Description

Technical Field

[0001] The invention relates to the technical field of seed drills, in particular to a contour-profiling integrated seed drill. Background Art

[0002] A seeder is a planting machine that sows crop seeds and is used for sowing a certain type or type of crop. A Chinese utility model patent with publication number CN219876823U discloses a quantitative sowing seeder. Through the quantitative sowing mechanism, when sowing, the groove depth can be adjusted according to the seed sowing depth through the mutual cooperation between the various structures on the moving seat, and the seed output can be controlled through the cooperation of the limiting plate and the toggle plate. After sowing, the soil is covered and flattened by the moving roller to facilitate seed growth, thereby helping to improve the efficiency of sowing, improve the practical performance of the seeder, and make it more convenient for people to use.

[0003] In the related art, in order to meet the needs of large-scale sowing work, a seeder is usually required for sowing. However, the existing seeder has certain defects during use. During the sowing process, the sowing amount and the sowing spacing directly affect the growth effect of crops. In order to improve the sowing effect, it is usually necessary to set a corresponding control mechanism on the seeder to control the sowing amount and the sowing spacing. However, the existing seeder control mechanism cannot synchronously control the sowing amount and spacing, so that it is necessary to set up different numbers of electric drive sources, which not only increases the cost of the seeder, but also reduces the energy-saving and environmental protection performance of the seeder.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] See attached Figure 1-7 A contour-profiling integrated seed drill comprises a mounting beam 1, a walking mechanism 2 and a seeding mechanism 3 are arranged on one side of the mounting beam 1, a transmission shaft 4 is rotatably connected to the top of the mounting beam 1 through a bracket, one end of the transmission shaft 4 is transmission-connected to the seeding mechanism 3 through a transmission assembly 5, and the other end of the transmission shaft 4 is transmission-connected to the walking mechanism 2;

[0036] The sowing mechanism 3 includes a fixed block 31 fixed to one side of the mounting beam 1, and the front and back sides of the fixed block 31 are rotatably connected to four movable blocks 32, and a frame 33 is rotatably connected between one side of the four movable blocks 32, and an elastic telescopic rod 34 is hinged between the frame 33 and the fixed block 31, and a sowing assembly 35 and a height-adjustable furrow opener 36 are respectively arranged at the bottom of the frame 33, and a height-adjustable burying assembly 37 is arranged at one side of the bottom of the frame 33;

[0037] By setting the walking mechanism 2, it is convenient to transmit the driving force of the seeder to the transmission shaft 4, and the rotational force of the transmission shaft 4 can be transmitted to the sowing mechanism 3 through the transmission assembly 5. The sowing assembly 35 in the sowing mechanism 3 forms a quantitative and uniformly spaced sowing operation, and effectively combines the walking drive and the sowing drive of the seeder, which not only reduces the production cost of the seeder, but also improves the energy-saving and environmental protection performance and practicality of the seeder.

[0038] By setting the furrow opener 36, a furrow can be opened on the soil, and the seeds can be buried in real time by the burying component 37, further improving the synchronization of the seeder;

[0039] By using two sets of movable blocks 32, the furrow opener 36 and the burying assembly 37 can move within a certain range to adapt to different working environments, and the elastic telescopic rod 34 connects the movable part with the fixed part. The stability of the device and the continuity of movement are improved, and in order to meet the transmission requirements of the seeder, the transmission assembly 5 is used to provide power for the seeder, and the movement of the furrow opener 36 and the covering wheel 372 is ensured to be unaffected under the condition of stable power. The setting of the elastic telescopic rod 34 can improve the buffering performance of the frame 33, thereby achieving the buffering effect during the furrowing and burying process, and improving the furrowing and burying effect;

[0040] The working parts of the seeder can automatically adjust according to changes in terrain, maintain consistency in sowing depth and row spacing, and improve sowing quality and efficiency. The advantages of the four-bar profiling mechanism are that it can achieve automatic control, reduce vibration, increase the pressure of the furrow opener 36, save seeds, ensure uniform sowing, promote crop growth, and increase yield.

[0041] Refer to the attached Figure 4 The sowing assembly 35 includes a cylindrical sowing frame 351 fixed to the bottom of the frame 33, a feeding port is fixedly connected to one side of the top of the sowing frame 351, a discharge port is fixedly connected to one side of the bottom of the sowing frame 351, a partition sleeve 352 is fixedly connected to the inside of the sowing frame 351, a rotating sleeve 353 is rotatably connected between the partition sleeve 352 and the inside of the sowing frame 351, and a through port connected to the feeding port is opened inside the frame 33;

[0042] The opening makes it easy for the storage bin disposed on the top of the frame 33 to inject seeds into the sowing frame 351, and then the seeds in the sowing frame 351 are discharged through the discharge port to form a sowing operation.

[0043] Refer to the attached Figure 4, a special-shaped ring 354 is fixedly connected to the front of the partition sleeve 352, a plurality of L-shaped fixed clamping claws 355 are fixedly connected to the outer surface of the rotating sleeve 353, a plurality of sliding grooves are opened inside the partition sleeve 352, and a plurality of movable clamping claws 357 are slidably connected to the plurality of sliding grooves through positioning columns 356, the movable clamping claws 357 are slidably connected to the inside of the fixed clamping claws 355, a plurality of positioning columns 356 are extended to the inside of the special-shaped ring 354 through the sliding grooves, and a spring is fixedly connected between the plurality of positioning columns 356 and the rotating sleeve 353;

[0044] The special-shaped ring 354 is composed of a half-circle ring and a half-circle elliptical ring. Figure 4 As shown, through the rotation of the rotating sleeve 353, a plurality of fixed clamps 355, a positioning column 356 and a plurality of movable clamps 357 can be driven to rotate, and the positioning column 356 can be elastically squeezed by the elastic force of the spring itself, so that the positioning column 356 contacts the inner surface of the special-shaped ring 354, and when the positioning column 356 moves along the trajectory of the special-shaped ring 354, when it moves to the position of its half-circle elliptical ring, its positioning column 356 can drive the movable clamp 357 to contract, which not only forms the release of seeds during clamping, but also allows the next round of seed clamping work. When it moves to the position of the half-circle circular ring, the elastic squeezing force of the spring itself is cooperated with the fixed clamp 355 to clamp the seeds, thereby forming a cyclic quantitative sowing work.

[0045] Refer to the attached Figure 5 The furrow opener 36 includes a first telescopic block 361 slidably connected to the bottom of the frame 33, a connecting block 362 is fixedly connected to the bottom of the first telescopic block 361, a furrowing block 363 is fixedly connected to one side of the connecting block 362, and a protective plate 364 is fixedly connected to the front and back of the connecting block 362;

[0046] The provision of the trenching block 363 facilitates trenching on the ground when the seeder is traveling, and the provision of the two protective plates 364 not only prevents the soil on both sides from burying the trench after the trench is opened, but also allows the seeds transported by the sowing component 35 to better enter the interior of the trench, thereby preventing the problem of seed scattering.

[0047] Refer to the attached Figure 3 The burying assembly 37 includes a second telescopic block 371 slidably connected to the other side of the bottom of the frame 33, the bottom of the second telescopic block 371 is rotatably connected to two bowl-type soil covering wheels 372, and the top of the first telescopic block 361 and the top of the second telescopic block 371 are both provided with a first locking member;

[0048] By setting up two bowl-type covering wheels 372, the soil on both sides after furrowing can be gathered to the middle, and then the furrow after sowing can be buried, so that sowing and burying are effectively linked and combined, thereby improving the functionality of the seeder. By setting up the first locking piece, the two height-adjustable bowl-type covering wheels 372 can be locked to ensure their stability after height adjustment.

[0049] See attached Figure 7 The transmission assembly 5 includes a first movable frame 51 and a second movable frame 52, one end of the first movable frame 51 is rotatably connected to one end of the second movable frame 52, a connecting shaft 53 is rotatably connected between the inside of the first movable frame 51 and the second movable frame 52, two first pulleys 54 are fixedly connected to the outer surfaces of the two connecting shafts 53, and the two first pulleys 54 are respectively located inside the first movable frame 51 and the second movable frame 52, one end of the transmission shaft 4 is rotatably connected to the inside of the first movable frame 51, one end of the transmission shaft 4 is fixedly connected to the second pulley 55, and the second pulley 55 is connected to the first pulley 54 located inside the first movable frame 51 through a belt, the inside of the second movable frame 52 is rotatably connected to an output shaft 56, the outer surface of the output shaft 56 is fixedly connected to a third pulley 57, and the third pulley 57 is connected to the first pulley 54 located inside the second movable frame 52 through a belt, one end of the output shaft 56 extends to the outside of the second movable frame 52, and one end of the output shaft 56 is connected to the rotating sleeve 353;

[0050] The output shaft 56 is fixedly connected to the interior of the rotating sleeve 353, so that the rotating sleeve 353 can be driven to rotate by the rotation of the output shaft 56, and finally the sowing work of the sowing assembly 35 is realized;

[0051] The transmission shaft 4 is driven to rotate by the walking mechanism 2, and the first pulley 54 is driven to rotate by the second pulley 55, and then another first pulley 54 is driven to rotate by the connecting shaft 53. Through the rotation of the first pulley 54, the third pulley 57 is driven to rotate by the belt, and the output shaft 56 is indirectly rotated, forming the rotation transmission work of the sowing component 35.

[0052] See attached Figure 6 The walking mechanism 2 includes an L-shaped fixed frame 21 fixed to one side of the mounting beam 1, a stretching block 22 is slidably connected inside the L-shaped fixed frame 21, a connecting frame 23 is fixedly connected to one side of the stretching block 22, a power wheel 24 is rotatably connected to one side of the connecting frame 23, a first transmission wheel 25 is fixedly connected to the axis of the power wheel 24 and the other end of the transmission shaft 4, and the two first transmission wheels 25 are connected through a transmission belt. An adjusting member for tensioning the transmission belt is provided on one side of the L-shaped fixed frame 21, and a second locking member is provided on the top of the stretching block 22;

[0053] Through the contact between the power wheel 24 and the ground, the power wheel 24 can be pulled together with the seeder to move on the ground, and then the two sets of first transmission wheels 25 and the transmission belt can be driven to rotate the transmission shaft 4. Through the rotation of the transmission shaft 4, the sowing mechanism 3 can be driven through the transmission assembly 5 to form an intermittent sowing operation, which effectively combines the walking of the seeder with the sowing drive, thereby improving the energy-saving and environmental protection performance of the seeder;

[0054] The stretching block 22 is connected in a height-adjustable manner, so that the height of the power wheel 24 can be adjusted according to the actual situation. When it rotates, the power is transmitted to the transmission shaft 4 through the belt, and then transmitted to the transmission assembly 5 by the transmission shaft 4; the transmission assembly 5 can move with the movement of the four-link, and will not affect the transmission of power. Finally, the power is transmitted to the seed drill by the transmission assembly 5, so that the movement of the agricultural machine and the seed drill is consistent, ensuring the accuracy of the seeding spacing. And this power transmission method enables the furrow opener 36 and the covering wheel 372 to have a wider floating range, improving the profiling effect.

[0055] Refer to the attached Figure 5 The first locking member has the same structure as the second locking member, including grooves opened on the top of the first telescopic block 361, the second telescopic block 371 and the stretching block 22, and a plurality of card holes opened inside the frame 33 and the L-shaped fixed frame 21, and two T-shaped card blocks are slidably connected inside the groove, and an elastic member is fixedly connected between the two T-shaped card blocks;

[0056] The elastic part is preferably a spring, a metal shrapnel or other rubber elastic material. Through the elastic force of the elastic part itself, the two T-shaped blocks can be elastically squeezed so that the two T-shaped blocks move apart, and then one end of the two T-shaped blocks is inserted into the card holes at the corresponding position to form a lock after height adjustment.

[0057] Embodiment 2: Based on embodiment 1, the difference is that;

[0058] Refer to the attached Figure 6 The adjusting member includes an L-shaped frame 26 fixed to one side of the L-shaped fixed frame 21, an adjusting block 27 is slidably connected inside the L-shaped frame 26, a second transmission wheel 28 is rotatably connected to the side of the adjusting block 27, an outer surface of the second transmission wheel 28 is in contact with the transmission belt, and a screw rod 29 for driving the adjusting block 27 up and down is rotatably connected inside the L-shaped frame 26, and the screw rod 29 is threadedly connected to the inner part of the adjusting block 27;

[0059] By manually rotating the screw rod 29, the adjustment block 27 can be driven to move up and down, and then the second transmission wheel 28 can be driven to move up and down, which not only makes it convenient for the staff to replace the transmission belt, but also makes it convenient to adjust the tension of the transmission belt, so as to improve the smoothness and stability of its rotation transmission.

[0060] Embodiment 3: Based on embodiment 1, the difference is that;

[0061] See attached Figure 8-11 The front of the sowing frame 351 is fixedly connected with a support frame, and the support frame is rotatably connected to the outer surface of the output shaft 56. One end of the output shaft 56 is fixedly connected with a first rotating wheel 6. The interior of the rotating sleeve 353 is fixedly connected with a fixed shaft 7. The outer surface of the fixed shaft 7 is detachably mounted with a second rotating wheel 8. The first rotating wheel 6 and the second rotating wheel 8 are connected by a transmission belt.

[0062] The output shaft 56 can be rotated to drive the first rotating wheel 6 to rotate, and then the second rotating wheel 8 can be driven to rotate through the transmission belt, and then the rotating sleeve 353 can be driven to rotate, so as to form an intermittent sowing operation of the sowing assembly 35. The model of the second rotating wheel 8 can be set to be greater than, less than or equal to the model of the first rotating wheel 6, so that the staff can replace different second rotating wheels 8 according to different sowing needs, thereby realizing sowing operations with different spacings, and improving the functionality and practicality of sowing;

[0063] A limiting groove is provided on the outer surface of the fixed shaft 7, and a limiting strip for inserting into the limiting groove is fixedly connected to the inner surface of the second rotating wheel 8. A locking sleeve 9 is sleeved on one end of the fixed shaft 7, and two locking holes are provided inside the locking sleeve 9, and a locking sleeve is rotatably connected to one side of the locking sleeve 9. A locking groove is provided inside the fixed shaft 7, and two convex clamping plates 10 are slidably connected inside the locking groove. The protruding ends of the two convex clamping plates 10 extend into the two locking holes respectively, and a group of triangular blocks 11 are fixedly connected to the inner side surfaces of the two convex clamping plates 10. A bolt rod 12 is rotatably connected inside the locking groove, and a trapezoidal block 13 is threadedly connected to the outer surface of the bolt rod 12. The two inclined surfaces of the trapezoidal block 13 are respectively slidably connected to the inclined surfaces of the two groups of triangular blocks 11, and one end of the bolt rod 12 extends to the outside of the fixed shaft 7;

[0064] By manually rotating the bolt rod 12, the trapezoidal block 13 can be driven to move forward and backward. By the forward and backward movement of the trapezoidal block 13, the two sets of triangular blocks 11 can be driven in a relative or separated direction through the inclined surfaces on both sides, thereby driving the two convex clamping plates 10 to move in a relative or separated direction.

[0065] By the relative movement of the two convex card plates 10, the protruding ends on the two convex card plates 10 can be driven to move out from the inside of the locking hole, thereby losing the locking of the locking sleeve 9, forming the disassembly of the locking sleeve 9, and then the second rotating wheel 8 can be disassembled and replaced; on the contrary, by the movement of the two convex card plates 10 away from each other, the protruding ends on the convex card plates 10 can be inserted into the locking holes at the corresponding positions, forming the locking of the locking sleeve 9, and then the installation of the second rotating wheel 8 is completed, which has a good disassembly and assembly function, and is convenient for the staff to quickly disassemble and replace the second rotating wheel 8, meeting the replacement of second rotating wheels 8 of different sizes and models, and realizing the work of sowing with different spacings;

[0066] The setting of the tightening sleeve is used to tighten the second rotating wheel 8 sleeved on the outer surface of the fixed shaft 7 to ensure the stability of the second rotating wheel 8 after installation, and the tightening sleeve is connected to the locking sleeve 9 in a rotating manner so that after the second rotating wheel 8 is tightened by the tightening sleeve, the normal rotation of the second rotating wheel 8 is not affected.
