[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a multi-blade head rotary weeding structure, including a bottom cover, a top cover and a bolt, the top cover is installed on the top of the bottom cover, the bolt is threadedly connected to the bottom of the bottom cover and extends to the inside of the top cover, and a disassembly device is provided inside the bottom cover and the top cover.

[0007] The disassembly device includes a spring, a button, a stop pin, a torsion spring and a blade. The lower end of the spring is installed at the bottom of the bottom cover, the button is fixedly installed at the top of the spring, the stop pin is rotatably connected to the inside of the bottom cover, the torsion spring is installed on the outside of the stop pin, and the blade is installed between the bottom cover and the top cover.

[0008] Preferably, a limiting groove is provided at the lower end of the interior of the top cover, and the stop pin is rotatably connected in the limiting groove. The stop pin is limited by the limiting groove so that the stop pin can rotate around the limiting groove.

[0009] Preferably, there are three disassembly devices, which are distributed at equal angles inside the bottom cover and the top cover. The stop pin and the button are located on the same straight line, and the button is located on the side close to the center of the bottom cover. The button limits the blade to prevent it from moving close to the center of the top cover.

[0010] Preferably, a locking hole is provided inside one end of the blade, and a mounting groove is provided inside the top cover, and the mounting groove is connected to the middle of the top cover. When installing the blade, press the button downward and insert the blade into the mounting groove. At the same time, one end of the blade squeezes the stop pin to rotate downward. When the locking hole position of the blade exceeds the stop pin, the blade is pulled outward. At the same time, under the action of the torsion spring, the stop pin is driven to reset and engage with the locking hole provided on the blade to achieve the installation of the blade.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The multi-blade rotary weeding structure is equipped with a disassembly device. When the blade needs to be installed, press the button down, insert the blade into the installation slot, and push the blade into the installation slot. At the same time, one end of the blade squeezes the stop pin to rotate the stop pin downward. When the position of the blade's clamping hole exceeds the stop pin, pull the blade outward. At the same time, under the action of the torsion spring, the stop pin is driven to reset and engage with the clamping hole opened on the blade, thereby realizing the installation of the blade and easy operation.

[0013] 2. The multi-blade rotating weeding structure is equipped with a disassembly device. When the blade needs to be disassembled, press the button down, push the blade toward the inside of the top cover, and then pull the blade out from the middle position of the top cover to achieve disassembly of the blade.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0022] Embodiment 1: A multi-blade rotary weeding structure includes a bottom cover 1, a top cover 2 and a bolt 3. The top cover 2 is installed on the top of the bottom cover 1. A limiting groove 5 is provided at the lower end of the top cover 2. The stop pin 403 is rotatably connected in the limiting groove 5. The stop pin 403 is limited by the limiting groove 5 so that the stop pin 403 can rotate around the limiting groove 5. The bolt 3 is threadedly connected to the bottom of the bottom cover 1 and extends to the inside of the top cover 2. A disassembly device is provided inside the bottom cover 1 and the top cover 2. There are three disassembly devices, which are distributed at equal angles inside the bottom cover 1 and the top cover 2. The stop pin 403 and the button 402 are located on the same straight line, and the button 402 is located on the side close to the center of the bottom cover 1. The blade 405 is limited by the button 402 to prevent the blade 405 from moving close to the center of the top cover 2.

[0023] The disassembly device includes a spring 401, a button 402, a stop pin 403, a torsion spring 404 and a blade 405. The lower end of the spring 401 is installed at the bottom of the bottom cover 1, and the button 402 is fixedly installed on the top of the spring 401. The button 402 limits the blade 405 to prevent the blade 405 from moving toward the center of the top cover 2. The stop pin 403 is rotatably connected to the inside of the bottom cover 1. The stop pin 403 is engaged with the card hole opened by the blade 405 to achieve the installation and fixation of the blade 405. The torsion spring 404 is installed on the outside of the stop pin 403. The blade 405 is installed between the bottom cover 1 and the top cover 2. When the blade 405 is installed, the button 402 is pressed downward, and the blade 405 is inserted into the installation slot. At the same time, one end of the blade 405 squeezes the stop pin 403 to rotate the stop pin 403 downward. When the position of the hole of the blade 405 exceeds the stop pin 403, the blade 405 is pulled outward. At the same time, under the action of the torsion spring 404, the stop pin 403 is driven to reset and engage with the hole of the blade 405, thereby realizing the installation of the blade 405.

[0024] When in use, when the blade 405 needs to be installed, the button 402 is pressed downward, and the blade 405 is inserted into the installation slot and pushed into the installation slot. At the same time, one end of the blade 405 squeezes the stop pin 403, causing the stop pin 403 to rotate downward. When the card hole position of the blade 405 exceeds the stop pin 403, the blade 405 is pulled outward. At the same time, under the action of the torsion spring 404, the stop pin 403 is driven to reset and engage with the card hole opened on the blade 405 to achieve the installation of the blade 405. When the blade 405 needs to be disassembled, the button 402 is pressed downward, and the blade 405 is pushed toward the inside of the top cover 2, and then the blade 405 is pulled out from the middle position of the top cover 2 to achieve the disassembly of the blade 405.
