Description

Technical Field

[0001] The utility model relates to the technical field of rotary tiller equipment, in particular to a rotary tiller cover plate structure. Background Art

[0002] A rotary tiller is a tilling machine that is used in conjunction with a tractor to complete plowing and harrowing operations. It is widely used because of its strong soil crushing ability and flat surface after plowing. It can also cut up the root stubble buried below the surface, facilitating the operation of the seeder and providing a good seed bed for later sowing.

[0003] The rotary tiller cover is an important part of the rotary tiller. It can protect the internal structure of the rotary tiller, and at the same time, it can limit the stirred soil within the moving space, ensuring that the surface is soft and flat after rotary tillage, and can also prevent a large amount of dust from being generated when the rotary tiller is working. At present, the rotary tiller cover generally only has a rotating function, which is convenient for later maintenance of the internal structure. However, the rotary tiller itself can be used for both dry land and wet land work. The soil turning space required for these two working states is not quite the same. Therefore, the current cover with only a single rotating function cannot take into account the turning space adjustment needs for both dry and wet land. Utility Model Content

[0018] The rotating assembly includes a bridge-type pull plate seat 3 hinged to the left bracket 1 through a hinge 2, and the other end of the pull plate seat 3 is movably mounted on the right bracket 1 and locked and limited by a limiting mechanism arranged on the right bracket 1.

[0019] The limiting mechanism includes a mounting frame 13 installed on the right side bracket 1, a movable bolt 14 is installed in the middle of the mounting frame 13, a support 16 is arranged at the bottom of the right end of the pull plate seat 3, a U-shaped groove is opened at the end of the support 16 for the movable bolt 14 to pass through, and an adjusting hand wheel 15 is installed on the movable bolt 14 located above the support 16, which can adjust the state of the pull plate seat 3 so as to better realize the adjustment of the lifting state and the rotation state of the rotary tiller cover 6.

[0020] When the adjusting hand wheel 15 is tightened, the adjusting hand wheel 15 limits the pull plate seat 3 to ensure the stability of the lifting assembly in the process of driving the rotary tiller cover plate to move.

[0021] When the adjusting hand wheel 15 is loosened, the limit of the pull plate seat 3 by the adjusting hand wheel 15 is loosened by rotating the movable bolt 14 outward, so that the pull plate seat 3 can drive the rotary tiller cover plate 6 to rotate, which is convenient for maintenance of the internal structure.

[0022] The lifting assembly includes a lifting upper seat 4 mounted on the pull plate seat 3 through a connecting plate 17 and a lifting lower seat 5 connected to the rotary tiller cover plate 6 through a bolt assembly.

[0023] The upper lifting seat 4 and the lower lifting seat 5 are both U-shaped, and fixed shafts 7 are respectively installed between the two side plates at the right ends of the upper lifting seat 4 and the lower lifting seat 5. Notches 11 are respectively opened on the left end side plates of the upper lifting seat 4 and the lower lifting seat 5, and movable shafts 12 are respectively slidably arranged in the upper and lower groups of notches 11.

[0024] A lifting frame for driving the rotary tiller cover plate 6 to lift up and down is installed between the lifting upper seat 4 and the lifting lower seat 5, and the lifting frame is hinged to the two movable shafts 12 and the two fixed shafts 7 respectively.

[0025] The lifting frame includes two lifting arms 10 cross-hinged in an X shape, the right sides of the two lifting arms 10 are respectively hinged to the fixed shafts 7 on the lifting upper seat 4 and the lifting lower seat 5, and the left sides of the lifting arms 10 are respectively hinged to the moving shafts 12 on the lifting upper seat 4 and the lifting lower seat 5.

[0026] A driving mechanism for driving the moving shaft 12 to drive the lifting frame to rise and fall is installed on the lifting seat 4. The driving mechanism includes an adjusting bolt 9 that passes through the middle of the fixed shaft 7 at the right end of the lifting seat 4. A butterfly nut 8 that is easy to operate is arranged on the right side of the adjusting bolt 9. The movement of the adjusting bolt is achieved by screwing the butterfly nut 8. The other end of the adjusting bolt 9 is threadedly connected to a threaded hole opened in the middle of the moving shaft 12 at the left end of the lifting seat 4, which can drive the moving shaft 12 to move axially along the adjusting bolt to achieve the lifting and lowering of the rotary tiller cover 6.

[0027] When the adjusting bolt 9 is rotated, the moving shaft 12 threadedly mounted with the adjusting bolt 9 will move along the axial direction of the adjusting bolt. At the same time, the lifting arm 10 hinged to the upper moving shaft 12 cooperates with another lifting arm 10 to push the lifting lower seat 5 to achieve lifting and lowering, and drive the rotary tiller cover 6 to move up and down to achieve the adjustment of the soil turning space.
