An automatic water replenishing device and method for forestry planting and seedling raising

Abstract

The invention discloses an automatic water replenishing device for forestry planting and seedling cultivation, which belongs to the technical field of forestry water replenishing. The following scheme is proposed, which includes a hollow half ring, and the hollow half ring is symmetrically provided with two groups. In the invention, when the water in the hollow column evaporates, the water volume will be reduced, so that the hollow floating block will drop as the liquid level drops. When the secondary contact switch contacts the hollow floating block, it indicates that the water volume evaporates more and the seedling needs to be watered. When water is replenished, the concave receiving ring receives part of the water liquid that has leaked into the soil and guides it into the hollow column. As the water in the hollow column increases, the hollow floating block floats up. When the hollow floating block contacts the primary contact switch, it indicates that the water replenishment volume reaches the standard and the water replenishment is stopped. When water is replenished, the seedling is fixed by the anti-tilting module, so that the seedling is not easy to tilt due to the collapse of the soil due to water replenishment. After water replenishment, the soil is compacted by the compacting module to prevent the soil from loosening and collapsing due to water replenishment, thereby ensuring that the seedling is upright.

[0015] The guide plate has a V-shaped structure, and the top of the guide plate is an inclined structure, and the bottom of the guide plate is a flat structure. The inclined surface can better guide the water to the seedlings in the center of the device to prevent the water from spraying directly on the soil.

[0016] Preferably, the compaction module further includes a first-level transverse plate member, a first-level sleeved frame plate, a first-level lifting plate member, a mounting plate member, a first-level driving motor, and a driving lead screw.

The limiting notch is opened in the abutting plate, and the limiting notch is communicated with the sliding notch. The limiting plate member is slidably fitted in the limiting notch, and the limiting plate member is connected to the sliding plate member. The gear rotates, cooperating with the teeth meshed with the gear, causing the rotating semi-ring to drive the rotating plate member to rotate. Under the limitation of the track notch, the linkage rod member drives the outer sleeve rod member to move towards the center of the hollow semi-ring until the abutting plate presses tightly against the sapling, keeping the sapling in a vertical state and making it not easy for the sapling to tilt due to the collapse caused by soil water replenishment;

[0019] A first-level blocking semi-ring is connected to the top edge of the hollow semi-ring. A second-level blocking semi-ring is connected to the top of the first-level blocking semi-ring.

The gear is arranged on the left side of the hollow column, and the gear is meshed and connected with the tooth teeth.

The longitudinal plate member is connected to the right side of the water storage tank. The pump body is fixedly connected to the top end of the longitudinal plate member through positioning bolts. The hose is communicated between the right side of the pump body and the hollow semi-ring. The top end of the conduit penetrates through the longitudinal plate member and is communicated with the pump body. The bottom end of the conduit is communicated with the bottom of the right side of the water storage tank. When the pump body is turned on, the water liquid in the water storage tank is guided into the hollow semi-ring through the conduit and the hose;

[0023] An observation window is arranged on the front side of the water storage tank, facilitating personnel to timely replenish the water liquid in the water storage tank.

[0024] The usage method of the automatic water replenishing device for forestry planting and seedling raising includes the following steps:

[0025] S1. Bury the concave receiving ring in the soil, plant the sapling in the middle of the concave receiving ring, use the primary assembly plate members to connect and fix the two groups of hollow semi-rings, and use the secondary assembly plate members to connect and fix the two groups of rotating semi-rings to complete the installation of the water replenishing device;

[0026] S2. Before water replenishment, the water in the hollow column evaporates, which will reduce the amount of water, so that the hollow float will drop as the liquid level drops. When the secondary contact switch contacts the hollow float, it means that a lot of water has evaporated, so it is determined that there is less water in the soil and the sapling needs to be watered. At this time, the secondary contact switch transmits a signal to the peripheral terminal, which receives the signal and controls the secondary drive motor and the pump body to start. The output shaft at the bottom of the secondary drive motor drives the gear to rotate, and cooperates with the teeth meshing with the gear to make the rotating half ring drive the rotating plate to rotate. Under the restriction of the track slot, the linkage rod drives the outer sleeve rod to move toward the center of the hollow half ring until the plate is pressed against the sapling, so that the sapling remains in a vertical state, so that the sapling is not easily tilted due to the collapse of the soil water replenishment.

[0027] S3. At the same time, the pump body is opened to spray the water in the water tank through the conduit, hose, hollow half ring and nozzle to the inclined surface at the top of the guide plate. The inclined surface can better guide the water to the sapling in the center of the device to prevent the water from being sprayed directly on the soil. After the water flows into the soil, it will gradually seep down. When part of the water seeps into the concave receiving ring, it will flow into the connecting rod and enter the hollow column through the liquid inlet. The water gradually accumulates at the bottom of the inner cavity of the hollow column, causing the hollow float to rise with the rise of the water. When the hollow float rises and contacts with the primary contact switch, the primary contact switch transmits a signal to the peripheral terminal. The peripheral terminal receives the signal and controls the pump body to close, thereby completing the water replenishment of the sapling.

[0028] S4, while the peripheral terminal controls the pump body to be closed, it controls the first-level driving motor to be turned on, and the first-level driving motor drives the driving screw to rotate, so that the first-level lifting plate and the second-level lifting plate are lowered, thereby driving the hollow semi-ring and the compacting semi-ring to be lowered. Since the abutment plate presses against the sapling, the sliding plate and the limiting plate are respectively slidably matched in the sliding groove and the limiting groove, and will be lowered with the descending of the outer sleeve rod, and the abutment plate will continue to press against the outside of the sapling under the action of friction. When the compacting semi-ring contacts with the soil, the force of the compacting semi-ring squeezing the soil is monitored by the pressure sensor. When the force of compacting the soil reaches a preset value, the pressure sensor transmits data to the peripheral terminal. The peripheral terminal receives the data and controls the first-level driving motor to drive the driving screw to reverse, so that the first-level lifting plate and the second-level lifting plate are raised, so that the compacting semi-ring is separated from the soil until the second-level lifting plate contacts with the anti-slip circular plate, and the first-level driving motor is turned off.

[0029] S5. When the primary drive motor is turned off, the peripheral terminal controls the secondary drive motor to turn on, causing the gear to rotate in the opposite direction, thereby separating the abutment plate from the sapling under the action of the rotating semi-ring, the rotating plate and the track notch, preventing the abutment plate from pressing against the sapling and affecting its growth.

[0030] Compared with the prior art, the present invention provides an automatic water supply device for forestry planting and seedling raising, which has the following beneficial effects:

[0031] 1. The automatic water replenishment device for forestry planting and seedling cultivation will reduce the amount of water when the water in the hollow column evaporates, so that the hollow float will drop as the liquid level drops. When the secondary contact switch contacts the hollow float, it indicates that a lot of water has evaporated, so it is determined that there is less water in the soil and the seedlings need to be watered. When water is replenished, the concave receiving ring receives part of the water that has leaked into the soil and guides it into the hollow column. As the amount of water in the hollow column increases, the hollow float floats up. When the hollow float contacts the primary contact switch, it indicates that the amount of water replenishment has reached the standard, and water replenishment is stopped, thereby The automatic watering function of the seedlings is realized during forestry seedling cultivation. During watering, the anti-tilt module fixes the seedlings so that the seedlings are not easily tilted due to soil collapse caused by watering. After watering, the compaction module compacts the soil to prevent the soil from becoming loose and collapsing due to watering, thereby ensuring that the seedlings are upright. Through this device, automatic watering is realized during planting and seedling cultivation, and the problem of soil collapse and seedling tilting during watering, as well as the need to compact the soil after watering, are integrated and combined with automatic watering, so that the watering device has a higher degree of automation and more comprehensive functions.

The setting of the secondary horizontal plate 519, the secondary sleeve frame plate 520 and the secondary lifting plate 521 enhances the stability of the rotating semi-ring 58 and the hollow semi-ring 1.

[0063] In the present invention, the water replenishment module 6 also includes a longitudinal plate 62, a pump body 63, a hose 64 and a conduit 65. The longitudinal plate 62 is connected to the right side of the water storage tank 61. The pump body 63 is fixedly connected to the top of the longitudinal plate 62 by a positioning bolt. The hose 64 is connected between the right side of the pump body 63 and the hollow half ring 1. The top of the conduit 65 passes through the longitudinal plate 62 and is connected to the pump body 63. The bottom end of the conduit 65 is connected to the bottom of the right side of the water storage tank 61. When the pump body 63 is opened, the water in the water storage tank 61 is introduced into the hollow half ring 1 through the conduit 65 and the hose 64.

[0064] An observation window is provided on the front side of the water storage tank 61 to facilitate personnel to replenish the water in the water storage tank 61 in time.

[0065] In the present invention, a method for using an automatic water replenishment device for forestry planting and seedling raising comprises the following steps:

[0066] S1. Bury the concave receiving ring in the soil, plant the sapling in the middle of the concave receiving ring, connect and fix the two sets of hollow half rings with the first-level assembly plate, and connect and fix the two sets of rotating half rings with the second-level assembly plate to complete the installation of the water supply device;

[0067] S2. Before water replenishment, the water in the hollow column evaporates, which will reduce the amount of water, so that the hollow float will drop as the liquid level drops. When the secondary contact switch contacts the hollow float, it means that a lot of water has evaporated, so it is determined that there is less water in the soil and the sapling needs to be watered. At this time, the secondary contact switch transmits a signal to the peripheral terminal, which receives the signal and controls the secondary drive motor and the pump body to start. The output shaft at the bottom of the secondary drive motor drives the gear to rotate, and cooperates with the teeth meshing with the gear to make the rotating half ring drive the rotating plate to rotate. Under the restriction of the track slot, the linkage rod drives the outer sleeve rod to move toward the center of the hollow half ring until the plate is pressed against the sapling, so that the sapling remains in a vertical state, so that the sapling is not easily tilted due to the collapse of the soil water replenishment.

[0068] S3. At the same time, the pump body is opened to spray the water in the water tank through the conduit, hose, hollow half ring and nozzle to the inclined surface at the top of the guide plate. The inclined surface can better guide the water to the sapling in the center of the device to prevent the water from being sprayed directly on the soil. After the water flows into the soil, it will gradually seep down. When part of the water seeps into the concave receiving ring, it will flow into the connecting rod and enter the hollow column through the liquid inlet. The water gradually accumulates at the bottom of the inner cavity of the hollow column, causing the hollow float to rise with the rise of the water. When the hollow float rises and contacts with the primary contact switch, the primary contact switch transmits a signal to the peripheral terminal. The peripheral terminal receives the signal and controls the pump body to close, thereby completing the water replenishment of the sapling.

[0069] S4, while the peripheral terminal controls the pump body to be closed, it controls the first-level driving motor to be turned on, and the first-level driving motor drives the driving screw to rotate, so that the first-level lifting plate and the second-level lifting plate are lowered, thereby driving the hollow semi-ring and the compacting semi-ring to be lowered. Since the abutment plate presses against the sapling, the sliding plate and the limiting plate are respectively slidably matched in the sliding groove and the limiting groove, and will be lowered with the descending of the outer sleeve rod, and the abutment plate will continue to press against the outside of the sapling under the action of friction. When the compacting semi-ring contacts with the soil, the force of the compacting semi-ring squeezing the soil is monitored by the pressure sensor. When the force of compacting the soil reaches a preset value, the pressure sensor transmits data to the peripheral terminal. The peripheral terminal receives the data and controls the first-level driving motor to drive the driving screw to reverse, so that the first-level lifting plate and the second-level lifting plate are raised, so that the compacting semi-ring is separated from the soil until the second-level lifting plate contacts with the anti-slip circular plate, and the first-level driving motor is turned off.

[0070] S5. When the primary drive motor is turned off, the peripheral terminal controls the secondary drive motor to turn on, causing the gear to rotate in the opposite direction, thereby separating the abutment plate from the sapling under the action of the rotating semi-ring, the rotating plate and the track notch, preventing the abutment plate from pressing against the sapling and affecting its growth.

[0071] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention should cover within the protection scope of the present invention any equivalent replacement or change made according to the technical solution and inventive concept of the present invention.

Before water replenishment, the water in the hollow column (32) evaporates, which reduces the amount of water, thereby causing the hollow float (33) to drop as the liquid level drops. When the secondary contact switch (35) contacts the hollow float (33), it indicates that a large amount of water has evaporated, thereby determining that the water content in the soil is low and the seedling needs to be watered. At this time, the secondary contact switch (35) transmits a signal to the peripheral terminal, which receives the signal and controls the secondary drive motor (518) and the pump body (63) to start. The output shaft at the bottom end of the secondary drive motor (518) drives the gear (517) to rotate, and cooperates with the teeth (59) meshing with the gear (517), so that the rotating half ring (58) drives the rotating plate (54) to rotate. Under the restriction of the track slot (55), the linkage rod (56) drives the outer rod (53) to move toward the center of the hollow half ring (1) until the plate (51) presses against the sapling, so that the sapling remains in a vertical state and is not easily tilted due to soil water replenishment and collapse; S3, at the same time, the pump body (63) is opened, and the water in the water storage tank (61) is sprayed onto the inclined surface at the top of the guide plate (44) through the guide tube (65), the hose (64), the hollow half ring (1) and the nozzle (2). The inclined surface better guides the water to the sapling in the center of the device to prevent the water from being sprayed directly on the soil. After the water flows into the soil, it will gradually seep downward. When part of the water seeps into the concave receiving ring (31), it will flow into the connecting rod (38) and enter the hollow column (32) through the liquid inlet (39). The water gradually accumulates at the bottom of the inner cavity of the hollow column (32), causing the hollow floating block (33) to rise with the rise of the water. When the hollow floating block (33) rises to contact the primary contact switch (34), the primary contact switch (34) transmits a signal to the external terminal. The external terminal receives the signal and controls the pump body (63) to close, thereby completing the water replenishment of the sapling. S4, the peripheral terminal controls the pump body (63) to be closed and controls the first-stage drive motor (49) to be turned on. The first-stage drive motor (49) drives the drive screw (410) to rotate, so that the first-stage lifting plate (47) and the second-stage lifting plate (521) are lowered, thereby driving the hollow half ring (1) and the compacting half ring (41) to be lowered. Since the push plate (51) is pressed against the sapling, the sliding plate (511) and the limiting plate (513) are respectively slidably matched in the sliding slot (510) and the limiting slot (512), and will be lowered as the outer rod (53) is lowered, and the push plate (51) will be pressed against the sapling under the action of friction. Continue to press against the outside of the sapling, and when the compacting half ring (41) contacts the soil, the force of the compacting half ring (41) squeezing the soil is monitored through the pressure sensor (42). When the force of compacting the soil reaches a preset value, the pressure sensor (42) transmits data to the external terminal, and the external terminal receives the data and controls the first-level driving motor (49) to drive the driving screw (410) to reverse, so that the first-level lifting plate (47) and the second-level lifting plate (521) rise, thereby separating the compacting half ring (41) from the soil, until the second-level lifting plate (521) contacts the anti-slip circular plate (411), and the first-level driving motor (49) is turned off; S5. When the primary drive motor (49) is turned off, the peripheral terminal controls the secondary drive motor (518) to turn on, causing the gear (517) to rotate in the opposite direction, so that the abutment plate (51) and the sapling are separated under the action of the rotating half ring (58), the rotating plate (54) and the track notch (55), thereby preventing the abutment plate (51) from pressing against the sapling and affecting the growth of the sapling.
