Description

Technical Field

[0001] This utility model relates to the field of seeding technology, specifically a split-type film-laying seeding machine. Background Technology

[0002] A mulching seeder is a combined operation machine that integrates functions such as ditching, fertilizing, sowing, mulching, and covering. It completes multiple agronomic steps in one operation, significantly improving operational efficiency and crop yield. Mulching is an agricultural planting technique that uses perforated plastic film to cover the ground to create a suitable growing environment for crops. This reduces water evaporation and nutrient loss, thereby increasing soil temperature, allowing for earlier sowing, and improving crop yield.

[0003] Referring to Chinese Patent Publication No. CN222302379U, with a publication date of January 7, 2025, a film-laying seeder is disclosed. In this film-laying seeder, during sowing, seeds in the seed box are evenly sprinkled from the sowing port by the rotation of the stirring rod. The sprinkled seeds are then turned and buried in the soil by the soil-adjusting rod. The film roll gradually unfolds as the machine frame moves, and is flattened by support rods and pressing rods, covering the soil above the seeds. The edges are covered by a soil-covering wheel and a round shovel, and perforating rollers punch holes in the film. Finally, the sowing and film-laying work is completed.

[0004] However, during use, the circular shovel assembly and the frame adopt an integrated fixed structure, lacking a separate design, which makes it impossible to quickly adjust the film covering width according to the planting needs of different crops, resulting in poor operational adaptability; the soil-moving operation assembly has functional limitations, and the soil backfilling process after tilling lacks shaping control, making it difficult to form regular ridges that meet agronomic standards, requiring additional manual intervention to adjust the terrain. The overall operation system has functional gaps, so there is still room for further improvement.

[0005] Therefore, we propose a split-type film-laying seeder to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a split-type film-laying seeder to solve the problems mentioned in the background art. In the use of the utility model, the round shovel component and the frame adopt an integrated fixed structure, which lacks a split design. This makes it impossible to quickly adjust the film covering width according to the planting needs of different crops, resulting in poor operational adaptability. The soil-moving component has functional limitations. The soil backfilling process after tilling lacks shaping control, making it difficult to form regular ridges that meet agronomic standards. Additional manual intervention is required to adjust the terrain. The overall operating system has functional gaps, so there is still room for further improvement.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a split-type film-laying seeder, comprising: The frame has a material box on the inner left side, a soil-pulling rod rotatably connected to the middle left side of the inner side of the frame, a rotating rod rotatably connected to the middle right side of the inner side of the frame, and a punching roller rotatably connected to the inner right side of the frame. Also includes: The inner side of the frame is provided with a split mechanism for conveniently covering films of different widths, and the front side of the frame is provided with a servo motor. The inner side of the frame is provided with an adjustment mechanism for facilitating row division, and the inner side of the frame is also provided with a connecting plate.

[0008] Preferably, the front side of the frame is rotatably connected to a movable wheel, and the movable wheel is symmetrical about the vertical central axis of the frame.

[0009] Preferably, the front side of the frame is threaded with a first threaded rod, and the first threaded rod is rotatably connected to the clamping plate. The first threaded rod is symmetrical about the vertical central axis of the frame, and a film cylinder is tightly attached to the inner side of the clamping plate.

[0010] Preferably, the split mechanism is composed of a servo motor, a bidirectional threaded rod, a vertical plate, a bucket, and a first limiting rod. The output shaft of the servo motor is fixedly connected to the bidirectional threaded rod, the bidirectional threaded rod is rotatably connected to the frame, and the bidirectional threaded rod is threadedly connected to the vertical plate.

[0011] Preferably, the vertical plate is fixedly connected to the bucket, and both the vertical plate and the bucket are symmetrical about the vertical central axis of the frame. The vertical plate is slidably connected to the first limiting rod, and the first limiting rod is fixedly connected to the frame.

[0012] Preferably, the adjusting mechanism is composed of a second threaded rod, a leveling plate, and a second limiting rod. The second threaded rod is threadedly connected to the connecting plate and rotatably connected to the leveling plate. The leveling plate is fixedly connected to the second limiting rod, and the second limiting rod is slidably connected to the connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the servo motor is started, the bidirectional threaded rod rotates, which drives the vertical plate to slide along the first limit rod, so that the two buckets move closer or further away at the same time, quickly adjusting the film covering width to adapt to the planting needs of different crops and improve the operability. When the second threaded rod is rotated, the leveling plate moves up and down along the second limit rod, which precisely controls the height of the backfill soil, forming regular ridges, reducing manual intervention and improving agronomic standards. 1. The system is equipped with a soil-moving rod, a rotating rod, and a perforating roller. The soil-moving rod turns the soil over to cover the seeds, and the perforating roller perforates the film to ensure that the seeds can be aerated, forming a complete operation process.

[0014] 2. It is equipped with movable wheels, a first threaded rod and a clamping plate. The movable wheels support the movement of the frame, and rotating the first threaded rod pushes the clamping plate to clamp the film cylinder, which facilitates film replacement and ensures film laying stability.

[0015] 3. Equipped with a servo motor, a bidirectional threaded rod, and a bucket, starting the servo motor causes the bidirectional threaded rod to rotate, driving the vertical plate to slide along the first limit rod, so that the buckets on both sides move closer or further apart synchronously, quickly adjusting the film coverage width to adapt to the planting needs of different crops and improve operational adaptability.

[0016] 4. Equipped with a second threaded rod, a leveling plate, and a second limiting rod, rotating the second threaded rod causes the leveling plate to rise and fall along the second limiting rod, precisely controlling the height of the backfill soil, forming regular ridges, reducing manual intervention, and improving agronomic standards.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5As shown, this utility model provides a technical solution: a split-type film-laying seeder, including: a frame 1, a material box 2, a soil-pulling rod 3, a rotating rod 4, a perforating roller 5, a moving wheel 6, a first threaded rod 7, a clamping plate 8, a film cylinder 9, a servo motor 10, a bidirectional threaded rod 11, a vertical plate 12, a bucket 13, a first limiting rod 14, a connecting plate 15, a second threaded rod 16, a leveling plate 17, and a second limiting rod 18.

[0021] In the existing utility model, the circular shovel assembly and the frame 1 adopt an integrated fixed structure, lacking a separate design, which makes it impossible to quickly adjust the film covering width according to the planting needs of different crops, resulting in poor operational adaptability; the soil-moving operation assembly has functional limitations, and the soil backfilling process after tilling lacks shaping control, making it difficult to form regular ridges that meet agronomic standards, requiring additional manual intervention to adjust the terrain. The overall operation system has functional gaps, so there is still room for further improvement.

[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, during the film-laying and sowing operation, the frame (1) moves on the ground via the moving wheels (6). A material box (2) is set inside the frame (1), and seeds are placed inside the material box (2). The seeds in the material box (2) fall onto the soil surface. During the movement of the frame (1), the soil-pulling rod (3) rotates. The rotating soil-pulling rod (3) flips the soil to cover the seeds. The rotating rod (4) assists in conveying the film through the film-coating cylinder (9). The perforating roller (5) punches holes in the film to ensure that the seeds can grow and breathe, thus forming a complete operation process.

[0023] like Figure 2 , Figure 3 and Figure 5 As shown, when the film coverage width needs to be adjusted, the servo motor (10) is started, and its output shaft drives the bidirectional threaded rod (11) to rotate. Since the threads at both ends of the bidirectional threaded rod (11) are opposite and are threadedly connected to the vertical plates (12) on both sides, the vertical plates (12) will slide inward or outward along the first limiting rod (14). The vertical plates (12) drive the buckets (13) to move synchronously, adjusting the distance between the two buckets (13), thereby changing the width of the film coverage to adapt to the planting needs of different crops. The first limiting rod (14) limits the movement of the vertical plates (12), ensuring the smoothness and accuracy of the movement. Since the buckets (13) and the frame (1) are designed separately, they are easy to adjust.

[0024] like Figure 1 , Figure 2 and Figure 5As shown, when it is necessary to form regular ridges, the second threaded rod (16) is rotated. Since the second threaded rod (16) is threadedly connected to the connecting plate (15), the leveling plate (17) will move up and down along the second limiting rod (18). By adjusting the height of the leveling plate (17), the height and slope of the backfill soil are controlled, thereby forming regular ridges that meet agronomic standards. The second limiting rod (18) ensures the stability of the leveling plate (17) during its rise and fall, ensuring the consistency of the ridge formation.

[0025] It should be noted that when the film tube (9) needs to be replaced, the first threaded rod (7) is rotated, and the first threaded rod (7) pushes the clamping plate (8) to move outward, releasing the clamping of the film tube (9). After removing the old film tube (9) and installing the new film tube (9), the first threaded rod (7) is rotated in the opposite direction to make the clamping plate (8) clamp the film tube (9) to ensure that the film tube (9) rotates stably during the film laying process.

[0026] The contents not described in detail in this specification are existing technologies known to those skilled in the art. All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
