Description

Technical Field

[0001] The invention belongs to the field of agricultural film laying machines, and particularly relates to an integrated machine for ridge forming, film laying and hole punching operations in saline-alkali land. Background Art

[0002] Research shows that slightly saline water (with a salinity of 2 - 5 g / L) can replace fresh water resources for agricultural irrigation. Especially when irrigating during the non-sensitive period of crops to slightly saline water, stable and high yields can be achieved. For example, the flowering period of peanuts, the second node period of soybeans, and the jointing period of wheat are all non-sensitive periods to slightly saline water. Slightly saline water resources are widely distributed in China. Using slightly saline water for irrigation during the sensitive period of crops will affect the normal growth and development of crops, and even affect the normal emergence of crops, resulting in a reduction in yield. If fresh water is used for irrigation, the conventional method is to desalinate a large amount of slightly saline water outside the plot and use fresh water for irrigation throughout the growth period, which will cause too high planting costs and waste a large amount of fresh water.

[0003] If the traditional irrigation methods of drip irrigation or flood irrigation are adopted after laying plastic films in saline-alkali land using ordinary film laying machines, and the slightly saline water still needs to be specifically desalinated outside the plot during the sensitive period of crops to slightly saline water, the irrigation cost remains high. Therefore, there is an urgent need for a film laying machine that can improve the form of film laying, and cooperate with plastic films and slightly saline water to irrigate crops sufficiently and reasonably, ensuring the normal development of crops, increasing crop yields, and reducing irrigation costs at the same time. Summary of the Invention

[0004] In order to solve the problems existing in the above-mentioned prior art, the invention provides an integrated machine for ridge forming, film laying and hole punching operations in saline-alkali land, which can simultaneously complete ridge forming, film laying and seeding operations in a saline-alkali land plot, and form an irrigation channel for making full and reasonable use of slightly saline water irrigation between plastic films, ensuring the normal growth of crops while reducing the workload and irrigation costs.

[0005] The specific technical solution adopted by the invention is as follows:

[0006] An integrated machine for ridge forming, film laying and hole punching operations in saline-alkali land includes a frame connected to a tractor and an operation shaft arranged on the frame. The operation shaft includes, in reverse order along the traction direction, a shaping roller for ridge forming, a first film spreading roller for laying the first plastic film, a film shaping roller, an insert type seeder, a rope releasing roller, and a second film spreading roller for laying the second plastic film. A set of first shaping discs are arranged at intervals on the shaping roller. A second shaping disc corresponding to the first shaping disc is arranged on the film shaping roller. The second plastic film is located above the first plastic film. A set of rope shafts located between adjacent ridges are arranged on the rope releasing roller. The rope on the rope shaft is located between the first plastic film and the second plastic film and is used to support the second plastic film to make the second plastic film in a wavy structure. The trough of the second plastic film corresponds to the insert type seeder.

[0007] A grooving roller is arranged between the integer roller and the first film spreading roller. A group of third shaping discs respectively corresponding to the first shaping discs are arranged on the grooving roller, and annular grooving protrusions corresponding to the ridges are arranged between the third shaping discs. The end part of the annular grooving protrusion is lower than the upper surface of the ridge. The annular grooving protrusion, the plug-in seeder, and the trough of the second plastic film are arranged in alignment along the traction direction.

[0008] A grooving roller is arranged between the integer roller and the first film spreading roller. A group of third shaping discs respectively corresponding to the first shaping discs are arranged on the grooving roller, and strip-shaped grooving protrusions parallel to the grooving roller and penetrating through the third shaping discs are arranged. The end part of the strip-shaped grooving protrusion is lower than the upper surface of the ridge. The strip-shaped grooving protrusions are arranged in an array along the grooving roller. A perforator matched with the strip-shaped grooving protrusion is arranged between the first film spreading roller and the second film spreading roller, and the perforator is arranged corresponding to the side of the ridge.

[0009] The perforator is arranged on the plastic film shaping roller and at the junction of the second shaping disc and the plastic film shaping roller.

[0010] A plastic film supporting roller is arranged between the first film spreading roller and the plastic film shaping roller, and the plastic film supporting roller is located between the ridge and the first plastic film.

[0011] The plug-in seeder is a duckbill wheel disc seeder.

[0012] The beneficial effects of the present invention are as follows:

[0013] In the present invention, a technical solution of arranging a first film spreading roller, a plastic film shaping roller, a plug-in seeder, a rope releasing roller, and a second film spreading roller on a frame is adopted, so that a groove located between adjacent two ridges is formed on the first plastic film. The groove is used for storing slightly saline water. During the seeding process of the plug-in seeder, holes are opened on the first plastic film. The second plastic film forms a wavy structure by means of the rope on the rope releasing roller, and the trough is located above the holes opened by the plug-in seeder on the first plastic film. The first plastic film and the second plastic film form a desalination treatment mechanism for slightly saline water. The slightly saline water in the groove formed by the first plastic film condenses into fresh water on the second plastic film through evaporation, and the fresh water drips into the holes opened by the plug-in seeder on the first plastic film along the trough of the second plastic film, providing fresh water for the seeding position of the crop and ensuring the normal development of the crop when it is in the sensitive period of slightly saline water. When the crop is in the non-sensitive period of slightly saline water, the water level of the slightly saline water in the groove formed on the first plastic film can be increased, so that the slightly saline water floods into the first plastic film to irrigate the crop. Through the design of the working shaft, the operation integrated machine can simultaneously ridging, lay the film, and form a new irrigation structure in the saline-alkali land, providing structural support for the new irrigation mode. It can realize the irrigation of fresh water and a large amount of slightly saline water for the crop in stages without performing desalination treatment of slightly saline water outside the plot, which is helpful for the normal growth and development of the crop, improves the crop yield, saves time and effort, and can prevent waste of resources.

Detailed Description of the Preferred Embodiments

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0020] Specific embodiments are as Figures 1-4 shown. A film laying and hole punching operation machine for saline-alkali land includes a frame 10 connected to a tractor 9 and a working shaft disposed on the frame 10. The working shaft includes, in reverse order along the traction direction, a shaping roller 1 for forming a ridge 11, a first film spreading roller 2 for laying a first plastic film 201, a film shaping roller 3, an inserted seeder 4, a rope releasing roller 5, and a second film spreading roller 6 for laying a second plastic film 601. A set of first shaping discs 101 are spaced apart on the shaping roller 1. A second shaping disc 301 corresponding to the first shaping disc 101 is provided on the film shaping roller 3. The second plastic film 601 is located above the first plastic film 201. A set of rope shafts 501 located between adjacent ridges are provided on the rope releasing roller 5. The rope body 502 on the rope shaft 501 is located between the first plastic film 201 and the second plastic film 601 and is used to support the second plastic film 601 to make the second plastic film 601 have a wavy structure. The trough of the second plastic film 601 is correspondingly arranged with the inserted seeder 4. The working shaft may further include a rotary tillage shaft disposed on the frame 10. The rotary tillage shaft is located between the shaping roller 1 and the tractor 9 and is used for rotary tillage of the soil before forming the ridge 11.

[0021] The integer roller 1 and the first shaping disc 101 arranged thereon shape the soil to form ridges 11 higher than the ground; the first film spreading roller 2 unfolds the first plastic film 201 along the ridges 11, and the film shaping roller 3 and the second shaping disc 301 arranged thereon shape the first plastic film 201, so that the first plastic film 201 is laid along the shape on the ridges 11 and the ground, reducing the evaporation amount of water in the plot. The first plastic film 201 forms grooves between adjacent ridges 11; the inserted seeder 4 penetrates the first plastic film 201 and inserts into the ridges 11 for seeding operations; the rope laying roller 5 lays the rope body 502 between the ridges 11, and the second film spreading roller 6 unfolds the second plastic film 601. By setting mounting frames at both ends of the plot, both ends of the rope body 502 are respectively connected to the mounting frames, lifting the second plastic film 601 and making the second plastic film 601 in a wavy structure. The staff can directly discharge the slightly saline water into the grooves formed by the first plastic film 201 to prevent the slightly saline water from seeping into the soil in the plot. The second plastic film 601 covers the first plastic film 201, further reducing the evaporation amount of water in the plot; when the crop is in the sensitive period of slightly saline water, the slightly saline water in the grooves formed by the first plastic film 201 evaporates and condenses on the lower surface of the second plastic film 601 to form fresh water droplets. As the condensation amount increases, the condensed water droplets slide along the wavy second plastic film 601 to its trough and drip into the holes opened on the first plastic film 201 during seeding by the inserted seeder 4, providing fresh water for the crops in the sensitive period of slightly saline water and ensuring the normal emergence and growth of the crops; when the crop is in the non-sensitive period of slightly saline water, the water demand for the growth of the crop becomes larger. At this time, a large amount of slightly saline water can be injected into the grooves formed by the first plastic film 201, so that the slightly saline water overflows the first plastic film 201 on the top of the ridges 11. The slightly saline water contacts the ridges 11 through the holes opened on the first plastic film 201 during seeding by the inserted seeder 4, and the soil absorbs the slightly saline water to provide sufficient water for the crops. With the use of a film laying and hole punching operation machine for saline-alkali land in this embodiment, it can provide an irrigation mode for crops to utilize slightly saline water to obtain fresh water and sufficient slightly saline water at different times, saving time and effort, without the need for separate desalination treatment of slightly saline water outside the plot, and can accurately drip the evaporated and condensed fresh water at the crop seeding place, improving the utilization rate of fresh water by the crops.

[0022] Further, a grooving roller 7 is arranged between the integer roller 1 and the first film spreading roller 2. A set of third shaping discs 701 corresponding to the first shaping discs 101 respectively and annular grooving protrusions 702 arranged between the third shaping discs 701 and corresponding to the ridges 11 are arranged on the grooving roller 7. The end part of the annular grooving protrusion 702 is lower than the upper surface of the ridge 11. The annular grooving protrusion 702, the plug-in seeder 4, and the troughs of the second plastic film 601 are arranged in alignment along the traction direction. The annular grooving protrusion 702 is coaxially arranged with the grooving roller 7. The third shaping discs 701 and the grooving roller 7 shape the ridges 11 in the groove to prevent the ridges 11 from collapsing during the grooving process. The annular grooving protrusion 702 presses a first groove 12 parallel to the traction direction on the ridge 11. The plug-in seeder 4 inserts into the first plastic film 201 to sow seeds in the first groove 12. The trough of the second plastic film 601 is located above the first groove 12. The fresh water condensed on the second plastic film 601 can drip into the first groove 12 along the holes on the first plastic film 201, ensuring that the fresh water can gather at the sowing position of the crop to provide the fresh water required for the growth of the crop.

[0023] The grooving roller 7 is further provided with strip-shaped grooving protrusions 703 arranged parallel to the grooving roller 7 and penetrating through the third shaping discs 701. The end part of the strip-shaped grooving protrusion 703 is lower than the upper surface of the ridge 11. The strip-shaped grooving protrusions 703 are arranged in an array along the grooving roller 7. A perforator 302 matched with the strip-shaped grooving protrusions 703 is arranged between the first film spreading roller 2 and the second film spreading roller 6. The perforator 302 is arranged corresponding to the side of the ridge 11. The grooving roller 7 rotates forward with the traction of the tractor 9, and second grooves 13 perpendicular to the traction direction are pressed at intervals on the upper surface of the ridge 11. The second grooves 13 penetrate through the ridge 11. The perforator 302 penetrates the first plastic film 201 from the side of the ridge 11 to connect the grooves formed by the second grooves 13 and the first plastic film 201. When the crop needs a large amount of water irrigation, the water level in the groove formed by the first plastic film 201 is increased, and the water flows from the second grooves 13 to the first grooves 12, so that the soil at the root of the crop absorbs enough water, and the water level in the groove formed by the first plastic film 201 can be appropriately reduced and still can be irrigated.

[0024] Further, the perforator 302 is arranged on the plastic film shaping roller 3. The end part of the perforator 302 is conical and can perforate the first plastic film 201 at intervals during the rotation of the plastic film shaping roller 3. The perforator 302 is located at the junction of the second shaping disc 301 and the plastic film shaping roller 3. Therefore, the bottom of the holes penetrated by the perforator 302 on the first plastic film 201 is on the side wall of the ridge 11 and lower than the top of the ridge 11, ensuring that the slightly saline water in the groove formed by the first plastic film 201 can fully enter the first plastic film 201 and flow to the first groove 12.

[0025] Further, a plastic film supporting roller 8 is arranged between the first film spreading roller 2 and the plastic film shaping roller 3. The plastic film supporting roller 8 is located between the ridge 11 and the first plastic film 201. The width of the first plastic film 201 is greater than the width of the plot. The plastic film supporting roller 8 is arranged close to the plastic film shaping roller 3. During the process of shaping the first plastic film 201, the plastic film shaping roller 3 enables the first plastic film 201 to be laid along the shape of the ridge 11, narrowing the width of the first plastic film 201. The support of the plastic film supporting roller 8 for the first plastic film 201 can prevent the first plastic film 201 from being disengaged from the ridge 11 prematurely and prevent the first plastic film 201 from damaging the ridge 11 during the movement towards the middle of the plot during the shaping process.

[0026] Further, the insert type seeder 4 is a duckbill type disc seeder. The duckbill type disc seeder is inserted into the soil at intervals during rotation for seeding. When the duckbill type disc seeder is withdrawn, the soil flows towards the seeding place, automatically burying the seeds without manual burial, which can effectively improve the survival rate of the seeds, contribute to seeding and laying the first plastic film 201 and the second plastic film 601 simultaneously, and open holes in the first plastic film 201 during the seeding process, enabling fresh water to drip along the holes to the seeding place of the crops.
