[0029] The following will refer to the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0031] Reference Figure 1 , Figure 3 and Figure 4 The utility model provides an embodiment: an external micro-tillage machine fender, including a U-shaped bracket 14, a plurality of second threaded rods 13 are fixedly connected to the top of the U-shaped bracket 14, a front baffle 1 is connected to the front side of the top of the U-shaped bracket 14 through the second threaded rods 13, the left and right sides of the top of the U-shaped bracket 14 are connected to the main baffle 2 through the second threaded rods 13, the top of the main baffle 2 is slidably connected to the auxiliary baffle 3, the middle of the auxiliary baffle 3 is provided with a limiting groove 15, and the middle of the top of the main baffle 2 is fixedly connected to the first threaded rod 11.

[0032] Specifically, before using the device, the front baffle 1 is first installed on the top of the U-shaped bracket 14, and then installed together on the micro-tillage machine. After installation and tightening, the main baffle 2 is installed on the left and right sides of the U-shaped bracket 14. The auxiliary baffle 3 can be adjusted to increase the baffle area. During different tillage operations, the increased fender area can better prevent soil from entering the main body of the micro-tillage machine, greatly reducing the possibility of malfunction during machine operation, and also making the work of field workers smoother.

[0033] Reference Figure 2 and Figure 3 The front baffle 1 and the main baffle 2 are both threadedly connected to the second threaded rod 13 through a nut and fixed to the top of the U-shaped bracket 14. The outer wall of the first threaded rod 11 is threadedly connected to the rotating cylinder 12. The top of the rotating cylinder 12 is fixedly connected to the adjusting handle 4. The diameter of the rotating cylinder 12 is greater than the width of the limiting groove 15. The height of the first threaded rod 11 is greater than the depth of the limiting groove 15. The diameter of the first threaded rod 11 is less than the width of the limiting groove 15.

[0034] Specifically, when adjusting the auxiliary baffle 3, first rotate the adjusting handle 4 to make the rotating cylinder 12 move upward so that the auxiliary baffle 3 can slide on the top of the main baffle 2. When the position of the auxiliary baffle 3 is adjusted, then rotate the adjusting handle 4 to make the rotating cylinder 12 rotate downward to press the auxiliary baffle 3 against the bottom end of the main baffle 2. The diameter of the first threaded rod 11 is smaller than the depth of the limiting groove 15, which will not prevent the sliding of the auxiliary baffle 3 and increases the convenience of adjusting the area of the mudguard.

[0035] Refer to Figure 1 and Figure 2 , at the rear ends of the main baffles 2 on both left and right sides, a second bolt hole plate 7 is fixedly connected. Inside the inner walls of the second bolt hole plates 7 on both left and right sides, a connecting rod 10 is slidably installed. Anti-loosening nuts 9 are threadedly installed on the outer walls of the opposite ends of the connecting rod 10. Self-locking nuts 8 are fixedly connected to the opposite inner sides of the connecting rod 10. On both left and right sides of the outer wall of the connecting rod 10 near the inner side of the second bolt hole plate 7, a first bolt hole plate 6 is slidably installed. At the rear ends of two adjacent first bolt hole plates 6 on one side, a rear baffle 5 is fixedly connected in common. The front end of the first bolt hole plate 6 does not contact the rear end of the main baffle 2.

[0036] Specifically, when installing the rear baffle 5, place its position at the rear end of the main baffle 2. Align the holes opened in the first bolt hole plate 6 at the front end of the rear baffle 5 and the second bolt hole plate 7 at the rear end of the main baffle 2. Then, pass the connecting rod 10 through and connect the first bolt hole plate 6 and the second bolt hole plate 7. A self-locking nut 8 and an anti-loosening nut 9 are respectively arranged on the inner sides of the connecting rod 10. The main baffle 2 and the rear baffle 5 are connected through the action of the nuts and the bolt hole plates. When disassembling, loosen the anti-loosening nut 9 and then take out the connecting rod 10 from the first bolt hole plate 6 and the second bolt hole plate 7, and then take out the rear baffle 5 to facilitate cleaning the soil attached to it.

[0037] Working principle: The tillage worker first installs the front baffle 1 and the U-shaped bracket 14 on the micro-tiller, and then installs the main baffle 2 on the U-shaped bracket 14 through bolts and nuts. When different mudguarding environments are required, the adjusting handle 4 can be rotated to make the rotating cylinder 12 rotate upward, so that the auxiliary baffle 3 can slide on the top of the main baffle 2. When the position is appropriate, tighten the adjusting handle 4 to fix the auxiliary baffle 3 on the top of the main baffle 2, so as to achieve the effect of adjusting the mudguarding area of the mudguard. The first bolt hole plate 6 at the front end of the rear baffle 5 and the second bolt hole plate 7 at the rear end of the main baffle 2 are fixed through the self-locking nut 8, the anti-loosening nut 9 and the connecting rod 10, so as to fix the rear baffle 5 at the rear end of the main baffle 2. After the tillage work is completed, each baffle can be disassembled by unscrewing each nut and bolt, which is convenient for cleaning the soil attached to the baffle.
