Description

Technical Field

[0001] This utility model relates to the field of bucket elevator technology, and in particular to a bucket structure and a bucket elevator. Background Technology

[0002] A bucket elevator is a continuous conveying machine that uses a series of buckets fixed on a traction component to transport powdery, granular, and lumpy materials in a vertical direction or at a large angle. It mainly includes a conveying mechanism, a drive mechanism, and buckets.

[0003] When a bucket elevator is in operation, after the buckets are loaded with material, the conveying mechanism drives the buckets to move upward. Because the conveying mechanism is prone to causing the buckets to shake and vibrate during operation, the end of the bucket furthest from the conveying mechanism shakes more during the conveying process, which can easily lead to material spillage. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a bucket structure and a bucket elevator, which provides a blocking effect to prevent material from spilling when the bucket rises.

[0005] According to an embodiment of the present invention, a hopper structure includes a hopper body and a mounting base disposed on one side of the opening of the hopper body. A weight sensing actuation component is provided inside the hopper body. A rotating material blocking component is rotatably connected to the side of the hopper body away from the mounting base. A transmission component connected to the weight sensing actuation component and the rotating material blocking component is provided at the bottom of the hopper body.

[0006] Preferably, the rotating baffle assembly includes rotating rods disposed on both sides of the hopper body and a baffle disposed above the hopper body. One end of the rotating rod is rotatably connected to the hopper body, and the other end is fixedly connected to the baffle. The rotation axes of the rotating rods on both sides are coaxial.

[0007] More preferably, the baffle is an arc-shaped panel, and its axis is coaxial with the rotation axis of the rotating rod.

[0008] More preferably, the weight sensing motion assembly includes a sensing groove disposed at the bottom of the bucket body, a sensing plate movably disposed in the sensing groove, a piston chamber disposed below the sensing groove, and a first piston rod disposed in the piston chamber. The sensing plate is connected to the bottom of the sensing groove through an elastic element. A second piston rod extending into the piston chamber is fixedly connected to the bottom of the sensing plate. The first piston rod extends to the outside and is connected to the transmission assembly.

[0009] More preferably, the piston chamber includes a first chamber disposed perpendicular to the sensing plate, a second chamber communicating with and perpendicular to the first chamber, a second piston rod disposed in the first chamber, and a first piston rod disposed in the second chamber.

[0010] More preferably, the transmission assembly includes a sliding rod slidably disposed on the side of the bucket body, and two transmission rods respectively rotatably connected to both ends of the sliding rod, the two transmission rods being rotatably connected to the first piston rod and the rotating baffle assembly respectively.

[0011] In a further preferred embodiment, the side of the bucket body is provided with a guide groove, and the sliding rod is disposed in the guide groove.

[0012] According to an embodiment of the present invention, a bucket elevator includes the aforementioned bucket structure.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] A weight-sensing actuator is installed at the bottom of the bucket body, and a rotatable baffle is installed on the side of the bucket body away from the transmission mechanism. The baffle and the weight-sensing actuator are connected by a transmission component. When the bucket body is full of material, the weight-sensing actuator is activated, which drives the baffle to the blocking position through the transmission component. After the bucket body is unloaded, the weight-sensing actuator and the baffle are reset. This can prevent material from spilling when lifting material, and will not block the bucket body from loading material after unloading. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] This utility model provides an embodiment, such as Figure 1As shown, a hopper structure includes a hopper body 1 and a mounting base 2 disposed on one side of the opening of the hopper body 1. The mounting base 2 is used for detachable connection with a transmission mechanism. A weight sensing actuation component 3 is provided inside the hopper body 1. A rotating material blocking component 4 is rotatably connected to the side of the hopper body 1 away from the mounting base 2. A transmission component 5 connected to the weight sensing actuation component 3 and the rotating material blocking component 4 is provided at the bottom of the hopper body 1.

[0020] When the bucket 1 is filled with material, the weight of the material causes the weight sensing component 3 to activate. The weight sensing component 3 drives the rotating baffle component 4 to rotate to the top of the bucket 1 away from the mounting base 2 via the transmission component 5. During the upward movement of the bucket 1, when the bucket 1 vibrates and shakes, it can prevent the material from spilling from this side.

[0021] Specifically, the rotating baffle assembly 4 includes rotating rods 401 disposed on both sides of the bucket body 1 and baffles 402 disposed above the bucket body 1. In this embodiment, there are two rotating rods 401 on each side. One end of the rotating rod 401 is rotatably connected to the bucket body 1, and the other end is fixedly connected to the baffles 402. The rotation axes of the rotating rods 401 on both sides are coaxial.

[0022] In order to facilitate the rotation of the baffle 402 close to the side of the bucket body 1 away from the mounting seat 2, in a further embodiment, the baffle 402 is an arc panel, and its axis is coaxial with the rotation axis of the rotating rod 401. During the rotation of the baffle 402, it is always close to the side of the bucket body 1 away from the mounting seat 2, which can prevent materials from falling between the baffle 402 and the bucket body 1.

[0023] like Figure 1 , Figure 2 As shown, specifically, the weight sensing motion assembly 3 includes a sensing groove 301 disposed at the bottom of the bucket body 1, a sensing plate 302 movably disposed in the sensing groove 301, a piston chamber 303 disposed below the sensing groove 301, and a first piston rod 304 disposed in the piston chamber 303. The sensing plate 302 is clearance-fitted with the sensing groove 301 with zero clearance. The sensing plate 302 is connected to the bottom of the sensing groove 301 through an elastic member 308. In this embodiment, the elastic member 308 is a spring. A second piston rod 305 extending into the piston chamber 303 is fixedly connected to the bottom of the sensing plate 302. The first piston rod 304 extends to the outside and is connected to the transmission assembly 5.

[0024] When the material is loaded into the bucket 1, the gravity of the material causes the induction plate 302 to move downward against the force of the elastic element 308. The second piston rod 305 drives the first piston rod 304 to move in the piston chamber 303. The first piston rod 304 drives the rotating material stop assembly 4 to rotate through the transmission assembly 5.

[0025] After the bucket 1 unloads the material, the sensing plate 302 is reset under the action of the elastic element 308, and drives the second piston rod 305 to reset. The second piston rod 305 drives the rotating material blocking assembly 4 to reset through the first piston rod 304 and the transmission assembly 5.

[0026] Specifically, the piston chamber 303 includes a first chamber 306 disposed perpendicular to the sensing plate 302, a second chamber 307 communicating with and perpendicular to the first chamber 306, a second piston rod 305 disposed in the first chamber 306, and a first piston rod 304 disposed in the second chamber 307.

[0027] Specifically, the transmission assembly 5 includes a sliding rod 501 slidably disposed on the side of the bucket body 1, and two transmission rods 502 respectively rotatably connected to both ends of the sliding rod 501. The two transmission rods 502 are respectively rotatably connected to the first piston rod 304 and the rotating baffle assembly 4.

[0028] In order to limit the movement path of the sliding rod 501, in a further embodiment, the side of the bucket body 1 is provided with a guide groove 101, and the sliding rod 501 is disposed in the guide groove 101.
