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. Example 1:

[0017] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of the lifting device used in an adjustable electric tiller. Figure 2 This is a schematic diagram of the bearing installation position. This utility model provides an adjustable lifting device for an electric micro-tiller: it includes a frame 101, a controller 102, and auxiliary components. The auxiliary components include a main arm 103, a secondary arm 104, a bearing 105, a rotating shaft 106, a first spacer 107, a second spacer 108, a bearing end cover 109, a locking screw ring 110, a DC electric push rod 111, a sealing component, and a implement connecting component. The sealing component includes a sealing plate 112 and a sealing cover 113, and the implement connecting component includes a connecting seat 114 and an implement connecting plate 115. This solution allows for rapid lifting of the micro-tiller, making it more convenient to use. It is understood that the aforementioned solution enables rapid lifting of the micro-tiller.

[0018] In this embodiment, a controller 102 is mounted on the frame 101. The frame 101 is connected to the frame of the agricultural machinery by bolts. The agricultural machinery matched in this application can directly adopt existing equipment in the prior art. Similarly, the controller 102 and the DC electric push rod 111 in this application can also directly adopt equipment disclosed in the prior art. In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this utility model does not involve the improvement of software and methods. The specific dimensions of the corresponding components in this application can be set as needed. Finally, after assembly, the frame 101, the main arm 103, and the auxiliary arm 104 in this application are provided with a corrosion-resistant coating on their outer surfaces. The corrosion-resistant coating can be anti-rust paint.

[0019] The main boom 103 is welded to the frame 101 and is arranged obliquely and symmetrically. The auxiliary boom 104 is connected to the end of the rotating shaft 106 by multiple bolts. The rotating shaft 106 is rotatably mounted on the main boom 103 via the bearing 105. The first spacer ring 107 and the second spacer ring 108 are respectively sleeved on the rotating shaft 106 and abut against the inner ring of the bearing 105. The bearing end cover 109 is detachably connected to the main boom 103 and abuts against the outer ring of the bearing 105. Near the first spacer ring 107, the locking screw ring 110 is threadedly connected to the rotating shaft 106 and abuts against the second spacer ring 108. The mounting end and connecting end of the DC electric push rod 111 are rotatably connected to the frame 101 and the auxiliary arm 104 respectively through a T-shaped pin and a nut, and are electrically connected to the controller 102. The sealing member is provided on both sides of the main arm 103, and the implement connecting member is provided on the end of the auxiliary arm 104 away from the frame 101 for the installation of rotary tillers. The main arm 103 is welded and fixed, and a bearing mounting cavity is provided at the top to facilitate the installation of the bearing 105. The bearing 105 is a deep groove ball bearing with dust covers on both sides. The outer ring of the bearing 105 near the auxiliary arm 104 is limited after installation by the bearing end cover 109. The inner ring on this side is limited by the cooperation of the first spacer ring 107 and the limiting disc on the rotating shaft 106. The end face of the rotating shaft 106 has multiple threaded mounting holes and corresponding pin holes evenly spaced in a ring to facilitate the fixing of the auxiliary arm 104 by positioning pins and bolts. The inner side of the auxiliary arm 104 has a U-shaped cavity structure to facilitate the installation of bolts and positioning pins on the rotating shaft 106. The second spacer ring 108 and the locking screw ring 110 cooperate to achieve connection and limitation between the rotating shaft 106 and the bearing 105, and the second spacer ring 108 does not contact the main arm 103. The DC electric push rod 111 is connected to the controller 102 through a working cable. The sealing component is used for auxiliary protection of the bearing 105. In practice, the rear end of the rotating shaft 106 for mounting the locking coil 110 is provided with a stepped optical shaft (not shown in the figure). The diameter of the stepped optical shaft is slightly smaller than the outer diameter of the external thread end, which facilitates the fitting of the locking coil 110. However, a retaining groove is provided on the optical shaft to facilitate the installation of a retaining spring. The retaining spring abuts against the end face of the locking coil 110 for limiting the locking coil 110. The inner surfaces of the first spacer 107 and the second spacer 108 are respectively provided with a 0.02mm-0.03mm fluorocarbon coating. Fluorocarbon coatings are widely used in surface coatings of various products, such as kitchen equipment, bicycles, automotive parts, sliding doors, etc. In addition, fluorocarbon coatings are also widely used in various industrial fields, medical equipment, and high-tech fields such as aerospace. This can improve the wear resistance of the first spacer 107 and the second spacer 108 during sliding installation.

[0020] Secondly, the sealing plate 112 is detachably connected to the main arm 103 and has a safe distance from the rotating shaft 106, and is located on the side of the main arm 103 away from the auxiliary arm 104; the sealing cover 113 is detachably connected to the main arm 103 and slidably connected to the rotating shaft 106, and is located on the side of the main arm 103 away from the sealing plate 112. The sealing plate 112 is fixed by bolts, the sealing cover 113 is fixed by bolts, and a clearance cavity is provided to avoid the bearing end cover 109. At the same time, a copper sleeve is press-fitted into the through hole that mates with the rotating shaft 106 for support. After installation, the sealing cover 113 does not contact the auxiliary arm 104.

[0021] Then, the connecting seat 114 is fixed to the auxiliary arm 104 and arranged symmetrically; the implement connecting plate 115 is used for connecting and installing the rotary tiller and is installed on the connecting seat 114. The connecting seat 114 is T-shaped and is fixed by bolts. The implement connecting plate 115 is connected to the connecting seat 114 by bolts and is provided with threaded holes for fixing the rotary tiller.

[0022] Finally, the controller 102 is mounted on the mounting support arm of the DC electric actuator 111 and can be fitted with a protective cover on the outside. The protective cover has a U-shaped cross-section with the opening facing downwards and is fixed by bolts from bottom to top. Cable holes can be provided on the side wall for connection.

[0023] When using this invention to quickly lift a micro-tiller, the device is first connected to the frame of the agricultural machine via the frame 101. The rotary tiller is installed on the implement connecting plate 115. When connected to an external power source, the controller 102 controls the extension and retraction of the DC electric push rod 111. The DC electric push rod 111 pulls the auxiliary arm 104 to rotate by retracting, thus lifting or lowering the micro-tiller quickly and efficiently, making it more convenient to use. Example 2:

[0024] like Figure 3 As shown, where Figure 3 This is a schematic diagram of the overall structure of an adjustable electric micro-tiller. Based on the first embodiment, this utility model provides an adjustable electric micro-tiller lifting device. The adjustable electric micro-tiller lifting device also includes a stabilizing component, which includes a main stabilizing arm 201 and an auxiliary stabilizing arm 202.

[0025] The main stabilizing arm 201 is welded to the frame 101 and symmetrically arranged; the auxiliary stabilizing arm 202 is welded and fixed to both the frame 101 and the main stabilizing arm 201. The two ends of the main stabilizing arm 201 are welded and fixed to the frame 101 to ensure installation stability, and the two ends of the auxiliary stabilizing arm 202 are also welded and fixed to ensure stability.

[0026] In this embodiment, the main stabilizing arm 201 and the auxiliary stabilizing arm 202 are provided to improve the stability of the DC electric push rod 111 after installation.
