Description

Technical Field

[0001] The present application relates to the field of crushed stone dividing device, and in particular to a crushed stone dividing device for mining. Background Art

[0002] The vibrating feeder commonly used in mines is generally composed of a vibrating frame, a vibrating body, a vibrating motor, a vibrator, a spring (the spring is divided into an exciting spring and a supporting spring), etc. During the production process, it can feed block and granular materials from the storage bin to the crushing device in a timely and continuous manner.

[0003] Since the discharge range of the feeder is small, the position where the stone enters the crushing device is concentrated, resulting in the accumulation of stone in some areas of the crushing device during the crushing process, which reduces the working efficiency of the crushing device and causes serious wear in some areas of the crushing device, reducing the service life of the crushing device. Prior art CN214682234U discloses a material distribution device for the feed port of a four-roll crusher, which drives the vibration rod to vibrate through a driving motor, thereby driving the feed hopper to vibrate, so that the material inside the feed hopper is more evenly stored inside the feed hopper, and then the material enters the four-roll crusher more evenly and will not accumulate in the middle, greatly improving the uniformity of the material particle size.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the above-mentioned material dividing device consumes a lot of energy in the way that the gravel in the feed hopper is evenly distributed by vibration, thereby making the cost of using the material dividing device high. Utility Model Content

[0005] In order to solve the problem that the material dividing device consumes a lot of energy in order to evenly distribute the crushed stones in the feed hopper by vibration, thereby making the cost of using the material dividing device high, the present application provides a crushed stone dividing device for mining.

[0006] The present application provides a mining crushing material dividing device, which adopts the following technical solution:

[0007] A mining crushed stone dividing device comprises a feed pipe, a dividing pipe connected to the feed pipe and a dividing assembly arranged in the dividing pipe, the dividing assembly comprises a first dividing plate and a second dividing plate rotatably connected to the inner wall of the dividing pipe, the first dividing plate is connected to a first rotation adjustment mechanism for changing the rotation angle of the first dividing plate, and the second dividing plate is connected to a second rotation adjustment mechanism for changing the rotation angle of the second dividing plate.

[0008] By adopting the above technical solution, the first rotation adjustment mechanism is used to adjust the rotation angle of the first dividing plate, and the second rotation adjustment mechanism is used to adjust the rotation angle of the second dividing plate. The stone enters the dividing pipe from the feed pipe, and the first dividing plate and the second dividing plate in the dividing pipe change the position where the stone enters the crushing device by adjusting the rotation angle. The change in the angle of the first dividing plate and the second dividing plate makes the stone evenly distributed in the crushing device, improves the working efficiency of the crushing device, and reduces the degree of wear in some areas of the crushing device. Compared with the method of evenly distributing the stone by vibration, the method of changing the angle of the first dividing plate and the second dividing plate reduces energy consumption, thereby reducing the use cost of the dividing device.

[0009] Optionally, the first rotation adjustment mechanism includes a lifting assembly connected to the material distribution pipe and a pushing assembly connected to the lifting assembly, and the pushing assembly is slidably connected to the first material distribution plate.

[0010] By adopting the above technical solution, the lifting component drives the pushing component connected thereto to perform reciprocating lifting and lowering motion, and the pushing component pushes the first dividing plate to rotate during the lifting and lowering process. When the pushing component moves toward the position where the first dividing plate is rotatably connected to the dividing tube, the pushing component increases the rotation angle of the first dividing plate, and the first dividing plate transports the stone to a position away from the center of the crushing device. When the pushing component moves toward the position where the first dividing plate is rotatably connected to the dividing tube, the pushing component decreases the rotation angle of the first dividing plate, and the first dividing plate transports the stone to a position close to the center of the crushing device.

[0011] Optionally, the lifting assembly includes a fixed plate fixedly connected to the inner wall of the material distribution pipe, a limiting slot is provided on the fixed plate, a transmission motor is connected to the fixed plate, a transmission shaft of the transmission motor is fixedly connected to a screw rod, the screw rod is arranged in the limiting slot, one end of the screw rod away from the transmission motor is rotatably connected to the fixed plate, the screw rod is connected to the pushing assembly, and the pushing assembly is slidably connected to the limiting slot.

[0012] By adopting the above technical solution, the transmission motor drives the lead screw to rotate, and the lead screw drives the pushing component to slide in the limiting groove on the fixed plate, thereby realizing the lifting and lowering of the pushing component.

[0013] Optionally, the pushing assembly includes a pushing rod threadedly connected to the screw rod, the pushing rod is slidably connected to the limiting groove, and one end of the pushing rod away from the screw rod is slidably connected to the first dividing plate.

[0014] By adopting the above technical solution, the rotation of the screw rod drives the push rod threadedly connected to it to slide in the limit groove, and the push rod drives the first dividing plate slidably connected to it to rotate, thereby adjusting the rotation angle of the first dividing plate, and then changing the position where the stone enters the crushing device.

[0015] Optionally, the push rod is rotatably connected to one end away from the screw rod with a slider, a sliding groove is provided on the first material dividing plate, the slider is slidably connected to the sliding groove, and a limiting plate is provided at the opening of the sliding groove to limit the sliding of the slider.

[0016] By adopting the above technical solution, the push rod is slidably connected to the first material dividing plate through a rotatably connected slider. During the lifting process, the push rod drives the slider to slide in the slide groove, thereby pushing the first material dividing plate to rotate, thereby realizing the angle adjustment of the first material dividing plate.

[0017] Optionally, a protective plate is provided at the rotational connection between the first material distribution plate and the inner wall of the material distribution pipe.

[0018] By adopting the above technical solution, the setting of the protective plate prevents the stone from getting stuck in the rotationally connected position between the first distribution plate and the distribution pipe when the stone enters the distribution pipe from the feed pipe, thereby preventing the stone from hindering the rotation of the first distribution plate.

[0019] Optionally, a shock absorbing assembly is provided on the side of the first material dividing plate away from the first rotation adjustment mechanism, and the shock absorbing assembly includes a shock absorbing plate, a shock absorbing spring is connected to the shock absorbing plate, a limiting telescopic rod is provided in the shock absorbing spring, and the shock absorbing spring and the limiting telescopic rod are connected to the first material dividing plate at one end away from the shock absorbing plate.

[0020] By adopting the above technical solution, the shock-absorbing plate in the shock-absorbing assembly is impacted by falling rocks, and the impact is transmitted to the first material dividing plate through the weakening of the shock-absorbing spring, thereby reducing the impact on the first material dividing plate and the first rotation adjustment structure, thereby making the first rotation adjustment assembly of the first material dividing plate less likely to be damaged.

[0021] Optionally, a reinforcing rib is provided on a side of the first dividing plate close to the first rotation adjustment mechanism.

[0022] By adopting the above technical solution, the provision of reinforcing ribs increases the strength of the first dividing plate, thereby reducing the possibility of the first dividing plate being damaged due to the impact of stones.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The stone materials are evenly distributed in the crushing device by changing the angles of the first dividing plate and the second dividing plate. Compared with the method of evenly distributing the stone materials by vibration, the energy consumption is reduced, so that the use cost of the dividing device is reduced;

[0025] 2. The setting of the protective plate prevents the stone from getting stuck at the rotational connection position between the first distribution plate and the distribution pipe when the stone enters the distribution pipe from the feed pipe, thereby preventing the stone from hindering the rotation of the first distribution plate;

[0026] 3. The shock-absorbing assembly weakens the impact of falling stones on the first dividing plate, thereby increasing the service life of the first dividing plate;

[0027] 4. The provision of the reinforcing ribs increases the strength of the first dividing plate, thereby reducing the possibility of the first dividing plate being damaged due to the impact of stones. BRIEF DESCRIPTION OF THE DRAWINGS
