[0001] This application belongs to the field of agricultural product planting technology, specifically relating to a seeding device for plant planting. Background Technology

[0002] Sowing is part of the agricultural product planting process, and existing technologies divide it into two methods: direct sowing and hill sowing. Direct sowing involves evenly scattering seeds on cultivated land and then smoothing it with a roller to ensure that the seeds can develop normally.

[0003] The inventors discovered that existing seeding devices can only disperse seeds and cannot smooth the seeding surface, resulting in reduced seeding efficiency. Utility Model Content

[0008] A seed-distributing assembly is fixedly mounted at the front end of the chassis for holding seeds and discharging seeds toward the gap space;

[0009] A lifting component is slidably connected to the chassis in the vertical direction, and has a locking structure between it and the chassis; and

[0010] A pressure roller is disposed on the lower side of the chassis, its axis is parallel to the left and right direction, and the pressure roller is rotatably connected to the lifting component in the left and right direction;

[0011] The pressure roller is located behind the seeding assembly. When the locking structure connects the lifting component and the chassis, the pressure roller can avoid the seeding surface or roll on the seeding surface.

[0012] In one possible implementation, the chassis has two guide holes arranged side-by-side in the left-right direction and both penetrating in the up-down direction, and the lifting component includes:

[0013] A lifting platform is disposed above the chassis and extends in the left-right direction; and

[0014] Two connecting plates are fixedly connected to both ends of the lifting plate, and both extend downwards to pass through the two guide holes and protrude.

[0015] The pressure roller is disposed between the two connecting plates, and its two ends are respectively rotatably connected to the two connecting plates in the left and right directions.

[0016] In one possible implementation, the locking structure includes:

[0017] A positioning hole is formed on the lifting plate and extends through it in the vertical direction;

[0018] A positioning block is disposed between the lifting plate and the chassis, and is slidably connected to the chassis in a front-to-back direction; the positioning block has a first mating groove adapted to communicate with the positioning hole; the positioning block has an upwardly extending protrusion, and the upper end surface of the protrusion has a second mating groove adapted to communicate with the positioning hole; and

[0019] A locking rod is slidably inserted into the positioning hole and is adapted to be inserted into the first docking groove or the second docking groove so that the alignment block supports the lifting plate and restricts the alignment block from moving in the front-back direction;

[0020] When the locking rod is inserted into the first docking groove, the pressure roller is adapted to be supported on the ground; when the locking rod is inserted into the second docking groove, the pressure roller is positioned above the support surface.

[0021] In one possible implementation, both ends of the alignment block have upwardly extending limiting portions adapted to abut against the lifting plate.

[0022] In one possible implementation, the locking structure has two sets, with the two alignment blocks connected by a first linkage plate and the two locking rods connected by a second linkage plate.

[0023] In one possible implementation, the lower side of the lifting plate is provided with a groove that runs through the front and rear direction, and the positioning hole communicates with the groove; the rear edge of the bottom of the groove is chamfered, and the front side of the protrusion is an inclined surface from top to bottom towards the front, so that when the alignment block moves forward and the front side of the protrusion contacts the chamfered structure, the lifting plate can move upward.

[0024] In one possible implementation, a concave ball groove is formed on the inner wall of the guide hole, and a ball is disposed in the concave ball groove; a portion of the ball extends out of the concave ball groove, and a strip-shaped groove extending in the vertical direction is formed on the connecting plate, which is suitable for the extended portion of the ball to be embedded.

[0025] In one possible implementation, the chassis has a discharge port extending vertically, and the dispersing assembly includes:

[0026] A storage tank is mounted on the chassis and connected to the upper side of the chassis via a bracket; the storage tank has a hollow interior and gradually tapers from top to bottom, with its lower end extending through the discharge port; the lower end of the storage tank has an open structure and is connected to a filter screen; furthermore, the rear side of the storage tank has a through hole communicating with its interior; and

[0027] The baffle is slidably connected to the chassis in the front-to-back direction, and is driven by a linear drive cylinder for moving it in the front-to-back direction.

[0028] The linear drive cylinder can drive the baffle to insert into the through hole; when the baffle is inserted into the through hole, the left and right sides of the baffle are respectively in contact with the inner wall of the storage box to separate the inner cavity of the storage box and restrict the downward movement of the seeds.

[0029] In one possible implementation, a recessed groove is provided on the inner wall of the storage tank; the recessed groove is oriented toward the through hole and is adapted for the baffle to be embedded in.

[0030] In one possible implementation, the upper side of the chassis is fixedly connected to two vertical plates arranged side by side in the left-right direction. Each vertical plate is hinged with a swing arm in the left-right direction, and the two swing arms have a grip bar connected to their swing ends for the operator to hold, as well as a plurality of reinforcing parts with an X-shaped cross section.

[0031] In this embodiment, the chassis can be moved horizontally by being supported on the ground by rollers, creating a gap between the chassis and the ground. Based on this, the seeding component can input seeds into the gap at the front end of the chassis and let them fall onto the ground. Subsequently, by adjusting the position of the lifting component and connecting the lifting component and the chassis through a locking structure, the vertical position of the pressure roller can be adjusted, thereby achieving two settings: the pressure roller touching the ground or avoiding the ground. This enables a single seeding operation mode or a simultaneous seeding and roller pressing operation mode.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0048] Please refer to the following: Figures 1 to 9 The plant sowing device provided in this application will now be described. The plant sowing device proposed in this application includes a chassis 1, a sowing component 2, a lifting component 3, and a pressure roller 4.

[0049] The chassis 1 has multiple rollers 11 on its lower side, and these rollers 11 are rotatably connected to the lower side of the chassis 1 in the left-right direction; in this embodiment, there are four rollers 11, which are respectively arranged at the four corners of the chassis 1.

[0050] In actual use, the chassis 1 is supported on the ground by rollers 11 so that it can travel in a horizontal direction, and a gap space is formed between its lower side and the ground.

[0051] The seeding component 2 is fixedly installed at the front end of the chassis 1 and is used to hold seeds and quantitatively discharge seeds toward the gap space. It should be noted that, in one embodiment, the seeding component 2 has the ability to hold different seeds and discharge the corresponding seeds as needed; that is, when the seeding component 2 is used, it has the ability to sow multiple types of seeds.

[0052] The lifting component 3 is slidably connected to the chassis 1 in the vertical direction, and there is a locking structure 5 between the lifting component 3 and the chassis 1 for connecting the lifting component 3 and the chassis 1.

[0053] The pressure roller 4 is located on the lower side of the chassis 1, with its axis parallel to the left and right directions, and the pressure roller 4 is rotatably connected to the lifting component 3 in the left and right directions.

[0054] In this embodiment, the pressure roller 4 is located behind the spreading assembly 2; therefore, when the lifting member 3 and the chassis 1 are connected by the locking structure 5, the pressure roller 4 can avoid the sowing surface or roll on the sowing surface.

[0055] In this embodiment, the chassis 1 can be moved horizontally by being supported on the ground by the rollers 11, creating a gap between the chassis 1 and the ground. Based on this, the seeding component 2 can input the seeds into the gap and let them fall on the ground from the front end of the chassis 1. Then, by adjusting the position of the lifting component 3 and connecting the lifting component 3 and the chassis 1 by the locking structure 5, the vertical position of the pressure roller 4 can be adjusted, thereby achieving two settings: the pressure roller 4 touching the ground or avoiding the ground, so as to realize the operation mode of seeding alone, or the operation mode of seeding and pressing at the same time.

[0056] The plant planting device provided in this embodiment, compared with the prior art, can realize automatic leveling and soil backfilling after sowing, ensuring the stability of sowing efficiency.

[0057] In some embodiments, such as Figure 1 , Figure 4 and Figure 6 As shown, the chassis 1 has two guide holes 12 arranged side by side in the left-right direction and both extending in the up-down direction; based on this, the lifting component 3 includes a lifting plate 31 and two connecting plates 32.

[0058] The lifting plate 31 is positioned above the chassis 1 and extends in the left and right directions.

[0059] Two connecting plates 32 are fixedly connected to both ends of the lifting plate 31, and both extend downwards to pass through the two guide holes 12 and protrude.

[0060] The pressure roller 4 is positioned between two connecting plates 32, and its two ends are respectively rotatably connected to the two connecting plates 32 in the left and right directions.

[0061] In some embodiments, such as Figure 7 As shown, the locking structure 5 includes a positioning hole 51, an alignment block 52, and a locking rod 53.

[0062] The positioning hole 51 is provided on the lifting plate 31 and extends through it in the vertical direction.

[0063] Alignment block 52 is disposed between lifting plate 31 and chassis 1, and is slidably connected to chassis 1 in the front-rear direction; alignment block 52 is provided with a first docking groove 521 suitable for communicating with positioning hole 51; alignment block 52 has an upwardly extending protrusion 522, and the upper end surface of protrusion 522 is provided with a second docking groove 5221 that is also suitable for communicating with positioning hole 51.

[0064] In other words, as the alignment block 52 moves along the front and rear direction, both the first docking groove 521 and the second docking groove 5221 can communicate with the positioning hole 51. Compared with the first docking groove 521 communicating with the positioning hole 51, when the second docking groove 5221 communicating with the positioning hole 51, the lifting plate 31 is at a higher position due to the presence of the protrusion 522.

[0065] The locking rod 53 is slidably inserted into the positioning hole 51 and is adapted to be inserted into the first docking groove 521 or the second docking groove 5221 so that the alignment block 52 supports the lifting plate 31 and restricts the alignment block 52 from moving in the front-back direction.

[0066] By adopting the above technical solution, when the locking rod 53 is inserted into the first docking groove 521, the pressure roller 4 is supported on the ground; when the locking rod 53 is inserted into the second docking groove 5221, the pressure roller 4 is set higher than the support surface.

[0067] In some embodiments, such as Figure 3 As shown, both the front and rear ends of the alignment block 52 have upwardly extending limiting portions 523 adapted to abut against the lifting plate 31, so as to limit the extreme position of the alignment block 52 relative to the lifting plate 31 in the front-rear direction.

[0068] In some embodiments, such as Figure 3 As shown, the locking structure 5 has two sets, and the two alignment blocks 52 are connected by the first linkage plate 10, and the two locking rods 53 are connected by the second linkage plate 20.

[0069] In actual use, the user can control the movement of the alignment block 52 by pushing the first linkage plate 10 forward with their foot; at the same time, lifting the second linkage plate 20 upward will allow the two locking rods 53 to be pulled out simultaneously.

[0070] In some embodiments, such as Figure 7 As shown, the lower side of the lifting plate 31 has a groove 311 that runs through the front and rear direction, and the aforementioned positioning hole 51 is connected to this groove 311.

[0071] The rear edge of the groove bottom of the groove 311 adopts a chamfered structure, and the front side of the protrusion 522 adopts an inclined surface from top to bottom towards the front.

[0072] By adopting the above technical solution, when the alignment block 52 moves forward and the front side of the protrusion 522 contacts the chamfered structure, the lifting plate 31 can be squeezed and move upward.

[0073] In some embodiments, such as Figure 5 and Figure 6 As shown, a concave ball groove 121 is provided on the inner wall of the guide hole 12, and a ball bearing 122 is provided in the concave ball groove 121.

[0074] Among them, some of the balls 122 extend out of the concave ball groove 121, and the connecting plate 32 is provided with a strip groove 321 extending in the vertical direction and suitable for the ball 122 to be inserted, so as to optimize the sliding of the connecting plate 32 in the guide hole 12.

[0075] In some embodiments, such as Figure 3 , Figure 4 and Figure 8 As shown, the chassis 1 has a discharge port 13 that runs through the vertical direction; based on this, the dispersing component 2 includes a storage box 21 and a baffle 22.

[0076] The storage bin 21 is mounted on the chassis 1 and connected to the upper side of the chassis 1 via a bracket 14; specifically, the bracket 14 is fixedly mounted on the chassis 1 and supported on the side of the storage bin 21.

[0077] The storage bin 21 has a hollow interior and gradually shrinks from top to bottom, with its lower end extending through the discharge port 13. The lower end of the storage bin 21 has an open structure and is connected to a filter screen 211 that allows seeds to pass through while restricting the passage of impurities.

[0078] The rear side of the storage tank 21 has a through hole 212 communicating with its interior; the baffle 22 is slidably connected to the chassis 1 in the front-back direction, and is adapted to be inserted into the storage tank 21 through the through hole 212 and is connected to a linear drive cylinder 221 for driving it to move in the front-back direction.

[0079] In actual use, the linear drive cylinder 221 can drive the baffle 22 to insert into the through hole 212; and when the baffle 22 is inserted into the through hole 212, the left and right sides of the baffle 22 are respectively connected to the inner wall of the storage box 21 to separate the inner cavity of the storage box 21 and restrict the seeds from moving downward.

[0080] In some embodiments, such as Figure 3 and Figure 9As shown, a recessed groove 213 is provided on the inner wall of the storage tank 21. This recessed groove 213 is positioned towards the through hole 212 and is suitable for the baffle 22 to be inserted to eliminate the gap between the baffle 22 and the inner front wall of the storage tank 21.

[0081] In some embodiments, such as Figure 1 As shown, the upper side of the chassis 1 is fixedly connected to two vertical plates 15 arranged side by side in the left-right direction. Each vertical plate 15 is hinged with a swing arm 6 in the left-right direction. The two swing arms 6 have a grip bar 61 connected to their swing ends for the operator to hold, and multiple reinforcing parts 62 with an X-shaped cross section.

[0082] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
