[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0016] Embodiment:

[0017] A straw cleaning and anti-blocking device for a no-tillage seeder, as Figure 1 and 2 shown, includes a grass pressing gear 1 and a mounting connecting piece 2. The grass pressing gear 1 includes a gear body 11, as Figure 3 shown. On the outer circumferential surface of the gear body 11, grass scraping teeth 12 are radially arranged. And the grass pressing gear is made of 28MnB5 material. After heat treatment, the hardness can reach 38 - 43 HRC, having relatively high strength and toughness. The grass scraping teeth 12 are designed according to an anti-blocking curve, having good passability, reducing the accumulation of straw at the plow column, and improving the passability of the machine tool.

[0018] A connecting sleeve 13 is installed outside the central hole of the gear body. The connecting sleeve 13 is connected to the rotating part of the bearing 14, and the fixed part of the bearing is connected to the mounting connecting piece 2. When the grass scraping teeth rotate, they can lift the straw and send it to the rear of rotation. And the axis of the grass pressing gear is perpendicular to the setting direction of the mounting connecting piece.

[0019] The said mounting connecting piece 2 is used to support the grass pressing gear and install the grass pressing gear on one side of the main beam located at the furrow opener.

[0020] And the mounting connecting piece has an elastic deformation area, and the elastic deformation area provides a space for the grass pressing gear to move up and down. Because during use, due to the unevenness of the ground and the extrusion of the grass pressing gear after the straw converges, the grass pressing gear will move to a certain extent in the vertical direction;

[0021] In this embodiment, the adopted mounting connecting piece 2 includes an elastic connecting leg 21 and a mounting seat 22; the elastic connecting leg 21 is provided with a bending part 211, and the bending part 211 serves as the elastic deformation area. The elastic connecting leg is connected to the fixed part of the bearing, and the upper part of the elastic connecting leg is detachably connected to the mounting seat 22. The mounting seat is used to install the whole on the main beam and close to the furrow opener for installation. And the adjustable installation can adjust the vertical height of the elastic connecting leg, thereby realizing the adjustment of the height of the grass pressing gear.

[0022] Assemble the straw cleaning and anti-blocking device of the no-tillage seeder onto the seeder to provide a new type of no-tillage seeder, as Figure 1 and 2 shown. Install the mounting seat 22 on the main beam 3, and the furrow opener 4 is also assembled on the main beam 3. The grass pressing gear 1 faces the furrow opener 4 and is located on one side of the furrow opener together with the elastic connecting leg 21, and the bending direction of the bending part 211 is along the traveling direction of the furrow opener. There is a gap between the grass pressing gear 1 and the furrow opener 4. The working process of clearing straw is as follows:

[0023] When the seeder is moving forward, the plowshare of the furrow opener penetrates into the ground to a certain depth. However, the grass pressing gear may or may not contact the ground and may not rotate. Only when a certain amount of straw accumulates on the plow column of the furrow opener will the grass pressing gear come into play. The grass pressing gear contacts the ground. During the continuous forward movement, the grass pressing gear receives the pressure of the straw at the same time, and the frictional force of the ground causes it to rotate forward. During the rotation process, the butted straw is sent to the rear side of the rotation direction, that is, the rear side of the traveling direction, so that the straw is separated from the plow column, thereby reducing the straw on the plow leg of the machine tool and further reducing the congestion of the machine tool.

[0024] In the description of this specification, the description with reference to terms such as "one embodiment", "example", "specific example", etc. means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
