Description

Technical Field

[0001] The invention relates to the field of agricultural sowing, in particular to a sowing device with deep loosening and fertilizing functions and shallow ground rotation. Background Art

[0003] Patent: CN205040214U discloses a corn planter with a deep loosening and fertilizing shovel, comprising a frame, a seeding box and a deep loosening and fertilizing shovel, the rear end of the frame is equipped with a rear wheel through a supporting frame, the rear wheel is a horizontally placed steel cage cylinder structure, end covers are provided at both ends of the rear wheel, a plurality of steel bars are arranged equidistantly along the end covers between the end covers and welded into a cylindrical shape, a seeding device is provided in the seeding box, and a seed loading box and a fertilizer box are provided on the upper part of the seeding box, the deep loosening and fertilizing shovel comprises a sheet-shaped straight shovel handle and an arc shovel surface, the rear side of the straight shovel handle is connected to the seed dropper, the front end of the straight shovel handle is provided with a horizontal panel, the top of the arc shovel surface is provided with arc-shaped fins, and both sides of the arc shovel surface are provided with sharp teeth. The utility model improves working efficiency, can adjust the row spacing between seeds, effectively eliminates the slippage between the ground wheel and the soil, is conducive to fertilizing and sowing operations while improving the deep loosening effect, and has a good deep loosening effect;

[0004] In the above technology, when sowing, it is the same as most of the existing methods. A drum with multiple grooves for receiving seeds is set inside the box to rotate, so as to achieve the effect of intermittent loading and discharging sowing during the rotation of the drum. However, since the seeds easily contain fine particles such as debris, when the drum is rotated, the fine particles are easily blocked on the outer wall of the drum and in the rotating cavity when the drum rotates, thereby affecting the rotation of the drum. It is easy to get stuck or worn after long-term use. In addition, in the existing technology, after mixing fertilizer and water, manual stirring is usually insufficient, and it is not convenient to stir while fertilizing. In order to make the stirring more uniform, improvement is needed. For this reason, we propose a sowing equipment with deep loosening and shallow surface rotation. Summary of the Invention

DETAILED DESCRIPTION

[0036] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Example

[0038] like Figure 1 and Figure 2 As shown, a sowing device with deep loosening and fertilizing and surface shallow rotation is provided, comprising a frame 1, and a connecting frame 6 is fixedly connected to the left side of the upper surface of the frame 1;

[0039] A plurality of trenching knives 7 are provided on the left side of the lower surface of the frame 1;

[0040] A moving wheel 8 is symmetrically fixed to the right side of the lower surface of the frame 1;

[0041] The frame 1 serves as the core supporting structure, and the left connecting frame 6 enables quick connection with the traction device to adapt to the matching requirements of different power sources;

[0042] The trenching blades 7 are designed with multiple groups of arrangements, which can complete deep loosening and trenching operations;

[0043] The moving wheel 8 supports the right side of the frame 1, making it easier for the frame 1 to move when it is pulled.

[0044] like Figure 3 As shown, a rotary tillage mechanism 2 is provided on the inner side of the frame 1;

[0045] The rotary tillage mechanism 2 includes a rotating rod 201. The two ends of the rotating rod 201 extend through the front and rear of the frame 1 respectively and are rotatably connected to the frame 1 via a rotating shaft. A plurality of rotary tillage wheels 202 are fixedly connected to the outer wall of the rotating rod 201.

[0046] By driving the rotating rod 201 to rotate, the rotary tillage wheel 202 is driven to rotate and till the soil, which meets the needs of shallow tillage and is compatible with the furrowing knife 7 for deep tillage, thus realizing the combined operation of rotary tillage and deep tillage.

[0047] like Figure 4 As shown, a storage mechanism 3 is provided above the rack 1;

[0048] The storage mechanism 3 includes a storage box 301. The bottom of the storage box 301 and the upper surface of the frame 1 are fixedly connected to two support plates 302. The rear surface of the support plate 302 located in front of the upper surface of the frame 1 is fixedly connected to an electric push rod 303. The rear end of the output end of the electric push rod 303 is fixedly connected to an L-shaped docking plate 304.

[0049] The lower surface of the storage box 301 is provided with a plurality of through-type discharge holes 305, and the lower surface of the L-shaped docking plate 304 is integrally formed with a plurality of docking tubes 306;

[0050] The storage box 301 is rigidly connected to the frame 1 through the double support plates 302 to form a support structure to ensure the stability of material storage;

[0051] The electric push rod 303 is fixedly connected to the L-shaped docking plate 304. By controlling the electric push rod 303, the docking tube 306 is driven to be precisely aligned with the discharge hole 305, thereby realizing controlled release of seeds.

[0052] like Figure 4 、 Figure 5 and Figure 6 As shown, a sowing mechanism 4 is provided below the storage mechanism 3;

[0053] The sowing mechanism 4 includes a shaft 401, the outer wall of the shaft 401 is fixedly connected to a sowing barrel 402, the outer wall of the shaft 401 is located on the front surface and the rear surface of the sowing barrel 402 and is fixedly connected to a disc 403, the inner wall of the disc 403 is fixedly connected to a plurality of fixed blocks 404, the inner side of the fixed block 404 is slidably connected to a guide rod 405, and between the two front and rear opposite guide rods 405 and located on the outer side of the sowing barrel 402, a fan-shaped petal 406 is fixedly connected together, the number of the fixed blocks 404 inside a single disc 403 is four, the number of the fan-shaped petals 406 is four, and the cross-section of a single fan-shaped petal (406) is a quarter circle;

[0054] The outer wall of the shaft 401 is located inside the two discs 403 and is fixedly connected to a squeeze disc 407. The outer wall of the squeeze disc 407 is symmetrically fixedly connected to a squeeze block 408.

[0055] A plurality of through-type inoculation grooves 410 are provided above the outer side wall of the sowing tube 402, a plurality of material receiving grooves 411 are provided at the tops of the two fan-shaped petals 406 above the shaft 401, and a plurality of sowing grooves 412 are provided at the bottoms of the two fan-shaped petals 406 below the shaft 401. A spring 413 is fixedly connected between the guide rod 405 and the fixed block 404. The number of the plurality of docking tubes 306, the number of the plurality of inoculation grooves 410, the number of the plurality of material receiving grooves 411 and the number of the plurality of sowing grooves 412 are the same, and their positions correspond one to one.

[0056] When the electric push rod 303 controls the butt joint 306 to align with the discharge hole 305, the seeds in the storage box 301 can be discharged into the sowing cylinder 402 through the butt joint 306, the discharge hole 305, the receiving groove 411, and the inoculation groove 410 for storage. After the seeds are discharged, the butt joint 306 and the discharge hole 305 are misaligned by the electric push rod 303 to stop discharging the seeds.

[0057] When the driving shaft 401 rotates, the sowing cylinder 402 rotates, and the multiple groups of inoculation grooves 410 receiving the seeds will dock with the multiple sowing grooves 412 in sequence. Under the action of gravity, the seeds fall from the inoculation grooves 410 and fall to the ground through the sowing grooves 412 to achieve sowing. The multiple groups of inoculation grooves 410 arranged on the outside of the sowing cylinder 402 are docked with the receiving grooves 411 in sequence to achieve sowing. The seeds are received and sown by docking with the multiple sowing grooves 412 in sequence. In this way, intermittent sowing of seeds can be achieved, so that the sown seeds are evenly distributed.

[0058] During the rotation of the shaft 401, the multiple extrusion blocks 408 on the extrusion disk 407 will intermittently squeeze the multiple guide rods 405 in sequence, compressing the spring 413 and causing the guide rods 405 to slide along the inside of the fixed block 404, so that the multiple fan-shaped petals 406 closed on the outside of the seeding barrel 402 to form a closed hollow cylinder move together with the guide rods 405, so that the multiple fan-shaped petals 406 can be opened two by two and away from the seeding barrel 402, and then the dust and fine particles in the gap between the hollow cylinder formed by the fan-shaped petals 406 and the seeding barrel 402 can be discharged, avoiding blockage and causing problems such as wear of components;

[0059] During the process of multiple fan-shaped petals 406 opening one by one, since the two extrusion blocks 408 and the two groups of inoculation grooves 410 are distributed in a rectangular shape, the extrusion blocks 408 squeeze the guide rod 405 to drive the fan-shaped petals 406 to move, which will cause the two fan-shaped petals 406 that are not in contact with the two groups of inoculation grooves 410 to open, thereby avoiding the problem that the fan-shaped petals 406 open when the inoculation groove 410 tilts downward, causing the seeds to fall prematurely. The inoculation groove 410 can only be unloaded by docking with the sowing groove 412 when it is rotated vertically downward, avoiding the problem of uneven sowing. At the same time, by blocking the outside of the sowing barrel 402 with multiple fan-shaped plates 406, the problem of seeds flying due to centrifugal rotation in the existing technology can be avoided.

[0060] like Figure 1 and Figure 7 As shown, a fertilizer application mechanism 5 is provided on the right side of the upper surface of the frame 1;

[0061] The fertilizing mechanism 5 includes a liquid storage tank 501 , and a plurality of hollow disks 502 are rotatably connected to the lower surface of the liquid storage tank 501 via a rotating shaft. A drainage pipe 503 is integrally formed on the lower surface of the hollow disk 502 below the liquid storage tank 501 .

[0062] The lower surface of the interior of the liquid storage tank 501 and the outer sides of the multiple hollow disks 502 are fixedly connected with a gear ring 504, the upper surface of the hollow disk 502 is fixedly connected with a stirring seat 505, the upper surface of the stirring seat 505 is rotatably connected to a stirring rod 506 via a rotating shaft, the bottom end of the stirring rod 506 extends to the bottom of the stirring seat 505 and is fixedly connected to a gear 507, the outer side wall of the gear 507 is meshed with the outer side wall of the gear ring 504, the outer side wall of the discharge pipe 503 is fixedly connected to a transmission wheel 3 508, the right side of the liquid storage tank 501 is fixedly connected to a motor 2 509, the bottom end of the output end of the motor 2 509 is fixedly connected to a transmission wheel 4 510, the outer side wall of the transmission wheel 4 510 and the outer side walls of the multiple transmission wheels 3 508 are commonly connected to a transmission belt 2 511;

[0063] The outer wall of the gear ring 504 and the outer wall of the hollow disk 502 are both provided with a plurality of through-type drainage holes 512;

[0064] The second motor 509 is started, and under the drive of the third and fourth transmission wheels 508 and 510, the plurality of discharge pipes 503 can be controlled to drive the plurality of hollow disks 502 to rotate together, so that the stirring base 505 can drive the stirring rod 506 to move along with the rotation of the hollow disks 502 to achieve stirring. During the stirring process, the stirring rod 506 rotates along with the hollow disks 502, and the gear 507 is engaged with the gear ring 504 to drive the stirring rod 506 to rotate on its own, thereby achieving rotational stirring. The stirring rod 506 can expand the stirring range when it moves along with the hollow disks 502.

[0065] During the rotation of the hollow disk 502, the multiple drainage holes 512 provided on the outer wall intermittently dock with the multiple drainage holes 512 on the gear ring 504. During the docking process, the fertilizer stored in the liquid storage tank 501 can flow into the hollow disk 502 and be discharged through the drainage pipe 503, thus achieving the effect of stirring and intermittently draining fertilizer at the same time.

[0066] like Figure 8 As shown, in state S1, the inoculation slot 410 and the receiving slot 411 are in a docking state, and at this time, some seeds can be injected into the sowing cylinder 402 through the receiving slot 411 and the inoculation slot 410;

[0067] As the seeding cylinder 402 rotates, the relationship between the seeding cylinder 402 and the plurality of fan-shaped petals 406 changes through three states: S2, S3, and S4. In the S2 and S4 states, two obliquely opposite fan-shaped petals 406 move back to back and open away from the outside of the seeding cylinder 402, making it easier for debris stuck in the gap to fall off automatically. At this time, the inoculation slot 410 is shielded by the two inactive obliquely opposite fan-shaped petals 406, preventing seeds from being thrown away during rotation.

[0068] As the sowing cylinder 402 continues to rotate to the S5 state, the inoculation groove 410 faces downward and connects with the sowing groove 412. At this time, the seeds stored in the sowing cylinder 402 will fall out for sowing.

[0069] Then the seeding barrel 402 continues to rotate, and the relationship between the seeding barrel 402 and the fan-shaped petals 406 will change from three states S6, S7 and S8. In the S6 and S8 states, two obliquely opposite 406 will move back to back and open away from the outside of the seeding barrel 402, which makes it easier for debris stuck in the gap to fall off automatically. At this time, the inoculation groove 410 will be blocked by the two inactive obliquely opposite fan-shaped petals 406 to avoid the problem of seeds being thrown away during rotation.

[0070] Finally, as the sowing cylinder 402 completes one rotation, it returns to the S1 state. In this process, single rotation sowing can be achieved, and the problems of seeds being easily thrown away and debris blocking the rotation in the prior art can be avoided.

[0071] During the rotation of the seeding barrel 402, the squeezing disk 407 is driven to rotate together, so that the two squeezing blocks 408 on the outer wall of the squeezing disk 407 intermittently squeeze the two opposite guide rods 405 to slide along the inner side of the fixed block 404, thereby driving the fan-shaped petals 406 to move and expand, achieving the effect of automatically cleaning debris.

[0072] like Figure 1 and Figure 2As shown, the front and rear ends of the rotating rod 201 are fixedly connected to the transmission wheel 1 203, the two ends of the shaft 401 respectively penetrate the opposite sides of the two support plates 302, and are respectively rotatably connected to the two support plates 302 via a rotating shaft, the front and rear ends of the shaft 401 are fixedly connected to the transmission wheel 2 409, and the outer side walls of the transmission wheel 1 203 and the transmission wheel 2 409 on the same side are jointly connected to the transmission belt 1 9, the front surface of the frame 1 is fixedly connected to the motor 10, and the rear end of the output shaft of the motor 10 is fixedly connected to the center of the front surface of the transmission wheel 2 409 located in front of the storage box 301;

[0073] By starting the motor 10, the driving force of the driving wheel 1 203, the driving wheel 2 409, and the driving belt 1 9 can be used to control the rotation of the rotating rod 201 while driving the shaft 401 to rotate together, thereby realizing the joint driving operation of rotary tillage and sowing.

[0074] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
