[0067] In a specific embodiment, such as Figure 1 、 Figure 2 and Figure 3 shown, there are two water spraying devices, namely a left water spraying device 128a and a right water spraying device 128b.

[0070] That is to say, during the working process of the roadheader, the tunneling mechanism tunnels and generates materials; the loading mechanism 100 can effectively collect the materials to sweep the materials into the transfer chute 110; the materials entering the transfer chute 110 are conveyed to a designated position under the combined action of the scraper chain and the scraper conveyor.

Specific embodiment:

[0073] The present invention provides a hydraulic-driven loading mechanism 100 for a roadheader-anchoring machine. Among them, as Figure 1 , Figure 2 and Figure 3 shown, the loading mechanism 100 includes: a main body 102, a left door panel 104a, a right door panel 104b, a left telescopic oil cylinder 106a, a right telescopic oil cylinder 106b, a deflection wheel 130, a left star wheel drive assembly 108a, and a right star wheel drive assembly 108b. The loading mechanism 100 is connected to the scraper conveyor by a scraper chain; the left star wheel drive assembly 108a and the right star wheel drive assembly 108b sweep the incoming material onto the scraper chain by reverse rotation; the left door panel 104a and the right door panel 104b are respectively connected to the main body 102 by the left telescopic oil cylinder 106a and the right telescopic oil cylinder 106b, and the overall width of the loading mechanism 100 is controlled by the telescopic movement of the telescopic oil cylinder; the main body 102 is integrally welded to ensure its strength requirements.

[0074] Furthermore, the above-mentioned star wheel drive assembly, as Figure 4 and Figure 5 shown, includes: a hydraulic motor 132, a spline shaft 114, tapered roller bearings, a flange cover 116, a star wheel 134, and a floating seal. Among them, the hydraulic motor 132 is connected to the main body 102 through a connecting component 124, and the star wheel 134 is connected to the flange cover 116 through a positioning pin and bolts 136. When the star wheel drive assembly is working, the hydraulic motor 132 drives the spline shaft 114 to rotate, thereby driving the flange cover 116 and the star wheel 134 to rotate. The seal adopts a combination of floating seal and mechanical labyrinth seal to ensure the tightness of the seal.

[0075] The present invention abandons the traditional motor-driven method and instead uses the hydraulic motor 132 for driving, avoiding production stoppages caused by motor failures and improving production efficiency; the left door panel 104a and the right door panel 104b are telescopic, enabling the loading mechanism 100 to meet the aggregate work requirements of different roadway widths and realizing the function of multi-purpose use of one machine.

[0076] Next, the above-mentioned loading mechanism 100 will be further described in conjunction with the attached Figures 1 to 5 :

[0077] The loading mechanism 100 proposed by the present invention has its tail connected to the scraper conveyor. Part of the deflection wheel 130 can pass through the scraper chain and be integrated with the rear scraper conveyor. The rotation of the star wheel 134 causes the material to fall into the scraper chain, and then it is transported by the scraper conveyor; as Figure 1 , Figure 2 and Figure 3As shown in the figure, the entire device mainly includes: a main body, a left door panel 104a, a right door panel 104b, a left star wheel drive assembly 108a, a right star wheel drive assembly 108b, a deflection wheel 130, a left telescopic oil cylinder 106a, a right telescopic oil cylinder 106b, a left water spraying device 128a, and a right water spraying device 128b. The above loading mechanism 100 can be used for the aggregate work of a roadheader, and more specifically, can be used to collect materials such as coal in a coal mine.

[0078] Specifically, the main body 102 is integrally welded to ensure the strength of the entire loading mechanism 100 and its supporting function.

[0079] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, the left door panel 104a and the right door panel 104b are located on the left and right sides of the transfer chute 110, and are respectively connected to the main body 102 through the left telescopic oil cylinder 106a and the right telescopic oil cylinder 106b, enabling the left door panel 104a and the right door panel 104b to have the function of opening and closing, so that the loading mechanism 100 can adapt to roadway operations of different widths.

[0080] Specifically, as Figure 4 and Figure 5 shown, the star wheel drive assembly mainly includes: a hydraulic motor 132, a spline shaft 114, a base 112, a floating seal, a tapered roller bearing, a star wheel 134, a flange cover 116, etc.; among them, the hydraulic motor 132 and the base 112 are fixed together through a connecting component 124; the flange cover 116 is matched with the spline shaft 114, the inner ring of the bearing 118 is matched with the flange cover 116, and the outer ring is matched with the non-rotating part base 112. One end of the bearing 118 is tightened by a nut 120 and is equipped with a thrust washer 122.

[0081] The entire device is the main power source for the loading mechanism 100 to collect aggregates. As Figure 4 and Figure 5 shown, during operation, the hydraulic motor 132 drives the spline shaft 114 to rotate, thereby driving the flange cover 116 and the star wheel 134 connected to it by bolts 136 to rotate for aggregate collection; the entire structure is fixed to the main body 102 through the threaded holes on the base 112 and the connecting component 124, and the base 112 is separated from the rotating part by the bearing 118. In terms of sealing, a floating seal plus a mechanical labyrinth seal is used.

[0082] Specifically, the scraper chain connects the scraper conveyor and the loading mechanism 100 through the deflection wheel 130, enabling the materials to be transported out through the scraper conveyor in a timely manner.

[0083] The loading mechanism 100 proposed by the present invention has at least the following advantages:

[0084] 1. Achieve the aggregate work in a more complex environment of coal mines. Compared with the motor drive in the related technology, through the optimization of the structure and the use of the hydraulic motor 132, the loading mechanism 100 can work normally in a complex environment with a lot of water and mud.

[0085] Specifically, the driving part of the star wheel 134 is the hydraulic motor 132, which can adapt to a more complex underground environment compared with the motor. In an environment with a lot of water and mud, the situation of motor burnout in the traditional mode of motor plus reducer is effectively avoided, ensuring the continuous progress of the production work of the mining party.

[0086] 2. Realize the function of using one device in multiple roadways. The opening and closing of the left door panel 104a and the right door panel 104b enable the loading mechanism 100 to adapt to roadways of different widths, and also make the aggregate work more thorough.
