Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples

Referring to fig. 1-4, a rotary blade convenient for blade replacement comprises a mounting cutter holder 1 and a rotary blade 2, wherein L-shaped mounting grooves 3 matched with the rotary blade 2 are formed in two sides of the mounting cutter holder 1, positioning grooves 4 penetrating through the rotary blade 2 are formed in two ends of one side of the mounting grooves 3, positioning columns 8 are slidably connected in the positioning grooves 4, limiting grooves 5 penetrating through the mounting cutter holder 1 and the rotary blade 2 are formed in the middle positions of the mounting grooves 3, limiting screws 9 are slidably connected in the limiting grooves 5, positioning plates 7 are connected to one ends of the positioning columns 8 and the limiting screws 9, and limiting nuts 10 are connected to the other ends of the limiting screws 9 in a threaded mode.

According to the rotary blade convenient for blade replacement, when the rotary blade 2 is required to be replaced, the limit nuts 10 are unscrewed, then the positioning plate 7, the positioning columns 8 and the limit screws 9 are removed, the old rotary blade 2 can be taken down, then the new rotary blade 2 is placed in the mounting groove 3, the positioning columns 8 are inserted into the positioning grooves 4, meanwhile, the limit screws 9 are inserted into the limit grooves 5, and then the limit nuts 10 are screwed, so that the rotary blade 2 can be replaced, the replacement process of the two rotary blades 2 is simpler and more convenient by screwing the two limit nuts 10, and in addition, the rotary blade structure in the utility model is similar to that disclosed in the patent application number CN202020341517.8, so that excessive description is omitted.

As shown in fig. 2, a placing groove 6 is formed in one side, close to the positioning plate 7, of the mounting tool apron 1, and the placing groove 6 is matched with the positioning plate 7. The locating plate 7 is placed in the placing groove 6, so that the side edge of the locating plate 7 is prevented from being impacted with broken stones during rotary tillage of the rotary cultivator, and the locating plate 7 is prevented from being damaged.

As shown in fig. 1 to 4, the positioning plate 7 is matched with the mounting groove 3. If the positioning plate 7 is not matched with the mounting groove 3, the positioning effect can be achieved, but the stress is uneven, and the positioning effect is poor.

As shown in fig. 4, a chamfer is provided on one side of the positioning plate 7 near the side where the tool holder 1 is mounted. The chamfer has a guiding function, and the positioning plate 7 is conveniently placed in the placing groove 6.

As shown in fig. 1, 2 and 4, the thickness of the positioning plate 7 is not greater than the depth of the placement groove 6. If the thickness of the positioning plate 7 is greater than the depth of the placement groove 6, the side edges of the positioning plate 7 easily protrude to contact other objects.

As shown in fig. 4, the end of the positioning post 8 and the end of the limiting screw 9, which are far away from the positioning plate 7, are arc-shaped. The positioning column 8 and the limiting screw 9 which are arranged in an arc shape are easier to insert into the positioning groove 4 and the limiting groove 5.

As shown in fig. 2, 3 and 4, the length of the positioning post 8 is greater than one half of the width of the mounting block 1, and the length of the positioning post 8 is less than the width of the mounting block 1. After the positioning column 8 is inserted into the installation tool apron 1, one end of the positioning column 8, which is far away from the positioning plate 7, can extend into the rotary tillage blade 2 or pass over the rotary tillage blade 2, so that the stability of the rotary tillage blade 2 is improved.
