Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeder technology, specifically to a feeder with adjustable gap. Background Technology
[0002] During the feeding process of a granular material feeder, due to changes in material particle size or internal wear from long-term use of the feeding equipment, jamming can easily occur between the feeder blades and the feeder chassis. This not only affects the particle size of the material but also easily leads to equipment shutdown. In existing technologies, when jamming occurs, it is usually necessary to disassemble the equipment and add shims under the rotor bearing to adjust the gap between the blades and the chassis. The loading and unloading process is cumbersome and time-consuming, which seriously affects the feeding efficiency of the feeder. Utility Model Content
[0003] The purpose of this utility model is to address the above-mentioned shortcomings by providing a feeder with an adjustable gap, which facilitates the adjustment of the gap between the feeder blades and the feeder chassis without disassembling the equipment, thus ensuring the feeder's feeding efficiency.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An adjustable gap feeder includes a cylindrical hollow feed housing, a feed pipe connected to the feed housing at its top, a feed inlet at the top of the feed housing, a base fixed to the bottom of the feed housing, a through hole vertically disposed in the base, multiple slide rails vertically disposed in the upper half of the through hole, an internal thread disposed in the lower half, a slider screwed to the internal thread, a bearing fixedly connected to the top of the slider on its outer ring, a lifting seat fixed to the inner ring of the bearing, a lifting shaft fixedly disposed at the bottom of the slider, and a rotating shaft disposed above the lifting seat. An adjusting block is fixedly disposed at the bottom of the lifting shaft, one end of the rotating shaft extends into the feed housing and is provided with feed blades, a motor is mounted on the top of the lifting seat, the motor is used to drive the rotating shaft to rotate, the rotating shaft is slidably connected to the feed housing, a connecting block is slidably connected to the slide rails, and one end of the connecting block is fixedly connected to the lifting seat.
[0006] Furthermore, the outer edge of the adjustment block is hexagonal.
[0007] Furthermore, the outer diameter of the unloading housing is larger than the outer diameter of the chassis.
[0008] Furthermore, multiple stiffening plates are welded to one side of the chassis to connect with the unloading shell.
[0009] The beneficial effects of this utility model are:
[0010] In practical applications, granular materials enter the feeding housing through the feed inlet. The motor drives the rotating shaft to rotate the feeding blades, scraping the granular materials falling into the feeding housing onto the feed end of the feeding pipe. Since the slider is screwed with an internal thread, when it is necessary to adjust the gap between the feeder blades and the feeder base, the adjusting block is rotated. The adjusting block raises the motor, rotating shaft, and feeding blades through the lifting shaft, slider, bearing, and lifting seat, adjusting the gap between the feeding blades and the bottom of the feeding housing. This eliminates the need to disassemble the equipment, making it convenient to use. This utility model facilitates the adjustment of the gap between the feeder blades and the feeder base without disassembling the equipment, ensuring the feeding efficiency of the feeder.

[0015] like Figure 1 , Figure 2 and Figure 3 As shown, an adjustable gap feeder includes a cylindrical hollow feed housing 1, a feed pipe 2 connected to the top of the feed housing 1, a feed inlet located at the top of the feed housing 1, a base 3 fixed to the bottom of the feed housing 1, a through hole vertically disposed within the base 3, multiple slide rails 30 vertically disposed in the upper half of the through hole, and an internal thread 31 disposed in the lower half, a slider 4 screwed onto the internal thread 31, a bearing 5 fixedly connected to the top of the slider 4 on its outer ring, and a lifting seat 6 fixed on the inner ring of the bearing 5, with the top fixed... A lifting shaft 7 is fixed at the bottom of the slider 4, and a rotating shaft 8 is set above the lifting seat 6. An adjusting block 9 is fixed at the bottom of the lifting shaft 7. One end of the rotating shaft 8 extends into the feeding housing 1 and is provided with feeding blades 10. A motor 11 is installed at the top of the lifting seat 6. The motor 11 is used to drive the rotating shaft 8 to rotate. The rotating shaft 8 is slidably connected up and down in the feeding housing 1. A connecting block 32 is slidably connected up and down on the slide rail 30. One end of the connecting block 32 is fixedly connected to the lifting seat 6.
[0016] In use, granular material enters the feeding housing 1 through the feed inlet. The motor 11 drives the rotating shaft 8 to rotate the feeding blades 10, scraping the granular material falling into the feeding housing 1 onto the feed end of the feeding pipe 2. Since the slider 4 is screwed with the internal thread 31, when it is necessary to adjust the gap between the feeding blades and the feeding base 3, the adjusting block 9 is rotated. The adjusting block 9 raises or lowers the motor 11, rotating shaft 8 and feeding blades 10 through the lifting shaft 7, slider 4, bearing 5 and lifting seat 6. At this time, the connecting block 32 slides up or down along the slide rail 30 to adjust the gap between the feeding blades 10 and the bottom of the feeding housing 1. The equipment does not need to be disassembled, making it convenient to use. During the process of the motor 11 driving the rotating shaft 8 to rotate the feeding blades 10, the lifting seat 6 is limited by the connecting block 32 and the slide rail 30 to prevent it from rotating with the motor 11. This utility model facilitates the adjustment of the gap between the feeding blades and the feeding base 3 without disassembling the equipment, ensuring the feeding efficiency of the feeding device.
[0017] like Figure 1 , Figure 2 and Figure 3 As shown, the outer edge of the adjusting block 9 is hexagonal; in this embodiment, when the outer edge of the adjusting block 9 is hexagonal, the adjusting block 9 can be locked and rotated by a wrench, making rotation more convenient.
[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the outer diameter of the feeding housing 1 is larger than the outer diameter of the chassis 3; in this embodiment, when the outer diameter of the feeding housing 1 is larger than the outer diameter of the chassis 3, the feeding speed is faster.
[0019] like Figure 1 , Figure 2 and Figure 3 As shown, multiple stiffening plates 12 connecting the unloading shell 1 are welded to one side of the chassis 3; in this embodiment, by welding multiple stiffening plates 12 connecting the unloading shell 1 to one side of the chassis 3, the connection strength between the chassis 3 and the unloading shell 1 can be strengthened.
[0020] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the scope defined by the spirit of this utility model.
