Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] In this article, when it is mentioned that the first component is located on the second component, this may mean that the first component may be directly formed on the second component, or the third component may be interposed between the first component and the second component. In addition, in the drawings, in order to effectively describe the technical content, the thickness of the components may be exaggerated or reduced.

[0053] Herein, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings.

For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0054] The terms used herein are only used to describe specific exemplary configurations and are not intended to be limited. As used herein, the singular articles "one", "an" and "the" may also be intended to include plural forms, unless it is clearly indicated above that this is not the case.

A return pipe 3, wherein the return pipe 3 is fixed inside the drive sleeve 1, and the inner end of the connecting mechanism 2 is suitable for abutting against the outer wall of the return pipe 3; wherein, after the connecting mechanism 2 is pushed inward to abut against the outer wall of the return pipe 3, the drive sleeve 1 rotates circumferentially, and the connecting mechanism 2 is suitable for scraping off impurities on the outer wall of the return pipe 3. Through the setting of the connecting mechanism 2, when the connecting mechanism 2 is pushed to move toward the return pipe 3, the cooling water in the driving sleeve 1 is suitable for flowing into the limiting sleeve 10 to cool the connecting mechanism 2 and the plow 5; and when the cleaning disk 24 abuts against the outer wall of the return pipe 3, the driving sleeve 1 drives the cleaning disk 24 to rotate synchronously, and the cleaning disk 24 can clean the impurities on the outer wall of the return pipe 3, thereby avoiding the temperature increase of the material or the plow 5 when the material is stirred.

The limiting sleeves 10 are arranged along the radial direction of the driving sleeve 1, the limiting sleeves 10 are hollow inside, and the inner diameter of the limiting sleeves 10 is greater than the outer diameter of the connecting rod 21. When the limiting sleeves 10 are in communication with the driving sleeve 1, the cooling water in the driving sleeve 1 is suitable for flowing into the cavity in the limiting sleeves 10, and the cooling water is suitable for cooling the connecting rod 21 to prevent the temperature of the connecting rod 21 and the coulter 5 from increasing due to friction during the mixing process.

[0063] Reference Figure 5The connection mechanism 2 comprises: a connecting rod 21, the inner end of which is slidably disposed in the limiting sleeve 10, and the connecting rod 21 and the limiting sleeve 10 are slidably sealed; that is, when the connecting rod 21 slides outward relative to the limiting sleeve 10, the cooling water in the limiting sleeve 10 will not leak outward from the gap between the connecting rod 21 and the limiting sleeve 10. A limiting plate 22, which is sleeved on the outer wall of the connecting rod 21, and the limiting plate 22 and the limiting sleeve 10 are slidably sealed; when the connecting rod 21 moves outward or inward relative to the limiting sleeve 10, it is suitable for driving the limiting plate 22 to slide outward or inward synchronously, and the limiting plate 22 is suitable for sealing the limiting sleeve 10 to prevent the cooling water in the limiting sleeve 10 from contacting the tension spring 23.
