[0002] At present, guiding and advocating farmers to use more organic fertilizers and less chemical fertilizers to achieve a virtuous cycle, improve the land farming environment, and use organic fertilizers scientifically is the key to improving fertility and efficiency. The traditional way of spreading organic fertilizers is to spread them on the surface of the soil of cultivated land, which is affected by wind, sun, and water, resulting in serious loss of nutrients in some fertilizers. Improving the fertilizer efficiency of organic fertilizers through scientific means, among which changing the traditional spreading method from surface fertilizer to deep underground fertilizer application is an important part of improving fertilizer efficiency.
[0003] The deep tiller can deeply till the soil. After deep tillage, the soil will present deep grooves with a depth greater than 30cm. The fertilization mechanism on the deep tiller will spread organic fertilizer into the grooves, and then achieve the purpose of deep fertilization of the land after backfilling and leveling the soil.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0023] Please see Figure 1 A deep tillage cutter head suitable for a deep tiller comprises a long crank 10, a blade tip 20, a pair of splints 30 and a joint tube 40. The long crank 10 is vertically arranged, the blade tip 20 is arranged at the lower end of the long crank 10, the pair of splints 30 are fixedly arranged on the long crank 10, a lower fertilizer cavity 310 is formed between the pair of splints 30 and the long crank 10, and the joint tube 40 is rotatably arranged on the pair of splints 30, one end of the joint tube 40 is sleeved in the lower fertilizer cavity 310, and the other end is located above the splint 30.
[0024] During the working process, first, the organic fertilizer will be crushed into powder, and then the powdered organic fertilizer will be loaded into the fertilizer box of the deep tiller. The powdered organic fertilizer will not block the fertilizer feeding channel. At the same time, the powdered organic fertilizer is easier to decompose and is beneficial to soil absorption. The selected long crank 10 is a crank greater than 30 cm. The longer crank can penetrate deeper into the soil. The blade tip 20 is used to break the soil. A pair of the splints 30 are located behind the long crank 10. A pair of the splints 30 are welded on the curved surface on the outside of the long crank 10, which is closed. The opposite side of the long crank 10 is open. The width between the pair of splints 30 is less than or equal to the width of the long crank 10 to avoid the splints 30 from being damaged. The width is wider. When the long crank 10 loosens the soil, the splint 30 generates greater resistance. The powdered organic fertilizer dropped from the deep loosening machine will fall into the joint pipe 40 and then fall into the lower fertilizer cavity 310. The soil broken by the knife tip 20 flows to the rear from both sides of the long crank 10, but the pair of splints 30 can block the backfilling of the loosened soil. The fertilizer in the lower fertilizer cavity 310 will fall into the deepest part of the soil broken by the knife tip 20. As the splint 30 moves forward, the backfilling of the loosened soil will bury the organic fertilizer and bury the organic fertilizer deep in the soil. At the same time, the pair of splints 30 are open, which can effectively prevent the powdered organic fertilizer from accumulating in the lower fertilizer cavity 310.
[0025] Effect achieved: by arranging a pair of the clamping plates 30 on the long crank 10, it is possible to avoid backfilling of loosened soil, delay the backfilling time of soil, and spread organic fertilizer at the deepest position of cultivated land. The buried depth of organic fertilizer is deep, and the organic fertilizer can provide nutrients to the deep soil, thereby achieving the effect of improving the fertilizer efficiency of the deep soil.
[0026] In a possible embodiment, a fertilizer flow port 320 is provided on the clamping plate 30, and the fertilizer flow port 320 is located at the lower end of the clamping plate 30. The powdered organic fertilizer in the lower fertilizer cavity 310 will flow out from the fertilizer flow port 320 and spread to both sides of the groove, thereby increasing the spreading area of the organic fertilizer and facilitating the soil to absorb nutrients in the organic fertilizer.
[0027] In a possible embodiment, the joint pipe 40 is provided with N sections, N ≥ 1, and the N sections of the joint pipe 40 are connected in sequence. Since the organic fertilizer is in powder form, the organic fertilizer is transported from the fertilizer box to the joint pipe 40 through a hose. If the hose is rigidly connected to the joint pipe 40, when the deep tiller shakes during movement, the hose will extend or shorten accordingly. When the extension is too large, the connection between the hose and the joint pipe 40 will break. By adopting the method of connecting the N sections of the joint pipe 40 in sequence, each section of the joint pipe 40 can rotate. When the hose is extended, it will drive the joint pipe 40 to rotate. First, it can avoid the connection between the hose and the joint pipe 40 from breaking; second, the joint pipe 40 and the hose are in an active state, which is more conducive to the powdered organic fertilizer flowing into the lower fertilizer cavity 310.
[0028] In a possible embodiment, a pair of transverse plates 110 are provided on the long crank 10, and the pair of transverse plates 110 are provided on both sides of the long crank 10. The transverse plates 110 are mainly used to horizontally scrape off tree roots and vines deep in the soil during the forward movement of the blade tip 20. The front end of the transverse plates 110 is not sharpened to prevent the transverse plates 110 from scratching the staff.
[0029] In a preferred embodiment, a guide plate 120 is provided on the long crank 10. The guide plate 120 is provided on the inner curved surface of the long crank 10, and the loosened soil is mainly guided to the rear from the inner curved surface of the long crank 10. By providing the guide plate 120, it is more conducive to diverting the soil to both sides of the long crank 10, thereby reducing soil resistance.
[0030] In a possible embodiment, the deep tillage cutter head suitable for a deep tillage machine further includes an extended handle 50, the extended handle 50 is fixedly connected to the long crank 10, and the extended handle 50 is located on a side away from the cutter tip 20. When the deep tillage machine tills the soil to a deeper depth, the overall length of the cutter handle can be increased by adding the extended handle 50.
[0031] In a preferred embodiment, a connecting plate 510 is provided on the extension handle 50, and a pair of bolts is provided on the connecting plate 510. The deep tillage cutter head is connected to the frame of the deep tiller through the connecting plate 510 and the pair of bolts.
[0032] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
