Description

Technical Field

[0001] The utility model is applicable to the field of crop spraying, and provides a spraying device for agricultural product planting. Background Art

[0002] At present, the greenhouse planting technology has been widely used in agricultural product production. This enclosed environment can effectively protect crops from adverse weather conditions, such as extreme temperatures, insufficient precipitation, etc., thus ensuring a more stable growth environment for crops. In addition, greenhouse planting can also achieve high-density and high-efficiency crop planting, improve the yield per unit area, and meet the needs of large-scale production. By optimizing the environmental conditions in the greenhouse, greenhouse planting can effectively improve the quality and yield of agricultural crops and realize the continuous supply of high-quality agricultural products.

[0003] The current greenhouse spraying technologies mainly include automatic spraying systems and micro-spraying systems. These systems are usually equipped with spray heads, pipes, pumps, and control devices. By spraying water regularly, they can provide uniform water supply for crops. The spraying system can set different spraying modes and times to adapt to the needs of different crops, moisten plants more precisely, reduce water waste, and improve the humidity environment in the greenhouse, thereby promoting the healthy growth of crops.

[0004] Although the existing greenhouse spraying devices perform well in water supply, there are still deficiencies in the spraying of drugs and nutrient solutions. At present, the spraying of drugs and nutrient solutions usually requires manual operation. For example, manual spraying or manually adding the liquid medicine into the water tank for dilution and then connecting the spraying system for spraying. This operation is not only time-consuming and laborious, but also may lead to uneven concentrations of the liquid medicine and nutrient solution, affecting their effects. Therefore, how to improve the automation degree and operation convenience of drug and nutrient solution spraying is an urgent problem to be solved by the current spraying devices. Summary of the Utility Model

[0005] Aiming at the above defects, the purpose of the utility model is to provide a spraying device for agricultural product planting, aiming to solve the problems raised in the background art. The device includes a water outlet plate and a spraying plate fixedly connected to each other. A flow dividing plate that can slide between the water outlet plate and the spraying plate under the drive of a driving device is installed between the water outlet plate and the spraying plate; an inlet interface is installed on the water outlet plate, and a number of inlet slot holes are provided on the water outlet plate. An inlet channel is provided between the inlet slot holes and the inlet interface; a number of first through holes and second through holes are provided on the flow dividing plate at intervals, a medicine inlet interface is provided on the flow dividing plate, and a medicine inlet channel communicating the second through holes with the medicine inlet interface is provided inside the flow dividing plate; a number of spray head mounting holes corresponding to the inlet slot holes are provided on the spraying plate, and spray heads are fixedly connected to the spray head mounting holes.

[0006] Furthermore, the adjacent first through-holes and second through-holes are evenly spaced, and the spacing distance between the adjacent first through-holes and second through-holes is 1 / 2 of the spacing distance between the adjacent water inlet tank holes.

[0007] Furthermore, a row scale is provided on one side of the flow dividing plate, a gear box is fixedly connected to one side of the spraying plate, a driving gear is rotatably connected inside the gear box, the driving gear meshes with the row scale, and the driving gear is fixedly connected to the output end of the driving device.

[0008] Furthermore, a mounting plate is fixedly connected to the spraying plate, and the mounting plate is fixedly connected to the water outlet plate.

[0009] Furthermore, a cover plate is mounted on the gear box, and the cover plate is hingedly connected to the gear box.

[0010] Furthermore, a limit card slot is provided on the water outlet plate, a limit card strip corresponding to the limit card slot is provided on the flow dividing plate, and the limit card strip is embedded inside the limit card slot.

[0011] Furthermore, the driving device includes a reducer and a stepping motor mounted on the gear box. The reducer is provided with a transmission gear and a reduction gear that mesh with each other. The reduction gear is fixedly connected to the driving gear through a second rotating shaft, and the output end of the stepping motor is connected to the transmission gear through a rotating shaft.

[0012] Furthermore, a plurality of fixing seats are fixedly connected to the top of the water outlet plate.

[0013] In summary, during actual use, the device can be divided into two working states. When the stepping motor drives the flow dividing plate to be in the water spraying state, the first through-holes correspond to the spray heads on the spray head mounting holes, and the water is sprayed out, which can spray and irrigate crops; when the stepping motor drives the flow dividing plate to be in the medicine spraying state, the second through-holes correspond to the spray heads on the spray head mounting holes, and the water mixed with the liquid medicine is sprayed out, which can spray medicine while spraying the crops. On the other hand, the staff can finely control the position of the flow dividing plate by controlling the stepping motor, change the channel size at the transition between the first through-hole or the second through-hole and the spray head mounting hole, and control the water output of the spray. Thus, the device can not only conveniently spray and irrigate crops, but also spray pesticides and nutrient solutions on crops in the way of water-drug mixed flow. The mixed flow method can save the operation steps of the liquid medicine. By diluting and spraying the medicine inside the device, not only the medicine spraying is uniform, but also the medicine mixing time can be saved, and the production can be further simplified.

[0027] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0028] See Figures 1-9 , the objective of the present utility model is to provide a spraying device for agricultural product planting, which includes a water outlet plate 1 and a spraying plate 3 that are fixedly connected to each other. The water outlet plate 1 is arranged on the top of the spraying plate 3, and a flow dividing plate 2 is installed between the water outlet plate 1 and the spraying plate 3. The flow dividing plate 2 can slide along the length direction between the water outlet plate 1 and the spraying plate 3 under the drive of a driving device.

[0029] An inlet interface 12 is fixedly connected to the water outlet plate 1. A plurality of inlet slot holes 101 are arranged on one side of the water outlet plate 1 close to the flow dividing plate 2. An inlet channel 102 is arranged between the inlet slot holes 101 and the inlet interface 12. The inlet interface 12 is connected to a water pumping device through a pipeline. The water pumping device can pump water into the inlet channel 102 of the water outlet plate 1 through the pipeline and the inlet interface 12, and then enter each inlet slot hole 101.

[0030] A plurality of first through holes 201 and second through holes 202 that are spaced apart from each other are arranged on the flow dividing plate 2. The spacing distance between adjacent first through holes 201 and second through holes 202 is uniform, and the spacing distance between adjacent first through holes 201 and second through holes 202 is 1 / 2 of the spacing distance between adjacent inlet slot holes 101. Both the first through holes 201 and the second through holes 202 penetrate through the flow dividing plate 2. A medicine inlet interface 21 is arranged on the flow dividing plate 2. A medicine inlet channel 203 that communicates the second through hole 202 with the medicine inlet interface 21 is arranged inside the flow dividing plate 2. The medicine inlet interface 21 is connected to a medicine pumping device through a pipeline. The medicine pumping device can pump plant nutrient solution or other medicine liquids for planting into the medicine inlet interface 21, and the medicine liquid can enter the second through hole 202 through the medicine inlet channel 203.

[0031] A plurality of nozzle mounting holes 301 corresponding to the inlet slot holes 101 are arranged on the spraying plate 3, and a spray head 31 is fixedly connected to the nozzle mounting holes 301.

[0032] Thus, the flow dividing plate 2 that can slide between the water outlet plate 1 and the spraying plate 3 divides the device into two working states: the water spraying state and the medicine spraying state. When the device is in the water spraying state, the flow dividing plate 2 is driven by the driving device, so that the first through hole 201 on the flow dividing plate 2 corresponds to the water inlet tank hole 101. At this time, water is sprayed out in sequence through the water inlet tank hole 101, the first through hole 201 and the spray head 31 to spray and water the large area of plants below. When the device is in the medicine spraying state, the flow dividing plate 2 is driven by the driving device, so that the second through hole 202 on the flow dividing plate 2 corresponds to the water inlet tank hole 101. At this time, water enters the second through hole 202 through the water inlet tank hole 101 and is mixed with the liquid medicine, and then is sprayed out through the spray head 31, achieving the dual effects of spraying and watering and applying medicine at the same time.

[0033] Preferably, a row ruler 22 is provided on one side of the flow dividing plate 2, a gear box 4 is fixedly connected to one side of the spraying plate 3, a driving gear 40 is rotatably connected inside the gear box 4, and the driving gear 40 meshes with the row ruler 22. A driving device is fixedly connected to the top of the gear box 4, and the output end of the driving device is fixedly connected to the driving gear 40. Thus, the output end of the driving device drives the driving gear 40 to rotate, so as to drive the forward and backward movement of the flow dividing plate 2 and realize the switching of the two working states of the device.

[0034] Preferably, a mounting plate 30 is fixedly connected to the spraying plate 3, and the mounting plate 30 is fixedly connected to the water outlet plate 1. Specifically, the spraying plate 3 is fixedly connected to the water outlet plate through the mounting plate 30. To make the fixing effect better, multiple mounting plates 30 can be provided on the spraying plate 3, and the mounting plate 30 is on a different side from the water inlet interface 12 and the medicine inlet interface 21.

[0035] Preferably, a cover plate 41 is installed on the gear box 4, and the cover plate 41 is hingedly connected to the gear box 4. The cover plate 41 can be opened to maintain the internal driving gear 40.

[0036] Preferably, a limiting card slot 13 is provided on the water outlet plate 1, and a limiting card strip 23 corresponding to the limiting card slot 13 is provided on the flow dividing plate 2. The limiting card strip 23 is embedded inside the limiting card slot 13. The cooperation of the limiting card strip 23 and the limiting card slot 13 plays a limiting role, so that the flow dividing plate 2 can slide along the length direction of the water outlet plate 1.

[0037] Preferably, the driving device includes a reducer 5 and a stepping motor 6 installed on the gear box. The reducer 5 is provided with a transmission gear 52 and a reduction gear 53 that are meshed with each other. The reduction gear 53 is fixedly connected to the driving gear 40 through a second rotating shaft. The output end of the stepping motor 6 is connected to the transmission gear 52 through a rotating shaft 51. The number of teeth of the transmission gear 52 is less than that of the reduction gear 53. Thus, the purpose of speed reduction is achieved, and the control of the device is more accurate.

[0038] Preferably, a plurality of fixing seats 11 are fixedly connected to the top of the water outlet plate 1. The fixing seats 11 are used to fix the device to the support frame in the planting greenhouse and hoist the whole device to the top of the greenhouse.

[0039] In summary, during actual use, the device can be divided into two working states. When the stepping motor 6 drives the flow dividing plate 2 to be in the water spraying state, the first through hole 201 corresponds to the spray heads 31 on the spray head mounting holes 301, and water is sprayed out, which can spray and irrigate crops; when the stepping motor 6 drives the flow dividing plate 2 to be in the medicine spraying state, the second through hole 202 corresponds to the spray heads 31 on the spray head mounting holes 301, and water mixed with the liquid medicine is sprayed out, which can spray medicine while spraying the crops. On the other hand, the staff can finely control the position of the flow dividing plate 2 by controlling the stepping motor 6, and change the channel size at the transition between the first through hole 201 or the second through hole 202 and the spray head mounting hole 301 to control the water output of the spray. Thus, the device can not only conveniently spray and irrigate crops, but also spray pesticides and nutrient solutions on crops in the way of water and medicine mixed flow. The mixed flow method can save the operation steps of the liquid medicine. By diluting and spraying the medicine inside the device, not only the medicine is sprayed evenly, but also the medicine mixing time can be saved, which can further simplify the production.

[0040] Certainly, the present invention can also have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present invention.
