Description

Technical Field

[0001] The invention belongs to the technical field of agricultural greenhouses, and in particular relates to a spraying device for an agricultural greenhouse and a working method thereof. Background Art

[0002] With the development of agriculture, the promotion of agricultural greenhouses has become more and more widespread, and people can easily obtain off-season vegetables. Agricultural greenhouses are composed of a frame and a covering film, providing a controllable space for the growth of crops.

[0003] At present, when greenhouses are used to grow crops, spraying equipment is used more and more widely in agricultural greenhouses. The crops grown in the greenhouses are sprayed with water, nutrient solution or pesticides through the spraying equipment, which improves the convenience of people's maintenance of crops in the greenhouses.

[0004] The invention patent with publication number CN111512858A discloses an energy-saving spraying device for agricultural greenhouses and its working method. The device drives the nozzle to adjust the spraying position at multiple angles and directions through a motor, so that the device can spray water on crops in different areas of the greenhouse in a more targeted manner, saving the amount of water required for spraying crops. Although the technology can adjust the angle and direction of the nozzle, so as to spray crops in different areas in a targeted manner, and is easy to use, the nozzle in the technology is arranged around a support plate, resulting in a small range of spraying of the nozzle. It is necessary to first drive the nozzle to move in the X direction, and then drive the nozzle to move in the Y direction, so as to achieve uniform spraying of crops in the greenhouse. Such a spraying method takes a long time and reduces the efficiency of spraying crops.

[0005] Therefore, in view of the above problems, a spraying device and a working method for an agricultural greenhouse are provided, which can adjust the spacing between nozzles according to the planting range of crops in the greenhouse and evenly spray the crops by moving along the length direction of the greenhouse. Summary of the invention

[0006] The purpose of the present invention is to address the above-mentioned technical problems and to provide a spraying device and a working method for an agricultural greenhouse which can adjust the spacing between nozzles according to the planting range of crops in the greenhouse and evenly spray the crops by moving along the length direction of the greenhouse.

[0007] In view of this, the present invention provides a spraying device for an agricultural greenhouse and a working method thereof, comprising a greenhouse frame and a moving component moving on the greenhouse frame, characterized in that:

[0008] A spraying member, arranged at the lower side of the moving assembly;

[0009] An adjusting component is arranged on the moving component, and is used to adjust the height of the spraying member;

[0010] An expansion component is arranged on the adjustment component and cooperates with the spraying member. The expansion component is used to adjust the spacing of the spraying members and is suitable for spraying crops planted with different widths;

[0011] The expansion components include:

[0012] A supporting shell is arranged on the adjusting assembly;

[0013] The first ear plates are arranged on the left and right sides and the front and rear sides of the supporting shell;

[0014] A first guide rod, disposed on the first ear plate;

[0015] A connecting frame, arranged between two adjacent first guide rods;

[0016] A movable shell, having a plurality of movable shells, is slidably disposed between two first guide rods on the same side;

[0017] A connecting groove is provided on the moving shell, and a spraying member is located on the moving shell and is connected to the connecting groove;

[0018] The stretching tube has multiple sections and is arranged on the left and right sides of the supporting shell. The stretching tube is arranged between two adjacent connecting grooves and is connected to the connecting grooves.

[0019] There are two water pipes, which run through the left and right sides of the support shell and are connected to the stretching pipes arranged on the left and right sides of the support shell;

[0020] A concentrating pipe is arranged between two water delivery pipes and is connected with the water delivery pipes;

[0021] The connecting pipe is arranged on the connecting frame, and the other end of the connecting pipe is connected to the connecting groove close to the connecting frame.

[0022] In the present technical scheme, when it is necessary to use the spraying equipment of the agricultural greenhouse, people first place the moving component in the equipment on the greenhouse frame, and then adjust the moving shell to both sides along the first guide rod according to the internal width area of ​​the greenhouse and the planting range of crops in the greenhouse. The moving shell drives the stretching tube to stretch to both sides, so that the two adjacent spraying parts are separated from each other, increasing the spraying area of ​​the crops. When the spraying part moves to a width suitable for uniform spraying of the crops, people stop adjusting the spraying part, and then start the adjustment component. The adjustment component drives the supporting shell to move upward, and the supporting shell drives all the mounting parts thereon to move upward. When the spraying part moves upward and is adjusted to a suitable distance from the crops, people close the adjustment component. At this time, the external pipe is installed on the central pipe. The external pipe transports the water into the central pipe, and transports it to the transport pipe through the central pipe diversion. The water is transported from the transport pipe to the stretching pipe, flows from the stretching pipe to the connecting groove, and finally flows into the connecting pipe. The water in the connecting groove is sprayed from the spraying part to the crops in the greenhouse. Then people start the moving component, and the moving component moves linearly toward the rear or front side on the greenhouse frame. The moving component drives the equipment to move forward and backward or toward the rear side of the greenhouse, so that the spraying parts evenly spray water, pesticides or nutrient solutions on the crops in the greenhouse. At the same time, the central pipe drags the external pipe to move, so that the external pipe does not need to be dragged manually, thereby improving the efficiency of watering the crops. When the crops in the greenhouse are watered, people turn off the moving component to stop the movement of the equipment. When it is necessary to spray water, pesticides and nutrient solutions on crops in other greenhouses, people remove the equipment from the frame and place it in the greenhouse where the crops need to be watered. Finally, the position of the spraying parts can be adjusted according to the width of the greenhouse and the planting range between the crops, thereby increasing the spraying range of the crops, and facilitating the watering of water, pesticides and nutrient solutions on crops of different widths. It is easy to use, does not require manual operation, improves the efficiency of watering the crops, and saves time and effort.

[0023] In the above technical solution, further, the spraying member includes:

[0024] A water outlet pipe is arranged on the moving shell and is connected with the connecting groove;

[0025] Bellows, movable arrangement on the water outlet pipe;

[0026] The nozzle is arranged on the corrugated pipe.

[0027] In this technical solution, when working, people can rotate or pull the bellows, so that the bellows drives the sprinkler to adjust the angle and direction, which is convenient for watering crops in dead corners in the greenhouse and is easy to use.

[0028] In any of the above technical solutions, further, the mobile component includes:

[0029] There are two sliders, which are respectively arranged on both sides of the greenhouse frame;

[0030] A support rod is arranged between the two slide blocks;

[0031] A connecting block is arranged on the support rod;

[0032] Brackets, arranged on the front and rear sides of the connecting block;

[0033] A dual-axis motor is arranged on a bracket;

[0034] There are two connecting rods, which are respectively arranged on the left and right sides of the support rod;

[0035] A shaft sleeve is arranged on both sides of the front and rear of the connecting rod;

[0036] The guide wheel is arranged on the shaft sleeve and is located on the greenhouse frame;

[0037] The first rotating shaft is rotatably arranged on the guide wheel, and the output shaft of the double-axis motor passes through the shaft sleeve and is connected with the first rotating shaft.

[0038] In the present technical scheme, when working, people first place the guide wheel in the equipment on the greenhouse frame, and at the same time place the slider on the greenhouse frame. When it is necessary to spray water evenly on the crops, people start the dual-axis motor, and the output shaft of the dual-axis motor drives the first rotating shaft to rotate, and the first rotating shaft drives the guide wheel to rotate. During the rotation of the guide wheel, it moves forward and backward along the greenhouse frame, and the guide wheel drives other installation components of the equipment to move forward and backward, so that the slider moves forward and backward along the greenhouse frame. The slider can play a guiding role, making the equipment more stable during movement. At the same time, during the movement of the equipment, the sprinkler evenly irrigates the crops in the greenhouse. When the crops in the greenhouse are irrigated, people turn off the dual-axis motor. When it is necessary to irrigate the crops in other greenhouses, people remove the equipment from the greenhouse frame, so that it can automatically move forward and backward along the greenhouse frame without manual movement. It is easy to disassemble and install.

[0039] In any of the above technical solutions, further, a threaded section is provided at one end of the guide wheel, a threaded sleeve is provided on the outer diameter of the threaded section, the threaded section is threadedly connected to the threaded sleeve, and the output shaft of the dual-axis motor passes through and extends out of the sleeve and is connected to the threaded sleeve.

[0040] In the present technical scheme, after the guide wheel has been working for a long time, the friction between the guide wheel and the greenhouse frame causes the guide wheel to wear, affecting the movement of the guide wheel. Therefore, when the guide wheel needs to be replaced, people press the threaded sleeve with one hand and then rotate the guide wheel. The guide wheel drives the threaded section to rotate. During the rotation, the threaded section moves to one side and disengages from the threaded sleeve. People then remove the guide wheel and replace it with a new guide wheel, and rotate the guide wheel in the opposite direction. The guide wheel drives the threaded section to rotate in the opposite direction. During the reversal of the threaded section, it moves to the other side and locks with the threaded sleeve. In this way, the guide wheel can be disassembled and installed, which is convenient for disassembly, installation and use.

[0041] During operation, the threaded section is arranged on the side of the guide wheel, the threaded section is sleeved in the threaded sleeve and is threadedly connected to the threaded sleeve. The threaded sleeve is connected to the output shaft of the dual-axis motor, so that when the output shaft of the dual-axis motor drives the threaded sleeve to rotate, there is no force point between the threaded sleeve and the threaded section, so that the threaded sleeve drives the first rotating shaft to rotate through the threaded section, and the first rotating shaft drives the guide wheel to rotate. During the rotation of the guide wheel, the guide wheel moves forward along the greenhouse frame. When the guide wheel needs to be replaced, people need to press the threaded sleeve and then rotate the guide wheel. The guide wheel moves to one side during the rotation and drives the threaded section to move and disengage from the threaded sleeve. At this time, the guide wheel is replaced.

[0042] In any of the above technical solutions, further, the adjustment component includes:

[0043] There are two mounting brackets, which are set on the left and right sides of the support pole;

[0044] A servo motor is arranged at the bottom of the mounting frame;

[0045] The screw is arranged on the output shaft of the servo motor, and the support shell is threadedly connected to the screw;

[0046] A second guide rod is arranged at the bottom of the connecting block;

[0047] The first moving block is arranged at the rear side of the supporting shell, and the first moving block is slidably connected with the second guide rod.

[0048] In the present technical solution, when it is necessary to adjust the nozzle to a height suitable for crops, people start the servo motor, and the output shaft of the servo motor drives the screw to rotate forward and reverse, so that during the forward and reverse rotation of the screw, the support shell drives the first moving block to move upward or downward along the second guide rod, and at the same time, the support shell drives all the mounting components thereon to move upward. When the nozzle moves upward to a height suitable for crops, people turn off the servo motor to stop the screw from rotating. In this way, the height of water irrigation can be adjusted according to crops of different heights and types, which is suitable for watering crops of different heights and improves the quality of watering crops.

[0049] In any of the above technical solutions, further, a locking assembly is included, and the locking assembly includes:

[0050] There are two support rods, which are respectively arranged on the left and right sides of the bottom of the support rod;

[0051] A positioning block is arranged between the bottoms of the two support rods;

[0052] There are two installation slots, one on each side of the positioning block;

[0053] A ratchet gear is slidably disposed in the mounting groove;

[0054] There are four third guide rods, which are respectively arranged on the left and right sides and the front and rear sides of the positioning block;

[0055] A guide block is slidably arranged on the third guide rod, and two guide blocks on the same side are connected to the ratchet gear on the same side;

[0056] A handle is arranged on the outer side of the guide block;

[0057] An elastic member is arranged between the guide block and the positioning block, and provides a resetting elastic force to the ratchet gear;

[0058] A mounting sleeve is arranged on the screw rod;

[0059] A rotating rod, rotatably arranged on the mounting sleeve;

[0060] A ratchet pawl is arranged on the rotating rod, and the ratchet pawl is engaged with the ratchet gear;

[0061] There are two torsion springs, which are arranged between the ratchet pawl and the mounting sleeve and sleeved on the rotating rod.

[0062] In the technical solution, when working, after the mounting components on the support shell are adjusted to a height suitable for spraying crops, the servo motor and the screw stop working. However, when the support shell and all the components thereon are spraying water, the weight of the support shell and all the mounting components thereon, and even the weight of the water, can easily cause the screw to fail and rotate due to external forces, resulting in a change in the position of the support shell, affecting the normal operation of other mounting components on the screw. Therefore, initially, the ratchet gear is clamped with the pawl, and when the screw fails due to external forces, When rotating, the screw drives the installation sleeve to rotate slightly, the installation sleeve drives the rotating rod to rotate slightly, the rotating rod drives the pawl to rotate slightly, the pawl contacts the inner teeth of the ratchet gear during the slight rotation, the ratchet gear clamps the pawl so that the pawl cannot rotate, and the torsion spring is slightly deformed to ensure that the screw will not fail due to external force and cause rotation, so that other installation parts on the screw can work more stably. When it is necessary to adjust the position of the nozzle to align with the crop, people pull the handle to drive the guide block to move downward along the third guide rod, the elastic member is compressed, and the guide block drives the ratchet gear The wheel moves downward along the mounting groove, and when the ratchet gear moves downward until it is out of contact with the pawl, the ratchet gear will not clamp the pawl. Under the reset action of the torsion spring, the pawl drives the rotating rod to rotate in the opposite direction and reset. At this time, people start the servo motor, and the output shaft of the servo motor drives the screw rod to rotate forward and reversely. The supporting shell drives all the mounting parts thereon to move upward or downward, thereby adjusting the position of the sprinkler head to align with the crops. When the sprinkler head is adjusted to a height suitable for spraying the crops, people turn off the servo motor and release the handle. Under the reset action of the elastic member, the guide The block moves upward along the third guide rod, and the guide block drives the handle to move upward. At the same time, the guide block drives the ratchet gear to move upward to clamp the pawl, so that the pawl and the screw cannot rotate at will, so that the mounting components on the support shell can work normally, and the spraying of water on crops is more stable. Finally, the screw can be locked when it is not working, so as to avoid the screw malfunctioning due to external force and causing self-rotation, which affects the displacement of the mounting components on the support shell, causing the position of the sprinkler head spraying on the crops to change, and achieving the purpose of uneven spraying of crops.

[0063] In any of the above technical solutions, further, the elastic member is a return spring.

[0064] In the present technical solution, a return spring is used as the elastic member, which not only has a good effect, but also has the characteristics of easy installation and low price, thus saving production costs.

[0065] In any of the above technical solutions, further, an anti-slip cover is provided on the outer side of the handle.

[0066] In the present technical solution, an anti-slip sleeve is provided on the outside of the handle, which can play an anti-slip role and prevent people from slipping during work due to the smooth surface of the handle when working on it. The anti-slip sleeve can enable people to work on the handle more stably.

[0067] In any of the above technical solutions, further, a positioning component is included, and the positioning component includes:

[0068] The second ear plates are arranged on the left and right sides of the bottom of the supporting shell;

[0069] A third ear plate is arranged at the bottom of the connecting frame;

[0070] There are two fourth guide rods, which are respectively arranged between the adjacent second ear plates and the third ear plates;

[0071] The second moving blocks are consistent in number with the stretching tubes and correspond one to one, and the second moving blocks are slidably arranged on the fourth guide rod;

[0072] A supporting block, arranged at the rear side of the second moving block;

[0073] A second rotating shaft is rotatably disposed on the supporting block;

[0074] A pressing block is arranged on the second rotating shaft and covers the stretching tube, and the pressing block is in contact with the second moving block;

[0075] The torsion spring is sleeved on the second rotating shaft and arranged between the pressing block and the supporting block.

[0076] In the present technical scheme, initially, the second movable block supports the stretch tube so that the stretch tube will not sag due to the weight of the water after being filled with water. At the same time, the pressing block covers the stretch tube. When it is necessary to adjust the spacing of the nozzle according to the planting width of the crops in the greenhouse, people rotate the pressing block to drive the second rotating shaft to rotate, and the torsion spring is deformed. After the pressing block rotates ninety degrees, it will not cover the stretch tube. At this time, people pull the movable shell outward to drive the stretch tube to lengthen and increase the area sprayed on the crops. When the nozzle moves to a width suitable for uniform spraying of the crops, people stop pulling the movable shell, and then people move the second movable block along the fourth guide rod to adjust the second movable block to a position suitable for supporting the stretch tube so that the stretch tube is evenly stressed. Then people release the pressing block. Under the resetting action of the torsion spring, the pressing block drives the second rotating shaft to rotate in the opposite direction. After the pressing block reverses ninety degrees, it covers the stretch tube. In this way, the stretch tube can be supported and the stretch tube can be prevented from sagging due to uneven stress during the water transportation process.

[0077] In any of the above technical solutions, further, the following steps are included:

[0078] Step S1: According to the planting range of crops in the greenhouse, the movable shell is adjusted to both sides, and the movable shell drives the stretching tube to stretch outward, thereby expanding the distance between the nozzles, so as to facilitate uniform spraying of water on crops in greenhouses of different widths;

[0079] Step S2: The nozzle and the water outlet pipe are connected via a bellows, which can be rotated and stretched to adjust the angle or direction of the nozzle, so as to facilitate watering crops in dead corners of the greenhouse;

[0080] Step S3: Using a dual-axis motor as a driving force, the threaded sleeve is driven to rotate, the threaded sleeve drives the threaded section to rotate, the threaded section drives the first rotating shaft to rotate, and the first rotating shaft drives the guide wheel to rotate. During the rotation of the guide wheel, it moves forward and backward along the greenhouse frame, thereby driving the device to move in the front and rear directions of the greenhouse interior;

[0081] Step S4: The threaded segment is threadedly connected to the threaded sleeve. People rotate the guide wheel to drive the threaded segment to rotate. During the rotation process, the threaded segment moves to one side and separates from the threaded sleeve. At this time, the guide wheel can be replaced;

[0082] Step S5: The servo motor is used as a driving force to drive the screw to rotate, and the support shell moves upward along the second guide rod, and the support shell drives other mounting components thereon to move upward, thereby adjusting the distance between the sprinkler head and the crops, so as to facilitate watering crops at different heights;

[0083] Step S6: The ratchet gear is used to clamp the pawl so that the screw rod cannot rotate, so as to prevent the screw rod from rotating due to the influence of external force when supporting other installation components when not working, thereby affecting the normal operation of other installation components on the screw rod;

[0084] Step S7: The second moving block holds the stretch tube, thereby supporting the stretch tube. After the stretch tube is stretched, people adjust the second moving block to a suitable position so that the stretch tube can be evenly stressed.

[0085] The beneficial effects of the present invention are:

[0086] 1. According to the planting range of crops in the greenhouse, the movable shell is adjusted to both sides. The movable shell drives the stretching tube to stretch outward, thereby expanding the distance between the nozzles, making it easier to evenly spray water, pesticides, and nutrient solutions on crops in greenhouses of different widths. It is easy to use and does not require manual operation, which improves the efficiency of crop spraying and saves time and effort.

[0087] 2. The double-axis motor is used as the driving force to drive the threaded sleeve to rotate, the threaded sleeve drives the threaded section to rotate, the threaded section drives the first rotating shaft to rotate, and the first rotating shaft drives the guide wheel to rotate. During the rotation of the guide wheel, it moves forward and backward along the greenhouse frame, thereby driving the device to move in the front and back directions of the greenhouse. The slider can play a guiding role, making the device more stable during the movement, so that the crops can be sprayed evenly without manual operation;

[0088] 3. Through the threaded connection between the threaded section and the threaded sleeve, people rotate the guide wheel to drive the threaded section to rotate. During the rotation of the threaded section, it moves to one side and disengages from the threaded sleeve, so that the guide wheel can be removed. In this way, the guide wheel can be replaced, which is convenient for replacement and installation;

[0089] 4. The servo motor is used as a driving force to drive the screw to rotate, and the support shell drives other installation components on it to move upward, thereby adjusting the distance between the sprinkler head and the crops, making it easier to irrigate crops at different heights;

The mobile shell 35 drives the stretching tube 37 to stretch to both sides, so that the two adjacent spraying parts 2 are separated from each other, increasing the area sprayed on the crops. When the spraying part 2 moves to a width suitable for uniformly spraying the crops, people stop adjusting the spraying part 2 and then start the adjustment component 7.

Finally, the position of the spraying member 2 can be adjusted according to the width of the greenhouse and the planting range of the crops, thereby increasing the spraying range of the crops and facilitating the watering of crops of different widths with water, pesticides and nutrient solutions. It is easy to use, does not require manual operation, improves the efficiency of watering the crops, and saves time and effort.

[0119] Embodiment 2:

[0120] This embodiment provides a spraying device for an agricultural greenhouse and a working method thereof, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features.

[0121] like Figure 1-Figure 3 As shown, in this embodiment, the spraying member 2 is optimized to include:

[0122] The water outlet pipe 21 is disposed on the moving shell 35 and communicates with the connecting groove 36;

[0123] The bellows 22 is movably arranged on the water outlet pipe 21;

[0124] The nozzle 23 is disposed on the bellows 22 .

[0125] In this technical solution, when working, people can rotate or pull the bellows 22, so that the bellows 22 drives the nozzle 23 to adjust the angle and direction, which is convenient for watering crops in dead corners in the greenhouse and is easy to use.

[0126] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the optimized moving component 4 includes:

[0127] There are two sliders 41, which are respectively arranged on both sides of the greenhouse frame 1;

[0128] A support rod 42 is disposed between the two sliders 41;

[0129] A connecting block 43 is disposed on the support rod 42;

[0130] Brackets 44 are arranged at the front and rear sides of the connecting block 43;

[0131] A dual-axis motor 45 is disposed on the bracket 44;

[0132] There are two connecting rods 46, which are respectively arranged on the left and right sides of the support rod 42;

[0133] A shaft sleeve 47 is provided at the front and rear sides of the connecting rod 46;

[0134] The guide wheel 48 is arranged on the shaft sleeve 47 and is located on the greenhouse frame 1;

[0135] The first rotating shaft 49 is rotatably disposed on the guide wheel 48 , and the output shaft of the dual-axis motor 45 passes through the shaft sleeve 47 and is connected to the first rotating shaft 49 .

[0136] In the present technical scheme, when working, people first place the guide wheel 48 in the device on the greenhouse frame 1, and at the same time place the slider 41 on the greenhouse frame 1. When it is necessary to spray water evenly on the crops, people start the dual-axis motor 45, and the output shaft of the dual-axis motor 45 drives the first rotating shaft 49 to rotate, and the first rotating shaft 49 drives the guide wheel 48 to rotate. During the rotation of the guide wheel 48, it moves forward and backward along the greenhouse frame 1. The guide wheel 48 drives other installation components of the device to move forward and backward, so that the slider 41 moves forward and backward along the greenhouse frame 1. The slider 41 can play a guiding role, making the device more stable during the movement. At the same time, during the movement of the device, the sprinkler 23 evenly irrigates the crops in the greenhouse. When the crops in the greenhouse are irrigated, people turn off the dual-axis motor 45. When it is necessary to irrigate the crops in other greenhouses, people remove the device from the greenhouse frame 1, so that it can automatically move forward and backward along the greenhouse frame 1 without manual movement, and it is easy to disassemble and install.

[0137] like Figure 5 As shown, in this embodiment, it is optimized that a threaded section 5 is provided at one end of the guide wheel 48, a threaded sleeve 6 is provided on the outer diameter of the threaded section 5, the threaded section 5 is threadedly connected to the threaded sleeve 6, and the output shaft of the dual-axis motor 45 passes through and extends out of the sleeve 47 to be connected to the threaded sleeve 6.

[0138] In the present technical solution, after the guide wheel 48 has been working for a long time, the friction generated between the guide wheel 48 and the greenhouse frame 1 causes the guide wheel 48 to wear, affecting the movement of the guide wheel 48. Therefore, when the guide wheel 48 needs to be replaced, people press the threaded sleeve 6 with one hand and then rotate the guide wheel 48. The guide wheel 48 drives the threaded segment 5 to rotate. During the rotation, the threaded segment 5 moves to one side and disengages from the threaded sleeve 6. People then remove the guide wheel 48 and replace it with a new guide wheel 48, and rotate the guide wheel 48 in the opposite direction. The guide wheel 48 drives the threaded segment 5 to rotate in the opposite direction. During the reversal of the threaded segment 5, it moves to the other side and locks with the threaded sleeve 6. In this way, the guide wheel 48 can be disassembled and installed, which is convenient for disassembly, installation and use.

[0139] During operation, the threaded segment 5 is arranged on the side of the guide wheel 48, the threaded segment 5 is sleeved in the threaded sleeve 6, and is threadedly connected to the threaded sleeve 6, the threaded sleeve 6 is connected to the output shaft of the dual-axis motor 45, so that when the output shaft of the dual-axis motor 45 drives the threaded sleeve 6 to rotate, there is no force point between the threaded sleeve 6 and the threaded segment 5, so that the threaded sleeve 6 drives the first rotating shaft 49 to rotate through the threaded segment 5, and the first rotating shaft 49 drives the guide wheel 48 to rotate. During the rotation of the guide wheel 48, it moves forward along the greenhouse frame 1. When the guide wheel 48 needs to be replaced, people need to press the threaded sleeve 6 and then rotate the guide wheel 48. The guide wheel 48 moves to one side during the rotation and drives the threaded segment 5 to move and disengage from the threaded sleeve 6. At this time, the guide wheel 48 is replaced.

[0140] like Figure 1 , Figure 6 and Figure 7 As shown, in this embodiment, the adjustment component 7 is optimized to include:

[0141] There are two mounting brackets 71, which are arranged on the left and right sides of the support rod 42;

[0142] A servo motor 72 is disposed at the bottom of the mounting frame 71;

[0143] The screw 73 is disposed on the output shaft of the servo motor 72, and the support shell 31 is threadedly connected to the screw 73;

[0144] A second guide rod 74 is disposed at the bottom of the connecting block 43;

[0145] The first moving block 75 is disposed at the rear side of the supporting shell 31 , and the first moving block 75 is slidably connected to the second guide rod 74 .

[0146] In the present technical solution, when it is necessary to adjust the nozzle 23 to a height suitable for crops, people start the servo motor 72, and the output shaft of the servo motor 72 drives the screw 73 to rotate forward and reverse, so that during the forward and reverse rotation of the screw 73, the support shell 31 drives the first moving block 75 to move upward or downward along the second guide rod 74, and at the same time, the support shell 31 drives all the mounted components thereon to move upward. When the nozzle 23 moves upward to a height suitable for crops, people turn off the servo motor 72 to stop the screw 73 from rotating. In this way, the height of water irrigation can be adjusted according to crops of different heights and types, which is suitable for watering crops of different heights and improves the quality of watering crops.

[0147] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, the optimization further includes a locking assembly 8, and the locking assembly 8 includes:

[0148] There are two support rods 81, which are respectively arranged on the left and right sides of the bottom of the support rod 42;

[0149] A positioning block 82 is disposed between the bottoms of the two support rods 81;

[0150] There are two mounting slots 83, which are respectively provided on the left and right sides of the positioning block 82;

[0151] A ratchet gear 84 is slidably disposed in the mounting groove 83;

[0152] There are four third guide rods 85, which are respectively arranged on the left and right sides and the front and rear sides of the positioning block 82;

[0153] A guide block 86 is slidably disposed on the third guide rod 85, and two guide blocks 86 on the same side are connected to the ratchet gear 84 on the same side;

[0154] A handle 87 is provided on the outer side of the guide block 86;

[0155] An elastic member 88 is disposed between the guide block 86 and the positioning block 82, and the elastic member 88 provides a resetting elastic force to the ratchet gear 84;

[0156] A mounting sleeve 89 is disposed on the screw rod 73;

[0157] A rotating rod 810 is rotatably mounted on the mounting sleeve 89;

[0158] A ratchet pawl 811 is disposed on the rotating rod 810, and the ratchet pawl 811 is engaged with the ratchet gear 84;

[0159] There are two torsion springs 812 , which are disposed between the pawl 811 and the mounting sleeve 89 , and sleeved on the rotating rod 810 .

[0160] In the present technical solution, when working, after the mounting components on the support shell 31 are adjusted to a height suitable for spraying crops, the servo motor 72 and the screw 73 stop working. However, when the support shell 31 and all the components thereon are spraying water, the weight of the support shell 31 and all the mounting components thereon, and even the weight of the water, can easily cause the screw 73 to fail and rotate due to external forces, resulting in a change in the position of the support shell 31, affecting the normal operation of other mounting components on the screw 73. Therefore, initially, the ratchet gear 84 clamps the ratchet pawl 811. When the screw 73 fails due to external forces and rotates, the screw 73 drives the mounting sleeve 84 to rotate. 89 rotates slightly, the installation sleeve 89 drives the rotating rod 810 to rotate slightly, and the rotating rod 810 drives the pawl 811 to rotate slightly. During the slight rotation of the pawl 811, it contacts the inner teeth of the ratchet gear 84, and the ratchet gear 84 clamps the pawl 811, so that the pawl 811 cannot rotate, and the torsion spring 812 is slightly deformed to ensure that the screw rod 73 will not fail due to external force and cause self-rotation, so that other installation components on the screw rod 73 can work more stably. When it is necessary to adjust the position of the nozzle 23 to align with the crop, people pull the handle 87 to drive the guide block 86 to move downward along the third guide rod 85, the elastic member 88 is compressed, and the guide block 86 drives the ratchet gear 8 4 moves downward along the mounting groove 83. After the ratchet gear 84 moves downward until it is out of contact with the ratchet pawl 811, the ratchet gear 84 will not clamp the ratchet pawl 811. Under the reset action of the torsion spring 812, the ratchet pawl 811 drives the rotating rod 810 to rotate in the opposite direction and reset. At this time, people start the servo motor 72. The output shaft of the servo motor 72 drives the screw rod 73 to rotate forward and reversely. The supporting shell 31 drives all the mounting parts thereon to move upward or downward, thereby adjusting the position of the spray head 23 to align with the crops. When the spray head 23 is adjusted to a height suitable for spraying the crops, people turn off the servo motor 72 and release the handle 87. Under the reset action of the elastic member 88, the spray head 23 is sprayed with water. , the guide block 86 moves upward along the third guide rod 85, and the guide block 86 drives the handle 87 to move upward. At the same time, the guide block 86 drives the ratchet gear 84 to move upward to the clamping pawl 811, and then the pawl 811 and the screw 73 cannot rotate at will, so that the mounting components on the support shell 31 can work normally, and the spraying of water on crops is more stable. Finally, the screw 73 can be locked when it is not working, so as to avoid the screw 73 from malfunctioning due to external force and causing self-rotation, causing displacement of the mounting components on the support shell 31, causing the spraying position of the spray head 23 on the crops to change, and achieving the purpose of uneven spraying of crops.

[0161] like Figure 6-Figure 8 As shown, in this embodiment, it is optimized that the elastic member 88 is a return spring.

[0162] In the present technical solution, a return spring is used as the elastic member 88, which not only has a good effect, but also has the characteristics of easy installation and low price, thus saving production costs.

[0163] like Figure 7 and Figure 8 As shown, in this embodiment, the handle 87 is optimized and an anti-slip sleeve is provided on the outside.

[0164] In the present technical solution, an anti-slip sleeve is provided on the outside of the handle 87. The anti-slip sleeve can play an anti-slip role to prevent people from slipping during the work on the handle 87 due to its smooth surface. The anti-slip sleeve can enable people to work on the handle 87 more stably.

[0165] like Figure 1 and Figure 6 As shown, in this embodiment, the optimization further includes a positioning component 9, and the positioning component 9 includes:

[0166] The second ear plates 91 are arranged on the left and right sides of the bottom of the supporting shell 31;

[0167] A third ear plate 92 is disposed at the bottom of the connecting frame 34;

[0168] There are two fourth guide rods 93, which are respectively disposed between the adjacent second ear plates 91 and the third ear plates 92;

[0169] The second moving blocks 94 are the same in number as the stretching tubes 37 and correspond one to one. The second moving blocks 94 are slidably disposed on the fourth guide rod 93;

[0170] A support block 96 is disposed at the rear side of the second moving block 94;

[0171] A second rotating shaft 97 is rotatably disposed on the supporting block 96;

[0172] A pressing block 98 is disposed on the second rotating shaft 97 and covers the stretching tube 37. The pressing block 98 is in contact with the second moving block 94.

[0173] The torsion spring 99 is sleeved on the second rotating shaft 97 and disposed between the pressing block 98 and the supporting block 96 .

[0174] In the present technical solution, initially, the second moving block 94 supports the stretch tube 37 so that the stretch tube 37 will not sag due to the weight of the water after being filled with water. At the same time, the pressing block 98 covers the stretch tube 37. When it is necessary to adjust the spacing of the nozzles according to the planting width of the crops in the greenhouse, people rotate the pressing block 98 to drive the second rotating shaft 97 to rotate, and the torsion spring 99 is deformed. After the pressing block 98 rotates ninety degrees, it will not cover the stretch tube 37. At this time, people pull the moving shell 35 outward to drive the stretch tube 37 to lengthen, thereby increasing the area sprayed on the crops. When the nozzle 23 moves to a suitable position for the crops, When the width of the crop is evenly sprayed, people stop pulling the movable shell 35, and then people move the second movable block 94 along the fourth guide rod 93, and adjust the second movable block 94 to a position suitable for supporting the stretch tube 37, so that the stretch tube 37 is evenly stressed, and then people release the pressing block 98. Under the reset action of the torsion spring 99, the pressing block 98 drives the second rotating shaft 97 to rotate in the opposite direction. The pressing block 98 is reversed by ninety degrees and then covers the stretch tube 37. In this way, the stretch tube 37 can be supported, and the stretch tube 37 can be prevented from sagging due to uneven stress during the water transportation process.

[0175] like Figure 1-Figure 8 As shown, in this embodiment, the optimization includes the following steps:

[0176] Step S1: According to the planting range of crops in the greenhouse, the movable shell 35 is adjusted to both sides, and the movable shell 35 drives the stretching tube 37 to stretch outward, thereby expanding the distance between the spray heads 23, so as to facilitate uniform spraying of water on crops in greenhouses of different widths;

[0177] Step S2: The nozzle 23 is connected to the water outlet pipe 21 via a bellows 22, and the bellows 22 can be rotated and stretched, so as to adjust the angle or direction of the nozzle 23, so as to facilitate watering the crops in the dead corners of the greenhouse;

[0178] Step S3: The double-axis motor 45 is used as a driving force to drive the threaded sleeve 6 to rotate, the threaded sleeve 6 drives the threaded section 5 to rotate, the threaded section 5 drives the first rotating shaft 49 to rotate, and the first rotating shaft 49 drives the guide wheel 48 to rotate. During the rotation process, the guide wheel 48 moves forward and backward along the greenhouse frame 1, thereby driving the device to move in the front and rear directions of the greenhouse interior;

[0179] Step S4: The threaded segment 5 is threadedly connected to the threaded sleeve 6. The guide wheel 48 is rotated to drive the threaded segment 5 to rotate. During the rotation process, the threaded segment 5 moves to one side and is separated from the threaded sleeve 6. At this time, the guide wheel 48 can be replaced.

[0180] Step S5: The servo motor 72 is used as a driving force to drive the screw rod 73 to rotate, and the support shell 31 moves upward along the second guide rod 74. The support shell 31 drives other mounting components thereon to move upward, thereby adjusting the distance between the sprinkler head 23 and the crops, so as to facilitate watering crops at different heights.

[0181] Step S6: The ratchet gear 84 clamps the pawl 811 to prevent the screw rod 73 from rotating, so as to prevent the screw rod 73 from rotating due to the external force caused by supporting other installation components when not working, thereby affecting the normal operation of other installation components on the screw rod 73;

[0182] Step S7: The second moving block 94 holds the stretch tube 37, thereby supporting the stretch tube 37. After the stretch tube 37 is stretched, people adjust the second moving block 94 to move to a suitable position so that the stretch tube 37 can be evenly stressed.
