Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf curing, in particular to a simple ridge-type tobacco leaf drying and curing shed. Background Art

[0002] Tobacco curing, also known as "drying," involves processing fresh tobacco leaves harvested at the mature stage of the process into dry tobacco leaves that meet industrial raw material requirements through temperature and humidity adjustments, followed by a series of physical, physiological, and biochemical changes. Curing is generally categorized into two main methods: baking and sun-drying. Curing modifies the physical properties and chemical composition of tobacco leaves, resulting in dried leaves with varying quality characteristics (color, elasticity, oil content, aroma, and flavor). This facilitates storage and transportation, while also accommodating the production of different types and grades of tobacco products by tobacco companies using specific raw material ratios. Curing is currently performed in curing sheds, which are capable of meeting the drying requirements of tobacco leaves.

[0003] Patent No. CN216438535U discloses a sun-cured tobacco curing device, wherein the curing shed includes a support bracket and a shed body, the support bracket is used to support the shed body, and the shed body is provided with top and bottom vents; the top adjustment mechanism includes a top adjustment shed and a top adjustment unit, the top adjustment shed is rotatably connected to the support bracket, and the top adjustment unit is used to drive the top adjustment shed to rotate to close or open the top vent; the bottom adjustment mechanism includes a bottom adjustment member and a bottom adjustment unit, the bottom adjustment member is rotatably connected to the support bracket, and the bottom adjustment unit is used to drive the bottom adjustment member to rotate to close or open the bottom vent.

[0004] The above-mentioned curing equipment can dry a large number of tobacco leaves in multiple layers and can adjust the ventilation and air permeability to achieve the purpose of efficient and labor-saving tobacco curing; however, after the tobacco leaves are cured, the curing equipment cannot be disassembled and stored. The curing equipment will occupy space when idle, affecting the utilization of space. Utility Model Content

[0005] The utility model provides a simple ridge-type tobacco leaf drying and curing shed, which solves the problem in the prior art that the curing shed cannot be stored during idle time and occupies space.

[0006] The technical solution of the present utility model is achieved as follows:

[0007] A simple ridge - type tobacco leaf curing shed, comprising a support frame and a top covering. The support frame includes a rectangular - shaped folding frame. A foldable overlapping member is provided in the middle of the rectangular - shaped folding frame, and foldable support rods are provided at the bottom of the rectangular - shaped folding frame. The top covering overlaps on the top of the rectangular - shaped folding frame and the overlapping member. When curing tobacco leaves, the support frame is unfolded, and the top covering is set on the support frame. The top covering provides shelter to prevent rainwater from entering. The support frame adopts a foldable structure. After the tobacco leaves are dried, the support frame is stored by folding, avoiding the situation that the tobacco leaf curing shed occupies space and improving the space utilization rate.

[0008] The rectangular - shaped folding frame includes a bottom cross - bar, a middle cross - bar, and a top cross - bar arranged in sequence from bottom to top. Both ends of the bottom cross - bar are connected to the middle cross - bar through lower connecting rods; both ends of the top cross - bar are connected to the middle cross - bar through upper connecting rods. The top cross - bar provides support for the top covering, the middle cross - bar cooperates with the overlapping member to provide support for the tobacco leaves, and the bottom cross - bar and the support rods cooperate to provide support for the rectangular - shaped folding frame, making the rectangular - shaped folding frame in a vertical state.

[0009] The lower end of the lower connecting rod is hinged to the end of the bottom cross - bar, and the upper end of the lower connecting rod is slidably connected to the middle cross - bar. A first lower positioning tube is provided at the lower part of the lower connecting rod, and a second lower positioning tube is provided on the bottom cross - bar. When the lower connecting rod is perpendicular to the bottom cross - bar, the positions of the first lower positioning tube and the second lower positioning tube correspond, and a lower positioning rod is inserted into the first lower positioning tube and the second lower positioning tube. Through the cooperation of the lower positioning rod with the first lower positioning tube and the second lower positioning tube, the limit of the lower connecting rod and the bottom cross - bar is realized, so that the lower connecting rod and the bottom cross - bar always remain perpendicular when the curing shed is in use; after the lower positioning rod is taken out, the lower connecting rod rotates and folds relative to the bottom cross - bar to realize the storage of the lower connecting rod.

[0010] The upper end of the upper connecting rod is hinged to the end of the top cross - bar, and the lower end of the upper connecting rod is slidably connected to the middle cross - bar. A first upper positioning tube is provided at the upper part of the upper connecting rod, and a second upper positioning tube is provided on the top cross - bar. When the upper connecting rod is perpendicular to the top cross - bar, the positions of the first upper positioning tube and the second upper positioning tube correspond, and an upper positioning rod is inserted into the first upper positioning tube and the second upper positioning tube. Through the cooperation of the upper positioning rod with the first upper positioning tube and the second upper positioning tube, the limit of the upper connecting rod and the top cross - bar is realized, ensuring that the upper connecting rod and the top cross - bar remain perpendicular during use; after the upper positioning rod is taken out, the upper connecting rod rotates and folds relative to the top cross - bar to realize the storage of the upper connecting rod.

[0011] An upper positioning plate is provided at the lower end of the upper connecting rod, and a lower positioning plate is provided at the upper end of the lower connecting rod. Both the upper and lower positioning plates are provided with insertion holes. When the lower and upper connecting rods are perpendicular to the middle crossbar, positioning rods are inserted into the insertion holes. When the positioning rods are inserted into the insertion holes, the positioning rods limit the upper and lower positioning plates, thereby keeping the upper and lower connecting rods in a vertical position.

[0012] Guide rails are provided on both the upper and lower sides of the central crossbar. Sliders are rotatably connected to the upper and lower ends of the lower connecting rods, and the slides slide in engagement with the guide rails. Baffles are provided at the ends of the central crossbar. During folding or unfolding of the support frame, the slides slide on the guide rails, changing the angle of the upper or lower connecting rods relative to the central crossbar, thereby achieving folding of the support frame. The baffles also limit the sliding range of the slides, preventing them from disengaging from the guide rails.

[0013] The connecting member includes a first connecting rod and a second connecting rod. One end of the first connecting rod is hinged to the middle crossbar, and the other end of the first connecting rod is detachably connected to the second connecting rod. The second connecting rod is parallel to the middle crossbar. The second connecting rod and the middle crossbar provide support for the airing rod. After the tobacco leaves are connected to the airing rod, the airing rod is placed on the second connecting rod and the middle crossbar.

[0014] The left and right sides of the middle crossbar are provided with ear seats, and one end of the first connecting rod is provided with a hinge plate. The ear seats are arranged horizontally and cooperate with the hinge plate. The first connecting rod can be folded by hinged connection so that the first connecting rod fits with the left and right sides of the middle crossbar to realize the folding of the support frame.

[0015] The hinge plate is provided with a positioning hole, through which the positioning rod passes. The positioning rod cooperates with the positioning hole to limit the first lap joint rod, making it convenient to install the second lap joint rod.

[0016] At least two support rods are hinged on the left and right sides of the bottom cross bar. After the support rods are unfolded relative to the bottom cross bar, the support rods cooperate to keep the bottom cross bar stable, thereby ensuring the stability of the support frame.

[0017] The beneficial effects of this utility model are as follows: the support frame adopts a folding structure. When preparing tobacco leaves, the support frame is unfolded and the top cover is overlapped on the support frame. The tobacco leaves are then placed on the central crossbar and the overlapped piece to prepare the tobacco leaves. After the tobacco leaves are prepared, the support frame is folded and stored, eliminating the need for the tobacco leaf preparation shed to occupy space and improving space utilization. It can be quickly assembled and disassembled without taking up additional space, providing convenience and flexibility. It can be used during the tobacco leaf drying season and can be disassembled during the off-season without affecting other uses of the eaves drying dam.

[0018] Both ends of the bottom cross bar, the middle cross bar and the top cross bar are provided with positioning structures. After the support frame is unfolded, the positioning structure is used to limit the position to ensure that the unfolded state of the support frame is stable and that the support frame has good structural stability.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example 1, as Figure 1 、 Figure 2As shown in the figure, a simple gable - type tobacco - drying and modulating shed includes a support frame and a top covering. The support frame includes a rectangular - shaped folding frame. In the middle of the rectangular - shaped folding frame, there is a foldable overlapping part. At the bottom of the rectangular - shaped folding frame, there are foldable support rods 2. The top covering is overlapped on the top of the rectangular - shaped folding frame and the overlapping part. Specifically, at least two support rods 2 are respectively arranged on the left and right sides at the bottom of the rectangular - shaped folding frame. When the included angle between the support rod 2 and the rectangular - shaped folding frame is greater than 0 degrees, the support rod 2 provides support for the rectangular - shaped folding frame, making the rectangular - shaped folding frame in a vertical state, enabling the rectangular - shaped folding frame to support the tobacco leaves, facilitating the modulation of tobacco leaves. After the tobacco leaves are modulated, the support frame is stored by folding, avoiding the situation that the tobacco - drying and modulating shed occupies space and improving the space utilization rate.

[0028] In addition, the top covering is a transparent plastic film or a polyethylene net, which can prevent rainwater and dust from entering while ensuring light transmittance.

[0029] Furthermore, the rectangular - shaped folding frame includes a bottom cross - bar 1, a middle cross - bar 5, and a top cross - bar 7 arranged in sequence from bottom to top. The two ends of the bottom cross - bar 1 are connected to the middle cross - bar 5 through lower connecting rods 3; the two ends of the top cross - bar 7 are connected to the middle cross - bar 5 through upper connecting rods 8. The top cross - bar 7 and the overlapping part jointly provide support for the top covering, forming a gable - type structure to ensure air circulation in the shed; ropes can be set on the middle cross - bar 5 and the overlapping part, and the tobacco leaves can be hung on the ropes, facilitating the drying of tobacco leaves.

[0030] Furthermore, the lower end of the lower connecting rod 3 is hinged to the end of the bottom cross - bar 1, and the upper end of the lower connecting rod 3 is slidably connected to the middle cross - bar 5; a first lower positioning tube is provided at the lower part of the lower connecting rod 3, and a second lower positioning tube is provided on the bottom cross - bar 1. When the lower connecting rod 3 is perpendicular to the bottom cross - bar 1, the positions of the first lower positioning tube and the second lower positioning tube correspond to each other, and a lower positioning rod is inserted into the first lower positioning tube and the second lower positioning tube. Through the cooperation of the lower positioning rod with the first lower positioning tube and the second lower positioning tube, the limit of the lower connecting rod 3 and the bottom cross - bar 1 is realized, so that the lower connecting rod 3 and the bottom cross - bar 1 always maintain a vertical state when the modulating shed is in use; after the lower positioning rod is taken out, the lower connecting rod 3 rotates and folds relative to the bottom cross - bar 1, realizing the storage of the lower connecting rod 3.

[0031] Furthermore, the upper end of the upper connecting rod 8 is hinged to the end of the top cross bar 7, and the lower end of the upper connecting rod 8 is slidably connected to the middle cross bar 5; a first upper positioning tube is provided on the upper portion of the upper connecting rod 8, and a second upper positioning tube is provided on the top cross bar 7. When the upper connecting rod 8 is perpendicular to the top cross bar 7, the first upper positioning tube and the second upper positioning tube are positioned correspondingly, and an upper positioning rod is inserted into the first upper positioning tube and the second upper positioning tube. The upper positioning rod cooperates with the first upper positioning tube and the second upper positioning tube to limit the position of the upper connecting rod 8 and the top cross bar 7, ensuring that the upper connecting rod 8 and the top cross bar 7 remain in a vertical state when in use; after the upper positioning rod is removed, the upper connecting rod 8 is rotated and folded relative to the top cross bar 7 to achieve storage of the upper connecting rod 7.

[0032] Example 2, based on Example 1, a simple ridge-type sun-drying tobacco leaf curing shed, such as Figure 3 、 Figure 4 As shown, the lower end of the upper connecting rod 8 is provided with an upper positioning plate, and the upper end of the lower connecting rod 3 is provided with a lower positioning plate 31. Both the upper positioning plate and the lower positioning plate 31 are provided with a socket. When the lower connecting rod 3 and the upper connecting rod 8 are perpendicular to the middle crossbar 5, a positioning rod 9 is inserted into the socket. After the positioning rod 9 is inserted into the socket, the positioning rod 9 limits the upper positioning plate 81 and the lower positioning plate 31, thereby placing the upper connecting rod 8 and the lower connecting rod 3 in a vertical state, and the relative positions of the upper connecting rod 8, the middle crossbar 5, and the lower connecting rod 3 are fixed. When the support frame is folded, the positioning rod 9 is pulled out, and the upper connecting rod 8 and the lower connecting rod 3 are unlocked. At this time, the lower end of the upper connecting rod 8 and the upper end of the lower connecting rod 3 can slide relative to the middle crossbar 5.

[0033] Furthermore, guide rails 51 are provided on both the upper and lower sides of the central crossbar 5. Sliders 10 are rotatably connected to the upper end of the lower connecting rod 3 and the lower end of the upper connecting rod 8, and the sliders 10 slide in synergistic relationship with the guide rails 51. During the folding or unfolding of the support frame, the slides 10 slide on the guide rails 51, changing the angle of the upper connecting rod 8 or the lower connecting rod 3 relative to the central crossbar 5, thereby achieving folding of the support frame. Baffles 52 are provided at the ends of the central crossbar 5. Baffles 52 limit the sliding range of the slides 10, preventing them from dislodging from the guide rails.

[0034] Furthermore, the connecting member includes a first connecting rod 4 and a second connecting rod 6. One end of the first connecting rod 4 is hinged to the central crossbar 5, and the other end of the first connecting rod 4 is detachably connected to the second connecting rod 6. The second connecting rod 6 is parallel to the central crossbar 5. A slot is provided at the end of the first connecting rod 4, and a socket is provided at the end of the second connecting rod 6. The slot and the socket cooperate to achieve a detachable connection between the first connecting rod 4 and the second connecting rod 6. Hanging ropes or drying rods can be provided on the second connecting rod 6 and the central crossbar 5. Tobacco leaves can be hung on the hanging ropes or drying rods to dry and season the tobacco leaves.

[0035] In addition, the length of the first connecting rod 4 is smaller than that of the supporting rod 2, so that the sun-drying tobacco curing shed is pyramid-shaped when unfolded, which provides structural stability of the supporting frame to a certain extent.

[0036] Furthermore, ear seats 53 are provided on both the left and right sides of the middle crossbar 5. Figure 5 As shown, a hinged plate 41 is provided at one end of the first bridge rod 4, and a horizontally arranged ear seat 53 engages with the hinged plate 41. The first bridge rod 4 can be folded by hinged connection, so that the first bridge rod 4 is aligned with the left and right sides of the central crossbar 5, achieving foldable support frame. The hinged plate 41 is provided with a positioning hole 43, through which a positioning rod 9 passes. The positioning rod 9 cooperates with the positioning hole 43 to limit the position of the first bridge rod 4, ensuring stable deployment of the first bridge rod 4 and facilitating the installation of the second bridge rod 6.

[0037] The process of unfolding the tobacco leaf drying and curing shed is as follows: place the support frame on the open ground, rotate the support rod 2 to a certain angle so that the angle between the support rod 2 and the bottom cross bar 1 is greater than zero, thereby ensuring the stability of the bottom cross bar 1; lift the top cross bar 7 upwards, and in the process of lifting the top cross bar 7, the upper connecting rod 8 changes from a horizontal state to a vertical state, at this time, insert the upper positioning rod into the second upper positioning tube on the top cross bar 7 and the first upper positioning tube on the upper connecting rod 8 to fix the relative position of the top cross bar 7 and the upper connecting rod 8; lift the middle cross bar 5 upwards, and in the process of lifting the middle cross bar 5, the lower connecting rod 3 changes from a horizontal state to a vertical state, at this time Insert the lower positioning rod into the first lower positioning tube on the lower connecting rod 3 and the second lower positioning tube on the bottom cross bar 1 to fix the relative position of the lower connecting rod 3 and the bottom cross bar 1; rotate the first overlapping rod 4 so that the first overlapping rod 4 is perpendicular to the middle cross bar 5. At this time, install the positioning rod 9 to connect the positioning rod 9 to the upper connecting rod 8, the first overlapping rod 4 and the lower connecting rod 3. The positioning rod 9 limits the first overlapping rod 4 to ensure that the first overlapping rod 4 is stable; connect the second overlapping rod 6 to the end of the first overlapping rod 4; finally, place the top cover on the top cross bar 7 and the second overlapping rod 6 to form a ridge structure, and the tobacco drying and curing shed is completed.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
