[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] A sludge scraping mechanism, such as Figures 3-5 As shown, the system includes a mounting base 1, a mounting beam 2, and a scraper assembly 3. The mounting beam 2 is mounted on the mounting base 1, and the scraper assembly 3 is mounted on the mounting beam 2. The mounting beam 2 is connected to the mounting base 1 and can rotate relative to the mounting base 1. The axis of rotation of the mounting beam 2 is its own length axis. The mounting beam 2 is equipped with a rotating operating handle 4. By rotating the operating handle 4, the mounting beam 2 can be rotated, thereby adjusting the position of the scraper assembly 3 around the circumference of the mounting beam 2. An elastic connecting member 5 is connected to the rotating operating handle 4. The elastic connecting member 5 is an elastic component such as a tension spring or spring. The elastic connecting member 5 is connected to the mounting base 1 by a connecting structure.

[0025] When the mud scraping mechanism is installed on the tillage tool, the installation base body 1 is connected with the tillage tool, the mud scraping assembly 3 is located on one side of the compacting roller 9 of the soil breaking mechanism, the elastic connecting piece 5 pulls the rotating handle 4 to enable the acting part of the mud scraping assembly 3 arranged on the installation beam 2 to be attached to the compacting roller 9, so that a good soil scraping effect is achieved. Due to the elasticity of the elastic connecting piece 5 itself, the installation beam 2 can be elastically swung in the circumferential direction, and the mud scraping assembly 3 can float according to the situation of the mud adhered on the compacting roller 9, so as to avoid hard contact between the soil scraping piece and the stubborn mud adhered on the compacting roller 9, thereby preventing the equipment from being damaged.

[0026] As an optional embodiment, a through hole is arranged on the installation base body 1, a rotating shaft is arranged in the through hole, and the rotating shaft is connected with the installation base body 1 through a bearing piece. The end of the installation beam 2 is connected with the rotating shaft, and the rotating handle 4 is arranged on the rotating shaft and connected with the rotating shaft. The rotating handle 4 is synchronously rotated with the installation beam 2.

[0027] As a preferred embodiment, the installation base body 1 is two, and the two installation base bodies 1 are respectively located at the two end positions of the installation beam 2. The two installation base bodies 1 are connected through a reinforcing beam, a reinforcing frame or the like. Each mud scraping assembly 3 is located between the two installation base bodies 1.

[0028] In some embodiments, the connecting structure includes a connecting plate 6 connected with the installation base body 1. The connecting plate 6 is provided with a connecting hole, and the elastic connecting piece 5 is connected with the connecting hole. The elastic connecting piece 5 can be detachably connected with the connecting hole through connecting hooks, connecting pins, bolts or the like. By disconnecting the elastic connecting piece 5 from the connecting plate 6, the installation beam 2 can be manually rotated, and the mud scraping assembly 3 can be adjusted, disassembled or replaced.

[0029] In another embodiment, as shown in Figures 3-5 the connecting structure includes a connecting plate 6 connected with the installation base body 1 and provided with a connecting slot. The connecting slot can be a straight slot, a curved slot or a U-shaped slot, and penetrates one end of the connecting plate 6. The elastic connecting piece 5 is provided with an operating handle 7, which cannot directly pass through the connecting slot. The elastic connecting piece 5 passes through the connecting slot, and the operating handle 7 is hung on the side of the connecting plate 6 away from the rotating handle 4. The operating handle 7 is connected with the connecting slot to realize the installation of the elastic connecting piece 5. The operating handle 7 can move along the connecting slot. When the operating handle 7 moves along the connecting slot and is separated from the connecting slot, the elastic connecting piece 5 is disconnected from the connecting plate 6. By connecting the operating handle 7 with the connecting slot on the connecting plate 6, the elastic connecting piece 5 can be quickly disassembled and assembled.

[0030] To prevent the operating handle 7 from being disconnected from the connecting slot during use of the mud scraping mechanism, the connecting plate 6 is obliquely arranged away from the mounting beam 2. The end of the connecting plate 6 communicating with the connecting slot is farther away from the mounting beam 2 than the opposite end. The connecting plate 6 is obliquely arranged in a hook shape as a whole, thereby effectively preventing the operating handle 7 from being disconnected. Further, the end of the connecting plate 6 communicating with the connecting slot is bent away from the mounting beam 2 and forms a bent anti-disconnection edge, thereby further preventing the operating handle 7 from being disconnected from the connecting plate 6.

[0031] Please refer to Figures 3-5 The mud scraping assembly 3 comprises a mounting plate 31 and mud scraping plates 32. The mounting plate 31 is detachably connected to the mounting beam 2 by bolts. The mounting plate 31 is provided with at least one mounting area arranged in a direction parallel to the mounting beam 2. The mounting area is used for mounting the mud scraping plates 32. The mounting area is provided with mounting holes. The mud scraping plates 32 are provided with waist holes. The mud scraping plates 32 are arranged behind the mounting area. The bolts pass through the waist holes and the mounting holes and fix the mud scraping plates 32. The mounting holes of the mounting area and the waist holes of the mud scraping plates 32 are both provided in multiple numbers, which facilitates stable mounting of the mud scraping plates 32. The length direction of the waist holes is perpendicular to the length direction of the mounting beam 2. The mounting positions of the mud scraping plates 32 can be manually adjusted, so that the mud scraping ends of the mud scraping plates 32 are flush. Moreover, the separate mounting of the mud scraping plates 32 facilitates replacement of a single mud scraping plate 32 that is severely worn.
