Description

Technical Field

[0001] This utility model belongs to the field of soil loosening machine technology, specifically relating to a soil loosening machine with an adjustable structure. Background Technology

[0002] Soil tillers improve soil structure and aeration, which helps crop roots to take root and absorb nutrients, thus promoting plant growth. Soil tillers play multiple roles in agriculture and landscaping.

[0003] Existing soil loosening machines loosen the soil by rotating rotary blades at high speeds. However, since the positions of the multiple rotary blades on the shaft surface are fixed, the positions of the rotary blades cannot be adjusted according to the loosening needs, resulting in low flexibility of use. Therefore, this utility model proposes a soil loosening machine with an adjustable structure. Utility Model Content

[0004] The purpose of this invention is to provide a soil loosening machine with an adjustable structure to solve the problem mentioned in the background art where the rotary tiller blades are fixed in position and cannot be adjusted.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soil loosening machine with an adjustable structure, including a machine head disposed at the bottom end of a telescopic rod;

[0006] The machine head is composed of a shaft and multiple rotary blades. Each rotary blade is composed of a blade and a sleeve. The sleeve is fixed to the inside of the blade. The blade is sleeved on the surface of the shaft. An installation mechanism is provided at the connection between the shaft and the sleeve. The installation mechanism is composed of multiple limiting components and symmetrically arranged fixing components. All of the multiple limiting components and symmetrically arranged fixing components are arranged between the sleeve and the shaft.

[0007] The multiple limiting components consist of limiting sliders and limiting grooves. The limiting grooves are formed on the surface of the shaft, and the limiting sliders are fixed to the inner wall of the sleeve. The limiting sliders and the limiting grooves are in an engaged state.

[0008] The symmetrically arranged fixing assembly consists of a screw, a hole A, and multiple holes B. The multiple holes B are respectively opened on the inner side of the shaft, the hole A is opened on the inner side of the sleeve, and the screw passes through the inner side of the hole A and the inner side of the hole B.

[0009] Preferably, the diameter of the screw is the same as the diameter of the hole B, and the distance between the symmetrically opened holes A is the same as the distance between every two holes B.

[0010] Preferably, the width of the limiting slider is the same as the width of the limiting groove, and the end cross-section of the limiting slider is rectangular.

[0011] Preferably, the length of the limiting slider is the same as the length of the sleeve.

[0012] Preferably, the telescopic rod has an auxiliary handle on its surface and a battery pack at its top.

[0013] Preferably, the surface of the telescopic rod is provided with a telescopic structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The designed mounting mechanism improves upon the previous soil loosening machine, which suffered from insufficient flexibility due to the fixed positions of multiple rotary blades and the inability to adjust their positions according to loosening needs. By setting up a mounting mechanism between the rotary blades and the shaft, the mounting positions of multiple rotary blades on the shaft surface can be adjusted arbitrarily, increasing the flexibility of use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a soil loosening machine with an adjustable structure, including a machine head 2 set at the bottom end of a telescopic rod 1;

[0022] The machine head 2 consists of a shaft 21 and multiple rotary tillers 22. Each rotary tiller 22 consists of a blade 221 and a sleeve 222. The sleeve 222 is fixed to the inside of the blade 221. The blade 221 is fitted onto the surface of the shaft 21. An installation mechanism is provided at the connection between the shaft 21 and the sleeve 222. The position of the rotary tiller 22 on the surface of the shaft 21 can be adjusted arbitrarily through the installation mechanism. The installation mechanism consists of multiple limiting components 211 and symmetrically arranged fixing components 212. The multiple limiting components 211 and the symmetrically arranged fixing components 212 are all arranged between the sleeve 222 and the shaft 21.

[0023] Multiple limiting components 211 consist of limiting sliders 2111 and limiting grooves 2112. The limiting grooves 2112 are formed on the surface of the shaft 21, and the limiting sliders 2111 are fixed to the inner wall of the sleeve 222. The limiting sliders 2111 and the limiting grooves 2112 are engaged. The limiting components 211 limit the rotary tiller 22 as it slides left and right on the surface of the shaft 21.

[0024] The symmetrically arranged fixing component 212 consists of a screw 2121, a hole A 2122, and multiple holes B 2123. The fixing component 212 secures the rotary tiller blades 22 after they have been moved. Multiple holes B 2123 are respectively opened inside the shaft 21, and hole A 2122 is opened inside the sleeve 222. The screw 2121 passes through the inner sides of holes A 2122 and B 2123. This designed mounting mechanism improves upon the previous method of using a soil loosener where the fixed positions of multiple rotary tiller blades 22 prevented adjustment according to loosening needs, resulting in insufficient flexibility. By setting up an mounting mechanism between the rotary tiller blades 22 and the shaft 21, the multiple rotary tiller blades 22 are secured to the shaft. The mounting position of surface 21 can be adjusted arbitrarily, increasing the flexibility of use. The diameter of screw 2121 is the same as the diameter of hole B2123. The distance between symmetrically opened holes A2122 is the same as the distance between every two holes B2123. The width of limiting slider 2111 is the same as the width of limiting groove 2112. The end cross-section of limiting slider 2111 is rectangular. The length of limiting slider 2111 is the same as the length of sleeve 222. The surface of telescopic rod 1 is provided with an auxiliary handle 3, which allows the operator to assist during operation. The top of telescopic rod 1 is provided with a battery pack. The surface of telescopic rod 1 is provided with a telescopic structure, which allows the length of telescopic rod 1 to be extended or retracted.

[0025] The working principle and usage process of this utility model are as follows: During the operation of this soil loosening machine, a lithium battery is used as a power source to drive the motor to rotate the rotary tiller blades 22 to loosen the soil. When it is necessary to adjust the position of multiple rotary tiller blades 22, the through screw 2121 is disassembled to disconnect the rotary tiller blades 22 from the shaft 21. Then, the rotary tiller blades 22 are moved left and right to the required position, so that the hole A2122 is aligned with the hole B2123 at the required position. Then, the screw 2121 is inserted to complete the installation operation of the rotary tiller blades 22 and the shaft 21, thus completing the position adjustment of the rotary tiller blades 22.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
