According to the connection form between the scarifier and the tractor, there are two types: towed type and hanging type. The traction provided by the tractor and the weight of the scarifier are used to make the rake teeth cut into the soil, loosen the hard soil, and leave a loose soil zone after the machine passes. It is often used for pre-scarring operations before bulldozers or scrapers operate. Compared with traditional drilling and blasting construction methods, it has the advantages of simplified construction process, fewer construction machines and tools, high productivity, and good production safety.

[0024] In a specific embodiment of the utility model, the blade of the agricultural tiller that is easy to disassemble and assemble is used to install the disassembly component 5 and the cutting blade 6 at the bottom of the disassembly component 5 in the mounting ring 3 through the mounting hole 4. The user can directly disassemble the disassembly component 5 according to its own structure in daily use, and conveniently disassemble the cutting blade 6 for cleaning or grinding, which can help increase the overall tilling effect and service life of the agricultural tiller, and further improve the efficiency of the agricultural tiller at work.

[0025] Specifically, the disassembly assembly 5 includes a protective shell 501, a push rod 502, a button protective shell 503, a connecting button 504, a first return spring 505, a pressure plate 506, a first fixed groove 507, a connecting rod 508, an elastic block 509, a second fixed groove 510, a second return spring 511 and a connecting mounting rod 512. Multiple protective shells 501 are arranged on one side of the mounting hole 4, and multiple push rods 502 are sleeved inside the multiple protective shells 501.

[0026] In a specific embodiment of the present invention, the disassembly component 5 fixes the cutting blade 6 as a whole through the protective shell 501, and the push rod 502 can be used to adjust the structural position inside the disassembly component 5, thereby providing an operational basis for the disassembly of the disassembly component 5 itself.

[0027] Specifically, multiple button protective shells 503 are fixedly connected to the tops of multiple protective shells 501, multiple connecting buttons 504 are sleeved inside the multiple button protective shells 503, multiple first return springs 505 are fixedly connected to the bottoms of multiple connecting buttons 504, multiple pressure plates 506 are fixedly connected to the bottoms of multiple connecting buttons 504, and multiple first fixing grooves 507 are opened at the tops of the inner walls of the multiple protective shells 501.

[0028] In a specific embodiment of the present invention, the button shell 503 can provide external protection and limitation for the connection button 504 to prevent the connection button 504 from being displaced, and the connection button 504 will drive the first reset spring 505 to rebound downward, thereby achieving a reset effect. However, at the moment when the connection button 504 moves downward, the pressure plate 506 fixed at its bottom will also directly move downward to complete the operation, so as to move the elastic block 509 inside the first fixed groove 507 out, thereby achieving the effect of internal movement of the disassembly component 5.

[0029] Specifically, multiple connecting rods 508 are fixedly connected to the backs of multiple push rods 502, multiple elastic blocks 509 are fixedly connected to the tops of multiple connecting rods 508, multiple second fixed grooves 510 are opened on the tops of the inner walls of multiple protective shells 501, and the elastic blocks 509 match the second fixed grooves 510 and the first fixed grooves 507.

[0030] In a specific embodiment of the present invention, the connecting rod 508 is fixed to the back of the push rod 502. When the push rod 502 moves backward, the connecting rod 508 will also move backward, and the elastic block 509 fixed on the top of the connecting rod 508 will also withdraw from the second fixing groove 510 until it is stuck in the first fixing groove 507. At this time, the disassembly component 5 will be fixed as a whole due to the structure of the first fixing groove 507.

[0031] Specifically, the plurality of second return springs 511 are fixedly connected to the backs of the plurality of connecting rods 508 , the plurality of connecting mounting rods 512 are fixedly connected to the backs of the plurality of connecting rods 508 , and the second return springs 511 match the connecting rods 508 .

[0032] In a specific embodiment of the present invention, the second return spring 511 will compress itself after the connecting rod 508 moves backward. At this time, the connecting mounting rod 512 fixed on the back of the connecting rod 508 will extend out and be stuck in the mounting hole 4, helping the cutting blade 6 to be installed as a whole inside the mounting hole 4. When disassembly is required, only the connection button 504 needs to be pressed down to press the elastic block 509 stuck in the first fixed groove 507. At this time, without the resistance of the elastic block 509, the second return spring 511 will continue to exert force to reset the push rod 502, thereby helping the connecting mounting rod 512 to withdraw and achieve the disassembly effect. The user can take out the disassembled cutting blade 6 for grinding and maintenance, further improving the overall service life and work efficiency of the device.

[0033] Specifically, a soil loosening notch 8 is formed on the top of each of the plurality of cutting blades 6 .

[0034] In a specific embodiment of the present invention, the loosening notch 8 can absorb soil in a wider range by utilizing the groove during the operation of the cutting blade 6, thereby further improving the overall functionality of the device.

[0035] Specifically, both sides of the plurality of cutting blades 6 are fixedly connected with loosening nail blocks 9 .

[0036] In a specific embodiment of the present invention, the loosening nail block 9 can loosen the soil within the range of the cutting blade 6 during operation, thereby further improving the functionality of the device.

[0037] Working principle: The blade of this kind of agricultural tiller that is easy to disassemble and assemble is used to install the disassembly component 5 and the cutting blade 6 at the bottom of the disassembly component 5 in the mounting ring 3 through the mounting hole 4. The user can directly disassemble the disassembly component 5 according to its own structure in daily use, and it is convenient to disassemble, clean or grind the cutting blade 6, which can help increase the overall tilling effect and service life of the agricultural tiller, and further improve the efficiency of the agricultural tiller at work. The disassembly component 5 fixes the cutting blade 6 as a whole through the protective shell 501, and the push rod 502 can be used to adjust the structural position inside the disassembly component 5, so as to To provide an operational basis for the disassembly of the disassembly component 5 itself, the button shield 503 can provide external protection and limit for the connection button 504 to prevent the connection button 504 from being displaced, and the connection button 504 will drive the first return spring 505 to rebound downward to achieve the reset effect, but at the moment when the connection button 504 moves downward, the pressure plate 506 fixed at its bottom will also directly move downward to complete the operation, so that the elastic block 509 in the first fixing groove 507 is moved out, so as to achieve the effect of internal activity of the disassembly component 5, and the connecting rod 508 is fixed to the back of the push rod 502. When the push rod 502 moves backward, the connecting rod 50 8 will also move backward, so that the elastic block 509 fixed on the top of the connecting rod 508 will also withdraw from the second fixing groove 510 until it is stuck in the first fixing groove 507. At this time, the disassembly component 5 will be fixed as a whole due to the structure of the first fixing groove 507, and the second return spring 511 will compress itself after the connecting rod 508 moves backward. At this time, the connecting installation rod 512 fixed on the back of the connecting rod 508 will extend out and be stuck in the installation hole 4, helping the cutting blade 6 to be installed as a whole in the installation hole 4. When disassembly is required, only the connection button 504 needs to be pressed to press the elastic block 509 stuck in the first fixing groove 507 downward. At this time, without the resistance of the elastic block 509, the second reset spring 511 will continue to exert force to reset the push rod 502, thereby helping the connecting mounting rod 512 to withdraw and achieve the disassembly effect. The user can take out the disassembled cutting blade 6 for grinding and maintenance, thereby further improving the overall service life and work efficiency of the device. The loosening notch 8 can utilize the groove to absorb the soil within a wider range during the operation of the cutting blade 6, thereby further improving the overall functionality of the device. The loosening nail block 9 can loosen the soil within the range of the cutting blade 6 during operation, thereby further improving the functionality of the device.
