[0024] Example:

[0025] See also Figure 1-4 , the utility model provides a technical solution:

[0026] A coal mine excavation support device, comprising a support plate 1, a lower side wall of the support plate 1 is fixedly provided with a uniformly arranged support mechanism, the lower ends of the uniformly arranged support mechanisms are fixedly provided with a mounting plate 2, an upper side wall of the support plate 1 is fixedly provided with an arc-shaped fixed plate 3, a first support plate 4 is fixedly provided inside the arc-shaped fixed plate 3, a buffer mechanism is fixedly provided at the upper end of the first support plate 4, and a second support plate 5 is fixedly provided at the upper end of the buffer mechanism;

[0027] The left and right ends of the lower side wall of the second supporting plate 5 are fixedly provided with vertical plates 6, and the sides of the two vertical plates 6 close to each other are fixedly provided with chassis 7, and the insides of the two chassis 7 are fixedly provided with motors 8, and the output ends of the two motors 8 are fixedly provided with rotating rods 9, and the two rotating rods 9 extend through the vertical plates 6 to the other end and are fixedly provided with collecting grooves 10, and the side walls of the collecting grooves 10 are fixedly provided with limiting rods 11, and the side walls of the vertical plates 6 are provided with annular grooves, and the inside of the annular grooves is slidably provided with limiting blocks 12, and the other end of the limiting rod 11 is fixedly connected to the side wall of the limiting block 12;

[0028] A slide groove is provided at the front end of the inner wall of the collecting trough 10, and a baffle 13 is slidingly arranged inside the slide groove. A fastening bolt is threadedly arranged on the side wall of the collecting trough 10, and the other end of the fastening bolt is clamped with the baffle 13. The present application cooperates with the motor 8, the rotating rod 9, the collecting trough 10, the limiting rod 11, the limiting block 12 and the baffle 13 to facilitate the rocks to fall directly into the collecting troughs 10 on both sides after being blocked by the second supporting plate 5. When a certain amount is collected, they are processed centrally, which effectively avoids the rocks from rolling onto the road after passing through the second supporting plate 5 and affecting normal traffic, and does not require a large amount of manpower to handle.

[0029] The supporting mechanism includes a first supporting rod 14 and a second supporting rod 15. The first supporting rod 14 is fixedly connected to the upper side wall of the mounting plate 2. The second supporting rod 15 is slidably arranged inside the first supporting rod 14. The upper end of the second supporting rod 15 is fixedly connected to the lower side wall of the supporting plate 1. The side wall of the first supporting rod 14 is threaded with an adjusting threaded knob 16. The other end of the adjusting threaded knob 16 is clamped with the side wall of the second supporting rod 15. The supporting mechanism can adjust the length of the second supporting rod 15 and the first supporting rod 14, thereby adjusting the height of the first supporting plate 4 and the second supporting plate 5.

[0030] Symmetrical fixing piles 17 are slidably provided on the side wall of the mounting plate 2 to fix the mounting plate 2 to the ground.

[0031] The buffer mechanism includes a telescopic rod 18, which is fixedly connected to the upper side wall of the first supporting plate 4, and the upper end of the telescopic rod 18 is fixedly connected to the lower side wall of the second supporting plate 5. A spring 19 is provided on the outer sleeve of the telescopic rod 18, and the upper end of the spring 19 is fixedly connected to the lower side wall of the second supporting plate 5, and the lower end of the spring 19 is fixedly connected to the upper side wall of the first supporting plate 4. When the falling rock contacts the second supporting plate 5, the inertia of the stone can be effectively buffered to prevent it from rebounding again after contacting the second supporting plate 5, so that it can roll along the second supporting plate 5 to the inside of the collecting trough 10 after contacting.

[0032] The side wall threads of the arc-shaped fixing plate 3 are provided with evenly arranged fixing bolts, and the first supporting plate 4 is fixedly connected to the arc-shaped fixing plate 3 via the fixing bolts.

[0033] A handle is fixedly provided on the lower side wall of the baffle 13, so that when the baffle 13 needs to be opened, the baffle 13 can be opened by pulling down the handle.

[0034] Working principle:

[0035] The supporting height of the first supporting plate 4 and the second supporting plate 5 is adjusted through the supporting mechanism, and the supporting device is fixed to the ground through the cooperation of the mounting plate 2 and the fixing pile 17. When the falling rocks fall, they first contact the second supporting plate 5, and in the process of collision, they will cooperate with the buffer mechanism to prevent the falling rocks from hitting a second time and bouncing to a farther position, so that they can roll along the second supporting plate 5 to the inside of the collecting trough 10 after hitting as much as possible. When it is necessary to deal with the falling rocks inside regularly, the limiting effect of the fastening bolts on the baffle 13 is released, the baffle 13 is pulled down, and the motor 8 is started. The motor 8 drives the rotating rod 9 at the output end to rotate, and the rotating rod 9 drives the collecting trough 10 to rotate. The collecting trough 10 concentrates the stones inside and pours them into the transportation tool, which is convenient and quick, and the falling rocks will not roll onto the walking road to affect traffic.
