Description

Technical Field

[0001] The invention relates to the technical field of discharging equipment, in particular to automatic discharging equipment with a quantitative discharging buffer function. Background Art

[0002] The hopper is the main equipment in the unloading process. There are two types of hoppers: mobile hoppers and fixed hoppers. Fixed hoppers are used in port terminals and have a fixed unloading point. Due to the fixed installation point, the hopper cannot be moved. It is usually used in conjunction with a fixed grab ship unloader or self-unloading ship to feed trucks or conveyors. The whole machine runs smoothly and can ensure efficient loading and unloading of materials.

[0003] The prior art, such as (CN216583741U, discloses a sand material hoisting bucket for construction), proposes that when unloading is required after hoisting, the device is directly placed on the unloading platform, and the device is continuously lowered after the bottom plate contacts the ground. The weight of the hopper and the sand and gravel inside presses the bottom box in, and when the bottom box continues to enter the interior of the hopper, the first discharge chute and the second discharge chute are continuously connected, so that the sand and gravel in the hopper are discharged outward from the first discharge chute and the second discharge chute, thereby completing automatic unloading after hoisting, so that during the unloading process, the material is directly discharged from the discharge chute, and no relevant buffer mechanism is set to reduce the material output speed, and it is impossible to avoid the material from impacting the place where the material is stored at a relatively fast speed, so that the dust in the place is blown away by the impact of the material. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic discharging device with a quantitative discharging buffer function to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An automatic discharging device with a quantitative discharging buffer function comprises a support frame and a hopper, wherein the hopper is placed above the support frame, a discharging port is provided at the bottom of the hopper, a gate is provided in the discharging port, and the opening of the discharging port is controlled by the gate, a buffer assembly is provided on the side of the discharging port away from the hopper, and a pressure sensor is provided in the hopper;

[0007] The weight of the material in the hopper is detected by a pressure sensor, and the weight of the material discharged through the discharge port is analyzed, thereby achieving the effect of quantitative discharge.

[0008] Preferably, the buffer assembly includes a transition pipe, the transition pipe is connected to the discharge port, a deformation pipe is provided on the side of the transition pipe away from the discharge port, and an output pipe is provided on the side of the deformation pipe away from the transition pipe.

[0009] The staff opens the gate in the discharge port, and the material in the hopper is immediately transported to the transition pipe through the discharge port. The material is transported to the deformation pipe through the transition pipe. The material is blocked in the deformation pipe, and then the flow speed of the material slows down when flowing through the deformation pipe, thereby achieving buffering treatment of the material during the discharge process, avoiding the material from being directly transported from the discharge port to the truck bucket, thereby causing impact on the truck bucket, and avoiding the dust brought out by the material when impacting the truck bucket to form dust, which causes the support frame to be covered with dust.

[0010] Preferably, the deformable tube consists of an inner tube and an outer tube, a bracket is provided at the bottom of the inner tube, and the bracket passes through the outer tube and is connected to the output tube.

[0011] After the material enters the deformable tube, it is transported through the space between the inner tube and the outer tube. After flowing to the bottom of the outer tube, the material is transported to the output tube through the flow channel between the two adjacent brackets. Since the outer tube is arranged in a certain arc shape, when the material is transported from the outer tube to the output tube, multiple flows of material will be formed, flowing from the edge of the output tube to the center of the output tube, so that several flows of material converge in the center, that is, the material flows directly impact each other, thereby slowing down the flow speed of the material in the output tube, and further improving the buffering effect of the material when discharging.

[0012] Preferably, the inner tube is composed of a plurality of inner tube segments, and the outer tube is composed of a plurality of outer tube segments, wherein the plurality of inner tube segments are arranged around the axis of the inner tube, and the plurality of outer tube segments are arranged around the axis of the outer tube.

[0013] Preferably, the inner tube sheet and the outer tube sheet are both made of flexible rubber, and the inner tube sheet and the outer tube sheet are provided with folds.

[0014] Both the inner and outer segments are made of flexible rubber, so that when the output pipe and the transition pipe squeeze the outer segment, and when the impact block and the bottom plate squeeze the inner segment, the inner and outer segments can be effectively deformed, thereby adjusting the distance between the inner and outer pipes, thereby changing the flow space of the material and realizing a change in the flow speed of the material. By arranging folds on the inner and outer segments, when the inner and outer segments are squeezed and bent, no gaps will appear between two adjacent inner segments or two adjacent outer segments, thereby preventing material from flowing out from between two adjacent inner segments or two adjacent outer segments.

[0015] Preferably, an impact block is provided on the side of the inner tube away from the output tube, a plurality of springs are provided at the bottom of the impact block, a bottom plate is provided at the bottom of the springs, the side of the bottom plate is connected to the inner tube, and the bottom of the bottom plate is connected to the bracket.

[0016] The material is transported from the discharge port to the transition pipe. During the transportation process, the material impacts the impact block, so that when the impact block is impacted and squeezed by the material, the impact block moves to the side away from the transition pipe, causing the impact block to squeeze the spring, causing the spring to be squeezed and contracted. At this time, the impact block also drives the inner tube to move and deform, so that the distance between the upper and lower ends of the inner tube becomes shorter, and the distance between the outermost end point of the inner tube segment and the outer tube segment becomes shorter, thereby shortening the distance between the inner tube and the outer tube, that is, the space for material movement becomes smaller, so that when the material flows through the space between the inner tube and the outer tube, the flow rate of the material is reduced, thereby achieving the effect of material discharge buffering, avoiding the vertical transportation of the material into the truck bucket, causing the dispersion of dust.

[0017] Preferably, an extension plate is provided on the outer wall of the output tube, a plurality of worm gears are provided on the extension plate, a screw rod is provided inside the worm gear, a motor is provided on the side of the screw rod away from the extension plate, the drive shaft of the motor is connected to the screw rod, and the screw rod is slidably connected to the extension plate through the worm gear.

[0018] The controller controls the motor to start. When the motor rotates, it drives the screw to rotate. When the screw rotates, it fits with the worm gear, so that the worm gear drives the extension plate to move along the axis of the screw. When the material conveying speed is fast, the extension plate drives the output pipe to move toward the side close to the discharge port. When the output pipe moves, it drives the outer tube to move, so that the distance between the upper and lower ends of the outer tube becomes shorter, so that the outer tube segment is squeezed and deformed. The shortest distance between the outermost end point of the outer tube segment and the axis of the outer tube becomes longer, so that the outer tube segment forms a larger bend. When the material is conveyed, it needs to move a longer distance, thereby alleviating the speed of the material during falling conveying.

[0019] When the material conveying speed is slow, the extension plate drives the output pipe to move to the side away from the discharge port. When the output pipe moves, it drives the outer pipe to move, so that the distance between the upper and lower ends of the outer pipe becomes longer, thereby stretching and deforming the outer pipe segment. The shortest distance between the outermost end point of the outer pipe segment and the axis of the outer pipe becomes smaller, so that the outer pipe segment forms a smaller bend (approximately a straight line). When conveying materials, it needs to move a shorter distance, thereby increasing the speed of the material during falling conveying.

[0020] Preferably, a vibration bar is provided at the bottom of the screw rod, and a vibration generator is also provided at the bottom of the screw rod.

[0021] The vibration bar is extended into the truck bucket, and the vibration generator is started to transmit the vibration to the truck bucket through the vibration bar. After the material in the hopper is transported to the truck bucket, it is affected by the vibration and spread out in the truck bucket, which reduces the gap between the materials and avoids the materials from piling up into pointed piles in the truck bucket.

[0022] Preferably, a maintenance platform is provided in the middle of the support frame.

[0023] By setting up a maintenance platform, staff can inspect and repair the hopper and buffer device on the maintenance platform.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. When the output pipe and transition pipe squeeze the outer pipe segment, and when the impact block and bottom plate squeeze the inner pipe segment, the inner and outer pipe segments can be effectively deformed, thereby adjusting the distance between the inner and outer pipes, thereby changing the flow space of the material and realizing the change of the material flow rate. By providing folds on the inner and outer pipe segments, when the inner and outer pipe segments are squeezed and bent, no gap will appear between two adjacent inner pipe segments or two adjacent outer pipe segments, thereby preventing the material from flowing out from between two adjacent inner pipe segments or two adjacent outer pipe segments.

[0026] 2. Since the outer tube is arranged in a certain arc shape, when the material is transported from the outer tube to the output tube, multiple flows of material will be formed, flowing from the edge of the output tube to the center of the output tube, so that several flows of material converge in the center, that is, the material flows directly impact each other, thereby slowing down the flow speed of the material in the output tube, and further improving the buffering effect of the material when discharging.

[0046] As a specific embodiment of the present invention, a vibration bar 40 is provided at the bottom of the screw rod 39 , and a vibration generator is also provided at the bottom of the screw rod 39 .

[0047] Working principle of the present invention:

[0048] The staff opens the gate in the discharge port 21, and the material in the hopper 2 is immediately transported to the transition pipe 31 through the discharge port 21. The material is then transported to the deformation pipe 32 through the transition pipe 31. The material is blocked in the deformation pipe 32, and the flow speed of the material is slowed down when flowing through the deformation pipe 32, thereby achieving buffering of the material during the discharge process, avoiding the material being directly transported from the discharge port 21 to the truck bucket, thereby causing impact on the truck bucket, and avoiding the dust brought out by the material when impacting the truck bucket to form dust, thereby causing the support frame 1 to be covered with dust;

[0049] The material is transported from the discharge port 21 to the transition pipe 31. During the transport process, the material impacts the impact block 36. When the impact and compression of the material are applied, the impact block 36 moves away from the transition pipe 31, causing the impact block 36 to squeeze the spring 37, causing the spring 37 to be squeezed and contracted. At this time, the impact block 36 also drives the inner tube 34 to move and deform, shortening the distance between the upper and lower ends of the inner tube 34. The distance between the outermost end of the inner tube segment 341 and the outer tube segment 351 is shortened, thereby shortening the distance between the inner tube 34 and the outer tube 35. That is, the space available for the material to move is reduced, thereby reducing the flow rate of the material when it flows through the space between the inner tube 34 and the outer tube 35.

[0050] After the material flows to the bottom of the outer tube 35, it is transported to the output tube 33 through the flow channel between two adjacent brackets. Since the outer tube 35 is arranged in a certain arc shape, when the material is transported from the outer tube 35 to the output tube 33, multiple flows of material are formed, flowing from the edge of the output tube 33 to the center of the output tube 33. The multiple flows of material converge at the center, that is, the material flows directly impact each other, thereby slowing down the flow speed of the material in the output tube 33.

[0051] The inner and outer segments 341, 351 are both made of flexible rubber. This allows them to effectively deform when the output pipe 33 and the transition pipe 31 squeeze the outer segments 351, and when the impact block 36 and the bottom plate 38 squeeze the inner segments 341, 351. This adjusts the distance between the inner tube 34 and the outer tube 35, thereby changing the flow space for material and altering the flow rate of material. By providing folds on the inner and outer segments 341, 351, when the inner and outer segments 341, 351 are squeezed and bent, no gaps are formed between adjacent inner segments 341 or adjacent outer segments 351, thereby preventing material from flowing out from between adjacent inner segments 341 or adjacent outer segments 351.

[0052] The controller controls the motor to start. When the motor rotates, it drives the screw rod 39 to rotate. When the screw rod 39 rotates, it engages with the worm gear, so that the worm gear drives the extension plate 331 to move along the axis of the screw rod 39. When the material conveying speed is fast, the extension plate 331 drives the output pipe 33 to move toward the side close to the discharge port 21. When the output pipe 33 moves, it drives the outer tube 35 to move, so that the distance between the upper and lower ends of the outer tube 35 becomes shorter, thereby causing the outer tube segment 351 to be squeezed and deformed. The shortest distance between the outermost end point of the outer tube segment 351 and the axis of the outer tube 35 becomes longer, so that the outer tube segment 351 forms a larger bend, and needs to move a longer distance when conveying the material, thereby reducing the speed of the material during falling conveying.

[0053] When the material conveying speed is slow, the extension plate 331 drives the output tube 33 to move away from the discharge port 21. When the output tube 33 moves, it drives the outer tube 35 to move, so that the distance between the upper and lower ends of the outer tube 35 becomes longer, thereby stretching and deforming the outer tube segment 351. The shortest distance between the outermost end point of the outer tube segment 351 and the axis of the outer tube 35 becomes smaller, so that the outer tube segment 351 forms a smaller bend (approximately a straight line). When conveying materials, it needs to move a shorter distance, thereby increasing the speed of the material during falling conveying.

[0054] The vibration bar 40 is extended into the truck bucket, and the vibration generator is started so that the vibration is transmitted to the truck bucket through the vibration bar 40. After the material in the hopper 2 is transported to the truck bucket, it is affected by the vibration and spread out in the truck bucket, so that the gap between the materials is reduced, thereby avoiding the materials from piling up into a pointed pile in the truck bucket.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
