In the existing track construction, gravel is often laid while moving by transport vehicles. The amount of gravel unloading cannot be controlled by the moving speed, resulting in uneven gravel unloading and uneven gravel paving, which requires further leveling by manual labor.

The present invention arranges the unloading mechanism, and when laying gravel, the gravel enters the unloading bin at a constant feeding speed, and the gravel will roll toward the discharge port. At this time, the gravel can be blocked by the unloading piece on the rotating shaft and will not fall directly from the discharge port. In the process of rotating the rotating shaft, the gravel between two adjacent unloading pieces will be pushed out from the discharge port, and the unloading amount of the gravel entering the unloading bin is controlled by the accommodation capacity of the gap between the adjacent unloading pieces. When the first synchronous wheel is rotated so that the first synchronous belt drives the third synchronous wheel to rotate, the second synchronous wheel can drive the fourth synchronous wheel to rotate together through the second synchronous belt. At this time, the driving shaft drives the two rear wheels to rotate together, so that the whole equipment moves on the track construction road surface, and quantitative unloading is carried out while moving, thereby making the gravel unloading relatively uniform, reducing the unevenness of gravel paving, and improving the efficiency of gravel paving.

The present invention sets a screening mechanism. When gravel enters the interior of the discharge bin through the feed port, the gravel will first pass through the first screen to screen gravel exceeding a specified range. The gravel that passes through the first screen and enters the interior of the discharge bin will contact the third screen and roll on the third screen. During the rolling process, the gravel will pass through the third screen to screen gravel smaller than the specified range, thereby ensuring that the laid gravel meets the specified size, avoiding large differences in gaps between the laid gravel, and improving the service life of the rails.

The present invention arranges a cleaning mechanism and a feeding mechanism, so that the crushed stones that pass through the first screen and enter the discharge bin will hit the third screen. The crushed stones that keep falling make the third screen drive the first piston plate to move back and forth inside the regulating bin, so that the air pressure inside the transfer bin is gradually strengthened, so that the second piston plate moves inside the transfer bin toward the direction of the sliding member, so that the crushed stones on the first screen move to the second screen and roll into the feed bin, so as to prevent the crushed stones that exceed the prescribed range on the first screen from blocking the first screen and affecting the amount of crushed stones entering the discharge bin. The crushed stones on the screen flow onto the movable plate, causing the fourth piston plate inside the regulating chamber to move downward, squeezing the gas inside the regulating chamber into the extrusion chamber, increasing the pressure inside the extrusion chamber, and causing the third piston plate to move with the second connecting piece, which can make the driving piece slide on the rotating shaft, allowing the card piece to enter the card slot, and then rotating the rotating shaft can make the rotating rod and the first synchronous wheel rotate together, so that the whole equipment can move on the track construction road surface, unloading quantitatively while moving, preventing the crushed stone feeding speed from changing, resulting in uneven stone paving.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Embodiment 1

During track construction, gravel is often laid while being transported by a transport vehicle. The amount of gravel unloading cannot be controlled by the moving speed, resulting in uneven gravel unloading and uneven gravel paving, which requires further leveling by manual labor. The labor intensity is high and the efficiency of gravel paving is slow.

Referring to FIG. 1 , FIG. 2 and FIG. 8 , the present invention provides the following technical solution: a discharging device for transporting engineering materials, comprising a mobile frame 1, the mobile frame 1 comprising a mounting frame 11, front wheels 12 and rear wheels 13, characterized in that it also comprises:

The unloading bin 2 is arranged at the top of the mounting frame 11 in an inclined state. The unloading bin 2 is provided with a feed port 21 and a discharge port 22. The height of one end of the unloading bin 2 close to the feed port 21 is higher than the height of the other end of the unloading bin 2 close to the discharge port 22. The purpose of such arrangement is to enable the engineering materials entering the unloading bin 2 to move toward the discharge port 22 by rolling;

The screening mechanism 3 includes a first screen 31 fixedly connected to the inner wall of the discharge bin 2. The first screen 31 is arranged below the feed port 21 and is used for preliminary screening of the engineering materials entering from the feed port 21. A second screen 32 is arranged at one end of the first screen 31 close to the discharge port 22. The second screen 32 is fixedly connected to the inner wall of the discharge bin 2 in an inclined state. The first screen 31 and the second screen 32 are used for screening the crushed stones that exceed the specified range of the crushed stones.

The cleaning mechanism 4 includes a slide 41 arranged on the top of the first screen 31, and the outer wall of the discharge bin 2 is provided with two slide grooves 42, and the two slide grooves 42 are symmetrically arranged. The two ends of the slide 41 slide in the two slide grooves 42 respectively, and the outer wall of the slide 41 is hinged with a cleaning plate 43, and the cleaning plate 43 is used to clean the engineering materials on the first screen 31, so that the engineering materials move to the second screen 32, and the cleaning plate 43 can rotate at a certain angle on the slide 41. The purpose of such a setting is that when the slide 41 drives the cleaning plate 43 to move in the direction close to the second screen 32, the engineering materials on the first screen 31 can be moved to the second screen 32, and when the slide 41 drives the cleaning plate 43 to move in the direction away from the second screen 32, under the influence of the reaction force of the crushed stones of the engineering materials, the cleaning plate 43 rotates on the slide 41, so that the cleaning plate 43 does not carry the crushed stones to move;

The unloading mechanism 5 includes a rotating shaft 51 rotatably connected to the inside of the unloading bin 2, and a plurality of equidistantly distributed unloading members 52 are fixedly connected to the outer circumferential surface of the rotating shaft 51. The rotating unloading members 52 are used to discharge the engineering materials in the unloading bin 2 through the discharge port 22. The number of unloading members 52 should be at least three;

The material discharging mechanism 6 comprises a discharging bin 61 fixedly connected to the bottom of the discharging bin 2, and a rotating rod 62 is rotatably connected to the inner wall of the discharging bin 61 near the discharge port 22, and a spiral auger 63 is arranged on the outer wall of the rotating rod 62. A discharging pipe 64 is fixedly connected to one side of the discharging bin 61, and the spiral auger 63 is used to discharge the engineering materials entering the discharging bin 61 through the discharging pipe 64. The discharging bin 61 can be arranged in an inclined state parallel to the discharging bin 2, and one end of the discharging bin 61 connected to the rotating rod 62 is the lowest end of the inclination. This purpose is to facilitate the engineering materials entering the discharging bin 61 to move to the end of the discharging bin 61 connected to the rotating rod 62, so that the rotating spiral auger 63 drives the engineering materials entering the discharging bin 61 to be discharged through the discharging pipe 64, and the crushed stones discharged through the discharging pipe 64 will fall on the edge of the construction road surface to avoid interference with the crushed stones laid in the middle of the construction road.

A feed bin 9 connected to the lower bin 61 is provided inside the discharge bin 2, and a movable plate 8 is slidably connected to the feed bin 9. The engineering materials on the second screen 32 can enter the lower bin 61 through the feed bin 9. One end of the rotating shaft 51 passing through the discharge bin 2 is fixedly connected to a third synchronous wheel 82, and a first synchronous belt 83 is transmission-connected between the third synchronous wheel 82 and the first synchronous wheel 610;

There are two front wheels 12 and two rear wheels 13, and a drive shaft 14 is fixedly connected between the two rear wheels 13 on the mobile frame 1. A fourth synchronous wheel 15 is fixedly connected to the outer wall of the drive shaft 14, and a second synchronous belt 16 is transmission-connected between the fourth synchronous wheel 15 and the second synchronous wheel 611.

During actual use, the ground of the section to be constructed is first cleaned and flattened, and then the equipment is placed on the track construction road surface where gravel is to be laid. The gravel enters the interior of the unloading bin 2 through the feed port 21 at a constant feeding speed. Since the unloading bin 2 is arranged on the top of the mounting frame 11 in an inclined state, the gravel entering the interior of the unloading bin 2 will roll toward the discharge port 22. At this time, the gravel can be blocked by the discharge piece 52 on the rotating shaft 51 and will not fall directly from the discharge port 22. The multiple discharge pieces 52 are exchanged to block the gravel inside the unloading bin 2 by rotating the rotating shaft 51. At the same time, the crushed stones between two adjacent discharge pieces 52 can be removed during the rotation of the rotating shaft 51. The gravel is pushed out from the discharge port 22, and the discharge amount of the crushed gravel entering the discharge bin 2 is controlled by the clearance capacity of the adjacent discharge parts 52. At the same time, since the first synchronous wheel 610 is connected to the second synchronous wheel 611, when the first synchronous wheel 610 is rotated so that the first synchronous belt 83 drives the third synchronous wheel 82 to rotate, the second synchronous wheel 611 can drive the fourth synchronous wheel 15 to rotate together through the second synchronous belt 16. At this time, the driving shaft 14 drives the two rear wheels 13 to rotate together, so that the whole equipment moves on the track construction road surface, and quantitative unloading is carried out while moving, thereby making the gravel unloading relatively uniform, reducing the uneven phenomenon of gravel paving, and improving the efficiency of gravel paving.

The present invention is provided with the unloading mechanism 5. When laying gravel, the gravel maintains a constant feeding speed. The gravel entering the unloading bin 2 will roll toward the discharge port 22. At this time, the gravel can be blocked by the unloading piece 52 on the rotating shaft 51 and will not fall directly from the discharge port 22. During the rotation of the rotating shaft 51, the gravel between two adjacent unloading pieces 52 is pushed out from the discharge port 22. The unloading amount of the gravel entering the unloading bin 2 is controlled by the accommodation capacity of the gap between the adjacent unloading pieces 52. When the first synchronous wheel 610 is rotated so that the first synchronous belt 83 drives the third synchronous wheel 82 to rotate, the second synchronous wheel 611 can drive the fourth synchronous wheel 15 to rotate together through the second synchronous belt 16. At this time, the driving shaft 14 drives the two rear wheels 13 to rotate together, so that the whole equipment moves on the track construction road surface, and quantitative unloading is performed while moving, thereby making the gravel unloading relatively uniform, reducing the unevenness of gravel paving, and improving the efficiency of gravel paving.

Embodiment 2

However, when laying gravel on the track, the size of the gravel needs to be ensured to be within the specified range. Gravel that is too large will affect the flatness and stability of the railway, while gravel that is too small will affect the bearing capacity of the railway. During use, the above embodiment cannot screen the fed gravel, resulting in a large difference in the size of the gravel laid on the track construction surface. During laying, there is a large difference in the gap between the gravel, which directly affects the gap size between the subsequent train and the rail, reduces the service life of the rail, and affects the quality of construction.

Please refer to Figures 2 to 6. The screening mechanism 3 also includes a third screen 33 disposed below the first screen 31. The end of the third screen 33 away from the discharge port 22 is slidably connected to the inner wall of the discharge bin 2. An adjusting bin 34 is disposed at the bottom of the end of the third screen 33 away from the discharge port 22. A first piston plate 35 is slidably connected to the inside of the adjusting bin 34. A movable part 36 is fixedly connected to the top of the first piston plate 35. The movable part 36 passes through the top of the adjusting bin 34 and is fixedly connected to the bottom of the third screen 33. The movable part 36 is sealingly and slidably connected to the adjusting bin 34. A first elastic part 37 is connected between the bottom of the first piston plate 35 and the inner wall of the adjusting bin 34. The end of the third screen 33 close to the discharge port 22 is rotatably connected to the inner wall of the discharge bin 2. The end of the third screen 33 away from the discharge port 22 is higher than the end of the third screen 33 close to the discharge port 22.

The first screen 31 and the second screen 32 are used to screen the gravel that exceeds the specified range of gravel, and the third screen 33 is used to screen the gravel that is smaller than the specified range of gravel. For example, when laying a high-speed railway, the specified range of gravel is 20-40 mm, then the sieve holes of the first screen 31 and the second screen 32 should be 40 mm, and the sieve holes of the third screen 33 should be less than 20 mm.

It should be noted that when laying gravel, when the engineering material gravel enters the interior of the discharge bin 2 through the feed port 21, the gravel will first pass through the first screen 31 to screen the gravel that exceeds the specified range, so that the gravel that exceeds the specified range is on the first screen 31. At this time, the gravel that passes through the first screen 31 and enters the interior of the discharge bin 2 will contact the third screen 33 and roll on the third screen 33. During the rolling process, the gravel will pass through the third screen 33 to screen the gravel that is smaller than the specified range, so that the gravel that is smaller than the specified range enters the interior of the lower bin 61, and the gravel that meets the specified range will roll toward the discharge port 22 through the inclined third screen 33, move to the movable plate 8, and then be controlled to be discharged through the discharge mechanism 5.

The present invention provides a screening mechanism 3. When gravel enters the discharge bin 2 through the feed port 21, the gravel will first pass through the first screen 31 to screen gravel exceeding a specified range. The gravel that passes through the first screen 31 and enters the discharge bin 2 will contact the third screen 33 and roll on the third screen 33. During the rolling process, the gravel will pass through the third screen 33 to screen gravel smaller than a specified range, thereby ensuring that the laid gravel meets the specified size, avoiding large differences in gaps between the laid gravel, and improving the service life of the rails.

Embodiment 3

Based on the above embodiment, although the gravel can be screened, if the gravel screened out on the first screen is not cleaned in time, it will affect the internal flow of the gravel into the unloading bin, resulting in the unloading mechanism being unable to control the unloading amount of the gravel.

Please refer to Figures 2 to 12. The cleaning mechanism 4 also includes two symmetrically arranged transfer bins 44 fixedly connected to the outer wall of the discharge bin 2.

The outer wall of the lower bin 61 is provided with a driving motor 7, the output end of the driving motor 7 is fixedly connected to the rotating shaft 612, a limiting groove 616 is provided inside the second connecting member 67 close to the driving member 613, the driving member 613 can slide inside the limiting groove 616, a fifth elastic member 68 is connected between the driving member 613 and the first synchronous wheel 610, and the rotating shaft 612 is driven to rotate by the driving motor 7;

The lower bin 61 is fixedly connected with a regulating bin 617, and the regulating bin 617 is slidably connected with a fourth piston plate 618. A fourth elastic member 619 is connected between the bottom of the fourth piston plate 618 and the inner wall of the regulating bin 617. A movable plate 8 is provided inside the discharge bin 2, and the movable plate 8 is arranged between the discharge member 52 and the third screen 33. The end of the movable plate 8 away from the discharge member 52 is rotatably connected to the inner wall of the discharge bin 2, and the end of the movable plate 8 close to the discharge member 52 is slidably connected to the inner wall of the discharge bin 2, and the engineering materials on the third screen 33 will roll onto the movable plate 8 The bottom of one end of the movable plate 8 close to the discharge piece 52 is fixedly connected with a third connecting piece 81, and the movable plate 8 is connected to the fourth piston plate 618 through the third connecting piece 81. The outer wall of the rotating rod 62 is sealed and rotatably connected with a flow sleeve 620. The regulating chamber 617 is connected with the extrusion chamber 65 through the flow sleeve 620. The movable plate 8 can be arranged at an angle, that is, the end of the movable plate 8 away from the discharge piece 52 is high and the end of the movable plate 8 close to the discharge piece 52 is low, so that the gravel can be gathered at the end close to the discharge mechanism 5, which is convenient for the subsequent discharge mechanism 5 to clean the gravel on the movable plate 8.

It should be noted that, in the process of gravel paving, only when the feeding speed of gravel is always consistent, the capacity of the gap between adjacent discharge parts 52 in Example 1 can realize the control of the gravel discharge amount, ensuring that the amount of gravel inside the gap between each adjacent discharge part 52 is consistent. However, since the gravel needs to be screened by the screening mechanism 3, the gravel beyond the specified range stays on the first screen 31 for a long time, which will affect the flow of gravel into the discharge bin 2 through the first screen 31, resulting in inconsistent amounts of gravel inside the gap between adjacent discharge parts 52 each time the rotating shaft 51 is rotated, resulting in unevenness when the gravel is paved, and the paving quality is deteriorated.

In actual use, the crushed stones that pass through the first screen 31 and enter the discharge bin 2 will hit the third screen 33. The third screen 33 is affected by the inertia of the falling stones, so that when the third screen 33 drives the first piston plate 35 to move downward in the regulating bin 34 through the movable member 36, the first elastic member 37 is compressed, and the first piston plate 35 squeezes the gas in the regulating bin 34, so that part of the gas in the regulating bin 34 flows into the two transfer bins 44 through the one-way diverter valve 311 and the second guide pipe 39. Then, the first elastic member 37 is quickly reset, and the third screen 33 drives the first piston plate 35 to move upward inside the regulating chamber 34 through the movable member 36. On the one hand, the external gas is extracted into the regulating chamber 34 through the first guide pipe 38 and the one-way valve 310. On the other hand, the third screen 33 in the reset process contacts and collides with the gravel in the falling process, forming vibration. Therefore, the third screen 33 drives the first piston plate 35 to move back and forth inside the regulating chamber 34 through the continuously falling gravel, so that The gas pressure inside the transfer chamber 44 gradually increases, and the gas pressure pushes the second piston plate 48 to move inside the transfer chamber 44 toward the slide 41, so that the first connecting member 413 pushes the slide 41 to move inside the slide groove 42, so that the cleaning plate 43 cleans the gravel on the first screen 31, and moves the gravel on the first screen 31 to the second screen 32, so as to prevent the gravel on the first screen 31 that exceeds the prescribed range from blocking the first screen 31 and affecting the flow rate of the gravel through the first screen 31. When the piston plate 48 moves inside the transfer chamber 44 toward the sliding member 41, the second elastic member 410 is stretched, and the second piston plate 48 comes into contact with the limiting plate 411, carrying the limiting plate 411 to move inside the transfer chamber 44, squeezing the third elastic member 412. After the second piston plate 48 moves to the extreme position, the air inlet 47 on the sealing plate 46 is connected with the air outlet 45, so that the gas inside the transfer chamber 44 is quickly discharged to the outside, and the third elastic member 412 and the second elastic member 410 are reset.

Further supplemented, the first elastic member 37 is quickly reset, so that the third screen 33 contacts and collides with the gravel in the falling process, forming vibration, which can make the gravel on the third screen 33 flow onto the movable plate 8, and prevent the gravel from piling up on the third screen 33, so that the load capacity on the movable plate 8 is increased, and the fourth piston plate 618 inside the regulating chamber 617 moves downward, and the fourth elastic member 619 is compressed. The fourth piston plate 618 moving downward will squeeze the gas inside the regulating chamber 617 into the extrusion chamber 65 through the transfer sleeve 620, so that the pressure inside the extrusion chamber 65 becomes larger. When the load capacity on the movable plate 8 reaches the limit, the fourth piston plate 618 will move to the limit position, and the pressure inside the extrusion chamber 65 can make the third piston plate 66 carry the second connecting member 67 to move, so that the driving member 613 can slide on the rotating shaft 612, so that the clamping member 61 4 enters the inside of the clamping groove 615, and the rotating shaft 612 enters the inside of the limiting groove 616 and rotates. At this time, the rotating shaft 612 can rotate the rotating rod 62 and the first synchronous wheel 610 together through the driving member 613 and the clamping member 614, thereby driving the second synchronous wheel 611 to rotate. When the first synchronous wheel 610 rotates so that its first synchronous belt 83 drives the third synchronous wheel 82 to rotate, the second synchronous wheel 611 rotates and can drive the fourth synchronous wheel 15 to rotate together through the second synchronous belt 16, so that the whole device moves on the track construction road surface, and quantitatively unloads while moving. The unloading mechanism 5 works when the crushed stones on the movable plate 8 reach a certain weight, and further ensures the unloading amount of the crushed stones each time. The degree to which the load capacity of the movable plate 8 reaches the limit can be adjusted by setting the number of the fourth elastic members 619, that is, the more the number of the fourth elastic members 619, the greater the load capacity of the movable plate 8.

The present invention is provided with the cleaning mechanism 4 and the unloading mechanism 6. The crushed stones that pass through the first screen 31 and enter the inside of the discharge bin 2 will hit the third screen 33. The crushed stones that keep falling make the third screen 33 drive the first piston plate 35 to move back and forth inside the regulating bin 34, so that the air pressure inside the transfer bin 44 is gradually strengthened, so that the second piston plate 48 moves inside the transfer bin 44 toward the direction of the slide 41, so that the crushed stones on the first screen 31 move to the second screen 32 and roll into the inside of the feeding bin 9, so as to prevent the crushed stones on the first screen 31 that exceed the prescribed range from blocking the first screen 31 and affecting the amount of crushed stones entering the inside of the discharge bin 2. The crushed stones on the surface flow onto the movable plate 8, so that the fourth piston plate 618 inside the regulating chamber 617 moves downward, squeezing the gas inside the regulating chamber 617 into the extrusion chamber 65, so that the pressure inside the extrusion chamber 65 increases, so that the third piston plate 66 carries the second connecting member 67 to move, and the driving member 613 can slide on the rotating shaft 612, so that the clamping member 614 enters the clamping groove 615, and then the rotating shaft 612 is rotated to make the rotating rod 62 and the first synchronous wheel 610 rotate together, so that the whole equipment moves on the track construction road surface, and quantitatively unloads while moving, so as to prevent the crushed stone feeding speed from changing and causing unevenness when the stone is paved.
