Description

Technical Field

[0001] The present invention belongs to the technical field of modern agricultural sowing and mulching devices, and in particular relates to a planting device with dual functions of intercropping sowing and laying ground film. Background Art

[0002] Most agricultural seeding machines have a single seeding type and require collaborative operation between humans and machines. The process is relatively cumbersome. In addition, most mulch-laying machines are not fully automated and require manual cutting and soil compaction, and cannot be well matched with seeding machines.

[0003] Existing seed-metering devices mainly include air-suction precision seed-metering devices and roller-type seed-metering devices with replaceable molds. Among them, the advantage of the air-suction precision seed-metering device is that the seeding quantity is uniform and the seeding spacing is highly accurate; the disadvantage is that it is difficult or impossible to replace the mold, the power loss is huge, and the cost is very high. The advantage of the roller-type seed-metering device with replaceable molds is that the mold can be replaced and different types of seeds can be sown, and the cost is low; the disadvantage is that the seeding quantity is uneven, the seeding spacing fluctuates greatly, and precision sowing cannot be achieved. At the same time, existing agricultural machines are mainly special seeding machines for a single crop and ground film laying machines; the advantage of special seeding machines for a single crop is that they are highly targeted and have better sowing effects for the corresponding crops; the disadvantage is that they have a single function and a low frequency of use; the advantage of ground film laying machines is that they save manpower and improve work efficiency; the disadvantage is that they require human cooperation throughout the process and have a low degree of automation. Therefore, the present invention proposes a planting device with the dual functions of intercropping sowing and laying ground film, with the aim of overcoming the shortcomings of the prior art.

The rolling wheel 556 and the side soil blade 557 are both supported on the rolling wheel bracket 555, and the side soil blade 557 is located on the outside of the rolling wheel 556.

[0046] The specific operation steps of the present invention are as follows:

[0047] like Figures 1 to 13 As shown, the present invention provides a planting device with the dual functions of intercropping sowing and laying ground film. When working, the specific principle is as follows: the lower side of the seed disc rotating square shaft 39 is connected to the output shaft of the seeding motor, and the upper groove plate 33 and the rotating seed disc 32 are driven by the seeding motor to rotate together. A fixed disc 323 is attached to the center of the rotating seed disc 32, and a compression spring 35 is installed around it. The compression spring 35 can push the seed clamp 34. The tail of the seed clamp 34 is connected to the seed clamp limiting column 342. When the seed clamp 34 moves to the seed storage tank 38, the movable adjustment plate 36 itself can block the seed clamp limiting column 342, thereby blocking the compression spring 35 from pressing the seed clamp 34. The outer end of the seed clamp slideway 321 on the rotating seed disc 32 cannot be completely closed by the push of the movable adjustment plate 36, and the seeds in the seed storage tank 38 can fall into the outer end of the seed clamp slideway 321. When the seed clamp 34 moves beyond the range of the movable adjustment plate 36, the seed clamp 34 firmly clamps the seeds under the push of the compression spring 35. When the seed clamp 34 moves to the area of ​​the inner adjustment plate 372, the inner adjustment plate 372 inside the seed metering device upper cover 37 will block the seed clamp 34 from returning again, and the outer end of the seed clamp slideway 321 will open again, releasing the seeds. A seed metering device outlet 311 is provided below the seed metering device base plate 31, and the seeds will flow to the seed metering conversion plate 2. At the same time, the size of the opening and closing of the groove end of the rotating seed disc 32 is controlled by controlling the gear position of the movable adjustment plate 36, thereby accommodating seeds of different sizes to flow into the slideway through hole 322.

[0048] The seeds discharged by the rotary clamping seeding unit 3 flow into the seeding conversion plate 2 and then enter the seeding hose. The seeding hose is connected to the furrowing tool 44 below through the intermediate conversion plate 12. The three lateral moving modules 41 respectively control the seeding row spacing of the three seeding channels. The lateral moving module 41 can accurately adjust the row spacing. The furrowing tool 44 is connected to the vertical lifting module 42, which can accurately adjust the height and furrowing depth of the furrowing tool 44. It is fixed on the vertical lifting module 42 at the same time as the covering wheel 43 through the connecting plate. The covering wheel 43 can effectively squeeze the soil on both sides of the furrow to close the furrow. When the seed conversion disc 2 is used for intercropping sowing, when the three rotating clamping seeding units 3 above discharge two different seeds, such as the seed categories of the three channels are AAB, when the machine finishes sowing one row and turns back to sow the next row, the machine turns back to sow and becomes BAA. At this time, the seed conversion disc 2 can be controlled to rotate, so that the seeds flowing into the three pipes of the rotating clamping seeding units 3 are converted. At this time, the machine sowing becomes back to AAB, ensuring that the regular order of intercropping crops in the fields remains unchanged.

[0049] At the rear of the machine is the film covering unit 5. The ground film 6 is supported by the ground film support module 51. The support base 511 of the ground film 6 is provided with multiple adjustment holes 515, which can be used to adjust the specific position of the ground film 6. When only the first two rows are laid and the third row is not laid, the right ground film support module 51 can be installed in the adjustment hole 515 on the left side. Two ground film conveying shafts 52 are installed under the ground film 6. Driven by the motor, the two ground film conveying shafts 52 rotate inward simultaneously, which can automatically pull the ground film downward. When the ground film reaches the ground, another 0.5m of ground film is conveyed and scattered on the ground. At this time, the machine moves forward. The rolling wheels 556 behind the ground film will compress the ground film. The side soil blades 557 on both sides will raise the soil on both sides of the ground film, covering the sides of the ground film and pushing a small amount of soil into the rolling wheels 556. The rolling wheels 556 will intermittently drop soil into the center of the ground film to cover the ground film. After the machine has laid a row of ground film, the ground film is in a taut state. Under the action of the ground film limiting optical axis 53, the ground film is stretched between the ground film limiting optical axis 53 and the ground film conveying counter-axis 52 near the ground film cutting module 54. Multiple short connecting rods 542 and long connecting rods 543 in the ground film cutting module 54 form a parallelogram mechanism. At this time, the parallelogram mechanism drives multiple cutting blades 544 to cut the ground film under the drive of the motor. After the ground film is cut off, the entire covering module 55 is lifted under the action of the lifting drive 553, and the machine turns to sowing and laying the next row of land, and then repeats the above process to realize full automation of laying ground film.
