[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] To solve the technical problem of how to adjust the length of the rake teeth, please refer to Figures 1 - 3 , the present embodiment provides the following technical solutions:

[0024] A harrow for fertilizing crops includes rake claws 1 and a rake handle 2. The rake handle 2 is fixedly connected to the rake claws 1 through a rake beam 11. A plurality of telescopic grooves 14 are equidistantly formed in the rake claws 1, and telescopic sleeves 31 are slidably arranged in the telescopic grooves 14.

[0025] Among them, the rake beam 11 protrudes upward, and there is a space between the rake beam 11 and the rake claws 1 for the moving plate 34 to slide.

[0026] The telescopic sleeve 31 is fixedly connected to a moving plate 34 through a connecting rod 33. The moving plate 34 slides on the surface of the rake claws 1, and its bottom end fits the surface of the rake claws 1.

[0027] Adjusting plates 12 are symmetrically welded on the left and right of the rake claws 1. There is a groove for the moving plate 34 to move between the adjusting plates 12 and the rake claws 1. A plurality of adjusting holes 121 are equidistantly formed in the adjusting plates 12. The moving plate 34 is detachably connected with a pin 35 adapted to the adjusting holes 121.

[0028] A sliding groove 13 is formed on the surface of the rake claws 1. A connecting rod 33 is slidably arranged in the sliding groove 13. The length of the sliding groove 13 is less than the width of the rake claws 1. The top end of the connecting rod 33 extends outside the sliding groove 13 and is connected to the moving plate 34, and its bottom end extends into the telescopic groove 14 and is connected to the telescopic sleeve 31.

[0029] Among them, the length of the sliding groove 13 is less than the width of the rake claws 1. The function of such a design is to prevent the connecting rod 33 from sliding out of the sliding groove 13 during sliding, and to improve the stability and firmness of the rake teeth 3 during the adjustment process.

[0030] Specifically, remove the pin 35 on the moving plate 34 and pull it out of the adjusting hole 121 so that the moving plate 34 can move freely. Manually push the moving plate 34. As the moving plate 34 moves, the connecting rod 33 will also slide in the sliding groove 13, and at the same time drive the telescopic sleeve 31 to slide in the telescopic groove 14. The telescopic sleeve 31 then drives the rake teeth 3 to move. Until the moving plate 34 is adjusted to the required position, insert the pin 35 back into the corresponding adjusting hole 121 on the adjusting plate 12 to fix the position of the moving plate 34. Finally, gently shake the rake teeth 3 to ensure that they are stable at the new length and will not loosen, and complete the adjustment of the length of the rake teeth 3.

[0031] To solve the technical problem of how to replace and maintain the rake teeth, please refer to Figure 4 , the present embodiment provides the following technical solutions:

[0032] The telescopic sleeve 31 is detachably installed with rake teeth 3 through an installation groove 36. The rake teeth 3 are fixed to the telescopic sleeve 31 through bolts 32.

[0033] Among them, the part of the telescopic sleeve 31 for fixing the rake teeth 3 extends outside the telescopic groove 14. The purpose of this design is to facilitate the installation and disassembly of the rake teeth 3. The user can directly fix or replace the rake teeth 3 outside the telescopic sleeve 31 without having to reach deep inside the telescopic groove 14 for operation. By exposing the fixing part, it is easier for the user to reach the fixing point.

[0034] Specifically, find the bolt 32 on the telescopic sleeve 31 for fixing the rake teeth 3, and use a suitable tool (such as a wrench) to loosen and remove the bolt 32. Once the bolt 32 is removed, the old rake teeth 3 can be taken out from the installation groove 36 inside the telescopic sleeve 31. Then align the new rake teeth 3 and insert them into the installation groove 36. Before insertion, ensure that the direction and position of the rake teeth 3 are correct. Then pass the bolt 32 through the fixing holes on the rake teeth 3 and the telescopic sleeve 31, and use a tool to tighten the bolt 32 to ensure that the rake teeth 3 are firmly fixed on the telescopic sleeve 31. Finally, gently shake the newly installed rake teeth 3 to ensure its stability and no looseness, thus completing the replacement of the rake teeth 3.

[0035] Working principle: For this harrow for fertilizing crops, when it is necessary to adjust the length of the rake teeth 3, remove the pin 35 on the moving plate 34 and pull it out from the adjustment hole 121 so that the moving plate 34 can move freely. Manually push the moving plate 34. As the moving plate 34 moves, the connecting rod 33 will also slide in the sliding groove 13, and at the same time drive the telescopic sleeve 31 to slide in the telescopic groove 14. The telescopic sleeve 31 then drives the rake teeth 3 to move. Until the moving plate 34 is adjusted to the required position, re-insert the pin 35 into the corresponding adjustment hole 121 on the adjusting plate 12 to fix the position of the moving plate 34. Finally, gently shake the rake teeth 3 to ensure its stability at the new length and no looseness, thus completing the adjustment of the length of the rake teeth 3.
