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 tool in modern agriculture, rotary tillers have played an increasingly important role in agricultural production. However, current rotary tillers have problems such as heavy baffles and high baffle costs, which not only affects the user experience of the rotary tiller, but also affects the performance of the rotary tiller.

[0036] In order to solve the problems of excessive weight and high cost of the baffle of the rotary tiller, the present embodiment provides a rotary tiller, by installing the drive component on the baffle member and installing the transmission component on the reinforcement member, the baffle member and the reinforcement member can be installed together after they are independently assembled, thereby effectively reducing the complexity of installation.

[0037] See also Figures 1 to 7 The present embodiment provides a rotary tiller, comprising: a baffle member 10; a reinforcement member 20, wherein the reinforcement member 20 is connected to the baffle member 10; a drive assembly 30, wherein the drive assembly 30 comprises a drive housing 31, a motor 32 and a motor shaft 33, and when the drive housing 31 is installed on the baffle member 10, the motor shaft 33 passes through the baffle member 10 and the reinforcement member 20; a transmission assembly 40, wherein the transmission assembly 40 is connected to the motor shaft 33, and the transmission assembly 40 is installed on the reinforcement member 20; wherein the baffle member 10, the drive assembly 30 and the transmission assembly 40 are all fixed to the reinforcement member 20.

[0038] Specifically, in this embodiment, the baffle member 10 is made of plastic, and the reinforcement member 20 is made of metal. The baffle member 10 is used to block the splashing mud and sand when the rotary tiller is working, and the reinforcement member 20 is used to fix the drive assembly 30 and the transmission assembly 40. Because the drive assembly 30 and the transmission assembly 40 will generate large vibrations when working, the reinforcement member 20 made of metal can completely fix the drive assembly 30 and the transmission assembly 40. Therefore, the baffle member 10, the drive assembly 30 and the transmission assembly 40 are all fixed to the reinforcement member 20, and the reinforcement member 20 provides support. In addition, the overall installation steps of the rotary tiller will be more complicated. Therefore, in this embodiment, the baffle member and the reinforcement member are first placed after the transmission assembly in sequence, and then the baffle member, the reinforcement member and the transmission assembly are fixed together, which can effectively reduce the complexity of installation.

[0039] Furthermore, the driving housing 31 includes: an outer shell 311 , which is mounted on the baffle member 10 ; an inner shell 312 , which is disposed inside the outer shell 311 , which is mounted on the baffle member 10 , and the motor 32 and the motor shaft 33 are mounted inside the inner shell 312 .

The inner shell 312 provides installation support for the motor 32 to ensure that the motor 32 can run stably. In addition, when the outer shell 311 is installed on the baffle member 10, the inner shell 312 is wrapped inside, effectively protecting the motor 32 and its related components.

[0041] Furthermore, the rotary tiller also includes a control component 50, which includes a connecting rod 51 and at least one connecting hole 52; wherein the connecting hole 52 is arranged on the connecting rod 51.

Bolts can be inserted into the connecting holes 2 60, and then nuts and bolts can be used to completely fix the four of them together. Moreover, because the reinforcement member 20 is made of metal, the outer shell 311, the connecting rod 51, the baffle member 10 and the reinforcement member 20 can be firmly fixed to improve the operability of the rotary tiller.

[0047] Furthermore, the driving assembly 30 further includes at least one sealing member 34 , which is mounted on the housing 311 to cover the second connecting hole 60 of the housing 311 .

By providing the connection holes 2 60 and the connection holes 3 70, the drive assembly 30 can be installed first, and then the transmission assembly 40 can be installed, making the assembly of the rotary tiller easier.

[0051] Furthermore, the transmission assembly 40 includes: a transmission housing 41; a transmission component 42, the transmission component 42 is placed inside the transmission housing 41, and the transmission component 42 is connected to the motor shaft 33; a rotary tiller blade 43, and the rotary tiller blade 43 is installed on the transmission component 42; wherein, when the motor shaft 33 rotates, it will drive the transmission component 42 to rotate, and the rotary tiller blade 43 will rotate synchronously with the transmission component 42.

The transmission component 42 is connected to the motor shaft 33, and the rotary tiller blade 43 is installed on the transmission component 42, so that the rotary tiller blade 43 and the transmission component 42 can rotate synchronously.

[0053] Furthermore, the transmission component 42 includes a transmission shaft 421 and a coupling 422 ; wherein the coupling 422 connects and fixes the transmission shaft 421 and the motor shaft 33 , so that the transmission shaft 421 rotates synchronously with the motor shaft 33 .

[0054] Specifically, the coupling 422 is a metal cylinder with a hollow interior. The motor shaft 33 is inserted into one end of the coupling 422 and the transmission shaft 421 is inserted into the other end of the coupling 422, so that the transmission shaft 421 and the motor shaft 33 can be completely fixed.
