Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically to a double-swing baffle type smoke-collecting mechanism. Background Technology

[0002] In the tobacco curing process, the tobacco-supporting mechanism is a key component of the tobacco loading machine. Its core function is to support and secure the tobacco clips, ensuring they are correctly placed on the curing racks in the curing barn. Traditional tobacco loading machines mostly employ a fixed structure, where two tobacco-supporting plates are rigidly connected to a support frame, forming a fixed horizontal distance. However, this structure has significant drawbacks in practical applications: due to the oblong-lanceolate leaf shape of tobacco leaves and the top-narrow, bottom-wide shape caused by the stacking of tobacco leaves in the clips, the tobacco leaves are easily subjected to rigid compression and scraping by the tobacco-supporting plates during the curing process, leading to leaf damage, vein breakage, and other problems. This, in turn, reduces the quality of the tobacco and directly impacts its economic benefits. Therefore, there is an urgent need for a tobacco-supporting mechanism that is simple in structure, self-adjustable, and can effectively reduce tobacco leaf damage to meet the demands for high-efficiency and high-quality tobacco production. Summary of the Invention

[0003] To achieve the above objectives, this utility model provides a double-swing baffle-type tobacco racking mechanism. This mechanism effectively alleviates mechanical compression damage caused by the stacking of tobacco leaves during flue-cured tobacco loading by adaptively adjusting the distance between the two racks. Furthermore, its structure is simple, reliable, and highly adaptable, significantly improving the efficiency of flue-cured tobacco loading and the quality of the finished tobacco product.

[0004] This utility model is achieved using the following technical solution:

[0005] A double-swing baffle-type tobacco racking mechanism includes support rods, tobacco racking plates, connecting rods, and a base plate. There are four support rods, each with a base having two through holes at its bottom and a longitudinal guide groove in the middle. The four support rods are symmetrically and vertically fixed to the left and right long sides of the base plate by screws, two rods on each side. There are two tobacco racking plates, with their long side edges hinged to the tops of the corresponding two support rods. There are four connecting rods, one end of which is hinged to the bottom plane of the tobacco racking plate, and the other end is embedded in the longitudinal guide groove. When the tobacco racking plate is subjected to an oblique thrust from stacked tobacco leaves, the connecting rods can be vertically displaced along the longitudinal guide groove, guiding the two tobacco racking plates to rotate synchronously in opposite directions, dynamically adjusting the horizontal distance.

[0006] Furthermore, the base is fixed to the base plate by screws, and the longitudinal guide groove is connected to the connecting rod by bolts through the hinge hole to form a vertical moving pair. The longitudinal guide groove is 65 mm long, and the top end of the longitudinal guide groove is 100 mm away from the top end of the support rod.

[0007] Furthermore, a baffle is provided on the upper surface of one side of the smoke rack, and a lower plate hinge support and an edge hinge support are symmetrically provided on the other side. The lower plate hinge support forms a rotating pair with the connecting rod, and the edge hinge support forms a rotating pair with the support rod, so that the smoke rack can reciprocate within the range of 0° to 85° and can be reset to a horizontal state under the action of gravity.

[0008] This utility model has the following beneficial effects:

[0009] (1) Through the linkage design of the support rod assembly, the tobacco rack assembly and the connecting rod assembly, the dynamic adaptive adjustment of the spacing of the tobacco rack plates is realized, which significantly reduces the mechanical compression damage rate when the tobacco leaves are stacked and loaded into the kiln.

[0010] (2) A symmetrical double swing baffle structure and guide groove limit constraint are adopted to ensure the stability of synchronous reverse rotation of the tobacco rack, adapt to different tobacco leaf thickness distribution requirements, and improve the adaptability of the mechanism in the tobacco production process;

[0011] (3) The overall structure is simple, no complex drive device is required, the manufacturing cost is low and the reliability is high. It can be applied to existing tobacco curing and loading machines to improve economic benefits. Attached Figure Description

[0018] like Figure 1As shown in the figure, this embodiment provides a double-swing baffle-type tobacco racking mechanism, including support rods 1, tobacco racking plates 2, connecting rods 3, and a base plate 4; characterized in that: there are four support rods 1, each with a base 11 having two through holes at the bottom and a longitudinal guide groove 12 in the middle, and the four support rods 1 are symmetrically and vertically fixed to the base plate 4 on the left and right long sides by screws, two on each side; there are two tobacco racking plates 2, with the long side edge of each tobacco racking plate 2 hinged to the top of the two support rods 1 on the corresponding side; there are four connecting rods 3, one end of each connecting rod 3 is hinged to the bottom plane of the tobacco racking plate 2, and the other end is embedded in the longitudinal guide groove 12; when the tobacco racking plate 2 is subjected to an oblique thrust of stacked tobacco leaves, the connecting rods 3 can generate vertical displacement along the longitudinal guide groove 12, guiding the two tobacco racking plates 2 to rotate synchronously in opposite directions, so as to dynamically adjust the horizontal distance between the two tobacco racking plates 2.

[0019] like Figure 2 As shown, there are four support rods 1 in total, and a rectangular base 11 with two through holes is welded to the bottom of each rod. The base 11 is fastened to the pre-set threaded hole of the base plate 4 by screws to ensure that the support rod 1 is vertically fixed on the base plate 4. A longitudinal guide groove 12 is milled in the middle of the support rod 1. The longitudinal guide groove 12 is connected to the connecting rod 3 by bolts through the reamed hole to form a vertical sliding pair. The longitudinal guide groove 12 is 65 mm long and the top of the longitudinal guide groove 12 is 100 mm away from the top of the support rod.

[0020] like Figure 3 As shown, there are two tobacco rack plates 2. A baffle 21 is vertically welded to the upper surface of one long side of the rack plate to limit the horizontal displacement of the tobacco clips during operation. A lower plate hinge support 22 and an edge hinge support 23 are symmetrically welded to the other side of the tobacco rack plate 2. The lower plate hinge support 22 is connected to the connecting rod 3 by bolts through the hinge hole to form a rotating pair. The edge hinge support 23 is connected to the support rod 1 by bolts through the hinge hole to form a rotating pair. This allows the tobacco rack plate 2 to reciprocate between 0° and 85° and can return to a horizontal state under the action of gravity to continue the next round of tobacco loading.

[0021] like Figure 4 As shown, there are four connecting rods 3 in total. One end of the connecting rod is connected to the lower plate surface hinge support 22 of the smoke rack 2 by bolts through the hinge hole, and the other end is connected to the longitudinal guide groove 12 by bolts through the hinge hole to form a vertical moving pair.
