The tobacco baler reduces the labor intensity of the balers and improves the baling efficiency. It is widely used in various tobacco leaf purchasing stations of Qianxinan Prefecture Tobacco Company in Guizhou Province.

[0003] Although the tobacco baler has greatly improved efficiency, there are still certain safety hazards in the entire baling process. Specifically, tobacco baling involves a discharge process, in which the tobacco baler is in a semi-open state and then baling is carried out. In the tobacco baling process, two or more people assist in the process, and if the degree of coordination is not enough, it is easy to cause safety accidents.

[0004] Based on this, a mobile tobacco baler with a safety protection mechanism is proposed. Utility Model Content

Figure 2 As shown, the top end of the protective plate 52 can move counterclockwise within a range of 90 degrees with the side end of the top support plate 51 as the axis, that is, when the top support plate 51 and the protective plate 52 are unfolded, the closing operation of the side semi-open silo of the baling machine body 1 can be completed.

[0026] The electromagnets 53 are provided in two groups, and each group of the electromagnets 53 is provided with two. The two electromagnets 53 in the same group are respectively installed at adjacent end corners of the top support plate 51 and the protective plate 52. After the top support plate 51 and the protective plate 52 are in the unfolded state, the magnetic force generated between the two electromagnets 53 in the same group is used to fix the relative state of the top support plate 51 and the protective plate 52, that is, the top support plate 51 and the protective plate 52 are in a 90-degree vertical installation state.

[0027] The bottom safety protection mechanism 6 includes a bottom movable plate 61, a bottom hinge 62, a pressure sensor 63 and an adjustment cylinder 64.

[0032] Then, the adjustment cylinder 64 is contracted to drive the bottom movable plate 61 to move upward, so that the pressure sensor 63 at the top of the bottom movable plate 61 is against the groove of the protective plate 52. When the pressure value of the pressure sensor 63 reaches the preset value, it can be determined that the packaging cavity 2 is completely closed, and the hydraulic cylinder 41 can be used to drive the packaging pressure plate 4 to press down, so that the packaging pressure plate 4 cooperates with the packaging support 3 to complete the packaging operation of the tobacco leaves.
