Description

Technical Field

[0001] The utility model belongs to the technical field of small particle material transportation and relates to a self-dust suppression loading device. Background Art

[0002] With the acceleration of industrialization, more and more processing companies choose to transport materials in bulk, using powder tankers, container trucks and high-rail trucks to transport granular materials such as wheat, rice, corn, soybeans, and bran, rice husks, soybean meal, pellet feed, and impurities generated after raw grain processing. In recent years, with the continuous increase in bulk distribution, grain, feed and other processing companies with a certain scale have realized the hazards of dust during bulk distribution and the necessity of automated loading, and are gradually increasing or upgrading automatic loading systems. The past simple bag-loading and distribution has been eliminated, and retractable loading hoses and fixed dust suppression buckets, as the main equipment for bulk material distribution, have been increasingly recognized and used by the market.

[0003] At present, the best way to control dust by using loading hose when loading bulk materials is to reduce the height of the material exposed to the atmosphere by controlling the telescopic length of the hose, and at the same time, use the suction effect of the built-in pulse dust removal device or the external suction dust removal wind net to form negative pressure at the discharge port to prevent the dust in the material from overflowing and flying, thus playing a dust suppression role. However, since the material in the loading hose is limited by the discharge output of the upper equipment, the material is discharged directly from the inlet to the outlet and cannot fill the entire inner cylinder. The greater the height difference, the more serious the material falls and scatters, the greater the automatic classification of dust and materials, and the more serious the dust overflow. The negative pressure formed by the discharge port alone cannot completely suppress the dust from flying, and the environmental pollution problem in the workplace still exists. Especially when outdoor work encounters windy conditions, environmental pollution is even more serious.

[0004] The fixed dust suppression unloading hopper uses the weight of the material as the driving force, and forms a negative pressure material column through the change of the cross-sectional area of ​​the equipment, thereby effectively controlling the dust and material from being separated and blown out during bulk material loading and unloading. The advantage of this equipment is that it does not require external suction and has its own pulse dust collector, but due to the fixed installation height, it cannot meet the height requirements for loading vehicles of different specifications. In order to meet the requirements of the highest vehicle models to enter and exit without touching the equipment, the equipment installation height is often relatively high. Once the vehicle is loaded with a smaller vehicle, the dust suppression unloading hopper has a large drop from the discharge port to the car body, and the dust in the material flow quickly flies out after leaving the dust suppression unloading hopper and cannot be controlled, causing serious environmental pollution. Therefore, the current application of this loading method is very narrow, and its promotion and application is not large.

[0005] As national environmental protection requirements become increasingly stringent, how to effectively control dust spillage during bulk loading operations, protect the occupational health of operators, and save energy and reduce consumption has become one of the most concerned issues for users and urgently needs to be resolved.

[0024] The guide hopper group includes an upper fixed guide hopper 7-1, a movable guide hopper 7-2, and a lower fixed guide hopper 7-3 which are arranged in sequence from top to bottom. The upper fixed guide hopper 7-1 is fixedly installed on the upper part of the telescopic cloth cylinder 6.

[0025] The driving assembly includes a steel wire rope 5, which is arranged parallel to the side of the telescopic cloth tube 6. A mobile slide bar 7-21 is arranged on the outer periphery of the mobile guide hopper 7-2, the inner end of the mobile slide bar 7-21 is fixedly connected to the mobile guide hopper 7-2, the outer end of the mobile slide bar 7-21 passes through the telescopic cloth tube 6 and is slidably sleeved on the steel wire rope 5, and a fixed connecting rod 7-31 is arranged on the outer periphery of the lower fixed guide hopper 7-3, the inner end of the fixed connecting rod 7-31 is fixedly connected to the lower fixed guide hopper 7-3, and the outer end of the fixed connecting rod 7-31 passes through the telescopic cloth tube 6 and is fixedly connected to the steel wire rope 5.

[0026] The movable guide hopper 7-2 is supported by the movable slide rod 7-21 on the telescopic cloth tube 6 and is kept in the telescopic cloth tube 6. The lower fixed guide hopper 7-3 is supported by the fixed connecting rod 7-31 on the telescopic cloth tube 6 and is kept in the telescopic cloth tube 6.

[0027] The steel wire rope 5 is driven by a reduction motor 4, which is mounted on the side of the vehicle mounting frame 13. The output end of the reduction motor 4 is connected to the steel wire rope strand 3, and the top of the steel wire rope 5 is wound on the steel wire rope strand 3. The reduction motor 4 drives the steel wire rope 5 to be retracted or unfolded.

[0028] In this embodiment, the number of movable guide hoppers 7-2 is 3 and they are vertically arranged; the number of steel wire ropes 5 is 3.

[0029] The dust suppression discharge hopper 8 includes a nested discharge hopper fixed cover 9 and a discharge hopper movable cover 11. The discharge hopper fixed cover 9 is fixedly connected to the bottom of the telescopic cloth tube 6. The discharge hopper fixed cover 9 is connected to the discharge hopper movable cover 11 through a spring 10. A valve core 12 is provided between the discharge hopper fixed cover 9 and the discharge hopper movable cover 11.

[0030] The upper and lower ends of the spring 10 are respectively connected to the flange of the fixed cover 9 of the discharge hopper and the flange of the movable cover 11 of the discharge hopper.

[0031] The lower part of the fixed cover 9 of the discharge hopper and the upper part of the movable cover 11 of the discharge hopper are nested, ensuring that dust cannot flow out from the gap between the lower part of the fixed cover 9 of the discharge hopper and the movable cover 11 of the discharge hopper.

[0032] The valve core 12 includes a valve stem 12-1, which is fixedly connected to the discharge hopper fixed cover 9. A plug 12-2 is installed at the lower part of the valve stem 12-1. A discharge port is opened at the bottom of the discharge hopper movable cover 11. When no material is transported, the discharge hopper movable cover 11 is pulled by the spring 10, and the inner wall of the discharge hopper movable cover 11 sticks to the plug 12-2 to block the discharge port to prevent dust from overflowing from the discharge port.

[0033] In order to buffer the impact force of the materials on the movable cover 11 of the discharge hopper, a buffer plate 12-3 is installed on the upper part of the valve stem 12-1.

[0034] The working process of the utility model is as follows:

[0035] When the device is not working, the steel wire rope 5 is retracted to a retracted state, the upper fixed guide hopper 7-1, the movable guide hopper 7-2, and the lower fixed guide hopper 7-3 are stacked, and the telescopic cloth cylinder 6 is in a retracted state.

[0036] When starting work, the logistics vehicle drives to the bottom of the dust suppression discharge hopper 8, the steel wire rope 5 is unfolded under the drive of the reduction motor 4, and the dust suppression discharge hopper 8 moves down to the material bin of the vehicle. The gate above the feed port 1 opens and the equipment starts feeding. The material falls into the dust suppression discharge hopper 8 along the guide hopper 7. When the material in the discharge hopper movable cover 11 accumulates to the rated weight, the discharge hopper movable cover 11 pulls the spring 10 open under the action of gravity, and the plug 12-2 is separated from the discharge hopper movable cover 11, forming a discharge channel to achieve discharge.

[0037] Since the material in the dust suppression discharge hopper 8 is always full, the dust mixed in the material will not be automatically classified during the descent process in the sealed loading pipe, so the dust and material will not be lifted up and discharged from the dust suppression discharge hopper outlet together with the material column. The telescopic mechanism of the loading hose can ensure that the dust suppression discharge hopper outlet is always close to the material pile, which can minimize the overflow of dust and effectively control the dust pollution in the working environment. Since the material coming out of the dust suppression discharge hopper outlet is in a full column, there is no need to add an additional air suction and dust removal device when the equipment is working, which simplifies the dust suction function of the ordinary loading hose. The device has a large operating telescopic ratio when loading, which can meet the passage and loading of bulk vehicles of different heights and tonnage specifications.

[0038] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
