Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0046] like Figures 1 to 8 As shown, this embodiment provides a planting device, which includes a workbench 100, a support 200, a pressing wheel 300, and a sowing assembly 400. The workbench 100 includes a parking area 110 and a receiving area 120, which are arranged side by side along the sowing direction. The receiving area 120 is provided with a receiving groove, in which a seedling tray 1000 can be placed. The pressing wheel 300 includes a wheel body and several pressing protrusions 320 evenly distributed around the outer periphery of the wheel body. The pressing wheel 300 is rotatably mounted on the support 200. The sowing assembly 400 is mounted on the support 200 and includes a sowing box 410 and a sowing wheel 420 located below the sowing port 411 of the sowing box 410. Several seed grooves 421 are evenly distributed around the periphery of the sowing wheel 420 for holding seeds.

[0047] In use, the support 200 can be moved from the parking area 110 to the receiving area 120, thereby moving the pressing wheel 300 from the parking area 110 to the seedling tray 1000 in the receiving area 120. Since the pressing wheel 300 includes pressing protrusions 320, when passing over the seedling tray 1000, it will press out several holes, i.e., pits, in the substrate soil in the seedling tray 1000. During the rotation of the sowing wheel 420 of the sowing component 400, the seeds can be transferred from the sowing port 411 to the seed trough 421 and then sown downwards into the holes, realizing the mechanical sowing action.

[0048] This planting device uses a pressing wheel 300 to press out holes in the substrate soil of the seedling tray 1000, creating several holes at a time, reducing labor intensity. Since the pressing wheel 300 includes a wheel body and pressing protrusions 320 on its outer periphery, and each pressing protrusion 320 is the same size, the depth and diameter of each hole are the same after pressing, which helps to cultivate seedlings of uniform height and improves seedling quality. Furthermore, the sowing wheel 420 in the sowing assembly 400 ensures uniform sowing, avoiding double sowing and missed sowing. The sowing process does not require human hand contact with the seeds, thus preventing seed contamination and improving seed germination rate.

[0049] In some embodiments, the pressure protrusions 320 are divided into several rows, and the rows of pressure protrusions 320 are evenly distributed around the axis of the wheel body, with each row of pressure protrusions 320 arranged along the axial direction of the wheel body. With this arrangement, the pressure wheel 300 can press out several acupoints in one rotation. Each row has ten pressure protrusions 320, for a total of twelve rows. That is, the pressure wheel 300 can press out 120 acupoints in one rotation.

[0050] In some embodiments, the wheel body includes a plurality of wheel units 310, which are coaxially arranged. A denting shaft 330 is mounted on the bracket 200, and the wheel units 310 pass through the denting shaft 330. The plurality of wheel units 310 are arranged side-by-side along the axial direction of the denting shaft 330, and dent protrusions 320 are located on the outer periphery of each wheel unit 310. This arrangement allows for individual replacement of the wheel unit 310 if a dent protrusion 320 is damaged, reducing maintenance costs. Each wheel unit 310 has twelve dent protrusions 320 on its outer periphery, and each wheel body includes ten wheel units 310.

[0051] Furthermore, the outer periphery of the wheel assembly 310 is provided with a fixing screw hole, and one end of the indentation protrusion 320 is provided with a fixing stud, which is screwed into the fixing screw hole. This structural design allows the indentation protrusion 320 to be replaced individually after damage, further reducing maintenance costs.

[0052] The wheel body also includes a spacer, which is located between any two wheel units 310. The spacer does not have a pressure pit protrusion 320. This structure allows for controllable number of holes pressed out per row, adapting to more application scenarios. In some embodiments, the pressure pit protrusion 320 in some of the fixing screw holes of the wheel unit 310 can be replaced with a filler stud. The length of the filler stud is shorter than the pressure pit protrusion 320, thus preventing the pressing out of holes in the seedling tray 1000 and avoiding the entry of substrate soil into the fixing screw holes.

[0053] The seed troughs 421 are arranged in several rows, evenly distributed around the axis of the sowing wheel 420; each row of seed troughs 421 is arranged along the axial direction of the sowing wheel 420, and the number of seed troughs 421 in each row is the same as the number of pressing pit protrusions 320 in each row. Specifically, there are four rows of seed troughs 421, with ten in each row. The axial spacing of the seed troughs 421 matches the axial spacing of the pressing pit protrusions 320. The circumferential spacing of the seed troughs 421 matches the circumferential spacing of the pressing pit protrusions 320.

[0054] In some embodiments, the planting device includes a transmission assembly connected between the pressing wheel 300 and the sowing wheel 420. The pressing wheel 300 can drive the sowing wheel 420 to rotate via the transmission assembly. Specifically, the transmission assembly includes a drive wheel 510, a driven wheel 520, and a chain 530. The drive wheel 510 and the pressing wheel 300 are coaxially fixed, the driven wheel 520 and the sowing wheel 420 are coaxially fixed, and the chain 530 is wound between the drive wheel 510 and the driven wheel 520. This structure allows the rotation of the pressing wheel 300 to drive the sowing wheel 420, achieving synchronous rotation and improving the accuracy and uniformity of sowing. Both the drive wheel 510 and the driven wheel 520 are sprockets. The transmission ratio between the drive wheel 510 and the driven wheel 520 can be 1:1.

[0055] An overrunning clutch is provided inside the drive wheel 510, which cuts off the power to the sowing wheel 420 when the pressure wheel 300 reverses, thus stopping sowing. The structure of the overrunning clutch is well known to those skilled in the art and is not the focus of this application, so it will not be described in detail here.

[0056] In this embodiment, the pressing wheel 300 rotates once, and the sowing wheel 420 rotates once, so that one seed is sown every two holes in the sowing direction. Since the pressing wheel 300 is cylindrical, if the number of rows of pressing protrusions 320 is too small, it will not form a stable support structure, reducing the smoothness of the pressing wheel 300's rotation. Therefore, in this embodiment, the number of holes is three times the number of seeds sown. The extra holes provide greater friction for the rotation of the pressing wheel 300, improving the smoothness of its rotation.

[0057] Of course, in other embodiments, the ratio between the drive wheel 510 and the driven wheel 520 can be set so that the pressing wheel 300 rotates once and the sowing wheel 420 rotates three times, thereby sowing one seed in each hole.

[0058] In some embodiments, the workbench 100 is provided with a support leg 130 on its lower side. The planting device includes a drive assembly 700 and a pressure adjustment assembly 600. The pressure adjustment assembly 600 is disposed on the support 200, and the drive assembly 700 is disposed on the pressure adjustment assembly 600 and is used to drive the pressure adjustment assembly 600 to move along the sowing direction, and to drive the support 200 to move between the parking area 110 and the receiving area 120. This structure enables the support 200 to move automatically, improving the degree of automation and increasing sowing efficiency.

[0059] The pressure adjustment assembly 600 includes a connecting rod 610, an elastic element 620, an adjustment base 630, and a pressure adjustment nut 640. The bracket 200 is provided with a ballast part 210, which has a ballast hole. The connecting rod 610 passes through the ballast hole. One end of the connecting rod 610 is located below the worktable 100 and is connected to the adjustment base 630. The other end of the connecting rod 610 passes through the ballast hole and is screwed to the pressure adjustment nut 640. The elastic element 620 is located between the ballast part 210 and the pressure adjustment nut 640 and is used to apply a downward force to the ballast part 210. The drive assembly 700 includes a drive element 710 and a roller 720. The roller 720 abuts against the lower side of the worktable 100. The drive element 710 is located on the adjustment base 630 and is drively connected to the roller 720. The aforementioned structure causes the support 200 to be subjected to pressure from the elastic element 620, thereby transmitting the pressure to the indentation wheel 300. The varying elastic forces applied during the indentation process result in different indentation depths. The other end of the connecting rod 610 is provided with a trapezoidal thread. The elastic element 620 includes a spring, which is sleeved on the connecting rod 610, with its two ends abutting against the pressure adjusting nut 640 and the ballast part 210, respectively.

[0060] The drive unit 710 is a dual-shaft motor, and two rollers 720 are provided, each mounted on one of the two output shafts of the motor. The two rollers 720 are located on opposite sides of the worktable 100 in the width direction, perpendicular to the sowing direction. The arrangement of the two rollers 720 makes the movement of the support 200 more stable. The rollers 720 are rubber wheels.

[0061] The workbench 100 has a traveling surface along which the rollers 720 roll. There are two traveling surfaces, positioned between the two rollers 720. The two traveling surfaces converge from top to bottom towards the center, forming a V-shape with the rollers 720. This arrangement ensures that the rollers 720 can only move in the sowing direction, not in the width direction of the workbench 100, and cannot move upwards, thus guaranteeing the stability of the support 200 and preventing it from slipping off the workbench 100.

[0062] In some embodiments, the pressure pit protrusion 320 has a frustum-shaped structure. Specifically, the diameter of the pressure pit protrusion 320 gradually decreases along the direction away from the wheel body. This shape arrangement makes the pressed acupoints open upwards in a funnel shape, which facilitates seed sowing and also makes it easier for the pressure pit protrusion 320 to be withdrawn from the acupoint.

[0063] In some embodiments, the ballast portion 210 is plate-shaped. There are two ballast portions 210, and four connecting rods 610 and four elastic members 620 are provided. The two connecting rods 610 form a group and are located at both ends of the ballast portion 210. The elastic members 620 and the connecting rods 610 are arranged in a one-to-one correspondence.

[0064] In this embodiment, because the pressing wheel 300 has a certain width in the sowing direction, that is, the diameter of the pressing wheel 300 is relatively large, the seeds can only be transported to the lower side of the axis of the pressing wheel 300 through the sowing hose 440. If the sowing hose 440 is not used, the seeds can only leak to the rear side of the pressing wheel 300 in the forward direction, resulting in some seeds not being able to enter the planting hole.

[0065] Therefore, in this embodiment, the sowing assembly 400 includes a sowing housing 430, a sowing hose 440, and a sowing adjustment assembly 450. The sowing housing 430 is located below the sowing box 410 and has an upper opening and a lower opening. The upper opening communicates with the sowing port 411, and the lower opening communicates with the inlet end of the sowing hose 440. The sowing adjustment assembly 450 is connected between the support 200 and the sowing hose 440 and is used to adjust the position of the outlet end of the sowing hose 440. The sowing wheel 420 is rotatably mounted on the sowing housing 430. The sowing housing 430 and the seed trough 421 form a receiving cavity for accommodating seeds. The sowing shaft 467 is rotatably mounted in the sowing housing 430, and both the driven wheel 520 and the sowing wheel 420 are fixedly connected to the sowing shaft 467. This arrangement makes the distance between the outlet end of the sowing hose 440 and the pressing wheel 300 adjustable, thereby enabling the seeds to be accurately sown into the planting holes and improving the sowing accuracy. The seeds enter the receiving cavity through the upper opening and the sowing tube 440 through the lower opening.

[0066] Because the pressing wheel 300 and the sowing wheel 420 rotate synchronously, the first seed begins to fall after the first hole is pressed out, and the first seed lands exactly in the first hole after the second hole is pressed out. Alternatively, the sowing wheel 420 can be configured to release one seed for every three holes pressed out, meaning the number of seed grooves 421 on one circumference of the sowing wheel 420 is one-third the number of pressing protrusions 320 on one circumference of the wheel body. Combined with the structure where the outlet end of the sowing hose 440 is located behind the axis of the pressing wheel 300, the seed will land exactly in the 3nth hole, where n is a positive integer, meaning the seed lands in the third hole, the sixth hole, and so on.

[0067] Regarding the specific structure of the seeding adjustment assembly 450, in some embodiments, the seeding adjustment assembly 450 includes a pipe clamp 451, a seeding adjustment screw 452, and a seeding adjustment nut. One end of the pipe clamp 451 is connected to the seeding hose 440, and the other end is rotatably engaged with one end of the seeding adjustment screw 452. The seeding adjustment nut is fixed to the bracket 200 and threadedly engaged with the seeding adjustment screw 452. This structure allows the rotation of the seeding adjustment screw 452 to adjust the position of the seeding hose 440 with high precision.

[0068] Specifically, the pipe clamp 451 includes a pipe installation part 4511 and a pipe adjustment part connected together. The pipe installation part 4511 has a pipe channel through which the sowing hose 440 passes. The pipe adjustment part includes an adjustment rod 4512 and an adjustment cap 4513 screwed to the adjustment rod 4512. The bottom of the adjustment cap 4513 has a through hole. One end of the sowing adjustment screw 452 has a stop plate 4521. The sowing adjustment screw 452 passes through the through hole, and the stop plate 4521 is clamped between the bottom of the adjustment rod 4512 and the adjustment cap 4513. The pipe adjustment part is slidably mounted on the support 200 along the sowing direction. The adjusting cap 4513 includes an adjusting tube and a sealing element located at one end of the adjusting tube. A through hole is located in the sealing element. The inner wall of the adjusting tube has internal threads, and the outer circumference of the adjusting rod 4512 has external threads. The adjusting tube and the adjusting rod 4512 are screwed together. A stop plate 4521 is clamped between the adjusting rod 4512 and the sealing element. This arrangement allows the sowing adjusting screw 452 to adjust the outlet end of the sowing hose 440 towards or away from the pressure roller 300 via the stop plate 4521. The diameter of the stop plate 4521 is larger than the diameter of the through hole, but smaller than the inner diameter of the adjusting tube.

[0069] To facilitate manual adjustment, in some embodiments, the seeding adjustment assembly 450 includes a handwheel 4522, which is located at the other end of the seeding adjustment screw 452. The seeding adjustment screw 452 has a trapezoidal thread.

[0070] The seeding wheel 420 is coaxially connected to the seeding drive wheel 466. The seeding assembly 400 includes a vibrating plate 461, a vibrating shaft 462, a vibrating driven wheel 463, a transmission belt 464, and a vibrating eccentric wheel 465. One end of the vibrating plate 461 is hinged to the bottom of the seeding box 410, and the other end of the vibrating plate 461 is flexibly connected to the seeding box 410. The vibrating shaft 462 is rotatably located on the outside of the seeding box 410. The vibrating eccentric wheel 465 is located on the vibrating shaft 462 and abuts against the vibrating plate 461. The vibrating driven wheel 463 is located on the vibrating shaft 462. The transmission belt 464 is wound between the seeding drive wheel 466 and the vibrating driven wheel 463. The vibrating plate 461 is located inside the seeding box 410. This arrangement allows the seeds to be supported by the vibrating plate 461. As the sowing wheel 420 rotates, it drives the sowing drive wheel 466 to rotate, which in turn drives the vibrating eccentric wheel 465 to rotate. This causes the vibrating plate 461 to oscillate back and forth around the hinge axis, allowing the seeds to fall smoothly. The sowing drive wheel 466 is mounted on the sowing shaft 467.

[0071] In some embodiments, multiple vibrating eccentric wheels 465 are provided, and during the rotation of the vibrating shaft 462, the multiple vibrating eccentric wheels 465 sequentially abut against the vibrating plate 461. This arrangement results in a higher vibration frequency of the vibrating plate 461. The number of vibrating eccentric wheels 465 is 3-10. The smaller the seed size, the more vibrating eccentric wheels 465 are used; the larger the seed size, the fewer vibrating eccentric wheels 465 are used. In some embodiments, when the outer diameter of the seed is less than 5 mm, ten vibrating eccentric wheels 465 are provided. In some embodiments, when the outer diameter of the seed is greater than 10 mm, three vibrating eccentric wheels 465 are provided. In some embodiments, when the outer diameter of the seed is greater than 8 mm, four vibrating eccentric wheels 465 are provided.

[0072] The protruding points of multiple vibrating eccentric wheels 465 are unevenly arranged around the vibrating shaft 462. In other words, the frequency at which the multiple vibrating eccentric wheels 465 strike the vibrating plate 461 is variable; that is, during the uniform rotation of the vibrating shaft 462, two different time intervals are generated between the three vibrating eccentric wheels 465 striking the vibrating plate 461. With the above arrangement, the vibrating plate 461 can vibrate seeds of different sizes.

[0073] The vibrating eccentric wheel 465 can be detachably fixed to the vibrating shaft 462 by means of locking screws. The method of fixing the vibrating eccentric wheel 465 is well known to those skilled in the art, and will not be described in detail here.

[0074] The seeding drive wheel 466 is located outside the seeding housing 430 and is fixedly connected to the seeding shaft 467.

[0075] The vibrating plate 461, vibrating shaft 462, vibrating driven wheel 463, transmission belt 464, and vibrating eccentric wheel 465 form a vibrating assembly. The seeding box 410 is a funnel-shaped structure composed of four flat plates. Two sets of vibrating assemblies are provided, each set positioned on two opposite flat plates. In this embodiment, the seeding drive wheel 466 has two grooves, and two transmission belts 464 are wound around the two grooves respectively.

[0076] In some embodiments, the plate may have weight-reducing holes, and one end of the vibrating plate 461 is rotatably mounted on the side wall of the weight-reducing hole near the seeding opening 411, while the other end is connected to the side wall of the weight-reducing hole away from the seeding opening 411 via a flexible member. The flexible member may be a rubber sheet or a cloth sheet.

[0077] The top surface of the parking area 110 is flush with the top surface of the seedling tray 1000; the pressing wheel 300 can roll within both the parking area 110 and the seedling tray 1000. This arrangement facilitates the transfer of the pressing wheel 300 between the two areas. Furthermore, the pressing protrusion 320 of the pressing wheel 300 also functions as a climbing structure, allowing the pressing wheel 300 to easily move from a lower position in the seedling tray 1000 to a higher position in the parking area 110.

[0078] In some embodiments, a guide rail 140 is provided on the lower side of the worktable 100, and a guide rod is provided on the adjusting base 630. A guide wheel 730 is rotatably provided at the other end of the guide rod, and the guide wheel 730 rolls along the guide rail 140. The detection element 150 is provided at both ends of the guide rail 140 and can be triggered by the guide wheel 730.

[0079] In some embodiments, the workbench 100 is provided with two detection elements 150, which are respectively located at both ends of the workbench 100. When the pressing wheel 300 is located in the parking area 110, the detection element 150 detects the guide wheel 730 located in the first position. When the pressing wheel 300 is located in the receiving area 120 and the pressing of the entire seedling tray 1000 is completed, the detection element 150 detects the guide wheel 730 located in the second position. The detection element 150 can be a limit switch. The detection element 150 is communicatively connected to the controller. When the detection element 150 detects the guide wheel 730 located in the first position, the controller controls the drive element 710 to stop, facilitating the replacement of the seedling tray 1000.

[0080] The planting device also includes an auxiliary wheel 800, which is rotatably mounted on the support 200 and is spaced apart from the pressing wheel 300 along the sowing direction.

[0081] The working principle is as follows: The seedling tray 1000 is placed on the workbench 100, and the support 200 is placed at the starting point of the workbench 100, i.e., the guide wheel 730 is in the first position. Depending on the type of seed, the pressure adjusting nut 640 is adjusted to change the preload, resulting in different depths of the seed holes. Seeds are added into the sowing box 410. The handwheel 4522 is adjusted, and under the action of the sowing adjusting screw 452, the pipe clamp 451 changes position, driving the sowing hose 440 to move, thereby changing the position of the outlet end of the sowing hose 440 and the pressure roller 300. Spacing; After completing the preparation work, start the dual-shaft motor. Under the action of the rolling wheel 720, drive the adjusting base 630 to move below the workbench 100. The pressing wheel 300 is forced to rotate, pressing out indentations on the seedling tray 1000. The pressing wheel 300 drives the transmission drive wheel 510 to rotate. The transmission drive wheel 510 drives the transmission driven wheel 520 to rotate through the transmission chain 530. The transmission driven wheel 520 drives the sowing shaft 467 to rotate. The sowing shaft 467 drives the sowing wheel 420 to rotate. The sowing shaft 467 evenly discharges the seeds. The sowing shaft 467 drives the sowing drive wheel 466 to rotate. Through the transmission belt 464, it drives the vibrating driven wheel 463 to rotate. The vibrating driven wheel 463 drives the vibrating shaft 462 to rotate, thereby driving the vibrating eccentric wheel 465 to rotate. The vibrating eccentric wheel 465 vibrates the vibrating plate 461. The vibrating plate 461 vibrates the seeds in the sowing box 410, causing them to fall evenly.
