For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0033] This embodiment describes a coal shoveling device, which can be used to collect residual coal in a carriage of a thermal power plant, can prevent the bucket and the carriage from being damaged by solid obstacles during the coal shoveling process, and can quickly collect the shoveled coal.
[0034] like Figure 1 As shown, the coal shoveling device includes a bucket 100, a lifting mechanism 200 and a coal storage box 300. The bucket 100 is installed at the lower front end of the coal storage box 300, and the lifting mechanism 200 is installed at the middle of the front end of the coal storage box 300 on the upper side of the bucket 100. The bucket 100 scoops up the coal and delivers the coal into the coal storage box 300 through the lifting mechanism 200.
[0035] like Figure 2 and Figure 3 As shown, the bucket 100 of this embodiment is a flexible lifting mechanism that can adaptively run close to the bottom of the vehicle body according to the shape of the bottom of the vehicle body. The bucket 100 includes a shovel plate 110, an elastic mechanism 120, a rotating shaft 130, a roller 140 and a baffle 150.
[0036] The rotating shaft 130 is installed at the lower front end of the coal storage box 300 and can rotate. The left and right ends of the top of the shovel plate 110 are respectively fixed to the left and right ends of the rotating shaft 130, and a plurality of rollers 140 are distributed at intervals on the bottom edge of the shovel plate 110.
[0037] On the outside of the coal storage box 300, both ends of the rotating shaft 130 are respectively connected to the elastic mechanism 120. The elastic mechanism 120 of this embodiment includes a pressing plate 121, a spring 122 and a spring guide column, the spring guide column is installed at the bottom of the coal storage box 300, the spring 122 is sleeved on the spring guide column, one end of the pressing plate 121 is fixedly connected to the rotating shaft 130, and the other end is sleeved on the spring guide column, pressed on the spring 122 and fixed by a locking nut.
[0038] During the coal shoveling process, due to the action of the elastic mechanism 120, the shovel plate 110 always runs close to the bottom of the car. When the front end of the shovel plate 110 encounters a fixed obstacle such as a solid obstacle or a step obstacle, the shovel plate 110 is automatically lifted up under the action of the roller 140, and the rotating shaft 130 rotates clockwise. The pressure plate 121 compresses the spring 122, so that the bucket 100 passes through the obstacle smoothly. Then, the pressure plate 121 drives the rotating shaft 130 to rotate counterclockwise under the elastic force of the spring 122, driving the shovel plate 110 to automatically press down and run close to the bottom of the car.
[0039] The baffle 150 of this embodiment is an arc-shaped plate, and its arc-shaped groove faces upward, below the lifting mechanism 200, and is used to temporarily store the coal scooped up by the bucket 100. The front end of the baffle 150 is installed at the front end of the coal storage box 300 below the rotating shaft 130, and is located below the top of the shovel plate 110, and the rear end is fixed on the coal storage box 300 near the coal storage area. The coal scooped up by the shovel plate 110 falls into the arc-shaped groove area of the baffle 150, and is taken away by the lifting mechanism 200 and sent into the coal storage box 300. In this embodiment, because the baffle 150 is inserted below the top of the shovel plate 110, it can ensure that the coal on the shovel plate 110 falls into the groove of the baffle 150.
[0040] The lifting mechanism 200 includes a driving motor, a driving roller 210, a driven roller 220, a chain plate 230 and a transport bucket 240. The driven roller 220 and the driving roller 210 are arranged in parallel and spaced apart in the middle of the front end of the coal storage box 300. The chain plate 230 surrounds the driving roller 210 and the driven roller 220 to form an annular chain plate, and a plurality of transport buckets 240 are evenly spaced and fixed on the outside of the annular chain plate, and the opening of the transport bucket 240 faces upward in the front end direction of the coal storage box 300, and faces downward in the rear end direction of the coal storage box 300. Below the lifting mechanism 200, a predetermined distance is left between the transport bucket 240 and the baffle 150. The driving motor is installed on the coal storage box 300 and is connected to the active roller 210. The driving roller 210 drives the chain plate 230 to rotate clockwise. When the transport bucket 240 passes through the arc-shaped groove area of the baffle 150, the transport bucket 240 scoops up the coal in the arc-shaped groove under the push of the rotation force of the chain plate 230, and is gradually lifted to the top of the lifting mechanism 200 along with the chain plate 230. When the transport bucket 240 moves downward and flips downward along with the sedimentation area 360, the coal in the transport bucket 240 is poured into the coal storage box 300 through the pouring port 310 under the action of gravity and inertia.
[0041] The coal storage box 300 has a temporary storage function after the residual coal in the carriage is cleaned. Figure 4 and Figure 5 As shown, the coal storage box 300 of this embodiment includes a dumping port 310 , a first inclined plate 330 , a second inclined plate 340 and a discharge door 350 .
[0042] A vertical plate is provided inside the coal storage box 300 to divide the inside of the coal storage box 300 into two parts, front and rear. The front part of the coal storage box 300 is a lifting mechanism installation area 320, which is the installation area of the lifting mechanism 200. The rear part of the coal storage box 300 is a coal storage area.
[0043] The vertical plate is provided with a discharge port 310 at the lower part of the position where the upper transport bucket 240 of the lifting mechanism 200 turns over from top to bottom. When the transport bucket 240 turns over, the coal is poured into the coal storage area of the coal storage box 300 through the discharge port 310 .
[0044] A discharge port is provided on the outer side of the bottom surface of the coal storage area. The discharge door 350 is a cylinder-driven door installed on the discharge port for opening and closing the discharge port. A sealing strip is provided on the bottom surface of the discharge port. When the discharge door 350 closes the discharge port, the sealing strip is pressed to achieve sealing at the discharge port. The discharge door 350 always closes the discharge port during the coal collection process. When the coal storage area is full or cleaned, the discharge door 350 opens the discharge port for coal unloading.
[0045] The coal shoveling device of this embodiment may further include a negative pressure adsorption device for sucking up the remaining coal shoveled by the bucket 100, which is installed at the rear side of the bucket 100. At this time, the rear part of the coal storage box 300 includes a coal storage area and a settling area 360, and the settling area 360 is located above and on both sides of the coal storage area.
[0046] The coal storage area includes a front coal storage area and a rear coal storage area, and the front coal storage area and the rear coal storage area are internally connected. A first inclined plate 330 is installed at the top of the front coal storage area. The first inclined plate 330 is inclined downward from front to rear, and its side can be a vertical plate or an inclined plate inclined outward from top to bottom. The top surface of the rear coal storage area is composed of two second inclined plates 340 connected symmetrically. The two second inclined plates 340 are inclined downward from the middle of the top surface of the rear coal storage area to the sedimentation areas 360 on the left and right sides respectively. The discharge port is set at the bottom of the rear coal storage area. The design of the inclined plate and the inclined surface facilitates the coal to fall to the discharge port after settling.
[0047] The settling area 360 is the settling area of the coal, and the suction pipe outlet of the negative pressure adsorption device is located at the upper part of the settling area 360. In this embodiment, the bottom surface of the settling area 360 located on both sides of the coal storage area is a slope that slopes downward from front to back, and the bottom end of the settling area 360 is connected to the discharge port. The adsorbed coal settles by gravity in the settling area 360 and is discharged through the discharge port.
[0048] The coal shoveling device of this embodiment is usually used for cleaning operations after unloading coal in a carriage (the materials carried in the carriage may also be other powders, particles, blocks, etc. similar in shape to coal, such as sand and gravel). Figure 3 As shown, the coal shoveling device moves to the left, and the bucket 100 uses the shovel plate 110 to shovel the remaining coal accumulated at the bottom of the carriage, and sends the coal into the coal storage box 300 through the lifting mechanism 200. When the coal storage box 300 is full or cleaned, the discharge port is opened to discharge the coal.
