DETAILED DESCRIPTION

[0024] In order to more clearly illustrate the structural features and effects of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] See also Figure 1-Figure 6The intelligent high-speed stubble breaking device of the no-tillage planter in one embodiment of the present invention comprises a frame component 1, wherein the frame component 1 comprises a main frame 101 and a main drive shaft 102, wherein the main frame 101 is provided with the main drive shaft 102 as a fixed axis; a stubble breaking knife assembly 2, wherein the stubble breaking knife assembly 2 comprises a first frame arm 201, a second frame arm 202, a third frame arm 203 and a secondary shaft 208, wherein a plurality of the first frame arms 201 are rotatably sleeved on the main drive shaft 102, a second frame arm 202 is provided at the end of the first frame arm 201, and the first frame arm 20 1 and the second frame arm 202 are rotatably connected through the secondary shaft 208, the other end of the second frame arm 202 is fixedly connected to the third frame arm 203, the third frame arm 203 is rotatably provided with a stubble breaking knife 205, the stubble breaking knife 205 and the secondary shaft 208 as well as the secondary shaft 208 and the main driving shaft 102 are all connected through synchronous belt transmission; a depth limiting wheel assembly 3, the depth limiting wheel assembly 3 includes a side bracket 301 and a depth limiting wheel 302, one end of the side bracket 301 is fixedly connected to the main frame 101, and the other end of the side bracket 301 is fixedly assembled with a depth limiting wheel 302.

[0026] In actual application of this embodiment, when the device is used to break the stubble of a seed drill, during the operation of the device, the main frame 101 is fixedly installed on the agricultural machinery, and the main frame 101 is driven by the agricultural machinery to move on the field. The stubble breaking knife 209 is used to break the residual roots in the land, and the depth limiting wheel 302 moves in the soil with the agricultural machinery, and the depth limiting wheel 302 can be used to measure the depth of the current stubble breaking position, and several independent stubble breaking knives 209 are equipped with independent depth limiting wheels 302 for stubble breaking depth detection. Since the first frame arm 201 is rotatably sleeved on the main drive shaft 102, and the second frame arm 202 is rotatably connected to the first frame arm 201 through the secondary shaft 208, the third frame arm 203 fixedly connected to the second frame arm 202 is rotatably provided with a stubble breaking knife 2 09, the stubble breaking knife 209 and the secondary shaft 208 are connected by a synchronous belt transmission, and the secondary shaft 208 and the main driving shaft 102 are connected by a synchronous belt transmission. Therefore, when the main driving shaft 102 rotates on a fixed axis, when the angle between the first frame arm 201 and the second frame arm 202 changes, the main driving shaft 102 and the stubble breaking knife 209 always maintain transmission. The depth limiting wheel 302 can detect the depth of the current stubble breaking position during movement. When the stubble breaking depth is too large, the stubble breaking knife 209 can be controlled to rise in the vertical direction to reduce the stubble breaking depth at the current position. Conversely, the stubble breaking depth of the stubble breaking knife 209 at the current position can be independently controlled by the measurement result of the depth limiting wheel 302, so that the stubble breaking depth at each position of the device can remain consistent during movement.

[0027] See also Figure 3In a preferred embodiment of the present invention, the stubble cutting knife assembly 2 also includes a guide rod 204, a slider 205, an adjusting shaft 206 and a socket 207. The guide rod 204 is fixedly arranged between the second frame arm 202 and the third frame arm 203.

The adjusting shaft 206 is also provided with a socket 207.

[0028] In actual application of this embodiment, the guide rod 204 is fixedly arranged between the second frame arm 202 and the third frame arm 203, and the slider 205 is slidably assembled on the guide rod 204. One end of the slider 205 is also rotatably assembled with an adjusting shaft 206, and a socket 207 is arranged on the adjusting shaft 206. The depth adjustment rod 406 is slidably inserted into the socket 207, so that when the depth adjustment rod 406 slides horizontally on one side of the main frame 101, the adjusting shaft 206 can push the slider 205 to move synchronously. Since the slider 205 is limitedly slidably assembled on the guide rod 204, during the movement, the slider 205 can synchronously pull the second frame arm 202 and the third frame arm 203 to rotate around the axis of the secondary shaft 208, thereby adjusting the height of the slider 205 in the vertical direction, thereby adjusting the stubble breaking depth of the stubble breaking knife 209 according to the push-pull position of the depth adjustment rod 406.

[0029] See also Figure 4 In a preferred embodiment of the present invention, the depth limiting wheel assembly 3 also includes a limiting groove 303, a depth limiting block 304, a side roller 305 and a notch plate 310.

The depth limiting block 304 is slidingly assembled in the limiting groove 303. One end of the depth limiting block 304 is also rotatably assembled with a side roller 305. The notch plate 310 is sleeved on the side roller 305, and the notch plate 310 is slidingly assembled on the main frame 101.

[0030] When the depth limiting wheel 302 is rolled over the field, the depth limiting block 304 and the ground pressing block 306 rotate toward the ground end. After the depth limiting wheel 302 partially cuts into the soil, the ground pressing block 306 abuts against the ground end, so that the depth limiting block 304 slides in the limit groove 303. At this time, the side roller 305 at one end of the depth limiting block 304 synchronously pulls the position of the notch plate 310 in the vertical direction, and the side roller 305 rolls in the notch of the notch plate 310. When the ground pressing block 306 is pressed against the ground end, the notch plate 310 can judge the stubble breaking depth at the current position according to the depth of the depth limiting wheel 302 cutting into the soil.

[0031] See also Figure 5 and Figure 6 In a preferred embodiment of the present embodiment, the depth limiting wheel assembly 3 also includes a ground pressing block 306, a first transmission wheel 307, a second transmission wheel 308 and a fan-shaped plate 309. The ground pressing block 306 is fixedly installed on the other side of the depth limiting block 304, one end of the first transmission wheel 307 is fixedly connected to the depth limiting wheel 302, and the other end of the ground pressing block 306 is transmission-connected to the second transmission wheel 308, and the fan-shaped plate 309 is coaxially fixedly connected to the second transmission wheel 308.

[0032] In actual application of this embodiment, the first transmission wheel 307 is coaxially fixedly connected to the depth limiting wheel 302, one end of the second transmission wheel 308 is fixedly assembled on the side bracket 301, the other end of the second transmission wheel 308 is connected to the first transmission wheel 307 through a synchronous belt transmission, and the diameter of the second transmission wheel 308 is smaller than the diameter of the first transmission wheel 307, so that the rotation angular velocity of the second transmission wheel 308 is equal to the rotation angular velocity of the first transmission wheel 307, so that when the ground pressing block 306 at one end of the depth limiting wheel 302 rotates to the ground side, the fan-shaped plate 309 at one end of the second transmission wheel 308 rotates synchronously to the bottom side in the vertical direction.

[0033] See also Figure 6 In a preferred embodiment of the present invention, the high-speed stubble breaking device of the intelligent no-till seeder also includes a transmission component 4, which includes a first hydraulic cylinder 401, a hydraulic rod 402, a branch guide tube 403, a second hydraulic cylinder 404, a pulling block 405 and a depth adjustment rod 406. The first hydraulic cylinder 401 is fixedly arranged on the main frame 101, the hydraulic rod 402 is slidably inserted in the first hydraulic cylinder 401 and fixedly connected to the notch plate 310, the branch guide tube 403 is fixedly arranged on one side of the main frame 101 and is connected to the first hydraulic cylinder 401, one end of the second hydraulic cylinder 404 is connected to the branch guide tube 403, and the other end of the second hydraulic cylinder 404 is equipped with a pulling block 405, the pulling block 405 is slidably assembled in the main frame 101, and a depth adjustment rod 406 is also fixedly arranged at one end of the pulling block 405, and the depth adjustment rod 406 is slidably assembled in the socket 207.

[0034] In actual application of this embodiment, one end of the first hydraulic cylinder 401 is fixedly mounted on the main frame 101, and the hydraulic rod 402 at the other end of the first hydraulic cylinder 401 is fixedly connected to the notch plate 310. When the side roller 305 on one side of the depth limiting wheel 302 is in motion, the notch plate 310 slidingly connected thereto moves synchronously in the vertical direction. When the stubble breaking depth at the current position is too large, the depth limiting block 304 is closer to the center position of the depth limiting wheel 302, so that the side roller 305 on one side of the depth limiting block 304 drives the notch plate 310 to move toward the center side of the depth limiting wheel 302. At this time, the hydraulic Under traction, the rod 402 pumps out the hydraulic oil in the first hydraulic cylinder 401, and makes the hydraulic oil flow along the branch conduit 403 to the second hydraulic cylinder 404. When the interior of the second hydraulic cylinder 404 is in a positive pressure state, the movable rod at one end of the second hydraulic cylinder 404 can pull the pulling block 405 to slide in a directional manner when pushed out, so that the pulling block 405 drives the depth adjustment rod 406 at one end thereof to move synchronously. During the movement, the depth adjustment rod 406 can drive the stubble breaking knife 209 to be lifted in the vertical direction through the jack 207, so that when the stubble breaking depth is too large, the stubble breaking knife 209 is automatically controlled to be lifted.

[0036] In actual application of this embodiment, since the second transmission wheel 308 and the first transmission wheel 307 rotate at the same angular velocity, when the depth limit block 304 and the side roller 305 move toward the ground end, the fan-shaped plate 309 at one end of the second transmission wheel 308 moves synchronously to abut against the driven plate 408, so that the driven plate 408 overcomes the elastic force to pull the trigger plate 409 to move, and the trigger plate 409 can control the valve port on one side of the valve port regulator 407 to open during the movement, so that the first hydraulic cylinder 408 The hydraulic oil in 01 can be pumped into the second hydraulic cylinder 404 through the branch conduit 403, and the valve port between the first hydraulic cylinder 401 and the auxiliary oil tank is closed synchronously. When the depth limit block 304 rotates away from the ground end, the fan plate 309 rotates away from the side of the driven plate 408.
