Description

Technical Field

[0001] This utility model relates to the field of seeding machinery and equipment technology, and in particular to a seed-collecting structure and seed collector for a wheat seeder, and a wheat seeder. Background Technology

[0002] Wheat is a high-density crop, and an appropriate planting density is beneficial for improving the uniformity of wheat growth, enhancing its resistance to lodging, and increasing wheat yield. In order to improve the appropriateness of wheat planting density, existing technologies use hill seeders for sowing. During the sowing process, it is necessary to put an appropriate number of wheat seeds into each hill. Therefore, before the wheat seeds are put into the soil, a seed-collecting mechanism set in the hill seeder needs to take out an appropriate number of wheat seeds at the seed-collecting position. Then, the seed-collecting nozzle set in the hill seeder will put the wheat seeds obtained at the seed-collecting position into the soil.

[0003] Furthermore, the hill-planting seeder mainly includes a roller assembly, a seed-collecting mechanism, and a seed-sowing component. The roller assembly forms a seed storage cavity for storing seeds. The seed-collecting mechanism is mounted on a support wheel of the roller assembly and mainly includes a seed collector, a rotating shaft, a swing arm, and a torsion spring. The seed-sowing component is mounted on the outer wheel surface of the support wheel. Furthermore, the wheel assembly unit has a mounting groove spaced radially inward on its inner circumferential side for mounting the seed collector. A seed collector is rotatably mounted in the mounting groove to collect seeds. The seed collector is mounted on a rotating shaft, and a torsion spring is sleeved on the rotating shaft. The first torsion arm on the torsion spring stops against the seed collector, and the second torsion arm on the torsion spring stops against the support wheel. One end of the rotating shaft is connected to the swing arm. The roller assembly is also equipped with a swing drive rail. The swing drive rail, the swing arm, and the torsion spring work together to drive the seed collector to rotate in the mounting groove. The seed collector is equipped with a seed-collecting hole. The rotation of the seed collector in the mounting groove causes the seed-collecting hole to deflect, giving it a seed-collecting position and a seed-dispensing position. The seed-collecting hole collects seeds at the seed-collecting position and dispenses seeds at the seed-dispensing position.

[0004] Furthermore, during the seed-collecting process using the seed collector, in order to achieve seed cleaning, seeds that do not fall into the seed-collecting hole are blocked and removed, ensuring that only seeds that fall into the seed-collecting hole are deflected from the seed-collecting position to the seed-dispensing position. Therefore, an elastic seed-cleaning component needs to be installed on one side of the mounting trough. This component is installed on the inner wheel surface and located on one side of the seed collector. As the seed collector deflects from the seed-dispensing position to the seed-dispensing position, the elastic seed-cleaning component sweeps across the outer wall of the seed collector, blocking and removing seeds that do not fall into the seed-collecting hole. Additionally, the support wheel has multiple seed-dispensing channels corresponding to multiple mounting troughs. These channels are connected to the mounting troughs, and the outer sides of the seed-dispensing channels extend out of the support wheel to form seed-dispensing openings. Seed-sowing nozzles are installed on the outer sides of these seed-dispensing openings. By controlling the opening timing of these nozzles, the timing of seed dispensing is controlled, allowing seeds to be dispensed into the seed-dispensing openings via the seed collector.

[0005] However, due to the differences in wheat seed size, especially between different varieties, and the deficiencies in the design of the seed-collecting structure and its associated seed-collecting pits in existing seed extractors, the adaptability and accuracy of these extractors for wheat seed collection need improvement. Furthermore, the seed-collecting structure is a crucial component of the seed extractor, largely determining its adaptability and accuracy in wheat seed collection. Therefore, there is an urgent need for a seed-collecting structure that improves the adaptability and accuracy of seed extractors for wheat seed collection. Summary of the Invention

[0006] The purpose of this utility model is to overcome at least one deficiency of the prior art and provide a seed-taking structure for a wheat seeder that is beneficial to improving the reliability and stability of seed taking; in addition, it also provides a seed taker for a wheat seeder and a wheat seeder.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0008] According to one aspect of this application, a seed-collecting structure for a wheat seeder is provided, comprising:

[0009] The body has an arc-shaped surface on its radially outer side. The arc-shaped surface has several seed-collecting pits that are concave relative to the arc-shaped surface and used for collecting wheat seeds. One end of each seed-collecting pit facing the radially outer side of the body is open, forming a seed passage for the wheat seeds to pass through. The number of wheat seeds that each seed-collecting pit can hold is N, and the volume of each seed-collecting pit is M*N. The range of M is 56.00 ≤ M ≤ 73.00, and N is a positive integer from 1 to 6. The unit of volume is mm³.

[0010] The beneficial effects of this utility model are as follows: In this embodiment, the radially outer side of the main body is provided with an arc-shaped surface, and the seed-collecting hole is set on the arc-shaped surface. During the process of the main body collecting seeds by swinging, it helps to reduce the resistance between the radially outer side of the main body and the wheat seeds stored in the seed storage cavity, and facilitates the movement of the wheat seeds stored in the seed storage cavity towards the seed-collecting hole and falling into the seed-collecting hole; furthermore, the volume of the seed-collecting hole in this embodiment is M*N, where N is the number of wheat seeds that the seed-collecting hole can hold, and M is in the range of 56.00≤ A value of M ≤ 73.00 ensures that the volume of the seed collection hole is suitable, providing sufficient space for a certain number of wheat seeds in each hole, thereby improving the reliability and stability of seed collection. Furthermore, the range of M can cover the volume range of various single wheat seeds, which is beneficial to improving the applicability of the seed collection hole to various single wheat seeds. Therefore, using the seed collection structure in this embodiment as the seed collection component in the seed collector is beneficial to improving the reliability and stability of seed collection.

[0011] In addition, based on the above technical solution, the present invention can be further improved as follows, and can also have the following additional technical features.

[0012] According to one embodiment of this application, the range of M is 60.00≤M≤70.00.

[0013] In this embodiment, the range of M is 60.00≤M≤70.00. The numerical range of M is closer to the volume range of a single wheat seed, which is beneficial for providing suitable and sufficient space for a certain number of wheat seeds in each seed collection hole. Furthermore, the range of M can cover the volume range of multiple single wheat seeds, which is beneficial for improving the applicability of the seed collection hole to collecting multiple single wheat seeds.

[0014] According to one embodiment of this application, when the wheat seed variety is Xindong 52, the range of M is 63.00≤M≤73.00;

[0015] When the wheat seed variety is Xindong 22 or Xinchun 38, the range of M is 56.00≤M≤66.00;

[0016] When the wheat seed variety is Xinchun 38 spring sowing, the range of M is 59.00≤M≤69.00.

[0017] In this embodiment, when the wheat seed variety is Xindong 52, the range of M is 63.00≤M≤73.00. This range of M values ​​is closer to the volume range of a single grain of Xindong 52 wheat, which helps to provide suitable and sufficient space for a certain number of Xindong 52 wheat seeds in each seed collection hole. Similarly, when the wheat seed variety is Xindong 22 or Xinchun 38, the range of M is 56.00≤M≤66.00. This range of M values ​​is closer to that of Xindong 22 or Xinchun 38. The volume range of a single wheat seed in a 38-pack is conducive to providing suitable and sufficient space in each seed collection hole for a certain number of wheat seeds of the Xin Dong 22 or Xin Chun 38-pack varieties. Similarly, when the wheat seed variety is Xin Chun 38 spring-sown, the range of M is 59.00≤M≤69.00. The value range of M is closer to the volume range of a single wheat seed of the Xin Chun 38 spring-sown variety, which is conducive to providing suitable and sufficient space in each seed collection hole for a certain number of wheat seeds of the Xin Chun 38 spring-sown variety.

[0018] According to one embodiment of this application, there are two seed-collecting holes, which are spaced apart along the length of the body.

[0019] In this embodiment, there are two seed-collecting holes, which simplifies the structure of the main body, facilitates its production, and helps reduce the production cost. In addition, having two seed-collecting holes allows for simultaneous seed collection in the seed-collecting area, which helps increase the amount of seeds collected each time, thereby helping to meet the requirements for wheat seed input.

[0020] According to one embodiment of this application, the main body is further provided with an inclined surface one and an inclined surface two, the inclined surface one and the inclined surface two are arranged at an angle, and the two ends of the arc-shaped surface in the circumferential direction are respectively connected to the inclined surface one and the inclined surface two; the main body is further provided with a snap-fit ​​protrusion for snapping, the snap-fit ​​protrusion is connected to one of the inclined surface one and the inclined surface two.

[0021] In this embodiment, by connecting a snap-fit ​​protrusion to one of the inclined surfaces, the seed extractor can be designed as a split structure, and the main body can be used as part of the seed extractor. This facilitates the connection of the main body to the other parts of the seed extractor through the snap-fit ​​protrusion. In addition, using the main body as part of the seed extractor makes it easier to produce the main body and then snap the snap-fit ​​protrusion into the slots provided on the other parts of the seed extractor. This allows the produced main body to be connected to the other parts of the seed extractor to form the seed extractor, thereby reducing the difficulty of production and processing of the seed extractor and reducing its production cost.

[0022] According to one embodiment of this application, the body is further provided with a snap-fit ​​groove for snapping, the snap-fit ​​groove being disposed on the other surface of the first inclined surface and the second inclined surface.

[0023] In this embodiment, a snap-fit ​​groove is connected to another surface of inclined surface one and inclined surface two, which facilitates the design of the seed extractor as a split structure and makes the main body a part of the seed extractor. This allows the main body to be connected to other parts of the seed extractor through the snap-fit ​​groove to form the seed extractor. In addition, making the main body a part of the seed extractor facilitates the production of the main body. Then, the protrusions on other parts of the seed extractor are snapped into the snap-fit ​​groove, which realizes the connection of the produced main body to other parts of the seed extractor to form the seed extractor. This helps to reduce the production and processing difficulty of the seed extractor and reduce the production cost of the seed extractor.

[0024] According to one embodiment of this application, the seed is round in shape through the opening, and the arc-shaped surface is arc-shaped.

[0025] In this embodiment, the seed passage opening is round, which facilitates the falling of wheat seeds into the seed retrieval hole when they approach the seed passage opening in the seed storage cavity, thus improving the smoothness of seed retrieval. In addition, the arc-shaped surface further reduces the resistance between the radial outer surface of the body and the wheat seeds stored in the seed storage cavity during the seed retrieval process by swinging the body.

[0026] According to one embodiment of this application, the seed-collecting hole has a semi-elliptical cavity structure or a semi-pebble cavity structure.

[0027] In this embodiment, the seed-collecting hole has a semi-elliptical cavity structure or a semi-pebble cavity structure, which increases the degree of matching between the inner wall contour of the seed-collecting hole and the outer contour of the wheat seed, which is beneficial for the seed-collecting hole to contain the wheat seed. In addition, it makes the inner wall of the seed-collecting hole smooth, which is beneficial for the wheat seed to be smoothly thrown out of the seed-collecting hole when the seed-collecting hole is placed in the seed-throwing area.

[0028] According to one embodiment of this application, the seed-collecting cavity has a frustum-shaped cavity structure, with the end of the seed-collecting cavity near the seed passage being the larger diameter end and the end of the seed-collecting cavity away from the seed passage being the smaller diameter end.

[0029] In this embodiment, the seed-collecting hole has a frustum-shaped cavity structure. The end of the seed-collecting hole closest to the seed passage is the larger diameter end, which facilitates the falling of wheat seeds from the seed storage cavity into the seed-collecting hole when they approach the seed passage, thus improving the smoothness of seed collection. In addition, it makes the inner sidewall of the seed-collecting hole smooth, which is beneficial for the smooth dispensing of wheat seeds from the seed-collecting hole to the outside when the seed-collecting hole is used for sowing in the sowing area.

[0030] According to one embodiment of this application, the bottom of the seed-taking hole has a hemispherical concave structure, and the center of the circle corresponding to the bottom of the seed-taking hole coincides with the center of the circle corresponding to the small diameter end.

[0031] In this embodiment, the bottom of the seed-collecting hole has a hemispherical concave structure, which helps to increase the depth of the seed-collecting hole and thus increase its volume. Furthermore, the center of the circle corresponding to the bottom of the seed-collecting hole coincides with the center of the circle corresponding to the small diameter end, which facilitates the even distribution of wheat seeds falling into the seed-collecting hole.

[0032] According to one embodiment of this application, the arc-shaped surface is further provided with a plurality of injection molding process grooves, the injection molding process grooves are recessed relative to the arc-shaped surface, and the injection molding process grooves are located on one side of the seed-taking hole, and the body is injection molded by injection molding process.

[0033] In this embodiment, several injection molding process grooves are provided on the arc-shaped surface. During the injection molding process of the main body, the protruding limiting blocks located at the injection molding process grooves can be used as positioning parts for the main body molding, which is beneficial for the main body to be injection molded. In addition, during the injection molding process, the position of the protruding limiting block in the injection molding process groove is the protruding limiting block. The protruding limiting block is adhered to the main body. The adhesion relationship between the protruding limiting block and the main body can be used to demold the injection molded main body, thereby improving the convenience of demolding the injection molded main body.

[0034] According to another aspect of this application, a seed taker for a wheat seeder is provided, comprising:

[0035] Support structure;

[0036] The seed-collecting structure for the wheat seeder described above has its main body detachably mounted on the support structure.

[0037] The seed extractor for a wheat planter in this embodiment includes a support structure and the aforementioned seed extractor structure. This design helps reduce the resistance between the radially outer surface of the main body and the wheat seeds stored in the seed storage cavity, and facilitates the movement of the wheat seeds stored in the seed storage cavity towards the seed extractor and their entry into the seed extractor. Furthermore, it allows for a suitable volume of the seed extractor, ensuring that each seed extractor has sufficient space to accommodate a certain number of wheat seeds, thereby improving the reliability and stability of seed extraction from each seed extractor. Furthermore, it enhances the applicability of the seed extractor to extracting various single-grain wheat seeds, further improving the reliability and stability of the seed extractor. Moreover, the main body is detachably mounted on the support structure, allowing for the separate production of the support structure and the seed extractor structure. Installing the seed extractor structure on the support structure to form the seed extractor reduces production costs and facilitates maintenance and replacement of the seed extractor structure.

[0038] According to another aspect of this application, a wheat seeder is provided, comprising:

[0039] A seeding assembly, wherein the seeding assembly is provided with a seed storage chamber for storing wheat seeds;

[0040] The seed collectors described above for wheat planters are provided with a plurality of seed collectors spaced apart circumferentially inside the planting assembly. During the rolling of the planting assembly, the seed collectors can, under the drive of the swing drive mechanism provided in the planting assembly, collect, store, and plant wheat seeds located in the seed storage cavity.

[0041] The wheat seeder in this embodiment includes a seeding assembly and the aforementioned seed picker for the wheat seeder. When using the wheat seeder in this embodiment to sow wheat seeds, it helps to reduce the resistance between the radial outer surface of the body and the wheat seeds stored in the seed storage cavity, and facilitates the movement of the wheat seeds stored in the seed storage cavity towards the seed picker and into the seed picker. Furthermore, it helps to make the volume of the seed picker suitable, so that each seed picker can provide suitable and sufficient space to accommodate a certain number of wheat seeds, improving the reliability and stability of each seed picker in sowing wheat seeds. Furthermore, it helps to improve the applicability of the seed picker to sowing various single-grain wheat seeds, thereby improving the reliability and stability of the wheat seeder in sowing wheat seeds.

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0053] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0054] 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 scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0055] One aspect of this application provides a seed-collecting structure for a wheat seeder, such as... Figures 1 to 3 As shown, it includes:

[0056] The main body 2 has an arc-shaped surface on its radial outer side. Several seed-collecting pits 201 are provided on the arc-shaped surface for collecting wheat seeds and are concave relative to the arc-shaped surface. The end of the seed-collecting pit 201 facing the radial outer side of the main body 2 is open to form a seed passage for the wheat seeds to pass through. The number of wheat seeds that the seed-collecting pit 201 can hold is N, and the volume of the seed-collecting pit 201 is M*N, where M is in the range of 56.00≤M≤73.00, and N is a positive integer from 1 to 6. The unit of volume is mm³.

[0057] In this embodiment, as Figures 1 to 3 As shown, in this embodiment, the outer radial side of the main body 2 has an arc-shaped surface, and the seed-collecting hole 201 is disposed on the arc-shaped surface. During the seed-collecting process by the main body 2 swinging, this helps reduce the resistance between the outer radial side of the main body 2 and the wheat seeds stored in the seed storage cavity, and facilitates the movement of the wheat seeds stored in the seed storage cavity towards the seed-collecting hole 201 and their falling into the seed-collecting hole 201. Furthermore, in this embodiment, the volume of the seed-collecting hole 201 is M*N, where N is the number of wheat seeds that the seed-collecting hole 201 can hold, and M is in the range of 56.00 ≤ M. A value ≤73.00 is beneficial for ensuring that the volume of the seed collection hole 201 is suitable, so that each seed collection hole 201 can provide a suitable and sufficient space to accommodate a certain number of wheat seeds, thereby improving the reliability and stability of seed collection in each seed collection hole 201. Furthermore, the range of M can cover the volume range of various single wheat seeds, which is beneficial for improving the applicability of the seed collection hole 201 to seed collection of various single wheat seeds. Therefore, using the seed collection structure in this embodiment as the seed collection component in the seed collector is beneficial for improving the reliability and stability of seed collection in the seed collector.

[0058] In this embodiment, when the number of wheat seeds that the seed collection hole 201 needs to hold is two, and the value of M is 66.00, then the volume of the seed collection hole 201 is 66.00*2=132.00mm³. Furthermore, the number of wheat seeds that each seed collection hole 201 needs to hold can be determined according to the sowing quantity requirements. Furthermore, the specific data of M can be set according to a certain wheat seed variety being sown, thereby improving the applicability of the seed collection hole 201 to that wheat seed variety. In addition, the specific data of M can also be set according to multiple wheat seed varieties, so that the seed collection hole 201 can be applicable to multiple wheat seed varieties.

[0059] In this embodiment, as Figure 1 and Figure 2 As shown, the arc-shaped surface provided on the radial outer side of the body 2 is specifically an arc-shaped surface 20. The seed-taking hole 201 is provided on the arc-shaped surface 20 and is recessed towards the body 2. Specifically, in this embodiment, there are two seed-taking holes 201, and the two seed-taking holes 201 are arranged in the lower part of the arc-shaped surface 20.

[0060] In this embodiment, as Figure 4 and Figure 5 As shown, in this embodiment, the main body 2 is mounted on a support structure 1 to form a seed extractor. It should be noted that in this embodiment, the main body 2 can be mounted on the support structure 1 by means of a connector or a connecting structure. The main body 2 can also be mounted on the support structure 1 by means of adhesive. In short, there are many ways to mount the main body 2 on the support structure 1. In addition, the support structure 1 can also have many structures. The support structure 1 shown in this embodiment is only one of many structures.

[0061] Furthermore, such as Figures 4 to 9 As shown in the figure, the support structure 1 in this embodiment includes a swing drive connecting block 10, a first mounting support protrusion 11, and a second mounting support protrusion 12. The swing drive connecting block 10 has a connecting through groove 101 for connecting with the swing drive mechanism in the length direction. The first mounting support protrusion 11 is connected to one side of the swing drive connecting block 10 and extends radially relative to the first mounting support protrusion 11. The second mounting support protrusion 12 is connected to one side of the swing drive connecting block 10 and extends radially relative to the first mounting support protrusion 11. The second mounting support protrusion 12 is located on one side of the first mounting support protrusion 11, and a mounting limiting groove is defined between the first mounting support protrusion 11 and the second mounting support protrusion 12. The body 2 can be installed in the mounting limiting groove. In addition, the support structure 1 in this embodiment can also be designed as other suitable structures.

[0062] In one embodiment of this application, M is in the range of 60.00≤M≤70.00.

[0063] In this embodiment, the range of M is 60.00≤M≤70.00. The numerical range of M is closer to the volume range of a single wheat seed, which is beneficial for providing suitable and sufficient space for a certain number of wheat seeds in each seed collection hole 201. Furthermore, the range of M can cover the volume range of multiple single wheat seeds, which is beneficial for improving the applicability of the seed collection hole 201 to collecting multiple single wheat seeds.

[0064] In one embodiment of this application, when the wheat seed variety is Xindong 52, the range of M is 63.00≤M≤73.00;

[0065] When the wheat seed variety is Xindong 22 or Xinchun 38, the range of M is 56.00≤M≤66.00;

[0066] When the wheat seed variety is Xinchun 38 and sown in spring, the range of M is 59.00≤M≤69.00.

[0067] In this embodiment, when the wheat seed variety is Xindong 52, the range of M is 63.00≤M≤73.00. This range of M values ​​is closer to the volume range of a single wheat seed of the Xindong 52 variety, which is beneficial because each seed collection hole 201 can provide suitable and sufficient space to accommodate a certain number of Xindong 52 wheat seeds. Similarly, when the wheat seed variety is Xindong 22 or Xinchun 38, the range of M is 56.00≤M≤66.00, and this range of M values ​​is closer to that of the Xindong 22 or Xinchun 38 varieties. The volume range of a single wheat seed in the egg-coated variety ensures that each seed collection hole 201 can provide suitable and sufficient space to accommodate a certain number of wheat seeds of the Xin Dong 22 or Xin Chun 38 egg-coated variety. Similarly, when the wheat seed variety is Xin Chun 38 spring-sown, the range of M is 59.00≤M≤69.00. The value range of M is closer to the volume range of a single wheat seed of the Xin Chun 38 spring-sown variety, which ensures that each seed collection hole 201 can provide suitable and sufficient space to accommodate a certain number of wheat seeds of the Xin Chun 38 spring-sown variety.

[0068] In this embodiment, taking wheat seed of variety Xindong 52 as an example, when the number of wheat seeds that the seed collection hole 201 needs to hold is three and the value of M is 68.00, then the volume of the seed collection hole 201 is 68.00*3=204.00mm³. In addition, for other varieties of wheat seeds, the volume of the seed collection hole 201 can also be determined by the above method, which will not be elaborated here.

[0069] It should be noted that the "volume range of a single wheat seed" mentioned above refers to the normal volume range of a single wheat seed; in addition, the wheat seeds used for sowing are preferably seeds obtained through screening, in which obviously deformed or damaged seeds are removed during the screening process.

[0070] One embodiment of this application, such as Figure 1 and Figure 2 As shown, there are two seed-taking holes 201, which are spaced apart along the length of the body 2.

[0071] In this embodiment, as Figure 1 and Figure 2 As shown, in this embodiment, there are two seed-collecting holes 201, which makes the structure of the main body 2 simple, facilitates the production of the main body 2, and helps to reduce the production cost of the main body 2. In addition, the presence of two seed-collecting holes 201 allows for simultaneous seed collection in the seed-collecting area, which helps to increase the amount of seeds collected each time, thereby helping to meet the requirements for wheat seed input.

[0072] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the two seed-collecting holes 201 are arranged at intervals along the length direction of the body 2, and the centers of the two seed-collecting holes 201 along the length direction of the body 2 are located on the same straight line; in addition, the number of seed-collecting holes 201 in this embodiment can also be one, three or four, etc., as needed.

[0073] One embodiment of this application, such as Figures 1 to 3 As shown, the main body 2 is also provided with an inclined surface 21 and an inclined surface 22. The inclined surface 21 and the inclined surface 22 are set at an angle. The two ends of the arc-shaped surface in the circumferential direction are connected to the inclined surface 21 and the inclined surface 22 respectively. The main body 2 is also provided with a snap-fit ​​protrusion for snap-fitting. The snap-fit ​​protrusion is connected to one of the inclined surface 21 and the inclined surface 22.

[0074] In this embodiment, as Figure 2 and Figure 3 As shown, in this embodiment, by connecting a snap-fit ​​protrusion to one of the inclined surfaces 21 and 22, it is convenient to design the seed extractor as a split structure and to include the main body 2 as part of the seed extractor. This facilitates the connection of the main body 2 with other parts of the seed extractor through the snap-fit ​​protrusion to form the seed extractor. In addition, including the main body 2 as part of the seed extractor makes it easier to produce the main body 2 and then snap the snap-fit ​​protrusion into the slots provided on other parts of the seed extractor to connect the produced main body 2 with other parts of the seed extractor to form the seed extractor. This helps to reduce the difficulty of producing and processing the seed extractor and reduce the production cost of the seed extractor.

[0075] In this embodiment, as Figure 2 and Figure 3 As shown, in this embodiment, the snap-fit ​​protrusion is connected to the inclined surface 21 and extends downward. Specifically, the snap-fit ​​protrusion connected to the inclined surface 21 is snap-fit ​​protrusion 211, which extends downward at an inclination. In addition, in this embodiment, the mounting support protrusion 11 of the support structure 1 has a snap-fit ​​groove 112 opposite to the snap-fit ​​protrusion 211. The snap-fit ​​groove 112 is inclined and extends downward through the mounting support protrusion 111, and the snap-fit ​​protrusion 211 can snap into the snap-fit ​​groove 112.

[0076] Furthermore, such as Figures 1 to 3 As shown, in this embodiment, the included angle between the inclined surface 21 and the inclined surface 22 is an obtuse angle, and the end faces of the left and right ends of the body 2 are both vertical planes, which is beneficial for the processing and forming of the body 2. In particular, when the body 2 is injection molded by injection molding process, it is beneficial for demolding the body 2 formed by injection molding process.

[0077] One embodiment of this application, such as Figures 1 to 3 As shown, the main body 2 is also provided with a snap-fit ​​groove 203 for snap-fitting, which is provided on the other surface of the inclined surface 21 and the inclined surface 22.

[0078] In this embodiment, as Figures 1 to 3 As shown, in this embodiment, by connecting a snap-fit ​​groove 203 to another surface of inclined surface 21 and inclined surface 22, it is convenient to design the seed extractor as a split structure and to include the main body 2 as part of the seed extractor. This facilitates the connection of the main body 2 with other parts of the seed extractor through the snap-fit ​​groove 203 to form the seed extractor. In addition, including the main body 2 as part of the seed extractor makes it easier to produce the main body 2 and then snap the protrusions on other parts of the seed extractor into the snap-fit ​​groove 203, thereby connecting the produced main body 2 with other parts of the seed extractor to form the seed extractor. This helps to reduce the production and processing difficulty of the seed extractor and reduce the production cost of the seed extractor.

[0079] In this embodiment, as Figures 1 to 3 As shown, in this embodiment, the snap-fit ​​groove 203 is provided on the inclined surface 22. Specifically, in this embodiment, there is one snap-fit ​​groove 203, which is provided on the upper part of the inclined surface 22 and extends out of the upper part of the arc-shaped surface. Alternatively, the snap-fit ​​groove 203 can also be provided at other positions on the inclined surface 22, so that the main body 2 can be connected to other parts constituting the seed extractor through the snap-fit ​​groove 203 to form the seed extractor.

[0080] One embodiment of this application, such as Figure 1 and Figure 2As shown, the seed is round in shape through the opening, and the arc-shaped surface is rounded.

[0081] In this embodiment, as Figure 1 and Figure 2 As shown, in this embodiment, the seed passage opening is circular, which facilitates the falling of wheat seeds into the seed-collecting hole 201 when they approach the seed passage opening, improving the smoothness of seed collection by the seed-collecting hole 201. Furthermore, the arc-shaped surface further reduces the resistance between the radially outer surface of the body 2 and the wheat seeds stored in the seed storage cavity during the seed-collecting process by oscillation. Furthermore, in this embodiment, the seed passage opening can also be configured to be approximately circular, and the arc-shaped surface can also be configured to be approximately arc-shaped.

[0082] In one embodiment of this application, the seed-harvesting hole 201 has a semi-elliptical cavity structure or a semi-pebble cavity structure.

[0083] In this embodiment, the seed-collecting cavity 201 has a semi-elliptical cavity structure or a semi-pebble cavity structure. This increases the matching degree between the inner wall contour of the seed-collecting cavity 201 and the outer contour of the wheat seed, which is beneficial for the seed-collecting cavity 201 to collect the wheat seed. In addition, it makes the inner wall of the seed-collecting cavity 201 smooth, which is beneficial for the wheat seed to be smoothly released from the seed-collecting cavity 201 when it is sown in the sowing area. It should be noted that the seed-collecting cavity 201 with a semi-elliptical cavity structure or a semi-pebble cavity structure is not illustrated in this embodiment.

[0084] One embodiment of this application, such as Figure 1 and Figure 2 As shown, the seed-taking cavity 201 has a frustum-shaped cavity structure. The end of the seed-taking cavity 201 closer to the seed passage is the large-diameter end, and the end of the seed-taking cavity 201 farther away from the seed passage is the small-diameter end.

[0085] In this embodiment, as Figure 1 and Figure 2 As shown, the seed-collecting cavity 201 in this embodiment has a frustum-shaped cavity structure. The end of the seed-collecting cavity 201 near the seed passage is the larger diameter end, which is beneficial for wheat seeds in the seed storage cavity to fall into the seed-collecting cavity 201 when they approach the seed passage, thus improving the smoothness of the seed-collecting cavity 201 in collecting wheat seeds. In addition, it makes the inner sidewall of the seed-collecting cavity 201 smooth, which is beneficial for the wheat seeds to be smoothly thrown out of the seed-collecting cavity 201 when the seed-collecting cavity 201 is used to collect wheat seeds in the seed-collecting area.

[0086] One embodiment of this application, such as Figure 1 and Figure 2As shown, the bottom of the seed-taking hole 201 has a hemispherical concave structure, and the center of the circle corresponding to the bottom of the seed-taking hole 201 coincides with the center of the circle corresponding to the small diameter end.

[0087] In this embodiment, as Figure 1 and Figure 2 As shown, the bottom of the seed-collecting hole 201 in this embodiment has a hemispherical concave structure, which is beneficial to increase the depth of the seed-collecting hole 201 and thus increase the volume of the seed-collecting hole 201; furthermore, the center of the circle corresponding to the bottom of the seed-collecting hole 201 coincides with the center of the circle corresponding to the small diameter end, which facilitates the uniform distribution of wheat seeds falling into the seed-collecting hole 201.

[0088] One embodiment of this application, such as Figures 1 to 3 As shown, a number of injection molding process grooves 202 are also provided on the arc surface. The injection molding process grooves 202 are concave relative to the arc surface and are located on one side of the seed-taking hole 201. The body 2 is injection molded by injection molding process.

[0089] In this embodiment, as Figures 1 to 3 As shown, in this embodiment, several injection molding process grooves 202 are also provided on the arc-shaped surface. During the injection molding process of the body 2, the protruding limiting block located at the injection molding process groove 202 can be used as the positioning part for the body 2 molding, which is beneficial for the body 2 to be injection molded. In addition, when the body 2 is injection molded, the position inside the injection molding process groove 202 is the protruding limiting block. The protruding limiting block is adhered to the body 2. The adhesion relationship between the protruding limiting block and the body 2 can be used to demold the injection molded body 2, thereby improving the convenience of demolding the injection molded body 2.

[0090] In this embodiment, as Figures 1 to 3 As shown, the radially outer arc-shaped surface of the body 2 is specifically an arc-shaped surface four 20. The injection molding process groove 202 is disposed on the arc-shaped surface four 20. In this embodiment, there are two injection molding process grooves 202, which are specifically disposed on the upper part of the arc-shaped surface four 20 and located on both sides of the snap-fit ​​groove 203 in the left and right directions. Furthermore, the injection molding process groove 202 extends backward in the front-back direction, and the rear end of the injection molding process groove 202 protrudes through the inclined surface two 22. In addition, the injection molding process groove 202 in this embodiment can also be disposed at other positions on the arc-shaped surface four 20, and the shape and structure of the injection molding process groove 202 can also have various forms.

[0091] Furthermore, the body 2 in this embodiment is injection molded using an injection molding process. Based on the structure of the body 2 disclosed in this application, a suitable injection molding mold can be designed according to the structure of the body 2 to injection mold the body 2 in this embodiment. In addition, the specific injection molding process can refer to the process in the prior art. The injection molding mold and injection molding process are not the focus of this application and will not be described in detail here.

[0092] Another aspect of this application provides a seed picker for a wheat seeder, such as... Figure 4 and Figure 5 As shown, it includes:

[0093] Support structure 1;

[0094] The seed-collecting structure for the wheat seeder described above has its main body 2 detachably mounted on the support structure 1.

[0095] In this embodiment, as Figure 4 and Figure 5 As shown, the seed extractor for a wheat planter in this embodiment includes a support structure 1 and the aforementioned seed extractor structure. This design helps reduce the resistance between the radially outer surface of the body 2 and the wheat seeds stored in the seed storage cavity, and facilitates the movement of the wheat seeds stored in the seed storage cavity towards the seed extractor 201 and their entry into the seed extractor 201. Furthermore, it allows for a suitable volume of the seed extractor 201, ensuring that each seed extractor 201 provides adequate space for a certain number of wheat seeds, thereby improving the reliability and stability of seed extraction by each seed extractor 201. Furthermore, it enhances the applicability of the seed extractor 201 to extract various single-grain wheat seeds, further improving the reliability and stability of the seed extractor. Moreover, the detachable mounting of the body 2 onto the support structure 1 allows for the separate production of the support structure 1 and the seed extractor structure, which are then mounted on the support structure 1 to form the seed extractor. This reduces the production cost of the seed extractor and facilitates maintenance and replacement of the seed extractor structure.

[0096] In this embodiment, as Figure 4 and Figure 5As shown, the support structure 1 in this embodiment includes a swing drive connecting block 10, a first mounting support protrusion 11, and a second mounting support protrusion 12.

When the connecting slot 101 has a square slot structure, the corresponding swing drive shaft is designed to have a cubic structure so that the swing drive shaft can be adapted to be inserted into the connecting slot 101 and drive the swing drive connecting block 10 to swing. Furthermore, the connecting slot 101 in this embodiment can also be designed into other suitable shapes. It should be noted that the swing drive shaft is not illustrated in this embodiment.

[0100] One embodiment of this application, such as Figures 4 to 6 , Figure 8 As shown, the first torsion spring mounting slot includes:

[0101] The first torsion spring body storage part 102 is used to store the body 2 part of the first torsion spring. The first torsion spring body storage part 102 extends outward from the connecting through groove 101 with the connecting through groove 101 as the center.

[0102] The first torsion spring connecting arm storage part 103 is used to store one connecting arm of the first torsion spring. The first torsion spring connecting arm storage part 103 is located on one circumferential side of the first torsion spring body storage part 102. One end of the first torsion spring body storage part 102 is connected to the first torsion spring mounting groove, and the other end of the first torsion spring body storage part 102 extends outward to the mounting support protrusion 12.

[0103] The second torsion spring mounting slot includes:

[0104] The second torsion spring body storage part 105 is used to store the body 2 part of the second torsion spring. The second torsion spring body storage part 105 extends outward from the connecting through groove 101 with the connecting through groove 101 as the center.

[0105] The second torsion spring connecting arm storage part 106 is used to store one connecting arm of the second torsion spring.

One end of the second torsion spring body storage part 105 is connected to the second torsion spring mounting groove, and the other end of the second torsion spring body storage part 105 extends outward to the mounting support protrusion 12.

[0106] In this embodiment, as Figures 4 to 6 , Figure 8 As shown, in this embodiment, the first torsion spring body housing portion 102 has a hollow cylindrical structure, which facilitates the housing of the first torsion spring body portion 2. Furthermore, the second torsion spring body housing portion 105 has a hollow cylindrical structure, which facilitates the housing of the second torsion spring body portion 2. In addition, the two ends of the swing drive shaft inserted into the connecting slot 101 pass through the middle of the first torsion spring body portion 2 and the second torsion spring body portion 2, respectively, and the first torsion spring body portion 2 and the second torsion spring body portion 2 are sleeved on the outer periphery of the swing drive shaft. It should be noted that the first torsion spring, the second torsion spring and the swing drive shaft are not illustrated in this embodiment. The structure of the swing drive shaft and the swing drive mechanism can also refer to the prior art, and will not be described in detail here. Furthermore, the specific installation method of the first torsion spring and the second torsion spring can also refer to the prior art, and will not be described in detail here.

[0107] One embodiment of this application, such as Figures 4 to 6 , Figure 8 As shown, the second torsion spring connecting arm storage part 106 is arranged opposite to the first torsion spring connecting arm storage part 103. The mounting support protrusion 12 is provided with a locking groove 124 along the length direction of the swing drive connecting block 10. The two ends of the locking groove 124 are respectively connected to the first torsion spring body storage part 102 and the second torsion spring body storage part 105.

[0108] Furthermore, such as Figure 8 and Figure 9 As shown, the snap-fit ​​slot 124 in this embodiment has a strip-shaped structure. The snap-fit ​​slot 124 can also be set to other shapes to facilitate the insertion of one connecting arm of the first torsion spring and one connecting arm of the second torsion spring.

[0109] One embodiment of this application, such as Figures 4 to 9 As shown, the first mounting support protrusion 11 is provided with a first mounting part for mounting the seed-taking structure, and the second mounting support protrusion 12 is provided with a second mounting part for mounting the seed-taking structure. The seed-taking structure can be installed between the first mounting part and the second mounting part and is confined within the mounting limiting groove.

[0110] In this embodiment, as Figures 4 to 9 As shown, the upper side of the mounting support protrusion 11 forms a mounting support surface 111, and the front side of the mounting support protrusion 12 forms a mounting support surface 121. A mounting limiting groove is defined between the mounting support surface 111 and the mounting support surface 121. Furthermore, in this embodiment, the included angle between the mounting support surface 111 and the mounting support surface 121 is an obtuse angle, and the included angle between the inclined surface 21 and the inclined surface 22 in this embodiment is equal to the angle between the mounting support surface 111 and the mounting support surface 121.

[0111] In this embodiment, as Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, in this embodiment, the first mounting part is specifically a snap-fit ​​groove 112. The snap-fit ​​groove 112 is inclinedly disposed on the mounting support surface 111 and passes downward through the mounting support protrusion 111. The mounting support protrusion 111 is snapped into the snap-fit ​​groove 112. Further, in this embodiment, the second mounting part is specifically a snap-fit ​​protrusion 122. The snap-fit ​​protrusion 122 is connected to the mounting support surface 121 and extends forward. The snap-fit ​​protrusion 122 is approximately an annular protrusion. The upper side of the snap-fit ​​protrusion 122 is an arc-shaped convex surface, and the lower side of the snap-fit ​​protrusion 122 is approximately an arc-shaped concave surface. The front part of the lower side of the snap-fit ​​protrusion 122 is provided with a downwardly protruding arc-shaped limiting protrusion 1. 221, the arc-shaped limiting protrusion 1221 is arc-shaped. Correspondingly, the locking groove 203 in this embodiment is provided with a locking limiting protrusion 2031. The locking limiting protrusion 2031 protrudes relative to the bottom side wall of the locking groove 203. The front side wall of the locking limiting protrusion 2031 and the bottom side wall of the locking groove 203 define an arc-shaped recessed groove that is adapted to the arc-shaped limiting protrusion 1221. When the locking protrusion 122 is locked in the locking groove 203, the arc-shaped limiting protrusion 1221 extends into the arc-shaped recessed groove and limits the locking protrusion 122 in the front-back direction, thereby improving the reliability and fixation of the locking protrusion 122 and the locking groove 203.

[0112] One embodiment of this application, such as Figures 4 to 6 As shown, the side of the swing drive connecting block 10 facing away from the mounting limit groove forms an arc-shaped surface 104, the end of the mounting support protrusion 11 away from the swing drive connecting block 10 forms an arc-shaped surface 113, and the end of the mounting support protrusion 12 away from the swing drive connecting block 10 forms an arc-shaped surface 123.

[0113] One embodiment of this application, such as Figure 3 and Figure 5 As shown, in this embodiment, the snap-fit ​​protrusion on the main body 2 is connected to the inclined surface 21 and extends downward. Specifically, the snap-fit ​​protrusion connected to the inclined surface 21 is snap-fit ​​protrusion 211, which extends downward at an inclination. In addition, in this embodiment, the mounting support protrusion 11 of the support structure 1 has a snap-fit ​​groove 112 opposite to the snap-fit ​​protrusion 211. The snap-fit ​​groove 112 is inclined and passes downward through the mounting support protrusion 111, and the snap-fit ​​protrusion 211 can snap into the snap-fit ​​groove 112. Furthermore, in this embodiment, the rear end face of the second snap-fit ​​protrusion 211 is flush with the first inclined surface 21. When the body 2 is installed in the mounting limiting groove, the first inclined surface 21 fits against the first mounting support surface 111, and the second inclined surface 22 fits against the second mounting support surface 121. The second snap-fit ​​protrusion 211 of the body 2 engages with the snap-fit ​​groove 112 on the support structure 1, and the first snap-fit ​​protrusion 122 on the support structure 1 engages with the snap-fit ​​groove 203 of the body 2, thereby installing and limiting the body 2 on the support structure 1.

[0114] Furthermore, such as Figure 4 As shown, in this embodiment, the arc-shaped surface 213, arc-shaped surface 3123 and arc-shaped surface 420 are all arc-shaped structures. After the main body 2 is installed on the support structure 1, the arc surfaces of the arc-shaped surface 213, arc-shaped surface 3123 and arc-shaped surface 420 smoothly transition to form the arc contact surface of the seed extractor. This helps to reduce the resistance between the arc contact surface of the main body 2 and the wheat seeds stored in the seed storage cavity, and facilitates the movement of the wheat seeds stored in the seed storage cavity towards the seed extraction hole 201 and into the seed extraction hole 201.

[0118] In this embodiment, the wheat seeder includes a seeding assembly and the aforementioned seed picker for the wheat seeder. When using the wheat seeder in this embodiment to sow wheat seeds, it helps to reduce the resistance between the radial outer surface of the body 2 and the wheat seeds stored in the seed storage cavity, and facilitates the movement of the wheat seeds stored in the seed storage cavity towards the seed picker 201 and into the seed picker 201. Furthermore, it helps to make the volume of the seed picker 201 suitable, so that each seed picker 201 can provide suitable and sufficient space to accommodate a certain number of wheat seeds, improving the reliability and stability of each seed picker 201 in picking wheat seeds. Furthermore, it helps to improve the applicability of the seed picker 201 to picking various single-grain wheat seeds, thereby improving the reliability and stability of the wheat seeder in sowing wheat seeds.
