Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to an adjustable drip irrigation tape mulching and seeding integrated machine. Background Technology

[0002] With global population growth and increasing constraints on arable land resources, modern agriculture is facing an increasingly urgent need for mechanization, precision, and efficiency. In arid, semi-arid, and water-scarce planting areas, how to achieve water-saving irrigation, moisture retention, increased efficiency, and high crop yields through agricultural equipment technology innovation has become a key issue for the industry's development. Against this backdrop, drip irrigation technology and mulch film technology have been widely used in the planting of grains, vegetables, and cash crops due to their significant advantages in water conservation, heat preservation, and weed suppression.

[0003] Currently, drip irrigation tape laying usually requires separate operation. It involves first digging trenches, laying the tape, and burying it, and then other equipment is used to complete the sowing and mulching. This process results in machinery entering the field multiple times, which not only increases energy consumption and labor costs, but also easily affects crop growth due to soil compaction. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable drip irrigation tape mulching and seeding integrated machine to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable drip irrigation tape mulching and seeding integrated machine includes a frame, a seeding mechanism in the middle of the frame, a mulching mechanism on the right side of the frame, and multiple sets of linearly distributed drip irrigation tape laying mechanisms.

[0007] The drip irrigation tape laying mechanism includes a unwinding wheel rotatably mounted on the left side of the frame, on which drip irrigation tape is wound. A mounting base is mounted on the lower side of the frame, and a strip rod is hinged to the mounting base. A tension spring is provided between the middle of the strip rod and the mounting base. The strip rod has a through-hole for laying drip irrigation tape. A furrow opener is provided at the lower end of the strip rod. A burying device is also connected to the end of the strip rod. The burying device consists of two inclined discs arranged in a V-shape.

[0008] An adjusting plate is connected to the end of the tension spring. The adjusting plate has multiple mounting holes. A mounting block that matches the mounting holes is fixed in the middle of the strip rod.

[0009] The end of the bar is fixed with a base, the burial device is connected to a U-shaped connecting seat, the U-shaped connecting seat rotates on the base via a rotating shaft, and a torsion spring is provided between the rotating shaft and the base.

[0010] A crossbar is fixed to the lower side of the frame, and a sliding sleeve is slidably installed on the crossbar. The mounting base is fixed to the lower side of the sliding sleeve, and an adjustment component is provided between the sliding sleeve and the crossbar.

[0011] The adjusting assembly includes a threaded through hole in the sliding sleeve, and a fixing bolt is threaded into the threaded through hole, with the end of the fixing bolt abutting against the crossbar.

[0012] The sliding sleeve is equipped with guide wheels.

[0013] This application integrates the three core processes of sowing, drip irrigation tape laying, and mulching into a single frame. By using a mobile vehicle to pull it, all three processes can be completed in one operation, reducing the number of times manual labor and machinery need to repeatedly enter the field, thus saving time and costs.

[0014] This application adjusts the soil penetration depth of the furrow opener by changing the connection position of different mounting holes on the adjustment plate with the strip rod, thereby achieving precise control of the drip irrigation tape laying depth. Attached Figure Description

Detailed Implementation

[0022] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-4 As shown, the present invention provides an adjustable drip irrigation tape mulching and sowing integrated machine, including a frame 1, a sowing mechanism 11 in the middle of the frame 1, a mulching mechanism 12 on the right side of the frame 1, and multiple sets of linearly distributed drip irrigation tape laying mechanisms.

[0024] The drip irrigation tape laying mechanism includes a frame 1 with a reel 2 rotatably mounted on the left side, on which drip irrigation tape is wound. A mounting base 21 is mounted on the lower side of the frame 1. A strip rod 22 is hinged to the mounting base 21. A tension spring 23 is provided between the middle of the strip rod 22 and the mounting base 21. A through drip irrigation tape laying channel 24 is opened on the strip rod 22. A furrow opener 25 is provided at the lower end of the strip rod 22. A burying device 26 is also connected to the end of the strip rod 22. The burying device 26 is composed of two inclined discs arranged in a V-shape.

[0025] The frame 1 of this application is connected to a mobile vehicle, which moves the frame 1 in the farmland. The seeding mechanism 11 is used to achieve automatic seeding, the drip irrigation tape laying mechanism is used to automatically lay the drip irrigation tape, and the mulching mechanism 12 is used to cover the film. The mulching can keep the soil warm, retain moisture, inhibit the growth of weeds, and reduce water evaporation, thus creating a favorable environment for crop growth.

[0026] The seeding mechanism and the mulching mechanism are existing technologies, and this application does not improve upon them. The basic principles of the seeding mechanism and the mulching mechanism are now explained:

[0027] A typical sowing mechanism includes a seed box (a container for storing seeds, usually equipped with a seed dispensing adjustment device to control the amount of seeds sown per unit area), a seed metering device (the core component of sowing, which uses the rotation of a perforated wheel, a mortise wheel, or a spoon wheel to grab and discharge seeds at fixed intervals), a seed delivery tube (connecting the seed metering device and the furrow opener to guide the seeds to fall precisely into the furrows), and a furrow opener (which opens sowing furrows in the soil).

[0028] Working principle: The seeds in the seed box are discharged at set intervals and in set quantities by the rotation of the seed metering device. The furrow opener draws furrows as it moves forward, and the seed delivery tube accurately puts the seeds into the bottom of the furrows.

[0029] The mulching system includes a mulch film roll support (to fix the mulch film roll, usually equipped with a tension adjustment device to prevent the mulch film from stretching or loosening), a film spreading roller (to spread the mulch film by rotation or friction to ensure flat laying), and a film pressing roller (to press the edges of the mulch film into the soil to prevent it from being blown away by the wind or shifting).

[0030] Working principle: The plastic film roll rotates under the action of traction force, and the film spreading roller or friction force lays the plastic film flat on the ground. The film pressing roller presses the two sides of the plastic film into the trench or soil to form a preliminary fixation.

[0031] This application includes a drip irrigation tape laying mechanism between the sowing mechanism and the mulching mechanism for laying the drip irrigation tape. Its working principle is as follows:

[0032] The drip irrigation tape is wound around the unwinding reel 2 and passed through the drip irrigation tape laying channel 24 of the strip rod 22. During the laying process, the moving vehicle drives the frame 1 to move. Under the elastic force of the tension spring 23, the trench opener 25 connected to the lower end of the strip rod 22 will be inserted into the ground. The movement of the frame 1 can drive the trench opener 25 to open a trench in the land, and the drip irrigation tape will be laid in the trench. The burying device 26 can push the soil on both sides of the trench back into the trench to bury the drip irrigation tape, thus realizing the automatic laying of the drip irrigation tape.

[0033] The burying device 26 consists of two inclined discs arranged in a V-shape. The discs can gather the soil on both sides of the ditch towards the center, thereby achieving the effect of burying the drip irrigation tape.

[0034] The end of the tension spring 23 is connected to an adjusting plate 231, which has multiple mounting holes 232. The middle of the strip rod 22 is fixed with a mounting block 221 that matches the mounting holes 232. By inserting different mounting holes 232 on the adjusting plate 231 into the mounting block 221, the force exerted by the pull ring 23 on the strip rod 22 is changed, which can adjust the downward distance of the furrow opener 25 of the strip rod 22, that is, adjust the depth of the drip irrigation tape.

[0035] A fixed base 222 is fixed to the end of the strip rod 22, and a U-shaped connecting base 261 is connected to the burial device 26. The U-shaped connecting base 261 rotates on the fixed base 222 via a rotating shaft 262. A torsion spring 263 is provided between the rotating shaft 262 and the fixed base 222. One end of the torsion spring 263 is connected to the rotating shaft 262, and the other end is connected to the fixed base 222. When an external force is applied to make the burial device 26 rotate, that is, the rotating shaft 262 rotates, which will cause the torsion spring 263 to twist. When the burial device 26 is not subjected to external force, the elastic force of the torsion spring 263 can drive the burial device 26 to reset. In this way, under the elastic force of the torsion spring 263, the burial device 26 can always face downward and be in contact with the soil, which can bury the drip irrigation tape in actual use.

[0036] A crossbar 3 is fixed on the lower side of the frame 1. A sliding sleeve 31 is slidably installed on the crossbar 3. The mounting base 21 is fixed on the lower side of the sliding sleeve 31. An adjustment component is provided between the sliding sleeve 31 and the crossbar 3.

[0037] The adjusting assembly includes a threaded through hole in the sliding sleeve 31, and a fixing bolt 32 is threadedly connected to the threaded through hole. The end of the fixing bolt 32 abuts against the crossbar 3.

[0038] The sliding sleeve 31 can be fixed to the crossbar 3 by abutting against the crossbar 3 through the fixing bolt 32. When adjusting the position of the strip bar 22, simply turn the fixing bolt 32 so that its end is not abutting against the crossbar 3, and the sliding sleeve 31 can be slid to change the overall position of the strip bar 22. Then turn the fixing bolt 32 in the opposite direction so that its end abuts against the crossbar 3. This design can adjust the position of the drip irrigation tape and is more practical.

[0039] The sliding sleeve 31 is equipped with a guide wheel 33; the guide wheel 33 makes the drip irrigation tape slide more smoothly from the unwinding wheel 2 into the drip irrigation tape laying channel 24 inside the strip rod 22.

[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
