Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, in particular to a seedling raising and sowing machine. Background Art

[0002] Oat seeds, an important food and feed crop, possess unique physical properties that can easily cause sticking during sowing. Oat seeds are typically elongated and their surface is not completely smooth, with subtle textures and uneven areas. This increases the contact area between seeds and between them and the inner wall of the seed drill, increasing friction and making them prone to sticking and clinging.

[0003] In the field of agricultural sowing, the seeder, as an important agricultural machine, has greatly improved sowing efficiency and quality. However, when sowing certain types of seeds, such as oats, the seeds tend to stick to the inside of the seeder, causing many problems in the sowing operation.

[0004] First, adhesion will lead to uneven sowing, with dense seeds in some areas and sparse seeds in other areas, affecting the growth consistency and final yield of crops; second, seeds stuck to the inner wall of the seeder may not be discharged smoothly, resulting in seed waste and increased planting costs.

[0005] In order to solve the problem of oat seeds sticking easily in the seeder, the current common methods include pre-treatment of seeds, such as drying, coating with anti-sticking agents, etc., but these methods often have limited effects and may have a certain impact on the quality and germination rate of seeds.

[0006] Therefore, there is an urgent need for a new technical solution to effectively solve the problem of oat seeds sticking inside the planter. Summary of the Invention

[0007] The purpose of the present invention is to provide a seedling raising and sowing machine which can effectively solve the above-mentioned technical problems.

[0008] In order to achieve the purpose of the present invention, the following technical solutions are adopted:

[0009] A seedling sowing machine comprises: a traction frame, a storage box mounted on the top of the traction frame; a sowing mechanism for sowing; and a driven wheel mounted on the front side of the bottom of the traction frame.

[0010] The storage box includes: an outer storage box, an inner storage box movably mounted on the outer storage box, and an elastic member connecting the outer storage box and the inner storage box; a ventilation gap is left between the inner storage box and the outer storage box; a swing rod is hinged on the outer wall of the inner storage box;

[0012] A plurality of ventilation micropores are provided on the inner wall of the inner storage box, and the ventilation micropores are connected to the ventilation gap;

[0013] When the driven wheel rotates, the swing rod is driven to swing through the gear chain transmission, thereby driving the inner storage box to swing; when the inner storage box swings, the ventilation gap is intermittently squeezed.

[0014] Furthermore, the diameter of the ventilation micropores on the side facing the interior of the inner storage box is smaller than the diameter of the ventilation micropores on the side facing the exterior of the inner storage box.

[0015] Furthermore, the outer storage box and the top of the inner storage box are sealed together via a sealing sheet.

[0016] Furthermore, the inner storage box is composed of a fertilizer cavity for storing fertilizer and a seed cavity for storing seeds;

[0017] The bottoms of the fertilizer cavity and the seed cavity are connected with a mixing box; a mixing mechanism for mixing fertilizer and seeds is arranged inside the mixing box.

[0018] Furthermore, the mixing mechanism comprises: a mixing element rotatably mounted on the inner wall of the mixing box, and a discharge baffle hinged to the discharge port at the bottom of the mixing box;

[0019] A third gear is fixedly mounted on the end of the mixing element, and the third gear is transmission-connected to the second gear via a second chain.

[0020] Furthermore, the movable end of the discharge baffle is hinged with a first hinge rod, and the first hinge rod is slidably connected to the inner wall of the mixing box;

[0021] An abutment rod is installed on the mixing element at a position matching the end of the first hinged rod;

[0022] When the mixing element rotates, the abutting rod intermittently pushes the first hinged rod.

[0023] Furthermore, the first hinged rod is composed of an outer rod and an inner rod slidably mounted inside the outer rod;

[0024] The inner wall of the inner rod is evenly rotated and installed with an oblique block along the length direction, and the oblique block is inclined toward the direction of the abutment rod, and the inner wall of the outer rod is installed with a block that cooperates with the oblique block.

[0025] Furthermore, the interior of the inner rod is hollow, the other end of the oblique clamping block is located inside the inner rod, and two adjacent oblique clamping blocks are hinged via a second hinged rod.

[0026] Furthermore, a limit block is installed inside the outer rod at one end close to the discharge baffle;

[0027] A return spring is fixedly mounted on the outer wall of the limit block, and the other end of the return spring is fixedly connected to the outer wall of the inner rod;

[0028] One end of the second hinged rod close to the limiting block protrudes from the interior of the inner rod.

[0029] Compared with the prior art, the present invention has the following beneficial effects: the present application installs a first gear on the driven wheel and transmits the power of the first gear through the first chain to drive the second gear to rotate, and then drives the first rotating shaft to rotate. During the rotation of the first rotating shaft, on the one hand, it drives the inner storage box and the outer storage box to swing relative to each other. On the other hand, when the inner storage box swings, the ventilation gap is intermittently squeezed, so that the air in the ventilation gap is compressed and discharged into the inner storage box through the ventilation micropores, thereby preventing seeds or fertilizers from sticking to the inner wall of the inner storage box.

[0048] like Figures 1 to 14 As shown, the present invention provides a seedling sowing machine, comprising: a traction frame 1 for connecting to a tractor or other power equipment; a storage box 2 installed on the top of the traction frame 1 for storing seeds and fertilizers; a sowing mechanism 3 for sowing; a furrow opener 5 installed at the middle position of the bottom of the traction frame 1 for opening furrows in the soil to facilitate the burying of seeds and fertilizers; a driven wheel 4 installed at the front side of the bottom of the traction frame 1, the driven wheel 4 is used to passively rotate when being towed by a tractor or power equipment; and a scraping roller 6 rotatably installed on the rear side of the traction frame 1, the scraping roller 6 is used to compact the soil after covering, so that the seeds are in close contact with the soil.

[0049] A first gear (not shown) is coaxially fixedly mounted on the rotating shaft of the driven wheel 4, the first gear is meshedly connected to a first chain 42, the first chain 42 is also meshedly connected to a second gear 43, the second gear 43 is coaxially connected to a first rotating shaft 44, an eccentric wheel 45 is mounted on the first rotating shaft 44; a cylindrical connecting block is fixedly mounted on the eccentric wheel 45; the second gear 43 is a double gear, or two coaxially connected gears.

[0050] The storage box 2 includes: an outer storage box 21, an inner storage box 22 installed on the outer storage box 21, and an elastic member 23 installed between the outer storage box 21 and the inner storage box 22; the elastic member 23 is preferably a spring, and the two ends of the spring are respectively connected to the side walls of the inner storage box 22 and the outer storage box 21; a ventilation gap 24 is left between the inner storage box 22 and the outer storage box 21, and they are connected by a spring so that shaking can occur between the inner storage box 22 and the outer storage box 21. The expansion and contraction of the spring can increase the amplitude and frequency of the shaking, thereby more effectively preventing material adhesion.

[0051] The inner storage box 22 consists of a fertilizer chamber 223 for storing fertilizer and a seed chamber 224 for storing seeds; a swing rod 221 is hinged on the outer wall of the inner storage box 22, and the other end of the swing rod 221 is hinged to the cylindrical connecting block on the eccentric wheel 45 on the first rotating shaft 44; when the driven wheel 4 rotates, the first rotating shaft 44 is driven to rotate through the gear chain transmission, and the eccentric wheel 45 is driven to rotate, thereby driving the swing rod 221 to swing back and forth, and then driving the inner storage box 22 to swing, avoiding the accumulation of materials at the bottom of the inner storage box 22, and facilitating the discharge of seeds and fertilizers in the storage box 2; for example, when stored statically for a long time, fine fertilizer particles may gradually concentrate in the bottom corners, and swinging can avoid this situation, ensuring that the fertilizer composition ratio is stable each time the material is discharged.

[0052] A number of ventilation micropores 222 are provided on the inner wall of the inner storage box 22, and the ventilation micropores 222 are connected to the ventilation gap 24 between the outer storage box 21 and the inner storage box 22; the aperture of the ventilation micropores 222 facing the inside of the inner storage box 22 is smaller than the aperture facing the outside of the inner storage box 22; the outer storage box 21 and the top of the inner storage box 22 are sealed by a sealing sheet 25, and the sealing sheet 25 has a bend to meet the expansion and contraction space of the sealing sheet 25, and the sealing sheet 25 is made of rubber or plastic material; the outer storage box 21 and the top of the inner storage box 22 are connected by a retractable rubber or plastic sealing sheet 25 to form a relatively sealed space, which ensures the controllability and stability of air circulation. The bending design of the sealing sheet 25 provides space for its expansion and contraction, so that it can adapt to the swing and extrusion of the inner storage box 22 without affecting the overall sealing effect.

[0053] The design of the ventilation micropores 222 allows air to circulate between the inner storage box 22 and the ventilation gap 24. The aperture of the ventilation micropores 222 facing the inside of the inner storage box 22 is small. On the one hand, it can prevent fertilizers or seeds from getting stuck on the surface of the ventilation micropores 222; for example, when storing fine granular fertilizers, if the aperture is too large, the fertilizer particles can easily be embedded in the micropores, causing blockage or affecting the ventilation effect; on the other hand, when the ventilation gap 24 is squeezed, the air is compressed to form a greater impact force, thereby improving the effect of preventing seeds or fertilizers from sticking to the inner wall.

[0054] As can be seen from the above description, the present application installs a first gear on the driven wheel 4 and transmits the power of the first gear through the first chain 42 to drive the second gear 43 to rotate, and then drives the first rotating shaft 44 to rotate. During the rotation of the first rotating shaft 44, on the one hand, it drives the inner storage box 22 and the outer storage box 21 to swing relative to each other. On the other hand, when the inner storage box 22 swings, the ventilation gap 24 is intermittently squeezed, so that the air in the ventilation gap 24 is compressed and discharged into the inner storage box 22 through the ventilation micropores 222, thereby preventing seeds or fertilizers from sticking to the inner wall of the inner storage box 22; the air introduced into the ventilation micropores 222 can also separate the seeds or fertilizers, increase the fluidity of the seeds or fertilizers, and make them easier to be removed from the inner storage box 22. The seeds or fertilizers are discharged from the storage box 2 or container. During the storage process, the seeds or fertilizers may clump due to moisture or static electricity. The ventilation micropores 222 allow air to reduce the contact between particles and reduce the risk of agglomeration. At the same time, the ventilation micropores 222 can also play a certain cooling role. Seeds are sensitive to temperature. Excessively high temperature may affect their germination rate and growth potential. The internal temperature can be reduced to maintain the quality of the seeds, extend their storage life, and avoid the degradation of seed quality due to heat accumulation. The ventilation micropores 222 promote air flow and may also help regulate internal pressure. When the external environment changes (such as adding materials, vibration, etc.), the micropores can play a buffering role to reduce the impact of external pressure on the internal materials.

[0055] An opening is provided at the bottom of the outer storage box 21, and discharge ports are provided at the bottom of the fertilizer chamber 223 and the seed chamber 224 respectively, and the positions of the discharge ports match those of the openings; an air inlet is left between the opening and the discharge port, and a sealing plate is hinged on the inner wall of the outer storage box 21; when the ventilation gap 24 becomes larger, the swing of the sealing plate can ensure ventilation to the ventilation gap 24, while preventing the ventilation micropores 222 from sucking in seeds or fertilizers, which helps to maintain internal air circulation and prevent materials from clogging the micropores; when the ventilation gap 24 is compressed, the sealing plate is driven to seal the air inlet, which has a simple structure and does not require additional complex control mechanisms; among them, the air inlet generally does not need to be completely sealed. When the ventilation gap 24 is compressed, a small amount of air leakage does not affect the effect of the ventilation micropores 222, thereby simplifying the process and manufacturing costs to a certain extent.

[0056] A mixing box 225 is installed at the bottom of the discharge port. The feed port of the mixing box 225 is connected to the above-mentioned discharge port through a connecting pipe. A mixing mechanism for mixing fertilizers and seeds is installed inside the mixing box 225.

[0057] The mixing mechanism includes: a mixing piece 2241 rotatably mounted on the inner wall of the mixing box 225, a discharging port being provided at the bottom of the mixing box 225, a discharging baffle 2242 being hingedly connected to the discharging port; a first hinged rod 22421 being hingedly connected to the movable end of the discharging baffle 2242, a slide being provided at the end of the first hinged rod 22421 away from the discharging baffle 2242, a slider being fixedly mounted on the inner wall of the mixing box 225, the slide being slidably connected to the slider; a buffering gasket being mounted at the end of the first hinged rod 22421; an abutting rod 22411 being further mounted on the mixing piece 2241, The position matches the position of the buffer gasket; a third gear 2243 is fixedly installed on the outer end of the mixing piece 2241, and the third gear 2243 is connected to the second gear 43 through a second chain 2244; when the driven wheel 4 rotates, it also drives the mixing piece 2241 to mix the materials in the mixing box 225; when the mixing piece 2241 rotates, it drives the abutment rod 22411 to rotate, and makes the abutment rod 22411 indirectly contact with the first hinged rod 22421. When the abutment rod 22411 contacts with the first hinged rod 22421, it drives the first hinged rod 22421 to slide along the path of the slide groove.

[0058] The first hinged rod 22421 consists of an outer rod 224211 and an inner rod 224212 slidably installed inside the outer rod 224211; the inner wall of the inner rod 224212 is evenly rotated and installed with an oblique block 2242121 along the length direction, and the oblique block 2242121 is inclined toward the direction of the abutment rod 22411, and the inner wall of the outer rod 224211 is installed with a slot that cooperates with the oblique block to limit the inner rod 224212.

[0059] The interior of the inner rod 224212 is hollow, and the other end of the oblique blocking block 2242121 is located inside the inner rod 224212. The two adjacent oblique blocking blocks 2242121 are hinged by the second hinged rod 2242122, so that the oblique blocking blocks 2242121 can rotate synchronously; a limiting block 2242123 is installed at one end of the outer rod 224211 close to the discharging baffle 2242, and a return spring 2242124 is fixedly installed on the outer wall of the limit block 2242123, and the other end of the return spring 2242124 is fixedly connected to the outer wall of the inner rod 224212; the end of the second hinged rod 2242122 close to the limit block 2242123 protrudes from the interior of the inner rod 224212 and can contact the limit block 2242123.

[0060] When the mixing element 2241 rotates, the contact rod 22411 intermittently drives the first hinged rod 22421 to move. During this process, the inner rod 224212 will continuously move toward the limit block 2242123. When the protruding end of the second hinged rod 2242122 abuts against the limit block 2242123, the limit block 2242123 is forced to swing, and the oblique block 2242121 of the inner rod 224212 retracts into the inner rod 224212. At the same time, the discharge baffle 2242 is forced to open, and as the mixing element 2241 continues to rotate, the contact rod 22411 drives the first hinged rod 22421 to move. During this process, the inner rod 224212 will continuously move toward the limit block 2242123. The connecting rod 22411 is gradually separated from the first hinged rod 22421. Since the oblique blocking block 2242121 is located inside the inner rod 224212 at this time, the inner rod 224212 slides away from the limit block 2242123 under the action of the reset spring 2242124, so that the inner rod 224212 is reset; until the next cycle is entered during the rotation of the mixing element 2241; with this arrangement, the evenly mixed materials can be intermittently discharged from the mixing box 225 in a quantitative manner during the process of the mixing element 2241 mixing fertilizers and seeds.

[0061] In the process of following the movement and rotation of the tractor, the moving wheel of the present application drives the inner storage box 22 to swing on the one hand, further preventing the seeds or fertilizers from sticking to the inner wall of the inner storage box 22; on the other hand, it drives the mixing element 2241 to mix the fertilizer and seeds evenly; at the same time, in the process of the mixing element 2241 mixing the fertilizer and seeds, the evenly mixed materials are intermittently discharged, which has the effect of quantitative discharge, avoiding the discharge of too much material at one time, resulting in waste or uneven application.

[0062] The sowing mechanism 3 includes: a seeder 31 that discharges seeds and fertilizers, a feed pipe 32 that transports the seeds discharged by the seeder to the furrow opener 5, and a soil coverer that covers the seeds with the soil next to it after the seeds fall into the furrow; the feed end of the seeder 31 is connected to the outlet at the bottom of the mixing box 225; the seeder 31 is a socket-type seeder or a spoon-wheel-type seeder.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.
