Description

Technical Field

[0001] This utility model relates to the field of corn planting technology, and in particular to a corn planting and sowing device. Background Technology

[0002] In corn planting, the sowing depth directly affects corn growth and yield. Different soil conditions, climates and varieties require different sowing depths. For example, in fertile soil with good water retention, a sowing depth of 5-6 cm is conducive to corn rooting and nutrient absorption. Sandy soil has poor water retention, so the sowing depth needs to be increased to 6-8 cm. Different corn varieties have different seed sizes and soil-penetrating abilities. Early-maturing varieties have small seeds and weak soil-penetrating ability, so they are suitable for shallow sowing, while late-maturing varieties have large seeds and can be sown deeper.

[0003] However, the existing corn planting device with announcement number CN218218262U has a prominent problem in adjusting the pit depth. It relies on a fixed structure of digging and pulling blades to dig the pit, and cannot flexibly and accurately adjust the depth according to the actual needs such as soil texture and corn variety. It can only operate at a single depth, which may result in seeds being sown too deep, consuming too much energy and making it difficult for the seeds to emerge from the soil, thus reducing the germination rate; or being sown too shallow, making them susceptible to rain erosion, pecking by birds and animals, unstable rooting, and easy lodging later, which seriously affects the growth and yield of corn. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A corn planting and sowing device includes a frame, a sowing mechanism on one side of the top of the frame, and a soil leveling component and a soil breaking component on both sides below the frame, respectively.

[0007] The sowing mechanism includes a sowing hopper, which is positioned above the frame. Several feeding hoppers are connected to the bottom of the sowing hopper, and a guide tube is connected to the lower end of the feeding hopper at the bottom of the frame. A slotted column is connected to one end of the guide tube. A rotating shaft is rotatably installed inside the sowing hopper, and both ends of the rotating shaft pass through the sowing hopper. A dual-shaft motor is provided on one side of the sowing hopper at the top of the frame. One output end of the dual-shaft motor is connected to one end of the rotating shaft through a chain drive assembly. Several mounting slots are provided in the lower part of the sowing hopper, and the mounting slots are connected to the inner side of the feeding hopper and the sowing hopper.

[0008] As an improved technical solution, the sowing mechanism further includes a feeding disc, which is sleeved on the outside of the rotating shaft and located in the mounting groove. A material scooping groove is opened on one side wall of the feeding disc. Adjusting discs are symmetrically sleeved on the outer sides of the output ends of the dual-shaft motor. Protruding columns are installed at corresponding positions on the outer sides of the adjusting discs. The protruding columns are connected to the adjusting discs through adjusting components. A transmission frame is movably sleeved on the outer side of the protruding columns. A support rod is connected to the bottom of the transmission frame. A crossbar is connected to the lower ends of the two support rods below the frame. One end of the grooving column passes through the crossbar. A telescopic rod is fixedly installed inside the upper part of the grooving column. A sealing block is connected to the telescopic end of the telescopic rod. The sealing block is adapted to the grooving column. The lower end of the sealing block passes through the lower end of the grooving column.

[0009] As an improved technical solution, the adjustment assembly includes a screw, a groove is provided on one side of the adjustment disk, and the screw is rotatably installed in the groove. A threaded slider is sleeved on the outside of the screw, and one end of the slider is fixedly connected to a protrusion. One end of the screw extends to the outside of the adjustment disk and is connected to a handle.

[0010] As an improved technical solution, an adjusting plate is slidably installed in the material receiving trough, and an adjusting bolt is rotatably embedded in the top of the adjusting plate. The lower end of the adjusting bolt passes through the adjusting plate and is threadedly connected to the material feeding disc. A hexagonal groove is opened at the upper end of the adjusting bolt.

[0011] As an improved technical solution, the transmission frame and support rod combination structure is T-shaped, the discharge hopper is funnel-shaped, and the conduit is a flexible hose or telescopic tube.

[0012] As an improved technical solution, the soil breaking component includes a hydraulic cylinder, which is symmetrically arranged on one side of the top of the frame. The telescopic end of the hydraulic cylinder is connected to a mounting frame below the frame. A drive motor is fixedly installed at one end of the mounting frame, and several soil breaking blades are sleeved on the outer side of the output end of the drive motor and the inner side of the mounting frame.

[0013] As an improved technical solution, the leveling component includes a second hydraulic cylinder, which is symmetrically arranged on one side of the top of the frame, and the lower end of the second hydraulic cylinder is connected to a bulldozer component below the frame.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. This utility model can drive the grooving column to move up and down through a dual-shaft motor, thereby performing the grooving motion. At the same time, it can drive the rotating shaft to rotate the feeding disc, continuously picking up and conveying the material to the grooving column. After grooving, the sealing block is moved into the grooving column through the telescopic rod, allowing the seeds to fall into the grooves. This allows for automated grooving and seed placement of corn seeds, making operation simpler. At the same time, the grooving depth of the grooving column relative to the ground can be adjusted according to actual conditions to avoid sowing seeds too deep, which consumes a lot of energy and makes it difficult for the seeds to emerge, resulting in a lower germination rate, or sowing seeds too shallow, which makes them susceptible to rain erosion, pecking by birds and animals, and unstable rooting, making them prone to lodging later, seriously affecting the growth and yield of corn.

[0016] 2. The height of the adjusting plate can be adjusted as needed to adjust the number of seeds taken by the feeding tray.

[0017] 3. This utility model can break up the soil to loosen it, and after the seeds are filled into the trench, the soil can be pushed to fill the trench, thereby covering the seeds with soil, making it more versatile and convenient to use. Attached Figure Description

[0030] like Figure 1 - Figure 5As shown in the figure, this embodiment provides a corn planting and sowing device, including a frame 1. A sowing mechanism is provided on one side of the top of the frame 1, and a soil leveling component and a soil breaking component are provided on both sides below the frame 1, respectively. The sowing mechanism includes a sowing hopper 2, which is located above the frame 1. Several feeding hoppers 3 are connected to the bottom of the sowing hopper 2, and a guide tube 4 is connected to the bottom of the frame 1 at the lower end of the feeding hopper 3. A slotted column 5 is connected to one end of the guide tube 4. A rotating shaft 17 is rotatably installed inside the sowing hopper 2, and both ends of the rotating shaft 17 pass through the sowing hopper 2. A dual-shaft motor 6 is provided on one side of the sowing hopper 2 at the top of the frame 1. One output end of the dual-shaft motor 6 is connected to one end of the rotating shaft 17 through a chain transmission component 18. Several mounting slots 22 are opened in the lower part of the sowing hopper 2, and the mounting slots 22 are connected to the feeding hopper 3 and the inner side of the sowing hopper 2.

[0031] In this example, the seeding mechanism also includes a feeding disc 19, which is sleeved on the outside of the rotating shaft 17 and located in the mounting groove 22. A material-collecting groove is provided on one side wall of the feeding disc 19. Adjusting discs 7 are symmetrically sleeved on the outer sides of the output ends of the dual-shaft motor 6. Corresponding protrusions 8 are installed on the outer sides of the adjusting discs 7. The protrusions 8 are connected to the adjusting discs 7 via adjusting components. A transmission frame 9 is movably sleeved on the outer side of the protrusions 8. Support rods 10 are connected to the bottom of the transmission frame 9. Two support rods... A crossbar 11 is connected to the lower end of the frame 1. One end of the grooving column 5 passes through the crossbar 11. A telescopic rod 12 is fixedly installed inside the upper part of the grooving column 5. The telescopic end of the telescopic rod 12 is connected to a sealing block 13. The sealing block 13 is adapted to the grooving column 5. The lower end of the sealing block 13 passes through the lower end of the grooving column 5 so that sowing and grooving share the same power source. This allows seeds to be placed immediately after grooving, making it convenient to use. The depth of the grooving column 5 on the ground can be adjusted according to the actual planting needs.

[0032] In this example, the adjustment assembly includes a screw 14, a groove 16 is provided on one side of the adjustment disk 7, and the screw 14 is rotatably installed in the groove 16. A threaded slider 15 is sleeved on the outside of the screw 14, and one end of the slider 15 is fixedly connected to the protrusion 8. One end of the screw 14 extends to the outside of the adjustment disk 7 and is connected to a handle. In this example, when the protrusion 8 is located closest to the center of the adjustment disk 7 and at its highest point, the distance between the crossbar 11 and the bottom surface of the frame 1 is greater than the radius of the adjustment disk 7; so as to adjust the distance between the protrusion 8 and the center of the adjustment disk 7, thereby changing the depth of the groove of the slotted column 5.

[0033] In this example, an adjusting plate 20 is slidably installed in the material receiving trough. An adjusting bolt 21 is rotatably embedded in the top of the adjusting plate 20, and the lower end of the adjusting bolt 21 passes through the adjusting plate 20 and is threadedly connected to the material feeding plate 19. The upper end of the adjusting bolt 21 has a hexagonal groove so as to adjust the height position of the adjusting plate 20 in the material receiving trough as needed, thereby adjusting the amount of material taken out by the material receiving trough.

[0034] In this example, the combined structure of the transmission frame 9 and the support rod 10 is T-shaped, the hopper 3 is funnel-shaped, and the conduit 4 is a flexible hose or telescopic tube so that it can cooperate with the movement of the slotted column 5 and avoid affecting its movement.

[0035] like Figure 1 As shown, in this example, the soil breaking component includes a hydraulic cylinder 23, which is symmetrically arranged on one side of the top of the frame 1. The telescopic end of the hydraulic cylinder 23 is connected to a mounting frame 24 below the frame 1. A drive motor 25 is fixedly installed at one end of the mounting frame 24. Several soil breaking blades 26 are sleeved on the outer side of the output end of the drive motor 25 and the inner side of the mounting frame 24 to break up the ground, realize the function of turning over and loosening the soil, and facilitate the trenching column 5 to trench.

[0036] In this example, the soil leveling component includes a second hydraulic cylinder 27, which is symmetrically arranged on one side of the top of the frame 1. The lower end of the second hydraulic cylinder 27 is connected to a bulldozer 28 below the frame 1 to level the soil and fill the trench, thereby covering the seeds with soil.

[0037] In use, the dual-axis motor 6 and drive motor 25 are started, causing drive motor 25 to drive the soil-breaking blade 26 to rotate. The height of the blade is adjusted using hydraulic cylinder 23, thus breaking and loosening the soil. The operation of the dual-axis motor 6 then drives the adjusting disc 7 to rotate. The adjusting disc 7, through the convex column 8, drives the transmission frame 9, causing the support rod 10 to move up and down. The support rod 10 then drives the crossbar 11 and several slotting columns 5 to move up and down, causing the slotting columns 5 and the sealing block 13 to impact the top surface and create a slot. Simultaneously, the operation of the dual-axis motor 6 drives the rotating shaft 17 through the chain transmission assembly 18. As the rotating shaft 17 rotates, it drives the feeding plate 19 to rotate, causing the grooving column 5 to move downwards to create grooves. Simultaneously, the feeding port of the feeding plate 19 rotates downwards. When grooving is complete, the feeding port moves from the top to the bottom, allowing the seeds to fall into the feeding hopper 3 and be transported into the grooving column 5. At the same time, the telescopic rod 12 moves the sealing block 13 into the grooving column 5, allowing the corn seeds inside the grooving column 5 to be placed into the grooves. Then, as the grooving column 5 moves upwards to its original position, the feeding slot on the feeding plate 19 also moves upwards. When the grooving column 5 reaches its top position, the feeding port moves downwards. At the highest point, this process can be repeated continuously to open trenches and place seeds. After seeding, the frame 1 moves forward, simultaneously moving the bulldozer 28. The hydraulic cylinder 27 adjusts the height of the bulldozer 28, causing it to push soil to fill the trenches. This allows for automatic trenching, seed placement, and soil covering, making it more convenient to use. Furthermore, if the trenching depth needs adjustment, before using the equipment, the screw 14 is rotated by turning the handle, causing the slider 15 to move away from the center of the adjusting plate 7. This, in turn, moves the convex column 8 synchronously, thereby adjusting the trenching depth. The depth of the grooved column 5 can be adjusted according to the actual situation to avoid the situation where the seeds are sown too deep, which consumes a lot of energy and makes it difficult to emerge from the soil, resulting in a lower germination rate, or sown too shallow, which makes them susceptible to rain erosion, pecking by birds and animals, and unstable rooting, making them prone to lodging later, which seriously affects the growth and yield of corn. By turning the adjusting bolt 21 with a hexagonal wrench, the adjusting plate 20 can be moved up and down in the feeding trough, thereby changing the depth of the feeding trough and adjusting the amount of material fed in the feeding trough. This avoids putting too many corn seeds in one pit, making it convenient to use and more practical.

[0038] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
