Description

Technical Field

[0001] The invention relates to the technical field of cotton sowing, in particular to a cotton sowing machine. Background Art

[0002] The cotton seeder uses mechanical devices to evenly sow cotton seeds into the soil according to a certain spacing between plants and rows, creating good conditions for the germination and growth of cotton seeds. It can sow cotton seeds in the seed box onto the ground, reducing manual participation and improving sowing efficiency.

[0003] Some existing cotton planters are designed for large-scale intensive planting. This means that when the planter is working, it not only needs the front vehicle to provide power to drive the planter to move, but the mechanical movement required during the sowing process also requires the front vehicle to be driven and controlled by hydraulic means. Under the premise of ensuring economic benefits, the planter is designed to be larger and the configuration requirements of the front vehicle are also very high. For some small-area personal use, the cost is relatively high, so it needs to be improved. Summary of the invention

[0024] 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.

[0025] In one embodiment, see Figure 1-Figure 10 A cotton sowing machine comprises a base 1, wherein the base 1 comprises a flat plate of a U-shaped structure, wherein the middle of the flat plate of the U-shaped structure is a through hole, and extension plates are arranged at the front and rear sides of the flat plate of the U-shaped structure, and bearing seats 31 are arranged at the ends of the extension plates, wherein the bearing seats 31 are rotatably connected to a main shaft 30, and an end of the main shaft 30 away from the center of the base 1 is fixedly connected to a walking wheel 2, and further comprises a sowing mechanism 3 and a driving mechanism 4; The sowing mechanism 3 includes a storage hopper 12 arranged on the side of the base 1 away from the ground. The storage hopper 12 is a conical structure with an opening at the top. The storage hopper 12 is arranged directly above the base 1. A sowing rod 14 is slidably connected to the center position of the bottom of the storage hopper 12. The sowing rod 14 is vertically arranged, and a sowing cavity 20 with an opening at the bottom is arranged at the lower end of the sowing rod 14. A feeding hole 21 is arranged on the side wall of the sowing cavity 20. When the sowing rod 14 moves upward, the feeding hole 21 moves to the inside of the storage hopper 12. At this time, the seeds in the storage hopper 12 will move to the inside of the sowing cavity 20 through the feeding hole 21, and the lower side of the sowing rod 14 is arranged as an inclined surface, so as to facilitate the insertion of the sowing rod 14 into the soil to achieve the sowing effect. A lifting seat 11 is arranged on both the front and rear sides of the upper end of the storage hopper 12, and a front and rear facing screwdriver is rotatably connected to the lifting seat 11. A driving shaft 13 is provided, and a crank 15 is provided in the middle of the driving shaft 13. The middle part of the crank 15 is rotatably connected to the upper end of the transmission plate 16, and the lower end of the transmission plate 16 is rotatably connected to the upper end of the sowing rod 14. Therefore, when the driving shaft 13 rotates, the crank 15 and the transmission plate 16 cooperate to pull the sowing rod 14 up and down. When the sowing rod 14 moves to the top, the feed hole 21 moves to the inside of the storage hopper 12, and the seeds will enter the inside of the sowing cavity 20. When the sowing rod 14 moves downward, the feed hole 21 moves to the bottom of the storage hopper 12. At this time, the seeds will not continue to enter the sowing cavity 20. In addition, since the sowing rod 14 is at the top for a short time, the time after the feed hole 21 moves to the inside of the storage hopper 12 is short, and only a small part of the seeds can enter the inside of the sowing cavity 20, thereby achieving the effect of quantitative sowing; The driving mechanism 4 includes a transmission belt 22 arranged on both sides of the base 1 and rotating synchronously with the walking wheel 2. The two ends of the driving shaft 13 are slidably connected with a sliding sleeve 24 with an adjustable spacing with the lifting seat 11. The outside of the sliding sleeve 24 is fixedly connected with a conical driven wheel 23 that cooperates with the transmission belt 22. The conical driven wheel 23 falls above the transmission belt 22. Therefore, when the transmission belt 22 rotates synchronously with the walking wheel 2, the conical driven wheel 23 will also rotate, thereby realizing the rotation of the driving shaft 13. Therefore, when the entire seeder moves on the ground, the rotation of the walking wheel 2 can be converted into the up and down movement of the sowing rod 14. Therefore, the seeder does not need additional driving equipment, and only needs the front of the vehicle to move the seeder on the ground. Moreover, since the diameters of the conical driven wheel 23 at different positions are different, even if the seeder moves at the same speed, when the transmission belt 22 contacts the conical driven wheel 23 at different positions, the angular velocity of the driving shaft 13 changes, thereby changing the sowing spacing of the seeder.

[0026] In one case of the present embodiment, a sliding support sleeve 8 is vertically arranged on the front and rear sides of the upper surface of the base 1, and a vertically arranged sliding support rod 10 is slidably connected above the sliding support sleeve 8. The upper end of the sliding support rod 10 is fixedly connected to the lower surface of the lifting seat 11, and is rotatably connected to the end of the limiting push rod 9 on the outer side of the sliding support sleeve 8. When the seeder is in normal use, the limiting push rod 9 is in a hanging state under the action of gravity, and the conical driven wheel 23 can fall on the transmission belt 22 for rotation. However, when the lifting seat 11 is lifted, the limiting push rod 9 is rotated to an upward state, and the limiting push rod 9 is an L-shaped structure, so the end of the limiting push rod 9 is a plane that can fit the lower surface of the lifting seat 11. At this time, the lifting seat 11 is lifted, and the conical driven wheel 23 is disengaged from the transmission belt 22. At this time, when the seeder moves on the ground, the sowing rod 14 will not move up and down.

[0027] In one case of the present embodiment, one end of the main shaft 30 close to the center of the base 1 is fixedly connected to a driving pulley 32, and the transmission belt 22 is wrapped around the outside of the driving pulley 32, so that the transmission belt 22 rotates synchronously with the driving pulley 32, and deflection arms 28 are provided on the left and right sides of the driving pulley 32, and the lower ends of the deflection arms 28 are rotatably connected to the side surfaces on the left and right sides of the base 1, and a tensioning pulley 29 is provided at the upper ends of the deflection arms 28, and the transmission belt 22 is wrapped around the outside of the tensioning pulley 29, and the upper ends of the two deflection arms 28 are deflected outwardly, so that the transmission belt 22 is tightened by the tensioning pulley 29, ensuring that the transmission belt 22 rotates synchronously with the driving pulley 32, and when the conical driven pulley 23 does not contact the transmission belt 22, the transmission belt 22 is in a triangular state, and when the conical driven pulley 23 falls, it will press down the upper part of the transmission belt 22. In addition, a tensioning assembly 40 is disposed on the upper surface of the base 1 , and the tensioning assembly 40 can provide power for the deflection arm 28 to rotate outward, so that the transmission belt 22 remains in a tensioned state to transmit power.

[0028] In one case of the present embodiment, the tensioning assembly 40 includes a limit slide bar 36 vertically arranged on the front and rear sides of the upper surface of the base 1, and the upper part of the limit slide bar 36 is slidably connected to the limit slide sleeve 37, and the left and right sides of the limit slide sleeve 37 are rotationally connected to the upper end of the push rod 35, and the lower end of the push rod 35 is rotationally connected to the shift rod 34, and the end of the shift rod 34 is fixedly connected to a slider 33 slidably connected to the deflection arm 28, and a limit plate 39 is fixedly connected to the upper end of the limit slide bar 36, and a buffer spring 38 is arranged between the limit plate 39 and the limit slide sleeve 37 and is sleeved on the outside of the limit slide bar 36. The buffer spring 38 will push the limit slide sleeve 37 downward, so that the push rod 35 pushes the deflection arms 28 on both sides to rotate synchronously and in opposite directions to separate from each other, thereby achieving the effect of keeping the transmission belt 22 tensioned.

[0029] In one case of the present embodiment, the upper end of the lifting seat 11 is slidably connected with a telescopic plate 26 arranged in a front-to-rear direction, and the telescopic plate 26 is an L-shaped structure. The end of the telescopic plate 26 close to the center of the base 1 is a vertical plate, and the end of the telescopic plate 26 away from the center of the base 1 is fixedly connected to the mounting frame 25, and the mounting frame 25 is a U-shaped structure. The two ends of the mounting frame 25 are rotatably connected to the two ends of the sliding sleeve 24, and one end of the adjusting screw rod 27 is rotatably connected to the side of the mounting frame 25 close to the center of the base 1. The middle part of the adjusting screw rod 27 is threadedly connected to the lifting seat 11, and the other end of the adjusting screw rod 27 is rotatably connected to the vertical plate position of the telescopic plate 26. Therefore, when the adjusting screw rod 27 rotates, the telescopic plate 26 will slide back and forth along the lifting seat 11, thereby adjusting the position between the sliding sleeve 24 and the lifting seat 11, that is, changing the contact position between the conical driven wheel 23 and the transmission belt 22, changing the transmission ratio, and changing the sowing spacing.

[0030] In one case of the present embodiment, four rotating seats 17 are arranged on the upper surface of the base 1, and the rotating seats 17 are arranged outside the through hole in the middle of the base 1, and the rotating seats 17 are evenly distributed relative to the center of the storage hopper 12. The rotating seat 17 is rotatably connected to the lower end of the auxiliary support rod 18, and the upper end of the auxiliary support rod 18 is rotatably connected to the auxiliary support wheel 19. The auxiliary support wheel 19 is pressed against the outside of the storage hopper 12, and a reset device is arranged inside the rotating seat 17. The reset device can be a torsion spring. The reset device makes the auxiliary support rod 18 rotate toward the direction of the storage hopper 12, so that the auxiliary support wheel 19 presses the storage hopper 12. By setting four auxiliary support wheels 19 to press the storage hopper 12, the storage hopper 12 can maintain a vertical state and move up and down stably, thereby ensuring stability during sowing.

[0031] In one case of the present embodiment, a connecting seat 6 is provided in the middle of the right side surface of the base 1, and the connecting seat 6 is rotatably connected to the left end of the connecting arm 5. A mounting hole is provided at the right end of the connecting arm 5. When the seeder needs to be connected to the traction machinery, the right end of the connecting arm 5 can be buckled on the connecting part of the traction machinery through the mounting hole, and an auxiliary support rod 7 is provided in the middle of the left side surface of the base 1. When the seeder does not need to work, the entire seeder can be rotated counterclockwise, and the auxiliary support rod 18 will be supported on the ground at this time, so that the entire seeder is stably supported by the auxiliary support rod 7 and the two walking wheels 2, which is convenient for long-term parking. A seeder can work as a single device, but when a large area of ​​land needs to be sown, multiple seeders can work at the same time. At this time, the seeders are arranged from front to back, and a straight connecting frame 41 is taken out. Multiple connecting pins 42 are set from front to back on the upper surface of the connecting frame 41. At this time, the mounting hole at the right end of the connecting arm 5 can be sleeved on the connecting pin, and a connecting head is also set at the right end of the connecting frame 41 to connect the connecting frame 41 with the relevant traction machinery, so that the traction machinery can drive multiple seeders to work at the same time, thereby improving the work efficiency when sowing on a large area. In addition, since the seeder itself does not require additional drive from the traction machinery, it only needs a simple synchronous pulling. If several seeders are needed, just pull them synchronously.

[0032] During the implementation of this embodiment, the seed drill is transferred to the sowing site by means of a transport machine, and is connected to the relevant traction equipment through the mounting hole of the connecting arm 5. At this time, the traction machine only needs to drive the seed drill to move in the field, and no additional control components or hydraulic components are required to drive the internal units of the seed drill to work, so the simplest traction head can be used.

[0033] First, the position of the conical driven wheel 23 is adjusted according to the required sowing spacing, that is, the front and rear positions of the conical driven wheel 23 are changed by adjusting the screw rod 27. After the adjustment is completed, the limit push rod 9 is rotated downward. At this time, the conical walking wheel 2 will fall on the transmission belt 22 under the action of gravity, and the cotton seeds to be sown are poured into the storage hopper 12. The traction head drives the entire seeder to move, and the walking wheel 2 rotates. At this time, the transmission belt 22 drives the drive shaft 13 to rotate through the conical driven wheel 23, so the sowing rod 14 continuously moves back and forth up and down. When the sowing rod 14 moves to the upper side, the seeds inside the storage hopper 12 will enter the sowing cavity 20 through the feed hole 21, and when the sowing rod 14 falls, it will be inserted into the ground. At this time, under the action of inertia, the seeds fall to the ground, and when the sowing rod 14 moves upward again and is pulled out of the soil, the seeds are left in the inserted pit, and the land can be covered with a mulch film later to wait for the seeds to germinate. During the planting process, you can wait until the sowing is completed before fertilizing, and then cover the soil with film after fertilization is completed, or you can mix the seeds and fertilizers together and pour them into the storage hopper 12, so that the seeds and fertilizers will enter the ground at the same time during the sowing process, saving the planting steps.

[0034] The present invention is applicable to a cotton seeder. By arranging a transmission belt 22 and a conical driven wheel 23 on both sides of a base 1, when the seeder moves at a constant speed, the rotation of the walking wheel 2 can be converted into the up and down movement of the sowing rod 14 according to different transmission ratios, so that the seeder can complete the cotton sowing process with adjustable spacing only by relying on the towing of the traction head. The structure of the whole seeder is simple, and only the most basic traction head is needed to work, which reduces the difficulty of use and is suitable for planting in a small area.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
