[0043] In one of the embodiments, the forklift frame assembly 5 is further included, the forklift frame assembly 5 comprises a connecting frame 51, a round rod 52, a pair of fork rods 53 and a third driving member 54, the connecting frame 51 is used to connect the forklift, a pair of screw grooves 521 are oppositely formed on the surface of the round rod 52, and the screw directions of the pair of screw grooves 521 are opposite, the two ends of the round rod 52 are rotatably connected with the connecting frame 51, the pair of fork rods 53 are threadedly connected with the pair of screw grooves 521 in one-to-one correspondence, and the third driving member 54 is in transmission connection with the round rod 52, and the third driving member 54 is used to drive the round rod 52 to rotate and in turn drive the pair of fork rods 53 to move away from or towards each other.

[0044] In the embodiment, the third driving member 54 adopts a servo motor and is electrically connected with a standby storage battery on the forklift, and through the specially-made forklift frame assembly 5, it is convenient to transfer the round straw bundle, in the state that the arc surface of the round straw bundle contacts the ground, the two fork rods 53 first move away from each other, then move towards each other after being inserted into the bottom of the two sides of the round straw bundle, and finally contact the bottom of the round straw bundle, the forklift drives the connecting frame 51 to rise, so that the two fork rods 53 carry the round straw bundle to rise together, that is, the round straw bundle is realized to be towed, and manual carrying is not needed, effectively reducing the labor intensity.

[0045] Furthermore, the chute 141 is adapted to the fork 53. When feeding is required, the round straw bale is fed into the feed pipe 14 by the two forks 53. During the feeding process, the two forks 53 extend into their respective chute 141. At the same time, the round straw bale enters the feed pipe 14. Then, as the third drive 54 drives the two forks 53 to move in opposite directions, the round straw bale is lifted into the feed pipe 14 and supported by the feed pipe 14. The two forks 53 continue to move in opposite directions until they are disengaged from the chute 141.

[0046] In one embodiment, the forklift frame assembly 5 further includes a pair of limiting plates 55, which are fixedly connected to the connecting frame 51 at intervals, and a pair of forks 53 are slidably connected between the pair of limiting plates 55.

[0047] In this embodiment, the limiting plate 55 prevents the two forks 53 from rotating with the rotation of the round rod 52, so that the two forks 53 can move in opposite directions or towards each other under the rotation of the round rod 52.

[0048] To better understand this invention, the following is combined with... Figures 1 to 5 The technical solution of the present invention will be described in detail below: The livestock farm stores a large number of round straw bales. When feeding is needed, firstly, the fork 53 picks up a round straw bale and feeds it to the feed pipe 14. Simultaneously, the fork 53 inserts into the chute 141. At this time, the second drive 32 drives the ratchet wheel 31 to rotate. When the ratchet wheel 31 hooks the round straw bale, the second drive 32 stops, and the third drive 54 is activated, driving the two forks 53 to move in opposite directions, releasing the support of the forks 53 on the round straw bale and disengaging it from the chute 141. Then, the forks 53 insert into the forklift slot 13 to lift the entire device, which is then moved to the livestock farm by forklift. Then, the first drive unit 22 and the second drive unit 32 are activated. The cutter head 21 rotates, and the ratchet wheel 31 rotates. Driven by the ratchet wheel 31, the round straw bales move toward the cutter head 21, which crushes the straw bales. The crushed straw is discharged from the discharge port 12 to the livestock farm. The forklift moves along the length of the livestock farm while discharging the crushed straw. When one round straw bale is crushed, the workers use another forklift to deliver it to another round straw bale in the same way as before. This process of crushing and feeding is carried out simultaneously, saving time and effort.

[0049] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
