Description

Technical Field

[0001] The present invention relates to the technical field of seeders, and specifically to a multifunctional wheat seeder capable of adjusting the planting spacing of wheat. Background Technique

[0002] A seeder is a modern agricultural machine that greatly improves the efficiency and accuracy of crop planting. Through a preset seeding system, this machine can evenly and quickly spread seeds into the soil, suitable for farmland operations of various scales. Seeders are usually equipped with key components such as a power drive device, a seed storage box, a seeding device, and an adjustment mechanism. Wheat is an important food crop, widely used in food production and industrial raw materials. In agricultural production, the seeding link of wheat is crucial, and a wheat seeder is the key tool to achieve efficient and precise seeding.

[0003] To ensure an even light distribution among wheat plants, a reasonable planting spacing is particularly important. Such a spacing can ensure that each wheat plant can receive sufficient sunlight, thereby effectively improving the efficiency of photosynthesis, which is crucial for promoting the healthy growth of the plants. However, it should be noted that different varieties of wheat have different requirements for planting spacing. Currently, the seeders on the market often lack sufficient flexibility, and they are unable to adjust the corresponding planting spacing according to different wheat varieties, and are unable to adjust the spacing either in the front-back or left-right direction. Therefore, a multifunctional wheat seeder capable of adjusting the planting spacing of wheat is proposed. Summary of the Invention

A through hole is provided on the side wall of the protective housing. The output end of the driving motor extends into the protective housing through the through hole. A coupling is provided at the output end of the driving motor, and the driving shaft is fixedly mounted at the output end of the driving motor through the coupling.

[0012] Preferably, the adjusting mechanism includes an adjusting plate slidably mounted on the equipment frame and a sliding block slidably mounted in the moving chute.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this application, the first transmission shaft has the function of driving the material distributing disc to rotate. During the rotation of the material distributing disc, the wheat seeds on the baffle are pushed down. The pushed-down wheat seeds then enter the metal pipe along the corrugated hose and are finally transported to the planting grooves on the ground through the metal pipe, thus realizing the automatic sowing of wheat. In addition, by adjusting the rotation speed of the material distributing disc, the falling interval of the wheat seeds can be accurately controlled, and further the front and rear spacing of wheat planting can be adjusted.

[0016] 2. During the rotation of the second transmission shaft in this application, it drives the driving gear to rotate accordingly, and then promotes the lifting rack to perform a lifting action. The lifting action of the lifting rack causes the adjusting plate to move up and down, so that the sliding block moves along the activity chute. At the same time, the sliding support feet slide in the distance adjusting chute on the adjusting plate to realize the adjustment of the distance between the metal pipes on the sliding block, thereby adjusting the left and right spacing of wheat planting.

[0017] 3. After the driving motor is started in this application, it drives the driving shaft to rotate. Subsequently, the rotation of the driving shaft is sequentially transmitted to the first linkage shaft and the first transmission shaft, and then the operation of the sowing mechanism is driven. At the same time, by controlling the clutch to be in the engaged state, the rotation of the driving shaft can be further transmitted to the second linkage shaft, and then through the meshing of the worm and the worm wheel, the second transmission shaft is driven to rotate, and the rotation of the second transmission shaft will drive the adjustment mechanism to operate.

Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figure 1 and Figure 2 shown, the present invention provides a technical solution for a multifunctional wheat seeder capable of adjusting the planting spacing of wheat, including a storage box body 2, a sealing box cover 1 is rotatably installed at the upper end of the storage box body 2, an equipment rack body 3 is fixedly installed below the storage box body 2, a movable chute 4 is opened on the equipment rack body 3, a sowing mechanism 5 is fixedly installed at the bottom of the storage box body 2, a driving mechanism 6 is fixedly installed on one side of the mechanism housing 501, an adjusting mechanism 7 is arranged inside the equipment rack body 3. The sowing mechanism 5 can realize the automatic sowing of wheat, and can adjust the front and rear spacing of wheat planting. At the same time, the adjusting mechanism 7 can adjust the left and right spacing of wheat planting.

[0022] As Figure 1 and Figure 3As shown in the figure, the seeding mechanism 5 includes a mechanism housing 501 fixedly installed at the bottom of the storage box 2. A material distributing disk 503 is rotatably installed inside the mechanism housing 501. A material blocking piece 507 is rotatably installed below the material distributing disk 503. An inlet 502 is opened at the upper end of the mechanism housing 501, and an outlet 508 is opened at the lower end of the mechanism housing 501. A corrugated hose 505 is connected inside the outlet 508. A metal pipe 506 is fixedly installed at the lower end of the corrugated hose 505. A first transmission shaft 504 is fixedly installed on the material distributing disk 503. A positioning shaft is provided inside the mechanism housing 501, and the material blocking piece 507 is rotatably installed inside the mechanism housing 501 through the positioning shaft.

[0023] Specifically, the first transmission shaft 504 can drive the material distributing disk 503 to rotate. As the material distributing disk 503 rotates, it will contact the material blocking piece 507, and there are wheat seeds ready for sowing on the material blocking piece 507. During the rotation of the material distributing disk 503, the wheat seeds on the material blocking piece 507 will be pushed down. These wheat seeds will then slide down along the corrugated hose 505 into the metal pipe 506, and then the metal pipe 506 will transport the wheat seeds into the planting grooves on the ground, realizing the automatic sowing of wheat. In addition, by adjusting the rotation speed of the material distributing disk 503, the falling interval of the wheat seeds can be accurately controlled, thereby adjusting the front and rear spacing of wheat planting.

[0024] As Figure 1 and Figure 4 As shown in the figure, the driving mechanism 6 includes a protective housing 601 fixedly installed on one side of the equipment frame 3. A driving motor 604 is fixedly installed on the side wall of the protective housing 601. A driving shaft 603 is fixedly installed at the output end of the driving motor 604. A first linkage shaft 602 is rotatably installed above the driving shaft 603. A second linkage shaft 605 is rotatably installed below the driving shaft 603. A clutch 606 is provided on the second linkage shaft 605. A worm 608 is fixedly installed at the lower end of the second linkage shaft 605. A worm gear 607 is rotatably installed on one side of the worm 608. Helical gears 609 are provided on the first transmission shaft 504, the first linkage shaft 602, the driving shaft 603 and the second linkage shaft 605, and the helical gears 609 are engaged with each other in pairs. A cage is provided inside the protective housing 601, and the first linkage shaft 602, the driving shaft 603 and the second linkage shaft 605 are all rotatably installed inside the protective housing 601 through the cage.

[0025] Specifically, when the drive motor 604 is started, it will begin to rotate the drive shaft 603. As the drive shaft 603 rotates, it will further drive the first linkage shaft 602 to also start rotating. The rotational movement of the first linkage shaft 602 will be transmitted to the first transmission shaft 504, causing it to start rotating as well. The rotation of the first transmission shaft 504 will cause the seeding mechanism 5 to start operating. At the same time, it can be ensured that the clutch 606 remains in the engaged state, so that the rotational power of the drive shaft 603 can be transmitted to the second linkage shaft 605. The rotation of the second linkage shaft 605 will drive the worm 608 to start rotating, and the rotation of the worm 608 will cause the worm gear 607 to rotate accordingly. The rotational movement of the worm gear 607 will be further transmitted to the second transmission shaft 701, thereby driving the operation of the adjustment mechanism 7. The linked operation of the seeding mechanism 5 and the adjustment mechanism 7 is achieved.

[0026] As Figure 5 , Figure 6 , Figure 7 and Figure 8 shown, the adjustment mechanism 7 includes an adjustment plate 703 slidably mounted on the equipment frame 3 and a sliding block 705 slidably mounted in the movable chute 4. A distance adjustment chute 704 is provided on the surface of the adjustment plate 703. A positioning port 706 is provided on the sliding block 705. A sliding support leg 707 is fixedly mounted on the sliding block 705, and the sliding support leg 707 is slidably mounted in the distance adjustment chute 704. A rack base 708 is fixedly mounted on the inner wall of the equipment frame 3. A lifting rack 702 is slidably mounted in the rack base 708, and the lower end of the lifting rack 702 is fixedly mounted on the adjustment plate 703. A drive gear 709 is rotatably mounted on one side of the lifting rack 702. A second transmission shaft 701 is fixedly mounted on the drive gear 709. Bearings are provided on the second transmission shaft 701, and the second transmission shaft 701 is rotatably mounted on the equipment frame 3 through the bearings.

[0027] Specifically, the rotation of the second transmission shaft 701 will drive the drive gear 709 to rotate accordingly. As the drive gear 709 rotates, it will further cause the lifting rack 702 to perform a lifting motion. During the process of the lifting rack 702 performing the lifting action, it will cause the adjustment plate 703 to move up and down. The up and down movement of the adjustment plate 703 will cause the sliding block 705 to slide along the movable chute 4. At the same time, the sliding support leg 707 will also slide in the distance adjustment chute 704 on the adjustment plate 703. This series of actions ultimately realizes the precise adjustment of the distance between the metal pipes 506 on the sliding block 705. Furthermore, the left and right spacing of wheat planting is adjusted.

[0028] Working principle: During use, the entire device is installed on a tractor. After starting the drive motor 604, it drives the drive shaft 603 to rotate. After the drive shaft 603 rotates, it drives the first linkage shaft 602 to rotate. After the first linkage shaft 602 rotates, it drives the first transmission shaft 504 to rotate. After the first transmission shaft 504 rotates, it drives the seeding mechanism 5 to operate. And the clutch 606 can be controlled to be in the engaged state. When the clutch 606 is in the engaged state, the drive shaft 603 can drive the second linkage shaft 605 to rotate. After the second linkage shaft 605 rotates, it drives the worm 608 to rotate. After the worm 608 rotates, it drives the worm wheel 607 to rotate. After the worm wheel 607 rotates, it drives the second transmission shaft 701 to rotate, thereby controlling the adjustment mechanism 7 to operate. When the tractor drives the entire device forward, the wheat seeds in the storage box 2 will fall onto the baffle 507 in the mechanism housing 501. And the first transmission shaft 504 can drive the feeding disk 503 to rotate. During the rotation of the feeding disk 503, the wheat seeds on the baffle 507 will be pushed down. The pushed-down wheat seeds will enter the metal pipe 506 along the corrugated hose 505. The wheat seeds entering the metal pipe 506 will ultimately be transported to the planting grooves on the ground, realizing the automatic seeding of wheat. And by adjusting the rotation speed of the feeding disk 503, the falling interval of the wheat seeds can be adjusted, thereby adjusting the front and rear spacing of wheat planting. When the second transmission shaft 701 rotates, it drives the drive gear 709 to rotate. After the drive gear 709 rotates, it drives the lifting rack 702 to perform a lifting action. When the lifting rack 702 performs a lifting action, it drives the adjustment plate 703 to move up and down. When the adjustment plate 703 moves up and down, the sliding block 705 will slide along the movable chute 4, and the sliding support foot 707 will slide along the distance adjustment chute 704 on the adjustment plate 703, thereby adjusting the distance between the metal pipes 506 on the sliding block 705, and further adjusting the left and right spacing of wheat planting.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
