Description

Technical Field

[0001] This utility model relates to the field of irrigation equipment technology, specifically to an irrigation device for seedling cultivation in greenhouses. Background Technology

[0002] Greenhouses primarily utilize sunlight to raise the indoor temperature, providing a suitable growing environment for crops. However, due to the unique characteristics of the greenhouse environment, such as lower light intensity than the outside and uneven soil and air humidity, higher demands are placed on irrigation equipment.

[0003] A search revealed a utility model patent with Chinese patent publication number CN220831061U, which discloses an irrigation device for seedling cultivation in a greenhouse. The device includes a frame, a top frame, a slide groove and a linear motor mounted on the frame along the longer side of the frame, a slider slidably mounted on the slide groove, and multiple nozzles mounted on the slider. A rotating plate is rotatably mounted on the frame between the slide groove and the linear motor, and a pulley is mounted on the end of the rotating plate near the linear motor.

[0004] Currently, seedling cultivation in greenhouses often uses seedling trays for centralized seedling cultivation. To facilitate personnel movement, a certain passage is often reserved between multiple seedling trays. If the above-mentioned device is in use, the water flow cannot stop spraying when passing through the passage, and this part of the water will be consumed and cannot be utilized, which is not conducive to saving water resources. Utility Model Content

[0005] The purpose of this utility model is to provide an irrigation device for greenhouse seedling cultivation to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an irrigation device for greenhouse seedling cultivation, comprising two guide rails and a mounting frame, wherein the mounting frame is located at the top of the two guide rails, both guide rails and the mounting frame are fixedly connected to the frame of the greenhouse, the two guide rails are slidably fitted with the same mounting seat, a horizontally arranged conveyor belt is installed inside the mounting frame, the upper half of the mounting seat is fixedly fitted outside the conveyor belt, the mounting seat and the mounting frame are equipped with a triggering component, the triggering component includes a mounting sleeve fixedly connected to the top of the mounting seat, a control button is fixedly installed on the inner wall of the bottom of the mounting sleeve, and the control button is electrically connected to an external water supply device through a wire.

[0007] As a further preferred embodiment of this technical solution, a contact frame is slidably inserted into the top outer wall of the mounting sleeve. The contact frame can press the control button. A spring is sleeved on the outside of each of the two support rods of the contact frame, and the top of the contact frame is cylindrical.

[0008] As a further preferred embodiment of this technical solution, three fixing plates are fixedly connected to the outer wall of one end of the mounting frame, and a horizontally arranged bidirectional screw is fixedly connected between the three fixing plates. A screw sleeve is threaded at both ends of the bidirectional screw. A top plate one and a top plate two are placed on the outer wall of one end of the mounting frame. The top plate one and the top plate two are interlocked to form a whole, and both the top plate one and the top plate two are in contact with the outer wall of the mounting frame. The two screw sleeves are rotatably connected to the top plate one and the top plate two respectively through bearings, and the contact frame can fit in close contact with the whole formed by the top plate one and the top plate two.

[0009] This allows irrigation to stop when the mounting base moves to an empty position, reducing water consumption. It also allows for adjustment of the position and width of the two top plates according to site conditions, increasing the adaptability of the device. Twisting the screw sleeve causes it to rotate and move to one side along the double-ended screw. Since the first top plate is in contact with the outer wall of the mounting frame, it will not rotate with the first top plate, but it can be moved horizontally along the mounting frame. Then, the position of the second top plate is adjusted. Since the first and second top plates are interlocked, their movements are not affected by each other. When the mounting sleeve is moved close to the first top plate by the mounting base, its top contact frame will be pressed down by the first top plate. Then, pressing the control button at the end of the contact frame will stop the external water supply device from working. Then, the spring passes over the second top plate, and the compressed spring can move the contact frame up and no longer press the control button.

[0010] As a further preferred embodiment of this technical solution, a watering component is installed at the bottom of the mounting base. The watering component includes a limiting groove opened on the outer wall of the bottom of the mounting base. A movable seat is slidably inserted into the limiting groove, and a horizontally arranged spray pipe is fixedly connected to the bottom of the movable seat.

[0011] As a further preferred embodiment of this technical solution, an extension plate is fixedly connected to the bottom of the outer wall of one end of the mounting base. A drive rod is rotatably connected inside the extension plate via a bearing. A connecting rod is hinged to one end of the drive rod, and one end of the connecting rod is hinged to the movable base. A gear is coaxially fixed to one end of the drive rod shaft. A horizontally arranged rack is placed on the top of the extension plate, and the rack is fixedly connected to the greenhouse frame. The gear meshes with the rack.

[0012] As the mounting base moves, the extension plate and gear are also moved synchronously. The gear rotates under the meshing of the rack, and the drive rod is driven to rotate by the gear. The drive rod, through the connecting rod, can drive the moving base to move back and forth along the limiting groove, thereby making the pouring sufficiently uniform.

[0013] As a further preferred embodiment of this technical solution, each of the two guide rails is rotatably connected to multiple rollers via bearings, and all of the multiple rollers are in contact with the top wall of the mounting base.

[0014] As a further preferred embodiment of this technical solution, the mounting base consists of a main body and two sealing plates, and both sealing plates are detachably connected to the main body by bolts.

[0015] This utility model provides an irrigation device for greenhouse seedling cultivation, which has the following beneficial effects:

[0016] (1) By setting a trigger component, this utility model can stop watering when the mounting seat moves to a blank position, which is beneficial to reduce water consumption. It can also adjust the position and width of the two top plates according to the site conditions, which is beneficial to increase the adaptability of the device. Twisting the screw sleeve will cause the screw sleeve to rotate and move to one side along the double screw. Since the top plate one is attached to the outer wall of the mounting frame, it will not rotate with the top plate one, but it can be driven to move horizontally along the mounting frame. Then adjust the position of the other top plate two. Since the top plate one and the top plate two are in a state of mutual insertion, their movement is not affected by each other. When the mounting sleeve is driven by the mounting seat to approach the top plate one, its top contact frame will be squeezed down by the top plate one. Then the control button is pressed at the end of the contact frame. The control button will control the external water supply device to stop working. Then the spring passes over the top plate two. The compressed spring can drive the contact frame to move up and no longer squeeze the control button.

[0017] (2) By setting up the pouring component, the extension plate and gear will also be driven to move synchronously when the mounting base moves. The gear will rotate under the meshing of the rack and pinion, and the drive rod will be driven to rotate by the gear. The drive rod can drive the moving base to move back and forth along the limiting groove through the connecting rod, so that the pouring is sufficiently uniform. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 1 and Figure 3 As shown in this embodiment, a watering device for greenhouse seedling cultivation includes two guide rails 1 and a mounting frame 4. The mounting frame 4 is located at the top of the two guide rails 1. Both the two guide rails 1 and the mounting frame 4 are fixedly connected to the frame of the greenhouse. The two guide rails 1 are slidably fitted with the same mounting seat 2. A horizontally arranged conveyor belt is installed inside the mounting frame 4. The upper part of the mounting seat 2 is fixedly fitted outside the conveyor belt. When the conveyor belt inside the mounting frame 4 is started, the belt can drive the mounting seat 2 to move along the two guide rails 1. Subsequently, the water spray pipe installed at its bottom will also perform overall watering in the horizontal direction.

[0025] The bottom of the mounting base 2 is equipped with a watering component 6. The watering component 6 includes a limiting groove 601 opened on the outer wall of the bottom of the mounting base 2. A movable base 602 is slidably inserted into the limiting groove 601. A horizontally set spray pipe is fixedly connected to the bottom of the movable base 602. The spray pipe can be connected to an external water supply device through a hose.

[0026] An extension plate 603 is fixedly connected to the bottom of the outer wall of one end of the mounting base 2. A drive rod 605 is rotatably connected to the inside of the extension plate 603 via a bearing. A connecting rod 604 is hinged to one end of the drive rod 605. One end of the connecting rod 604 is hinged to the movable base 602. A gear 606 is coaxially fixed to one end of the drive rod 605's rotating shaft. A horizontally arranged rack 607 is placed on the top of the extension plate 603, and the rack 607 is fixedly connected to the greenhouse frame. The gear 606 meshes with the rack 607.

[0027] As the mounting base 2 moves, the extension plate 603 and the gear 606 are also driven to move synchronously. The gear 606 rotates under the meshing of the rack 607, and the drive rod 605 is driven to rotate by the gear 606. The drive rod 605 can drive the moving base 602 to move back and forth along the limiting groove 601 through the connecting rod 604, so that the watering is sufficiently uniform.

[0028] like Figure 2 and Figure 4 As shown, the mounting base 2 and the mounting bracket 4 are equipped with a trigger assembly 5. The trigger assembly 5 includes a mounting sleeve 506 fixedly connected to the top of the mounting base 2. A control button 509 is fixedly installed on the inner wall of the bottom of the mounting sleeve 506. The control button 509 is electrically connected to an external water supply device through a wire.

[0029] A contact frame 507 is slidably inserted into the top outer wall of the mounting sleeve 506. The contact frame 507 can press the control button 509. A spring 508 is sleeved on the outside of each of the two support rods of the contact frame 507, and the top of the contact frame 507 is cylindrical.

[0030] Three fixing plates 503 are fixedly connected to the outer wall of one end of the mounting bracket 4. A horizontally arranged bidirectional screw rod 504 is fixedly connected between the three fixing plates 503. A screw sleeve 505 is threaded at both ends of the bidirectional screw rod 504. A top plate 1 501 and a top plate 2 502 are placed on the outer wall of one end of the mounting bracket 4. The top plate 1 501 and the top plate 2 502 are interlocked to form a whole, and both the top plate 1 501 and the top plate 2 502 are in contact with the outer wall of the mounting bracket 4. Two screw sleeves 505 are rotatably connected to the top plate 1 501 and the top plate 2 502 respectively through bearings. The contact frame 507 can fit in close contact with the whole formed by the top plate 1 501 and the top plate 2 502.

[0031] Twisting the screw sleeve 505 causes it to rotate and move to one side along the bidirectional screw 504. Since the top plate 501 and the outer wall of the mounting bracket 4 are in contact, it will not rotate with the top plate 501, but it can be moved horizontally along the mounting bracket 4. Then, the position of the other top plate 502 is adjusted. Since the top plate 501 and the top plate 502 are in an interlocking state, their movement is not affected by each other. When the mounting sleeve 506 is moved close to the top plate 501 by the mounting base 2, the contact frame 507 at its top will be pressed down by the top plate 501. Then, the end of the contact frame 507 presses the control button 509. The control button 509 will control the external water supply device to stop working. Then, the spring 508 passes over the top plate 502. The compressed spring 508 can drive the contact frame 507 to move up and no longer press the control button 509.

[0032] like Figure 1 and Figure 2 As shown, both guide rails 1 are rotatably connected to multiple rollers 3 through bearings, and the multiple rollers 3 are all in contact with the top wall of the mounting base 2, so that the friction between the mounting base 2 and the guide rail 1 changes from sliding friction to rolling friction, which helps to reduce the stress on the conveyor belt.

[0033] like Figure 1 and Figure 2As shown, the mounting base 2 consists of a main body and two sealing plates, and both sealing plates are detachably connected to the main body by bolts. If the guide rail 1 needs to be removed, it can be easily done by simply removing the bolts on the outside of the sealing plate.

[0034] This utility model provides an irrigation device for greenhouse seedling cultivation, the specific working principle of which is as follows:

[0035] When the device is working, adjust the positions of the two top plates 501 according to the location and width of the reserved channel. Twist the screw sleeve 505, and the screw sleeve 505 will rotate and move to one side along the double-acting screw 504. Since the top plate 501 is attached to the outer wall of the mounting bracket 4, it will not rotate with the top plate 501, but it can be moved horizontally along the mounting bracket 4. Then adjust the position of the other top plate 502. Since the top plate 501 and the top plate 502 are interlocked, their movements are not affected by each other. When the mounting sleeve 506 is moved close to the top plate 501 by the mounting base 2, the contact frame 507 on its top will be pressed down by the top plate 501. Then, the end of the contact frame 507 presses the control button 509, and the control button 509 will control... When the external water supply device stops working, the spring 508 passes over the top plate 502. The compressed spring 508 can drive the contact frame 507 to move upward and stop pressing the control button 509, thus allowing the machine to continue working. Then, the conveyor belt inside the mounting frame 4 is started, and the belt can drive the mounting base 2 to move along the two guide rails 1. Then, the water spray pipe installed at its bottom will also water the entire machine in the horizontal direction. While the mounting base 2 moves, the extension plate 603 and the gear 606 will also be driven to move synchronously. The gear 606 will rotate under the meshing of the rack 607. The drive rod 605 is driven by the gear 606 to rotate. The drive rod 605 can drive the moving base 602 to move back and forth along the limit groove 601 through the connecting rod 604, so that the watering is evenly distributed.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
