[0022] The top ends of the two first main pipes 76 are connected to the first water pipes 79 via two sets of first electric control valves 78, and are connected to the storage tank 4. The two first water pipes 79 and the two sets of first electric control valves 78 are connected by a first flexible hose 10. Under the action of pressure difference, the water-soluble fertilizer in the storage tank 4 is forced to be supplied by the two first water pipes 79 and reach the two first main pipes 76 through the first flexible hose 10 on the two sets of first electric control valves 78, which swings and extends with the movement, to provide water-soluble fertilizer supply. The outer ends of the two sets of first electric control valves 78 are embedded with first flow sensors to measure the water-soluble fertilizer that reaches the two sets of first electric control valves 78, thereby saving water-soluble fertilizer. The two sets of walking wheels 2 that follow the traction equipment are used as driving force to carry out large-scale spraying and fertilization operations on cotton, reducing the cost of driving equipment, improving the efficiency of cotton fertilization, and also fertilizing cotton evenly, which is conducive to maintaining the same growth of cotton and improving its yield.

[0023] like Figures 9-11 As shown, the two sets of side cylinder frames 6 are equipped with interlocking components, including a main bevel gear 81 fixed to the inner side of the two sets of worm gears 72 by a concentric shaft, and a bevel gear frame 82 meshing with the outer side of the main bevel gear 81. It also includes a driven bevel gear 83 meshing with the outer side of the two bevel gear frames 82. A reciprocating screw 84 that rotates with the two sets of side cylinder frames 6 is sleeved on the two sets of driven bevel gears 83, and a screw sleeve 85 is threadedly connected to the two sets of reciprocating screws 84. A bent arm 86 is fixed to the outer side of the two sets of screw sleeves 85. The two sets of worm gears 72 drive the main bevel gear 81 to rotate synchronously through the concentric shaft. The main bevel gear 81 drives the driven bevel gear 83 on the two sets of bevel gear frames 82 to rotate accordingly. The two sets of driven bevel gears 83 drive the screw sleeves 85 on the two reciprocating screws 84 to reciprocate up and down. And the outer side of the two groups of side tube racks 6 is provided with vertical grooves 18 sliding with the two bent arms 86, which play a sliding limiting role for the two bent arms 86, and the bottom of the two bent arms 86 is transversely provided with second manifolds 87, and the bottom ends of the two second manifolds 87 are arrayed and communicated with second spray heads 88, and when the two groups of screw sleeve 85 drive the second manifolds 87 on the two bent arms 86 to reciprocatingly ascend and descend, the two second manifolds 87 reciprocatingly ascend and descend in turn drive the two rows of second spray heads 88 to be inserted into the soil at the root of the cotton longitudinally back and forth, so as to drive the two rows of second spray heads 88 to perform the insertion type spraying and fertilizing operation on the soil around the cotton roots and stems in a reciprocating ascending and descending manner. And the second electric control valves 89 are arranged at the top ends of the two second manifolds 87, and the second flow sensors are embedded at the outer ends of the two groups of second electric control valves 89 to measure the water-soluble fertilizer reaching the two groups of second electric control valves 89, thereby saving the water-soluble fertilizer, and the inner ends of the two groups of second electric control valves 89 are communicated with the second water pipes 16 and the liquid storage tank 4, and the second hoses 17 are communicated between the two second manifolds 87 and the two groups of second electric control valves 89, so that under the action of differential pressure, the water-soluble fertilizer in the liquid storage tank 4 is supplied out from the two second water pipes 16 and reaches the two second manifolds 87 through the second hoses 17 which are followed by the second electric control valves 89 ascending and descending, thereby providing the water-soluble fertilizer for the two second manifolds 87, and still using the two groups of traveling wheels 2 which are moved by the traction equipment as driving force to perform the insertion type spraying and fertilizing operation on the soil around the cotton roots and stems, thereby improving the absorption efficiency of the fertilizer by the cotton roots under the premise of not wasting the fertilizer, and further promoting the beneficial growth of the cotton.

[0024] And the liquid storage tank 4 is provided with an auxiliary assembly, which comprises a differential gear 91 engaged with the main bevel gear 81, and further comprises a turbulence impeller 92 fixed on the differential gear 91 through a fan shaft to rotate turbulence at the bottom area of the liquid storage tank 4, and the fan shaft of the turbulence impeller 92 is longitudinally provided with a spiral knife holder 93, so that the turbulence impeller 92 and the spiral knife holder 93 on the differential gear 91 can simultaneously realize the effects of turbulence and anti-deposition and large-particle crushing on the water-soluble fertilizer in the liquid storage tank 4, thereby improving the fertilization sufficiency of the water-soluble fertilizer, preventing effective substances from being deposited and remaining, avoiding large-particle substances from blocking the pipeline, and playing a role in preventing blockage, and after the effective substances in the water-soluble fertilizer are analyzed and applied, it is also convenient for subsequent cleaning of the liquid storage tank 4 and reduces the cleaning burden.

[0025] As Figures 12-15As shown, during the period of the auxiliary assembly differential gear 91 driving the spoiler impeller 92 and the spiral tool holder 93 to disturb and break the water-soluble fertilizer effective substance in the liquid storage tank 4, the water-soluble fertilizer is easily affected by the external low temperature environment, which makes the effective substance in the water-soluble fertilizer difficult to dissolve, and the ice-cold water-soluble fertilizer also easily damages the cotton seedlings when fertilizing, even causes the phenomenon of frozen roots, reduces the survival rate of cotton seedlings, and is not worth the loss. The auxiliary assembly further includes a heat preservation cover 94 sleeved outside the liquid storage tank 4, and an electric heater 95 is embedded on both sides of the heat preservation cover 94, and a heating pipe 96 is arranged in the inner side of the two groups of electric heaters 95 in an array. The two groups of electric heaters 95 and the heating pipe 96 provide heat source to heat the water-soluble fertilizer in the liquid storage tank 4, so that it is quickly dissolved, and the utilization of the effective substance in the water-soluble fertilizer is further improved. And a conduction cavity 97 for heat conduction of the heating pipe 96 is reserved between the liquid storage tank 4 and the heat preservation cover 94, and a temperature sensor 98 is embedded on the outside of the heat preservation cover 94, which also heats and preserves the water-soluble fertilizer, so as to prevent the ice-cold water-soluble fertilizer from damaging the cotton seedlings in low temperature weather, avoid the phenomenon of frozen roots, and improve the survival rate of cotton seedlings.

[0026] The working principle of the cotton cultivation and fertilization device is as follows: first, the pulling frame 3 is connected with the traction equipment through a pin shaft, and the traction equipment drives the two groups of walking wheels 2 on the vehicle frame 1 to rotate and move along the cotton cultivation row through the connected pulling frame 3. During this period, the two groups of walking wheels 2 rotate and move, and the two groups of worm wheels 72 on the two worms 71 rotate, the two groups of swing arms 73 on the two groups of swing frames 74 horizontally displace, and the two groups of slide seats 12 slide in the transverse groove 11. At the same time, the two groups of slide seats 12 on the upper part drive the first main pipes 76 on the two groups of bent frames 75 to make reciprocating swing action, and then the two first main pipes 76 drive the two rows of first spray heads 77 to horizontally reciprocate and swing. Under the action of the differential pressure, the water-soluble fertilizer in the liquid storage tank 4 is forced to be supplied out through the two first water pipes 79, and reaches the two first main pipes 76 through the first flexible pipes 10 which follow the swing and stretch of the two groups of first electric control valves 78, and then is sprayed and fertilized to the cotton in a large range by the two rows of first spray heads 77 which horizontally reciprocate and swing. At the same time, the two groups of swing arms 73 also drive the combing teeth 14 and the tamping heads 15 on the two vertical rods 13 to horizontally reciprocate and swing, and comb the weeds in the cotton cultivation area, so that the water-soluble fertilizer sprayed and swung by the two rows of first spray heads 77 fully acts on the cotton plants, and the two groups of tamping heads 15 tamping the mud blocks adhered to the two groups of walking wheels 2, reducing the moving burden; At the same time, the two groups of worm gears 72 drive the main bevel gears 81 to rotate synchronously through the concentric shafts, and the main bevel gears 81 drive the slave bevel gears 83 on the two bevel gear racks 82 to rotate, and the two groups of slave bevel gears 83 drive the screw sleeves 85 on the two reciprocating lead screws 84 to reciprocate, and the two groups of screw sleeves 85 drive the second main pipes 87 on the two curved arms 86 to reciprocate, and then the two reciprocating second main pipes 87 drive the two rows of second spray heads 88 to penetrate into the soil at the root of the cotton. Similarly, under the action of the differential pressure, the water-soluble fertilizer in the liquid storage tank 4 is forced to be supplied out through the two second water pipes 16, and then reaches the two second main pipes 87 through the second flexible pipes 17 on the two groups of second electric control valves 89 that follow the lifting and stretching, and then is sprayed and fertilized by the two reciprocating second spray heads 88. During this period, the two groups of worm gears 72 drive the main bevel gears 81 to rotate through the concentric shafts, and the main bevel gears 81 synchronously drive the turbulence impeller 92 and the spiral cutter holder 93 on the differential gear 91 to rotate in the liquid storage tank 4, the turbulence impeller 92 rotates to prevent the effective substances in the water-soluble fertilizer from precipitating, and the effective substances are guided to the first water pipe 79 and the second water pipe 16, the spiral cutter holder 93 rotates to break and refine the large particles in the water-soluble fertilizer, and the liquid level sensor 19 monitors the liquid level of the water-soluble fertilizer in the liquid storage tank 4 in real time, and when the liquid level of the water-soluble fertilizer is low, the two groups of F-shaped buckles 20 are opened, and the tank cover is lifted to add the water-soluble fertilizer. According to the change of the external environment temperature, the two groups of electric heaters 95 are controlled to be turned on, and heat sources are generated through the heating pipes 96, then the two heat sources reach the conduction cavity 97 between the liquid storage tank 4 and the heat preservation cover 94, and the water-soluble fertilizer in the liquid storage tank 4 is heated under the action of heat conduction, so that it is quickly dissolved, and the liquid storage tank 4 is heat preserved for a long time by the heat preservation cover 94, when the external temperature is low, the water-soluble fertilizer after heating is used for protective fertilization of the cotton seedlings, and the temperature of the water-soluble fertilizer after heating is monitored by the temperature sensor 98, so that the temperature of the water-soluble fertilizer after heating is ensured to be in the best bearing interval of the cotton seedlings, until the water-soluble fertilizer fertilization of the cotton in the cultivation area is completed.
