[0034] Figure 4 A top cover, the main body of which is a cover plate 2, installed at the feeding port on the top of the casing 1, such as a crusher, screening machine, etc.

[0035] like Figure 3 As shown, a feeding trough 3 is provided on the cover plate 2. The left end of the baffle 4 is rotatably installed in the feeding trough 3 via a rotating shaft 5. An elastic support mechanism is provided at the bottom of the baffle 4 to provide elastic support for the baffle 4 so that it can remain in the state of covering the feeding trough 3.

[0036] Specifically, such as Figure 4 As shown, the elastic support mechanism includes an arc-shaped rod 6, an arc-shaped groove 7, and an arc-shaped spring 8. The bottom of the baffle 4 is fixedly installed with the arc-shaped rod 6, and the end of the arc-shaped rod 6 is movably inserted into the arc-shaped groove 7 and supported by the arc-shaped spring 8. The arc-shaped groove 7 is opened at the bottom of the cover plate 2, wherein the virtual center position of the arc-shaped rod 6 coincides with the installation position of the rotating shaft 5.

[0037] The cover plate 2 and the baffle plate 4 can effectively cover the feeding port of the machine casing 1, preventing waste from splashing to the outside during the crushing process and reducing the risk of injury to operators. At the same time, the baffle plate 4 is supported by an elastic support mechanism and can also open automatically under the action of gravity when feeding, without affecting the feeding.

[0038] During feeding, the baffle 4 will deflect under the action of gravity of the material, and the arc spring 8 will be compressed through the arc rod 6. At this time, the material can slide into the machine casing 1 along the baffle 4.

[0039] In the embodiment, a blocking strip 9 is fixedly installed in the feeding groove 3, and is used for blocking the upward movement of the other end of the baffle 4, so that the baffle 4 can be kept in a horizontal state.

[0040] As shown in Figure 4 , a gas collecting pipe 10 is further arranged and is embedded in the cover plate 2, the bottom of the gas collecting pipe 10 is uniformly provided with an air suction pipe 11, the bottom end of the air suction pipe 11 protrudes from the cover plate 2, and a filter screen cylinder 13 is arranged on the bottom end of the air suction pipe 11, the filter screen cylinder 13 is fixedly installed on the bottom of the cover plate 2, and is used for blocking large-particle impurities;

[0041] The top of the gas collecting pipe 10 is connected with a negative pressure device (such as a fan) through an air suction pipe 12, and is used for generating suction force, when the negative pressure device is operated, dust generated in the crushing process can be effectively extracted through the air suction pipe 12, the gas collecting pipe 10 and the air suction pipe 11, the dust is prevented from spreading in the air, the pollution to the operating environment is avoided, and the health of the workers is avoided from being harmed.

[0042] In the embodiment, clamping plates 14 are movably arranged at the two ends of the cover plate 2, and are used for clamping, so that the cover plate 2 can be fixed at the feeding opening of the machine shell 1.

[0043] Specifically, as shown in Figure 3 and Figure 4 , threaded rods 15 are rotatably installed at the ends of the cover plate 2, nuts are threadedly connected to the outer walls of the threaded rods 15, the nuts are fixedly installed on the clamping plates 14, sliding plates 16 are fixedly installed on the clamping plates 14, and the sliding plates 16 are slidably installed on the cover plate 2.

[0044] Through the sliding of the sliding plates 16 on the cover plate 2, the rotation of the clamping plates 14 can be limited, so that the clamping plates 14 can only move in a translational manner, and then when the threaded rods 15 are rotated, the nuts and the clamping plates 14 can be driven to move, so that the entire cover plate 2 can be clamped and fixed at the feeding opening of the machine shell 1.

[0045] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
