Traditional vibrating screens generally have the following problems:
[0003] 1. Once the screen aperture is set, it is difficult to replace, and it cannot flexibly adapt to the screening requirements of grit with different particle sizes.
[0004] 2. The replacement process of the screen is complex after it is damaged, which affects the production progress.
[0005] 3. Although some high-end vibrating screens have good screening effects, their equipment costs are high and maintenance costs are expensive, which is not conducive to the use of small or medium-sized enterprises.

[0018] Furthermore, a plurality of fixing holes are provided at intervals on the outer ring of the support plate, and ground nails are provided in the fixing holes.
[0019] The beneficial effects of the present utility model are as follows:
[0020] 1. Enhance the flexibility of use: The design of the first slot on the side of the screen frame allows the first screen to slide in and out easily, which means that users can quickly replace screens with different pore sizes to meet the screening requirements of different particle sizes of gravel, ensuring the accuracy and flexibility of screening.
[0021] 2. Simplify the maintenance process: The detachable design of the screen makes the cleaning and replacement of the screen extremely simple, reducing the difficulty and cost of equipment maintenance and minimizing production downtime caused by equipment maintenance.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0029] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.
[0030] The present utility model provides a grit vibrating sieve table.
[0031] In this embodiment, referring to Figure 1 , the grit vibrating sieve table includes:
[0032] A middle frame 1, with feet 2 fixed to the bottom of the middle frame, and a lower spring sleeve 3 provided on the upper end surface of the middle frame;
[0033] A screen frame 4, with a lower spring sleeve 5 provided at the bottom of the screen frame, and a first slot 6 provided on the side surface of the screen frame;
[0034] A first screen 7, which is slidably inserted into the above-mentioned first slot;
[0035] A vibration spring 8, with both ends of the vibration spring fixedly connected to the lower spring sleeve and the upper spring sleeve respectively;
[0036] A material receiving frame 9, which is placed below the middle frame to catch the grit falling from the first screen.
[0037] When in use, by shaking the screen frame, the poured grit is screened through the first screen, and the falling grit is directly caught by the material receiving frame. When it is necessary to replace the screen with different pore sizes, only the first screen needs to be pulled out from the first slot, and the disassembly and replacement are very convenient. The overall structure of the device is simple and the cost is low.
[0038] Specifically, it further includes a second screen 10, with a second slot 11 provided on the side surface of the middle frame, and the second screen is slidably inserted into the above-mentioned second slot.
[0039] In the above technical solution, a second slot is added to the side surface of the middle frame to allow the second screen to be slidably inserted, realizing double-layer screening. Through the second screen, separation of grit with different particle sizes can be achieved, improving the screening fineness. The addition of the second screen enables the device to handle more complex screening tasks and has a wider application range.
[0040] Specifically, the aperture of the mesh holes of the first sieve is larger than that of the second sieve.
[0041] In the above technical solution, the aperture of the first sieve is larger than that of the second sieve, forming a screening order from coarse to fine. This ensures that the gravel is graded in an orderly manner according to the particle size, improving the accuracy of the screening result.
[0042] Specifically, handles 12 are provided on both sides of the mesh frame.
[0043] In the above technical solution, handles are added on both sides of the mesh frame, facilitating the operator to shake the mesh frame.
[0044] Specifically, a support plate 13 is provided at the bottom of the support leg.
[0045] In the above technical solution, a support plate is provided at the bottom of the support leg, increasing the contact area and improving the stability. The support plate increases the stability of the vibrating sieve table, preventing it from shaking during the screening process.
[0046] Specifically, a number of fixing holes 14 are spaced apart on the outer ring of the support plate, and ground nails 15 are provided in the fixing holes.
[0047] In the above technical solution, fixing holes are spaced apart on the outer ring of the support plate, and ground nails can be inserted into the holes to fix the vibrating sieve table. The use of the nails ensures the stability of the vibrating sieve table during vibration, avoiding unnecessary displacement.
[0048] All technical personnel should note that although the present utility model has been described according to the above specific embodiments, the idea of the present utility model is not limited to this utility model only. Any modification using the idea of the present utility model will be included in the protection scope of this patent right.
