The guide mechanism is composed of a guide rod 23, a guide sleeve 24 and a guide rod end plate 26. The guide sleeve 24 is arranged on the top frame 25, the guide rod 23 is sleeved in the guide sleeve 24, and the lower end of the guide rod 23 is connected to the guide rod end plate 26. The lower surface of the compression plate 20 and the guide rod end plate 26 is connected to the tobacco compression plate 19 (the lower surface of the tobacco compression plate 19 is as smooth as the inner surface of the inner plate 50 of the box body). The compression cylinder 22 is connected to the multi-way control valve 13 of the hydraulic assembly through an oil pipe.

[0044] The hydraulic assembly is arranged on the side top frame 43, which is composed of an oil tank 7, an oil pump 16 and a multi-way control valve 13, the pump body of the oil pump 16 is immersed in the oil tank 7, the motor of the oil pump 16 is exposed from the oil tank 7, the oil pump 16 is connected with the multi-way control valve 13 through an oil pipe, and the multi-way control valve 13 is connected with the compression cylinder 22 and the extrusion cylinder 6 through oil pipes respectively. A pressure gauge 12 is further arranged on the multi-way control valve 13 for monitoring the pressure of the oil circuit. The multi-way control valve 13 is further provided with a compression cylinder control lever 15 and an extrusion member control lever 14 and a pressure regulating valve 53 respectively for controlling the compression cylinder 22 and the extrusion cylinder 6.

[0045] The electric control assembly is arranged on the side top frame 43, which includes a start-stop switch 17 and an electric control box 8, and an emergency stop switch 10 and a power indicator 9 are further arranged on the electric control box 8, and the electric control box 8 is connected with the start-stop switch 17 and the motor of the oil pump 16 in sequence through control lines.

[0046] Before use, the mobile extrusion bale type tobacco leaf packing machine is moved to a slightly spacious site, the power is turned on, the weighing parameters are set on the weighing display screen 11, the upper limit value of the oil pressure is adjusted through the pressure regulating valve 53 (usually set as 10 MPa), and then the machine can be used.

[0047] In use, first open the front and rear loading door 28, and then arrange the tobacco leaves to be packed into the tobacco leaf compression cavity 29 in the left-right direction, one layer after another (i.e. if the left end of the lower layer is placed with the tobacco leaf stem, then the left end of the upper layer is placed with the tobacco leaf tip). When the tobacco leaves are filled to the upper end of the tobacco leaf compression cavity 29, then close the front and rear loading door 28 and continue to fill, until the tobacco leaves in the tobacco leaf compression cavity 29 reach the set weight value, at which time the weighing display screen 11 will emit an alarm sound. Next, press the start button on the start-stop switch 17 to start the oil pump 16. Next, place the open end of the packed tobacco bag into the left port of the bale-out member 32, and then place it into the bale-out member 32. Then, move the compression cylinder control lever 15, and the compression cylinder 22 starts to work. The compression cylinder shaft 21 of the compression cylinder 22 extends downward, and pushes the compression plate 20 and the tobacco compression plate 19 downward to compress the tobacco leaves in the tobacco leaf compression cavity 29. When the tobacco compression plate 19 cannot be further compressed in the tobacco leaf compression cavity 29, the pressure in the oil circuit will exceed the set value (i.e. more than 10 MPa). At this time, the pressure regulating valve 53 will automatically release the excess pressure and remain in the current position. At the same time, the position of the tobacco compression plate 19 is slightly lower than the inner surface of the upper wall of the inner cavity of the bale-out member 32, so that the extrusion plate 42, the extrusion liner 44 and the inner plate 50 of the box can enter the inner cavity of the bale-out member 32. Next, move the extrusion member control lever 14, and the extrusion cylinder 6 starts to work. The extrusion cylinder shaft 41 of the extrusion cylinder 6 moves the extrusion plate 42, the extrusion liner 44 and the inner plate 50 of the box to the left side of the tobacco leaf compression cavity 29, and pushes the compressed tobacco leaves in the tobacco leaf compression cavity 29 to the left side of the bale-out member 32, and then enters the packed tobacco bag, and with the continuous extrusion of the extrusion cylinder 6, the tobacco leaves in the packed tobacco bag will be stretched to the left. When the extrusion cylinder shaft 41 of the extrusion cylinder 6 moves to the left side of the tobacco leaf compression cavity 29, it will continue to move to the left and enter the inner cavity of the bale-out member 32, until the extrusion cylinder shaft 41 of the extrusion cylinder 6 extends to the limit position (at this time, the extrusion cylinder 6 will stop working and remain in the current state). At this time, the compressed tobacco leaves in the tobacco leaf compression cavity 29 are completely extruded into the packed tobacco bag, and the extrusion liner 44 and the inner plate 50 of the box are at the left port of the bale-out member 32. At this time, the packed tobacco bag can be pulled away and sewn at the right port. Thus, one weighing, compressing and bagging operation is completed. Then, move the extrusion member control lever 14 again, and the extrusion cylinder shaft 41 of the extrusion cylinder 6 moves the extrusion plate 42, the extrusion liner 44 and the inner plate 50 of the box to the right to reset. Then, move the compression cylinder control lever 15 again, and the compression cylinder shaft 21 of the compression cylinder 22 moves the compression plate 20 and the tobacco compression plate 19 upward to reset.

[0048] During the movement of the extrusion cylinder shaft 41 of the extrusion cylinder 6 to the left tobacco compression cavity 29 and into the inner cavity of the baling member 32 (including the reset return), the supporting wheel 47 arranged at the lower right side of the extrusion liner 44 rolls along the inner cavity bottom surface of the baling member 32 and the bottom surface of the box inner plate 50 of the tobacco compression cavity 29, so as to ensure that the axis of the extrusion cylinder shaft 41 is consistent with the inner hole axis of the extrusion cylinder 6, thus avoiding the deformation of the extrusion cylinder shaft 41 and reducing the wear of the bottom surface of the box inner plate 50 of the tobacco compression cavity 29 and the inner cavity bottom surface of the baling member 32, thereby prolonging the service life of the equipment.

[0049] When the compression cylinder 22 works, the pressure generated by the compression cylinder 22 acts inside the frame assembly, thus not affecting the weighing assembly arranged below the chassis 31 of the frame assembly (i.e. not damaging the directional end weighing sensor 33 and the universal end weighing sensor 2 due to excessive pressure), and not damaging the moving assembly arranged below the weighing assembly (i.e. not damaging the directional casters 36 and the universal casters 3).

[0050] Since the extrusion and pushing baling direction is the length direction of the tobacco, and the inner wall of the pushing channel is relatively smooth, the quality of the tobacco will not be damaged like the transverse pushing mode.

[0051] The moving and weighing extrusion baling type tobacco baling machine can be used for the weighing, compression and bagging of tobacco, and also can be used for the weighing, compression and bagging of leaf and stem agricultural products such as straw, wheat straw and kelp.
