Abstract
Description
Technical Field
[0001] This utility model belongs to the field of material transportation technology, and in particular relates to a material hopper device for preventing material deviation during discharge. Background Technology
[0002] In industrial production, the transportation of bulk materials is a crucial component of the production process, especially in fields such as building materials, chemical raw materials, and grains. Bucket conveyors, as a common transportation tool, are widely used in various material handling machinery such as belt conveyors, bucket elevators, and chain bucket conveyors. Their performance directly affects production efficiency and material safety.
[0003] To prevent material deviation during transportation, existing hopper devices typically employ a centrally symmetrical design and incorporate anti-deviation structures such as baffles and guide plates inside the hopper. Two anti-deviation structures are generally installed, one on each side of the hopper's interior. These two structures are angled, forming a guide space that gradually narrows from top to bottom. After falling into this guide space, the material descends through the bottom outlet to the center of the hopper's bottom. While these anti-deviation devices can reduce material deviation to some extent, the following technical problems still exist in practical applications:
[0004] 1. Complex Structure: Existing anti-deviation structures in hopper devices require support structures for fixation. Some anti-deviation structures use hinged installation to increase adjustment functionality and are equipped with springs or other devices to adjust their tilt angle. This complex structure increases manufacturing costs and makes installation and maintenance cumbersome, further increasing operating costs. 2. Short Service Life: In actual use, complex anti-deviation devices are prone to damage due to long-term impact and wear from materials, affecting their service life and reliability. 3. Material Retention: When the hopper device discharges material, the anti-deviation structure can easily become an obstruction, causing material to remain inside the hopper. Utility Model Content

[0031] The chain bucket conveyor includes a frame, chain, sprockets, motor, and buckets. The chain and sprockets form a chain drive mechanism, which is symmetrically installed on both sides of the frame. Each chain drive mechanism has two sprockets, one at each end of the frame, with the chain installed between them. Buckets are installed between the two chain drive mechanisms, with adjacent chains connected to both sides of each bucket. Multiple buckets are continuously arranged along the chain distribution direction. The motor drives two sprockets at one end of the frame to rotate, causing each sprocket to drive the buckets via two chains, thus transporting material from one end of the frame to the other. Material is fed from top to bottom into the buckets at one end of the frame. As the buckets move to the other end of the frame and rotate downwards with the chain, the material is emptied from the buckets for unloading. The buckets in the chain bucket conveyor are the conveying bucket device of this application.
[0032] like Figures 1 to 4 As shown in an illustrative embodiment of the present invention, the material feeding anti-deviation transport hopper device includes a hopper body 1 and a guide plate 2.
[0033] The hopper body 1 consists of multiple side plates 101 and a bottom plate 102, which together form the hopper body 1. The top of the hopper body 1 has an opening for material feeding and discharging. A guide plate 2 is installed inside the hopper body 1.
[0034] The hopper body 1 is installed to the chain bucket conveyor and moves in the direction of the center line thereof. The side plates 101 are located at the front, rear, left and right sides of the moving direction of the hopper body 1. The guide plates 2 are two in number and are symmetrically arranged along the center line of the hopper body 1, so that the two guide plates 2 are respectively located at the left and right sides of the internal space of the hopper body 1. The bottom end of the guide plate 2 is connected to the bottom plate 102 of the hopper body 1, and the top end, front side edge and rear side edge of the guide plate 2 are all connected to the adjacent side plate 101, so as to close the left and right corners at the bottom of the internal space of the hopper body 1. The two guide plates 2 are both arranged to be inclined relative to the bottom plate 102, so that the space between the two guide plates 2 is gradually expanded from bottom to top.
[0035] The material is poured into the hopper body 1 through the opening of the hopper body 1, and a part of the material directly falls to the center of the bottom plate 102 for stacking, and another part of the material falls to the guide plate 2. The material falling on the guide plate 2 slides downward along the guide plate 2, so that the material on the left and right sides in the hopper body 1 is all guided by the guide plate 2 to the center of the bottom plate 102 for stacking. Under the guidance of the two guide plates 2, the material falling into the hopper body 1 is concentrated in the center of the internal space thereof, so as to avoid the material from being deviated to one side in the internal space of the hopper body 1.
[0036] By arranging the inclined guide plates 2 at the left and right sides of the internal space of the hopper body 1, the material is guided to the center of the internal space of the hopper, so as to realize the deviation prevention of the center of gravity of the material in the hopper, and the structure is simple and the manufacturing cost is low.
[0037] The edges of the guide plate 2 are all connected to the hopper body 1, so that the installation stability of the guide plate 2 is higher, the ability to resist the impact of the material is stronger, and the reliability of the guide plate 2 is improved; secondly, the full edge connection of the guide plate 2 makes the falling material not enter the lower side of the guide plate 2, so as to avoid the blockage of the guide plate 2 to the unloading of the material when the hopper body 1 is overturned to unload the material, so that the material can be completely unloaded; in addition, the full edge connection of the guide plate 2 makes the space of the bottom corners at the two sides in the internal space of the hopper body 1 be closed, that is, two closed spaces are formed in the internal space of the hopper body 1, the closed spaces are filled with gas, so that two air spring structures are formed at the bottom corners of the two sides of the hopper body 1, which buffer the impact of the material falling on the guide plate 2, and further reduce the noise.
[0038] The guide plate 2 supports and reinforces the hopper body 1 inside, improves the structural strength of the hopper body 1 itself, and reduces the impact of the material on the side plates 101 and the bottom plate 102 of the hopper body 1 under the blockage of the guide plate 2, thereby improving the reliability of the hopper body 1.
[0039] In some embodiments, the top ends of the guide plates 2 are connected to the top ends of the adjacent side plates 101, so that the guide plates 2 extend upward to the opening of the hopper body 1. If the top ends of the guide plates 2 do not extend to the opening of the hopper body 1, when the height of the material accumulated in the hopper body 1 is flush with the top ends of the guide plates 2, the guide plates 2 will lose the guiding effect on the subsequent falling material, and the material at the top of the hopper body 1 will be offset to the center. The structure design that the top ends of the guide plates 2 are connected to the top ends of the side plates 101 ensures that in the direction perpendicular to the center line of the hopper body 1, the material falling to the guide plates 2 is guided to the center or falls to the center of the bottom plate 102 of the hopper body 1, ensuring that all the material in the hopper body 1 can be guided to the center, and the center of gravity of the material will not be offset to one side, improving the stability of the hopper body 1 moving on the conveyor.
[0040] In some embodiments, the hopper body 1 moves along the direction of its center line, and the side plates 101 include a first side plate 1011 and a second side plate 1012, which are arranged in sequence along the moving direction of the hopper body 1; the first side plate 1011 and the second side plate 1012 are both arranged obliquely to gradually narrow the space between them from top to bottom. This structure design makes the space inside the hopper body 1 gradually narrow from top to bottom in two directions perpendicular to each other, ensuring that the material can be guided to the center of the bottom plate 102 in both directions, and the material will not be offset to one side in both directions, improving the stability of the hopper body 1 moving on the conveyor.
[0041] In some embodiments, the first side plate 1011 and the second side plate 1012 are both inclined toward the moving direction of the hopper body 1, so that the bottom of the hopper body 1 is offset to the direction opposite to the moving direction. Due to the arrangement of the guide plates 2, the volume of the material that can be accommodated inside the hopper body 1 is reduced, so that the stacking height of the material in the hopper body 1 increases under the condition that the amount of material remains unchanged, and the material is more likely to fall out of the hopper body 1 under the action of vibration. This structure design makes the material have more tendency to move in the direction of sliding down along the second side plate 1012 during the movement of the hopper body 1 due to its inertia, ensuring that the material efficiently and more slides to the bottom of the hopper body 1, and avoiding the material falling out due to the vibration of the hopper body 1 during the movement.
[0042] In some embodiments, the angle between the first side plate 1011 and the plane of the bottom plate 102 is smaller than the angle between the second side plate 1012 and the plane of the bottom plate 102. This design allows the second side plate 1012 to be flipped to the horizontal position earlier when the hopper body 1 is moved to the end of the conveyor and flipped down, so that the material can be poured out earlier, avoiding the situation that the hopper body 1 is still at the end of the conveyor and has moved a distance to the other end when the material is completely discharged, improving the efficiency of discharging the material and reducing the size of the opening of the structure for carrying or conveying the discharged material. In addition, this design also allows the first side plate 1011 to cover more of the material from top to bottom, which can prevent the material from falling out of the hopper body 1 during movement.
[0043] In some embodiments, the top end of the first side plate 1011 is lower than the top plate of the second side plate 1012, so that the top end of the first side plate 1011 and the adjacent two side plates 101 form a connecting groove 105. This design reduces the space occupation on one side of the top of the hopper body 1, facilitating the connection of the adjacent hopper body 1, and preventing interference between adjacent hopper bodies 1 during operation on the conveyor.
[0044] In some embodiments, the top end of the second side plate 1012 is integrally connected with a connecting plate 104 extending away from the first side plate 1011, so that the connecting plate 104 extends into the connecting groove 105. This design allows the connecting plate 104 to cover the gap between adjacent hopper bodies 1, preventing the material from falling through the gap to the bottom of the conveyor, ensuring that the material can enter the hopper body 1 for transportation, and reducing the loss of material during transportation.
[0045] In some embodiments, the bottom of the first side plate 1011 is provided with a first plate body portion 103 bent towards the second side plate 1012. This design reduces the space occupation on one side of the bottom of the hopper body 1, preventing interference between adjacent hopper bodies 1 when the hopper body 1 is flipped down. In addition, this design allows the bottom of the guide plate 2 to have more edges, allowing the guide plate 2 to be connected to the side plate 101 of the hopper body 1 at multiple angles, improving the stability of the structure.
[0046] In some embodiments, the transport hopper device further comprises a driving connecting seat 3 connected to the chain of the conveyor. The driving connecting seat 3 has two driving connecting seats 3 symmetrically arranged along the center line of the hopper body 1 and fixed on the outer side surface of the adjacent side plate 101. The driving connecting seat 3 drives the chain to move to drive the hopper body 1 to move back and forth between the two chain wheels of the conveyor, and continuously convey the material. In addition, the driving connecting seat 3 is connected to the side plate 101, so that the driving connecting seat 3 corresponds to the enclosed space inside the hopper body 1 with the guide plate 2. When the chain is running, the vibration transmitted to the hopper body 1 can be absorbed to a certain extent by the enclosed space, reducing the vibration transmitted to the material and improving the stability during the material conveying process.
[0047] In some embodiments, the driving connecting seat 3 is an angle iron parallel to the bottom plate 102. This structure design makes the driving connecting seat 3 low in manufacturing cost and has high structural strength itself. When installed on the side plate 101, it can serve as a reinforcing rib to improve the strength of the side of the hopper body 1. In addition, the angle iron can provide a horizontal plate body that can be installed on the chain from top to bottom, so that the chain can fully bear the weight of the hopper body 1 through the driving connecting seat 3, improving the stability during movement.
[0048] The two ends of the driving connecting seat 3 extend to the edge of the corresponding side of the side plate 101, so as to ensure that the driving connecting seat 3 is fully covered on the side plate 101, further improving the strength of the side of the hopper body 1.
[0049] Finally, it should be noted that: the embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts of each embodiment can be referred to.
