[0002] Existing pneumatic seeders have non-adjustable seats and armrests. This fixed position of the seat and armrests affects the efficiency of different operators. Furthermore, the rearward-facing handles cause discomfort due to the close proximity of the armrests to the seat. While adjusting the seat backward alleviates this discomfort, it increases the distance between the operator and the seeder, significantly impacting accurate control and observation of the seeding process. Therefore, developing a novel pneumatic seeder is a pressing issue for those skilled in the art.

[0051] To better understand the purpose, structure, and function of this utility model, a pneumatic seeder will be described in further detail below with reference to the accompanying drawings.

[0052] Example 1

[0053] like Figure 1-5 As shown, the pneumatic seeder of this invention includes a frame 1, a first adjustment mechanism 2, a second adjustment mechanism 3, and a seat 8. The frame 1 cooperates with the first adjustment mechanism 2; the frame 1 also cooperates with the second adjustment mechanism 3. The first adjustment mechanism 2 includes a first handrail 21 and a second handrail 22; the second adjustment mechanism 3 cooperates with the seat 8; the first handrail 21 is positioned away from the seat 8. By incorporating the first adjustment mechanism 2 and the second adjustment mechanism 3 into the pneumatic seeder, the operator can adjust the positions of the handrails and the seat 8 using these mechanisms to accommodate different operator needs. The handrails on the first adjustment mechanism 2 are positioned away from the seat 8, preventing the operator from being too far from the seeder due to the handrails, thus allowing for better control of the seeder and better observation of the sowing process.

[0054] The first adjustment mechanism 2 in this embodiment includes a first adjustment frame 23 and a first locking component 24; the first adjustment frame 23 and the first locking component 24 cooperate with each other. By including the first adjustment frame 23 and the first locking component 24, the first adjustment frame 23 in the first adjustment mechanism 2 can be adjusted to achieve height adjustment, and the first locking component 24 in the first adjustment mechanism 2 can fix and loosen the position of the first adjustment frame 23. Through the cooperation of the first adjustment frame 23 and the first locking component 24, the first adjustment frame 23 and the first locking component 24 in the first adjustment mechanism 2 can cooperate to achieve height adjustment and fixation of the first handrail 21 and the second handrail 22 on the first adjustment frame 23.

[0055] The first adjustment frame 23 of this embodiment includes a vertical portion 2301 and a curved portion 2302; the first armrest 21 is connected to the curved portion 2302; the second armrest 22 is connected to the vertical portion 2301; and the first locking assembly 24 is fixedly connected to the frame 1. By including the vertical portion 2301 and the curved portion 2302, the first adjustment frame 23 can be divided into a vertically upward portion and a curved portion away from the seat 8. The connection between the first armrest 21 and the curved portion 2302 places the part of the first armrest 21 away from the seat 8, thereby allowing the operator to more comfortably hold the armrest on the seat 8. Furthermore, because the first armrest 21 is positioned forward, the position of the seat 8 can also be further forward than the existing seat 8 position, making it easier for the operator to observe the equipment and work area.

[0056] The first locking assembly 24 in this embodiment includes a first sleeve component 241 and a first locking component 242. The first sleeve component 241 is provided with a first locking hole 243. The first locking component 242 cooperates with the first adjusting frame 23 through the first locking hole 243. By including the first sleeve component 241 and the first locking component 242, the first sleeve component 241 in the first locking assembly 24 can cooperate with the first adjusting frame 23, allowing the first adjusting frame 23 to slide within the first sleeve component 241, thereby changing the height of the first handrail 21 and the second handrail 22. Then, through the locking function of the first locking component 242, it locks the first adjusting frame 23 in the first sleeve. The first sleeve component 241 is provided with a first locking hole 243. This allows the first locking hole 243 to engage with the first locking component 242, enabling the first locking component 242 to perform a locking action through the first locking hole 243. The first locking component 242 engages with the first adjusting frame 23 through the first locking hole 243, allowing the first locking component 242 to pass through the first locking hole 243 and press against the first adjusting frame 23 to control the first adjusting frame 23. Preferably, this application uses a bolt as the first locking component 242 to lock the first adjusting frame 23.

[0057] The second adjustment mechanism 3 in this embodiment includes a second adjustment frame 31, a third adjustment frame 32, a second locking component 33, and a third locking component 34; the second adjustment frame 31 cooperates with the second locking component 33; and the third adjustment frame 32 cooperates with the third locking component 34. The second adjustment mechanism 3, comprising a second adjustment frame 31, a third adjustment frame 32, a second locking assembly 33, and a third locking assembly 34, enables the second adjustment mechanism 3 to control the height and lateral distance of the seat 8 via the second adjustment frame 31, the third adjustment frame 32, the second locking assembly 33, and the third locking assembly 34. The second adjustment frame 31, in conjunction with the second locking assembly 33, allows the second adjustment frame 31 to adjust and lock the height of the seat 8 mounted on it via the second locking assembly 33. The third adjustment frame 32, in conjunction with the third locking assembly 34, allows the lateral translation distance of the third adjustment frame 32—that is, the distance by which the third adjustment frame 32 moves the seat 8 laterally—to be adjusted and locked via the cooperation of the third adjustment frame 32 and the third locking assembly 34.

[0058] In this embodiment, the second adjustment frame 31 is connected to the seat 8; the second locking assembly 33 includes a second sleeve component 331 and a second locking component 332; the second sleeve component 331 is connected to the third adjustment frame 32. The connection between the second adjustment frame 31 and the seat 8 allows the movement of the seat 8 to be synchronized by the movement of the second adjustment frame 31; the second locking assembly 33, including the second sleeve component 331 and the second locking component 332, allows the second sleeve component 331 to be slidably connected to the second adjustment frame 31, enabling the second adjustment frame 31 to achieve height adjustment and locking through the cooperation of the second sleeve component 331 and the second locking component 332; the connection between the second sleeve component 331 and the third adjustment frame 32 allows the second sleeve component 331 to achieve lateral distance adjustment and locking through the third adjustment frame 32, that is, to drive the second adjustment frame 31 and the seat 8 connected to the second adjustment frame 31 to perform lateral distance adjustment and locking.

[0059] In this embodiment, the second sleeve component 331 is provided with a second locking hole 333; the second locking component 332 cooperates with the second adjusting frame 31 through the second locking hole 333. The second locking hole 333 on the second sleeve component 331 allows it to cooperate with the second locking component 332, thereby achieving adjustment and locking of the second adjusting frame 31. The second locking component 332, through the second locking hole 333, can pass through the second locking hole 333 and apply pressure to the second adjusting frame 31, thereby locking the second adjusting frame 31. The second locking component 332 in this application is preferably a bolt component.

[0060] The third locking assembly 34 in this embodiment includes a third sleeve component 341 and a third locking component 342. The third sleeve component 341 is fixedly connected to the frame 1. The third sleeve component 341 is provided with a third locking hole 343. The third locking component 342 cooperates with the third adjusting frame 32 through the third locking hole 343. By including the third sleeve component 341 and the third locking component 342, the third locking assembly 34 can adjust and lock the lateral distance of the third adjusting frame 32 through the cooperation of the third sleeve component 341 and the third locking component 342. By fixing the third sleeve component 341 to the frame 1, the third sleeve component 341 can be fixed to the frame 1, thereby allowing the third adjusting frame 32 to move relative to the third sleeve component 341, thus realizing the adjustment and locking of the third adjusting frame 32. The frame 1 moves a distance; the third sleeve component 341 is provided with a third locking hole 343, so that when the third sleeve component 341 cooperates with the third adjustment frame 32, it can lock the third adjustment frame 32 through the third locking hole 343; the third locking component 342 cooperates with the third adjustment frame 32 through the third locking hole 343, so that the third locking component 342 can pass through the third locking hole 343 and press the surface of the third adjustment frame 32, thereby locking the third adjustment frame 32.

[0061] This embodiment also includes a front wheel mechanism 6, a power mechanism 4, and a suction mechanism 5; the power mechanism 4 is mounted above the front of the front wheel mechanism 6 via a frame 1; the suction mechanism 5 is mounted above the rear of the front wheel mechanism 6 via a frame 1. This application further includes a front wheel mechanism 6, a power mechanism 4, and a suction mechanism 5. The power mechanism 4 is mounted above the front of the front wheel mechanism 6 via a frame 1, and the suction mechanism 5 is mounted above the rear of the front wheel mechanism 6 via a frame 1. This arrangement, with the power mechanism 4 and suction mechanism 5 positioned at the front and rear of the front wheel mechanism 6 respectively, and the heavier components primarily located above the front wheel mechanism 6, makes steering easier and more convenient for the operator, thereby reducing the operator's workload.

[0062] In this embodiment, the frame 1 has an angled portion 7 at the front of the front wheel mechanism 6. By providing the angled portion 7 at the front of the front wheel mechanism 6 on the frame 1, the air-suction seeder can avoid obstacles during operation and facilitates unloading and transfer.

[0063] The working principle and process of this embodiment:

[0064] I. Overview of Working Principle

[0065] This air-suction seeder achieves adaptive adjustment of the "human-machine working environment" through the coordinated operation of modular adjustment mechanisms (first adjustment mechanism 2, second adjustment mechanism 3) and core functional modules (power mechanism 4, air-suction mechanism 5, front wheel mechanism 6), balancing operational comfort, sowing accuracy, and work efficiency. Its core principle can be summarized in the following three points:

[0066] 1. Ergonomic adjustment: The first adjustment mechanism 2 (armrest height) and the second adjustment mechanism 3 (seat 8 height / lateral distance adjustment) are used to adapt to operators of different body types and operating habits, ensuring that the operator is in the best operating position (such as the armrest is moved away from the seat 8 to avoid excessive forward tilting, and the seat 8 is moved laterally to expand the field of vision).

[0067] 2. Modular Functional Layout: The power unit 4 (providing driving and air suction power), air suction unit 5 (seed suction / seed throwing core), and front wheel unit 6 (steering and support) are distributed on the frame 1 according to the principle of "front heavy and rear light". The center of gravity is close to the front wheel to reduce steering resistance. At the same time, the oblique part 7 of the frame 1 optimizes passability and storage convenience.

[0068] 3. Air suction sowing mechanism: The negative pressure airflow is used to adsorb seeds (air suction mechanism 5). By precisely controlling the negative pressure and the timing of seed release, single-seed precision sowing is achieved, reducing seed waste and improving seedling uniformity.

[0069] II. Detailed Work Process

[0070] The working process of this seeder can be divided into the pre-start adjustment stage, the driving and steering stage, the sowing operation stage, and the storage / transfer stage, as detailed below:

[0071] 1. Pre-start adjustment phase (adapting to operators and operational needs)

[0072] Operators need to set the initial position using the first adjustment mechanism 2 and the second adjustment mechanism 3, based on their own height, arm length, and the conditions of the working field.

[0073] First adjustment mechanism 2 (armrest position adjustment):

[0074] Objective: To adjust the height of the first handrail 21 and the second handrail 22 so that the operator's arms are placed naturally without excessive forward leaning.

[0075] step:

[0076] ① Loosen the first locking component 242 (such as a bolt) of the first locking assembly 24 to release the lock on the first adjusting bracket 23;

[0077] ② Slide the first adjusting bracket 23 up and down along the first sleeve component 241 (vertical sleeve) to adjust the height of the bent part 2302 (handrail installation section) to the target position;

[0078] ③ The second handrail 22 (connected to the vertical part 2301) rises and falls synchronously with the first adjusting frame 23, maintaining consistency with the operating logic of the main handrail.

[0079] Second adjustment mechanism 3 (seat 8 position adjustment):

[0080] Objective: To adjust the height of seat 8 (to accommodate leg length) and the lateral distance (to accommodate arm span and field of vision) to ensure that the operator is comfortable in the seat position and can clearly observe the sowing area.

[0081] step:

[0082] ① Loosen the second locking component 332 (bolt) of the second locking assembly 33 (seat 8 height adjustment) and the third locking component 342 (bolt) of the third locking assembly 34 (seat 8 lateral adjustment);

[0083] ② Slide the second adjustment frame 31 up and down (directly connected to the seat 8), and change the height of the seat 8 by sliding the second sleeve component 331 (height guide tube) until the legs are naturally bent and the crossbar on the bicycle frame 1 is reached;

[0084] ③ Push the third adjustment frame 32 (fixedly connected to the second sleeve component 331) left and right, and adjust the lateral position of the seat 8 by sliding the third sleeve component 341 (lateral guide tube) (such as moving it to the outside of the frame 1 to expand the forward field of vision) until the operator's line of sight can cover the seeding tray and seed bed.

[0085] ④ Tighten the second locking component 332 and the third locking component 342 respectively, and fix the second and third adjusting brackets 32 by pressing the inner wall of the sleeve with bolts to complete the positioning of the seat 8.

[0086] 2. Driving and Steering Phase (Power Drive and Path Control)

[0087] After adjustment, the operator starts the power unit 4 (such as a diesel engine or electric motor), and the seeder enters the driving state:

[0088] Power transmission: The power mechanism 4 outputs power to the transmission system (such as gearbox, drive shaft) of the front wheel mechanism 6, driving the front wheel to rotate and realize the seeder to move forward or backward;

[0089] Steering control: The operator controls the front wheel steering (such as hydraulic power steering or mechanical linkage steering) through the first handle 21 (main steering handle) of the first adjustment mechanism 2. The angled part 7 (inclined surface) at the front of the frame 1 can reduce the friction between the front wheels and obstacles during steering and improve the passability of complex fields.

[0090] Center of gravity balance: The power mechanism 4 and the air suction mechanism 5 (including seed box, fan, etc.) are distributed behind the front wheel, and the overall center of gravity is close to the front wheel, which reduces the torque required for steering. The operator only needs to exert a little force to complete the steering, reducing labor intensity.

[0091] 3. Sowing Operation Stage (Precision Seeding and Sowing Execution)

[0092] After the seeder travels to the field to be planted, it activates the air suction mechanism 5 and the seed metering control device to enter the precision seeding process:

[0093] Air suction mechanism 5 starts: The fan starts running, forming a stable negative pressure at the seed suction plate, which is connected to the seed box through a pipe and uses the negative pressure to adsorb seeds;

[0094] Seed metering control: When the seeder travels to the preset plant spacing position, the seed metering device cuts off the negative pressure, and the seeds fall into the seed furrow opened by the furrow opener due to gravity;

[0095] Real-time monitoring: The operator can observe the sowing status in real time by moving the position of the seat 8. If missed sowing or blockage is found, the height of the handrail can be finely adjusted through the first adjustment mechanism 2 to quickly troubleshoot the problem.

[0096] 4. Storage / Transfer Phase (Equipment Organization and Relocation)

[0097] After the operation is completed, the seeder needs to be stored or transported for a short distance:

[0098] Adjustment mechanism reset: Lower the first adjustment frame 23 to the lowest height (for easy storage), adjust the second adjustment frame 31 to the narrowest horizontal position (to reduce the width of the equipment), and fix it by locking components;

[0099] Transfer travel: Start the power mechanism 4 and travel to the parking area at low speed. The angled part 7 of the frame 1 can avoid collision with the road shoulder or obstacles, improving the safety of the transfer.
