[0031] At the same time, the straw forming assembly 3 of the present invention includes a movable pressing plate 31, a fixed pressing plate 32 and a bundling cover plate 33. Among them, the movable pressing plate 31 is arranged at the driving end of the bidirectional stamping assembly 2, and the movable pressing plate 31 moves with the bidirectional stamping assembly 2 when the straw is pressed and baled; the fixed pressing plate 32 is fixedly arranged on the working platform 1, and the fixed pressing plate 32 and the movable pressing plate 31 are arranged oppositely; the bundling cover plate 33 is hinged on the working platform 1. When the movable pressing plate 31 moves to a preset position, the movable pressing plate 31, the fixed pressing plate 32, the bundling cover plate 33 and the working platform 1 enclose a straw forming cavity 4; the circumferential bottom end and both side ends of the straw forming cavity 4 are provided with bundling grooves 5 for the bundling wire to pass through for bundling of the straw. Its straw forming structure is simple, and it is convenient to quickly and effectively bundle the formed straw.

[0032] Further, Figure 4 and Figure 5 As shown, the straw baling machine also includes a wire bending assembly 6, which includes a swinging crossbar 61 and two driving rods 62. Among them, the swinging crossbar 61 is arranged along the length direction of the straw forming cavity 4, and the swinging crossbar 61 is located below the working platform 1; along the swinging direction of the swinging crossbar 61, the swinging crossbar 61 is located upstream of the wire inserted into the bundling groove 5, so that the swinging crossbar 61 can effectively bend the wire vertically placed in the bundling groove 5 to achieve effective straw bundling. The two driving rods 62 are connected to the two ends of the swinging crossbar 61, and the two driving rods 62 are respectively hinged on the two side walls of the working platform 1. By operating the driving rod 62, the swinging crossbar 61 can be driven to move, so that the wire is bent and convenient bundling. The wire bending assembly 6 of the present invention has a simple structure and is easy to operate, and can achieve fast and effective straw bundling.

[0033] Furthermore, the wire-bending assembly 6 further includes two limit springs 63. The two limit springs 63 are respectively connected to the driving rod 62 and the working platform 1 on the corresponding side, and the connection point between the limit spring 63 and the working platform 1 is located above the connection point between the driving rod 62 and the working platform 1. The limit spring 63 is in a stretched state in the initial state and the wire-bending state, so that the driving rod 62 is stably limited, ensuring the smooth and reliable bundling operation.

[0034] like Figure 3 and Figure 7 As shown, in this embodiment, the bundling groove 5 includes a first vertical section 51 provided on the movable pressing plate 31, a second vertical section 52 provided on the fixed pressing plate 32, and a horizontal section 53 provided on the working platform 1, and the first vertical section 51, the horizontal section 53 and the second vertical section 52 are connected in sequence to facilitate the bundling of the wires. At the same time, a wire-binding limiter 7 is provided directly below the first vertical section 51, and the wires are passed through the first vertical section 51 and are vertically limited by the wire-binding limiter 7. In other embodiments, a wire-binding limiter 7 may also be provided directly below the second vertical section 52, and the wires are first passed through the second vertical section 52, and then passed through the horizontal section 53 and the first vertical section 51 in sequence for bundling. In this embodiment, the wire-binding limiter 7 is a limiter plate, which is arranged along the arrangement direction of the bundling groove 5, and the limiter plate is installed on the supporting foot of the working platform 1.

[0035] When the swing cross bar 61 is driven by the driving rod 62 to bend the binding wire, the binding wire is bent into the horizontal section 53 and is located below the second vertical section 52. Afterwards, the binding wire passes through the second vertical section 52 for bundling, which is convenient and efficient.

[0036] Furthermore, a through operation area 8 is provided at one end of the fixed pressing plate 32 away from the movable pressing plate 31, so as to facilitate manual or equipment lifting of the bundled wires under the working platform 1 for subsequent wire tying operations. At the same time, a plurality of partition plates 81 are provided along the arrangement direction of the bundling grooves 5, and each partition plate 81 is located between adjacent bundling grooves 5 to prevent adjacent bundled wires from interfering with each other.

[0037] Furthermore, the bundling grooves 5 are arranged at equal intervals along the length direction of the straw forming cavity 4, so that the formed straw can be bundled neatly, evenly, firmly and durable.

[0038] like Figure 2 As shown, in this embodiment, the straw baling machine further includes a push-out assembly 9.
