Description

Technical Field

[0001] The present invention relates to the field of cultivation equipment, in particular to a green plant cultivation equipment for windbreak and sand fixation in sandy land. Background Art

[0002] In the prior art, the seedling transplanters for sandy land are divided into semi-automatic and fully automatic. The semi-automatic seedling transplanters need to be manually seated on the vehicle when working, and the seedlings are continuously placed in the planter, and then the planter inserts the seedlings into the sand. When the fully automatic seedling transplanter is working, the robotic arm moves horizontally by one station after taking the seedlings once (that is, moves to the next seedling taking position), takes the seedlings again and puts them into the planter. When a row of seedlings are taken, the seedling delivery component moves tiltedly and longitudinally by one station, driving the rack filled with seedlings to move down to the robotic arm seedling taking position, and then continues to repeat the above seedling taking process. At the same time, a sand fixing mechanism is also provided on the seedling transplanter. Specifically, a disc is provided on both sides of the planting sand. When the disc passes by, the straw mat spread on the surface of the sand will be inserted into the sand to form a sand barrier, so as to play a role in fixing the sand and ensure the growth environment of the seedlings. However, the current fully automatic seedling transplanters still have certain problems:

[0003] At the operation site of the fully automatic seedling transplanter in the sand, the problem of seedling leakage by the robotic arm will become more and more prominent as the operation time and area increase. When the seedling transplanter is started, the robotic arm will pick up seedlings according to the path set by the program. Once the clamping claws come into contact with seedlings with small size and weak stems, the clamping force cannot be adaptively adjusted, and the clamping may fail. After the clamping fails, the robotic arm will still move to the planter according to the established process to perform the "seedling release" action, causing idling. As the seedling transplanter continues to move, the seedling leakage phenomenon will continue to accumulate, forming staggered seedling-free areas on the sand. These blank spots not only weaken the continuity of the vegetation's wind and sand fixation, but the leaked seedlings piled up on the seedling delivery rack will also hinder the subsequent seedling retrieval process, and the staff need to stop the machine to deal with it. Summary of the Invention

[0004] The present invention is proposed in view of the problem that when the clamping claws in the above or existing technologies come into contact with small seedlings with thin stems, their clamping force cannot be adaptively adjusted, which may cause clamping failure and thus seedling leakage.

[0015] As a preferred solution of the present invention for the green plant cultivation equipment for windbreak and sand fixation in sandy land, the seedling planting mechanism includes an eccentric rod 1 and an eccentric rod 2 rotatably mounted on the frame, the ends of the eccentric rod 1 and the eccentric rod 2 are hinged with a connecting rod 1 and a connecting rod 2 respectively, a seedling planter is fixedly mounted at the end of the connecting rod 1, and the connecting rod 1 and the connecting rod 2 are hinged.

[0016] As a preferred solution of the present invention for the sandy land windbreak and sand fixation green plant cultivation equipment, the extrusion assembly includes a rod sleeve fixedly mounted on a frame and a slide rod slidably mounted in the rod sleeve, a pressure plate is fixedly mounted on the near-ground end of the slide rod, two return springs are fixedly mounted between the pressure plate and the rod sleeve, the two sets of return springs are arranged on the outside of the slide rod, a connecting plate is fixedly mounted on the far-ground end of the slide rod, a connecting sleeve is fixedly mounted on the frame, and a connecting rod that slides through the connecting sleeve is fixedly mounted on the near-ground side of the connecting plate.

[0018] Beneficial effects of the green plant cultivation equipment for windbreak and sand fixation in sandy land of the present invention:

[0019] 1. In this application, by setting up a seedling loading mechanism, the seedlings in the seedling rack are accurately separated one by one and pushed to the alignment component. The stepper motor indexing control of the notched turntable and the alignment turntable ensures that the seedlings are directed into the seedling planter, avoiding planting gaps caused by idling after the gripper misses the seedlings, making the seedling planting process fully automated and continuous. At the same time, it completely eliminates the uncertainty of the flexible grasping of the robotic arm, fundamentally solving the problem of missing seedlings caused by differences in seedling size, and significantly improving the efficiency and integrity of sand greening.

[0020] 2. In the present application, a sand-fixing mechanism is provided to adopt an intermittent insertion and pressure mechanism linked to the seedling planting action. When the seedling planter is pressed down, the mechanical linkage drives the pressure plate to insert the straw mat. When the seedling planter is lifted up, the pressure plate automatically resets, forming a dynamic insertion and pressure synchronized with the planting, accurately matching the seedling planting rhythm, and inserting and pressing the straw mat around the seedling only during planting. This not only reduces the damage to the straw mat caused by unnecessary pressure and ineffective energy consumption, but also ensures that the straw mat is tightly combined with the sand at the seedling planting site to form an effective sand-fixing barrier.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] Reference Figure 1 and Figure 2 The present embodiment provides a green plant cultivation equipment for windbreak and sand fixation in sandy land, which can realize the stepper motor indexing control of the notched turntable and the alignment turntable, ensure the directional introduction of the seedlings into the seedling planter, and avoid the effect of planting gaps caused by idling after the clamps miss the seeds. It includes a frame 1 and a carrying platform 2 arranged on the frame 1 and parallel to the ground, and used to carry the seedling rack 6. A seedling planting mechanism 4 for planting seedlings in the sand is arranged between the carrying platform 2 and the ground.

[0033] The frame 1 is provided with wheels for driving the frame 1 to move. The wheels are driven by an external motor in a sprocket transmission manner, and the seedling planting mechanism 4 is also driven by a sprocket transmission. The above-mentioned driving method is a prior art and therefore will not be elaborated in detail in this application.

[0034] Reference Figure 2 and Figure 3 , also includes a seedling loading mechanism 3, including a seedling delivery component 31, a seedling pushing component 32 and an alignment component 33. The seedling delivery component 31 is used to deliver a single seedling to the seedling pushing component 32 through the seedling rack 6. The seedling delivered to the seedling pushing component 32 is pushed toward the alignment component 33 under the push of the seedling pushing component 32, and is directed and aligned under the action of the alignment component 33 to be introduced into the seedling planting mechanism 4.

[0035] It should be noted that, in this embodiment, Artemisia ordosica is used as the planting object. The diameter of the stem of Artemisia ordosica seedlings is about 2-3 mm, the longitudinal distribution depth of the root system is ≤15 cm, and the lateral expansion range is ≤5 cm. The minimum growth space required for a single seedling is only a cylindrical area with a diameter of 10 cm. This biological characteristic is synergistically adapted to the design of the seedling planting mechanism 4, the seedling loading mechanism 3 and the sand fixation mechanism 5 in this embodiment, which not only meets the sand fixation needs during the group growth period of Artemisia ordosica seedlings, but also reserves growth space for adult plants. At the same time, the diameter, height and spacing between adjacent seedling racks 6 can be designed according to the longitudinal depth and lateral diameter of the root system of the Artemisia ordosica seedlings with soil.

[0036] Reference Figure 2 、 Figure 3 、 Figure 7 and Figure 8 The seedling planting mechanism 4 and the seedling loading mechanism 3 are both provided with two symmetrical groups. The seedling delivery component 31 includes a baffle 1 311, a baffle 2 312 and a baffle 3 313 fixedly mounted on the carrying platform 2. A accommodating area is formed between the baffle 1 311, the baffle 2 312 and the baffle 3 313, and the accommodating area is connected to the seedling pushing component 32.

[0037] It should be noted that the seedlings in the seedling rack 6 are arranged in a matrix, the communication port between the accommodating area and the seedling pushing assembly 32 only allows a single row of seedling racks 6 to enter, and the seedling pushing assembly 32 can only accommodate a single seedling rack 6.

[0038] Reference Figure 2 、 Figure 3 、 Figure 7 and Figure 8 The carrying platform 2 is provided with a cylinder 1 314 parallel to the baffle 2 312 and a cylinder 2 316 perpendicular to the baffle 2 312, and the output ends of the cylinder 1 314 and the cylinder 2 316 are fixedly installed with a seedling sending plate 1 315 and a seedling sending plate 2 317 respectively.

[0039] Reference Figure 2 、 Figure 3 、 Figure 7 and Figure 8 A guide groove perpendicular to the seedling feeding plate 1 315 and slidingly connected to the seedling feeding plate 1 315 is provided on the baffle 2 312, the cylinder 1 314 is fixedly mounted on the carrying platform 2, and the output end is fixedly connected to the seedling feeding plate 1 315, the seedling feeding assembly 31 also includes a mounting sleeve 34 fixedly mounted on the baffle 1 311, and the cylinder 2 316 is fixedly connected to the mounting sleeve 34.

[0040] Reference Figure 2 、 Figure 3 、 Figure 7 and Figure 8The seedling pushing assembly 32 includes an L-shaped plate 321 fixedly mounted on the side of the baffle 2 312 away from the baffle 1 311, and a push plate 323 is fixedly mounted on the side of the L-shaped plate 321 away from the seedling sending plate 1 315 through a return spring 1 322, and a limiting rod 324 is fixedly mounted on the side of the push plate 323 close to the seedling sending plate 1 315 that slides through the L-shaped plate 321.

[0041] It should be noted that the push plate 323 is provided with an inclined surface that matches the seedling rack 6.

[0042] During specific use, before work, the staff or the mechanical arm neatly arrange the seedling racks 6 to fill the entire accommodation area, and at the same time place the seedlings to be planted in the seedling racks 6.

[0043] When working, the output end of the cylinder 1 314 contracts first, driving the seedling feeding plate 1 315 to push all the seedling racks 6 as a whole to move closer to the side of the baffle 313, so that the row of seedling racks 6 closest to the baffle 313 is close to the baffle 313 and aligned with the seedling feeding plate 2 317. Then, the output end of the cylinder 2 316 pushes the seedling feeding plate 2 317, so that the seedling feeding plate 2 317 pushes this row of seedling racks 6 as a whole to move closer to the L-shaped plate 321. During the movement, the seedling rack 6 closest to the L-shaped plate 321 will squeeze and push The inclined surface of plate 323 drives the push plate 323 to move away from the alignment component 33 and compress the return spring 1 322 (in this process, the seedling rack 6 is close to the baffle 313, so the push plate 323 will be squeezed) until the seedling rack 6 closest to the L-shaped plate 321 moves to be close to the L-shaped plate 321. At this time, the seedling rack 6 is disengaged from the baffle 313, and the return spring 1 322 is reset and drives the push plate 323 to suddenly push the seedling rack 6 to slide toward the side of the alignment component 33, and the seedlings are accurately delivered into the alignment component 33.

[0044] Reference Figure 3 、 Figure 4 、 Figure 7 and Figure 8 The alignment component 33 includes a notched turntable 331 rotatably mounted on the side of the supporting platform 2 away from the seedling planting mechanism 4, and a plurality of notches are opened on the notched turntable 331. A notched ring 332 is fixedly mounted on the side of the supporting platform 2 away from the seedling planting mechanism 4 and is sleeved on the outside of the notched turntable 331. The notched ring 332, the L-shaped plate 321 and the accommodating area are interconnected.

[0045] It should be noted that the notched ring 332 on the outer periphery of the notched turntable 331 is aligned with the L-shaped plate 321. Each time the seedling pushing component 32 pushes the seedlings, the notched turntable 331 rotates one degree to allow the seedling rack 6 to fall into the notch. The number of notches is consistent with the number of seedling receiving tubes 335, ensuring that the seedlings are directed into the seedling planting mechanism 4.

[0046] Reference Figure 3 、 Figure 4 、 Figure 7 and Figure 8 The alignment component 33 also includes an alignment turntable 334 rotatably mounted on the frame 1 and located between the carrying platform 2 and the seedling planting mechanism 4. A number of seedling receiving tubes 335 distributed in a circumference and corresponding to the number of notches on the notched turntable 331 are vertically fixed on the alignment turntable 334. A seedling dropping bucket 336 located below the seedling receiving tube 335 and a retaining ring 333 slidingly passing through the seedling dropping bucket 336 are fixedly mounted on the frame 1. A collecting box 7 is fixedly mounted on the near-ground side of the carrying platform 2, and the carrying platform 2 is communicated with the collecting box 7.

[0047] It should be noted that the notched turntable 331 and the alignment turntable 334 are both driven by a stepper motor (not shown in the figure), and the retaining ring 333 is opened at the junction with the seedling drop bucket 336. After the seedling rack 6 passes through the alignment component 33 and sends the seedlings into the seedling receiving tube 335, the notched turntable 331 continues to rotate and drives the seedling rack 6 to move to the connection port between the supporting platform 2 and the collection box 7. The empty seedling rack 6 falls into the collection box 7 along the connection port for collection.

[0048] The inner diameter of the seedling receiving tube 335 is larger than the diameter of the seedling stem, ensuring that the seedling will not get stuck when it falls vertically into the seedling receiving tube 335, and the outer diameter of the seedling rack 6 is larger than the inner diameter of the connection between the supporting platform 2 and the seedling receiving tube 335, ensuring that the seedling can fall into the seedling receiving tube 335 while the seedling rack 6 will not fall.

[0049] During specific use, when the push plate 323 suddenly pushes the seedling rack 6 toward the alignment component 33 under the action of the return spring, the seedling rack 6 slides into the notched ring 332 on the outer periphery of the notched turntable 331 along the guide of the L-shaped plate (if the notched ring 332 has not yet rotated to align with the seedling rack 6, then the seedling rack 6 will contact the outer edge of the notched turntable 331 at this time, and the return spring 322 will still be under pressure and cannot be reset). At this time, the notched turntable 331 is driven by the stepping motor to rotate one division, so that the seedling rack 6 falls accurately into the notch of the notched turntable 331, and the inner diameter of the notched ring 332 is adapted to the outer diameter of the seedling rack 6.

[0050] When the notched turntable 331 rotates, the alignment turntable 334 is driven by the same stepping motor through the transmission mechanism and rotates synchronously to the corresponding angle. When the seedling rack 6 rotates with the notched turntable 331 to just above the seedling receiving tube 335, the seedlings in the seedling rack 6 fall into the seedling receiving tube 335 under the action of gravity and are blocked by the retaining ring 333. Then, the stepping motor continues to drive the notched turntable 331 and the alignment turntable 334 to rotate one division to perform the next seedling feeding, pushing and alignment operations. When the seedling receiving tube 335 continues to rotate with the alignment turntable 334 and reaches just above the seedling dropping bucket 336, the seedlings in the seedling receiving tube 335 move to the opening of the retaining ring 333, and are thereby transferred into the seedling dropping bucket 336 under the action of gravity, and enter the seedling planting mechanism 4 under the guidance of the seedling dropping bucket 336.

[0051] When the seedlings fall from the seedling rack 6 into the seedling receiving tube 335, the empty seedling rack 6 continues to rotate with the notched turntable 331. When it reaches the connection port between the carrying platform 2 and the collection box 7, the empty seedling rack 6 slides into the collection box 7 along the connection port under the action of gravity for collection.

[0052] It should be noted that an elastic baffle is provided at the entrance of the collection box 7 to prevent the empty seedling racks 6 from rebounding when they fall. At the same time, the vibration plate at the bottom of the collection box 7 is activated once every period of time to disperse the accumulated empty seedling racks 6 to avoid blockage. The volume of the collection box 7 is designed to accommodate the empty seedling racks 6 generated by a single operation. The above-mentioned elastic baffle and its vibration operation principle are all existing technologies, and therefore, they will not be elaborated in detail in this application.

[0053] Reference Figure 2 and Figure 5 The seedling planting mechanism 4 includes an eccentric rod 1 41 and an eccentric rod 2 42 rotatably mounted on the frame 1. The ends of the eccentric rod 1 41 and the eccentric rod 2 42 are hinged with a connecting rod 1 43 and a connecting rod 2 44 respectively. A seedling planting device 45 is fixedly mounted at the end of the connecting rod 1 43, and the connecting rod 1 43 and the connecting rod 2 44 are hinged.

[0054] It should be noted that the eccentric rod 1 41 and the eccentric rod 2 42 rotate synchronously through sprocket transmission (known technology). When the eccentric rod 1 41 and the eccentric rod 2 42 rotate, the seedling planter 45 moves along the elliptical trajectory of "pressing down - entering the soil - lifting up".

[0055] It should be noted that, during the movement of the frame 1, the eccentric rod 1 41 and the eccentric rod 2 42 are driven to rotate synchronously. During the rotation process, when the eccentric rod 1 41 rotates to the lowest point, the connecting rod 1 43 and the connecting rod 2 44 push the seedling planter 45 vertically downward to insert the sand. As the eccentric rod 1 41 and the eccentric rod 2 42 continue to rotate, the seedling planter 45 is gradually lifted up to complete a planting action.

[0056] Reference Figure 2 and Figure 5 The frame 1 is provided with a sand-fixing mechanism 5 for inserting straw mats laid on the sand surface into the sand to form a sand barrier. The sand-fixing mechanism 5 includes an insertion and pressing component 51 and an extrusion component 52 for intermittently driving the insertion and pressing component 51 as the seedling planting mechanism 4 performs a seedling planting action.

[0057] Reference Figure 2 、 Figure 5 and Figure 6The extrusion assembly 52 includes a rod sleeve 511 fixedly mounted on the frame 1 and a sliding rod 514 slidably mounted in the rod sleeve 511 and perpendicular to the ground. A pressure plate 513 is fixedly mounted on the near-ground end of the sliding rod 514, and a second return spring 512 is fixedly mounted between the pressure plate 513 and the rod sleeve 511. The second return spring 512 is sleeved on the outside of the sliding rod 514. A connecting plate 515 is fixedly mounted on the far-ground end of the sliding rod 514. A connecting sleeve 517 is fixedly mounted on the frame 1, and a connecting rod 516 that slides through the connecting sleeve 517 is fixedly mounted on the near-ground side of the connecting plate 515.

[0058] Reference Figure 2 、 Figure 5 and Figure 6 The extrusion assembly 52 includes a compression rod 522 fixedly mounted on the connecting rod 516 and perpendicular to the connecting rod 516, and an extrusion rod 521 intermittently matched with the compression rod 522 is fixedly mounted on the side of the connecting rod 43 close to the compression rod 522.

[0059] When the eccentric rod 521 is in contact with the upper end face of the compression rod 522, the swing angle of the connection rod 43 gradually increases, and the extrusion rod 521 applies a downward thrust to the compression rod 522, and the thrust is transmitted to the connecting plate 515 connected thereto through the connecting rod 516, thereby driving the sliding rod 514 to move vertically downward in the rod sleeve 511. When the eccentric rod 41 is rotated and lifted, the return spring 512 is gradually reset, driving the slide bar 514 to slide upward along the rod sleeve 511, and the slide bar 514 drives the connecting plate 515 and the connecting rod 516 to move upward synchronously, so that the pressure plate 513 gradually leaves the surface of the straw mat and returns to its initial position. In this way, as the downward and upward movement of the seedling planter 45 cycles, the extrusion rod 521 and the pressure rod 522 intermittently contact, driving the pressure plate 513 to achieve intermittent straw mat insertion and pressure synchronization with the seedling planting action, ensuring that the straw mat is accurately inserted and fixed around the seedling each time the seedling is planted, forming a sand barrier structure that prevents wind and sand.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
