[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Protective sleeves 6, multiple sets of protective sleeves 6 are detachably mounted on the end surface of the tilling plate 5;

[0035] The protective mechanism is arranged between the protective sleeve 6 and the tilling plate 5. After the protective sleeve 6 is installed between the tilling plate 5, when the tilling plate 5 contacts the soil for tilling, the connection between the protective sleeve 6 and the tilling plate 5 is passively fixed, and the expansion plate 7 at the end of the protective sleeve 6 is passively expanded to increase the area of ​​the tilled soil, and passively vibrates while the expansion plate 7 is expanding.

[0036] In another embodiment of the present invention, preferably, when the protective cover 6 and the tilling plate 5 are fixedly assembled, the end surface of the extrusion plate 12 contacts the bottom end surface of the installation groove 9.

[0037] In another embodiment provided by the present invention, preferably, a transmission shaft 3 connected to the motor is provided in the tiller 1, and a plurality of groups of mounting plates 4 are evenly spaced and installed on the surface of the transmission shaft 3 by bolts, and a plurality of groups of tilling plates 5 are installed on all four sides of each group of mounting plates 4 by bolts.

[0038] In another embodiment provided by the present invention, a connecting arm 2 for connecting to a power machine is installed on the top of the tiller 1.

[0039] In another embodiment provided by the present invention, the protective mechanism includes a plurality of connecting rods 8 arranged on the end surface of the tilling plate 5, the top end of the connecting rod 8 is detachably inserted in the mounting groove 9, the mounting groove 9 is correspondingly opened on the inner side of the protective sleeve 6, the top end of the connecting rod 8 is movably inserted with a telescopic rod 15 through a reset spring 16, the top end of the telescopic rod 15 passes through the outside of the top end of the connecting rod 8 and is fixedly connected to the extrusion plate 12, an expandable and contractible limiting ring 13 is arranged between the extrusion plate 12 and the top end of the connecting rod 8, the limiting ring 13 is detachably inserted in the limiting groove 11, and the limiting groove 11 is correspondingly opened on the inner side wall of the mounting groove 9.

[0040] In another embodiment provided by the present invention, a contact ring 14 is fixedly connected to the outer side of the bottom end of the connecting rod 8, and the two sides of the contact ring 14 slide and contact the surface of the vibration plate 10 set on the inner wall of the expansion plate 7, and the expansion plate 7 is movably installed on both sides of the protective cover 6 facing the plowing plate 5.

[0041] In yet another embodiment provided by the present invention, the outer diameter of the limiting ring 13 in a completely relaxed state is greater than the inner diameter of the mounting groove 9 .

[0042] In another embodiment provided by the present invention, the outer diameter of the limiting ring 13 is smaller than the inner diameter of the limiting groove 11 when it is in an expanded state due to the extrusion limit.

[0043] In another embodiment provided by the present invention, the surface of the vibrating plate 10 is provided with multiple sets of tooth-shaped structures, and each set of teeth has a right-angled triangular cross-section.

[0044] When the land needs to be plowed, after installing the protective sleeves 6 on the end faces of the plowing plates 5, the plowing machine 1 is installed on the power machinery through the connecting arm 2. The power machinery drives the plowing machine 1 to move on the land, and the plowing plates 5 installed in the plowing machine 1 rotate along with the transmission shaft 3 of the connecting motor, so as to plow the land.

[0045] The motor in the plowing machine 1 drives the transmission shaft 3 to rotate clockwise, so that multiple sets of plowing plates 5 fixedly installed at equal intervals on the transmission shaft 3 rotate clockwise accordingly, so as to turn over the land. However, during the rotation process of the plowing plates 5, the protective sleeves 6 and the expansion plates 7 installed on the side of the plowing plates 5 that first contact the soil protect the end faces of the plowing plates 5.

[0046] After the protective sleeve 6 contacts the soil, it is blocked by the soil and moves closer to the end face of the plowing plate 5. During the process of the protective sleeve 6 fitting to the plowing plate 5, the connecting rod 8 inserted into the installation groove 9 opened on the inner side of the protective sleeve 6 continues to be inserted inward, so as to use the bottom end of the installation groove 9 to squeeze the extrusion disc 12, thereby squeezing the extrusion disc 12 inward against the telescopic rod 15 and the return spring 16. At the same time that the extrusion disc 12 is inserted into the connecting rod 8, the outer periphery of the limiting ring 13 provided between the extrusion disc 12 and the connecting rod 8 expands outward and is inserted into the limiting groove 11, so as to better mutually limit between the protective sleeve 6 and the plowing plate 5.

[0047] During the process of the protective sleeve 6 moving closer to the end face of the plowing plate 5, the contact ring 14 provided at the bottom end of the connecting rod 8 will contact the expansion plates 7 rotatably installed on both sides of the end of the protective sleeve 6, so that the expansion plates 7 are squeezed by the contact ring 14 and expand to both sides, thereby increasing the range of soil plowed by each plowing plate 5.

[0048] At the same time, when the contact ring 14 contacts the expansion plate 7, it slides on the surface of the vibrating plate 10 provided on the inner side wall of the expansion plate 7. Through the sliding contact between the stepped teeth provided on the surface of the vibrating plate 10 and the contact ring 14, the vibrating plate 10 vibrates while expanding, providing an auxiliary force for the expansion of the expansion plate 7 and being able to shake off the soil adhering to the expansion plate 7.

[0049] After the corresponding plowing plate 5 rotates to separate from the soil, the return spring 16 rebounds and pushes the extrusion disc 12 outward a certain distance through the telescopic rod 15. At this time, the depth of the limiting ring 13 inserted into the limiting groove 11 is reduced, but the limiting ring 13 is not completely pulled out of the limiting groove 11, which can realize the connection between the protective sleeve 6 and the end face of the plowing plate 5.

[0050] The outer diameter of the limiting ring 13 is greater than the inner diameter of the mounting groove 9 in the fully relaxed state. When installing between the protective sleeve 6 and the ploughshare 5, the connecting rod 8 is inserted into the mounting groove 9. The friction between the limiting ring 13 and the inner side wall of the mounting groove 9 can also provide a certain limiting effect on the connection of the protective sleeve 6. And after the connecting rod 8 is inserted into the mounting groove 9 until the limiting ring 13 reaches the position of the limiting groove 11, at this time, the force required to insert the connecting rod 8 inward will be significantly reduced, and the installation of the protective sleeve 6 is completed. When the protective sleeve 6 contacts the obstruction of the soil, the limiting ring 13 will be expanded outward to better fix and install between the protective sleeve 6 and the ploughshare 5;

[0051] The surface of the vibrating plate 10 is provided with multiple groups of tooth-shaped structures, and each group of teeth has a cross-section in the shape of a right-angled triangle. When the protective sleeve 6 contacts the soil and approaches the ploughshare 5, the short side of the right angle faces the moving direction of the abutting ring 14. When the protective sleeve 6 receives the resistance of the soil, it can provide greater power for the abutting ring 14 to slide from one short side of the right angle to the front short side on the surface of the vibrating plate 10. And after the separation between the protective sleeve 6 and the soil, when the return spring 16 rebounds to separate the protective sleeve 6 and the ploughshare 5, the abutting ring 14 only needs a small force to slide along the inclined surface of the teeth inside the vibrating plate 10;

[0052] By setting the protective sleeve 6, it can provide protection for the ploughshare 5 when the ploughshare 5 ploughs the land, and can provide a certain buffering force for the position of the ploughshare 5, preventing the ploughshare 5 fixed by bolts from loosening due to the frequent contact and resistance of the soil during long-term rotation. The protective sleeve 6 can pre-contact the soil to provide a certain buffering protection. At the same time, through the expansion plates 7 arranged on both sides of the protective sleeve 6, when ploughing the soil, the contact area between the ploughshare 5 and the soil can be increased to improve the ploughing effect on the soil. And the vibrating expansion plates 7 can also vibrate while ploughing the soil, better using the ploughshare 5 to plough the soil, and can also vibrate and clean the soil attached to the surface of the protective sleeve 6. Moreover, the installation and disassembly of the protective sleeve 6 only rely on inserting the connecting rod 8 into the mounting groove 9, and there is an obvious reminder when the installation is in place, which is convenient for the installation and disassembly of the protective sleeve 6.

[0053] Device structure composition:

[0054] The tiller 1 is provided with a transmission shaft 3 connected to a motor. Multiple mounting discs 4 are evenly spaced and fixed on the surface of the transmission shaft 3 by bolts. Multiple tilling plates 5 are installed around each mounting disc 4 by bolts; a connecting arm 2 is installed at the top of the tiller 1 for connecting to a power machine. The multiple tilling plates 5, as the components directly tilling the ground, are detachably installed with multiple protective sleeves 6 at their end faces. A protection mechanism is arranged between the protective sleeve 6 and the tilling plate 5, and the specific structure is as follows: Multiple connecting rods 8 are provided on the end face of the tilling plate 5, and their tops can be inserted into the corresponding installation grooves 9 opened inside the protective sleeve 6; an expansion rod 15 is movably inserted into the inner top end of the connecting rod 8 through a return spring 16, and the top end of the expansion rod 15 extends out of the connecting rod 8 and is fixedly connected to a pressing disc 12; a limit ring 13 that can expand and contract is arranged between the pressing disc 12 and the top end of the connecting rod 8, and the limit ring 13 can be inserted into a limit groove 11 opened on the inner side wall of the installation groove 9; a contact ring 14 is fixedly connected to the outer side of the bottom end of the connecting rod 8, and the two sides of the contact ring 14 are slidably in contact with the surfaces of vibration plates 10 arranged on the inner side walls of expansion plates 7 movably installed on both sides of one end of the protective sleeve 6 facing the tilling plate 5. The surfaces of the vibration plates 10 are in the shape of multiple teeth with a right triangle cross-section.

[0055] Installation process of the protective sleeve 6:

[0056] When installing the protective sleeve 6, insert the connecting rod 8 on the end face of the tilling plate 5 into the corresponding installation groove 9 inside the protective sleeve 6. Since the outer diameter of the limit ring 13 is larger than the inner diameter of the installation groove 9 in the fully relaxed state, friction is generated between the limit ring 13 and the inner side wall of the installation groove 9 during the insertion process to provide preliminary positioning. When the connecting rod 8 is inserted until the limit ring 13 reaches the position of the limit groove 11, the required insertion force significantly becomes smaller. At this time, the end face of the pressing disc 12 contacts the bottom end face inside the installation groove 9, and the installation of the protective sleeve 6 is completed.

[0057] Working process of the device:

[0058] During the land tilling operation, the tiller 1 is installed on the power machine through the connecting arm 2. The power machine drives the tiller 1 to move, and the motor inside the tiller 1 drives the transmission shaft 3 to rotate clockwise, causing the tilling plates 5 to rotate accordingly for tilling. When the tilling plates 5 contact the soil, the protective sleeves 6 and expansion plates 7 installed on their end faces contact the soil first. The protective sleeve 6 is pressed against the end face of the tilling plate 5 due to the soil blockage. The installation groove 9 inside the protective sleeve 6 pushes the connecting rod 8 to be further inserted. The bottom end of the installation groove 9 presses the pressing disc 12, and the pressing disc 12 compresses the expansion rod 15 and the return spring 16. At the same time, the outer circumference of the limit ring 13 expands outward and is inserted into the limit groove 11, realizing the firm connection between the protective sleeve 6 and the tilling plate 5.

[0059] During the process of the protective sleeve 6 fitting onto the ploughshare 5, the contact ring 14 at the bottom end of the connecting rod 8 contacts the expansion plate 7, pushing the expansion plate 7 to expand towards both sides, thereby expanding the ploughing range of the ploughshare 5 on the soil. At the same time, the contact ring 14 slides on the surface of the vibrating plate 10. Since the short right-angle side of the teeth on the surface of the vibrating plate 10 faces the moving direction of the contact ring 14, when the protective sleeve 6 is resisted by the soil, it provides greater power for the contact ring 14 to slide from one short right-angle side to the next short right-angle side, causing the vibrating plate 10 to vibrate when expanding, assisting the expansion plate 7 to expand and shaking off the adhering soil. When the ploughshare 5 flips to separate from the soil, the return spring 16 rebounds, driving the extrusion disc 12 to move outwards by a certain distance through the telescopic rod 15, reducing the insertion depth of the limiting ring 13 in the limiting groove 11, but the limiting ring 13 still remains in the limiting groove 11, maintaining the connection state between the protective sleeve 6 and the ploughshare 5.

[0060] Realization of technical effects:

[0061] Through the above structural design and working mode, the protective sleeve 6 provides protection and buffering for the ploughshare 5 during the ploughing process, avoiding the loosening of the bolts of the ploughshare 5 due to frequent contact with the soil; the expansion plate 7 increases the contact area between the ploughshare 5 and the soil, improving the ploughing effect; the vibration function of the vibrating plate 10 not only assists the expansion plate 7 to expand, but also can clean the soil on the surface of the protective sleeve 6; and the protective sleeve 6 is installed and disassembled by means of simple insertion of the connecting rod 8, and the change in force is obvious when installed in place, which is convenient for actual operation and application.

[0062] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
