[0035] like Figure 5 As shown, the other end of the connecting groove 4101 is provided with an outer protrusion 4102, and the upper end of the locking plate 415 is provided with a slot portion 4151. The locking plate 415 can be limited on the connecting groove 4101 by the snap connection between the slot portion 4151 and the outer protrusion 4102, and the other end of the connecting groove 4101 is a wedge-shaped surface 4103.

[0036] like Figure 5 As shown, a plurality of drip irrigation tape laying devices 3 are installed at the upper rear end of the frame 5 for laying the drip irrigation tape, and each drip irrigation tape laying device 3 is arranged in one-to-one correspondence with the former 4.

[0037] like Fig.10 , Fig.11As shown, the drip irrigation tape laying device 3 includes a drip irrigation tape 301, a drip irrigation tape mounting frame 302, a drip irrigation tape laying cylinder 303, a left drip irrigation tape covering plate 304 and a right drip irrigation tape covering plate 305; the drip irrigation tape 301 is wound on the drip irrigation tape mounting frame 302, and the drip irrigation tape mounting frame 302 is installed on the former body 410, the free end of the drip irrigation tape 301 is laid by the drip irrigation tape laying cylinder 303, and is covered with soil by the left drip irrigation tape covering plate 304 and the right drip irrigation tape covering plate 305 symmetrically arranged on both sides of the drip irrigation tape laying cylinder 303, the drip irrigation tape laying cylinder 303 passes through the forming cover plate 45 from the upper end to the bottom, the left drip irrigation tape covering plate 304 and the right drip irrigation tape covering plate 305 are installed on the bottom surface of the forming cover plate 45, and the left drip irrigation tape covering plate 304 and the right drip irrigation tape covering plate 305 are gradually closed.

[0038] The two drip irrigation belt guide tubes 306 are rotatably mounted on the lower end of the drip irrigation belt mounting frame 302. The two drip irrigation belt guide tubes 306 are arranged side by side with a gap. The drip irrigation belt 301 passes through the gap, which can play a certain guiding role.

[0039] Drip irrigation tape 301 specifications: plastic tube with a cross-section of about 20mm long and 2mm wide, supplied in rolls.

[0040] Working principle: The tractor transmits power to the gearbox 8 through the universal input shaft 9, and the gearbox 8 transmits power to the left and right rotary tillage and crushing units 6 in sequence. Under the action of the depth limiting wheel 1, the inter-cultivation depth is guaranteed to be consistent. A deep loosening shovel 2 is arranged in front of each rotary tillage and crushing unit 6 to loosen the soil first, greatly reducing the operating resistance of the rotary tillage blade 602 of the rotary tillage and crushing unit 6. After the rotary tillage and crushing unit 6 crushes the soil, the former 4 behind it will form a perfect ridge shape. At the same time as the ridge is formed, the drip irrigation tape 301 can be laid through the drip irrigation tape laying device 3. Equipped with a fertilization system 7, secondary fertilization can be carried out while inter-cultivation is carried out, thereby improving operating efficiency and increasing production.

[0041] Compared with the conventional three-link former, the four-link structure profiling former 4 has a compact structure and low tractor horsepower requirement. During the intertillage process, the drip irrigation belt 301 is laid to improve production efficiency. Moreover, after removing the forming cover plate 45 and the connecting square tube 46, it can be used for post-seedling intertillage (secondary intertillage).

[0042] When the machine is in operation, each ridge can be formed by the left plowshare 44, the right plowshare 42 and the forming cover plate 45. Figure 6 The former body 410, the upper adjustment link 411, the main body lower connecting frame 412, and the frame 5 form a four-link profiling mechanism, and the compression spring 13 applies upper pressure to achieve real-time profiling, thereby forming a full and defect-free ridge body. At the same time, the drip irrigation belt 301 can be laid, such as Fig.10As shown, the drip irrigation tape 301, under the action of the drip irrigation tape guide tube 306, can keep the patch on top in real time (the drip irrigation tape 301 is located between the two drip irrigation tape guide tubes 306), smoothly enter the drip irrigation tape laying tube 303, and smoothly lay the drip irrigation tape 301 to 3 centimeters below the ridge surface. Finally, under the joint action of the drip irrigation tape cover plate 304 on the left and the drip irrigation tape cover plate 305 on the right, the laying of the drip irrigation tape 301 is completed. Remove the forming cover plate 45 and the connecting square tube 46, and it can be used for post-seedling cultivation and forming. The connecting square tube 46 can keep each former body 410 on the same horizontal plane, so that the height of each ridge surface is consistent. When used for post-seedling operations, the connecting square tube 46 can be quickly removed. The specific quick-release structure is as follows: Fig. 9 As shown, the locking plate 415 moves downward along the former body 410 (wedge principle) under the action of the eye bolt 416, and presses and locks the connecting square tube 46 to achieve rapid installation.
