Description

Technical Field

[0001] The invention belongs to the field of submerged plant planting, and in particular relates to a submerged plant planting and transplanting device and method. Background Art

[0002] Submerged plants refer to large aquatic plants whose entire plant body is located below the water layer and survives by fixing. Their roots are sometimes underdeveloped or degenerate. All parts of the plant body can absorb water and nutrient-rich substances, and can photosynthesize and release oxygen at the bottom of the water. Since submerged plants have a unique way of survival, ecological projects often use submerged plants to purify water and improve the quality of surface water. The planting of submerged plants is restricted by conditions such as water sources, water area, navigation, and cost. Some water ecological restoration projects require water construction and planting.

[0003] Planting submerged plants with water has high requirements for water quality, bottom improvement, water transparency, and fish control. In traditional construction, the planting methods of weighted seeding and mud seeding waste seedlings, uneven planting density, large missed planting area, slow plant growth after planting, and a long time for the project to see results. To this end, the patent with application number 202221771253.5 proposes a submerged plant planting device, which uses a rod with a slot at the end, the slot is 1.5-2cm wide and 3-4cm deep, and the planting depth is increased by the length of the rod. However, this technology requires manual operation throughout the process, with low efficiency and uneven planting density. In addition, before planting, the plants need to be soaked in the roots and other operations. The traditional method uses offshore operations and cannot be operated continuously. Summary of the invention

[0004] The object of the present invention is to provide a submerged plant planting device and method, which can realize continuous operation from preparing soaking agent to automatic pole planting, with high efficiency and uniform planting density.

[0005] The technical solution adopted by the present invention is:

[0006] A submerged plant planting and transplanting device comprises a base, a seedling outlet is arranged below one end of the base; a planting mechanism, a seedling storage mechanism and a conveying mechanism are arranged on the base;

[0007] The planting mechanism includes a planting bracket fixed on a base, the planting bracket is located just above the seedling outlet, a No. 1 motor is fixed on the planting bracket, and a plurality of planting rod platforms are provided, a planting rod is slidably provided on each planting rod platform, a No. 1 rack is fixed on the planting rod, a No. 1 transmission shaft is fixedly connected to the No. 1 motor shaft, a No. 1 gear corresponding to the number of the planting rods is provided on the No. 1 transmission shaft, and the No. 1 gear is meshingly connected with the No. 1 rack.

[0008] During operation, the seedlings are first placed in the seedling storage mechanism, and then transmitted to the bottom of the planting mechanism through the conveying mechanism; the No. 1 motor drives the No. 1 transmission shaft to rotate, and then drives the insertion rod to slide downward along the insertion rod platform through the No. 1 gear and the No. 1 rack to insert the seedlings into the soil, and the No. 1 motor reverses to pull out the insertion rod.

[0009] Furthermore, the rod insertion platform is slidably connected with the seed insertion bracket, and a sliding rod is fixed on the side of the rod insertion platform; an electric cylinder is fixed on the base, and a push plate is fixed on the telescopic rod of the electric cylinder, and a number of slide grooves corresponding to the slide rod are provided on the push plate, wherein the middle slide groove is in the vertical direction, and the slide grooves on both sides are inclined upward;

[0010] A key strip is axially arranged on the No. 1 transmission shaft, and correspondingly, a key groove is arranged on the axis of the No. 1 gear, and the No. 1 transmission shaft is slidably connected to the No. 1 gear along the axial direction; a No. 1 baffle is fixed on the rod insertion platform, and the No. 1 baffle is slidably connected to the No. 1 transmission shaft at the same time.

[0011] This setting is used to adjust the distance between the insertion rods, and then adjust the planting density. Taking the three insertion rods of this embodiment as an example, when the telescopic rod of the electric cylinder is extended, the middle slide rod is not affected, while the slide rods on both sides are affected by the inclined slide groove and will move closer to the middle, driving the insertion rod platforms on both sides to move toward the middle on the planting bracket, thereby reducing the distance between the insertion rods. When the telescopic rod of the electric cylinder is retracted, the distance is increased. The purpose of setting the No. 1 baffle is that when the insertion rod platform drives the insertion rod to move, the No. 1 baffle is used to push the No. 1 gear to move along the No. 1 transmission shaft, keeping the No. 1 gear and the No. 1 rack always engaged.

[0012] Furthermore, the seedling storage mechanism includes a storage box without a cover, support plates are arranged on both sides of the storage box, and multiple trays are placed on the support plates. The trays include a horizontal plate overlapped on the support plate, and a plurality of circular holes are opened on the horizontal plate. A vertical plate is also fixed on the horizontal plate, and a double sliding rod is slidably provided in the vertical plate. A spring is sleeved on the double sliding rod. A sliding plate is fixed at one end of the double sliding rod, and a cava is fixed at the other end. The sliding plate is slidably connected to the horizontal plate, and the cava is located in the circular hole; a loading and unloading rod is also fixed on the horizontal plate.

[0013] Before operation, the seedlings are placed in the round hole and fixed with slips. When placing, pull the sliding plate so that the arc surface of the slips is close to one side of the round hole and compresses the spring. After placing, release the sliding plate. Under the action of the spring, the slips and one side of the round hole clamp the seedlings. During operation, the entire tray is lifted by the loading and unloading rod and transported to the planting mechanism by the conveying mechanism for planting.

[0014] Furthermore, L-shaped slide rails are respectively provided on both sides of the storage box, a No. 2 rack and an L-shaped support plate are fixed on one side of the storage box, a No. 2 motor is fixed on the L-shaped support plate, a No. 1 rectangular frame is fixed on the rotating shaft of the No. 2 motor, a stirring wheel shaft is horizontally provided in the two L-shaped slide rails, one end of the stirring wheel shaft is simultaneously inserted into the No. 1 rectangular frame, and a No. 3 gear is fixed at the end, and the No. 3 gear is meshed and connected with the No. 2 rack.

[0015] In order to better ensure the survival rate of seedlings, the roots need to be soaked in the agent before planting. For this reason, when the tray is not placed in the storage box, the soaking agent is prepared first. During the preparation, it is necessary to stir and mix continuously. In order to enable the storage box to be used for both storage and preparation, if it is set as a conventional stirring shaft, it will affect the storage of the tray. Therefore, this stirring method is adopted. The No. 2 motor drives the No. 1 rectangular frame to rotate clockwise, and the stirring wheel shaft is lowered from the vertical section of the L-shaped slide rail to the horizontal section. Then the No. 3 gear meshes with the No. 2 rack and starts to rotate. At the same time, it is driven by the No. 1 rectangular frame to move horizontally, and then the agent is evenly stirred. After preparation, the stirring wheel shaft returns to its original position. When the L-shaped slide rail has a certain height, it will not affect the storage and retrieval of the tray.

[0016] Furthermore, the conveying mechanism includes a No. 3 motor fixed on the base, a swing arm is fixedly connected to the rotating shaft of the No. 3 motor, and a No. 2 rectangular frame is slidably arranged on the base, a sliding seat is arranged in the No. 2 rectangular frame, and the sliding seat is rotatably connected to the swing arm; a No. 4 motor is fixed on the sliding seat, and a lifting rod and a No. 3 rack are slidably arranged, and one end of the lifting rod and the No. 3 rack is fixedly connected; a No. 4 gear is fixed on the rotating shaft of the No. 4 motor, and the No. 4 gear is meshingly connected with the No. 3 rack; the lifting rod matches the size of the loading and unloading rod.

[0017] When the seedlings are soaked in the agent, motor No. 3 aligns the lifting rod with the loading and unloading rod through the swing arm. When the swing arm continues to turn right, the slide seat will move down in the No. 2 rectangular frame, so that the lifting rod is also aligned with the loading and unloading rod in the horizontal direction; then, motor No. 4 drives rack No. 3 to move through gear No. 4, driving the lifting rod to insert into the loading and unloading rod; then, motor No. 3 reverses and lifts the tray upward through the swing arm, slide seat, lifting rod and loading and unloading rod (this operation is performed from near to far, first lift the nearby tray and take out the seedlings, and then send the empty tray to somewhere else, so when lifting the distant tray, it will not be affected by the nearby tray), motor No. 3 continues to reverse, causing the swing arm to change from tilting to the right to tilting to the left. At this time, rectangular frame No. 2 also moves to the left, lowers the seedlings and returns, and continues to pick up the seedlings on other trays.

[0018] Furthermore, the conveying mechanism also includes a conveyor belt located between the planting mechanism and the storage box.

[0019] The taken out seedlings can be placed on a conveyor belt and automatically slide under the insertion rod to be planted in the soil.

[0020] Furthermore, a No. 4 rack is fixed on the insertion rod, and at the same time, a No. 2 transmission shaft is rotatably connected to the planting bracket, and a No. 5 gear meshing with the No. 4 rack is slidably provided on the No. 2 transmission shaft, and a No. 2 baffle is connected, and the No. 2 baffle is fixed on the insertion rod platform; the No. 2 baffle, the No. 5 gear, and the No. 2 transmission shaft have the same structure as the No. 1 baffle, the No. 1 gear, and the No. 1 transmission shaft, respectively, and are connected in the same way;

[0021] A No. 1 pulley is fixed at both ends of the No. 2 transmission shaft, a No. 2 pulley and a ratchet are fixed on the rotating shaft of the conveyor belt, and the No. 1 pulley is connected with the No. 2 pulley through a belt.

[0022] When the rod moves upward, it drives the No. 4 rack to move upward, and drives the conveyor belt to move a certain distance through the No. 5 gear, the No. 2 transmission shaft, the No. 1 pulley, the No. 2 pulley and the ratchet. After that, when the rod moves downward, the conveyor belt does not move due to the one-way working principle of the ratchet. Therefore, each time the seedlings are planted, the pre-planted seedlings are moved once.

[0023] Furthermore, two guide plates are fixed on the rod insertion platform. The guide plates are parallel to the moving direction of the conveyor belt and are located above the conveyor belt. A push rod is fixed on one of the guide plates.

[0024] If the seedlings are placed directly on the conveyor belt and allowed to move forward, they may deviate in other directions during the movement and fail to reach the exact position below the insertion rod. For this reason, a guide plate is provided. When the lifting rod takes out the tray and lowers it between the two guide plates, the push rod pushes the sliding plate, causing the slips to release the clamped seedlings, allowing the seedlings to be placed between the two guide plates. In this way, due to the action of the two guide plates, the seedlings will reach the exact position below the insertion rod.

[0025] A method for planting submerged plants comprises the following steps:

[0026] Step 1: Prepare plant soaking agent in the storage box;

[0027] Plant soaking agents are prepared according to water quality indicators and sediment test data. The main ingredients include microorganisms, disinfectants, plant root promoters and root protectors, growth agents and trace elements. They need to be proportioned according to the results of sediment test data and are used to improve water quality and sediment and promote plant rooting and growth.

[0028] Step 2: Place the seedlings to be planted into the tray, and then place the tray into the storage box and soak for 3-5 hours;

[0029] Step 3: After the soaking is completed, the conveying mechanism picks up the tray closest to the third motor and moves it between a set of guide plates. The push rod releases the sliding plate, allowing the seedlings to fall from the tray to the conveyor belt, and the corresponding number of seedlings are placed according to the needs. After that, the conveying mechanism returns the empty tray to the hull or the shore and re-places the seedlings.

[0030] Step 4: Before planting, adjust the distance between the planting rods according to the planting density, and then the No. 1 motor drives the planting rods to perform the planting operation.

[0031] Beneficial effects of the present invention:

[0032] By setting an inclined slide, cooperating with an electric cylinder and a sliding rod, the distance between the insertion rods can be easily adjusted, thereby adjusting the planting density; a sliding plate, a slip, and a horizontal plate with round holes are provided to achieve the clamping and unloading of the seedlings. At the same time, the semi-circular slip can also prevent damage to the seedlings to the greatest extent; the conveying mechanism composed of a motor, a swing arm, a rectangular frame, a rack, etc. can conveniently transfer the seedling tray; through the coordination of the rack, pulley, ratchet and conveyor belt, a perfect coordination is achieved between each planting and the discontinuous forward movement of a single seedling, effectively ensuring the uniformity of planting.

[0044] like Figures 1 to 10 As shown, a submerged plant planting and transplanting device includes a base 1, and a seedling outlet 101 is provided below one end of the base 1; a transplanting mechanism 2, a seedling storage mechanism 3 and a conveying mechanism 4 are provided on the base 1; the transplanting mechanism 2 includes a transplanting bracket 201 fixed on the base 1, the transplanting bracket 201 is located directly above the seedling outlet 101, a No. 1 motor 202 is fixed on the transplanting bracket 201, and a plurality of insertion rod platforms 203 are provided, an insertion rod 204 is slidably provided on each insertion rod platform 203, a No. 1 rack 205 is fixed on the insertion rod 204, a No. 1 transmission shaft 206 is fixedly connected to the rotating shaft of the No. 1 motor 202, and a No. 1 gear 207 corresponding in number to the insertion rod 204 is provided on the No. 1 transmission shaft 206, and the No. 1 gear 207 is meshed and connected with the No. 1 rack 205.

[0045] During operation, the seedlings are first placed in the seedling storage mechanism 3, and then the seedlings are conveyed to the bottom of the planting mechanism 2 through the conveying mechanism 4; the No. 1 motor 202 drives the No. 1 transmission shaft 206 to rotate, and then drives the insertion rod 204 to slide downward along the insertion rod platform 203 through the No. 1 gear 207 and the No. 1 rack 205 to insert the seedlings into the soil, and the No. 1 motor 202 reverses to pull out the insertion rod 204.

[0046] The rod insertion platform 203 is slidably connected to the planting bracket 201, and a sliding rod 208 is fixed on the side of the rod insertion platform 203; an electric cylinder 209 is fixed on the base 1, and a push plate 210 is fixed on the telescopic rod of the electric cylinder 209, and a number of sliding grooves 211 corresponding to the sliding rod 208 are provided on the push plate 210, wherein the middle sliding groove 211 is in a vertical direction, and the sliding grooves 211 on both sides are inclined upward; a key strip is axially provided on the No. 1 transmission shaft 206, and correspondingly, a key groove is provided on the axis of the No. 1 gear 207, and the No. 1 transmission shaft 206 is slidably connected to the No. 1 gear 207 along the axial direction; a No. 1 baffle plate 212 is fixed on the rod insertion platform 203, and the No. 1 baffle plate 212 is slidably connected to the No. 1 transmission shaft 206 at the same time.

[0047] This setting is used to adjust the distance between the insertion rods 204, and then adjust the planting density. Taking the three insertion rods 204 of this embodiment as an example, when the telescopic rod of the electric cylinder 209 is extended, the middle slide rod 208 is not affected, and the slide rods 208 on both sides are affected by the inclined slide groove 211, and will move closer to the middle, driving the insertion rod platform 203 on both sides to move toward the middle on the planting bracket 201, thereby reducing the distance between the insertion rods 204. When the telescopic rod of the electric cylinder 209 is retracted, the distance is increased. The purpose of setting the first baffle plate 212 is that when the insertion rod platform 203 drives the insertion rod 204 to move, the first baffle plate 212 is used to push the first gear 207 to move along the first transmission shaft 206, so as to keep the first gear 207 and the first rack 205 always meshed.

[0048] The seedling storage mechanism 3 includes a storage box 301 without a cover, support plates 302 are arranged on both sides of the storage box 301, and multiple trays 303 are placed on the support plates 302. The trays 303 include a horizontal plate 3031 overlapped on the support plate 302, and a plurality of circular holes 3032 are opened on the horizontal plate 3031. A vertical plate 3033 is also fixed on the horizontal plate 3031. A double sliding rod 3034 is slidably arranged in the vertical plate 3033, and a spring 3035 is sleeved on the double sliding rod 3034. A sliding plate 3036 is fixed at one end of the double sliding rod 3034, and a slip 3037 is fixed at the other end. The sliding plate 3036 is slidably connected to the horizontal plate 3031, and the slip 3037 is located in the circular hole 3032; a loading and unloading rod 3038 is also fixed on the horizontal plate 3031.

[0049] Before operation, the seedling is placed in the circular hole 3032 and fixed with the slip 3037. When placing, the sliding plate 3036 is pulled so that the arc surface of the slip 3037 is close to one side of the circular hole 3032 and the spring 3035 is compressed. After placing, the sliding plate 3036 is released, and under the action of the spring 3035, the slip 3037 and one side of the circular hole 3032 clamp the seedling. When operating, the entire tray 303 is lifted by the loading and unloading rod 3038 and transported to the planting mechanism 2 by the conveying mechanism 4 for planting.

[0050] L-shaped slide rails 304 are respectively provided on both sides of the storage box 301, and a No. 2 rack 305 and an L-shaped support plate 306 are fixed on one side of the storage box 301, a No. 2 motor 307 is fixed on the L-shaped support plate 306, and a No. 1 rectangular frame 308 is fixed on the rotating shaft of the No. 2 motor 307, and a No. 1 rectangular frame 308 is fixed on the rotating shaft of the No. 2 motor 307. A stirring wheel shaft 309 is horizontally provided in the two L-shaped slide rails 304, and one end of the stirring wheel shaft 309 is simultaneously inserted into the No. 1 rectangular frame 308, and a No. 3 gear 310 is fixed on the end, and the No. 3 gear 310 is meshed and connected with the No. 2 rack 305.

[0051] In order to better ensure the survival rate of seedlings, the roots need to be soaked in the medicine before planting. For this purpose, when the tray 303 is not placed in the storage box 301, the soaking medicine is prepared first. During the preparation, it is necessary to stir and mix continuously. In order to enable the storage box 301 to be used for both storage and preparation, if it is set as a conventional stirring shaft, it will affect the storage of the tray 303. Therefore, this stirring method is adopted. The No. 2 motor 307 drives the No. 1 rectangular frame 308 to rotate clockwise, and the stirring wheel shaft 309 is lowered from the vertical section of the L-shaped slide rail 304 to the horizontal section. Then the No. 3 gear 310 engages with the No. 2 rack 305 and starts to rotate. At the same time, it is driven by the No. 1 rectangular frame 308 to move horizontally, and then the medicine is evenly stirred. After preparation, the stirring wheel shaft 309 returns to its original position. When the L-shaped slide rail 304 has a certain height, it will not affect the storage and access of the tray 303.

[0052] The conveying mechanism 4 includes a No. 3 motor 401 fixed on the base 1, a swing arm 402 is fixedly connected to the rotating shaft of the No. 3 motor 401, and a No. 2 rectangular frame 403 is also slidably arranged on the base 1, a slide 404 is arranged in the No. 2 rectangular frame 403, and the slide 404 is rotatably connected to the swing arm 402; a No. 4 motor 405 is fixed on the slide 404, and a lifting rod 406 and a No. 3 rack 407 are slidably arranged, and one end of the lifting rod 406 and the No. 3 rack 407 are fixedly connected; a No. 4 gear 408 is fixed on the rotating shaft of the No. 4 motor 405, and the No. 4 gear 408 is meshed and connected with the No. 3 rack 407; the lifting rod 406 matches the size of the loading and unloading rod 3038.

[0053] When the seedlings are soaked in the medicine, the third motor 401 aligns the lifting rod 406 with the loading and unloading rod 3038 through the swing arm 402 (from Figure 2It can be seen that when the second rectangular frame 403 moves to the rightmost end, the lifting rod 406 is exactly aligned with the loading and unloading rod 3038 in the vertical direction. At this time, the second rectangular frame 403 cannot continue to move right). When the swing arm 402 continues to turn right, the slide 404 moves down in the second rectangular frame 403, so that the lifting rod 406 is also aligned with the loading and unloading rod 3038 in the horizontal direction; then, the fourth motor 405 drives the third rack 407 to move through the fourth gear 408, driving the lifting rod 406 to insert into the loading and unloading rod 3038; then, the third motor 401 Reverse, lift the tray 303 upwards through the swing arm 402, slide 404, lifting rod 406, and loading and unloading rod 3038 (this operation is performed from near to far, first lift the nearby tray 303 and take out the seedlings, and then send the empty tray 303 to somewhere else, so when lifting the distant tray 303, it will not be affected by the nearby tray 303), the No. 3 motor 401 continues to reverse, so that the swing arm 402 changes from tilting to the right to tilting to the left. At this time, the No. 2 rectangular frame 403 also moves to the left, puts the seedlings down and returns, and continues to pick up the seedlings on other trays.

[0054] The conveying mechanism 4 also includes a conveyor belt 409 between the planting mechanism 2 and the storage box 301. The taken seedlings can be placed on the conveyor belt 409 and automatically slide under the planting rod 204 to be planted in the soil.

[0055] A fourth rack 213 is fixed on the insertion rod 204. At the same time, a second transmission shaft 214 is rotatably connected to the planting bracket 201. A fifth gear 215 meshing with the fourth rack 213 is slidably provided on the second transmission shaft 214, and is connected to a second baffle 216, which is fixed on the insertion rod platform 203; the second baffle 216, the fifth gear 215, and the second transmission shaft 214 have the same structure as the first baffle 212, the first gear 207, and the first transmission shaft 206, respectively, and are connected in the same way; a first pulley 217 is fixed at both ends of the second transmission shaft 214, a second pulley 218 and a ratchet 219 are fixed on the rotating shaft of the conveyor belt 409, and the first pulley 217 is connected to the second pulley 218 through a belt 220.

[0056] When the rod 204 moves upward, it drives the fourth rack 213 to move upward, and drives the conveyor belt 409 to move a certain distance through the fifth gear 215, the second transmission shaft 214, the first pulley 217, the second pulley 218 and the ratchet 219. Afterwards, when the rod 204 moves downward, the conveyor belt 409 does not move due to the one-way working principle of the ratchet 219. Therefore, each time the seedlings are planted, the pre-planted seedlings are moved once.

[0057] Two guide plates 410 are fixed on the rod insertion platform 203 . The guide plates 410 are parallel to the moving direction of the conveyor belt 409 and are located above the conveyor belt 409 . A push rod 411 is fixed on one of the guide plates 410 .

[0058] If the seedlings are directly placed on the conveyor belt 409 and allowed to move forward, they may deviate in other directions during the movement, and thus fail to accurately reach the bottom of the insertion rod 204. For this purpose, a guide plate 410 is provided. When the lifting rod 406 takes out the tray 303 and lowers it between the two guide plates 410, the push rod 411 pushes the sliding plate 3036, so that the slips 3037 release the clamped seedlings, so that the seedlings are placed between the two guide plates 410. In this way, due to the action of the two guide plates 410, the seedlings will accurately reach the bottom of the insertion rod 204.

[0059] A method for planting submerged plants comprises the following steps:

[0060] Step 1: Prepare plant soaking agent in the storage box 301;

[0061] Plant soaking agents are prepared according to water quality indicators and sediment test data. The main ingredients include microorganisms, disinfectants, plant root promoters and root protectors, growth agents and trace elements. They need to be proportioned according to the results of sediment test data and are used to improve water quality and sediment and promote plant rooting and growth.

[0062] Step 2: Place the seedlings to be planted into the tray 303, and then place the tray 303 as a whole into the storage box 301 to soak for 3-5 hours;

[0063] Step 3: After the soaking is completed, the conveying mechanism 4 picks up a tray 303 closest to the third motor 401 and moves it between a set of guide plates 410 (three sets of guide plates 410 are provided in this embodiment), and releases the sliding plate 3036 through the push rod 411, so that the seedlings fall from the tray 303 onto the conveyor belt 409, and a corresponding number of seedlings are placed as needed; thereafter, the conveying mechanism 4 returns the empty tray 303 to the hull or the shore, and re-places the seedlings;
