Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco baking, and particularly relates to an upper tobacco auxiliary device for a baking house. Background Art

[0002] Flue-cured tobacco modulation refers to putting multiple tobacco leaves into the interior of a baking house in a loading manner of being strung on a rod with a string, clamped by a tobacco clip or placed in a tobacco frame, and completing dehydration and internal chemical composition transformation after three-stage baking. At present, the existing technology uses the loading methods of tobacco rods and tobacco clips for tobacco leaves more, especially the former has a lower cost, so it has a wider application range. However, when loading tobacco into the baking house, since there are basically more than three shed frames inside the current baking house to support both ends of the tobacco rod to achieve the design purpose of making full use of space, the upper tobacco operation of the middle shed frame and the upper shed frame requires working at heights. For this reason, a variety of heightening devices have been designed in the existing technology. From the perspective of simplicity and practicality, the simplest step-type heightening platform has the advantages of taking into account both cost and structural strength. However, there are also the following problems in specific use: 1) Because the heightening platform has a certain mass, generally rollers are added at one end during movement to reduce the transfer difficulty, but it is easy to cause shaking when people and tobacco are on it; 2) The tobacco baking period is in the rainy season, so the floor of some bulk curing barns is designed with a waterproof threshold, resulting in inconvenience for the heightening platform to enter the door; 3) After the tobacco rods are strung with tobacco, the mass is relatively large, and when manually loading tobacco, it is necessary to repeatedly go up and down the steps to pick up the tobacco rods, and the overall labor intensity is high. Content of the Utility Model

[0003] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide an upper tobacco auxiliary device for a baking house. The utility model has a simple structure, is improved on the basis of the existing heightening platform in the prior art, and can greatly reduce the labor intensity and improve the upper tobacco efficiency.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] An upper tobacco auxiliary device for a baking house includes a heightening platform composed of a square bottom frame, triangular frames arranged on two length sides of the bottom frame, and several steps connecting the two triangular frames. The hypotenuses of the two triangular frames are arranged close to the side of the steps, and guardrails are provided at the tops of the hypotenuses. Chain wheels are rotatably provided at both ends of the guardrails, and the chain wheels and a chain form a chain wheel transmission structure for driving the tobacco rods strung with tobacco.

[0006] Preferably, the chain wheels at the bottoms of the two guardrails are connected by a wheel shaft, and a motor is further provided on the bottom frame on one side of the bottom of one guardrail. The output end of the motor is in transmission connection with the wheel shaft.

[0007] Preferably, several hanging rods are vertically arranged at equal intervals outside the chain.

[0008] Preferably, a roller mechanism is further provided at the corners of the bottom frame. The roller mechanism includes a circular wheel disc, and three support plates are integrally extended radially on the disc surface of the wheel disc. The support plates are of equal length and are arranged at equal circumferential intervals. The free ends of the support plates are rotatably connected with rollers.

[0009] Preferably, a telescopic sleeve is further provided beside the wheel disc. The top end of the telescopic sleeve is connected to the bottom surface of the bottom frame, and the bottom end is connected to the wheel seat. A spring is sleeved outside the telescopic sleeve between the wheel seat and the bottom frame. The wheel seat is rotatably connected to the wheel disc through a rotating shaft; a column foot is fixedly provided on the bottom surface of the bottom frame beside the telescopic sleeve; when the spring is in the state of minimum deformation, the bottom surface of the column foot is higher than the bottom surface of the roller below the wheel disc; when the spring is in the state of maximum deformation, the bottom surface of the column foot is at the same height as the bottom surface of the roller below the wheel disc.

[0010] Preferably, the wheel disc is arranged in the vertical plane outside the bottom frame.

[0011] The working process of the utility model is as follows:

[0012] During the transportation process of the utility model, it does not bear additional vertical pressure. The spring is only used to bear the self-weight of the whole machine. Therefore, at this moment, the deformation of the spring satisfies the height of the column foot from the ground. At this moment, the whole machine can move completely relying on the rolling of the rollers, and each wheel disc is in a state where two rollers are in contact with the ground and one roller is upward. When the roller touches the threshold, the wheel disc can rotate under the resistance effect, use the length of the support plate to cross the threshold, and make the original upper roller contact the ground downward, so that the high platform can enter the baking room without lifting.

[0013] When the high platform reaches the target position, a tobacco farmer can climb onto the high platform. His own weight compresses the spring again and makes the distance between the bottom frame and the ground smaller, so that the column foot touches the ground to bear the weight of the whole machine and prevent the high platform from shaking.

[0014] At the same time, another tobacco farmer on the ground starts the motor. The motor drives the two chains to rotate synchronously through the wheel shaft. At the same time, the tobacco farmer on the ground places the tobacco rod in an inclined state with one end high and one end low on the two chains (because the length of the tobacco rod is greater than the spacing of the shed frames, so it needs to be placed obliquely). During the rotation of the chains, the tobacco rod is lifted to the tobacco farmer on the high platform by using the hanging rod, and the tobacco farmer can lift the tobacco rod and hang it on the shed frame.

[0015] When the tobacco loading operation in the current area is completed, the tobacco farmer on the high platform can first move to the ground, and pull the utility model outward to move to a new area, and repeat the above actions for tobacco loading until the tobacco loading operations on the middle shed frame and the upper shed frame of the whole baking room are completed.

[0016] Compared with the prior art, the utility model has the following advantages: The structure of the utility model is simple. It is improved on the basis of the existing elevated platform, which is convenient for transportation and can be positioned after people get on it. At the same time, it can also assist in lifting the tobacco rod, greatly reducing the labor intensity and improving the tobacco loading efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a schematic structural diagram of the tobacco loading auxiliary device for the curing barn described in the specific embodiment;

[0018] Figure 2 is Figure 1 An enlarged structural diagram of part A in the shown device. SPECIFIC EMBODIMENTS

[0019] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0020] As Figure 1-2 shown, a tobacco loading auxiliary device for a curing barn includes an elevated platform composed of a square bottom frame 1, triangular frames 2 arranged on two long side edges of the bottom frame 1, and several steps of ladder platforms 3 connecting the two triangular frames 2.

[0021] The hypotenuses of the two triangular frames 2 are arranged against the side of the ladder platform 3, and guardrails 4 are provided at the tops of the hypotenuses. Sprockets 5 are rotatably provided at both outer ends of the guardrail 4, and the sprockets 5 and the chain 51 form a sprocket drive structure for driving the tobacco rods. Several hanging rods 52 are vertically arranged at equal intervals outside the chain 5. The sprockets 5 at the bottom ends of the two guardrails are connected by a wheel shaft 53, and a motor 54 is further provided on the bottom frame on one side of the bottom of one guardrail 4. The output end of the motor 54 is in transmission connection with the wheel shaft 53.

[0022] Roller mechanisms are further provided at the corners of the bottom frame 1. The roller mechanisms include circular discs 6 arranged in a vertical plane outside the bottom frame 1 and telescopic sleeves 64 arranged beside the discs 6. The top end of the telescopic sleeve 64 is connected to the bottom surface of the bottom frame 1, and the bottom end is connected to a wheel seat 63. The wheel seat 63 is rotatably connected to the disc 6 through a rotating shaft, and three support plates 61 are integrally extended radially on the disc surface of the disc 6. The support plates 61 are of equal length and are circumferentially arranged at equal intervals, and the free ends of the support plates are rotatably connected with rollers 62.

[0023] A spring 65 is sleeved outside the telescopic sleeve 64 between the wheel seat 63 and the bottom frame 1, and a column foot 11 is further fixed on the bottom surface of the bottom frame 1 beside the telescopic sleeve 64; when the spring 65 is in the state of minimum deformation, the bottom surface of the column foot 11 is higher than the bottom surface of the roller 62 below the disc 6; when the spring 65 is in the state of maximum deformation, the bottom surface of the column foot 11 is at the same height as the bottom surface of the roller below the disc 6.

[0024] The working process of the utility model is as follows:

[0025] During the transfer process of the utility model, it does not bear additional vertical pressure. The spring 65 is only used to bear the self-weight of the whole machine. Therefore, at this moment, the deformation of the spring 65 meets the height of the column foot 11 from the ground. At this moment, the whole machine can move completely by relying on the rolling of the rollers 62. Moreover, each wheel disc 6 is in a state where two rollers 61 are in contact with the ground and one roller is upward. When the roller 62 touches the threshold, the wheel disc 6 can rotate under the resistance effect, use the length of the support plate 61 to cross the threshold, and make the original upper roller 61 contact the ground downward, so that the high platform can enter the curing barn without lifting.

[0026] When the high platform reaches the target position, a tobacco farmer can step onto the high platform. His own weight compresses the spring 65 again and makes the distance between the bottom frame 1 and the ground smaller, so that the column foot 11 touches the ground to bear the weight of the whole machine and prevent the high platform from shaking.

[0027] At the same time, another tobacco farmer on the ground turns on the motor 54. The motor 54 drives the rotation of the two chain drives synchronously through the wheel shaft 53. At the same time, the tobacco farmer on the ground places the tobacco rod in an inclined state with one end high and one end low on the two chains 51 (because the length of the tobacco rod is greater than the spacing of the shed frames, so it needs to be placed obliquely). During the rotation of the chain 51, the hanging rod 52 is used to lift the tobacco rod to the tobacco farmer on the high platform, and the tobacco farmer can lift the tobacco rod and hang it on the shed frame.

[0028] When the tobacco loading operation in the current area is completed, the tobacco farmer on the high platform can first move to the ground, and pull the utility model outward to move to a new area, and repeat the above actions for tobacco loading until the tobacco loading operations on the middle shed frame and the upper shed frame of the whole curing barn are completed.
