Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sowing, and in particular relates to a seed sowing and scattering device. Background Art
[0002] Sowing is the process of sowing crops in the field. As the sown seeds grow and develop in the soil, they gradually grow into seedlings. During the growth and development of seeds, the factors that affect the growth and development of seeds mainly include biological competition between organisms. That is, if the sowing density is too high, the seedlings that develop from the seeds will have biological competition during the growth process due to the limited growth space, which is reflected in the low yield in the later stage.
[0003] Therefore, in order to avoid the seeds being too densely sown during sowing, the sowing speed of the seeds is controlled in the actual work process. Especially for seeds with small particle sizes, it is very easy to cause a high sowing density due to the small particle size and fast sowing speed.
[0004] Specifically, during the sowing process, the seeds are stored in a plurality of integrated sowing boxes, so that the sowing boxes sow the seeds in the field.
[0005] However, during the operation, the seeds fall vertically onto the uneven ground and cannot bounce around. Especially when sowing on rainy days, the seeds fall to the ground and accumulate directly in a specific position, causing the sowing density to be too high. Subsequently, too many plants grow in that position, and the biological competition during plant growth is too great, which affects the yield. Utility Model Content

[0044] Example 1
[0045] like Figure 1-5 As shown, a seed sowing and scattering device comprises a sowing bin 1, the bottom of which is assembled and connected with a plurality of sowing box assemblies, and wheat seeds are sown through the sowing box assemblies.
[0046] Specifically, the seeding box components are arranged in two rows at the bottom of the seeding bin 1, and each row includes a plurality of seeding box components spaced apart from each other.
[0047] Specifically, the seeding box assembly includes a seed box 4, and a seeding tube 3 is integrally formed at the bottom of the seed box 4; the box opening of the seed box 4 is fixed to the bottom of the seeding bin 1. Specifically, two rows of mounting holes are arranged at intervals on the left and right at the bottom of the seeding bin 1. During the sowing process, the seeds enter the seed box 4 from the mounting holes, and are discharged from the sowing tube 3 for sowing.
[0048] In order to realize the ejection of seeds during the sowing process, the above-mentioned seed sowing and scattering device also includes a seed ejection mechanism arranged below the 4 groups of sowing box components; the seed ejection mechanism includes suspension arms 5 respectively installed on the side walls of both sides of the sowing bin 1, and a long connecting shaft 54 is fixedly connected between the lower ends of the suspension arms 5.
[0049] Specifically, spring plate components 6 are installed on both sides of the long connecting shaft 54, and the spring plate components 6 include a lower support plate 62, and a plurality of springs 63 are fixedly connected to the top of the lower support plate 62, and an upper spring plate 61 is fixedly connected between the tops of the springs 63; the unloaded seeds are ejected and sown through the upper spring plate 61. The lower support plate 62 and the upper spring plate 61 are arranged in an outwardly inclined manner, so that the unloaded seeds hit the upper spring plate 61 during the working process, and the upper spring plate 61 made of elastic plastic material is used to give the seeds elastic force to eject the seeds, so as to increase the sowing range and avoid too concentrated sowing of seeds.
[0050] During the working process, since the upper spring plate 61 and the lower support plate 62 are fixedly connected by the spring 63, during the sowing movement, the seeder traveling in the field is in a bumpy movement state, and the upper spring plate 61 is fixedly connected by the spring 63. Therefore, the upper spring plate 61 keeps shaking irregularly, and the falling seeds hit the shaking upper spring plate 61, thereby changing the ejection speed and angle of the seeds, thereby further ensuring that the ejected seeds can be distributed over a large range.
[0051] Specifically, during operation, the entire device is installed on a seed drill (specifically, the same as the existing method, mounting seats 11 are installed on the left and right sides of the front and rear side walls of the seeding bin 1, and the mounting seats 11 are fastened to the frame of the seed drill).
[0052] Example 2
[0053] like Figure 1-6As shown, based on the structure of Example 1, in order to further improve the shaking effect of the upper spring plate 61 and the lower support plate 62, the upper spring plate 61 is added to eject the seeds with different forces and directions, so as to fully and widely disperse the seeds in the lower row. The upper end of the suspension arm 5 is installed on the sowing bin 1 through a spring lifting structure. During the sowing process, the suspension arm 5 and the spring plate component 6 swing up and down through the spring lifting structure.
[0054] Specifically, the spring lifting structure includes a sliding port 51 opened at the upper end of the suspension arm 5, a sliding seat slidably connected to the sliding port 51 is fixedly connected to the side wall of the sowing bin 1, a vertical guide rod is fixedly connected to the sliding port 51, and the vertical guide rod is slidably connected to the sliding seat. The spring lifting structure also includes an upper spring 53 and a lower spring 52 sleeved on the vertical guide rod; the bottom of the upper spring 53 and the top of the lower spring 52 are respectively fixedly connected to the top and bottom positions of the sliding seat; the top of the upper spring 53 and the bottom of the lower spring 52 are respectively fixedly connected to the top and bottom positions in the sliding port 51.
[0055] In the working process, since the whole device is installed on the seeder, and the seeder is traveling on the bumpy land, the suspension arm 5 is constantly elastically lifted and lowered in height through the spring lifting structure during the bumping process of the seeder. Specifically, since the whole device has inertia, when the seeder is in the bumpy driving state, the suspension arm 5 carries the connected upper spring plate 61 and the lower support plate 62 to be elastically lifted and lowered. For example, during the rising process, the upper spring 53 is compressed and the lower spring 52 is stretched, and vice versa, the deformation of the spring 63 is opposite. In this process, the movement amplitude of the upper spring plate 61 and the lower support plate 62 is increased, and the seeds that hit the upper spring plate 61 can be further fully ejected in different directions, so as to prevent the seeds from falling into the field too concentratedly.
[0056] Specifically, the front and rear ends of the long connecting shaft 54 are respectively fixedly connected with connecting parts, and the lower support plate 62 is fixedly connected to the connecting parts; the connecting part includes a connecting sleeve 541 threadedly connected to the long connecting shaft 54, and mounting strips 5411 are welded on the left and right side walls of the connecting sleeve 541, and a bayonet is provided on the mounting strip, and the end of the lower support plate 62 is clamped in the bayonet, and the mounting strip is threadedly connected with a fastening bolt fastened to the lower support plate 62.
[0057] The lower support plate 62 is fixedly installed in the above manner.
[0058] Implementation 3
[0059] like Figure 1-6As shown, in this embodiment, based on the structure of embodiment 2, the seeds to be sown are placed in a sowing bin 1. In order to adjust the speed at which the seeds enter the sowing box 4 and further change the distribution density of the seeds, a seed placing control mechanism is installed and connected in the sowing bin 1.
[0060] Specifically, the seed placing mechanism includes a placing plate 2 hinged on both sides of the sowing bin 1; when the placing plates 2 on the left and right sides are in a horizontal state, the placing plates 2 seal the lower end of the sowing bin 1, and the seeds are carried on the top of the placing plates 2.
[0061] At this time, the discharge plate 2 is rotated, and the seeds are discharged from between the discharge plates 2 to the bottom of the sowing bin 1, and are broadcast from the four groups of components of the sowing box.
[0062] Therefore, by adjusting the rotation amplitude of the discharge plate 2, the size of the gap between the discharge plates 2 and between the discharge plate 2 and the side wall of the sowing bin 1 can be adjusted to change the speed at which the seeds enter the bottom of the sowing bin 1 and the seed box 4. Specifically, the front and rear ends of the discharge plate 2 are respectively fixedly connected with a rotating shaft 212, and the outer wall of the sowing bin 1 is fixedly connected with a locking structure 21 for locking the rotating shaft 212.
[0063] The locking structure 21 comprises a locking sleeve 211 fixedly connected to the sowing bin 1 , the rotating shaft 212 is rotatably connected in the locking sleeve 211 , and a locking bolt 213 for locking the rotating shaft 212 is threadedly connected to the locking sleeve 211 .
[0064] After loosening the locking bolt 213, the discharge plate 2 is flipped in the opposite direction, and then the locking bolt 213 is pressed against the locking shaft. The seeds fall into the bottom of the bin from the gaps between the discharge plates 2 and the gaps between the discharge plates 2 and the side walls of the sowing bin 1 and enter the seed box 4 from the mounting hole.
[0065] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
