Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting technology, and specifically relates to an integrated device for mulching and drip irrigation. Background Technology

[0002] In modern agriculture, mulching and drip irrigation are two widely used technologies. Mulching provides insulation, moisture retention, and weed control, while drip irrigation enables precise irrigation, significantly conserving water resources. Traditionally, the laying of mulch and drip irrigation pipes is done in two separate steps: first, the drip irrigation pipes are laid manually or mechanically, and then the mulch is laid manually or by another machine. This step-by-step approach has significant drawbacks: first, it requires repeated fieldwork, increasing the number of times the machinery compacts the soil and damaging its structure; second, it is inefficient, requiring more labor and time, increasing production costs; and finally, the step-by-step laying makes it difficult to ensure the accuracy and consistency of the drip irrigation pipes' position relative to the mulch, potentially affecting the uniformity of subsequent irrigation. Utility Model Content

[0003] The purpose of this utility model is to provide an integrated device for film covering and drip irrigation.

[0004] This utility model is achieved through the following measures: a film-coating and drip-laying integrated device, characterized in that it includes a box for holding a drip roll, the two side walls of the box are provided with a clamping structure for the drip roll, a push rod is fixedly provided at one end of the box, and extension plates are symmetrically provided on both sides of the other end of the box. An ear plate is fixedly provided below the outer end of the extension plate, and a swing rod is rotatably provided on the ear plate. The other ends of the two swing rods are fixedly connected by a connecting plate. It also includes two sliding sleeves that are slidably disposed on the connecting plate, a plastic film roll is disposed between the two sliding sleeves, and at least one screw is provided on the sliding sleeve by means of a threaded connection; A drip outlet is provided on the lower part of the inner wall of the box body near the mulch film roll; Wheels are rotatably mounted on the outer sides of both sides of the box via fixed frames, and the wheels are located outside the swing arm. By integrating the drip irrigation roll box, the mulch film laying mechanism with adjustable sliding sleeves, and the wheels into a single device, drip irrigation pipe laying and mulch film covering can be completed simultaneously in a single operation. The rotatable connection of the swing arm allows the mulch film roll to better adapt to uneven ground under the action of gravity.

[0005] Furthermore, the clamping structure includes a screw, one end of which is rotatably provided with a dropper conical limiting cylinder via a bearing; The screw is threaded through the side wall of the housing, and the dropper conical limiting cylinder is located inside the housing with its small end facing the dropper reel. By rotating the screw, the conical limiting cylinder can be driven to press against the inner hole of the dropper reel, realizing the clamping and centering of dropper reels with different inner diameters. The dropper conical limiting cylinder is equipped with a bearing to provide smooth rotation of the reel.

[0006] Furthermore, a handwheel is fixedly provided at the outer end of the screw.

[0007] Furthermore, the upper part of the side wall of the box is provided with an outer protrusion, and the outer protrusion is provided with a groove for placing the dropper conical limiting cylinder. The groove is connected to the interior of the box. When the dropper conical limiting cylinder is not needed or is retracted, the groove can serve as a storage position for the dropper conical limiting cylinder, avoiding interference with the installation of the dropper reel.

[0008] Furthermore, a guide wheel is rotatably disposed between the two side walls of the dropper outlet, and the guide wheel is provided with an annular groove for placing the dropper. The dropper passes through the annular groove of the guide wheel, changing sliding friction into rolling friction, effectively reducing the traction resistance of the dropper at the outlet and preventing the dropper from wearing or deforming due to excessive friction.

[0009] Furthermore, the drip outlet is located in the middle of the box. By setting the outlet in the middle of the box, the drip irrigation pipe is led out from the center line of the device and kept in line with the direction of travel of the device, thereby ensuring that the drip irrigation pipe is accurately laid at the predetermined position on the ground as much as possible.

[0010] Furthermore, an installation rod is fixedly mounted on the front end of the sliding sleeve. The installation rod is parallel to the swing arm and has a fixed shaft fixedly mounted on its inner side. A mulch film conical limiting cylinder is rotatably mounted on the fixed shaft via a bearing, with the small end of the mulch film conical limiting cylinder facing the mulch film roll. Through the mulch film conical limiting cylinder and the installation rod, etc., rapid and stable clamping and center positioning of mulch film rolls with different inner diameters are achieved.

[0011] Furthermore, both the drip tube conical limiting cylinder and the mulch film conical limiting cylinder include a cylinder and a concentric concentric ring. The small end of the conical ring is fixedly connected to one end of the cylinder, and the large end is fixedly connected to the cylinder through several support rods. Bearings are provided at both ends of the cylinder.

[0012] Furthermore, the fixing frame includes fixing rods symmetrically arranged on the outer wall of the box, the outer ends of the two fixing rods are connected by a mounting plate, and the wheel is rotatably arranged on the outside of the mounting plate.

[0013] Furthermore, the box is generally a rectangular box that is sealed at the bottom and open at the top.

[0014] How to use: Place the drip irrigation reel into the housing, rotate the handwheels on both sides to move the drip irrigation conical retainer inward until it is firmly inserted into the inner hole of the reel, securing it securely. Insert the mulch film reel between the two sliding sleeves, sliding the sleeves to allow the mulch film conical retainer to press against the two end faces of the mulch film reel. Then tighten the screws on the sliding sleeves to fix them to the connecting plate. Pull the end of the drip irrigation pipe from the reel inside the housing, around the guide wheel, and extend it a certain length from the drip outlet, fixing it at the starting end in the field. Pull the end of the mulch film from the mulch film reel and bury it at the starting end in the field. The operator holds the push rod and pushes forward or pulls the device from the front. The wheels roll, propelling the entire device forward. As the device moves forward, the drip irrigation reel and mulch film reel rotate, continuously and synchronously releasing the drip irrigation pipe and mulch film. The drip irrigation pipe is laid on the ground through the central drip outlet, and the mulch film is then placed over the drip irrigation pipe. During installation, the swing arm structure allows the mulch film laying components to sway slightly with the terrain, maintaining a good ground contact. Upon reaching the end of the field, the drip irrigation pipe and the end of the mulch film are cut and secured, completing the laying operation for that section. When it is necessary to change the roll, the screw and sleeve can be reversed for a quick replacement.

[0015] The beneficial effects of the technical solution provided by this utility model embodiment are: it realizes the simultaneous integrated operation of drip irrigation pipe laying and mulch film covering, fundamentally solving the problems of low efficiency, high cost, soil compaction, and inaccurate laying position that exist in traditional step-by-step operations. Through the adjustable conical limiting cylinder and sliding sleeve structure, it ensures that the drip irrigation pipe roll and mulch film roll are firmly clamped and rotate smoothly under various specifications. The centered design of the drip outlet combined with the guide wheel mechanism ensures that the drip irrigation pipe is laid straight and accurately positioned, and effectively prevents drip pipe wear. The floating design of the swing arm connection allows the mulch film laying component to better adapt to terrain undulations, ensuring the fit of the mulch film covering. This application adopts manual drive, reducing the overall weight and avoiding the high cost of large equipment, and is well-suited for individual growers. Attached Figure Description

The groove 9 is connected to the interior of the box 1. When the dropper conical limiting cylinder 302 is not needed or is retracted, the groove 9 can be used as a storage position for the dropper conical limiting cylinder 302 to avoid affecting the installation of the dropper roll 2.

[0024] A guide wheel 11 is rotatably mounted between the two side walls of the dropper outlet 103. The guide wheel 11 has an annular groove 9 for placing the dropper.
