[0047] In order to solve the problems of the prior art, the present application makes improvements and innovations and proposes the following embodiments.

[0048] See also Figure 1 In some embodiments, a spray device for a greenhouse is provided, comprising:

[0049] The support structure 1 includes a support frame 101 fixedly arranged in a horizontal direction and a first support platform 104. The first support platform 104 is slidably arranged on the support frame 101 and can slide in the front-to-back direction relative to the support frame 101.

[0050] The lateral translation mechanism 2 includes a second support platform 207 and a support column 208. The second support platform 207 is slidably supported by the first support platform 104, and the second support platform 207 can slide in the left and right directions relative to the first support platform 104. One end of the support column 208 is fixed to the second support platform 207, and the other end of the support column 208 extends downward in the vertical direction; and

[0051] The spray assembly 3 includes a water tank 305, a water pump 301, a water distribution pipe 302, a water supply pipe 303 and a plurality of spray heads 304;

[0052] Among them, the water tank 305 is fixedly set on the first supporting platform 104, the water pump 301 is fixedly set on the second supporting platform 207, the water supply pipe 303 is arranged along the support column 208, the water distribution pipe 302 is arranged in the left and right directions and is connected with the water supply pipe 303, and a number of nozzles 304 are arranged at intervals on the water distribution pipe 302. The water inlet end of the water pump 301 is connected to the water tank 305, and the water outlet end of the water pump 301 is connected to the water distribution pipe 302.

[0053] In this example, the first support 104 can slide in the front-to-back direction relative to the support frame 101, and the lateral translation mechanism 2 is set so that the second support 207 can slide in the left-to-right direction relative to the first support 104, thereby realizing the movement of the spray assembly 3 in the front-to-back and left-to-right directions. Among them, by selecting and adjusting the capacity or loading amount of the water tank 305, regulating the operating frequency of the water pump 301, or selecting different specifications and models and arrangement numbers of the nozzles 304, it is possible to achieve fixed-quota irrigation or spraying of pesticides. In addition, the spray assembly 3 can move in multiple directions. By controlling the operation mode and range of the spray device, the quality and efficiency of the operation in the greenhouse planting area, whether it is spraying, water and fertilizer irrigation, or pesticide spraying, will be improved.

[0054] In some embodiments, see Figure 1 , the support structure 1 further includes: two first slide rails 102, a plurality of first sliders 108 and a first drive motor 106;

[0055] Two first slide rails 102 are arranged parallel and at the same height on the support frame 101. First sliders 108 are provided on both sides of the bottom of the first support platform 104, respectively, to slide in connection with the first slide rails 102. A first rack 107 is arranged along the front-to-back direction on one side of the support frame 101. A first drive motor 106 is fixedly mounted on a side of the first support platform 104 adjacent to the first rack 107. A first gear is provided on the output end of the first drive motor 106, and the first gear meshes with the first rack 107. Thus, the output shaft of the first drive motor 106 can be rotated to drive the first support platform 104 to move on the first slide rails 102, thereby achieving front-to-back movement of the spray device and spraying operation.

[0056] In some embodiments, see Figure 1 and Figure 2 The lateral translation mechanism 2 further includes: two second slide rails 206, a plurality of second sliders, a second drive motor 201, a first support base 202, a second support base 203, a screw rod 204 and a transmission slider 205;

[0057] Among them, two slide rails are arranged on the first supporting platform 104 along the left and right directions, a slider is set at the bottom of the second supporting platform 207 and is slidably connected to the second slide rail 206, the first support seat 202 and the second support seat 203 are arranged on both sides of the first supporting platform 104, and the two ends of the screw rod 204 are respectively connected to the first support seat 202 and the second support seat 203 for relative rotation, the second drive motor 201 is fixedly set on the outside of the first support seat 202, and the rotating shaft of the second drive motor 201 is coaxially fixed with one end of the screw rod 204, the bottom of the transmission slider 205 is fixedly connected to the second supporting platform 207, and the middle part of the transmission slider 205 is threadedly connected to the screw rod 204 by opening a threaded hole.

[0058] In this example, the second drive motor 201 drives the screw rod 204 to rotate, and the transmission slider 205 that is threadedly matched with the screw rod 204 slides left and right relative to the screw rod 204, thereby driving the second support platform 207 below to move in the left and right directions, that is, it can drive the spray assembly 3 to move and spray in the left and right directions, which is beneficial to improving the uniformity of spraying.

[0059] In some embodiments, see Figure 1 and Figure 3 A first drive motor support 105 is constructed on one side of the first support 104 adjacent to the first rack 107. The first drive motor support 105 is vertically sunken relative to the first support 104, and the first drive motor 106 is fixedly mounted on the first drive motor support 105. This allows the first drive motor 106 to be closer to the first rack 107 in the height direction, thereby making the device more compact and eliminating the need to extend the motor shaft, which helps improve torque transmission efficiency.

[0060] In some embodiments, see Figure 4 、 Figure 5 and Figure 6 , the greenhouse spray device also includes:

[0061] Lifting assembly 4, which includes a fixed frame 401, a third slider 406, a third drive motor 402, a worm 403, a turbine 404, and a second gear 405; the fixed frame 401 is a hollow rectangular frame, and the worm 403, the turbine 404, and the second gear 405 are fixed within the fixed frame 401 so as to be rotatable relative to each other. The third drive motor 402 is fixedly mounted on an outer wall of one side of the fixed frame 401;

[0062] The support column 208 is provided with two third slide rails 2010 arranged in the vertical direction and a second rack 209;

[0063] Among them, the fixed frame 401 is slidingly connected to the third slide rail 2010 by setting a number of third sliders 406, the drive motor is coaxially fixed to one end of the worm 403, the turbine 404 is coaxially fixed to the second gear 405, the worm 403 is meshed with the turbine 404, the second gear 405 is meshed with the second rack 209, and the water supply pipe 303 is fixed to one side of the fixed frame 401.

[0064] In this example, driven by the third drive motor 402, the second gear 405 engages with the second rack 209 to drive the spray assembly 3 as a whole to move up and down, which can avoid taller plants, or the height of the spray assembly 3 can be adjusted to achieve adjustment of the height spraying range, thereby improving the flexibility and operability of the device and helping to improve production efficiency.

[0065] In some embodiments, see Figure 5 , the greenhouse spray device also includes:

[0066] Several fixing buckles 306; the water supply pipe 303 is detachably fixed to one side of the fixing frame 401 by the fixing buckles 306, which is convenient for the disassembly, assembly and replacement of the spray component 3. The water inlet end of the water supply pipe 303 is connected to the water outlet end of the water pump 301 through a flexible pipe. The flexible pipe can choose a commonly used connecting pipe fitting of a hose to ensure that the spray component 3 is effectively connected to the water pump 301 when it moves, thereby improving the spray adjustment range and the stability of the device.

[0067] In some embodiments, see Figure 1 、 Figure 4 and Figure 5 , the greenhouse spray device also includes:

[0068] The water supply pipe 303 and the water distribution pipe 302 are arranged orthogonally to each other, and the middle part of the water distribution pipe 302 is connected to the lower end of the water supply pipe 303. The number and position of the nozzles 304 on both sides of the water distribution pipe 302 with the water supply pipe 303 as the boundary are the same, so that the water output on both sides of the spray assembly 3 can be maintained balanced, which is beneficial to improving the uniformity of the spraying operation. The nozzle 304 is tilted downward relative to the horizontal plane, which is beneficial to the atomization and water output of the nozzle.

[0069] In some embodiments, see Figure 1 and Figure 2 Two symmetrical guard plates 109 are arranged on the first supporting platform 104. The two guard plates 109 are enclosed to form a water tank 305 fixing position. The water tank 305 is fixed in the water tank 305 fixing position by threaded fasteners, which improves the installation firmness of the water tank 305 and provides conditions for replacement and maintenance.

[0070] In some embodiments, see Figure 1 and Figure 2 , the greenhouse spray device also includes:

[0071] Two first racks 107 and two first drive motors 106;

[0072] Among them, the two first racks 107 are arranged on both sides of the support frame 101 along the front-to-back direction, and the two first drive motors 106 are fixed on both sides of the first support platform 104. The output shafts of the two first drive motors 106 are respectively provided with first gears, and the first gears are each engaged with the adjacent first racks 107, and the two first drive motors 106 rotate synchronously.

[0073] In this example, by setting two first racks 107 and two first drive motors 106 that can be driven synchronously, the device is provided with bilateral walking traction, which is beneficial to improving the stability of the device in the forward and backward directions. The bilateral first drive motors 106 provide greater driving force, so that the load of the device can be effectively increased. For example, a larger load can be set, which means that the water tank 305 can be set with a larger water storage capacity, which is beneficial to improving production efficiency.

[0074] In another embodiment, an agricultural planting greenhouse is provided, which is provided with a spray device as described in the above embodiment, and the spray device is arranged horizontally above the crop planting area in the greenhouse.
