[0029] The following is combined Figures 1-3 The embodiments shown illustrate the technical solution of this utility model:

[0030] This utility model provides a spraying device for agricultural greenhouses, comprising: a water tank 2; an electric telescopic rod 3, fixedly installed adjacent to the water tank 2; and a spraying assembly 4, fixedly installed at the top of the electric telescopic rod 3. The spraying assembly 4 is connected to the water tank 2 and includes a water pipe 401, a spray pipe 402, and nozzles 403. One end of the water pipe 401 is connected to the spray pipe 402, and multiple nozzles 403 are arrayed on the spray pipe 402. The nozzles 403 are connected to the spray pipe 402, and the sidewall of the spray pipe 402 is connected to the electric telescopic rod 3. The top of the telescopic rod 3 is fixedly connected, and the end of the water pipe 401 away from the nozzle 403 is connected to the outlet of the water tank 2; there are two slide rails 5, which are symmetrically arranged and vertically arranged on both sides of the electric telescopic rod 3. The slide rails 5 are adjacent to the electric telescopic rod 3, and the spraying component 4 is slidably connected to the slide rails 5; the support rod 6 is fixedly arranged on both sides of the two slide rails 5 at their far ends; the connecting rod 7 is fixedly connected to the spraying component 4 at one end and detachably connected to the support rod 6 at the other end.

[0031] According to the present invention, a spraying device for agricultural greenhouses includes a water tank 2, an electric telescopic rod 3, a slide rail 5, and a support rod 6, which are fixedly mounted on the upper surface of a trolley 1.

[0032] Understandably, this utility model provides a spraying device for agricultural greenhouses. The height of the spraying component 4 can be adjusted by the electric telescopic rod 3. Both ends of the spraying component 4 are supported by the slide rail 5. Over time, it is prone to deformation. Therefore, by setting the support rod 6 and the connecting rod 7 to form a triangular support structure for the spraying component 4, the two ends of the spraying component 4 can be supported to ensure that the spraying component 4 will not deform. This ensures that the uniformity of the irrigation water or pesticide sprayed by the spraying component 4 is improved, thereby increasing the yield of crops.

[0033] The trolley 1 of this invention includes a base plate 101, rolling wheels 102, and a pusher 103. The base plate 101 is a rectangular plate for easy storage and cleaning. The rolling wheels 102 are fixedly mounted on the bottom surface of the base plate 101. When the pusher 103 is pushed, the rolling wheels 102 roll in the forward direction, driving the trolley 1 forward, thereby moving the spraying assembly 4 mounted on it forward. The movement of the spraying assembly 4 sprays the crops planted in the agricultural greenhouse. The height of the pusher 103 in this invention is matched with the height of a person's outstretched arm. The pusher 103 is located on the top of the base plate 101 near the right side. The pusher 103 is a U-shaped pusher 103, with its open end fixedly connected to the surface of the base plate 101. The top of the pusher 103 is also provided with an inclined angle to prevent workers from hitting the right side wall of the base plate 101 when pushing the trolley 1.

[0034] In this utility model, the water tank 2 and the electric telescopic rod 3 are fixedly installed on the surface of the base plate 101. The water tank 2 is rectangular in shape, and its volume is selected according to actual needs. The non-extending end of the electric telescopic rod 3 is fixedly installed on the upper surface of the base plate 101. The base plate 101 is provided with a pusher 103, the water tank 2 and the electric telescopic rod 3 from top to left. The electric telescopic rod 3 is located on the left side of the base plate 101, so that the spraying assembly 4 can spray the crops deep inside the agricultural greenhouse.

[0035] In this practical system, the spraying component 4 is fixedly installed at the top of the electric telescopic pole 3. As the electric telescopic pole 3 rises and falls, it can drive the spraying component 4 to rise and fall, thereby more evenly watering and spraying crops at different heights.

[0036] In this utility model, the slide rail 5 is vertically installed on the upper surface of the base plate 101. The guide rail of the slide rail 5 is opened on the left side wall of the slide rail 5 and is a convex guide rail. The spraying component 4 is slidably installed on the guide rail. There are two slide rails 5 in total. The two slide rails 5 are symmetrically arranged to facilitate the spraying component 4 to slide up and down with the electric telescopic rod 3. At the same time, it provides two support points to ensure that the spraying component 4 remains horizontal and does not easily deform.

[0037] In this utility model, the support rod 6 is fixedly installed on the left side of the upper surface of the base plate 101. There are also two support rods symmetrically arranged on the front and rear sides of the slide rail 5. The support rod 6 and the spraying assembly 4 are detachably connected by the connecting rod 7. One end of the connecting rod 7 is rotatably connected to the spraying assembly 4, and the other end of the connecting rod 7 is detachably connected to the support rod 6. Before the electric telescopic rod 3 extends or retracts, the connection between the connecting rod 7 and the support rod 6 needs to be disconnected. After the electric telescopic rod 3 has extended or retracted, the connecting rod 7 is fixed to the support rod 6, which can then provide support for the spraying assembly 4.

[0038] According to the present invention, a spraying device for agricultural greenhouses includes a water tank 2, an electric telescopic rod 3, a slide rail 5, and a support rod 6, which are fixedly mounted on the upper surface of a trolley 1.

[0039] In this utility model, the spraying component 4 includes a water pipe 401, a spraying pipe 402, and a nozzle 403. One end of the water pipe 401 is connected to the spraying pipe 402. The water pipe 401 is a rubber water pipe 401 and is long enough. The spraying pipe 402 is a metal water pipe 401, which reduces costs and also reduces the weight of the device. Water pipe 401 is a cylindrical hollow pipe, and spray pipe 402 is a semi-circular hollow pipe. Multiple nozzles 403 are arranged in an array on spray pipe 402. The nozzles 403 of spray pipe 402 are connected to spray pipe 402. The side wall of spray pipe 402 is fixedly connected to the top of electric telescopic rod 3. Sliding blocks are fixedly installed at corresponding positions of spray pipe 402 and two slide rails 5. The sliding blocks are matched with the guide rail shape of slide rail 5 and can slide up and down on the side wall of slide rail 5. When electric telescopic rod 3 stops extending and retracting, it is fixed below spray pipe 402 by linear guide rail locking block, which provides support for spray pipe 402 and prevents deformation after the weight of water entering spray pipe 402 increases. The length of the spray pipe 402 is matched to the width of the agricultural greenhouse. An array of nozzles 403 is positioned near the bottom of the fan-shaped section of the spray pipe 402. Multiple nozzles 403 are arranged in the array. No nozzles 403 are positioned where the spray pipe 402 corresponds to the bottom plate 101. The nozzles 403 are located on both sides of the slide rail 5 of the spray pipe 402. The two sections of the spray pipe 402 at both ends of the slide rail 5 are detachably and sealed to the middle pipe. After the spraying device is moved into the agricultural greenhouse, the spray pipe 402 is reconnected for spraying. The detachable design of the spray pipe 402 facilitates storage and easier access into the agricultural greenhouse.

[0040] According to the present invention, a spraying device for agricultural greenhouses is provided: an extension plate is fixedly provided at the bottom of the periphery of the spraying pipe 402, a connecting hole is provided through the extension plate, one end of the connecting rod 7 is rotatably connected to the extension plate through the connecting hole by a bolt fastener, and the other end of the connecting rod 7 is detachably connected to the support rod 6 by a locking slider.

[0041] In this utility model, an extension plate is fixedly provided at the bottom of the peripheral side of the spray pipe 402. The extension plate is relatively short to avoid increasing the weight of the spray pipe 402. A connecting hole is provided through the extension plate. One end of the connecting rod 7 is rotatably connected to the extension plate through the connecting hole by a bolt fastener. The other end of the connecting rod 7 is detachably connected to the support rod 6 by a locking slider. The surface of the support rod 6 is provided with an anti-slip coating and anti-slip texture to prevent the locking slider from slipping.

[0042] According to the present invention, a spraying device for agricultural greenhouses is provided: a medicine tank 201 is provided on the top of the water tank 2, a communication port is provided between the medicine tank 201 and the water tank 2, an electric baffle is rotatably provided in the communication port, an electric stirring rack and a water pump are provided on the side wall of the medicine tank 201 and inside the water tank 2, and a control switch is provided on the side wall of the water tank 2, the control switch being electrically connected to the electric baffle, the electric stirring rack and the water pump.

[0043] In this invention, a medicine tank 201 is installed on the top of the water tank 2. A communication port is provided between the medicine tank 201 and the water tank 2. An electric baffle is rotatably installed at the communication port. An electric stirring rack and a water pump are installed on the side wall of the medicine tank 201 and inside the water tank 2. A control switch is installed on the side wall of the water tank 2, and the control switch is electrically connected to the electric baffle, the electric stirring rack, and the water pump. First, an appropriate amount of pesticide is added to the medicine tank 201. Then, the control switch is operated to start the electric baffle. After all the pesticide has been added to the water tank 2, the electric baffle is closed and the electric stirring rack is started to stir. After stirring evenly, the water pump is started to synchronously push the cart 1 to spray the pesticide onto the crops through the nozzle 403.

[0044] The working principle of this utility model is as follows: First, water is added to the water tank 2 and pesticide is added to the medicine tank 201 at the same time. After both are full, the pesticide in the medicine tank 201 flows into the water tank 2 by rotating the electric baffle. After being stirred evenly by the electric stirring rack, the height of the spray pipe 402 is adjusted by the electric telescopic rod 3. After adjustment, the connecting rod 7 is fixed to the support rod 6 by the locking slider of the connecting rod 7, which provides support for both ends of the spray pipe 402 and prevents the spray pipe 402 from deforming after a long time.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
