Description

Technical Field

[0001] This utility model generally relates to the field of agricultural machinery, specifically to the field of sowing equipment, and in particular to a wheat oil seed sowing device. Background Technology

[0002] A wheat and rapeseed seed planter is an agricultural machine used for sowing wheat and rapeseed seeds. The planter is equipped with a seeder that uses a seed delivery tube to transport the seeds to a seed outlet tube, from which the seeds fall into the field. After falling, the seeds are covered with soil by a rotary tiller in front.

[0003] Existing wheat oil seed planting devices may cause unevenness in the field when the seeds fall onto the soil. After the rotary tiller covers the soil, the seed depth may be inconsistent, which affects the seed planting effect. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a wheat oil seed sowing device that ensures the sowing effect.

[0005] In a first aspect, the present invention provides a wheat oil seed sowing device, wherein the wheat oil seed sowing device moves forward in a first direction, and the wheat oil seed sowing device includes a frame, a gearbox, a first pressure roller, a seeder, a second pressure roller, a rotary tiller roller, and a front ground wheel. The gearbox is fixedly connected to the frame and is provided with an output shaft. The seeder is fixedly connected to the frame and is connected to a seed outlet pipe through a seed delivery pipe. The first pressure roller and the front ground wheel are rotatably connected to the frame, the second pressure roller is rotatably connected to the frame, the output shaft provides driving force for the rotation of the second pressure roller, and the seed outlet pipe is located between the second pressure roller and the first pressure roller.

[0006] According to the technical solution provided in the embodiments of this application, a second pressure roller is added in front of the seed outlet tube, and the output shaft provides driving force for the rotation of the second pressure roller. Before the seeds fall from the seed outlet tube to the field, the second pressure roller rotates and compacts the field, so that the flatness of the field remains consistent before the seeds fall. This ensures that the seed depth remains consistent after the rotary tiller covers the seeds that have fallen to the field with soil, thus ensuring the sowing effect of wheat oilseeds.

[0014] Please refer to Figures 1-4 The present invention relates to a wheat oil seed sowing device. The wheat oil seed sowing device moves forward in a first direction 10. The wheat oil seed sowing device includes a frame 100, a gearbox 200, a first pressure roller 300, a seeder, a second pressure roller 500, a rotary tiller roller, and a front ground wheel 600. The gearbox 200 is fixedly connected to the frame 100 and is provided with an output shaft. The seeder is fixedly connected to the frame 100 and is connected to the seed outlet pipe 400 through a seed delivery pipe. The first pressure roller 300 and the front ground wheel 600 are rotatably connected to the frame 100, respectively. The second pressure roller 500 is rotatably connected to the frame 100. The output shaft provides driving force for the rotation of the second pressure roller 500. The seed outlet pipe 400 is located between the second pressure roller 500 and the first pressure roller 300.

[0015] In an embodiment of this utility model, the wheat oil seed sowing device is connected to a tractor. The tractor provides power to the wheat oil seed sowing device and drives it to move along the first direction 10. The first pressure roller 300, the seeder, the second pressure roller 500, the rotary tiller roller, and the front ground wheel 600 are arranged sequentially along the first direction 10. When the tractor drives the wheat seed sowing device, the front ground wheel 600 rolls on the ground, supporting the frame 100; the gearbox 200 drives the rotary tiller roller to rotate, and the rotary tiller blades on the roller till the field, loosening and covering the soil; the gearbox 200 drives the second pressure roller 500 to rotate, and the second pressure roller 500 compacts the field, providing a more level field for seed sowing; the seeder is connected to the seed outlet pipe 400 through the seed delivery pipe, and the seeds flow out from the seed outlet pipe 400 and enter the field, where the rotary tiller roller will carry soil to cover the seeds; the first pressure roller 300 will compact the covered seeds, ensuring close contact between the seeds and the soil, thereby improving the germination rate.

[0016] The gearbox 200 is connected to the tractor, which acts as the power output, causing the output shaft of the gearbox 200 to rotate. The rotary tiller roller is driven by a chain to the output shaft, causing it to rotate. The first pressure roller 300 is also driven by a chain to the output shaft, causing it to rotate. A second pressure roller 500 is added in front of the seed outlet tube 400. The output shaft provides the driving force for the rotation of the second pressure roller 500. Before the seeds fall from the seed outlet tube 400 onto the field, the second pressure roller 500 rotates and compacts the field, ensuring that the field is evenly level before the seeds fall. This guarantees that the seeds are covered with soil by the rotary tiller rollers at a consistent depth, ensuring the sowing effect of wheat and oilseeds.

[0017] Furthermore, the second pressure roller 500 has support end plates 510 rotatably connected to both ends, and the two support end plates 510 are fixedly connected to the frame 100 in an adjustable manner in the vertical direction.

[0018] In this embodiment of the invention, the second pressure roller 500 is rotatably connected to two end plates 510. The support end plates 510 and the second pressure roller 500 are rotatably connected via bearings, ensuring the reliability of the rotation of the second pressure roller 500. The two ends of the second pressure roller 500 are supported by the support end plates 510, ensuring the stability of the rotation of the second pressure roller 500.

[0019] The two support end plates 510 are respectively fixedly connected to the frame 100 in an adjustable manner in the vertical direction. The height of the second pressure roller 500 can be adjusted according to the soil moisture and viscosity to adapt to different sowing environments and achieve the best sowing effect.

[0020] Furthermore, the frame 100 is provided with multiple waist holes 110, the length of which is set in the vertical direction. Multiple bolts 120 pass through the support end plate 510 and the waist holes 110 respectively and are screwed with a first nut.

[0021] In this embodiment of the invention, multiple bolts 120 pass through the support end plate 510 and the waist hole 110 respectively and are screwed with a first nut, thereby fixing the support end plate 510 to the frame 100. When it is necessary to adjust the height of the second pressure roller 500, the position of the first nut in the waist hole 110 can be adjusted to adapt to different sowing environments and achieve the best sowing effect.

[0022] Furthermore, the front ground wheel 600 is rotatably connected to the first rotating member 610, the first rotating member 610 is rotatably connected to the frame 100, the first rotating member 610 is rotatably connected to the first buffer rod 620, the frame 100 is fixedly connected to the support plate 130, the first buffer rod 620 passes through the support plate 130, the first buffer rod 620 is sleeved with the first spring 621 and the second spring 622, the first spring 621 is located between the support plate 130 and the first rotating member 610, the second spring 622 is located on the side of the support plate 130 facing away from the first rotating member 610, the first buffer rod 620 is fixedly connected to the first stop plate 623, the first stop plate 623 is located on the side of the second spring 622 facing away from the support plate 130.

Of course, the first spring 621 is a high-strength spring, providing sufficient support for the first rotating member 610.

[0024] The first buffer rod 620 passes through the support plate 130, and a through hole can be provided on the support plate 130 for the first buffer rod 620 to pass through. Of course, the diameter of the through hole is larger than the diameter of the first buffer rod 620, so that the first buffer rod 620 can move relative to the support plate 130 during the operation of the wheat oil seed sowing device.

[0025] The first buffer rod 620 is fixedly connected to a first stop plate 623, which prevents the second spring 622 from disengaging from the first buffer rod 620. Of course, the first stop plate 623 can be configured to be detachably fixed to the first buffer rod 620, for example, by means of bolts 120, screws, etc., which facilitates the disassembly and assembly of the first buffer rod 620 and reduces the difficulty of maintenance.

[0026] Furthermore, the first buffer rod 620 is sleeved with a second stop plate 624, which is located between the support plate 130 and the second spring 622.

[0027] In an embodiment of this utility model, the second stop plate 624 separates the support plate 130 from the second spring 622, preventing the second spring 622 from directly contacting the support plate 130 and preventing the end of the second spring 622 from entering the through hole on the support plate 130, thus ensuring the stability of the second spring 622.

[0028] Furthermore, the first buffer rod 620 is sleeved with a third stop plate 625 and a fourth stop plate 626. The third stop plate 625 is located between the first spring 621 and the support plate 130, and the fourth stop plate 626 is located between the first spring 621 and the first rotating member 610.

[0029] In an embodiment of this utility model, the third stop plate 625 separates the first spring 621 from the support plate 130, preventing the first spring 621 from directly contacting the support plate 130 and preventing the end of the first spring 621 from entering the through hole on the support plate 130, thus ensuring the stability of the first spring 621.

[0030] The fourth stop plate 626 separates the first spring 621 from the first rotating member 610, preventing the first spring 621 from directly contacting the first rotating member 610 and preventing the end of the first spring 621 from entering the first rotating member 610, thus ensuring the stability of the first spring 621.

[0032] In this embodiment of the invention, the first pressure roller 300 is rotatably connected to the second rotating member 310, which is rotatable relative to the frame 100. The second rotating member 310 is rotatably connected to a second buffer rod 320, on which a third spring 321 and a fourth spring 322 are sleeved. When the tractor drives the wheat seed sowing device for sowing, the first pressure roller 300 rolls on the field. When the first pressure roller 300 contacts different surfaces, the second rotating member 310 rotates relative to the frame 100, causing the third spring 321 and the fourth spring 322 to extend and retract, allowing the first pressure roller 300 to adapt to various sowing environments. Of course, the third spring 321 is a high-strength spring, providing sufficient support for the second rotating member 310.

[0033] The second buffer rod 320 is sleeved with the fifth stop plate 323, and the second buffer rod 320 is screwed with the second nut 327.

[0034] Furthermore, the support frame 140 is rotatably connected to a sleeve, and the second buffer rod 320 passes through the sleeve.

[0035] In this embodiment of the invention, a sleeve is rotatably connected to the support frame 140, and a second buffer rod 320 passes through the sleeve. During the operation of the wheat oil seed sowing device, the second buffer rod 320 slides relative to the sleeve, and the sleeve rotates relative to the support frame 140, allowing the first pressure roller 300 to adapt to various sowing environments. By setting the sleeve, the second buffer rod 320 can be prevented from detaching from the support frame 140, thus improving reliability.

[0036] Furthermore, the second buffer rod 320 is sleeved with a sixth stop plate 324, which is located between the sleeve and the fourth spring 322.

[0037] In an embodiment of this utility model, the sixth stop plate 324 separates the tube sleeve from the fourth spring 322, preventing the fourth spring 322 from directly contacting the tube sleeve and preventing the end of the fourth spring 322 from entering the tube sleeve, thus ensuring the stability of the fourth spring 322.
