Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, in particular to a planting mechanism that integrates hole drilling and seedling planting. Background Art

[0002] Transplanting refers to the operation of transplanting seedlings in the seedbed to the field. Its purpose is to allow the transplanted plants to obtain more sufficient nutrients and more growth space, thereby promoting the future development of the plants. The main steps of transplanting include digging holes and planting seedlings. Digging holes of appropriate size and accurately planting seedlings are crucial factors affecting transplanting. Therefore, it is extremely important to efficiently combine the two operations of digging holes and planting seedlings and implement them accurately and smoothly.

[0003] Specific structures used for transplanting in the prior art include chain clamp transplanter planting mechanisms, hanging cup transplanter planting mechanisms, flexible disc transplanter planting mechanisms, seedling guide tube transplanter planting mechanisms, and duckbill transplanter planting mechanisms.

[0004] Currently, the planting mechanism of chain-clamp transplanters relies on a chain as a rotating mechanism, resulting in a slow transplanting rate and easy seedling damage. The planting mechanism of hanging cup transplanters can easily lead to excessive soil cover on the film, resulting in seedling burial. The planting mechanism of flexible disc transplanters has poor adaptability to different soil types and unstable planting depth. The planting mechanism of seedling guide tube transplanters is complex and expensive. The planting mechanism of duckbill transplanters operates in clay soil environments and is prone to duckbill clogging. Therefore, the transplanting mechanisms in existing technologies have problems such as complex structures, high transplanting costs, poor planting results, and easy clogging of the planting mechanism. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to propose an integrated planting mechanism for drilling holes and planting seedlings, so as to solve the problem in the prior art that there is no planting mechanism that can simultaneously achieve coaxial and precise completion of drilling holes and planting seedlings and prevent the overall structure from being blocked with a simple structure, resulting in complicated transplanting operations, high costs, poor planting effects and easy blocking of the planting structure.

[0032] like Figure 1 -7 shows an embodiment of the present invention: a planting mechanism with integrated hole drilling and seedling planting, comprising a load-bearing fixed frame 1, a hole-drilling brushless motor 2 fixedly arranged at the upper end of the load-bearing fixed frame, a motor output hole 3 opened on the upper end surface of the load-bearing fixed frame, a rotating bearing 4 fixedly arranged inside the motor output hole, a transmission shaft 5 provided at the output end of the hole-drilling brushless motor, the transmission shaft passes through the rotating bearing and is clamped and fixedly connected with the rotating bearing, the transmission shaft passes through the motor output hole directly to the lower end of the load-bearing fixed frame, and a transmission gear 6 is fixedly connected to the lower end of the transmission shaft.

[0033] A rotating punching structure is connected to the transmission gear, and the rotating punching structure includes a rotating wheel 7, a punching transmission gear 8, a punching side wall 9 and a punching oblique side wall 10. A rotating wheel is rotatably arranged in the middle position of the lower end of the load-bearing fixed frame. The rotating wheel is divided into an inner ring and an outer ring. The inner and outer rings are driven to rotate by the balls therebetween. The inner ring is fixed on the load-bearing fixed frame, and the outer ring is rotatably arranged on the outside of the inner ring. A punching transmission gear is fixed on the outside of the outer ring, and a punching side wall is fixed at the bottom of the punching transmission gear. The punching side wall and the punching transmission gear are coaxially arranged. The punching side wall consists of three punching side wall blocks 11, and the punching side wall block is a 120° columnar structure. A punching oblique side wall is rotatably connected with a rotating block at the bottom of the punching side wall. The punching oblique side wall consists of three punching oblique side wall blocks 12, and the punching oblique side wall block is a 120° cone structure. The transmission gear is meshed with the punching transmission gear. The operation of the punching brushless motor can drive the transmission gear to rotate, thereby driving the punching transmission gear to rotate, and indirectly driving the punching side wall and the punching oblique side wall to rotate, thereby performing rotational punching.

[0034] A seedling throwing hole 13 is provided at the upper end of the load-bearing fixed frame at a position coaxial with the rotating wheel, a seedling throwing brushless motor 14 is fixedly provided at the upper end of the load-bearing fixed frame, a duckbill seedling throwing device 15 coaxial with the rotating punching structure is provided inside the rotating punching structure through the seedling throwing hole, the duckbill seedling throwing device is connected to the seedling throwing brushless motor through a crank slider structure 16, and a seedling throwing opening structure 17 for opening the top of the rotating punching structure to allow the seedlings to be planted to pass through is fixedly provided inside the rotating punching structure, and the seedling throwing opening structure includes a reset spring fixing plate 18, a reset spring 19, and a reset spring The fixed block 20, the inclined side wall reset rod 21, the rotating block 22 and the duckbill extrusion plate 23, the reset spring fixed plate is fixedly set on the top of the hole side wall, and the rotating block is fixedly set at the connection between the hole side wall and the hole inclined side wall, the hole side wall and the hole inclined side wall are rotatably connected by the rotating block, and the rotating block and the reset spring fixed plate are fixedly connected through the inclined side wall reset rod, and the inclined side wall reset rod is provided with a reset spring and a reset spring fixed block, the duckbill extrusion plate is fixedly set on the inner side of the hole inclined side wall, and the duckbill extrusion plate cooperates with the duckbill seedling thrower.

[0035] Two side ears 24 for opening the duckbill seedling thrower are fixedly provided on the outside of the duckbill seedling thrower, and support bearings 25 corresponding to the side ears are fixedly provided on the upper end of the load-bearing fixed frame. The side ears at both ends of the duckbill seedling thrower are in contact with the support bearings in the duckbill openers on both sides. Because the side ears have a certain inclination angle, the reaction force of the support bearings will gradually increase, and the duckbill will open to drop the seedlings.

[0036] The seedling throwing hole and the duckbill seedling throwing device are coaxially arranged, the seedling spreading and dropping structure and the duckbill seedling throwing device are coaxially arranged, and the seedling spreading and dropping structure and the rotating hole-making structure are coaxially arranged.

[0037] In this embodiment, the punching brushless motor is first started, and the output end of the motor will drive the transmission shaft to rotate. When the transmission shaft passes through the output hole of the motor, it is connected to a rotating bearing, so it can rotate smoothly and unaffectedly, and output its rotation to the transmission gear at the lower end to drive the transmission gear to rotate. Since there is a height difference of 1mm between the inner ring and the outer ring of the rotating wheel, and the inner ring of the rotating wheel is fixed to the load-bearing fixed frame, the outer ring is connected to the punching transmission gear, and the transmission gear and the punching transmission gear are meshed, the transmission gear will drive the punching transmission gear to rotate due to its own rotation. Since the lower end of the punching transmission gear is fixed with a punching side wall, and the lower end of the punching side wall is rotatably provided with a punching oblique side wall through the rotating block, the rotation of the punching transmission gear will drive the punching side wall and the punching oblique side wall to rotate together, and then the whole device is sunk a certain distance, and the rotating structure will complete the punching operation.

[0038] Then the brushless motor for seedling casting is started, and the brushless motor for seedling casting drives the duckbill seedling caster to move down through the seedling casting hole through the crank slider structure to cast the seedlings. When it moves into the inclined side wall of the hole, the duckbill seedling caster moves downward and contacts the duckbill extrusion plate, and generates a gradually increasing extrusion pressure on the duckbill extrusion plate, thereby forcing the duckbill extrusion plate to successfully open; the duckbill extrusion plate will drive the inclined side wall of the hole to open outward, thereby opening a hole for seedling casting in the inclined side wall of the hole, and then the side ears at both ends of the duckbill seedling caster contact with the support bearings on both sides. Since the side ears have a certain inclination angle, as the duckbill seedling caster sinks, the side ears will gradually increase under the reaction force of the support bearings, the duckbill opens, and the seedlings in the hole tray fall into the newly dug hole, completing the seedling casting.

[0039] Then move the whole device up and away from the seedlings in the hole tray, and move the duckbill seedling thrower up. At this time, due to the loss of extrusion force, the inclined side walls of the holes gather and reset under the action of the reset spring, and the extrusion force of the side ears on the support bearings is gradually lost, so the duckbill also gradually closes. During this process, the rotating punching structure is still rotating, so that the soil attached to the outside can be thrown off to avoid blockage. When the duckbill seedling thrower returns to the position before sinking, the duckbill is completely closed, completing the overall operation of drilling holes and dropping seedlings.

[0040] The duckbill seedling dispenser is driven by a brushless motor. The crank-slider mechanism ensures vertical reciprocating motion and periodic opening and closing of the duckbill seedling dispenser, thereby achieving repeated periodic seedling delivery.

[0041] This embodiment proposes an integrated planting mechanism for seedling placement using a simple structure that simultaneously achieves coaxial, precise seedling placement and overall anti-clogging. By combining and linking the seedling placement and seedling placement mechanisms, the mechanism facilitates precise seedling placement at the seedling placement site. By locating the seedling placement mechanism outside the duckbill seedling placement mechanism, duckbill clogging is avoided and the uprightness of the seedlings is significantly improved. The placement of seedling placement within the same structure prevents seedling leakage. The simplified structure and reduced size facilitate simplified operation, improved efficiency, and reduced costs. In this embodiment, seedling placement and seedling placement are performed simultaneously during the transplanting process within the same space, significantly improving the seedling placement rate in the seedling tray. This effectively prevents seedlings from being missed or reseeded. Drilling and seedling placement can be completed in the same step, eliminating the need for dedicated steps, thereby improving overall transplanting efficiency. Furthermore, the seedling placement mechanism utilizes three identical 120° conical sidewalls in the seedling placement mechanism. During opening and closing, the mechanism exerts an outward force on the seedling placement wall and surrounding soil, effectively preventing seedling burial.

[0042] In this embodiment, the surface of the rotating drilling structure is sprayed with an anti-rust coating, which is beneficial to protecting the device from rust.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
