Description

Technical Field

[0001] This utility model relates to the field of agricultural sowing equipment technology, and in particular to a soil covering device for a corn fertilizer planter. Background Technology

[0002] Corn planting involves using a corn planter to sow seeds onto a suitable soil layer. During planting, it's crucial to ensure that the seeds are spaced evenly, at a consistent depth, and within the same row. Before planting, a furrow opener is used to create planting furrows. Then, a seed metering tube dispenses the seeds into the furrows. Finally, a soil covering tray is used to cover the seeds, pressing the soil from both sides of the furrow towards the center.

[0003] When using the existing corn planting and covering device, the position of the furrow opener and the covering plate needs to be adjusted one by one when adjusting the spacing of corn planting. It is difficult to adjust the position of the furrow opener and the covering plate synchronously according to the actual situation to ensure that the covering plate is always located on both sides of the planting furrow, which can easily cause deviation during covering.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a soil covering device for a corn fertilizer planter. By setting an adjustment mechanism, the positions of the plow blade and the two feeding discs are adjusted synchronously to ensure that the furrows opened by the plow blade are always located between the two feeding discs, thus ensuring that the soil is evenly covered on the seeds or fertilizer, thereby solving the problems mentioned in the background art.

[0006] The purpose of this utility model can be achieved through the following technical solution: a soil covering device for a corn fertilizer planter, including a connecting frame, a storage box fixedly installed on the top of the connecting frame, an installation frame provided at one end of the connecting frame, a pressure roller movably connected vertically on the installation frame, a traction frame provided at the end of the connecting frame away from the pressure roller, and an adjustment mechanism provided on the connecting frame.

[0007] The adjustment mechanism includes a sliding rod 1 fixedly connected to the inner wall of the connecting frame. The sliding rod 1 passes through and is slidably connected to a sliding seat.

Connecting frames extending towards the movable frame 1 and fixedly connected to both sides of the movable frame 1 are fixedly connected to both sides of the sliding seat.

[0008] Preferably, a seeding box is fixedly installed at the bottom of the storage box and is connected to the storage box. A flexible hose is connected to the outlet of the seeding box, and a sleeve for inserting the flexible hose is fixedly installed on the outer wall of the plow blade.

[0009] Preferably, multiple sliding seats and movable frames are provided and spaced apart on sliding rod 1 and sliding rod 2. A fixing knob 1 is screwed onto the upper surface of the movable frame 1, and the fixing knob 1 passes through the movable frame 1 and abuts against the sliding rod 2.

[0010] Preferably, the connecting arm passes through the second movable frame and is slidably connected to the second movable frame in the horizontal direction. A second fixing knob is screwed onto the surface of the second movable frame, and the second fixing knob passes through the second movable frame and abuts against the surface of the connecting arm.

[0023] 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.

[0024] Example 1:

[0025] This embodiment addresses the problem of difficulty in synchronously adjusting the positions of the furrow opener and the covering plate in corn planting and covering devices, ensuring that the covering plate is always located on both sides of the planting furrow and preventing deviation caused by soil covering.

[0026] Please see Figure 1 - Figure 5 As shown, this embodiment is a soil covering device for a corn fertilizer planter, including a connecting frame 1. A storage box 2 is fixedly installed on the top of the connecting frame 1. The storage box 2 can be provided with mounting cavities for placing seeds and waste materials respectively. A mounting frame 7 is provided at one end of the connecting frame 1. A pressure roller 19 is vertically movably connected to the mounting frame 7. A traction frame 9 is provided at the end of the connecting frame 1 away from the pressure roller 19. An adjustment mechanism is provided on the connecting frame 1.

[0027] The adjustment mechanism includes a sliding rod 4 fixedly connected to the inner wall of the connecting frame 1. The sliding rod 4 passes through and is slidably connected to a sliding seat 5. A plow blade 6 is fixedly connected to the lower surface of the sliding seat 5. A sliding rod 8 is fixedly connected to the inner wall of the connecting frame 1 on the side near the sliding seat 5. The sliding rod 8 passes through and is slidably connected to a movable frame 11. Connecting arms 12 are fixedly connected to both sides of the movable frame 11. The connecting arms 12 are square tubes, and the surface of the connecting arms 12 has an opening groove for bolts to pass through and slide.

[0028] Loosening the nut facilitates the sliding seat 5 to slide on the sliding rod 4. A movable frame 13 is horizontally slidably connected to the connecting arm 12. Material feeding discs 15 are installed on both sides of the bottom of the movable frame 13. Connecting frames 10, which extend to the movable frame 11 and are fixedly connected to both sides of the movable frame 11, are fixedly connected to both sides of the sliding seat 5. When the sliding seat 5 moves on the sliding rod 4, the movable frame 11 is pulled by the connecting frame 10 to slide on the sliding rod 8, thereby synchronously adjusting the position of the plow blade 6 on the sliding seat 5 and the position of the two material feeding discs 15. This ensures that the groove opened by the plow blade 6 is always located between the two material feeding discs 15. The two inclined material feeding discs 15 move on both sides of the groove opened by the plow blade 6 and cover the soil on both sides of the groove with soil after material feeding, thus completing the soil covering treatment after material feeding.

[0029] A seeding box 3 is fixedly installed at the bottom of the storage box 2 and is connected to the storage box 2. The seeding box 3 is a cylindrical shaft and has two sets corresponding to fertilizer and seeds respectively. A rotating shaft is inserted through the seeding box 3. The rotating shaft is connected to the roller on the connecting frame 1 through a belt or chain. The rotation of the rotating shaft realizes automatic feeding of corn seeds and fertilizer. A flexible hose is connected to the discharge port of the seeding box 3. A sleeve for the flexible hose is fixedly installed on the outer wall of the plow blade 6. The corn seeds in the storage box 2 fall into the seeding box 3 and are guided by the flexible hose to the sleeve on the plow blade 6 for feeding. The sleeve can be symmetrically set on the front and rear sides of the plow blade 6 for feeding corn seeds and fertilizer respectively.

[0030] Multiple sliding seats 5 and movable frames 11 are provided and spaced apart on sliding rods 4 and 8, which can realize multi-row feeding at the same time and improve the feeding speed of corn planting. A fixing knob 16 is screwed onto the upper surface of the movable frame 11. The fixing knob 16 passes through the movable frame 11 and abuts against the sliding rod 8. Rotating the fixing knob 16 on the movable frame 11 can further lock the position of the movable frame 11 and prevent the movable frame 11 from being subjected to excessive force and causing the connecting frame 10 to deform.

[0031] The connecting arm 12 passes through the movable frame 13 and slides horizontally connected to the movable frame 13. A fixed knob 17 is screwed onto the surface of the movable frame 13. The fixed knob 17 passes through the movable frame 13 and abuts against the surface of the connecting arm 12. Rotating the fixed knob 17 on the movable frame 13 releases the lock on the position of the fixed knob 17, thereby allowing the distance between the two movable frames 13 to be adjusted up and down, thereby adjusting the distance between the two feeding discs 15.

[0032] The bottom of the second mobile frame 13 is detachably connected to a connecting strip 14. The end of the connecting strip 14 is fixedly connected to the material feeding disc 15. Two adjacent material feeding discs 15 are symmetrically arranged. The connecting strip 14 is detachably connected to the second mobile frame 13. By rotating the connecting strip 14, the angle of the material feeding disc 15 on the connecting strip 14 can be adjusted, thereby ensuring that the material feeding disc 15 can achieve sufficient soil covering.

[0033] Example 2:

[0034] This embodiment is used to solve the problem that existing devices cannot guarantee the soil thickness after covering.

[0035] Please see Figure 1 - Figure 5 As shown in this embodiment, a soil covering device for a corn fertilizer planter has two symmetrically arranged movable rods 21 on both sides of the inner wall of the mounting frame 7 via pins. A pressure roller 19 is located between the two movable rods 21 and is rotatably connected to the movable rods 21. A connecting rod 20 is fixedly connected between the two movable rods 21. A hydraulic rod 18 is movably connected to the side of the mounting frame 7 away from the connecting frame 1. The telescopic end of the hydraulic rod 18 passes through the connected rod 20 and is movably connected to the connecting rod 20. When the hydraulic rod 18 is activated, the telescopic end of the hydraulic rod 18 pushes or pulls the connecting rod 20, which can adjust the position of the pressure roller 19 in the vertical direction, thereby further adjusting the thickness of the soil covering.

[0036] Combining Example 1 and Example 2

[0037] By setting an adjustment mechanism, the positions of the plow blade 6 and the material-distributing disc 15 can be adjusted as needed. The sliding seat 5 slides on the sliding rod 4, and the connecting frame 10 pulls the moving frame 11 on the sliding rod 8, simultaneously adjusting the positions of the plow blade 6 and the two material-distributing discs 15. This ensures that the furrows opened by the plow blade 6 are always located between the two material-distributing discs 15. The material-distributing discs 15 move on both sides of the furrows opened by the plow blade 6, covering the soil on both sides of the furrows after the material is distributed, thus completing the soil covering treatment after the material is distributed. This ensures that the soil is evenly covered on the seeds or fertilizer. By extending and retracting the hydraulic rod 18, the position of the pressure roller 19 in the vertical direction can be adjusted, allowing the soil thickness after covering to be adjusted according to actual needs. This ensures that the soil achieves ideal compaction and covering effect under the action of the pressure roller 19, thereby meeting the soil thickness requirements of different crops.

[0038] like Figure 1 - Figure 5 As shown, the working process and principle of this utility model are as follows:

[0039] Step 1: Loosen the nut on the feeding disc 15 and push the sliding seat 5 to slide on the sliding rod 4. The moving frame 11 and the sliding seat 5 are fixedly connected by the connecting frame 10. Simultaneously adjust the position of the plow blade 6 on the sliding seat 5 and the position of the two feeding discs 15. The groove opened by the plow blade 6 is always located between the two feeding discs 15. The two inclined feeding discs 15 move on both sides of the groove opened by the plow blade 6 and cover the soil on both sides of the groove into the groove after feeding, completing the soil covering treatment after feeding. Adjusting the distance between adjacent sliding seats 5 can adjust the spacing of corn planting, thereby achieving flexible planting.

[0040] Step 2: Start the hydraulic rod 18. The telescopic end of the hydraulic rod 18 pushes the connecting rod 20. The pressure roller 19 rotates with the fixed knob 17 and the movable connection of the mounting frame 7 as the fulcrum, thereby adjusting the position of the pressure roller 19 in the vertical direction and further adjusting the thickness of the soil cover.
