[0003] At present, when spraying pesticides, the spraying device sprays the pesticides through a conduit. When spraying pesticides on grains, the existing conduit has a fixed length and is not easy to extend and retract, which reduces its spraying efficiency. Therefore, a grain planting spraying device with a telescopic structure is designed. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a grain planting spraying device with a telescopic structure to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model proposes a grain planting spraying device with a telescopic structure, comprising a bottom plate, a placement frame is provided on the top of the bottom plate, two support plates are fixedly installed on the inner wall of the placement frame, and water tanks are fixedly installed on the tops of the two support plates;

[0006] A telescopic mechanism is provided inside the placement frame, and the telescopic mechanism includes a motor, a screw, a moving block, a connecting plate, a conduit and a nozzle. A motor is fixedly installed on the bottom of the inner wall of the placement frame, a screw is fixedly installed on the output shaft of the motor, the outer ring of the screw is threadedly connected to the moving block, a connecting plate is fixedly installed on one side of the moving block, a conduit is fixedly provided on one side of the connecting plate, and a nozzle is fixedly provided on the outer ring of the conduit.

[0007] In one example, a fixed shaft is rotatably connected to the bottom of one side of the inner wall of the placement frame, and a winding roller is fixedly installed on the outer ring of the fixed shaft.

[0008] In one example, a hose is fixedly installed on one side of the water tank, the hose is wound around a winding roller, and the other end of the hose is connected to a conduit sleeve.

[0009] In one example, a second bevel gear is fixedly mounted on one end of the fixed shaft away from the placement frame.

[0010] In one example, a first bevel gear is fixedly mounted on the outer ring of the screw rod, and the first bevel gear is meshingly connected with the second bevel gear.

[0011] In one example, a limiting plate is fixedly installed on the bottom of the moving block, and the limiting plate is slidably connected to the bottom of the placement frame.

[0012] The grain planting spraying device with a telescopic structure proposed by the utility model can bring the following beneficial effects:

[0013] 1. The grain planting spraying device with a telescopic structure drives the screw rod to rotate by starting the motor, and the rotation of the screw rod drives the moving block to move, which drives the guide tube to move through the connecting plate, and the nozzle is extended and retracted, so that more grains can be sprayed with medicine, thereby accelerating the grain spraying rate.

[0014] 2. This grain planting spraying device with a telescopic structure drives the first bevel gear to rotate by rotating the screw. Since the first bevel gear is meshingly connected with the second bevel gear, it can drive the fixed shaft to rotate, and drive the winding roller to rotate, thereby releasing the telescopic hose, facilitating its extension and retraction, and achieving better spraying effect.

DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0021] like Figure 1 to Figure 3 As shown, the embodiment of the utility model proposes a grain planting spraying device with a telescopic structure, comprising a bottom plate 1, a placement frame 2 is provided on the top of the bottom plate 1, two support plates 4 are fixedly installed on the inner wall of the placement frame 2, and a water tank 3 is fixedly installed on the top of the two support plates 4;

[0022] A telescopic mechanism is provided inside the placement frame 2, and the telescopic mechanism includes a motor 11, a screw rod 10, a moving block 9, a connecting plate 8, a conduit 6 and a nozzle 7. The motor 11 is fixedly installed on the bottom of the inner wall of the placement frame 2, the screw rod 10 is fixedly installed on the output shaft of the motor 11, the outer ring of the screw rod 10 is threadedly connected to the moving block 9, a connecting plate 8 is fixedly installed on one side of the moving block 9, a conduit 6 is fixedly provided on one side of the connecting plate 8, and a nozzle 7 is fixedly provided on the outer ring of the conduit 6.

[0023] Specifically, a fixed shaft 14 is rotatably connected to the bottom of one side of the inner wall of the placement frame 2 , and a winding roller 15 is fixedly installed on the outer ring of the fixed shaft 14 . The winding roller 15 is fixed by the fixed shaft 14 , and the winding roller 15 winds the hose 5 .

[0024] Specifically, a hose 5 is fixedly installed on one side of the water tank 3 , the hose 5 is wound around the winding roller 15 , and the other end of the hose 5 is sleeved with a conduit 6 , so that the medicine in the water tank 3 is introduced into the conduit 6 through the hose 5 .

[0025] Specifically, a second bevel gear 13 is fixedly mounted on one end of the fixed shaft 14 away from the placement frame 2 , and the fixed shaft 14 is driven to rotate by the rotation of the second bevel gear 13 .

[0026] Specifically, a first bevel gear 12 is fixedly mounted on the outer ring of the screw rod 10 , and the first bevel gear 12 is meshingly connected with the second bevel gear 13 . The first bevel gear 12 is rotated by the screw rod 10 , thereby driving the second bevel gear 13 to rotate.
