[0060] In order to further understand the content of the present application, the present application is described in detail in combination with the drawings and embodiments.

[0061] The structure, proportion, size, etc. shown in the drawings of the specification are only used to cooperate with the content disclosed in the specification, to be understood and read by those skilled in the art, and are not used to define the limiting conditions under which the present application can be implemented, so they do not have technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effect and purpose that the present application can produce, should still fall within the scope of the technical content disclosed by the present application. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and the like used in the specification are only for the convenience of clear description, and are not used to limit the scope of implementation, and the change or adjustment of the relative relationship is also considered as the implementation of the present application without substantial changes in technical content.

[0062] Different crops have different requirements for seeding spacing. For example, corn plants are relatively large in size and have wide leaves, which require a larger growth space to ensure ventilation and light transmission, and the appropriate seeding spacing is generally about 25-30 cm; while for densely planted crops such as wheat, the seeding spacing is usually 10-15 cm. The seeding machine with adjustable seeding spacing can easily adjust to the appropriate spacing when seeding different crops, meeting the diverse planting needs.

[0063] Different crop varieties and planting patterns have different requirements for single seeding quantity. For example, when planting wheat and other densely planted crops, a higher seeding quantity is required to ensure the basic seedling number per unit area. Generally, the wheat seeding quantity in high-yield fields is about 10-15 kg per mu. While for crops such as corn, which have relatively large plants, the seeding quantity per mu is generally 3-5 kg. The seeding machine with controllable single seeding quantity can accurately seed according to these requirements, adapting to diverse planting scenarios.

[0064] Precise seeding quantity is crucial for crop growth and development. For example, in vegetable planting, carrot seeds are very small, and their germination rate and growth are closely related to seeding density. If the seeding is too dense, it will cause competition for nutrients, water and light among seedlings, making the seedlings weak; if the seeding is too sparse, it will reduce land utilization. By controlling the single seeding quantity, the seeds can be sown in the soil at an appropriate density, such as 3-5 kg per square meter for carrot seeds, which is beneficial to the vigorous growth of vegetables.

[0065] Appropriate seeding quantity can ensure that crops are reasonably distributed on the land and make full use of land resources. For example, in soybean planting, soybean root system has nitrogen fixation effect, and appropriate planting density can make each soybean plant effectively utilize soil nutrients, while not causing excessive nutrient competition due to over-dense planting. If the single seeding quantity is too high, it will exceed the carrying capacity of the land, causing excessive consumption of soil nutrients; while if the seeding quantity is too low, the land resources will not be fully utilized.

[0066] The seeding machine of the present application comprises a frame and a seeding mechanism, a pushing mechanism, a fertilizing mechanism and a rotary driving mechanism mounted on the frame. The seeding mechanism is used for seeding, and the fertilizing mechanism is used for fertilizing. The first furrow opener 61 and the second furrow opener 62 are symmetrically arranged in front of the frame. The furrow opened by the first furrow opener 61 is used for seeding, and the furrow opened by the second furrow opener 62 is used for fertilizing, so as to avoid the direct contact between the seeds and the fertilizer and the occurrence of seedling burning.

[0067] Generally, the prior art seeds and fertilizes in the same furrow. If the adjustment of the fertilizer discharge amount has a problem, the fertilizer application amount in unit area is far more than the tolerance of the crop seed germination and the seedling growth in the initial stage, which will cause seedling burning. However, the present application can avoid the occurrence of seedling burning by arranging two furrow openers and controlling the distance between the furrow openers. More specifically, the distance between the first furrow opener 61 and the second furrow opener 62 is preferably about 20 cm.

[0068] The seeding mechanism comprises a first rotating shaft 10 and a seed discharge groove 11. The seed discharge groove 11 is sleeved on the first rotating shaft 10 and is fixedly connected with the first rotating shaft 10, and the two are synchronously rotated. More specifically, the seed discharge groove 11 is provided with a plurality of protruding portions 111 along the circumferential direction thereof, and a recessed portion 112 is formed between adjacent two protruding portions 111.

[0069] The seeding mechanism further comprises an adjusting assembly 12 which is interlocked with the seed discharge groove 11. The adjusting assembly 12 is sleeved on the first rotating shaft 10 and is connected with the pushing mechanism 20. Under the driving of the pushing mechanism 20, the adjusting assembly 12 moves horizontally along the length extension direction of the first rotating shaft 10 to move away from or close to the seed discharge groove 11. The driving mechanism 20 is connected with the storage battery mounted on the frame of the seeding machine, so as to realize the automation of the translation of the adjusting assembly 12.

[0070] More specifically, the adjusting assembly 12 comprises a pawl portion which is synchronously rotated with the seed discharge groove 11. The pawl portion is provided with a plurality of pawl bodies 121 along the circumferential direction thereof. The pawl bodies 121 extend to the length direction of the first rotating shaft 10 and are matched with the recessed portion 112. Under the driving of the pushing mechanism 20, the pawl bodies 121 move horizontally along the recessed portion 112.

[0071] The adjusting assembly 12 further comprises a sliding block 122 and a sliding groove 123 which are sleeved on the first rotating shaft 10 and are movably connected with the first rotating shaft 10. The sliding block 122 can slide horizontally along the sliding groove 123, and the sliding groove 123 is parallel to the first rotating shaft 10. One end of the sliding block 122 is connected with the pushing mechanism 20, and the other end is rotatably connected with the pawl portion. That is, the first rotating shaft 10 can rotate relative to the sliding block 122, and the sliding block 122 can move horizontally along the sliding groove 123 under the driving of the pushing mechanism 20, so as to drive the pawl portion to move away from or close to the seed discharge groove 11.

[0072] It is worth mentioning that when the slider 122 slides horizontally, the lug body 121 is always in contact with the recess 112, so that the lug part and the seed slot 11 can always rotate synchronously, and one end of the seed slot 11 is blocked by the lug part, so that the seeds can be prevented from being blown away by the wind.

[0073] Since the recess 112 is used to accommodate seeds, when the lug body 121 moves towards the recess 112, the exposed recess 112 space becomes smaller, and the space capable of accommodating seeds becomes smaller; when the lug body 121 moves away from the recess 112, the exposed recess 112 space becomes larger, and the space capable of accommodating seeds becomes larger. Therefore, through the cooperation of the advancing mechanism 20 and the adjusting assembly 12, the single-seeding quantity of the seeding machine can be realized, and the appropriate planting density can be realized.

[0074] In order to make the seeds in the recess 112 fall more smoothly into the field, the seed slot 11 is specially designed. The recess 112 includes a first plane 1121, a second plane 1122 and a curved surface 1123. The area of the first plane 1121 is smaller than the area of the second plane 1122, and the curved surface 1123 is used to connect the first plane 1121 and the second plane 1122, and the curved surface 1123 protrudes to one side of the center axis of the seed slot 11. The first plane 1121 is smooth and smooth when it transitions to the second plane 1122, so as to avoid the seeds being stuck in the corner.

[0075] With respect to the cross section perpendicular to the center axis of the seed slot 11, the center point of the seed slot 11 is O, the line connecting the lowest point of the curved surface 1123 and the point O is approximately parallel to the first plane 1121, and the line connecting the lowest point of the curved surface 1123 and the point O forms another included angle ∠A with the second plane 1122. The included angle ∠A is obtuse. When a certain recess 112 faces the storage barrel 13, the first plane 1121 is relatively steep, and the second plane 1122 is relatively flat. When the recess 112 faces the funnel part 15 by rotation, the flat second plane 1122 approaches the funnel part 15 first than the first plane 1121. The advantage of this design is that the seeds can fall more smoothly from the recess 112.

[0076] The seeding mechanism further comprises a guide part 14, which is provided with an inner cavity accommodating the seed slot 11, and the upper part of the guide part 14 is connected with the storage barrel 13, and the lower part is connected with the funnel part 15. The bottom of the storage barrel 13 is provided with an opening for the seeds to fall into the recess 112, and the top of the guide part 14 is provided with a through hole corresponding to the opening of the storage barrel.

[0077] One side of the guide part 14 is sealed, and the other side is provided with a through hole for the lug part to pass through. The funnel part 15 is hollow and located directly below the seed slot 11. The seeds fall from the storage barrel 13 to the recess 112, and the rotation of the recess 112 causes the seeds to fall into the field to realize seeding.

[0078] The fertilizing mechanism comprises a second rotating shaft 30 and a fertilizing groove 31, which is sleeved on the second rotating shaft 30 and fixedly connected with the second rotating shaft 30 to realize synchronous rotation. The fertilizing groove 31 is provided with a plurality of grooves 311 along the circumferential direction of the fertilizing groove 31, and the solid fertilizer falls into the grooves 311 from the fertilizer barrel 32 above and is finally scattered into the trench formed by the second furrow opener 62. The number of the grooves 311 is the same as that of the recesses 112.

[0079] In the advancing direction of the seeding machine, the fertilizing groove 31 is located obliquely behind the seed sowing groove 11; in the length extension direction of the first rotating shaft 10, the end face of the fertilizing groove 31 relatively close to the seed sowing groove 11 has a certain gap with the end face of the seed sowing groove 11 relatively close to the fertilizing groove 31, and the horizontal distance between the center point of the fertilizing groove 31 and the center point of the seed sowing groove 11 is about 20 cm, which is roughly equivalent to the distance between the two furrow openers.

[0080] The rotating drive mechanism is connected with the first rotating shaft 10 through the first transmission mechanism 41 and connected with the second rotating shaft 30 through the second transmission mechanism 42, and is used for simultaneously driving the first rotating shaft 10 and the second rotating shaft 30 to rotate, that is, the rotating drive mechanism can synchronize the seeding and fertilizing.

[0081] The rotating drive mechanism comprises a reduction box 43, a drive shaft 44, a crank 45, a rocker 46, a connecting rod 47 and a swing arm 48. The reduction box 43 is connected with a drive motor, and the drive motor and the reduction box 43 are both fixedly installed on the fixed frame 40. The drive shaft 44 is connected with the first rotating shaft 10 through the first transmission mechanism 41 to realize synchronous rotation, and similarly, the drive shaft 44 is connected with the second rotating shaft 30 through the second transmission mechanism 42 to realize synchronous rotation.

[0082] The crank 45 is connected with the output end of the reduction box 43, the rocker 46 is connected with the crank 45 through the connecting rod 47, one end of the rocker 46 is rotationally connected with the fixed frame 40, the other end is connected with the upper end of the swing arm 48 through a pin shaft, and the lower end of the swing arm 48 is connected with the drive shaft 44 through a one-way bearing 49. The rocker 46 and the fixed frame 40 are preferably rotationally connected through a pin shaft.

[0083] The reduction box 43 drives the crank 45 to swing around their connecting point, thereby driving the rocker 46 to swing reciprocally around the connecting point of the rocker 46 and the fixed support of the drive motor, and the rocker 46 drives the swing arm 48 to swing reciprocally around the connecting point of the swing arm 48 and the drive shaft 44.

[0084] More specifically, the one-way bearing 49 comprises an outer ring 491 and an inner ring 492, both coaxial and movably connected, the inner ring 492 being arranged inside the outer ring 491. The outer ring 491 is connected with the swing arm 48 through a key, and the inner ring 492 is sleeved on the drive shaft 44 and fixedly connected with the drive shaft 44, so that the inner ring 492 and the drive shaft 44 rotate synchronously.

[0085] When the swing arm 48 is swung by the rocker 46 to a first direction, the outer ring 491 drives the inner ring 492 to rotate synchronously with the drive shaft 44; when the swing arm 48 is swung by the rocker 46 to a second direction, the inner ring 492 remains stationary, and the outer ring 491 reversely rotates relative to the inner ring 492. It should be noted that the first direction is opposite to the second direction, if the first direction is clockwise, then the second direction is counterclockwise.

[0086] It is worth noting that the swing of the swing arm 48 by the rocker 46 to the second direction is equivalent to completing a single reset, so the drive shaft 44 is intermittently rotated, so that the seed slot 11 and the fertilizer slot 31 are synchronously intermittently rotated, so that the seeds are planted at equal intervals. Appropriate seed spacing is very critical for crop growth. If the seed spacing is too small, it will lead to competition for nutrients, water and sunlight between plants, affecting the normal growth of plants, and even causing some plants to develop poorly due to insufficient growth space. On the contrary, if the seed spacing is too large, it will waste land resources and reduce the yield of crops per unit area.

[0087] The technical solution of the present application, the swing angle range of the swing arm 48 is 30°-120°, which has two advantages, one is to control the single reset time of the swing arm 48, so as to adjust the intermittent time between two rotations of the drive shaft 44, and realize the adjustment of the seed spacing. The second is that the swing angle of the swing arm 48 is related to the number of recesses 112, and also related to the distance between adjacent recesses 112, because the drive shaft 44 rotates once, one of the recesses 112 will rotate to the opposite of the funnel part 15, and the seed will fall from the funnel part 15.

[0088] Preferably, the swing angle of the swing arm 48 is 60°, and the recesses 112 are correspondingly provided with 6, and the grooves 311 of the fertilizer slot 31 are also correspondingly provided with 6.

[0089] A seeder of the present application also provides an energy storage mechanism, which uses solar energy to charge the battery. The energy storage mechanism comprises a solar panel 50 hinged to the side of the seeder frame and a telescopic mechanism 51 movably connected with the solar panel 50, which drives the solar panel 50 to swing around the hinge point under the drive of the drive system.

[0090] More specifically, the telescopic mechanism 51 comprises a support rod 511 fixed to the bottom of the frame, a telescopic rod 512 arranged inside the support rod 511 and in sliding connection with the support rod 511, the top of the telescopic rod 512 being fixedly connected with an adapter plate 513, one end of a retractable arm 514 being fixedly connected with the solar panel 50 and the other end being movably connected with the adapter plate 513, the retractable arm 514 and the adapter plate 513 being preferably connected through a hinge.

[0091] Preferably, the solar panel 50 is arranged at two positions, respectively at the two sides of the frame. The driving system drives the telescopic rod 512 to move vertically along the support rod 511, so as to drive the retractable arm 514 to rotate the solar panel 50.

[0092] During daytime operation, the extension distance of the telescopic rod 512 is adjusted to adjust the angle of the solar panel 50 relative to the sunlight, so as to keep the effective working area of the solar panel 50 maximum, input the electric energy to the battery and realize the effective use of energy.

[0093] After the seeding and fertilizing are completed, the raised soil is filled back into the groove by the soil cover behind the seeder, so as to create favorable conditions for the germination of the seeds.

[0094] The use method of the seeder of the present application is as follows:

[0095] In the forward direction, a pair of furrow cutters on the front side of the seeder open two grooves, wherein the groove opened by the first furrow cutter 61 is used for seeding and the groove opened by the second furrow cutter 62 is used for fertilizing, so as to avoid the direct contact between the seeds and the fertilizer and the occurrence of seedling burning phenomenon;

[0096] The rotating driving mechanism drives the seeding mechanism and the fertilizing mechanism to rotate synchronously and intermittently, the synchronous rotation of the seeding mechanism and the fertilizing mechanism can realize the synchronous seeding and fertilizing, and the intermittent time can be adjusted through the swing angle of the swing arm 48, the intermittent rotation of the seed discharge groove 11 makes the seeds fall into the field intermittently, and the equal-interval seeding of the seeds is realized.

[0097] The seeding mechanism further comprises an adjusting assembly 12, the lugs in the adjusting assembly 12 can move horizontally along the seed discharge groove 11, the space for accommodating the seeds in each recessed part 112 of the seed discharge groove 11 is changed constantly, the number of seeds in the seed discharge groove 11 during one rotation is realized, and the appropriate planting density is realized.

[0098] The seeder is further provided with an energy storage mechanism, the solar panel 50 on the energy storage mechanism is arranged at the side of the frame of the seeder and is hingedly connected with the frame, the angle of the solar panel 50 can be adjusted, so as to be able to face the sunlight directly and to be able to input the electric energy to the battery to the maximum extent.
