As shown in fig. 1 to 6.

The utility model provides a rice straw cutter, which comprises a bracket 1 and a conveying belt 2 arranged on the inner side of the bracket 1 through rotating shafts arranged at two ends, and is characterized in that: the utility model discloses a novel rice straw cutting machine, including support 1, mounting bracket 1, cylinder 61, cutter 62 that the lower surface fixed mounting of mounting bracket 6 has, and the rotatory driving motor 3 of drive pivot is installed to one end of support 1 lateral surface, the one end of support 1 upper surface is through bolt fixed mounting to have a guide division board 4, and guide division board 4 can separate a plurality of rice straw and handle, prevents to take place the adhesion between the rice straw, the top of support 1 and be located one side of guide division board 4 have two height-adjustable flush rollers 5 through "U" support frame 51 fixed mounting, and two flush rollers 5 can play the effect of double extrusion to the rice straw, can be with the straw of extruder yardstick to prevent not doing the straw that cuts and stretch out and draw back backward, can cut neatly when making the cutting, the other end welding of support 1 upper surface has mounting bracket 6, the intermediate position of mounting bracket 6 upper surface has cylinder 61 through bolt fixed mounting, cutter 62 that is connected with cylinder 61 transmission.

The two ends of the guide division plate 4 are provided with fixing plates 41 fixed above the support 1 through bolts, a plurality of semicircular guide cylinders 42 are fixedly arranged between the two fixing plates 41, the number of the guide cylinders 42 is especially 6-8, the lower ends of two adjacent sides of the guide cylinders 42 are respectively welded and fixedly provided with the upper surfaces of the division teeth 43, the number of the division teeth 43 is smaller than one of the number of the guide cylinders 42, the shape of the division teeth 43 is formed by combining a rectangle and a triangle, the triangle is positioned at one end of feeding, the guiding effect can be achieved, and the rice straw can be smoothly divided.

The lower extreme of two lateral surfaces of support 1 is respectively through bolt fixed mounting there being two mounts 8, is located two of same flush roller 5 below equal movable mounting has pivot 7 between the mount 8, two the one end of pivot 7 with one side just is located the outside of mount 8 and all installs the crank 72 that is used for the staff to grasp rotatory, and the crank 72 can drive pivot 7 rotation, two the both ends of pivot 7 just are located the inboard of mount 8 and all fixed mounting have worm 71, support frame 51 welded fastening is at the upper surface of support 1, four the equal movable mounting of inside of support frame 51 has connecting axle 52, four the upper end of connecting axle 52 all runs through support frame 51 and flush roller 5, four worm wheel 52 all respectively with the one end threaded connection of flush roller 5, four the lower extreme fixed mounting of connecting axle 52 has the 53 that meshes with worm 71, and the rotatory accessible worm 71 of pivot 7 drives 53 and rotate, and can drive pivot 5 through connecting axle 52 and rise or move down, and two other worm wheel 7 accessible are rotatory control of crank 72 can make two individual height control flush roller 5.

A sliding groove 54 for sliding the fastening bolt 55 up and down is formed on one side surface of the supporting frame 51 on the same side, and the fastening bolt 55 can fix the flush roller 5.

The parallel roller 5 positioned on one side of the mounting frame 6 is closer to the mounting frame 6, and is 3-5 cm in length, so that the cutter 62 below the mounting frame 6 can smoothly cut the rice straw.

Firstly, according to the use requirement of the rice straw, the heights of the two flush rollers 5 are respectively adjusted, firstly, the fastening bolt 55 is rotated anticlockwise, so that the fastening bolt 55 loosens the flush rollers 5, then a worker firstly holds the crank 72 by hand, then rotates the crank 72, then the crank 72 drives the rotating shaft 7 to rotate, then the rotating shaft drives the worm 71 to rotate, the worm 71 is clamped with the worm wheel 53, then the worm 71 drives the worm wheel 53 to rotate, the worm wheel 53 drives the connecting shaft 52 to rotate, and further, due to the threaded connection between the connecting shaft 52 and the flush rollers 5, the connecting shaft 52 drives the flush rollers 5 to rotate to move upwards or downwards, after the flush rollers 5 move to a proper position, the worker puts down the crank 72, then rotates the fastening bolt 55 clockwise, so that the fastening bolt 55 clamps and fixes the flush rollers 5, the flush rollers 5 are prevented from accidentally sliding, after the positions of the two flush rollers 5 are adjusted, then the conveyor belt 2 is started, each rice straw at one end on the conveyor belt 2 is guided by the dividing teeth 43 to independently pass through the guide cylinder 42, the separation treatment is carried out through the guide dividing plate 4 to prevent the rice straws from being adhered together, then the separated rice straws are driven by the conveyor belt 2 to sequentially pass through the lower parts of the two parallel and level rollers 5 to move to the lower part of the mounting frame 6, the two parallel and level rollers 5 can better squeeze the rice straws to enable the rice straws to be aligned, the parallel and level rollers 5 close to the mounting frame 6 can better enable the cutter 62 to cut the rice straws, when the rice straws are moved to a proper position below the mounting frame 6, then the conveyor belt 2 stops running, then the cylinder 61 stretches to push the straight cutter 62 to stretch downwards to directly cut one end of the rice straws, the interval time between two stretching of the air cylinder 61 can be adjusted according to the length of the rice straw to be cut, when the straight cutter 62 finishes cutting the rice straw, the flush roller 5 still extrudes the straw which is not cut at the moment, the straw which is not cut is prevented from stretching backward, then the air cylinder 61 contracts and pulls the straight cutter 62 to shrink upward until the straight cutter 62 is restored to the original position, then the conveyor belt 2 continues to run, the rice straw above is driven to continue to move, the cut rice straw moves out from the lower part of the mounting frame 6 to the other end of the conveyor belt 2, next link equipment is entered, then the straw which is not cut at the rear is moved to the lower part of the mounting frame 6, the steps above are repeated, and the rice straw to be cut is continuously cut by the straight cutter 62.

By utilizing the technical scheme of the utility model or under the inspired by the technical scheme of the utility model, a similar technical scheme is designed by a person skilled in the art, so that the technical effects are achieved, and the technical scheme falls into the protection scope of the utility model.
