For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. Example

[0031] like Figure 1-4 As shown, the present application proposes a mud scraping structure for a double-axis rotary tillage fertilization seeder, comprising a seeder body 1 and a pressing roller 2 arranged at the bottom thereof, and also comprising:

[0032] A scraper 4 is connected to the bottom end of the seeder body 1 and is located on one side of the pressing roller 2. The scraper 4 is tilted so that the soil above and below the scraper 4 can easily slide off. A small distance is maintained between the scraper 4 and the side wall of the pressing roller 2 to avoid contact and friction with the pressing roller 2.

[0033] The mud removal auxiliary component is driven by the pressing roller 2 to clean the mud on the scraper 4, so that the scraper 4 maintains a good mud scraping state and prevents wet mud from accumulating on the scraper 4.

[0034] The demudifier auxiliary part includes a demudifier rod 64 sleeved on the outside of the scraper 4, and the demudifier rod 64 is arranged to be tilted to match the scraper 4. The demudifier rod 64 is an oblique U-shape, and the opening of the demudifier rod 64 faces downward. When the demudifier rod 64 slides to one side of the pressure roller 2, it is convenient to remove the demudifier rod 64 obliquely above the scraper 4.

[0035] Specifically, the desilting auxiliary part also includes a connecting plate 63 fixedly connected to the upper end surface of the lower side of the desilting rod 64, a reciprocating screw rod 61 is rotatably connected to the inner side of the bottom end of the seed drill body 1, and a transmission block 65 is provided on the outer transmission sleeve of the reciprocating screw rod 61, and a horizontal transmission rod 66 is fixedly connected to the upper end of the transmission block 65, and the horizontal transmission rod 66 is connected to the connecting plate 63 through a transmission curved rod 62. The connecting plate 63 and the transmission curved rod 62 are detachably connected, and the connecting plate 63 and the transmission curved rod 62 are fixed by bolts. There is a spacing between the inner walls on both sides of the bottom end of the pressing roller 2 and the seed drill body 1, so that the desilting rod 64 can be easily removed after sliding to one side of the pressing roller 2. When the desilting rod 64 is worn, a new desilting rod 64 can be replaced according to demand, thereby ensuring the desilting effect of the desilting rod 64.

[0036] Furthermore, the bottom end of the seed drill body 1 is fixedly connected with a protective tube 3 which is arranged on the outside of the reciprocating screw rod 61. The upper end of the protective tube 3 is connected with a guide dust cover 5, and a through groove is provided on the side of the guide dust cover 5 away from the pressing roller 2. The transmission bent rod 62 passes through the through groove and is slidably connected in the through groove, which protects the reciprocating screw rod 61 and prevents the reciprocating screw rod 61 from being contaminated with mud and affecting the transmission of the transmission block 65.

[0037] Among them, a pair of transmission shafts 9 are rotatably connected to both side walls of the bottom end of the seed drill body 1, one pair of coaxial corresponding transmission shafts 9 are respectively fixedly connected to the two ends of the pressing roller 2, and the other pair of coaxial corresponding transmission shafts 9 are respectively fixedly connected to the two ends of the reciprocating screw 61. The side walls of the two transmission shafts 9 on one side are sleeved with pulleys, and the two pulleys are driven by a belt 8, and the reciprocating screw 61 is directly driven to rotate by the rotation of the guide dust cover 5, which is energy-saving and environmentally friendly. The side of the seed drill body 1 is connected to a protective shell 10 covered on the outside of the belt 8, which is used for dust prevention to prevent dust and dirt from being thrown onto the belt 8 and affecting the transmission.

[0038] The specific working principle is as follows: when the seed drill is running, the pressure roller 2 contacts the land with friction, so that the pressure roller 2 rotates with the drive of the seed drill body 1, and the soil after fertilization is initially flattened. By setting a scraper 4 on one side of the pressure roller 2, the scraper 4 will scrape off the soil on the outer surface of the pressure roller 2. Since the scraper 4 is set at an angle, even if a small amount of soil accumulates on the upper end surface of the scraper 4, it is easy to slide off. The pressure roller 2 rotates the transmission shafts 9 at both ends to rotate synchronously, and drives another pair of transmission shafts 9 to rotate through the belt and the belt 8, so that the reciprocating screw 61 rotates. When the reciprocating screw 61 rotates, the transmission block 65 on the outside thereof will reciprocate. The transmission block 65 reciprocates through the horizontal transmission rod 66 to drive the transmission bent rod 62 to reciprocate, and finally drives the mud removal rod 64 to slide back and forth on the outside of the scraper 4 through the connecting plate 63, scraping off the soil contaminated on both sides of the scraper 4, so that the scraper 4 maintains a good mud scraping state.

[0039] When the demudifier rod 64 is subject to severe wear, unscrew the bolt on the upper end of the transmission bent rod 62, and then slide the connecting plate 63 and the demudifier rod 64 to one side until the demudifier rod 64 moves to drive one side of the pressing roller 2 (there is a certain distance between the end of the pressing roller 2 and the inner wall of the seed drill body 1), so that the demudifier rod 64 and the connecting plate 63 can be removed to the inner side of the seed drill body 1, and the new demudifier rod 64 is mounted on the outer side of the scraper 4, and the connecting plate 63 is aligned with the end of the transmission bent rod 62, and the bolts are tightened to fix the transmission bent rod 62 and the connecting plate 63.

[0040] The above-mentioned specific embodiments are merely preferred embodiments of the present application. Based on the technical solutions of the present application and the relevant inspirations of the above-mentioned embodiments, those skilled in the art may make various alternative improvements and combinations to the above-mentioned specific embodiments. The above-mentioned specific embodiments are merely explanations of the present application, and they are not limitations of the present application.
