Description

Technical Field

[0001] This utility model relates to the field of micro-tiller technology, and in particular to a micro-tiller. Background Art

[0002] In the process of modern agricultural mechanization, mini tillers, as small, lightweight, and multifunctional agricultural machinery, are widely used in various stages of field work, including cultivation, planting, and management, greatly improving agricultural production efficiency and reducing the labor intensity of farmers. With the continuous advancement of agricultural technology and the increasing demand for diversified planting, the design of mini tillers is also constantly being innovated and optimized to meet the usage needs of different soil types, crop varieties, and specific operating conditions.

[0003] Traditional mini-tillers are typically equipped with a fixed working shaft configuration, such as front wheels for mobility and stability, and rear blades or other agricultural implements for operation.

[0004] However, this fixed configuration limits the versatility and flexibility of the mini tiller. When facing different working conditions, it is necessary to purchase multiple mini tillers of different types, resulting in low applicability of the device. Utility Model Content

[0005] The purpose of this utility model is to provide a micro-tiller that solves the problem that the fixed working shaft of traditional micro-tillers limits their function, makes them unsuitable for various working conditions, and requires different types of micro-tillers to adapt to different working conditions.

[0006] To achieve the above objectives, this utility model provides a micro-tiller, including a frame, a first working shaft, a second working shaft, and a drive assembly. The first working shaft is rotatably mounted on the frame, and the second working shaft is rotatably mounted on the frame. The drive assembly is disposed on the frame and drives the first and second working shafts to rotate. The system also includes a working assembly. The working assembly includes a first traveling wheel, a ditch opener, a rotating rod, a depth limiting wheel, and an adjustment assembly. The first traveling wheel is detachably connected to the first working shaft and disposed on the first working shaft. The ditch opener is detachably connected to the second working shaft and disposed on the second working shaft. The rotating rod is rotatably connected to the frame and located on one side of the frame. The adjustment assembly is disposed on the rotating rod, and the depth limiting wheel is slidably connected to the rotating rod via the adjustment assembly.

[0007] The adjustment assembly includes a fixed sleeve and a sliding rod. The fixed sleeve is fixedly connected to the rotating rod and is located at the end of the rotating rod away from the frame. The sliding rod is slidably connected to the fixed sleeve and rotatably connected to the depth-limiting wheel, and is disposed on the fixed sleeve.

[0008] The fixing sleeve has a positioning hole, which is located on one side of the fixing sleeve and extends through the fixing sleeve; the slide rod has a limiting hole, which is located on the side of the slide rod near the positioning hole, and the limiting hole cooperates with the positioning hole.

[0009] The drive assembly includes an engine and a transmission component. The engine is connected to the frame and located on one side of the frame. The transmission component is connected to the output end of the engine and to the first working shaft and the second working shaft.

[0010] The working components include a second traveling wheel and a tillage blade. The second traveling wheel is detachably connected to the second working shaft and is mounted on the second working shaft. The furrow opener is detachably connected to the first working shaft and is mounted on the first working shaft.

[0011] This utility model discloses a micro-tiller. When ditching and ridging operations are required, the first traveling wheel and the ditcher are respectively mounted on the first working shaft and the second working shaft. The drive assembly drives the first working shaft and the second working shaft to rotate, thereby driving the first traveling wheel and the ditcher to rotate. The traveling wheel drives the frame to move, which in turn moves the device. During rotation, the ditcher's cutting edge cuts into the soil, forming the required furrows. At the same time, the depth-limiting wheel ensures that the furrows dug by the ditcher are of uniform depth. During operation, the drive assembly adjusts the torque of the first working shaft and the second working shaft. When encountering harder soil, the drive assembly increases the torque output to ensure that the ditcher can cut into the soil smoothly; while in soft soil, the torque is appropriately reduced to avoid excessive damage to the soil structure. After the operation is completed, the ditcher and the first traveling wheel are removed from the first working shaft and the second working shaft, respectively, and other working components are installed for the next stage of agricultural operations. This achieves the purpose of adapting the device to different working conditions. Attached Figure Description

DETAILED DESCRIPTION

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] First embodiment:

[0020] Please see Figure 1 and Figure 2 ,in Figure 1 This is a schematic diagram of the overall structure of a mini tiller. Figure 2 This is a top view of a micro-tiller.

[0021] This utility model provides a micro-tiller, including a frame 101, a first working shaft 102, a second working shaft 103, a drive assembly 104, and a working assembly 105. The working assembly 105 includes a first traveling wheel 106, a ditch opener 107, a rotating rod 108, a depth limiting wheel 109, and an adjustment assembly 110. The adjustment assembly 110 includes a fixing sleeve 111 and a sliding rod 112. The fixing sleeve 111 has a positioning hole 113, and the sliding rod 112 has a limiting hole 114. The drive assembly 104 includes an engine 115 and a transmission component 116. By installing traveling wheels or different tools on the first working shaft 102 and the second working shaft 103, and by adjusting the speed and torque of the first working shaft 102 and the second working shaft 103 through the drive assembly 104, the device can adapt to different working conditions and improve its applicability. It is understood that the aforementioned solution can be used to adapt the device to different working conditions, and can also be used to adjust the height of the depth limiting wheel 109.

[0022] In this specific embodiment, the first working shaft 102 is rotatably mounted on the frame 101, the second working shaft 103 is rotatably mounted on the frame 101, and the drive assembly 104 is disposed on the frame 101 and drives the first working shaft 102 and the second working shaft 103 to rotate. The drive assembly 104 can adjust the speed and torque of the first working shaft 102 and the second working shaft 103 to adapt to different working conditions.

[0023] The first traveling wheel 106 is detachably connected to the first working shaft 102 and mounted on the first working shaft 102. The trencher 107 is detachably connected to the second working shaft 103 and mounted on the second working shaft 103. The rotating rod 108 is rotatably connected to the frame 101 and located on one side of the frame 101. The adjusting assembly 110 is mounted on the rotating rod 108. The depth-limiting wheel 109 is slidably connected to the rotating rod 108 via the adjusting assembly 110. The adjusting assembly 110 is used to adjust the height of the depth-limiting wheel 109. When trenching and ridging operations are required, the first traveling wheel 106 and the trencher 107 are respectively mounted on the first working shaft 102 and the second working shaft 103. The driving assembly 104 drives the first working shaft 102 and the second working shaft 103 to rotate, thereby driving the first traveling wheel 106 and the trencher 107. 7. Rotation causes the first traveling wheel 106 to drive the frame 101 to move, thereby moving the device. During rotation, the ditch opener 107's blade cuts into the soil, forming the required trenches. Simultaneously, the depth-limiting wheel 109 ensures that the trenches dug by the ditch opener 107 are of uniform depth. During operation, the drive assembly 104 adjusts the torque of the first working shaft 102 and the second working shaft 103. When encountering relatively hard soil, the drive assembly 104 increases the torque output to ensure that the ditch opener 107 can smoothly cut into the soil; while in soft soil, the torque is appropriately reduced to avoid excessive damage to the soil structure. After the operation is completed, the ditch opener 107 and the first traveling wheel 106 are removed from the first working shaft 102 and the second working shaft 103 respectively, and other working components 105 are installed to carry out the next stage of agricultural operation; thus achieving the purpose of adapting the lifting device to different working conditions.

[0024] Secondly, the fixed sleeve 111 is fixedly connected to the rotating rod 108 and is located at the end of the rotating rod 108 away from the frame 101; the sliding rod 112 is slidably connected to the fixed sleeve 111 and rotatably connected to the depth limiting wheel 109, and is disposed on the fixed sleeve 111.

[0025] Meanwhile, the positioning hole 113 is provided on one side of the fixed sleeve 111 and passes through the fixed sleeve 111; the limiting hole 114 is provided on the side of the slide rod 112 near the positioning hole 113, and the limiting hole 114 cooperates with the positioning hole 113.

[0026] By sliding the slide rod 112 against the fixed sleeve 111, the depth limiting wheel 109 can be raised and lowered, thereby adjusting the height of the depth limiting wheel 109. When the height of the depth limiting wheel 109 is adjusted to the correct position, the bolt is passed through the positioning hole 113 on the fixed sleeve 111 and threadedly connected to the limiting hole 114 on the slide rod 112, thereby fixing the slide rod 112 and the depth limiting wheel 109.

[0027] In addition, the engine 115 is connected to the frame 101 and located on one side of the frame 101; the transmission component 116 is connected to the output end of the engine 115 and to the first working shaft 102 and the second working shaft 103; the engine 115 outputs power to the transmission component 116, and the transmission component 116 outputs power to the first working shaft 102 and the second working shaft 103 respectively. At the same time, the transmission component 116 can adjust the speed and torque of the first working shaft 102 and the second working shaft 103, thereby adapting to different land and working conditions.

[0028] Second embodiment:

[0029] Based on the first embodiment, please refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the overall structure of the micro-tiller in the second embodiment. Figure 4 This is a top view of the micro-tiller of the second embodiment. The working component 105 of this embodiment includes a second traveling wheel 201 and a tillage blade 202.

[0030] In this specific embodiment, the second traveling wheel 201 is detachably connected to the second working shaft 103 and is mounted on the second working shaft 103; the furrow opener 107 is detachably connected to the first working shaft 102 and is mounted on the first working shaft 102; when tillage is required, the sliding rod 112 and the depth limiting wheel 109 are disassembled, the first traveling wheel 106 and the furrow opener 107 are disassembled, the second traveling wheel 201 is mounted on the second working shaft 103, and the tillage blade 202 is mounted on the first working shaft 102, while simultaneously... The drive assembly 104 drives the first working shaft 102 and the second working shaft 103 to rotate, thereby driving the second traveling wheel 201 and the tilling blade 202 to rotate, so that the second traveling wheel 201 can drive the device to move, while the tilling blade 202 performs tilling operations on the soil; meanwhile, the component names "first traveling wheel 106" and "second traveling wheel 201" in this application are mainly for the convenience of describing and distinguishing the traveling wheels installed on the working shaft of the micro-tiller in different working states. In actual applications, these two traveling wheels may be the same in structure and function, or they may be customized according to specific needs.

[0031] When using the micro-tiller of this utility model, the user can flexibly select and install suitable working components 105 according to specific agricultural operation needs; for example, when performing ditching and ridging operations, the user can install the first walking wheel 106 and the ditch opener 107 onto the first working shaft 102 and the second working shaft 103 respectively. Then, the power is transmitted to the first working shaft 102 and the second working shaft 103 through the drive component 104, driving the first walking wheel 106 and the ditch opener 107 to rotate. At this time, the first walking wheel 106 will drive the micro-tiller to move in the field, while the ditch opener 107 will cut into the soil and form the required furrows; at the same time, the depth limiting wheel 109 is set at a suitable height through the adjustment component 110 to ensure that the depth of the furrows is uniform; when the working environment changes... When the requirements for soil texture or furrow depth vary, the user can adjust the speed and torque of the first working shaft 102 and the second working shaft 103 through the speed change function of the drive component 104 to adapt to different working conditions. When tillage is required, the first traveling wheel 106 and the furrow opener 107 are removed from the working shaft, and then the second traveling wheel 201 and the tilling blade 202 are installed. In this way, the mini tiller can move stably in the field under the drive of the second traveling wheel 201, while the tilling blade 202 will perform deep tillage. Similarly, the user can adjust the speed and torque of the drive component 104 according to the requirements of soil texture and tillage depth to obtain the best working effect. This achieves the purpose of adapting to different working conditions and improving the applicability of the device.

[0032] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
