A feeding port 5 is provided on one side of the forage mixing bin 1. The main conveying screw 2, the first conveying screw 3 and the second conveying screw 4 are all rotatably connected inside the forage mixing bin 1. The main conveying screw 2 is located below the first conveying screw 3 and the second conveying screw 4.

[0038] The internal rotation of the forage mixing bin 1 is connected with an auxiliary pushing structure, which is located above the first conveying screw 3 and the second conveying screw 4. The side of the forage mixing bin 1 away from the feed inlet 5 is connected with a discharge bin 6, and a discharge port 7 is provided on one side of the discharge bin 6. A baffle 8 is detachably provided on the side of the discharge bin 6 away from the forage mixing bin 1, and a control structure for controlling the rotation of the first conveying screw 3 and the second conveying screw 4 is provided on one side of the baffle 8. Specifically, the grass bale is fed into the forage mixing bin 1 through the feed inlet 5 and falls between the first conveying screw 3 and the second conveying screw 4;

[0039] Furthermore, during rotation, the spiral blades on the first conveying screw 3 push the bale toward the direction close to the discharge bin 6, such as Figure 3As shown, the thread path of the second conveying screw 4 is opposite to the thread path of the first conveying screw 3, and the first conveying screw 3 and the second conveying screw 4 are on the same horizontal line. When rotating, the second conveying screw 4 pushes the grass bale in the direction away from the discharge bin 6, and then tears the bottom of the grass bale between the first conveying screw 3 and the second conveying screw 4. The first conveying screw 3 and the second conveying screw 4 are both provided with a first blade 27. In the process of tearing the grass bale, the bottom of the grass bale can also be cut by the first blade 27, so as to speed up the separation efficiency of the grass bale. The cut and separated grass will fall onto the main conveying screw 2, and the separated grass will be transported to the discharge bin 6 by the main conveying screw 2.

[0040] During the tearing process of the straw bale, the straw bale will deviate to the side. The auxiliary pushing structure includes two groups of rollers 9, and both groups of rollers 9 are rotatably connected to the straw mixing bin 1. The first conveying screw 3 and the second conveying screw 4 are located between the two groups of rollers 9. Both groups of rollers 9 are provided with multiple groups of pushing rods 10. During the rotation of the two groups of rollers 9, the set pushing rods 10 can push the deviated straw bale inward, so that the straw bale is always kept between the first conveying screw 3 and the second conveying screw 4.

[0041] Furthermore, the auxiliary pushing structure includes a third conveying screw 11 and a fourth conveying screw 12, the third conveying screw 11 and the fourth conveying screw 12 are located above the two sets of rollers 9 and are both rotatably connected to the forage mixing bin 1;

[0042] The thread path of the third conveying screw 11 is the same as the thread path of the first conveying screw 3 , and the thread path of the fourth conveying screw 12 is the same as the thread path of the second conveying screw 4 ;

[0043] The third conveying screw 11 and the fourth conveying screw 12 are both provided with a second blade 28. Specifically, when the first conveying screw 3 and the second conveying screw 4 are tearing the bottom of the bale, when the bale deviates to one side, the third conveying screw 11 and the second blade 28 on the fourth conveying screw 12 above the pushing rod 10 can cut the top of the bale during the pushing process, thereby further accelerating the separation efficiency of the bale. When the top of the bale is cut, part of the grass will fall below the roller 9 along the roller 9. During the rotation of the roller 9, the pushing rod 10 can push the grass below the roller 9 to the main conveying screw 2 to prevent the grass from accumulating in the grass mixing bin 1.

[0044] Further, such as Figure 2 and Figure 3As shown, the main conveying screw 2, the first conveying screw 3, the second conveying screw 4, the third conveying screw 11, the fourth conveying screw 12 and the same end of the two sets of rollers 9 all pass through the forage mixing bin 1 and the discharging bin 6 and are rotatably connected to the baffle 8;

[0046] The fourth conveying screw 12 and the second conveying screw 4 are both connected to the roller 9 close to the second conveying screw 4 through the second transmission belt 14 .

[0047] Further, such as Figure 4 As shown, the control structure includes a main driving gear 15, a first auxiliary driving gear 16 and a second auxiliary driving gear 17. The main conveying screw 2 is fixedly connected to the main driving gear 15, and the first conveying screw 3 and the second conveying screw 4 are fixedly connected to the first auxiliary driving gear 16 and the second auxiliary driving gear 17 respectively. The first auxiliary driving gear 16 is meshed with the main driving gear 15. Figure 5 As shown, a positioning shaft 18 is provided on one side of the baffle 8 close to the discharge bin 6, and a direction-changing gear 19 is rotatably connected to the positioning shaft 18. Figure 4 As shown, the direction changing gear 19 is located between the main driving gear 15 and the second auxiliary driving gear 17 , and the direction changing gear 19 is meshedly connected with the main driving gear 15 and the second auxiliary driving gear 17 .

[0048] Further, such as Figure 4 As shown, the discharge bin 6 is internally rotatably connected with a rotating shaft 21 , which is located below the main conveying screw 2 . The rotating shaft 21 is at least one group, and a plurality of groups of shifting sleeve rods 22 are sleeved on the rotating shaft 21 .

[0049] Further, such as Figure 2 As shown, the control structure also includes a drive motor 23 , and a motor support seat 24 is fixedly connected to the side of the baffle 8 away from the discharge bin 6 . The drive motor 23 is installed on the motor support seat 24 , and the output shaft of the drive motor 23 is fixedly connected to the main conveying screw 2 .

[0050] Specifically, the driving motor 23 drives the main conveying screw 2 to rotate clockwise through the output shaft, so that the cut grass is transported to the discharge bin 6 through the main conveying screw 2, and the main conveying screw 2 drives the main driving gear 15 to rotate clockwise, and under the meshing action of the first auxiliary driving gear 16 and the main driving gear 15, drives the first conveying screw 3 to rotate counterclockwise, and under the action of the first transmission belt 13, the roller 9 and the third conveying screw 11 close to one side of the first conveying screw 3 will rotate in the same direction with the first conveying screw 3, thereby cutting one side of the grass bale and assisting in pushing;

[0051] Furthermore, during the clockwise rotation of the main drive gear 15, the changing gear 19 rotates counterclockwise under the meshing action of the changing gear 19 and the main drive gear 15, and the second sub-drive gear 17 rotates clockwise under the meshing action of the changing gear 19 and the second sub-drive gear 17, thereby causing the second conveying screw 4 to rotate clockwise. Under the action of the second transmission belt 14, the roller 9 and the fourth conveying screw 12 close to one side of the second conveying screw 4 will rotate in the same direction as the second conveying screw 4, thereby cutting the other side of the bale and assisting in pushing.

[0052] Further, such as Figure 2 and Figure 4 As shown, two groups of rotating shafts 21 are provided, and one end of the two groups of rotating shafts 21 away from the discharge bin 6 passes through the baffle 8 and extends outward, and is connected by a third transmission belt 25. The installation allows the rotating shaft 21 to be installed according to the distance between the discharge port 7 and the main conveying screw 2, so that the rotating shaft 21 can send the grass from the discharge port 7 by driving the sleeve rod 22. The main conveying screw 2 is connected to one of the rotating shafts 21 by a fourth transmission belt 26. The cut and separated grass will fall onto the main conveying screw 2, and the separated grass will be transported to the discharge bin 6 through the main conveying screw 2. When the driving motor 23 drives the main conveying screw 2 to rotate clockwise through the output shaft, the rotating shaft 21 and the toggle sleeve rod 22 on the rotating shaft 21 are driven to rotate clockwise under the action of the third transmission belt 25, and then the grass in the discharge bin 6 is sent out from the discharge port 7 for livestock use.

[0053] Embodiment 2

[0054] This embodiment is improved on the basis of the first embodiment as follows: Figure 4 As shown, threaded docking holes are provided on the discharge bin 6 and the baffle 8, and the threaded docking holes are threadedly connected with docking bolts 20. The discharge bin 6 and the baffle 8 are fixedly connected by the docking bolts 20, so that the staff can inspect and repair the discharge bin 6.

[0055] In summary, the workflow of the utility model is:

[0056] The driving motor 23 drives the main conveying screw 2 to rotate clockwise through the output shaft, so that the cut grass is transported to the discharge bin 6 through the main conveying screw 2. The main conveying screw 2 drives the main driving gear 15 to rotate clockwise, and under the meshing action of the first auxiliary driving gear 16 and the main driving gear 15, the first conveying screw 3 is driven to rotate counterclockwise. Under the action of the first transmission belt 13, the roller 9 and the third conveying screw 11 close to one side of the first conveying screw 3 will rotate in the same direction as the first conveying screw 3;

[0057] Furthermore, during the clockwise rotation of the main driving gear 15, the direction-changing gear 19 rotates counterclockwise under the meshing action of the direction-changing gear 19 and the main driving gear 15, and the second sub-driving gear 17 rotates clockwise under the meshing action of the direction-changing gear 19 and the second sub-driving gear 17, thereby causing the second conveying screw 4 to rotate clockwise. Under the action of the second transmission belt 14, the roller 9 and the fourth conveying screw 12 close to one side of the second conveying screw 4 rotate in the same direction as the second conveying screw 4.

[0058] During rotation, the spiral blades on the first conveying screw 3 push the bale in the direction close to the discharge bin 6, and the second conveying screw 4 pushes the bale in the direction away from the discharge bin 6, thereby tearing the bottom of the bale between the first conveying screw 3 and the second conveying screw 4, and at the same time cutting the bottom of the bale by the first blade 27. During the rotation of the two sets of rollers 9, the set pushing rod 10 can push the sideways bale inward, so that the bale is always kept between the first conveying screw 3 and the second conveying screw 4. During the pushing process of the pushing rod 10, the third conveying screw 11 above the pushing rod 10 and the second blade 28 on the fourth conveying screw 12 can cut the top of the bale, thereby further accelerating the separation efficiency of the bales.

[0059] The cut and separated grass will fall onto the main conveying screw 2, and the separated grass will be conveyed to the discharge bin 6 through the main conveying screw 2. When the driving motor 23 drives the main conveying screw 2 to rotate clockwise through the output shaft, the third transmission belt 25 drives the rotating shaft 21 and the driving sleeve rod 22 on the rotating shaft 21 to rotate clockwise, thereby delivering the grass in the discharge bin 6 from the discharge port 7 for livestock use.
