Abstract

The present application relates to the technical field of agricultural equipment, and specifically provides an automatic soil filling and bagging device for south medicine seedling production, which comprises a rack, a rotating disc, a plurality of filler assemblies and a feeding hopper. The axis of the rotating disc is horizontal and is rotatably connected to the rack. The filler assemblies are circumferentially and equidistantly arranged on the rotating disc. Each filler assembly comprises a filler cylinder, a clamping jaw and a driving member. The axis of the filler cylinder coincides with the diameter line of the rotating disc. The device is provided with filler assemblies, and each filler assembly comprises a clamping jaw. When the gravity of the soil in the soil bag increases to be greater than the friction between the soil bag and the clamping jaw, the soil bag automatically separates from the clamping jaw. Compared with the filling method of the existing auger feeder, the present application can control the filling amount in the soil bag. Therefore, the consistency of the soil weight in each soil bag after filling is better, and manual flattening or supplementing of the soil in the soil bag is not required subsequently. Therefore, the present application can improve the filling efficiency.

Description

Technical Field

[0001] This invention relates to the field of agricultural equipment technology, and in particular to an automatic soil-filling and bagging device for the production of southern medicinal herb seedlings. Background Technology

[0002] Southern medicinal herbs, also known as Lingnan characteristic Chinese medicinal materials, include but are not limited to cinnamon, Morinda officinalis, and Amomum villosum, among other Lingnan characteristic medicinal materials.

[0003] For the production of seedlings of southern medicinal herbs, the mainstream cultivation method is currently container seedling raising. This involves first filling soil bags with the soil needed for seedling raising, and then planting the seedlings in the soil inside the bags. The advantage of this method is that the entire root ball can be moved to the field together during transplanting, eliminating the need for a recovery period and resulting in a high survival rate. Therefore, it has become the mainstream cultivation method.

[0004] To fill soil into soil bags, the common method is to place multiple soil bags side by side with their openings facing upwards. Then, a screw conveyor feeds the soil to the top of the soil bags, allowing it to fall naturally into the bags, thus completing the filling process.

[0005] However, the above-mentioned filling method has the following drawbacks: the auger feeder has difficulty in evenly distributing the soil into each soil bag, soil bags that overflow need to be smoothed out manually, and soil bags that are not full need to be replenished manually. Therefore, the filling efficiency of the soil is low. Summary of the Invention

[0006] Therefore, it is necessary to provide an automatic soil filling and bagging equipment for the production of southern medicinal herb seedlings to address the problems existing in the current soil bagging process and solve the problem of low soil filling efficiency.

[0007] The above objectives are achieved through the following technical solutions: An automatic soil-filling and bagging device for producing seedlings of southern medicinal herbs is used to fill soil bags with soil material, including: frame; The rotating disk has a horizontal axis and is rotatably connected to the frame; There are multiple packing assemblies, which are circumferentially spaced on the rotating disk; The packing assembly includes a packing cylinder, grippers, and a drive unit. The axis of the packing cylinder coincides with the radial line of the rotating disk, and the packing cylinder is fixed on the rotating disk. Both ends of the packing cylinder are open. There are multiple grippers, which are circumferentially spaced at equal intervals on the outer periphery of the packing cylinder. The drive unit is used to drive the multiple grippers to move simultaneously along the radial direction of the packing cylinder. The packing assembly has a bagging station and a packing station in the circumferential direction; When the filling assembly rotates to the bagging station and the soil bag is placed outside the gripper, the drive unit moves the gripper radially outward from the first position to the second position to tension the soil bag. When the packing assembly rotates to the packing position and the soil bag disengages from the gripper, the drive unit causes the gripper to return to the first position radially inward, at which point multiple grippers circumferentially converge. The feeding hopper is used to allow the soil inside the packing cylinder to fall into the packing cylinder after the packing cylinder rotates to the packing position.

[0008] Furthermore, the driving component includes a rocker arm, a sliding ring, a cantilever, and an electromagnetic telescopic rod. The axis of the electromagnetic telescopic rod is parallel to the axis of the packing cylinder. The housing of the electromagnetic telescopic rod is fixed on the rotating disk. The cantilever is fixedly connected to the telescopic end of the electromagnetic telescopic rod. The sliding ring is fixedly connected to the cantilever and is slidably sleeved on the outside of the packing cylinder. One end of the rocker arm is rotatably connected to the sliding ring, and the other end is rotatably connected to the gripper. The middle part of the gripper is rotatably connected to the packing cylinder.

[0009] Furthermore, the drive component also includes guide rods and elastic elements. There are multiple guide rods, which are spaced apart and fixed on the rotating disk. The guide rods are slidably connected to the cantilever. The elastic elements are sleeved on the outside of the guide rods and are configured to prevent the sliding ring from moving toward the center of the rotating disk.

[0010] Furthermore, the packing assembly also includes a flexible cylinder, which is coaxially fixed to the bottom of the packing cylinder; When the gripper is in the first position, the gripper squeezes the flexible cylinder inward until the port of the flexible cylinder is in a gathered state.

[0011] Furthermore, the flexible cylinder is made of either polyethylene plastic or polypropylene plastic.

[0012] Furthermore, a spring-loaded ring is provided on the inner circumferential surface of the flexible cylinder.

[0013] Furthermore, a wear-resistant part is provided on the outer circumferential surface of the flexible cylinder at a position corresponding to the gripper.

[0014] Furthermore, a collection hopper is provided at intervals directly above the feeding hopper, and the two ends of the collection hopper are connected to collect the soil falling from the filling cylinder and return the soil to the feeding hopper.

[0015] Furthermore, an automatic soil-filling and bagging device for producing southern medicinal herb seedlings also includes a pneumatic carrier for supporting the soil-filled bags after they have detached from the grippers and transporting the soil-filled bags to a designated location.

[0016] Furthermore, an automatic soil-filling and bagging device for the production of southern medicinal herb seedlings also includes a track trolley with a material bucket on it for collecting and transporting soil bags to a designated location.

[0017] The beneficial effects of this invention are: 1. This invention includes a filling assembly comprising grippers. When the weight of the soil in the filling bag increases to exceed the frictional force between the filling bag and the grippers, the filling bag automatically detaches from the grippers. Compared to the filling method of existing auger feeders, this invention can control the amount of filling material in the filling bags. Therefore, the consistency of soil weight in each filling bag after filling is better. Furthermore, after the filling bag detaches from the grippers, the grippers automatically converge circumferentially to prevent the soil from falling further, thus avoiding excessive soil in the filling bags. Therefore, there is no need for manual leveling or replenishment of the soil in the filling bags afterward. Thus, this invention can improve filling efficiency.

[0018] 2. This invention includes a filling assembly comprising a flexible cylinder. During filling, the flexible cylinder prevents soil from spilling from the gap between the soil bag and the filling cylinder. After the soil bag detaches from the gripper, the gripper swings from a second position to a first position. At this time, the first gripper presses the flexible cylinder inward, causing the lower end of the flexible cylinder to be compressed inward and converged, thus preventing the soil inside from spilling out. When the filling assembly swings upward above the collecting hopper, the soil inside falls back into the collecting hopper under its own gravity, thereby replenishing the soil in the feeding hopper and preventing the soil bag from failing to fall due to insufficient soil falling into it.

[0024] The following reference Figures 1-8 This invention describes an automatic soil-filling and bagging device for the production of southern medicinal herb seedlings.

[0025] An automatic soil-filling and bagging device for the production of southern medicinal herb seedlings is used to fill soil into soil bags 900, the shape of which is as follows: Figure 8 As shown, a cup-shaped, wider at the top and narrower at the bottom automatic soil-filling and bagging device for producing southern medicinal herb seedlings includes a frame 100, a rotating disk 200, a filling assembly 300, and a feeding hopper 400. The axis of the rotating disk 200 is horizontal and rotatably connected to the frame 100. Multiple filling assemblies 300 are arranged circumferentially at equal intervals on the rotating disk 200. Each filling assembly 300 includes a filling cylinder 310, grippers 320, and a driving component 330. The axis of the filling cylinder 310 coincides with the radial line of the rotating disk 200. The packing cylinder 310 is fixed on the rotating disk 200, and both ends of the packing cylinder 310 are open. Multiple grippers 320 are circumferentially spaced around the outer periphery of the packing cylinder 310. A driving component 330 drives the multiple grippers 320 to move simultaneously radially along the packing cylinder 310. The packing assembly 300 has a bagging station and a packing station on the circumference of the rotating disk 200. The packing station is the station when the packing assembly 300 rotates to its lowest position. At this position, the axis of the packing cylinder 310 in the packing assembly 300 is vertical. Figure 3 The position corresponding to Q1 in the diagram is the bagging station, located behind the movement trajectory of the rotary disc 200 and adjacent to the filling station. Figure 3 At position Q2, when the filling assembly 300 rotates to the bagging station and the soil bag 900 is fitted onto the outside of the gripper 320, the drive unit 330 moves the gripper 320 radially outward from the first position to the second position to tension the soil bag 900. When the filling assembly 300 rotates to the filling station and the soil bag 900 disengages from the gripper 320, the drive unit 330 resets the gripper 320 radially inward to the first position. At this time, multiple grippers 320 converge circumferentially. The feeding hopper 400 is used to allow the soil inside the filling cylinder 310 to fall into the filling cylinder 310 after the filling cylinder 310 rotates to the filling station.

[0026] During filling operations, the rotating disk 200 rotates intermittently, stopping after each preset angle. The preset angle is the angle between two adjacent filling assemblies 300, ensuring that each filling assembly 300 rotates sequentially to the bagging station and the filling station. Figure 3 As shown, when there are 8 packing assemblies 300, the preset angle of rotation of the rotating disk 200 each time is 45°.

[0027] When the filling assembly 300 rotates with the rotating disk 200 to the bagging station, the rotating disk 200 stops rotating. During this time, the soil bag 900 is placed over the gripper 320. Then, the drive unit 330 corresponding to the filling assembly 300 is activated to drive the gripper 320 to move radially outward along the filling cylinder 310 from the first position to the second position. At this time, the gripper 320 tightens the opening of the soil bag 900. Under the action of friction, the relative position between the gripper 320 and the soil bag 900 is fixed.

[0028] Next, the rotating disk 200 continues to rotate at a preset angle, causing the filling assembly 300, which contains the soil-filled bag 900, to rotate from the bagging station to the filling station. At this time, the axis of the filling cylinder 310 of the filling assembly 300 is vertically upward, and the opening of the soil-filled bag 900 installed on it is upward. During the time when the rotating disk 200 stops rotating, soil is fed into the filling hopper. The soil fed into the filling hopper falls into the filling cylinder 310 under the action of gravity, and then falls into the soil-filled bag 900 through the filling cylinder 310.

[0029] When the weight of the soil bag 900 and the soil inside it increases to a level greater than the friction between the soil bag 900 and the gripper 320, the soil bag 900 gradually slides down until it detaches from the gripper 320. The detached soil bag 900 is then caught by a carrier and transferred to a designated storage location. After the gripper 320 detaches from the soil bag 900, the drive unit 330 corresponding to the filling assembly 300 is activated to drive the gripper 320 to radially inward reset to the first position. At this point, the filling assembly 300 has completed its reset, and the multiple grippers 320 converge circumferentially. This helps to prevent the soil in the filling cylinder 310 from continuing to fall when there is a large amount of soil inside. The soil is more likely to accumulate in the filling cylinder 310 due to the obstruction of the grippers 320, thus stopping its descent and preventing excessive soil from entering the soil bag 900, which would otherwise require manual leveling by workers.

[0030] Understandably, because the weight of the soil inside the soil bag 900 increases to be greater than the friction between the soil bag 900 and the gripper 320, the soil bag 900 can automatically detach from the gripper 320. Therefore, compared with the filling method of the existing auger feeder, the present invention can control the amount of filling material inside the soil bag 900. As a result, the consistency of the weight of the soil in each soil bag 900 after filling is better. There is no need for manual leveling or replenishing of the soil in the soil bag 900 afterward. Therefore, the present invention can improve the filling efficiency.

[0031] It should be added that, for example Figure 3As shown, the rotating disk 200 includes a disk body 201 and multiple bucket frames 202. The disk body 201 is rotatably connected to the frame 100, and the multiple bucket frames 202 are fixedly connected to the disk body 201 at equal intervals around the circumference. The multiple bucket frames 202 correspond one-to-one with and are fixedly connected to multiple packing cylinders 310.

[0032] It should also be added that, such as Figure 4 As shown, a servo motor 220 is mounted on the frame 100. The output shaft of the servo motor 220 is fixedly connected to a long shaft 210, which is coaxially fixedly connected to the disk body 201 of the rotating disk 200 to drive the rotating disk 200 to rotate intermittently. When it is necessary to adjust the time interval of the intermittent rotation of the servo motor 220, it can be modified through the control module of the servo motor 220.

[0033] It should also be added that, in order to achieve the goal of placing 900 soil bags on the outside of the gripper 320, the bags can be placed manually or automatically by using a robotic arm.

[0034] Furthermore, for the intermittent rotation of the rotating disk 200, either timed automatic control or jog control can be employed. Automatic control involves using a preset program in the servo motor 220 control module to control the servo motor 220 to rotate intermittently, thereby causing the rotating disk 200 to rotate intermittently. During a preset time period when the rotating disk 200 stops rotating, the soil-filled bag 900 is manually or mechanically placed onto the gripper 320. This automatic control is preferably used in conjunction with the automated method of robotic bagging. Jog control involves installing a jog switch on each filling cylinder 310. The electric switch is connected to the control module of the rotating disk 200. When a worker places the soil-filled bag 900 onto the gripper 320, they press the jog switch on that filling cylinder 310. Upon receiving the electrical signal, the control module controls the rotating disk 200 to rotate by a preset angle. This jog control is preferably used in conjunction with manual bagging.

[0035] It should also be noted that, in order to feed soil into the feeding hopper 400, this invention also requires the installation of an auger feeder, the soil outlet of which is located above the feeding hopper 400. The auger feeder also adopts an intermittent feeding method; specifically, when the rotating disc 200 rotates, the auger feeder does not rotate, and when the rotating disc 200 does not rotate, the auger feeder rotates.

[0036] In a further embodiment, such as Figure 5As shown, the driving component 330 includes a swing rod 331, a sliding ring 332, a cantilever 333, and an electromagnetic telescopic rod 334. The axis of the electromagnetic telescopic rod 334 is parallel to the axis of the packing cylinder 310. The housing of the electromagnetic telescopic rod 334 is fixed on the rotating disk 200. Specifically, the housing of the electromagnetic telescopic rod 334 is fixedly connected to the bucket frame 202. The cantilever 333 is fixedly connected to the telescopic end of the electromagnetic telescopic rod 334. The sliding ring 332 is fixedly connected to the cantilever 333 and is slidably sleeved on the outside of the packing cylinder 310. One end of the swing rod 331 is rotatably connected to the sliding ring 332, and the other end is rotatably connected to the gripper 320. The middle part of the gripper 320 is rotatably connected to the packing cylinder 310.

[0037] When the filling assembly 300 rotates to the bagging station and the soil bag 900 is fitted onto the outside of the gripper 320, the electromagnetic telescopic rod 334 is activated. The telescopic end of the electromagnetic telescopic rod 334 pulls the cantilever 333 to move away from the gripper 320. The cantilever 333 drives the sliding ring 332 to move away from the gripper 320 along the axis of the filling cylinder 310. Multiple grippers 320 move outward from the first position to the second position along the radial direction of the filling cylinder 310 around the hinge point in the middle. At this time, the positive pressure between the multiple grippers 320 and the soil bag 900 gradually increases. When the multiple grippers 320 move to the second position, the positive pressure between the grippers 320 and the soil bag 900 increases to a preset value to tension the soil bag 900.

[0038] It is understandable that the dynamic friction between the gripper 320 and the soil bag 900 is determined by the normal force between the gripper 320 and the soil bag 900, and the normal force between the gripper 320 and the soil bag 900 is determined by the swing angle of the gripper 320, which is determined by the stroke of the electromagnetic telescopic rod 334. Therefore, by adjusting the stroke of the electromagnetic telescopic rod 334, the dynamic friction between the gripper 320 and the soil bag 900 can be controlled, thereby adjusting the amount of soil to be filled in the soil bag 900.

[0039] It should be added that if a momentary control method is used, the electromagnetic telescopic rod 334 is connected to the momentary switch signal. After the worker puts the bag on, they press the momentary switch, which sends an electrical signal to the electromagnetic telescopic rod 334. The electromagnetic telescopic rod 334 starts, driving the gripper 320 to swing outward radially along the filling cylinder 310 to the second position, tightening the soil bag 900. When manually putting on the bag, it is important to push the soil bag 900 a little further towards one side of the gripper 320 to create a certain friction between the soil bag 900 and the gripper 320, preventing the soil bag 900 from falling off the gripper 320 during the rotation of the rotating disc 200. In addition, a photoelectric sensor needs to be installed at the filling station. The photoelectric sensor is connected to the electromagnetic telescopic rod 334 signal to detect whether the soil bag 900 has detached from the gripper 320 at the filling station. If the infrared signal emitted by the photoelectric sensor is blocked, it indicates that the soil bag 900 has not detached from the gripper 320, and the electromagnetic telescopic rod 334 remains stationary. If the infrared signal emitted by the photoelectric sensor is not blocked, it indicates that the soil bag 900 has detached from the gripper 320, and the electromagnetic telescopic rod 334 drives the gripper 320 to reset from the second position to the first position.

[0040] If an automatic control method is adopted, a first photoelectric sensor needs to be installed at the bagging station. The first photoelectric sensor is connected to the electromagnetic telescopic rod 334 and is used to detect whether there is a soil bag 900 at the bagging station. When the filling assembly 300 is in the bagging station, if the infrared signal emitted by the first photoelectric sensor is blocked, it means that a soil bag 900 has been placed on the gripper 320. The first photoelectric sensor sends an electrical signal to the electromagnetic telescopic rod 334, which drives the gripper 320 to swing radially outward from the first position to the second position along the filling cylinder 310, tightening the soil bag 900. If the infrared signal emitted by the first photoelectric sensor is not blocked, it means that no soil bag 900 has been placed on the gripper 320, and the electromagnetic telescopic rod 334 remains stationary. In addition, a second photoelectric sensor needs to be installed at the filling station. The second photoelectric sensor is connected to the electromagnetic telescopic rod 334 and is used to detect whether the soil bag 900 at the filling station has detached from the gripper 320. If the infrared signal emitted by the second photoelectric sensor is blocked, it indicates that the soil bag 900 has not detached from the gripper 320, and the electromagnetic telescopic rod 334 remains stationary. If the infrared signal emitted by the second photoelectric sensor is not blocked, it indicates that the soil bag 900 has detached from the gripper 320, and the electromagnetic telescopic rod drives the gripper 320 to reset from the second position to the first position.

[0041] In a further embodiment, such as Figure 5 and Figure 7As shown, the drive unit 330 also includes guide rods 335 and elastic elements 336. There are multiple guide rods 335, which are spaced apart and fixed on the rotating disk 200. Specifically, the guide rods 335 are fixedly connected to the bucket frame 202 at the corresponding position, and the guide rods 335 are slidably connected to the cantilever 333. The elastic elements 336 are sleeved on the outside of the guide rods 335, and the elastic elements 336 are configured to prevent the sliding ring 332 from moving towards the center of the rotating disk 200.

[0042] Multiple guide rods 335 are provided to guide and support the movement of the cantilever 333, so as to prevent the telescopic end of the electromagnetic telescopic rod 334 from bending and deforming.

[0043] The purpose of setting the elastic element 336 is to prevent the gripper 320 from exerting excessive pressure on the soil bag 900, which could cause the bag opening of the soil bag 900 to rupture. The reason is as follows: the existing electromagnetic telescopic rod 334 structurally includes a housing, a coil, an iron core (which is the same as the telescopic end of the previously mentioned electromagnetic telescopic rod 334), and a spring. The iron core is slidably connected to the housing and is fixedly connected to the cantilever 333. The spring is connected between the plunger and the housing, and the coil is located inside the housing and on the outer periphery of the iron core.

[0044] When the coil is energized, it generates a magnetic field of a certain intensity. The iron core moves towards the center of the coil under the action of the magnetic field, that is, the iron core moves away from the gripper 320. The intensity of the magnetic field is such that if the gripper 320 is not covered with a soil bag 900, the gripper 320 can move outward beyond the second position. However, since the gripper 320 is covered with a soil bag 900, the gripper 320 is restricted by the soil bag 900. Therefore, the gripper 320 can only move to the second position, and there is a preset positive pressure between the gripper 320 and the soil bag 900.

[0045] As the soil bag 900 gradually slides down, the contact area between the soil bag 900 and the clamp 320 gradually decreases. Since the magnetic field strength remains unchanged, the magnetic force remains unchanged. At this time, the pressure between the soil bag 900 and the clamp 320 increases, and the soil bag 900 will further expand and deform outward. That is, at this time, the iron core will continue to move away from the clamp 320. At this time, the elastic element 336 is compressed, which can prevent the iron core from continuing to move upward, reducing the amount of upward movement of the iron core, thereby avoiding excessive pressure from the clamp 320 on the soil bag 900 and causing the bag opening of the soil bag 900 to rupture.

[0046] In a further embodiment, such as Figure 5 As shown, the packing assembly 300 also includes a flexible cylinder 340, which is coaxially fixed to the bottom of the packing cylinder 310. When the gripper 320 is in the first position, the gripper 320 presses the flexible cylinder 340 inward until the port of the flexible cylinder 340 is in a gathered state.

[0047] The flexible cylinder 340 serves two purposes. First, it reduces soil spillage and waste. Since the flexible cylinder 340 is located inside the soil bag 900 during filling of the filling cylinder 310, there are no gaps between the soil bag 900 and the filling cylinder 310. This prevents soil from spilling out before the soil bag 900 is full. Second, it facilitates soil recovery. After filling, when the gripper 320 returns to its first position, it presses the flexible cylinder 340 inward until its port is closed. At this point, the lower port of the flexible cylinder 340 is closed, preventing the soil in the filling cylinder 310 and the flexible cylinder 340 from falling further and allowing for recovery.

[0048] Correspondingly, such as Figure 2 As shown, a collection hopper 500 is provided at intervals directly above the feeding hopper 400, and the two ends of the collection hopper 500 are connected to collect the soil falling from the filling cylinder 310 and return the soil to the feeding hopper 400.

[0049] When the flexible cylinder 340, with its port in a converged state, rotates upward to above the collecting hopper 500, under the guidance of the periphery of the packing cylinder 310, the flexible cylinder 340 and the remaining soil in the packing cylinder 310 slide towards the location of the collecting hopper 500 until they fall into the collecting hopper 500. The soil that falls into the collecting hopper 500 continues to fall downward into the feeding hopper 400 to achieve soil recycling.

[0050] In addition, soil at the inlet of the auger feeder is prone to "bridging" due to accumulation, preventing continuous entry into the auger screw. This reduces the amount of soil fed into the hopper 400, potentially resulting in insufficient soil falling into the soil bag 900 to disengage it from the gripper 320. Recycling the soil replenishes the hopper 400, preventing this problem.

[0051] In a further embodiment, the flexible cylinder 340 is made of either polyethylene plastic or polypropylene plastic.

[0052] The purpose of using polyethylene or polypropylene plastic is that polyethylene or polypropylene plastic not only has a certain degree of flexibility but also a certain degree of resilience. Its flexibility allows the ends to close together, and its resilience allows the flexible cylinder 340 to elastically return to its original position when the gripper 320 does not compress it, thus ensuring smooth descent of the soil.

[0053] In a further embodiment, such as Figure 5 As shown, a spring-loaded ring 341 is provided on the inner circumferential surface of the flexible cylinder 340.

[0054] The spring ring 341 is set to thicken the inner wall of the flexible cylinder 340 in one place, so as to increase the spring speed of the flexible cylinder 340 and enable it to quickly spring back to its original position after being squeezed by the gripper 320.

[0055] In a further embodiment, such as Figure 5 As shown, a wear-resistant part 342 is provided on the outer peripheral surface of the flexible cylinder 340 at a position corresponding to the gripper 320.

[0056] The wear-resistant part 342 is provided to enhance the wear resistance of the outer peripheral surface of the flexible cylinder 340 and the position corresponding to the gripper 320, so as to prevent wear and cracking at this position.

[0057] In a further embodiment, such as Figure 2 As shown, an automatic soil filling and bagging device for producing seedlings of southern medicinal herbs also includes a pneumatic carrier 600 for supporting the soil bags 900 after they have detached from the grippers 320.

[0058] A pneumatic carrier 600 is provided to support the soil bag 900 after it has detached from the gripper 320. Specifically, the pneumatic carrier 600 can extend directly below the filling station and catch the soil bag 900 when it falls.

[0059] In a further embodiment, such as Figure 2 As shown, an automatic soil filling and bagging equipment for the production of southern medicinal herb seedlings also includes a track trolley 800, on which a material bucket 810 is placed for collecting and transporting soil bags 900 to a designated location.

[0060] In use, the pneumatic carrier 600 supports the falling soil bags 900 and delivers them into the material bucket 810. When the material bucket 810 is filled with soil bags 900 to its maximum capacity, the material bucket 810 is transported to the end of the rail trolley 800. Finally, the worker removes the material bucket 810 and places it in the designated storage location.

[0061] The specific working process of the automatic soil-filling and bagging equipment for the production of southern medicinal herb seedlings provided by the present invention will be described in conjunction with the above embodiments: During the filling operation, the servo motor 220 and the auger feeder are started. Driven by the servo motor 220, the rotating disk 200 rotates intermittently. When the filling assembly 300 rotates with the rotating disk 200 to the bagging station, the rotating disk 200 stops rotating. At this time, the soil bag 900 is placed on the outside of the gripper 320 corresponding to the filling assembly 300 at the bagging station. Then, the drive component 330 corresponding to the filling assembly 300 is started, which pulls the cantilever 333 to move through the electromagnetic telescopic rod 334. The cantilever 333 drives the sliding ring 332 to move. The movement of the sliding ring 332 causes the swing rod 331 to rotate, which in turn causes the gripper 320 to rotate around the hinge point in the middle, so that the lower end of the gripper 320 swings from the first position to the second position. At this time, the gripper 320 tightens the soil bag 900 circumferentially. Next, the rotary disc 200 continues to rotate at a preset angle, causing the filling assembly 300, originally at the bagging station, to rotate to the filling station. At this time, the auger feeder starts, feeding a certain volume of soil into the feeding hopper 400. The soil in the feeding hopper 400 falls under the action of gravity, first falling into the filling cylinder 310, then through the filling cylinder 310 into the flexible cylinder 340, and finally through the flexible cylinder 340 into the soil bag 900. When the weight of the soil bag 900 and the soil inside it increases to a level greater than the friction between the soil bag 900 and the gripper 320, the soil bag 900 gradually slides down until it disengages from the gripper 320. When the soil bag 900 is detected to have disengaged from the gripper 320, the electromagnetic telescopic rod 334 resets, causing the lower end of the gripper 320 to swing from the second position back to the first position. At this time, the lower end of the gripper 320 presses inward against the flexible cylinder 340, causing the port of the flexible cylinder 340 to be in a closed state. Therefore, the remaining soil in the flexible cylinder 340 and the filling cylinder 310 will not spill downwards. As the rotating disk 200 continues to rotate, when the rotating disk 200 rotates to a position where the filling assembly 300 is obliquely above the collecting hopper 500, the soil in the filling cylinder 310 and the flexible cylinder 340 corresponding to this filling assembly 300 slides down the cylinder wall of the filling cylinder 310 under the action of gravity into the collecting hopper 500. The soil falling into the collecting hopper 500 continues to fall downwards into the feeding hopper 400, replenishing the soil in the feeding hopper 400 and realizing the recycling of the remaining soil.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.

Claims

1. An automatic soil-filling and bagging device for producing seedlings of southern medicinal herbs, used for filling soil bags with soil material, characterized in that, include: frame; The rotating disk has a horizontal axis and is rotatably connected to the frame; There are multiple packing assemblies, which are circumferentially spaced on the rotating disk; The packing assembly includes a packing cylinder, grippers, a flexible cylinder, and a drive unit. The axis of the packing cylinder coincides with the diameter of the rotating disk, and the packing cylinder is fixed on the rotating disk. Both ends of the packing cylinder are open. There are multiple grippers, which are circumferentially spaced at equal intervals on the outer periphery of the packing cylinder. The drive unit is used to drive the multiple grippers to move simultaneously along the radial direction of the packing cylinder. The packing assembly has a bagging station and a packing station in the circumferential direction; When the filling assembly rotates to the bagging station and the soil bag is placed outside the gripper, the drive unit moves the gripper radially outward from the first position to the second position to tension the soil bag. When the packing assembly rotates to the packing position and the soil bag disengages from the gripper, the drive unit causes the gripper to return to the first position radially inward, at which point multiple grippers circumferentially converge. The feeding hopper is used to allow the soil inside the packing cylinder to fall into the packing cylinder after the packing cylinder rotates to the packing position; The driving components include a rocker arm, a sliding ring, a cantilever, an electromagnetic telescopic rod, guide rods, and an elastic element. The axis of the electromagnetic telescopic rod is parallel to the axis of the packing cylinder. The housing of the electromagnetic telescopic rod is fixed on the rotating disk. The cantilever is fixedly connected to the telescopic end of the electromagnetic telescopic rod. The sliding ring is fixedly connected to the cantilever and is slidably fitted onto the outside of the packing cylinder. One end of the rocker arm is rotatably connected to the sliding ring, and the other end is rotatably connected to the gripper. The middle part of the gripper is rotatably connected to the packing cylinder. There are multiple guide rods, which are spaced apart and fixed on the rotating disk. The guide rods are slidably connected to the cantilever. The elastic element is fitted onto the outside of the guide rod and is configured to prevent the sliding ring from moving toward the center of the rotating disk. The flexible cylinder is coaxially fixed to the bottom of the packing cylinder. When the gripper is in the first position, the gripper squeezes the flexible cylinder inward until the port of the flexible cylinder is in a converged state. The electromagnetic telescopic rod includes a housing, a coil, an iron core, and a spring. The iron core is slidably connected to the housing and fixedly connected to the cantilever. When the soil bag gradually slides down, reducing the contact area between the soil bag and the gripper, the elastic element is compressed to prevent the iron core from continuing to move upward, thus avoiding excessive pressure from the gripper on the soil bag. By adjusting the stroke of the electromagnetic telescopic rod, the dynamic friction between the gripper and the soil bag can be controlled, thereby adjusting the amount of soil to be filled in the soil bag. When the weight of the soil bag and the soil inside it increases to a level greater than the friction between the soil bag and the gripper, the soil bag gradually slides down until it disengages from the gripper.
