Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a corn planting and seeding machine. Background Technology

[0002] In modern agricultural production, burying drip irrigation tape in the soil during corn planting offers numerous advantages. For example, drip irrigation tape delivers water directly to the deep soil layers around the corn roots, avoiding surface evaporation and deep seepage associated with traditional irrigation, significantly improving water resource utilization. Fertilizer is dissolved and precisely injected into the root zone with the drip irrigation water, reducing nutrient loss. Low-pressure drip irrigation prevents soil compaction, maintains porosity and aeration, and promotes root development. Drip irrigation systems can be automated, reducing manual labor for irrigation and fertilization, resulting in significant benefits for large-scale planting.

[0003] In actual installation, after corn planting, trenches are dug between rows of corn, and then drip irrigation tape is laid and covered. Although some existing equipment can achieve the above function, problems still exist. For example, prior art with publication number CN218649186U discloses a fertilizable corn planter, including a main frame and at least one set of rotary tillage mechanism, fertilization mechanism, seed metering mechanism, and drip irrigation mechanism. The main frame has upper and lower mounting plates on both sides, and each set of fertilization mechanisms is mounted on the upper mounting plate. The rotary tillage mechanisms described in each group are all mounted on the lower mounting plate. The seeding mechanism and the drip irrigation mechanism in each group are set on the main frame through a connecting rod assembly. The main frame is also equipped with a traction frame. Although it can complete a series of processes such as clearing the ridges and opening the furrows, fertilizing, sowing, compacting, and shallow burying the drip irrigation tape in one go, when burying the drip irrigation tape, it can only simply gather the soil on both sides of the drip irrigation tape to the surface of the drip irrigation tape, which will form a soil ridge that is not compacted enough. It is easy for the soil to be blown away by the wind, causing the drip irrigation tape to be exposed and resulting in weathering and damage to the drip irrigation tape. Summary of the Invention

[0004] Based on this, this application provides a corn planting machine to solve the technical problem in the prior art where the drip irrigation tape is not buried tightly enough, resulting in the drip irrigation tape being exposed to the outside world and becoming weathered and damaged.

[0005] The technical solution to the above-mentioned technical problems in this application is as follows:

[0006] A corn planting and seeding machine, comprising:

[0007] A rotary tillage assembly, connected to a traction device, is used for rotary tilling of the soil;

[0008] A seeding assembly, disposed behind the rotary tillage assembly, is used for seeding;

[0009] An installation component is disposed on the rear side of the rotary tillage component for burying the drip irrigation tape in the soil; the installation component includes a burying part that can smooth the soil ridge after the drip irrigation tape is buried.

[0010] Multiple seeding components and multiple burying components are provided, with a burying component distributed between every two adjacent seeding components.

[0011] Preferably, the burying component further includes a dragging part connected to the rear side of the rotary tillage component, and a lifting part is provided between the dragging part and the burying part, the lifting part being able to drive the burying part to conform to the soil.

[0012] Preferably, it also includes a trenching section for excavating a trench for burying the drip irrigation tape, the trenching section being connected to the lifting section, and the burying section being connected to the trenching section.

[0013] Preferably, the lower end of the trenching section is provided with a flattening section for flattening the bottom of the trench created by the trenching section.

[0014] Preferably, it also includes an unwinding section, which is disposed on the dragging section for carrying the drip irrigation tape, and the lifting section and the burying section can guide the drip irrigation tape into the trench.

[0015] Preferably, the burial part includes a U-shaped groove connected to the trench, and a backfill claw hinged to the upper side of the inner wall of the rear end of the U-shaped groove by a torsion spring. The drip irrigation tape is inserted from the front end of the U-shaped groove and exits from the rear end of the U-shaped groove and below the backfill claw. The claw tip of the backfill claw extends downward out of the inclined wall.

[0016] Preferably, two crossbars are connected to the upper side of the inner wall of the front end of the U-shaped groove, and each crossbar is rotatably connected to a pressure roller. The crossbar located on the front side is fixed to the inner wall of the U-shaped groove, and the crossbar located on the rear side is slidably connected to an elongated hole opened on the inner wall of the U-shaped groove. A tension spring is connected between the outer ends of the two crossbars, and the drip irrigation tape is inserted into the U-shaped groove between the two pressure rollers.

[0017] Preferably, the grooved part includes a vertical pipe, and a rotating seat is rotatably connected to the side wall of the lower front side of the vertical pipe. Each rotating seat is provided with a grooved piece. The two grooved pieces are close to the middle in both the vertical and horizontal directions, and the foremost sides of the two grooved pieces are in contact with each other. The front end of the U-shaped groove is connected to the rear side of the lower end of the vertical pipe.

[0018] Preferably, the leveling part includes a vertical rod slidably connected inside the vertical pipe. The vertical rod is fixed inside the vertical pipe by a tightening bolt. A flat plate is formed at the lower end of the vertical rod, and the front end of the flat plate is inclined upward to guide the soil to the bottom of the flat plate.

[0019] Preferably, the dragging part includes a bracket, which is divided into a horizontal section and a vertical section. The horizontal section is provided with a connecting frame A and a connecting frame B at both ends. The connecting frame A is used to connect with the traction device. The unwinding part is connected to the connecting frame B. The vertical section has several circular holes along its extension direction. The lifting part is connected to the circular holes.

[0020] Compared with the prior art, this application has at least the following advantages:

[0021] This application provides a corn planting machine that uses a traction device to move a rotary tiller assembly in the field, causing the rotary tiller assembly to till the soil and loosen it. Then, multiple seeding assemblies following behind the rotary tiller assembly sow corn seeds into the soil, resulting in multiple rows of sown corn seeds. Next, a burying assembly carries multiple drip irrigation tapes that follow behind the seeding assemblies. By using the spacing between the burying assembly and the seeding assemblies, the drip irrigation tapes are laid between every two adjacent corn rows, and soil is covered on the drip irrigation tapes. Finally, the burying part compacts the soil covering the drip irrigation tapes. This method can compact the soil covering the drip irrigation tapes after they are laid, avoiding the situation where the soil is simply covered and then blown away by wind or other factors (such as animal trampling), thus preventing the drip irrigation tapes from being exposed to the outside world and suffering severe weathering.

[0035] Please refer to Figures 1 to 9 In one specific embodiment of this application,

[0036] A corn planting and seeding machine, comprising:

[0037] Rotary tillage assembly 100, which is connected to a traction device and is used for rotary tillage of soil;

[0038] A seeding assembly 200 is disposed on the rear side of the rotary tillage assembly 100 and is used for seeding;

[0039] The burying component 300 is disposed on the rear side of the rotary tillage component 100 and is used to bury the drip irrigation tape in the soil; the burying component 300 includes a burying part 310, which can smooth the soil ridge after the drip irrigation tape is buried.

[0040] Multiple seeding components 200 and multiple embedding components 300 are provided, with one embedding component 300 distributed between every two adjacent seeding components 200.

[0041] Among them, the rotary tillage component 100 can be a rotary tiller or a plow, which is suspended on a traction device, such as a tractor, and moves by the traction device to turn the soil and make the soil loose.

[0042] The seeding component 200 can be a corn planter, which is suspended behind the rotary tillage component 100 and moves together to sow the seeds in the loose soil.

[0043] The installation component 300 can be a device that covers soil onto the laid drip irrigation tape, or it can guide soil near the drip irrigation tape to a push plate on the drip irrigation tape.

[0044] The burial section 310 can be a pressure roller or a pressure plate, which can compact the soil covering the drip irrigation tape.

[0045] In actual operation, the rotary tillage component 100 is moved in the field by the traction device, so that the rotary tillage component 100 tills the soil and makes the soil loose. Then, the corn seeds are sown into the soil by the multiple seeding components 200 following behind the rotary tillage component 100, so that multiple rows of corn seeds are sown. Then, the burying component 300 carries multiple drip irrigation tapes and moves behind the multiple seeding components 200. By using the interval distribution between the burying component 300 and the seeding components 200, the drip irrigation tapes are laid between every two adjacent corn rows and the soil is covered on the drip irrigation tapes. Finally, the burying part 310 is used to compact the soil covering the drip irrigation tapes.

[0046] By using the above method, the soil covering the drip irrigation tape can be compacted after the drip irrigation tape is laid, avoiding the soil being simply covered and causing it to fall apart due to wind or other factors (such as animal trampling), thus preventing the drip irrigation tape from being exposed to the outside world and becoming severely weathered.

[0047] In actual use, because the soil is rotary tilled and the soil in different parts of the field is different, the drip irrigation tape will have different heights in different places. Therefore, when burying the drip irrigation tape, it is also necessary to control the soil burying thickness, otherwise there will be some places with thin soil burying and some places with too much soil.

[0048] Therefore, in this application, the burying component 300 also includes a dragging part 350 connected to the rear side of the rotary tillage component 100, and a lifting part 340 is provided between the dragging part 350 and the burying part 310, the lifting part 340 being able to drive the burying part 310 to conform to the soil.

[0049] The drag unit 350 can be a frame or a rod that can be connected to the rear of the rotary tiller assembly 100. The lifting unit 340 can be an electric telescopic rod or a spring-type connector. In use, the drag unit 350 is connected to the rear of the rotary tiller assembly 100, the lifting unit 340 is installed behind the drag unit 350, and the burying part 310 is connected to the lifting unit 340. During tillage, after the drip irrigation tape is laid on the soil, the burying part 310 adheres to the soil, allowing the lifting unit 340 to move freely. The burying part 310 is adjusted to adapt to the different positions of the drip irrigation tape, thereby controlling the distance between the burying part 310 and the drip irrigation tape. This ensures that the thickness of the soil laid on the drip irrigation tape is as uniform as possible after being buried and compacted by the burying part 310. This avoids the problem of the drip irrigation tape being easily exposed in some places where the soil burying is weak, and also avoids the drip irrigation tape being subjected to excessive weight due to too much soil in some places. This prevents the soil from flattening the drip irrigation tape and causing the internal water flow to be blocked or obstructed.

[0050] If the drip irrigation tape is laid on the soil surface and then buried, a ridge will be formed, which will result in the drip irrigation tape being laid far from the corn roots in the soil.

[0051] Therefore, this application also includes a trenching section 320 for excavating a trench for burying the drip irrigation tape. The trenching section 320 is connected to the lifting section 340, and the burying section 310 is connected to the trenching section 320.

[0052] The furrowing section 320 can be a furrow opener on an existing seeder (in the form of two furrowing plates 323 below), or it can be a tool that can open furrows in the soil. During use, the furrowing section 320 is connected to the forward side (the side on which the traction device moves forward) at the lower end of the lifting section 340. Then, as the traction device moves forward, the lifting section 340 can be moved forward together by the drag section 350. During this process, the furrowing section 320 at the lower end of the lifting section 340 is inserted into the soil, and a furrow can be dug in the soil as the furrowing section 320 moves forward. Then, the drip irrigation tape is laid into the furrow and buried.

[0053] By using the above method, trenches can be dug in the soil so that the drip irrigation tape is buried below the surface. This allows the drip irrigation tape to be closer to the corn roots after burial, enabling water and fertilizer to be delivered more quickly. This closer proximity promotes growth at the corn roots.

[0054] In addition, the trenches are generally funnel-shaped with a small bottom and a large top. If the bottom space is too small after the drip irrigation tape is laid, or if there are protruding stones or other impurities in the trench, the drip irrigation tape may become crooked or be damaged during compaction.

[0055] Therefore, in this application, the lower end of the trenching part 320 is provided with a flattening part 330, which is used to flatten the bottom of the trench opened by the trenching part 320.

[0056] The flattening part 330 can be a flat plate or a pressure roller, which can flatten the bottom of the groove when it comes into contact with it. In practical applications, the groove is opened in front of the grooving part 320, and then the flattening part 330 is brought forward to contact the bottom of the groove and flatten it, making the bottom of the groove more flat.

[0057] By using the above methods, the bottom of the trench can be trimmed when laying the drip irrigation tape, making the bottom of the trench flatter and preventing protruding stones from damaging the drip irrigation tape after it is laid. At the same time, it can also prevent the drip irrigation tape from twisting or turning in the trench if the bottom is too small.

[0058] In order to improve the level of automation and smoothly guide the drip irrigation tape into the trench for laying, this application also includes an unwinding part 360, which is disposed on the dragging part 350 and is used to carry the drip irrigation tape. The lifting part 340 and the burying part 310 can guide the drip irrigation tape into the trench.

[0059] The unwinding section 360 can be a rotating frame that can hold the rolled drip irrigation tape. When the end of the drip irrigation tape is pulled out, the rolled drip irrigation tape can rotate on the unwinding section 360, allowing the drip irrigation tape to unfold smoothly. Then, the end of the drip irrigation tape passes through the lifting section 340 and the burying section 310 in sequence, and finally fixes the end of the drip irrigation tape in the trench and secures it. Then, as the traction equipment moves forward, the unwinding section 360 moves away from the end of the drip irrigation tape along with the dragging section 350. This allows the unwinding section 360 to automatically unfold and, guided by the lifting section 340 and the burying section 310, enter the trench to complete the laying.

[0060] Specifically, an embodiment is provided for the burial section 310 in the above process:

[0061] The burial section 310 includes a U-shaped groove 311 connected to the trench section 320, and a backfill claw 312 hinged to the upper side of the inner wall of the rear end of the U-shaped groove 311 by a torsion spring. The drip irrigation tape is inserted through the front end of the U-shaped groove 311 and exits through the rear end of the U-shaped groove 311 and below the backfill claw 312. The claw tip of the backfill claw 312 extends downward to form an inclined wall 313.

[0062] In practical use, the front end of the U-shaped groove 311 is connected to the rear side of the lifting unit 340. Then, the drip irrigation tape is inserted through the front end of the U-shaped groove 311 and exits through the rear end of the U-shaped groove 311 and below the backfilling claw 312. As the traction equipment moves forward, the trenching unit 320 can open the trench and the bottom of the trench can be leveled by the leveling unit 330. As the U-shaped groove 311 moves with the lifting unit 340, the U-shaped groove 311 and the trench are on the same straight line. The drip irrigation tape that has exited through the rear end of the U-shaped groove 311 can be laid in the trench. During this process, the backfilling claw 312 can backfill the soil piled up on both sides of the trench into the trench. At this time, the two inclined walls 313 span the sides of the trench and use the downward-extending inclined walls 313 to make the soil that has passed gather towards the middle and backfill into the trench. Then, the backfilling claw 312 is used to smooth the backfilled soil, completing the burial of the drip irrigation tape.

[0063] Additionally, the torsion spring between the backfill claw 312 and the U-shaped groove 311 can always apply a downward force to the backfill claw 312 during this process, so that the backfill claw 312 can maintain a downward pressing tendency to compact the soil backfilled into the trench for burial, thereby compacting the soil covering the drip irrigation tape and preventing it from scattering.

[0064] Furthermore, two crossbars 315 are connected to the upper side of the inner wall of the front end of the U-shaped groove 311, and each crossbar 315 is rotatably connected to a pressure roller 314. The crossbar 315 located on the front side is fixed to the inner wall of the U-shaped groove 311, and the crossbar 315 located on the rear side is slidably connected to the elongated hole 316 opened on the inner wall of the U-shaped groove 311. A tension spring 317 is connected between the outer ends of the two crossbars 315, and the drip irrigation tape is inserted into the U-shaped groove 311 between the two pressure rollers 314.

[0065] As the drip irrigation tape passes through the two pressure rollers 314 from top to bottom, the tension spring 317 pulls the two crossbars 315 to keep them clamped, thus clamping the drip irrigation tape between the two pressure rollers 314. When the drip irrigation tape turns backward in the U-shaped groove 311, it contacts the pressure roller 314 located on the rear side. As the drip irrigation tape continues to pass through, the friction force can cause the two pressure rollers 314 to rotate relative to each other. This avoids scratching the drip irrigation tape due to hard friction when guiding it to turn. The two pressure rollers 314 can also clamp the drip irrigation tape and apply pressure to the drip irrigation tape from both sides to expel the air inside the drip irrigation tape. This prevents the drip irrigation tape from having a large volume due to air in it, which would push up the surface soil and reduce the amount of soil covering when it is buried.

[0066] Specifically, an embodiment is provided for the trenching section 320 in the above process:

[0067] The grooved section 320 includes a vertical tube 321. A rotating seat 322 is rotatably connected to the side wall of the lower front side of the vertical tube 321. Each rotating seat 322 is provided with a grooved piece 323. The two grooved pieces 323 are close to the middle in both the vertical and horizontal directions, and the foremost sides of the two grooved pieces 323 are in contact with each other. The front end of the U-shaped groove 311 is connected to the rear side of the lower end of the vertical tube 321.

[0068] The vertical pipe 321 is connected to the lifting unit 340. As the towing unit 350 moves forward with the traction equipment, the vertical pipe 321 will drive the two trenching plates 323 at the lower end to move forward. At this time, the "cone tip" formed by the front side of the two trenching plates 323 will split the soil after rotary tillage, so that the soil separates on both sides when it comes into contact with the outer side of the two trenching plates 323. The two trenching plates 323 extend into the soil to dig trenches. Then, the U-shaped groove 311 guides the pipe into the trench from the rear side of the vertical pipe 321. At the same time, when the two trenching plates 323 come into contact with the soil, the friction between them can drive the rotating seat 322 to rotate, so that the trenching plates 323 work in the soil in a rolling manner. The trenching plates 323 can be supported in the soil, thereby transferring the overall weight to the soil and playing a supporting role.

[0069] The above method enables the process of digging trenches in the soil, and the rolling of the trenching plate 323 increases the overall support, thereby reducing the force on the rotary tillage assembly 100 when the drag part 350 is connected to the rotary tillage assembly 100, and improving stability.

[0070] Specifically, an embodiment of the flattening section 330 in the above process is provided:

[0071] The leveling part 330 includes a vertical rod 331 slidably connected to the vertical tube 321. The vertical rod 331 is fixed to the vertical tube 321 by a tightening bolt. A flat plate 332 is formed at the lower end of the vertical rod 331. The front end of the flat plate 332 is inclined upward to guide the soil to the area below the flat plate 332.

[0072] The vertical rod 331 is slidably connected inside the vertical pipe 321, allowing the distance between the plate 332 at the lower end of the vertical rod 331 and the lower end of the vertical pipe 321 to be changed. Thus, when the two trenching plates 323 are digging a trench, by adjusting the height of the plate 332 and then fixing the vertical rod 331 to the vertical pipe 321 with tightening bolts, different trench bottom depths can be obtained. In other words, the depth of the trench dug by the two trenching plates 323 is fixed, and since the trench is funnel-shaped, the lower the plate 332 (…), the greater the depth of the trench. The greater the distance between the plate 332 and the lower end of the vertical pipe 321, the closer it is to the bottom of the trench. Conversely, the higher the plate 332 is, the closer it is to the top of the trench. The different depths of the plate 332 in the trench will create trenches with flat ground and different depths. At the same time, the front end of the plate 332 is inclined upwards. When the plate 332 moves forward, the soil that comes into contact with the front end of the plate 332 will be guided by the inclined surface to pass under the plate 332. The lower end of the plate 332 will be used to smooth and compact the bottom of the trench.

[0073] By using the above methods, not only can the burial depth of the drip irrigation tape be controlled during actual operation, but the bottom of the trench can also be trimmed to make the bottom of the trench flat, making the laying of the drip irrigation tape smoother.

[0074] Specifically, an embodiment is provided for the drag-and-drop unit 350 in the above process:

[0075] The dragging part 350 includes a bracket 351, which is divided into a horizontal section and a vertical section. The horizontal section is provided with a connecting frame A353 and a connecting frame B352 at both ends. The connecting frame A353 is used to connect with the traction device. The unwinding part 360 is connected to the connecting frame B352. The vertical section has several circular holes along the extension direction. The lifting part 340 is connected to the circular holes.

[0076] The connecting frame A353 can be a snap-on or other connecting parts. Connecting the connecting frame A353 to the rotary tillage assembly 100 (for example, the bracket or pit crossbeam on the rear side of the rotary tiller) allows for the installation of the drag section 350. At the same time, the unwinding section 360 is connected to the connecting frame B352 for easy carrying of the drip irrigation tape. The lifting section 340 is connected to the vertical section, and several round holes are used to achieve different height positions for installation.

[0077] Specifically, an embodiment of the lifting unit 340 in the above process is provided:

[0078] The lifting part 340 includes a sleeve 341 with a guide sleeve 342 fixed to the rear side, and two sets of arc arms 343 rotatably connected to the front side of the sleeve 341 and distributed vertically. Each set of arc arms 343 includes two arc arms 343. The front ends of the two arc arms 343 are rotatably connected to the circular hole through a rotating shaft 344. A torsion spring is provided between the rotating shaft 344 and the circular hole. Multiple limiting holes 346 are opened on the arc arms 343 along the front-back direction. The lifting part 340 also includes a limiting shaft 345 that can be inserted into the corresponding two limiting holes 346.

[0079] The vertical pipe 321 is slidably connected in the sleeve 341 and fixed by a tightening bolt. The torsion spring applies a downward rotational force to the rotating shaft 344. The two sets of arc-shaped arms 343 are installed in a parallel state, meaning the distance between the two rotating shafts 344 in the height direction is the same as the distance between the two sets of arc-shaped arms 343. At this time, the vertical section between the two sets of arc-shaped arms 343, the two sets of arc-shaped arms 343, and the sleeve 341 between the two sets of arc-shaped arms 343 form a parallelogram structure, with the trenching plate 323 supported on the soil. When the ditching plate 323 rolls, it pushes the vertical tube 321 upward with the undulation of the soil, thereby causing the vertical tube 321 to drive the sleeve 341 to rise. During this process, the rotating shaft 344 at the front end of the arc arm 343 rotates and compresses the torsion spring, causing the torsion spring to store force. The downward force applied by the torsion spring to the rotating shaft 344 can cause the rotating shaft 344 to drive the arc arm 343 to maintain downward pressure, thereby causing the sleeve 341 to drive the vertical tube 321 to keep the ditching plate 323 always in contact with the soil. This process and effect can be achieved by adjusting the ditching plate according to the undulation of the soil.

[0080] Alternatively, by inserting the limiting shaft 345 into any of the limiting holes 346, when the arc arm 343 rotates downwards, it will stop rotating downwards when the limiting shaft 345 contacts the sleeve 341. Conversely, when the arc arm 343 rotates upwards, it will stop rotating when the limiting shaft 345 contacts the sleeve 341. This allows for control of the rotation range of the arc arm 343. By utilizing this, the sleeve 341 can be restricted in its range during undulation, thus keeping the undulation of the furrowing plate 323 within a fixed range. This controls the opening of the furrows to avoid excessive height fluctuations, which could lead to excessive height differences in the drip irrigation tape on the horizontal plane. It also prevents the accumulation of water and fertilizer in the drip irrigation tape due to excessive height differences (for example, when the drip irrigation tape bends up and down, the residual water and fertilizer will concentrate at the bottom of the downward bend; figuratively speaking, in a wavy drip irrigation tape, water and fertilizer will concentrate at the trough, causing the water and fertilizer near the trough to flow out and cause excessive nutrients in the surrounding soil).

[0081] Specifically, an embodiment is provided for the unwinding section 360 in the above process:

[0082] The unwinding section 360 includes a bracket 361 connected to the connecting frame B352. The bracket 361 has a U-shaped structure and an insert shaft 362 that can be inserted into the upper end of the bracket 361. A turntable 363 is fitted on the insert shaft 362 and the turntable 363 can rotate on the insert shaft 362. The end of the insert shaft 362 extends out of the bracket 361 and has a through hole. A pin 364 is connected in the through hole.

[0083] During use, the turntable 363 with drip irrigation tape wound around it can be placed into the bracket 361. Then, the insert shaft 362 is inserted from one side of the bracket 361, passes through the turntable 363, and then exits from the other side of the bracket 361. Then, the pin 364 is inserted into the through hole to complete the installation, which can carry the drip irrigation tape. When laying, the end of the drip irrigation tape is manually driven from top to bottom through the guide sleeve 342. The guide sleeve 342 guides the drip irrigation tape to extend downward. Then, the drip irrigation tape passes through the two pressure rollers 314 and then passes backward through the rear end of the U-shaped groove 311 and below the backfill claw 312. Finally, the end of the drip irrigation tape is fixed in the trench. Then, as the traction equipment moves forward, the laying of the drip irrigation tape is completed.

[0084] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
