At this time, the pressure roller 704 will rotate and drive the limiting slide block 703 to move along the limiting slide rod 701, accordingly, the pressure plate 7 will also be extruded downward by the extrusion column 601, and the pressure plate 7 will press down the booster plate 1201 and the pressure spring 1202 through the connecting rod 12, at this time, the air pressure in the dust falling box 4 increases, and the water is sprayed from the mist nozzle 402 to the soil after plowing and the plowing device 202 under the action of air pressure, so that the working state of the cooling and dust falling assembly can be intermittently controlled.

[0052] The working principle of the soil improvement plowing device is: the device can be connected with the traction vehicle, the fertilizer hopper 5 can sprinkle the fertilizer before plowing, and the fertilizer can add a special fertilizer formula specially designed for tea trees, such as increasing the proportion of nitrogen, phosphorus and potassium, to meet the growth needs of tea trees. In addition to common organic matters such as compost and straw, tea tree pruning residues and other organic materials can also be considered, which not only can improve the soil structure, but also can provide more direct nutrient sources for tea trees, increase organic matter, improve water retention capacity and nutrient supply. Mixing these organic matters with soil not only makes them penetrate into soil better, but also provides nutrients for microorganisms in soil, promotes the growth and activity of microorganisms, and further improves the physical and chemical properties of soil. The plowing device 202 can plow the soil after fertilization, making the soil soft and uniformly distributing the fertilizer to the soil, which is beneficial to the growth of crops. The mixing and fertilizing assembly of the device can fully mix the fertilizer to ensure that the fertilizer is evenly distributed in the soil to provide sufficient nutrients for the growth of crops. At the same time, after the plowing process, the preliminary compaction of soil by the drag plate 1101 can promote the fixation of tea tree roots in soil and improve the water retention capacity of soil. Subsequently, the mulching roller 1001 can cover the mulch on the soil surface to play a protective role.

[0053] The plowing device 202 drives the transmission shaft 9 to rotate when it works, and the swing arm 901 rotates accordingly. Under the drive of the incomplete gear 902, the transmission gear 6 also rotates, and accordingly, the stirring rod 501 drives the mixing paddle 502 to mix the fertilizer in the fertilizer hopper 5, ensuring uniform distribution.

[0054] When the transmission shaft 9 rotates, under the action of the belt 801 and the small roller 8, the large roller 802 also drives the supporting rod 301 and the fixed wheel 10 to rotate, and correspondingly, the mulch roller 1001 also rotates, so that the mulch speed of the mulch roller 1001 can be controlled according to the rotating speed of the plowing device 202, the rotating speed of the mulch roller 1001 is synchronized with the rotating speed of the plowing device 202, and it is ensured that the mulch film will not be loose during mulching;

[0055] When the transmission gear 6 rotates, the plurality of extrusion columns 601 arranged thereon extrude the pressure roller 704 at the rotating time, at this time, the pressure roller 704 rotates and drives the limiting sliding block 703 to move along the limiting sliding rod 701, correspondingly, the pressure plate 7 is also extruded downward by the extrusion columns 601, the pressure plate 7 presses the booster plate 1201 and the pressure spring 1202 downward through the connecting rod 12, at this time, the air pressure in the dust falling box 4 increases, and the water is sprayed in the form of mist from the mist nozzle 402 to the soil after plowing and the plowing device 202, which can not only perform dust falling treatment on the soil after plowing, but also cool the plowing device 202; the process is performed before the mulching process, and the water is sprayed before the mulch film is covered, which not only can reduce the generation of dust, but also can keep the soil surface moist, reduce the suspension of soil particles, effectively reduce the dust flying in the tea garden, make the working environment more comfortable, and reduce the influence on human health; the water spraying intensity can be adaptively adjusted through the rotating speed of the plowing device 202, which can not only effectively control the dust, but also avoid excessive water spraying to make the soil too wet;

[0056] The device has the functions of mixed fertilization, plowing, mulching, dust falling and cooling, and can meet the requirements of various soil improvement operations, and through the dust falling and cooling design, the generation of dust and the influence on the environment are reduced, and the requirements of sustainable development are met.

A method of tilling soil using the soil-conditioning tiller of claim 5, wherein The method comprises the following steps: S1: connecting the device with the traction carrier, mixing the fertilizer in the fertilizer hopper (5) through the mixed fertilizer assembly, and ploughing the soil after fertilization through the ploughing device (202), wherein the transmission shaft (9) is driven to rotate when the ploughing device (202) works, the swing arm (901) is driven to rotate at this time, the transmission gear (6) is also driven to rotate under the drive of the incomplete gear (902), correspondingly, the stirring rod (501) also drives the mixing paddle (502) to mix the fertilizer in the fertilizer hopper (5), so that the fertilizer is uniformly distributed; S2: when the transmission shaft (9) rotates, the large roller (802) also drives the supporting rod (301) and the fixed wheel (10) to rotate under the action of the belt (801) and the small roller (8), correspondingly, the film rolling roller (1001) also rotates, so that the film rolling speed of the film rolling roller (1001) can be controlled according to the rotating speed of the ploughing device (202), and the loosening of the film during film rolling is avoided. S3: When the transmission gear (6) rotates, the plurality of extrusion columns (601) arranged thereon will extrude the rotating intermittent pressure roller (704), at this time the pressure roller (704) will rotate and drive the limiting sliding block (703) to move along the limiting sliding rod (701), accordingly, the pressure plate (7) will also be extruded downward by the extrusion column (601) as a whole, the pressure plate (7) will press down the pressure spring (1202) and the pressure plate (1201) through the connecting rod (12), at this time the air pressure in the dust falling box (4) increases, and the clean water is sprayed from the mist nozzle (402) to the soil after plowing and the plowing device (202) under the action of air pressure, on the one hand, the soil after plowing can be treated by dust falling, and on the other hand, the plowing device (202) can be cooled.
