Description

Technical Field

[0001] This utility model relates to the field of planting device technology, specifically a ridge-planting double-row pineapple mulch positioning planting device. Background Technology

[0002] In the context of the rapid development and continuous innovation of modern agricultural technology, various new types of planting equipment have emerged like mushrooms after rain. Among them, the mulching positioning planter has become an extremely important piece of equipment in the planting field due to its unique design and advanced functions. The device creates a good environment for the growth of plants and plays an irreplaceable key role.

[0003] In existing technologies, the traditional single-size duckbill has limitations when dealing with pineapple seedlings of different varieties and growth stages in practical applications. To solve this problem, some growers have tried to replace the duckbill with different sizes, but this process is extremely complicated. The traditional bolt fixing method is very time-consuming when the duckbill needs to be replaced frequently, which also increases the workload of the staff. Moreover, when the planter moves, it inevitably shakes. If the duckbill is not installed and connected stably, it is easy to loosen or fall off. Once the duckbill loosens or falls off, it will not only affect the normal progress of planting work, but also lead to a significant decrease in planting efficiency, and further affect the planting quality and yield of pineapples. Utility Model Content

[0004] The purpose of this utility model is to provide a pineapple mulching positioning planter for ridge planting in double rows, in order to solve the problems mentioned in the background art, such as the difficulty of adapting a single duckbill to different varieties of seedlings, the inconvenience of traditional installation methods when replacement is required, and the shaking caused by the movement of the planter after installation, which can easily cause the duckbill connection to become unstable, resulting in the duckbill loosening and falling off, thus affecting planting efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-row pineapple mulching and positioning planter, comprising a main body, a support wheel rotatably connected to the main body, a suspension bracket fixedly installed on the main body, a guide sleeve slidably connected to the main body, a drive assembly on the main body, a rotating rod rotatably connected to the guide sleeve, a spring assembly between the guide sleeve and the rotating rod, an adjustment assembly on the rotating rod, a snap-fit ​​assembly on the rotating rod, a limiting assembly on the rotating rod, a duckbill plate on the rotating rod, a pressing rod fixedly installed on the main body, and a mulching assembly on the main body. The drive assembly is used to adjust the movement of the guide sleeve. When the guide sleeve moves, the pressing rod presses the rotating rod, driving the rotating rod and opening the duckbill plate. When the guide sleeve resets, the spring assembly pushes the rotating rod back to its original position. The adjustment assembly is used to adjust the movement of the snap-fit ​​assembly and to restrict the installation of the duckbill plate. The limiting assembly is used to restrict the adjustment assembly after the duckbill plate is installed.

[0006] According to the preferred embodiment of this technical solution, the spring assembly includes a first rotating seat rotatably connected to the guide sleeve, a second rotating seat rotatably connected to the rotating rod, and a first spring fixedly connected between the first rotating seat and the second rotating seat.

[0007] According to the preferred embodiment of this technical solution, the adjustment component includes a push button slidably connected to the rotating rod, a connecting plate fixedly connected to the bottom of the push button, a second spring fixedly connected between the connecting plate and the rotating rod, and a sliding block slidably connected inside the rotating rod. The connecting plate is slidably connected to the sliding block. By pressing the push button, the connecting plate is moved, and when the connecting plate moves, it drives the sliding blocks on both sides to move.

[0008] In a preferred embodiment of this technical solution, the sliding block has a groove adapted to the connecting plate, and the connecting plate is slidably connected to the groove.

[0009] In a preferred embodiment of this technical solution, the snap-fit ​​assembly includes a snap-fit ​​block fixedly installed at one end of the sliding block, a third spring fixedly connected between the snap-fit ​​block and the rotating rod, an mounting rod fixedly installed on the duckbill plate, the mounting rod being mounted on the rotating rod, the snap-fit ​​block being snap-fitted onto the mounting rod, and the snap-fit ​​block moving together with the sliding block when the sliding block moves.

[0010] In a preferred embodiment of this technical solution, the limiting component includes a fixed seat fixedly mounted on a rotating rod, an adjusting screw rotatably connected to the fixed seat, a sliding bracket threadedly connected to the adjusting screw, and a limiting block fixedly mounted on the sliding bracket. The sliding bracket is slidably connected to the fixed seat, and the limiting block is slidably connected to the push button. The adjusting screw is used to adjust the movement of the sliding bracket, and the sliding bracket moves to drive the limiting block to move.

[0011] According to the preferred embodiment of this technical solution, the driving component includes a first motor fixedly installed on the main body of the device, a rotating disk fixedly connected to the output end of the first motor, a linkage rod fixedly connected to the rotating disk, a fixed bracket fixedly connected to the guide sleeve, and a linkage block fixedly connected to the fixed bracket. The linkage rod is slidably connected to the linkage block. The first motor is used to drive the rotating disk to rotate. When the rotating disk rotates, it drives the fixed bracket and the guide sleeve to reciprocate through the linkage rod and the linkage block.

[0012] Based on the preferred embodiment of this technical solution, the film coating assembly includes a film coating roller rotatably connected to the main body of the device, a pressure roller rotatably connected to the main body of the device, a sliding support rod slidably connected to the main body of the device, a first pressing knob threadedly connected to the sliding support rod, a second pressing knob threadedly connected to the sliding support rod, a connecting rod movably connected to the sliding support rod, and a pusher fixedly installed at the bottom of the connecting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When it is necessary to disassemble and replace the duckbill plate, the locking component can be driven by the adjustment component to quickly release the limit on the duckbill plate. Then, the old duckbill plate can be directly removed, and the new duckbill plate can be replaced. The operation can be reversed to complete the fixation. This shortens the time required for disassembly and installation, greatly increases the convenience of installation and disassembly, and indirectly improves the quality and yield of pineapple planting.

[0015] 2. By setting a limit component, the button is connected to the limit block during use to restrict the movement of the button, thereby ensuring that the button remains in place when shaking or vibrating, and preventing the connected transmission component from opening the locking component due to shaking or accidental contact, which would cause the duckbill plate to fall off.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 6This utility model provides an embodiment of a double-row pineapple mulching positioning planter, comprising a main body 1, a support wheel 4 rotatably connected to the main body 1, a suspension bracket 5 fixedly installed on the main body 1, a guide sleeve 21 slidably connected to the main body 1, a drive assembly disposed on the main body 1, a rotating rod 22 rotatably connected to the guide sleeve 21, a spring assembly disposed between the guide sleeve 21 and the rotating rod 22, an adjustment assembly disposed on the rotating rod 22, a snap-fit ​​assembly disposed on the rotating rod 22, a limiting assembly disposed on the rotating rod 22, and a duckbill plate 2 disposed on the rotating rod 22. 3. A pressing rod 24 is fixedly installed on the main body 1 of the device. A film-coating assembly is set on the main body 1 of the device. A drive assembly is used to adjust the movement of the guide sleeve 21. When the guide sleeve 21 moves, it presses the rotating rod 22 through the pressing rod 24, which drives the rotating rod 22 to open the duckbill plate 23. When the guide sleeve 21 is reset, the rotating rod 22 is pushed back to its original position by the spring assembly. An adjustment assembly is used to adjust the movement of the snap-fit ​​assembly and to restrict the installation of the duckbill plate 23 through the snap-fit ​​assembly. A limiting assembly is used to restrict the adjustment assembly after the duckbill plate 23 is installed. This embodiment needs to be used in conjunction with agricultural machinery equipment, usually using self-propelled tracks or tires. The device is moved by mounting the suspension bracket 5 onto the carrier. When the main body 1 moves, the covering component first works to cover the soil layer to be planted with a protective film. After the worker puts the seedling into the guide sleeve 21, the seedling falls to the bottom of the guide sleeve 21. At this time, the duckbill plate 23 closes, restricting the seedling. Subsequently, the drive component works to control the reciprocating movement of the guide sleeve 21. When the guide sleeve 21 moves, it drives the rotating rod 22 and other components to move. During the process of the guide sleeve 21 and the rotating rod 22 moving to the bottom of the stroke, the duckbill plate 23 first passes through the film and inserts into the soil. The rotating rod 22 is squeezed by the squeezing rod 24, causing it to rotate on the guide sleeve 21, thereby opening the duckbill plate 23. While pushing away the soil, the seedling falls into the pit. After the guide sleeve 21 rises, the spring assembly pushes the rotating rod 22, causing it to return to its original position after moving away from the squeezing rod 24. This process is repeated to perform the planting action. When the duckbill plate 23 needs to be replaced, the limiting assembly is first adjusted to release the restriction on the adjusting assembly. Then, the adjusting assembly is manipulated to move the locking assembly, thereby releasing the restriction on the duckbill plate 23. The duckbill plate 23 can then be removed for replacement.

[0025] Please see Figure 4A further solution based on this embodiment is as follows: The spring assembly includes a first rotating seat 25 rotatably connected to the guide sleeve 21, a second rotating seat 26 rotatably connected to the rotating rod 22, and a first spring 27 fixedly connected between the first rotating seat 25 and the second rotating seat 26. Through the rotatable connection between the first rotating seat 25 and the guide sleeve 21, and the second rotating seat 26 and the rotating rod 22, combined with the elastic effect of the first spring 27, the rotating rod 22 can rotate flexibly relative to the guide sleeve 21. At the same time, the first spring 27 can provide a buffer force for the rotation process. When the guide sleeve 21 moves downward, the rotating rod 22 is pushed by the squeezing rod 24, which drives the duckbill plate 23 to open, pushing the soil outward and causing the seedlings inside the guide sleeve 21 to fall into the soil. When the guide sleeve 21 rises later, it can drive the rotating rod 22 to return to its original position, and the planting work is carried out in this way.

[0026] Please see Figure 4 - Figure 5 A further solution based on this embodiment is as follows: the adjustment component includes a button 28 slidably connected to the rotating rod 22, a connecting plate 29 fixedly connected to the bottom of the button 28, a second spring 210 fixedly connected between the connecting plate 29 and the rotating rod 22, and a sliding block 211 slidably connected inside the rotating rod 22. The connecting plate 29 is slidably connected to the sliding block 211. By pressing the button 28, the connecting plate 29 is moved. When the connecting plate 29 moves, it drives the sliding blocks 211 on both sides to move. The sliding design of the button 28 facilitates quick adjustment by the operator. The sliding cooperation between the connecting plate 29 and the sliding block 211 can convert the linear movement of the button 28 into the lateral movement of the sliding block 211, thereby driving the locking component. At the same time, the second spring 210 can drive the button 28 and the connecting plate 29 to automatically reset after the pressing action is completed, without the need for manual reset, thus improving the ease of operation.

[0027] Please see Figure 4 - Figure 5 A further solution based on this embodiment is as follows: a sliding groove adapted to the connecting plate 29 is provided on the sliding block 211, and the connecting plate 29 is slidably connected to the sliding groove. The sliding groove provides a precise guiding path for the movement of the connecting plate 29, avoids the connecting plate 29 from deviating during the movement, and ensures that the connecting plate 29 can stably drive the sliding block 211 to move.

[0028] Please see Figure 4 - Figure 5A further solution based on this embodiment is as follows: the snap-fit ​​assembly includes a snap-fit ​​block 212 fixedly installed at one end of the sliding block 211, a third spring 213 fixedly connected between the snap-fit ​​block 212 and the rotating rod 22, and an mounting rod 214 fixedly installed on the duckbill plate 23. The mounting rod 214 is installed on the rotating rod 22, and the snap-fit ​​block 212 is snap-fitted onto the mounting rod 214. When the sliding block 211 moves, it drives the snap-fit ​​block 212 to move together. The snap-fit ​​structure between the snap-fit ​​block 212 and the mounting rod 214 can realize the quick fixation of the duckbill plate 23 and the rotating rod 22, ensuring that the two remain relatively stable during operation. When the sliding block 211 drives the snap-fit ​​block 212 to move, the snap-fit ​​state can be quickly released or locked. Specifically, in use, by pressing down the pressing button 28, the connecting plate 29 is moved by the pressing button 28, connecting... When plate 29 moves, it works in conjunction with the sliding groove on sliding block 211, causing the sliding blocks 211 connected to both sides to move. When sliding block 211 moves, it moves and releases the locking restriction of mounting rod 214 through the movement of locking block 212. Subsequently, by releasing the pressing button 28, the connecting plate 29 is reset by the second spring 210, and the locking block 212 is reset by the third spring 213. At the same time as the pressing button 28 is reset, the locking block 212 is reset and re-engaged with mounting rod 214, restoring the restriction on locking block 212 and realizing convenient disassembly and assembly of duckbill plate 23. During this process, the third spring 213 can provide pre-tightening force to locking block 212, enhancing the firmness of the locking. At the same time, it assists locking block 212 in resetting when the locking is released, improving the response speed and reliability of the locking assembly.

[0029] Please see Figure 4 - Figure 5 A further solution based on this embodiment is as follows: The limiting component includes a fixed base 215 fixedly installed on the rotating rod 22, an adjusting screw 216 rotatably connected to the fixed base 215, a sliding bracket 217 threadedly connected to the adjusting screw 216, and a limiting block 218 fixedly installed on the sliding bracket 217. The sliding bracket 217 is slidably connected to the fixed base 215, and the limiting block 218 is slidably connected to the push button 28. The adjusting screw 216 is used to adjust the movement of the sliding bracket 217. When the sliding bracket 217 moves, it drives the limiting block 218 to move. The threaded transmission structure of the adjusting screw 216 can realize the precise displacement adjustment of the sliding bracket 217. The position of the limiting block 218 can be controlled by rotating the screw. The operation is simple and the adjustment accuracy is high. After the limiting block 218 is connected to the push button 28, it can limit the movement stroke of the push button 28, avoid the push button 28 being accidentally touched after jamming, which would affect the installation of the duckbill plate 23 and improve the safety and applicability of the overall device.

[0030] Please see Figure 2 - Figure 3A further solution based on this embodiment is as follows: the driving component includes a first motor 219 fixedly installed on the main body 1 of the device, a rotating disk 220 fixedly connected to the output end of the first motor 219, a linkage rod 221 fixedly connected to the rotating disk 220, a fixed bracket 223 fixedly connected to the guide sleeve 21, and a linkage block 222 fixedly connected to the fixed bracket 223. The linkage rod 221 is slidably connected to the linkage block 222. The first motor 219 is used to drive the rotating disk 220 to rotate. When the rotating disk 220 rotates, it drives the fixed bracket 223 and the guide sleeve 21 to reciprocate through the linkage rod 221 and the linkage block 222. The first motor 219, as a power source, can provide a stable and continuous driving force. Through the cooperative structure of the rotating disk 220, the linkage rod 221 and the linkage block 222, the rotational motion of the motor is converted into the linear reciprocating motion of the guide sleeve 21.

[0031] Please see Figure 1 , Figure 6 A further embodiment of this solution is as follows: the film-coating assembly includes a film-coating roller 31 rotatably connected to the main body 1, a pressure roller 32 rotatably connected to the main body 1, a sliding support rod 33 slidably connected to the main body 1, a first pressing knob 34 threadedly connected to the sliding support rod 33, a second pressing knob 35 threadedly connected to the sliding support rod 33, a connecting rod 36 movably connected to the sliding support rod 33, and a pusher 37 fixedly installed at the bottom of the connecting rod 36. The pressure roller 32 is used to press and limit the protective film. When the main body 1 moves, the pusher 37 pushes the soil to cover both sides of the film, and the film-coating roller 31 can release the protective film, cooperating with the movement of the main body 1 to perform the film-coating operation. The wheel 32 can press and limit the protective film in real time during the film covering process to ensure the film is flat and improve the film covering quality. The sliding support rod 33, in cooperation with the first and second extrusion knobs 35, can flexibly adjust the height and angle of the pusher 37 to adapt to different film covering scenarios. The structural design of the first extrusion knob 34 and the second extrusion knob 35 is a common technical means in the field. By rotating the first extrusion knob 34 to extrude the main body 1 of the device, the position of the sliding support rod 33 is restricted. By rotating the second extrusion knob 35 to extrude the connecting rod 36, the position of the connecting rod 36 is restricted. The pusher 37 can quickly push the soil on both sides to the edge of the film after film covering, thereby achieving the coverage restriction of the film and preventing the film from being blown away or displaced by the wind.

[0032] Working principle: When in use, after the suspension bracket 5 of the main body 1 is installed on the self-propelled tracked or tire vehicle, the position of the sliding support rod 33 is adjusted by adjusting the first pressing knob 34 and the second pressing knob 35 on the sliding support rod 33 according to the usage requirements. After the pusher shovel 37 moves to the required position, the vehicle drives the main body 1 to move as a whole. During the movement of the main body 1, the film covering roller 31 releases the protective film, and the pressure roller 32 presses and limits the protective film in real time to ensure that the protective film covers the surface of the soil layer to be planted flat. When planting, the staff puts the pineapple seedling into the guide sleeve 21. The seedling slides down the guide sleeve 21 to its bottom. At this time, the duckbill plate 23 is in the closed state to prepare for the subsequent planting of the seedling. When the drive component is started, the first motor 219 drives the rotating disk 220 to rotate. When the rotating disk 220 rotates, it drives the fixed bracket 223 and the guide sleeve 21 connected to the fixed bracket 223 to move back and forth through the cooperation of the linkage rod 221 and the linkage block 222. When the guide sleeve 21 moves downward, it drives the rotating rod 22 and the duckbill plate 23 connected to the rotating rod 22 to move synchronously, so that the duckbill plate 23 passes through the protective film and inserts into the soil. As the guide sleeve 21 continues to move, the rotating rod 22 is squeezed by the squeezing rod 24, which causes it to rotate, thereby driving the duckbill plate 23 to open. During the opening process, the duckbill plate 23 pushes away the surrounding soil to form a pit, and the seedling falls into the pit. After completion, the guide sleeve 21 begins to reset. At this time, the first spring 27 pushes the rotating rod 22 to reset by elastic force. The reset of the rotating rod 22 drives the duckbill plate 23 to close. The guide sleeve 21 also continues to rise to the initial position, completing one planting action. Then, the above process of seedling insertion, duckbill plate 23 opening to release seedlings, and component reset is repeated to realize continuous planting of pineapple seedlings.

[0033] When the duckbill plate 23 needs to be replaced, the adjusting screw 216 is rotated to move the sliding bracket 217. The movement of the sliding bracket 217 causes the limiting block 218 to move, releasing the limitation block 218 from restricting the pressing button 28 in the adjusting assembly. Then, by pressing the pressing button 28, the connecting plate 29 fixedly connected to the bottom is moved, and the movement of the connecting plate 29 causes the sliding block 211 to move. When the sliding block 211 moves, it causes the locking block 212 fixedly installed at one end to move synchronously, moving the locking block 212 away from the installation. After releasing the latch on rod 214, the old duckbill plate 23 can be removed and replaced with a new duckbill plate 23. After replacement, release the button 28. The second spring 210 between the connecting plate 29 and the rotating rod 22 will drive the button 28 and the connecting plate 29 to reset. The sliding block 211 will reset with the connecting plate 29. The latching block 212 will reset under the elastic force of the third spring 213 and re-latch with the mounting rod 214 of the new duckbill plate 23. Finally, adjust the limiting component so that the limiting block 218 restricts the button 28 again, completing the replacement of the duckbill plate 23.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
