Description

Technical Field

[0001] This utility model relates to the field of corn planters, and in particular to a feed hopper for a corn planter. Background Technology

[0002] An existing patent (publication number: CN220292561U) discloses a feeding hopper for a corn planter, including a feeding mechanism. A docking frame is fixedly connected to the top of the feeding mechanism, and a feeding hopper is positioned above the docking frame. Through slots are formed on both inner walls of the docking frame, and locking blocks are fixedly connected to both outer walls of the feeding hopper. The locking blocks engage with the inner cavities of the corresponding through slots. Insertion holes are formed on both sides of one outer wall of the locking blocks. A shell is fixedly connected to both outer walls of the docking frame, and insertion rods are horizontally arranged on both sides of the inner cavity of the shell. One end of each insertion rod penetrates the adjacent side wall of the shell and engages with the corresponding insertion hole. However, this device, where "a feeding hopper is positioned above the docking frame," relies on the feeding hopper at the top of the feeding mechanism for feeding. Because the feeding hopper has a straight-through structure, the material inside will directly accumulate inside the feeding mechanism, potentially causing blockages and affecting the stability of the equipment. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a feeding hopper for a corn planter. The hopper is connected to the lower part of the protective frame and mounted on the feed inlet of the planter body. A rotating rotating cylinder shaft is driven by a rotating cylinder motor at the rear of the hopper, causing the rotating cylinder inside the rotating cylinder positioning groove to rotate. This rotation, guided by the frame, allows the rotating cylinder to deliver the temporarily stored material in the storage hopper to the feed inlet of the planter body in batches, preventing material accumulation and blockage at the feed inlet and thus increasing the stability of the equipment.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A feeding hopper for a corn planter includes an output hopper, a tilting cylinder, a threaded cylinder base, an internally threaded cylinder, a lead screw, a positioning shaft, and a protective frame. The lower parts of the output hopper and the protective frame are both fixedly connected to a connecting plate, which is bolted to the planter body. The output hopper has a tilting cylinder positioning groove inside, within which the tilting cylinder rotatably rotates. A tilting cylinder shaft groove is located at the rear of the tilting cylinder positioning groove, and a tilting cylinder shaft is located at the rear of the tilting cylinder. The tilting cylinder shaft groove is compatible with the tilting cylinder shaft, and the tilting cylinder shaft is connected to the tilting cylinder shaft. The tilting drum rotates inside the shaft groove. The rear of the output bucket is fixedly connected to the tilting drum motor. The output shaft of the tilting drum motor is fixedly connected to the tilting drum shaft. The front of the tilting drum has a turntable, which is fixedly connected to the guide rod. The tilting drum is adapted to the material limiting cylinder. The tilting drum is connected to the material limiting cylinder, and the material limiting cylinder slides inside the tilting drum. The lower part of the material limiting cylinder is fixedly connected to the guide seat. The guide rod is adapted to the guide seat, and the guide rod is connected to the guide seat, which slides inside the guide rod. The upper part of the material limiting cylinder is fixedly connected to the threaded cylinder base.

[0006] The threaded cylinder base is fixedly connected to the internal threaded cylinder, the front part of the guide seat is fixedly connected to the positioning plate, and the upper part of the turntable and the upper part of the positioning plate both have screw grooves. The screw grooves are adapted to the screw and are connected to the screw.

[0007] The lead screw rotates inside the lead screw groove, the internal threaded cylinder is threadedly connected inside the lead screw, the front part of the lead screw is fixedly connected to the hexagonal head, the front part of the positioning plate is fixedly connected to the positioning shaft, the side part of the output bucket is fixedly connected to the frame, and the front part of the frame has a positioning groove. Beneficial effects

[0008] 1. During the use of the feed hopper of this utility model seeder, after the connecting plate of the output hopper and the lower part of the protective frame is installed at the feed inlet of the seeder body, the flipping cylinder shaft is driven to rotate by the flipping cylinder motor at the rear of the output hopper. The flipping cylinder shaft drives the flipping cylinder inside the flipping cylinder positioning groove to rotate, and with the frame for guidance, the flipping cylinder delivers the material temporarily stored in the storage hopper to the feed inlet of the seeder body in batches, avoiding the accumulation of material at the feed inlet and causing blockage, thereby increasing the stability of the equipment.

[0009] 2. During the use of the feed hopper of this utility model seeder, the material is conveyed by the tipping cylinder inside the output hopper. If it is necessary to adjust the amount conveyed each time, the hexagonal head at the front of the positioning plate is rotated, which drives the lead screw to rotate and simultaneously drives the material limiting cylinder inside the tipping cylinder to adjust the width of the gap inside the tipping cylinder. This allows the equipment to adjust the amount conveyed each time according to the actual feeding needs of the seeder body, thereby increasing the adaptability of the equipment.

[0010] 3. During the use of the feed hopper of this utility model seeder, the material is stored in the storage hopper at the top of the output hopper, and the stirring motor at the rear of the storage hopper drives the stirring shaft to rotate, which in turn drives the stirring rod inside the storage hopper to rotate, thereby preventing the raw material inside the storage hopper from accumulating and arching, thus further increasing the stability of the equipment.
