[0028] The raw materials and instruments used in the examples are not specifically limited in source, and can be purchased on the market or prepared according to conventional methods well known to those skilled in the art.

[0029] As Figures 1 to 4 shown, the drip irrigation tape laying device according to the preferred embodiment of the present application comprises a support frame 4, a winding and unwinding mechanism 1, a pipe laying mechanism 2 and a soil covering mechanism 3.

[0030] The support frame 4 comprises a main beam 41, a sub-beam 42 and a plurality of vertical beams 43 for connecting the main beam 41 and the sub-beam 42. The main beam 41, the sub-beam 42 and the vertical beams 43 are all profiled steel. The main beam 41 is on top, the sub-beam 42 is on the bottom, and the vertical beams 43 are horizontally arranged between the main beam 41 and the sub-beam 42. The upper and lower ends of the vertical beams 43 are respectively welded to the main beam 41 and the sub-beam 42.

[0031] The winding and unwinding mechanism 1 comprises a reel 11, a rotating shaft 13, a support shaft 14, a latch 15 and a support assembly 12. The support assembly 12 comprises a first vertical support pipe 121 and a second vertical support pipe 122. The bottom of the first vertical support pipe 121 and the bottom of the second vertical support pipe 122 are welded to the upper surface of the main beam 41. The rotating shaft 13 is coaxially arranged with the reel 11, and the reel 11 is relatively rotatable about the rotating shaft 13. One end of the rotating shaft 13 is welded to and perpendicular to the support shaft 14, and the support shaft 14 is arranged in and rotatably connected to the first vertical support pipe 121. The other end of the rotating shaft 13 is connected to the second vertical support pipe 122 through the latch 15, i.e. the latch 15 can penetrate the rotating shaft 13 and be inserted into the second vertical support pipe 122, and the detachable connection between the rotating shaft 13 and the second vertical support pipe 122 is achieved by plugging and unplugging the latch 15.

[0032] Reference Figure 3 When it is necessary to replace the drip irrigation tape, the latch 15 is pulled out, the reel 11 is rotated to a position convenient for the operator to work, and then the operator can directly wind the drip irrigation tape on the reel 11, so that the entire reel 11 does not need to be disassembled, and the operator does not need to lift the reel together with the drip irrigation tape back to the original position, which saves time and effort.

[0033] The pipe laying mechanism 2 comprises a base 21, a guide 23 and connecting rods 22. The base 21 is partly welded by square steel pipes and steel plates, and the other part is a lifting adjusting rod which is arranged in the square steel pipe. The function of the lifting adjusting rod will be described later. The square steel pipe is arranged vertically on the surface of the steel plate. The steel plate is used to be fixed on the secondary beam 42 by U-shaped bolts. The guide 23 comprises a connecting piece 233, a guide pipe 231, a plough 232 and an adjuster 24. The connecting piece 233 is welded with the guide pipe 231, and the connecting piece 233 is connected with the base 21 by the connecting rods 22 to form a four-bar linkage mechanism. The basic four-bar linkage mechanism only needs to use two connecting rods 22, but in order to realize the symmetrical balance of stress, four connecting rods 22 are symmetrically arranged on the left and right sides of the base 21. In addition, the two nodes of the diagonal line of the four-bar linkage mechanism are connected by springs to generate a downward force on the guide 23, so that the guide 23 can be stably attached to the soil surface and move. The guide pipe 231 is arranged in an "L" shape and serves to guide the drip irrigation belt. The plough 232 is welded to the bottom of the guide pipe 231, and the plough 232 is arranged towards the support frame 4, and the pipe opening at the bottom of the guide pipe 231 is arranged away from the support frame 4. In use, the plough 232 is inserted into the soil, and under the action of the traction equipment, the plough 232 completes the ditching in the soil, and then the drip pipe is sent into the ditch from the guide pipe 231 to realize the pipe laying. The pipe opening at the bottom of the guide pipe 231 is arranged as a flat opening to limit the longitudinal movement of the drip pipe. The adjuster 24 is located above the guide pipe 231, and the adjuster 24 comprises a frame 241, a fixed roller 242 and an adjusting roller 243. The fixed roller 242 and the adjusting roller 243 are both arranged on the inner side of the frame 241, and they are parallel and have a spacing for the drip irrigation belt to pass through. The two ends of the fixed roller 242 are fixedly connected with the frame 241. The positions of the frame 241 corresponding to the two ends of the adjusting roller 243 are provided with a waist-shaped hole. The two ends of the adjusting roller 243 penetrate the waist-shaped hole and are axially limited by a clasp spring, so that the adjusting roller 243 can move along the waist-shaped hole and rotate by itself. A spring is arranged between the two opposite ends of the fixed roller 242 and the adjusting roller 243 to connect them, so as to generate a pulling force on the adjusting roller 243 to move towards the fixed roller 242, so that the spacing between the fixed roller 242 and the adjusting roller 243 can be changed and can adapt to drip irrigation belts of different sizes. The adjuster 24 serves to constrain the position of the drip irrigation belt and make the drip irrigation belt enter the guide pipe 231 smoothly. The drip pipe sent out from the reel 11 will first pass through the adjuster 24 to avoid damage caused by the contact between the drip irrigation belt and other structures in the pipe laying mechanism 2, and then enter the guide pipe 231.

[0034] The soil covering mechanism 3 comprises a soil scraper 31 and a cable 32. The soil scraper 31 is a profile steel, and its length should not be shorter than the main beam 41. The two ends of the cable 32 are connected with the main beam 41 and the soil scraper 31 respectively, that is, the cable 32 is fastened by bolts after being tied. Two cables 32 are arranged to ensure that the soil scraper 31 moves smoothly during the movement. During the movement, the soil scraper 31 will scrape the soil on both sides of the ditch into the ditch to realize the land leveling operation.

[0035] In order to improve the work efficiency, a plurality of collecting and releasing mechanisms 1 and pipe laying mechanisms 2 are arranged on the support frame 4, and the covering mechanism 3 only needs one.

[0036] In addition, the following structures need to be explained. Firstly, the lifting adjusting rod 25 is provided with a plurality of through holes arranged at equal intervals. The lifting adjusting rod 25 in the base 21 is fixedly connected with the square steel pipe through bolts. The lifting adjusting rod 25 can change the node position of the four-bar linkage mechanism. The relative position of the lifting adjusting rod 25 and the square steel pipe can be adjusted, and the through holes on the lifting adjusting rod 25 can also be used for the node connection of the four-bar linkage structure, so that the position of the guide 23 can be changed.

[0037] Secondly, the two horizontal relative connecting rods 22 are connected through the first bolt 26 to limit the relative distance of the two, and the purpose is to limit the left and right shaking of the guide 23 in the use process. In the use process, due to the vibration of the machine and the external force in the ditching process, the limiting snap spring at the node of the connecting rod 22 and the guide 23 will be seriously worn, when the snap spring loses the original thickness, the limiting ability of the end of the connecting rod 22 is weakened, which makes the laying track of the drip irrigation belt unstable, and even the fatigue fracture of the connecting rod 22. After the interval of the two connecting rods 22 is forcedly constrained by the first bolt 26, the left and right shaking of the guide 23 can be limited, so that this problem can be solved.

[0038] The utility model discloses a preferred embodiment of a seeding and laying integrated machine, which comprises a tractor, a seeding machine and a drip irrigation belt laying device as described above. The seeding machine is installed at the tail of the tractor, and the support frame 4 of the drip irrigation belt laying device is fixedly connected with the seeding machine, for example, the main beam 41 can be connected with the metal frame in the seeding machine by welding. In use, the tractor pulls the seeding machine and the drip irrigation belt laying device, the seeding machine seeds on the ground, and the drip irrigation belt laying device lays the drip irrigation belt. The guide pipe 231 is arranged in a staggered manner with the seeding pipe in the seeding machine to ensure the laying of the drip irrigation belt and the seed row.

It is apparent that many modifications and variations are possible in light of the above teachings. It is intended to cover all such modifications and variations as long as they fall within the scope of the claims. The scope of the application is intended to be limited only by the claims.
