Description

Technical Field

[0001] The present invention relates to the technical field of greenhouse planting, and in particular to a fully automatic mist spraying device for a solar greenhouse. Background Art

[0002] The track sprinkler is a highly efficient, automated fertilizing, irrigation and pesticide spraying equipment specially designed for the narrow and long space of a solar greenhouse. It achieves precise movement and uniform spraying through a track system. It is suitable for high-density planting environments such as vegetables and flowers. It has the advantages of high efficiency, pesticide and water saving, safety, environmental protection, and strong adaptability. Through regular and quantitative reasonable fertilization and pesticide spraying, it can maintain the healthy growth of greenhouse crops and achieve efficient planting.

[0003] The common greenhouse track spraying equipment on the market usually uses a motor wheel to move along the bottom of the guide rail during actual operation, and the motor wheel is squeezed and locked by an electronically controlled brake. However, this braking method is too simple. When the liquid in the solution tank is full, the weight and inertia of the equipment are large. The mobile platform cannot be effectively braked during the reciprocating movement of fertilizing and spraying. As a result, the platform will slide a short distance along the bottom of the guide rail after braking, affecting the spraying range. In addition, the traditional track spraying equipment has a single spraying range and angle of the solution, and cannot adjust the spraying angle and range according to different greenhouse crops, which results in shortcomings in use. Summary of the Invention

[0004] The present invention discloses a fully automatic mist spraying equipment for a solar greenhouse, which aims to solve the technical problems of the existing greenhouse guide rail spraying equipment during actual operation. On the one hand, the braking method of the equipment is too single, resulting in the mobile platform being unable to effectively brake in the first time; on the other hand, the traditional track spraying equipment has a fixed spray angle for the solution, and cannot adjust the angle of the pipe spraying solution according to different greenhouse crops, thus resulting in the existence of technical problems of using shortcomings.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A fully automatic mist spraying device for a solar greenhouse comprises a guide rail, a movable platform slidably connected to the bottom of the guide rail via a suspension cable, and motor wheels rotatably mounted at both ends of the movable platform, the motor wheels being in contact with the bottom of the guide rail, a locking mechanism for braking being provided at the top of the movable platform, the locking mechanism comprising a double-headed hydraulic push rod fixedly mounted on the top of the movable platform, a brake plate being mounted on each output end of the double-headed hydraulic push rod;

[0007] A liquid guide mechanism for storing the solution is provided at the bottom of the movable platform. The liquid guide mechanism includes a frame plate suspended from the bottom of the movable platform by an iron chain. A pump is mounted on one side of the top of the frame plate. The output end of the pump is connected to a water outlet pipe. The end of the water outlet pipe extends through the bottom of the frame plate.

[0008] The bottom of the liquid guide mechanism is provided with a spray mechanism for spraying the solution, the spray mechanism includes a fixed plate fixedly mounted on the bottom of the frame plate, a transfer pipe is rotatably mounted on the bottom of the fixed plate, the water outlet pipe and the transfer pipe are connected in a through-connected manner, and a five-way pipe is connected in a through-connected manner at the bottom of the transfer pipe;

[0009] A regulating mechanism is provided on the outside of the spray mechanism;

[0010] The motor wheel drives the movable platform, the liquid guiding mechanism and the spraying mechanism to move and spray liquid along the bottom of the guide rail. The rotation speed of the spraying mechanism is controlled to drive the regulating mechanism to operate, thereby changing the spraying range of the spraying mechanism. The movable platform is braked by controlling the locking mechanism.

[0011] By providing a locking mechanism on the top of the movable platform, the motor wheel and the sling are locked synchronously by the operation of the locking mechanism, thereby greatly improving the braking capacity of the traditional spraying equipment. At the same time, an additional spraying mechanism is provided at the bottom of the liquid guide mechanism, and the water pressure is used to drive the rotation speed of the spraying mechanism to change, thereby changing the working form of the spraying mechanism. In conjunction with the synchronous operation of the control mechanism, the equipment can have a variety of angles and forms of spraying solutions, thereby adaptively spraying crops at different heights, greatly improving the functionality and work efficiency of traditional guide sprayers.

[0012] In a preferred embodiment, the locking mechanism further includes a first extrusion portion provided at one end of the brake plate, and a second extrusion portion provided at the other end of the brake plate, wherein the first extrusion portion is in extrusion contact with the outer side of the motor wheel, and the second extrusion portion is in extrusion contact with the bottom of the suspension cable.

[0013] By providing two brake plate structures driven by a double-headed hydraulic push rod, the brake plates are used to move horizontally outward, thereby driving the first and second extrusion parts located at the ends of the brake plates to move synchronously, and at the same time, the suspension rope and the motor pulley are braked synchronously, thereby greatly improving the braking capacity of traditional equipment.

[0014] In a preferred solution, the liquid guiding mechanism further comprises a water tank fixedly mounted on the top of the frame, and the input end of the pump is connected to the interior of the water tank via a water inlet pipe.

[0015] By suspending a water tank structure with assembled solution at the bottom of the movable platform, a pump is used to discharge the solution in the water tank in conjunction with the horizontal movement of the movable platform, thereby spraying the crops inside the entire solar greenhouse and ensuring the complete operation of this equipment.

[0016] In a preferred solution, the spray mechanism further comprises a plurality of pipe fittings rotatably mounted on the ends of the five-way pipe, and a soft rubber tube is connected to the top of each pipe fitting through the interior of the five-way pipe.

[0017] By providing a transfer tube structure rotatably installed under the fixed plate at the bottom of the frame, a pump is used to drive the solution inside the water tank into the interior of the transfer tube, and the water pressure is used to drive the transfer tube and the five-way pipe and pipe fittings below the transfer tube to rotate synchronously. Under normal circumstances, the pipe fittings and the nozzle are perpendicular to the ground, and the solution is sprayed on the crops in the solar greenhouse. When the water pressure flowing through the inside of the transfer tube increases, the rotation speed of the transfer tube is synchronously increased, so that inertia is used to drive the pipe fittings to rotate around the five-way pipe, changing the direction of the pipe fittings and the nozzle, so that the device can freely adjust the spray angle of the solution, thereby improving the functionality of traditional guide rail sprayers.

[0018] In a preferred embodiment, the regulating mechanism includes a threaded groove opened on the outside of each of the pipe fittings, the outer side of the threaded groove is threadedly connected to a nut, the bottom of the nut is rotatably installed with an adapter ring, the bottom of the adapter ring is connected to a sleeve through a spring, the spring is sleeved on the outside of the pipe fitting, the sleeve is slidably sleeved on the outside of the pipe fitting through a sliding groove, and a number of liquid separation holes are evenly opened on the outside of the sleeve and the pipe fitting, and the several liquid separation holes can overlap or be staggered with each other.

[0019] A nut is installed on the outside of the pipe using a thread, and the nut is connected to the sleeve through an adapter ring and a spring. Under normal circumstances, as the pipe rotates at high speed, the sleeve can rely on its own inertia to overcome the tension of the spring and slide along the outside of the pipe, causing the sleeve and the liquid separation hole on the outside of the pipe to be aligned, thereby changing the liquid discharge angle and range of the pipe. The user can also actively rotate the nut to change the distribution position of the sleeve under normal circumstances, thereby actively adjusting the liquid discharge angle and range of the pipe, thereby improving the functionality of this device.

[0020] From the above, it can be seen that the fully automatic mist spraying equipment for a solar greenhouse provided by the present invention has the following technical effects.

[0021] First, two brake plate structures driven by double-headed hydraulic push rods are provided on the top of the movable platform. The brake plates are used to move horizontally outward, thereby driving the first and second extrusion parts located at the ends of the brake plates to move synchronously. At the same time, the suspension rope and the motor wheel that drives the entire equipment to move are synchronously braked, and the suspension rope is tilted by the squeezing method, causing the brake pads and the guide rails to be squeezed to form a single brake, the motor wheel and the guide rails to be squeezed to form a double brake, and the motor wheel is directly squeezed by the brake plates to form a triple brake, thereby greatly improving the braking capacity of the traditional track sprinkler equipment and improving the stability of the equipment during operation.

[0022] Secondly, a transfer pipe structure is provided at the bottom of the frame plate and is rotatably installed under the fixed plate. A pump is used to drive the solution inside the water tank into the transfer pipe, and the water pressure is used to drive the transfer pipe and the five-way pipe and pipe fittings below the transfer pipe to rotate synchronously. Under normal circumstances, the pipe fittings and the nozzles are perpendicular to the ground, and the solution is sprayed on the crops in the solar greenhouse. When the water pressure flowing through the inside of the transfer pipe increases, the rotation speed of the transfer pipe increases synchronously, and inertia is used to drive the pipe fittings to rotate around the five-way pipe, thereby changing the direction of the pipe fitting nozzle, so that the equipment can freely adjust the spray angle of the solution according to the height of the crops planted in the greenhouse and the needs of the user, thereby greatly improving the functionality of the traditional guide rail sprayer.

[0023] Third: by using an additional thread to install a nut on the outside of the pipe, the nut is connected to the sleeve through an adapter ring and a spring. As the pipe rotates at high speed, the sleeve can rely on its own inertia to overcome the tension of the spring and slide along the outside of the pipe, causing the sleeve and several groups of liquid holes on the outside of the pipe that are normally displaced to be aligned, thereby changing the liquid outlet angle and range of the nozzle. The user can also actively rotate the nut to change the distribution position of the sleeve under normal conditions, directly aligning the sleeve and several groups of liquid holes on the outside of the pipe that are normally displaced to be aligned, thereby actively adjusting the liquid outlet angle and range of the nozzle, and further improving the functionality of the device.

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] The invention discloses a fully automatic mist spraying device for a solar greenhouse, which is mainly used for spraying, watering, fertilizing and spraying pesticides in a solar greenhouse.

[0041] Reference Figures 1 to 14 A fully automatic mist spraying device for a solar greenhouse comprises a guide rail 1, a movable platform 3 slidably connected to the bottom of the guide rail 1 via a suspension cable 2, and motor wheels 4 rotatably mounted at both ends of the movable platform 3. The motor wheels 4 are pressed and contacted with the bottom of the guide rail 1. A locking mechanism 5 for braking is provided on the top of the movable platform 3. The locking mechanism 5 comprises a double-headed hydraulic push rod 501 fixedly mounted on the top of the movable platform 3. A brake plate 502 is mounted on both output ends of the double-headed hydraulic push rod 501.

[0042] A liquid guide mechanism 6 for storing the solution is provided at the bottom of the movable platform 3. The liquid guide mechanism 6 includes a frame 601 suspended from the bottom of the movable platform 3 by an iron chain. A pump 603 is mounted on one side of the top of the frame 601. The output end of the pump 603 is connected to a water outlet pipe 605. The end of the water outlet pipe 605 extends through the bottom of the frame 601.

[0043] A spray mechanism 7 for spraying the solution is provided at the bottom of the liquid guide mechanism 6. The spray mechanism 7 includes a fixed plate 701 fixedly mounted on the bottom of the frame plate 601. A transfer pipe 702 is rotatably mounted on the bottom of the fixed plate 701. The water outlet pipe 605 is connected to the transfer pipe 702 through-connected. A five-way pipe 703 is connected through-connected to the bottom of the transfer pipe 702.

[0044] A regulating mechanism 8 is provided on the outside of the spray mechanism 7;

[0045] The motor wheel 4 drives the movable platform 3, the liquid guiding mechanism 6 and the spraying mechanism 7 to move along the bottom of the guide rail 1 while spraying liquid. The speed of the spraying mechanism 7 is controlled to drive the regulating mechanism 8 to operate, thereby changing the spraying range of the spraying mechanism 7. The movable platform 3 is braked by controlling the locking mechanism 5.

[0046] In this embodiment: the operator adds solution to the interior of the liquid guiding mechanism 6, and at the same time uses an iron chain and a hook to hang the liquid guiding mechanism 6 on the bottom of the movable platform 3, and starts the entire device at the same time. The motor wheel 4 starts to rotate, driving the entire device to move slowly along the bottom of the guide rail 1. At the same time, the liquid guiding mechanism 6 runs synchronously, guiding the solution into the interior of the spraying mechanism 7, and the spraying mechanism 7 rotates and sprays the solution into atomization, and evenly sprays it on the crops inside the solar greenhouse; when the movable platform 3 needs to brake, the locking mechanism 5 is operated at this time, and the locking mechanism 5 will squeeze and contact the side of the motor wheel 4 and the suspension cable 2, thereby braking the entire device; when the spraying mechanism 7 is spraying and irrigating the crops inside the solar greenhouse, the operator remotely controls the liquid guiding mechanism 6 according to demand to increase the liquid flow rate into the spraying mechanism 7, causing the rotation speed of the spraying mechanism 7 to increase, and at the same time drives the control mechanism 8 to run synchronously to change the spray angle and range of the spraying mechanism 7.

[0047] Reference Figures 1 to 4 In a preferred embodiment, the locking mechanism 5 also includes a first-class extrusion portion 503 provided at one end of the brake plate 502, and a second-class extrusion portion 504 provided at the other end of the brake plate 502. The first-class extrusion portion 503 is in extrusion contact with the outside of the motor wheel 4, and the second-class extrusion portion 504 is in extrusion contact with the bottom of the suspension cable 2, and pulleys 201 are rotatably installed at both ends of the top of each suspension cable 2, and the pulleys 201 are slidably distributed inside the guide rail 1, and a brake pad 202 is provided at the top of the suspension cable 2 and below the pulley 201.

[0048] When the moving platform 3 needs to brake, the double-headed hydraulic push rod 501 is in operation. The output end of the double-headed hydraulic push rod 501 extends outward and pushes the brake plate 502, causing the two brake plates 502 to move toward the motor wheel 4 until the first type of extrusion portion 503 presses and contacts the outer side of the motor wheel 4, thereby braking the motor wheel 4. At the same time, the second type of extrusion portion 504 presses and contacts the bottom of the suspension cable 2. The compressed suspension cable 2 tilts, causing the brake plate 202 to contact the bottom of the guide rail 1, thereby applying a double brake to the entire device.

[0049] Specifically, a flexible steel cable 505 is connected between the bottom of the suspension cable 2 and the moving platform 3, and the second type of extrusion part 504 squeezes and contacts the side of the flexible steel cable 505, causing the flexible steel cable 505 and the suspension cable 2 to tilt; and a central groove 506 is opened through the top of the brake plate 502, and the flexible steel cable 505 is distributed inside the central groove 506. When the brake plate 502 moves horizontally, the flexible steel cable 505 will move synchronously along the inside of the central groove 506.

[0050] Furthermore, it is supplemented that: connecting frames 10 are rotatably provided on both sides of the movable platform 3, the upper end of the connecting frame 10 is rotatably connected to the motor wheel 4, and an elastic pushing member 9 is rotatably installed between the lower end of the connecting frame 10 and the movable platform 3. The elastic pushing member 9 will squeeze and push the lower end of the connecting frame 10, so that the connecting frame 10 and the motor wheel 4 rotate upward around the hinge point, causing the motor wheel 4 to be in close contact with the bottom of the guide rail 1.

[0051] Reference Figures 1 to 3 、 Figures 5 and 6 In a preferred embodiment, the liquid guiding mechanism 6 further includes a water tank 602 fixedly mounted on the top of the frame 601 , and the input end of the pump 603 is connected to the interior of the water tank 602 through a water inlet pipe 604 .

[0052] The operator adds solution to the inside of the water tank 602, and uses iron chains and hooks to hang the frame 601 on the bottom of the movable platform 3. At the same time, the entire device is started, and the motor wheel 4 starts to rotate, driving the entire device to move slowly along the bottom of the guide rail 1. At the same time, the pump 603 runs synchronously, and the solution is pumped out from the inside of the water tank 602 through the water inlet pipe 604, and introduced into the inside of the spray mechanism 7 through the water outlet pipe 605. The solution is atomized and sprayed out while the spray mechanism 7 rotates.

[0053] Reference Figures 1 to 2 、 Figures 5 to 9 In a preferred embodiment, the spraying mechanism 7 also includes a plurality of pipe fittings 704 rotatably installed at the end of the five-way pipe 703, and the top of each pipe fitting 704 is connected to the interior of the five-way pipe 703 with a soft rubber tube 705, and a nozzle 708 is provided at the lower end of the pipe fitting 704.

[0054] The pump 603 operates synchronously, pumping the solution out of the water tank 602 through the water inlet pipe 604 and introducing it into the inside of the transfer pipe 702 through the water outlet pipe 605, causing the transfer pipe 702 to drive the five-way pipe 703 and the pipe 704 to rotate slowly. At this time, the pipe 704 is perpendicular to the ground. At the same time, the solution inside the transfer pipe 702 will be introduced into the inside of the pipe 704 through the five-way pipe 703 and the soft rubber tube 705 and sprayed out from the nozzle 708. When the spraying mechanism 7 sprays the crops inside the solar greenhouse, the operator According to demand, the pump 603 is remotely controlled to increase the output power, thereby increasing the liquid flow rate to the inside of the transfer tube 702 through the outlet pipe 605, causing the rotation speed of the transfer tube 702 to increase, thereby driving the pipe 704 to rotate at high speed. While the pipe 704 rotates, it will be affected by centrifugal force and gradually tilt upward around the upper end of the five-way pipe 703, thereby changing the liquid outlet angle of the nozzle 708; wherein, a counterweight 707 is fixedly installed at the bottom of each pipe 704, which is used to increase the inertia of the pipe 704 during its revolution.

[0055] Furthermore, it is supplemented that a spiral component 706 is fixedly installed inside the transfer tube 702. The solution entering the transfer tube 702 will impact the top of the spiral component 706, causing the spiral component 706 to drive the transfer tube 702 to rotate.

[0056] Reference Figures 7 to 9 In a preferred embodiment, the regulating mechanism 8 includes a threaded groove 801 opened on the outside of each pipe fitting 704, and the outer side of the threaded groove 801 is threadedly connected to a nut 802, and the bottom of the nut 802 is rotatably installed with an adapter ring 803, and the bottom of the adapter ring 803 is connected to a sleeve 805 through a spring 804, and the spring 804 is sleeved on the outside of the pipe fitting 704, and the sleeve 805 is slidably sleeved on the outside of the pipe fitting 704 through a sliding groove 807. A number of liquid separation holes 806 are evenly opened on the outside of the sleeve 805 and the pipe fitting 704, and the several liquid separation holes 806 can overlap or be staggered with each other.

[0057] When the pipe 704 rotates at high speed and is gradually tilted upward around the upper end rotation axis of the five-way pipe 703 by centrifugal force, the sleeve 805 located on the outside of the pipe 704 will be subjected to centrifugal force, overcome the pulling force of the spring 804 and slide along the outside of the sleeve 805, causing the liquid separation hole 806 located on the outside of the sleeve 805 and the liquid separation hole 806 located on the outside of the pipe 704 to align and overlap, thereby changing the flow path of the solution inside the pipe 704 and increasing the liquid discharge range of the solution; and under normal circumstances, the user can manually rotate the nut 802, causing the nut 802 to move along the inside of the thread groove 801, and drive the adapter ring 803, spring 804 and sleeve 805 to move synchronously, causing the liquid separation hole 806 located on the outside of the sleeve 805 and the liquid separation hole 806 located on the outside of the pipe 704 to align, thereby manually changing the flow path of the solution inside the pipe 704.

[0058] Working principle: When in use, the operator manually adds solution to the inside of the water tank 602, and uses the iron chain and hook to hang the frame 601 on the bottom of the mobile platform 3, and starts the whole device at the same time. The motor wheel 4 starts to rotate, driving the whole device to move slowly along the bottom of the guide rail 1. At the same time, the pump 603 runs synchronously, pumping the solution from the inside of the water tank 602 through the water inlet pipe 604 and introducing it into the inside of the transfer pipe 702 through the water outlet pipe 605. The solution will impact the spiral part 706 to generate a rotational driving force, causing the transfer pipe 702 to be affected by the spiral part 706. 6 is driven, thereby driving the five-way pipe 703 and the pipe 704 to rotate slowly. At this time, the pipe 704 and the nozzle 708 are perpendicular to the ground. At the same time, the solution inside the transfer pipe 702 is introduced into the interior of the pipe 704 through the five-way pipe 703 and the soft rubber tube 705 and sprayed out. When the spraying mechanism 7 sprays the crops inside the solar greenhouse, the operator remotely controls the pump 603 to increase the output power according to demand, thereby increasing the liquid flow rate to the inside of the transfer pipe 702 through the outlet pipe 605, causing the rotation speed of the transfer pipe 702 to increase, thereby driving the The movable pipe 704 rotates at a high speed. As the pipe 704 rotates, it is gradually tilted upward around the upper end of the rotating shaft of the five-way pipe 703 by the centrifugal force, thereby changing the angle of the liquid discharge from the nozzle 708. As the pipe 704 tilts, the sleeve 805 located on the outside of the pipe 704 is affected by the centrifugal force, overcomes the tension of the spring 804 and slides along the outside of the sleeve 805, causing the liquid separation hole 806 located on the outside of the sleeve 805 to align with the liquid separation hole 806 located on the outside of the pipe 704, thereby changing the flow path of the solution inside the pipe 704. The liquid discharge range of the solution is increased. Finally, when the movable platform 3 needs to brake, the double-headed hydraulic push rod 501 is in operation. The output end of the double-headed hydraulic push rod 501 extends outward and pushes the brake plate 502, causing the two brake plates 502 to move toward the motor wheel 4 until the first type of extrusion portion 503 presses and contacts the outer side of the motor wheel 4, and the second type of extrusion portion 504 presses and contacts the flexible steel cable 505 at the bottom of the suspension cable 2, causing the flexible steel cable 505 and the suspension cable 2 to tilt, causing the brake plate 202 to press against the bottom of the guide rail 1, thereby forming multiple brakes.

[0059] In summary, the liquid discharge modes of the pipe 704 are classified into the following types:

[0060] The first is that the nut 802 is at the upper limit position, the spring 804 is in a relaxed state, and the liquid separation hole 806 on the outside of the sleeve 805 is misaligned with the liquid separation hole 806 on the outside of the pipe 704. At this time, the solution is sprayed downward only from the nozzle 708. This state can be used for spraying short crops, such as Figure 10 As shown;

[0061] In the second method, the flow rate of the solution increases, the tube 704 rotates and tilts, and the centrifugal force of the rotation causes the sleeve 805 to overcome the tension of the spring 804 and slide along the outside of the sleeve 805, so that the separation hole 806 on the outside of the sleeve 805 and the separation hole 806 on the outside of the tube 704 are aligned. At this time, the solution can be sprayed from both the nozzle 708 and the separation hole 806. In this state, the diffusion range of the solution can be increased. Figure 12 As shown;

[0062] In addition, the nozzle 708 can be sealed with a stopcock so that the pipe 704 is located below the leaf surface of tall crops. In this state, only the liquid separation hole 806 sprays liquid outward, which can be used to spray tall crops and is beneficial for spraying the back of the leaves of tall crops. Figure 13 As shown;

[0063] The third method is that the user can manually rotate the nut 802, causing the nut 802 to move downward along the thread groove 801 to the extreme position, and drive the adapter ring 803, the spring 804 and the sleeve 805 to move synchronously, so that the liquid separation hole 806 located on the outside of the sleeve 805 is aligned with the liquid separation hole 806 located on the outside of the pipe 704, thereby manually changing the flow path of the solution inside the pipe 704. In this state, no matter whether the flow rate of the solution is large or small, no matter whether the pipe 704 rotates, the solution can be sprayed from both the nozzle 708 and the liquid separation hole 806. In this state, the spraying range of short crops can be increased, such as Figure 11 shown.

[0064] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
