The vibrating feeder can achieve uniform material conveying and preliminary screening, and is widely used in mining, metallurgy, building materials and other industries. In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art: During the screening process, the grate bars of the feeder are prone to clogging due to impurities or excessively large particles in the material, which reduces the screening efficiency of the feeder and may even affect the normal operation of the equipment. Utility Model Content

[0003] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0004] This disclosure provides a feeder anti-clogging grate device to solve the problem of feeder grate bars easily getting stuck and blocked.

[0005] In some embodiments, the feeder anti-blocking grate bar device includes: two support frames arranged parallel to each other, each support frame having a mounting groove in its center; several grate bars arranged side-by-side between two support frames, each grate bar being perpendicular to the support frame; mounting plates respectively disposed at both ends of the grate bars, with positioning bolts inserted into both sides of the mounting plates, the positioning bolts passing through the mounting grooves, and positioning nuts threadedly connected to the positioning bolts, the positioning nuts being disposed on the side of the mounting groove away from the mounting plate; and a spring assembly disposed on the side of the mounting plate away from the support frames, with the end of the positioning bolt away from the support frame pressing against the spring assembly.

[0006] In some embodiments, a support plate is provided between the mounting plate and the grate bar.

[0007] In some embodiments, a positioning plate is provided on the side of the support frame away from the mounting plate, and the positioning bolt is inserted through the mounting plate.

[0008] In some embodiments, the positioning bolts are respectively disposed on the mounting plates on both sides of the grate bar.

[0009] In some embodiments, the support frame is provided with connecting plates at both ends, and the connecting plates are provided with connecting holes.

[0010] In some embodiments, the grate bar is a frustum structure with a long strip shape.

[0011] In some embodiments, the plurality of grate bars are arranged relatively parallel to each other.

[0012] In some embodiments, ribs are provided on the sides of the support frame.

[0013] In some embodiments, the mounting plates are arranged side-by-side close to each other.

[0014] In some embodiments, the thickness of the support plate is less than the diameter of the grate bar.

[0015] The anti-clogging grate device for the feeder provided in this embodiment can achieve the following technical effects: The spring assembly elastically presses the grate bars onto the support frame, allowing the grate bars to produce controllable micro-oscillations when subjected to material impact or vibration. This effectively prevents material from getting stuck in the gaps between the grate bars and improves screening efficiency. The grate bars are long and cylindrical in shape, with gradually widening gaps in the direction of material flow. This allows the material to pass through the gaps in the grate bars more smoothly, reducing the risk of blockage.

[0027] Combination Figure 1-5 As shown in the figure, this disclosure provides a feeder anti-blocking grate bar device, including: two support frames 100, which are arranged relatively parallel to each other, and a mounting groove 101 is provided in the middle of each support frame 100; several grate bars 200, which are arranged side by side between two support frames 100 and are arranged relatively perpendicular to each support frame 100; mounting plates 201 are respectively disposed at both ends of the grate bars 200, and positioning bolts 202 are inserted into both sides of the mounting plates 201. The positioning bolts 202 pass through the mounting groove 101, and positioning nuts 204 are threadedly connected to the positioning bolts 202. The positioning nuts 204 are disposed on the side of the mounting groove 101 away from the mounting plate 201; and a spring assembly 205 is disposed on the side of the mounting plate 201 away from the support frame 100, with the end of the positioning bolt 202 away from the support frame 100 pressed onto the spring assembly 205.

[0028] Using the anti-clogging grate bar 200 device for the feeder provided in this embodiment, the support frame 100 can be fixedly connected to the vibrating feeder. The support frame 100 is used to support the grate bar 200. Two support frames 100 are arranged side by side and vertically. Both ends of the grate bar 200 are connected to the two support frames 100 through mounting plates 201 respectively. The mounting plates 201 facilitate the installation of the grate bar 200. A positioning bolt 202 is inserted into the mounting plate 201. The other end of the positioning bolt 202 passes through the mounting groove 101. The upper end of the positioning bolt 202 is close to the mounting plate 201. A spring assembly 205 is provided, which can be pressed onto the upper part of the mounting plate 201 by the positioning bolt 202. The positioning bolt 202 can also press the mounting plate 201 onto the support frame 100. The positioning bolt 202 passes through the mounting groove 101, and the other end of the positioning bolt 202 passing through the mounting groove 101 is threadedly connected to the positioning nut 204. The pressing of the spring assembly 205 allows the grate bar 200 to tilt on the support frame 100. The tilting of the grate bar 200 can prevent the grate bar 200 from clogging during filtration.

[0029] Optionally, a support plate 206 is provided between the mounting plate 201 and the grate bar 200.

[0030] Thus, a support plate 206 is installed on the upper part of the mounting plate 201, and the grate bar 200 is installed on the support plate 206. This increases the swing range of the grate bar 200, thereby increasing the throughput of the grate bar 200. When the mounting plate 201 compresses the spring assembly 205, the support plate 206 and the grate bar 200 can tilt, which can prevent materials from getting stuck between the grate bars 200. The extension of the support plate 206 can increase the movement range of the grate bar 200, thereby better preventing materials from getting stuck in the grate bar 200.

[0031] Optionally, a positioning plate 207 is provided on the side of the support frame 100 away from the mounting plate 201, and the positioning bolt 202 is inserted through the mounting plate 201.

[0032] In this way, the positioning plate 207 can facilitate the installation and fixing of the positioning bolt 202, so that the positioning bolt 202 can be stably connected to the positioning plate 207 after passing through the mounting plate 201, and can also increase the connection strength between the positioning bolt 202 and the support frame 100.

[0033] Optionally, the positioning bolts 202 are respectively disposed on the mounting plates 201 on both sides of the grate bar 200.

[0034] In this way, the mounting plates 201 on both sides of the grate 200 can be subjected to force simultaneously, thereby ensuring the stability of the grate 200 during vibration. The positioning bolts 202 are set on both sides of the grate 200 to ensure uniform force distribution, which makes the grate 200 more stable when it returns to its original position after tilting, avoiding tilting or jamming caused by uneven force distribution.

[0035] Optionally, the support frame 100 is provided with connecting plates 102 at both ends, and the connecting plates 102 are provided with connecting holes 103.

[0036] In this way, the support frame 100 can be easily fixed to both sides of the vibrating feeder through the connecting holes 103 on the connecting plate 102, thereby ensuring the stability of the support frame 100. The connecting plate 102 can also strengthen the connection between the support frame 100 and the vibrating feeder, and can also facilitate the installation and replacement of the support frame 100.

[0037] Optionally, the grate bar 200 is a frustum structure with a long strip shape.

[0038] Thus, the grate 200 has an overall elongated frustum-shaped structure, with a trapezoidal cross-section. One end of the grate 200 is larger than the other. This design improves the smoothness of material passage, allowing smaller materials to be screened first, while larger materials continue to slide down the inclined direction of the grate 200. This allows smaller materials to be screened out first, and materials moving on the grate 200 can be screened sequentially. Furthermore, the frustum-shaped structure of the grate 200, with its inclined design (larger at the top and smaller at the bottom), allows materials to slide down the surface of the grate 200 more smoothly during the screening process, preventing blockages caused by the sliding material.

[0039] Optionally, the plurality of the grate bars 200 are arranged relatively parallel to each other.

[0040] In this way, the grate bars 200 are relatively parallel and evenly distributed, which allows the material to be evenly distributed among the grate bars 200 during the screening process, effectively improving screening efficiency and avoiding clogging problems caused by uneven material distribution.

[0041] Optionally, the support frame 100 is provided with ribs 104 on its side.

[0042] In this way, the ribs can enhance the structural strength of the support frame 100, prevent the support frame 100 from deforming or being damaged during long-term vibration, and also improve the wear resistance of the support frame 100 and extend its service life.

[0043] Optionally, the mounting plates 201 are arranged side by side in close proximity.

[0044] In this way, maintaining a certain distance between the mounting plates 201 can effectively prevent interference between adjacent grate bars 200 during vibration, and the distance between the grate bars 200 can be controlled by controlling the width of the mounting plates 201, thereby adapting to the screening requirements of materials with different particle sizes.

[0045] Optionally, the thickness of the support plate 206 is less than the diameter of the grate bar 200.

[0046] In this way, the thinner design of the support plate 206 can reduce the resistance of the material during the screening process, prevent the support plate 206 from obstructing the material falling between the grate bars 200, and at the same time, the support plate 206 can also play an auxiliary support role.
