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

[0030] See also Figure 1-Figure 16 The ridge-based real-time seed cutting and direct insertion cassava planting machine of the present invention comprises a frame 1, a cassava real-time seed cutting device 8 arranged on the frame 1, and a cassava direct insertion device 9 for inserting the cassava stems cut by the cassava real-time seed cutting device 8 into the groove; wherein,

[0031] The cassava real-time seed cutting device 8 comprises a frame arranged on a vehicle frame 1 and a cassava cutting mechanism arranged on the frame, wherein the frame is provided with a feeding funnel 10 at the upper end of the cassava cutting mechanism and a discharging funnel 12 at the lower end; the cassava stems to be planted are inserted from the feeding funnel 10 and enter the discharging funnel 12 after being cut by the cassava cutting mechanism;

[0032] The cassava direct insertion device 9 includes a seed guide tube 901 arranged on a frame, a seed pressing plate 906 arranged in the seed guide tube 901, and a direct insertion drive mechanism for driving the seed pressing plate 906 to move vertically, wherein the feed port at the upper end of the seed guide tube 901 is connected to the discharge port of the discharge funnel 12, and the lower end extends downward; the direct insertion drive mechanism is used to drive the seed pressing plate 906 to move vertically so as to press the cassava stems entering the seed guide tube 901 into the groove.

[0033] See also Figure 1-Figure 16The cassava cutting mechanism comprises two groups of seed cutting rollers 801 and a seed cutting driving mechanism for driving the two groups of seed cutting rollers 801 to rotate in opposite directions, wherein each group of seed cutting rollers 801 comprises a rotating disk, a cutting knife arranged on the rotating disk, and a fixed cylinder; the rotating disk is rotatably connected to the frame via a rotating shaft; the cutting knife and the fixed cylinder are multiple groups, and the multiple groups of cutting knifes and the multiple groups of fixed cylinders are alternately arranged at equal angles along the circumferential direction of the rotating disk;

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

[0035] The power is transmitted to one of the groups of rotating shafts through the power transmission mechanism to drive the group of rotating shafts to rotate, thereby driving the other group of rotating shafts to rotate in the opposite direction through the gear group, and then driving the two groups of cutting roller groups 801 to rotate in the opposite direction. When the cutters in the two groups of cutting roller groups 801 are connected, the cassava stems can be cut to the length required for planting; at the same time, the fixed cylinders in the two groups of cutting roller groups 801 can clamp and transport the cassava stems downward, so that the cassava stems at the feeding funnel 10 can be pulled to move downward continuously. When the cassava stems are completely cut, the operator inserts new cassava stems into the feeding funnel 10.

[0036] In this embodiment, the cassava cutting mechanism can be implemented with reference to the “cassava cutting mechanism” in the “a direct insertion type cassava planting machine” disclosed in the invention patent application with application publication number CN 113170619 A.

[0037] See also Figure 1-Figure 16 The seed pressing plate 906 is connected to the seed guide tube 901 through a sliding connection structure, and the sliding connection structure includes a slide rail 907 and a slider 908 arranged on the slide rail 907, wherein the slide rail 907 is installed on the seed guide tube 901 and extends along the axial direction of the seed guide tube 901; the seed pressing plate 906 includes a rotating part 9062 and a pressing plate part 9061 and a driving part 9063 arranged on both sides of the rotating part 9062, wherein the pressing plate part 9061 is located on the inner side of the seed guide tube 901; the driving part 9063 is located on the outer side of the seed guide tube 901; the seed guide 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 guide tube 901; the rotating part 9062 is rotatably connected to the slider 908;

[0038] The direct insertion drive mechanism includes a drive block 905 and a vertical drive mechanism for driving the drive block 905 to cyclically move in the vertical direction, wherein a tension spring 910 is arranged between the drive portion 9063 of the seed pressing plate 906 and the bottom of the slide rail 907, and the elastic force of the tension spring 910 causes the seed pressing plate 906 to rotate upward, so as to cause the plane direction of the pressing plate portion 9061 and the drive portion 9063 to be perpendicular to the axial direction of the seed guide tube 901; the vertical drive mechanism includes an active synchronous wheel 902 mounted on the frame, a driven synchronous wheel 904, and a synchronous belt 903 wrapped around the active synchronous wheel 902 and the driven synchronous wheel 904, wherein the active synchronous wheel 902 is rotatably connected to the frame through a rotating shaft, and the rotating shaft is connected to one of the rotating shafts through a gear transmission mechanism (for example, the gear 13 is meshed with one of the transmission gears 11); the drive 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 in a circular motion, 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 disposed on the frame, and the outer contour of the guide plate 911 is the same as the outer contour of the synchronous belt 903 in the circling direction.

[0041] See also Figure 1-Figure 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 a vertical state, and the other group of limit blocks 912 is used to limit the seed pressing plate 906 from rotating downward to a horizontal state.

[0042] See also Figure 1-Figure 16 The cross section of the seed guide tube 901 is square, and the seed pressing portion of the seed pressing plate 906 is also square.

[0043] See also Figure 1-Figure 16 A fertilizing device 4 is arranged on the frame 1, and the fertilizing device 4 includes a fertilizer box 4 and a fertilizer discharge mechanism arranged at the bottom of the fertilizer box 4; the fertilizer discharge mechanism includes a fertilizer discharge wheel and a fertilizer discharge driving mechanism for driving the fertilizer discharge wheel to rotate, wherein the fertilizer discharge driving mechanism includes a first transmission shaft 14 and a fertilizer discharge motor for driving the first transmission shaft 14 to rotate; the fertilizer discharge wheel is installed on the first transmission shaft 14; the first transmission shaft 14 is driven to rotate by the fertilizer discharge motor, thereby driving the fertilizer discharge wheel to rotate, so as to discharge the fertilizer in the fertilizer box 4 and realize the fertilization work.

[0044] See also Figure 1-Figure 16 The power transmission mechanism includes a second transmission shaft 16, which is connected to the frame, and one end of the second transmission shaft 16 is connected to one of the 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, thereby driving the cassava real-time cutting device 8 and the cassava direct insertion device 9 to work; at the same time, a walking wheel is provided at the bottom of the frame 1, and the wheel axle of the walking wheel is connected to the second transmission shaft 16 through a second chain transmission mechanism 17. When the second transmission shaft 16 rotates, the walking wheel can also be driven to rotate.

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

[0046] In this embodiment, the seats 6 are in two groups, and correspondingly, the cassava real-time cutting device 8, the cassava direct insertion device 9 and the fertilizer discharge port in the fertilizing device 4 are all in two groups, that is, the real-time cutting and direct insertion cassava planter on the ridge of the present invention can simultaneously realize cassava planting in two grooves.

[0047] See also Figure 1 Soil covering plates 3 are arranged 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; when the cassava direct insertion device 9 inserts the cassava stems into the groove, as the ridge real-time cutting and direct insertion cassava planter of the present invention continues to move forward, the soil covering plates 3 pushes the soil on both sides of the groove into the groove.

[0048] See also 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 traction vehicle (such as a tractor). The traction vehicle drives the on-ridge real-time seed cutting and direct-insertion cassava planter of the present invention to move to complete the cassava planting work.

[0049] See also Figure 1-Figure 16 The working principle of the ridge-based real-time seed cutting and direct insertion cassava planting machine of the present invention is:

[0050] Before working, the on-ridge real-time seed cutting and direct-insertion cassava planter of the present invention is installed on a traction vehicle (such as a tractor), and the on-ridge real-time seed cutting and direct-insertion cassava planter of the present invention is driven to move by the traction vehicle.

[0051] During operation, the operator inserts the cassava stems into the feed hopper 10, and the power transmission mechanism transmits power to one of the groups of rotating shafts to drive the group of rotating shafts to rotate, thereby driving the other group of rotating shafts to rotate in the opposite direction through the gear group, and then driving the two groups of seed cutting roller groups 801 to rotate in the opposite direction. When the cutters in the two groups of seed cutting roller groups 801 are connected, the cassava stems can be cut, thereby cutting the cassava stems into the length required for planting; at the same time, the fixed cylinders in the two groups of seed cutting roller groups 801 can clamp the cassava stems and transport them downward, so that the cassava stems at the feed hopper 10 can be pulled to continue to move downward. The cut cassava stems enter the seed guide tube 901 under the guidance of the discharge funnel 12 below;

[0052] The direct insertion drive mechanism drives the seed pressing plate 906 to move downward, thereby inserting the cassava stems in the seed guide tube 901 into the groove, 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 in a circular motion, 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-insertion device 9 inserts the cassava stems into the groove, as the on-ridge real-time seed cutting and direct-insertion cassava planter of the present invention continues to move forward, the covering plate 3 pushes the soil on both sides of the groove into the groove.

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

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

[0057] 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 that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
