Description

Technical Field

[0001] The utility model relates to the technical field of road deicing, in particular to a device for continuously collecting and conveying ice debris. Background Art

[0002] As is known, an icebreaker is a common mechanical device for deicing roads. It is generally used in cold northern regions or important places such as airports that urgently need to de-ice quickly. It can efficiently and continuously de-ice while the icebreaker is moving. Usually, an icebreaker includes an ice-breaking device and an ice-crushing collection device. The ice-crushing collection device generally adopts a roller circular scraping method to scrape up the broken ice on the road surface and then turn it over to a conveyor chain for collection. However, this scraping collection method is relatively rough and is mainly used to collect large pieces of crushed ice. It is not clean for collecting small pieces of ice debris. In particular, in order not to damage the road surface, it cannot be collected close to the ground, resulting in incomplete collection, and the road surface will freeze into pieces again.

[0003] A Chinese utility model patent with announcement number CN2887951Y discloses a snowplow that uses vacuum suction to suck the accumulated snow into a snow storage box for collection. Although ice debris per unit volume is heavier than snow, this is also applicable to collecting small pieces of ice debris and can be fully applied to icebreakers for collecting ice debris. However, the problem is that the space in the snow storage box is limited, and how to continuously process the collected ice debris. The existing patent is to set a heater at the bottom of the snow storage box, melt the snow and then pump it out with a pump. Although the vacuum environment of the snow storage box is maintained, because ice debris is more difficult to melt than snow, and the collection speed needs to match the melting speed, the collection efficiency is low. In addition, in cold areas, the heater is affected by the external environment and the required energy consumption will also be very high. Utility Model Content

[0004] In order to overcome the deficiencies in the background technology and solve the existing technical problems, the utility model discloses a device for continuously collecting and conveying ice slag, which improves the collection and conveying efficiency and reduces energy consumption while ensuring vacuum collection.

[0005] In order to achieve the above-mentioned invention object, the utility model adopts the following technical solutions:

[0006] A device for continuously collecting and conveying ice debris comprises a collection box, wherein the upper part of the collection box is connected to a vacuum nozzle and a vacuum pump through a vacuum tube and an exhaust tube respectively; a downward outlet pipe is provided at the bottom end of the collection box, and a plug valve structure is installed on the outlet pipe.

[0007] Furthermore, the gate valve structure is configured as an automatic control valve, a pressure detector is installed on the top of the collection box, and the pressure detector is respectively connected to corresponding signals of the vacuum pump and the gate valve structure.

[0008] Furthermore, the gate valve structure includes a sliding gate, and channel steel-shaped slide rails symmetrically arranged on both sides of the middle of the outlet pipe and corresponding to the notches, the two sides of the sliding gate are respectively inserted into the two channel steel-shaped slide rails, and can move along the channel steel-shaped slide rails; the two channel steel-shaped slide rails both extend outward from the outlet pipe to form an extension portion, and a mounting plate is connected between the upper groove walls of the two channel steel-shaped slide rails corresponding to the extension portion, and a telescopic cylinder coaxial with the channel steel-shaped slide rail is installed on the mounting plate, and the telescopic end of the telescopic cylinder is correspondingly connected to the corresponding outer end of the sliding gate through a connecting seat to drive the sliding gate to move to achieve the closure or opening of the outlet pipe.

[0009] Furthermore, the sliding plug plate is configured as a heat conducting plate, an electric heating wire is hidden in the sliding plug plate, and a heating controller electrically connected to the electric heating wire is installed at the outer end of the sliding plug plate corresponding to the connecting seat.

[0010] Furthermore, a rotating shaft controlled to rotate by a motor is provided at the lower end of the outlet pipe, two ends of the rotating shaft are rotatably connected to two tube walls of the outlet pipe respectively, and a plurality of scrapers are evenly arranged around the shaft body of the rotating shaft.

[0011] Furthermore, the lower box wall of the collecting box connected to the outlet pipe is in a cone shape.

[0012] Furthermore, a rotating crushing roller is provided in the lower box wall of the collecting box.

[0013] Furthermore, the inner end cover of the exhaust pipe is covered with an ice shield, and a breathable mesh is provided on a side of the ice shield away from the inner end of the vacuum tube.

[0014] Furthermore, the lower port of the outlet pipe corresponds to a belt conveyor mechanism or an alternating transport vehicle.

[0015] Furthermore, the collection box is mounted on the ice-breaking vehicle body, and the vacuum suction nozzle corresponds to the ice-slag road surface.

[0016] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0017] The ice debris continuous collection and transportation device disclosed by the utility model arranges a gate valve structure at the bottom outlet pipe of the collection box. When the ice debris is just started to be sucked and collected, the gate valve structure is closed, and a vacuum pump is used to ensure the vacuum environment of the collection box. When the ice debris sucked into the collection box is affected by gravity and fills the outlet pipe, the gate valve structure is opened again to allow the ice debris to fall from the outlet pipe and be transported away. While the ice debris is continuously collected and transported, a part of the ice debris will always remain in the outlet pipe to play a sealing role, thereby ensuring the vacuum degree of the collection box. Compared with the prior art, the efficiency of ice debris collection and transportation is greatly improved, and energy consumption is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solution of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" and the like indicating directions or positional relationships, they are only corresponding to the drawings of the present invention, for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction: Embodiment 1:

[0022] Combined with Figure 1-2 The ice debris continuous collection and transportation device comprises a collection box 3, the upper part of which is connected to a vacuum nozzle 1 and a vacuum pump 6 through a vacuum tube 2 and an exhaust pipe 5 respectively, and the vacuum pump 6 is used to form a negative pressure inside the collection box 3, so that the vacuum nozzle 1 has sufficient suction force to absorb the ice debris; as needed, the inner end of the exhaust pipe 5 is covered with an ice shield 4, and a breathable mesh is provided on the side of the ice shield 4 away from the inner end of the vacuum tube 2 to prevent the ice debris from being directly sucked into the vacuum pump 6, so that the ice debris can fall naturally under the influence of gravity after entering the collection box 3 and bonding;

[0023] A downward outlet pipe 9 is provided at the bottom end of the collecting box 3, and a gate valve structure is installed on the outlet pipe 9; according to needs, the gate valve structure is set as an automatic control valve, and a pressure detector 7 is installed on the top of the collecting box 3, and the pressure detector 7 is respectively connected with the vacuum pump 6 and the gate valve structure corresponding to the signal, and the pressure detector 7 is used to detect the pressure in the collecting box 3. The signal feedback of the pressure detector 7 and the vacuum pump 6 can ensure the negative pressure in the collecting box 3 is stable, and the signal feedback of the pressure detector 7 and the gate valve structure can ensure that the outlet pipe 9 does not cause excessive pressure release. If there is too little ice accumulation, the gate valve structure can be controlled to close in time; in addition, the gate valve structure includes a sliding gate 12, and a channel steel slide rail 11 symmetrically arranged on both sides of the middle of the outlet pipe 9 and corresponding to the notch. The slide rail 11 divides the outlet pipe 9 into two upper and lower sections. The two sides of the sliding plug plate 12 are respectively inserted into the two grooved steel slide rails 11 and can move along the grooved steel slide rails 11; the two grooved steel slide rails 11 extend outward from the outlet pipe 9 to form an extension portion, and the extension portion has the function of preventing the sliding plug plate 12 from detaching. A mounting plate is connected between the upper groove walls of the two grooved steel slide rails 11 corresponding to the extension portion, and a telescopic cylinder 13 coaxial with the grooved steel slide rail 11 is mounted on the mounting plate. The telescopic cylinder 13 can be set as an electric control cylinder. The telescopic end of the telescopic cylinder 13 is correspondingly connected to the corresponding outer end of the sliding plug plate 12 through the connecting seat 14 to drive the sliding plug plate 12 to move to achieve the closure or opening of the outlet pipe 9, that is, when the telescopic cylinder 13 is extended, the outlet pipe 9 is opened, and when it is retracted, the outlet pipe 9 is closed;

[0024] In order to prevent ice debris from remaining in the groove of the channel steel slide rail 11 and causing the sliding plug plate 12 to move poorly, the sliding plug plate 12 is configured as a heat conduction plate, an electric heating wire is hidden in the sliding plug plate 12, and a heating controller 15 electrically connected to the electric heating wire is installed at the outer end of the sliding plug plate 12 corresponding to the connecting seat 14. The sliding plug plate 12 is heated by the electric heating wire, so that ice debris at the plug plate valve structure is not easy to stick, ensuring that the sliding plug plate 12 will not be hindered in pulling out.

[0025] In the implementation of the ice debris continuous collection and transportation device of the utility model, the collection box 3 is generally set up on the body of the ice-breaking vehicle, and the vacuum suction nozzle 1 corresponds to the ice debris road surface. As the ice-breaking vehicle moves, ice is broken and collected all the way, and the lower end of the outlet pipe 9 corresponds to a longer belt conveyor mechanism 16, or there are many vehicles that follow the ice-breaking vehicle to move and can alternately take over the ice debris to transport the discharged ice debris out in time. Usually, on the road surface of an airport with a larger area, it is impossible to discharge it sideways, and such long-distance transportation is required; by arranging a gate valve structure at the outlet pipe at the bottom end of the collection box 3, the gate valve structure can be closed when the ice debris is just being sucked and collected, and the vacuum environment of the collection box 3 is guaranteed by the vacuum pump 6, and when the ice debris sucked into the collection box 3 is affected by gravity and gathers in the outlet pipe 9, the gate valve structure is opened again, so that the ice debris can fall from the outlet pipe 9 and be transported away, and while the ice debris is continuously collected and transported, a part of the ice debris will always remain in the outlet pipe 9 to play a blocking role, thereby ensuring the vacuum degree of the collection box 3. Embodiment 2:

[0026] The difference from the first embodiment is that a rotating shaft 10 controlled by a motor is provided at the lower end of the outlet pipe 9, and the two ends of the rotating shaft 10 are rotatably connected to the two tube walls of the outlet pipe 9 respectively, and a plurality of scrapers 17 are evenly arranged around the shaft body of the rotating shaft 10. The rotating scrapers 17 ensure smooth discharge of ice debris from the outlet pipe 9; as needed, the lower box wall of the collecting box 3 connected to the outlet pipe 9 is in a cone shape, and the outlet gradually shrinks, which can reduce the accumulation of ice debris and realize the self-sealing effect of ice debris in advance; in addition, a rotating crushing roller 8 is provided in the lower box wall of the collecting box 3. If the ice debris is collected and discharged slowly, or the temperature is too low, causing the ice debris to stick together in advance, the cone-shaped gradual structure may also cause the ice debris to be unable to be discharged. The sticky ice debris can be broken up again by rotating the crushing roller 8, and the ice debris can be squeezed to fall.
