Description

Technical Field

[0001] This utility model relates to the field of fans, specifically a direct-drive fan for livestock farming. Background Technology

[0002] With the continuous development of animal husbandry, large-scale livestock farms now have increasingly higher requirements for ventilation in livestock sheds in order to provide fresh air for livestock in a timely manner.

[0003] Existing livestock fans are mainly divided into galvanized steel square livestock fans and fiberglass livestock fans in terms of structural materials. They can also be divided into belt-driven and direct-drive types in terms of transmission methods. Direct-drive fans use a motor to drive the fan blades, thereby expelling air from the farm and allowing outside air to enter, thus completing ventilation and cooling. However, during operation, the fan temperature can rise due to the outside temperature and its own operation. Once a certain threshold is reached, overheat protection will activate, causing the fan to stop working. This will stop ventilation, which may have a certain impact on livestock. Moreover, repairs are required after overheat protection, making it inconvenient to use.

[0004] Therefore, a direct-drive fan for livestock farming is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies and solve the problem that when a fan is in use, its temperature can rise due to external temperature and its own operation, causing overheating protection to activate and the fan to stop working once it reaches a certain threshold, resulting in the cessation of ventilation and potentially affecting livestock, and that repairs are required after overheating protection, making it inconvenient to use, this utility model proposes a direct-drive fan for livestock farming.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A direct-drive livestock breeding fan of this utility model includes a mounting frame, four mounting plates are fixedly connected to the outside of the mounting frame, an exhaust duct is fixedly connected between the four mounting plates, a heat dissipation assembly is provided on the outside of the mounting frame, the heat dissipation assembly includes a heat dissipation cylinder slidably connected to the inside of the mounting frame, the outside of the heat dissipation cylinder is slidably connected to the inside of the exhaust duct, a connecting plate is fixedly connected to the inside of the heat dissipation cylinder, a connecting rod is fixedly connected to the outside of the connecting plate, and a transmission cross is fixedly connected to the end of the connecting rod.

[0007] Preferably, a protective component is provided on the outside of the mounting frame, the protective component including louvers fixedly connected to the inside of the mounting frame, and a blocking net fixedly connected to the inside of the exhaust duct.

[0008] Preferably, a power assembly is provided inside the mounting frame. The power assembly includes a fan blade fixedly connected inside the mounting frame, a transmission rod rotatably connected to the outside of the fan blade, and a mounting cross fixedly connected to the outside of the transmission rod.

[0009] Preferably, the power assembly further includes a motor fixedly connected to the end of the transmission rod, the end of the motor being fixedly connected to a mounting cylinder, and the end of the mounting cylinder being fixedly connected to the outside of the barrier net.

[0010] Preferably, the mounting cylinder is hollow, with the hollow end of the mounting cylinder facing the barrier net.

[0011] Preferably, the heat sink has an air inlet groove inside, the air inlet groove is obliquely arranged, and the heat sink passes through the mounting frame and the exhaust duct respectively.

[0012] Preferably, the transmission cross is fixedly connected to the outside of the transmission rod, and the transmission cross is penetrated by the transmission rod.

[0013] The advantages of this utility model are:

[0014] 1. This utility model uses the rotation of the transmission cross to drive the connecting rod to move, which in turn drives the connecting plate to rotate along the transmission cross. This, in turn, drives the heat dissipation cylinder to rotate between the mounting frame and the exhaust duct. This allows the heat dissipation cylinder to exchange the outside air with the air inside the heat dissipation cylinder, and the outside air is drawn into the heat dissipation cylinder. This dissipates heat from the motor, preventing the motor from entering overheat protection mode. This extends the continuous working time of the motor and reduces the need for maintenance, thereby improving the ease of use of the device.

[0015] 2. By setting up louvers, this utility model can reduce the air pressure inside the device at the initial stage of exhaust, thereby accelerating the speed at which air from the farm enters the device. In addition, the louvers and the barrier net can block impurities such as garbage bags, so that they will not get tangled on the fan blades, thereby reducing the possibility of damage to the device and ensuring its normal operation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-5 As shown, a direct-drive livestock breeding fan includes a mounting frame 1. Four mounting plates 2 are fixedly connected to the outside of the mounting frame 1. Exhaust ducts 3 are fixedly connected between the four mounting plates 2. A heat dissipation assembly is provided on the outside of the mounting frame 1. The heat dissipation assembly includes a heat dissipation cylinder 4 slidably connected to the inside of the mounting frame 1. The outside of the heat dissipation cylinder 4 is slidably connected to the inside of the exhaust duct 3. A connecting plate 5 is fixedly connected to the inside of the heat dissipation cylinder 4. A connecting rod 6 is fixedly connected to the outside of the connecting plate 5. A transmission cross 7 is fixedly connected to the end of the connecting rod 6.

[0026] During operation, the rotation of the transmission cross 7 drives the connecting rod 6 to move, which in turn drives the connecting plate 5 to rotate along the transmission cross 7. This, in turn, causes the heat sink 4 to rotate between the mounting frame 1 and the exhaust duct 3, allowing the heat sink 4 to exchange the outside air with the air inside the heat sink 4. The outside air is then drawn into the heat sink 4, which dissipates heat from the motor 11, preventing the motor 11 from entering overheat protection mode. This extends the continuous working time of the motor 11 and reduces the need for maintenance, thereby improving the ease of use of the device.

[0027] The mounting frame 1 is equipped with a power assembly, which includes a fan blade 13 fixedly connected inside the mounting frame 1, a transmission rod 12 rotatably connected to the outside of the fan blade 13, and a mounting cross 14 fixedly connected to the outside of the transmission rod 12.

[0028] The power assembly also includes a motor 11 fixedly connected to the end of the transmission rod 12. The end of the motor 11 is fixedly connected to a mounting cylinder 10, and the end of the mounting cylinder 10 is fixedly connected to the outside of the barrier net 9.

[0029] During operation, the motor 11 drives the transmission rod 12 to rotate, which in turn drives the exhaust fan to rotate, thereby expelling the internal air from the exhaust duct 3.

[0030] The mounting cylinder 10 is hollow, with the hollow end of the mounting cylinder 10 facing the barrier net 9.

[0031] During operation, by making the mounting cylinder 10 hollow, the weight is reduced and the contact area between the mounting cylinder 10 and the air entering from the outside of the heat dissipation cylinder 4 can be increased, thereby accelerating the cooling speed of the motor 11.

[0032] The heat sink 4 has an air inlet slot inside, which is set at an angle. The heat sink 4 passes through the mounting frame 1 and the exhaust duct 3 respectively.

[0033] During operation, by opening an air inlet slot on the heat sink 4 and setting it at an angle, the heat sink 4 can bring in outside air when it rotates, thereby achieving the effect of cooling.

[0034] The transmission cross 7 is fixedly connected to the outside of the transmission rod 12, and the transmission cross 7 is penetrated by the transmission rod 12.

[0035] During operation, the rotation of the transmission rod 12 drives the transmission cross 7 to rotate.

[0036] Example 2

[0037] Please see Figure 3 As shown in the first embodiment, as another implementation of this utility model, a protective component is provided on the outside of the mounting frame 1. The protective component includes a louver 8 fixedly connected to the inside of the mounting frame 1, and a blocking net 9 fixedly connected to the inside of the exhaust duct 3.

[0038] During operation, the louvers 8 can reduce the air pressure inside the device at the beginning of exhaust, thereby accelerating the speed at which air from the farm enters the device. The louvers 8 and the baffle net 9 can also block impurities such as garbage bags, preventing them from getting tangled on the fan blades 13, thus reducing the possibility of damage to the device and ensuring its normal operation.

[0039] The working principle is that the motor 11 drives the transmission rod 12 to rotate, which in turn drives the exhaust fan to rotate, thereby causing the internal air to be discharged from the exhaust fan 3.

[0040] Meanwhile, the transmission rod 12 can drive the transmission cross 7 to rotate, thereby driving the connecting rod 6 to move, which in turn drives the connecting plate 5 to rotate along the transmission cross 7, thereby driving the heat sink 4 to rotate between the mounting frame 1 and the exhaust duct 3. This allows the heat sink 4 to exchange the outside air with the air inside the heat sink 4, and the outside air is drawn into the heat sink 4, thereby cooling the motor 11. This prevents the motor 11 from entering the overheat protection mode, thus extending the continuous working time of the motor 11 and reducing the possibility of maintenance, thereby improving the ease of use of the device.
