Description

Technical Field

[0001] The utility model relates to the technical field of material drying, in particular to a hanging baking material carrying device. Background Art

[0002] In the traditional baking industry, it is still in the labor-intensive stage. With the development of the aging society, the young labor force is becoming less and less, and machines, automation and other equipment are constantly developing to cope with the phenomenon of reduced labor force.

[0003] In the baking industry, material handling is mainly done manually. When the materials are scattered and large, loading and unloading materials is a time-consuming and labor-intensive process. If ten times of handling can be reduced to one, it will greatly reduce working hours and manpower.

[0004] In many existing hanging ovens, it is not possible to hang all the materials on the hanger at once on the floor of the oven and then raise it for baking. Instead, it is necessary to climb up and hang the materials on the hanger one by one. This is because the hanger needs to be supported on the oven support beams and support frames, so the size of the hanger is larger than the baking interval formed by the support beams and support frames (the two ends of the hanger are supported on the oven support beams and support frames, and the materials on the hanger are located between the oven support beams and support frames). Therefore, if all the materials are hung on the hanger at once on the ground, the hanger cannot be raised above the oven support beams and support frames because its size is larger than the baking interval formed by the support beams and support frames, and it falls downward from the two ends of the hanger on the oven support beams and support frames.

[0005] For example, in the enterprise standard "Henan Tobacco Company Enterprise Standard-Air Source Heat Pump Intensive Curing Room" (Q / HNYC 050-2020), tobacco leaves are loaded and unloaded in a horizontal manner, and the overall loading and unloading will become difficult to operate. The overall loading and unloading can be completed in one time and the handling operation has to be divided into ten times of handling. The handling efficiency is very low and the labor consumption is very high.

[0006] Therefore, it is necessary to develop a material carrying device for hanging baking, which can vertically pass through the baking interval between the baking room support beam and the support frame, and can expand its own size after rising to the baking room support beam and the support frame so as to be erected on the baking room support beam and the support frame. Utility Model Content

[0007] The purpose of the utility model is to provide a material carrying device for hanging baking, which can vertically pass through the baking interval between the baking room support beam and the support frame, and can expand its own size after rising to the baking room support beam and the support frame so as to be erected on the baking room support beam and the support frame.

[0008] To achieve the above-mentioned purpose, the material carrying device for hanging baking of the utility model comprises a front frame, a rear frame and a cross frame connected between the front frame and the rear frame, the front frame and the rear frame are used to carry the materials to be baked, and the front frame, the rear frame and the cross frame are all square tube structures;

[0009] The left and right sides of the front frame are respectively provided with a left front telescopic rod and a right front telescopic rod.

[0010] The left and right sides of the rear frame are respectively provided with a left rear telescopic rod and a right rear telescopic rod.

[0011] The front frame and the rear frame are collectively referred to as a baking support tube, the left front telescopic rod, the right front telescopic rod, the left rear telescopic rod and the right rear telescopic rod are collectively referred to as telescopic rods, and the telescopic rods are movably sleeved in the baking support tube;

[0012] When the telescopic rod is retracted into the baking support tube to the inner limit position, the left and right overall length of the telescopic rod and the baking support tube is less than the baking interval between the baking room support beam and the support frame;

[0013] When the telescopic rod is extended back from the baking support tube to the outer limit position, the left and right overall length of the telescopic rod and the baking support tube is greater than the baking interval between the baking room support beam and the support frame.

[0014] The direction pointing to the middle of the length of the baking support tube is the inward direction, and the opposite direction is the outward direction;

[0015] The middle part or the inner end of the telescopic rod is downwardly connected with a connecting block, and the lower end of the baking support tube is provided with a bottom hole corresponding to the stroke of the connecting block, and the bottom hole provides a left and right movable space for the connecting block;

[0016] The connecting block extends downwardly out of the bottom hole and is fixedly connected with a slide rod, which extends in the left-right direction. The baking support tube is fixedly connected downwardly with a fixed sleeve, and the slide rod passes through the fixed sleeve and slides with the fixed sleeve. Two or more fixed sleeves are arranged at intervals.

[0017] The middle part of the front frame is fixedly connected downward with an articulated seat, the articulated seat is articulated with an arc-shaped plate with the arc top facing downward, the middle part of the arc-shaped plate is articulated with a transmission rod, the inner end of the sliding rod corresponding to the right front telescopic rod is fixedly connected with a transmission block, and the transmission rod is articulated with the transmission block;

[0018] When the arc-shaped plate moves downward, the transmission rod and the transmission block drive the right front telescopic rod to slide horizontally inward and retract into the front frame;

[0019] When the arc plate moves upward, the transmission rod and the transmission block drive the right front telescopic rod to slide outward horizontally and extend outward from the front frame;

[0020] The top of the inner end of the right front telescopic rod is connected to the left with a right front rack, a front gear is installed in the front frame just above the hinge seat, and the bottom of the inner end of the left front telescopic rod is connected to the right with a left front rack; the front gear is directly opposite to the cross frame;

[0021] The top of the front gear meshes with the right front rack and the bottom of the front gear meshes with the left front rack.

[0022] A rear gear is arranged in the rear frame and opposite to the front gear, and a transmission shaft is arranged in the cross frame, the front end of the transmission shaft is fixedly connected to the center of the front gear, and the rear end of the transmission shaft is fixedly connected to the center of the rear gear;

[0023] The top of the inner end of the right rear telescopic rod is connected to the right with a right rear rack, and the bottom of the inner end of the left rear telescopic rod is connected to the right with a left rear rack; the top of the rear gear is meshed with the right rear rack and the bottom of the rear gear is meshed with the left rear rack.

[0024] A load-bearing slot with an opening upward is arranged between the front frame and the rear frame, and clamping slots are connected downwardly at both ends of the length direction of the load-bearing slot, and the clamping slots are adapted to the front frame and the rear frame accordingly, and the load-bearing slot is clamped on the front frame and the rear frame from top to bottom through the clamping slots.

[0025] The outer end of each telescopic rod is respectively connected downwardly with an adjustment support block, which is used to support downwardly on the baking room support beam or support frame and form a vertical interval between the front frame and the rear frame and the baking room support beam or support frame.

[0026] Rollers are installed on the left and right ends of each baking support tube through a mounting seat. The bottom end of the roller is lower than the top wall of the corresponding baking support tube, and rolling friction is formed between the roller and the corresponding telescopic tube to reduce the friction when each telescopic rod is extended or retracted.

[0027] The utility model has the following advantages:

[0028] By adopting the structure of the utility model, when placing or hanging materials to be baked on the front rack and the rear rack, the telescopic rod can be retracted into the baking support tube to the inner limit position first, and the materials to be baked can be hung on the front rack and the rear rack on the floor of the baking room or placed on the front rack and the rear rack through the bearing groove, and then the material bearing device for hanging baking is used to rise to above the baking room support beam and the support frame at the baking interval between the baking room support beam and the support frame, and then each telescopic rod is extended out of the front rack and the rear rack to be erected on the baking room support beam and the support frame. In this way, the material loading work can be completed at one time on the ground, and there is no need to first erect the bearing device on the baking room support beam and the support frame and then load the materials thereon in multiple times (the bearing device cannot be filled at one time at a high place and needs to be climbed up and loaded one by one). Unloading can also be done by retracting the telescopic rods and dropping the material carrying device for hanging baking as a whole from the baking room support beams and support frames, and then completing all material unloading work on the ground at one time, without having to unload the materials on the carrying device one by one at a high place multiple times, thereby greatly improving the material loading and unloading efficiency and saving manpower.

[0029] The arrangement of the sliding rod, the fixed sliding sleeve and the connecting block ensures that each telescopic rod can stably slide left and right along the baking support tube.

[0030] The transmission structure such as the arc plate and the transmission rod can convert the up and down movement of the arc plate into the horizontal movement of the right front telescopic rod. The right front telescopic rod drives the left front telescopic rod to synchronously extend outward from the front frame or synchronously retract the front frame inward through the right front rack, the front gear and the left front rack, so that the operator can control the two telescopic rods at the front frame to synchronously extend outward from the front frame or retract them inward through the arc plate.

[0031] The arrangement of structures such as the transmission shaft can enable the left rear telescopic rod and the right rear telescopic rod to be driven by the transmission shaft and the rear gear and to be synchronously extended outward from the rear frame or retracted inward from the rear frame as the front gear rotates, so that the operator only needs to control the arc plate to rise to make all the telescopic rods synchronously extend outward from the baking support tube, and at the same time only needs to control the arc plate to fall to make all the telescopic rods synchronously retracted into the baking support tube.

[0032] The load trough facilitates drying of materials that are not suitable for hanging on the front and rear racks, especially bulk materials.

[0033] Adjusting the support blocks can form a vertical interval between the front frame and the rear frame and the baking room support beam or support frame, and when the bearing groove is used, interference between the clamping plates at both ends of the bearing groove and the baking room support beam or support frame can be avoided.

[0034] The roller can reduce the friction force when each telescopic rod is extended or retracted, which not only saves the resistance when pushing up or pulling down the arc plate, but also reduces the wear of each telescopic rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] like Figures 1 to 7 As shown, the material carrying device for hanging baking of the utility model (equivalent to the hanging rack) comprises a front frame 1, a rear frame 2 and a cross frame 3 connected between the front frame 1 and the rear frame 2, the front frame 1 and the rear frame 2 are used to carry the materials to be baked, and the front frame 1, the rear frame 2 and the cross frame 3 are all square tube structures; the left and right sides of the interior of the front frame 1 are movably sleeved with a left front telescopic rod 4 and a right front telescopic rod 5, and the left and right sides of the interior of the rear frame 2 are movably sleeved with a left rear telescopic rod 6 and a right rear telescopic rod 7,

[0043] The front frame 1 and the rear frame 2 are collectively referred to as a baking support tube, and the left front telescopic rod 4, the right front telescopic rod 5, the left rear telescopic rod 6 and the right rear telescopic rod 7 are collectively referred to as telescopic rods, which are movably sleeved in the baking support tube; each telescopic rod in the utility model is not telescopic by itself, but extends or retracts relative to the baking support tube.

[0044] As a preferred setting, rollers 9 are installed on the left and right ends of each baking support tube through a mounting seat 8 respectively. The bottom end of the roller 9 is lower than the top wall of the corresponding baking support tube, and rolling friction is formed between the roller 9 and the corresponding telescopic tube, which can reduce the friction force when each telescopic rod is extended or retracted, thereby saving resistance when pushing up or pulling down the arc plate and reducing the wear of each telescopic rod.

[0045] A roller 9 is preferably provided between the baking support tubes on the upper surface of each telescopic rod (the roller 9 is installed on), so that rolling friction can be formed between the telescopic rod and the baking support tube.

[0046] When the telescopic rod is retracted into the baking support tube to the inner limit position, the overall length of the telescopic rod and the baking support tube is less than the baking interval between the baking room support beam and the support frame. The baking room support beam and the support frame are prior art, and are used to support the baking bracket upward, i.e., the bearing device, which is not shown in the figure;

[0047] When the telescopic rod is extended back from the baking support tube to the outer limit position, the left and right overall length of the telescopic rod and the baking support tube is greater than the baking interval between the baking room support beam and the support frame.

[0048] By adopting the structure of the utility model, when placing or hanging the materials to be baked on the front frame 1 and the rear frame 2, the telescopic rod can be retracted into the baking support tube to the inner limit position first, and the materials to be baked can be hung on the front frame 1 and the rear frame 2 on the floor of the baking room or placed on the front frame 1 and the rear frame 2 through the bearing groove, and then the material bearing device for hanging baking is used to rise to above the baking room support beam and the support frame at the baking interval between the baking room support beam and the support frame, and then each telescopic rod is extended out of the front frame 1 and the rear frame 2 so as to be erected on the baking room support beam and the support frame. In this way, the material loading work can be completed at one time on the ground, and there is no need to first erect the bearing device on the baking room support beam and the support frame and then load the materials thereon in multiple times (the bearing device cannot be filled at one time at a high place and needs to be climbed and loaded one by one). Unloading can also be done by retracting the telescopic rods and dropping the material carrying device for hanging baking as a whole from the baking room support beams and support frames, and then completing all material unloading work on the ground at one time, without having to unload the materials on the carrying device one by one at a high place multiple times, thereby greatly improving the material loading and unloading efficiency and saving manpower.

[0049] The direction pointing to the middle position of the baking support tube in the length direction is inward, and the opposite direction is outward; the middle or inner end of the telescopic rod is downwardly connected to a connecting block 10, and a bottom hole is opened at the lower end of the baking support tube corresponding to the stroke of the connecting block 10, and the bottom hole provides a left and right activity space for the connecting block 10;

[0050] The connecting block 10 extends downwardly out of the bottom hole and is fixedly connected to a slide rod 11, which extends in the left-right direction. The baking support tube is fixedly connected downwardly to a fixed sleeve 12, and the slide rod 11 passes through the fixed sleeve 12 and slidably cooperates with the fixed sleeve 12; two or more fixed sleeves 12 are arranged at intervals.

[0051] The arrangement of the sliding rod 11, the fixed sliding sleeve 12 and the connecting block 10 ensures that each telescopic rod can stably slide left and right along the baking support tube.

[0052] The middle part of the front frame 1 is fixedly connected downward with an articulated seat 13, the articulated seat 13 is hinged with an arc plate 14 with the arc top facing downward, the middle part of the arc plate 14 is hinged with a transmission rod 15, the inner end of the slide rod 11 corresponding to the right front telescopic rod 5 is fixedly connected with a transmission block 16, and the transmission rod 15 is hinged with the transmission block 16;

[0053] When the arc plate 14 moves downward (rotates to the left), it drives the right front telescopic rod 5 to slide horizontally inward through the transmission rod 15 and the transmission block 16 and retracts into the front frame 1 (baking support tube);

[0054] When the arc-shaped plate 14 moves upward (rotates to the right), it drives the right front telescopic rod 5 to slide horizontally outward and extend outward from the front frame 1 through the transmission rod 15 and the transmission block 16;

[0055] The top of the inner end of the right front telescopic rod 5 is connected to the left with a right front rack 17, a front gear 18 is installed in the front frame 1 just above the hinge seat 13, and the bottom of the inner end of the left front telescopic rod 4 is connected to the right with a left front rack 19; the front gear 18 is opposite to the cross frame 3; the top of the front gear 18 is meshed with the right front rack 17 and the bottom of the front gear 18 is meshed with the left front rack 19.

[0056] The transmission structure such as the arc plate 14 and the transmission rod 15 can convert the up and down movement of the arc plate 14 into the horizontal movement of the right front telescopic rod 5, and the right front telescopic rod 5 drives the left front telescopic rod 4 to synchronously extend outward from the front frame 1 or synchronously retract the front frame 1 inward through the right front rack 17, the front gear 18 and the left front rack 19, so as to facilitate the operator to control the two telescopic rods at the front frame 1 to synchronously extend outward from the front frame 1 or retract inward through the arc plate 14.

[0057] A rear gear 21 is arranged in the rear frame 2 and opposite to the front gear 18, and a transmission shaft 20 is arranged in the cross frame 3. The front end of the transmission shaft 20 is fixedly connected to the center of the front gear 18, and the rear end of the transmission shaft 20 is fixedly connected to the center of the rear gear 21.

[0058] The top of the inner end of the right rear telescopic rod 7 is connected to the right rear rack 23, and the bottom of the inner end of the left rear telescopic rod 6 is connected to the left rear rack 22; the top of the rear gear 21 is meshed with the right rear rack 23 and the bottom of the rear gear 21 is meshed with the left rear rack 22.

[0059] The right rear rack 23, the left rear rack 22 and the rear gear 21 are symmetrically arranged with the right front rack 17, the left front rack 19 and the front gear 18, and the right rear rack 23, the left rear rack 22 and the rear gear 21 are not shown in the figure.

[0060] The arrangement of the transmission shaft 20 and other structures enables the left rear telescopic rod 6 and the right rear telescopic rod 7 to be synchronously extended outward from the rear frame 2 or retracted inward from the rear frame 2 under the drive of the transmission shaft 20 and the rear gear 21 along with the rotation of the front gear 18, so that the operator only needs to control the arc plate 14 to rise to make all the telescopic rods synchronously extend out of the baking support tube, and at the same time only needs to control the arc plate 14 to fall to make all the telescopic rods synchronously retracted into the baking support tube.

[0061] A load-bearing slot 24 with an opening upward is provided between the front frame 1 and the rear frame 2, and two ends of the load-bearing slot 24 in the length direction are connected downward with a clamping slot 25, and the clamping slot 25 is adapted to the front frame 1 and the rear frame 2, and the load-bearing slot 24 is clamped on the front frame 1 and the rear frame 2 from top to bottom through the clamping slot 25. The load-bearing slot 24 is convenient for drying materials that are not suitable for hanging on the front frame 1 and the rear frame 2, especially bulk materials.

[0062] The outer end of each telescopic rod is respectively connected downwardly with an adjustment support block 26, which is used to support downwardly on the baking room support beam or support frame and form a vertical gap between the front frame 1 and the rear frame 2 (i.e., the baking support tube) and the baking room support beam or support frame.

[0063] The adjusting support block 26 can form a vertical interval between the front frame 1 and the rear frame 2 and the baking room support beam or support frame, and can avoid interference between the clamping plates at both ends of the bearing groove 24 and the baking room support beam or support frame when the bearing groove 24 is used.

[0064] When in use, if the utility model is still in a high position (higher than the baking room support beam and the support frame), first pull the arc plate 14 downward, the arc plate 14 drives the right front telescopic rod 5 to retract inward through the transmission rod 15, the transmission block 16, the slide bar 11 and the connecting block 10, and the left front telescopic rod 4, the left rear telescopic rod 6 and the right rear telescopic rod 7 are synchronously retracted inward through the transmission action of the front gear 18, the rear gear 21 and the racks, so that the telescopic rods of the utility model are synchronously retracted. Since the overall size of each telescopic rod after retraction is smaller than the baking interval between the baking room support beam and the support frame, the utility model can fall without interference.

[0065] After it falls to the ground or a suitable height, loading can be carried out. When loading, the materials to be dried can be directly hung on the front rack 1 and the rear rack 2, or Figure 5 As shown, the material is placed in the bearing groove 24, and then the bearing groove 24 is set between the front frame 1 and the rear frame 2. Whether to directly hang the material or support the material through the bearing groove 24 is freely selected by the operator according to the specific type of the material to be dried and the principle of facilitating the drying operation.

[0066] The two ends of the bearing slot 24 in the length direction are connected downwardly with a clamping slot 25, and the clamping slot 25 is adapted to the front frame 1 and the rear frame 2. The bearing slot 24 is clamped on the front frame 1 and the rear frame 2 from top to bottom through the clamping slot 25. Figure 5 As shown, a plurality of card carrying slots 24 can be arranged side by side between the front frame 1 and the rear frame 2 .

[0067] After loading the materials, keep each telescopic rod in a retracted state, and lift the utility model carrying the materials to be dried upward from between the baking room support beam and the support frame. When it is higher than the baking room support beam and the support frame, the staff pushes the arc plate 14 upward, and the arc plate 14 drives the right front telescopic rod 5 to extend outward through the transmission rod 15, the transmission block 16, the slide bar 11 and the connecting block 10. Through the transmission action of the front gear 18, the rear gear 21 and each rack, the left front telescopic rod 4, the left rear telescopic rod 6 and the right rear telescopic rod 7 extend outward synchronously, so that each telescopic rod of the utility model extends synchronously. Since the overall size of each telescopic rod after being extended is larger than the baking interval between the baking room support beam and the support frame, the utility model can be conveniently erected on the baking room support beam and the support frame at this time. When the adjustment support block 26 is installed, the utility model is supported on the baking room support beam and the support frame through the adjustment support block 26 to form a certain support interval.
