Description
Technical Field
The utility model belongs to the technical field of the rotary cultivator technique and specifically relates to indicate that rotary cultivator is used prevents pressing from both sides grass device.
Background
The rotary cultivator is a cultivator which is matched with a tractor to complete the operations of ploughing and harrowing. The soil breaking machine has the characteristics of strong soil breaking capacity, flat ground surface after ploughing and the like, so that the soil breaking machine is widely applied; meanwhile, the stubble buried under the ground surface can be cut up, the operation of the seeder is convenient, and a good seedbed is provided for later-period seeding; however, when the existing rotary cultivator works, the weeds on the ground are easily wound at the joint of the rotary tillage shaft and the driven bearing seat and the reduction gearbox assembly and need to be cleaned frequently, so that the working efficiency is greatly reduced.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art, and provides a grass clamping prevention device which is reasonable in structure and good in grass clamping prevention effect and is used for a rotary cultivator.
In order to achieve the above object, the present invention provides a technical solution: the grass clamping prevention device for the rotary cultivator comprises a rack, wherein a reduction gearbox assembly is arranged at the center of the bottom of the rack, rotary cultivation shafts are arranged on the rack on two sides of the reduction gearbox assembly, one end part of each rotary cultivation shaft is connected with the rack through a driven bearing seat, the other end of each rotary cultivation shaft is connected with an output shaft flange, the output shaft flange is connected with an output shaft of the reduction gearbox assembly, and grass clamping prevention components are arranged at the connection parts of the rotary cultivation shafts, the driven bearing seats and the reduction gearbox assembly; the grass clamping prevention component comprises an inner barrel and an outer barrel, wherein one end of the outer barrel is fixed on the reduction gearbox assembly or the driven bearing seat, the other end of the outer barrel is opposite to the rotary tillage shaft, one end of the inner barrel is fixed on the rotary tillage shaft through an end plate, and the other end of the inner barrel is movably sleeved in the corresponding outer barrel.
The end plate of inner tube expand and form annular tip limiting plate, tip limiting plate inner ring is connected fixedly with rotary tillage axle outer peripheral face.
And a 1-5cm lap joint area is reserved at the sleeving part of the outer cylinder and the inner cylinder.
By adopting the above technical scheme, the utility model, the registrate through urceolus, inner tube forms the overlap area to prevent debris such as grass bits winding in the junction of rotary tillage axle and driven bearing frame, reducing gear box assembly, thereby effectively guarantee the normal operation of rotary tillage axle, prevent the emergence of pressing from both sides grass, rational in infrastructure after this scheme of adoption, prevent that it is effectual to press from both sides grass.
