Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery and equipment, and relates to a drip irrigation belt laying device. Background Art

[0002] After the land is tilled and prepared, drip irrigation pipes / tapes are laid in arid areas to save water. There are drip irrigation pipes placed on the surface and thin-walled drip irrigation tapes buried underground. The buried depth of thin-walled drip irrigation tapes is generally 2-5 cm, which is used to prevent wind and bird pecking.

[0003] Existing drip irrigation tape laying machines, such as the drip irrigation tape laying machine proposed in publication number CN112237126A, focus on the design of the cutting mechanism in addition to the drip irrigation tape lead-out mechanism, without considering the function of covering the soil after laying. Another example is the adjustable shallow buried drip irrigation tape laying device with publication number CN204742082U, which uses two figure-eight scraper coverers to bury the drip irrigation tape in the soil, and adjusts the height of the covering wheel by a spring. There are soil-breaking wheels and furrowing plows in the front, and its structure is similar to the furrowing and covering of the seeder. The furrowing depth depends on the depth-limiting wheel. If a large clod is encountered, the depth-limiting wheel may pass through, which may cause the furrowing to be shallow, and the corresponding drip irrigation tape may not be buried deep enough. The figure-eight scraper may cause the drip irrigation tape to be cut out. Another example is the drip irrigation tape laying machine designed and manufactured by an Israeli company. It digs furrows and lays tapes, and also uses guide wheels to transmit the drip irrigation tape. The following uses Figure 1 The soil covering rake suspended by the iron chain shown is not suitable for removing the soil with large lumps or too fine soil layers, and the soil covering effect is not good.

DETAILED DESCRIPTION

[0017] like Figure 2 , 3 As shown, the shallow buried device of the thin-wall drip irrigation belt comprises a frame 1, a mounting roller frame 2 connected to the frame 1, and a guide rotating wheel 3. A connecting rod 4 is fixed to the lower rear part of the frame 1. The bottom of the connecting rod 4 is fixedly connected to a cross bar 5. The cross bar 5 is connected to a block 6. The block 6 is hinged to a fixed plate 7. The end of the fixed plate 7 is fixedly connected to a fixed frame 8. A furrowing plow 9 is fixed to the front of the fixed frame 8. A guide ring mounting column 10 is fixed to the top of the fixed frame 8. A guide ring 11 is fixed to the guide ring mounting column 10. The guide rotating wheel 3 is rotatably connected to the inner wall of the fixed frame 8. A covering plate 12 is hinged to the side wall of the fixed frame 8. The covering plate 12 is formed by bending a plate and has an angle, and the tail is V-shaped.

[0018] Further, a lifting rod 13 is fixed to the fixed frame 8, a counterweight 14 is slidably arranged on the lifting rod 13, a pin hole 19 for positioning the counterweight 14 is arranged on the lifting rod 13, a positioning pin is inserted into the pin hole 19, and the positioning pin blocks and positions the counterweight 14 at a position of the lifting rod 13. The lifting rod 13 and the counterweight 14 use the principle of lever to exert downward pressure on the fixed frame 8 and the furrowing plow 9, and the further the counterweight 14 is positioned, the greater the downward pressure it brings.

[0019] If there is only the guide ring 11, it will be directly connected with the thin-walled drip irrigation belt 20 after coming down from the guide ring 11, and the thin-walled drip irrigation belt 20 will not be able to stick to the ground well. Therefore, a lower guide ring 15 can be provided on the guide ring mounting column 10 close to the fixed frame 8. The lower guide ring 15 and the guide ring mounting column 10 are connected by a movable sleeve, and the open clamp ring is fastened with screws. The inner ring length of the lower guide ring 15 is slightly larger than the width of the thin-walled drip irrigation belt 20 (it is in a strip shape when no water flows, so it can be called width), and the thin-walled drip irrigation belt 20 is restricted, and basically does not swing left and right, so it is applied straight. Thin-walled drip irrigation belts 20 of different widths can be installed with lower guide rings 15 of different inner ring lengths.

[0020] The mounting roller frame 2 is used to mount the thin-wall drip irrigation belt 20. The structure is prior art and belongs to a common structure for collecting and releasing the drip irrigation belt, which will not be described in detail. In order to facilitate the installation of the thin-wall drip irrigation belt 20, a foot pedal 16 is fixed on the frame body 1, and the operator steps on the foot pedal 16 to replace the thin-wall drip irrigation belt 20.

[0021] For small tractors, a three-point suspension frame can be directly welded on the frame 1 and fixed to the tail of the tractor. The tractor can lay 1-3 rows when it moves once. For high-horsepower tractors, more than 7 thin-walled drip irrigation tapes 20 can be laid at the same time, so the length of the frame 1 must be lengthened. After placing the thin-walled drip irrigation tapes 20, the overall weight is large, and the tractor hanging point may not be able to bear the weight. A wheel position 17 can be provided on the frame 1, and the wheel position 17 is used to install the running wheel (existing technology, not shown in the figure). The running wheel plays a supporting role. A hanging bracket is welded in the middle of the frame 1 (existing technology, not shown in the figure) and connected to the tractor. The tractor only plays a pulling role.

[0022] Since the block 6 is hinged with the fixed plate 7, when the device moves on the road, if there is no limiting structure, the fixed plate 7 will naturally sag and drag on the ground, making it impossible to walk. The designer has studied a simple method to save labor and cost. A hanging chain 18 is set, the lower end of the hanging chain 18 is welded to the fixed plate 7, and the upper end is welded to the foot pedal 16 or the rear end of the frame 1.

[0023] The use of the device is as follows: the thin-walled drip irrigation belt 20 is placed on the installation roller frame 2, and one end of the thin-walled drip irrigation belt 20 is pulled out so that it passes through the guide ring 11 and the lower guide ring 15, and then bypasses the bottom of the guide rotating wheel 3. If the thin-walled drip irrigation belt 20 bypassing the guide rotating wheel 3 is laid from the end of the field, the end of the thin-walled drip irrigation belt 20 bypassing the guide rotating wheel 3 is closed and buried in the soil, the tractor is started, the furrowing plow 9 opens a shallow ditch, the thin-walled drip irrigation belt 20 falls to the bottom of the ditch, and the covering plate 12 pushes the soil to cover the thin-walled drip irrigation belt 20 with a layer of soil. If the ground is undulating, the covering plate 12 jumps along the undulation of the soil surface at a certain amplitude, maintains a certain amount of bulldozing, and keeps the covering depth basically unchanged. If the thin-walled drip irrigation belt 20 bypassing the guide rotating wheel 3 is laid from the head of the field, the end of the thin-walled drip irrigation belt 20 bypassing the guide rotating wheel 3 is to be connected to the water pipe, so the end is to be exposed, waiting to be connected to the water pipe joint, and the section in front of the end is buried in the soil, the tractor is started, and the shallow ditch is opened, the thin-walled drip irrigation belt 20 is placed, and the soil is covered in the above manner.
