Description

Technical Field

[0001] This application relates to the field of orchard frost protection machine technology, and more specifically, to an intelligent orchard frost protection machine. Background Technology

[0002] The intelligent orchard frost protection machine is connected to a temperature sensor through a control cabinet. When crops are exposed to low temperatures and frost, the machine can be turned on automatically or at set times. Utilizing the principle of air turbulence, it disrupts the inversion layer and blows out warm air to diffuse heat, effectively raising the surrounding temperature and thus reducing or preventing the damage of frost to crops.

[0003] Currently, thermal frost protection equipment on the market uses a fan connected to a fuel heater in conjunction with a raised platform oil tank to generate warm air and raise the ambient temperature. When used in orchards, a raised platform is usually erected to install the frost protection machine to increase its height. During use, oil needs to be added to the oil tank on the raised platform. However, the oil pipe will get tangled on the frost protection machine as it rotates continuously. Therefore, manual oil delivery or oil delivery via a lower oil pipe is used. Both of these methods require the user to climb onto the raised platform, which has limitations.

[0004] Therefore, an intelligent orchard frost protection machine is needed to solve the above problems. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the technical problems mentioned in the background section, some embodiments of this application provide an intelligent orchard frost protection machine, comprising: a connecting plate located at the top of a tower and a control cabinet located on the ground. The connecting plate includes a fixed plate fixedly mounted at the bottom, a rotating plate rotatably connected to the fixed plate, and circumferentially distributed fixed columns fixedly mounted on the rotating plate. A fixed steel frame is fixedly mounted at the upper end of each fixed column, and a fixed column is rotatably connected to the middle of the fixed steel frame. A heater and a fan are fixedly mounted on the flanges at both ends of the fixed column. A swing cylinder is fixedly mounted on the fixed plate, and the upper end of the swing cylinder is integrally poweredly connected to the fixed steel frame. An electrical control box is fixedly mounted on the fixed steel frame, and a wire connects the electrical control box to the control cabinet. The electrical control box is connected to the heater and the fan. The machine is electrically connected. Support frames are welded to both sides of the fixed steel frame. Oil tanks are installed on the support frames. The bottom ends of the two oil tanks are connected and an oil guide pipe is installed. A three-way valve is connected to the oil guide pipe. An oil delivery pipe is connected to the three-way valve. The connection ends of the oil delivery pipe and the electric wire are respectively located on both sides of the fixed steel frame. A sliding block is threaded on the fixed column. A limiting rod is fixed on the sliding block. The limiting rod is used to clamp and position the oil delivery pipe. Two slots are opened on the periphery of the fixed plate. Inserts are inserted into the slots. The inserts are fixed to the fixed plate with threaded parts. The oil delivery pipe and the electric wire extend downward through the slots and are in close contact with the inserts. The oil delivery pipe is bent with a margin between the limiting rod and the insert.

[0007] Furthermore, one of the oil tanks is fixedly provided with an oil filling port, the oil filling port is provided with an oil seal, the oil seal is equipped with a liquid level sensor, and the bottom end of the fixed steel frame is provided with a swing mechanism, the swing mechanism is provided with an eccentric connecting rod connected and fixed to the fixed column.

[0008] Furthermore, the control cabinet is connected to the electrical control box to control the working status of the heater, the fan, the swing mechanism, and the swing cylinder. An oil pump is provided on the ground and connected to the oil tank through a pipeline. The control cabinet is connected to the oil pump to control the start and stop of the oil pump.

[0009] Furthermore, both ends of the oil guide pipe extend downward from the lower ends of the two oil tanks to the horizontally arranged fixed steel frame at the bottom, and extend along the direction of the fixed steel frame. The fixed steel frame and the oil guide pipe are fixed together with cable ties.

[0010] Furthermore, a limiting plate is provided above the rotating disk, the fixed disk is fixed to the flange of the limiting plate, and bearings are respectively installed at the contact ends of the rotating disk with the fixed plate and the limiting plate.

[0011] Furthermore, at least two metal straps are attached to the oil filling port and the support frame.

[0012] Furthermore, at least two hooks are fixed to the top of the fixed steel frame, and the hooks are provided with through holes.

[0013] Furthermore, the oil pipeline is equipped with metal mesh to enhance strength and prevent twisting and flattening.

[0014] The beneficial effects of this application are as follows:

[0015] 1. By installing a swing cylinder at the bottom of the fixed steel frame, the swing cylinder is fixedly connected to the fixed plate and drives the fixed steel frame to rotate, thereby causing the fixed steel frame to rotate clockwise and counterclockwise. By providing wiring slack between the slot and the limit rod, oiling can be done at the oil tank without changing the existing wiring layout of the frostproof machine. This avoids the wiring tangling problem caused by continuous rotation, improves the reliability of the frostproof machine in removing frost from the surface of crops, further enhances the frostproof efficiency, and eliminates the need for manual climbing to add oil.

[0016] 2. The rotating disk is connected to the fixed disk and the limiting disk by a bearing rotatable connection, and a fixed column is fixedly installed at the upper end of the rotating disk. By installing a limiting rod on the fixed column, the oil pipe is hung on the limiting rod, thereby reducing the distance between the oil pipe and the wire and the center rotating part, thus shortening the margin of the oil pipe and the wire and maintaining the stability of the oil pipe and the wire.

[0017] 3. Connect the oil pipeline and power lines to the ground equipment. With the fixed steel frame rotating 360 degrees back and forth, the problem of the reel twisting during rotation is avoided. Attached Figure Description

The upper end of the fixed steel frame 12 is provided with a power output end and is fixedly connected to the bottom end of the fixed steel frame 12 to realize the rotation of the fixed steel frame 12 as a whole. The front and rear ends of the connecting cylinder 91 are respectively connected and fixed with a heater 10 and a fan 11 through flanges. The heater 10 includes a protective outer cylinder and a burner located at the inner end. The burner is connected to an oil tank 13 through a pipe. The fan 11 includes a protective outer shell and a blower located at the inner end. The blower is connected to an electrical control box 17 through an electric wire. The electrical control box 17 is electrically connected to the heater 10. Support frames 15 are welded on both sides of the fixed steel frame 12. An oil tank 13 is placed on the support frame 15.

The top end of the fixed steel frame 12 is fixedly installed with a hook 80 through a threaded part. The hook 80 has a through hole and is connected to the hook 80 for lifting and hoisting through a hoisting device.

[0038] Reference Figure 3 One of the oil tanks 13 is fixedly equipped with an oil filler port 14, which is equipped with a removable oil seal 20. A liquid level sensor 21 is installed on the oil seal 20. The liquid level sensor 21 is inserted into the oil tank 13 to detect the liquid level in the oil tank 13. A metal strap 22 is used to bind and limit the oil tank 13 and the support frame 15. The connecting plate 18 includes a fixed plate 30 at the bottom, a rotating plate 31 in the middle, and a limiting plate 32 at the top. The limiting plate 32 and the fixed plate 30 are fixed together by a flange. The rotating disk 31 is connected to the fixed disk 30 and the limiting disk 32 by bearings. The lower part of the fixed steel frame 12 is fixedly connected to the rotating disk 31. When the swing cylinder 40 is working, the rotating disk 31 rotates synchronously with the fixed steel frame 12. When the connecting disk 18 is installed on the ground, the user can easily add oil to the oil tank 13 through the oil filling port 14 after removing the oil seal 20 and removing the liquid level sensor 21. The liquid level at the left and right oil tanks 13 is maintained under the connection of the oil guide pipe 19.

[0039] Reference Figure 1-7A control cabinet 70 is installed on the ground, and the control cabinet 70 is connected to the electrical control box 17 to control the working status of the heater 10, fan 11, swing mechanism 16, and swing cylinder 40. An oil pump is installed on the ground and connected to the oil tank 13 through a pipeline. The control cabinet 70 is connected to the oil pump to control the start and stop of the oil pump. The two ends of the oil guide pipe 19 extend downward from the lower ends of the two oil tanks 13 to the bottom horizontally set fixed steel frame 12 and extend along the direction of the fixed steel frame 12. The fixed steel frame 12 and the oil guide pipe 19 are fixed with cable ties 62. A three-way valve 64 is fixed on the bottom horizontally set fixed steel frame 12. The three-way valve 64 is connected to the oil guide pipe 19 and the oil delivery pipe 63. The lower end of the electrical control box 17 is connected to the wire 65. The oil delivery pipe 63 and the wire 65 are distributed circumferentially. Sliding fittings are installed on the two fixed columns 90. The device includes a sliding block 60. A threaded component is installed on the fixed column 90 and threadedly connected to the sliding block 60 for positioning. A limiting rod 61 is fixed to the end of the sliding block 60 away from the fixed column 90. The lower ends of the oil pipe 63 and the wire 65 are respectively set close to each other on two fixed columns 90 on the same side. The limiting rod 61 has a T-shaped cross section and is clamped and fixed to the oil pipe 63 or the wire 65. Two slots 51 are opened on the periphery of the fixed plate 30. The oil pipe 63, the wire 65 and the plug 52 are inserted into the slots 51. The plug 52 is fixed to the fixed plate 30 by a threaded component. The end of the plug 52 inserted into the fixed plate 30 is clamped and fixed to the oil pipe 63 or the wire 65. The oil pipe 63 is bent between the limiting rod 61 and the plug 52. The bending allowance of the oil pipe 63 is for the fixed steel frame 12 to extend when it rotates.

[0040] The work and installation process is as follows:

[0041] The connecting plate 18 can be fixedly installed on the ground by a mounting bracket, or it can be fixedly connected to a high tower by a threaded part. In this application, it is fixedly connected to a high tower. A control cabinet 70 is installed on the ground. The control cabinet 70 is partially connected to the electrical control box 17 by wire or wireless means. In this application, it is connected by wire. After the power is turned on at the control cabinet 70, the leakage protection switch on the control cabinet 70 is pulled up to supply power to all modules of the equipment. Referring to the schematic diagram of the control box, the switch on the panel is adjusted to "local". First, turn on the power switch. Second, turn on the fan switch. Third, turn on the rotary switch. Fourth, turn on the heater switch. At this time, the defrosting machine enters the normal working state.

[0042] When the swing cylinder 40 is working, the rotating disk 31 rotates synchronously with the fixed steel frame 12. The level sensor 21 detects the oil level in the oil tank 13 and transmits the data to the control cabinet 70. The control cabinet 70 controls the switch of the main oil pump, thereby making the oil pump work to draw oil into the oil tank 13. The fixed disk 30 is fixed to the tower by threaded parts, and the swing cylinder 40 is fixedly connected to the fixed disk 30 by threaded parts. The rotating disk 31 rotates synchronously with the fixed steel frame 12 under the operation of the swing cylinder 40.

[0043] By rotating the fixed steel frame 12, the connecting cylinder 91, which is rotatably connected to the fixed steel frame 12, and the heater 10 and fan 11 connected to the front and rear ends of the connecting cylinder 91 revolve around the circumference. Through the operation of the swing mechanism 16, the heater 10, fan 11 and connecting cylinder 91 are controlled to swing up and down under the eccentric connecting rod structure. When the fan 11 is started, air is blown into the heater 10. After the air passes through the heater 10, the temperature is increased in the combustion state of the heater 10. Using the principle of air turbulence, the inversion layer is turbulent and warm air is blown out to diffuse heat energy, which can effectively increase the ambient temperature.

[0044] The frost protector is equipped with two sets of temperature sensors. The first, a power-operated temperature sensor, is located at the bottom of the controller box, and its temperature is displayed on the control panel of the control cabinet 70. The second is a solar-powered wireless temperature monitor, which connects to the control cabinet 70 wirelessly. The solar-powered wireless temperature monitor is mounted on the fruit trees. The operator can connect to the control cabinet 70 via a mobile app to remotely manage the orchard area under the control of the control cabinet 70. The mobile phone can achieve the same control effect as the control cabinet 70. It also has an automatic mode. In automatic mode, it can execute two strategies: "set time control start / stop" and "set temperature control start / stop". After clicking "automatic control", you can create your own strategy and select the current frost protector to use. Specifically, most frost damage occurs at 3 or 4 am or 4 or 5 am. By setting a timer for start / stop via mobile phone, the frost protector can work automatically. Alternatively, by setting the temperature according to the cold tolerance critical point of different growth stages of the plants, the machine can start when the temperature is lower than the set temperature of the solar-powered wireless temperature monitor, thus reducing manual operation.

[0045] The swing cylinder 40 offers four standard rotation angle options: 90°, 180°, 270°, and 360°. The appropriate rotation angle is selected according to specific needs. In this application, a 360° swing cylinder 40 is used. The swing cylinder 40 controls the fixed steel frame 12 to rotate clockwise and counterclockwise. The oil pipe 63 and the wire 65 extend downwards and connect to the oil pump or control cabinet 70 below. During operation, the fixed plate 30 remains stationary, thus keeping the ends of the oil pipe 63 and the wire 65 fixed at the fixed plate 30 stationary. The rotating plate 31 continues to rotate, thus causing the fixed column 90 fixed on the rotating plate 31 to rotate synchronously. The fixed column 90 drives the oil pipe 63 or the wire 65 to move around the circumference through the limit rod 61, and returns the bend at the oil pipe 63 and the wire 65 during the subsequent reverse rotation. The length of the bend is adjusted according to actual usage requirements.
