[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0025] The following is in conjunction with the appendix Figure 1-3 To further describe this application in detail, this utility model is an underground drip irrigation tape laying device capable of spraying pesticides, including a traction support frame 1 connected to a walking device. The upper part of the traction support frame 1 is connected to a drip irrigation tape placement unit for placing the drip irrigation tape. The rear part of the traction support frame 1 is provided with a trenching unit for digging trenches in the soil to facilitate the placement of the drip irrigation tape. The trenching unit is connected to a tape laying and soil covering unit for placing the drip irrigation tape underground and covering the top of the drip irrigation tape with soil through a connecting plate 2. The rear part of the tape laying and soil covering unit is provided with a pesticide spraying unit. The walking device described in this utility model can be a power device such as an electric tricycle or agricultural tractor. By setting a spraying unit at the rear of the underground drip irrigation tape laying device, it is possible to spray pesticides directly after laying the underground drip irrigation tape, thus changing the traditional method of laying the underground drip irrigation tape first and then spraying pesticides. This avoids the problem of irreversible damage to the underground drip irrigation tape caused by subsequent herbicide spraying and enables the laying of underground drip irrigation tape after the year. This utility model uses a trenching unit to open trenches in the land, laying the foundation for subsequent drip irrigation tape laying. The drip irrigation tape placement unit is used to store the drip irrigation tape, laying the foundation for continuous laying of the drip irrigation tape. The tape placement and soil covering unit can place the drip irrigation tape from the drip irrigation tape placement unit into the trenches opened in the aforementioned trenching operation, and can also cover the placed drip irrigation tape with soil. Furthermore, by setting up a spraying unit, weed and pest control can be carried out on the planted plots after the soil covering operation. In other words, this utility model can realize automatic trenching, pipe laying, burial, soil covering, and pesticide spraying operations, thereby improving the efficiency of underground drip irrigation tape laying.
[0026] Furthermore, the drip irrigation tape placement unit includes a drip irrigation tape support frame 3, which is fixedly connected to a traction support frame 1. The drip irrigation tape support frame 3 has several drip irrigation tape winding sections. The traction support frame 1 is fixedly connected to the drip irrigation tape support frame 3, enabling it to move simultaneously. The number of drip irrigation tape winding sections is related to the length of the drip irrigation tape support frame 3 and the width of the field operation, and can be adjusted according to specific conditions. Preferably, the drip irrigation tape winding sections are evenly distributed on the drip irrigation tape support frame 3. Further, preferably, several drip irrigation tape winding sections are movably mounted on the drip irrigation tape support frame 3.
[0027] Furthermore, the drip irrigation tape winding part includes a drip irrigation tape winding wheel 4, with drip irrigation tape 5 wound around its outer circumferential surface. The interior of the drip irrigation tape winding wheel 4 is connected to the drip irrigation tape support frame 3 via a bearing 6. The drip irrigation tape winding wheel 4 described in this invention is used to wind the drip irrigation tape 5 for convenient storage. During use, the drip irrigation tape support frame 3 does not rotate, while the drip irrigation tape winding wheel 4 rotates, and the drip irrigation tape is released during this rotation. The specific process of releasing the drip irrigation tape is as follows: the tape-covering unit covers and compacts the drip irrigation tape placed in the field, while the walking device continues to move forward, thereby achieving the rotation of the drip irrigation tape winding wheel 4.
[0028] Furthermore, the trenching unit and the drip irrigation tape winding part are configured in a one-to-one correspondence. The trenching unit includes a trenching frame 7, with a trenching frame sleeve 8 on the outer circumferential surface of the trenching frame 7. A connecting piece 9 is provided on the outside of the trenching frame sleeve 8, and a hole is opened in the middle of the connecting piece 9. A screw 10 is inserted into the hole, and a spring 11 is provided on the outer circumference of the screw 10. A locking nut 12 is provided on the top of the spring 11, and a trenching cutter 13 is provided on the bottom of the screw 10. In this utility model, the trenching unit and the drip irrigation tape winding part are in a one-to-one correspondence, that is, the trenches opened by the trenching unit are prepared for laying the drip irrigation tape. In the actual laying process, it is necessary to ensure that the trenching depth is consistent, so as to ensure the laying effect of the underground drip irrigation tape. Based on this, this utility model is equipped with a buffer and shock absorption device. The trenching depth of the trenching cutter 13 is adjusted by the locking nut 12, and the spring 11 is used to buffer and absorb the shock of the trenching cutter 13, thereby achieving the characteristics of adjustable trenching depth and basically consistent trenching depth.
[0029] Furthermore, the drip irrigation tape covering unit includes a covering support 14 connected to the connecting plate 2. A covering section is provided on the rear side of the covering support 14, and a drip irrigation tape passage hole 15 is provided on the corresponding front part of the covering support 14. The covering section, the drip irrigation tape passage hole 15, and the drip irrigation tape winding section are arranged in a one-to-one correspondence. Through this one-to-one correspondence, the drip irrigation tape can smoothly enter the trench after the trenching unit has opened, and then be covered and compacted with soil. This covering and compaction not only covers the drip irrigation tape with soil but also allows the drip irrigation tape winding wheel 4 to rotate.
[0030] Furthermore, the soil covering section includes a soil covering support 16 connected to the soil covering bracket 14 and disposed on both sides of the drip irrigation tape passage hole 15. The end of the soil covering support 16 is provided with a through-shaft 17, and the middle of the through-shaft 17 is provided with a rotatable soil covering and compaction wheel 18. Scrapers 19 are provided at both ends of the through-shaft 17, and the two scrapers 19 are inclined from front to back towards the soil covering and compaction wheel 18. The two scrapers 19 can gather the soil after trenching, and on the basis of gathering, the soil covering and compaction wheel 18 is used to compact the soil.
[0031] Furthermore, the spraying unit includes a spray bar 20 connected to the end of the spraying connecting plate 22, and nozzles 21 are evenly distributed on the spray bar 20; the first end of the spraying connecting plate 22 is connected to the soil covering support 14. In this invention, the spray bar 20 is connected to the nozzles 21 to achieve spraying in the field; on the other hand, it can be connected to a pesticide tank using a flexible hose, and the pesticide tank can be placed on a power unit such as an electric tricycle or agricultural tractor.
[0032] The specific working process of this utility model is as follows: The traction support frame 1 is installed on a walking device such as an electric tricycle or agricultural tractor. The agricultural tractor or electric tricycle pulls the vehicle at a constant speed. During the movement, the ditching blade 13 performs ditching operations. Before ditching, the ditching depth can be adjusted by tightening the locking nut 12 in conjunction with the pressure of the spring 11. At the same time, the spring 11 also plays a role in buffering and shock absorption. The preferred ditching depth is 150-200mm, and the ditching width is 100mm. The drip irrigation tape 5 on the drip irrigation tape winding wheel 4 is laid in the aforementioned ditch through the drip irrigation tape through hole 15. It is necessary to ensure that the drip irrigation tape 5 is positioned below the soil compaction wheel 18. Two scrapers 19 can gather the soil after trenching, and the soil compaction wheel 18 is used to compact the soil, burying the drip irrigation tape 5 10-15cm below the surface. Simultaneously, during this process, the pesticide from the pesticide tank enters the nozzle 21 via the hose and spray bar 20, and is sprayed by the nozzle 21. This process enables automatic trenching, pipe laying, burial, soil covering, and pesticide application, significantly improving the efficiency of drip irrigation tape installation and allowing for underground drip irrigation tape installation after the New Year. The drip irrigation tape 5 described in this invention preferably uses a patch-type or inlaid patch-type drip irrigation tape with good anti-clogging properties, a working pressure greater than 10m, a flow rate greater than 3L / h, and a dripper spacing of 30-40cm.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
