Description

Technical Field

[0001] The utility model relates to the technical field of cotton agricultural machinery, and particularly relates to a seeder for cotton plot experiments. Background Technique

[0002] When carrying out agricultural planting, the main purpose of cotton plot experiments is to determine the suitable seasons for planting cotton in specific regions by adopting different sowing methods at different times. At the same time, variety comparison experiments are also carried out to select cotton varieties suitable for planting in this region, providing a basis for whether large-scale planting can be carried out in the future. At the same time, with the popularization and application of the dry seeding and wet emergence technology in northern Xinjiang, the precise seeding technology is widely used, and the mechanical seeding rate reaches 100%. The precise seeding of one seed per hole is fully realized. The large-scale film-laying and seeding combined operation machines of models 2MBJ-2 / 12 and 2MBJ-3 / 12 produced by local agricultural machinery enterprises in Xinjiang are mostly used, which can greatly improve the efficiency of film-laying and seeding integration.

[0003] When sowing cotton seeds into the test field in the prior art, a drum-type seeding period is mostly adopted. However, due to the short baffle on the back of the duckbill of the current cotton drum seeding device and the use of a single external baffle, when the film-laying and seeding combined operation machine sows, cotton seeds are likely to leak from the duckbill of the seeder or the cotton seeds float on the plastic film due to the subsidence of the soil in the seed hole, resulting in the phenomenon of empty holes and missing seeds, reducing the seeding efficiency and quality. In addition, most of the existing seeders adopt pointed duckbills, with a relatively shallow sowing depth, less soil covering for the "holes" formed, insufficient compaction, and it is easy to form floating seeds after dripping water, affecting the emergence rate and emergence quality. Therefore, a seeder for cotton plot experiments is proposed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a seeder for cotton plot experiments to solve the problems of missing seeds and empty holes caused by cotton seeds floating on the surface due to the working failure of the drum seeder and the problem of emergence with seed shells caused by relatively shallow soil covering for cotton seeds when using a pointed duckbill seeder during the film-laying and seeding process as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A seeder for cotton plot experiments includes an external seed discharging baffle. Arc-shaped buckles are respectively fixedly connected to both sides of the external seed discharging baffle. A hinged support is fixedly connected to the middle and lower positions of the arc-shaped buckles. An articulated shaft rod is rotatably connected between the two hinged supports. A moving duckbill is fixedly connected to the front position of the articulated shaft rod. An articulated internal baffle is fixedly connected to the top end of the moving duckbill. Reinforcing rib strips are fixedly connected to the surface of the moving duckbill. The reinforcing rib strips and the articulated internal baffle are fixedly connected together through a connecting plate.

[0007] Preferably, a fixed duckbill is provided on the inner side of the external seed discharging baffle. An internal diversion opening is integrally formed on the inner side of the fixed duckbill. The fixed duckbill is configured in an internal square structure, and the internal diversion opening is configured in a trapezoidal funnel-shaped structure.

[0008] Preferably, positioning holes are respectively formed at the upper and lower ends on both sides of the arc-shaped buckle plate. An arc-shaped support plate is fixedly connected to the bottom of the arc-shaped buckle plate. The arc-shaped support plate is configured in an upper-long and lower-short structure.

[0009] Preferably, the moving duckbill is configured in a "U" shape. A compression spring is fixedly connected to the middle position at the bottom of the moving duckbill. The compression spring is hooked and connected with the arc-shaped support plate. The opening degree of the moving duckbill is 1.8 - 2 cm. The connection between the moving duckbill and the hinged internal baffle forms an "L" shape.

[0010] Preferably, the hinged internal baffle is configured in a trapezoidal shape. The length of the external seed discharging baffle is 6 - 7 cm. The external seed discharging baffle is configured in a "concave" shape.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, by providing the external seed discharging baffle, internal diversion opening, compression spring, moving duckbill and hinged internal baffle, it is convenient for the seeder used for cotton plot experiments to assemble the internal and external double baffle structure composed of the external seed discharging baffle, internal diversion opening, compression spring, moving duckbill and hinged internal baffle to the arc-shaped plate on the back of the seeder before use, so as to limit the depth and width of seed discharging when the seeder rolls downward, effectively reduce the seed discharging space, prevent seeds from running off and leaking, reduce the situation of seeds floating on the film surface, reduce the hole rate, and improve the emergence rate. At the same time, compared with the original duckbill structure of the seeder, the present patent adopts an internal and external double-layer hinged baffle type square duckbill with a deeper sowing depth, and it can also form a "concave" seed hole with a thicker soil covering than the pointed duckbill, which is compacted, beneficial to moisture preservation and emergence of cotton seeds, can effectively avoid the occurrence of the situation of emerging with shells and floating seeds after sowing, and improve the emergence quality.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1 - 3 , the present invention provides a technical solution:

[0019] A seeder for cotton plot experiments includes an external seed discharging baffle 1. Arc-shaped buckle plates 2 are respectively fixedly connected to both sides of the external seed discharging baffle 1. A hinged support 4 is fixedly connected to the lower middle position of the arc-shaped buckle plate 2. A hinged shaft rod 11 is rotatably connected between the two hinged supports 4. A moving duckbill 5 is fixedly connected to the front position of the hinged shaft rod 11. A hinged built-in baffle 7 is fixedly connected to the top end of the moving duckbill 5. A reinforcing rib 6 is fixedly connected to the surface of the moving duckbill 5. The reinforcing rib 6 and the hinged built-in baffle 7 are fixedly connected together through a connecting plate 10.

[0020] As Figure 1 and Figure 2 shown, a fixed duckbill 13 is provided inside the external seed discharging baffle 1. An internal diversion opening 3 is integrally formed inside the fixed duckbill 13. The outer shape of the fixed duckbill 13 is set as an internal square structure. The outer shape of the internal diversion opening 3 is set as a trapezoidal funnel-shaped structure. When the entire duckbill structure is opened as the seeder rolls, the trapezoidal funnel-shaped structure of the internal diversion opening 3 can play a role in limiting the seed discharging space and secondarily limiting the cotton seeds from falling into the seed holes; Positioning holes 12 are respectively opened at the upper and lower ends on both sides of the arc-shaped buckle plate 2. An arc-shaped support plate 8 is fixedly connected to the bottom position of the arc-shaped buckle plate 2. The outer shape of the arc-shaped support plate 8 is set as a structure with a longer upper part and a shorter lower part. This structure is conducive to the entire duckbill structure being quickly assembled to the arc-shaped plate on the back of the seeder through the cooperation of the arc-shaped support plate 8 and the arc-shaped support plate 8.

[0021] As Figure 1 , Figure 2 and Figure 3As shown, the moving duckbill 5 has a "U"-shaped structure. A compression spring 9 is fixedly connected to the middle position at the bottom of the moving duckbill 5. The compression spring 9 is hooked and connected with the arc-shaped support plate 8. The opening degree of the moving duckbill 5 is 1.8 - 2 cm. The connection between the moving duckbill 5 and the hinged built-in baffle 7 forms an "L"-shaped structure. In this structure, the setting of the compression spring 9 mainly plays a role in pulling the moving duckbill 5 to open and close and return to its position. The hinged built-in baffle 7 has a trapezoidal structure. The length of the external seed outlet baffle 1 is 6 - 7 cm. The external seed outlet baffle 1 has a "concave"-shaped structure. When the duckbill structure on the seeder is opened and cooperates to realize cotton seed sowing, the external seed outlet baffle 1 can first contact the ground and insert into the soil to fix and support and excavate the seed hole during the rolling of the new seeder. After the cotton seed falls into the seed hole in cooperation with the moving duckbill 5, a sunken square seed hole with a depth of 1.5 - 2 cm is dug above the seed hole at the same time, and the cotton seed is covered with soil 2 - 3 cm to conserve moisture and increase temperature.

[0022] Working process: Before using the seeder for cotton plot experiments, when assembling the seeder, the present utility model optimizes and improves the duckbill of the original drum seeder. Specifically, a trapezoidal seed outlet baffle is adopted inside the hinged built-in baffle 7, so that it can form an inner and outer double-layer baffle with the external seed outlet baffle 1, thereby being able to limit the depth and width of seed outlet when the seeder rolls downward. After the improvement operation is completed, the arc-shaped buckle plate 2 and the arc-shaped plate on the back of the seeder can be fixedly connected together through the bolts passing through the arc-shaped buckle plate 2, so that multiple seeder duckbill structures can be quickly assembled onto the arc-shaped plate on the back of the seeder. Then, when the seeder is driven by a traction locomotive and rolls forward on the cotton plot experimental field, as the external seed outlet baffle 1 inserts into the soil 3 - 4 cm along with the seeder drum, with the height of the hinged built-in baffle 7 being close to the height of the external seed outlet baffle 1, the moving duckbill 5 squeezes the compression spring 9 to open, so that the hinged built-in baffle 7 removes the coverage of the built-in diversion port 3, and the cotton seeds slide along the channel into the built-in diversion port 3, ensuring that the cotton seeds accurately fall into the seed holes and realizing the sowing work. Finally, the soil covering roller and the soil scraping wheel complete the soil covering. At the same time, under the overall sowing operation, compared with the duckbill structure of the original drum seeder, the adaptability of the duckbill component of the new seeder is good, and the sowing efficiency and quality are improved by means of the trapezoidal built-in baffle, realizing full emergence in one sowing.

[0023] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
