[0013] Compared with the prior art, the present invention can achieve the following beneficial effects: 1.

The operator observes the vertical distance between the spray head and the planted crops to determine that the distance is appropriate, turns off the power device, turns on the water pump, pumps the solution to be sprayed into the long water pipe, and then sprays the crops through the spray head on the long water pipe. The movement of the slider drives the movement of the entire moving mechanism and the solution preparation mechanism to complete the spraying of the crops planted in the entire greenhouse. Full coverage spraying adjusts the distance between the spray head and the crops by moving the mobile device up and down. If the spray head is too high and far away from the crops, the spray solution may evaporate in mid-air before it falls on the crops. If the spray head is too close to the crops, the spray solution may come into contact with the crops as soon as it falls. The impact force may damage the leaves of the crops or wash away the surface soil of the crops. By properly adjusting the distance between the spray head and the crops, the above situation can be avoided and the spraying quality can be improved.

[0014] 2. This type of spraying device in the shed moves back and forth continuously through the power device, driving the rotating device to rotate clockwise and counterclockwise continuously, thereby driving the moving threaded rod meshing with the rotating device to move back and forth up and down. The up and down reciprocating motion of the moving threaded rod drives the up and down reciprocating motion of the spraying mechanism, ensuring that when spraying the crops, reciprocating spraying can be performed from top to bottom and then from bottom to top. Compared with the traditional single-direction spraying method, this type of reciprocating spraying ensures that the back of the leaves of the crops can also be sprayed, avoiding the situation where there are pests and diseases that need to be disinfected on the back of the crops but are not sprayed with pesticides, and ensuring that the spraying solution can fully cover the crops.

[0015] 3. This type of indoor spraying device is fixedly connected to the bevel gear A through a connecting rod. When the connecting rod rotates, the bevel gear A is driven to rotate. The rotation of the bevel gear A drives the bevel gears C and the bevel gear B meshing therewith to rotate, thereby driving the second stirring rod and the first stirring rod to rotate. The rotation of the second stirring rod and the first stirring rod is used to continuously stir the prepared solution, and this process is always accompanied by the rotation of the connecting rod, that is, the entire device can realize continuous stirring of the prepared solution during the spraying process, thereby ensuring sufficient mixing of the solution and uniformity of the density of the solution sprayed on the crops, thereby improving the planting efficiency and quality.

[0016] 4. This type of greenhouse spraying device, by sleeved the slider on the guide bar, the slider is fixedly connected to the moving mechanism. When the slider slides on the guide bar, it drives the moving mechanism to slide. The usable area of ​​the greenhouse is usually large. By matching the length of the long water pipe with the moving distance of the slider, the crops planted in the entire greenhouse can be fully sprayed, thereby improving the spraying efficiency and greatly reducing the time required for spraying.

[0017] 5. This type of indoor spraying device connects the connecting rod to the bevel gear A, and meshes the upper and lower parts of the bevel gear A to connect the bevel gear C and the bevel gear B, so that the connecting rod drives the rotation of the bevel gear A while rotating, and then utilizes the rotation of the bevel gear A to transmit it to the bevel gear C and the bevel gear B through meshing, and finally utilizes the second stirring rod to be sleeved in the first stirring rod, so that the first stirring rod and the second stirring rod can rotate in different directions, so that the solution is mixed more evenly, and can be mixed while spraying, thereby improving the density uniformity of the solute distribution in the entire spraying solution.

[0030] Working principle: In the first step, the operator can first determine the number of spray heads 44 according to the appropriate irrigation amount for the crop variety and the planting density of the crop. After determining the number of spray heads 44, they are installed on the long water pipe 43 at equal intervals. Then, the spraying mode is selected according to the spraying requirements, and the solution to be sprayed is prepared and loaded into the solution storage barrel 31.

[0031] In the second step, the lifting and lowering of the mobile mechanism 2 is adjusted according to the height of the planted crops, the motor 234 is turned on, the motor 234 starts to work, the motor 234 is fixedly connected to the power threaded rod 233, the power threaded rod 233 is sleeved on the first fixed column 231 and the second fixed column 232, and the power threaded rod 233 starts to move forward or backward on the path formed by the first fixed column 231 and the second fixed column 232 under the power supply of the motor 234. Figure 8As shown, a second thread 2332 is provided on the power threaded rod 233, and the second thread 2332 is meshed with the second rotating gear 225. When the second thread 2332 moves, it drives the second rotating gear 225 meshed with the second thread 2332 to rotate. The second rotating gear 225 is connected to the connecting rod 223, and one end of the connecting rod 223 is fixedly connected to the first rotating gear 224. When the second rotating gear 225 rotates, it drives the connecting rod 223 connected thereto to rotate. The rotation of the connecting rod 223 drives the rotation of the first rotating gear 224, that is, the second rotating gear 225 and the first rotating gear 224 rotate synchronously. The first rotating gear 224 is meshed with the first thread 2142 provided on the moving threaded rod 214. When the first rotating gear 224 rotates, the first thread 2142 meshed with the first rotating gear 224 is driven to move up and down, as shown in FIG. Figure 6 shown.

[0032] In the third step, the up and down movement of the movable threaded rod 214 in the second step drives the up and down movement of the connecting square plate 41 fixedly connected to the top of the movable threaded rod 214. The connecting square plate 41 is fixedly connected to the water pump 42, and the water pump 42 is fixedly connected to the long water pipe 43, thereby transmitting the up and down movement of the connecting square plate 41 to the long water pipe 43. The long water pipe 43 can complete the spraying behavior by installing the spray head 44 in the first step. At this time, the operator only needs to observe the vertical distance between the spray head 44 and the planted crops. After determining that the distance is appropriate, turn off the power device 23 and turn on the water pump 42. The water pump 42 starts to pump the solution and pumps the solution to be sprayed into the long water pipe 43, and then sprays the crops through the spray head 44 on the long water pipe 43. When the sprayed solution is pure water, that is, the crops are sprayed only for irrigation, and there is no need to stir and mix the solution, the operator can open the slider 1 after adjusting the spraying height. 2, the slider 12 will move on the guide bar 11 after the motor is turned on, and the first receiving platform 211 is fixedly connected to the slider 12. The movement of the slider 12 drives the movement of the entire moving mechanism 2 and the solution preparation mechanism 3, that is, when the slider 12 is started, the full coverage spraying of the crops planted in the entire greenhouse is completed, and the interval distance between the spray head 44 and the planted crops is adjusted by the up and down movement of the moving device 21. If the spray head 44 is too high and far away from the planted crops, the spraying solution may evaporate in mid-air before it falls on the planted crops. If the spray head 44 is too close to the planted crops, the spraying solution may contact the planted crops as soon as it falls, and the impact force generated may cause damage to the leaves of the crops or wash away the surface soil of the crops. By appropriately adjusting the distance between the spray head 44 and the planted crops, the above situation can be avoided and the spraying quality can be improved.

[0033] In the fourth step, when the sprayed solution is a specially adjusted pesticide or other nutrient solution, it is necessary to spray the entire plant of the planted crop. At this time, the operator does not need to turn off the power device 23, and the mobile threaded rod 214 continues to move up and down, the second rotating gear 225 continues to rotate, and the connecting rod 223 fixedly connected to the second rotating gear 225 continues to rotate. The tail end of the connecting rod 223 is fixedly connected to the bevel gear A321. The rotation of the connecting rod 223 drives the rotation of the bevel gear A321 connected to the connecting rod 223. After the bevel gear A321 rotates, the bevel gear B325 and the bevel gear C322 meshed with the upper and lower parts of the bevel gear A321 are driven to rotate. When the bevel gear B325 is meshed and rotated, the second stirring rod 326 fixedly connected to the bevel gear B325 rotates, and the lower end of the second stirring rod 326 is fixedly connected The second stirring claw 327 is designed to stir and mix the prepared solution in the solution storage barrel 31. The rotation of the bevel gear C322 drives the rotation of the first stirring rod 323 connected to the bevel gear C322. The middle position of the first stirring rod 323 is fixedly connected to the first stirring claw 324. The shape of the first stirring claw 324 plays a mixing and stirring role on the solution. The second stirring rod 326 is sleeved in the first stirring rod 323, so when the bevel gear A321 rotates, the bevel gear C322 and the bevel gear B325 that are meshed with the bevel gear A321 up and down rotate clockwise and counterclockwise in opposite directions, that is, the first stirring claw 324 and the second stirring claw 327 are in opposite directions when stirring, ensuring uniform mixing of the solution. At this time, the motor connected to the slider 12 is turned on again, and the moving speed is slowed down.

[0034] In the fifth step, the power device 23 is not turned off in the fourth step, so the power device 23 keeps moving back and forth, driving the rotating device 22 to keep rotating clockwise and counterclockwise, thereby driving the moving threaded rod 214 meshing with the rotating device 22 to move back and forth, and the moving threaded rod 214's up and down reciprocating motion drives the spraying mechanism 4 to move back and forth, ensuring that when spraying the crops, reciprocating spraying can be performed from top to bottom and then from bottom to top. Compared with the traditional single-direction spraying method, this reciprocating spraying ensures that the back of the leaves of the crops can also be sprayed, avoiding the situation where the pests and diseases that need to be disinfected on the back of the crops are not sprayed with pesticides, and ensuring that the spraying solution can fully cover the crops.

[0035] The sixth step, in the fourth step, through the fixed connection between the connecting rod 223 and the bevel gear A321, when the connecting rod 223 rotates, the bevel gear A321 is driven to rotate, and the rotation of the bevel gear A321 drives the bevel gear C322 and the bevel gear B325 meshing therewith to rotate, thereby driving the second stirring rod 326 and the first stirring rod 323 to rotate, and the rotation of the second stirring rod 326 and the first stirring rod 323 is used to continuously stir the prepared solution, and this process is always accompanied by the rotation of the connecting rod 223, that is, the entire device can realize continuous stirring of the prepared solution during the spraying process, thereby ensuring sufficient mixing of the solution and uniformity of the density of the solution sprayed on the crops, thereby improving the planting efficiency and quality.

[0036] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
