[0002] The head of the transfer machine in the comprehensive mining working face is generally equipped with a coal collecting plate to improve the coal collecting effect on the belt conveyor after the transfer machine unloads coal, and to prevent coal scattering caused by uneven distribution on the belt after falling coal.

[0003] After searching, a Chinese patent with publication number CN218318913U discloses a retractable coal collecting plate of a transfer machine, including a coal blocking plate, a coal collecting plate, a coal skin, and a hydraulic cylinder. The coal collecting plate includes two groups of a first coal collecting plate and a second coal collecting plate that are fixedly connected as one. The lower end of the second coal collecting plate and the coal skin are fixedly connected by bolts and nuts. The coal blocking plates are symmetrically arranged on both sides of the head frame of the transfer machine. A short shaft is arranged at the bottom of the coal blocking plate near the extreme end of the transfer, and the short shaft is connected to the end of the first coal collecting plate away from the coal unloading direction. A slider is arranged in the middle position of the bottom of the coal blocking plate.

[0004] Although the above patent can timely adjust the overlap length of the coal retaining sheet and the belt to meet the transportation requirements of falling coal, the telescopic coal collecting plate in the above patent is difficult to control the lower coal collecting plate to align with the conveyor belt, resulting in the falling coal blocks damaging the loader and affecting the normal operation of the loader; for this reason, we provide a telescopic coal collecting plate for a transfer machine to solve the above problems.

When the transfer machine transports coal, the conveyor belt 6 is driven by the motor 4 to rotate and transport the coal to the outside. One end of the fixed frame 2 is fixedly connected to one side of the coal blocking plate 301, and one side of the coal blocking plate 301 is fixedly connected to one end of the first fixed bracket 302. The coal blocking plate 301 is supported by the fixed frame 2, and the coal blocking plate 301 can be installed on the transfer machine, which is convenient for cooperating with the transfer machine to work synchronously, and can also effectively protect the normal operation of the transfer machine.

[0031] See also Figure 2 and 4 The other end of the first fixed bracket 302 is rotatably connected to the fixed end of the first electric telescopic rod 303, and the telescopic end of the first electric telescopic rod 303 is rotatably connected to one end of the second fixed bracket 304. When the transfer machine moves forward, the vacancy left by the transfer machine is filled by the first electric telescopic rod 303 pushing the first coal collecting plate 305, which can effectively prevent coal from falling on the conveyor belt 6 on the transfer machine and causing damage to the transfer machine. The other end of the second fixed bracket 304 is fixedly connected to the upper end of one side of the first coal collecting plate 305, and the output shaft of the motor 4 is rotatably connected to the upper end of one side of the support plate 1. The first coal collecting plate 305 and the first electric telescopic rod 303 are fixed together through the second fixed bracket 304, which makes it convenient for the first electric telescopic rod 303 to drive the first coal collecting plate 305 to work, and the transfer machine can be protected at any time.

[0032] See also Figure 5The other end of the second fixed bracket 304 is fixedly connected to the upper end of one side of the first coal collecting plate 305, and a limiting groove 309 is provided on one side of the first coal collecting plate 305. The lower end of one side of the coal blocking plate 301 is fixedly connected to one end of the limiting rod 308, and the surface of the limiting rod 308 is slidably connected to the inside of the limiting groove 309. When the first electric telescopic rod 303 drives the first coal collecting plate 305 to work, the first coal collecting plate 305 rotates within the limiting range of the limiting groove 309. The limiting rod 308 supports the first coal collecting plate 305, which can prevent the first coal collecting plate 305 from falling during rotation. A sliding groove 306 is provided on the inner side of the first coal collecting plate 305. Through the three sliding grooves 306 provided on the first coal collecting plate 305, when the second coal collecting plate 307 needs to be adjusted, the slider 310 on the second coal collecting plate 307 can slide on the sliding groove 306, so as to facilitate the movement of the second coal collecting plate 307.

[0033] See also Figure 6 The interior of the slide groove 306 is slidably connected to the surface of the slider 310, and one end of the slider 310 is fixedly connected to the inner side of the second coal collecting plate 307. When the slider 310 slides, it drives the second coal collecting plate 307 to slide in the slide groove 306 on the first coal collecting plate 305, which can prevent the second coal collecting plate 307 from moving far away, while protecting the conveyor belt of the transfer machine. A telescopic device 3 is provided on one side of the fixed frame 2, and the telescopic device 3 includes a first coal collecting plate 305, the inner side of the first coal collecting plate 305 is fixedly connected to one end of the first fixed plate 311, and one side of the first fixed plate 311 is connected to the second electric telescopic rod The fixed end of 312 is fixedly connected, the telescopic end of the second electric telescopic rod 312 is fixedly connected to one side of the second fixed plate 313, and one end of the second fixed plate 313 is fixedly connected to the inner side of the second coal collecting plate 307. When the transfer machine moves forward, the first electric telescopic rod 303 drives the first coal collecting plate 305 to fill the epidemic gap of the transfer machine, which can prevent the damage caused by fallen coal blocks to the transfer machine. When the first electric telescopic rod 303 drives the first coal collecting plate 305 to adjust to a suitable position, the second electric telescopic rod 312 pushes the second coal collecting plate 307 to slide downward, and the conveyor belt of the transfer machine is protected for the second time.

[0034] Working principle: When in use, after the transfer machine moves forward, the first electric telescopic rod 303 drives the first coal collecting plate 305 to tilt up the front end, so that the rear end of the first coal collecting plate 305 is limited in the moving height under the action of the limit rod 308 and the limit groove 309. When the transfer machine moves forward, the first coal collecting plate 305 is driven to rotate by the first electric telescopic rod 303, and at the same time, the second electric telescopic rod 312 pushes the second coal collecting plate 307 to fill the empty position of the transfer machine, which can prevent the fallen coal from damaging the transfer machine. When the second electric telescopic rod 312 pushes the second coal collecting plate 307 to move, the slider 310 under the second coal collecting plate 307 slides at the slide groove 306 on the first coal collecting plate 305, which can effectively prevent the second coal collecting plate 307 from falling off when sliding, causing the second coal collecting plate 307 to be unable to continue to be used, effectively solving the problem that the conveyor belt of the transfer machine can be aligned with the second coal collecting plate 307, and effectively protecting the transfer machine.
