Description

Technical Field

[0001] This utility model relates to a multi-port soil discharge and stable film-laying seeding device, belonging to the field of film-laying seeding technology. Background Technology

[0002] In arid and semi-arid regions, rainfall is scarce and unevenly distributed, leading to high soil moisture evaporation. Traditional sowing methods often result in seed dehydration, low germination rates, and inhibited crop growth. Furthermore, in some areas, the soil is poor, salinized, or severely desertified, making direct sowing susceptible to wind erosion and soil compaction, further reducing crop yields. However, covering the ground with plastic film (mostly polyethylene or biodegradable materials) can reduce soil moisture evaporation (increasing water retention by 30%-50%) and simultaneously block heat exchange between the soil and atmosphere, raising the average soil temperature by 2-4°C, creating a suitable environment for seed germination.

[0003] By integrating mulching and sowing, mulching and sowing processes can be completed simultaneously, improving agricultural efficiency. For example, patent application CN202421420123.6 discloses a multi-functional mulching and sowing machine, including a tracked tractor head. A fixed frame is fixedly mounted at the rear of the tracked tractor head, and two support wheels are symmetrically mounted on both sides of the rear of the fixed frame. A traction frame, driven by a hydraulic cylinder, is hinged to the middle of the fixed frame, allowing it to swing up and down at its rear end. This device can achieve simultaneous mulching and double-row sowing, improving agricultural efficiency. However, if only soil is covered on both sides of the mulch film, it is difficult to withstand severe wind and rain, and agricultural efficiency needs further improvement. Utility Model Content

[0004] This invention provides a multi-port soil-draining and stable film-laying sowing device, which can achieve multi-row highly stable film-laying sowing, reduce film damage, significantly improve agricultural efficiency, and effectively resist severe wind and rain weather.

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

[0006] A multi-port soil-discharging and stabilizing film-laying seeding device includes a mounting bracket, a soil leveling assembly, a furrowing and fertilizing leg, a depth-limiting ground wheel, a fertilizer box, a soil conveying device, a soil-pressing and shaping device, a film hanging frame, a drip irrigation assembly, and a seed metering assembly.

[0007] The leveling assembly, trenching and fertilizing leg, soil smoothing and shaping device, mulch film hanger, drip irrigation assembly and seed metering assembly are installed on the mounting bracket from front to back;

[0008] The number of trenching and fertilizing legs and soil tamping and shaping devices are set in pairs of three or more, with the number of trenching and fertilizing legs and soil tamping and shaping devices being equal and corresponding one-to-one;

[0009] The soil-forming device includes a soil-forming rod and a soil-forming shovel; the soil-forming shovel is inclined and its top is hinged to the mounting bracket, and the bottom of the soil-forming shovel has a bend pointing towards the mulch film hanger; the top of the soil-forming rod is height-adjustably connected to the mounting bracket, and the bottom of the soil-forming rod is hinged to the soil-forming shovel above the bend. By adjusting the connection height of the soil-forming rod, the angle and height of the soil-forming shovel can be adjusted.

[0010] The fertilizer box is installed on the mounting bracket above the trenching fertilization leg. The bottom of the fertilizer box has more than three fertilizer outlets. The number of fertilizer outlets is equal to the number of trenching fertilization legs and corresponds one-to-one. Each fertilizer outlet is connected to the corresponding trenching fertilization leg through a pipeline.

[0011] The soil conveying device includes a soil conveying pipe box, which is installed on a mounting bracket. The soil conveying pipe box is equipped with a soil inlet and a soil outlet. The soil inlet is located between the trenching and fertilizing leg and the soil tamping and shaping device, and the soil outlet is located between the mulch film hanger and the seed metering device assembly. The number of soil outlets is equal to the number of soil tamping and shaping devices, and they correspond one-to-one. A chain conveyor or screw conveyor is installed in the soil conveying pipe box between the soil inlet and the soil outlet to transport the soil entering through the soil inlet to the soil outlet.

[0012] There are two depth-limiting wheels, which are arranged opposite each other on both sides of the front end of the mounting bracket.

[0013] The number of trenching fertilization legs in this application is three or more arranged side by side, that is, each trenching fertilization leg is arranged in parallel in the same row. Other similar expressions have similar meanings.

[0014] The direction from back to front on the mounting bracket of this application is consistent with the driving direction of the multi-port soil discharge stabilizing film laying and sowing device during use.

[0015] The aforementioned mounting bracket is equipped with a suspension device at its front end, and the multi-port soil discharge stabilizing film laying and seeding device is connected to a traction device (such as a tractor) through the suspension device.

[0016] During operation, the tractor drives the multi-port soil-discharging, stabilizing, film-laying, and seeding device forward. The soil leveling assembly improves land flatness, reduces the risk of film damage, and enhances seeding stability. The ditching and fertilizing leg opens furrows while moving, and fertilizer from the fertilizer box falls into the furrows from the corresponding outlets. The soil-pressing and shaping device then presses the soil to fill the furrows and level the ground before laying the film. The soil-pressing and shaping device not only helps to press the soil to fill the furrows and retain fertilizer but also creates conditions for laying the film, reducing film damage, improving film stability, and facilitating seeding. The soil conveying device's inlet is located between the ditching and fertilizing leg and the soil-pressing and shaping device, meaning the soil is loaded before the pressing. The soil enters the conveying device, is transported by a chain conveyor or screw conveyor, and is discharged from the outlet, pressing onto the film. Simultaneously, a drip irrigation assembly is integrated, allowing the drip irrigation pipes to be laid during film laying and seeding. Finally, seeding is completed via the seed metering assembly.

[0017] The finger-clamp precision seeders in the above-mentioned furrowing and fertilizing leg, fertilizer outlet, soil compactor, soil discharge outlet, and seed metering assembly are all of equal quantity and correspond one-to-one. After the furrowing and fertilizing leg completes the furrowing, the fertilizer from the corresponding fertilizer outlet falls into the corresponding furrow, and then the corresponding soil compactor completes the soil compaction and filling of the furrow. Next, the film is laid, and then the corresponding soil discharge outlet discharges and presses the film down. Finally, the corresponding finger-clamp precision seeder completes the sowing.

[0018] When in use, the plastic film is rolled up and hung on the plastic film hanger, which can cover the entire sowing width. When multiple rows of sowing are required, the width of the plastic film can be increased to achieve multiple rows with one film. Multiple soil discharge ports are also set up to effectively ensure the stability of the plastic film and sowing.

[0019] This application effectively reduces membrane damage and achieves highly stable membrane laying by using a leveling assembly, a soil-pressing and shaping device, and a multi-row soil inlet design, which can effectively resist severe wind and rain weather.

[0020] When the soil conveying pipe box contains a chain conveyor, it includes a driving sprocket, a driven sprocket, and a chain that meshes with the driving and driven sprockets. The chain has soil-collecting blades distributed along its outer periphery. When it is a screw conveyor, it includes a screw shaft and screw blades disposed around the screw shaft.

[0021] This application does not improve the drive structure and method of chain conveyor and screw conveyor; refer to existing technology or product manuals for details, and therefore will not elaborate further.

[0022] For easy adjustment, the trenching and fertilizing legs are height-adjustably connected to the mounting bracket; the leveling assembly includes a leveling connecting rod and a scraper, with the scraper connected to the bottom of the leveling connecting rod, and the top of the leveling connecting rod height-adjustably connected to the mounting bracket. This allows the height of the trenching and fertilizing legs and the leveling assembly to be adjusted as needed.

[0023] The height-adjustable structure of this application can be achieved by setting connecting holes or connecting pipes on the mounting bracket, installing the tops of leveling connecting rods, trenching and fertilizing legs, etc., inside the connecting holes or connecting pipes, and fixing them with bolts and nuts. The height installed inside the connecting holes or connecting pipes can be adjusted as needed, thereby achieving height adjustment.

[0024] The aforementioned seed metering assembly includes a finger-clamp precision seeder and a seed box; the finger-clamp precision seeder is rotatably mounted on a mounting bracket, and the number of finger-clamp precision seeders is three or more arranged side by side; the number of seed boxes is equal to the number of finger-clamp precision seeders and corresponds one-to-one, the seed box is mounted on the mounting bracket and located above the corresponding finger-clamp precision seeder, and the bottom of the seed box is connected to the seed inlet on the side of the corresponding finger-clamp precision seeder through a seed drop tube.

[0025] The finger-clamp precision seeding device of this application can adopt the structure in application number 201510199955.9. This application does not improve the structure of the finger-clamp precision seeding device itself, so it will not be described in detail here.

[0026] The number of the aforementioned finger-clamp precision seeders is equal to the number of furrow fertilization legs, and they correspond one-to-one. The corresponding furrow fertilization legs and finger-clamp precision seeders are located in the same column.

[0027] The direction of the columns in this application is perpendicular to the direction of the rows, and the direction of the columns and rows is consistent with the direction of travel of the device.

[0028] In one specific implementation scheme, the number of trenching and fertilizing legs and the soil-forming device are three each (that is, the trenching and fertilizing legs include trenching and fertilizing legs on both sides and the middle trenching and fertilizing leg, and the soil-forming device includes soil-forming devices on both sides and the middle soil-forming device); the soil conveying pipe box is located between the trenching and fertilizing legs and the seed metering device assembly; the soil conveying pipe box includes a left pipe box, a middle drop pipe and a right pipe box; the middle drop pipe is located between the left pipe box and the right pipe box, and the middle drop pipe is inverted V-shape. The top two ends of the pipe connect to the side walls of the left and right pipe boxes, forming an M shape. The bottom of the middle pipe is the central soil discharge port. The left and right pipe boxes are located directly behind the fertilization legs on both sides. Both the left and right pipe boxes are inverted V-shaped, with soil inlets at the front bottom of the left and right pipe boxes and side soil discharge ports at the rear outer bottom of the left and right pipe boxes. A chain conveyor or screw conveyor is installed inside the left and right pipe boxes between the soil inlets and the side soil discharge ports. The chain conveyor or screw conveyor transports part of the soil entering from the soil inlets to the connection between the left and right pipe boxes and the middle pipe. Under the action of gravity, the soil falls down the middle pipe and is finally discharged from the soil discharge port at the bottom of the middle pipe, thus pressing the soil in the film. The rest is transported to the side soil discharge port for pressing the soil at the edge of the film. At this point, the film laying is completed. Finally, the seed metering device completes the sowing, using a one-film-three-row sowing method. The applicable film width is 1.3 meters to 1.6 meters.

[0029] The outer sides of the aforementioned left and right pipe boxes refer to the sides that are opposite to each other.

[0030] The two outer trenching fertilization legs mentioned above refer to the trenching fertilization legs located on both sides. When there are three trenching fertilization legs, there is one in the middle and one on each side (relative to the middle).

[0031] To facilitate soil loading, a slanted shovel is installed at the bottom of the loading port. This allows the slanted shovel to easily scoop soil onto the soil-collecting blades or auger blades, ensuring the amount of soil collected.

[0032] For ease of maintenance, both the left and right pipe boxes are equipped with inspection ports on their outer sides, each with a movable inspection door. These doors allow for inspection or maintenance of the conveying device.

[0033] As another specific implementation scheme, there are four trenching and fertilizing legs and four soil-forming devices. The soil conveying pipe box is located between the trenching and fertilizing legs and the seed metering assembly. The soil conveying pipe box includes a left pipe box, a middle drop pipe, and a right pipe box. The middle drop pipe is located between the left and right pipe boxes and includes a first inclined pipe, a second inclined pipe, and a middle connecting pipe. Both the first and second inclined pipes are inclined, with their tops connected to the side walls of the left and right pipe boxes respectively, and their bottoms pointing towards the ground as middle soil discharge ports. The two ends of the middle connecting pipe are connected to the outer walls of the first and second inclined pipes respectively. The left and right pipe boxes are located directly behind the trenching and fertilizing legs on both sides. Both the left and right pipe boxes are inverted V-shaped, with soil inlets at the front bottom of the left and right pipe boxes, and side soil discharge ports at the rear bottom of the left and right pipe boxes. Chain conveying devices or screw conveying devices are installed in the left and right pipe boxes between the soil inlets and the side soil discharge ports. This scheme has four soil discharge ports. A chain conveyor or screw conveyor transports a portion of the soil entering from the top inlet to the connection points between the left and right pipe boxes and the first and second inclined pipes. Under gravity, the soil falls down the first and second inclined pipes and is finally discharged from their outlets, providing soil coverage for two rows within the film. The remaining soil is transported to the side outlets for edge coverage. This completes the film laying process. Finally, the seed metering device completes the sowing, employing a four-row sowing method with one film.

[0034] This application may choose to install either a chain conveyor or a screw conveyor.

[0035] For ease of use, the fertilizer box features a fertilizer cover on top, with sliding shafts at the rear ends of both sides of the top. Both sides of the fertilizer cover have downward-folding flanges, and each flange has an oppositely positioned elongated sliding hole. These holes slide smoothly onto the two sliding shafts on the top of the fertilizer box. The rear end of the fertilizer cover is not flanged. To open the fertilizer cover, the front end is folded upwards and outwards. The cover rotates along the sliding shafts. When the cover reaches a vertical position, it slides downwards under gravity and manual control until the sliding shafts engage with the sliding holes, preventing further downward movement. This ingenious and reasonable design eliminates the need to remove the fertilizer cover when opening it, saving time and effort, simplifying operation, and preventing the cover from being lost.

[0036] Any technologies not mentioned in this utility model are based on existing technologies.

[0037] This utility model of a multi-port soil-draining and stabilizing film-laying and sowing device reduces the risk of film damage, improves sowing stability, and enables multi-row highly stable film-laying and sowing. It can simultaneously complete steps such as leveling, ditching, fertilizing, film laying, drip irrigation pipe laying, and sowing, significantly improving agricultural efficiency and effectively resisting severe wind and rain weather; it is also easy to adjust and has good adaptability.

The seeding box is omitted in the drawings.

[0048] Example 1

[0049] like Figure 1-3 As shown, a multi-port soil-draining and stabilizing film-laying seeding device includes a mounting bracket, a soil leveling assembly, a furrowing and fertilizing leg, a depth-limiting ground wheel, a fertilizer box, a soil conveying device, a soil-pressing and shaping device, a film hanging frame, a drip irrigation assembly, and a seed metering assembly.

[0050] The leveling assembly, trenching and fertilizing leg, soil smoothing and shaping device, mulch film hanger, drip irrigation assembly and seed metering assembly are installed on the mounting bracket from front to back;

[0051] The number of trenching and fertilizing legs and soil tamping and shaping devices are set in pairs of three or more, with the number of trenching and fertilizing legs and soil tamping and shaping devices being equal and corresponding one-to-one;

[0052] like Figure 4 As shown, the soil-forming device includes a soil-forming rod and a soil-forming shovel; the soil-forming shovel is inclined and its top is hinged to the mounting bracket, and the bottom of the soil-forming shovel has a bend pointing towards the mulch film hanger; the top of the soil-forming rod is height-adjustably connected to the mounting bracket, and the bottom of the soil-forming rod is hinged to the soil-forming shovel above the bend. By adjusting the connection height of the soil-forming rod, the angle and height of the soil-forming shovel can be adjusted.

[0053] The fertilizer box is installed on the mounting bracket above the trenching fertilization leg. The bottom of the fertilizer box has more than three fertilizer outlets. The number of fertilizer outlets is equal to the number of trenching fertilization legs and corresponds one-to-one. Each fertilizer outlet is connected to the corresponding trenching fertilization leg through a pipeline.

[0054] The soil conveying device includes a soil conveying pipe box, which is installed on a mounting bracket. The soil conveying pipe box is equipped with a soil inlet and a soil outlet. The soil inlet is located between the trenching and fertilizing leg and the soil compactor, and the soil outlet is located between the mulch film hanger and the seed metering assembly. The number of soil outlets is equal to the number of soil compactors and corresponds one-to-one. A chain conveyor or a screw conveyor is installed inside the soil conveying pipe box between the soil inlet and the soil outlet.

[0055] There are two depth-limiting wheels, which are arranged opposite each other on both sides of the front end of the mounting bracket.

[0056] The aforementioned mounting bracket is equipped with a suspension device at its front end, and the multi-port soil discharge stabilizing film laying and seeding device is connected to a traction device (such as a tractor) through the suspension device.

[0057] During operation, the tractor drives the multi-port soil-discharging, stabilizing, film-laying, and seeding device forward. The soil leveling assembly improves land flatness, reduces the risk of film damage, and enhances seeding stability. The ditching and fertilizing leg opens furrows while moving, and fertilizer from the fertilizer box falls into the furrows from the corresponding outlets. The soil-pressing and shaping device then presses the soil to fill the furrows and level the ground before laying the film. The soil-pressing and shaping device not only helps to press the soil to fill the furrows and retain fertilizer but also creates conditions for laying the film, reducing film damage, improving film stability, and facilitating seeding. The soil conveying device's inlet is located between the ditching and fertilizing leg and the soil-pressing and shaping device, meaning the soil is loaded before the pressing. The soil enters the conveying device, is transported by a chain conveyor or screw conveyor, and is discharged from the outlet, pressing onto the film. Simultaneously, a drip irrigation assembly is integrated, allowing the drip irrigation pipes to be laid during film laying and seeding. Finally, seeding is completed via the seed metering assembly.

[0058] The finger-clamp precision seeders in the above-mentioned furrowing and fertilizing leg, fertilizer outlet, soil compactor, soil discharge outlet, and seed metering assembly are all of equal quantity and correspond one-to-one. After the furrowing and fertilizing leg completes the furrowing, the fertilizer from the corresponding fertilizer outlet falls into the corresponding furrow, and then the corresponding soil compactor completes the soil compaction and filling of the furrow. Next, the film is laid, and then the corresponding soil discharge outlet discharges and presses the film down. Finally, the corresponding finger-clamp precision seeder completes the sowing.

[0059] When in use, the plastic film is rolled up and hung on the plastic film hanger, which can cover the entire sowing width. When multiple rows of sowing are required, the width of the plastic film can be increased to achieve multiple rows with one film. Multiple soil discharge ports are also set up to effectively ensure the stability of the plastic film and sowing.

[0060] This application effectively reduces membrane damage and achieves highly stable membrane laying by using a leveling assembly, a soil-pressing and shaping device, and a multi-row soil inlet design, which can effectively resist severe wind and rain weather.

[0061] When the soil conveying pipe box contains a chain conveyor, it includes a driving sprocket, a driven sprocket, and a chain that meshes with the driving and driven sprockets, with soil-collecting blades on the chain. When it is a screw conveyor, it includes a screw shaft and screw blades disposed around the screw shaft.

A chain conveyor or screw conveyor transports a portion of the soil entering from the top inlet to the connection points between the left and right side pipe boxes and the central drop pipe. Under gravity, the soil falls down the central drop pipe and is finally discharged from the soil outlet at the bottom of the central drop pipe, thus pressing the soil within the film. The remaining soil is transported to the side outlets for soil pressing along the edges of the film. This completes the film laying process. Finally, the seed metering device completes the sowing, using a three-row sowing method with one film. In this example, the row spacing is 350mm, but a 400mm row spacing can also be designed.

[0068] Example 5

[0069] Based on Example 4, the following improvements were made: To facilitate soil loading, a slanted shovel is provided at the bottom of the loading port. This allows the slanted shovel to easily scoop soil onto the soil-collecting blades or auger blades, ensuring sufficient soil volume.

This scheme has four soil discharge outlets. A chain conveyor or screw conveyor will transport a portion of the soil entering from the upper outlet to the connection points between the left and right pipe boxes and the first and second inclined pipes. Under gravity, the soil will fall down the first and second inclined pipes and finally be discharged from their outlets, providing soil coverage for two rows within the film. The remaining soil will be transported to the side outlets for edge coverage. This completes the film laying process. Finally, the seed metering device will complete the sowing, employing a four-row sowing method with one film.

For ease of maintenance, inspection ports are provided on the outer sides of both the left and right pipe boxes, each equipped with a movable inspection door. The inspection doors can be opened to inspect or maintain the conveying device.

[0074] Example 8

[0075] Based on embodiments 4-6, the following improvements were made: For ease of use, the fertilizer box has a fertilizer cover on top, and sliding shafts are located at the rear ends of both sides of the fertilizer cover. The fertilizer cover has downward-folding flanges on both sides, and elongated sliding holes are provided on the flanges on both sides of the fertilizer cover. These elongated sliding holes on the flanges of the fertilizer cover slide and engage with the two sliding shafts on the top of the fertilizer box. The rear end of the fertilizer cover does not have flanges. When the fertilizer cover needs to be opened, the front end of the fertilizer cover is folded upwards and outwards. The fertilizer cover rotates along the sliding shafts. When the fertilizer cover rotates to a vertical position, it slides downwards under the control of gravity and the operator's hand until the sliding shaft engages with the end of the sliding hole, preventing the fertilizer cover from sliding further downwards. The aforementioned structural design is ingenious and reasonable. When the fertilizer cover needs to be opened, it is not necessary to remove it, saving time and effort, facilitating operation, and preventing the fertilizer cover from being lost.
