[0011] As a further solution of the present invention, the convenient connection mechanism includes a stepped shaft. One end of the stepped shaft passes through the outer surface of the protective box and is rotatably installed thereon. One end of the stepped shaft is in an open structure. A movable shaft is slidably installed inside the stepped shaft. A spring is provided between the movable shaft and the stepped shaft.

[0013] A method for using a no-till seeding drip irrigation belt anti-slip laying device comprises the following steps:

[0014] Step 1: First, the main bracket is fixedly connected to the tractor, and then the first cover is opened to pour the seeds into the seed box, and then the second cover is opened to place the drip irrigation tape roll body. Before placement, the main shaft is taken out, and then multiple drip irrigation tape roll bodies are fixedly nested on the main shaft surface in turn. Both sides of each drip irrigation tape roll body are positioned by retaining rings, and then the main shaft carrying the drip irrigation tape roll body is horizontally placed in the shaft groove opened in the drip irrigation tape storage box, and the two ends of the main shaft are respectively connected to two convenient connection mechanisms;

[0015] Step 2: When taking and placing the spindle, you only need to push the movable shaft into the stepped shaft to squeeze the spring. After the spindle is in place, release the movable shaft and insert its end into the limiting hole of the spindle, so that the spindle and the stepped shaft rotate synchronously.

[0016] Step 3: Then, pass the end of the drip irrigation belt around the surface of the drum, pass it through the drip irrigation belt storage box and the main bracket, pass it through the drip irrigation belt positioning tube, and then lay it flat on the ground, and then fix the end of the drip irrigation belt at the end of the field;

[0017] Step 4: As the tractor pulls the equipment to move, the rotation of the wheel drives the active sprocket to rotate, and then drives the stepped shaft to rotate, the stepped shaft drives the main shaft to rotate, and the main shaft drives multiple drip irrigation tape roll bodies to rotate to release the drip irrigation tape. At the same time, the second weeding knife removes the weeds and hard soil blocks on the laying route of the drip irrigation tape, and pushes out a drip groove through the slotting block, so that the drip holes on the surface of the drip irrigation tape are facing the drip groove after laying, to prevent the drip holes from being blocked by broken soil and weeds. As the stepped shaft rotates, it drives the active pulley to rotate, and then drives the reciprocating screw to rotate. The reciprocating screw drives the drip irrigation tape storage box to slide back and forth. The reciprocating movement keeps the drip irrigation tape released from directly above the square hole to prevent the drip irrigation tape from twisting. Combined with the drip irrigation tape positioning tube, the drip irrigation tape can be effectively prevented from deviating from the laying route.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By setting up a drip groove opening mechanism, before the drip irrigation tape is laid on the ground, weeds and relatively hard soil clods can be removed on its laying route, and a drip groove for protecting the water outlet holes of the drip irrigation tape can be opened by a grooving block. Then, the drip groove is reinforced by a soil pressing edge, effectively preventing the water dripping holes of the drip irrigation tape from being blocked by broken soil and weeds. The depth of the drip groove opening can also be controlled by adjusting bolts, enabling it to be applicable to various terrains and improving the smoothness of water outflow after the drip irrigation tape is laid.

[0020] 2. By setting up a convenient connection mechanism, the disassembly of the main shaft is made more convenient, and the main shaft can drive the rotation of the drip irrigation tape roll body during the laying process, avoiding large pulling forces during the release of the drip irrigation tape and preventing deformation, which reduces the service life of the drip irrigation tape. At the same time, the convenient disassembly and assembly of the main shaft make the replacement of the drip irrigation tape roll body more convenient, improving the convenience of equipment use and thus enhancing the efficiency of the equipment for laying the drip irrigation tape.

[0021] 3. By setting up a reciprocating lead screw to drive the drip irrigation tape storage box to move back and forth in the protection box, and combining with the winding path of the drip irrigation tape roll body, the drip irrigation tape roll body is always directly above the square hole during the process of releasing the drip irrigation tape, avoiding intermittent offset release of the drip irrigation tape and friction loss with the square hole, which affects the service life of the drip irrigation tape. At the same time, combined with the drip irrigation tape positioning tube, the drip irrigation tape can be effectively prevented from twisting or deviating from the planned route after being laid, improving the stability of the drip irrigation tape after laying.

A first cover plate 5 and a second cover plate 6 are hinged to the top of the protective box 3. Both the first weeding knife 7 and the second weeding knife 802 are in a J-shaped structure. A scale line 701 is opened on the surface of the first weeding knife 7. A plurality of limiting grooves 1901 are opened on the surface of the main shaft 19. A retaining ring 24 for positioning the drip irrigation belt reel body 13 is embedded in each limiting groove 1901. Blind hole-shaped limiting holes 1902 are opened at both ends of the main shaft 19. By setting the drip groove opening mechanism 8, the present invention can remove weeds and relatively hard soil blocks on the laying route of the drip irrigation belt before the drip irrigation belt is laid on the ground, and open a drip groove for protecting the water outlet holes of the drip irrigation belt through the grooving block 803, and then reinforce the drip groove through the pressing edges 804, effectively avoiding the water dripping holes of the drip irrigation belt from being blocked by broken soil and weeds. The depth of the drip groove opening can also be controlled through the adjusting bolt 806, so that it can be applicable to various terrains, improving the smoothness of water outflow after the drip irrigation belt is laid.

The plurality of sowing tubes 9 respectively correspond to a plurality of first weeding knives 7.

[0036] During use, the drip irrigation tape positioning tube 11 also corresponds to the second weeding knife 802. By setting the reciprocating lead screw 25 to rotate to drive the drip irrigation tape storage box 12 to reciprocate in the protection box 3 and combining with the winding path of the drip irrigation tape roll body 13, the drip irrigation tape roll body 13 is always located directly above the square hole 1204 during the process of releasing the drip irrigation tape, avoiding the intermittent offset release of the drip irrigation tape and friction loss with the square hole 1204, thereby affecting the service life of the drip irrigation tape. At the same time, combining with the drip irrigation tape positioning tube 11 can effectively avoid the torsion or deviation from the planned route of the drip irrigation tape after laying, improving the stability of the drip irrigation tape after laying.

[0037] In this embodiment, the convenient connection mechanism 20 includes a stepped shaft 2001. One end of the stepped shaft 2001 passes through the outer surface of the protective box 3 and is rotatably installed thereon. One end of the stepped shaft 2001 is of an open structure. A movable shaft 2002 is slidably installed inside the stepped shaft 2001. A spring 2003 is provided between the movable shaft 2002 and the stepped shaft 2001.

The driven pulley 16 is fixedly sleeved on the surface of the reciprocating lead screw 25. A belt 17 is sleeved between the driving pulley 18 and the driven pulley 16.

[0038] During use, by setting the convenient connection mechanism 20, the disassembly of the main shaft 19 is made more convenient, and the drip irrigation tape roll body 13 can be driven to rotate during the laying process, avoiding deformation of the drip irrigation tape due to excessive pulling force during the release process, reducing the service life of the drip irrigation tape. At the same time, through the convenient disassembly and assembly of the main shaft 19, the replacement of the drip irrigation tape roll body 13 is made more convenient, improving the convenience of equipment use, and thus improving the efficiency of the equipment for laying the drip irrigation tape.

[0039] A method for using a no-till seeding drip irrigation tape anti-disconnection laying device includes the following steps:

[0040] S1: First, fixedly connect the main bracket 1 with a tractor. Then, open the first cover plate 5 to pour seeds into the seed box 15. Then, open the second cover plate 6 to place the drip irrigation tape roll body 13. Before placing, first take out the main shaft 19, and then sequentially and fixedly nest a plurality of drip irrigation tape roll bodies 13 on the surface of the main shaft 19. Both sides of each drip irrigation tape roll body 13 are positioned by retaining rings 24. Then, horizontally place the main shaft 19 carrying the drip irrigation tape roll body 13 in the shaft groove 1201 opened in the drip irrigation tape storage box 12, and connect both ends of the main shaft 19 with the two convenient connection mechanisms 20 respectively;

[0041] S2: When taking and placing the spindle 19, it is only necessary to push the movable shaft 2002 toward the inside of the stepped shaft 2001 to squeeze the spring 2003. After the spindle 19 is placed in place, the movable shaft 2002 is released and its end is inserted into the limiting hole 1902 provided on the spindle 19, so that the spindle 19 and the stepped shaft 2001 rotate synchronously;

[0042] S3: Then, the end of the drip irrigation belt is passed around the surface of the drum 1205, and then passes through the drip irrigation belt storage box 12 and the main bracket 1 and passes through the drip irrigation belt positioning tube 11, and then laid flat on the ground, and then the end of the drip irrigation belt is fixed at the edge of the field;

[0043] S4: As the tractor pulls the equipment to move, the wheel 2 rotates to drive the active chain plate 21 to rotate, and then drives the stepped shaft 2001 to rotate. The stepped shaft 2001 drives the main shaft 19 to rotate, and the main shaft 19 drives multiple drip irrigation tape roll bodies 13 to rotate and release the drip irrigation tape. At the same time, the second weeding knife 802 removes the weeds and hard soil blocks on the laying route of the drip irrigation tape, and pushes out a drip groove through the slotting block 803, so that the drip holes on the surface of the drip irrigation tape after laying are facing the drip groove, so as to avoid the drip holes being blocked by broken soil and weeds. As the stepped shaft 2001 rotates, it drives the active pulley 18 to rotate, and then drives the reciprocating screw rod 25 to rotate. The reciprocating screw rod 25 drives the drip irrigation tape storage box 12 to slide back and forth. The reciprocating movement keeps the drip irrigation tape released from directly above the square hole 1204 to avoid the drip irrigation tape from twisting. Combined with the drip irrigation tape positioning tube 11, the drip irrigation tape can be effectively prevented from deviating from the laying route.

[0044] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.

8. A method for using a no-tillage seeding drip irrigation tape anti-disconnection laying device, characterized in that, Adopting a no-till sowing drip irrigation tape anti - detachment laying device according to any one of claims 1 - 7, includes the following steps: S1: First, the main support (1) is fixedly connected to the tractor, then the first cover plate (5) is opened to pour seeds into the seed box (15), then the second cover plate (6) is opened to place the drip irrigation tape roll body (13), before placement, the main shaft (19) is first taken out, then a plurality of drip irrigation tape roll bodies (13) are fixedly nested on the surface of the main shaft (19) in sequence, and both sides of each drip irrigation tape roll body (13) are positioned by a retaining ring (24), then the main shaft (19) carrying the drip irrigation tape roll body (13) is horizontally placed in the shaft groove (1201) opened in the drip irrigation tape storage box (12), and the two ends of the main shaft (19) are respectively connected to two convenient connection mechanisms (20); S2: When taking or placing the spindle (19), it is only necessary to push the movable shaft (2002) toward the inside of the stepped shaft (2001) to squeeze the spring (2003). After the spindle (19) is placed in place, the movable shaft (2002) is released and its end is inserted into the limiting hole (1902) provided in the spindle (19), so that the spindle (19) and the stepped shaft (2001) rotate synchronously. S3: Then, the end of the drip irrigation tape is passed around the surface of the rotating drum (1205), passed through the drip irrigation tape storage box (12) and the main bracket (1) and passed through the drip irrigation tape positioning tube (11), and then laid flat on the ground, and then the end of the drip irrigation tape is fixed at the edge of the field; S4: As the tractor pulls the equipment to move, the wheel (2) rotates to drive the active chainring (21) to rotate, and then drives the stepped shaft (2001) to rotate, the stepped shaft (2001) drives the main shaft (19) to rotate, and the main shaft (19) drives the plurality of drip irrigation tape roll bodies (13) to rotate to release the drip irrigation tape, and at the same time the second weeding knife (802) removes the weeds and hard soil blocks on the drip irrigation tape laying route, and pushes out a drip groove through the slotting block (803), so that the drip irrigation tape is laid smoothly. The drip holes on the surface of the rear part are directly opposite to the drip groove, so as to prevent the drip holes from being blocked by broken soil and weeds. As the stepped shaft (2001) rotates, the driving pulley (18) is driven to rotate, thereby driving the reciprocating screw rod (25) to rotate. The reciprocating screw rod (25) drives the drip irrigation tape storage box (12) to slide back and forth. The reciprocating movement allows the drip irrigation tape to be released from directly above the square hole (1204), so as to prevent the drip irrigation tape from twisting. Combined with the drip irrigation tape positioning tube (11), the drip irrigation tape can be effectively prevented from deviating from the laying route.
