Description

Technical Field

[0001] The present invention belongs to the field of cassava planting, and particularly relates to a real-time cassava cutting on ridges and direct-insertion cassava planter. Background Art

[0002] In the traditional cassava planting mode, cassava stems are first cut into small segments of approximately the same length at the field head, and then carried to the field by workers using containers such as baskets, hampers, and buckets for planting. When performing the cutting operation, the worker places the cassava stem flat on the anvil, holds one end of the cassava stem with one hand, and cuts the seed stem into the required length with a knife in the other hand. This operation mode is time-consuming, laborious, inefficient, with uneven cutting lengths, and the entire planting process is long and costly.

[0003] Therefore, it is necessary to design an automated cassava planter that can achieve efficient planting of cassava. Summary of the Invention

[0004] In order to overcome the deficiencies existing in the prior art, the present invention provides a real-time cassava cutting on ridges and direct-insertion cassava planter. The real-time cassava cutting on ridges and direct-insertion cassava planter can achieve the cutting and planting of cassava stems, thereby greatly improving the planting efficiency of cassava and reducing the planting cost of cassava.

[0029] The present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings, but the implementation modes of the present invention are not limited thereto.

[0030] Refer to Figures 1 - 16 , the ridge real-time cutting and direct seeding cassava planter of the present invention includes a vehicle frame 1, a real-time cassava cutting device 8 arranged on the vehicle frame 1, and a direct seeding device 9 for inserting the cassava stalks cut by the real-time cassava cutting device 8 into the trenches; wherein,

[0031] The real-time cassava cutting device 8 includes a frame arranged on the vehicle frame 1 and a cassava cutting mechanism arranged on the frame. Among them, a feeding funnel 10 is arranged at the upper end of the frame for the cassava cutting mechanism, and a discharging funnel 12 is arranged at the lower end; the cassava stalks to be planted are inserted from the feeding funnel 10; after being cut by the cassava cutting mechanism, they enter the discharging funnel 12;

[0032] The direct seeding device 9 for cassava includes a seed guiding tube 901 arranged on the frame, a seed pressing plate 906 arranged in the seed guiding tube 901, and a direct seeding driving mechanism for driving the seed pressing plate 906 to move vertically. Among them, the feeding port at the upper end of the seed guiding tube 901 is communicated with the discharging port of the discharging funnel 12, and the lower end extends downward; the direct seeding driving mechanism is used to drive the seed pressing plate 906 to move vertically to press the cassava stalks entering the seed guiding tube 901 into the trenches.

[0033] Refer to Figures 1 - 16, the cassava cutting mechanism includes two sets of seed cutting hob groups 801 and a seed cutting driving mechanism for driving the two sets of seed cutting hob groups 801 to rotate in opposite directions. Among them, each set of seed cutting hob groups 801 includes a turntable, a cutting knife arranged on the turntable, and a fixed cylinder; the turntable is rotatably connected to the frame through a rotating shaft; both the cutting knife and the fixed cylinder are in multiple groups, and the multiple groups of cutting knives and multiple groups of fixed cylinders are alternately arranged at equal angles along the circumferential direction of the turntable;

[0034] The seed cutting driving mechanism includes a gear set and a power transmission mechanism. Among them, the gear set includes two sets of meshing transmission gears 11, and the two sets of transmission gears 11 are respectively arranged on the two rotating shafts; the power transmission mechanism is used to transmit power to one of the rotating shafts to drive the rotation of this set of rotating shafts.

[0035] The power is transmitted to one of the rotating shafts through the power transmission mechanism to drive the rotation of this set of rotating shafts, so as to drive the other set of rotating shafts to rotate in the opposite direction through the gear set, and then drive the two sets of seed cutting hob groups 801 to rotate in the opposite direction. When the cutting knives in the two sets of seed cutting hob groups 801 are in contact, the cassava stalks can be cut, so as to cut into the length required for sowing; at the same time, the fixed cylinders in the two sets of seed cutting hob groups 801 can clamp and convey the cassava stalks downward, so that the cassava stalks at the feeding funnel 10 can be continuously moved downward. After the cassava stalks are completely cut, the operator inserts new cassava stalks into the feeding funnel 10 again.

[0036] In this embodiment, the cassava cutting mechanism can be implemented with reference to the "Cassava Seed Cutting Mechanism" in the invention patent application published under the application publication number CN 113170619 A, "A Direct-Planting Cassava Planter".

[0037] See Figures 1 - 16 , the seed pressing plate 906 is connected to the seed guiding tube 901 through a sliding connection structure. The sliding connection structure includes a sliding rail 907 and a slider 908 arranged on the sliding rail 907. Among them, the sliding rail 907 is installed on the seed guiding tube 901 and extends along the axial direction of the seed guiding tube 901; the seed pressing plate 906 includes a rotating part 9062 and pressing plate parts 9061 and driving parts 9063 arranged on both sides of the rotating part 9062. Among them, the pressing plate part 9061 is located inside the seed guiding tube 901; the driving part 9063 is located outside the seed guiding tube 901; the seed guiding tube 901 is provided with an avoidance groove 909 at a position corresponding to the driving part 9063, and the avoidance groove 909 extends along the axial direction of the seed guiding tube 901; the rotating part 9062 is rotatably connected to the slider 908;

[0038] The vertical insertion driving mechanism includes a driving block 905 and a vertical driving mechanism for driving the driving block 905 to move cyclically in the vertical direction. Among them, a tension spring 910 is provided between the driving part 9063 of the seed pressing plate 906 and the bottom of the slide rail 907. The elastic force of the tension spring 910 causes the seed pressing plate 906 to rotate upward, so as to make the plane directions of the pressing plate part 9061 and the driving part 9063 perpendicular to the axial direction of the seed guiding tube 901; the vertical driving mechanism includes a driving synchronous pulley 902, a driven synchronous pulley 904 installed on the frame, and a synchronous belt 903 wound around the driving synchronous pulley 902 and the driven synchronous pulley 904. Among them, the driving synchronous pulley 902 is rotatably connected to the frame through a rotating shaft, and the rotating shaft is connected to one group of rotating shafts through a gear transmission mechanism (for example, gear 13 meshes with one group of transmission gears 11); the driving block 905 is installed on the synchronous belt 903;

[0039] Through the above arrangement, when one of the sets of rotating shafts rotates, the rotating shaft can be driven to rotate through the gear transmission mechanism, thereby driving the active synchronous wheel 902 to rotate, and then driving the synchronous belt 903 to circulate in the vertical direction. While the synchronous belt 903 moves, it also drives the driving block 905 to circulate in the vertical plane; when the synchronous belt 903 drives the driving block 905 to move from bottom to top to the first height position, the top of the driving block 905 contacts the bottom of the driving part 9063 of the seed pressing plate 906; as the driving block 905 continues to move upward, the driving block 905 drives the seed pressing plate 906 to rise while causing the seed pressing plate 906 to gradually rotate from a horizontal state to The seed pressing plate 906 is in a vertical state (i.e., the seed pressing plate 906 rotates 90 degrees downward around the rotation fulcrum to avoid the cassava stems entering the seed guide tube 901); in this process, since the diameter of the active synchronous wheel 902 is larger than the diameter of the driven synchronous wheel 904, when the driving block 905 moves upward, its movement speed is decomposed to obtain two sub-movements, namely, horizontal sub-movement V1 and vertical sub-movement V2; taking the driving block 905 as a reference, the seed pressing plate 906 will also make a horizontal movement V3 while moving upward; therefore, a relative movement will occur between the driving block 905 and the driving part 9063 of the seed pressing plate 906, so that the driving block 905 and the The driving part 9063 of the seed pressing plate 906 gradually overlaps and then gradually staggers; when the synchronous belt 903 drives the driving block 905 to move upward to the second height position, the top of the driving block 905 is completely separated from the bottom of the driving part 9063 of the seed pressing plate 906. At this time, the seed pressing plate 906 is located at the top of the seed guide tube 901 (that is, the top of the cassava stem in the seed guide tube 901). The seed pressing plate 906 rotates from a vertical state to a horizontal state under the tension of the tension spring 910. Since a locking structure is provided between the seed pressing plate 906 and the slider 908, the locking structure is used to limit the rotation of the seed pressing plate 906 around its rotation fulcrum between the horizontal state and the vertical state. Therefore, when the seed pressing plate 906 rotates to a horizontal state, the seed pressing plate 906 stops rotating and moves downward in a horizontal state to a first height position under the tension of the tension spring 910; in this process, the pressing plate part 9061 of the seed pressing plate 906 presses the cassava stems in the seed guide tube 901 into the groove; when the cassava stems are inserted into the groove, since the seed guide tube 901 is provided with an avoidance groove 909 on the opposite side of the moving direction of the on-ridge real-time cutting and direct-insertion cassava planter of the present invention, as the on-ridge real-time cutting and direct-insertion cassava planter of the present invention moves forward, the top of the cassava stem still located in the seed guide tube 901 escapes from the avoidance groove 909.Since the synchronous belt 903 rotates cyclically, the synchronous belt 903 will drive the driving block 905 to return to the first height position again, so as to drive the seed pressing plate 906 located at the first height position to move upward, thereby restarting the seed pressing work.

[0040] In this embodiment, a guide plate 911 for guiding the movement of the driving block 905 is arranged on the frame, and the outer contour of the guide plate 911 is the same as the outer contour of the surrounding direction of the synchronous belt 903.

[0041] See Figures 1 - 16 , the stop structure includes two groups of limit blocks 912. One group of limit blocks 912 is used to limit the seed pressing plate 906 from rotating upward to the vertical state, and the other group of limit blocks 912 is used to limit the seed pressing plate 906 from rotating downward to the horizontal state.

[0042] See Figures 1 - 16 , the cross-section of the seed guiding tube 901 is square, and the seed pressing part of the seed pressing plate 906 is also square.

[0043] See Figures 1 - 16 , a fertilizing device 4 is arranged on the vehicle frame 1. The fertilizing device 4 includes a fertilizer tank 4 and a fertilizer discharging mechanism arranged at the bottom of the fertilizer tank 4; the fertilizer discharging mechanism includes a fertilizer discharging runner and a fertilizer discharging driving mechanism for driving the fertilizer discharging runner to rotate. Among them, the fertilizer discharging driving mechanism includes a first transmission shaft 14 and a fertilizer discharging motor for driving the first transmission shaft 14 to rotate; the fertilizer discharging runner is installed on the first transmission shaft 14; the fertilizer discharging motor drives the first transmission shaft 14 to rotate, thereby driving the fertilizer discharging runner to rotate, so as to discharge the fertilizer in the fertilizer tank 4 and realize the fertilizing work.

[0044] See Figures 1 - 16 , the power transmission mechanism includes a second transmission shaft 16. The second transmission shaft 16 is rotatably connected to the frame, and one end of the second transmission shaft 16 is connected to one group of rotating shafts through a coupling; the second transmission shaft 16 is connected to the first transmission shaft 14 through a first chain transmission mechanism 15; the power of the first transmission shaft 14 is transmitted to the second transmission shaft 16 through the first chain transmission mechanism 15, thereby driving the second transmission shaft 16 to rotate, so as to drive the cassava real-time seed cutting device 8 and the cassava direct planting device 9 to work; at the same time, walking wheels are arranged at the bottom of the vehicle frame 1, and the wheel shafts of the walking wheels are connected to the second transmission shaft 16 through a second chain transmission mechanism 17. While the second transmission shaft 16 rotates, the walking wheels can also be driven to rotate.

[0045] See Figures 1 - 16, a seat 6 and a guardrail 2 are provided on the frame 1 behind the seat 6; a protective partition 5 is provided above the real-time cassava seed cutting device 8, and the protective partition 5 is used to prevent the operator sitting on the seat 6 from accidentally touching the seed cutting hob group 801 or the gear group in the real-time cassava seed cutting device 8, so as to protect the personal safety of the operator as much as possible.

[0046] In this embodiment, there are two groups of the seats 6. Correspondingly, the real-time cassava seed cutting device 8, the direct cassava planting device 9, and the fertilizer discharging ports in the fertilizer application device 4 are all two groups, that is, the ridge real-time seed cutting and direct planting cassava planter of the present invention can simultaneously realize cassava planting in two trenches.

[0047] See Figure 1 , soil covering plates 3 are provided on both sides of the bottom of the frame 1, and the upper ends of the soil covering plates 3 are rotatably connected to the frame 1; after the direct cassava planting device 9 inserts the cassava stalks into the trenches, as the ridge real-time seed cutting and direct planting cassava planter of the present invention continues to move forward, the soil covering plates 3 push the soil on both sides of the trenches into the trenches.

[0048] See Figure 1 , a three-point suspension bracket 7 is provided on the frame 1, and the three-point suspension bracket 7 is connected to a towing vehicle (such as a tractor), and the ridge real-time seed cutting and direct planting cassava planter of the present invention is driven by the towing vehicle to move, so as to complete the cassava planting work.

[0049] See Figures 1 - 16 , the working principle of the ridge real-time seed cutting and direct planting cassava planter of the present invention is as follows:

[0050] Before working, install the ridge real-time seed cutting and direct planting cassava planter of the present invention on a towing vehicle (such as a tractor), and drive the ridge real-time seed cutting and direct planting cassava planter of the present invention by the towing vehicle.

[0051] During working, the operator inserts the cassava stalks into the feeding hopper 10, the power transmission mechanism transmits power to one group of rotating shafts to drive the rotation of this group of rotating shafts, thereby driving the reverse rotation of the other group of rotating shafts through the gear group, and further driving the reverse rotation of the two groups of seed cutting hob groups 801. When the cutters in the two groups of seed cutting hob groups 801 are in contact, the cassava stalks can be cut, so as to cut the cassava stalks into the lengths required for planting; at the same time, the fixed cylinders in the two groups of seed cutting hob groups 801 can clamp and convey the cassava stalks downward, so that the cassava stalks at the feeding hopper 10 can be continuously moved downward. The cut cassava stalks enter the seed guiding tube 901 under the guidance of the lower discharging hopper 12;

[0052] The direct insertion drive mechanism drives the seed pressing plate 906 to move downward, thereby inserting the cassava stalks in the seed guide tube 901 into the grooves. Specifically:

[0053] When one of the sets of rotating shafts rotates, the rotating shaft can be driven to rotate through the gear transmission mechanism, thereby driving the active synchronous wheel 902 to rotate, and then driving the synchronous belt 903 to circulate in the vertical direction. When the synchronous belt 903 moves, it also drives the driving block 905 to circulate in the vertical plane; when the synchronous belt 903 drives the driving block 905 to move from bottom to top to the first height position, the top of the driving block 905 contacts the bottom of the driving part 9063 of the seed pressing plate 906; as the driving block 905 continues to move upward, the driving block 905 drives the seed pressing plate 906 to rise while causing the seed pressing plate 906 to gradually rotate from a horizontal state to a vertical state (i.e. The seed pressing plate 906 rotates downward 90 degrees around the rotating fulcrum to avoid the cassava stems entering the seed guide tube 901); in this process, since the diameter of the active synchronous wheel 902 is larger than the diameter of the driven synchronous wheel 904, when the driving block 905 moves upward, its movement speed is decomposed to obtain two sub-movements, namely horizontal sub-movement V1 and vertical sub-movement V2; taking the driving block 905 as a reference, the seed pressing plate 906 will also make horizontal movement V3 while moving upward; therefore, relative movement will occur between the driving block 905 and the driving part 9063 of the seed pressing plate 906, so that the driving block 905 and the seed pressing plate The driving part 9063 of 906 gradually overlaps and then gradually staggers; when the synchronous belt 903 drives the driving block 905 to move upward to the second height position, the top of the driving block 905 is completely separated from the bottom of the driving part 9063 of the seed pressing plate 906. At this time, the seed pressing plate 906 is located at the top of the seed guide tube 901 (that is, the top of the cassava stem in the seed guide tube 901). The seed pressing plate 906 rotates from a vertical state to a horizontal state under the tension of the tension spring 910. Since a locking structure is provided between the seed pressing plate 906 and the slider 908, the locking structure is used to limit the rotation of the seed pressing plate 906 around its rotation fulcrum between the horizontal state and the vertical state. Rotate, so when the seed pressing plate 906 rotates to a horizontal state, the seed pressing plate 906 stops rotating and moves downward in a horizontal state to a first height position under the tension of the tension spring 910; in this process, the pressing plate part 9061 of the seed pressing plate 906 presses the cassava stems in the seed guide tube 901 into the groove; when the cassava stems are inserted into the groove, since the seed guide tube 901 is provided with an avoidance groove 909 on the opposite side of the moving direction of the on-ridge real-time seed cutting and direct-insertion type cassava planter of the present invention, as the on-ridge real-time seed cutting and direct-insertion type cassava planter of the present invention moves forward, the top of the cassava stem still located in the seed guide tube 901 escapes from the avoidance groove 909.Since the synchronous belt 903 rotates cyclically, the synchronous belt 903 will drive the driving block 905 to return to the first height position again, so as to drive the seed pressing plate 906 located at the first height position to move upward, thereby restarting the seed pressing work.

[0054] After the cassava direct seeding device 9 inserts the cassava stem into the groove, as the ridge real-time seed cutting and direct seeding type cassava planter of the present invention continues to move forward, the soil covering plate 3 will push the soil on both sides of the groove into the groove.

[0055] In the above process, since the fertilizing device 4 is arranged on the vehicle frame 1, the groove can be fertilized first, then cassava can be planted, and finally the soil covering work can be carried out.

[0056] In addition, a ditching device can also be arranged on the ridge real-time seed cutting and direct seeding type cassava planter of the present invention, so that the ditching, fertilizing, cassava planting and soil covering work can be completed in sequence.

[0057] The above is a preferred embodiment of the present invention, but the embodiments of the present invention are not limited by the above content. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
