[0021] The following further describes the utility model with reference to the drawings and embodiments.

[0022] An embodiment of the utility model provides a tool structure for an agricultural rotary tiller that is convenient for disassembly and assembly. As Figures 1-3 shown, it includes a transmission box 1 and a tool structure 6. The tool structure 6 has a detachable function. The side of the transmission box 1 is fixedly welded to the top plate 2, and the top plate 2 is used to prevent the broken soil from being thrown out.

[0023] As shown Figures 1-3 in the figure, the side surface of the top plate 2 is fixedly welded to the side plate 3. The side plate 3 is used to position the transmission shaft 5. The internal gear of the transmission box 1 is drivingly connected to the transmission shaft 5. The transmission shaft 5 is used for the power output of the transmission box 1. A tool structure 6 for tilling the land is connected to the transmission shaft 5. The tool structure 6 outputs power to the transmission box 1 through power components such as an internal combustion engine. The transmission box 1 transmits the power to the tool structure 6 and rotates it. During the rotation process, the soil can be plowed.

[0024] As shown Figures 1-3 in the figure, both ends of the transmission shaft 5 are connected to the bearing cover 4 through bearings. The transmission shaft 5 is connected to the bearing cover 4 through bearings, which can effectively and stably rotate the transmission shaft 5. The internal gear of the transmission box 1 is drivingly connected to a transmission rod 7, and the transmission rod 7 can be connected to power equipment such as an internal combustion engine.

[0025] Furthermore, as shown Figures 1-3 in the figure, the tool structure 6 includes a sleeve 601, a connecting portion 602, a placement slot 603, a tool handle 604, a tool bit 605, a fixing bolt 606, a fixing nut 607, and a positioning bolt 608. The outer surface of the transmission shaft 5 is sleeved with the sleeve 601, which enables disassembly between the sleeve 601 and the transmission shaft 5. The positioning bolt 608 penetrates through the sleeve 601 and is threadedly connected to the transmission shaft 5. The positioning bolt 608 is used to fix the transmission shaft 5 and the sleeve 601, facilitating the fixation between the sleeve 601 and the transmission shaft 5. A placement slot 603 is provided on the side surface of the connecting portion 602. The tool handle 604 is placed inside the placement slot 603. The placement slot 603 is used to connect the end of the tool handle 604. The fixing bolt 606 penetrates through the connecting portion 602 and the tool handle 604 and is threadedly fixed to the fixing nut 607. Tightening the fixing bolt 606 and the fixing nut 607 can fix the connecting portion 602 and the tool handle 604. The end of the tool handle 604 and the tool bit 605 are integrally formed. The integrally formed tool handle 604 and tool bit 605 can effectively improve their own strength and reduce the weakening of strength caused by welding.

[0026] Furthermore, as shown Figures 1-3 in the figure, the placement slot 603 is adapted to the end of the tool handle 604 away from the tool bit 605. The side slot of the placement slot 603 is adapted to the tool handle 604 and is not prone to shaking, which can effectively improve the connection stability of the tool.

[0027] Furthermore, as shown Figures 1-3 in the figure, the contact part between the placement slot 603 and the tool handle 604 can limit the movement of the tool handle 604. The placement slot 603 is in close fit with the tool handle 604, which can effectively reduce the problem of connection shaking between the connecting portion 602 and the tool handle 604.

[0028] Furthermore, as shown Figures 1-3As shown, the shape of the cutter head 605 is an arc design. The arc-shaped cutter head 605 can effectively contact the soil. The arc design can increase the contact area with the soil and improve the tillage efficiency.

[0029] Furthermore, as Figures 1-3 shown, the connecting part 602 and the sleeve 601 are connected by welding, which can effectively facilitate the processing between the sleeve 601 and the connecting part 602.

[0030] Working principle: When the tool needs to be disassembled and assembled, the sleeve 601 is sleeved outside the transmission shaft 5 to facilitate the disassembly and assembly between the transmission shaft 5 and the sleeve 601. The sleeve 601 and the transmission shaft 5 are fixed by the positioning bolt 608. When the tool needs to be disassembled and assembled, the tool handle 604 is placed inside the placement slot 603 on the connecting part 602 and the fixing bolt 606 is tightened to install the tool. When disassembly is required, only the fixing bolt 606 needs to be disassembled.
