Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to an integrated machine for laying film and pipes. Background Art

[0002] Drip irrigation is a relatively mature technology in water-saving irrigation. Drip tape is an important component for the successful implementation of drip irrigation. However, drip irrigation needs to be laid under the ground film at the same time as the spring crop planting to provide water for the subsequent growth and development of crops. Therefore, special equipment is needed to lay the ground film and drip tape at the same time.

[0003] Through searching, a trenching, soil covering, pipe laying and film covering all-in-one machine with announcement number CN207075188U is found, which includes: a trenching device, a scraper, a dropper reel, a frame and a film laying device arranged under the frame; the trenching device is located at the front end of the frame and is provided with a fixing extending to the position of the frame; the dropper reel is arranged in front of the film laying device, the film laying device is arranged on the frame, and the scraper is arranged between the trenching device and the film laying device; the front end of the frame is connected to the trenching device by a buckle; a length-adjustable balancing device is provided between the fixing and the frame.

[0004] However, the above-mentioned machine for trenching, covering soil, laying pipes and covering film with announcement number CN207075188U has the following two problems when laying drip irrigation tape: first, after a ridge of drip irrigation tape is laid and the drip irrigation tape is cut, the tractor will lift the drip irrigation tape laying machine and turn around to lay the next ridge. During the process of the tractor lifting the laying machine and turning around, the drip irrigation tape roller will shake and rotate, causing the cut end of the drip irrigation tape to flutter randomly; second, when laying the drip irrigation tape for each ridge, the end of the drip irrigation tape needs to be fixed to the end of each ridge, which is time-consuming and labor-intensive. Utility Model Content

In the process of the tractor lifting the laying machine and turning around, the drip tape roller will shake and rotate, causing the cut end of the drip tape to flutter randomly and the end of each ridge needs to be fixed when laying the drip tape for each ridge, which is time-consuming and labor-intensive.

[0036] The pressing wheel 9 is located directly behind the tube pressing assembly.

[0037] The pressing wheel 9 is located directly behind the pressing tube assembly and can be used to press the drip irrigation belt passing through the pressing tube assembly tightly onto the ground.

[0038] The blade of the pipe cutting shovel 37 is serrated.

[0039] The blade of the pipe cutting shovel 37 is serrated to make it easier to cut the drip irrigation tape.

[0040] When in use, the machine is connected to the rear of the tractor, and then the hydraulic oil pipe of the oil cylinder 33 is connected to the oil pump output interface of the tractor. The tractor pulls the machine to the ridge head of the field where the mulch film and drip irrigation tape need to be laid, and one side of the end of the drip irrigation tape passes through the guide tube 16, the gap between the jacket 17 and the pipe clamp 22, and the sliding curved groove 18. The end of the drip irrigation tape is pulled out from the lower end of the sliding curved groove 18 and passes directly under the pressure wheel 9, and then passes through the soil release roller 12 until the end of the drip irrigation tape is pulled over the bottom of the cutting assembly. At this time, the cutting assembly is in a raised state, and then the end of the mulch film is pulled down from the mulch film winding roller 4 so that it passes through the film spreading roller 45, the film pressing roller 48, and under the pressure wheel 9 in turn, passes under the soil release roller 12 and the cutting assembly After the parts are assembled, the end of the ground film is buried in the ridge head, and then the tractor is started to drive the machine forward. During the forward movement of the tractor, because the soil-releasing roller 12 is in contact with the ground, the steel wire pull line 27 connected to the shaft head 1201 of the soil-releasing roller 12 is in a relaxed state, so that the steel wire pull line 27 will not pull the connecting column 23 connected to the other end through the wire pull tube 25, thereby not pulling the pipe clamp 22 and the roller 19 connected to the pipe clamp 22 to press the drip irrigation belt passing through the middle toward the jacket 17. At the same time, when the machine is moving forward, the pressure wheel 9 will press the drip irrigation belt under the ground film downward along the end of the fixed arm 8 under the downward pressure of the torsion spring 10, thereby avoiding the problem of pulling the drip irrigation belt to follow the advancement of the machine.When the laying of a ridge of drip irrigation pipe and ground film is completed, it is necessary to lower the cutting assembly in the raised state to cut the ground film and drip irrigation tape. The specific operation is to control the hydraulic pump control switch of the tractor to supply oil to the oil cylinder 33, so that the lower end of the oil cylinder 33 extends, thereby driving one end of the movable arm 34 hinged to the lower end of the oil cylinder 33 to rotate and move downward along the fixed arm 35. The downward movement of the movable arm 34 thereby drives the cross bar 36 connected to its other end and the fixed plate 38 connected to both ends of the cross bar 36 to move downward accordingly. The downward movement of the fixed plate 38 will drive the pressure rod 39 hinged to its end to move downward, and then the lower end of the pressure rod 39 will drive the rotating shaft 41 of the film cutting blade 40 to move downward along the fixing part 42, which will press the ground film on the ground and cut it. When the cross bar 36 moves downward, it will drive the pipe cutting shovel 37 hinged to its lower surface to move downward in the through hole of the limiting wheel until the pipe cutting shovel contacts the drip irrigation tape under the ground film directly below and The drip irrigation tape is pressed, and the serrated blade at the end of the pipe cutting shovel will press and cut the drip irrigation tape on the ground. Then the tractor controls the tractor to raise the oil cylinder 33 and lift the cutting assembly. Then the tractor raises the entire machine to turn around and lay the next ridge of mulch and drip irrigation tape. In the process of the tractor raising the entire machine, the soil roller 12 will move downward with the connecting arm 11, and at the same time pull the steel wire pull line 27 connected to the shaft head 1201. The steel wire pull line 27 will slide in the pull line tube 25, pulling the connecting column 123 connected to the other end, and then pulling the pipe clamp 22 connected to the connecting column 123 and the roller 19 connected to the pipe clamp 22 to rotate along the fixed column 21 toward the jacket 17, which will tighten the drip irrigation tape passing between the two, solving the problem that the drip irrigation tape roller rotates during the machine lifting and turning around, pulling the end of the drip irrigation tape out of the pipe clamp assembly and causing it to float, and the drip irrigation tape needs to be manually inserted again during subsequent laying.
