Description

Technical Field

[0001] This invention relates to the field of corn planting technology, specifically to a dryland corn V-furrow planter and its planting method. Background Technology

[0002] In actual dryland maize planting, V-groves are created on the ground to collect localized rainfall at the bottom of the groves, increasing soil moisture content in the seed or root zone and improving water utilization. Covering the bottom of the groves with film further reduces evaporation. Typically, V-groves are spaced three meters apart, and maize seeds are sown between them. V-grove planters are widely used due to their high sowing efficiency. However, when the seeding wheel of current planters rotates to release seeds, some larger seeds and seeds mixed with sand and gravel are prone to getting stuck, making it difficult to automatically control the disconnection and stop the sowing process. At the same time, as seeds in the seed box are consumed, if manual replenishment is not detected in time, the continuous movement of the tractor can easily cause gaps, requiring cumbersome retraction of the planter or manual reseeding. Manually searching for the stopping position is tedious and does not facilitate the automatic disconnection of the tractor to ensure sowing continuity. Grooved sowing can also easily cause the V-groves to collapse due to compression, which affects the subsequent rainwater collection and moisture retention effect and makes it difficult to protect the V-groves.

[0003] Therefore, we propose a V-furrow planter for dryland maize and its planting method. Summary of the Invention

[0014] A method for planting maize in V-furrows in dryland areas: 1) The trailer is bolted to the tractor for towing and movement. Seeds are filled into the seed box, and the drive motor drives the drive disc to rotate back and forth for sowing. 2) When the V-ditch collapses, soil accumulates at the bottom of the V-ditch. The wall cover rolls and adheres to the bottom of the V-ditch, which will drive the swing arm to rotate and move upward, approach and squeeze the micro switch, and control the indicator light to light up as a warning.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention employs a drive device that works in conjunction with a seed storage and dispensing unit to achieve equidistant sowing and dispensing, ensuring proper plant spacing. Simultaneously, the structure utilizes a jamming switch for jam detection. If jamming occurs during actual seed dispensing, the dispensing process automatically stops, preventing damage to the sowing wheel or seed box caused by continuous dispensing of large-diameter seeds or gravel. Furthermore, a disconnection control unit promptly disconnects the tractor in case of jamming, alerting personnel for timely maintenance.

[0016] The downward pressure auxiliary component can be used to detect seed inventory, preventing seed sowing interruptions caused by insufficient seed inventory and failure to replenish the seed in time while the tractor continues to move, resulting in sowing gaps. The use of a trailer connector in conjunction with a disconnection control component can automatically disconnect the connection with the tractor when the seed inventory is insufficient, ensuring that the seed sowing stop position is more clearly defined, eliminating the need for manual searching and replanting. This also avoids the risk of the V-groove on the ground being squeezed and collapsed when the traditional tractor drives the seeder back.

[0017] The swing arm fitting component can be used to fit the side of the V-groove in real time, which can improve the safety of the trenching pear when trenching near the edge of the V-groove and prevent the soil from collapsing under the pressure of the trenching pear. Once the V-groove collapses, this structure can automatically prompt that the V-groove needs to be maintained, without the need for tedious manual measurement. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] The sowing support component 1 includes: a soil covering plate 104, wheels 105, micro switches 106, and indicator lights 107. A row of soil covering plates 104 is fixedly installed at the bottom of the sowing support component 1, and each row of soil covering plates 104 is aligned with a row of furrowed pears 102. Two wheels 105 are rotatably installed at the rear of the box frame 101 via a bracket. Micro switches 106 are fixedly installed on both sides of the box frame 101, and indicator lights 107 are connected to the two micro switches 106 via wires. The two indicator lights 107 are connected in series with the two micro switches 106 for power supply. The seed storage and discharge component 2 includes: a seed box 201, a sowing wheel 202, and a connecting shaft 2021. A row of seed boxes 201 is fixedly installed on the box frame 101. A sowing wheel 202 is rotatably sleeved at the bottom of each row of seed boxes 201, and the sowing wheel 202 has two grooves for discharging seeds. A connecting shaft 202 is rotatably connected to each row of seed boxes 201. 1. A row of seeding wheels 202 is fixedly installed on the connecting shaft 2021; the driving device 3 includes: a drive motor 301, an anti-misoperation torsion spring 3011, a drive disk 302, a protrusion 303, and a locking switch 304. The drive motor 301 is fixedly installed at the bottom of the frame 101; the drive disk 302 is rotatably sleeved on the output shaft of the drive motor 301, and the side of the drive disk 302 is fixedly installed at the end of the connecting shaft 2021; a protrusion 303 is fixedly installed on the output shaft of the drive motor 301; a groove is provided on the drive disk 302; the protrusion 303 is located in the groove on the drive disk 302; two locking switches 304 are fixedly installed on the protrusion 303, and the locking switches 304 are used to press and fit the inner side of the drive disk 302; an anti-misoperation torsion spring 3011 is sleeved on the output shaft of the drive motor 301, and the anti-misoperation torsion spring 3011 is connected between the drive disk 302 and the output shaft of the drive motor 301.The front-side jamming switch 304 is electrically connected to the drive motor 301, and the drive motor 301 is externally connected to a controller. The drive device 3, in conjunction with the seed storage and discharging component 2, enables equidistant sowing and discharging, ensuring proper plant spacing. Simultaneously, the jamming switch 304 allows for jam detection; if jamming occurs during actual seed discharging, the discharging will automatically stop, preventing damage to the sowing wheel 202 or seed box 201 caused by continuous discharging of large-diameter seeds or gravel. The structure is simple and rationally designed, allowing for rapid control via the drive device 3. Furthermore, in conjunction with the disconnection control component 5, it can detect jamming in case of a jamming event. Timely disconnection from the tractor can prompt staff to perform timely maintenance. Seeds are filled into the seed box 201, and the drive motor 301 drives the drive disc 302 to rotate reciprocally. An anti-accidental contact torsion spring 3011 provides elastic connection, resulting in low resistance during normal seed discharge. This drives the sowing wheel 202 to rotate, using the grooves on the sowing wheel 202 to discharge the seeds, thus achieving sowing. During this process, the tractor drives this structure to move at a constant speed, achieving equidistant sowing. If seeds exceeding the particle size limit are scraped from the grooves on the sowing wheel 202, or if sand or gravel impurities are present, the front-side locking switch 304 can control the drive motor 301 to stop first, preventing further losses.

[0023] The pressing auxiliary component 4 includes: a pressing connecting shaft 401, a tension spring 402, a pressing plate 403, a push plate 404, a seed shortage switch 405, and a seed-adding electromagnet 406. A row of pressing connecting shafts 401 are slidably inserted into the plug-in bracket 103, and the structure of the row of pressing connecting shafts 401 is the same. A tension spring 402 is sleeved on the pressing connecting shaft 401, and the tension spring 402 is connected between the pressing connecting shaft 401 and the plug-in bracket 103. A pressing plate 403 is fixedly installed at the bottom of the pressing connecting shaft 401, and the pressing plate 403... Located inside the seed box 201; a push plate 404 is slidably connected to the bottom of the lower pressure plate 403, and the top of the push plate 404 is connected to the inside of the lower pressure plate 403 by two springs; a seed shortage switch 405 is fixedly installed on the top of the push plate 404, and the end of the seed shortage switch 405 is attached to the inner side of the lower pressure plate 403; a seed adding electromagnet 406 is fixedly installed on the top of the lower pressure plate 403, and the seed adding electromagnet 406 is used to magnetically attract the push plate 404; a switch is externally connected to the seed adding electromagnet 406; the disconnection control component 5 includes: a connecting sleeve 501 and a positioning pin 5. 02. A limiting spring 503 and a disconnecting electromagnet 504 are fixedly mounted on the frame 101 via a connecting sleeve 501. Two positioning pins 502 are slidably inserted into the connecting sleeve 501. A limiting spring 503 is fitted onto each of the two positioning pins 502, and the limiting spring 503 is connected between the connecting sleeve 501 and the positioning pins 502. Two disconnecting electromagnets 504 are fixedly mounted on the connecting sleeve 501 via a bracket, and the two disconnecting electromagnets 504 are respectively aligned with the two positioning pins 502. The disconnecting electromagnets 504 are electrically connected to the rear side. A latching switch 304; a disconnect electromagnet 504 electrically connected to a row of missing type switches 405; a tow connector 6 including: a plug post 601 and a tow frame 602, the plug post 601 being used to slide up and down on the tow frame 602 to help improve the adaptability of this structure to small undulations in the ground, the plug post 601 being slidably inserted into the connecting sleeve 501; two positioning pins 502 being slidably inserted into the plug post 601 respectively; the tow frame 602 having a groove; the tail of the plug post 601 being slidably mounted up and down on the groove on the tow frame 602;The trailer 602 has three through holes. A downward-pressing auxiliary component 4 can be used to press down and adhere the seeds, promoting seed adhesion to the sowing wheel 202 for release. It can also be used to detect seed level, preventing sowing interruptions due to insufficient seed level, which could result in missed sowing opportunities if manual replenishment is not detected while the tractor continues to move. The trailer connector 6, in conjunction with the disconnection control component 5, automatically disconnects from the tractor when seed level is insufficient. Even if the tractor moves forward a certain distance, this structure will stop moving, allowing the tractor to simply reverse. This ensures a clearer stopping point for seed sowing, eliminating the need for manual searching or reseeding. The structure is more rational and avoids the common problem of tractor-driven seeders collapsing the V-grooves when reversing. If the seed box 201 collapses, and the seed quantity is low, the bottom of the seed box 201 has a sloping structure. When the pressure plate 403 stops moving downwards, there is still a gap between it and the sowing wheel 202. At this time, the seeds no longer stop the push plate 404. With the help of the spring on the push plate 404, the switch 405 is no longer squeezed, which controls the disconnection electromagnet 504 to electromagnetically attract the positioning pin 502, stretching the limit spring 503 and pulling it out from the plug-in post 601, thus separating the plug-in post 601 from the connecting sleeve 501. The seed box 201 will be left on the ground to prevent it from moving continuously with the tractor. Later, when the tractor is reversed, the plug-in post 601 can be re-inserted into the connecting sleeve 501. Similarly, if the locking switch 304 on the rear side is squeezed and seeds get stuck, it can also control the disconnection electromagnet 504 to electromagnetically attract the positioning pin 502 to perform the disconnection operation.

[0024] In Embodiment 2, based on Embodiment 1, the swing arm fitting component 7 includes: a swing arm 701, a rotating shaft 7011, and a connecting shaft 702. The rotating shaft 7011 is rotatably fitted onto the swing arm 701, and the end of the rotating shaft 7011 is fixedly mounted on the frame 101. A torsion spring is fitted onto the rotating shaft 7011, and the torsion spring on the rotating shaft 7011 is connected between the rotating shaft 7011 and the swing arm 701. The connecting shaft 702 is fixedly mounted at the bottom of the swing arm 701. The swing arm 701 is aligned with the micro switch 106. The swing arm fitting component 7 also includes: a wall-mounting spring 703 and a wall-mounting cover 704. The side of the wall-mounting cover 704 has a beveled structure. The wall-mounting spring 703 is fitted onto the connecting shaft 702. The wall-mounting cover is rotatably fitted onto the connecting shaft 702. 704, the end of the wall-mounted spring 703 is attached to the wall-mounted cover 704; the wall-mounted cover 704 is used to adhere to the side wall of the V-groove. The swing arm fitting 7 can be used to adhere to the side of the V-groove in real time, which can improve the safety of the trenching pear 102 when trenching near the edge of the V-groove, and avoid soil collapse under the pressure of the trenching pear 102. The V-groove will need to be repaired later. The structure is simple and reasonable. At the same time, the wall-mounted spring 703 compresses the wall-mounted cover 704, which can improve adaptability. In addition, the side of the V-groove is a sloping structure. Once the side of the wall-mounted cover 704 is also sloping and attached to the side wall of the V-groove, if excessive collapse occurs, this structure can automatically prompt that V-groove maintenance work is needed, without the need for tedious manual measurement and inspection.

[0025] A method for planting maize in V-furrows in dryland areas: 1) The trailer 602 is bolted to the tractor for towing and movement. Seeds are filled in the seed box 201, and the drive motor 301 drives the drive disc 302 to rotate back and forth for sowing. 2) When the V-ditch collapses, soil accumulates at the bottom of the V-ditch. The wall cover 704 rolls and adheres to the bottom of the V-ditch, which drives the swing arm 701 to rotate and move upward, approaching and pressing the micro switch 106, and the control indicator light 107 lights up to indicate this.

[0026] The working principle of this embodiment is as follows: First, the three through holes on the trailer 602 are respectively installed on the tractor with bolts. When the tractor moves, the wheels 105 roll on the ground, driving the ditching plow 102 to open the ditch. The soil covering plate 104 covers and smooths the soil on the rear side. The torsion spring on the rotating shaft 7011 elastically drives the swing arm 701 to generate downward pressure. The wall-adhesive spring 703 squeezes the wall-adhesive cover 704 to fit the V-groove in real time. The lifting and pressing connecting shaft 401 fills the seed box 201 with seeds. Under the pull of the tension spring 402, the lower pressure plate 403 presses down on the seeds. At the same time, as the lower pressure plate 403 presses down, the push plate 404 moves up under the seed stop, driving the seed shortage switch 405 to press the lower pressure plate 403. When manually filling seeds, the switch can be used to control the process. Electromagnet 406 magnetically attracts the push plate 404, ensuring the seed shortage switch 405 presses the lower pressure plate 403. Driven by drive motor 301, the drive disc 302 reciprocates at a uniform speed. Anti-accidental contact torsion spring 3011 provides elastic connection. During normal seed discharge, resistance is low, driving the sowing wheel 202 to rotate. Seeds are discharged using the grooves on the sowing wheel 202, achieving sowing. During this process, the tractor drives this structure to move at a uniform speed, achieving equidistant sowing. If seeds exceeding the size limit are scraped from the grooves on the sowing wheel 202, or if sand or gravel impurities cause the sowing wheel 202 to become stuck on the inner wall of the seed box 201 during rotation, the anti-accidental contact torsion spring 3011 will be twisted. At this time, the output shaft of drive motor 301 is in an idle state, and protrusion 303... Driven by the output shaft of the driven motor 301, the end of the latching switch 304 is pressed against the groove of the latching drive disc 302. At this time, the latching switch 304 can control the drive motor 301 to stop first. Subsequently, if the seed stock is low, the bottom of the seed box 201 has a sloping structure. When the pressure plate 403 stops moving down, there is still a gap between it and the sowing wheel 202. At this time, the seeds no longer stop the push plate 404. With the help of the spring on the push plate 404, the switch 405 is no longer pressed, which can control the disconnection electromagnet 504 to electromagnetically attract the positioning pin 502, stretch the limit spring 503, and pull it out from the plug-in post 601, realizing the separation of the plug-in post 601 and the connecting sleeve 501. The seed box 201 will be left on the ground to avoid being hit by... As the tractor continues to move, the subsequent driver reverses the tractor, causing the plug-in pin 601 to re-insert into the connecting sleeve 501 for connection. Similarly, when the locking switch 304 on the rear side is squeezed, causing seed jamming, the disconnection electromagnet 504 can be controlled to electromagnetically attract the positioning pin 502 to perform disconnection work, preventing continuous movement and ineffective sowing. Once the V-groove collapses, soil will fall into the V-groove. When soil accumulates at the bottom of the V-groove, the wall cover 704 rolls and adheres to the bottom of the V-groove, which can drive the swing arm 701 to move upward, approaching and squeezing the micro switch 106. The micro switch 106 will also control the indicator light 107 to light up, making it easy for the driver to observe in the rearview mirror and indicating that V-groove maintenance work is needed, eliminating the need for tedious manual measurement.
