Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural machinery, in particular to a finger-clamp type seeder. Background Art
[0002] In the process of crop production, the sowing process is crucial. If the previous multi-seed sowing method is used, the seedlings will compete for nutrients and water in the soil. The use of mechanical precision sowing can achieve the purpose of complete, uniform and strong seedlings, no thinning, saving costs and increasing efficiency. It is an agricultural machinery energy-saving and emission-reduction technology that saves seeds, land and labor, and has been widely promoted in agricultural production practice. The existing solution is to use single-seed sowing, that is, use the seed clamping structure to clamp only one seed at a time, and then put the single seed into the seed drop port, and sow through the seed outlet channel.
[0003] When multiple seeds are taken at a time, since the seeds are piled together, when multiple seeds fall from the seed drop port into the seed outlet, the seeds that fall first will have a certain buffering effect on the seeds that fall later. Even if the surface of the seeds that fall first is damaged, the subsequent seeds that fall will avoid surface damage due to the buffering effect of the seeds that fall first, thereby ensuring that not all seeds are damaged each time they are sown. However, when only one seed is clamped each time, the seed will directly contact the seed outlet channel. When only one seed is sown each time, once the seed is damaged, the seed at that location will not grow, resulting in a waste of land. Especially when the land is sown in a herringbone pattern, once the seed is damaged and the crop cannot grow, it will destroy the arrangement of crops in the field, resulting in a waste of land and light.

[0020] (1) The utility model is a finger-clip type seeder, which can sow seeds at intervals by arranging alternately arranged seed clamping areas and spacing areas on the seed clamping unit, and the spacing areas are not less than the spacing between the seed clamps. When two seeders sow seeds at the same time, a herringbone sowing can be achieved, so that the crops will not block each other after growth, and the land and sunlight can be fully utilized.

A circle of first fixing plates 32 are respectively extended outward from the bottom and the opening of the barrel, wherein the first fixing plate 32 located at the bottom of the barrel is located in the same plane as the seeding base plate 31 and is connected, that is, the first fixing plate 32 is a part of the seeding base plate 31 extending outward. The first fixing plate 32 located at the opening of the barrel is parallel to the seeding base plate 31. The front cover plate 2 and the rear cover plate 5 are respectively connected to a first fixing plate 32, and the three together form a receiving cavity. The front cover plate 2 is provided with a seed entry channel 1, and the rear cover plate 5 is provided with a seed exit channel 4. Both the seed entry channel 1 and the seed exit channel 4 are connected to the accommodating cavity. The seed clamping unit 7 is used to transport seeds from the seed entry channel 1 to the seed exit channel 4.
[0046] In this embodiment, the seed clamping unit 7 is arranged in the cylindrical structure formed by the seeding plate 3, and the seed clamping unit 7 is arranged close to the seeding base plate 31. Figure 5 and Figure 6 The seed clamping unit 7 of this embodiment includes a seed clamping area and a spacing area, which are arranged alternately, and a plurality of seed clamps 76 are arranged in the seed clamping area; the spacing area is not less than the spacing between the seed clamps 76. Multiple seed clamping areas and spacing areas can be arranged on the seed clamping unit 7. When the number of seed clamping areas and spacing areas is greater than one, the seed clamping areas and spacing areas are arranged alternately. One seed clamping area and spacing area can also be arranged on the seed clamping unit 7, that is, a part of the area of the seed clamping unit 7 is the seed clamping area, and the other areas are all spacing areas. The seed clamping unit 7 of this embodiment is only provided with one seed clamping area and one spacing area.
[0047] The seed clamping unit 7 of this embodiment includes a circular rotating member 71 and a truncated table 79, wherein a seed clamping side plate 73 extending to one side is arranged on the circumference of the rotating member 71, and the rotating member 71 and the seed clamping side plate 73 together form a bowl-shaped structure. A seed clamping shaft hole 72 is arranged at the center of the rotating member 71, and the rotating member 71 rotates around the seed clamping shaft hole 72 as the center of the circle. The truncated table 79 is arranged at the center of the rotating member 71 and is fixed, and the truncated table 79 and the seed clamping side plate 73 are located on the same side. In this embodiment, the side of the truncated table 79 away from the rotating member 71 is divided into a plane section 791 and a protruding section 792, and there is an inclined transition between the two. The protruding section 792 is farther away from the rotating member 71 than the plane section 791, thereby forming an uneven structure.
[0048] A plurality of limiting openings 74 are provided on the seed clamping side plate 73, and a seed clamping rod 75 is arranged in the limiting opening 74. One end of the seed clamping rod 75 contacts the round table 79, and the other end is provided with a seed clamp 76, which extends to the outside of the rotating member 71. The seed clamping rod 75 of this embodiment is in close contact with the plane section 791 and the protruding section 792 of the round table 79, and can slide on the plane section 791 and the protruding section 792. In this embodiment, the limiting opening 74 allows the seed clamping rod 75 to move vertically relative to the rotating member 71, and allows the seed clamping rod 75 to rotate with the rotating member 71. The seed clamping rod 75 forms a lever structure with the contact position with the seed clamping side plate 73 as a fulcrum. When one end of the seed clamping rod 75 slides on the plane section 791, the other end of the seed clamping rod 75 moves with the seed clamp 76 close to the sowing base plate 31, thereby clamping the seeds. When one end of the seed clamping rod 75 slides on the protruding section 792, the other end of the seed clamping rod 75 drives the seed clamp 76 away from the sowing base plate 31, thereby releasing the seed and re-clamping another seed.
[0049] In this embodiment, a reset member is also provided on the seed clamping rod 75 to help the seed clamping rod 75 return to its original position. The reset member includes a spring 77. In this embodiment, a total of four seed clamping rods 75 are provided, and a spring 77 is connected to each of the two sides of each seed clamping rod 75, and the spring 77 is connected to another seed clamping rod 75. The springs 77 of the two outermost seed clamping rods 75 are respectively connected to a spring fixing rod 78, forming a structure of "spring fixing rod 78-spring 77-seed clamping rod 75-spring 77-seed clamping rod 75-spring 77-spring fixing rod 78". When the seed clamping rod 75 is located on the protruding section 792, the spring 77 will be stretched. When the seed clamping rod 75 returns to the plane section 791, the spring 77 resets the seed clamping rod 75 to ensure that the other end of the seed clamping rod 75 can make the seed clamp 76 close to the sowing substrate 31. In this embodiment, a seed drop opening 33 is provided on the seeding base plate 31 , and the seed drop opening 33 connects the seed outlet channel 4 with the seeding plate 3 . When the seed clamp 76 moves to the seed drop opening 33 , the seed clamp 76 releases the seed, and the seed enters the seed outlet channel 4 through the seed drop opening 33 .

In this embodiment, the rotating disk 8 includes a rotating table 81, and a plurality of partitions 82 are arranged at intervals along the circumference of the rotating table 81, and the partitions 82 can push the seeds into the seeding channel 4 to prevent the seeds from not entering the seeding channel 4. A rotating disk shaft hole 83 is provided at the center of the rotating table 81, and a rotating shaft passes through the rotating disk shaft hole 83 and the seed clamping shaft hole 72 at the same time, driving the rotating disk 8 to rotate coaxially with the rotating member 71.
[0051] The rear cover plate 5 of this embodiment includes a bottom plate 51, and a second fixing plate 52 connected to the first fixing plate 32 is arranged on the circumference of the bottom plate 51.

[0052] Combination Figure 7-Figure 8 The buffer unit 6 of this embodiment includes a buffer member 64, and the buffer member 64 includes a buffer plate 642. A plurality of buffer bumps 643 are arranged on the buffer plate 642. The buffer unit 6 also includes a buffer substrate 61. A surrounding plate 63 is arranged on the buffer substrate 61. The buffer substrate 61 and the surrounding plate 63 form a groove, and the buffer member 64 is arranged in the groove. A buffer convex plate 641 is arranged circumferentially on the buffer plate 642, and the buffer convex plate 641 contacts the buffer substrate 61; the height of the buffer convex plate 641 is higher than the buffer bumps 643. An ear plate 62 is also arranged on the buffer substrate 61, and the ear plate 62 has a hole. The buffer unit 6 is fixed to the rear cover plate 5 by screws passing through the ear plate 62.

The buffer convex plates 641 are higher than the buffer bumps 643. The buffer bumps 641 are in contact with the buffer substrate 61 to provide support for the buffer 64. The buffer bumps 643 located in the middle do not contact the buffer substrate 61 when the seed does not fall. When the seed falls on the buffer 64, the interval between the buffer bumps 643 and the buffer substrate 61 plays a first buffering role, and the buffer bumps 643 play a second buffering role, thereby completely eliminating the impact force and avoiding damage to the seed. The buffer 64 of this embodiment is made of flexible materials such as rubber.
[0053] In this embodiment, the seed clamping area and the spacing area are arranged alternately on the seed clamping unit 7, and the spacing area is not less than the spacing between the seed clamps 76, so that the seed drill can sow at intervals. When two seed drills sow at the same time, the herringbone sowing can be achieved, so that the crops will not block each other after growth, and the land and sunlight are fully utilized. At the same time, in order to make full use of the land and sunlight and avoid damage caused by collision when the seeds fall, the buffer 64 is provided at the entrance of the seed outlet channel 4 in this embodiment to buffer the seeds when they fall, thereby avoiding damage to the seeds.
