Description

Technical Field

[0001] The invention relates to the technical field of material conveying, and in particular to a material conveying device. Background Art

[0002] In the process of producing and processing bulk materials, automatic feeding equipment is usually used to continuously convey bulk materials. The Chinese patent with the announcement number CN212862875U discloses a washboard type silo mechanism, which includes a cabinet, a storage inclined slide bucket, an electric control cabinet, a washboard lower step, a washboard middle step, a washboard upper step, a transmission active sprocket, a material distribution mechanism cylinder, a transmission driven sprocket, a wheel seat, a transmission motor, a transmission chain, an abnormal material removal slideway and a washboard step lifting cylinder.

[0003] When the above technical scheme is in use, scattered materials are poured directly into the inclined sliding bucket of the material storage, and the materials slide along the inclined sliding bucket to the lower step of the washboard, and the washboard step lifting cylinder drives the lower step of the washboard to rise, and lifts the materials to the middle step of the washboard, and the washboard step lifting cylinder drives the middle step of the washboard to rise, and lifts the materials to the upper step of the washboard, and the materials slide onto the conveying chain by their own gravity, and are transferred by the conveying motor to drive the conveying chain to convey each material to the cylinder position of the material distribution mechanism. During the conveying process, materials that are not in the correct position will slide to the abnormal material removal chute, and finally flow into the original inclined sliding bucket of the material storage.

[0004] Since the position of the abnormal material removal chute is fixed, the unqualified materials will accumulate on the storage sloping bucket along the abnormal material removal chute, causing the accumulated materials to be unable to be lifted and transported in time, and the position without accumulated materials is idle, and the washboard part corresponding to the idle position cannot be fully utilized, resulting in the problem of slow conveying efficiency. Moreover, the accumulated materials are easy to slide directly onto the push plate in the form of stacking. During the conveying process of the push plate and the conveying chain, the stacked materials are likely to fall back into the storage sloping bucket, affecting the conveying efficiency.

[0005] Therefore, the art needs a material conveying device to solve the above problems. Summary of the invention

[0006] The present invention provides a material conveying device, aiming to solve the problems in the related art that the material distribution on the storage hopper of the conveying equipment is uneven, resulting in the push plate not being fully utilized, and the material is easily stacked and loaded, affecting the conveying efficiency.

[0007] A material conveying device of the present invention includes a machine body, a push-plate loading mechanism, a conveying mechanism and a screening mechanism, wherein the conveying direction of the conveying mechanism is defined as the right, the machine body is slidably connected to a material holding plate along the left and right directions, and a driving member is provided on the machine body to drive the material holding plate to move left and right, the material holding plate is tilted downward from a side away from the push-plate loading mechanism to a side close to the push-plate loading mechanism, and the screening mechanism includes a pushing block and a material guiding ramp corresponding to the position of the pushing block, the pushing block is fixedly connected to the machine body and is located above the conveying mechanism, the material guiding ramp is fixedly connected to the machine body and extends to above the material holding plate, a limited height plate is provided on the machine body, and a loading space for block materials to pass through is formed between the bottom of the height limiting plate and the top of the material holding plate.

[0008] The present invention drives the material holding plate to move left and right through a driving member, so that the material holding plate swings left and right to the accumulated block materials, spreads out the accumulated block materials, and spreads the block materials more evenly on the material holding plate, which is conducive to the block materials sliding smoothly onto the push plate loading mechanism, thereby improving the loading efficiency; by setting a height limiting plate, when the block materials slide from the material holding plate to the push plate loading mechanism, the block materials stacked on top will be intercepted by the height limiting plate, and only a single layer of block materials are allowed to pass through the loading space, thereby reducing invalid loading and improving the loading efficiency; and the height limiting plate can directly intercept block materials whose placement state does not meet the requirements, thereby increasing the proportion of block materials that meet the requirements that are pushed onto the conveyor belt, and reducing the probability of invalid loading.

[0009] Preferably, a second driving member is provided on the machine body, and the second driving member drives the height limiting plate to move in a direction perpendicular to the upper surface of the material containing plate.

[0010] By adjusting the distance between the bottom of the height limiting plate and the top of the material holding plate, the height of the loading space can be adjusted to accommodate the feeding of block materials of different specifications, thereby improving the applicability of the present invention.

[0011] Preferably, a driving member three is provided on the machine body, and the driving member three drives the height limiting plate to move towards or away from the push plate feeding mechanism, and the movement direction of the height limiting plate is parallel to the upper surface of the material holding plate.

[0012] The height limiting plate is driven by the driving component to continuously push the block materials that cannot pass through the loading space, so that the block materials stacked on top and the block materials that do not meet the placement requirements are continuously moved on the material holding plate, which is conducive to changing the current position of the block materials on the material holding plate, so that more block materials that meet the requirements can quickly slide to the loading space.

[0013] Preferably, the second driving member includes an electric push rod 2 and a mounting rod, the electric push rod 2 is fixedly connected to the machine body, the mounting rod is connected to the driving end of the electric push rod 2, and the mounting rod slides with the machine body in a direction perpendicular to the upper surface of the material holding plate, and the driving member 3 and the height limiting plate are installed on the mounting rod.

When the mounting rod moves to the left, the guide groove pushes the guide column to drive the height limiting plate to move in the direction away from the push plate feeding mechanism; when the mounting rod moves to the right, the guide groove pushes the guide column to drive the height limiting plate to move in the direction close to the push plate feeding mechanism.

[0015] Preferably, the driving member four includes telescopic rods symmetrically arranged at the left and right ends of the mounting rod, one end of the telescopic rod is rotatably connected to the mounting rod, and the other end is rotatably connected to the material holding plate, and when the driving member one drives the material holding plate to move left and right, the material holding plate drives the mounting rod to move synchronously through the telescopic rod.

[0016] Preferably, a groove extending in the left-right direction is provided on the upper surface of the material holding plate, and a spring 1 is connected between the side of the height limiting plate facing the pushing plate material feeding mechanism and the mounting rod, and a accommodating cavity is provided in the height limiting plate, the guide column is slidably matched with the accommodating cavity, and the top of the guide column is elastically connected to the accommodating cavity through a spring 2, the accommodating cavity is filled with hydraulic oil, and a hydraulic pump is provided on the height limiting plate, and the hydraulic pump is connected to the accommodating cavity, when the spring 2 is in a natural state, part of the structure of the guide column is located in the guide groove, and when the guide column is located at the right end of the guide groove, the spring 1 is in a natural state.

[0017] When the guide post is located at the left end of the guide groove, spring 1 is in a compressed state. By controlling the hydraulic pump to suck the hydraulic oil in the accommodating chamber, the guide post is separated from the guide groove. Spring 1 pushes the height limit plate to move away from the pushing plate feeding mechanism, so that the height limit plate forms a large thrust on the block material in front of it. The block material that does not meet the placement requirements may be turned over due to the jamming of the groove during the process of being pushed vigorously by the height limit plate, thereby becoming a state that meets the placement requirements. The block material stacked on top may fall directly on the material holding plate after being pushed vigorously by the height limit plate, waiting to slide towards the upward material space.

[0021] By providing the pushing mechanism, the discharging direction of the material on the conveyor belt is changed, so that the placement of the material conveying device of the present invention is more flexible.

[0022] The beneficial effects of the present invention are as follows: the present invention drives the material holding plate to move left and right through the driving member 1, so that the material holding plate shakes the accumulated block materials left and right, spreads the accumulated block materials, and spreads the block materials more evenly on the material holding plate, which is conducive to the smooth sliding of the block materials onto the push plate loading mechanism, thereby improving the loading efficiency; By setting a height limit plate, when the block materials slide from the material holding plate to the push plate feeding mechanism, the block materials stacked on top will be intercepted by the height limit plate, allowing only a single layer of block materials to pass through the feeding space, reducing ineffective feeding and improving feeding efficiency; Moreover, the height limit plate can directly intercept block materials that do not meet the requirements, thereby increasing the proportion of block materials that meet the requirements pushed onto the conveyor belt and reducing the probability of invalid loading.

DETAILED DESCRIPTION

[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] like Figures 1 to 6 As shown, a material conveying device of the present invention includes a body 1, a push plate loading mechanism, a conveying mechanism and a screening mechanism. The conveying direction of the conveying mechanism is defined as the right direction. The conveying mechanism includes a conveyor belt 2 and a motor 21. The body 1 is rotatably connected to a plurality of rotating rollers (not shown in the figure) evenly spaced along the left and right directions. The conveyor belt 2 is arranged around the outer periphery of the rotating roller. The motor 21 is fixedly connected to the body 1, and the output end of the motor 21 is fixedly connected to one of the rotating rollers. The motor 21 drives the rotating roller to rotate, and the rotating roller drives the conveyor belt 2 to rotate, so that the conveyor belt 2 conveys materials.

[0032] The push plate material feeding mechanism includes a fixed plate 3, a push plate 31 and an electric push rod 32. The fixed plate 3 is fixedly connected to the machine body 1 and is evenly spaced in the front-rear direction. The push plates 31 and the fixed plates 3 are alternately arranged and fit with the fixed plates 3. The push plates 31 and the fixed plates 3 are tilted from bottom to top toward the direction close to the conveying mechanism. The electric push rod 32 is fixedly connected to the machine body 1. The bottom of the push plate 31 is connected through a connecting plate 33. The connecting plate 33 is fixedly connected to the driving end of the electric push rod 32. The electric push rod 32 drives the connecting plate 33 to drive all the push plates 31 to move up and down synchronously along the fixed plate 3 to achieve step-by-step lifting of materials.

[0033] The machine body 1 is connected to a material receiving plate 4 in a sliding manner along the left-right direction. The material receiving plate 4 is tilted downward from a side away from the push plate feeding mechanism to a side close to the push plate feeding mechanism. The machine body 1 is provided with a driving member 1 for driving the material receiving plate 4 to move left and right. As an example, the driving member 1 is an electric push rod 1 41, which is fixedly installed in the machine body 1, and the material receiving plate 4 is fixedly connected to the driving end of the electric push rod 1 41.

[0034] The screening mechanism includes a push block 5 and a material guide ramp 51 corresponding to the position of the push block 5. The push block 5 is fixedly connected to the machine body 1 and is located above the conveyor belt 2. The material guide ramp 51 is fixedly connected to the machine body 1 and extends to above the material holding plate 4. The machine body 1 is also fixedly connected to an arc-shaped guide plate 52 located in front of the conveyor belt 2. The arc-shaped guide plate 52 is located on the right side of the push block 5.

[0035] The block material placed on the material receiving plate 4 will slide toward the pushing plate loading mechanism. When the pushing plate 31 moves upward, the pushing plate 31 close to the material receiving plate 4 pushes the block material upward, so that the bottom of the block material is slightly higher than or flush with the top of the adjacent fixed plate 3 on the rear side. Since the pushing plate 31 and the fixed plate 3 are inclined, the block material will automatically slide to the top of the adjacent fixed plate 3 on the rear side, and then the pushing plate 31 moves downward. When the top of the middle pushing plate 31 is lower than the top of the adjacent fixed plate 3 on the front side or flush with the top of the adjacent fixed plate 3 on the front side, the block material will slide to the top of the middle pushing plate 31, and then the pushing plate 31 moves upward. The middle push plate 31 pushes the block material so that the bottom of the block material is slightly higher than or flush with the top of the fixed plate 3 adjacent to the rear side, and the block material automatically slides to the top of the fixed plate 3 adjacent to the rear side, and then the push plate 31 moves downward. When the top of the last push plate 31 is lower than the top of the fixed plate 3 adjacent to the front side or flush with the top of the fixed plate 3 adjacent to the front side, the block material will slide to the top of the last push plate 31, and then the push plate 31 moves upward. The last push plate 31 pushes the block material so that the bottom of the block material is slightly higher than the top of the machine body 1, and the block material automatically slides onto the conveyor belt 2 and moves with the conveyor belt 2.

[0036] Since the minimum spacing between the pushing block 5 and the guide ramp 51 is fixed, when the conveyor belt 2 transports the block materials to the pushing block 5, the pushing block 5 will organize the block materials and make the block materials move in the direction close to the guide ramp 51. If the state of the block materials falling on the conveyor belt 2 does not meet the requirements, when passing between the pushing block 5 and the guide ramp 51, it will fall to the guide ramp 51 due to its own imbalance, and return to the material holding plate 4 along the guide ramp 51 to wait for reloading. The block materials that meet the requirements will pass through the pushing block 5 smoothly and continue to move with the conveyor belt 2. When the block materials contact the arc guide plate 52, they will move to the preset position on the conveyor belt 2 under the guidance of the arc guide plate 52.

[0037] When more and more block materials that do not meet the requirements fall from the material guide ramp 51 onto the material receiving plate 4, they will be piled up on the material receiving plate 4. The driving member drives the material receiving plate 4 to move left and right, so that the material receiving plate 4 shakes the piled block materials left and right, spreads the piled block materials, and spreads the block materials more evenly on the material receiving plate 4, which is conducive to the smooth sliding of the block materials onto the push plate loading mechanism, thereby improving the loading efficiency.

[0038] Since block materials may be stacked together and slide onto the push plate loading mechanism, and be pushed onto the conveyor belt 2 in a stacked state, when passing through the pushing block 5, the stacked block materials may all fall on the material guide ramp 51, resulting in invalid loading and affecting the loading efficiency. Therefore, in this embodiment, a height limiting plate 6 is provided on the machine body 1, and a loading space for block materials to pass through is formed between the bottom of the height limiting plate 6 and the top of the material holding plate 4. When the block materials slide from the material holding plate 4 to the push plate loading mechanism, the block materials stacked above will be intercepted by the height limiting plate 6, and only a single layer of block materials are allowed to pass through the loading space, thereby improving the loading efficiency.

[0039] The machine body 1 is provided with a second driving member, which drives the height limiting plate 6 to move in a direction perpendicular to the upper surface of the material holding plate 4. The second driving member includes a second electric push rod 7 and a mounting rod 71, the mounting rod 71 is slidably matched with the machine body 1 in a direction perpendicular to the upper surface of the material holding plate 4, the second electric push rod 7 is fixedly connected to the machine body 1, and the mounting rod 71 is connected to the driving end of the second electric push rod 7. The second electric push rod 7 drives the mounting rod 71 to move, and the mounting rod 71 drives the height limiting plate 6 to move, thereby adjusting the distance between the bottom of the height limiting plate 6 and the top of the material holding plate 4, that is, adjusting the height of the feeding space to adapt to the feeding of block materials of different specifications, thereby improving the applicability of the present invention.

[0040] In addition, by adjusting the height of the loading space, the block materials whose placement state does not meet the requirements can be directly intercepted on the front side of the height limiting plate 6. For example, when the block material is a rectangular thin plate, the state that meets the placement requirements is that the height of the block material is the minimum side length. When the block material is in other placement states, it will be intercepted by the limiting plate, thereby increasing the proportion of block materials that meet the requirements that are pushed onto the conveyor belt 2 and reducing the probability of invalid loading.

[0041] The machine body 1 is provided with a driving member 3, which drives the height limiting plate 6 to move toward or away from the push plate feeding mechanism, and the movement direction of the height limiting plate 6 is parallel to the upper surface of the material holding plate 4. Figures 2 to 5As shown, the driving member 3 includes a guide groove 72 opened on the mounting rod 71 and a guide column 61 fixedly connected to the height limiting plate 6, and the guide groove 72 is inclined from left to right in a direction away from the push plate feeding mechanism. The two ends of the height limiting plate 6 are respectively fitted with the inner wall of the machine body 1, and the mounting rod 71 is slidably connected to the driving end of the electric push rod 2 7 along the left and right directions, and the mounting rod 71 is connected to the driving member 4 that drives it to move along the left and right directions.

[0042] When the mounting rod 71 moves to the left, the guide groove 72 pushes the guide column 61 to drive the height limiting plate 6 to move in the direction away from the pushing plate loading mechanism. When the mounting rod 71 moves to the right, the guide groove 72 pushes the guide column 61 to drive the height limiting plate 6 to move in the direction close to the pushing plate loading mechanism, thereby realizing that the height limiting plate 6 continuously pushes the block materials that cannot pass through the loading space, so that the block materials stacked above and the block materials that do not meet the placement requirements continuously move on the holding plate 4, which is conducive to changing the current position of the block materials on the holding plate 4, so that more block materials that meet the requirements can quickly slide to the loading space.

[0043] like Figure 3 As shown, the driving member 4 includes telescopic rods 8 symmetrically arranged at the left and right ends of the mounting rod 71, and the telescopic rod 8 includes an intermediate rod and sleeve rods slidably connected to the two ends of the intermediate rod. One sleeve rod of the telescopic rod 8 is rotatably connected to the mounting rod 71, and the other sleeve rod is rotatably connected to the material receiving plate 4. When the driving member 1 drives the material receiving plate 4 to move left and right, the material receiving plate 4 drives the mounting rod 71 to move synchronously through the telescopic rod 8.

[0044] The upper surface of the material holding plate 4 is provided with grooves 42 extending in the left-right direction, and the grooves 42 are evenly spaced along the inclined direction of the material holding plate 4. Figures 4 to 6 As shown, a spring 1 62 is connected between the side of the height limiting plate 6 facing the plate pushing material feeding mechanism and the mounting rod 71, and a receiving chamber 63 is provided in the height limiting plate 6. The guide column 61 is slidably matched with the receiving chamber 63, and the top of the guide column 61 is elastically connected with the receiving chamber 63 through a spring 2 64. The receiving chamber 63 is filled with hydraulic oil, and a hydraulic pump 65 is provided on the height limiting plate 6, and the hydraulic pump 65 is connected with the receiving chamber 63. When the spring 2 64 is in a natural state, part of the structure of the guide column 61 is located in the guide groove 72, and when the guide column 61 is located at the right end of the guide groove 72, the spring 1 62 is in a natural state. A notch is provided on the mounting rod 71 to avoid the hydraulic pump 65.

[0045] When the guide post 61 is located at the left end of the guide groove 72, the spring 1 62 is in a compressed state. By controlling the hydraulic pump 65 to suck the hydraulic oil in the accommodating chamber 63, the guide post 61 moves upward relative to the guide groove 72. When the guide post 61 is separated from the guide groove 72, the spring 1 62 pushes the height limiting plate 6 to move in a direction away from the pushing plate feeding mechanism, so that the height limiting plate 6 exerts a greater thrust on the block material in front of it. The block material that does not meet the placement requirements may be turned over due to the jamming of the groove 42 during the process of being pushed vigorously by the height limiting plate 6, thereby becoming a state that meets the placement requirements. The block material stacked on top may fall directly on the material holding plate 4 after being pushed vigorously by the height limiting plate 6, waiting to slide towards the upward material space.

[0046] When the mounting rod 71 moves to the left to a position where the guide column 61 is opposite to the right end of the guide groove 72, the hydraulic pump 65 is controlled to inject hydraulic oil into the accommodating chamber 63, and the guide column 61 moves downward relative to the accommodating chamber 63 and enters the guide groove 72 to re-match with the guide groove 72.

[0047] See again Figure 1 The machine body 1 is provided with a discharge port 11 and a pushing mechanism, which includes an electric push rod 49 and a movable plate 91. The electric push rod 49 is fixedly connected to the machine body 1, and the movable plate 91 is fixedly connected to the driving end of the electric push rod 49. The movable plate 91 is opposite to the discharge port 11, and the electric push rod 49 drives the movable plate 91 to move in the front-back direction. The movable plate 91 pushes the qualified block materials on the conveyor belt 2 to the discharge port 11 to complete the feeding.

[0048] It is understandable that in other embodiments, the pusher mechanism can be omitted, and the discharge port can be directly opened at the right end of the conveyor belt. After the block material on the conveyor belt moves to the discharge port with the conveyor belt, the block material will be separated from the conveyor belt under the action of inertia and thrown out from the discharge port, thereby completing the feeding. Those skilled in the art can choose whether to set the pusher mechanism according to the placement position of the material conveying device of the present invention, actual usage, etc.
