Description

Technical Field

[0001] The utility model belongs to the technical field of seed drills, and more specifically, particularly relates to a soybean seed drill for saline-alkali land. Background Art

[0002] The saline-alkali land soybean seeder can greatly improve the soil physical properties of saline-alkali land. The seeder can be combined with water-saving irrigation technology, such as drip irrigation or sprinkler irrigation system, to effectively utilize limited water resources. The improved saline-alkali land can be used to grow salt-alkali tolerant crops, providing farmers with an additional source of income, strengthening the rural economy, and forming an environmentally friendly agricultural economy.

[0003] At present, there are few special machines on the market for integrated saline-alkali land improvement and soybean sowing, and some traditional seeders can hardly directly meet the needs of saline-alkali land improvement and sowing. Traditional fertilizer applicators generally apply fertilizer on the soil surface, which makes it difficult for small-mass crushed straw to directly enter the soil. In addition, the fertilizer boxes of some current seeders are mostly rectangular, cylindrical or trapezoidal in shape, and are made of fiberglass, plastic or thin steel plates. Straw has the characteristic of light weight. When there is too little straw in the fertilizer box, it may not be able to fall naturally by gravity, causing blockage of the fertilizer box port and the discharge port, which in turn causes waste and affects the fertilization effect.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a saline-alkali land soybean planter is provided to achieve a more practical purpose. Utility Model Content

[0029] Example:

[0030] As attached Figure 1 To Attachment Figure 8 As shown:

[0031] The utility model provides a saline-alkali land soybean seeder, comprising a frame 1, a rotary tillage blade 2 is installed on one side of the frame 1, a ridging device 3 is installed on one side of the bottom end of the frame 1 at a position close to the rotary tillage blade 2, a furrow opener 4 is installed on one side of the bottom end of the frame 1 at a position close to the ridging device 3, a shovel-like component 5 is installed at the middle position of the bottom end of the frame 1, a driving component 6 is installed on the other side of the bottom end of the frame 1, a seeding device 7 is installed on the side of the frame 1 away from the rotary tillage blade 2, a seed box 8 is installed on the top of the seeding device 7, a drip irrigation belt laying device 9 is installed on one side of the top end of the seeding device 7, and a fertilizer pushing component 10 is installed on the top end of the frame 1 at a position directly above the shovel-like component 5.

[0032] The fertilizer pushing assembly 10 includes two fertilizer boxes 1001, which are installed at the middle position of the top of the frame 1. A plurality of fertilizer hoppers 1002 are equidistantly installed at the bottom of the fertilizer box 1001. A fertilizer protection plate 1003 is installed in the fertilizer hopper 1002. A first through slot 1004 is provided at the top of the fertilizer protection plate 1003. A fertilizer cleaning brush 1005 is installed on one side of the first through slot 1004. A second through slot 1006 is provided at the bottom of the fertilizer protection plate 1003. A discharge groove wheel 1007 is installed inside the fertilizer hopper 1002 at a position located on the inner side of the fertilizer protection plate 1003. The crushed straw falls from the fertilizer box 1001 into the fertilizer hopper 1002 and enters the groove formed between the discharge groove wheel 1007 and the fertilizer protection plate 1003. The rotation of the discharge groove wheel 1007 drives the crushed straw to rotate. When the crushed straw moves to the position of the second through groove 1006, it enters the straw funnel 501 under the action of gravity and centrifugal force.

[0033] Among them, an intermediate shaft 11 is installed between the two fertilizer boxes 1001, and the intermediate shaft 11 is connected to a plurality of discharge groove wheels 1007, so as to drive the plurality of discharge groove wheels 1007 to rotate together.

[0034] Among them, a motor 12 is installed on one side of one of the two fertilizer boxes 1001, and the output end of the motor 12 is connected to the intermediate shaft 11 through a coupling. The motor 12 drives the intermediate shaft 11 to rotate, and then drives a plurality of discharge groove wheels 1007 to rotate.

[0035] Among them, the shovel-like component 5 includes a plurality of straw funnels 501, which are respectively installed at the top of the frame 1 at a position directly below each fertilizer funnel 1002. A pipe 502 is installed at the bottom end of the straw funnel 501, and a connecting rod 503 is installed at the bottom end of the pipe 502. A conveying trough 504 is penetrated through the top of the connecting rod 503, and the conveying trough 504 is connected with the pipe 502. A shovel tip 505 is installed at the bottom end of the connecting rod 503, and a pair of baffles 506 are installed on both sides of the top of the shovel tip 505. The crushed straw discharged from the fertilizer pushing component 10 enters the pipe 502 through the straw funnel 501, and is then conveyed to the position of the shovel tip 505 through the conveying trough 504. The shovel tip 505 is triangular, and the baffles 506 on both sides can escort the crushed straw to the designated position in the soil smoothly, thereby preventing the crushed straw from being scattered due to its light weight.

[0036] A pair of dredging openings 507 are symmetrically provided at the bottom ends of both sides of the connecting rod 503 to prevent the crushed straw from being blocked at the outlet.

[0037] Among them, the driving component 6 includes a ground wheel 601, a depth limiting wheel 602 and a pressing wheel 603. The ground wheel 601 is installed on the side of the frame 1 away from the rotary tillage blade 2, the depth limiting wheel 602 is installed on the side of the frame 1 away from the rotary tillage blade 2 and close to the ground wheel 601, and the pressing wheel 603 is installed on the side of the frame 1 away from the rotary tillage blade 2 and close to the depth limiting wheel 602, so as to drive the seeder to move and compact the soil after sowing.

[0038] The working principle of this embodiment is as follows: when the soybean planter for saline-alkali land is used for sowing, the staff first connects the planter to a tractor or other carrier and drives the tractor or other carrier to move. During the movement, the rotary tillage blade 2 first loosens the soil compacted on the surface of the saline-alkali land, turns the soil with high salt content in the surface layer to the lower layer and turns the relatively high-quality soil in the lower layer to the surface layer, and then the ridge-forming device 3 ridges the loosened soil into a ridge body, and then the furrow opener 4 opens a furrow with a depth of about 5 cm on the ridge body, and the straw in the shovel-like component 5 is sown into the furrow under the push of the fertilizer pushing component 10, and the seed meter 7 can evenly sow soybean seeds, and then the drip irrigation tape device 9 buries a row of drip irrigation tapes in the soil, and finally the pressing wheel 603 compacts the soil to ensure full contact between the seeds and the soil. The entire machine is composed of a ground wheel 601 transmission, which drives the rotary tillage blade 2 and the seed metering device 7 by chain transmission, wherein the crushed straw falls from the fertilizer box 1001 into the fertilizer hopper 1002 and enters into the groove formed between the discharge groove wheel 1007 and the fertilizer protection plate 1003. The rotation of the discharge groove wheel 1007 will drive the crushed straw to rotate. When the crushed straw moves to the position of the second through groove 1006, it enters into the straw funnel 501 under the action of gravity and centrifugal force. The crushed straw discharged from the fertilizer pushing component 10 enters into the pipeline 502 through the straw funnel 501, and is then transported to the position of the shovel tip 505 through the conveying trough 504. The shovel tip 505 is triangular, and the baffles 506 on both sides can escort the crushed straw to the designated position in the soil smoothly to prevent the crushed straw from being scattered due to its light weight.
