Description

Technical Field

[0001] The utility model relates to the technical field of furrowing mechanisms, in particular to a furrowing mechanism for corn sowing and fertilization. Background Art

[0002] There are two furrowing methods for seed drills currently in use. One is the pulling furrow method, in which seeds fall from the inner hole of a steel pipe into the furrow formed by the steel pipe. The seeds contact the soil, resulting in a high germination rate, but are easily caught on straw, and normal seeding cannot be performed on plots where straw is returned to the field. The other is the rolling furrow method, also known as a disc rolling furrow seeder, in which two disc shafts are fixed on a bracket, each with an identical disc installed. The front edge is tightly closed and the rear edge is 5 to 6 cm away, and a furrow is formed when rolling forward.

[0003] For example, a Chinese patent with publication (announcement) number CN104067731A discloses a furrowing mechanism for a seeder, in which two furrowing discs are mounted on disc shafts on both sides of a bracket, and ground pressing rollers, gears, a driving sprocket, a chain, a seed guide tube, a seed remover, and a seed box are mounted on a frame. A furrowing disc is provided with weeding teeth on its edge, which is driven to rotate by a driven sprocket to remove straw at the bottom of the furrow to the ground, so that the seeds fall into the soil.

[0004] Although the above technical solution solves the corresponding technical problem, the above technical solution still has the following defects:

[0005] The above technical solution is not convenient for adjusting the depth of the pressure groove, and therefore is difficult to be applied to the planting of different varieties of corn. Utility Model Content

[0006] The purpose of the utility model is to provide a corn sowing and fertilizing furrowing mechanism. First, the side of the driving mounting frame is installed on the seeder, and then the seeder drives the driving mounting frame to move on the land. While the driving mounting frame is moving, the loosening motor first drives the loosening roller to turn the soil, and then the soil is furrowed by the furrowing wheel. Moreover, the adjusting bolt is rotated by rotating the hand wheel, and the height of the furrowing wheel is adjusted under the meshing action of the teeth of the internal thread, so that furrows of different depths can be rolled, thereby improving the applicability of the utility model.

[0007] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include:

[0008] A corn sowing, fertilizing and furrowing mechanism, comprising:

[0009] Drive mounting frame;

[0010] A loosening structure for loosening soil, the loosening structure comprising a loosening frame fixedly connected to the bottom of the drive mounting frame, and a loosening assembly is installed on the loosening frame;

[0011] A trenching structure for trenching, the trenching structure comprises a mounting seat fixedly connected to the side of the driving mounting frame, an adjusting component is installed on the mounting seat, and a trenching component is installed at the bottom of the adjusting component.

[0012] In the above-mentioned corn sowing, fertilizing and furrowing mechanism, the loosening assembly includes a loosening motor fixedly connected to the side of the loosening frame, and a loosening roller is fixedly connected to the output shaft of the loosening motor.

[0013] In the above-mentioned corn sowing, fertilizing and furrowing mechanism, the adjusting component includes an adjusting bolt threadedly connected to the mounting seat, and an internal thread meshing with the adjusting bolt is provided on the mounting seat at a position corresponding to the adjusting bolt.

[0014] The above-mentioned furrowing mechanism for corn sowing and fertilization, wherein the furrowing assembly includes an adjusting seat, the center of the top of the adjusting seat is rotatably connected to the bottom of the adjusting bolt through a connecting bearing, the bottom of the adjusting seat is fixedly connected to a furrowing frame, and a furrowing wheel is rotatably installed on the furrowing frame through a connecting shaft.

[0015] In the above-mentioned corn sowing, fertilizing and furrowing mechanism, one end of the loosening roller away from the loosening motor is rotatably connected to the side surface of the loosening frame through a limit bearing.

[0016] In the above-mentioned corn sowing, fertilizing and furrowing mechanism, both sides of the bottom of the mounting seat are fixedly connected with limiting telescopic rods, and the bottom of the limiting telescopic rod is fixedly connected to the top of the adjusting seat.

[0017] In the above-mentioned corn sowing, fertilizing and furrowing mechanism, a rotating hand wheel for rotating the adjusting bolt is fixedly connected to the top of the adjusting bolt.

[0018] The utility model has at least the following beneficial effects:

[0019] In the utility model, a corn sowing and fertilizing furrowing mechanism is realized. First, the side of the driving mounting frame is installed on the seeder, and then the seeder drives the driving mounting frame to move on the land. While the driving mounting frame moves, the loosening motor drives the loosening roller to turn the soil, and then the soil is furrowed by the furrowing wheel. Moreover, the adjusting bolt is rotated by rotating the hand wheel, and the height of the furrowing wheel is adjusted under the meshing action of the teeth of the internal thread, so that furrows of different depths can be rolled, thereby improving the applicability of the utility model.
