Description
Technical Field
[0001] This utility model belongs to the technical field of belt conveyors, and in particular relates to a multi-compartment unloading belt conveyor. Background Technology
[0002] Belt conveyors are widely used industrial conveying devices for transporting materials. Their main structure includes a frame, with a head frame and a tail frame installed at both ends of the frame. Belt drums are installed on the head frame and tail frame, and the transmission belt drives the transmission along the belt drums.
[0003] The total length of a belt conveyor can vary greatly depending on the path length of the material being transported, especially for belt conveyors used for long-distance material transport. Therefore, to increase feeding efficiency in actual operation, multiple hoppers for unloading are often installed on the belt conveyor. These hoppers are mounted on a platform, allowing operators to stand on the platform to handle the unloading process.
[0004] During the feeding process, especially when feeding small and lightweight materials, the "reverse impact" between the material and the belt causes a large amount of dust to be generated when the material is fed from the hopper onto the belt conveyor.
[0005] The specific reason is that, in order to ensure the smooth flow of material feeding, the existing technology requires a sufficient height gap between the discharge port of the feeding hopper and the conveyor belt, which increases the upward impact energy of the material falling onto the conveyor belt.
[0006] Therefore, existing technologies prevent dust from escaping by installing a sealed chamber structure of approximately the same length as the belt conveyor on the conveyor frame. However, in actual operation, this type of belt conveyor with a sealed chamber structure is only suitable for short-distance conveying.
[0007] However, for long-distance belt conveyors with a total length, the cost of deploying such sealed chambers is very high and impractical.
[0008] Therefore, in actual operation, how to reduce the serious dust emission during the feeding process of such large-scale, long-distance conveyor belts has become an urgent technical problem that needs to be solved. Utility Model Content
[0009] Based on the above background, the purpose of this utility model is to provide a multi-compartment unloading belt conveyor.
[0010] To achieve the above objectives, the present invention adopts the following technical solution: A multi-compartment unloading belt conveyor includes a belt conveyor body, which includes a conveyor belt for transporting materials, and several unloading bin structures for unloading materials onto the conveyor belt. Each unloading bin structure includes a platform positioned above the conveyor belt, on which unloading bin hopper mechanisms are installed. It also includes a dust cover mechanism that cooperates with the unloading bin hopper mechanisms. The dust cover mechanism includes a cover bracket that covers the conveyor belt, and dust suppression structures are hinged to both ends of the cover bracket. The dust suppression structure includes a dust suppression plate that is hinged and installed. The size of the opening between the dust suppression plate and the baffle bracket is adjusted by a drive structure. The dust suppression plate is positioned above the conveyor belt.
[0011] Preferably, the feeding hopper mechanism includes a feeding hopper; The top of the platform is fixedly installed with a support frame to the material hopper; A guide cylinder is installed at the top center of the platform, the discharge end of the feeding hopper faces the feeding end of the guide cylinder, and the discharge end of the guide cylinder faces the conveyor belt. The discharge end of the guide cylinder is connected to the top position of the baffle bracket.
[0012] Preferably, the top center of the baffle bracket is provided with a feed inlet, and a lower guide cylinder is fixedly connected to the top of the feed inlet. A lower annular flange is integrally formed at the top opening of the lower guide cylinder. The bottom opening of the feed tube is integrally formed with an upper annular flange, and the lower annular flange is fastened to the upper annular flange by bolts.
[0013] Preferably, the longitudinal cross-sectional shape of the baffle bracket is U-shaped; The baffle bracket is fixedly installed on the frame of the belt conveyor body.
[0014] Preferably, a plurality of mounting claw brackets are fixedly installed on the inner side wall of the shield bracket, and the mounting claw brackets are fastened to both sides of the frame by bolts.
[0015] Preferably, the top of the dust suppression plate is detachably fitted with a pair of spaced hinges; The cover bracket has a hinge slot with a hinge tongue.
[0016] Preferably, a push rod is hinged to the lower end of the side wall on both sides of the dust suppression board, and an electric push rod is fixedly installed on the push rod; The electric push rod is hinged and installed at the lower end of the side wall of the baffle bracket.
[0017] Preferably, each of the dust suppression panels is equipped with a dust-blocking curtain structure.
[0018] Preferably, the dust curtain structure includes bearing brackets fixedly installed on both sides of the lower end of the dust suppression plate, and a roller shutter shaft is rotatably connected between the bearing brackets; A dust-proof curtain is wound around the roller shutter shaft.
[0019] Preferably, an escalator is installed on the platform, and the escalator is staggered from the conveyor belt.
[0020] This utility model has the following beneficial effects: 1. By installing a dust cover mechanism at the discharge end of the guide cylinder, the dust cover mechanism covers the conveyor belt (the material discharge point on the belt), thereby suppressing most of the dust and preventing its large-scale diffusion, and pressing the dust down onto the conveyor belt, further reducing the amount of dust escaping.
[0021] 2. During the material feeding process, the material drop point is always covered within the baffle support. The moment the material falls is the key to generating a large amount of dust; the baffle support reduces the amount of dust released into the air during material feeding. Furthermore, after the dust disperses, the dust floating within the baffle support space does not largely follow the conveyor belt, thus providing a relatively enclosed environment for the dust to settle and fall onto the conveyor.
[0022] 3. During operation, the opening range of the dust suppression plates on both sides needs to be increased. Specifically, it needs to be adjusted according to the amount of material on the belt. If the amount of material on the belt is small and the amount of dust is large, the dust suppression plate on the front side can be adjusted to a small-amplitude flipping state by using the electric push rod. When the amount of material and dust is large, the dust suppression plate on the front side can be adjusted by using the electric push rod to get as close to the conveyor belt as possible while maintaining a sufficient safe distance from the material, so as to reduce the amount of dust escaping from the baffle bracket.
[0023] During the dust escape process, guided by the front dust suppression plate, the dust falls towards the material on the conveyor belt. In other words, the dust suppression plate also has the advantage of guiding the dust and causing it to sink back onto the material.
[0024] 4. Because the material hopper structure is arranged in multiple ways along the material conveying direction, dust suppression plates with flip-up sides are designed. The dust suppression plates can be flipped and adjusted to minimize dust dispersion without affecting the smooth material conveying. Attached Figure Description

[0031] Example 1 like Figure 1-6 As shown, a multi-compartment unloading belt conveyor includes a belt conveyor body 1, which is a conventional long-distance conveyor belt disclosed in the prior art. Its main structure includes a frame, with a head frame and a tail frame at both ends. Belt drums for the transmission belt are respectively installed on the head frame and the tail frame, and the belt is driven by a power structure such as a motor or pulley on one side of the belt drum.
[0032] To improve material feeding efficiency, existing technologies employ multiple feeding bin structures arranged along the conveyor belt 12 to increase feeding efficiency.
[0033] Specifically, similar to the existing unloading hopper structure 2, the unloading hopper structure 2 includes a platform 22 positioned above the conveyor belt 12 (in the prior art, to facilitate operators' movement up and down to the platform 22, a ladder is installed on the platform 22, but the ladder is not staggered from the conveyor belt 12 to ensure that it does not interfere with the operation of the conveyor belt 12). Similarly, as in the existing method, the bottom of the platform 22 is supported by a platform bracket 221, and the conveyor belt passes through the gap in the platform bracket 221.
[0034] During the unloading process, the operator can stand on platform 22 to assist in the unloading operation.
[0035] Specifically, it is the same as the existing material hopper structure 2, with a material hopper mechanism installed on the platform 22; specifically, the material hopper mechanism includes a material hopper 21; in the same way as the existing method, the material hopper 21 is fixedly installed on the top of the platform 22 by a bracket 211.
[0036] Meanwhile, in order to ensure that the material can be smoothly fed from the platform 22 to the conveyor belt 12 (the platform 22 is suspended directly above the conveyor belt 12), a guide cylinder 23 is installed at the top center of the platform 22 (specifically, in the same way as the existing method, the platform 22 has a mounting hole, and several mounting seats 231 are fixedly installed on the upper side of the outer wall of the guide cylinder 23, and the mounting seats 231 are fixedly installed on the platform 22 by bolts). The discharge end of the feeding hopper 21 faces the feeding end of the guide cylinder 23, and the discharge end of the guide cylinder 23 faces the conveyor belt 12.
[0037] After the material is fed from the feeding hopper 21 mechanism, it enters the guide cylinder 23 along the discharge end of the feeding hopper 21 mechanism, and is then discharged from the guide cylinder 23 onto the conveyor belt 12.
[0038] Because the discharge end of the guide cylinder 23 needs to maintain a sufficient height distance from the conveyor belt 12 (to avoid the material being discharged too quickly and accumulating at the discharge position of the conveyor belt 12, resulting in material accumulation defects), when the material falls onto the conveyor belt 12, it generates a reverse impact, which in turn causes serious dust dispersion for materials with small particle size and light texture.
[0039] Therefore, in order to reduce dust emission, this utility model, based on the existing structure described above, installs a dust cover mechanism at the discharge end of the guide cylinder 23. The dust cover mechanism covers the conveyor belt 12 (the material discharge point on the belt) to suppress most of the dust and prevent it from spreading in large quantities, and presses the dust down onto the conveyor belt 12, further reducing the amount of dust emission.
[0040] Specifically, the discharge end of the guide cylinder 23 is connected to the top of the baffle bracket 24. The installation method is as follows: the top center of the baffle bracket 24 has a feed port, and the top of the feed port is fixedly connected to the lower guide cylinder 241. The top opening of the lower guide cylinder 241 has an integrally formed lower annular flange; the bottom opening of the guide cylinder 23 has an integrally formed upper annular flange, and the lower annular flange and the upper annular flange are fastened together by bolts.
[0041] Example 2 like Figure 1-6As shown, based on the structure of Embodiment 1, the dust cover mechanism in this embodiment includes a U-shaped cover bracket 24 that covers the conveyor belt 12. The cover bracket 24 is fixedly installed on the frame. Specifically, when the U-shaped cover bracket 24 covers the conveyor belt 12 (including the frame), a sufficient gap is maintained between the cover bracket 24 and the conveyor belt 12. At this time, during the material feeding process, the material drop point is always covered within the cover bracket 24. The moment the material drops is the key to generating a large amount of dust. The cover bracket 24 is used to reduce the large amount of dust that escapes into the air when the material drops. Furthermore, after the dust escapes, the dust floating in the space of the cover bracket 24 will not follow the conveyor belt 12 in large quantities, thus providing a relatively closed environment for the dust to settle and fall onto the conveyor belt.
[0042] This method significantly reduces dust emissions, thus protecting the environment in areas such as workshops.
[0043] The specific installation method is as follows: Several mounting claw brackets A are fixedly installed on the left and right side walls inside the cover bracket 24. According to the existing method, the mounting claw brackets A are fastened to both sides of the frame with bolts.
[0044] Example 3 like Figure 1-6 As shown, this embodiment is based on the structure of embodiment 2. When the material falls onto the conveyor belt 12, the material moves in the transport direction (with...). Figure 3 (The front side is shown), while the dust generated by the material escapes outward from both the front and rear sides of the baffle bracket 24.
[0045] Therefore, in order to further reduce the emission of dust, dust suppression structures 25 are hinged to the front and rear ends of the aforementioned baffle bracket 24.
[0046] The dust suppression structure 25 includes a dust suppression plate 251 that is hinged and installed. The size of the opening between the dust suppression plate 251 and the baffle bracket 24 is adjusted by a drive structure. The dust suppression plate 251 is positioned above the transmission belt 12.
[0047] The dust suppression plate 251 is hinged as follows: a pair of hinge tongues 2511 spaced apart on the top of the dust suppression plate 251 are installed (the hinge tongues 2511 are fastened to the dust suppression plate 251 by bolts); correspondingly, the baffle bracket 24 is provided with a hinge slot for the hinge tongues 2511, and the hinge tongues 2511 are hinged in the hinge slot by means of a pin.
[0048] Meanwhile, in order to flip the dust suppression plate 251, support rods 253 are respectively hinged to the lower ends of the side walls on the left and right sides of the dust suppression plate 251 (the hinge method is: a fixed pin rod protruding outward is fixedly installed on the side wall of the dust suppression plate 251, and the support rod 253 is fixedly connected to a hinge sleeve hinged to the fixed pin rod), and an electric push rod 252 is fixedly installed on the support rod 253.
[0049] Among them, the electric push rod 252 is a conventional electric telescopic rod disclosed in the prior art, and a hinged fixing seat is fixedly connected to the electric push rod 252. The hinged fixing seat is hinged to the baffle bracket 24 by means of a pin (specifically, the electric push rod 252 is hingedly installed at the lower end of the side wall of the baffle bracket 24).
[0050] During operation, the opening range of the dust suppression plates 251 on both sides needs to be increased. Specifically, it needs to be adjusted according to the amount of material on the belt. If the amount of material on the belt is small and the amount of dust is large, the dust suppression plate 251 on the front side is adjusted to a small-amplitude flipping state by the electric push rod 252. When the amount of material and the amount of dust are large, the dust suppression plate 251 on the front side is adjusted by the electric push rod 252 to be as close as possible to the conveyor belt 12 while maintaining a sufficient safe distance from the material, so as to reduce the amount of dust escaping from the baffle bracket 24.
[0051] Meanwhile, during the dust escape process, under the guidance of the front dust suppression plate 251, the dust falls towards the material on the conveyor belt 12. That is, the dust suppression plate 251 also has the advantage of guiding the dust and causing it to sink back onto the material.
[0052] Since the material feeding hopper structure 2 is arranged in multiple ways along the material conveying direction, dust suppression plates 251 with flip-up sides are designed. The dust suppression plates 251 can be flipped and adjusted to minimize dust dispersion without affecting the smooth material conveying.
[0053] In actual operation, the dust suppression board 251 is preferably made of lightweight and rigid materials, such as aluminum alloy or polyurethane.
[0054] Example 4 like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 3, in order to further enhance the dust suppression effect, a dust curtain structure 26 is installed at the lower end of the dust suppression plate 251.
[0055] The dust curtain structure 26 includes bearing brackets 261 fixedly installed on both sides of the lower end of the dust suppression plate 251, and a roller shutter shaft is rotatably connected between the bearing brackets 261; a dust curtain 262 (made of flexible material and wound on the roller shutter shaft) is wound on the roller shutter shaft. Under normal circumstances, the dust curtain 262 will not unroll automatically and needs to be manually pulled down by the operator (with the dust suppression plate 251 in an upward tilted position).
[0056] Among them, the dust curtain 262 is a dust curtain 262 made of a flexible material commonly used in the prior art, such as rubber.
[0057] During operation, the length of the dust curtain 262 is adjusted according to the degree of flipping of the dust suppression board 251. If the degree of flipping of the dust suppression board 251 is large, the length of the dust curtain 262 is increased. The dust curtain 262 is made of flexible material and does not affect the material transmission.
[0058] Furthermore, by bringing the dust curtain 262 close to the material, the amount of material escaping is further reduced.
[0059] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
