DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application. EMBODIMENT

[0038] As Figures 1-12As shown, the embodiment of the present application provides a rotary tillage and fertilization seeder wheel compactor, which comprises a compaction assembly 1, a scraping assembly 2, a seeding and tillage assembly 3, a rotary tiller 4 and a fertilization assembly 5. The rotary tiller 4 comprises a frame 401, and the side connected with a tractor is set as the front side. The fertilization assembly 5 is arranged on the top of the frame 401. The seeding and tillage assembly 3 is rotatably arranged on the rear side of the frame 401. The compaction assembly 1 is rotatably arranged on the rear side of the seeding and tillage assembly 3. The scraping assembly 2 is arranged on the rear side of the compaction assembly 1.

[0039] In this embodiment, referring to Figures 3-4 , the compaction assembly 1 comprises a first mounting frame 101. A first guide rail 102 is arranged above the front side of the first mounting frame 101. A first sliding bar 103 is slidably connected inside the first guide rail 102. A plurality of first connecting plates 104 are arranged at intervals on the front side of the first sliding bar 103. A second sliding rail 105 is arranged above the rear side of the first mounting frame 101. A second sliding bar 106 is slidably connected inside the second sliding rail 105. A plurality of second connecting plates 107 are arranged at intervals on the rear side of the second sliding bar 106.

[0040] In this embodiment, referring to Figures 4-6 , the compaction assembly 1 further comprises a first main shaft 114 rotatably connected below the inside of the first mounting frame 101. A plurality of central ring plates 115 are sleeved at intervals on the outside of the first main shaft 114. An outer sleeve tube 116 is arranged on the outside of each of the central ring plates 115. A first inner sleeve tube 118 is embedded on one side inside the outer sleeve tube 116. An inner compaction wheel 117 is arranged on the outside of the first inner sleeve tube 118. A first conical cover 119 is arranged on one side edge of the inner compaction wheel 117. A first shaft sleeve 120 is arranged at the center of the first conical cover 119. The inner hole of the first shaft sleeve 120 is correspondingly sleeved on the outside of the first main shaft 114. A second inner sleeve tube 122 is embedded on the other side inside the outer sleeve tube 116. An outer compaction wheel 121 is arranged on the outside of the second inner sleeve tube 122. The outer compaction wheel 121 is respectively sleeved and matched on the outside of the inner compaction wheel 117. A second conical cover 123 is arranged on one side edge of the outer compaction wheel 121. A second shaft sleeve 124 is arranged at the center of the second conical cover 123. The inner hole of the second shaft sleeve 124 is correspondingly sleeved on the outside of the first main shaft 114.

[0041] In this embodiment, the inner press wheel 117, the first cone cover 119 and the outer press wheel 121, the second cone cover 123 form a press wheel, which slides along the axial direction of the first main shaft 114 through the first shaft sleeve 120, and then moves the inner press wheel 117 through the first cone cover 119. When moving, the first inner sleeve 118 will move synchronously inside the outer sleeve 116, and the movement of the inner press wheel 117 will be more stable under the limiting of the outer sleeve 116. The above can make the inner press wheel 117 and the first cone cover 119 move along the axial direction of the first main shaft 114, so as to change the distance between the outer press wheel 121 and the inner press wheel 117, and then change the width of the press wheel on the side of the inner press wheel 117. Similarly, by controlling the second shaft sleeve 124 to slide along the axial direction of the first main shaft 114, the width of the press wheel on the side of the outer press wheel 121 can be changed. In summary, if the inner press wheel 117, the first cone cover 119 and the outer press wheel 121, the second cone cover 123 are controlled to move to one side along the axial direction of the first main shaft 114, the press wheel can be collectively offset to that side, and vice versa. When the inner press wheel 117, the first cone cover 119 and the outer press wheel 121, the second cone cover 123 are controlled to move relatively, the wheel width of the press wheel can be controlled to adapt to various pressing requirements.
