Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a wheat planter. Background Technology

[0002] A wheat seeder is a specialized machine that sows wheat seeds into the soil at preset row spacing, depth, and density, and is usually used in conjunction with a tractor. Most existing wheat seeders combine the functions of furrowing, sowing, and covering with soil, greatly reducing the workload of farmers in sowing operations.

[0003] However, traditional wheat planters typically only push the soil from both sides of the furrows back into the furrows during the covering process, failing to fully compact the soil. This results in some seeds not being able to make sufficient contact with the soil, affecting seed growth. Compacting the soil requires additional work, reducing farming efficiency. Utility Model Content

[0004] This utility model provides a wheat planter that solves the problems in the background art mentioned above, namely:

[0005] Traditional wheat planters have difficulty compacting the soil in the furrows during the covering process, resulting in some seeds not being able to make full contact with the soil. Compacting the soil also requires additional work, reducing farming efficiency.

[0006] To achieve the above objectives, the wheat planter includes a main mounting frame, with movable wheels rotatably connected to both sides of the main mounting frame. A sowing mechanism is provided on one side of the main mounting frame, and two symmetrically distributed furrowing discs are provided between the two movable wheels. A secondary mounting frame is rotatably connected to the side of the main mounting frame away from the sowing mechanism.

[0007] A soil-pressing mechanism is provided on one side of the auxiliary mounting frame. The soil-pressing mechanism is used to refill the soil turned over by the furrowing pan into the furrows opened by the furrowing pan after sowing and to flatten the soil in the furrows. The soil-pressing mechanism includes two symmetrically distributed soil-pressing wheels, the center lines of the two soil-pressing wheels and the center lines of the two furrowing pans are located on the same plane. A limit groove is opened through the top surface of the auxiliary mounting frame. The soil-pressing mechanism also includes an adjusting rod that is installed through the limit groove. A spring is provided between the adjusting rod and the main mounting frame.

[0008] In the above technical solution, the soil compaction wheel refills the soil turned over by the trenching pan into the trench and compacts it simultaneously, ensuring that the seeds are in full contact with the soil and avoiding the impact of loose soil on the germination rate. In addition, the design of the adjusting rod and spring with the limiting groove can flexibly adjust the angle of the secondary mounting frame, thereby changing the compaction strength of the soil compaction wheel on the soil.

[0009] Based on this, an angle adjustment component is provided on one side of the compaction wheel. The angle adjustment component is used to change the angle of the compaction wheel so that the compaction wheel fits against the sidewall of the trench with different widths. The angle adjustment component includes a connector, and two connectors are symmetrically arranged on both sides of the auxiliary mounting frame. One side of the connector is rotatably connected to the compaction wheel, and one end of the connector is threaded with an adjusting bolt. One end of the adjusting bolt is located on the outside of the connector, and one end of the adjusting bolt and one side of the connector are fixedly connected with several meshing teeth.

[0010] In this technical solution, the angle adjustment component further enhances the adaptability of the soil compaction mechanism. Through the cooperation of the connector and the adjusting bolt, the component enables precise adjustment of the soil compaction wheel angle, so that its sidewall fits tightly into the trenches of different widths. After adjustment, the adjusting bolt and the meshing teeth on the connector engage with each other to form a mechanical lock, ensuring that the soil compaction wheel angle is stable during operation.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. In this wheat planting seeder, the soil turned over by the furrowing plate is refilled into the furrows and compacted simultaneously by the soil compaction wheel in the soil compaction mechanism, ensuring full contact between the seeds and the soil and avoiding the impact of loose soil on the germination rate; in addition, the design of the adjusting rod and spring with the limit groove can flexibly adjust the angle of the secondary mounting frame, thereby changing the compaction strength of the soil compaction wheel on the soil, significantly improving the soil covering effect and reducing the need for subsequent additional compaction processes, thus improving the tillage efficiency.

[0013] 2. In this wheat planting seeder, the angle adjustment component further enhances the adaptability of the soil compaction mechanism. This component, through the cooperation of the connector and the adjusting bolt, enables precise adjustment of the soil compaction wheel angle, so that its sidewalls fit tightly against the trenches of different widths. After adjustment, the adjusting bolt and the meshing teeth on the connector engage with each other to form a mechanical lock, ensuring that the soil compaction wheel angle is stable during operation and ensuring uniform and reliable soil compaction effect under various trench widths.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Currently, traditional wheat planters struggle to compact the soil in the furrows during the covering process, resulting in some seeds not making sufficient contact with the soil. Furthermore, compacting the soil requires additional work, reducing farming efficiency. This invention provides a wheat planter, see [link to relevant documentation]. Figure 1 and Figure 2 As shown, the system includes a main mounting frame 1, with rotatable wheels 2 rotatably connected to both sides of the main mounting frame 1. A sowing mechanism 3 is provided on one side of the main mounting frame 1, and two symmetrically distributed furrowing discs 4 are provided between the two rotatable wheels 2. A secondary mounting frame 5 is rotatably connected to the side of the main mounting frame 1 away from the sowing mechanism 3. During sowing, the main mounting frame 1 is connected to external mobile equipment such as tractors or hoists to move between fields. The sowing mechanism 3 includes at least a seed box and a sowing tube, with the sowing tube positioned between the two furrowing discs 4.

[0028] The auxiliary mounting frame 5 is equipped with a soil pressing mechanism 6 on one side. The soil pressing mechanism 6 is used to refill the soil turned over by the furrowing pan 4 into the furrows opened by the furrowing pan 4 after sowing and to flatten the soil in the furrows. The soil pressing mechanism 6 includes two symmetrically distributed soil pressing wheels 63, the center lines of the two soil pressing wheels 63 and the center lines of the two furrowing pans 4 are on the same plane. A limit groove 51 is opened through the top surface of the auxiliary mounting frame 5. The soil pressing mechanism 6 also includes an adjusting rod 61 that is installed through the limit groove 51. A spring 62 is installed between the adjusting rod 61 and the main mounting frame 1.

[0029] For implementation, see Figure 1 and Figure 3 As shown, hooks are provided at both ends of the spring 62. The spring 62 is fixed between the adjusting rod 61 and the main mounting frame 1 by the hooks. Several interleaved branch grooves are opened on the edge of the limiting groove 51. The adjusting rod 61 can move in multiple branch grooves. When the adjusting rod 61 moves into a branch groove, the elastic force of the spring 62 makes the adjusting rod 61 stuck in the branch groove. When the adjusting rod 61 moves, the angle of the auxiliary mounting frame 5 on the main mounting frame 1 will change, thereby changing the angle of the compaction wheel 63, and thus changing the degree of compaction of the soil in the ditch by the compaction wheel 63.

[0030] In addition, an angle adjustment component 64 is provided on one side of the compaction wheel 63. The angle adjustment component 64 is used to change the angle of the compaction wheel 63 so that the compaction wheel 63 fits against the sidewall of the ditch with different widths. The angle adjustment component 64 includes a connector 641. Two connectors 641 are symmetrically arranged on both sides of the auxiliary mounting frame 5. One side of the connector 641 is rotatably connected to the compaction wheel 63. One end of the connector 641 is threadedly connected to an adjusting bolt 642. One end of the adjusting bolt 642 is located on the outside of the connector 641. Several meshing teeth 643 are fixedly connected to one side of the connector 641 at one end of the adjusting bolt 642.

[0031] Among them, see Figure 3 , Figure 4 and Figure 5 As shown, the compactor wheel 63 is connected to the sub-mounting bracket 5 via the connector 641 and the adjusting bolt 642. During installation, the adjusting bolt 642 first slides through the connector 641, and then the threaded surface of the adjusting bolt 642 is threadedly connected to the connector 641. During the threaded connection, the adjusting bolt 642 will rotate continuously, that is, the compactor wheel 63 rotates around the axis of the adjusting bolt 642 via the connector 641. After the adjusting bolt 642 is fully inserted into the connector 641, the meshing teeth 643 of the adjusting bolt 642 will mesh with the meshing teeth 643 on the connector 641, which mechanically locks the angle of the compactor wheel 63. It should be noted that the meshing teeth 643 are made of elastic plastic material to facilitate the user to rotate the adjusting bolt 642.

[0032] The working principle of this device is as follows:

[0033] Before sowing wheat, the user first adjusts the angle of the two compaction wheels 63 according to the operational requirements, so that the compaction wheels 63 can be used for furrows of different widths. The specific operation steps are as follows: First, the user rotates the adjusting bolt 642 to move it back and forth in the thread of the connector 641. When the meshing teeth 643 on the adjusting bolt 642 and the connector 641 are about to mesh with each other, the user manually moves the compaction wheel 63 to adjust its angle until the side wall of the compaction wheel 63 is in contact with the target furrow. The user continues to rotate the adjusting bolt 642 so that the adjusting bolt 642 and the meshing teeth 643 on the connector 641 mesh with each other, forming a mechanical lock to ensure the stability of the working angle. Afterwards, the user moves the adjusting rod 61 to different branch slots of the limiting groove 51 to change the angle of the secondary mounting bracket 5, thereby adjusting the compaction force of the compaction wheel 63 on the soil.

[0034] During the sowing process, the main mounting frame 1 is moved by an external traction device, and the two moving wheels 2 on both sides support the movement. The furrowing plate 4 opens furrows in the soil between the moving wheels 2. The sowing mechanism 3 simultaneously sows the seeds into the furrows. The soil pressing mechanism 6 follows the operation of the sowing mechanism 3. The soil pressing wheel 63 pushes the soil turned over by the furrowing plate 4 back into the furrows and compacts it to ensure that the seeds are in full contact with the soil.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
