Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a crushing protection device. Background Art

[0002] In the process of mining mineral resources, large blocks of stone such as limestone are directly provided to the coarse crushing workshop as raw materials for crushing. At present, when the crusher is crushing the stone, the stone is subjected to the force of the crushing roller, which can easily cause the stone to splash out from the feed port and cause harm to the construction workers. Therefore, it is necessary to set a protective device at the feed port of the crusher.

[0003] For example, the Chinese patent No. 202322137805.8 discloses a crusher with a protective structure, including a shell and a driving motor, a feed port is installed on the top of the shell, a discharge port is installed in the middle position of the bottom of the shell, support frames are installed on both sides of the bottom of the shell, a crushing roller is installed inside the shell, and the driving motor is connected to one side of the crushing roller; a servo motor is installed on the top of the shell through a protective shell, a first connecting rod is connected to the bottom of the servo motor through a driving shaft, one side of the first connecting rod is connected to the second connecting rod through a rotating shaft, and the side of the second connecting rod away from the first connecting rod is connected to a baffle through a rotating shaft, sliders are installed on both sides of the baffle, and two groups of sliders are installed symmetrically about the center line of the baffle, and the baffle forms a sliding structure between the slider and the slide groove of the shell.

[0004] Most of the existing shielding devices are provided with baffles, so that when the stone is crushed, the baffles are driven to slide and cover the feed port to prevent the stone from splashing out of the feed port. However, this method requires additional repeated driving of the baffles to open or cover the feed port when adding materials, which is troublesome to operate and reduces the efficiency of crushing the stone. Therefore, in view of the above technical problems, a crushing shielding device is proposed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model proposes a crushing and protecting device, which does not require additional driving of the baffle to move repeatedly when adding materials, is easy to operate, and improves the efficiency of crushing stones.

[0006] The crushing protection device comprises a crusher feed port and a protection mechanism, wherein the protection mechanism comprises:

[0007] Mounting rods, both long sides of the crusher feed port are provided with receiving grooves, and the mounting rods are arranged in the two groups of receiving grooves;

[0008] A mounting seat, the bottom ends of the two groups of mounting rods on opposite sides are provided with mounting grooves, the two groups of mounting grooves are provided with connecting shafts along the length direction of the crusher feed port, the two groups of connecting shafts are sleeved with the mounting seat, the mounting seats are sequentially provided with multiple groups along the length direction of the crusher feed port, the tops of the multiple groups of mounting seats are provided with tension springs, the top surfaces of the mounting grooves are provided with yielding grooves, the tops of the tension springs are connected to the top surfaces of the yielding grooves, so that the tops of the mounting seats abut against the top surfaces of the mounting grooves; and

[0010] The beneficial effects of the above-mentioned crushing protection device are:

[0011] When adding materials, stones fall on multiple groups of baffles. At this time, the baffles rotate downward due to the influence of the gravity of the stones, and the tension springs are stretched and lengthened. The baffles rotate downward to open the crusher feed port, so that the stones fall into the crusher for crushing. After the stones fall into the crusher, the gravity on the baffles disappears, and the reaction force of the tension springs causes the baffles to rotate upward and reset to cover the crusher feed port, thereby preventing the stones from splashing out of the feed port. When adding materials, there is no need to additionally drive the baffles to move repeatedly, which is easy to operate and improves the efficiency of crushing stones. The baffles that are not affected by the gravity of the stones remain stationary, thereby effectively preventing the stones from splashing out of the crusher feed port when adding materials, thereby improving the protection effect of the device.

[0012] In one embodiment, the mounting seat is provided with a plug-in slot, the top surface of the plug-in slot is provided with a through spring clip slot, one end of the baffle can be inserted into the plug-in slot, the end of the baffle inserted into the plug-in slot is provided with a spring clip buckle, and the spring clip buckle can be clamped in the spring clip slot. The baffle can be removed from the mounting seat by applying an external force to the spring clip buckle to deform the spring clip buckle and withdraw it from the spring clip slot, which makes it convenient to install and remove the baffle, and it is convenient to replace the baffle separately when the baffle is damaged, thereby reducing the use cost of the device.

[0013] In one embodiment, a rubber pad is provided on the bottom surface of the baffle, and the rubber pad is bonded to the baffle. The rubber pad can prevent stones from splashing and directly hitting the baffle, thereby increasing the service life of the baffle.

By adjusting the rotating assembly to drive the two groups of mounting rods to rotate in opposite directions, the two groups of mounting rods can drive the multiple groups of baffles to rotate downward into the two groups of receiving grooves through the multiple groups of mounting seats, and at this time, the multiple groups of baffles can cancel the shielding of the crusher feed port, thereby facilitating the cleaning and maintenance of the crusher through the crusher feed port.

[0015] In one embodiment, the rotating assembly includes a transmission shaft, a worm and a worm wheel; both ends of the two groups of mounting rods are provided with a rotating shaft, the rotating shaft is rotatably arranged on the end wall of the receiving groove, the two groups of rotating shafts at one end of the mounting rods are provided with the worm wheel, the transmission shaft is rotatably arranged on the feed port of the crusher, and both ends of the transmission shaft are provided with worms, the two groups of worms rotate in opposite directions, and the two groups of worms mesh with the two groups of worm wheels respectively.

When adding materials, there is no need to drive the baffles 40 to move repeatedly, which is easy to operate and improves the efficiency of crushing stones. The baffles 40 that are not affected by the gravity of the stones remain stationary, thereby effectively preventing the stones from splashing out of the crusher feed port 10 during addition of materials, thereby improving the protective effect of the device.

When adding materials, there is no need to drive the baffles 40 to move repeatedly, which is easy to operate and improves the efficiency of crushing stones. The baffles 40 that are not affected by the gravity of the stones remain stationary, thereby effectively preventing the stones from splashing out of the crusher feed port 10 during addition of materials, thereby improving the protection effect of the device.
