[0002] Mini tillers are small agricultural machines that are widely used in plains, mountains, hills, dry land, paddy fields, orchards, etc. due to their light weight and small size. They can be equipped with appropriate implements for operations such as pumping water, generating electricity, and spraying pesticides. The rear frame is an important component for supporting and stabilizing the machine. When changing tools, the rear frame effectively protects other components.

[0003] The existing mini-tillers have limited rear frame flexibility, which restricts their applicability and makes it difficult to meet the needs of different work tools. Utility Model Content

[0004] The purpose of this utility model is to provide a rear frame for a micro-tiller that is easy to install, in order to solve the problem that the existing technology is difficult to adjust flexibly, which limits the applicability of micro-tillers and makes it difficult to meet the needs of different work tools.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rear frame for a micro-tiller that is easy to install, comprising a mounting plate, a hydraulic cylinder mounted on the front of the mounting plate, a fixing frame mounted on the output end of the hydraulic cylinder, a square groove through which the fixing frame is formed, a height adjustment rod mounted inside the square groove, a fixing plug mounted inside the fixing frame, the fixing plug being used to fix the height adjustment rod and the fixing frame, a pin through which one end of the fixing plug is mounted, and the pin being located on one side of the fixing frame, a main support rod mounted on the front of the fixing frame, and fixing plates mounted on both outer walls of the main support rod.

[0010] Preferably, one end of the fixing plug is provided with a mounting hole three, which corresponds to the position of the pin.

[0011] Preferably, the fixing plate has a second mounting hole inside, which is used to install the working tool.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, by installing a height adjustment rod, a fixed frame, a hydraulic cylinder, a fixing plug, and a pin, allows the height adjustment rod to be vertically pushed into a square groove from below the fixed frame. The fixing plug then fixes the relative position of the height adjustment rod and the fixed frame. Next, the pin is inserted into the fixing plug to secure it, further enhancing the stability between the height adjustment rod and the fixed frame. Afterward, the required working tools are installed between the two sets of fixed plates. The height of the height adjustment rod relative to the fixed frame can be adjusted according to the actual height of the micro-tiller, the working tools to be installed later, and the user's needs.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides an embodiment of a rear frame for a micro-tiller that is easy to install, including a mounting plate 1. A hydraulic cylinder 2 is mounted on the front of the mounting plate 1. A fixing frame 3 is mounted on the output end of the hydraulic cylinder 2. A square groove is opened through the inside of the fixing frame 3. A height adjustment rod 6 is installed inside the square groove. A fixing plug 11 is installed inside the fixing frame 3. The fixing plug 11 is used to fix the height adjustment rod 6 and the fixing frame 3. A pin 13 is installed through one end of the fixing plug 11 and is located on one side of the fixing frame 3. A main support rod 4 is mounted on the front of the fixing frame 3. Fixing plates 5 are mounted on both outer walls of the main support rod 4.

[0024] When the rear frame is needed, insert bolts into the mounting plate 1 and screw them into the corresponding screw holes to fix the rear frame in the corresponding position on the tiller. Its main function is to ensure the overall stability of the tiller. The hydraulic cylinder 2 is welded to the front of the mounting plate 1, and the output end of the hydraulic cylinder 2 is connected to the back of the fixing frame 3. After fixing the mounting plate 1, push the height adjustment rod 6 vertically into the square groove from below the fixing frame 3. Adjust the height adjustment rod 6 to an appropriate height according to the actual height of the tiller, the tools to be installed later, and the user's needs. Then, use the fixing plug 11 to fix the relative position of the height adjustment rod 6 and the fixing frame 3. Next, insert the pin 13 into the fixing plug 11 to fix the fixing plug 11, further strengthening the stability between the height adjustment rod 6 and the fixing frame 3. After fixing the height adjustment rod 6, the corresponding tools can be installed according to the actual needs. Between the two sets of fixing plates 5, and due to the cooperation of the fixing frame 3, height adjusting rod 6, fixing plug 11 and pin 13, the height of the height adjusting rod 6 can be adjusted. When installing tools with a high height, remove the pin 13 and fixing plug 11, and adjust the height adjusting rod 6 towards the ground. When the height of the height adjusting rod 6 located below the fixing frame 3 meets the requirements of the tool, use the fixing plug 11 and pin 13 to fix it, so that the height adjusting rod 6 and the moving wheel assembly below can play a supporting role when installing tools in the future. This improves the flexibility of the rear frame to a certain extent and greatly increases the applicability of the device. It is convenient to stably support tools of different heights and sizes. The overall assembly of the rear frame is simple and easy to install and disassemble. The hydraulic cylinder 2 can be extended according to the use requirements, thereby changing the position of the crossbar 7 and the tool to meet different operation requirements and improve the applicability of the device.

[0025] The bottom end of the height adjustment rod 6 is equipped with a crossbar 7, and the bottom of the crossbar 7 is equipped with two sets of movable wheel assemblies. The movable wheel assembly includes a shaft 17 installed at the bottom of the crossbar 7, and the bottom of the shaft 17 is equipped with a shock-absorbing caster 8 by bolts.

[0026] The top of the shock-absorbing caster 8 is provided with a positioning hole 18, and the top of the crossbar 7 is provided with four sets of fixing members 9. The fixing members 9 are located inside the positioning hole 18 and are used to limit the direction of the moving wheel assembly.

[0027] The height adjustment lever 6 is welded to the top of the crossbar 7, and two sets of axles 17 are welded to the bottom of the crossbar 7. The shock-absorbing casters 8 are fixed to the bottom of the axles 17 by bolts. The shock-absorbing casters 8 use internal springs and dampers to buffer and absorb vibrations and impacts from the road surface. When the mini-tiller is working in the field, uneven road surfaces cause significant vibrations for the operator, leading to fatigue during prolonged operation. When the mini-tiller travels over uneven surfaces, the springs inside the shock-absorbing casters 8 can compress or extend to absorb the impact force. The impact force is converted into elastic energy, thereby reducing the direct impact on the vehicle and reducing the vibration of the mini-tiller. Since the height of the rear frame is adjustable, it can accommodate operators of different heights and improve the comfort of operation. Under the action of the axle 17, the shock-absorbing caster 8 can rotate in any direction. When it is necessary to travel in a straight line, the fixing part 9 is inserted into the crossbar 7. At this time, the fixing part 9 will be embedded in the positioning hole 18, fixing the direction of the shock-absorbing caster 8, so that the mini-tiller can travel in a straight line better, thereby improving the working efficiency of the mini-tiller to a certain extent.

[0028] A protective pad 15 is installed inside the square groove. The protective pad 15 is located outside the height adjustment rod 6. Mounting holes 16 are provided through both sides of the fixing frame 3. The mounting holes 16 correspond to the positions of the fixing plug 11.

[0029] The height adjustment rod 6 has mounting holes 10 evenly arranged inside, and the positions of mounting holes 10 and mounting holes 16 are corresponding to those of mounting holes 16.

[0030] One end of the fixing plug 11 is provided with a mounting hole 3 14, which corresponds to the position of the pin 13.

[0031] The fixing plate 5 has a second mounting hole 12 inside, which is used to install the working tool;

[0032] The protective pad 15 provides some protection for the height adjustment rod 6. When adjusting the height of the height adjustment rod 6, it will not cause serious damage due to long-term mutual friction between the height adjustment rod 6 and the fixing frame 3, thus affecting the service life of the height adjustment rod 6 and the fixing frame 3. In addition, the inner surface of the protective pad 15 has a waterproof coating, which reduces the time that rainwater stays on the protective pad 15. On rainy days, the rainwater on the surface of the protective pad 15 will slide off quickly, reducing the occurrence of corrosion due to direct contact between the fixing frame 3 and the height adjustment rod 6. The height adjustment rod 6 and the fixing frame 3 can be fixed by inserting the pin 13 into the mounting hole 14. The multiple sets of mounting holes 10 make it easy to adjust the relative extension length of the height adjustment rod 6 and the fixing frame 3.

[0033] Working principle: First, use bolts to fix the mounting plate 1 to the corresponding position on the mini tiller. Then, push the height adjustment rod 6 vertically into the square groove from below the fixing frame 3. Adjust the height adjustment rod 6 to an appropriate height according to the actual height of the mini tiller, the tools to be installed later, and the user's needs, so that the mounting hole 4 16 is aligned with the mounting hole 10. Next, insert the fixing plug 11 into it, and then insert the pin 13 into the mounting hole 3 14 to fix the height adjustment rod 6 and the fixing frame 3. Finally, fix the required tools between the two sets of fixing plates 5 with bolts.
