Description

Technical Field

[0001] This utility model relates to a hopper, and more particularly to a bucket elevator anti-spillage hopper. Background Technology

[0002] The buckets of a bucket elevator are typically connected to a chain via a shaft and are evenly distributed on the elevator's traction components (such as the chain). The buckets are generally open-topped, with sides and bottom made of welded or integrally formed sheet metal. Their bottoms are usually U-shaped or V-shaped. During elevator operation, the buckets receive material from the feed hopper, move upwards with the traction components, and then tip over to unload at the top. Existing buckets often have simple right-angle or flat inlets, causing material to continuously spill to the sides during transport due to inertia or vibration. This spillage is particularly noticeable at high speeds or under conditions of uneven particle size. After long-term operation, a large amount of material accumulates at the bottom of the channel, increasing material loss and subsequent cleaning costs. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the objective is to provide a bucket elevator bucket that prevents material spillage.

[0004] The technical solution of this utility model is: a bucket elevator anti-spillage bucket, including a bucket body, mounting base, frame, trapezoidal block, discharge channel, guide block, lip plate and side baffle. Two mounting bases are provided on the rear side of the bucket body, and the two mounting bases are arranged symmetrically from left to right. The bucket body is installed on the transmission chain of the elevator through the mounting bases. The inside of the bucket body is provided with a material cavity. The lower space of the material cavity is in the shape of an inverted trapezoid with a larger upper part and a smaller lower part. The upper left and right sides of the material cavity of the bucket body are symmetrically provided with frames. The frames are provided with a vertically penetrating discharge channel. Guide blocks are provided on the opposite side of the two frames and on the front side of the bucket body. Side baffles are provided on the top of the bucket body. Lip plate is provided on the upper front side of the bucket body.

[0005] Furthermore, the guide block has a triangular cross-section and faces the center of the material cavity. The three guide blocks form a cone-shaped feed inlet in the upper part of the hopper body, which is used to gather the material to the center of the material cavity.

[0006] Furthermore, it also includes trapezoidal blocks. Trapezoidal blocks are provided in the rear part of the frame. The short sides of the trapezoidal blocks all face forward. The trapezoidal blocks make the discharge channel form a channel structure in which the material outlets on the upper and lower sides gradually narrow towards the middle.

[0007] Furthermore, it also includes a hammer and a pad. The trapezoidal block has a hollow internal structure, with a hammer rotating on its front side. Pads are provided on the upper and lower sides of the rear part of the trapezoidal block, and the pads are located at the point where the hammer strikes.

[0008] Furthermore, it also includes baffles, with baffles symmetrically arranged on the lower front side of the hopper.

[0009] Furthermore, both the lip plate and the side baffles are made of flexible materials.

[0010] The beneficial effects are: 1. Through the cooperation of the frame and the guide block, this utility model can gather the material in the center of the hopper body during the feeding process, reducing the material from falling to both sides of the hopper. At the same time, the discharge channel in the frame can buffer the material that falls to both sides, allowing the material to flow back into the hopper, effectively reducing the spillage phenomenon during the feeding stage.

[0011] The guide block of this invention can guide the material to flow smoothly outward along its inclined surface when the main body is flipped for unloading. At the same time, the hammer inside the trapezoidal block can be used to strike the hopper to assist, reducing the accumulation of residual material in the hopper body and improving the thoroughness and stability of unloading.

[0016] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] A type of bucket elevator anti-spillage bucket, such as Figure 1-3 As shown, the hopper includes a hopper body 1, mounting base 2, frame 3, trapezoidal block 4, discharge channel 410, guide block 5, lip plate 6, and side baffle 7. Two mounting bases 2 are symmetrically arranged on the rear side of the hopper body 1. The mounting bases 2 can stably install the hopper body 1 on the transmission chain of the elevator, ensuring the stability of the hopper during the lifting process. The lower part of the material cavity inside the hopper body 1 is in the shape of an inverted trapezoid, which helps the material to slide naturally to the lower part under the action of gravity. Frames 3 are symmetrically arranged on the left and right sides of the upper part of the material cavity of the hopper body 1. The frame 3 has a vertically penetrating discharge channel 410. When feeding, the material enters the hopper from the top. The upper front side of the hopper body 1 and the opposite side of the two frame 3 are provided with guide blocks 5 with triangular cross sections facing the center of the material cavity. The three guide blocks 5 form a cone-shaped feed inlet in the upper part of the hopper body 1.

[0018] When material enters, guide block 5 gathers it to the center of the hopper, resulting in a more concentrated material distribution. Since material entering the hopper experiences impact and tends to spread, guide block 5 restrains it, reducing splashing. As material gradually fills the hopper from the area surrounded by guide block 5, it flows primarily downwards under gravity, rather than rapidly accumulating to the sides. Due to the material's fluidity and downward flow characteristic under gravity, some material may squeeze into discharge channel 410 when it falls to the sides. Although discharge channel 410 is connected to the hopper, when material accumulates in large quantities within the hopper, it prioritizes filling the lower space rather than rapidly filling discharge channel 410. An empty cavity remains above the discharge channel, providing a buffer for subsequent material lifting and conveying, preventing excessive accumulation of material on the upper sides of the hopper during feeding.

[0019] like Figure 1-3 As shown, trapezoidal blocks 4 are provided in the rear part of the inner side of the frame 3. The short sides of the trapezoidal blocks 4 all face forward. The trapezoidal blocks 4 make the discharge channel 410 form a channel structure in which the upper and lower material inlets gradually narrow towards the middle. This structure further constrains and guides the material entering the discharge channel 410 as it flows downward, preventing the material from flowing randomly in the discharge channel 410, thereby enhancing the buffering and guiding effect on the material.

[0020] like Figure 3 As shown, the trapezoidal block 4 has a hollow internal structure, with a rotating hammer 8 on its front inner side. Pads 9 are located on the upper and lower sides of the rear inner part of the trapezoidal block 4, with each pad 9 positioned at the impact point of the hammer 8. When the hopper flips or vibrates / shakes during the operation of the elevator, the hammer 8 rotates or shakes and strikes the pad 9, generating a knocking vibration. This vibration helps the material adhering to or accumulating in the discharge channel 410 to fall smoothly during the feeding stage, preventing blockage and ensuring the discharge channel 410 remains unobstructed, thus better fulfilling its buffering and guiding functions for the material.

[0021] like Figure 1 and Figure 2 As shown, symmetrical baffles 10 are provided on the lower front side of the hopper. In the old-style bucket elevator, when unloading, the material is discharged from one hopper onto the outer shell of the next hopper. Since there is no chute on the outside of the shell, the material is easily spilled from the left and right sides to the bottom of the box, reducing the unloading efficiency. This anti-spillage hopper forms a chute at the lower front of the hopper through the baffles 10. When the hopper is tilted and the material is guided, the baffles 10 can effectively guide the material falling onto the next hopper body 1, causing the material to be discharged towards the receiving part, preventing the material from scattering to the sides and improving the unloading efficiency.

[0022] Both the lip plate 6 and the side baffle 7 are made of flexible materials. During the operation of the elevator, when the bucket collides with other components or materials, the flexible lip plate 6 and side baffle 7 can act as a buffer, reducing material splashing and bucket damage caused by rigid collisions, and also reducing noise to some extent. Moreover, the flexible material can better fit the edge of the bucket, enhancing the material containment effect and further preventing material from spilling out from the edge of the bucket.

[0023] Throughout the feeding process, as the elevator conveyor chain operates, the hopper body 1 moves with the chain to the loading position. The material falls from above and enters the cone-shaped feed inlet formed by three guide blocks 5. Under the converging effect of the guide blocks 5, the material is guided to the center of the material cavity, reducing diffusion to both sides. Some of the material that falls to both sides enters the discharge channel 410 inside the frame 3. At the same time, the lip plate 6 and the side baffle 7 effectively prevent material from spilling out from the top and sides, improving the integrity of the feeding process.

[0024] During the feeding stage, after the hopper body 1 passes the drive sprocket, it begins to rotate with the feed inlet facing downwards. At this point, the hopper body 1 on this section of the transmission chain has moved to the unloading position. The hopper body 1 gradually rotates to 180 degrees, and this process is relatively short. The material in the feed chamber begins to be discharged under the influence of inertia and gravity. At this time, the lower inclined structure of the guide block 5 provides a smooth sliding path for the material, accelerating the discharge of the material. Due to the angle change and inertia of the hopper body 1 during rotation, the hammer 8 inside the trapezoidal block 4 swings and strikes the pad block 9 near the lower rear part of the trapezoidal block 4 due to gravity and inertia. The swinging impact will generate a momentary vibration inside the trapezoidal block 4. This vibration is transmitted to the hopper body 1 through the trapezoidal block 4, causing the material remaining in the channel to fall and be discharged along with the main material. The baffle plate 10 on the lower front side of the hopper body 1 forms a chute. When the material is unloaded, the baffle plates 10 on the left and right sides can laterally constrain the discharged material, causing the material to spread to the left and right sides and guide it to flow to the designated unloading area. This prevents some material in the upper hopper body 1 from falling directly onto the lower hopper body 1 and continuing to be transported with the hopper body. After the hopper body 1 flips again, it falls into the lower part of the elevator, causing the material to accumulate.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
