Description

Technical Field

[0001] This invention relates to the field of paddy field sowing technology, and in particular to a paddy field direct seeding machine. Background Technology

[0002] Paddy fields: Land within cities, towns, villages, and independent industrial and mining areas with ridges built around them, capable of storing water regularly, and used for planting aquatic crops such as rice. Paddy fields are divided into two categories according to water source conditions: irrigated paddy fields and rain-fed paddy fields. Irrigated paddy fields refer to cultivated land with a guaranteed water source and irrigation facilities, which can be irrigated normally in normal years and used for planting aquatic crops, including irrigated land for crop rotation. Mechanized direct seeding of paddy fields has advantages such as saving labor and costs and high work efficiency, and is currently developing rapidly at home and abroad. Therefore, direct seeding machines are used when sowing in paddy fields. The inventors have discovered that the existing technology has at least the following unresolved problems: 1. Existing paddy field direct seeding machines have fixed seed spacing, which is not convenient to adjust according to different types of seeds and different terrains of paddy fields, thus failing to meet the actual needs of paddy field direct seeding machines and reducing their applicability; 2. Existing paddy field direct seeding machines cannot accurately control the seed sowing amount, nor can they provide timely feedback on the seed quantity, and they also cannot control the seed sowing depth, failing to meet actual sowing needs and affecting the effectiveness of the paddy field direct seeding machine; Therefore, we propose a paddy field direct seeding machine.

Then, under the drive of the two scissor-type adjustment frames, the spacing between several adjustment blocks can be adjusted, so that the sowing spacing of seeds can be flexibly adjusted according to different types of seeds and different terrains of paddy fields, thereby meeting the actual sowing and usage requirements and expanding the scope of application.

[0015] 2. In this invention, by setting up a storage mechanism, the seeds are moved downward by the lower guide and gravity through the storage box. Then, the number of seeds passing through the discharge pipe is controlled by the solenoid valve on the discharge pipe, so as to accurately control the seed sowing amount. In addition, the folded hose structure of the conveying pipe can keep the discharge pipe connected to the sowing pipe, which can enhance the sowing effect of the entire paddy field direct seeding machine. Furthermore, the balance sensor set inside the storage box can provide timely feedback when the number of seeds in the storage box is insufficient.

[0016] 3. In this invention, by setting up a sowing mechanism and a furrowing mechanism, the movement of several adjusting blocks can drive several limiting frames to move together, allowing several sliders to slide and adjust within the limiting frames. This ensures that the spacing between several furrow openers is consistent with the spacing between several adjusting blocks, allowing the paddy field to be furrowed before sowing. Furthermore, the position of the furrowing shovel can be adjusted by retracting the electric push rod, thereby controlling the sowing depth and achieving orderly sowing. This meets actual sowing needs and improves the effectiveness of use. Attached Figure Description

[0029] The trenching mechanism 8 includes a limiting frame 81. Several trenchers 82 are slidably connected between the front and rear frames of the limiting frame 81. The lower front end of each trencher 82 is slidably connected to a limiting frame 83. The limiting frames 83 are fixedly connected to several adjusting blocks 42. A connecting rod 84 is inserted and fixedly connected to the upper front end of each limiting frame 83. The left and right ends of the limiting frame 81 are fixedly connected to the left and right frames of the live broadcast machine frame 1, respectively.

[0030] The furrow opener 82 includes a slider 821. An electric push rod 822 is provided at the middle of the upper end of the slider 821.

The furrowing shovel 825 is set as a V-shaped structure, which can realize the furrowing of paddy fields to realize direct seeding in paddy fields.

[0031] In summary, during use, the entire paddy field direct seeding machine is first installed and fixed on the seeding vehicle through the mounting holes 11 on the mounting frame 10. Then, the sealing cover 7 is rotated to remove it. Seeds can be poured into the storage boxes 51 through the feed hopper 6, filling all the storage boxes 51 with seeds. The seeds move downwards into the discharge pipe 53 under the guidance of the lower part of the storage box 51 and gravity. Then, the seeding spacing in the paddy field can be adjusted according to actual usage needs. The controller 2 controls the driver 32 to start, causing the positive and negative lead screws 33 to drive the two adjusting plates 34 on them to move outwards, so that the moving frames 35 on the two adjusting plates 34 are divided. The two middle adjusting blocks 42 are moved outwards, and then, driven by the two scissor-type adjusting frames 44, several adjusting blocks 42 slide on the two guide rods 41, adjusting the spacing between them. This allows for flexible adjustment of the seed sowing spacing, adapting to different seed types and paddy field terrains, thus meeting actual sowing and usage needs and expanding the applicability of the paddy field direct seeding machine. Simultaneously, the movement of the adjusting blocks 42 causes several limiting frames 83 to move together with several adjusting rods 823, allowing several sliders 821 to move within the limiting frames 83. The sliding adjustment mechanism 1, with several electric push rods 822 sliding and limiting within the guide groove 9, ensures that the spacing between several furrow openers 82 matches the spacing between several adjusting blocks 42. This allows for furrow opening in the paddy field before sowing. The controller 2 activates the electric push rods 822, and their retraction pushes and pulls the adjusting rod 823 to adjust the position of the furrow opener 825. The sliding connection between the limiting frame 83 and the limiting groove 824 improves the stability of the adjusting rod 823 and the furrow opener 825 during movement, thus controlling the sowing depth and achieving orderly sowing, thereby meeting practical requirements. To meet the actual sowing needs, the direct seeding machine for paddy fields has been improved. The ditching shovel 825 first precisely digs furrows in the paddy field, and then the solenoid valve on the discharge pipe 53 is controlled by the controller 2 to control the number of seeds passing through the discharge pipe 53, thus accurately controlling the sowing amount. In addition, the discharge pipe 53 can always be connected to the sowing pipe 43 through the conveying pipe 54, which is set as a folded hose structure, to ensure the delivery of seeds. Furthermore, the balance sensor set inside the storage box 51 can transmit information to the controller 2 in a timely manner when the number of seeds in the storage box 51 is insufficient, which can enhance the sowing effect of the entire direct seeding machine for paddy fields.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
