[0035] In order to enable those skilled in the art to better understand the present invention, and thus to more clearly define the scope of protection claimed by the present invention, the present invention is described in detail below with respect to certain specific embodiments of the present invention. It should be noted that the following are only certain specific implementation methods of the present invention, which are only part of the embodiments of the present invention, wherein the specific and direct description of the relevant structures is only for the convenience of understanding the present invention, and each specific feature does not naturally and directly limit the scope of implementation of the present invention. The conventional selections and substitutions made by those skilled in the art under the guidance of the present invention shall be deemed to be within the scope of protection claimed by the present invention.

[0036] like Figure 1-Figure 7 As shown, the utility model discloses a dust-proof transmission system, comprising:

[0037] A dust cover 1 is provided inside the dust cover 1, and a dust cover cavity 11 extending leftward and rightward is provided inside the dust cover 1. An inlet 12 is provided above the left end of the dust cover 1, and an outlet 13 is provided below the right end of the dust cover 1. The inlet 12 and the outlet 13 are respectively connected to the dust cover cavity 11.

[0038] Conveyor belt 2, the conveyor belt 2 is arranged in the dustproof chamber 11, and the conveyor belt 2 is used to transfer the material from the inlet 12 to the outlet 13. Specifically, the conveyor belt 2 is supported by a driving roller and a driven roller, and the driving roller is driven by a motor to rotate so that the upper end of the conveyor belt 2 is transferred from left to right;

[0039] The limiting baffle 3, the number of the limiting baffle 3 is two, and they are respectively arranged on both sides of the width of the conveyor belt 2, and the limiting baffle 3 is respectively fixed to the dust cover 1. In addition, the lower end of the limiting baffle 3 is provided with a baffle plate 31 that abuts against the upper surface of the conveyor belt 2, and the baffle plate 31 is made of elastic material.

[0040] Therefore, 1. The material to be transported is poured into the dustproof chamber 11 through the feed port 12 and falls onto the conveyor belt 2. The conveyor belt 2 transports the material from left to right so that the material is transported to the end of the conveyor belt 2 and leaves the conveyor belt 2, and falls from the discharge port 13 under the action of gravity to complete the transmission; 2. The material on the conveyor belt 2 is restricted by the material blocking member and cannot escape from the conveyor belt 2, so as to prevent the problem of material falling on the width side of the conveyor belt 2 during the transmission process. In addition, the raised dust and splashed materials are difficult to escape from the range of the conveyor belt 2 under the action of the limiting baffle 3, which plays a first dust-proof effect; 3. The dustproof chamber 11 plays a second dust-proof effect outside, so that a small amount of dust raised from the limiting baffle 3 and materials splashed from the limiting baffle 3 cannot escape under the action of the dustproof chamber 11; 4. The material baffle plate 31 is made of elastic material, so that the matching sealing of the material baffle plate 31 and the conveyor belt 2 is better.

[0041] Specifically, the distance between the upper end of the limiting baffle 3 and the inner top wall of the dustproof cavity 11 is h, and h≤3 mm.

[0042] Specifically, the material of the baffle plate 31 is rubber material or silicone material.

[0043] Among them, the two limiting baffles 3 in this embodiment extend upward and are close to each other, so that the material channel formed by the combination of the limiting baffle 3 and the conveyor belt 2 has a structure that is wide at the bottom and narrow at the top. This structure is the same as the stacking of materials under the action of gravity, so as to ensure the conveying capacity while reducing the volume of the material channel, so that the raised dust is more easily restricted by the material channel and falls back, so as to reduce dust.

[0044] In other embodiments, only the limiting baffle 3 on one side is arranged to be inclined.

[0045] In addition, the material baffle plate 31 is arranged in close contact with the limiting baffle plate 3 so that the material baffle plate 31 is arranged at an angle. The material baffle plate 31 is provided with a first surface 311 and a second surface 312 which are perpendicular to each other. A sealing line 313 is arranged at the intersection of the first surface 311 and the second surface 312. The sealing line 313 is against the upper surface of the conveyor belt 2, so that the material baffle plate 31 in the inclined state uses the sealing line 313 as a contact structure to achieve a line seal with the conveyor belt 2, the contact area is smaller, the friction resistance is smaller, and the transmission of the conveyor belt 2 is smoother.

[0046] Preferably, the baffle plate 31 in this embodiment is arranged on the side of the corresponding limiting baffle 3 away from the other limiting baffle 3, and a mounting pressure plate 32 is provided on the side of the baffle plate 31 away from the limiting baffle 3. The mounting pressure plate 32 and the limiting baffle 3 are clamped between the mounting pressure plate 32 and the limiting baffle 3 by the cooperation of bolts and nuts to fix the baffle plate 31.

[0047] Therefore, 1. the material baffle plate 31 is fixed to the limiting baffle 3 by pressing the mounting pressure plate 32; 2. the mounting pressure plate 32 and the material baffle plate 31 are both arranged on the side of the limiting baffle 3 away from the other limiting baffle 3, so that the structure of the side of the limiting baffle 3 facing the other limiting baffle 3 is simpler and flatter, thereby making the material transmission smoother.

[0048] In addition, a mounting bracket 4 is provided in the dustproof chamber 11 in the present embodiment, and a U-shaped mounting slot 33 is provided at the upper end of the limiting baffle 3 by stamping and bending, and the U-shaped opening of the mounting slot 33 faces away from the other limiting baffle 3. The mounting bracket 4 is inserted into the mounting slot 33 and is fixedly connected to the limiting baffle 3 by bonding, welding, clamping, bolting, etc.

[0049] Therefore, a U-shaped installation slot 33 is provided at the upper end of the limiting baffle 3 so that the upper end of the limiting baffle 3 is used for fixing, so that the lower end structure is simpler and the material transmission is smoother. In order to form the installation slot 33, a bending structure is formed at the upper end of the limiting baffle 3, and the bending structure extends toward the other limiting baffle to have a better limiting effect on dust.

[0050] In addition, the mounting bracket 4 in this embodiment includes a fixed frame 41 and an adjustment frame 42. The fixed frame 41 is fixedly arranged on the dust cover 1, and the adjustment frame 42 is slidably arranged on the fixed frame 41 along the width direction of the conveyor belt 2, so that the position of the limiting baffle 3 relative to the conveyor belt 2 and the relative distance between the two limiting baffles 3 can be adjusted by sliding the adjustment frame 42 relative to the fixed frame 41, so as to better adapt to different transmission conditions.

[0051] Specifically, the fixing frame 41 is in a 7-shape, and the lower end of the vertical section of the 7-shaped fixing frame 41 is fixedly installed on the dust cover 1 by means of bolts, and a plurality of first mounting sockets 411 extending horizontally along the width direction of the conveyor belt 2 are provided on the transverse section of the 7-shaped fixing frame 41. Correspondingly, the adjustment frame 42 is provided with second mounting sockets 421 extending horizontally along the width direction of the conveyor belt 2, so that the first mounting sockets 411 and the second mounting sockets 421 are aligned and matched with bolts and nuts to realize the fixed installation of the adjustment frame 42 and the fixing frame 41.

[0052] Among them, the upper left end of the dust cover 1 in this embodiment is provided with an upwardly flared feed hopper 5, and the feed port 12 is arranged above the feed hopper 5, so that after the material is poured in, it enters the dustproof cavity 11 after being gathered and falls on the conveyor belt 2.

[0053] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
