Description

Technical Field

[0001] This utility model relates to the field of cigar planting and harvesting technology, and in particular to a cigar frame. Background Technology

[0002] Cigars are hand-rolled whole-leaf products, and their quality heavily depends on the quality of the tobacco leaves. A cigar consists of the wrapper, binder, and filler, with the wrapper being the outermost layer. Its appearance and integrity are paramount. However, improper storage during transport to drying rooms after harvesting causes mechanical damage to the tobacco leaves due to compression, leading to a decline in appearance quality and reduced wrapper yield. In the tobacco harvesting stage, the standardization of the packing process and the appropriateness of the transport tools directly affect the quality of the tobacco leaves and the efficiency of subsequent processing. Currently, the industry commonly uses a four-corner packing method, where tobacco leaves are manually placed into a transport frame in a four-corner shape, with 15-25 leaves per bundle, the leaf base close to the corner of the frame. This aims to improve packing uniformity and reduce mechanical damage through a "concave corners, convex center" filling pattern. However, this method has significant drawbacks in practice: the packing process is highly dependent on operator skill. Due to the large fluctuation in the number of tobacco leaves per bundle (15-25 leaves), it is difficult to ensure a consistent density of tobacco leaves in the four corner areas during manual placement. This easily leads to deviations in the amount of tobacco loaded in a single frame (some frames only weigh 260kg±50kg, far below the standard of 450kg±10kg). Furthermore, the uneven stress on the tobacco leaves in the raised center and concave corners makes the leaves in the raised areas prone to compression and damage during transportation and subsequent processing, contradicting the design intention of "reducing mechanical damage." Balancing loading efficiency with standardization is difficult. The four-corner positioning method requires precise manual alignment of the frame corners, a cumbersome process that is time-consuming for inexperienced personnel, resulting in overall low efficiency in the harvesting process. Simultaneously, the difference in the shape of the tobacco leaves within the frame ("raised center, concave corners") leads to inconsistent ventilation and temperature / humidity environments, potentially affecting the quality stability of the tobacco leaves in the subsequent drying process.

[0003] In terms of the use of transfer frames, if only one layer of tobacco leaves is placed on the vehicle without stacking during transportation to reduce mechanical damage, it will reduce harvesting efficiency and cause economic losses to tobacco farmers. The shortcomings of existing equipment further exacerbate the above problems. When loading tobacco, the leaves easily overflow the frame, failing to reach the intended loading weight and increasing losses. The existing transfer frames lack sufficient cushioning and protection; both manual collisions during loading and bumps and compressions during transportation can cause mechanical damage to the tobacco leaves, further reducing their grade. Therefore, addressing the operational pain points of the four-corner loading method and the structural defects of the transfer frame, there is an urgent need to design an improved tobacco loading and transfer frame that balances ease of operation, standardized loading, transportation stability, and economical maintenance to solve the aforementioned problems in the existing technology. Utility Model Content

[0004] In view of the shortcomings in the above-mentioned background technology, this utility model proposes a tobacco frame for harvesting eggplant wrappers, which solves the problems of low tobacco loading efficiency, uneven density, and easy damage to tobacco leaves in the prior art.

[0005] The technical solution of this utility model is as follows: a tobacco frame for harvesting eggplant wrappers includes a frame body, with limiting components at the four corners of the frame body for limiting the base of the tobacco leaves, and a buffer dividing component for balancing the density of the tobacco in the frame body. The upper part of the frame body is provided with at least two supporting rods to prevent the tobacco leaves from being squeezed when the frames are stacked.

[0006] More preferably, the bottom of the frame is provided with a base corresponding to the limiting component.

[0007] More preferably, the limiting component includes a column, and the middle part of the column is provided with an arc-shaped groove that mates with the blade base.

[0008] Further preferably, the column is provided with a scale bar.

[0009] More preferably, the buffer partition assembly includes at least one buffer partition plate arranged parallel to the bottom of the frame, and the buffer partition plate is provided with at least two legs.

[0010] More preferably, the support leg includes an upper support leg and a lower support leg, and the upper support leg and the lower support leg are provided with a plurality of corresponding adjustment holes, which are fixed by positioning pins.

[0011] More preferably, the lower part of the lower support leg is provided with a support plate to increase stability.

[0012] More preferably, the supporting rod is a U-shaped rod, with both sides of the U-shaped rod rotatably connected to the frame.

[0013] In a further preferred embodiment, both sides of the symmetrically arranged U-shaped rod include a sleeve, a connecting rod is slidably provided inside the sleeve, and a rotating shaft is provided on the sleeve, with the sleeve rotatably connected to the frame through the rotating shaft.

[0014] More preferably, the connecting rod is provided with a slider that slides along the inner wall of the sleeve, and the slider is restricted inside the sleeve by a baffle on the sleeve.

[0015] The beneficial effects of this utility model are as follows: This utility model has a simple structure. Limiting components are set at the four corners of the frame to limit the leaf base, which makes it convenient for tobacco farmers to place tobacco leaves, ensures that the tobacco leaves are stacked flat, is easy to use, and optimizes the stacking effect of tobacco leaves. The buffer dividing component can support the tobacco leaves in the frame to prevent them from being stacked too high, and also prevent the tobacco leaves in the frame from being too high in the middle and too low on both sides. The supporting rod reduces the mechanical damage caused by compression during the transportation of cigar tobacco leaves, improves the integrity of cigar tobacco leaves, and thus improves the yield of wrapper tobacco leaves. It can reduce the compression of tobacco leaves by the frame during transportation, prevent damage to the integrity of tobacco leaves due to frame compression, and improve transportation efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1As shown in Embodiment 1, a tobacco frame for harvesting cigar wrappers includes a frame body 1. Each of the four corners of the frame body 1 has a limiting component to restrict the tobacco leaf base. The frame body 1 also has a buffer dividing component to balance the density of the tobacco leaves. At least two support rods 2 are provided on the upper part of the frame body 1 to prevent the tobacco leaves from being crushed during stacking. The support rods 2 on the upper part of the frame body reduce mechanical damage caused by compression during cigar tobacco leaf transportation, improve the integrity of the cigar tobacco leaves, and thus increase the yield of cigar wrapper tobacco leaves. The structure is simple. The limiting components at the four corners of the frame body 1 facilitate the placement of tobacco leaves by tobacco farmers, ensuring a flat stack of tobacco leaves. It is easy to use and optimizes the stacking effect of tobacco leaves. The buffer dividing components support the tobacco leaves within the frame body 1, preventing excessive stacking and also preventing the middle of the tobacco leaves from being too high and the sides too low. The bottom of the frame body 1 has a base 5 corresponding to the limiting components. The base 5 facilitates bottom ventilation when the tobacco leaves are placed. The base 5 is preferably a triangular base 5. When the cigarette frames are stacked, the base 5 is placed on the limiting component, which can provide good support for the frame 1.

[0024] like Figure 2 and 3 As shown in Embodiment 2, a tobacco frame for harvesting tobacco leaves includes a limiting component comprising a column 3 with an arc-shaped groove 3-1 in the middle that mates with the leaf base. The column has a graduated strip 3-2. The outer wall of the column 3 engages with the inner corner of the frame 1. The arc-shaped groove 3-1 on the inner wall of the column 3 limits the position of the tobacco leaf bases stacked at the four corners. The column 3 is higher than the frame 1, facilitating the stacking of the frame 1 containing tobacco leaves. The graduated strip 3-2 allows the operator to clearly see any deviations in the stacking at the four corners, improving the stacking effect. The column 3 and frame 1 are detachably connected, allowing for two loading methods: the first is to place the column 3 inside the frame 1, and after loading, remove the column 3 and place it in the next loading frame for reuse; in this case, the column 3 provides no support. The second method involves keeping the column 3 always engaged with the frame 1, providing support when the frame 1 containing tobacco leaves is stacked; this method is more costly.

[0025] All other structures are the same as in Example 1.

[0026] like Figure 3 As shown in Embodiment 3, a tobacco frame for harvesting tobacco leaves includes a buffer dividing assembly comprising at least one buffer dividing mesh plate 4 arranged parallel to the bottom of the frame 1, with at least two support legs on the buffer dividing mesh plate 4. The buffer dividing mesh plate 4 is used for layering the tobacco leaves within the frame 1. The support legs are used to support the buffer dividing mesh plate 4, preventing the buffer dividing mesh plate 4 from compressing the tobacco leaves.

[0027] In this embodiment, the support legs include an upper support leg 4-1 and a lower support leg 4-2. The upper support leg 4-1 and the lower support leg 4-2 are provided with several corresponding adjustment holes 4-3, which are fixed together by positioning pins. The lower support leg 4-2 has a support plate 4-5 at its lower part to increase stability. The upper support leg 4-1 and the lower support leg 4-2 work together to adjust the height according to the frame 1. This design has a wide range of applications. When two buffer partition plates 4 are stacked on the upper plane of the frame 1, the two buffer partition plates 4 can support the stacking of two adjacent frames 1, making it suitable for small-scale transportation.

[0028] All other structures are the same as in Example 2.

[0029] like Figure 2 and 4 As shown in Embodiment 4, a tobacco frame for harvesting eggplant wrappers is provided. The supporting rod 2 is a U-shaped rod, with both sides of the U-shaped rod rotatably connected to the frame 1. The length of the crossbar of the U-shaped rod is greater than the width of the frame 1. When a column 3 is provided inside the frame 1, the height of the crossbar on the frame 1 is equal to the height of the column 3 above the frame 1. When there is no column 3 inside the frame 1, a groove is provided at the top of the frame 1, and the crossbar is placed in the groove without exceeding the upper surface of the frame 1. The two symmetrically arranged rods on both sides of the U-shaped rod each include a sleeve 2-2 and a connecting rod 2-1 slidably disposed within the sleeve 2-2. One end of the sleeve 2-2 is provided with a pivot 2-5, and the sleeve 2-2 is rotatably connected to the frame 1 through the pivot 2-5. The other end of the sleeve 2-2 is provided with a baffle 2-4 for limiting the slider 2-3 of the connecting rod 2-1. The connecting rod 2-1 slides along the sleeve 2-2, facilitating the adjustment of the position of the supporting rod 2 on the frame 1.

[0030] All other structures are the same as in Example 3.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
