Description

Technical Field

[0001] The utility model relates to the technical field of rotary tillers, in particular to a rotary tiller structure. Background Art

[0002] Rotary tillers are tilling machines that work with tractors to complete ploughing and harrowing operations. They are widely used because of their strong soil crushing ability and flat surface after ploughing. At the same time, they can cut up the root stubble buried below the surface, which is convenient for seed drills and provides a good seed bed for later sowing. Rotary tillers have the functions of breaking the plow bottom layer, restoring the soil tillage layer structure, improving the soil's ability to store water and retain moisture, eliminating some weeds, reducing pests and diseases, leveling the surface, and improving the standard of agricultural mechanization operations.

[0003] According to the search, the Chinese patent document, announcement number: CN210298436U, discloses a detachable agricultural rotary tiller, each set of rotary blade seats are sequentially engaged along the direction of the limit groove of the rotating seat body, and then the multiple sets of rotary blade seats are fixed to the rotating seat body through a locking ring. When one set of rotary blade seats is damaged, it can be disassembled and replaced at any time, reducing the maintenance time and cycle of the equipment, and also improving the efficiency of tilling the land. However, there are still certain problems with this device: if the middle rotary blade seat is damaged, all the rotary blade seats on one side must be disassembled, which is very difficult to disassemble. At the same time, when disassembling, it is necessary to first unscrew the threaded connection of the locking ring, which makes it inconvenient to disassemble. Both of them will lead to low efficiency during replacement and disassembly. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the shortcomings of the prior art, the utility model provides a rotary tiller structure, which has the feature that a fixing sleeve can be removed by pressing a pressing block, thereby facilitating the disassembly of a rotating blade seat. At the same time, a single blade body can be replaced by turning a bolt, further improving the efficiency of replacement and disassembly, and solving the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rotary tiller structure, including a rotating seat body, a notch is provided at one end of the rotating seat body, a spring and a pressing block are arranged inside the notch, a sliding bar is fixedly connected to the outer surface of the pressing block, and a plurality of first circular grooves are equidistantly provided on the outer surface of the pressing block, a plurality of second circular grooves are equidistantly provided on the outer surface of the rotating seat body near one end of the notch, a positioning ball is arranged inside the second circular groove, a fixed sleeve is sleeved at one end of the rotating seat body, a plurality of positioning grooves are equidistantly provided on the inner wall of the fixed sleeve, a movable groove is provided on the outer surface of the rotating seat body, and a rotating knife seat is sleeved on the outer surface of the rotating seat body, a knife body is arranged on the outer surface of the rotating knife seat, and a fixing plate is fixedly connected to the lower end of the knife body.

[0010] Preferably, a sliding groove is provided on the inner wall of the notch, and the sliding groove is slidably connected to the sliding bar.

[0011] Through the above technical solution, the sliding bar is set on the outer surface of the pressing block, and the number of the sliding bars is equal to the number of the sliding grooves. At the same time, the pressing block is slidably connected to the sliding groove on the inner wall of the slot through the sliding bar, that is, when the pressing block is pressed, the pressing block can move inside the track of the sliding groove.

[0012] Preferably, the positioning groove is snap-fitted with the positioning ball.

[0013] Through the above technical solution, when the pressing block is pressed inwardly, the pressing block slides along the slide bar inside the slide groove, and at the same time, the pressing block is subjected to force by the extrusion spring. When the pressing block moves to the inner wall close to the slot, its positioning ball falls into the inside of the first circular groove, that is, the positioning ball is disengaged from the positioning groove, so that the fixing sleeve can be easily removed, which facilitates the replacement of the rotating tool holder and improves the efficiency of replacement.

[0014] Preferably, a sliding block is fixedly connected to the inner wall of the rotating knife seat, and the rotating knife seat is slidably connected to the movable groove via the sliding block.

[0016] Preferably, bolts are provided between the fixing plate and the rotating tool holder.

[0017] Through the above technical solution, through the threaded connection between the tool body and the rotating tool holder, when one tool body is damaged, the single tool body can be replaced by turning the bolt, which further improves the replacement efficiency.

[0018] Compared with the prior art, the utility model provides a rotary tiller structure, which has the following beneficial effects:

[0019] 1. The utility model provides a positioning ball and a positioning groove and other components. When the pressing block is pressed inwardly, the pressing block slides along the slide bar inside the slide groove. At the same time, the pressing block is subjected to force by the extrusion spring. When the pressing block moves to the inner wall close to the groove, the positioning ball falls into the first circular groove, that is, the positioning ball is disengaged from the snap-fitting with the positioning groove. In this way, the fixing sleeve can be easily removed by simply pressing the pressing block, which facilitates the replacement of the rotating tool holder and improves the efficiency of replacement and disassembly.

[0020] 2. The utility model provides a knife body, and the fixing plate at the lower end of the knife body and the rotating knife seat are fixed and installed by bolts, so that when a knife body is damaged, the single knife body can be replaced by turning the bolt, which further improves the efficiency of replacement and disassembly.
