[0051] In the initial state, the rotary tiller is placed on the top of the thin plate, in contact with the rubber head and with a certain degree of extrusion; when the rotary tiller enters the soil, the soil gives the rotary tiller a resistance so that the rotary tiller pushes the fan-shaped block to drive the first trapezoidal slider to move in the direction of the second trapezoidal slider. Since the inclined sides of the first trapezoidal slider and the second trapezoidal slider are in contact with each other and can produce relative sliding through extrusion, the second trapezoidal slider is squeezed to move toward the return spring, so that the return spring is squeezed; when the rotary tiller leaves the soil, the resistance of the soil to the rotary tiller disappears, the return spring is reset, and the rubber head on the second trapezoidal slider bounces back to its original position and collides with the rotary tiller, thereby providing an axial force (in a direction parallel to the axis of the cutter disc main body, the same below) to the rotary tiller. In addition, when the rotary tiller is subjected to axial force, the rotary tiller vibrates axially, and the soil attached to the rotary tiller falls off through axial vibration; at the same time, at the moment the rotary tiller leaves the soil, the fan-shaped block is reset to provide the rotary tiller with A lateral force (in a direction parallel to the surface of the cutter disc, the same below) causes the rotary tiller to shake laterally and collide with the rubber pads on the inner walls of both sides of the limit frame, thereby giving the rotary tiller a lateral vibration, causing the soil attached to the rotary tiller to fall off; by utilizing the resistance difference when the rotary tiller enters the soil and leaves the soil, the device can produce a dual lateral and axial vibration effect, thereby vibrating the soil on the rotary tiller to fall off, thereby achieving the effect of clearing the soil attached to the rotary tiller; in addition, through the clearance fit between the rotary tiller and the rotary tiller fixed shaft, the rotary tiller can produce a larger shaking, and without affecting the normal use of the rotary tiller, it can provide the rotary tiller with a larger shaking space, thereby improving the lateral and axial vibration effects; by adding an adjustment mechanism, a preset thrust or pull can be provided to the axial vibration generating mechanism, so that the device can maintain a stable vibration effect under different soil types and humidity conditions, thereby improving the flexibility of the device.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0071] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and therefore the scope of protection of the present application is not limited by the specific embodiments disclosed below.

[0072] The following refers to Figures 1 to 9 A rotary tiller, a rotary tiller assembly and a rotary tiller are described according to some embodiments of the present application.

[0073] Embodiment one

[0074] A rotary tiller, comprising a tiller body 1, a plurality of rotary tiller fixing shafts 2, a plurality of limiting racks 3 and a plurality of axial vibration generating mechanisms 4; wherein the plurality of rotary tiller fixing shafts 2 are arranged in a circle on the surface of the tiller body 1; each rotary tiller fixing shaft 2 is used to assemble a rotary tiller 6, and the rotary tiller 6 is rotatably connected with the rotary tiller fixing shaft 2 in a clearance fit; the plurality of limiting racks 3 are arranged on the surface of the tiller body 1 one by one corresponding to the plurality of rotary tiller fixing shafts 2, and each limiting rack 3 is located on the side of the corresponding rotary tiller fixing shaft 2 away from the center of the tiller body 1; the limiting rack 3 is used to limit the rotation angle of the corresponding rotary tiller 6; the plurality of axial vibration generating mechanisms 4 are arranged on the surface of the tiller body 1 one by one corresponding to the plurality of limiting racks 3, and each axial vibration generating mechanism 4 is located on the side of the corresponding limiting rack 3 away from the corresponding rotary tiller fixing shaft 2; each axial vibration generating mechanism 4 can be in contact with the corresponding rotary tiller 6, and is used to apply an axial force to the rotary tiller 6 to make it vibrate axially.

[0075] It should be noted that the tiller body 1 is a cylinder, and a mounting hole adapted to the tiller mounting shaft of the rotary tiller is arranged in the middle thereof; the distance between any two adjacent rotary tiller mounting shafts 2 is equal; each rotary tiller mounting shaft 2, its corresponding limiting rack 3 and axial vibration generating mechanism 4 are arranged in turn laterally outward along the tiller body 1, the rotary tiller mounting shaft 2 is arranged at a position close to the center of the tiller body 1, the axial vibration generating mechanism 4 is arranged at a position away from the center of the tiller body 1, and the limiting rack 3 is arranged between the corresponding rotary tiller mounting shaft 2 and the axial vibration generating mechanism 4.

[0076] Further, the mounting end of the rotary tiller 6 is inserted into the cavity of the limiting frame 3 from the end of the limiting frame 3 close to the axial vibration generating mechanism 4 to the rotary tiller fixing shaft 2, the rotary tiller 6 is installed on the rotary tiller fixing shaft 2, so that the rotary tiller 6 is rotationally connected with the rotary tiller fixing shaft 2 and is in clearance fit; the cutter head main body 1 is installed on the rotary tiller shaft, when the rotary tiller 6 enters the soil, the soil gives the rotary tiller 6 a resistance, the rotary tiller 6 gives the axial vibration generating mechanism 4 a transverse extrusion by using the resistance given by the soil, through the internal structure of the axial vibration generating mechanism 4, the rotary tiller 6 gives itself an axial extrusion, when the rotary tiller 6 leaves the soil, the resistance given by the soil to the rotary tiller 6 disappears, the transverse and axial extrusions given by the rotary tiller 6 to the axial vibration generating mechanism 4 disappear, at this time, the axial vibration generating mechanism 4 resets the rotary tiller 6 to an axial (in the direction parallel to the axis of the cutter head main body 1, the same below) elastic force, so that the rotary tiller 6 generates axial vibration, at the same time, when the axial vibration generating mechanism 4 resets, the rotary tiller 6 can also be pushed transversely (in the direction parallel to the surface of the cutter head main body 1, the same below), so that the rotary tiller 6 collides with the inner wall of the limiting frame 3, thereby generating transverse vibration; through the cooperation of the axial vibration generating mechanism 4 and the limiting frame 3, the rotary tiller 6 can generate double axial and transverse vibrations when leaving the soil, thereby increasing the removal effect of the device on the soil attached to the rotary tiller 6.

[0077] It should be noted that the axial vibration generating mechanism 4 includes an L-shaped slide rail 41, a first sliding block assembly 42, a second sliding block assembly 43 and a reset spring 44; wherein the L-shaped slide rail 41 includes a horizontal part 411 and a vertical part 412 connected with each other at one end, the horizontal part 411 is connected with the surface of the cutter head main body 1; the first sliding block assembly 42 is slidingly arranged on the horizontal part 411, the first sliding block assembly 42 can slide horizontally in the L-shaped slide rail 41; the second sliding block assembly 43 is slidingly arranged on the vertical part 412 close to the horizontal part 411, the second sliding block assembly 43 can slide vertically in the L-shaped slide rail 41, the second sliding block assembly 43 is in contact with the first sliding block assembly 42 and can generate relative sliding by extrusion; the reset spring 44 is arranged between the horizontal part 411 and the second sliding block assembly 43, one end of the reset spring 44 is connected with the top of the horizontal part 411, the other end is connected with the bottom of the second sliding block assembly 43.

[0078] Further, the action process of the rotary blade 6 on the axial vibration mechanism 4 is as follows: initially, the top of the second sliding block assembly 43 is in contact with the rotary blade 6; when the rotary blade 6 enters the soil, the first sliding block assembly 42 located on the horizontal part 411 of the L-shaped sliding rail 41 is subjected to the pushing force of the rotary blade 6, thereby sliding along the horizontal part 411 of the L-shaped sliding rail 41 to the vertical part 412, extruding the second sliding block assembly 43; the second sliding block assembly 43 is in sliding connection with the vertical part 412, so that when the first sliding block assembly 42 slides, extrusion is formed through the contact surface between the first sliding block assembly 42 and the second sliding block assembly 43, thereby pushing the second sliding block assembly 43 to slide downward and extruding the reset spring 44, so that the second sliding block assembly 43 is separated from the rotary blade 6; when the rotary blade 6 leaves the soil, the resistance of the soil to the rotary blade 6 gradually disappears, at this time, the extrusion of the rotary blade 6 to the first sliding block assembly 42 disappears, at this time, the reset spring 44 resets, driving the second sliding block assembly 43 and the first sliding block assembly 42 to reset; when the second sliding block assembly 43 resets, the second sliding block assembly 43 re-contacts the rotary blade 6 and provides an axial vibration force to the rotary blade, so that the rotary blade is subjected to axial vibration; when the first sliding assembly 42 resets, the first sliding assembly 42 provides a horizontal pushing force to the rotary blade, so that the rotary blade 6 is subjected to horizontal shaking, and through the collision with the inner side wall of the limiting frame 3, a better horizontal vibration effect is achieved.

[0079] It should be noted that the horizontal part 411 includes a horizontal plate 4111, a first recess 4112, a horizontal sliding groove 4113, a first baffle 4114 and a circular groove 4115; wherein the horizontal plate 4111 is arranged on the surface of the cutter head main body 1; the first recess 4112 is arranged on the top of the horizontal plate 4111, and the first recess 4112 is through on the side away from the vertical part 412 of the horizontal plate 4111; the horizontal sliding groove 4113 is arranged on the opposite two sides of the first recess 4112, and the horizontal sliding groove 4113 is parallel to the first recess 4112; the first baffle 4114 is arranged on the side of the horizontal plate 4111 away from the vertical part 412; the circular groove 4115 is arranged on the top of the horizontal plate 4111, and one end of the reset spring 44 is arranged in the circular groove 4115;

[0080] The vertical part 412 includes a vertical plate 4121, a second recess 4122, a vertical sliding groove 4123 and a second baffle 4124; wherein the vertical plate 4121 is arranged vertically on the side of the horizontal plate 4211 away from the first baffle 4114, and the vertical plate 4121 is integrally connected with the horizontal plate 4211; the second recess 4122 is arranged on the side of the vertical plate 4121 close to the horizontal plate 4111, and the second recess 4122 is through on the top side of the vertical plate 4121; the vertical sliding groove 4123 is arranged on the opposite two sides of the second recess 4122, and the vertical sliding groove 4123 is parallel to the second recess 4122; the second baffle 4124 is arranged on the top of the vertical plate 4121.

[0081] Further, the role of the first sliding assembly 42 and the second sliding assembly 43 in the L-shaped slide rail 41 is as follows: the first sliding assembly 42 is arranged in the first groove 4112 on the top of the horizontal plate 4111, and the bottom of the first sliding assembly 42 is connected with the horizontal sliding groove 4113 arranged on the opposite inner side walls of the first groove 4112, and the position of the first sliding assembly 42 is limited by the horizontal sliding groove 4113, so that the first sliding assembly 42 can only slide along the horizontal sliding groove 4113. The first baffle 4114 is connected with the horizontal plate 4111 by bolts, which means that the first sliding assembly 42 can be installed into the horizontal sliding groove 4113 by disassembling the first baffle 4114 and then from the side through which the horizontal plate 4111 and the first groove 4112 are connected, and then fixing the first baffle 4114 to prevent the first sliding assembly 42 from being separated from the horizontal plate 4111. Similarly, the second sliding assembly 43 is arranged in the second groove 4122 in the vertical plate 4121, and the two sides of the second sliding assembly 43 close to one end of the vertical plate 4121 are connected with the vertical sliding groove 4123 arranged on the opposite inner side walls of the second groove 4122, and the second baffle 4124 is arranged on the side through which the vertical plate 4121 and the second groove 4122 are connected, and the second baffle 4124 is connected with the vertical plate 4121 by bolts, so that the second sliding assembly 43 can be installed by disassembling the second baffle 4124. The one end of the reset spring 44 is arranged in the circular groove 4115, which provides a guide space for the reset spring 44, so that the device is more stable. When the first sliding assembly 42 is subjected to the thrust of the rotary tillage knife 6, the first sliding assembly 42 slides along the horizontal sliding groove 4113 in the first groove 4112 towards the second sliding assembly 43, and at the same time, the second sliding assembly 43 is extruded through the contact surface with the first sliding assembly 42, and the second sliding assembly 43 moves away from the rotary tillage knife 6 along the vertical sliding groove 4123 in the second groove 4122 after being extruded, so as to be separated from the rotary tillage knife 6. When the thrust of the rotary tillage knife 6 on the first sliding assembly 42 disappears, the second sliding assembly 43 is reset to the initial position under the action of the reset spring 44, contacts the rotary tillage knife 6, and provides an axial thrust to the rotary tillage knife 6, so that the rotary tillage knife 6 is axially vibrated. At the same time, the first sliding assembly 42 returns to the initial position along the horizontal sliding groove 4113, drives the rotary tillage knife 6 to swing around the rotary tillage knife fixing shaft 2, so as to provide a transverse swing, and the rotary tillage knife 6 is transversely vibrated. When the rotary tillage knife 6 collides with the inner side wall of the limiting frame 3, the degree of transverse vibration of the rotary tillage knife 6 is increased. Thus, the rotary tillage knife 6 is provided with transverse and axial double vibration effects.

[0082] It should be noted that the first slider assembly 42 comprises a first trapezoidal slider 421, a thin plate 422 and a sector block 423; the first trapezoidal slider 421 is arranged in the first groove 4112 and is in sliding connection with the horizontal sliding groove 4113; the thin plate 422 is fixedly arranged on the top of the first trapezoidal slider 421, and the thin plate 422 is provided with a hollow portion 4221, which is located above the second slider assembly 43; and the sector block 423 is fixedly arranged on the top of the thin plate 422 away from the first trapezoidal slider 421.

[0083] It should be noted that the second slider assembly 43 comprises a second trapezoidal slider 431 and a rubber head 432; the second trapezoidal slider 431 is arranged in the second groove 4122 and is in sliding connection with the vertical sliding groove 4123, the bottom of the second trapezoidal slider 431 is fixedly connected with the reset spring 44, and the inclined side of the second trapezoidal slider 431 is in contact with the inclined side of the first trapezoidal slider 421; and the rubber head 432 is arranged on the top of the second trapezoidal slider 43 and passes through the hollow portion 4221 to the top of the thin plate 422.

[0084] Further, the working process of the first slider assembly 42 and the second slider assembly 43 is as follows: when the rotary tiller blade 6 enters the soil, the rotary tiller blade 6 extrudes the sector block 423 due to the resistance of the soil, the sector block 423 drives the thin plate 422 to move towards the second slider assembly 43, the movement of the thin plate 422 drives the first trapezoidal slider 421 to slide in the horizontal sliding groove 4113 towards the second slider assembly 43, at this time, the inclined side of the first trapezoidal slider 421 and the inclined side of the second trapezoidal slider 431 have formed extrusion, since the inclined side of the first trapezoidal slider 421 and the inclined side of the second trapezoidal slider 431 are parallelly attached, and the inclined side of the first trapezoidal slider 421 gradually approaches the second trapezoidal slider 431 from the bottom to the top, and the inclined side of the second trapezoidal slider 431 gradually moves away from the first trapezoidal slider 421 from the bottom to the top, so when the first trapezoidal slider 421 slides along the horizontal sliding groove 4113 towards the second trapezoidal slider 431, the first trapezoidal slider 421 extrudes the second trapezoidal slider 431 through the contact surface of the second trapezoidal slider 431, so that the second trapezoidal slider 431 slides in the vertical sliding groove 4123 away from the rotary tiller blade 6, at this time, the rubber head 432 is separated from the rotary tiller blade 6, and the second trapezoidal slider 431 extrudes the return spring 44; when the rotary tiller blade 6 leaves the soil, the resistance of the soil to the rotary tiller blade 6 disappears, so that the pushing force of the rotary tiller blade 6 to the sector block 423 disappears, the second trapezoidal slider 431 starts to reset under the action of the return spring 44, the second trapezoidal slider 431 drives the rubber head 432 to move towards the rotary tiller blade 6 to contact and collide with the rotary tiller blade 6, so that the rubber head 432 collides with the rotary tiller blade 6 in the axial direction, thereby realizing the axial vibration of the rotary tiller blade 6, at the same time, the second trapezoidal slider 431 drives the first trapezoidal slider 421 to reset, thereby driving the thin plate 422 and the sector block 423 to reset, at this time, the rotary tiller blade 6 is pushed by the sector block 423 to reset, and the rotary tiller blade 6 produces lateral shaking, thereby providing a lateral vibration effect for the rotary tiller blade 6, at the same time, the rotary tiller blade 6 collides with the inner wall of the limiting frame 3, thereby increasing the lateral vibration effect of the rotary tiller blade 6.

[0085] It should be noted that the rotary tiller fixing shaft 2 comprises a base 21 and a blade shaft 22; wherein the base 21 is arranged on the surface of the blade disc main body 1; the blade shaft 22 is arranged on the top of the base 22, and the end wall of the blade shaft 22 away from the base 21 is provided with a thread 221.

[0086] Further, the mounting end of the rotary tiller blade 6 is sleeved on the part (smooth part) of the blade shaft 22 close to the base 21, a nut is added to the blade shaft 22 through the thread 221, so as to rotate and mount the rotary tiller blade 6 on the smooth part of the blade shaft 22, the movement space of the rotary tiller blade 6 along the axial direction of the blade shaft 22 is limited through the base 21 and the nut, and the rotary tiller blade 6 and the blade shaft 22 are gap-fitted, which allows the rotary tiller blade 6 and the blade shaft 22 to have a shaking space in the transverse direction of the blade shaft 22.

[0087] It should be noted that the limiting frame 3 comprises a limiting frame body 31 and a rubber pad 32; wherein the limiting frame body 31 is fixedly connected with the surface of the cutter head body 1 at both ends, and a threaded hole 311 is arranged at the middle position of the limiting frame body 31; the rubber pad 32 is arranged on the opposite two inner side walls of the limiting frame body 31.

[0088] Further, by arranging the rubber pad 32 on the opposite two inner side walls of the limiting frame body 31, since the rubber pad 32 has good elasticity, when the rotary tillage blade 6 collides with the rubber pad 32, the rubber pad 32 can provide a better transverse vibration effect; and the threaded hole 311 is arranged at the middle position of the limiting frame body 31, a bolt can be installed on the inner top wall of the limiting frame body 31 through the threaded hole 311, the distance between the bolt and the rotary tillage blade 6 is adjusted, the axial vibration amplitude of the rotary tillage blade 6 is adjusted, when the distance between the bolt and the rotary tillage blade 6 is close, due to the limitation of the bolt, the axial vibration amplitude of the rotary tillage blade 6 is small; similarly, when the distance between the bolt and the rotary tillage blade 6 is far, the axial vibration amplitude of the rotary tillage blade 6 is large; at the same time, a rubber pad can be added on the side where the bolt contacts the rotary tillage blade 6, which can improve the effect of vibration and also protect the rotary tillage blade 6 from being directly collided with the bolt to produce scratches.

[0089] According to the rotary tiller disc of the embodiment, the disc body 1 rotates under the drive of the rotary tiller rotating shaft. In the short time before the rotary tiller 6 rotates into the soil, the rotary tiller 6 swings around the rotary tiller fixing shaft 2 due to the gravity. After the swinging ends, the rotary tiller 6 leans against the rubber pad 32 at the end of the limiting clamp 3 away from the sector block 423, and at this time, the sector block 423 on the thin plate 422 is a certain distance away from the rotary tiller 6. In the axial vibration generating mechanism 4, in the initial state, due to the gravity of the second trapezoidal slider 431 itself, the second trapezoidal slider 431 is pressed against the return spring 44. In this state, the rubber head 432 fixed at the top of the second trapezoidal slider 431 has contacted and is pressed against the rotary tiller 6. When the rotary tiller 6 starts to rotate into the soil, due to the great resistance of the soil to the rotary tiller during the rotary tillage, the rotary tiller 6 swings around the rotary tiller fixing shaft 2 under the resistance. When the rotary tiller 6 enters the soil, due to the resistance of the soil, the rotary tiller 6 presses the sector block 423, the sector block 423 drives the thin plate 422 to move towards the second trapezoidal slider 431, the movement of the thin plate 422 drives the first trapezoidal slider 421 to slide in the horizontal sliding groove 4113 towards the second trapezoidal slider 431. At this time, the inclined side of the first trapezoidal slider 421 and the inclined side of the second trapezoidal slider 431 have formed a pressing. Since the inclined side of the first trapezoidal slider 421 and the inclined side of the second trapezoidal slider 431 are parallelly attached, and the inclined side of the first trapezoidal slider 421 gradually approaches the second trapezoidal slider 431 from the bottom to the top, and the inclined side of the second trapezoidal slider 431 gradually moves away from the first trapezoidal slider 421 from the bottom to the top, when the first trapezoidal slider 421 slides along the horizontal sliding groove 4113 towards the second trapezoidal slider 431, the first trapezoidal slider 421 presses the second trapezoidal slider 431 through the contact surface between them, so that the second trapezoidal slider 431 slides in the vertical sliding groove 4123 away from the rotary tiller 6. At this time, the rubber head 432 is separated from the rotary tiller 6, and the second trapezoidal slider 431 presses the return spring 44. When the rotary tiller 6 leaves the soil, the resistance of the soil to the rotary tiller 6 disappears, so that the pushing force of the rotary tiller 6 to the sector block 423 disappears, and the second trapezoidal slider 431 starts to reset under the action of the return spring 44. The second trapezoidal slider 431 drives the rubber head 432 to move towards the rotary tiller 6 to contact and collide with the rotary tiller 6, so as to realize the axial collision of the rotary tiller 6 by the rubber head 432, and realize the axial vibration of the rotary tiller 6. At the same time, the second trapezoidal slider 431 drives the first trapezoidal slider 421 to reset, so as to drive the thin plate 422 and the sector block 423 to reset. At this time, the rotary tiller 6 is pushed by the sector block 423 to reset, and swings laterally, so as to provide a lateral vibration effect for the rotary tiller 6. At the same time, the rotary tiller 6 collides with the inner wall of the limiting frame 3, so as to increase the lateral vibration effect of the rotary tiller 6.

[0090] Compared with the prior art, the rotary tiller disc according to the embodiment has the following beneficial effects:

[0091] In the initial state, the rotary tiller is placed on the top of the thin plate, in contact with the rubber head and being extruded to a certain extent; when the rotary tiller enters the soil, the soil provides a resistance to the rotary tiller, so that the rotary tiller pushes the fan-shaped block to drive the first trapezoidal slider to move in the direction of the second trapezoidal slider; since the inclined surfaces of the first trapezoidal slider and the second trapezoidal slider are in contact with each other and can produce relative sliding through extrusion, the second trapezoidal slider is extruded to move the reset spring, so that the reset spring is extruded; at the moment when the rotary tiller leaves the soil, the resistance provided by the soil to the rotary tiller disappears, the reset spring is reset, and the rubber head on the second trapezoidal slider bounces back to the original position and collides with the rotary tiller, thereby providing an axial force to the rotary tiller; in addition, when the rotary tiller is subjected to the axial force, the rotary tiller performs axial vibration, and through the axial vibration, the soil adhering to the rotary tiller is shaken off; at the moment when the rotary tiller leaves the soil, the rotary tiller is provided with a transverse force through the reset of the fan-shaped block, the rotary tiller performs transverse shaking and collides with the rubber pads on the inner walls of the two sides of the limiting frame, thereby providing a transverse vibration to the rotary tiller, so that the soil adhering to the rotary tiller is shaken off; through the use of the difference in resistance when the rotary tiller enters the soil and leaves the soil, the device can produce double vibration effects in the transverse and axial directions, so that the soil on the rotary tiller is shaken off through vibration, thereby achieving the effect of removing the soil adhering to the rotary tiller; in addition, through the gap cooperation between the rotary tiller and the rotary tiller fixing shaft, the rotary tiller can perform relatively large shaking; without affecting the normal use of the rotary tiller, the rotary tiller can be provided with a relatively large shaking space, thereby improving the vibration effects in the transverse and axial directions; through the increase of the adjusting mechanism, a preset pushing force or pulling force can be provided to the axial vibration generating mechanism, so that the device can maintain stable vibration effects under different soil types and humidity conditions, thereby improving the flexibility of the device.
