In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0029] Refer to Figure 1 - Figure 4As shown in the figure, the utility model provides a technical solution: a weeding machine, which includes a working push rod 1. One end of the arc surface of the working push rod 1 is installed with a power device 4. The inside of the power device 4 is installed with a driving shaft. Both ends of the arc surface of the driving shaft are installed with adjusting output rollers 5. A number of weeding blades 6 are installed on the arc surfaces of the adjusting output rollers 5. A support mechanism 2 is provided on the arc surface of the working push rod 1, and an auxiliary fixing mechanism 3 is provided on the arc surface of the working push rod 1 close to the power device 4.

[0030] Next, specifically describe the specific settings and functions of its adjusting device and auxiliary device.

[0031] Refer to Figure 2 and Figure 3As shown in the figure, in this embodiment: The support mechanism 2 includes two mounting blocks 201, both of the two mounting blocks 201 are slidably connected to the arc surface of the working push rod 1. On one side of the two mounting blocks 201 close to each other, two blocking rods 202 are fixedly connected respectively. On the side of the mounting block 201 close to the power device 4, a bottom fixing rod 203 is fixedly connected. At one end of the two mounting blocks 201, there is a same mounting plate 204. At both ends of the side of the mounting plate 204 close to the bottom fixing rod 203, jacks 205 are opened, and the two jacks 205 are respectively slidably connected to the two bottom fixing rods 203. A rotating adjustment rod 206 is threadedly penetrated through the inner wall of the mounting plate 204. At one end of the arc surface of the rotating adjustment rod 206 close to the working push rod 1, a contact piece 207 is fixedly connected. At one end of the arc surface of the rotating adjustment rod 206 far from the contact piece 207, an adjustment block 208 is fixedly connected. At one end of the two mounting blocks 201 far from the mounting plate 204, a same rotating shaft 209 is fixedly connected. An adjustment support rod 210 is movably connected to the arc surface of the rotating shaft 209. On one side of the adjustment support rod 210, a butting plate 211 is fixedly connected. At both ends of the arc surface of the rotating shaft 209, coil springs 212 are sleeved. The two ends of the coil spring 212 are respectively fixedly connected to the rotating shaft 209 and the adjustment support rod 210. At one end of the arc surface of the rotating shaft 209, a limiting piece 216 is fixedly connected. Through the working push rod 1, the adjustment output roller 5 can be driven to roll on the ground. The power device 4 drives the adjustment output roller 5 to roll through the driving shaft installed inside. When the adjustment output roller 5 moves, the weeding blades 6 can be driven to perform weeding work. However, when the whole weeding machine is not in use, the working push rod 1 of the weeding machine will come into contact with the ground. If the working push rod 1 of the weeding machine comes into contact with the ground for a long time, wear will occur. The worn working push rod 1 has a poor use experience during use, and at the same time, its service life will be greatly reduced. At this time, when the working push rod 1 of the weeding machine is not in use, the rod body of the working push rod 1 can be supported by the adjustment device, so as to avoid the direct contact between the working push rod 1 and the ground through the support, and avoid wear of the working push rod 1. At the arc surface end of the bottom fixing rod 203 far from the mounting block 201, a guiding block 213 is fixedly connected. The cross section of the guiding block 213 is arc-shaped. When the bottom fixing rod 203 is connected to the jack 205, the guiding block 213 installed on the bottom fixing rod 203 can improve the connection speed between the bottom fixing rod 203 and the inner wall of the jack 205, so that the connection efficiency of the two can be improved through the guiding block 213. On the arc surface of the adjustment block 208, a number of anti-slip grooves 214 are opened. The number of anti-slip grooves 214 is evenly distributed on the arc surface of the adjustment block 208. When the adjustment rod 206 is rotated through the adjustment block 208, the anti-slip grooves 214 opened on the adjustment block 208 can increase the friction between the hand of the user and the adjustment block 208, so that the speed at which the user rotates the adjustment rod 206 through the adjustment block 208 can be increased through the anti-slip grooves 214. The four blocking rods 202 are grouped in pairs.One end of the arc surface of the working push rod 1 is provided with a contact groove 215 corresponding to the position of each set of assembly rods. When the blocking rod 202 comes into contact with the surface of the working push rod 1, the contact groove 215 provided at the position of the working push rod 1 corresponding to the blocking rod 202 can improve the stability when the blocking rod 202 contacts the working push rod 1, thereby improving the connection effect when the two are connected.

[0032] Referring to Figure 4 As shown, in this embodiment: The auxiliary fixing mechanism 3 includes a fixing ring 31, the fixing ring 31 is fixedly connected to the arc surface of the working push rod 1, one end of the arc surface of the fixing ring 31 is fixedly connected with a connecting frame 32, a positioning rod 33 slides through the inner wall of the connecting frame 32, a spring 34 is sleeved on the arc surface of the positioning rod 33, and both ends of the spring 34 are fixedly connected to the connecting frame 32 and the positioning rod 33 respectively. The adjusting support rod 210 is provided with a positioning hole 35 corresponding to the position of the positioning rod 33. When the support frame mechanism is not used to support the working push rod 1, the auxiliary fixing mechanism 3 can be used to further fix the rod position of the adjusting support rod 210 of the support mechanism 2, so that the auxiliary fixing mechanism 3 can be used to improve the stability of the overall placement when the support mechanism 2 is not in use. One end of the arc surface of the positioning rod 33 is fixedly connected with a pull ring 36. When it is necessary to pull the spring 34 through the positioning rod 33, the pull ring 36 installed on the positioning rod 33 can be used to pull the positioning rod 33. The pull ring 36 can improve the speed and efficiency of pulling the positioning rod 33. The positioning rod 33 is a titanium alloy rod. The rod body of the positioning rod 33 made of titanium alloy is relatively hard. After long-term use, the rod body of the positioning rod 33 is also difficult to deform. The service life and use effect of the positioning rod 33 made of titanium alloy are both good.

[0033] Detailed description of the usage method: When it is necessary to support the working push rod 1, place the two mounting blocks 201 on one side of the working push rod 1. At this time, the jack 205 opened on the mounting plate 204 can be connected to the bottom fixing rod 203. At this time, the adjusting block 208 can be used to rotate the adjusting rod 206 in the inner wall of the mounting plate 204, and the contact piece 207 can be driven to contact the working push rod 1 by rotating the adjusting rod 206, so that the mounting block 201 can be fixed on the working push rod 1. At this time, the adjusting support rod 210 can be pulled. The movement of the adjusting support rod 210 will rotate on the rotating shaft 209 and drive the coil spring 212 to stretch. The limiting piece 216 can limit the adjusting angle of the adjusting support rod 210. At this time, the abutting plate 211 is brought into contact with the ground, and the entire working push rod 1 can be supported by the contact between the abutting plate 211 and the ground.

[0034] When it is necessary to fix the adjusting support rod 210 on the support mechanism 2, pull the positioning rod 33 away from the adjusting support rod 210. The movement of the positioning rod 33 will drive the spring 34 to stretch. At this time, the rod body angle of the adjusting support rod 210 on the rotating shaft 209 can be adjusted, and the adjusted adjusting support rod 210 can be connected to the inside of the connecting frame 32. Then, release the positioning rod 33. The reset of the spring 34 will drive the positioning rod 33 to connect with the positioning hole 35 opened on the adjusting support rod 210, and the angle of the adjusting support rod 210 can be fixed.
