As a further scheme of the invention, the air supply mechanism comprises a communication port 22 arranged on the rotary drum 04, the communication port 22 is communicated with the crushing cutter 13 through a ferrule 23, the positions of the two rotary shafts 15 in the air pump seat 09 are fixedly connected with an air pump valve 18 respectively, the air pump valve 18 consists of three valve heads 19 arranged in a circle center array, the adjacent positions of the air pump valves 18 are provided with embedded ports 20, the circle center diameter of the embedded ports 20 is consistent with the circle center diameter of the valve heads 19, the position of the valve heads 19 farthest from the rotary shafts 15 is in clearance fit with the position of the arc-shaped outline of the inner wall of the air pump seat 09 and the position of the embedded ports 20 on the air pump valve 18, the lower end of the air pump seat 09 is communicated with a communication pipe 08, the lower end of the communication pipe 08 is communicated with the rotary drum 04 and rotationally connected, and an air inlet for air intake is arranged above the air pump seat 09.
When the rotating shaft 15 rotates, the two air pump valves 18 are driven to rotate in opposite directions, and when the air pump valves 18 rotate, air is pushed downwards along the arc-shaped outline of the air pump seat 09 from above due to clearance fit of the inner walls of the air pump valves 18 and the air pump seat 09 until the lowest movement occurs, at the moment, the valve head 19 of the other air pump valve 18 can be extruded into the embedded port 20, so that the air is forced to enter the communicating pipe 08, and the air can be continuously sucked from the air inlet and then pushed into the communicating pipe 08, so that the air supply function is realized;
because the two rotating shafts 15 need to rotate in opposite directions so as to facilitate the crushing claw 06 to crush the soil and the crushing knife 13 to turn the soil, at the moment, the two air pump valves 18 need to rotate in opposite directions at the same time so as to realize the function of conveying air into the communicating pipe 08, the air pump valves 18 are arranged on the rotating shafts 15, so that the whole structure is more compact, the structure is simpler, the manufacturing cost is reduced, and the use cost is reduced by driving by using one driving source; in addition, because the air in the soil is airtight, the air does not circulate, and a common air blowing device is required to be used in an air circulation environment, but the air cannot be used in the soil, the extrusion type air conveying is realized through the rotation of the air pump valve 18, and the forced air supply can be realized, so that the air is forced to be blown into the soil, the air supply effect is ensured, and the soil loosening effect is improved.
As a further scheme of the invention, a positioning air outlet mechanism is further arranged in the rotary drum 04, the positioning air outlet mechanism comprises a shielding pipe 21 rotatably connected in the rotary drum 04, an opening 16 is formed below the shielding pipe 21 when the device works relative to the ground, a fixing rod II 17 is fixedly connected to the fixing rod I07, and the fixing rod II 17 is fixedly connected with the shielding pipe 21 after penetrating through the rotary drum 04 and is rotatably connected with the rotary drum 04.
In order to reduce the power of the driving source of the air pump valve 18 and the size of the communicating pipe 08, thereby reducing the use cost, air blowing is not required when the crushing cutter 13 rotates above the soil, thereby reducing the amount of air required to be conveyed by the communicating pipe 08, and thus reducing the power of the driving source and the size of the communicating pipe 08;
the shielding pipe 21 is arranged, the shielding pipe 21 is fixed on the first fixing rod 07 through the second fixing rod 17, so that the shielding pipe 21 cannot rotate along with the rotary drum 04, the shielding pipe 21 can block the communication opening 22 in the upper half part in the rotary drum 04, air cannot enter the communication opening 22 in the upper half part, air can be blown into the communication opening 22 only through the communication opening 22 in the lower half part, the crushing cutter 13 in the soil layer can blow out air, the crushing cutter 13 above the soil layer cannot blow out air, meanwhile, dust splashing is reduced, the comfort level of the use environment is improved, the size of the opening 16 can be adjusted according to the use requirement, and the area of blowing air in the soil can be adjusted between one hundred eighty degrees and thirty degrees;
because the crushing cutter 13 rotates rapidly, the soil splashes, and the possibly splashed soil can enter the air hole 24, or the soil can enter the air hole 24 when the crushing cutter 13 stops rotating, so that the use of the air hole 24 needs to be ensured;
when air enters the inner cavity 30, the air tap 26 is pushed to move towards the outside of the inner cavity 30 under the action of air pressure, so that the first air inlet hole 28 on the air tap 26 is overlapped with the second air inlet hole 29, air in the inner cavity 30 can enter the first air inlet hole 28 through the second air inlet hole 29 and then blow out through the air tap 26, air blowing is realized, when the communication port 22 is shielded by the shielding pipe 21, the air tap 26 is reset by the spring, the soil shielding column 25 can be propped against the first air inlet hole 28 on the air tap 26, sealing of the first air inlet hole 28 is ensured, and as soil possibly enters the position below the soil shielding column 25 in the air tap 26, a function is provided for intermittently blowing the soil in the air tap 26.
