DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] As an important agricultural machinery, rotary tillers have been widely used. However, traditional rotary tillers lack an effective heat dissipation mechanism. Long-term and high-intensity work will cause the internal temperature of the rotary tiller to be too high, which not only affects the working efficiency of the motor, but also may shorten the service life of the motor.

[0036] In order to solve the problem that traditional rotary tillers lack an effective heat dissipation mechanism, the present embodiment provides a rotary tiller. By installing a fan on the transmission component and setting an air outlet and an air outlet channel, the fan is driven to rotate when the transmission component rotates, thereby actively dissipating the heat for the motor.

[0037] See also Figures 1 to 7 The present embodiment provides a rotary tiller, comprising: a motor housing 10; a drive assembly 20, the drive assembly 20 being installed inside the motor housing 10; wherein the drive assembly 20 comprises a motor 21 and a transmission assembly 22; a fan 30, the fan 30 being installed inside the motor housing 10, and the transmission assembly 22 running through the fan 30; a rotary machine blade 40, the rotary machine blade 40 being connected to the transmission assembly 22, and when the transmission assembly 22 rotates, it will drive the rotary machine blade 40 to rotate; wherein, when the drive assembly 20 is working, it will drive the transmission assembly 22 to rotate, and the rotation of the transmission assembly 22 can drive the fan 30 to rotate to help the motor 21 dissipate heat.

[0038] Specifically, in this embodiment, the transmission assembly 22 runs through the motor 21, and the motor 21 drives the transmission assembly 22 to rotate when it is working. Since the transmission assembly 22 is connected to the rotary machine blade 40, when the motor 21 is running, the rotary machine blade 40 will also rotate accordingly, thereby achieving the effect of plowing the land. A fan 30 is arranged in the motor housing 10, and the fan 30 is installed on the transmission assembly 22, so that when the motor 21 is running, the fan 30 will also rotate synchronously. The fan 30 converts the heat generated by the motor 21 into hot air and discharges it outside the motor housing 10 to achieve the purpose of effective heat dissipation. This design cleverly realizes that while the motor 21 drives the rotary machine blade 40, the fan 30 rotates synchronously without the need for additional power drive, which saves costs and improves the utilization efficiency of the power of the motor 21. The cleverness of this design lies in the realization of multiple functions, which provides a guarantee for the efficient operation of the equipment.

[0039] Furthermore, the motor housing 10 further includes: a motor housing body 11 ; an air inlet 12 , which is disposed on the top of the motor housing body 11 ; and at least one air outlet 13 , which is disposed on the side of the motor housing body 11 .

[0040] Specifically, when the air inlet 12 and the air outlet 13 are arranged on the motor housing body 11, a baffle with a grille structure is provided to prevent debris from entering the air inlet 12 and the air outlet 13. The air inlet 12 is arranged at the top of the motor housing body 11. When the fan 30 starts to work, fresh air can enter from the air inlet 12, pass through the motor 21 and reach the fan 30, thereby taking away the heat generated by the motor, and then the fan 30 discharges the hot air from the air outlet 13 arranged on the side. Such an arrangement can achieve a good heat exchange cycle in the motor housing body 11, ensuring that the heat generated by the motor will continue to dissipate outside the motor housing body 11.

[0041] Furthermore, the air outlet 13 includes: an air outlet 131, which is arranged on the side of the motor housing body 11; and an air outlet 132, which is arranged on the side of the motor housing body 11; wherein the air outlet 131 and the air outlet 2 132 are arranged corresponding to each other on the motor housing body 11.

[0042] Specifically, by arranging the air outlet 1 131 and the air outlet 2 132 on the motor housing body 11 corresponding to each other, the hot air discharge efficiency can be made higher, and the arrangement of two air outlets 13 can also promote the exhaust rate of the fan 30, thereby improving the heat dissipation efficiency.

[0043] Furthermore, the motor housing 10 also includes a motor mounting base 14; wherein the motor mounting base 14 is placed in the motor housing body 11; the fan 30, the drive assembly 20 and the transmission assembly 22 are installed in the motor mounting base 14, and the transmission assembly 22 is installed on the top of the motor mounting base 14 at one end close to the drive assembly 20.

[0044] Specifically, the motor housing body 11 has a large internal space, and the motor 21 needs to drive the transmission assembly 22 and the rotating machine blade 40. The motor 21 generates a large force when working. Adding a small motor mounting seat 14 to the motor housing body 11 can make the motor 21 more firmly installed.

[0046] Specifically, since the motor 21 is installed inside the motor mounting base 14, the fan 30 directly exhausts air to the outside, and the hot air will enter the motor housing body 11. Therefore, an air outlet channel 15 is installed between the motor mounting base 14 and the air outlet 13, so that the hot air inside the motor mounting base 14 can be directly discharged outside the motor housing body 11.

[0047] Furthermore, the air outlet channel 15 includes: an air outlet channel 151, one end of which is connected to the motor mounting base 14, and the other end is connected to the air outlet 1 131; an air outlet channel 2 152, one end of which is connected to the motor mounting base 14, and the other end is connected to the air outlet 2 132; wherein, when the fan 30 is working, the heat generated by the motor 21 is blown out through the air outlet channel 151 and the air outlet channel 2 152.

[0048] Specifically, there are corresponding air outlet 131 and air outlet 2 132 on the motor housing body 11. To ensure that hot air can pass through the air outlet 131 and the air outlet 2 132 normally, an air outlet channel 151 and an air outlet channel 2 152 are respectively provided, wherein the air outlet channel 151 helps to discharge the hot air in the motor mounting seat 14 from the air outlet 131, and the air outlet channel 2 152 helps to discharge the hot air in the motor mounting seat 14 from the air outlet 2 132. The air outlet channel 151 and the air outlet channel 2 152 are both trapezoidal pipes with gradually increasing diameters, with the small diameter end connected to the motor mounting seat 14, and the large diameter end connected to the air outlet 131 and the air outlet 2 132 respectively.

[0050] Specifically, in this embodiment, four connecting columns 162 are provided on the upper shell body 161, and the upper shell body 161 and the motor shell body 11 are connected by fasteners through the four connecting columns 162, and the connecting columns 162 themselves have a certain length, so that an air intake space can be formed between the upper shell body 161 and the motor shell body 11, which facilitates the entry of fresh air into the air inlet 12.

[0051] Furthermore, the motor housing 10 further includes a recessed portion 17 , which is disposed on the motor housing body 11 near the air inlet 12 ; when the upper housing 16 is mounted on the motor housing body 11 , the recessed portion 17 and the upper housing 16 form an air inlet passage.

[0052] Specifically, a recessed portion 17 is provided on the motor housing body 11, and the recessed portion 17 is connected to the air intake space formed between the upper shell body 161 and the motor housing body 11, so that fresh air can enter the air intake space more conveniently.

[0053] Furthermore, the upper shell 16 also includes a buckle member 164 , which is installed on the upper shell body 161 near the notch of the rear cover 163 .

[0054] Specifically, because the motor housing body 11 is provided with a recessed portion 17, when the upper housing body 161 is installed on the motor housing body 11, a portion of the upper housing body 161 will protrude, and this portion can be used to extract the rotary tiller. Therefore, installing the buckle 164 on the upper housing body 161 can make it more convenient and easier for the user to extract the rotary tiller.

[0055] Furthermore, the fan 30 includes: a lower base plate 31, a through hole is provided in the center of the lower base plate 31, and the transmission assembly 22 passes through the through hole; a fan blade 32, an end portion of the fan blade 32 away from the driving assembly 20 is connected to the lower base plate 31; a fixing ring 33, an end portion of the fan blade 32 close to the driving assembly 20 is connected to the fixing ring 33; wherein the lower base plate 31 and the fixing ring 33 jointly fix the fan blade 32.

[0056] Specifically, a through hole is provided at the center of the lower bottom plate 31, and the lower bottom plate 31 is a central protruding structure. In this embodiment, the fan blades 32 are vertically mounted on the lower bottom plate 31, so that the fan 30 can generate greater wind force. A fixing ring 33 is connected to the end of the fan blade 32 close to the drive assembly 20.
