Description

Technical Field

[0001] The utility model relates to the technical field of trenching and pipe laying equipment, and more specifically, to a disc-type trenching and pipe laying machine for laying underground drip irrigation pipes in an orchard. Background Art

[0002] At present, the common method for laying drip irrigation pipes is: first, a trench is made on the ground by a trench opener, then the drip irrigation pipe is laid in the trench, then the trench is backfilled with soil, and finally the soil is compacted. However, this method is cumbersome and inefficient. Therefore, people invented trenching and pipe laying equipment. For example, the patent with application number 202222602964.6 discloses a trenching and pipe laying device, including a frame, which is installed and connected to a traction power device; the frame is connected to a wing plate, the wing plate is connected to an adjusting rod, and the bottom end of the adjusting rod is connected to a trenching shovel; it also includes a concealed pipe rack, the concealed pipe rack includes a support frame installed on the traction power device, the support frame is rotatably connected to a vertically arranged rotating drum, and a concealed pipe is sleeved and wound on the rotating drum; the side wall of the adjusting rod is also integrated with a guide seat for guiding and laying the concealed pipe, and an obliquely arranged vertically through cavity is provided inside the guide seat, and one end of the concealed pipe passes through the cavity; an upper guide wheel group and a lower guide wheel are rotatably provided in the cavity along the up and down directions respectively; it also includes a soil covering and suppression mechanism; in addition, a pipe smoothing device is also connected to the top of the support frame.

[0074] A bearing accommodating groove can be coaxially arranged at the first through hole opened on the inner sleeve bracket 301 described here, and a bearing can be arranged in the bearing accommodating groove, so that the flange shaft 304 and the inner sleeve bracket 301 can be rotatably connected through the bearing to reduce friction resistance. Similarly, a bearing can be arranged on the outer sleeve bracket 302 like the inner sleeve bracket 301 to reduce the rotational friction resistance between the flange shaft 304 and the outer sleeve bracket 302.

[0075] In the above embodiment, the inner sleeve bracket 301 and the outer sleeve bracket 302 provide support for the flange shaft 304 of the trenching cutter disc 303 to ensure that the flange shaft 304 can rotate smoothly, and the cutter disc guard 306 is used to cover the top of the trenching cutter disc 303 to prevent the flying of soil caused by the rolling trenching process of the trenching cutter disc 303 and accidentally injuring the staff working with the equipment.

[0076] More specifically, the trenching cutter disc 303 includes:

[0077] Base disc 3031;

[0078] The first grooving tooth 3032 and the second grooving tooth 3033 are alternately arranged along the edge of the base disk 3031, and the tooth roots of the first grooving tooth 3032 and the tooth roots of the second grooving tooth 3033 are respectively connected to the edges of the disk surface on both sides of the base disk 3031, and the tooth tips of the first grooving tooth 3032 and the tooth tips of the second grooving tooth 3033 are inclined toward each other's tooth roots on the disk surface to form an interlaced shape.

[0079] In the above embodiment, two forms of grooving teeth are alternately arranged on the two side surfaces of the base disc 3031. The two forms of grooving teeth have inclined tooth surfaces and staggered tooth tips, which can evenly discharge soil to both sides of the base disc 3031, ensure that both sides of the base disc 3031 are evenly stressed, and reduce resistance and wear on the grooving cutter disc 303 during the grooving process.

[0080] Specifically, Figures 5-6 As shown, the tube placement rack 5 includes:
