Description

Technical Field

[0001] This utility model is a novel trough tilt angle adjustment device for a seated feeder, mainly used in the technical field of material transfer in heavy-duty seated feeders in various industries such as metallurgy, mining, and coal. Background Technology

[0002] Currently, with the widespread use of vibrating feeders in my country's metallurgical, mining, and coal industries, the trough inclination angle is generally fixed after the feeder is installed and put into use. It is well known that changing the trough inclination angle is a way to adjust the feeding rate. When materials are stored in the open air, the material may be dry and easy to flow due to weather conditions, so the feeding rate will increase. During the rainy season, the material will have a high moisture content and become sticky and easy to stick together, so the feeding rate will decrease and fail to meet the requirements, thus reducing production efficiency. In particular, it is necessary to adjust the trough inclination angle of a pedestal feeder at any time, but it is very difficult to operate in actual application, which is a major problem for enterprises. Summary of the Invention

[0003] To overcome the difficulties in adjusting the inclination angle of the trough of the aforementioned vibrating feeder, the purpose of this utility model is to provide a novel trough inclination angle adjustment device for a pedestal feeder that can adjust the inclination angle of the feeder trough at any time according to changes in the looseness and viscosity of the material, thereby ensuring the feeding amount.

[0004] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows: a novel seat-type feeder trough tilt angle adjustment device, comprising a displacement adjustment device, a lifting device, a fixed seat, an active slide, an electro-hydraulic actuator, a gear set, and a passive slide, characterized in that: a vibration damping spring at the front opening of the feeder trough sits on the displacement adjustment device 1; the displacement adjustment device 1 contains rollers 1.1; a lifting device 2 is located below the displacement adjustment device 1; a support seat 2.1 is installed in the middle of the lifting device 2; rollers 2.2 are installed at the lower part of the support seat 2.1; and a fixed seat... 3. Inside the lifting device 2, the upper part is a drive slide 4 installed on one side of the fixed seat 3. The lower part of the drive slide 4 is provided with an upper rack 4.1. The lower part of the upper rack 4.1 is connected to the gear set 6. The lower part of the gear set 6 is connected to the lower rack 7.1 installed on the lower part of the passive slide 7 on the other side of the fixed seat 3. The roller 2.2 is on the upper part of the drive slide 4 and the passive slide 7. The lower part of the passive slide 7 is connected to the fixed seat 3. The electro-hydraulic push rod 5 is installed on the outside of the fixed seat 3 through the push rod support 5.1. The front end of the electro-hydraulic push rod 5 passes through one side of the fixed seat 3 and is connected to the drive slide 4.

[0005] Compared with the prior art, the present invention has the following characteristics when using the above-described structure.

[0006] 1. The innovation of this utility model compared with the prior art is that it uses an electro-hydraulic actuator to push the active slide. The rack under the active slide rotates through a gear set and moves in the opposite direction simultaneously with the rack under the passive slide, which in turn drives the passive slide. The roller moves up and down in the angle between the upper inclined surfaces of the active and passive slides. The angle between the upper inclined surfaces of the active and passive slides changes the height position of the roller through the opening stroke of the electro-hydraulic actuator. The roller is self-locked by the angle between the two inclined surfaces, achieving a highly efficient stepless adjustment of the height of the lifting device. This is a major innovation in adjusting the tilt angle of the feeder trough. It can operate at any time according to the changes in the looseness and viscosity of the material. It is easy to operate and effectively solves the problem that when the material is dry and easy to flow, the feed amount becomes too large and exceeds the requirements. When the material contains a lot of moisture, it becomes sticky and easy to stick, and the feed amount becomes too small and fails to meet the requirements, thus reducing production efficiency.

[0007] 2. The unique structural design of this utility model, with its electro-hydraulic actuator horizontally installed externally, reduces the load it bears, makes it easy to achieve self-locking, is less prone to damage and has a longer service life, is convenient to install and replace, and is safer, which can greatly reduce costs and improve production efficiency.

[0008] 3. The novel and unique structural design of this utility model adopts an external electro-hydraulic actuator to drive the internal mechanical transmission mechanism. The structure is simple, sturdy and durable, easy to operate, safe and reliable, requires little maintenance, and is easy to install. It can greatly improve work efficiency and reduce production costs.

[0009] 4. The unique structural design of this utility model, with the displacement adjustment device on the lifting device, avoids the spring tilting phenomenon caused by the change of the fulcrum of the damping spring when the tilt angle of the feeder trough is adjusted, making the operation more stable and safer.

[0010] 5. The present invention employs a novel trough inclination adjustment device for a seated feeder, which is particularly suitable for situations where the trough inclination angle of a seated feeder needs to be adjusted at any time according to changes in the looseness and viscosity of the material.

[0015] Comparison Figures 1-3 A novel seat-type feeder trough tilt angle adjustment device comprises a displacement adjustment device, a lifting device, a fixed seat, an active slide, an electro-hydraulic actuator, a gear set, and a passive slide. Its features include: a vibration damping spring at the front opening of the feeder trough rests on the displacement adjustment device 1; rollers 1.1 are installed inside the displacement adjustment device 1; a lifting device 2 is located below the displacement adjustment device 1; a support seat 2.1 is installed in the middle of the lifting device 2; rollers 2.2 are installed at the lower part of the support seat 2.1; and a fixed seat 3 is located inside the lifting device 2. An active slide 4 is installed on one side inside the seat 3. The lower part of the active slide 4 is provided with an upper rack 4.1. The lower part of the upper rack 4.1 is connected to the gear set 6. The lower part of the gear set 6 is connected to the lower rack 7.1 installed on the lower part of the passive slide 7 inside the fixed seat 3. The roller 2.2 is on top of the active slide 4 and the passive slide 7. The lower part of the passive slide 7 is connected to the fixed seat 3. The electro-hydraulic actuator 5 is installed on the outside of the fixed seat 3 through the actuator support 5.1. The front end of the electro-hydraulic actuator 5 passes through one side of the fixed seat 3 and is connected to the active slide 4.

[0016] The working principle of a novel seated feeder trough inclination adjustment device is as follows: The device is placed under the damping spring at the front of the seated feeder. An electro-hydraulic actuator pushes the active slide within the fixed base. The upper rack below the active slide drives the gear set to rotate, which in turn drives the lower rack below the passive slide to move. This causes the active and passive slides to move towards each other, forming an angle between the inclined surfaces. As the angle between the two slides increases, the rollers drive the lifting device, the displacement adjustment device, and the feeder damping spring to rise. The damping springs then cause the feeder trough inclination angle to decrease. Conversely, as the angle between the two slides decreases, the rollers drive the... The lifting device, along with its displacement adjustment device and the feeder's damping spring, descends. The damping spring causes the feeder trough angle to increase accordingly. The included angle between the two inclined planes has a self-locking function with the rollers, achieving stepless height adjustment of the feeder trough angle. This allows for operation based on changes in material bulkness and viscosity, making it convenient and effectively solving the problem of excessive feed rate for dry, easily flowing materials, and insufficient feed rate for materials with high moisture content and high viscosity, thus reducing production efficiency. Furthermore, the displacement adjustment device prevents spring tilting caused by changes in the damping spring's fulcrum during trough angle adjustment, resulting in smoother operation and higher safety. This invention utilizes an external electro-hydraulic actuator to drive an internal mechanical transmission mechanism. The structure is simple, robust, durable, easy to operate, requires minimal maintenance, and is easy to install, significantly improving work efficiency and reducing production costs. It is particularly suitable for applications where the trough angle of a seated feeder needs to be adjusted according to changes in material bulkness and viscosity.
