Description

Technical Field

[0001] This utility model belongs to the field of seeding technology, specifically relating to a multi-functional seeding machine for intercropping wheat, cotton, corn, and peppers, involving rotary tillage, fertilization, and mulching. Background Technology

[0002] In some parts of China, such as Xinjiang, there is a situation of "more than enough for one crop, but insufficient for two." Intercropping winter wheat with other crops can achieve two or more crops a year in the same field, increasing the land's multiple cropping index. Different crops have different needs and utilization patterns for resources such as light, water, and nutrients. Winter wheat plants are relatively short with shallow root systems, while corn plants are tall with deep root systems. Intercropping these two crops creates a three-dimensional structure with varying heights, allowing for stratified utilization of soil nutrients and light resources, reducing resource waste. Intercropping can yield additional crops without reducing winter wheat production, thereby increasing farmers' economic income. Some intercropped crops also have soil-improving effects.

[0003] However, most current seeders are designed for large-scale, mechanized, and full-process sowing of single crops, with few designed for intercropping, resulting in low adaptability. Utility Model Content

[0004] The purpose of this invention is to provide a multi-functional seeder for intercropping wheat, cotton, corn, and chili peppers, which involves rotary tillage, fertilization, and mulching, in order to solve the problems mentioned in the background art.

[0016] Figure 3 This is a rear view of the structure of this utility model. Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] like Figure 1-3 As shown, a multi-functional seeder for intercropping wheat, cotton, corn, and peppers, including a main frame 1, has a front frame 2 and a rear frame 3 on its front and rear sides respectively. A transmission device and a rotary tillage and soil-breaking device are arranged horizontally below the crossbeam of the front frame 2, and a fertilizer supply device is arranged above the crossbeam of the front frame 2. A drip irrigation tape laying device is arranged on the main frame 1. A seedbed pre-compression and leveling device, a film laying device, and a furrowing seeder 22 are arranged sequentially from front to back below the rear frame 3. The transmission device includes an intermediate transmission box 4 connected to the output shaft of the tractor gearbox. Two gearboxes 5 are arranged on both sides of the intermediate transmission box 4. The intermediate transmission box 4 transmits power to the two gearboxes 5 through a transmission shaft 6.

[0019] Furthermore, the rotary tillage and soil-breaking device includes a rotary tillage blade shaft 7 mounted on a drive shaft 6, a rotary tillage blade disc 8 mounted on the rotary tillage blade shaft 7, an arc-shaped rotary tillage blade 9 mounted on the rotary tillage blade disc 8, and soil-breaking plow blades 10 mounted on the outer walls of the two side gearboxes 5; the soil is turned over by the arc-shaped rotary tillage blades 9, and then the soil-breaking plow blades 10 break up the hard clods in the soil, making the soil loose and easy to cultivate.

[0020] Furthermore, the fertilizer supply device includes a fertilizer storage box 11 at the top, and a fertilizer discharge shaft 12 at the bottom of the fertilizer storage box 11. The fertilizer discharge shaft 12 is driven to rotate by a motor 13 located on the outside of the fertilizer storage box 11. Several wheel-type outer grooves 25 connected to the bottom of the fertilizer storage box 11 are installed on the fertilizer discharge shaft 12. The wheel-type outer grooves 25 are connected to a fertilizer spreading plate 14 located on the outside of the fertilizer storage box 11. The motor 13 drives the fertilizer discharge shaft 12 to rotate, which draws out the fertilizer in the fertilizer storage box 11 and flows out along the wheel-type outer grooves 25 and the fertilizer spreading plate 14 for fertilization.

[0021] Furthermore, the seedbed pre-compression and leveling device is a pressure roller 15 with a trapezoidal cross-section; the trapezoidal pressure roller 15 produces a ridge surface that is exactly trapezoidal, making the ridge surface flatter and less prone to misalignment during sowing.

[0022] Furthermore, the film-laying device includes a film-laying trencher 16 located near the press roller 15. A film-pressing wheel 17 is located at the rear of the film-laying trencher 16. The film-pressing wheel 17 is connected to the press roller 15 via a film-pressing wheel connecting beam 18. Film-covering wheels 19 are located on both sides of the film-pressing wheel 17. The film-covering wheels 19 are connected to the rear frame 3 via a connecting rod 20. A film-spreading roller 21 for placing the film is located on the upper part of the rear frame 3. The film on the film-spreading roller 21 is first manually placed on the ground. As the machine moves forward, the film is continuously pulled out and spread out under the action of film friction. Then, the film-pressing wheel 17 presses the edge of the spread film into the shallow soil layer to prevent the film from being blown away by the wind and ensure that it is laid flat. The film-covering wheels 19 fill the soil trenches pressed out by the film-pressing wheel 17 with soil to further fix the edge of the film and enhance stability.

[0023] Furthermore, the furrowing seeder 22 is a 24-hole duckbill seeder; this seeder is purchased directly from the market.

[0024] Furthermore, the curved rotary tiller 9 is provided with an outer cover 23, and the fertilizer spreading plate 14 is located above the outer cover 23; the outer cover 23 protects the curved rotary tiller 9 from injuring people and prevents soil from flying around and affecting the environment.

[0025] Furthermore, the pressing roller 15 is connected to the main frame 1 via the connecting column 24.

[0026] The working principle of this utility model is as follows: First, the fertilizer supply device evenly spreads fertilizer on the sowing area through the fertilizer spreading plate 14. The rotary tillage and soil breaking device, pulled by the tractor, turns over the soil and mixes the soil and fertilizer. The seedbed pre-compression and leveling device flattens and shapes the rotary tilled soil and fertilizer mixture into a trapezoidal seedbed. The film laying device performs ditching, film laying, film pressing, and soil covering. Finally, the two ditching seeders 22 sow the seeds. The whole process is compact and continuous, with high work efficiency, and is suitable for intercropping winter wheat and cotton in Xinjiang.

[0027] This utility model allows for adjustments to the installation positions of the fertilizer supply device, rotary tillage and soil-crushing device, seedbed pre-compression and leveling device, film-laying device, and furrowing seeder 22 on the frame 1 according to different crops, thus making it suitable for cultivating a variety of crops with high adaptability.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
