DETAILED DESCRIPTION

[0024] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0025] Example 1: A stone crushing device for mining, see Figure 1-Figure 3 and Figure 5-Figure 8 As shown, it includes a support frame 1, a crushing frame 2, a servo motor 3, a crushing roller 4 and a spur gear set 5. The crushing frame 2 is fixedly connected to the support frame 1. The servo motor 3 is arranged on the left side of the lower part of the crushing frame 2 by bolt connection. The crushing roller 4 is installed on the output shaft of the servo motor 3 through a coupling. The same crushing roller 4 is rotatably arranged in the lower part of the crushing frame 2. A spur gear set 5 is arranged between the right ends of the two crushing rollers 4. The spur gear set 5 consists of two gears, and the two gears are meshed with each other. It also includes a support plate 6, a flap 7, a rotating shaft 8 and a torsion spring 9. The support plate 6 is fixedly connected to the front and rear sides of the upper part of the crushing frame 2. The supporting plate 6 is rotatably arranged with a rotating shaft 8. The rotating shaft 8 is fixedly connected with a flap 7. The flap 7 is located above the crushing roller 4. The two flaps 7 are located in the crushing frame 2. Two torsion springs 9 are sleeved on the rotating shaft 8. The two ends of the torsion spring 9 are respectively connected to the crushing frame 2 and the support plate 6.

[0026] See also Figure 1-Figure 3 and Figure 8 As shown, a protective shell 22 is also included, and the left and right parts of the support plate 6 are fixedly connected to the protective shell 22, and the torsion spring 9 is located in the protective shell 22.

[0027] When it is necessary to crush the stone, first pour the stone into the crushing frame, so that the stone squeezes the flap 7 and the rotating shaft 8 to rotate, and the torsion spring 9 is deformed accordingly. The stone falls into the crushing frame 2 due to its weight. When all the stones fall into the crushing frame 2, the torsion spring 9 returns to its original state and drives the flap 7 and the rotating shaft 8 to reverse, so that the feed port on the crushing frame 2 can be blocked, thereby preventing fragments from splashing out during crushing, preventing stone fragments from injuring workers, and ensuring safety. Finally, the servo motor 3 is started, so that the output shaft of the servo motor 3 drives the crushing roller 4 on itself to rotate, and the rotation of the crushing roller 4 drives the gear of the spur gear set 5 to rotate. The two gears of the spur gear set 5 are meshed, so that it drives the other crushing roller 4 to rotate, so as to crush the stone. The crushed stone is discharged from the support frame 1 and collected by a pre-placed collection container. The protective shell 22 is used to protect the torsion spring 9.

[0028] Example 2: Based on Example 1, refer to Figure 2-Figure 4As shown, it also includes a water tank 10, a water pump 11, a connecting pipe 12 and a nozzle 13. The water tank 10 is fixedly connected to the rear side of the upper part of the crushing frame 2. The water pump 11 is provided at the bottom of the water tank 10 by bolt connection. The water pump 11 is connected to the connecting pipe 12. Both ends of the connecting pipe 12 are respectively located on the left and right sides of the crushing frame 2. Ten nozzles 13 are evenly spaced and connected to the left and right ends of the connecting pipe 12. The nozzles 13 are located in the crushing frame 2.

[0029] See also Figure 2 As shown, a transparent plate 21 is also included. The transparent plate 21 is embedded in the front side of the water storage tank 10.

[0030] When the stone is being crushed, the water pump 11 is started to draw water from the water tank 10, so that the water is drawn into the connecting pipe 12 and sprayed out from the nozzle 13, so that the water can be sprayed into the crushing frame, so that the dust generated during the crushing can be settled, effectively reducing the dust concentration in the air and preventing the staff from inhaling a large amount of dust and damaging their bodies. After the crushing is completed, the water pump 11 can be turned off, and the water amount in the water tank 10 can be observed through the transparent plate 21, so that the staff can add water in time.

[0031] See also Figure 6 and Figure 7 As shown, it also includes a screen 14, a rotating disk 15, a connecting shaft 16, a connecting rod 17, a sliding plate 18 and a pull rod 19. The right end of the crushing roller 4 is fixedly connected to the rotating disk 15, and the two rotating disks 15 are located on the right side of the spur gear set 5. The right side of the rotating disk 15 is fixedly connected to the connecting shaft 16, and the two connecting shafts 16 are located on the same horizontal line. Connecting rods 17 are slidably arranged on the two connecting shafts 16, and the lower part of the connecting rod 17 is fixedly connected to the screen 14. The screen 14 is located in the support frame 1 and is located below the two crushing rollers 4. The middle part of the support frame 1 is symmetrically slidably arranged with sliding plates 18. The two sliding plates 18 are located in front of the filter, and a pull rod 19 is arranged on the sliding plate 18 by welding.

[0032] See also Figure 6 As shown, a protective sleeve 20 is also included, and the pull rod 19 is covered with the protective sleeve 20.

[0033] When the crushing roller 4 rotates, the crushing roller 4 drives the rotating disk 15 and the connecting shaft 16 to rotate. When the connecting shaft 16 rotates, it drives the connecting rod 17 and the screen 14 to move up and down, so that the crushed stone fragments can be screened. After the crushing is completed, the servo motor 3 is turned off, and the pull rod 19 is used to open the sliding plate 18, and then the unqualified stones on the screen 14 are collected. After the collection is completed, the sliding plate 18 is closed, and the unqualified stones are poured back into the crushing frame 2, and the servo motor 3 is started again to perform secondary crushing to ensure that the stones are crushed to a suitable size. After the crushing is completed, the servo motor 3 can be turned off. The protective cover 20 increases the friction between the staff's hands and the pull rod 19, which is convenient for the staff to pull the pull rod 19 better.

[0034] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments may be designed without departing from the scope of the present invention. Therefore, the scope of the present invention should be limited only by the appended claims.
