Description

Technical Field

[0001] The invention relates to the technical field of Suaeda salsa planting, and in particular to a Suaeda salsa planting device and method for repairing saline-alkali land. Background Art

[0002] Suaeda salsa is a plant adapted to saline-alkali environments and can be planted in coastal saline soil areas or saline-alkali land. In order to repair saline-alkali land, some areas adopt the method of planting Suaeda salsa. Due to the fragile soil environment of saline-alkali land, no-till seeders are usually used for furrow sowing during the sowing process. The current no-till seeders, thanks to their special furrow opener design, can accurately place seeds to the predetermined depth without destroying existing vegetation, reducing the number of contacts with the soil. However, a hardened salt crust often forms on the surface of saline-alkali land, and some areas still have a large amount of undecomposed plant residues, which can easily affect the effect of the furrow opener and affect the seeds from falling to the predetermined depth. This situation is more likely to occur in moderate and above saline-alkali land.

[0003] For example, a no-tillage planting device disclosed in Publication No. CN103650708B uses a corrugated disc knife for furrowing, which has good passability. However, when it comes to hardened salt crust on saline-alkali land, it not only causes large wear and tear but also causes large damage to the soil structure, which is not conducive to seed germination. The planting device for improving saline-alkali land disclosed in Publication No. CN220712025U can sow and irrigate seeds, but after sowing the seeds in the planting pit, it does not effectively cover the seeds, making them easily affected by wind erosion, bird damage and other external factors, which affect seed germination. In addition, the planting pit needs to be dug in advance before use, which requires a long operation cycle.

[0004] Therefore, a device and method for planting Suaeda salsa for repairing saline-alkali land are proposed. Summary of the Invention

[0057] The present invention provides a device and method for planting Suaeda salsa for repairing saline-alkali land. Compared with the existing technology, it has the following advantages:

[0058] (1) The device and method for planting saltwort for repairing saline-alkali land are provided with a shell, a fixed contact, a follower contact, a power motor, an output shaft, a gear 1, a gear 2, a steel belt transmission unit, a drive motor, a rotating shaft, a limit column, a drill bit, a support plate, an electric push rod, and a bracket. The traction hook at one end of the shell is hung on agricultural equipment, and the shell is driven forward by the agricultural equipment. During the forward movement, a planting pit is dug. The device can work uninterruptedly during the movement of the vehicle, greatly reducing the non-productive time consumption, completing more hole-drilling tasks in the same time, improving the overall operation efficiency, and making it easier to control the spacing between plants to ensure that the seeds are evenly distributed according to the predetermined design, which is beneficial to the later management and crop growth. At the same time, by accurately controlling the drilling depth and diameter, unnecessary soil disturbance is reduced and the soil structure is protected. The device is particularly suitable for saline-alkali land, which has a high requirement for soil stability, and avoids the existing sowing machine from getting stuck or blocked during the trenching process due to the high hardness and compaction of the soil in the saline-alkali land, resulting in poor trenching effect and inconsistent sowing depth affecting the seed germination rate.

[0059] (2) The device and method for planting salsa salsa for repairing saline-alkali land are provided with a fan, a pipe, a storage hopper, a movable shaft, a baffle, an electromagnet, a magnet, a limit plate and a sealing plate. When the drilling bit reaches the specified depth, the salsa salsa seeds are transported to the inner cavity through the pipe and sprayed out from the discharge port and fall into the planting pit, thereby completing the sowing operation, avoiding multiple mechanical operations at the same location, reducing the number of times the equipment enters and exits the field, greatly improving work efficiency, and significantly shortening the time required for the entire planting process. This will bring huge time savings, especially in large-scale saline-alkali land repair projects. An appropriate amount of seeds are placed in each planting pit and the same sowing depth is maintained, thereby improving the germination rate of seeds and reducing the competitive growth problem caused by too many seeds. Moreover, since the sowing depth is more consistent, irrigation water can be more effectively absorbed by the seeds, reducing the waste of water resources.

[0060] (3) The device and method for planting saltwort for repairing saline-alkali land are provided with a guide column, a spring 1, a sleeve, a sliding plate, a driven plate, a limit rod, a spring 2, a guide rod, a spring 3, an extrusion plate, a toggle plate, an air bag, an extension plate, an air inlet pipe, a sealing box, a piston plate and a sliding rod. A sleeve is provided on the outside of the drill bit. After the planting pit is opened and sown, the toggle plate and the extension plate are used to cover the soil. The three steps of drilling, sowing and covering the soil are integrated into one continuous operation, which greatly improves the work efficiency and avoids the problems caused by uneven or inadequate covering of the soil. It can ensure that the seeds in each planting pit are uniformly covered, promote water absorption and root development, which helps to improve the seed germination rate and the consistency of seedling growth, reduce the risk of seeds being exposed to the outside, and reduce the possibility of seed waste. The task can be completed while minimizing additional soil disturbance, avoiding the destruction of soil aggregate structure, maintaining the air permeability and water permeability of the soil, helping to maintain the soil structure, and reducing the probability of salt crust formation. It is particularly suitable for saline-alkali land, which has a high requirement for soil stability.

[0061] Other features and advantages of the present invention will be described in the following description, and part of them will become obvious from the description, or will be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the written description and the accompanying drawings.

[0079] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0080] See also Figures 1 to 16 , the present invention provides the following technical solutions:

[0081] Embodiment 1: A salsa salsa planting device for repairing saline-alkali land includes a housing 1 with a traction hook, a fixed contact 11 for controlling the activation of a planting component, and a follower contact 12 for cooperating with the fixed contact 11 to control the activation of the planting component. The fixed contact 11 is fixed to the inner side wall of the housing 1 through a connecting plate, and the follower contact 12 is fixedly mounted on the side wall of the bracket 3. A planting component for opening a planting pit is provided in the housing 1. The planting component includes: a power motor 2, an output shaft 21, a gear 1 22, a gear 23, a steel belt transmission unit 24, a drive motor 25, a rotating shaft 26, a limit column 261, a drill bit 27, a support plate 28, an electric push rod 29, and a bracket 3. The steel belt transmission unit 24 is composed of a steel belt, a transmission roller, and a transmission shaft.

[0082] One end of the bracket 3 is fixedly mounted on the steel belt transmission unit 24 to provide support for the components in the planting assembly;

[0083] The outer wall of the power motor 2 is fixedly mounted in the housing 1 through the motor box to drive the planting assembly to move;

[0084] One end of the output shaft 21 is fixedly mounted on the output end of the power motor 2 through a coupling to transmit the power required for the movement of the planting assembly;

[0085] Gear 1 22 is fixedly mounted on the output shaft 21 to transmit the power required for the movement of the planting assembly;

[0086] Gear 2 23 is meshed with gear 1 22 and is fixedly mounted on the transmission shaft of the steel belt transmission unit 24 to drive the steel belt transmission unit 24 to move.

[0087] The transmission shaft of the steel belt transmission unit 24 is movably mounted on a fixed plate through a bearing. The fixed plate is detachably mounted in the housing 1 through bolts to carry the planting assembly and keep the moving speed of the planting assembly consistent with that of the housing 1.

[0088] The outer wall of the driving motor 25 is fixedly mounted on the bracket 3 through the motor seat to provide power for opening the planting pit;

[0089] One end of the rotating shaft 26 is fixedly connected to the output end of the driving motor 25 through a coupling to transmit the power required to open the planting hole;

[0090] Both ends of the limiting post 261 are fixedly installed in the drill bit 27 to transmit the power required for the drill bit 27 to rotate. The limiting post 261 is slidably installed in the rotating shaft 26;

[0091] The inner wall of the drill bit 27 is sleeved outside the rotating shaft 26 and is driven by the driving motor 25 to open the planting hole;

[0092] One end of the support plate 28 is slidably inserted into the bracket 3, and the other end of the support plate 28 is movably sleeved on the outside of the drill bit 27 through a bearing to provide support for the drill bit 27;

[0093] One end of the electric push rod 29 is fixedly mounted on the bracket 3 , and the other end of the electric push rod 29 is fixedly mounted on the top of the support plate 28 to drive the support plate 28 to move up and down.

[0094] When in use, the traction hook at one end of the housing 1 is hung on the agricultural equipment, and the housing 1 is driven forward by the agricultural equipment. During the forward movement, the power motor 2 is started, and the output shaft 21 is driven to rotate by the power motor 2, and the output shaft 21 drives the gear 1 22 to rotate, and the gear 1 22 drives the gear 2 23 to rotate, and the gear 2 23 drives the steel belt transmission unit 24 to operate, and the steel belt transmission unit 24 drives the bracket 3 installed thereon to move, so that the bracket 3 drives the planting assembly installed thereon to move. During the movement of the planting assembly, the steel belt transmission unit 24 keeps the forward speed consistent with that of the housing 1;

[0095] When the bracket 3 drives the follower contact 12 to move to the position of the fixed contact 11, the drive motor 25 is started, and the drive motor 25 drives the rotating shaft 26 to rotate, and the rotating shaft 26 drives the limiting column 261 to rotate, and the limiting column 261 drives the drill bit 27 to rotate. At the same time, the electric push rod 29 is started, and the electric push rod 29 drives the support plate 28 to move to the side away from the steel belt transmission unit 24, so that the support plate 28 drives the drill bit 27 to move synchronously. Through the sliding cooperation between the limiting column 261 and the rotating shaft 26, the drill bit 27 synchronously drives the limiting column 26 in the process of moving downward. 1 moves downward, and the drill bit 27 can keep rotating, thereby breaking the hard crust on the surface of the saline-alkali land and drilling a planting hole, and breaking the compacted soil into small pieces. After the drill bit 27 drills to the specified depth, the drive motor 25 drives the rotating shaft 26 to rotate in the opposite direction, and at the same time the electric push rod 29 resets to the initial position, so that the drill bit 27 moves out of the drilled planting hole. During the operation of the previous drill bit 27, as the steel belt transmission unit 24 runs, the next bracket 3 equipped with the drill bit 27 reaches the fixed contact point 11, and the drilling operation of the next planting hole is immediately carried out.

[0096] Embodiment 2, the technical solution of this embodiment is different from that of embodiment 1 in that: a sowing assembly for dropping salsa salsa seeds is further provided in the housing 1, and the sowing assembly includes: a discharge port, a fan 4, a pipe 41, a storage hopper 42, a movable shaft 43, a baffle 44, an electromagnet 45, a magnet 46, a limit plate 47, and a sealing plate 48;

[0097] A discharge port is provided on the lower side wall of the drill bit 27 for feeding Suaeda salsa seeds;

[0098] The outer wall of the fan 4 is fixedly mounted on the bracket 3 through the outer shell.

[0099] One end of the pipe 41 is connected to the output end of the fan 4, and the other end of the pipe 41 is connected to the drill bit 27 to transport the saltwort seeds. One end of the pipe 41 is fixedly installed in the sealing plate 48.

[0100] The top of the storage hopper 42 is fixedly mounted on the bracket 3, and the bottom of the storage hopper 42 is connected to the pipeline 41 through the feed pipe. The storage hopper 42 is used to store the saltwort seeds.

[0101] One end of the movable shaft 43 is movably mounted on the inner wall of the drill bit 27 via a bearing;

[0102] One end of the baffle 44 is fixedly mounted on the side wall of the movable shaft 43 to control the opening and closing of the discharge port;

[0103] One end of the electromagnet 45 is fixedly mounted on the bottom of the inner wall of the drill bit 27;

[0104] The side wall of the magnet 46 is fixedly mounted on the side wall of the baffle 44, and the magnetic cooperation between the magnet 46 and the electromagnet 45 changes the position of the baffle 44;

[0105] One end of the limit plate 47 is fixedly mounted on the bottom of the inner wall of the drill bit 27 to limit the rotation angle of the baffle 44;

[0106] The outer wall of the sealing plate 48 is movably mounted in the drill bit 27 via a bearing to separate the inner cavity of the drill bit 27 .

[0107] During use, when the planting assembly is used to open a planting pit, after the drill bit 27 reaches the specified depth, the fan 4 is started and the solenoid valve is opened for 1-2 seconds, so that some saltwort seeds in the storage hopper 42 fall into the pipe 41 below, and are transported to the inner cavity formed between the inner wall of the drill bit 27 and the sealing plate 48 through the fan 4 and the pipe 41. When the solenoid valve is closed, the electromagnet 45 is controlled to be energized, so that the magnetism of the electromagnet 45 and the magnet 46 repel each other, and the magnet 46 drives the baffle 44 to move. The baffle 44 rotates around the movable shaft 43 and is limited by the limit plate 47 to limit the rotation angle of the baffle 44, so that the inner cavity is connected with the planting pit. At this time, the saltwort seeds are just transported to the inner cavity through the pipe 41 and sprayed out from the discharge port and fall into the planting pit. Then the magnetism of the electromagnet 45 is changed again, so that the electromagnet 45 and the magnet 46 are magnetically attracted to each other, so that the magnet 46 drives the baffle 44 to flip and reset again around the movable shaft 43 as the axis. After the baffle 44 is reset, the fan 4 is controlled to be turned off, and the drill bit 27 is withdrawn from the opened planting pit, thereby completing the sowing operation.

[0108] Embodiment 3: This embodiment differs from the embodiment 2 in that: a covering assembly for covering the planting hole with soil after sowing is further provided in the housing 1, and the covering assembly includes: a guide column 210, a spring 1 211, a sleeve 5, a sliding plate 51, a driven plate 52, a limiting rod 53, and a spring 2 54;

[0109] One end of the guide post 210 is fixedly mounted on the top of the support plate 28, and one end of the guide post 210 slides out from the fixing ear of the sleeve 5. One end of the spring 1 211 is fixedly mounted on the top of the sleeve 5, and the other end of the spring 1 211 is fixedly mounted on the bracket 3;

[0110] The end of the sleeve 5 away from the electric push rod 29 is slidably inserted into the bracket 3, and the sleeve 5 is entirely sleeved outside the drill bit 27 to change the scattering range of the loose soil during the excavation of the planting pit;

[0111] One end of the sliding plate 51 is provided with an inclined surface, and the other end of the sliding plate 51 is fixedly mounted on the support plate 28;

[0112] One end of the driven plate 52 is provided with an inclined surface that is slidably adapted to the sliding plate 51, and the other end of the driven plate 52 slides out of the sleeve 5;

[0113] One end of the limiting rod 53 is fixedly mounted on the outside of the sleeve 5, and the other end of the limiting rod 53 slides out of the driven plate 52 to limit the moving direction of the driven plate 52;

[0114] One end of the second spring 54 is fixedly mounted on the limiting rod 53, and the other end of the second spring 54 is fixedly mounted on the driven plate 52 to provide elastic force for returning the driven plate 52;

[0115] The soil covering assembly also includes: a guide rod 55, a spring 56, an extrusion plate 57, a toggle plate 58, an air bag 59, an extension plate 510, an air inlet pipe 511, a sealing box 512, a piston plate 513, and a sliding rod 514;

[0116] The top of the guide rod 55 is fixedly mounted on the bottom of the driven plate 52;

[0117] One end of the spring 3 56 is fixedly mounted on the guide rod 55 , and the other end of the spring 3 56 is fixedly mounted on the extrusion plate 57 ;

[0118] The extrusion plate 57 is slidably mounted on the guide rod 55 to provide power for covering the soil;

[0119] A mounting shaft is fixedly provided on the inner wall of the toggle plate 58, and the mounting shaft is movably hinged to the sleeve 5 through a worm spring for covering soil operation;

[0120] One end of the air bag 59 is fixedly mounted in the toggle plate 58;

[0121] One end of the extension plate 510 is fixed to the air bag 59, and the other end of the extension plate 510 slides out from the toggle plate 58 to assist in the covering operation;

[0122] One end of the air inlet pipe 511 is connected to the air bag 59, and the other end of the air inlet pipe 511 is connected to the sealing box 512. The bottom of the sealing box 512 is fixedly mounted on the top of the sleeve 5.

[0123] The outer wall of the piston plate 513 is slidably mounted in the sealing box 512;

[0124] One end of the sliding rod 514 is fixedly mounted on the piston plate 513 , and the other end of the sliding rod 514 slides out of the sealing box 512 and is finally fixedly mounted on the bracket 3 .

[0125] When in use, a sleeve 5 is provided on the outside of the drill bit 27;

[0126] During the drilling process of the drill bit 27, the support plate 28 drives the sealing plate 48 to move downward synchronously, and the bracket 3 provides support force to the sliding rod 514, and the sliding rod 514 provides support force to the piston plate 513. The sealing plate 48 moves downward while the sliding rod 514 and the piston plate 513 do not move, so that the piston plate 513 and the sealing plate 48 move relative to each other, so that the air in the airbag 59 is transported to the sealing plate 48 through the air inlet pipe 511, causing the airbag 59 to deflate, driving the extension plate 510 to retract a short distance into the inside of the toggle plate 58;

[0127] When the drill bit 27 completes drilling and moves upward, the air in the sealing plate 48 is transported to the air bag 59 through the air inlet pipe 511, causing the air bag 59 to expand, driving the extension plate 510 to extend outward from the toggle plate 58;

[0128] As the drill bit 27 moves upward, the support plate 28 will simultaneously drive the sliding plate 51 to move upward. During the upward movement, the sliding plate 51 slides and abuts against one end of the driven plate 52, causing the driven plate 52 to move away from the sliding plate 51 under the squeezing of the sliding plate 51.

[0129] During the movement, the driven plate 52 can only move linearly along the limiting rod 53 due to the sliding fit between the driven plate 52 and the limiting rod 53, so that the extrusion plate 57 no longer exerts an extrusion force on the toggle plate 58. Under the action of the worm spring, the toggle plate 58 flips toward the outer position of the sleeve 5 with the mounting axis as the axis.

[0130] The second spring 54 provides an elastic force to the driven plate 52 toward the side where the sleeve 5 is located, so that the sliding plate 51 can move toward the side where the sleeve 5 is located after the sliding plate 51 is separated from the driven plate 52. Figure 15 The spring 3 56 provides an elastic force to the squeeze plate 57 toward the side where the sleeve 5 is located, so that the squeeze plate 57 can also move to the side where the sleeve 5 is located after the sliding plate 51 and the driven plate 52 are separated under the action of the spring 3 56. Figure 15 The position shown is reset;

[0131] The extrusion plate 57 squeezes the toggle plate 58, so that the toggle plate 58 drives the extension plate 510 to flip toward the center position of the sleeve 5 with the installation axis as the axis. Through the cooperation between the toggle plate 58 and the extension plate 510, the soil scattered during the drilling of the planting pit is pushed back into the planting pit, thereby covering the sown saltwort seeds.

[0132] In another embodiment different from the previous embodiment, a set of transmission gears is added and meshed with gear 1 22. The added transmission gears are installed on the movable shaft at the bottom of the shell 1, so that the power motor 2 drives the steel belt transmission unit 24 to operate, and synchronously drives the shell 1 to move.

[0133] An embodiment of the present invention further provides a planting method for a Suaeda salsa planting device for repairing saline-alkali land, comprising the following steps:

[0134] S1. Perform preparatory work by transferring the housing 1 to the saline-alkali land where Suaeda salsa is to be sown, loading the Suaeda salsa seeds into the sowing assembly, and then connecting the housing 1 to the agricultural equipment for driving;

[0135] S2, starting the agricultural equipment to drive the housing 1 forward;

[0136] S3, starting the planting component to open a planting pit. After the planting pit is opened, the sowing component sows the seeds of Suaeda salsa into the planting pit;

[0137] S4. After the seeds are sown, the soil covering component is used to cover the floating soil to the planting pit;

[0138] S5. Use irrigation equipment to properly water and fertilize the planting pit

[0139] The speed at which the power motor 2 in the planting assembly drives the steel belt transmission unit 24 is between 25s / m and 50s / m.
