limiting tube 402. This allows the pineapple seedlings to fall into the limiting tube 402, preventing multiple seedlings from falling simultaneously or missing any, thus improving the planting accuracy. The seedlings then fall into the planting nozzle 408. Finally, the control device activates hydraulic push rod 406 to push the planting nozzle... The duckbill 408 is inserted into the soil on the ridge. Then, the hydraulic push rod 410 is activated to retract the connecting rod 409, thereby opening the planting duckbill 408. This causes the planting duckbill 408 to push the soil on both sides to form a pit. Then, the pineapple seedling inside the planting duckbill 408 falls into the pit. Then, the hydraulic push rod 406 is retracted, and the soil on both sides of the pit flows back. At the same time, the user can adjust the hydraulic valve of the hydraulic push rod 406 to control the amount of hydraulic oil entering the hydraulic push rod 406, thereby changing the extension length of the hydraulic push rod 406. This allows the user to adjust the insertion depth of the planting duckbill 408 into the soil according to the usage situation, which helps to improve the survival rate of the pineapple seedlings.

[0029] In a preferred embodiment of this utility model, a through hole is provided on the planting duckbill 408. The planting duckbill 408 is rotatably connected to the outside of the rotating shaft 411 through the through hole, which facilitates the movement of the planting duckbill 408 by activating the hydraulic push rod 410 to extend and retract, thereby facilitating the control of the opening and closing of the planting duckbill 408.

[0030] In a preferred embodiment of this utility model, a through hole 2 is provided on the sliding tube 407. The sliding tube 407 is slidably connected to the outside of the limiting tube 402 through the through hole 2, which helps the limiting tube 402 to limit the sliding tube 407, thereby making the extension and retraction of the sliding tube 407 more stable.

[0031] Please see Figure 2 and Figure 5 In this embodiment, the adjustable crushing component includes a first outer shell 501, which is slidably connected to one side of the planting machine body 1. A second outer shell 502 is fixedly connected to the side of the planting machine body 1 away from the first outer shell 501. A second stepper motor 503 is fixedly connected to the inner side of the first outer shell 501. A rectangular lead screw 504 is fixedly connected to the output end of the second stepper motor 503. A first sliding block 505 is threaded onto the rectangular lead screw 504. A limit rod 511 is fixedly connected to the inner side of the second outer shell 502. A second sliding block 510 is slidably connected to the outer side of the limit rod 511. A drive motor 509 is fixedly connected to the inner side of the second sliding block 510. A second gear 508 is fixedly connected to the output end of the drive motor 509. One side of 08 is connected to gear 507, and a rotary tiller 506 is fixedly connected to one side of gear 507. The stepper motor 503 is started by the control device to drive the rectangular lead screw 504 to rotate. The rectangular lead screw 504 drives the sliding block 505 to rise and fall, thereby driving the rotary tiller 506 to rise and fall. This allows the user to adjust the height of the rotary tiller 506 according to the usage situation, thereby improving the terrain adaptability of the device. Subsequently, the drive motor 509 is started by the control device to drive gear 508 to rotate. Gear 508 drives gear 507 to rotate the rotary tiller 506, thereby breaking up the soil on the ridge surface and loosening the soil.

[0032] In a preferred embodiment of this utility model, a through hole is provided on the sliding block 505, and the rotary tiller 506 is rotatably connected to the inside of the sliding block 505 through the through hole, which facilitates the gear 507 to drive the rotary tiller 506 to rotate, thereby facilitating the rotary tiller 506 to break up the soil.

[0033] In a preferred embodiment of this utility model, when the second stepper motor 503 rotates clockwise, the rotary tiller 506 rises, and when the second stepper motor 503 rotates counterclockwise, the rotary tiller 506 falls, thereby allowing the user to adjust the height of the rotary tiller 506 by rotating the second stepper motor 503 in both directions.

[0034] During operation, the planting machine body 1 is equipped with a control device. By mounting the pull rod 3 on the tractor, the device is moved to the ridge surface via the moving wheels 2. Pineapple seedlings are placed inside the planting machine body 1. The tractor drives the device to move on the ridge surface. The control device starts the stepper motor 503, which drives the rectangular lead screw 504 to rotate. The rectangular lead screw 504 drives the sliding block 505 to rise and fall, thereby driving the rotary tiller 506 to rise and fall. This allows the user to adjust the height of the rotary tiller 506 according to the usage situation, thus improving the device's terrain adaptability. Subsequently, the control device starts the drive motor 509, which drives the gear 508 to rotate. The gear 508 drives the gear 507, which drives the rotary tiller 506 to rotate, thereby breaking up the soil on the ridge surface and loosening the soil. Then, the user puts the pineapple seedlings into the placement cylinder 405, and then the control device starts the stepper motor 403, which drives the placement cylinder 405 to rotate, thereby driving the rotary tiller 506 to rise and fall. The pineapple seedling placement cylinder 405 rotates onto the limiting tube 402, causing the pineapple seedling to fall into the limiting tube 402. This prevents multiple seedlings from falling simultaneously or being missed due to seedling accumulation, thus improving the planting accuracy of the device. The seedling then falls into the planting nozzle 408. The control device then activates hydraulic push rod 406 to push the planting nozzle 408 into the soil on the ridge. Hydraulic push rod 410 then retracts the connecting rod 409, opening the planting nozzle 408. This causes the planting nozzle 408 to push aside the soil on both sides, forming a pit. The pineapple seedling in the planting nozzle 408 then falls into the pit. Hydraulic push rod 406 then retracts, allowing the soil on both sides of the pit to flow back. The user can adjust the hydraulic valve of hydraulic push rod 406 to control the amount of hydraulic oil entering it, thereby changing the extension length of hydraulic push rod 406. This allows the user to adjust the insertion depth of the planting nozzle 408 according to usage, thus improving the survival rate of the pineapple seedlings.

[0035] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.

[0036] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
