Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco processing auxiliary equipment, and in particular relates to an automatic tobacco falling material collecting vehicle. Background Art

[0002] In the process of tobacco processing, tobacco shedding is inevitable. For example, operators may make mistakes during the preparation of tobacco, causing tobacco or other ingredients to accidentally fall to the ground or around the machine. The operation of the tobacco-making equipment may be affected by various factors, such as vibration, mechanical failure, etc., which may cause tobacco or other ingredients to fall off the equipment and fall to the ground. In addition, tobacco may become unstable during processing due to changes in humidity, temperature or other factors, causing some tobacco to fall off the equipment or conveying system. In order to avoid waste and production interruptions caused by tobacco shedding, corresponding measures are usually required. In addition to regular inspection and maintenance of equipment and continuous optimization of the silk-making process, collection measures for tobacco shedding are also required.

[0003] The automatic collection of tobacco material in the prior art usually adopts the following methods: (1) This system uses airflow to blow the tobacco material to a centralized collection point. However, the strength and direction of the airflow need to be precisely controlled, otherwise the tobacco may be scattered or accumulated in inappropriate places. It is necessary to design a suitable pipeline layout to ensure that all parts can be effectively cleaned; (2) Vibration is used to transport the tobacco material from the surface of the equipment to a centralized collection point. However, the vibration mechanism is easily affected by pollutants such as smoke and dust, and needs to be cleaned and maintained regularly, otherwise it may cause system failure, and the vibration frequency and amplitude need to be precisely controlled to ensure that the tobacco can be transported evenly and avoid excessive vibration to damage the equipment. Noise and vibration require measures to reduce noise and vibration; (3) A conveyor belt is used to transport the tobacco material to the collection point. However, smoke and other impurities are easily accumulated on the surface of the conveyor belt, and it needs to be cleaned and maintained regularly, otherwise it may affect the transmission efficiency. The speed and direction of the conveyor belt need to be adjusted according to production needs, and the conveyor belt layout needs to consider the spatial layout of the production line.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, but cannot be construed as limiting the technical solution of the present invention.

[0025] The present application provides an automatic tobacco collection vehicle, comprising a sorting equipment frame 1, a collector 2, a suction system 3 and a collection barrel 4. Figure 1As shown, a collector 2 is installed under the chassis of the sorting equipment rack 1, and a suction system 3 and a collection bucket 4 are installed above the chassis of the sorting equipment rack 1. Among them, the sorting equipment rack 1 can adopt any existing intelligent vehicle, for example, a security patrol robot car with a wire-controlled chassis, or a vision-based OriginCAR model intelligent robot car, etc. The above-mentioned sorting equipment rack 1 is an existing technology, and only serves as a platform in this technical solution, and does not involve improvements to the sorting equipment rack. For this reason, the structure, control method, etc. of the sorting equipment rack are not described in this embodiment, which does not affect the implementation of the technical solution of this application. Those skilled in the art can obtain any model of device through commercial channels as needed.

[0026] like Figure 2 and Figure 3 As shown, the collector 2 includes a fixed cover 21, a lifting cylinder 22, a connecting rod 23, a slider 24, a main tension spring 25, an outer cover 26, an inner cover 27, an auxiliary tension spring 28 and a suction pipe 29. The fixed cover 21 is a cylindrical or square column structure, and a plurality of connecting rods 23 are evenly hinged around the inner wall of the fixed cover 21, and the bottom of each connecting rod 23 is hinged to the lifting cylinder 22. In other embodiments of the present application, a slide groove can be provided on the inner wall of the fixed cover 21 and a slider 24 can be installed, and a hinge seat is provided on the slider 24 for connecting the connecting rod 23, so that the lifting cylinder 22 has a large swing freedom.

[0027] The top of the lifting cylinder 22 is connected to the top of the fixed cover 21 through the main tension spring 25. An outer cover 26 is fixed to the bottom of the lifting cylinder 22. The upper part of the outer cover 26 is conical, and an inner cover 27 is mounted inside the outer cover 26. The upper part of the inner cover 27 is also conical. The bodies of the outer cover 26 and the inner cover 27 are respectively disc-shaped covers, but the diameter of the inner cover 27 is smaller than that of the outer cover 26, so that an annular area is formed between the outer cover 26 and the inner cover 27. An upwardly protruding top plate is arranged at the center of the inner cover 27. An auxiliary tension spring 28 is connected between the top plate and the inner top wall of the lifting cylinder 22. The elastic force of the auxiliary tension spring 28 is smaller than that of the main tension spring 25. A suction pipe 29 is installed on the top plate. The lumen of the suction pipe 29 is connected to the inner lumen of the inner cover 27. After the inner cover 27 passes through the top plate of the lifting cylinder 22 and the top plate of the fixed cover 21 upward, it is connected to the lower box of the collecting barrel 4.

[0028] The air duct of the suction system 3 is connected to the upper box of the collection barrel 4, and a filter layer is arranged between the upper box and the lower box of the collection barrel 4. A conical guide cover is arranged at the bottom of the lower box of the collection barrel 4, and a discharge port is arranged at the bottom of the collection barrel 4.

[0029] An annular outer rubber plate is provided at the bottom outer edge of the outer cover 26, and the outer edge of the outer rubber plate is tilted upward. An annular inner rubber plate is provided at the bottom outer edge of the inner cover 27.

[0030] The outer side of the fixed cover 21 is fixed to the chassis of the sorting equipment frame 1 through a bracket 5. The bracket can be a bracket 5 with adjustable height. If it is a bracket 5 with adjustable height, it includes a slide 51, an L-shaped fixing piece 52 and a locking wire 53. A series of vertical slides 51 are evenly arranged around the outer side of the fixed cover 21. Each L-shaped fixing piece 52 includes a horizontal plate and a vertical plate. The vertical plate of each L-shaped fixing piece 52 is matched and fitted in the corresponding slide 51. A locking wire 53 is installed on each vertical plate. After adjusting the height of the vertical plate in the slide 51, the height is fixed by turning the knob locking wire 53. Thus, it is ensured that the outer cover 26 has an appropriate height from the ground, so that the outer rubber plate at the bottom of the outer cover 26 maintains a matching gap with the ground.

[0031] Based on the above scheme, when the sorting equipment frame 1 moves in the area of ​​the tobacco silk workshop where materials are easily dropped, the outer cover 26 realizes negative pressure suction in a manner close to the bottom plate, and the gap between the outer cover 26 and the bottom plate is constantly changing, so that the airflow velocity caused by the negative pressure can be changed. When the gap between the outer cover 26 and the ground becomes smaller, in this case, the feed amount is small but the airflow velocity is high, and the airflow pressure is large; when the gap between the outer cover 26 and the ground becomes larger, the airflow velocity is low but the feed amount is large. This negative pressure suction method that constantly changes the gap between the outer cover 26 and the ground has the function of adaptively sucking scattered and accumulated tobacco of different thicknesses. Further combined with the elastic lifting performance of the inner cover 27, since the lifting frequency and amplitude of the inner cover 27 are different from those of the outer cover 26, the volatility of the negative pressure to the outside world is aggravated. When both the outer cover 26 and the inner cover 27 are in contact with the ground, the negative pressure in the inner cover 27 is the greatest, thereby being able to increase the ultimate negative pressure level; when the outer cover 26 or the inner cover 27 is in the process of changing from being in contact with the bottom surface to having a gap with the ground, the negative pressure state is suddenly released, causing the accumulated tobacco to be instantly sucked into the outer cover 26 or the inner cover 27, avoiding the problem of the tobacco moving with the cover body due to material jamming.

[0032] In the process of using the automatic collection vehicle for tobacco falling materials, first ensure that the automatic collection vehicle for tobacco falling materials is in normal working condition, all parts are fully installed and firmly connected, check the status of the suction system and the collection barrel to ensure that there is no blockage or leakage. Then start the intelligent vehicle on the sorting equipment frame 1 to ensure that the vehicle can walk and operate normally. Adjust the gap between the outer cover 26 and the ground as needed to control the airflow rate and feed amount. Ensure that the matching gap between the outer cover 26 and the ground is appropriate to achieve the best suction effect. Start collecting: Move the automatic collection vehicle for tobacco falling materials to the area that needs to be cleaned, ensure that the vehicle can cover the falling material area, and when the vehicle is moving, the collector 2 starts working and uses the suction system 3 to absorb the tobacco shreds that fall on the ground. The gap between the outer cover and the ground can also be adjusted at any time according to the actual situation to adapt to the accumulation of tobacco shreds of different thicknesses. If necessary, adjust the route and speed of the vehicle to ensure that the falling material area is fully cleaned. When the cleaning work is completed, stop the operation of the vehicle, turn off the suction system 3, check the collection situation of the collection barrel 4, and clean and process the collected tobacco shreds. In addition, it is necessary to regularly clean and inspect the collector 2, suction system 3 and collection barrel 4 to ensure the normal operation of each component, promptly handle any faults or problems, and keep the equipment in good condition. This will enable the automatic tobacco collection vehicle to be effectively operated and utilized, improve cleaning efficiency, and keep the working environment clean.

It should be pointed out that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Moreover, after reading the contents of the present invention, relevant technical personnel in the field can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
