Description

Technical Field

[0001] The invention relates to the technical field of vegetable planting, in particular to a self-watering vegetable planting seedling bed and a seedling raising method thereof. Background Art

[0002] Vegetables are the main source of plant fiber for the human body and are one of the essential foods in a healthy diet. They can also provide a variety of vitamins and minerals necessary for the human body. With the continuous improvement of living standards, people's requirements for the quality of vegetables are also increasing day by day, and the demand for green vegetables is also growing accordingly. Seedling beds, as related equipment for green vegetable cultivation, are also receiving more and more attention. However, most of the seedling beds currently used for green vegetable cultivation rely mainly on manual operation for water replenishment, or the water replenishment structure is too complicated and the cost is high. For example, in order to enable the water replenishment mechanism to move horizontally and vertically to achieve better water replenishment coverage, two sets of drive mechanisms are often required, and two motors or other drives are used to drive the water replenishment mechanism to move. The increase in equipment cost has led to the high price of green vegetables to a certain extent, and the complexity of the structure often increases the probability of failure.

The water replenishment mechanism is arranged at the bottom of the longitudinal slide. Multiple longitudinal guide rods are staggered in sequence and arranged on both sides of the seedling bed body parallel to its length direction. The opposite ends of the longitudinal guide rods on both sides of the seedling bed body are inclined in the same direction. The side of the longitudinal guide rod away from its inclined direction guides it to move along the width direction of the seedling bed body by contacting with the longitudinal slide. There is a gap between the longitudinal guide rod and the side of the seedling bed body on the opposite side for the longitudinal slide to pass through.

[0006] Preferably, the water replenishment mechanism includes a spray head, which is rotatably connected to the bottom of the longitudinal slide, and a torsion spring 1 is provided between the spray head and the longitudinal slide, and a steering guide rod is provided at the bottom of the longitudinal guide rod, and the steering guide rod is tilted along the inclination direction of the longitudinal guide rod. When the longitudinal guide rod guides the longitudinal slide to move along the width direction of the seedling bed body, the steering guide rod contacts the spray head and guides it to rotate along the length direction parallel to the seedling bed body, and the torsion spring 1 keeps applying force to the spray head to approach the steering guide rod.

[0007] Preferably, a liquid supply pipeline is provided in the longitudinal slide and passes through the bottom and top surfaces thereof, the bottom end of the liquid supply pipeline is connected to the sprinkler head through a hose, and the top end of the liquid supply pipeline is connected to the liquid supply equipment through a hose.

[0008] Preferably, a pressure sensor and an increasing pump are sequentially provided at the top of the liquid supply pipeline from top to bottom.

[0009] Preferably, a stopper 1 is provided at the bottom of the longitudinal slide on the side of the spray head tilting toward the longitudinal guide rod, and the stopper 1 is higher than the steering guide rod.

[0010] Preferably, a connecting rod is provided at the last gap along the inclination direction of the longitudinal guide rod, an outlet for the longitudinal slide to pass through is provided at the position of the connecting rod corresponding to the side of the seedling bed body close to the connecting rod, an entrance for the longitudinal slide to pass through is provided at the side of the opening corresponding to the first longitudinal guide rod along the inclination direction of the longitudinal guide rod, a limiting member is provided between the outlet and the entrance, a channel for the longitudinal slide to pass through is provided between the limiting member and the side of the seedling bed body, and a door structure is provided at the entrance for the longitudinal slide to pass through the entrance channel in one direction from the outlet to the entrance.

[0011] Preferably, the door structure includes a baffle, one side of the baffle is rotatably connected to the side of the inlet facing the outlet, and a second block cooperating with the baffle is provided at the side of the limiter facing the seedling bed body corresponding to the inlet. The baffle is located on the side of the second block away from the outlet, and a second torsion spring is provided between the baffle and the inlet. The second torsion spring maintains a force applied to the baffle toward the second block, and when the baffle contacts the block, the side of the baffle connected to the inlet tilts toward the outlet.

[0012] Preferably, a roller capable of rolling with the longitudinal guide rod is provided on the side of the longitudinal slide facing the inclination direction of the longitudinal guide rod.

[0013] Preferably, the bottom nozzle of the spray head includes a plurality of spray holes evenly arranged along the length direction of the seedling bed body.

[0014] The method for raising seedlings in the self-watering vegetable planting seedling bed as described above comprises the following steps:

[0015] S1. When water replenishment is needed, the transverse movement mechanism is started to drive the longitudinal rod to move along the length direction of the seedling bed body, so that the longitudinal slide is in contact with the longitudinal guide rod. While the longitudinal slide moves along the length direction of the seedling bed body, the longitudinal guide rod guides the longitudinal slide to move along the width direction of the seedling bed body, and the spraying angle of the sprinkler head is changed by the steering guide rod. When the longitudinal slide moves along the width direction of the seedling bed body, the spraying area of ​​the sprinkler head also moves along the width of the seedling bed body;

[0016] S2, driving the longitudinal slide along the longitudinal guide rod to the gap through the transverse movement mechanism, so that the longitudinal slide passes through the gap and cooperates with the next longitudinal guide rod until it enters the last gap;

[0017] S3, start the transverse movement mechanism to drive the longitudinal rod to move in the reverse direction along the length direction of the seedling bed body, so that the longitudinal slide is reset to prepare for the next water replenishment.

[0018] The beneficial effects of the present invention are:

[0019] 1. The cooperation of the transverse movement mechanism and the longitudinal movement mechanism can realize the movement of the longitudinal slide along the length direction and width direction of the seedling bed body respectively. It is only necessary to provide power drive to the transverse movement mechanism, which reduces the equipment cost;

[0020] 2. The longitudinal slide moves along the length direction of the seedling bed body, and at the same time, it moves along the width direction of the seedling bed body by sliding with the longitudinal rod under the limitation of the inclined longitudinal guide rod. When it moves to the end of the longitudinal guide rod, it enters the gap and cooperates with the next guide rod to achieve reciprocating motion in the width direction of the seedling bed body, and finally completes the irrigation and water replenishment of the entire seedling bed by the sprinkler head;

[0021] 3. As the longitudinal slide cooperates with the longitudinal guide rod, its position along the length of the seedbed body will also change when the longitudinal slide moves. To avoid the occurrence of irrigation blind spots due to this change, a steering guide rod that cooperates with the sprinkler head is set below the longitudinal guide rod. When the longitudinal slide cooperates with the longitudinal guide rod, the steering guide rod cooperates with the sprinkler head. When the sprinkler head follows the movement of the longitudinal slide, the steering guide rod will gradually change the angle of the sprinkler head. When the sprinkler head moves along the width direction of the seedbed body, the irrigated area is consistent with the width direction of the seedbed body, avoiding irrigation blind spots.

[0022] 4. After the longitudinal slide cooperates with the last longitudinal guide rod, it will enter the channel between the limiter and the seedling bed from the exit through the guidance of the connecting rod. After the longitudinal slide enters the channel, the transverse movement mechanism is controlled to drive the longitudinal rod to move in the opposite direction along the length direction of the seedling bed body for reset. Due to the loss of the limitation of the longitudinal guide rod, the longitudinal slide moves along the channel to the entrance and pushes the baffle. After passing the baffle, it can be reset for the next water replenishment, forming a cyclic operation.

[0023] 5. The baffle forms a one-way passage restriction through the cooperation of torsion spring 2 and block 2. When water is needed, the baffle can prevent the longitudinal slide from passing through the baffle and entering the channel between the limit piece and the seedling bed, and guide the longitudinal slide through the inlet to the longitudinal guide rod for water replenishment.

[0031] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0032] Example

[0033] In the vegetable planting process, water replenishment and irrigation are very important links, and the same is true for using seedling beds to plant green vegetables. At present, most seedling beds rely on manual or automatic water replenishment. Manual water replenishment is labor-intensive and labor-intensive, but the design ideas of some automatic water replenishment methods are relatively simple. For example, a horizontal motion mechanism and a vertical motion mechanism are used to drive the water replenishment mechanism to move horizontally and vertically respectively. First, the vertical movement irrigates a strip area, then the horizontal movement is a certain distance, and then the vertical movement in the opposite direction is used to irrigate a strip area. This reciprocating motion path similar to an S-shaped motion path is formed to complete the irrigation of the entire seedling bed. The above structural design makes the circuit part more complicated, which makes the cost of the seedling bed higher, which is not conducive to the promotion and use of the seedling bed.

[0034] In order to reduce the cost of the seedling bed, the present embodiment provides a self-watering seedling bed for vegetable planting, including a seedling bed body, wherein the seedling bed body is provided with a water replenishing mechanism, a longitudinal movement mechanism and a transverse movement mechanism, and the seedling bed body is provided with a transverse movement mechanism on one side parallel to its length direction, and the longitudinal movement mechanism cooperates with the transverse movement mechanism to drive the water replenishing mechanism to move along the width direction of the seedling bed body; the longitudinal movement mechanism includes a longitudinal rod, a longitudinal slide and a longitudinal guide rod, one end of the longitudinal rod is connected to the transverse movement mechanism and can be driven by the transverse movement mechanism to move along the length direction of the seedling bed body, The slide is slidably connected to the longitudinal rod and can move on the longitudinal rod along the width direction of the seedling bed body. The water replenishment mechanism is arranged at the bottom of the longitudinal slide. Multiple longitudinal guide rods are staggered in sequence and arranged on both sides of the seedling bed body parallel to its length direction. The opposite ends of the longitudinal guide rods on both sides of the seedling bed body are inclined in the same direction. The side of the longitudinal guide rod away from its inclined direction guides it to move along the width direction of the seedling bed body by contacting the longitudinal slide. There is a gap between the longitudinal guide rod and the side of the seedling bed body on the opposite side for the longitudinal slide to pass through.

[0035] The seedling bed of the present embodiment is characterized in that the length direction of the seedling bed body is the horizontal direction, and the width direction is the longitudinal direction. Among the transverse and longitudinal mechanisms, only the transverse mechanism requires circuit control. The transverse mechanism can be implemented in the form of a screw nut or a linear module. In the present embodiment, the screw nut is preferably in the form of a screw nut. The screw is connected to the servo motor and driven to rotate by the servo motor. The longitudinal rod is connected to the screw through the nut. The screw is arranged along one transverse side of the seedling bed body, and a limit rod is arranged on the other transverse side of the seedling bed body. The other end of the longitudinal rod is slidably connected to the limit rod. For example, a through hole is provided at the other end of the longitudinal rod, and the limit rod passes through the through hole. The longitudinal rod and the limit rod are slidably connected through the through hole. Under the restriction of the limit rod, the screw can drive the longitudinal rod to move transversely along the seedling bed body when it rotates, that is, it drives the longitudinal rod to move transversely. The direction of transverse movement depends on the rotation direction of the screw.

[0036] One of the rotation directions of the screw rod is set to forward rotation, and the other rotation direction is set to reverse rotation. One end of the longitudinal guide rod can be directly connected to the frame on the lateral side of the seedling bed body, or fixed through an additional frame, such as directly connected to the frame on the lateral side of the seedling bed body. The frames on both lateral sides of the seedling bed can be extended outward on both sides and then extended upward to provide installation space to prevent the components from contacting the vegetables. There is a gap between the other side of the longitudinal guide rod and the frame of the seedling bed body for the longitudinal slide to pass through. The inclination direction of the end of the longitudinal guide rod with the gap between it and the frame of the seedling bed body is set to be the forward direction of the longitudinal rod's lateral movement, and the opposite direction is the reverse direction of the longitudinal rod's lateral movement. When the screw rod rotates forward, the longitudinal rod moves forward, and when the screw rod rotates reversely, the longitudinal rod moves reversely. When replenishing water, the servo motor is activated to drive the screw to rotate in the forward direction, driving the longitudinal rod to move horizontally in the forward direction. The longitudinal slide contacts the side of the longitudinal guide rod facing the reverse direction. Due to the inclined setting of the longitudinal guide rod, under its restriction, the longitudinal slide will move in the longitudinal direction of the seedling bed body, that is, move into the gap between the longitudinal guide rod and the frame of the seedling bed body, so that the longitudinal slide moves longitudinally while moving horizontally. Under the cooperation of the transverse and longitudinal movement mechanisms, the water replenishment mechanism passes through each longitudinal guide rod and gap in sequence, and is driven by the longitudinal slide to move along multiple reverse-staggered V-shaped paths to complete the irrigation and water replenishment of the entire seedling bed.

[0037] The longitudinal slide can be composed of a sliding sleeve and a columnar base. The sliding sleeve is mounted on the longitudinal rod and is slidably connected to the longitudinal rod, while the columnar base is arranged at the bottom of the sliding sleeve. The base is set in a columnar shape to reduce the contact area with the longitudinal rod and reduce friction. The columnar shape is more symmetrical and can be smoothly guided no matter which side of the longitudinal guide rod it contacts.

[0038] During the irrigation and water replenishment process of the water replenishment mechanism, since it moves along a V-shaped path, if the irrigation angle of the water replenishment mechanism remains unchanged, an irrigation blind area may be formed at the end farther away from both sides of the V-shaped path. If the lateral irrigation range of the water replenishment mechanism along the seedling bed body is increased so that it can simultaneously cover the end farther away from both sides of the V-shaped path, repeated irrigation will occur at the end where the adjacent V-shaped path is closer, resulting in uneven irrigation of the entire seedling bed body.

[0039] In order to solve the above-mentioned problem of uneven irrigation, in one embodiment, the water replenishment mechanism includes a sprinkler head, which is rotatably connected to the bottom of the longitudinal slide, and a torsion spring 1 is provided between the sprinkler head and the longitudinal slide, and a steering guide rod is provided at the bottom of the longitudinal guide rod, and the steering guide rod is tilted along the inclination direction of the longitudinal guide rod. When the longitudinal guide rod guides the longitudinal slide to move along the width direction of the seedling bed body, the steering guide rod contacts the sprinkler head and guides it to rotate along the length direction parallel to the seedling bed body, and the torsion spring 1 keeps applying force to the sprinkler head to approach the steering guide rod.

[0040] Two ear plates arranged transversely along the bottom of the longitudinal slide can be set along the bottom of the longitudinal slide. The sprinkler head is located between the two ear plates, and rotating shafts are respectively set on both sides of the sprinkler head. The rotating shafts are rotatably connected to the ear plates, thereby realizing the rotational connection between the sprinkler head and the longitudinal slide.

[0041] The same principle applies to the columnar base, so the sprinkler head can also be set in a columnar shape.

[0042] Compared with the longitudinal guide rod, the steering guide rod has the same inclination direction but a smaller inclination angle, so that when the sprinkler head moves longitudinally, the steering guide rod contacts the sprinkler head and changes the angle between the sprinkler head and the horizontal plane where the seedling bed body is located. When the longitudinal slide moves along the longitudinal guide rod, the steering guide rod pushes the sprinkler head to rotate in the opposite direction of the longitudinal rod to compensate for the distance difference formed in the lateral direction when the sprinkler head moves along the V-shaped path. When passing through the gap, the torsion spring 2 drives the sprinkler head to reset.

[0043] In order to reduce the pipeline interference caused by the movement of the sprinkler head, in one embodiment, a liquid supply pipeline is provided in the longitudinal slide table, which runs through its bottom and top surfaces. The bottom end of the liquid supply pipeline is connected to the sprinkler head through a hose, and the top end of the liquid supply pipeline is connected to the liquid supply equipment through a hose.

[0044] The liquid supply equipment connects to the sprinkler heads via a liquid supply pipeline within the longitudinal slide. This pipeline is fixed within the slide to prevent interference with moving components and enhance overall structural stability. The liquid supply equipment supplies liquid to the sprinkler heads. This liquid can be water alone, a nutrient solution, or a pharmaceutical solution. This allows for not only hydration but also nutritional supplementation and pesticide application, depending on actual needs.

[0045] Since the liquid supply equipment needs to transport the liquid to the sprinkler head over a certain distance, in one embodiment, a pressure sensor and an increasing pump are provided at the top of the liquid supply pipeline from top to bottom. The pressure sensor is used to detect the hydraulic pressure near the sprinkler head. If the hydraulic pressure is insufficient, the pressure can be increased by the increasing pump. Of course, the pressure sensor and the increasing pump are set according to demand and are not necessary components.

[0046] The bottom of the longitudinal slide is located on the side where the spray head is inclined toward the longitudinal guide rod, and a stopper is provided. The stopper is higher than the steering guide rod, and the bottom end of the spray head is lower than the ear plate and the baffle and can contact the steering guide rod. The torsion spring keeps applying a force to the spray head toward the stopper. The stopper can be provided between the two ear plates at the bottom of the longitudinal slide and can be integrally formed with the two ear plates. When the longitudinal slide is located in the gap, the spring pushes the spray head to contact the stopper for reset. The position of the stopper can be set so that the spraying direction of the spray head is perpendicular to the seedling bed body at this time.

[0047] To facilitate the reset of the sprinkler head after water replenishment, in one embodiment, a connecting rod is provided at the last gap along the inclined direction of the longitudinal guide rod, and an outlet for the longitudinal slide to pass through is provided at the position corresponding to the connecting rod on the side of the seedling bed body close to the connecting rod, and an inlet for the longitudinal slide to pass through is provided on the side of the opening of the seedling bed body corresponding to the first longitudinal guide rod along the inclined direction of the longitudinal guide rod, a limiting member is provided between the outlet and the inlet, and a channel for the longitudinal slide to pass through is provided between the limiting member and the side of the seedling bed body, and a door structure is provided at the inlet for the longitudinal slide to pass through the inlet channel in one direction from the outlet to the inlet.

[0048] The number of longitudinal guide rods on both sides of the seedling bed body is equal. An inlet is provided at the junction of the first longitudinal guide rod and the seedling bed frame in the direction of forward movement of the longitudinal rods, facing the direction of reverse movement of the longitudinal rods. A connecting rod is provided in the gap between the last longitudinal guide rod and the seedling bed body in the direction of forward movement of the longitudinal rods. The connecting rod can be arranged along the length of the last longitudinal guide rod, and its inclination angle can be consistent or inconsistent with that of the last longitudinal guide rod, as long as it ensures continued forward lateral movement of the longitudinal slide. The connecting rod can be independent or integrally formed with the last longitudinal guide rod, meaning that the length of the last longitudinal guide rod should be greater than that of the other longitudinal guide rods. To better guide the longitudinal slide, the connecting rod preferably extends to contact the inner side of the seedling bed frame. An outlet is provided at the junction of the seedling bed frame and the connecting rod, facing the direction of reverse movement of the longitudinal rods. When water replenishment is completed, the connecting rod guides the forward lateral movement of the longitudinal slide through the outlet. The servo motor then controls the screw to rotate in the opposite direction, causing the longitudinal slide to return to its original position. In order to avoid the longitudinal slide being unable to contact the first longitudinal guide rod when replenishing water again, causing the longitudinal slide to move horizontally outside the frame of the seedling bed body, a channel is formed by setting a limit piece and the frame of the seedling bed body. The limit piece can be a rod structure or a plate structure, which is arranged along the transverse direction of the seedling bed body. A door structure is set at the position of the channel in the entrance, which only allows the longitudinal slide to move horizontally in the reverse direction but not in the forward direction. The door structure also needs to be set along the length direction of the first longitudinal guide rod. Its inclination angle can be consistent with the inclination angle of the first longitudinal guide rod, or it can be inconsistent. As long as it can be ensured that the longitudinal slide can guide the longitudinal slide through the entrance on the side of the door structure that moves horizontally in the reverse direction toward the longitudinal rod, after passing through the entrance, the water replenishment working process is the same as the aforementioned water replenishment working process.

[0049] In order to realize the function of the above-mentioned door structure, in one embodiment, the door structure includes a baffle, one side of the baffle is rotatably connected to the side of the inlet facing the outlet, and a second block cooperating with the baffle is provided on the side of the limit member facing the seedling bed body corresponding to the inlet. The baffle is located on the side of the block 2 away from the outlet, and a second torsion spring is provided between the baffle and the inlet. The second torsion spring maintains a force applied to the baffle toward the block 2, and when the baffle contacts the block, the side of the baffle connected to the inlet tilts toward the outlet.

[0050] A groove can be opened on the side of the inlet facing the outlet, and an ear plate can be set on one side of the baffle, and a rotating shaft can be set on the upper and lower sides of the ear plate respectively. The ear plate is placed in the groove, and the rotating shafts on the upper and lower sides of the ear plate are respectively connected to the upper and lower sides of the groove. Then, a second torsion spring can be installed between the baffle and the frame of the seedling bed body. When the longitudinal slide moves forward and laterally through the baffle in the channel, it pushes the baffle to rotate. After passing the baffle, the baffle rotates under the action of the second torsion spring and stops after contacting the block. Due to the action of the block, when the longitudinal rod moves forward and laterally again, the longitudinal slide cannot push the block, but is guided by the block to move longitudinally until it contacts the first longitudinal guide rod. Of course, since the baffle is set at an angle, when its width is greater than the width of the channel, the second block can be omitted. Since the width of the baffle is greater, its rotation angle will naturally be limited by the channel.

[0051] In order to reduce the friction between the longitudinal slide and the longitudinal guide rod, in one embodiment, the side of the longitudinal slide facing the inclination direction of the longitudinal guide rod is provided with a roller that can roll with the longitudinal guide rod. The friction is greatly reduced through the rolling friction between the roller and the longitudinal guide rod.

[0052] In one embodiment, in order to improve the water replenishment irrigation efficiency, the bottom nozzle of the sprinkler head includes a plurality of spray holes evenly arranged along the length direction of the seedling bed body to increase the horizontal water replenishment irrigation range, thereby reducing the number of required longitudinal guide rods.

[0053] In the above embodiment, both the longitudinal rod and the longitudinal guide rod can adopt a telescopic rod structure to achieve length adjustment to adapt to seedling bed bodies of different widths, and a detachable connection method can be adopted between the longitudinal guide rod and the frame of the seedling bed body, such as through a nut connection or a snap connection.

[0054] The method for raising seedlings in the self-watering vegetable planting seedling bed as described above comprises the following steps:

[0055] S1. When water replenishment is needed, the transverse movement mechanism is started to drive the longitudinal rod to move along the length direction of the seedling bed body, so that the longitudinal slide is in contact with the longitudinal guide rod. While the longitudinal slide moves along the length direction of the seedling bed body, the longitudinal guide rod guides the longitudinal slide to move along the width direction of the seedling bed body, and the spraying angle of the sprinkler head is changed by the steering guide rod. When the longitudinal slide moves along the width direction of the seedling bed body, the spraying area of ​​the sprinkler head also moves along the width of the seedling bed body;

[0056] S2, driving the longitudinal slide along the longitudinal guide rod to the gap through the transverse movement mechanism, so that the longitudinal slide passes through the gap and cooperates with the next longitudinal guide rod until it enters the last gap;

[0057] S3, start the transverse movement mechanism to drive the longitudinal rod to move in the reverse direction along the length direction of the seedling bed body, so that the longitudinal slide is reset to prepare for the next water replenishment.

[0058] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.

8. The self-watering vegetable planting nursery bed according to claim 7, characterized in that: The bottom nozzle of the spray head includes a plurality of spray holes evenly arranged along the length direction of the seedling bed body.

9. The method for raising seedlings in a self-watering vegetable planting seedling bed according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1. When water replenishment is needed, the transverse movement mechanism is started to drive the longitudinal rod to move along the length direction of the seedling bed body, so that the longitudinal slide is in contact with the longitudinal guide rod. While the longitudinal slide moves along the length direction of the seedling bed body, the longitudinal guide rod guides the longitudinal slide to move along the width direction of the seedling bed body, and the spraying angle of the sprinkler head is changed by the steering guide rod. When the longitudinal slide moves along the width direction of the seedling bed body, the spraying area of ​​the sprinkler head also moves along the width of the seedling bed body; S2, driving the longitudinal slide along the longitudinal guide rod to the gap through the transverse movement mechanism, so that the longitudinal slide passes through the gap and cooperates with the next longitudinal guide rod until it enters the last gap; S3, start the transverse movement mechanism to drive the longitudinal rod to move in the reverse direction along the length direction of the seedling bed body, so that the longitudinal slide is reset to prepare for the next water replenishment.
