[0022] 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.
[0023] Please see Figure 1-4 The present invention provides an embodiment of a rotary tiller with a built-in protective structure, including a mounting frame 1, a fixed frame 11 fixedly connected to the right side of the top of the mounting frame 1, a connecting shaft 18 movably connected to the left side of the mounting frames 1, a rotary tiller blade 16 fixedly connected to the outside of the connecting shaft 18, and a protective structure provided at the front end of the mounting frame 1.
[0024] The protective structure includes a protective shell 2, a protective plate 3, and a top plate 6. The protective shell 2 is fixedly connected to the front end of the mounting frame 1. The protective plate 3 is provided inside the front end of the protective shell 2. The top plate 6 is fixedly connected to the top of the protective plate 3. The top of the left and right sides of the protective shell 2 is fixedly connected to the top of the top of the top plate 6. The left and right sides of the bottom of the top plate 6 are fixedly connected to the limit blocks 25. The side of the fixed block 5 near the outside is provided with a pull plate 28. The side of the pull plate 28 near the middle is fixedly connected to a limit rod 29. A spring 27 is fixedly connected between the pull plate 28 and the fixed block 5. Limit grooves 26 are respectively opened on the side of the fixed block 5 and the limit block 25 near the outside.
[0025] The limiting block 25 is embedded inside the fixed block 5, and the limiting rod 29 is embedded inside the limiting groove 26. The limiting block 25 is fixed through the limiting groove 26 and the limiting rod 29. The right side of the top rear end of the protective shell 2 is fixedly connected to the connecting frame 14. The connecting frame 14 is equipped with a servo motor 15. The output end of the servo motor 15 is fixedly connected to the worm gear 19. The front end of the connecting shaft 18 is equipped with a worm wheel 17. The worm wheel 17 and the worm gear 19 cooperate with each other.
[0026] Specifically, such as Figure 1 and Figure 4 As shown, the drive component is located on the left side inside the protective shell 2. The protective shell 2 and the protective plate 3 can shield and protect the drive component, preventing it from being exposed and damaged over a long period of time, thus affecting its service life. When the drive component needs to be inspected, the pull plate 28 is pulled to disengage the limiting rod 29 from the inside of the limiting groove 26, thereby allowing the top plate 6 and the protective plate 3 to lose their fixation. Once the protective plate 3 is no longer fixed, the top plate 6 can be pulled to remove the protective plate 3 from the front end inside the protective shell 2. After removal, it is convenient to inspect the components inside the protective shell 2.
[0027] The left side of the mounting bracket 1 and the protective shell 2 are respectively provided with reserved slots 21. The left side of the protective shell 2 is provided with a mounting plate 4. The rear end of the mounting plate 4 is fixedly connected with a mounting rod 22. The right side of the mounting rod 22 is fixedly connected with a cleaning rod 20. The rear end of the left side of the mounting plate 4 and the front end of the left side of the protective shell 2 are respectively provided with fixing holes 24. Fixing bolts 23 are provided inside the fixing holes 24. The front end of the cleaning rod 20 slides inside the reserved slot 21. The mounting plate 4 is fixed through the fixing holes 24 and the fixing bolts 23.
[0028] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the cleaning rod 20 is installed between the left side of the rotary tiller 16 via the fixing bolt 23 and the fixing hole 24. When the rotary tiller 16 rotates, the cleaning rod 20 can clean the soil or stones between the rotary tiller 16 to prevent soil and stones from getting stuck between the rotary tiller 16 and affecting rotary tillage. When the cleaning rod 20 is not needed, the fixing bolt 23 can be unscrewed from the inside of the fixing hole 24 to remove the cleaning rod 20.
[0029] A water tank 7 is installed on the left side of the top of the mounting bracket 1, and a water pump 9 is installed on the right side of the water tank 7. The output end and the input end of the water pump 9 are respectively fixedly connected to the outlet pipe 10 and the connecting pipe 8. The bottom end of the outlet pipe 10 is fixedly connected to the branch pipe 12, and the bottom end of the branch pipe 12 is fixedly connected to the outlet 13. The connecting pipe 8 passes through the inside of the water tank 7.
[0030] Specifically, such as Figure 1 and Figure 2 As shown, the water pump 9 is started. The water pump 9 draws water from the water tank 7 into the branch pipe 12 through the connecting pipe 8 and the outlet pipe 10. Then the branch pipe 12 is raised to spray water onto the rotary tiller blade 16 and the soil. Spraying water can not only help moisten the soil and make it easier to till, but also reduce the friction of soil particles on the rotary tiller blade 16, thereby extending the service life of the rotary tiller blade 16.
[0031] Working Principle: In use, the drive assembly is located on the left side inside the protective shell 2. The protective shell 2 and protective plate 3 protect the drive assembly, preventing long-term exposure and damage that could affect its lifespan. When maintenance is required, pulling the pull plate 28 disengages the limiting rod 29 from the limiting groove 26, thus releasing the top plate 6 and protective plate 3. With the protective plate 3 released, pulling the top plate 6 allows it to be removed from the front end inside the protective shell 2, facilitating maintenance of the components inside the protective shell 2. After maintenance, the protective plate 3 is reinstalled inside the protective shell 2. The rotary tiller is then installed in a suitable position using the fixing bracket 11. The servo motor 15 is then started, and the servo motor 15... The worm gear 19 and worm wheel 17 drive the connecting shaft 18 and the rotary tiller 16 to rotate, thus making the rotary tiller 16 work. The cleaning rod 20 is installed between the left side of the rotary tiller 16 through the fixing bolt 23 and fixing hole 24. When the rotary tiller 16 rotates, the cleaning rod 20 can clean the soil or stones between the rotary tiller 16 to prevent soil and stones from getting stuck between the rotary tiller 16 and affecting rotary tillage. The water pump 9 is started. The water pump 9 draws water from the water tank 7 into the branch pipe 12 through the connecting pipe 8 and the outlet pipe 10. Then the branch pipe 12 is raised to spray water onto the rotary tiller 16 and the soil. Spraying water can not only help to moisten the soil and make it easier to till, but also reduce the friction of soil particles on the rotary tiller 16, thereby extending the service life of the rotary tiller 16.
[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
