[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1, such as Figure 1 - Figure 4 As shown, this utility model provides a highly adaptable micro-tiller with adjustable blade position, including a micro-tiller body 1. A lifting adjustment assembly 2 is connected to the surface of the micro-tiller body 1. The lifting adjustment assembly 2 includes a fixed frame 201, a motor 202 connected to one side of the fixed frame 201, a rotating rod 203 connected to the output end of the motor 202, first gears 204 connected to both sides of the rotating rod 203, second gears 205 connected to the bottom surfaces of both sets of first gears 204, and threaded rods 206 fixedly connected to the bottom of both sets of second gears 205. A lifting platform 207 is provided at the lower end of the fixed frame 201, and threaded holes 208 are provided on both sides of the lifting platform 207. Slider 209 is connected to each of the four corners of 07. Engine 210 is connected to the surface of lifting platform 207. The output end of engine 210 is connected to the blade body 211. Motor 202 is electrically connected to an external power source through a control switch. The output end of motor 202 is fixedly connected to rotating rod 203. The position and size of first gear 204 match the position and size of second gear 205. First gear 204 and second gear 205 are meshed. Threaded rod 206 is threadedly connected to lifting platform 207 through threaded hole 208. Slide rod 212 is connected to both the front and rear ends of fixed frame 201. Slide rod 212 is slidably connected to slider 209.

[0029] The effect achieved in Embodiment 1 is that when it is necessary to adjust the tillage depth of the tillage blade body 211, the reverse rotation function of the motor 202 can be activated, causing the output end of the motor 202 to drive the rotating rod 203 to reverse. When the rotating rod 203 reverses, it will drive the two sets of first gears 204 to reverse simultaneously. The reverse rotation of the first gears 204 will drive the two sets of second gears 205 to mesh and rotate in the opposite direction, so that the two sets of second gears 205 can drive the two sets of threaded rods 206 to rotate in the opposite direction. At this time, the two sets of threaded rods 206 will rotate in the opposite direction with the lifting platform 207 through the threaded hole 208. Then, by rotating the screw thread in the opposite direction, the lifting platform 207 moves downward. At this time, the slider 209 also slides on the surface of the slide rod 212. The lifting platform 207 will then drive the tiller body 211 to move downward, thereby achieving the purpose of tillage depth adjustment. When it is necessary to adjust the height of the tiller body 211 upward, the forward rotation function of the motor 202 is turned on, so that the lifting platform 207 drives the tiller body 211 to move upward, thus achieving the depth adjustment of the tiller body 211. This improves the stability during use and avoids the problem that traditional adjustment methods are prone to plate shaking, which affects the stability of tillage depth.

[0030] Example 2, as Figure 5 and Figure 6 As shown, a height adjustment assembly 3 is connected to the rear end of the main body 1 of the micro-tiller. The height adjustment assembly 3 includes a connecting frame 301. A T-shaped groove 302 is formed inside the connecting frame 301. Insertion holes 303 are equidistantly formed on the inner wall of the T-shaped groove 302. A T-shaped block 304 is inserted into the T-shaped groove 302. A gripper 305 is connected to the top of the T-shaped block 304. Slots 306 are formed on both sides of the T-shaped block 304. Two sets of springs 307 are connected inside the slots 306. Each of the 07 has a push rod 308 inserted inside. The rear ends of the two sets of push rods 308 are fixedly connected to handles 309. The front ends of the two sets of push rods 308 are fixedly connected to push plates 310. The surface of the push plate 310 is connected to a locking block 311. The push plate 310 and the spring 307 form an elastic structure. The inner wall of the T-shaped groove 302 is in contact with the outer surface of the T-shaped block 304. The T-shaped block 304 and the T-shaped groove 302 form a sliding connection. The locking block 311 and the insertion hole 303 form an insertion connection.

[0031] The effect achieved in Embodiment 2 is that when the height of the gripper 305 needs to be adjusted, both sets of grippers 309 can be pulled outwards simultaneously. This allows the grippers 309 to push the push plate 310 through the push rod 308 to compress the spring 307, and cause the locking block 311 to be pulled out of the insertion hole 303 at the current position. Then, the T-shaped block 304 is pulled upwards, allowing the T-shaped block 304 to slide and adjust inside the T-shaped groove 302. When the T-shaped block 304 has adjusted the gripper 305 to a suitable height, the grippers 309 are released, allowing the spring 307 to push the push plate 310 to insert the locking block 311 into the insertion hole 303 after adjustment and fix it in place. This makes it convenient for people of different heights to push the main body 1 of the micro-tiller for operation, avoiding the problem that the traditional gripper 305 cannot be adjusted and is not suitable for people of different heights.

[0032] Working principle: When adjusting the tillage depth of the tiller body 211, the engine 210 can be turned on to drive the rotating rod 203 to rotate, which in turn drives the lifting platform 207 to adjust its height through gear meshing, thereby realizing the depth adjustment of the tiller body 211. This improves the stability during use and avoids the problem of plate shaking and affecting tillage depth stability caused by traditional adjustment methods. When people of different heights use the gripper 305 to push the tiller body 1, they can pull the handle 309 outward to pull the locking block 311 out of the current insertion hole 303. Then, they can slide to adjust the length of the T-shaped block 304 to the appropriate position and automatically fix it. This makes it convenient for people of different heights to operate and avoids the problem that the traditional gripper 305 cannot be adjusted and is not suitable for people of different heights.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
