Description

Technical field:

[0002] The invention relates to the technical field of agricultural sowing, and in particular to an electric-driven eye-wheel seeding device with a low-position seeding function. Background technology:

[0004] Sowing is the most critical link in the seed planting process. The quality of sowing directly affects the growth and yield of crops. As the core and carrier of precision sowing technology, the seed meter is very important to ensure the quality of sowing. At present, my country's seed sowing machinery is divided into two types: mechanical and pneumatic. The basic working principles of mechanical seed meters are similar. They are designed with corresponding types or grooves to accommodate seeds according to the shape and size of seeds, and then the excess seeds are taken out through the seed cleaning process of gravity or mechanical structure to achieve seed separation. It has the advantages of simple overall structure and low cost. However, most of the existing mechanical seed meters are driven by ground wheels. The soft soil in the field will cause the ground wheels to slip, affecting the smooth rotation of the seed disc in the seed meter. When the sowing grain distance needs to be adjusted, the seed disc needs to be replaced to adjust the sowing grain distance. The operation is cumbersome and reduces the sowing efficiency. At the same time, due to The structural limitation of the co-positioned contour wheel of the seeder will result in a certain distance between the seed meter and the seed furrow. Although the seeds discharged by the seed meter can be transported to the seed furrow by the additional seed guide tube to overcome the position deviation of the seeds in the falling process caused by the distance, the seeds are easily collided with the tube wall of the seed guide tube when they fall from the seed tray in the seed meter, which affects the seed falling time and significantly deteriorates the uniformity of the sowing grain distance; and the matching gap between the seed guard plate and the seed tray provided in the existing seed meter is fixed, and the curvature of the seed guard plate is fixed, resulting in the seed meter can only be used for sowing seeds of one particle size. When it is necessary to sow different seeds or seeds of different particle sizes, the seed guard plate needs to be disassembled and replaced so that the matching gap between the seed guard plate and the seed tray meets the seeding requirements of the seeds, and avoids the seeds falling out of the matching gap or being blocked in the matching gap, which is troublesome to operate and reduces work efficiency. Summary of the invention:

[0006] In view of the defects and problems mentioned above, the present invention provides an electrically driven eye-wheel seeding device for low-position seeding, which has a unique structure and is easy to use. It adopts an electrically driven method, and can avoid the unstable transmission phenomenon caused by traditional ground wheel drive. The rotation speed of the seed disc can be adjusted by adjusting the output power of the driving motor, so that the sowing grain distance can be adjusted at any time according to needs, and there is no need to adjust the sowing grain distance by replacing the seed disc. With the mutual cooperation of the seed disc and the low-position seeding wheel, the phenomenon of seeds hitting the wall and bouncing in the traditional seed guide tube is effectively avoided, and the uniformity of sowing is improved. Moreover, by adjusting the seed disc seed guard plate, the fitting gap between the seed disc seed guard plate and the seed disc can meet the sowing requirements of different seeds or seeds of different particle sizes, and the situation in which seeds fall out of the fitting gap or are blocked in the fitting gap is avoided.

The seeding motor is fixed on the outer side of the front housing, and the seeding plate is arranged below the seeding port, and the seeding plate is fixedly mounted on the output shaft of the seeding motor. The driving mechanism includes a driving motor and a driving gear. The driving motor is arranged above the seeding disk, and the driving motor is fixed to the rear housing. The output shaft end of the driving motor passes through the front housing to the gear cover, and a seed cleaning brush is fixedly mounted on the output shaft of the driving motor above the seeding disk, and the driving gear is fixed to the end of the output shaft of the driving motor; the transmission mechanism includes an upper gear and a lower gear arranged in the gear cover, the upper gear is coaxially mounted on the first transmission shaft with the seeding disk, a driven gear is arranged on the inner side of the upper gear, the driven gear is fixedly mounted on the first transmission shaft, and the driven gear is connected to the driving gear through a transmission chain, and the lower gear is coaxially mounted on the second transmission shaft with the low-position seeding wheel, and the lower gear is meshed with the upper gear.

[0008] Furthermore, the seed tray seed protection plate is an arc-shaped structure, and the seed tray seed protection plate is connected and fixed to the inner wall of the rear shell body.

[0009] Furthermore, it also includes a seeding wheel guard plate, which is an arc-shaped structure. The seeding wheel guard plate is arranged in the internal chamber of the rear shell and is located on the left side of the low-position seeding wheel. The seeding wheel guard plate is fixedly connected to the inner wall of the rear shell.

[0010] Furthermore, the upper gear and the lower gear have the same number of teeth and the same diameter.

[0011] Furthermore, the tray is evenly arranged on the outer peripheral side of the low-position seeding wheel in an oblique direction along the circumferential direction.

[0012] Furthermore, the diameter of the driving gear is smaller than the diameter of the driven gear.

[0013] Furthermore, the seed cleaning brush is in contact with the outer peripheral side of the seed tray.

[0014] Furthermore, the width of the seed cleaning brush is the same as the width of the seed tray.

[0015] Beneficial effects of the present invention:

[0016] First, the structure is unique. The rotation of the seed disc is controlled by a driving motor, so that the seed disc in the seeder can rotate smoothly, avoiding the situation where the seed disc rotates unsteadily due to the traditional ground wheel drive, and the sowing grain distance can be adjusted at any time according to needs. The operator can adjust the rotation speed of the seed disc by adjusting the output power of the driving motor, thereby controlling the sowing grain distance of the seeds. It is no longer necessary to adjust the sowing grain distance of the seeds by disassembling and replacing the seed disc, thereby improving the sowing efficiency of the seeder.

[0017] Second, the low-position seeding wheel is located below the seed tray, and the seeds fall into the sockets of the seed tray through the seed discharge port. The seed tray rotates to make the seeds in the sockets fall into the seed supporting grooves of the low-position seeding wheel, and the seeds in the low-position seeding wheel are discharged through the seed discharge port. With the mutual cooperation of the seed tray and the low-position seeding wheel, the phenomenon of seeds hitting the wall and bouncing in the traditional seed guide tube is effectively avoided, which affects the seed falling time, and improves the uniformity of seed sowing distance.

[0018] Third, the seed unloading motor can control the position of the seed unloading plate in the seed meter so that the outer end side of the seed unloading plate fits with the outer peripheral side of the seed disc. Under the blocking action of the seed unloading plate, the seeds enter the seed meter through the seed discharge port and accumulate on the top of the seed unloading plate. When the seed disc rotates, the seeds enter the eye sockets, and the excess seeds in the eye sockets will be cleared out by the seed cleaning brush. And through the cooperation between the seed unloading plate and the seed unloading motor, the seed unloading operation can also be conveniently completed.

[0019] Fourth, the seed disc seed protection plate is composed of a plurality of radial slide plates, and a gate line is arranged inside. The screw rod can be extended and retracted in the limit seat by operating the adjusting nut. When the screw rod is extended, the gate line will be tightened, and the radial slide plate will slide radially inward in the guide sleeve through the sliding rod, and the pressure spring will be compressed, thereby shortening the fitting gap between the seed disc seed protection plate and the seed disc; when the screw rod is contracted, the gate line will be released, and the compressed pressure spring will release the elastic force, which acts on the guide sleeve and the clamping seat respectively, so that the radial slide plate will slide radially outward in the guide sleeve through the sliding rod, thereby expanding the fitting gap between the seed disc seed protection plate and the seed disc. The invention is flexible to use, and the tightening degree of the gate line can be adjusted according to the on-site conditions during use, so that the fitting gap between the seed disc seed protection plate and the seed disc can meet the sowing requirements of different seeds or seeds of different particle sizes, thereby avoiding the situation where seeds fall out of the fitting gap or are blocked in the fitting gap.

[0020] Fifth, with the cooperation of the first groove opened at the rear end of the radial slide plate and the clamping plate fixed at the front end, adjacent radial slide plates can be buckled together, avoiding the situation where gaps exist between adjacent radial slide plates after each radial slide plate slides radially outward, thereby preventing the gaps from causing resistance to seeding and even sometimes jamming the seeds.

Specific implementation method:

[0045] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0046] Embodiment 1: Most of the existing mechanical seeders are driven by ground wheels. The soft soil in the field will cause the ground wheels to slip, thereby affecting the smooth rotation of the seed disc. When the seeding grain distance needs to be adjusted, the seed disc needs to be replaced to adjust the seeding grain distance, which is cumbersome and reduces the seeding efficiency. At the same time, due to the structural limitations of the seeder's co-positioned contouring wheel, there will be a certain distance between the seed meter and the seed furrow. Although the seeds discharged by the seed meter can be transported to the seed furrow by an additional seed guide tube to overcome the position deviation of the seeds in the falling process caused by the distance, when the seeds fall from the seed disc in the seed meter into the seed guide tube, they are prone to collide with the tube wall of the seed guide tube, which affects the seed falling time and significantly deteriorates the uniformity of the seeding grain distance.

[0047] In view of the above problems, this embodiment provides an electric driven eye wheel seed metering device for low-position seeding, such as Figure 1-6As shown, it includes a rear shell 2 and a front shell 3, the rear shell 2 and the front shell 3 are snap-fitted and assembled to form a shell, a seed inlet 1 is provided on the top of the shell, and a seed discharge port 7 is provided on the bottom of the shell, a gear cover 301 is fixed on the outside of the front shell 3, and a mounting hole 5 is provided on the side of the shell; Figure 7 As shown, a first transmission shaft 19 is provided in the housing, and a second transmission shaft 20 is provided below the first transmission shaft 19. One end of the first transmission shaft 19 and the second transmission shaft 20 pass through the front housing 3 to the gear housing 301, as shown in FIG. Fig.11 As shown, a seed disc 10 is fixedly mounted on the first transmission shaft 19, and a plurality of eyelet grooves 17 are evenly arranged on the outer peripheral side of the seed disc 10 in the circumferential direction, and a seed disc seed guard plate 9 is arranged on the right side of the seed disc 10, and the seed disc seed guard plate 9 is arc-shaped, and the seed disc seed guard plate 9 is fixedly connected to the inner wall of the rear shell body 3 by bolts, and the width of the seed disc seed guard plate 9 is the same as that of the seed disc 10, and a low-position seeding wheel 11 is fixedly mounted on the second transmission shaft 20, and the low-position seeding wheel 11 corresponds to the seed disc 10 up and down, and a seeding wheel guard plate 18 is arranged on the left side of the low-position seeding wheel 11, and the seeding wheel guard plate 18 is an arc-shaped structure, and the seeding wheel guard plate 18 is connected to the rear shell body 3 by bolts. The bolts are fixedly connected to the inner wall of the rear shell body 2, and a plurality of trays 12 are evenly arranged along the circumferential direction on the outer peripheral side of the low-position seeding wheel 11, and seed supporting grooves 41 are formed between adjacent trays 12, and the seed supporting grooves 41 cooperate with the eyelet grooves 17. The seed tray 10 rotates to make the seeds in the eyelet grooves 17 fall into the seed supporting grooves 41 of the low-position seeding wheel 11, and the seeds in the low-position seeding wheel 11 are discharged through the seed discharge port 7. With the mutual cooperation of the seed tray 10 and the low-position seeding wheel 11, the phenomenon of seeds hitting the wall and bouncing in the traditional seed guide tube is effectively avoided, which affects the seed falling time, and improves the uniformity of seed sowing particle distance.

[0048] like Figure 4-5 As shown, a seed unloading motor 4 is fixed to the upper outer side of the front shell body 3, and a seed unloading plate 8 is fixedly sleeved on the output shaft of the seed unloading motor 4. The seed unloading motor 4 can control the opening and closing of the seed unloading plate 8. When the seed unloading plate 8 is closed, the outer end side of the seed unloading plate 8 can be fitted with the outer peripheral side of the seed disc 10. Under the blocking effect of the seed unloading plate 8, the seeds enter the seeding device through the seed discharge port and are accumulated above the seed unloading plate 8; when the seed unloading plate 8 is opened, the seeds above the seed unloading plate 8 fall down and are discharged through the seed discharge port 7, so that the seeds can be replaced. Change sowing; a driving motor 6 is provided above the seed disc 10, and the driving motor 6 is fixedly mounted on the outer side of the rear housing 2, and the output shaft of the driving motor 6 passes through the rear housing 2 and the front housing 3 to the gear cover 301; a seed cleaning brush 13 is fixedly mounted on the output shaft of the driving motor 6 above the seed disc 10, and the width of the seed cleaning brush 13 is the same as that of the seed disc 10, and the seed cleaning brush 13 is in contact with the outer peripheral side of the seed disc 10, and when the seed disc 10 rotates, the seed cleaning brush 13 can clean out the excess seeds in the socket groove 17; Figure 8-10As shown, a driving gear 21 is fixedly installed at the end of the output shaft of the driving motor 6, and an upper gear 15 is arranged in a gear housing 301. The upper gear 15 and the seed disc 10 are coaxially fixedly installed on the first transmission shaft 19. A driven gear 22 is provided on the inner side of the upper gear 15. The driven gear 22 is fixedly mounted on the first transmission shaft 19. The diameter of the driven gear 22 is larger than the diameter of the driving gear 21, and the driven gear 22 is connected to the driving gear 21 through a transmission chain 14. The transmission chain 14 is used to transmit the power of the driving motor 6, thereby driving the first transmission shaft 19 to rotate. The lower gear 16 is arranged in the gear housing 301, and the lower gear 16 and the low-position seed wheel 11 are coaxially fixedly installed on the second transmission shaft 20. The lower gear 16 and the upper gear 15 are meshed with each other, and the number of teeth and the diameter of the lower gear 16 are the same as those of the upper gear 15. The rotation of the upper gear 15 drives the lower gear 16 to do meshing movement.

[0049] When sowing, the outer shell in which the rear shell 2 and the front shell 3 are buckled and installed is fixed to the seeder through the mounting hole 5. The seed unloading motor 4 controls the rotation of the seed unloading plate 8 so that the outer end side of the seed unloading plate 8 fits with the outer circumference of the seed disc 10. The seeds enter the seed meter through the seed inlet 1. Under the blocking effect of the seed unloading plate 8, the seeds enter the seed meter through the seed discharge port 1 and accumulate above the seed discharge plate 8. The driving motor 6 drives the seed cleaning brush 13 to rotate, and the active gear 21 drives the transmission chain 14 to drive the seed cleaning brush 13 to rotate. The driven gear 22 makes the seed disc 10 rotate, and the seeds are filled into the socket grooves 17 and rotate with the seed disc 10. When passing through the seed cleaning brush 13, the seed cleaning brush 13 clears out the excess seeds in the socket grooves 17, and the upper gear 15 also starts to rotate under the first transmission shaft 19 coaxially outputted by the seed disc 10, thereby driving the lower gear 16. The upper gear 15 and the lower gear 16 perform meshing motion, and the lower gear 16 rotates to drive the low-position seeding wheel 11, and the seeds in the socket grooves 17 pass through the seed disc seed protection plate 9. The seeds are then delivered to the seeding groove 41 of the low-position seeding wheel 11 by the action of their own weight. The low-position seeding wheel 11 rotates with the seeds. When the seeds rotate to the lower end of the seeding wheel guard plate 18, the seeds are delivered to the seeding groove by the action of their own gravity to complete the seeding. The rotation of the seeding disc 10 is controlled by the driving motor 6, so that the seeding disc 10 in the seeding device can rotate smoothly, avoiding the situation that the seeding disc 10 rotates unsteadily by adopting the traditional ground wheel drive, and the sowing grain distance can be adjusted at any time according to the needs. The operator can adjust the rotation speed of the seeding disc 10 by adjusting the output power of the driving motor 6, thereby controlling the sowing grain distance of the seeds. It is no longer necessary to adjust the sowing grain distance of the seeds by disassembling and replacing the seeding disc 10, thereby improving the sowing efficiency of the seeding device. In addition, under the cooperation between the seeding disc 10 and the low-position seeding wheel 11, the phenomenon of the seeds hitting the wall and bouncing in the traditional seed guide tube is effectively avoided, which affects the situation of the seed falling time, and improves the uniformity of the seed sowing grain distance.

[0051] In this embodiment, the trays 12 are evenly arranged obliquely along the circumferential direction on the outer peripheral side of the low-position seeding wheel 11. Through the oblique arrangement of adjacent trays 12, when seeds fall from the socket grooves 17 into the seed holding grooves 41 of the low-position seeding wheel 11, the obliquely arranged trays 12 can better stabilize the seeds in the seed holding grooves 41 and prevent the seeds from falling into the seed metering device.

Under the cooperation of the gate wire 30 and the limit block 40, the independent radial slide plates 23 can be connected in series. The adjusting nut 32 is operated to make the screw rod 33 extend in the limit seat 31. When the screw rod 33 extends, the gate wire 30 is tightened. Under the limiting action of the limit block 40, each independent radial slide plate 23 slides radially inward in the guide sleeve 25 through the slide rod 28, and the pressure spring 26 is compressed, thereby shortening the matching clearance between the seed disc protection plate 9 and the seed disc 10; the adjusting nut 32 is operated to make The screw rod 33 contracts in the limit seat 31. When the screw rod 33 contracts, the gate wire 30 is released, and the compressed pressure spring 26 releases the elastic force, which acts on the guide sleeve 25 and the holder 24 respectively, so that each independent radial slide plate 23 slides radially outward in the guide sleeve 25 through the slide rod 28, thereby expanding the fitting gap between the seed tray seed guard plate 9 and the seed tray 10.

When in use, the tightening degree of the gate wire 30 can be adjusted according to the on-site conditions, so that the fitting gap between the seed tray seed guard plate 9 and the seed tray 10 meets the sowing requirements of different seeds or seeds of different particle sizes, thereby avoiding the situation where seeds fall out of the fitting gap or are blocked in the fitting gap.
