[0060] The two delivery pipes 8 are respectively fixedly connected with the corresponding dust collection boxes 6 , and the two delivery pipes 8 are respectively communicated with the corresponding dust collection boxes 6 .

[0061] Furthermore, the material dividing assembly includes two fixing plates 18, both fixing plates 18 are fixedly connected to the left and right inner walls of the crushing box 1, and the upper surfaces of the two fixing plates 18 are fixedly connected to two second springs 17, and the upper surfaces of the four second springs 17 are fixedly connected to triangular plates 19;

[0062] The lower surface of the triangular plate 19 is fixedly connected to two mounting plates 14 , and the lower surfaces of the two mounting plates 14 are both fixedly mounted with vibration motors 13 .

[0063] Furthermore, the front and rear surfaces of the triangular plate 19 respectively penetrate the inner walls of the corresponding first rectangular grooves 22 , and extend to the interiors of the two installation boxes 5 through the corresponding second rectangular grooves 23 .

[0064] Furthermore, six first springs 15 are fixedly connected to the lower surface of the triangular plate 19, and the lower ends of the six first springs 15 are respectively fixedly connected to the inner walls of the corresponding first rectangular grooves 22;

[0065] Among them, auxiliary telescopic rods are telescopically arranged inside the six first springs 15 and the four second springs 17, and the telescopic ends of the auxiliary telescopic rods are fixedly installed together with the lower surface of the triangular plate 19, and the auxiliary telescopic rods are respectively fixedly installed together with the inner walls of the corresponding first rectangular grooves 22 and the upper surfaces of the two fixed plates 18.

[0066] Furthermore, two feed boxes 7 communicating with the interior of the crushing box 1 are fixedly connected to the upper surface thereof, mounting frames 3 are fixedly connected to the lower surfaces of the two support frames 2, and conveying mechanisms 4 are fixedly connected to the opposite surfaces of the two mounting frames 3.

[0067] Furthermore, when the agricultural and forestry waste crushing and collecting device is used, the second servo motor 26 and the two first servo motors 21 are first started, the second servo motor 26 drives the two second transmission shafts 25 to rotate through the two first gears 24, and the two second transmission shafts 25 drive the first crushing rollers to rotate;

[0068] The two first servo motors 21 drive the four first transmission shafts 16 to rotate through the four second gears 27, and the four first transmission shafts 16 drive the four crushing rollers to rotate;

[0069] Then, the straw is put into the crushing box 1 through two feeding boxes 7, and the straw falls on the two inclined plates 11, and falls on the two fast-rotating first crushing rollers along the inclined surfaces of the two inclined plates 11;

[0070] The two first crushing rollers crush the straw for the first time, and the crushed straw falls onto the triangular plate 19;

[0071] Among them, two vibration motors 13 are started at the same time, and adjustable eccentric blocks are installed at both ends of the rotor shafts of the two vibration motors 13. When the motors are powered on and rotate, the center of mass of the eccentric blocks deviates from the axis of rotation, generating periodic centrifugal force. After the centrifugal force in the horizontal and vertical directions is synthesized, an exciting force is formed. The exciting force is transmitted to the mounting plate 14 through the motor base, causing the mounting plate 14 to vibrate slightly. The vibration of the mounting plate 14 is transmitted to the triangular plate 19 through the spring elastic system (the second spring 17 and the first spring 15). The functions of the springs are: amplifying the amplitude: by adjusting the matching relationship between the spring stiffness and the exciting frequency, the triangular plate 19 resonates, and the amplitude can reach 3-5 times the amplitude of the motor; stabilizing the vibration direction: the second spring 17 (connecting the fixed plate 18 and the triangular plate 19) and the first spring 15 (connecting the triangular plate 19 and the inner wall of the crushing box) form a three-dimensional elastic support to ensure that the triangular plate 19 vibrates in the vertical direction to avoid lateral displacement.

[0072] The vibrating triangular plate 19 not only diverts the first crushed straw, thereby reducing the pressure of the next crushing, but also drives the first crushed straw to move through vibration, thereby increasing the feeding speed to prevent blockage, and can also vibrate out the dust on the first crushed straw;

[0073] The two dust suction pumps 9 are started at the same time, and the two dust suction pumps 9 suck the floating dust and impurities in the crushing box 1 into the dust collecting box 10 through the two conveying pipes 8 and the two dust suction boxes 6, and then the inside of the crushing box 1 is dusted to prevent a large amount of dust and impurities from polluting the air, thereby improving the environmental protection of the agricultural and forestry waste crushing and collecting device;

[0074] The straw that has been crushed for the first time goes along the inclined surface of the triangular plate 19 through the inner walls of the two first rectangular grooves 22 and the two second rectangular grooves 23 into the interior of the two installation boxes 5, and is crushed for the second time by four crushing rollers;

[0075] Among them, by setting the crushing component, the straw can be crushed twice, the first time is preliminary crushing, and the second time can crush the straw that is not crushed thoroughly enough in the first time, thereby improving the crushing quality, and also eliminating the need to use a sieve plate to screen it, then collect it, and then crush it, thereby reducing the crushing time and improving the crushing efficiency;

[0076] The completely crushed straw will fall into the conveying mechanism 4 through the two discharge boxes 12, and then the conveying mechanism 4 is started to drive the completely crushed straw to move, thereby facilitating the collection of the completely crushed straw.
