Description

Technical Field

[0001] This utility model belongs to the field of sowing machinery and equipment, and in particular relates to a seed and fertilizer sowing device. Background Technology

[0002] Seeds require sowing devices during the sowing process. Existing sowing devices are planting machines that use seeds as the sowing target. Seeders used for a certain crop are often named after the crop type, such as grain strip seeders, corn hill seeders, cotton seeders, pasture broadcasters, wheat seeders, etc. After sowing, existing seeders require fertilization again, and the two cannot be done at the same time, which is time-consuming, labor-intensive, and reduces sowing efficiency.

[0003] Simultaneous sowing of seeds and fertilizer (seed-fertilizer co-sowing) is a modern agricultural technology that uses a seeder to precisely apply seeds and fertilizer at the same time, offering several advantages: 1. Increased efficiency - Saves time and labor: Sowing and fertilization are completed in one step, reducing the number of field operations and lowering labor intensity. - Precise matching: Mechanical control of the distance between fertilizer and seeds (usually 3-5 cm below the seed) avoids human error. 2. Promotes crop growth: - Rapid nutrient absorption: Fertilizer is applied close to the seed, allowing seedling roots to access nutrients promptly and accelerating early growth. - Reduced waste: Deep application of fertilizer reduces volatilization (e.g., nitrogen fertilizer) or loss (e.g., phosphorus and potassium fertilizer), increasing utilization by 15-30%. 3. Increased yield and optimized quality - Balanced fertilization: The simultaneous use of slow-release or controlled-release fertilizers provides stable nutrient supply, increasing yield (experimental data show a 5-15% increase). - Enhanced stress resistance: Sufficient basic nutrients help crops resist early adverse conditions such as drought and low temperatures. 4. Cost Savings - Reduced Machinery Fuel Consumption: Reducing the use of machinery for separate fertilization saves approximately 20-30% on fuel costs. - Reduced Fertilizer Usage: Precise application reduces the risk of over-fertilization, saving 5-10 kg of fertilizer per acre. 5. Environmental Benefits - Reduced Non-point Source Pollution: Precise fertilization reduces fertilizer leaching, mitigating the risk of nitrate pollution in groundwater.

[0004] Most existing seed and fertilizer co-sowing devices are new structural products, while there are a large number of separate seeding and fertilization devices in existing fields. Therefore, how to improve the existing equipment to meet the requirements of seed and fertilizer co-sowing is a problem that needs to be solved. Utility Model Content

[0005] This invention addresses the technical problem that existing field sowing equipment cannot achieve simultaneous sowing of seeds and fertilizers, and proposes a cleverly designed device that can be improved upon existing sowing equipment to achieve simultaneous sowing of seeds and fertilizers.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a seed and fertilizer simultaneous sowing device, including a frame and a traction frame disposed at the front end of the frame.

A distributing chamber is connected to the bottom of the hopper. The distributing chamber is disc-shaped and contains a distributing plate. A distributing plate is disposed on the side wall of the distributing plate. The distributing plate is coaxial with the distributing chamber, and the axial direction of the distributing plate is perpendicular to the direction of material falling from the hopper. A gap is provided between the end of the distributing plate and the inner wall of the distributing chamber. The bottom of the distributing chamber is connected to the seeder via a pipe, and the distributing plate is rotatably disposed within the distributing chamber.

[0007] Preferably, the walking wheels are provided with a rotating shaft, and the walking wheels are rotatably mounted on the frame via the rotating shaft. A drive gear is provided on the rotating shaft of any walking wheel, and a drive shaft is provided on the material distribution plate. The drive shaft passes through the material distribution cavity, and a driven gear is fitted on one end of the drive shaft that extends out of the material distribution cavity.

Detailed Implementation

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1, as Figure 1 , Figure 2 As shown, this embodiment aims to improve upon the technical problem that existing seeders do not have the ability to simultaneously sow seeds and fertilizers, so as to enable existing seeders to simultaneously sow seeds and fertilizers. To achieve the above objective, the seed and fertilizer simultaneous sowing device provided in this embodiment includes a frame 1 and a traction frame 11 set at the front end of the frame 1. The traction frame 11 is mainly used to connect with traveling machinery such as tractors. Traveling wheels 12 are set on both sides of the frame 1. The traveling wheels 12 are rotatably mounted on the frame 1. The rotation of the traveling wheels 12 is mainly achieved by the pulling of the traveling machinery. A hopper 2 is set on the frame 1, and a seeder 6 is set at the bottom of the frame 1. The hopper 2 and the seeder 6 are connected by a pipe 7. The above structure is the structure of a common existing seeder. Therefore, it will not be described in detail in this embodiment.

[0019] Considering that if seeds and fertilizer are to be sown simultaneously, they need to enter the pipe 7 at the same time and then be sown into the soil through the seeder 6. Therefore, to meet the requirements of simultaneous storage and mixing of seeds and fertilizer, in this embodiment, a partition 21 is provided in the middle of the hopper 2. The partition 21 divides the hopper 2 into a seed chamber and a fertilizer chamber, which are arranged in front and behind. In this embodiment, the direction of the traction frame 11 is considered front. In this way, rotating clockwise, fertilizer is stored first and then seeds are stored, which makes it more convenient to mix seeds and fertilizer.

[0020] To achieve the mixing of seeds and fertilizer, a distribution chamber 4 is connected to the bottom of the hopper 2. The distribution chamber 4 is disc-shaped and contains a distribution plate 41. Distribution plates 42 are evenly distributed on the side walls of the distribution plate 41. In this embodiment, eight distribution plates 42 are arranged on the distribution plate 41, thus dividing the distribution chamber 4 into eight smaller chambers. In this embodiment, the distribution plate 41 is coaxially arranged with the distribution chamber 4, and the axial direction of the distribution plate 41 is perpendicular to the material discharge direction of the hopper 2. A gap is provided between the end of the distribution plate 42 and the inner wall of the distribution chamber 4. The main purpose of the gap is to ensure that the distribution plate 41 can rotate without causing the seeds and fertilizer to fall out. At the same time, the bottom of the distribution chamber 4 is connected to the seeder 6 through a pipe 7. In this way, as the distribution plate 41 rotates, the fertilizer first falls into the small chamber, then the seeds fall in, and finally, when it rotates to the bottom, it enters the pipe 7 and eventually enters the seeder 6.

[0021] To reduce energy consumption, in this embodiment, a rotating shaft 121 is provided on the walking wheel 12. The walking wheel 12 is rotatably mounted on the frame 1 via the rotating shaft 121. A drive gear 122 is provided on the rotating shaft 121 of any walking wheel 12. At the same time, a drive shaft 43 is provided on the distributing plate 41. The drive shaft 43 extends through the distributing chamber 4, and a driven gear 44 is fitted on the end of the drive shaft 43 extending out of the distributing chamber 4. The driven gear 44 and the drive gear 122 are connected by a chain 5. In this way, while the walking mechanism pulls the walking wheel 12, it drives the rotating shaft 121 to rotate. The movement of the rotating shaft 121 drives the rotation of the drive shaft 43, and at the same time, it drives the rotation of the distributing plate 41, thus completing the acquisition of seeds and fertilizers. Meanwhile, due to the rotation of the distributing plate 41, the seeds and fertilizers are mixed in the small chamber.

[0022] To control the ratio of fertilizer to seeds, in this embodiment, an adjusting cavity 3 is also provided between the hopper 2 and the distributing cavity 4. The adjusting cavity 3 is square in shape, with a partition 21 extending into it. An adjusting plate 32 is provided in the adjusting cavity 3, rotatably mounted on both sides of the partition 21. An adjusting shaft 33 is provided at the end of the adjusting plate 32 away from the partition 21, extending out of the adjusting cavity 3. A locking nut 34 is fitted onto the end of the adjusting shaft 33 extending out of the adjusting cavity 3. The adjusting shaft 33 has threads that cooperate with the locking nut 34. An arc-shaped slot 31 for the adjustment shaft 33 to move is provided on the side wall of the adjusting cavity 3. In this way, by controlling the tilt angle of the adjusting plate 32, the size of the discharge openings of the fertilizer cavity and the seed cavity can be controlled, thereby controlling the amount of seeds and fertilizer falling. Since the ratio is generally fixed during the tillage process, manual adjustment not only reduces costs but is also simple and reliable.

[0023] In order to complete multiple seed sowings at once, the frame 1 is provided with at least two spaced hoppers 2. In this embodiment, an improvement is made to the existing common seeder, which is provided with four hoppers 2. It should be noted that the four hoppers 2 share a drive shaft 43, that is, a drive shaft 43 passes through the material distribution chamber 4 below the four hoppers 2.

[0024] The above settings effectively enable simultaneous sowing of seeds and fertilizers on existing equipment that can only sow seeds. The only modification required is at the hopper 2, which meets the usage requirements while keeping the improvement cost low.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
