DETAILED DESCRIPTION

[0027] The following will be combined with 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 in 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.

[0028] The utility model provides Figure 1 The agricultural machinery lifting and adjusting device shown comprises:

[0029] The frame 1 has a soil-raising knife 12 and an extension seat 11 installed at the bottom end of the frame 1, and an adjusting member 13 for driving the extension seat 11 to rise and fall is installed at the top end of the frame 1; and a roller is installed at the bottom of the extension seat 11; wherein, the structures and principles of the adjusting member 13, the extension seat 11 and the frame 1 are all prior arts, and specific reference is made to the comparative document (a Chinese patent with authorization announcement number CN216362469U discloses a frame height adjustment device for an agricultural machine), which will not be repeated here.

[0030] As can be seen from the above, when in use, the horizontal distance between the roller and the frame 1 is adjusted by driving the adjusting component 13. When the roller under the frame 1 contacts the soil, the depth of the soil-raising knife 12 cutting into the soil can be controlled by adjusting the component 13, so that the soil-raising knife 12 can fully turn over the soil.

[0031] refer to Figure 1-Figure 4 As shown, the protective component 2 is used to protect the adjusting component 13. The protective component 2 includes a shell 21 installed on the top of the frame 1 and a cavity 22 opened at the bottom of the shell 21 for inserting the adjusting component 13. The top of the frame 1 is provided with a positioning component connecting it with the shell 21, and the positioning component is provided with a cleaning component 3 for cleaning the outside of the soil knife 12.

[0032] The positioning assembly includes a positioning slot 24 opened at the top of the frame 1 and a positioning plate 23 fixed at the bottom of the shell 21, and the positioning plate 23 is plugged and fixed to the positioning slot 24; a threaded hole 26 is opened on one side of the frame 1 and the positioning plate 23, and a threaded column 25 is screwed into the threaded hole 26.

[0033] Through the above technical solution:

[0034] When used in a rainy environment, by covering the shell 21 on the adjusting member 13, the positioning plate 23 and the positioning groove 24 correspond to each other, the shell 21 is slowly moved close to the outside of the adjusting member 13, and the positioning plate 23 is inserted into the positioning groove 24, so that the threaded hole 26 opened on the positioning plate 23 and the threaded hole 26 opened on the frame 1 are kept coincident, and the cavity 22 covers the adjusting member 13, and then the adjusting member 13 is closed in the cavity 22 opened at the bottom of the shell 21 to avoid it being exposed to the outside world, thereby ensuring the normal use of the adjusting member 13, and then the threaded column 25 is screwed into the threaded hole 26, and the positioning plate 23 and the positioning groove 24 are screwed and fixed, so as to achieve a stable connection between the shell 21 and the frame 1, and improve the stability of the adjusting member 13.

[0035] In addition, refer to Figure 1-Figure 5 As shown, the cleaning component 3 includes a mounting frame 31 mounted on the soil-raising knife 12 and a guide groove 32 provided on the bottom wall of the positioning groove 24, and the top of the mounting frame 31 extends into the guide groove 32 and is fixed to the bottom end of the positioning plate 23, and a cleaning cavity 33 is provided at the bottom end of the mounting frame 31 for the soil-raising knife 12 to slide into, an inclined cleaning scraper 34 is installed in the cleaning cavity 33, and one side of the cleaning scraper 34 is in contact with one side of the soil-raising knife 12, and a fine-tuning component 4 is provided in the cleaning cavity 33 for driving the cleaning scraper 34 to move; the fine-tuning component 4 includes a connecting column 41 fixed to one side of the cleaning scraper 34 and an extension groove 42 provided in the cleaning cavity 33 for the connecting column 41 to be inserted, a plurality of latch grooves 43 are provided on the outside of the connecting column 41, a slot communicating with the inside of the connecting column 41 is provided on one side of the mounting frame 31, a latch column 44 is inserted on the mounting frame 31, and the latch column 44 is inserted into the latch groove 43 corresponding to the latch through the slot.

[0036] Through the above technical solution:

[0037] When the positioning plate 23 is inserted into the positioning groove 24, one end of the mounting frame 31 passes through the guide groove 32 and moves to the outside of the ridging knife 12. At this time, the inside of the cleaning cavity 33 is sleeved on the outside of the ridging knife 12, and there is a distance between them. When the outside of the ridging knife 12 is located in the cleaning cavity 33, one side of the cleaning scraper 34 is in contact with the outside of the ridging knife 12, and then the ridging knife 12 rotates and slides along the inside of the cleaning cavity 33, and then the cleaning scraper 34 scrapes the soil carried by the outside of the ridging knife 12. After the ridging knife 12 rotates and disengages from the cleaning cavity 33, the amount of soil carried on its surface will be reduced, and the soil carried by the outside of the ridging knife 12 can be scraped and cleaned, which is beneficial for the ridging knife 12 to be able to cut the soil more effectively, improve the working efficiency, and extend the service life of the ridging knife 12;

[0038] At the same time, the cleaning scraper 34 can be adjusted according to needs through the fine-tuning component 4. At this time, the pin column 44 is pulled to slide along the slot, and then one end of the pin column 44 is disengaged from one of the pin slots 43, so that the connecting column 41 loses its limiting function in the extension slot 42, and the cleaning scraper 34 is pushed to drive the connecting column 41 to move along the extension slot 42, and the pin column 44 is pushed again to insert it into another pin slot 43, so that the distance between the cleaning scraper 34 and the soil knife 12 can be fine-tuned, so that the cleaning scraper 34 and the soil knife 12 maintain a good fit.

[0039] Furthermore, a slide groove 45 is provided in the slot, and a retaining ring 46 is sleeved on the outside of the latch column 44, and a spring 47 is connected between the retaining ring 46 and the slide groove 45; based on this, when the latch column 44 slides outward along the slot, the retaining ring 46 slides along the slide groove 45 to cause the spring 47 to be compressed between the retaining ring 46 and the slide groove 45, and the cleaning scraper 34 is pulled to check whether the connecting column 41 can slide in the extension groove 42. When the connecting column 41 slides along the extension groove 42, the pull on the latch column 44 is loosened, and the elastic force of the spring 47 pushes the retaining ring 46 to move along the slide groove 45, and then the retaining ring 46 moves to drive The latch column 44 is in conflict with the outside of the connecting column 41, and then one end of the latch column 44 is located between the two latch grooves 43. Under the movement of the connecting column 41, one of the latch grooves 43 is supported and overlapped with the latch column 44, and the latch column 44 and the latch groove 43 are plugged together. After the latch column 44 is inserted into the inside of the latch groove 43, there is a conflict between the retaining ring 46 and the slide groove 45, and the spring 47 is located between the retaining ring 46 and the slide groove 45 and stretches, and then a reaction force can be generated on the latch column 44, which can prevent the latch column 44 from being stretched at will, thereby ensuring a good fit between the latch column 44 and the latch groove 43.

[0040] Furthermore, one end of the latch post 44 extends to the outside of the slot and is fixed with a pull disk, and the diameter of the pull disk is larger than the slot. Based on this, the pull disk can have a larger force-bearing area with the user's hand, so that the user can hold it and apply force more easily, so as to facilitate pulling or pushing the latch post 44, thereby achieving the purpose of speeding up the assembly or disassembly operation.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
