[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] To solve the technical problem of how to adjust the height of the blades of a rotary tiller, please refer to Figure 1 - Figure 2 , the following technical solutions are provided in this embodiment:

[0024] A rotary tilling mechanism convenient for cleaning the blades includes a fixed frame 1 and a lifting frame 2. The fixed frame 1 is slidably connected to the lifting frame 2. A connecting ear plate 14 is welded at the connection of the fixed frame 1 and the rotary tiller. A hydraulic cylinder 21 is fixedly installed at the upper end of the fixed frame 1. The output end of the hydraulic cylinder 21 penetrates the fixed frame 1 and is connected to the lifting frame 2. A cutter shaft 23 is movably installed at the bottom of the lifting frame 2. Cutter discs 24 are equidistantly welded on the cutter shaft 23. Blades 25 are detachably connected in a circular array on the cutter discs 24. One end of the cutter shaft 23 is fixedly connected to a motor 26.

[0025] Specifically, when it is necessary to adjust the height of the blades 25, start the hydraulic cylinder 21. The hydraulic cylinder 21 drives the lifting frame 2 to move up and down. Until the depth of the blades 25 inserted into the soil is appropriate, turn off the hydraulic cylinder 21. Then start the motor 26. The motor 26 drives the cutter shaft 23 to rotate. The cutter shaft 23 drives the cutter discs 24 fixedly connected thereto to rotate. The cutter discs 24 then drive the blades 25 fixedly connected thereto to rotate, realizing the tilling of the soil.

[0026] Among them, the connecting ear plate 14 is provided to facilitate the connection of the rotary tilling mechanism to the rotary tiller. The advantage of setting the blades 25 in a detachable connection is that the damaged blades 25 can be replaced.

[0027] To solve the technical problem of how to clean the blades of a rotary tiller, please refer to Figure 3 - Figure 5 , the following technical solutions are provided in this embodiment:

[0028] A water-absorbing sponge 13 is installed at the lower end of the fixed frame 1 through an assembly plate 12. A slit 131 for inserting the blades 25 is opened on the water-absorbing sponge 13. A cleaning liquid for specifically cleaning the blades 25 is absorbed in the water-absorbing sponge 13. A screw 11 is welded on the lower surface of the fixed frame 1. A through hole 121 for inserting the screw 11 is opened on the assembly plate 12. The screw 11 and the assembly plate 12 are fixed by a nut.

[0029] Among them, a mud guard 22 is clamped at the position of the upper end of the cutter shaft 23 of the lifting frame 2. The left and right ends of the mud guard 22 are slidably connected to the lifting frame 2. A pulling groove 221 is opened on the mud guard 22.

[0030] It should be noted that the mud guard 22 is provided to prevent soil and weeds from splashing onto the water-absorbing sponge 13 during rotary tilling, ensuring the cleanliness of the water-absorbing sponge 13. If the water-absorbing sponge 13 is frequently contaminated by mud, it is necessary to frequently replace or clean the water-absorbing sponge 13, which will increase the maintenance cost and workload.

[0031] Specifically, when it is necessary to clean the blade 25, the mudguard 22 is pulled outwards through the slot 221 until the mudguard 22 is withdrawn from the lifting frame 2. Then, the hydraulic cylinder 21 is started, and the hydraulic cylinder 21 drives the lifting frame 2 to move upwards. The lifting frame 2 drives the blade 25 to move upwards until the blade 25 is inserted into the slit 131. At this time, the water-absorbing sponge 13 will closely adhere to the surface of the blade 25. Then, the motor 26 is started to drive the blade 25 to rotate. While the blade 25 rotates, the water-absorbing sponge 13 will wipe off the soil and weeds adhered to the blade surface, achieving the cleaning effect;

[0032] The advantage of the water-absorbing sponge 13 absorbing the cleaning liquid is that it can dissolve and soften the caked soil and weeds on the surface of the blade 25;

[0033] When the water-absorbing sponge 13 becomes dirty after long-term use, the nut on the screw 11 can be removed, and the assembly plate 12 can be detached from the bottom of the fixed frame 1. Then, the water-absorbing sponge 13 is cleaned, and after being cleaned, it is reinstalled to achieve repeated use.

[0034] Working principle: For this rotary tillage mechanism that facilitates blade cleaning, when it is necessary to clean the blade 25, the mudguard 22 is pulled outwards through the slot 221 until the mudguard 22 is withdrawn from the lifting frame 2. Then, the hydraulic cylinder 21 is started, and the hydraulic cylinder 21 drives the lifting frame 2 to move upwards. The lifting frame 2 drives the blade 25 to move upwards until the blade 25 is inserted into the slit 131. At this time, the water-absorbing sponge 13 will closely adhere to the surface of the blade 25. Then, the motor 26 is started to drive the blade 25 to rotate. While the blade 25 rotates, the water-absorbing sponge 13 will wipe off the soil and weeds adhered to the blade surface, achieving the cleaning effect.
