[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0029] Example 1:

[0030] See also Figures 1-3 , a rotary tiller for agricultural planting, comprising:

[0031] A mounting beam 1 is provided, on which a plurality of mounting brackets 2 are symmetrically fixed, wherein arc-shaped connecting rods 3 are rotatably mounted at the bottom ends of the mounting brackets 2, and a plowshare 4 is fixed at the bottom ends of the arc-shaped connecting rods 3;

[0032] The telescopic rod 5 has mounting heads 11 fixed at both ends. The upper mounting head 11 is rotatably connected to the top of the mounting frame 2, and the lower mounting head 11 is rotatably connected to the top wall of the arc-shaped connecting rod 3. A first spring 6 is sleeved on the outer side of the telescopic rod 5 and fixed between the two mounting heads 11.

[0033] The n-shaped frame 8 is fixedly connected to the mounting frame 2 through the connecting beam 7. A rotating shaft 9 is rotatably installed between the bottom of the inner wall of the n-shaped frame 8, and a plurality of rotary tillage components 10 are symmetrically installed on the rotating shaft 9.

[0034] The mounting beam 1 is connected to an external traction machine via a traction frame, and the rotating shaft 9 is connected to an external driving device.

[0035] In this embodiment, the mounting beam 1 is provided to facilitate the installation of the overall device, and the mounting beam 1 is connected to an external traction machine (such as a tractor) through a traction frame (not shown in the figure), which facilitates the operation of the device by the external traction machine. The arc-shaped connecting rod 3 is provided for mounting the plow head 4, and the extension rod 5 and the first spring 6 provided between the arc-shaped connecting rod 3 and the mounting frame 2 can protect the plow head 4. When the plow head 4 touches hard objects such as stones, the plow head 4 is compressed by the arc-shaped connecting rod 3 and the first spring 6 is squeezed, at which time the plow head 4 will be deflected backward until the plow head 4 passes through the stone position, at which time the plow head 4 is reset under the action of the first spring 6. The first spring 6 is a compression spring with a large elastic coefficient, and the force on the plow head 4 during normal plowing will not deform the first spring 6. The rotating shaft 9 is connected to an external driving device, which can drive the rotary tillage assembly 10 to work and perform rotary tillage operation. The external driving device can be a motor or other machinery. The rotary tillage assembly 10 can be shifted left and right on the rotating shaft 9 for a short distance, so when the rotary tillage assembly 10 touches hard objects such as stones, it will be deflected to one side under the force, thereby avoiding deformation and damage of the rotary tillage assembly 10 during rotation and improving the service life of the device.

[0036] Embodiment two:

[0037] Please refer to Figures 4-5 , the embodiment provides a technical scheme based on embodiment one:

[0038] The rotary tillage assembly 10 comprises a mounting block 101, and a sleeve ring 102 is fixed to the outer wall of the mounting block 101 through a connecting block 103.

[0039] The sleeve ring 102 is slidably sleeved on the outer wall of the rotating shaft 9, and the outer wall of the sleeve ring 102 is fixed with a mounting plate 104 through bolts.

[0040] The outer wall of the mounting plate 104 is fixed with an L-shaped rotary tillage cutter head 105.

[0041] The rotary tillage cutter heads 105 on the adjacent two mounting plates 104 are staggered.

[0042] The rotating shaft 9 comprises a shaft body 91, and an installation groove 92 is formed in the shaft body 91 corresponding to the position of the rotary tillage assembly 10.

[0043] An installation shaft 93 is fixed between the inner walls of the installation groove 92, and the mounting block 101 is slidably installed on the corresponding installation shaft 93. The mounting block 101 is fixedly connected to the side wall of the installation groove 92 through a second spring 94 on both sides.

[0046] In the embodiment, the rotary tillage assembly 10 can be offset left and right for a short distance on the rotating shaft 9, so that when the rotary tillage assembly 10 touches hard foreign matter such as stones, it will be offset to one side under force, thereby avoiding deformation and damage of the rotary tillage assembly 10 during rotation when touching stones, and improving the service life of the device. When the rotating shaft 9 drives the rotary tillage assembly 10 to work, when the rotary tillage bit 105 on the rotary tillage assembly 10 touches a stone, under the reaction force of the stone, the rotary tillage bit 105 will drive the mounting block 101 to slide in the mounting groove 92, so that the rotary tillage bit 105 passes over the stone, avoiding continuous collision and damage of the rotary tillage bit 105 with the stone. The second spring 94 can reset the rotary tillage bit 105 after offsetting, and the second spring 94 is a spring with a large elastic coefficient. During normal rotary tillage, the force on the rotary tillage bit 105 will not deform the second spring 94. At the same time, the rotary tillage bit 105 is fixed on the sleeve ring 102 through bolts, and can be replaced when it is damaged after long-term use.
