Description

Technical Field

[0001] This utility model relates to the field of wheat planting technology, specifically to an intelligent wheat seeding device that precisely controls row and plant spacing. Background Technology

[0002] A wheat seeding device is a mechanical device that plants wheat seeds in the soil using a seeding system. It is primarily driven by a tractor and is suitable for fertilizing and sowing wheat in plains and hilly areas. It features good versatility, wide adaptability, and uniform sowing.

[0003] In existing technologies, wheat seeding requires a seeder to sow the wheat seeds into the soil at a preset depth. A suitable sowing depth helps seeds absorb moisture and nutrients from the soil, while also protecting them from adverse environmental factors such as low temperatures, drought, and strong winds during germination, thus creating favorable conditions for seed germination and seedling growth.

[0004] However, during the seeding process, when sowing in fields of varying widths, the material discharge end is currently fixed on the seeder. This results in a lack of row spacing adjustment function due to the fixed material discharge end, making it difficult to adapt to the diverse row spacing requirements of fields of varying widths and different planting patterns. Therefore, we propose a smart wheat seeding device that precisely controls row and plant spacing. Utility Model Content

[0005] One of the technical problems this application aims to solve is: during sowing, the row spacing of the planting pattern can be adjusted as needed.

[0006] To address the aforementioned technical problems, this application provides an intelligent wheat seeding device for precise control of row and plant spacing, comprising an adjustment mechanism. A limiting mechanism is provided on the outer side of the adjustment mechanism. The adjustment mechanism includes a side plate, one side of which has an inclined groove.

[0008] In some embodiments, a lead screw is provided on the top side of the side plate, and the top side of the side plate is rotatably connected to the bottom end of the lead screw. A cross plate is provided on the outer side of the lead screw, and the outer side of the lead screw is threadedly rotatably connected to the inner wall of the middle end of the cross plate.

[0009] In some embodiments, one end of the horizontal plate is fixedly connected to the inner side of the seeder, the inner side of the seeder is provided with a hopper, one end of the inner side of the seeder is fixedly connected to the hopper, a sub-tube is provided at the bottom of the hopper, and the bottom of the hopper is fixedly connected to the top of the sub-tube.

[0010] In some embodiments, a flow transfer cavity is provided at the bottom end of the sub-tube, and the bottom end of the sub-tube is fixedly connected to the top end of the flow transfer cavity. A mother tube is provided at the bottom end of the flow transfer cavity, and the bottom end of the flow transfer cavity is fixedly connected to one end of the mother tube.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. By rotating the lead screw in the horizontal plate, the side plate will move down from its original position under the driving action. During the downward movement, the linear movement of the inclined groove will cause the laying discs at both ends of the slide rod to move, thereby increasing the distance between them and the middle laying disc. This allows for precise adjustment of the spacing between the laying discs, changing the spacing between the discharge positions of the main tubes corresponding to different laying discs. This, in turn, precisely controls the plant spacing and row spacing of wheat seeds, making the seeding more uniform and reasonable, and ensuring the quality and effect of wheat sowing.

[0026] This type of intelligent wheat seeding device with precise row and plant spacing control is used by installing a hopper 12 on the seeder 11. The bottom of the hopper 12 is connected to a sub-pipe 13 in a through-type connection. The bottom of the sub-pipe 13 is designed with a transfer chamber 14. When the material is in the hopper 12, it flows through the sub-pipe 13 into the transfer chamber 14. In the transfer chamber 14, the material enters the main pipe 15 by its own gravity. The other end of the main pipe 15 is designed inside a laying disc 16. There are three laying discs 16, with the middle one fixed to a sliding rod 111. Each laying disc 16 is connected to a main pipe 15. To allow for adjustment of the spacing between the laying discs 16 as needed, the middle laying disc 16 is not connected to the connecting rod 111. 7 is connected, and the others are fixedly connected to the connecting rod 17.

This allows for precise adjustment of the spacing between the laying discs 16, changing the spacing between the discharge positions of the mother tube 15 corresponding to different laying discs 16. This allows for precise control of the plant spacing and row spacing of wheat seeds, making the seeding more uniform and reasonable, ensuring the quality and effect of wheat sowing, and improving sowing efficiency.

[0027] An arc-shaped groove 112 is provided on the inner wall of the laying tray 16. An inner rod 113 is designed on the inner surface of the arc-shaped groove 112. One end of the inner rod 113 is connected to a guide plate 114. One end of the guide plate 114 is rotatably connected to the inner side of the laying tray 16. Therefore, by adjusting the position of the inner rod 113 in the arc-shaped groove 112, the tilt angle of the guide plate 114 is increased. When the material flows from the main pipe 15 onto the guide plate 114, the flow speed of the material can be controlled when the guide plate 114 is adjustable. This method can precisely control the flow speed of the material according to the actual sowing needs.

[0028] Example 2: Please refer to Figures 1-4 The limiting mechanism 2 includes a fixing belt 21, an inner rod 113 is provided on the inner side of the fixing belt 21, the inner side of the fixing belt 21 contacts the outer side of the inner rod 113, a fixing member 22 is provided on the inner wall of the fixing belt 21, the inner wall of the fixing belt 21 is threadedly connected to the outer side of the fixing member 22, a protruding rod 23 is provided at the top of the fixing member 22, the top of the fixing member 22 is fixedly connected to the bottom side of the protruding rod 23, and the bottom side of one end of the protruding rod 23 is fixedly connected to the top side of the seeder 11.

[0029] A fixing strap 21 is designed on the outside of the inner rod 113. A protruding rod 23 is connected to the top of the fixing strap 21 and is fixed to the seeder 11. When the position of the inner rod 113 is adjusted, a fixing member 22 is designed in the fixing strap 21. By loosening the fixing member 22, the bottom side of the fixing strap 21 is no longer in contact with the side of the fixing strap 21. Then, the bottom side of the fixing strap 21 is moved down from its original position. Then, the fixing member 22 passes through the fixing strap 21 to limit the position and fix the position of the inner rod 113 after adjustment. This allows the operator to flexibly adjust the position of the inner rod 113 according to different sowing conditions and requirements, thereby changing the tilt angle of the guide plate 114 to adapt to different material characteristics, sowing speed, row spacing and plant spacing requirements.

[0030] Please see Figures 1-5 When the material is in the hopper 12, it flows through the sub-pipe 13 into the transfer chamber 14. In the transfer chamber 14, the material enters the main pipe 15 by its own gravity. The other end of the main pipe is designed within the laying discs 16. There are three laying discs 16, with the middle one fixed to the slide rod 111. Each laying disc 16 is connected to the main pipe 15. To allow for adjustment of the spacing between the laying discs 16 as needed, all but the middle laying disc 16 are fixedly connected to the connecting rod 17. The other end of the connecting rod 17 is located in the inclined groove 115 of the side plate 18. By rotating the lead screw 19 in the horizontal plate 110, the side plate 18... Under the action of the drive, it will move down from its original position. During the downward movement, the linear movement of the inclined groove 115 causes the laying discs 16 at both ends of the slide rod 111 to move, thereby increasing the distance between them and the middle laying disc 16. This allows for precise adjustment of the spacing between the laying discs 16. One end of the inner rod 113 is connected to the guide plate 114, and one end of the guide plate 114 is rotatably connected to the inner side of the laying disc 16. Therefore, by adjusting the position of the inner rod 113 in the arc groove 112, the tilt angle of the guide plate 114 is increased. When the material flows from the main pipe 15 onto the guide plate 114, the flow speed of the material can be controlled when the guide plate 114 is adjustable.

[0031] A fixing strap 21 is designed on the outside of the inner rod 113. A protruding rod 23 is connected to the top of the fixing strap 21, and the protruding rod 23 is fixed on the seeder 11. When the position of the inner rod 113 is adjusted, since the fixing strap 21 is designed with a fixing member 22, by loosening the fixing member 22, the bottom side of the fixing strap 21 is no longer in contact with the side of the fixing strap 21. Then, the bottom side of the fixing strap 21 is moved down from its original position, and then the fixing member 22 passes through the fixing strap 21 to limit the position, and at the same time, the adjusted position of the inner rod 113 is fixed.
