[0035] The frame 1 is the main structure of the straw recycling baler, and plays a role in fixing and supporting other units;

[0036] The pickup bin 2 is arranged at the bottom of the frame 1 and an opening for straw to enter is provided at the front end thereof, and the straw can enter the interior of the pickup bin 2 through this opening;

[0037] The picking and crushing unit 3 is arranged inside the picking bin 2. The picking and crushing unit 3 can crush and rub the straw inside the picking bin 2 to form forage;

[0038] The first conveying unit 4 is respectively arranged inside the picking bin 2 and on top of the temporary storage unit 5 and can connect the picking bin 2 and the temporary storage unit 5. The first conveying unit 4 can convey the forage inside the picking bin 2 to the temporary storage unit 5;

[0039] The temporary storage unit 5 is arranged on the frame 1. The temporary storage unit 5 can temporarily store the forage conveyed by the first conveying unit 4, effectively realizing the allocation of forage;

[0040] The second conveying unit 6 is arranged on the frame 1 and is located below the temporary storage unit 5. The end of the second conveying unit 6 extends into the packing bin 7. The temporary storage unit 5 can drop the forage onto the second conveying unit 6, and the second conveying unit 6 can convey the forage to the packing bin 7;

[0041] The packing bin 7 is arranged at the rear of the frame 1. The packing bin 7 can collect the forage conveyed by the second conveying unit 6;

[0042] The packing unit 8 is arranged inside the packing bin 7. The packing unit 8 can carry out net laying, net winding and net cutting on the forage conveyed by the second conveying unit 6 to form a forage bale packed into a net. The bale discharging unit 9 is arranged at the rear of the packing bin 7. The bale discharging unit 9 can discharge the forage bale so that the forage bale falls to the external ground.

[0043] The straw recycling and packing machine mentioned in this embodiment is equipped with a temporary storage unit 5, which can temporarily store the forage conveyed by its previous process. While the packing unit 8 and the bale discharging unit 9 are carrying out net laying, net cutting and bale discharging, the picking and crushing unit 3 can continuously crush and rub the straw, and the first conveying unit 4 can continuously convey the forage to the temporary storage unit 5.

[0044] When the packing unit 8 is packing and the bale discharging unit 9 is discharging bales, only the second conveying unit 6 needs to be stopped. The main body of the straw recycling and packing machine can ensure non-stop operation. After waiting for the bale discharging unit 9 to complete bale discharging, the second conveying unit 6 can be selected to be started again. The forage in the temporary storage unit 5 is conveyed to the inside of the packing bin 7 through the second conveying unit 6. When the forage inside the packing bin 7 reaches the requirement, the packing unit 8 starts to carry out another packing procedure, and at the same time the second conveying unit 6 pauses. Repeating the above operations can realize one packing cycle after another. The second conveying unit 6 and the packing unit 8 can cooperate with each other to form a periodic packing operation.

[0045] The straw recycling baler can be unaffected by whether the processes of the subsequent units after the temporary storage unit 5 are periodically suspended, thereby obtaining a buffer in operation time for the next baling cycle, ensuring that the units before the temporary storage unit 5 can always maintain continuous operation, and the front main vehicle connected to the baler does not need to stop and wait, and can always move forward, greatly improving the baling efficiency, reducing energy consumption, lowering the forage cost, and having a relatively high degree of automation.
