[0001] This utility model relates to the field of agricultural seeding machine technology, and in particular to a new type of multifunctional mechanical seeding machine. Background Technology

[0002] A new type of multifunctional mechanical seeder is an advanced piece of equipment used for agricultural sowing operations. It has multiple functions and features, aiming to improve sowing efficiency, reduce labor costs, and improve the production efficiency and quality of crop planting. Sowing is one of the important links in agricultural production, which directly affects the yield and quality of crops.

[0003] A search revealed that Chinese patent document CN216601055U discloses a novel multifunctional agricultural seeder, comprising a base plate, a mounting frame fixedly connected to the surface of the base plate, a material box fixedly mounted on one end of the mounting frame, a pump body fixedly mounted on one side of the material box, a fixed pipe fixedly connected to the outlet of the pump body, a sliding tube slidably mounted on one end of the fixed pipe, a horizontal tube fixedly connected to one end of the sliding tube, needle tubes evenly mounted on one side of the horizontal tube, and return springs fixedly connected to both ends of the other side of the horizontal tube. One end of each return spring is fixedly connected to both sides of the mounting frame, and a long groove is provided on one side of the mounting frame. A pressure rod is slidably connected to the side of the long groove, and one end of the pressure rod is fixedly connected to one end of the horizontal tube. This design greatly improves the convenience and stability of use, ensuring uniform and efficient sowing.

[0004] The aforementioned patent specification mentions that "the material box and pump body are connected by a mounting bracket on the base plate, which can continuously deliver the inoculum liquid, which is convenient and efficient. The horizontal tube and needle tube are installed by connecting the sliding tube with the fixed tube, which can be pushed down and inserted into the inoculum bag for synchronous sowing, ensuring uniformity. At the same time, by installing support rollers and belts, combined with the side clamps, the inoculum bag can be transported and rotated for adjustment, which is stable and efficient." Although the aforementioned patent can continuously deliver the inoculum liquid and sow synchronously, the seeds may become clogged when entering the material box, resulting in seed shortages during sowing. Therefore, a new type of multi-functional mechanical seeder is proposed to solve the above problems. Utility Model Content

[0005] Based on the problems existing in the above-mentioned background technology, this utility model proposes a new type of multi-functional mechanical seeder, which solves the problem that existing agricultural seeders may experience blockage when seeds enter the feed hopper, resulting in seed shortages during sowing.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows: This utility model provides a novel multifunctional mechanical seeder, including a fixed frame for fixed connection with a vehicle frame. A feeding box is provided on the top of the fixed frame, and a box cover is provided on the top of the feeding box. A connecting compartment is provided inside the feeding box. The top and bottom of the connecting compartment are respectively provided with a feeding port and a discharging port. A motor is provided on one side of the feeding box. A fixed column is provided at the output end of the motor. One end of the fixed column passes through the feeding box and the connecting compartment and is located inside the connecting compartment. A plurality of first gears are evenly spaced along the axial direction of the fixed column. An adjusting ring is fixedly connected to the outer circumference of each first gear. The adjusting ring is fixedly connected to the inner wall of the connecting compartment. An adjusting port is provided through the top and bottom of the adjusting ring. The adjusting ports at the top and bottom of the adjusting ring are aligned with the feeding port and the discharging port, respectively. At least one feeding pipe is provided at the bottom of the feeding box. The top end of the feeding pipe is fixedly connected to the feeding box and located below the feeding port, while the bottom end of the feeding pipe faces the sowing ground.

[0007] Furthermore, the fixing frame has a rectangular frame structure, the feeding box has a long box-shaped structure, the axis of the fixing column coincides with the length direction of the feeding box, and the feeding port and the feeding port are both set along the length direction of the feeding box.

[0008] Furthermore, a protective box is fitted around the motor, and the protective box is fixedly connected to one side wall of the feeding box.

[0009] Furthermore, multiple trenchers are provided in front of the fixing frame; the number of feeding pipes is the same as the number of trenchers, each trencher is matched with one feeding pipe, and the bottom end of each feeding pipe is located on the rear side of the trencher.

[0010] Furthermore, each of the trenchers is connected to the fixed frame via an adjustment assembly. The adjustment assembly includes an adjustment column, a fixed plate slidably connected to the middle of the adjustment column, one side of the fixed plate being connected to the fixed frame, a limit plate being provided at the top of the adjustment column, a spring being provided between the limit plate and the fixed plate, the spring being sleeved on the outer circumference of the adjustment column, and the two ends of the spring being fixedly connected to the lower end face of the limit plate and the upper end face of the fixed plate, respectively. A trencher is provided at the bottom of the adjustment column.

[0011] Furthermore, a plurality of teeth are vertically spaced on one side of the adjusting column, a second gear is provided inside the fixing plate to mesh with the plurality of teeth, and a handle for driving the second gear to rotate is provided outside the fixing plate.

[0012] Furthermore, a positioning post is provided with a downward protrusion on the lower end of the limiting plate.

[0013] Compared with existing agricultural seeders, the beneficial effects of this utility model are: 1. This utility model provides a novel multi-functional mechanical seeder. When sowing, the cover is opened and seeds are placed inside the feeding box. At this time, the motor is started, and the fixed column rotates under the drive of the motor. The rotation of the fixed column will drive the first gear to rotate. The seeds enter the connecting chamber through the feeding port. Some seeds enter the adjusting ring. The seeds will enter the tooth gap between the adjusting ring and the first gear. After the rotation of the first gear, the seeds will be weighed and then fall into the connecting chamber through the adjusting port. Then, they will enter the feeding pipe through the feeding port. The other part will directly enter the feeding pipe through the feeding port. This can prevent seed blockage during feeding and avoid seed shortage.

[0014] 2. This utility model provides a novel multi-functional mechanical seeder. The furrow opener is connected to the fixed frame via an adjusting assembly. When the furrow depth needs adjustment, turning the handle drives the second gear to rotate. The rotation of the second gear moves the adjusting column, thereby adjusting the position of the furrow opener. As the adjusting column moves, it compresses a spring. The spring, while compressed, absorbs external pressure and simultaneously generates a reaction force on the fixed plate and the limiting plate. The limiting plate limits the spring, preventing it from deforming violently and falling off. This allows for adjustment of the adjusting column's height. When the adjusting column contacts the fixed plate, it stops descending, preventing the furrow from becoming too deep and affecting the germination rate. Attached Figure Description

One end of the fixed column 5 passes through the feeding box 2 and the connecting chamber 6 and is located inside the connecting chamber 6. A plurality of first gears 12 are evenly spaced along the axial direction of the fixed column 5. An adjusting ring 7 is fixedly connected to the outer circumference of each first gear 12. The adjusting ring 7 is fixedly connected to the inner wall of the connecting chamber 6. An adjusting port 10 is provided through the top and bottom of the adjusting ring 7. The adjusting ports 10 at the top and bottom of the adjusting ring 7 are aligned with the feeding port 8 and the discharging port 9, respectively.

[0025] At least one feeding pipe 21 is provided at the bottom of the feeding box 2. The top end of the feeding pipe 21 is fixedly connected to the feeding box 2 and located below the feeding port 9. The bottom end of the feeding pipe 21 is set towards the sowing ground.

[0026] When sowing, open the box cover 11 and put the seeds into the feeding box 2. At this time, start the motor 4. Driven by the motor 4, the fixed column 5 rotates. While the fixed column 5 rotates, it will drive the first gear 12 to rotate. The seeds enter the connecting chamber 6 through the feed port 8. Some seeds enter the adjusting ring 7. The seeds will enter the tooth gap between the adjusting ring 7 and the first gear 12. After the rotation of the first gear 12, the seeds will be distributed. Then, they will fall into the connecting chamber 6 through the adjusting port 10 and then enter the feeding pipe 21 through the feeding port 9. The other part will directly enter the feeding pipe 21 through the feeding port 9. This can prevent seed blockage during feeding and avoid seed shortage.

[0027] Furthermore, the fixing frame 1 has a rectangular frame structure, the feeding box 2 has a long box-shaped structure, the axis of the fixing column 5 coincides with the length direction of the feeding box 2, and the feeding port 8 and the feeding port 9 are both arranged along the length direction of the feeding box 2.

[0028] Furthermore, a protective housing 3 is fitted around the motor 4, and the protective housing 3 is fixedly connected to one side wall of the feeding box 2. The protective housing 3 can protect the motor 4 and prevent accidental activation.

[0029] Furthermore, a plurality of furrow openers 20 are provided in front of the fixing frame 1; the number of feeding pipes 21 is the same as the number of furrow openers 20, and each furrow opener 20 is matched with one feeding pipe 21, with the bottom end of each feeding pipe 21 located at the rear of the furrow opener 20. As the vehicle frame drives, the furrow openers 20 open furrows in the soil, facilitating the direct placement of seeds from the feeding pipes 21 into the opened furrows, thereby improving sowing efficiency.

[0030] like Figure 1 and Figure 4 As shown, each of the trenchers 20 is connected to the fixed frame 1 via an adjustment assembly. The adjustment assembly includes an adjustment column 14, a fixed plate 13 is slidably connected to the middle of the adjustment column 14, one side of the fixed plate 13 is connected to the fixed frame 1, a limit plate 15 is provided at the top of the adjustment column 14, a spring 16 is provided between the limit plate 15 and the fixed plate 13, the spring 16 is sleeved on the outer circumference of the adjustment column 14, and the two ends of the spring 16 are fixedly connected to the lower end face of the limit plate 15 and the upper end face of the fixed plate 13, respectively.

[0031] The adjusting column 14 has multiple teeth vertically spaced on one side. The fixing plate 13 has a second gear 18 inside that meshes with the teeth. The fixing plate 13 has a handle 19 outside that drives the second gear 18 to rotate. The lower end of the limiting plate 15 has a positioning column 17 protruding downwards.

[0032] The furrow opener 20 is connected to the fixed frame 1 via an adjustment assembly. When the furrowing depth of the furrow opener 20 needs to be adjusted, turning the handle 19 will drive the second gear 18 to rotate. When the second gear 18 rotates, it will drive the adjusting column 14 to move, thereby adjusting the position of the furrow opener 20 and adjusting the sowing depth to flexibly adapt to different sowing needs. While moving, the adjusting column 14 will compress the spring 16. The spring 16 absorbs external pressure while being compressed, and at the same time, it generates a reaction force on the fixed plate 13 and the limiting plate 15. The limiting plate 15 can limit the spring 16 to prevent it from deforming violently and falling off. At this time, the height of the adjusting column 14 can be adjusted. When the positioning column 17 contacts the fixed plate 13, it will stop moving downward to avoid the furrow being too deep and affecting the germination rate.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
