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

[0073] Embodiment 1

[0074] A rotary tiller disc comprises a disc body 1, a plurality of rotary tiller blade fixed shafts 2, a plurality of limit frames 3 and a plurality of axial vibration generating mechanisms 4; wherein, the plurality of rotary tiller blade fixed shafts 2 are arranged in a circular pattern on the surface of the disc body 1; each rotary tiller blade fixed shaft 2 is used to assemble a rotary tiller blade 6, and the rotary tiller blade 6 is rotationally connected with the rotary tiller blade fixed shaft 2 in a clearance fit; a plurality of limit frames 3 are arranged on the surface of the disc body 1 in a one-to-one correspondence with the plurality of rotary tiller blade fixed shafts 2, and each limit frame 3 is located on a side of the corresponding rotary tiller blade fixed shaft 2 away from the center of the disc body 1; the limit frame 3 is used to limit the rotation angle of the corresponding rotary tiller blade 6; a plurality of axial vibration generating mechanisms 4 are arranged on the surface of the disc body 1 in a one-to-one correspondence with the plurality of limit frames 3, and each axial vibration generating mechanism 4 is located on a side of the corresponding limit frame 3 away from the corresponding rotary tiller blade fixed shaft 2; each axial vibration generating mechanism 4 can contact with the corresponding rotary tiller blade 6, and is used to apply an axial force to the rotary tiller blade 6 to cause it to vibrate axially.

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

[0076] Furthermore, the mounting end of the rotary tiller 6 is passed through the cavity of the limiting frame 3 from one end of the limiting frame 3 close to the axial vibration generating mechanism 4 to reach the rotary tiller fixed shaft 2, and the rotary tiller 6 is installed on the rotary tiller fixed shaft 2, so that the rotary tiller 6 is rotatably connected with the rotary tiller fixed shaft 2, and is a clearance fit; the cutter head body 1 is installed on the rotating shaft of the rotary tiller, and when the rotary tiller 6 enters the soil, the soil gives a resistance to the rotary tiller 6, and the rotary tiller 6 uses the resistance given by the soil to give the axial vibration generating mechanism 4 a lateral extrusion, and through the internal structure of the axial vibration generating mechanism 4, gives itself an axial extrusion, and when the rotary tiller 6 leaves the soil, the resistance given to the rotary tiller 6 by the soil disappears, and the rotary tiller 6 6, the lateral and axial extrusion of the axial vibration generating mechanism 4 disappears. At this time, the axial vibration generating mechanism 4 is reset to give the rotary blade 6 an axial (in a direction parallel to the axis of the cutter disc body 1, the same below) elastic force, so that the rotary blade 6 vibrates axially. At the same time, when the axial vibration generating mechanism 4 is reset, it can also push the rotary blade 6 laterally (in a direction parallel to the surface of the cutter disc body 1, the same below), so that the rotary blade 6 collides with the inner wall of the limit frame 3, thereby generating lateral vibration; through the cooperation of the axial vibration generating mechanism 4 and the limit frame 3, the rotary blade 6 can generate axial and lateral dual vibrations when leaving the soil, thereby increasing the device's effect of removing soil attached to the rotary blade 6.

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

[0078] Furthermore, the action process of the rotary blade 6 on the axial vibration mechanism 4 is specifically as follows: initially, the top of the second slider assembly 43 contacts the rotary blade 6. When the rotary blade 6 enters the soil, the first slider assembly 42 located at the horizontal portion 411 of the L-shaped slide rail 41 is pushed by the rotary blade 6, thereby sliding along the horizontal portion 411 of the L-shaped slide rail 41 toward the vertical portion 412, squeezing the second slider assembly 43. The second slider assembly 43 is slidably connected to the vertical portion 412. Therefore, when the first slider assembly 42 slides, extrusion is formed through the contact surface between the first slider assembly 42 and the second slider assembly 43, thereby pushing the second slider assembly 43 to slide downward, squeezing the reset spring 44, so that the second slider assembly 43 Component 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, and the squeezing of the rotary blade 6 to the first slider component 42 disappears. At this time, the reset spring 44 is reset, driving the second slider component 43 and the first slider component 42 to reset. When the second slider component 43 is reset, the second slider component 43 contacts the rotary blade 6 again and provides an axial vibration force to the rotary blade, causing the rotary blade to vibrate axially. When the first sliding component 42 is reset, the first sliding component 42 gives the rotary blade a lateral thrust, causing the rotary blade 6 to shake laterally, and by colliding with the inner wall of the limit frame 3, a better lateral vibration effect is achieved.

[0079] It should be noted that the horizontal portion 411 includes a horizontal plate 4111, a first groove 4112, a horizontal slide 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 body 1; the first groove 4112 is arranged at the top of the horizontal plate 4111, and the first groove 4112 is connected with the side of the horizontal plate 4111 away from the vertical portion 412; the horizontal slide groove 4113 is arranged on two opposite sides of the first groove 4112, and the horizontal slide groove 4113 is parallel to the first groove 4112; the first baffle 4114 is arranged on the side of the horizontal plate 4111 away from the vertical portion 412; the circular groove 4115 is arranged at the top of the horizontal plate 4111, and one end of the return spring 44 is arranged in the circular groove 4115;

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

[0081] Furthermore, the action process of the first sliding component 42 and the second sliding component 43 in the L-shaped slide rail 41 is specifically as follows: the first sliding component 42 is set in the first groove 4112 at the top of the horizontal plate 4111, and the two sides of the bottom of the first sliding component 41 are slidably connected with the horizontal sliding grooves 4113 set in the two opposite inner walls of the first groove 4112, and the position of the first sliding component 42 is limited by the horizontal sliding grooves 4113, so that the first sliding component 42 can only slide along the horizontal sliding grooves 4113, and the first baffle plate 4114 is set, and the first baffle plate 4114 is connected to the horizontal plate 4111 by bolts, which means that the first baffle plate 4114 can be set to the horizontal plate 4111 by the first baffle plate 4114. 4, and then install the first slider assembly 42 into the horizontal slide groove 4113 from the side where the horizontal plate 4111 and the first groove 4112 are connected, and then fix the first baffle plate 4114 to prevent the first slider assembly 42 from being separated from the horizontal plate 4111; similarly, the second slider assembly 43 is arranged in the second groove 4122 in the vertical plate 4121, and one end of the second slider assembly 43 close to the vertical plate 4121 on both sides is slidably connected with the vertical slide grooves 4123 arranged on the two opposite inner side walls of the second groove 4122, and the second baffle plate 4124 is arranged on the side where the vertical plate 4121 and the second groove 4122 are connected, and the second baffle plate 4124 and the vertical plate 4121 are connected by screws. The second slider assembly 43 is connected by bolts, so that the installation of the second slider assembly 43 can be achieved by disassembling the second baffle plate 4124; through the design of the circular groove 4115, one end of the return spring 44 is arranged in the circular groove 4115, giving the return spring 44 a guiding space, making the device more stable; when the first sliding assembly 42 is acted upon by the thrust of the rotary tiller 6, the first sliding assembly 42 slides toward the second slider assembly 43 along the horizontal slide groove 4113 in the first groove 4112, and at the same time, the second slider assembly 43 is squeezed through the contact surface with the second slider assembly 43. After being squeezed, the second slider assembly 43 moves in the second groove 4122 along the vertical slide groove 4123 in the direction away from the rotary tiller 6 Move, thereby breaking contact with the rotary tiller 6; when the thrust of the rotary tiller 6 on the first slider assembly 42 disappears, the second slider assembly 43 is reset under the action of the reset spring 44, returns to the initial position, contacts the rotary tiller 6, and gives the rotary tiller 6 an axial thrust, causing the rotary tiller 6 to vibrate axially; at the same time, the first slider assembly 42 returns to the initial position along the horizontal slide groove 4113, driving the rotary tiller 6 to shake around the rotary tiller fixed axis 2, thereby providing a lateral shake, causing the rotary tiller 6 to vibrate laterally, and when the rotary tiller 6 collides with the inner wall of the limit frame 3, the lateral vibration degree of the rotary tiller 6 is increased; thereby providing the rotary tiller 6 with a dual vibration effect of lateral and axial directions at the same time.

[0082] It should be noted that the first slider assembly 42 includes a first trapezoidal slider 421, a thin plate 422 and a fan-shaped block 423; wherein the first trapezoidal slider 421 is arranged in the first groove 4112, and the first trapezoidal slider 421 is slidably connected to the horizontal slide groove 4113; the thin plate 422 is fixedly arranged on the top of the first trapezoidal slider 421, and a hollow portion 4221 is opened on the thin plate 422, and the hollow portion 4221 is located above the second slider assembly 43; the fan-shaped 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 includes a second trapezoidal slider 431 and a rubber head 432; the second trapezoidal slider 431 is arranged in the second groove 4122, the second trapezoidal slider 431 is slidably connected to the vertical slide groove 4123, the bottom of the second trapezoidal slider 431 is fixedly connected to the return 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; the rubber head 432 is arranged at the top of the second trapezoidal slider 43, and the rubber head 432 passes through the hollow portion 4221 to the top of the thin plate 422.

[0084] Furthermore, the working process of the first slider assembly 42 and the second slider assembly 43 is as follows: when the rotary tiller 6 enters the soil, due to the resistance of the soil, the rotary tiller 6 squeezes the fan-shaped block 423, and the fan-shaped block 423 drives the thin plate 422 to move in the direction close to the second slider assembly 43. The movement of the thin plate 422 drives the first trapezoidal slider 421 to slide in the horizontal slide groove 4113 in the direction of 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 The first trapezoidal slider 421 is pressed against the second trapezoidal slider 431 by the inclined surface thereof, and the inclined surface of the first trapezoidal slider 421 gradually approaches the second trapezoidal slider 431 from the bottom to the top, and the inclined surface of the second trapezoidal slider 431 gradually moves away from the first trapezoidal slider 421 from the bottom to the top. Therefore, when the first trapezoidal slider 421 slides along the horizontal slide groove 4113 toward the second trapezoidal slider 431, the first trapezoidal slider 421 contacts the second trapezoidal slider 431. The trapezoidal slider 431 is squeezed to make the second trapezoidal slider 431 slide in the vertical slide groove 4123 in the direction 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 squeezes the reset spring 44; when the rotary tiller 6 leaves the soil, the resistance of the soil to the rotary tiller 6 disappears, so that the thrust of the rotary tiller 6 on the fan-shaped block 423 disappears, and the second trapezoidal slider 431 starts to reset under the action of the reset spring 44, and the second trapezoidal slider 431 drives the rubber head 432 to move toward the rotary tiller 6 The rotary tiller 6 moves to come into contact and collide with the rotary tiller 6, thereby axially colliding with the rotary tiller 6 through the rubber head 432, thereby realizing axial vibration of the rotary tiller 6. At the same time, the second trapezoidal slider 431 drives the first trapezoidal slider 42 to reset, thereby driving the thin plate 422 and the fan-shaped block 423 to reset. At this time, the rotary tiller 6 is thrusted by the reset of the fan-shaped block 423, resulting in lateral shaking, thereby providing a lateral vibration effect to the rotary tiller 6. At the same time, the rotary tiller 6 collides with the inner wall of the limit frame 3, thereby increasing the lateral vibration effect of the rotary tiller 6.

[0085] It should be noted that the rotary blade fixed shaft 2 includes a base 21 and a blade shaft 22; wherein the base 21 is arranged on the surface of the blade disc body 1; the blade shaft 22 is arranged on the top of the base 22, and a thread 221 is arranged on the side wall of the blade shaft 22 away from the base 21.

[0086] Furthermore, the mounting end of the rotary blade 6 is sleeved on the part (smooth part) of the blade shaft 22 close to the base 21, and a nut is added to the blade shaft 22 through the thread 221, so that the rotary blade 6 is rotatably mounted on the smooth part of the blade shaft 22, and the base 21 and the nut limit the axial movement space of the rotary blade 6 along the blade shaft 22, while the rotary blade 6 and the blade shaft 22 are clearance-fitted, which allows the rotary blade 6 and the blade shaft 22 to have shaking space along the lateral direction of the blade shaft 22.

[0087] It should be noted that the limit frame 3 includes a limit frame body 31 and a rubber pad 32; wherein, both ends of the limit frame body 31 are fixedly connected to the surface of the cutter disc body 1, and a threaded hole 311 is provided in the middle position of the limit frame body 31; the rubber pad 32 is arranged on the two opposite inner side walls of the limit frame body 31.

[0088] Furthermore, by arranging rubber pads 32 on the two opposite inner walls of the limit frame body 31, since the rubber pads 32 have good elasticity, when the rotary tiller 6 collides with the rubber pads 32, the rubber pads 32 can provide a better lateral vibration effect; and a threaded hole 311 is provided in the middle position of the limit frame body 31, and a bolt can be installed on the inner top wall of the limit frame body 31 through the threaded hole 311, and the axial vibration amplitude of the rotary tiller 6 is adjusted by adjusting the distance between the bolt and the rotary tiller 6. When the distance between the bolt and the rotary tiller 6 is close, the axial vibration amplitude of the rotary tiller 6 is small due to the limitation of the bolt; similarly, when the distance between the bolt and the rotary tiller 6 is far, the axial vibration amplitude of the rotary tiller 6 is large; at the same time, a rubber gasket can be added to the side where the bolt contacts the rotary tiller 6, which can not only improve the vibration effect but also protect the rotary tiller 6 to prevent the rotary tiller 6 from directly colliding with the bolt and causing scratches.

[0089] According to a rotary tiller blade disc of the present embodiment, the blade disc body 1 rotates driven by the rotary tiller shaft. In a short period of time before the rotary tiller blade 6 is rotated into the soil, due to the effect of gravity, the rotary tiller blade 6 swings around the rotary tiller blade fixed shaft 2. After the shaking ends, the rotary tiller blade 6 rests on the rubber pad 32 at the end of the limit clamp 3 away from the fan-shaped block 423. At this time, the fan-shaped block 423 on the thin plate 422 is at a certain distance from the rotary tiller blade 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 has a certain extrusion on the reset spring 44. In this state, the rubber head 432 fixed on the top of the second trapezoidal slider 431 has come into contact with the rotary tiller blade 6, and there is a The rotary tiller 6 starts to rotate into the soil, and due to the large resistance of the soil to the rotary tiller during the rotary tillage process, the rotary tiller 6 shakes around the rotary tiller fixed shaft 2 under the action of the resistance. When the rotary tiller 6 enters the soil, due to the resistance of the soil, the rotary tiller 6 squeezes the sector block 423, and the sector block 423 drives the thin plate 422 to move in the direction close to the second trapezoidal slider 431. The movement of the thin plate 422 drives the first trapezoidal slider 421 to slide in the horizontal slide groove 4113 in the direction of 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 an extrusion. Since the inclined side of the first trapezoidal slider 421 is parallel to the inclined side of the second trapezoidal slider 431, The inclined surface of the first trapezoidal slider 421 gradually approaches the second trapezoidal slider 431 from the bottom to the top, and the inclined surface of the second trapezoidal slider 431 gradually moves away from the first trapezoidal slider 421 from the bottom to the top. Therefore, when the first trapezoidal slider 421 slides along the horizontal slide groove 4113 in the direction close to the second trapezoidal slider 431, the first trapezoidal slider 421 squeezes the second trapezoidal slider 431 through the contact surface with the second trapezoidal slider 431, so that the second trapezoidal slider 431 slides in the vertical slide groove 4123 in the direction away from the rotary tiller 6. At this time, the rubber head 432 separates from the rotary tiller 6, and the second trapezoidal slider 431 squeezes 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 thrust of the rotary blade 6 on the sector block 423 disappears, and the second trapezoidal slider 431 begins to reset under the action of the reset spring 44. The second trapezoidal slider 431 drives the rubber head 432 to move toward the rotary blade 6 until it contacts and collides with the rotary blade 6, thereby axially colliding with the rotary blade 6 through the rubber head 432 to achieve axial vibration of the rotary blade 6. At the same time, the second trapezoidal slider 431 drives the first trapezoidal slider 42 to reset, thereby driving the thin plate 422 and the sector block 423 to reset. At this time, the rotary blade 6 is pushed back by the sector block 423 to generate lateral shaking, thereby providing a lateral vibration effect to the rotary blade 6. At the same time, the rotary blade 6 collides with the inner wall of the limit frame 3 to increase the lateral vibration effect of the rotary blade 6.

[0090] Compared with the prior art, the rotary tillage blade of this 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 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 reset spring, so that the reset spring is squeezed; when the rotary tiller leaves the soil, the resistance of the soil to the rotary tiller disappears, the reset 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 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 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 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 removing the soil attached to the rotary tiller; in addition, through the clearance fit between the rotary tiller and the fixed shaft of the rotary tiller, the rotary tiller can produce a larger shake, and without affecting the normal use of the rotary tiller, a larger shaking space can be provided for the rotary tiller, 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.
