The rotating shaft 204 passes through the end of the second pulley 203 and is rotatably installed in the machine body 1. The surface of the rotating shaft 204 is fixedly connected to the collecting wheel 205.

[0019] The rotation of the rotating shaft 102 drives the first pulley 201 to rotate, and the kinetic energy of the first pulley 201 is transmitted to the second pulley 203 via the first belt 202. The second pulley 203 rotates, and the second pulley 203 drives the rotating shaft 204 to rotate in the body 1. The rotation of the rotating shaft 204 drives the collecting wheel 205 fixedly connected thereto to rotate in the same direction.

[0020] A plurality of bottom mounting rods 206 are fixedly installed on the surface of the collecting wheel 205, one end of four first springs 214 are fixedly connected to the inner surface of the bottom mounting rod 206, the other end of the first spring 214 is fixedly connected to the mounting plate 213, the mounting plate 213 is fixedly arranged on the outer surface of the sleeve rod 207, the first spring 214 is sleeved on the outer surface of the first telescopic rod 215, one end of the first telescopic rod 215 is fixedly connected to the inner surface of the bottom mounting rod 206, and the other end is fixedly connected to the mounting plate 213, the sleeve rod 207 is slidably installed in the bottom mounting rod 206, and the sleeve rod 207 is close to the rotating shaft 204 A wedge block 212 is set at the end, and the wedge block 212 is in contact with one end of the wedge rod 211.

[0021] The bottom mounting rod 206 will rotate along with the collection wheel 205, and the sleeve rod 207 in the bottom mounting rod 206 will rotate accordingly, and the sleeve rod 207 and the collection teeth 208 on the sleeve rod 207 will rotate accordingly, and the straw will be collected by the collection teeth 208; When it is necessary to adjust the distance of the collecting tooth 208 from the ground, the fixing screw 210 can be loosened, and then the rotating rod 209 can be screwed to rotate the rotating rod 209. The rotating rod 209 is fixedly connected to the wedge rod 211, and the wedge rod 211 will rotate accordingly. Since the inclined surface of the wedge block 212 is in contact with the inclined surface of one end of the wedge rod 211, the wedge block 212 will move away from the rotating rod 209 under the thrust of the wedge rod 211, and the sleeve rod 207 will move accordingly. At this time, the first spring 214 is extended, the first telescopic rod 215 is extended, and the sleeve rod 207 drives the collecting tooth 208 connected thereto to move. Conversely, the first spring 214 is shortened, the first telescopic rod 215 is shortened, the wedge block 212 will move toward the rotating rod 209, and the sleeve rod 207 and the collecting tooth 208 will move accordingly. Secondly, the collecting teeth 208 can also be installed in different positions through the multiple screw holes on the sleeve rod 207, thereby achieving height adjustment or replacement of a single collecting tooth 208.

[0022] One side of the second pulley 203 is fixedly connected to the third pulley 301, and one end of the second belt 302 is sleeved on the surface of the third pulley 301, and the other end of the second belt 302 is sleeved on the fourth pulley 303.

The surface of the toggle rod 304 is in contact with the inner surface of the elliptical groove 306 on the side of the flap 305. The flap 305 is rotatably installed in the body 1, and an elliptical groove 306 is provided on each side of the flap 305 away from the fourth pulley 303. The inner surface of the elliptical groove 306 is in contact with the driven rod 304. 07 surface contact connection, one end of the driven rod 307 is rotationally connected to the body 1, one end of two second springs 308 are fixedly connected to the driven rod 307, the other end of the second spring 308 is fixedly connected to the body 1, the second spring 308 is sleeved on the outer surface of the second telescopic rod 309, one end of the second telescopic rod 309 is fixedly connected to the driven rod 307, and the other end is fixedly connected to the body 1, a plurality of collecting rods 310 are arranged on one side of the flap 305, the collecting rods 310 and the collecting teeth 208 are cross-arranged, six rows of collecting teeth 208 are arranged on the collecting wheel 205, and five collecting rods 310 are arranged on the flap 305.

[0023] The rotation of the second pulley 203 drives the third pulley 301 to rotate. The second pulley 203 and the third pulley 301 are of the same size. The third pulley 301 drives the fourth pulley 303 to rotate through the second belt 302, and the toggle rod 304 on one side of the fourth pulley 303 will perform a circular motion accordingly. The toggle rod 304 is in contact with the surface of the elliptical groove 306, so the toggle rod 304 will apply pressure to the surface of the elliptical groove 306, thereby causing the elliptical groove 306 to move repeatedly, and the flap 305 will move repeatedly. The driven rod 307 plays a connecting and limiting role. When the flap 305 moves repeatedly, the driven rod 307 will also rotate accordingly, and the second spring 308 and the second telescopic rod 309 will extend and shorten accordingly. When the toggle rod 304 rotates to the bottom, the flap 305 is in a horizontal state, and the collecting rod 310 at the end of the flap 305 pushes the straw collected on the collecting teeth 208 onto the flap 305. When the toggle rod 304 gradually rotates to the top, the flap 305 will gradually tilt, and the straw falls onto the conveyor belt 401.

[0024] In order to preliminarily filter the mud and sand in the straw, a sieve plate slide groove is arranged on the surface of the flap 305, and the sieve plate 501 is slidably installed in the sieve plate slide groove, one end of the sieve plate 501 is fixedly connected to one end of the steel wire rope 502, and the other end of the steel wire rope 502 extends out of the flap 305 and is fixedly connected to the body 1, and the other end of the sieve plate 501 is fixedly connected to one end of the third spring 503, and the other end of the third spring 503 is connected to the flap 305. The third spring 503 is sleeved on the outer surface of the third telescopic rod 504, and one end of the third telescopic rod 504 is fixedly connected to the sieve plate 501, and the other end is fixedly connected to the flap 305.

[0025] In the initial state, the wire rope 502 is in a slightly taut state. When the flap 305 rotates and tilts, the wire rope 502 pulls the sieve plate 501 to slide toward the wire rope 502, and the third spring 503 and the third telescopic rod 504 extend. When the flap 305 rotates and gradually becomes horizontal, the pulling force of the third spring 503 resets the sieve plate 501 and the third telescopic rod 504 shortens. The maximum moving distance of the sieve plate 501 does not exceed the length of the flap 305. The movement of the sieve plate 501 causes micro-vibration of the straw, so that the sand and gravel in the straw fall from the through holes of the sieve plate 501.

[0026] In order to transport the straw to the straw transport vehicle, a conveyor belt 401 is fixedly arranged on one side of the flap 305, and one end of the conveyor belt 401 is fixedly connected to the output shaft of the motor 402, and the motor 402 is fixedly arranged in the machine body 1. The flap 305 is tilted to make the straw fall onto the conveyor belt 401, and the conveyor belt 401 transports the straw to the straw transport vehicle.

[0027] Working principle of the present invention: First, the device is towed by an agricultural vehicle and pulled onto a straw row, with the ground contacting wheels 101 in contact with the ground.

[0028] Then adjust the distance of the collecting teeth 208 from the ground, loosen the fixing screw 210, and then twist the rotating rod 209 to rotate the rotating rod 209, and the wedge rod 211 rotates accordingly, and the wedge block 212 moves away from the rotating rod 209, and the sleeve rod 207 moves accordingly. At this time, the first spring 214 extends, the first telescopic rod 215 extends, and the sleeve rod 207 drives the collecting teeth 208 connected thereto to move. On the contrary, the first spring 214 shortens, the first telescopic rod 215 shortens, the wedge block 212 moves toward the rotating rod 209, and the sleeve rod 207 and the collecting teeth 208 move accordingly. Secondly, the collecting teeth 208 can also be installed in different positions through the multiple screw holes on the sleeve rod 207, thereby achieving height adjustment or replacement of a single collecting tooth 208.

[0029] The device is pulled forward by the agricultural vehicle, and the switch of the motor 402 is turned on to make the conveyor belt 401 work.

[0030] The grounding wheel 101 rotates the rotating shaft 102, and the rotation of the rotating shaft 102 drives the first pulley 201 to rotate. The kinetic energy of the first pulley 201 is transmitted to the second pulley 203 via the first belt 202, and the second pulley 203 rotates. The second pulley 203 drives the rotating shaft 204 to rotate in the machine body 1. The rotation of the rotating shaft 204 drives the collecting wheel 205 fixedly connected thereto to rotate in the same direction. The bottom mounting rod 206 rotates with the rotation of the collecting wheel 205, and the sleeve rod 207 in the bottom mounting rod 206 rotates accordingly. The sleeve rod 207 and the collecting teeth 208 on the sleeve rod 207 rotate accordingly, and the collecting teeth 208 collect the straw. The rotation of the second pulley 203 drives the third pulley 301 to rotate at the same time, and the third pulley 301 drives the fourth pulley 303 to rotate through the second belt 302, and the toggle rod 304 applies pressure to the surface of the elliptical groove 306, the elliptical groove 306 moves repeatedly, the flap 305 moves repeatedly, and the driven rod 307 also rotates accordingly, and the second spring 308 and the second telescopic rod 309 extend and shorten accordingly. When the toggle rod 304 rotates to the bottom, the flap 305 is horizontal, and the collecting rod 310 at the end of the flap 305 pushes the straw collected on the collecting teeth 208 onto the flap 305. When the toggle rod 304 gradually rotates to the top, the flap 305 gradually tilts, and the straw falls onto the conveyor belt 401. The time required for the adjacent collecting teeth 208 to rotate to the position of the collecting rod 310 is the same as the time required for the toggle rod 304 to rotate one circle. When the collecting teeth 208 rotate to a nearly vertical state, the toggle rod 304 also rotates to a horizontal state and intersects with the toggle rod 304 to complete the toggle of the straw on the collecting teeth 208.

[0031] Finally, the conveyor belt 401 transports the straw to the straw transport vehicle.
