Description

Technical Field

[0001] The invention relates to the technical field of unloading equipment, and in particular to a vertical lifting and anti-coal-scattering environmentally friendly coal plow. Background Art

[0002] The coal plow, also known as the plow discharger, can realize the midway unloading of the belt conveyor and is widely used in the fields of power, port terminals, mining, metallurgy, etc. The working process of the coal plow is to use an electric push rod or other energy sources as the power source. The push rod drives the plow head to descend, and the lower edge of the plow head fits tightly with the belt surface, so that the material on the belt can be unloaded into the required place, which is referred to as "dropping the plow"; after the unloading is completed, the driving rod retracts, so that the plow board is lifted, allowing the material to pass smoothly, which is referred to as "lifting the plow".

[0003] For example, the utility model patent "A vertical lifting plow type discharger" with patent application number CN202020526773.4 (publication number CN212639063U) discloses a vertical lifting plow type discharger. When the plow type discharger needs to work, the electric push rod is turned on to make the electric push rod move downward. When the electric push rod pushes the driving frame to move downward, the driving frame drives the moving trolley to slide downward along the door frame through the connecting arm, and the main plow blade and the auxiliary plow blade on the driving frame move downward. At the same time, the driving frame belt The movable swing arm swings counterclockwise, and the swing arm pushes the sliding trolley to slide along the slide on the horizontal axis. The slide has a slope, and the front is low and the back is high. At this time, the sliding trolley slides backward as a whole, and the overall position of the sliding trolley moves upward relative to the door frame. At the same time, the first roller frame on the sliding trolley moves upward, and the first roller frame drives the flat roller and the roller in the middle of the grooved roller group to move upward. At this time, the flat roller contacts the conveyor belt, and the grooved roller group becomes a flat roller group, so that the space between the two grooved roller groups (i.e., below the main plow and the auxiliary plow) is )'s conveyor belt is always in a straight state, and the main coulter and the auxiliary coulter are always kept in good contact with the conveyor belt. The main coulter divides and discharges most of the materials, and the auxiliary coulter discharges the remaining materials again behind the main coulter, and the self-adjusting spring presses the auxiliary coulter to the conveyor belt to ensure that the auxiliary coulter is in full contact with the conveyor belt. When the auxiliary coulter is worn, it is automatically adjusted by the spring to ensure that the plow cleanliness of the unloader is greater than 99.9% and does not damage the conveyor belt; when it is necessary to stop unloading, the electric push rod is controlled to move upward, and the electric push rod drives the drive The frame moves upward, so that the main plowshare and the auxiliary plowshare move upward smoothly and separate from the conveyor belt. At the same time, the driving frame drives the swing arm to swing clockwise, and the swing arm pushes the sliding trolley to slide on the horizontal axis. At this time, the sliding trolley slides forward as a whole, and the overall position of the sliding trolley moves downward relative to the door frame, so that the first roller frame on the sliding trolley can move downward, and the first roller frame drives the flat roller and the roller in the middle of the trough roller group to move downward. At this time, the flat roller is separated from the conveyor belt, and the roller of the trough roller group becomes a trough-shaped support for the conveyor belt.

[0004] However, after the plow head of the above-mentioned coal plow is lifted, the coal materials on the conveyor belt are easily scattered to the ground due to inertia during the few seconds when the rollers of the trough roller group just become trough-shaped to support the conveyor belt. Summary of the invention

[0052] The plowshare 5 is arranged above the conveyor belt 4, and the plowshare 5 can be movably connected to the frame 1 up and down through the mounting seat 51. Specifically, two guide seats 511 corresponding to the above-mentioned guide columns 12 are arranged on both sides of the mounting seat 51, and the guide seats 511 are guided and matched with the corresponding guide columns 12.

[0053] There is a pair of drop hoppers 6, which are located on both sides of the conveyor belt 4.

A protective cover 62 is provided above the feed port 61 to prevent the upward airflow generated after the material enters the drop hopper 6 from causing material dust to overflow and pollute the environment.

[0054] The transmission assembly 7 is disposed between the plowshare 5 and the movable frame 2, and can transmit the movement of the plowshare 5 to the movable frame 2, so that the movable frame 2 moves relative to the fixed frame 11. In this embodiment, the transmission assembly 7 includes a first rotating shaft 71, a second rotating shaft 72 and a connecting rod 73.

[0055] The first driving member 8 is an electric push rod installed at the rear of the frame 1, and its power output end is connected to the plowshare 5 to drive the plowshare 5 to rise and fall.

[0056] There are two groups of anti-spill components 9, which correspond to the above-mentioned drop hoppers 6. Each anti-spill component 9 includes a baffle plate 91 and a flexible belt 92. Specifically, the baffle plate 91 is located behind the plowshare 5 and is hinged on the corresponding drop hopper 6. The baffle plate 91 can be tightly attached to the upper surface of the side of the conveyor belt 4 under the action of gravity, so that a material channel 10 is formed between the two baffle plates 91 and the conveyor belt 4. The diameter of the material channel 10 gradually decreases along the moving direction of the conveyor belt 4. In addition, the angle between the surface of the baffle plate 91 facing the material channel 10 and the upper surface of the side of the conveyor belt 4 is an obtuse angle, so as to prevent the baffle plate 91 from flipping upward under the reaction force of the material; the first end of the flexible belt 92 is connected to the second rotating shaft 72, and the second end is connected to the middle of the surface of the baffle plate 91 facing the material channel 10.

[0057] In addition, a basically horizontally arranged cover plate 13 is installed in the middle of the frame 1, and a clearance opening 131 for the following plowshare 5 to pass through is opened at the rear of the cover plate 13, and the cover plate 13 is in sealing contact with the plowshare 5; a basically vertically arranged curtain 14 is provided on the front side of the cover plate 13; the second driving member 15 is an electric push rod, which is installed at the front of the frame 1, and its power output end is connected to the top of the curtain 14 to drive the curtain 14 to rise and fall, and the curtain 14 can be raised and lowered synchronously or asynchronously with the plowshare 5.

[0058] The above-mentioned coal plow has at least two states when driven by the first driving member 8:

[0059] In the first state, if Figure 3 and Figure 4 As shown, the flat roller 32 and the grooved roller 34 are basically in the same horizontal plane, the conveyor belt 4 is basically arranged straight, the bottom of the plowshare 5 is against the upper surface of the conveyor belt 4, so as to discharge the material on the conveyor belt 4 into the hopper 6 through the feed port 61, the cover plate 13 is located on the top of the plowshare 5, the curtain 14 blocks the front side of the cover plate 13, and there is a gap between the bottom and the conveyor belt 4 for the material to pass through, and the relatively closed space formed by the plowshare 5, the cover plate 13, the curtain 14 and the conveyor belt 4 can prevent the material dust from overflowing and polluting the environment. At this time, the flexible belt 92 is in a relaxed state, and the bottom edge of the baffle plate 91 is close to the upper surface of the side of the conveyor belt 4, so as to prevent the material remaining on the conveyor belt 4 from being scattered from the side to the ground;

[0060] In the second state, if Figure 5 and Figure 6 As shown, the bottom of the plowshare 5 moves upward and away from the upper surface of the conveyor belt 4 under the drive of the first driving member 8, and drives the movable frame 2 and the flat roller 32 to move downward through the transmission assembly 7, so that the grooved roller 34 and the flat roller 32 form a certain angle (in this embodiment, the angle between the grooved roller 34 and the horizontal plane is about 35°), and the side of the conveyor belt 4 is bent upward. At this time, the flexible belt 92 is in a tensioned state, and the bottom edge of the baffle plate 91 is away from the upper surface of the side of the conveyor belt 4 to avoid scratching the upper surface of the conveyor belt 4, thereby extending the service life of both.

[0061] It is worth noting that during the process of the flexible belt 92 being transformed from a relaxed state to a tightened state, the bottom edge of the material baffle plate 91 is always in close contact with the upper surface of the side of the conveyor belt 4. During this period, the conveyor belt 4 basically remains in a horizontal state, and the upper surface of the conveyor belt 4 is covered with materials. Due to the effect of inertia, these few seconds are just the time for the coal plow to spread coal, and the material baffle plate 91 just prevents the material from falling to the ground, reducing the workload of maintenance staff, reducing maintenance costs and environmental pollution, and to a certain extent ensuring the health of operators and improving production efficiency.

[0062] The working principle of this embodiment is as follows:

[0063] (1) When the coal plow is unloading, Figure 3 and Figure 4As shown, the coal plow is in the first state, the flat roller 32 and the grooved roller 34 are basically in the same horizontal plane, the conveyor belt 4 is basically arranged straight, the bottom of the plowshare 5 is against the upper surface of the conveyor belt 4, so as to discharge the material on the conveyor belt 4 into the hopper 6 through the feed port 61, the cover plate 13 is located on the top of the plowshare 5, the curtain 14 blocks the front side of the cover plate 13, and there is a gap between the bottom and the conveyor belt 4 for the material to pass through, and the relatively closed space formed by the plowshare 5, the cover plate 13, the curtain 14 and the conveyor belt 4 can prevent the material dust from overflowing and polluting the environment. At this time, the flexible belt 92 is in a relaxed state, and the bottom edge of the baffle plate 91 is close to the upper surface of the side of the conveyor belt 4, so as to prevent the material remaining on the conveyor belt 4 from being scattered from the side to the ground;

[0064] (2) When it is necessary to stop unloading, it is only necessary to start the first driving member 8 to retract the electric push rod and drive the plowshare 5 to rise. During this process, the second rotating shaft 72 rises accordingly, thereby driving the connecting rod 73 to rotate around the axis of the first rotating shaft 71. Under the limiting action of the strip groove 7321 of the connecting rod 73, the movable frame 2 moves forward. Under the cooperation of the guiding inclined surface 22 and the roller 112, the movable frame 2 will synchronously descend during the forward movement, and the flat roller 32 will move down accordingly. Since the support frame 111 is always supported below the middle part of the second roller frame 33, the grooved roller 34 will form a certain angle with the flat roller 32. , so that the side of the conveyor belt 4 is bent upward and transformed into a groove angle form, until the guiding slope 22 is separated from the roller 112, and the movable frame 2 no longer descends. At the same time, the bottom edge of the baffle plate 91 is always close to the upper surface of the side of the conveyor belt 4, thereby preventing the material from being scattered to the ground due to inertia when the plow is lifted, until the flexible belt 92 is in a tensioned state, and then with the rise of the plow head 5, the second rotating shaft 72 is further lifted, and the baffle plate 91 is pulled further upward by the flexible belt 92 to make the bottom edge of the baffle plate 91 separate from the upper surface of the side of the conveyor belt 4, to avoid scratching the upper surface of the conveyor belt 4, thereby extending the service life of both.
