Description

Technical Field

[0001] This utility model relates to the field of seeding machinery and equipment technology, and in particular to a support structure and seed picker 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] Furthermore, in order to reduce the production cost of seed extractors, existing technologies design seed extractors that include a support structure and a seed-collecting structure, with the seed-collecting structure mounted on the support structure to obtain the seed extractor. However, the structural design of the support structure in existing seed extractors has defects, making it inconvenient to mount the seed-collecting structure on the support structure, and the reliability and stability of the seed-collecting structure mounted on the support structure need to be improved. Therefore, there is an urgent need for a support structure that can improve the reliability and stability of the seed-collecting structure mounted on the support structure. 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 support structure for a wheat seeder that is conducive to improving the reliability and stability of the seed-taking structure installed on the support structure; in addition, a seed taker for a wheat seeder and a wheat seeder are also provided.

[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 support structure for a wheat seeder is provided, comprising:

[0009] A swing drive connecting block, wherein the swing drive connecting block is provided with a connecting through groove in the length direction for connecting with a swing drive mechanism;

[0010] Mounting support protrusion one is connected to one side of the swing drive connecting block and extends radially relative to the mounting support protrusion one;

[0011] The second mounting support protrusion is connected to one side of the swing drive connecting block and extends radially relative to the first mounting support protrusion. The second mounting support protrusion is located on one side of the first mounting support protrusion, and the first mounting support protrusion and the second mounting support protrusion define a mounting limiting groove for mounting a seed-taking structure capable of taking wheat seeds.

[0012] The beneficial effects of this utility model are as follows: In this embodiment, the swing drive connecting block is provided with a connecting slot in the length direction for connecting with the swing drive mechanism, which facilitates the insertion of the swing drive mechanism into the connecting slot to connect the swing drive connecting block and the swing drive mechanism, and facilitates the swing drive connecting block to swing through the swing drive mechanism; In addition, the mounting support protrusion one and the mounting support protrusion two define a mounting limiting groove for mounting a seed-taking structure capable of taking wheat seeds, which facilitates the installation of the seed-taking structure in the limiting groove, and the mounting support protrusion one and the mounting support protrusion two support and limit the seed-taking structure installed in the mounting limiting groove, thereby improving the reliability and stability of the seed-taking structure installed on the support structure, and also facilitating the swinging of the seed-taking structure installed on the support structure through the swing drive connecting block to achieve seed taking.

[0013] 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.

[0015] In this embodiment, a first torsion spring mounting groove is provided on the first end face of the swing drive connecting block along the length direction, which facilitates the installation of the first torsion spring in the first torsion spring mounting groove. When the swing drive mechanism is disengaged from the swing drive of the swing drive connecting block, the swing drive connecting block can be driven to rotate in the opposite direction by the torque generated by the elastic deformation of the first torsion spring. Thus, the swing drive mechanism can cooperate with the first torsion spring to switch the seed-taking structure between the seed-taking position and the seed-planting position, thereby realizing the seed-taking structure to perform seed-taking and seed-planting operations on wheat seeds.

[0016] According to one embodiment of this application, a second torsion spring mounting groove for mounting a second torsion spring is provided on the second end face of the swing drive connecting block in the length direction.

This facilitates the installation of the second torsion spring in the second torsion spring mounting groove. When the swing drive mechanism disengages from the swing drive of the swing drive connecting block, the swing drive connecting block can be driven to rotate in the opposite direction by the torque generated by the elastic deformation of the first and second torsion springs. Thus, the swing drive mechanism, in conjunction with the first and second torsion springs, allows the seed-taking structure to switch between the seed-taking position and the seed-planting position, enabling the seed-taking structure to perform seed-taking and seed-planting operations on wheat seeds. In addition, the torque generated by the elastic deformation of the first and second torsion springs to drive the swing drive connecting block to rotate in the opposite direction provides more sufficient and stable torque, thereby improving the reliability and stability of the seed-taking structure in switching between the seed-taking position and the seed-planting position, which is beneficial to improving the reliability and stability of the seed-taking structure in taking wheat seeds.

One end of the second torsion spring body storage part is connected to the second torsion spring mounting groove, and the other end of the second torsion spring body storage part extends outward to the mounting support protrusion 2.

[0024] In this embodiment, by providing a first torsion spring body storage portion and a first torsion spring connecting arm storage portion, it is convenient to store the body portion of the first torsion spring in the first torsion spring body storage portion, and it is also convenient to store one connecting arm of the first torsion spring in the first torsion spring connecting arm storage portion. This facilitates the installation and storage of the first torsion spring in the first torsion spring mounting slot, and helps to avoid interference between the first torsion spring body and one connecting arm of the first torsion spring and other components. Similarly, in this embodiment, by providing a second torsion spring body storage portion and a second torsion spring connecting arm storage portion, it is convenient to store the body portion of the second torsion spring in the second torsion spring body storage portion, and it is also convenient to store one connecting arm of the second torsion spring in the second torsion spring connecting arm storage portion. This facilitates the installation and storage of the second torsion spring in the second torsion spring mounting slot, and helps to avoid interference between the second torsion spring body and one connecting arm of the second torsion spring and other components.

[0025] According to one embodiment of this application, the second torsion spring connecting arm storage part is disposed opposite to the first torsion spring connecting arm storage part, and the second mounting support protrusion is provided with a snap-fit ​​groove along the length direction of the swing drive connecting block. The two ends of the snap-fit ​​groove are respectively connected to the first torsion spring body storage part and the second torsion spring body storage part.

[0026] In this embodiment, the two ends of the snap-fit ​​groove are respectively connected to the first torsion spring body receiving part and the second torsion spring body receiving part, which is beneficial to snapping one connecting arm of the first torsion spring and one connecting arm of the second torsion spring into the snap-fit ​​groove, and to improving the stability of snapping and limiting one connecting arm of the first torsion spring and one connecting arm of the second torsion spring.

[0027] According to one embodiment of this application, the swing drive connecting block, the first mounting support protrusion and the second mounting support protrusion are injection molded and connected as one unit by injection molding process.

[0028] In this embodiment, the swing drive connecting block, mounting support protrusion one, and mounting support protrusion two are injection molded using an injection molding process, which facilitates the production of the support structure, reduces the production cost of the support structure, and also facilitates the mass production of the support structure.

[0029] According to one embodiment of this application, the first mounting support protrusion is provided with a first mounting portion for mounting the seed-taking structure, and the second mounting support protrusion is provided with a second mounting portion for mounting the seed-taking structure.

[0030] In this embodiment, the first mounting support protrusion is provided with a first mounting part, and the second mounting support protrusion is provided with a second mounting part. This facilitates the installation of the seed-taking structure between the first mounting part and the second mounting part and confines it within the mounting limiting groove.

[0031] According to one embodiment of this application, the side of the swing drive connecting block facing away from the mounting limiting groove forms an arc-shaped surface.

[0032] In this embodiment, the side of the swing drive connecting block facing away from the mounting limit groove forms an arc-shaped surface. When the swing drive connecting block drives the seed-taking structure to swing to achieve seed taking, it helps to avoid interference between the outer side of the swing drive connecting block facing away from the mounting limit groove and other components of the seed taker, thereby improving the stability of the swing drive connecting block driving the seed-taking structure to swing to achieve seed taking.

[0033] According to one embodiment of this application, the end of the mounting support protrusion away from the swing drive connecting block forms an arc-shaped surface two, and the end of the mounting support protrusion away from the swing drive connecting block forms an arc-shaped surface three.

[0034] In this embodiment, the end of the mounting support protrusion 1 away from the swing drive connecting block forms an arc-shaped surface 2. During the swinging process of the mounting support protrusion 1, it helps to reduce the resistance between the outer surface of the mounting support protrusion 1 away from the swing drive connecting block and the wheat seeds stored in the seed storage cavity. In addition, the end of the mounting support protrusion 2 away from the swing drive connecting block forms an arc-shaped surface 3, which helps to reduce the resistance between the outer surface of the mounting support protrusion 2 away from the swing drive connecting block and the wheat seeds stored in the seed storage cavity. This further helps to reduce the resistance between the seed picker with the support structure in this embodiment and the wheat seeds stored in the seed storage cavity during the seed picking process.

[0035] According to another aspect of this application, a seed taker for a wheat seeder is provided, comprising:

[0036] The aforementioned support structure for wheat seeders;

[0037] The seed-collecting structure is installed within the mounting limiting groove. The outer radial side of the seed-collecting structure has an arc-shaped surface four. This arc-shaped surface four has several seed-collecting pits that are recessed relative to the arc-shaped surface four, used for collecting wheat seeds. One end of each seed-collecting pit facing the outer radial side of the seed-collecting structure 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. The volume of each seed-collecting pit is M*N, where M ranges from 56.00 ≤ M ≤ 73.00, and N is a positive integer from 1 to 6. The unit of volume is mm³.

[0038] The seed collector for a wheat planter in this embodiment includes a support structure and a seed-collecting structure. This facilitates the installation of the seed-collecting structure within the limiting groove. The seed-collecting structure is supported and limited within the limiting groove by two support protrusions, improving the reliability and stability of the seed-collecting structure mounted on the support structure. Furthermore, the seed-collecting structure has an arc-shaped surface four on its radially outer side, with a seed-collecting socket disposed on this surface. During the seed-collecting process, the oscillating motion of the seed-collecting structure reduces the resistance between its radially outer surface and the wheat seeds stored in the seed storage cavity, and facilitates storage within the seed storage cavity. The wheat seeds inside the cavity move close to the seed collection hole and fall into it. Furthermore, in this embodiment, the volume of the seed collection hole is M*N, where N is the number of wheat seeds the seed collection hole can hold, and M ranges from 56.00 ≤ M ≤ 73.00. This ensures that the volume of the seed collection hole is suitable, providing adequate 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 for improving the applicability of the seed collection hole to collecting various single wheat seeds.

[0039] According to one embodiment of this application, the range of M is 60.00≤M≤70.00.

[0040] 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.

[0041] 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;

[0042] When the wheat seed variety is Xindong 22 or Xinchun 38, the range of M is 56.00≤M≤66.00;

[0043] When the wheat seed variety is Xinchun 38 spring sowing, the range of M is 59.00≤M≤69.00.

[0044] 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.

[0046] In this embodiment, several injection molding process grooves are provided on the arc-shaped surface. During the injection molding process of the seed-taking structure, the protruding limiting block located at the injection molding process groove can be used as the positioning part for the seed-taking structure, which is beneficial for the seed-taking structure 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 seed-taking structure. The protruding limiting block is adhered to the seed-taking structure. The adhesion relationship between the protruding limiting block and the seed-taking structure can be used to demold the injection-molded seed-taking structure, thereby improving the convenience of demolding the injection-molded seed-taking structure.

[0047] According to another aspect of this application, a wheat seeder is provided, comprising:

[0048] A seeding assembly, wherein the seeding assembly is provided with a seed storage chamber for storing wheat seeds;

[0049] 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.

[0050] The wheat seeder in this embodiment includes a seeding assembly and the aforementioned seed collector, which helps improve the reliability and stability of the seed collection structure installed on the support structure. Furthermore, when using the wheat seeder in this embodiment to sow wheat seeds, it helps reduce the resistance between the radially outer surface of the seed collector 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 collection hole and their falling into the seed collection hole. Furthermore, it helps to ensure that the volume of the seed collection hole is suitable, providing adequate space for a certain number of wheat seeds in each seed collection hole, improving the reliability and stability of seed collection in each seed collection hole. Furthermore, it helps to improve the applicability of the seed collection hole to collecting various single-grain wheat seeds, thereby improving the reliability and stability of the wheat seeder in sowing wheat seeds.

[0078] In this embodiment, as Figure 1 , Figure 3 and Figure 4As shown, in this embodiment, the first torsion spring body housing portion 102 has a hollow cylindrical structure, which facilitates the housing of the body portion of the first torsion spring. Furthermore, the second torsion spring body housing portion 105 has a hollow cylindrical structure, which facilitates the housing of the body portion of the second torsion spring. Additionally, the two ends of the swing drive shaft, which is inserted into the connecting slot 101, pass through the middle of the body portions of the first and second torsion springs, respectively, and the body portions of the first and second torsion springs 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 be referenced from existing technologies and will not be described in detail here. Furthermore, the specific installation methods of the first and second torsion springs can also be referenced from existing technologies and will not be described in detail here either.

[0079] One embodiment of this application, such as Figure 1 , Figure 3 and Figure 4 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.

[0080] One embodiment of this application, such as Figure 1 , Figure 3 and Figure 4 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.

[0081] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the two ends of the snap-fit ​​groove 124 are respectively connected to the first torsion spring body receiving part 102 and the second torsion spring body receiving part 105, which is beneficial to snapping one connecting arm of the first torsion spring and one connecting arm of the second torsion spring into the snap-fit ​​groove 124, and to improving the stability of snapping and limiting one connecting arm of the first torsion spring and one connecting arm of the second torsion spring.

[0082] Furthermore, such as Figure 3 and Figure 4As 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.

[0083] One embodiment of this application, such as Figures 1 to 4 As shown, in this embodiment, the swing drive connecting block 10, the mounting support protrusion one 11 and the mounting support protrusion two 12 are injection molded and connected as one unit by injection molding process.

[0084] In this embodiment, as Figures 1 to 4 As shown, in this embodiment, the swing drive connecting block 10, the mounting support protrusion one 11 and the mounting support protrusion two 12 are injection molded by injection molding process, which facilitates the production of support structure 1, reduces the production cost of support structure 1, and also facilitates the mass production of support structure 1.

[0085] One embodiment of this application, such as Figures 1 to 4 As shown, the first mounting support protrusion 11 is provided with a first mounting part for mounting the seed-taking structure 2, and the second mounting support protrusion 12 is provided with a second mounting part for mounting the seed-taking structure 2. The seed-taking structure 2 can be installed between the first mounting part and the second mounting part and is confined within the mounting limiting groove.

[0086] In this embodiment, as Figures 1 to 4 As shown, in this embodiment, the first mounting support protrusion 11 is provided with a first mounting part, and the second mounting support protrusion 12 is provided with a second mounting part. This facilitates the installation of the seed-taking structure 2 between the first mounting part and the second mounting part and confining it within the mounting limiting groove. It also improves the reliability and stability of the seed-taking structure 2 installed within the mounting limiting groove by the first mounting part and the second mounting part.

[0087] In this embodiment, as Figures 1 to 4As 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.

[0088] One embodiment of this application, such as Figure 1 , Figure 3 and Figure 4 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.

[0089] One embodiment of this application, such as Figure 1 , Figures 3 to 6As shown, the seed-taking structure 2 is also provided with an inclined surface 21 and an inclined surface 22, which are set at an angle. The arc-shaped surface is connected to the inclined surface 21 and the inclined surface 22 at both ends in the circumferential direction, respectively. Furthermore, the seed-taking structure 2 in this embodiment is provided with a snap-fit ​​protrusion 2, which is connected to the inclined surface 21 and extends downward. In addition, the mounting support protrusion 11 of the support structure 1 in this embodiment has a snap-fit ​​groove 112 opposite to the snap-fit ​​protrusion 2. The snap-fit ​​groove 112 is inclined and passes downward through the mounting support protrusion 11. The second snap-fit ​​protrusion can snap into the snap-fit ​​groove 112. Furthermore, in this embodiment, the rear end face of the second snap-fit ​​protrusion is flush with the first inclined surface 21. When the seed-taking structure 2 is installed in the installation limiting groove, the first inclined surface 21 abuts against the first installation support surface 111, and the second inclined surface 22 abuts against the second installation support surface 121. The second snap-fit ​​protrusion of the seed-taking structure 2 snaps into the snap-fit ​​groove 112 on the support structure 1, and the first snap-fit ​​protrusion 122 on the support structure 1 snaps into the snap-fit ​​groove 203 of the seed-taking structure 2, thus installing and limiting the seed-taking structure 2 on the support structure 1. It should be noted that the second snap-fit ​​protrusion, which is connected to the first inclined surface 21 and extends downwards, is not illustrated in this embodiment.

[0090] In this embodiment, as Figure 1 , Figure 3 and Figure 4 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.

[0091] One embodiment of this application, such as Figure 1 , Figure 3 and Figure 4 As shown, the side of the swing drive connecting block 10 facing away from the mounting limit groove forms an arc-shaped surface 104.

[0092] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the side of the swing drive connecting block 10 facing away from the mounting limit groove forms an arc-shaped surface 104. When the swing drive connecting block 10 swings to achieve seed taking by driving the seed taking structure 2, it helps to avoid interference between the outer side of the swing drive connecting block 10 facing away from the mounting limit groove and other components of the seed taker, thereby improving the stability of the swing drive connecting block 10 driving the seed taking structure 2 to swing to achieve seed taking.

[0093] One embodiment of this application, such as Figures 1 to 4As shown, 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.

[0094] In this embodiment, as Figures 1 to 4 As shown, in this embodiment, the end of the mounting support protrusion 11 away from the swing drive connecting block 10 forms an arc-shaped surface 113. During the swinging process of the mounting support protrusion 11, it helps to reduce the resistance between the outer surface of the mounting support protrusion 11 away from the swing drive connecting block 10 and the wheat seeds stored in the seed storage cavity. In addition, the end of the mounting support protrusion 12 away from the swing drive connecting block 10 forms an arc-shaped surface 123. This helps to reduce the resistance between the outer surface of the mounting support protrusion 12 away from the swing drive connecting block 10 and the wheat seeds stored in the seed storage cavity, thereby improving the resistance between the seed picker with the support structure 1 in this embodiment and the wheat seeds stored in the seed storage cavity during the seed picking process.

[0095] Furthermore, such as Figure 5 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 seed-taking structure 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 taker. This helps to reduce the resistance between the arc contact surface of the seed-taking structure 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-taking hole 201 and into the seed-taking hole 201.

[0096] Another aspect of this application provides a seed picker for a wheat seeder, such as... Figure 5 and Figure 6 As shown, it includes:

[0097] The aforementioned support structure 1 for a wheat seeder;

[0098] The seed-collecting structure 2 is installed in the installation limiting groove. The outer radial side of the seed-collecting structure 2 is provided with an arc-shaped surface 20. The arc-shaped surface 20 is provided with several seed-collecting pits 201 for collecting wheat seeds and are concave relative to the arc-shaped surface 20. The end of the seed-collecting pit 201 facing the outer radial side of the seed-collecting structure 2 is open to form a seed passage for wheat seeds to pass through. The number of wheat seeds that the seed-collecting pit 201 can hold is N. 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.

[0099] In this embodiment, as Figure 5 and Figure 6As shown, the seed picker for a wheat planter in this embodiment includes a support structure 1 and a seed picking structure 2. This facilitates the installation of the seed picking structure 2 into the limiting groove. The seed picking structure 2 is supported and limited by the first installation support protrusion 11 and the second installation support protrusion 12, which improves the reliability and stability of the seed picking structure 2 installed on the support structure 1. Furthermore, the outer radial side of the seed picking structure 2 is provided with an arc-shaped surface 20, and a seed picking socket 201 is disposed on the arc-shaped surface 20. During the seed picking process by oscillation, this reduces the resistance between the outer radial side of the seed picking structure 2 and the wheat seeds stored in the seed storage cavity, and facilitates storage in the seed storage cavity. The wheat seeds inside the cavity move close to the seed collection hole 201 and fall into it. Furthermore, in this embodiment, the volume of the seed collection hole 201 is M*N, where N is the number of wheat seeds that the seed collection hole 201 can hold, and M ranges from 56.00 ≤ M ≤ 73.00. This ensures that the volume of the seed collection hole 201 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 improves the applicability of the seed collection hole 201 for collecting various single wheat seeds.

[0100] 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.

[0101] In this embodiment, as Figure 5 and Figure 6 As shown, the radially outer arc-shaped surface of the seed-taking structure 2 is specifically an arc-shaped surface 20, and the seed-taking hole 201 is disposed on the arc-shaped surface 20, with the seed-taking hole 201 recessed towards the seed-taking structure 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.

[0102] In this embodiment, as Figure 5 and Figure 6As shown, in this embodiment, a seed-collecting structure 2 is installed on a support structure 1 to form a seed collector. It should be noted that the seed-collecting structure 2 in this embodiment can be installed on the support structure 1 by means of a connector or a connecting structure. The seed-collecting structure 2 can also be installed on the support structure 1 by means of adhesive. In short, there are many ways to install the seed-collecting structure 2 on the support structure 1. In addition, the structure of the seed-collecting structure 2 can also be of many kinds. The seed-collecting structure 2 shown in this embodiment is only one of many structures.

[0103] Furthermore, such as Figure 5 and Figure 6 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 seed taking structure 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.

[0104] In this embodiment, as Figure 5 and Figure 6 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.

[0105] In one embodiment of this application, M is in the range of 60.00≤M≤70.00.

[0106] 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.

[0107] In one embodiment of this application, when the wheat seed variety is Xindong 52, the range of M is 63.00≤M≤73.00;

[0108] When the wheat seed variety is Xindong 22 or Xinchun 38, the range of M is 56.00≤M≤66.00;

[0109] When the wheat seed variety is Xinchun 38 spring sowing, the range of M is 59.00≤M≤69.00.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] One embodiment of this application, such as Figure 5 and Figure 6As shown, the arc-shaped surface 20 is also provided with several injection molding process grooves 202. The injection molding process grooves 202 are recessed relative to the arc-shaped surface 20 and are located on one side of the seed-taking hole 201. The seed-taking structure 2 is injection molded by injection molding process.

[0114] In this embodiment, as Figure 5 and Figure 6 As shown, in this embodiment, several injection molding process grooves 202 are also provided on the arc-shaped surface 20. During the injection molding process of the seed-taking structure 2, the protruding limiting block located at the injection molding process groove 202 can be used as the positioning part for the molding of the seed-taking structure 2, which is beneficial for the seed-taking structure 2 to be injection molded. In addition, during the injection molding process of the seed-taking structure 2, the position inside the injection molding process groove 202 is the protruding limiting block. The protruding limiting block is adhered to the seed-taking structure 2. The adhesion relationship between the protruding limiting block and the seed-taking structure 2 can be used to demold the injection-molded seed-taking structure 2, thereby improving the convenience of demolding the injection-molded seed-taking structure 2.

[0115] In this embodiment, as Figure 5 and Figure 6 As shown, the radially outer arc-shaped surface of the seed-taking structure 2 is specifically an arc-shaped surface 20. The injection molding process groove 202 is disposed on the arc-shaped surface 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 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 22. In addition, the injection molding process groove 202 in this embodiment can also be disposed at other positions on the arc-shaped surface 20, and the shape and structure of the injection molding process groove 202 can also have various forms.

[0116] Furthermore, the seed-taking structure 2 in this embodiment is injection molded using an injection molding process. Based on the structure of the seed-taking structure 2 disclosed in this application, a suitable injection molding mold can be designed according to the structure of the seed-taking structure 2 to injection mold the seed-taking structure 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.

[0117] One embodiment of this application, such as Figure 5 and Figure 6 As shown, there are two seed-taking holes 201, which are spaced apart along the length of the seed-taking structure 2.

[0118] In this embodiment, as Figure 5 and Figure 6 As shown, in this embodiment, there are two seed-collecting holes 201, which makes the structure of the seed-collecting structure 2 simple, facilitates the production of the seed-collecting structure 2, and helps to reduce the production cost of the seed-collecting structure 2. In addition, since there are two seed-collecting holes 201, seeds can be collected simultaneously in the seed-collecting area through the two seed-collecting holes 201, which helps to increase the amount of seeds collected each time, thereby helping to meet the requirements of wheat seed input.

[0119] Furthermore, such as Figure 5 and Figure 6 As shown, in this embodiment, the two seed-collecting holes 201 are arranged at intervals along the length direction of the seed-collecting structure 2, and the centers of the two seed-collecting holes 201 along the length direction of the seed-collecting structure 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.

[0120] One embodiment of this application, such as Figure 5 and Figure 6 As shown, the seed-taking structure 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 arc-shaped surface is connected to the inclined surface 21 and the inclined surface 22 at both ends in the circumferential direction, respectively. The seed-taking structure 2 is also provided with a snap-fit ​​protrusion for snapping. The snap-fit ​​protrusion is connected to one of the inclined surface 21 and the inclined surface 22.

[0121] In this embodiment, as Figure 5 and Figure 6 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 seed extractor structure 2 as part of the seed extractor. This facilitates the connection of the seed extractor structure 2 with other parts of the seed extractor through the snap-fit ​​protrusion to form the seed extractor. In addition, including the seed extractor structure 2 as part of the seed extractor makes it easier to produce the seed extractor structure 2. Then, the snap-fit ​​protrusion is snapped into the slot provided on other parts of the seed extractor to connect the produced seed extractor structure 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.

[0122] 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 the snap-fit ​​protrusion 2, which extends downward at an incline. In addition, the mounting support protrusion 11 of the support structure 1 in this embodiment has a snap-fit ​​groove 112 opposite to the snap-fit ​​protrusion 2. The snap-fit ​​groove 112 is inclined and extends downward through the mounting support protrusion 11, and the snap-fit ​​protrusion 2 can snap into the snap-fit ​​groove 112.

[0123] Furthermore, such as Figure 5and Figure 6 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 seed-taking structure 2 are both vertical planes, which is beneficial for the processing and molding of the seed-taking structure 2. In particular, when the seed-taking structure 2 is injection molded by injection molding process, it is beneficial for demolding the seed-taking structure 2 that has been injection molded by injection molding process.

[0124] One embodiment of this application, such as Figure 5 and Figure 6 As shown, the seed-taking structure 2 is also provided with a snap-fit ​​groove 203 for snap-fitting, which is located on the other surface of the inclined surface 21 and the inclined surface 22.

[0125] In this embodiment, as Figure 5 and Figure 6 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 seed extractor structure 2 as part of the seed extractor. This facilitates the connection of the seed extractor structure 2 with other parts of the seed extractor through the snap-fit ​​groove 203 to form the seed extractor. In addition, including the seed extractor structure 2 as part of the seed extractor facilitates the production of the seed extractor structure 2. Then, the protrusions provided on other parts of the seed extractor are snapped into the snap-fit ​​groove 203, realizing the connection of the produced seed extractor structure 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.

[0126] In this embodiment, as Figure 5 and Figure 6 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 seed-taking structure 2 can be connected to other parts constituting the seed taker through the snap-fit ​​groove 203 to form the seed taker.

[0127] One embodiment of this application, such as Figure 5 and Figure 6 As shown, the seed is round in shape through the opening, and the arc-shaped surface is rounded.

[0128] In this embodiment, as Figure 5 and Figure 6As 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 in the seed storage cavity, 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 seed-collecting structure 2 and the wheat seeds stored in the seed storage cavity during the oscillating process of seed collection. 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.

[0129] One embodiment of this application, such as Figure 5 and Figure 6 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.

[0130] In this embodiment, as Figure 5 and Figure 6 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.

[0131] One embodiment of this application, such as Figure 5 and Figure 6 As 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.

[0132] In this embodiment, the bottom of the seed-collecting hole 201 has a hemispherical concave structure, which helps to increase the depth of the seed-collecting hole 201 and thus increase its volume. 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 even distribution of wheat seeds falling into the seed-collecting hole 201.

[0133] In another aspect, this application provides a wheat seeder comprising:

[0134] The seeding assembly has a seed storage chamber for storing wheat seeds.

[0135] The seed picker described above for a wheat planter has multiple seed pickers installed at intervals around the circumference of the planter assembly. During the rolling process of the planter assembly, the seed pickers can pick up, store, and plant wheat seeds located in the seed storage chamber under the drive of the swing drive mechanism set in the planter assembly.

[0136] In this embodiment, the wheat seeder includes a seeding assembly and the aforementioned seed extractor, which improves the reliability and stability of the seed extractor structure 2 mounted on the support structure 1. Furthermore, when using the wheat seeder in this embodiment to sow wheat seeds, it reduces the resistance between the radially outer surface of the seed extractor 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 their entry into the seed extraction hole 201. Furthermore, it ensures that the volume of the seed extraction hole 201 is suitable, providing sufficient space for a certain number of wheat seeds in each seed extraction hole 201, thus improving the reliability and stability of seed extraction in each seed extraction hole 201. Furthermore, it enhances the applicability of the seed extraction hole 201 to extract various single-grain wheat seeds, thereby improving the reliability and stability of the wheat seeder in sowing wheat seeds.
