Description

Technical Field

[0001] This invention relates to the field of auxiliary devices for tobacco curing, and specifically to a drawer-pull type tobacco feeder device. Background Technology

[0002] Tobacco curing is crucial for producing high-quality tobacco leaves, and it is also the most labor-intensive, time-consuming, and technically demanding stage in the tobacco production process. Currently, although methods such as tobacco clamping and biomass new energy technologies are used in intensive curing barns, the supporting facilities for new and simplified equipment are inadequate, and the production methods are simple and extensive, failing to maximize the advantages of intensive curing barns in terms of simplified production.

[0003] The core process of the most widely used technology in small and medium-sized tobacco-growing areas is as follows: After harvesting fresh tobacco leaves, farmers first tie each leaf to a bamboo pole (or tobacco clip). Then, they manually lift the bamboo poles / tobacco clips to the multi-layered steel (or wooden) tobacco racks inside the curing barn. Finally, they manually place each bamboo pole / tobacco clip onto the crossbeams of the rack. Some simple curing barns don't even have fixed tobacco racks, requiring farmers to stand on ladders and lay the tobacco leaves directly on pre-installed wooden crossbeams inside the barn to complete the "loading" process. The advantage of this technology is that it requires no additional equipment investment, has a low operational threshold, and is suitable for small, scattered tobacco fields; however, it is essentially still "manual handling + manual placement," without any mechanized assistance. This method obviously suffers from low operational efficiency and high labor intensity. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a drawer-pull type smoke machine device to realize the batch and mechanized loading and unloading of smoke clamp units, and solve the problems of high labor intensity, low work efficiency and poor safety of manual loading in the prior art.

[0005] To address the above problems, the present invention provides the following technical solution:

[0007] The vertical guide rails are fixed inside the drying room; there are at least four vertical guide rails, and these vertical guide rails are arranged in pairs close to the left and right side walls of the drying room;

[0008] The electrically controlled lifting assembly includes a support platform and an electrically controlled drive unit; the left and right ends of the support platform are respectively installed in the vertical guide rails, and the support platform can move along the vertical guide rails under the drive of the electrically controlled drive unit;

[0009] The cigarette rack is a vertical rectangular frame structure; it is equipped with casters at the bottom; and it can be placed on a support platform.

[0010] Preferably, there are eight vertical guide rails, which are installed in four pairs inside the baking room. Two pairs are respectively located on the front and rear sides of the baking room, and the other two pairs are located close to each other in the middle of the baking room.

[0011] Preferably, the vertical guide rails are column-shaped structures with a height not less than half the height of the drying room; each pair of vertical guide rails has a guide groove on its opposite end face; the supporting platform extends into the guide groove for installation.

[0012] Preferably, the support platform includes a pair of parallel crossbeams; a base plate is provided between the two crossbeams; sliders are detachably provided on both sides of the crossbeams; the sliders are correspondingly installed on the vertical guide rails; and the base plate is used to place the cigarette holder.

[0013] Furthermore, connectors are installed on both sides of the crossbeam; the slider is detachably mounted on the connector via a bolt assembly.

[0014] Furthermore, a strip groove is provided on the base plate for the rollers of the cigarette holder to travel; the strip groove is arranged along the length of the base plate; and a limiting clip is also provided at the strip groove to restrict the movement of the cigarette holder.

[0015] Preferably, the electrically controlled drive component is an electro-hydraulic drive structure, which includes a hydraulic pump, a hydraulic lifting column, hydraulic oil pipes, and a motor; each carrying platform is equipped with two hydraulic lifting columns; these two hydraulic lifting columns are located in the gaps between the two sides of the carrying platform and the left and right side walls inside the baking oven; the hydraulic pump is connected to the hydraulic lifting columns through hydraulic oil pipes; a lifting plate is provided on the output end of the hydraulic lifting column; the lifting plate is located on the lower side of the carrying platform and is used to control the lifting action of the carrying platform.

[0016] Furthermore, the lifting plate is a U-shaped plate component; both ends of the lifting plate are connected to the output ends of the hydraulic lifting column, and the middle part is supported in the middle position of the bottom surface of the bearing platform.

[0017] Preferably, the rollers are omnidirectional wheels and are equipped with foot-operated brake pads; the smoke rack includes two opposing grid frames; the front and rear sides of the two grid frames are connected by upper and lower crossbars; a positioning crossbar is provided in the middle of the top side of the two grid frames; the height of the smoke rack does not exceed half the height of the curing barn.

[0018] The beneficial effects of this invention are reflected in the following aspects:

[0019] 1. This invention mechanizes the vertical lifting of the tobacco rack, which is filled with tobacco clips, from the ground to the target height by setting up a carrying platform driven by an electronically controlled lifting component, thus replacing manual labor of carrying heavy loads and climbing. Operators only need to hang the tobacco clips on the tobacco rack on the ground or at a low position, and then push the tobacco rack horizontally into the curing room, transforming the heavy and high-intensity physical labor into a light and convenient mechanized operation.

[0020] 2. A movable tobacco rack is used as a batch carrying unit for tobacco clips. During operation, multiple tobacco clips can be pre-loaded onto a tobacco rack outside the curing barn, and then lifted and pushed into the predetermined position by the carrying platform. This whole rack loading and unloading mode avoids loading tobacco in the relatively narrow space inside the curing barn, which greatly improves the efficiency of curing.

[0021] 3. Throughout the entire operation process, the core working area of ​​the operator is located on the ground or at a safe height, which completely avoids the risks of falls and injuries caused by climbing and imbalance of loads in traditional methods, and greatly ensures the safety of personnel.

[0022] 4. The strip grooves on the support platform ensure that all the tobacco leaves are kept at a consistent spacing and are neatly arranged in the curing barn, creating ideal conditions for the uniform and smooth circulation of hot air in the curing barn, which helps to improve the uniformity and overall quality of tobacco curing.

[0023] 5. The device integrates the vertical guide rail with the curing barn structure. The support platform can be raised and lowered along the guide rail. The rollers at the bottom of the smoke rack cooperate with the strip groove and limit clips on the base plate to realize easy movement and reliable fixation of the smoke rack on the support platform. The entire system has a compact layout and is particularly suitable for retrofitting and installing in existing dense curing barns.

[0024] 6. The vertical guide rail, the electrically controlled lifting assembly, and the standardized smoke rack all adopt a modular design; this facilitates the maintenance or replacement of the device; it eliminates the need to use the original smoke hanging beams in the curing barn, instead using the smoke rack directly as a support component in the curing barn for curing.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0029] Example:

[0030] Reference Figure 1 This embodiment provides a drawer-pull type smoke hood device; a drawer-pull type smoke hood device; it includes a drying room 1; characterized in that: a vertical guide rail 2, an electrically controlled lifting component and a smoke rack 3 are provided in the drying room 1;

[0031] Vertical guide rails 2 are fixed inside the drying room; there are at least four vertical guide rails 2, and these vertical guide rails are arranged in pairs close to the left and right side walls of the drying room 1; the paired vertical guide rails provide a solid and precise vertical movement track for the bearing platform, ensuring the stability and load-bearing capacity of the lifting process;

[0032] The electric lifting assembly includes a support platform 4 and an electric drive component 5; the left and right ends of the support platform 4 are respectively installed in the vertical guide rail 2, and the support platform 4 can move along the vertical guide rail 2 under the drive of the electric drive component 5; the support platform serves as an intermediate carrier connecting the smoke rack and the lifting power.

[0033] The smoke rack 3 is a vertical rectangular frame structure; rollers 6 are installed at the bottom of the smoke rack 3; the smoke rack 3 can be placed on the support platform 4. As an independent and movable smoke loading unit, the smoke rack realizes the batch management and handling of smoke clips, and the rollers at its bottom are the basis for easy pushing and pulling; the core of the device of this invention is to construct a liftable mechanized smoke loading platform, transforming the traditional high-altitude, decentralized operation into a ground-based, centralized assembly line operation.

[0034] There are eight vertical guide rails 2 in total, divided into four pairs and installed inside the curing barn 1. Two pairs are located on the front and rear sides of the curing barn 1, respectively, while the other two pairs are located close to each other in the middle of the curing barn 1. The curing barn is divided into two tobacco loading areas along its length. By using multiple pairs of guide rails corresponding to two support platforms, four tobacco racks can be arranged, which greatly improves the space utilization and tobacco loading efficiency of the curing barn.

[0035] The vertical guide rail 2 is a column-shaped structure, with a height not less than half the height of the drying chamber 1; each pair of vertical guide rails 2 has a guide groove on its opposite end face; the supporting platform 4 extends into the guide groove for installation. The design of the guide groove allows the slider of the supporting platform to slide within it, which not only serves as a guide but also restricts the lateral displacement of the platform, enhancing the torsional resistance and stability of the overall structure.

[0036] The support platform 4 includes a pair of parallel crossbeams 41; a base plate 42 is provided between the two crossbeams 41; sliders 43 are detachably provided on both sides of the crossbeams 41; the sliders are correspondingly installed on the vertical guide rails 2; the base plate 42 is used to place the smoke rack 3. The structural combination of the crossbeams and the base plate not only ensures sufficient load-bearing strength, but also reduces its own weight; the detachable slider design facilitates installation, debugging and maintenance.

[0037] Connectors 44 are installed on both sides of the crossbeam 41; the slider 43 is detachably mounted on the connector 44 via bolt assemblies. In this embodiment, the connector is a pair of ear plates; the connector serves as an adapter interface between the slider and the crossbeam, facilitating the assembly and disassembly of the slider, while optimizing the structural stress on the load-bearing platform itself.

[0038] A strip groove is provided on the base plate 42 for the rollers of the smoke rack 3 to travel; the strip groove is arranged along the length of the base plate 42; a limiting clip is also provided at the strip groove to restrict the movement of the smoke rack 3. The strip groove precisely guides the rollers of the smoke rack, ensuring that they move in a straight line when pushed in and pulled out, and are aligned with the preset smoke loading position in the curing barn; in this embodiment, the limiting clip is a plate-shaped component that is fastened to the lower side rod of the smoke rack, and the limiting clip can fix the smoke rack after it reaches the correct position, preventing accidental movement during lifting or curing.

[0039] The electro-hydraulic drive unit 5 is an electro-hydraulic drive structure, which includes a hydraulic pump, hydraulic lifting columns, hydraulic oil pipes, and a motor. Each carrying platform 4 is equipped with two hydraulic lifting columns. These two hydraulic lifting columns are located in the gaps between the two sides of the carrying platform 4 and the left and right side walls inside the curing barn 1. The hydraulic pump is connected to the hydraulic lifting columns through hydraulic oil pipes. A lifting plate 7 is installed on the output end of the hydraulic lifting column. The lifting plate 7 is located on the lower side of the carrying platform 4 and is used to control the lifting and lowering movements of the carrying platform 4. The electro-hydraulic drive can provide a smooth, strong, and controllable lifting force, which can meet the lifting and lowering requirements of tobacco curing operations. The lifting columns located on both sides work together to ensure the balance and synchronization of the lifting and lowering process of the carrying platform.

[0040] The lifting plate 7 is a U-shaped plate component; its two ends are connected to the output ends of the hydraulic lifting column, and its middle part is supported by the middle of the bottom surface of the bearing platform 4. The U-shaped lifting plate lifts the platform from the middle of the bottom. This central lifting method is conducive to the uniform distribution of force and can prevent the platform from tilting or jamming during the lifting process, making the lifting action more stable and reliable.

[0041] The rollers 6 are swivel casters and are equipped with foot-operated brake pads. The smoke rack 3 includes two opposing grid frames. The front and rear sides of the two grid frames are connected by upper and lower crossbars. A positioning crossbar is provided in the middle of the top side of the two grid frames. The height of the smoke rack 3 does not exceed half the height of the curing barn 1. The swivel casters allow the smoke rack to move flexibly in the loading area. The foot-operated brake pads can lock the smoke rack when needed to ensure operational safety.

[0042] When using the device of the invention in this embodiment, the following process can be referred to:

[0043] 1. Push the empty tobacco rack to a flat ground outside the curing barn or a designated loading area; the operator hangs the tobacco clips already filled with fresh tobacco leaves on the tobacco rack until the entire tobacco rack is filled.

[0044] 2. The bearing platform is reset by the electronically controlled drive components, causing it to descend to its lowest position;

[0045] 3. Release the brake pads of the smoke rack, manually push the fully loaded smoke rack along the ground to the bottom plate of the support platform, align the rollers at the bottom of the smoke rack with the strip groove on the bottom plate, then push the smoke rack completely into the support platform along the strip groove and fix it with the limit clips.

[0046] 4. Start the electric control drive to control the hydraulic lifting column to lift the lifting plate, thereby smoothly lifting the bearing platform and the fully loaded tobacco rack on it to the target tobacco loading layer height above the curing barn.

[0047] 5. After all the carrying platforms have delivered the tobacco racks full of tobacco clips to the upper level of the curing barn, push the remaining tobacco racks with the tobacco clips attached one by one onto the floor of the curing barn and lock them in place. After that, the tobacco curing operation can begin.

[0048] 7. After baking, the smoke unloading process is the reverse of the above steps; after pushing out the smoke racks on the ground, lower the support platform one by one, and push out the smoke racks located on the support platform.
