Description

Technical Field

[0001] The invention relates to a sugarcane planter, in particular to a whole-stalk pre-loading and real-time automatic seed feeding device for the sugarcane planter. Background Art

[0002] Segmented planting is the predominant sugarcane planting method, which can be divided into pre-cutting and real-time cutting. With the continuous development of the sugarcane sugar industry, mechanized sugarcane planting has become an inevitable trend. Real-time sugarcane planting involves real-time segmentation of whole stalks. The cut sugarcane buds have high self-moisture content, low mold contamination, and a high germination rate after entering the soil. Whole-stalk real-time segmentation requires loading, transporting, clamping, and segmenting. Automated continuous operation requires a large workspace, and the installation of mobile planters can lead to large tool size and excessive power consumption. Currently, real-time sugarcane planting using whole-stalk segmentation is only possible with vehicle-mounted, manually performing loading, transporting, clamping, and segmenting operations. For example, the 2CZQ-2 and 2CZ-2 sugarcane planters commonly used in Guangxi pre-place the sugarcane on the planter's frame. The sugarcane is then manually inserted vertically into the feeder. The segmenting rollers then cut the sugarcane into segments for sowing and evenly distribute them in the field. The next step is soil covering. Although the operation continuity is good, the manual labor is large, the level of intelligence is low, and the cost is high, which affects the income of sugarcane farmers. Summary of the Invention

The automatic seed feeding and sowing device can automatically transport whole-stalk sugarcane to the inlet of the cutting mechanism, saving time and labor and effectively improving work efficiency and economic benefits.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A whole-stalk pre-loading and real-time automatic seed feeding device for a sugarcane planter comprises a seeding mechanism for arranging sugarcanes in an orderly manner, a conveying mechanism for conveying the seeding mechanism, and a one-by-one feeding mechanism for feeding whole-stalk sugarcanes one by one to an inlet of a cutting mechanism;

[0009] The working principle of the above-mentioned whole stalk pre-loading and real-time automatic seed feeding device of the sugarcane planter is as follows:

[0010] During operation, the whole sugarcane plant is inserted into the fixed clamping groove of the seeding frame in an upright state, the whole stalk of sugarcane is clamped on the seeding frame by the clamping structure, and the seeding frame filled with sugarcane is placed on the batch conveying mechanism; the seeding frame filled with sugarcane is transported to the horizontal moving channel of the horizontal mounting frame in turn by the batch conveying mechanism and the intermediate transfer mechanism; the seeding frame is intermittently driven to move toward the inlet of the segmentation mechanism by the intermittent toggle mechanism, and when the sugarcane moves to above the inlet of the segmentation mechanism, the clamping effect of the clamping structure is released by the unlocking structure, that is, the sugarcane is released. At this time, the sugarcane falls into the inlet of the segmentation mechanism below under the action of gravity, and then the segmentation mechanism cuts the whole stalk of sugarcane into segments, and finally the sowing work is carried out.

[0011] In a preferred embodiment of the present invention, the seeding mechanism, the conveying mechanism and the one-by-one feeding mechanism are each provided with two groups and are arranged vertically, so that the sugarcane can be conveyed and fed more stably.

[0012] A preferred embodiment of the present invention is that the clamping structure includes a seeding clamp, a clamping seat, and a tensioning spring; the seeding clamp is located in front of the fixed clamping slot, and the seeding clamp is provided with a movable clamping slot that cooperates with the fixed clamping slot; the clamping seat includes a rod-shaped connecting portion and a mounting portion, one end of the rod-shaped connecting portion passes through the seeding frame and is fixedly connected to the seeding clamp, and the other end of the rod-shaped connecting portion is fixedly connected to the mounting portion; the tensioning spring is sleeved on the rod-shaped connecting portion, and the two ends of the tensioning spring respectively abut against the mounting portion and the seeding frame.

With the above structure, the seeding rack is placed on the conveying chucks of the two conveyor belts and transported forward by the conveyor belts. When the seeding rack moves to the end of the conveying channel, the conveying chucks rotate downward along with the conveyor belts, thereby transferring the seeding rack to the intermediate transfer mechanism.

[0018] When the seed rack is in the state of being ready to be transferred, the one-way push block is located below the conveying channel of the seed rack. After the seed rack approaches the one-way push block, it acts on the lower pressure surface of the push block to press the one-way push block downward, and then the seed rack passes over the one-way push block. At this time, the one-way transfer spring drives the one-way push block to reset; the seed rack continues to move forward until it falls from the conveying seat of the conveyor belt to the transfer pallet; then, driven by the transfer drive mechanism, the transfer pallet moves forward and pushes the seed rack to the horizontal mounting frame of the feeding mechanism one by one through the one-way push block.

When in working condition, the transfer support plate and the one-way push block push the seed rack toward the lateral moving channel. After the limit bar of the seed rack approaches the one-way limit block, it acts on the lower pressure surface of the push block to press the one-way limit block downward. Then the seed rack passes over the one-way limit block, and then the one-way limit spring drives the one-way limit block to reset. At this time, the one-way limit block extends into the limit lock groove of the limit bar, and the one-way limit block limits the seed rack to prevent the seed rack from falling from the lateral mounting frame.

[0021] In a preferred embodiment of the present invention, the intermittent toggle mechanism includes a one-way toggle structure, a toggle transmission assembly, and a toggle drive mechanism;

[0022] The one-way toggle structure includes a one-way toggle tooth, a one-way torsion spring and a shift rod; the toggle transmission assembly includes a sliding block, a forward transmission plate, a return transmission fork and a turntable; the moving direction of the sliding block is parallel to the horizontal movement channel of the horizontal mounting frame; the one-way toggle tooth is rotatably connected to the sliding block; the shift rod is fixed on the sliding block; the one-way torsion spring causes the one-way toggle tooth to press on the shift rod; a plurality of toggle grooves cooperating with the one-way toggle teeth are provided on the side of the seeding frame; one end of the forward transmission plate is fixed on the sliding block, and the other end of the forward transmission plate extends to the top of the turntable ; The return transmission fork is rotatably arranged, and the return transmission fork is provided with a first transmission part and a second transmission part, and the first transmission part is provided with a movable transmission groove; the sliding block is provided with a transmission rod located in the movable transmission groove; the turntable is provided with a shift rod, and the axis of the shift rod is parallel to the rotation center of the turntable; when the sliding block slides in the outward stroke, the shift rod acts on the outward stroke transmission plate; when the sliding block slides in the return stroke, the shift rod acts on the second transmission part of the return transmission fork; the outward stroke moving distance of the one-way shift tooth is equal to the spacing between two adjacent fixed clamping grooves on the seeding rack;

Through the above structure, when the seeding frame is transferred to the horizontal mounting frame, the one-way shifting tooth is engaged with the first shifting slot of the seeding frame, and the other end of the outbound transmission plate is located on the rotation path of the shifting rod. Then, the toggle drive mechanism drives the turntable to rotate, and the shifting rod on the turntable drives the outbound transmission plate to move toward the inlet of the segmenting mechanism, while driving the sliding block and the one-way shifting tooth to move synchronously, so that the seeding frame is shifted toward the inlet of the segmenting mechanism by the one-way shifting tooth, so that the corresponding sugarcane is shifted to above the inlet of the segmenting mechanism. At this time, the second transmission part of the return transmission fork rotates along with the transmission rod on the sliding block to the rotation path of the shifting rod. The above is the outbound operation of the one-way shifting tooth. When the sugarcane is moved to the top of the inlet of the cutting mechanism, the turntable continues to rotate, the shifting rod begins to move away from the outward transmission plate, and gradually approaches the second transmission part of the return transmission fork.

[0049] See also Figure 1-11 The working principle of the whole stalk pre-loading and real-time automatic seed feeding device of the sugarcane planter of this embodiment is as follows:

[0050] During operation, the whole stalk of sugarcane is inserted into the fixed clamping groove 1-1 of the seeding frame 1 in an upright state, and the whole stalk of sugarcane is clamped on the seeding frame 1 by the clamping structure, wherein the operation of the clamping structure is: driving the seeding clamp 2 in the direction away from the fixed clamping groove 1-1, so as to expand the gap between the fixed clamping groove 1-1 and the movable clamping groove 2-1, and after placing the sugarcane vertically between the fixed clamping groove 1-1 and the movable clamping groove 2-1, loosening the seeding clamp 2, the sugarcane can be clamped between the fixed clamping groove 1-1 and the movable clamping groove 2-1; according to the above operation, the sugarcanes can be fixed on the seeding frame 1 one by one.

[0051] The seed rack 1 filled with sugarcane is placed on the conveying seat 4 of the two conveyor belts 5 of the batch conveying mechanism, and the conveyor belt 5 conveys the seed rack 1 forward. When the seed rack 1 moves to the end of the conveying channel, the conveying seat 4 rotates downward with the conveyor belt 5. Furthermore, before the transfer, the one-way push block 8 is located below the conveying channel of the seed rack 1. After the seed rack 1 approaches the one-way push block 8, it acts on the lower pressure surface of the push block, pressing the one-way push block 8 downward. Then, the seed rack 1 passes over the one-way push block 8. At this time, the one-way transfer spring drives the one-way push block 8 to reset. The seed rack 1 continues to move forward until it falls from the conveying seat 4 of the conveyor belt 5 onto the transfer tray 7. Then, driven by the transfer drive mechanism, the transfer tray 7 moves forward and pushes the seed rack 1 to the horizontal mounting frame 11 of the feeding mechanism one by one through the one-way push block 8.

[0052] When the seeding frame 1 is transferred to the horizontal mounting frame 11, the one-way shifting tooth 13 is matched in the first shifting groove 1-4 of the seeding frame 1. At this time, the other end of the outward transmission plate 16 is located on the rotation path of the shifting rod 19. Figure 8 Then, the turntable 18 is driven to rotate by the toggle drive mechanism, and the toggle lever 19 on the turntable 18 drives the outward transmission plate 16 to move toward the inlet of the segmentation mechanism, and at the same time drives the sliding block 15 and the one-way toggle gear 13 to move synchronously, so that the seed rack 1 is toggled toward the inlet of the segmentation mechanism by the one-way toggle gear 13, so that the corresponding sugarcane is toggled to the top of the inlet of the segmentation mechanism. At this time, the second transmission part of the return transmission fork 17 rotates along with the transmission rod on the sliding block 15 to the rotation path of the toggle lever 19, as shown in FIG. Figure 9-10 The above is the forward operation of the one-way shifting tooth 13. When the sugarcane is shifted to above the inlet of the segmentation mechanism, the turntable 18 continues to rotate, and the shifting rod 19 begins to move away from the forward transmission plate 16 and gradually approaches the second transmission part of the return transmission fork 17. When the shifting rod 19 acts on the second transmission part of the return transmission fork 17, the entire return transmission fork 17 rotates. At this time, the first transmission part of the return transmission fork 17 drives the sliding block 15 to move back through the transmission rod, and at the same time drives the one-way shifting tooth 13 to reset. The one-way shifting tooth 13 switches from the first shifting slot 1-4 to the second shifting slot 1-4; the above is the return operation of the one-way shifting tooth 13. Figure 11; This completes a dialing cycle.

[0053] When the sugarcane moves to the top of the inlet of the cutting mechanism, the unlocking push block 21 is squeezed into contact with the unlocking boss 3-1 of the corresponding clamp seat 3, driving the clamp seat 3 to move toward the seeding clamp 2, thereby opening the seeding clamp 2. Figure 10 Under the action of gravity, the sugarcane falls into the inlet of the cutting mechanism below, and then the cutting mechanism cuts the whole stalk of sugarcane into segments, and finally the sowing work is carried out.

[0054] The above is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited to the above content. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
