Description

Technical Field

[0001] This utility model belongs to the field of seeder technology, and in particular relates to a wheat seed and fertilizer simultaneous sowing machine. Background Technology

[0002] Wheat requires basal fertilizer application at sowing. Currently, there are two main methods for basal fertilizer application: First, fertilizing before sowing, where fertilizer is spread on the soil surface before rotary tillage, followed by sowing. This is labor-intensive and time-consuming, increasing labor costs, and can affect germination rates when soil moisture is poor. Second, simultaneous seed and fertilizer sowing. Existing seed and fertilizer sowing machines include a frame with a traction frame at the front. Above the frame, from front to back, are a fertilizer box and a seed box. Below the frame, from front to back, are a rotary tillage mechanism with a power transmission mechanism, a fertilizer application mechanism with a fertilizer disc, a seeding disc with seeding feet, and a press roller. The seed drill foot is connected to the seed box via the seeding pipe, and the traction frame is connected to the tractor or other machinery being pulled. After the land is tilled by rotary tillage and fertilized by the fertilization mechanism of the fertilization disc, the seeding mechanism sows the seeds, and finally the seed is pressed by the press roller. This seed-fertilizer simultaneous sowing machine has the following defects: 1. The entire sowing machine is long from front to back, resulting in high cost; 2. The center of gravity of the entire sowing machine is shifted to the rear, making it difficult to raise and lower the sowing machine; 3. Due to its long length from front to back, a large turning radius is required when turning, and the distance between the sowing machine and the end of the field is long when the tractor being pulled in front reaches the end of the field; 4. With the center of gravity shifted to the rear, tractors with the same power are prone to tipping over. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a wheat seed and fertilizer simultaneous sowing machine that is low in cost, easy to lift and lower, has a small turning radius, a short sowing distance to the field edge, and is less likely to cause the tractor to tilt.

[0004] To solve the above problems, the technical solution adopted by this utility model wheat seed and fertilizer co-sowing seeder is as follows: it includes a frame with a traction frame at the front end, and above the frame, from front to back, are a fertilizer box and a seed box. Below the frame, from front to back, are a rotary tillage mechanism with a power transmission mechanism, a sowing disc with a sowing drill foot, and a press roller. The sowing drill foot is connected to the seed box through a sowing pipe. The rotary tillage mechanism includes a rotary tiller frame and a rotary tillage shaft with rotary tillage blades. A fertilizer drill foot is provided on the rotary tiller frame behind the rotary tillage shaft. The fertilizer drill foot is connected to the fertilizer box through a fertilizer pipe.

[0005] Its additional technical features are: The fertilizer application drill foot includes a fixed rod located at the top and a fertilizer guiding channel located at the bottom. A fertilizer inlet pipe is provided above the fertilizer guiding channel and communicates with the fertilizer guiding channel. The fertilizer inlet pipe is connected to the fertilizer box through the fertilizer guiding pipe. The upper end of the fertilizer inlet pipe is inclined backward and upward; The lower end of the fertilizer channel slopes downwards and backwards.

[0006] Compared with existing technologies, the wheat seed and fertilizer co-sowing seeder provided by this utility model has the following advantages: Firstly, it includes a frame with a traction frame at the front end. Above the frame, from front to back, are a fertilizer box and a seed box. Below the frame, from front to back, are a rotary tillage mechanism with a power transmission mechanism, a seeding disc with a seeding foot, and a press roller. The seeding foot is connected to the seed box through a seeding pipe. The rotary tillage mechanism includes a rotary tiller frame and a rotary tillage shaft with rotary tillage blades. A fertilizer seeding foot is installed on the rotary tiller frame behind the rotary tillage shaft. The fertilizer seeding foot is connected to the fertilizer box through a fertilizer pipe. In this way, the fertilizer seeding foot is located on the rotary tillage mechanism, the distance occupied by the rotary tillage mechanism and the fertilizer seeding foot is short, the overall length of the wheat seed and fertilizer co-sowing seeder is shortened, the center of gravity is forward, and the overall material cost of the seeder is reduced. Firstly, the seeder is easy to raise and lower, requires a small turning radius when turning, and the distance between the seeder and the field edge is shorter when the tractor being towed in front reaches the edge, making it less likely for a tractor with the same power to tilt its head up. Secondly, the fertilizing drill foot includes a fixed rod at the top and a fertilizer guiding channel at the bottom. A fertilizer inlet pipe is installed above the fertilizer guiding channel and connects to the fertilizer tank. Fertilizer in the fertilizer tank enters the fertilizer inlet pipe through the fertilizer guiding pipe and then enters the soil through the fertilizer guiding channel, making the placement of each component more reasonable. Thirdly, the upper end of the fertilizer inlet pipe is inclined backward and upward, making the fertilization path smoother. Fourthly, the lower end of the fertilizer guiding channel is inclined backward and downward, avoiding blockage at the lower end of the fertilizer guiding channel when the seeder raises and lowers during wheat seed and fertilizer simultaneous sowing, making it more convenient to use.

[0008] The structure and operating principle of the wheat seed and fertilizer co-sowing seeder of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0009] like Figure 1 and Figure 2The diagram shows the structure of the wheat seed and fertilizer co-sowing seeder of this utility model. The wheat seed and fertilizer co-sowing seeder of this utility model includes a frame 2 with a traction frame 1 at the front end. Above the frame 2, from front to back, are a fertilizer box 3 and a seed box 4. Below the frame 2, from front to back, are a rotary tillage mechanism 6 with a power transmission mechanism 5, a sowing disc 8 with a sowing drill foot 7, and a press roller 11. The sowing drill foot 7 is connected to the seed box 4 through a sowing pipe 10. The rotary tillage mechanism 6 includes a rotary tiller frame 61 and a rotary tillage shaft 63 with rotary tillage blades 62. A fertilizer drill foot 9 is provided on the rotary tiller frame 61 behind the rotary tillage shaft 63. The fertilizer drill foot 9 is connected to the fertilizer box 3 through a fertilizer pipe 12.

[0010] In this way, the fertilizer seed drill foot 9 is set on the rotary tillage mechanism 6, and the distance between the rotary tillage mechanism 6 and the fertilizer seed drill foot 9 is short. The length of the entire wheat seed and fertilizer sowing machine is shortened, the center of gravity is forward, the material cost of the entire sowing machine is reduced, the sowing machine is easy to raise and lower, the turning radius required when turning is small, the distance between the sowing machine and the end of the field when the tractor towed in front reaches the end of the field is shorter, and the tractor with the same power is less likely to tilt.

[0011] The fertilizing drill foot 9 includes a fixed rod 91 at the top and a fertilizer guiding channel 92 at the bottom. A fertilizer inlet pipe 93, connected to the fertilizer guiding channel 92, is installed above it. The fertilizer inlet pipe 93 is connected to the fertilizer tank 3 via a fertilizer guiding pipe 94. Fertilizer in the fertilizer tank 3 enters the fertilizer inlet pipe 93 via the fertilizer guiding pipe 94, and then enters the soil through the fertilizer guiding channel 92. The placement of each component is more rational.

[0012] The upper end of the fertilizer inlet pipe 93 is tilted backward and upward, making the fertilizer application path smoother.

[0013] The lower end of the fertilizer guide channel 92 is tilted backward and downward, which avoids blockage of the lower end of the fertilizer guide channel when the wheat seed and fertilizer sowing machine is raised and lowered, making it more convenient to use.

[0014] The scope of protection of this utility model is not limited to the above embodiments. Any structure that is the same as or similar to the structure of the wheat seed and fertilizer co-planting seeder of this utility model falls within the scope of protection of this utility model.
