Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural machinery field especially, a kind of quick detachable rotary cultivator blade blade seat for rotary cultivator or ridger. BACKGROUND

[0002] In agricultural production, rotary cultivator and ridger are important operation equipment. However, there is a significant problem in most rotary cultivators and ridgers on the market at present, i.e., the rotary cultivation width is usually fixed and cannot be adjusted.

[0003] In actual operation process, when encountering farmland of different widths or needing diversified soil operation, such fixed-width design is very limited. For example, in some irregularly shaped farmland or areas needing local fine rotary cultivation, the rotary cultivation width cannot be adjusted according to actual demand, which will cause some areas to be unable to be effectively rotary cultivated, resulting in areas without rotary cultivation. This not only affects the overall operation effect of soil, such as uneven soil crushing and inconsistent flatness, but also can adversely affect subsequent planting, irrigation and other agricultural operations.

[0004] Moreover, the traditional blade seat structure lacks flexibility and convenience in adjusting rotary cultivation width, and is difficult to meet the requirements of modern diversified and precise operation.

[0005] In order to solve the problem of no rotary cultivation area after adjusting the width of blade shaft and improve soil operation quality and efficiency, it is urgent to provide a rotary cultivator blade seat that can be quickly detached and installed and adapt to different width adjustment requirements. UTILITY MODEL CONTENT

[0006] The utility model aims at providing a quick detachable rotary cultivator blade seat, which can solve the problem of no rotary cultivation area after adjusting the width of blade shaft and improve soil operation quality and efficiency.

[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0008] The utility model provides a quick detachable rotary cultivator blade seat, characterized in that it comprises a blade mounting seat, a polygonal clamping seat, a blade and a bolt. The blade mounting seat is used for mounting the blade and fastening the blade through the cooperation of the bolt and nut. The polygonal clamping seat is provided with a through hole and a threaded hole. Two pairs of polygonal clamping seats are buckled on a hexagonal shaft through the through hole and threaded hole and the cooperation of the bolt to realize the installation and fixation of the blade seat on the hexagonal shaft. The shape of the polygonal clamping seat includes but is not limited to the illustrated shape and can also be the shape composed of trapezoidal upper height and two sides. When the hexagonal shaft rotates, it drives the blade seat to rotate, thereby realizing rotary cultivation operation.

[0009] Preferably, the blade mounting seat is provided with a blade fixing bolt hole for cooperating with the bolt and nut to fix the blade.

[0010] Preferably, the quick-release rotary tillage blade seat is characterized in that the material is a cast part or a bent and welded part.

[0011] Compared with the existing processing mode, the quick-release rotary tillage blade seat has the beneficial effects that the problem that the rotary tillage width of the existing rotary tiller and ridger cannot be adjusted, resulting in that some areas cannot be rotary tilled, is effectively solved, the adaptability to different width farmlands is improved, the soil working effect is better, the convenient installation and dismounting mode is simple and quick to operate, the equipment downtime can be reduced, the work efficiency is improved and the labor intensity is reduced, the polygonal clamping seat shape is flexible and various, can adapt to various requirements and reduce the cost, various materials can be selected, the user can flexibly select according to the requirements and the budget, the product applicability and economy are enhanced, and the performance and working quality of the agricultural machinery are improved.
