Description

Technical Field

[0001] The utility model relates to the technical field of bar feeders, in particular to a grate structure based on bar feeders. Background Art

[0002] Grizzle feeder is a common industrial feeding equipment, which is mainly used for feeding stone in the construction industry, ore in the metal mining industry, etc. The grate structure is an important component of the grizzly feeder, and its role is to achieve the screening effect. It cooperates with the force generated by vibration to remove the dirt and fine materials on the material, thereby achieving the pre-screening function and improving the coarse crushing capacity. However, the existing grate structure for grizzly feeder still has some shortcomings. For example, when the grate structure vibrates and feeds with the overall grizzly feeder, it itself cannot vibrate with the force generated by vibration, which makes it impossible to more effectively utilize the force generated by vibration, which also leads to poor screening effect. Moreover, during screening, a large amount of dust will accumulate inside the shell. For this reason, we propose a grate structure based on a grizzly feeder. Utility Model Content

[0003] The utility model aims to provide a grate structure based on a bar feeder to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A grating structure based on a rod feeder comprises a shell, support legs are arranged around the bottom of the shell, a vibrator is arranged at the center of the bottom of the shell, a fan is arranged at the center of the left side of the shell, a vent matching the fan is arranged at the center of the left side of the shell, a blind plate is arranged on the left side of the top of the inner cavity of the shell, a hinge plate is arranged on the right side of the blind plate, a hinge is hinged between the right side of the blind plate and the left side of the hinge plate, a left connecting plate is arranged on the right side of the hinge plate, gratings are arranged laterally from inside to outside at the end of the left connecting plate away from the hinge plate, a right connecting plate is commonly connected to the right side of the gratings, and three groups of gratings are arranged from left to right and from high to low, guide blocks are arranged in the middle of the front end faces of the left connecting plate and the right connecting plate, and arc guide grooves matching the guide blocks are arranged on the front and rear end faces of the shell from left to right.

[0006] Furthermore: connecting blocks are arranged on both sides of the left and right sides of the grate bar, and bolts are arranged between the connecting blocks on the left and right sides and the left connecting plate and the right connecting plate respectively.

[0007] Furthermore: the outer walls of the guide blocks are sleeved with flexible rubber buffer sleeves, and the guide blocks are all cylindrical.

[0008] Further: the inner cavity bottom of the shell has a guide plate with the left side higher and the right side lower, a discharge port is arranged on the right side of the bottom of the shell, and the discharge port is arranged on the right side of the guide plate.

[0009] Furthermore: the arc-shaped guide grooves are arranged on the front and rear end surfaces of the shell from high to low, and the lengths of the arc-shaped guide grooves are arranged to increase from left to right.

[0010] Furthermore: a dust filter matching the vent is provided on the left side of the inner cavity of the shell.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The grate structure based on the rod feeder, when the entire shell is vibrated by the exciter, the force generated by the vibration will drive the right side of the hinged plate hinged to the blind plate to swing up and down, and when the right side of the hinged plate swings up and down, it will drive the grate to swing up and down through the left connecting plate. Similarly, the up and down swinging of the grate will also drive the next group of grate bars through the right connecting plate. In this way, the grate bars that swing up and down with the vibration can perform vibration screening more effectively, and the swing amplitude of the grate bars can be limited by the cooperation of the set guide block and the arc-shaped guide groove, so that the material will not return. A fan is set on the left side of the shell through the through hole. When the fan is working, it can continuously blow air into the shell through the vent to avoid a large amount of dust accumulating at the bottom of the inner cavity of the shell.
