Figure 10 (As shown).

[0042] The weighing tobacco cart with a single sensor in this embodiment is used in conjunction with extrusion compression, packaging and discharging equipment.

[0043] In use, the tobacco leaves to be packaged (or other leafy agricultural products, such as kelp) are first filled into the cavity from the top. After weighing (the weight value sensed by the weighing sensor 19 will be displayed on the display screen 8 via a signal line), the weighing and packing cart with a single sensor in this embodiment is then sent to the matching compression, packing, and unloading equipment. During the entry process, the positioning guide component will accurately guide it to move to the compression and packing platform. At this time, the four casters of its moving component will accurately press on the settling part of the compression and packing platform. Moreover, the pair of load-bearing pressure relief beams 3 under the chassis frame 13 are positioned above the two load-bearing beams on the compression and packing platform after being exposed below the base frame 14.

[0044] Subsequently, the compression mechanism of the supporting equipment presses downward into the cavity to compress the tobacco leaves inside. When the tobacco leaves in the cavity are compressed to a certain extent (i.e., before damaging the casters), the four casters will compress the sinking part of the compression packing platform (see Chinese Patent CN201921614534.8), causing the four casters to sink and allowing a pair of load-bearing pressure relief beams 3 to rest on the two load-bearing beams on the compression packing platform. At this time, on the one hand, the four casters no longer bear pressure, and on the other hand, the pressure continues to compress the tobacco leaves in the cavity. (During this process, the pressure transmitted to the vehicle body underframe 13 will be transmitted to the two load-bearing beams on the compression packing platform through the pair of load-bearing pressure relief beams 3, thereby preventing it from being transmitted to the base through the weighing sensor 19.) (Frame 14, which in turn causes damage to the weighing sensor 19). When the pressure on the tobacco leaves in the cavity reaches the set value, the downward pressure stops. Then, the lifting component in the supporting equipment descends and hooks onto the lifting plate 11 on the front and rear lifting door frames 10. Then, it lifts the front and rear lifting door frames 10 upwards. When it reaches the set height, it stops rising. At this time, since the front and rear lifting door frames 10 of the weighing tobacco cart with a single sensor in this embodiment are lifted, the front and rear sides of the compressed tobacco leaves at the bottom are exposed. Then, the discharge component in the supporting equipment pushes the compressed tobacco leaves in the cavity from front to back or from back to front out (i.e., squeezes them out) from the cavity of the weighing tobacco cart with a single sensor, thereby realizing the discharge of the compressed tobacco leaf bale. Afterwards, the compression mechanism of the supporting equipment retracts upwards. At the same time, the lifting component in the supporting equipment descends and releases the hooked lifting plate 11, and then retracts upwards. Thus, the weighing tobacco cart with a single sensor in this embodiment can be sent out of the supporting equipment, and the above actions are repeated.

[0045] This utility model relates to a weighing and packing cart with a single sensor, which is used in conjunction with an extrusion compression, packaging and discharging device. It can be used for compressing and bagging tobacco leaves, as well as leaf and stem agricultural products such as rice straw, wheat straw and kelp.
