Description

Technical Field

[0001] This utility model relates to the field of axial flow fan technology, and in particular to an axial flow fan for greenhouse cultivation. Background Technology

[0002] Greenhouse cultivation is an agricultural production method carried out in a closed or semi-closed environment. It involves artificially controlling environmental factors such as light and temperature to provide suitable growing conditions for crops. This cultivation method is widely used in the production of vegetables, fruits, flowers, and other crops.

[0003] Currently, axial flow fans are used for ventilation circulation in greenhouses. However, axial flow fans can only perform a single ventilation function. Furthermore, during the ventilation process, they reduce the humidity inside the greenhouse, causing accelerated evaporation from plant leaves and affecting their water balance. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an axial flow fan for greenhouse cultivation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An axial flow fan for greenhouse cultivation includes an axial flow fan body, an installation component installed below the axial flow fan body, and a movable base provided below the installation component. Movable wheels are installed at the four corners of the movable base, and a driving mechanism is installed inside the movable base. A spraying mechanism is installed on the end surface of the axial flow fan body, and a water supply mechanism is connected inside the spraying mechanism.

[0007] Preferably, the mounting assembly includes a mounting base plate, which is mounted on the lower surface of the axial flow fan body and the upper surface of the mounting base plate, and a limit frame is fixed at the center of the surface of the mounting base plate.

[0008] Preferably, the driving mechanism includes a protective housing, the outer side of the movable base is fixedly connected to the protective housing, and a drive motor is installed inside the protective housing. The output end of the drive motor is fixedly connected to a reciprocating lead screw, and a reciprocating thread is formed at the center of the surface of the reciprocating lead screw. A moving block is fitted on the surface of the reciprocating thread, and the end of the moving block is fixedly connected to a rack. The surface of the rack meshes with the surface of a gear, and a drive shaft is fitted inside the gear.

[0009] Preferably, a limiting disc is symmetrically sleeved on the surface of the reciprocating lead screw, and the surface size of the limiting disc is larger than the surface size of the moving block.

[0010] Preferably, the upper part of the movable base is provided with a through hole adapted to the drive shaft, the drive shaft is installed in the movable base by bearings, and the upper end of the drive shaft is fixedly connected to the lower part of the mounting base plate.

[0011] Preferably, the spraying mechanism includes mounting buckles, and a water distribution pipe is installed on the end surface of the axial flow fan body through multiple mounting buckles. Multiple sets of atomizing nozzles are installed at equal intervals on the surface of the water distribution pipe, and a water supply pipe is connected to the bottom of the water distribution pipe.

[0012] Preferably, the water supply mechanism includes a water pump, the end of the water supply pipe is connected to the outlet of the water pump, and the inlet of the water pump is connected to the water storage tank through the water pump pipe. A water inlet is installed on the top of the water storage tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The device uses a water pump to draw water from the storage tank into the supply pipe. The water in the supply pipe is then atomized and sprayed out through the branch pipe and atomizing nozzles, which can assist in humidification during the ventilation process of the axial flow fan. The water tank can be easily replenished through the water inlet installed above the storage tank. The movable base and casters installed below facilitate the relocation of the axial flow fan.

[0015] The device can drive the reciprocating screw to rotate via a drive motor, which allows the moving block to move back and forth along the surface of the reciprocating thread. This allows the rack to move back and forth along the surface of the reciprocating thread, which in turn allows the gear to drive the shaft to rotate back and forth, thus increasing the spraying range of the axial flow fan body. Furthermore, the two limiting discs symmetrically fitted onto the surface of the reciprocating screw can limit the movement of the moving block. Attached Figure Description

The protective shell 51 is fixedly connected to the outside of the movable base 3, and a drive motor 52 is installed inside the protective shell 51. A reciprocating screw 53 is fixedly connected to the output end of the drive motor 52, and a reciprocating thread 54 is provided at the center of the surface of the reciprocating screw 53. The drive motor 52 can drive the reciprocating screw 53 to rotate the reciprocating thread 54. A moving block 55 is sleeved on the surface of the reciprocating thread 54, and the end of the moving block 55 is fixedly connected to the rack 56. The moving block 55 moves back and forth along the surface of the reciprocating thread 54, which facilitates the action of the rack 56. The surface of the rack 56 meshes with the surface of the gear 57, and a drive shaft 58 is sleeved inside the gear 57. The movement of the rack 56 can drive the drive shaft 58 to rotate.

[0025] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the reciprocating screw 53 is symmetrically fitted with a limiting plate 59. The surface size of the limiting plate 59 is larger than the surface size of the moving block 55. The limiting plate 59 can conveniently limit the function of the moving block 55.

[0026] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the upper part of the movable base 3 is provided with a through hole that matches the drive shaft 58. The drive shaft 58 is installed in the movable base 3 through a bearing. The upper end of the drive shaft 58 is fixedly connected to the lower part of the mounting base 21. Through the through hole opened on the upper part of the movable base 3, the drive shaft 58 can pass through the movable base 3 to drive the mounting base 21 to rotate.

[0027] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the spraying mechanism 6 includes mounting buckles 61. A branch water pipe 62 is installed on the end surface of the axial flow fan body 1 through multiple mounting buckles 61.

Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 The position of the axial flow fan body 1 can be moved and adjusted by the movable base 3 and the movable wheels 4. The axial flow fan body 1 can provide ventilation. The water pump 71 can pump water from the water storage tank 73 to the water supply pipe 64 through the water pumping pipe 72. The water can be atomized and sprayed through the branch water pipe 62 and multiple sets of atomizing nozzles 63. As the axial flow fan body 1 blows, it can increase the humidity in the greenhouse.
