By arranging the box cover 4 on the crushing box 3, on the one hand, the operating safety can be improved, and on the other hand, the dispersion of forage dust can be prevented.

[0026] A driving mechanism is provided on one side of the screening box 2 and the crushing box 3, and the driving mechanism includes a driving motor 5 installed on one side of the crushing box 3. The output end of the driving motor 5 is provided with a first transmission belt 6 connected to the first driving shaft 15, and the first driving shaft 15 is connected to the second driving shaft 11 through a second transmission belt 7. The output end of the driving motor 5 is provided with a first transmission pulley A19, one of the two sets of first driving shafts 15 is provided with a first transmission pulley B20, and the first transmission pulley A19 is connected to the first transmission pulley B20 through the first transmission belt 6, and the other set of the two sets of first driving shafts 15 is provided with a second transmission pulley A21. The shaft rod of the shaft 11 is provided with a second transmission pulley B22, and the second transmission pulley A21 and the second transmission pulley B22 are connected by the second transmission belt 7. When the forage crushing device is used to crush the forage, the drive motor 5 is controlled to work as the driving source, and the transmission combination of the first transmission pulley A19, the first transmission belt 6, and the first transmission pulley B20 is used to drive the first drive shaft 15 to rotate. While the first drive shaft 15 is rotating, the transmission combination of the second transmission pulley A21, the second transmission belt 7, and the second transmission pulley B22 is used to drive the second drive shaft 11 to rotate, and then drive the components on the two sets of drive shafts to operate, so as to perform double cutting and crushing work on the forage.

[0027] A crushing mechanism is arranged inside the crushing box 3, and the crushing mechanism includes a first driving shaft 15 symmetrically arranged inside the crushing box 3 and roller teeth 9 symmetrically arranged on the wall of the crushing box 3. Crushing rollers 8 staggered with the roller teeth 9 are symmetrically arranged on the outer side of the shaft of the first driving shaft 15. Mutually mating gears 16 are arranged at one end of the shafts of the two groups of first driving shafts 15. The first driving shaft 15 maintains symmetrical rotation under the symmetrical meshing transmission of the mating gears 16, and then drives the crushing rollers 8 to rotate symmetrically, so as to perform mating crushing on the grass in the crushing box 3.

[0028] The upper half of the screening box 2 is provided with a rotary cutting and screening mechanism, which includes a filter screen cylinder 10 installed on the upper half of the screening box 2 and a second driving shaft 11 installed in the middle of the sleeve of the filter screen cylinder 10. One side of the shaft of the second driving shaft 11 is provided with multiple groups of cutting blades 17 arranged at equal intervals, and the other side of the shaft of the second driving shaft 11 is provided with a bottom scraper 18. The blade head of the cutting blade 17 and the bottom plate of the bottom scraper 18 are both in contact with the cylinder wall of the filter screen cylinder 10. During the rotation of the second driving shaft 11, the cutting blade 17 and the bottom scraper 18 are driven to rotate synchronously. The cyclic rotary cutting of the cutting blade 17 is used to rotary cut and crush the grass in the filter screen cylinder 10 again, so that the qualified grass is filtered and screened out by the filter screen cylinder 10. At the same time, the cyclic scraping of the bottom scraper 18 is used to circulate the grass in the filter screen cylinder 10 to shake the grass, which is convenient for the dropping of grass.

[0029] The lower half of the screening box 2 is provided with a vibrating screening mechanism, which includes vibration springs 14 symmetrically installed in pairs on the upper ends of the support legs 1, and a screening mesh plate 13 penetrating the lower half of the crushing box 3 is installed on the top of the spring seat of the vibration spring 14, and a vibration motor 12 is installed in the middle of the plate surface of the screening mesh plate 13. When the crushed grass falls onto the screening mesh plate 13, the vibration motor 12 is controlled to work, and the screening mesh plate 13 is driven to vibrate mechanically under the support of the elastic force of the vibration spring 14, so as to vibrate and screen the grass, and screen out qualified and unqualified grass.

[0030] The working principle of the utility model is as follows: when the forage crushing device is used to crush the forage, the forage is put into the crushing box 3, and the box cover 4 is closed, and then the driving motor 5 is controlled to work as the driving source, and the transmission combination of the first transmission pulley A19, the first transmission belt 6, and the first transmission pulley B20 is used to drive the first driving shaft 15 to rotate. While the first driving shaft 15 rotates, the transmission combination of the second transmission pulley A21, the second transmission belt 7, and the second transmission pulley B22 is used to drive the second driving shaft 11 to rotate synchronously. Furthermore, the first driving shaft 15 maintains symmetrical rotation under the symmetrical meshing transmission of the matching gears 16, and then drives the crushing rollers 8 to rotate symmetrically, so as to perform matching crushing on the forage in the crushing box 3, and the preliminarily crushed forage is circulated and falls into the filter screen The drum 10 and the second driving shaft 11 drive the slitting blade 17 and the bottom scraper 18 to rotate synchronously during the rotation process. The slitting blade 17 is used for cyclic peeling to peel and crush the grass in the filter screen drum 10 again, so that the qualified grass is filtered and screened out by the filter screen drum 10. At the same time, the grass in the filter screen drum 10 is cyclically scraped and shaken by the bottom scraper 18 to facilitate the dropping of the grass. Then the crushed grass falls onto the screening mesh plate 13, and the vibration motor 12 is controlled to work. Under the support of the elastic force of the vibration spring 14, the screening mesh plate 13 is driven to vibrate mechanically, and the grass is vibrated and screened, and the qualified and unqualified grass are screened out. The subsequent staff will collect the qualified grass and put the unqualified grass into the crushing device again for crushing.
