Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of agricultural equipment, and particularly relates to a ridging device and rotary tillage ridging machine. TECHNICAL BACKGROUND

[0002] The rotary tillage ridging machine is a working machine driven by the power output shaft of a tractor. It uses the rotary motion of the blades on the rotary tillage machine shaft and the compound motion of the machine advancing to perform rotary tillage and ridging operations on uncultivated land and plowed fields. The working environment in the field is harsh, and the transmission mechanism is easy to get stuck. The ordinary ridging device adopts single shaft transmission. Since the ridging shaping roller is a high-speed rotating work component, once the transmission mechanism is stuck, the torque borne by the transmission mechanism will increase sharply, which not only causes unnecessary wear of the transmission mechanism, greatly reduces the service life of the transmission mechanism, and even causes damage to the transmission mechanism. Replacing the transmission mechanism requires disassembling the transmission box, which is very time-consuming and easy to delay agricultural harvesting, and will greatly increase the maintenance cost. Moreover, when the transmission system is temporarily stuck, the ridging device will vibrate violently, affecting the working stability of the ridging device. In summary, how to solve the problem of the increase of maintenance cost caused by the delay of ridging operation and the complex maintenance caused by the foreign matter entering the transmission chain leading to the chain sticking and shaft breaking has become a problem to be solved by the technical personnel in the field.

[0003] For example, a new ridging machine with publication number CN202223083771.0, comprising a main frame, a first transfer case is connected to the upper end of the rear side of the main frame through bolts, a first universal transmission shaft is connected to the front end of the output shaft of the first transfer case, a second transfer case is connected to the left end of the first universal transmission shaft, a shaping roller is installed at the rear end of the main frame, the shaping roller is rotatably connected to the main frame, a third transfer case is connected to the left end of the shaping roller, a second universal transmission shaft is installed between the third transfer case and the second transfer case, a plurality of shaping wheels are installed on the shaping roller, and the soil is collected by the soil collecting disc once, and then collected by the ridging shovel twice. Although the existing technology has a ridging operation, the height and width of the ridge can meet the use requirements, but when the transmission mechanism is stuck, the single shaft transmission adopted by the existing technology will cause the shaft to be twisted and broken by the instantaneous high load, which not only increases the cost of part maintenance, but also reduces the working efficiency of the rotary tillage ridging.
