Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to an intelligent compound seeder suitable for operation on rice stubble high-humidity land. Background Art

[0002] The multi-function seeder is a multi-functional agricultural machine capable of simultaneously completing tasks such as tilling, fertilizing, and sowing in a single operation. By integrating tasks that previously required multiple machines to perform separately, the multi-function seeder significantly improves agricultural production efficiency and reduces operation time and costs. Furthermore, the synergistic coordination of its various functions ensures a precise match between tillage depth, fertilization, and sowing rates, optimizing the crop growth environment and improving sowing quality and crop yields. It is a crucial piece of equipment for large-scale, efficient production in modern agriculture.

[0003] However, high-humidity rice stubble plots, due to their high soil moisture content and residual rice stubble, place higher demands on seeding operations, requiring specialized seeding equipment for efficient and precise seeding. Existing seeders suitable for high-humidity rice stubble plots often use a simple mechanical gate structure to control the seeding rate, relying on manual adjustment of the gate opening and closing. During operation, it is difficult for operators to quickly and accurately adjust the gate according to the actual conditions of the plot and the seeding requirements. This makes it very easy for the gate to open and close improperly, resulting in fluctuating seeding rates, poor seeding uniformity, and uneven distribution of crop growth space and nutrients.

[0042] The feeding member 53 includes a feeding cover 531. When the feeding cover 531 is opened, seeds can be added to the box body 51. The outer wall of the feeding cover 531 is fixedly connected to the top of the box body 51. The bottom of the feeding cover 531 is fixedly connected to a feeding barrel 532. The feeding barrel 532 serves as a channel for seeds to enter the box body 51, guiding the seeds to enter the box body 51 smoothly. A second motor 533 is provided on the top of the feeding cover 531. The second motor 533 provides power to drive the scraper plate 534 to rotate. A plurality of scraper plates 534 are fixedly connected to the output end of the second motor 533. The scraper plate 534 rotates under the drive of the second motor 533 to evenly transport the seeds from the feeding barrel 532 to the discharge port at the bottom of the box body 51, avoiding seed blockage and ensuring the continuity and uniformity of seed transportation.

[0043] The gear adjustment member 55 includes a fixing ring 551, which is threadedly connected to the threaded rod 542 and moves synchronously with the threaded rod 542, driving the extension shaft 552 to move. The inner side of the fixing ring 551 is threadedly connected to the outer side of the threaded rod 542. The outer side of the fixing ring 551 is fixedly connected with the extension shaft 552. The extension shaft 552 connects the fixing ring 551 and the limiting boss 553, and moves under the drive of the fixing ring 551. At the same time, it provides a sliding track for the limiting boss 553. The other end of the extension shaft 552 is slidably connected to the limiting boss 553. Under the action of spring 1 554, the limiting boss 553 can be stuck in the V-shaped groove 555 on the box body 51 to limit the rotation of the threaded rod 542 and determine The sowing amount gear can be separated from the V-shaped groove 555 under the action of the induction reset mechanism 7 to achieve gear adjustment. A spring 554 is provided at the junction of the limiting boss 553 and the extension shaft 552. The spring 554 provides elastic force for the limiting boss 553 so that it can be tightly clamped into the V-shaped groove 555 to ensure the stability of the sowing amount gear. When the gear is adjusted, a reset force is provided to make the limiting boss 553 re-clamped into the appropriate V-shaped groove 555. A plurality of V-shaped grooves 555 are provided on the inner side of the box body 51. The V-shaped grooves 555 cooperate with the limiting boss 553 to determine different sowing amount gears and ensure the accuracy of the sowing amount adjustment. The shape is adapted to the outer shape of the limiting boss 553.

[0044] The drive element 56 includes a third motor 561. This motor 561 serves as a power source, driving the threaded rod 542 through a transmission element 562 to control the opening and closing of the gate 547. The exterior of the third motor 561 is fixedly connected to the inner wall of the control box 6. The output end of the third motor 561 is provided with a transmission element 562 (a synchronous belt and synchronous pulley transmission structure). This transmission element 562 transmits the power from the third motor 561 to the threaded rod 542, enabling it to rotate at a predetermined speed and direction. The other end of the transmission element 562 is located outside the threaded rod 542.

[0045] The inductive reset mechanism 7 includes an electric push rod 701. Under the control of the inductive proximity sensor, the electric push rod 701 extends or retracts the output end, driving the push plate 702 to rotate. The bottom of the electric push rod 701 is fixedly connected to the inside of the control box 6. The input end of the electric push rod 701 is provided with an inductive proximity sensor. The inductive proximity sensor monitors the sowing situation in real time. When the sowing amount deviates from the set value or reaches the set sowing amount, a signal is sent to the electric push rod 701. The output end of the electric push rod 701 is rotatably connected to the push plate 702. The push plate 702 rotates under the drive of the electric push rod 701. The moving plate 703 transmits power, and the two ends of the push plate 702 are fixedly connected with the rotating plate 703. The rotating plate 703 connects the push plate 702 and the sliding plate 705, and transmits the rotation of the push plate 702 to the sliding plate 705. At the same time, the electromagnetic coil 704 on the top can generate magnetic force to control the electric push rod 701 to stop operating. The two sides of the rotating plate 703 are rotatably connected to the top of the control box 6. An electromagnetic coil 704 is provided at one end near the top of the rotating plate 703. The electromagnetic coil 704 generates magnetic force, and cooperates with the inductive proximity sensor on the electric push rod 701 to control the electric push rod 701 to stop operating.

[0046] The induction reset mechanism 7 also includes a sliding plate 705. Under the push of the rotating plate 703, the sliding plate 705 slides on the inner wall of the control box 6, driving the transmission frame 706 to move. The outer side of the sliding plate 705 is slidably connected to the inner wall of the control box 6. One end of the sliding plate 705 contacts the outer side of the bottom of the rotating plate 703. The other end of the sliding plate 705 is fixedly connected to the transmission frame 706. The transmission frame 706 connects the sliding plate 705 and the ejection column 708 to transmit the movement of the sliding plate 705 to the ejection column 708. A spring 707 is provided between the transmission frame 706 and the control box 6. The spring 707 07 provides elastic force for the transmission frame 706. After the electric push rod 701 stops operating, it drives the transmission frame 706 to retract the ejector column 708, so that the induction reset mechanism 7 returns to its initial state. The other end of the transmission frame 706 is fixedly connected to multiple ejector columns 708. Driven by the transmission frame 706, the ejector column 708 slides along the inside of the box body 51, ejects the limit boss 553, and disengages it from the V-shaped groove 555, thereby releasing the restriction on the rotation of the threaded rod 542 and realizing the adjustment of the seeding amount gear. The outer side of the ejector column 708 is slidably connected to the inside of the box body 51 and corresponds to the V-shaped groove 555.

[0047] Working Principle: Before commencing operation, first open feed cover 531 and pour seeds through feed cover 531 into feed barrel 532, where they enter box body 51. Simultaneously, fertilizer is added to housing 41 of fertilizer box 4. Simultaneously, wheels 2 at the bottom of chassis 1 begin driving, moving the entire seeder across the wet, rice-stubble soil. Simultaneously, tillage plate 8 at the bottom of chassis 1 turns the soil, creating a suitable soil environment for seed and fertilizer sowing. Motor 3 561 is then started, which drives threaded rod 542 to rotate via the synchronous belt and synchronous wheel structure in transmission element 562. When the threaded rod 542 rotates, the fixing nut 541 threadedly connected to it remains fixed, so that the threaded rod 542 moves along its own axis. The threaded rod 542 drives the limiting shell 544 to move through the follower ring 543. The limiting shell 544 then drives the gate 547 to rotate around the damping hinge shaft 546 through the L-shaped connecting plate 545, thereby adjusting the opening size of the discharge port at the bottom of the box body 51, thereby controlling the sowing amount and speed.

[0048] The second motor 533 is turned on, and the second motor 533 drives the plurality of scraper plates 534 to rotate. The scraper plates 534 rotate in the feeding cylinder 532, and evenly convey the seeds to the discharge port at the bottom of the box body 51. When the gate 547 is opened, the seeds fall through the discharge port.

[0049] When the threaded rod 542 rotates, the fixed ring 551 and the threaded rod 542 keep moving synchronously, so that the limit boss 553 is stuck in the V-shaped groove 555. At the same time, the motor 3 561 stops working after sensing the resistance, so that the entire threaded rod 542 stops moving, thereby realizing the control of the opening and closing size of the gate 547. In addition, during the sowing process, the inductive proximity sensor monitors the sowing situation in real time. When the sowing amount is detected to deviate from the set value or reach the set sowing amount, a signal is sent to the electric push rod 701. The output end of the electric push rod 701 extends, driving the push plate 702 to rotate, and the push plate 702 rotates through the rotating plate 703. At the same time, when the rotating plate 703 rotates, it pushes the sliding plate 705 to slide on the inner wall of the control box 6. The sliding plate 705 drives the multiple ejector columns 708 to move through the transmission frame 706. The ejection column 708 slides along the inside of the box body 51, ejecting the limit boss 553, so that it disengages from the current V-shaped slot 555, and after the limit boss 553 is released from the limit, the motor three 561 starts again, thereby realizing automatic adjustment of the seeding amount gear. At the same time, the electromagnetic coil 704 on the top of the rotating plate 703 generates magnetic force, thereby stopping the electric push rod 701 through the inductive proximity sensor on the electric push rod 701, thereby driving the transmission frame 706 to retract the ejection column 708 through the elastic force of the spring two 707. After the seeding amount gear adjustment is completed, under the action of the spring one 554, the limit boss 553 is re-engaged in the appropriate V-shaped slot 555, ensuring that the seeding operation continues according to the correct seeding amount.

[0050] Motor 1 (42) is started, which drives one of the gears (43) to rotate. The two gears (43) mesh with each other, which in turn drives the two crushing rollers (44) to rotate relative to each other on the inner wall of the housing (41). The fertilizer is crushed by the crushing rollers (44) and then discharged through multiple discharge pipes (45) at the bottom of the housing (41). Baffles (46) on either side of the discharge pipes (45) serve to guide the fertilizer and control its falling range.

[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
