[0011] Preferably, the method for using the waste straw crushing device comprises the following steps:

[0012] S1: When the waste straw is crushed, an equal amount of the waste straw is put into the crushing box, and then the driving motor drives the transmission rod to rotate. When the transmission rod rotates, the first connecting frame is driven to rotate. The first connecting frame can drive the second connecting frame to rotate through a cross connecting rod. An elastically retractable clamping frame is arranged between the two connecting members, so that when the transmission rod rotates, the first connecting frame arranged on the support plate can be driven to rotate. Through this arrangement, when the support plate slides on the side wall of the processing table to adjust its position, the first connecting frame arranged on the support plate can still be rotated;

[0013] S2: When the driving motor drives the transmission rod to rotate, the transmission rod drives the first bevel gear to rotate, and the first bevel gear drives the second bevel gear to make the rotating rod rotate synchronously. When the rotating rod rotates, the rotating rod drives the rotating frame to rotate, and the rotating frame pulls the connecting rod to make the sliding rod reciprocate in the slide groove on the processing table, and the first rack is fixedly connected to the side wall of the processing table, and the second rack is fixedly connected to the support plate. Then, when the sliding rod moves, the transmission gear makes the second rack slide on the side wall of the processing table under the restriction of the first rack. At this time, the second rack drives the support plate to move from the top of the crushing box toward the bottom of the crushing box, so that the crushing assembly arranged on the support plate can press the waste straw in the crushing box to the bottom of the crushing box;

[0014] S3: When the waste straw is in the crushing box, the driving motor drives the transmission rod to rotate, and the two connecting members drive the driving rod arranged on the support plate to rotate. When the driving rod rotates, the sleeve rod arranged on the driving rod will be driven to rotate synchronously. The synchronous rotation of the driving rod and the sleeve rod can make the first crushing blade and the second crushing blade rotate synchronously in the crushing box, so that the waste straw in the crushing box can be subjected to rotary crushing operation;

[0015] S4: When the support plate drives the crushing assembly to move down to the bottom of the crushing box, the pressure rod arranged on the processing table will contact the end face of the wedge-shaped block on the support plate. At this time, the pressure rod will squeeze the wedge-shaped block, and the wedge-shaped end of the wedge-shaped block will contact the end face of the clamping tube, so that the clamping tube gradually moves toward the direction where the first crushing blade is provided on the driving rod and clamps with the driving rod. At this time, the clamping tube rotates under the drive of the driving rod, and the rotation of the clamping tube cooperates with the double helix provided on its outer wall and the limit frame, so that the limit plate can be driven to reciprocate on the two limit rods. When the limit plate moves back and forth, the adjusting frame is driven by the two adjusting rods to move the sleeve rod on the driving rod. At this time, the second crushing blade provided on the sleeve rod will move in the crushing box. The reciprocating movement of the sleeve rod can prevent part of the waste straw from being entangled on the driving rod and the main shaft of the sleeve rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the present invention, when the waste straw is crushed, an equal amount of the waste straw is put into the crushing box, and then the driving motor drives the transmission rod to rotate. When the transmission rod rotates, it drives the first connecting frame to rotate. The first connecting frame can drive the second connecting frame to rotate through a cross connecting rod. An elastically retractable clamping frame is arranged between the two connecting parts, so that when the transmission rod rotates, it can drive the first connecting frame arranged on the support plate to rotate. Through this arrangement, when the support plate slides on the side wall of the processing table to adjust its position, the first connecting frame arranged on the support plate can still be rotated, so as to facilitate the continuous crushing operation of the straw in the crushing box.

[0018] When the driving motor drives the transmission rod to rotate, the transmission rod drives the first bevel gear to rotate, and the first bevel gear drives the second bevel gear to make the rotating rod rotate synchronously. When the rotating rod rotates, the rotating rod drives the rotating frame to rotate, and the rotating frame pulls the connecting rod to make the sliding rod reciprocate in the sliding groove on the processing table, and the first rack is fixedly connected to the side wall of the processing table, and the second rack is fixedly connected to the supporting plate. Then, when the sliding rod moves, the transmission gear makes the second rack slide on the side wall of the processing table under the restriction of the first rack. At this time, the second rack drives the supporting plate to move from the top of the crushing box toward the bottom of the crushing box, so that the crushing assembly arranged on the supporting plate can press the waste straw in the crushing box to the bottom of the crushing box, so that the crushed straw can be squeezed and crushed more effectively, and the transmission gear can drive the travel distance of the second rack to be extended when it rotates, so that the support plate can drive the crushing assembly to move a longer distance toward the crushing box to achieve a better crushing effect.

[0019] In the present invention, when the waste straw is in the crushing box, the transmission rod is driven to rotate by the driving motor, and the driving rod arranged on the support plate is driven by the two connecting parts to rotate. When the driving rod rotates, the sleeve rod arranged on the driving rod is driven to rotate synchronously. The synchronous rotation of the driving rod and the sleeve rod can make the first crushing blade and the second crushing blade rotate synchronously in the crushing box, and the waste straw in the crushing box can be rotationally crushed. The support plate will continue to move toward the bottom of the crushing box driven by the stroke component, and can gradually squeeze the straw in the crushing box to the bottom of the crushing box, so that the straw crushing effect is better.

[0020] When the support plate drives the crushing assembly to move downward to the bottom of the crushing box, the pressure rod arranged on the processing table will contact the end face of the wedge-shaped block on the support plate. At this time, the pressure rod will squeeze the wedge-shaped block, and the wedge-shaped end of the wedge-shaped block will conflict with the end face of the clamping tube, so that the clamping tube gradually moves toward the direction where the driving rod is provided with the first crushing blade and clamps with the driving rod. At this time, the clamping tube rotates under the drive of the driving rod, and the rotation of the clamping tube cooperates with the double helix arranged on its outer wall and the limit frame, so that the limit plate can be driven to reciprocate on the two limit rods. When the limit plate reciprocates, the adjusting frame is driven by the two adjusting rods to make the sleeve rod move on the driving rod. At this time, the second crushing blade arranged on the sleeve rod will move in the crushing box, and the reciprocating movement of the sleeve rod can prevent part of the waste straw from being entangled around the main shaft of the driving rod and the sleeve rod, thereby more effectively crushing the waste straw.

5. The method for using the waste straw pulverizing device according to claim 4 comprises the following steps: S1: When waste straw is crushed, an equal amount of waste straw is placed in the crushing box (11), and then the driving motor (31) drives the transmission rod (32) to rotate. When the transmission rod (32) rotates, it drives the first connecting frame (41) to rotate. The first connecting frame (41) can drive the second connecting frame (42) to rotate through the cross connecting rod (43). An elastically retractable clamping frame (44) is arranged between the two connecting members (4), so that when the transmission rod (32) rotates, the first connecting frame (41) arranged on the support plate (33) can be driven to rotate. Through this arrangement, when the support plate (33) slides on the side wall of the processing table (1) to adjust its position, the first connecting frame (41) arranged on the support plate (33) can still be rotated; S2: When the driving motor (31) drives the transmission rod (32) to rotate, the transmission rod (32) drives the first bevel gear (51) to rotate, and the first bevel gear (51) drives the second bevel gear (53) to make the rotating rod (52) rotate synchronously. When the rotating rod (52) rotates, the rotating rod (52) drives the rotating frame (56) to rotate, and the rotating frame (56) pulls the connecting rod (57) to make the sliding rod (54) reciprocate in the sliding groove (12) on the processing table (1), and the first rack (58) is fixedly connected to the side wall of the processing table (1). The second rack (59) is fixedly connected to the support plate (33), and when the sliding rod (54) moves, the transmission gear (55) causes the second rack (59) to slide on the side wall of the processing table (1) under the restriction of the first rack (58). At this time, the second rack (59) drives the support plate (33) to move from the top of the crushing box (11) toward the bottom of the crushing box (11), thereby facilitating the crushing assembly (6) arranged on the support plate (33) to press the waste straw in the crushing box (11) down to the bottom of the crushing box (11); S3: When the waste straw is in the crushing box (11), the driving motor (31) drives the transmission rod (32) to rotate, and the two connecting members (4) drive the driving rod (63) arranged on the support plate (33) to rotate. When the driving rod (63) rotates, the sleeve rod (65) sleeved on the driving rod (63) is driven to rotate synchronously. The driving rod (63) and the sleeve rod (65) rotate synchronously, so that the first crushing blade (64) and the second crushing blade (66) can be rotated synchronously in the crushing box (11), so that the waste straw in the crushing box (11) can be subjected to a rotary crushing operation; S4: When the support plate (33) drives the crushing assembly (6) to move down to the bottom of the crushing box (11), the pressure rod (617) arranged on the processing table (1) will contact the end surface of the wedge-shaped block (615) on the support plate (33). At this time, the pressure rod (617) will squeeze the wedge-shaped block (615), and the wedge-shaped end of the wedge-shaped block (615) will contact the end surface of the clamping tube (611), so that the clamping tube (611) gradually moves toward the direction where the first crushing blade (64) is provided on the driving rod (63) and is clamped with the driving rod (63). At this time, the clamping tube (611) is driven by the driving rod (63) to move. The clamping tube (611) rotates and cooperates with the double helix (612) provided on its outer wall and the limiting frame (613), thereby driving the limiting plate (67) to move back and forth on the two limiting rods (62). When the limiting plate (67) moves back and forth, the adjusting frame (610) is driven by the two adjusting rods (69) to move the sleeve rod (65) on the driving rod (63). At this time, the second crushing blade (66) provided on the sleeve rod (65) moves in the crushing box (11). The reciprocating movement of the sleeve rod (65) can prevent part of the waste straw from being entangled on the main shaft of the driving rod (63) and the sleeve rod (65).
