[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0024] Example 1
[0025] As attached Figure 1 To be continued Figure 5 As shown, this utility model provides a rotary tiller anti-weed entanglement device, including a rotary tiller body 1. The rotary tiller body 1 includes a side plate 101 and a middle seat 102. The side plate 101 and the middle seat 102 are respectively connected to bearing seats 103. The bearing seats 103 are connected to a cutter roller 104. The rotary tiller body 1 also includes other parts, but they are not related to this device and are existing machinery, so they will not be described in detail. The side plate 101 is connected to a first base plate 2, which provides a base for mounting a first cutting blade 3. The first base plate 2 is connected to the first cutting blade 3. The bearing seat 103 is connected to a second base plate 4, which provides a base for mounting a second cutting blade 5. The second base plate 4 is connected to the second cutting blade 5. Multiple first cutting blades 3 and second cutting blades 5 are provided, occupying a certain space, and playing the role of cutting and isolating weeds to prevent weeds from entangled in the bearing seat 103.
[0026] As can be seen from the above, when the rotary tiller body 1 is working, weeds will be turned out of the soil. The first base plate 2 and the first cutting blade 3 form a support, and the second base plate 4 and the second cutting blade 5 form a support, forming a separate space to isolate the bearing seat 103, ensuring that the heat dissipation of the bearing seat 103 can proceed normally. When the blade roller 104 rotates with the rotary tiller blade, the rotary tiller blade will cause the weeds to roll. The rolled weeds are cut and broken by the first cutting blade 3 and the second cutting blade 5, thereby extending the service life of the bearing seat 103.
[0027] Example 2
[0028] As attached Figure 4 As shown, this embodiment is basically the same as the previous embodiment, except that several first cutting blades 3 are curved triangular plates. The first cutting blades 3 are curved in the forward direction of the rotary tiller body 1. Weeds are guided to the cutter roller 104 along the inclined edge of the first cutting blade 3, thereby moving the weeds away from the bearing seat 103. The first cutting blade 3 is provided with an adapter groove 6. The shape of the adapter groove 6 is adapted to the bearing seat 103. After the first base plate 2 is installed, the adapter groove 6 of the first cutting blade 3 is located next to the bearing seat 103. There is a gap between the bearing seat 103 and the adapter groove 6 to avoid friction between the first cutting blade 3 and the bearing seat 103.
[0029] As attached Figure 5 As shown, specifically, the cross-section of the second cutting blade 5 is "L" shaped, and the second cutting blade 5 has a groove 7. The shape of the groove 7 is adapted to the bearing seat 103. After the second substrate 4 is installed, the groove 7 of the second cutting blade 5 is located next to the bearing seat 103, and there is a gap between the bearing seat 103 and the groove 7 to avoid friction between the second cutting blade 5 and the bearing seat 103.
[0030] As can be seen from the above, the first substrate 2 is fixed on the side plate 101, the adapter groove 6 of the first cutting blade 3 is located next to the bearing seat 103, the second substrate 4 is fixed on the middle seat 102, and the groove 7 of the second cutting blade 5 is located next to the bearing seat 103. When the rotary tiller body 1 is working, the weeds are turned over and guided to the blade roller 104 along the inclined side of the first cutting blade 3, thereby moving the weeds away from the bearing seat 103.
[0031] Example 3
[0032] As attached Figure 2 To be continued Figure 5 As shown, this embodiment is basically the same as the previous embodiment, except that the first substrate 2 and the second substrate 4 are provided with mounting holes 8. Several mounting holes 8 are elliptical. The side plate 101 and the intermediate seat 102 are provided with corresponding fixing holes. The elliptical mounting holes 8 improve adaptability and reduce the installation difficulty when the fixing holes and mounting holes 8 are not aligned, thereby facilitating the fixing of the first substrate 2 and the second substrate 4. The mounting holes 8 are provided with bolts 9. The bolts 9 are screwed into the mounting holes 8 and the fixing holes, thereby fixing the first substrate 2 and the second substrate 4.
[0033] As attached Figure 2 To be continued Figure 3 As shown, specifically, the first substrate 2 and the second substrate 4 are arc-shaped plates, and there is a gap between the inner arc edge of the first substrate 2 and the second substrate 4 and the bearing seat 103.
[0034] As attached Figure 4 To be continued Figure 5 As shown, furthermore, the grass-facing parts of the first cutting blade 3 and the second cutting blade 5 are sharpened to improve the cutting and crushing effect of weeds.
[0035] As can be seen from the above, the bolt 9 is screwed into the mounting hole 8 and the fixing hole, thereby fixing the first base plate 2 onto the side plate 101 and fixing the second base plate 4 onto the intermediate seat 102. When the rotary tiller body 1 is working, weeds will be turned over in the soil. The first cutting blade 3 and the second cutting blade 5 will cut and break the nearby weeds. Some tough weeds will be guided along the inclined edge of the first cutting blade 3 to the cutter roller 104, so that the weeds are away from the bearing seat 103. At the same time, there are multiple first cutting blades 3 and second cutting blades 5, which occupy part of the space and thus isolate the bearing seat 103, ensuring that the heat dissipation of the bearing seat 103 can proceed normally.
