Description

Technical Field

[0001] The utility model relates to a novel seeder and belongs to the technical field of agricultural machinery and equipment. Background Art

[0002] In existing farming operations, most seed drills have relatively complex structures, resulting in a complex process for adjusting the sowing spacing. To solve the problem of low efficiency of traditional farming techniques, for example, a Chinese utility model patent with announcement number CN218868630U discloses "a composite rotary tillage, sowing and fertilization combined operation machine", which sows crop seeds through a seed tube installed on a double-disc furrowing, sowing and fertilization mechanism. This method of sowing through a seed tube has defects. The seed tube is usually suitable for seeds of a certain shape and size. For seeds of different shapes, sizes or weights, different seed tubes may need to be replaced. However, when the seed tube is sowing, the sowing spacing will not be fixed because the movement of the seeds in the tube is affected by multiple factors such as gravity and airflow. The structure of the seed tube is relatively complex, resulting in a complex spacing adjustment process. There is an urgent need for an agricultural machinery that is both simple in structure and can easily adjust the sowing spacing. Utility Model Content

[0003] In view of the above problems, the utility model provides a novel seeder, specifically, a novel seeder designed under a seeding box for increasing the number of sowing rows. Under the action of gravity, seeds enter a dividing plate slot provided on a replaceable dividing plate, and the replaceable dividing plate rotates to achieve seeding.

[0005] The replaceable indexing plate has 5 indexing plate slots and each indexing plate slot is 72° apart. There is a square hole in the center of the indexing plate to form a combination with the sleeve and fix it on the seeder shaft.

[0006] The replaceable indexing plate can be installed in a groove on one side of the seeder housing. After the seeder housing and the seeder baffle are fixed, a structural gap is formed between the replaceable indexing plate and the seeder housing and the seeder baffle in the radial direction and the axial direction.

[0007] The upper end of the seeder housing is provided with a feed inlet, the lower end is provided with a feed outlet, and one side is provided with an opening groove;

[0008] The indexing plate groove receives the crop seeds falling from the feed port, and after rotating a certain angle, the crop seeds fall into the discharge port to achieve seeding;

[0009] The sleeve is installed on the seeder shaft, and the center hole of the indexing plate and the sleeve cooperate with each other, thereby fixing the replaceable indexing plate on the seeder shaft;

[0010] The seeder partition and the seeder housing are connected by bolts to form a first fixation, and the number of bolts includes but is not limited to 4;

[0011] The seeding box is connected to the feed inlet at the upper end of the seeding device housing by bolts to form a second fixation, and the number of bolts includes but is not limited to 3;

[0012] The number of the seeders disposed on the seeder shaft includes but is not limited to 4;

[0013] The replaceable indexing plate is a cylindrical structure, and there is a square hole in the center of the replaceable indexing plate to be combined with the sleeve and fixed on the seeder shaft. The curved surface of the replaceable indexing plate is provided with indexing plate grooves, and the spacing between the indexing plate grooves is equal. The number of indexing plate grooves includes but is not limited to 5;

[0014] The replaceable indexing plate can be freely replaced according to the working conditions.

[0015] The benefits of the utility model are as follows: the utility model proposes a new type of seeder, which adopts a replaceable dividing plate to solve the problem of complicated sowing spacing adjustment process, adopts multiple coaxial seeders to solve the problems of low sowing efficiency and uneven crop spacing, overcomes the defects of low sowing efficiency and uneven seedling emergence in the rotary tillage sowing process in the prior art, makes it easier for farmers to adjust the sowing spacing and save labor energy.
