Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyor equipment, specifically relating to a bidirectional sand and gravel distribution device. Background Technology

[0002] Large concrete companies have basically achieved intelligent production for processes such as batching, weighing, feeding, and mixing; however, most companies still use manual operation of forklifts for unloading, transporting, and placing sand and gravel raw materials.

[0003] When multiple silos need to be distributed, the existing technology sets a track on the top of the multiple silos, the track spans the multiple silos, and a distribution trolley is set on the track. The distribution trolley is able to slide along the track. A conveyor belt is rotated on the distribution trolley. The conveyor belt can carry sand and gravel materials. Then, as the distribution trolley moves on the track, the sand and gravel materials can be evenly dropped into the silos.

[0004] Adjacent hoppers are separated by retaining walls, and there are several transverse connecting parts on the track. When the material distribution trolley moves longitudinally to distribute the material, the sand and gravel material is prone to fall onto the connecting parts and the top of the retaining walls, which will cause material waste. Utility Model Content

[0005] This utility model provides a two-way sand and gravel distribution device, which aims to reduce the material on connecting parts and the top of the retaining wall.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A bidirectional sand and gravel distribution device is provided, comprising:

[0008] A support truss is located above and spans multiple silos; a track and several transverse connecting components are fixed along the length of the support truss, and each transverse connecting component is arranged along the width of the support truss.

[0009] A fabric trolley is slidably mounted on the track of the supporting truss; a conveyor belt is rotatably mounted on the fabric trolley, and a material drop box is fixedly mounted at both ends of the conveyor belt.

[0010] The material drop box is vertically connected, with the top being the inlet and the bottom being the outlet. A guide ramp is provided between the top of the material drop box and the conveyor belt. The outer wall of the material drop box has a scraper with a first scraping position and a second scraping position in the height direction to accommodate the height of the transverse connecting components and the height of the top of the retaining wall.

[0011] In one possible implementation, each of the discharge boxes is provided with scrapers on both sides, and each discharge box is also connected with an electric push rod corresponding to one scraper. The cylinder of the electric push rod is connected to the discharge box, and the drive end of the electric push rod is connected to the scraper.

[0012] In one possible implementation, a guide rod is connected to the scraper, and the discharge box has a guide component that slides with the guide rod.

[0013] In one possible implementation, the drive end of the electric actuator is connected to a push plate, the push plate having a wedge-shaped groove, and the scraper having a wedge-shaped slider that slides in cooperation with the wedge-shaped groove.

[0014] The scraper and the pusher are provided with a limiting structure, which restricts the sliding of the scraper after the scraper and the pusher slide into place.

[0015] In one possible implementation, the insertion direction of the scraper and the push plate is along the length direction of the push plate or along the width direction of the push plate; the push plate is provided with limiting structures at both ends of the wedge-shaped groove, and each limiting structure includes:

[0016] A limiting frame is connected to the outer wall of the push plate and forms a slide between the limiting frame and the outer wall of the push plate; the limiting frame is located directly above the wedge-shaped slide groove.

[0017] The limiting plate is slidably set within the limiting frame;

[0018] When the scraper and the push plate are inserted and engaged, the bottom of the limiting plate is located above the wedge-shaped groove; after the scraper and the push plate slide into place, the limiting plate slides to the position of the wedge-shaped groove, and the wedge-shaped slider contacts the inner side of the limiting plate.

[0019] In one possible implementation, the top of the limiting plate has a first protrusion that can contact the top of the limiting frame to limit the downward sliding position of the limiting plate; the bottom of the limiting plate has a second protrusion that can contact the bottom of the limiting frame to limit the upward sliding position of the limiting plate.

[0020] In one possible implementation, a telescopic cover is fitted onto the output shaft of the electric actuator, one end of which is connected to the cylinder of the electric actuator, and the other end of which is connected to the push plate.

[0021] In one possible implementation, a telescopic cover is fitted onto the output shaft of the electric actuator, one end of which is connected to the cylinder of the electric actuator, and the other end of which is connected to the drive end of the electric actuator.

[0022] In one possible implementation, the material drop box has an opening at the top position facing the conveyor belt, one side of the guide ramp is connected to the opening position of the material drop box, and the other side of the guide ramp is connected to the support truss.

[0023] The side of the guide ramp connected to the support truss can contact the conveyor belt, so that the material on the conveyor belt falls into the material box along the guide ramp.

[0024] In one possible implementation, the outer wall of the discharge box has a first lifting ring, and the scraper has a second lifting ring;

[0025] The first and second lifting rings are connected by a rope, and the rope is in a slack state when the scraper slides down to its maximum position.

[0026] This utility model provides a bidirectional sand and gravel distribution device. Compared with the prior art, the conveyor belt on the distribution trolley can receive materials, and the rotation of the conveyor belt allows the materials to fall from one end. As the distribution trolley slides on the track, the materials can fall evenly into the hopper, achieving the purpose of uniform distribution. During the distribution process, the scraper can adjust its scraping position according to the height of the transverse connecting parts and the top of the retaining wall to scrape off the materials on the connecting parts and the top of the retaining wall, reducing the amount of material on the connecting parts and the top of the retaining wall, thereby reducing material waste. By setting a drop box and a guide ramp on the distribution trolley, it can be ensured that the materials fall from the drop box. Through the above-mentioned settings of this application, material waste can be reduced. Attached Figure Description

Detailed Implementation

[0035] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] Please refer to the following: Figures 1 to 7 The present invention provides a bidirectional sand and gravel distribution device. The bidirectional sand and gravel distribution device includes a supporting truss 1 and a distribution trolley 2. The supporting truss 1 is located above and spans multiple silos. A track 3 and several transverse connecting components 4 are fixed along the length of the supporting truss 1, each transverse connecting component 4 being arranged along the width of the supporting truss 1. The distribution trolley 2 is slidably mounted on the track 3 of the supporting truss 1. A conveyor belt 5 is rotatably mounted on the distribution trolley 2, and a discharge box 6 is fixed at both ends of the conveyor belt 5. The discharge box 6 is vertically connected, with an inlet at the top and an outlet at the bottom. A guide ramp 7 is provided between the top of the discharge box 6 and the conveyor belt 5. A scraper 61 is provided on the outer wall of the discharge box 6, with a first scraping position and a second scraping position in the height direction to accommodate the height of the transverse connecting components 4 and the height of the top of the retaining wall. The fabric carriage 2 has wheels 21 that rotate with the track 3. The fabric carriage 2 also has a drive motor (not shown in the figure) for driving the wheels 21 to rotate. The fabric carriage 2 is existing technology and will not be described in detail here.

[0037] This utility model provides a bidirectional sand and gravel distribution device. Compared with the prior art, the conveyor belt 5 on the distribution trolley 2 can receive materials, and the material can fall from one end of the conveyor belt 5 by rotating. As the distribution trolley 2 slides on the track 3, the material can fall evenly into the hopper, achieving the purpose of uniform distribution. During the distribution process of the distribution trolley 2, the scraper 61 can adjust the scraping position according to the height of the transverse connecting component 4 and the top of the retaining wall to scrape off the material on the connecting component and the top of the retaining wall, thereby reducing the material on the connecting component and the top of the retaining wall and thus reducing material waste. By setting the drop box 6 and the guide inclined plate 7 on the distribution trolley 2, it can be ensured that the material falls from the drop box 6. Through the above-mentioned settings of this application, material waste can be reduced.

[0038] For example, the support truss 1 has a support member 11, which is connected to the top of the retaining wall. In this embodiment, the height of the transverse connecting member 4 is higher than the height of the top of the retaining wall. The initial scraping position of the scraper 61 is the same as the height of the transverse connecting member 4. Therefore, when scraping the material on the connecting member, there is no need to adjust the position of the scraper 61. When it is necessary to scrape off the material on the top of the retaining wall, the scraper 61 slides down to the height of the top of the retaining wall. Under the drive of the cloth trolley 2, the scraper 61 can scrape off the material on the top of the retaining wall, reducing the material on the top of the retaining wall.

[0039] For example, when there are five hoppers, a feeding mechanism (not shown in the figure) is located in the middle of the five hoppers. The material conveyed by the feeding mechanism can fall onto the conveyor belt 5. The length of the conveyor belt 5 on the fabric trolley 2 is greater than half the length of the five hoppers. Therefore, when the fabric trolley 2 slides to the position of the outermost hopper, the material conveyed by the feeding mechanism can fall to the other end of the conveyor belt 5. Through the rotation of the conveyor belt 5 itself, the material can be transported into the hopper. The feeding mechanism can be a belt conveyor or an auger conveyor.

[0040] For example, the material drop box 6 has an opening 62 at the top position facing the conveyor belt 5. One side of the guide ramp 7 is fixedly connected to the material drop box 6 at the opening 62 and is located at the bottom of the opening 62. The other side of the guide ramp 7 is fixedly connected to the support truss 1. The side of the guide ramp 7 connected to the support truss 1 can contact the conveyor belt 5 so that the material on the conveyor belt 5 falls into the material drop box 6 along the guide ramp 7. With the above arrangement, the guide ramp 7 can guide the material falling from the conveyor belt 5, thereby allowing the material to enter the material drop box 6, and finally fall from the bottom of the material drop box 6 into the hopper below.

[0041] For example, the guide ramp 7 is also connected to side plates 71 on both sides along the width direction of the conveyor belt 5, and the side plates 71 can laterally limit the material. Through the above arrangement, the material on the guide ramp 7 can be laterally limited, reducing the amount of material falling from the side of the guide ramp 7; the height of the support plates 51 on both sides of the conveyor belt 5 is higher than the height of the top of the conveyor belt 5, which can laterally limit the material on the conveyor belt 5; there are several support rollers (not shown in the figure) between the support plates 51 on both sides of the conveyor belt 5, the support rollers are rotatably mounted on the support plates 51, the support rollers are located within the space enclosed by the conveyor belt 5, and the support rollers are in contact with the top position of the conveyor belt 5 to support the top position of the conveyor belt 5. The fabric trolley 2 has a drive motor (not shown in the figure) for driving the conveyor belt 5 to rotate; the specific arrangement of the drive motor is prior art and will not be described further here.

[0042] In some embodiments, such as Figures 1 to 7 As shown, in some embodiments, such as Figure 1 As shown, each material box 6 has a scraper 61 on both sides. The material box 6 is also connected to an electric push rod 8 corresponding to the scraper 61. The cylinder of the electric push rod 8 is connected to the material box 6, and the drive end of the electric push rod 8 is connected to the scraper 61. A guide rod 81 is connected to the scraper 61, and the material box 6 has a guide component 82 that slides with the guide rod 81. A push plate 83 is connected to the drive end of the electric push rod 83. The push plate 83 has a wedge-shaped groove 84, and the scraper 61 has a wedge-shaped slider 611 that slides with the wedge-shaped groove 84. There is a limiting structure 9 between the scraper 61 and the push plate 83. After the scraper 61 and the push plate 83 slide into place, the limiting structure 9 can restrict the sliding of the scraper 61.

[0043] It should be noted that the scraper 61 slides with the push plate 83 through the wedge-shaped slider 611, which can limit the scraper 61 and the push plate 83 in the height direction. After the scraper 61 slides into place, the limiting structure 9 restricts the sliding of the scraper 61 and fixes the scraper 61 on the push plate 83. With the above settings, the positions of the scraper 61 and the push plate 83 can be kept relatively fixed. When the electric push rod 8 drives the scraper 61 to slide up and down, it can restrict the rotation of the scraper 61, thereby making it easier for the scraper 61 to scrape the material of the transverse connecting part 4 and the top of the retaining wall.

[0044] The electric push rod 8 is fixed to the outer wall of the material box 6. The driving end of the electric push rod 8 can drive the scraper 61 to rise and fall, thereby switching the scraper 61 between the first scraping position and the second scraping position to match the height of the transverse connecting component 4 and the top of the retaining wall. The guide component 82 is fixed to the outer wall of the material box 6. The guide component 82 has a through hole for the guide rod 81 to slide. During the process of the electric push rod 8 driving the scraper 61 to slide up and down, the guide rod 81 slides in cooperation with the guide component 82 to make the scraper 61 more stable during the sliding process.

[0045] For example, when the drive end of the electric push rod 8 is connected to the scraper 61 through the push plate 83, the guide rod 81 is fixed on the push plate 83; when the drive end of the electric push rod 8 is directly connected to the scraper 61, the guide rod 81 is fixed on the scraper 61.

[0046] In some embodiments, such as Figures 1 to 7 As shown, the insertion direction of the scraper 61 and the push plate 83 is along the length direction of the push plate 83 or along the width direction of the push plate 83; the push plate 83 is provided with limiting structures 9 at both ends of the wedge-shaped slide groove 84, and each limiting structure 9 includes a limiting frame 91 and a limiting plate 92; the limiting frame 91 is connected to the outer wall of the push plate 83 and forms a slide between the limiting frame 91 and the outer wall of the push plate 83; the limiting frame 91 is located directly above the wedge-shaped slide groove 84; the limiting plate 92 is slidably disposed in the limiting frame 91; wherein, when the scraper 61 and the push plate 83 are inserted and engaged, the bottom of the limiting plate 92 is located above the wedge-shaped slide groove 84; after the scraper 61 and the push plate 83 slide into place, the limiting plate 92 slides to the position of the wedge-shaped slide groove 84, and the wedge-shaped slider 611 contacts the inner side of the limiting plate 92.

[0047] For example, in this embodiment, the scraper 61 slides along the length of the push plate 83. The limiting structure 9 is set on the side wall of the scraper 61 along the length direction. When the scraper 61 slides into the push plate 83, the limiting plate 92 is first slid upward so that the limiting plate 92 is exposed in the wedge-shaped groove 84. Then, the wedge-shaped slider 611 on the scraper 61 slides into the wedge-shaped groove 84. After the wedge-shaped slider 611 slides into place, the entire wedge-shaped slider 611 is located in the wedge-shaped groove 84. At this time, the two ends of the wedge-shaped slider 611 are coplanar with the two sides of the push plate 83. After the limiting plate 92 slides downward, the inner side of the limiting plate 92 can contact the end of the wedge-shaped slider 611. At this time, the two limiting plates 92 can restrict the sliding of the wedge-shaped slider 611, thereby fixing the scraper 61 and the push plate 83 relatively.

[0048] In some embodiments, such as Figures 1 to 7As shown, the top of the limiting plate 92 has a first protrusion 921, which can contact the top of the limiting frame 91 to limit the downward sliding position of the limiting plate 92; the bottom of the limiting plate 92 has a second protrusion 922, which can contact the bottom of the limiting frame 91 to limit the upward sliding position of the limiting plate 92.

[0049] It should be noted that by providing a first protrusion 921 and a second protrusion 922 on the limiting plate 92, the highest and lowest sliding positions of the limiting plate 92 can be limited, thus preventing the limiting plate 92 from sliding out of the limiting frame 91.

[0050] In some embodiments, such as Figures 1 to 7 As shown, a telescopic cover 85 is fitted on the output shaft of the electric push rod 8. One end of the telescopic cover 85 is connected to the cylinder of the electric push rod 8, and the other end of the telescopic cover 85 is connected to the push plate 83.

[0051] It should be noted that when the output shaft of the electric push rod 8 is directly connected to the scraper 61, the other end of the telescopic cover 85 is connected to the output shaft of the electric push rod 8 near the drive end; when the electric push rod 8 is connected to the scraper 61 through the push plate 83, the other end of the telescopic cover 85 is connected to the push plate 83.

[0052] The telescopic cover 85 is fitted onto the output shaft of the electric push rod 8. During the extension and retraction of the output shaft of the electric push rod 8, the telescopic cover 85 can protect the output shaft and reduce the dust adhering to the output shaft of the electric push rod 8.

[0053] In some embodiments, such as Figures 1 to 7 As shown, the outer wall of the material box 6 has a first lifting ring 63 and the scraper 61 has a second lifting ring 64; wherein, the first lifting ring 63 and the second lifting ring 64 are connected by a rope (not shown in the figure), and the rope is in a slack state when the scraper 61 slides down to the maximum position.

[0054] It should be noted that the scraper 61 and the feed box 6 are connected by a rope. During the sliding process of the scraper 61, the rope is always in a slack state, so the rope will not affect the normal lifting and lowering of the scraper 61. In case of an abnormal situation, when the scraper 61 separates from the electric push rod 8, the scraper 61 falls downward under its own weight, and the rope is tightened. Therefore, through the above-mentioned arrangement of this application, when the scraper 61 separates from the electric push rod 8, the rope can provide tension to the scraper 61, preventing the scraper 61 from falling into the feed box.

[0055] For example, the first lifting ring 63 may also be provided on the guide member 82.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
