Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a feed retaining beam device for a crusher. Background Art

[0002] In cement processing, after the clinker goes through a series of processes such as calcination in a rotary kiln, the finally calcined clinker must be crushed by a crusher to crush the clinker into the particle size required by the next step. Although the crusher used for clinker has relatively loose requirements on the feed particles, the feed particles are large and the discharge particles are fine and uniform, but in the process of clinker transportation, there are still occasionally large particles that have not been thoroughly calcined in the rotary kiln. When conveying them to the crusher, the larger particles need to be blocked to avoid damage to the crusher.

[0003] Existing crushers will install a guard beam outside the feed port to block materials that are too large, but the fixed guard beam cannot adjust the opening size. If the material is stuck in the guard beam during use, it will lead to the inability to continuously convey the material and the inability to buffer the material. After entering the crusher, the granular material may impact the inside of the crusher and cause damage. Utility Model Content

[0004] The purpose of the utility model is to provide a crusher feed retaining beam device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a crusher feed beam device, comprising a crusher, a frame provided at the top of the crusher, the frame being a component with openings at the top and bottom ends, two baffles hingedly installed inside the frame, the two baffles being arranged opposite to each other, and the two baffles being inclined toward the midpoint position inside the frame.

[0006] Preferably, both ends of the frame are provided with a limiting plate, and one end of the limiting plate extends to the inside of the frame. The extended ends of the two limiting plates are provided with a pull rope, and the end of the pull rope is fixedly connected to the bottom edge of the corresponding baffle. By pulling the limiting plate outward, the pull rope drives the baffle to flip inward to adjust the gap between the two baffles, so that the beam device can achieve the effect of limiting the loading volume.

[0007] Preferably, a long groove is formed through the top of the two limit plates, and pads are provided at both ends of the bottom frames of the two limit plates. The pads lift the limit plates to ensure that the limit plates can move linearly at the predetermined position without tilting.

[0008] Preferably, a positioning screw is provided at the long groove position at the top of the pad, and a knob is threadedly connected to the outer surface of the positioning screw. When the limit plate is pulled to the predetermined position, the knob is twisted to make it descend and contact the top of the limit plate, thereby clamping the limit plate to prevent the baffle from flipping and resetting.

[0009] Preferably, two brackets are provided at the bottom ends of the two baffles, and the head ends of the two brackets are hingedly installed with connecting rods, and the head ends of the connecting rods are hingedly installed with support rods, and the connecting rods and the support rods are in an inclined state. The ends of the support rods are hingedly installed with fixing frames, and the ends of the fixing frames are fixedly installed inside the frame. The connecting rods and the support rods support the baffles so that they can block debris generated during crushing, thereby improving safety.

[0010] Preferably, a telescopic rod is commonly connected at the inclination position between the connecting rod and the support rod, and a return spring is provided on the outer surface of the telescopic rod. When the baffle is hit by a large volume of material and flips inward, the connecting rod and the support rod are folded, and the telescopic rod contracts, squeezing the return spring at the same time. Then the return spring releases the pressure, causing the baffle to return to its original position and continue to block flying debris.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The feed blocking beam device of the crusher pulls the limit plate outward to make the pull rope drive the baffle 3 to flip inward, and at the same time the connecting rod and the support rod are folded, the telescopic rod is contracted, and the reset spring is squeezed at the same time, so that the baffle is tilted inward. When the limit plate is pulled to the predetermined position, the knob is twisted to make it drop and contact the top of the limit plate, so that the pull rope is tightened to clamp the limit plate to prevent the baffle from flipping and resetting. At this time, a gap is generated between the two baffles, allowing the material to pass through the crusher normally. If the material is large in volume, it will hit the baffle, causing the baffle to flip inward, the connecting rod and the support rod are folded, the telescopic rod is contracted, and the reset spring is squeezed at the same time. Then the reset spring releases the pressure to reset the baffle, reducing the impact of large materials on the internal components of the crusher to avoid damage. During the crushing operation, the two baffles will block the debris generated during the crushing to prevent the debris from splashing and causing injury to surrounding personnel.

[0021] Specifically, a limiting plate 5 is provided at both ends of the frame 2, and one end of the limiting plate 5 extends to the inside of the frame 2. A pull rope 9 is provided at the extended end of the two limiting plates 5. The end of the pull rope 9 is fixedly connected to the bottom edge of the corresponding baffle 3. By pulling the limiting plate 5 outward, the pull rope 9 drives the baffle 3 to flip inward to adjust the gap between the two baffles 3, so that the beam device can achieve the effect of limiting the loading volume.

[0022] Furthermore, a long groove 8 is formed through the top of the two limit plates 5, and pads 4 are provided at both ends of the bottom frame 2 of the two limit plates 5. The pads 4 raise the limit plates 5 to ensure that the limit plates 5 can move linearly at the predetermined position without tilting.

[0023] Furthermore, a positioning screw 6 is provided at the position of the long groove 8 at the top of the pad 4, and a knob 7 is threadedly connected to the outer surface of the positioning screw 6. When the limit plate 5 is pulled to the predetermined position, the knob 7 is twisted to make it descend and contact the top of the limit plate 5, thereby clamping the limit plate 5 to prevent the baffle 3 from flipping and resetting.

[0024] Furthermore, two brackets 15 are provided at the bottom ends of the two baffles 3, and the head ends of the two brackets 15 are hingedly installed with a connecting rod 14, and the head ends of the connecting rod 14 are hingedly installed with a support rod 11.

[0025] Furthermore, a telescopic rod 12 is commonly connected at the inclination position between the connecting rod 14 and the support rod 11, and a return spring 13 is provided on the outer surface of the telescopic rod 12. When the baffle 3 is hit by a large volume of material and flips inward, the connecting rod 14 and the support rod 11 are folded, and the telescopic rod 12 contracts, squeezing the return spring 13 at the same time. Then the return spring 13 releases the pressure, causing the baffle 3 to return to its original position and continue to block the flying debris.

[0026] When the material is large, it will hit the baffle 3 and flip it inwards, the connecting rod 14 and the support rod 11 will be folded, the telescopic rod 12 will be contracted, and the return spring 13 will be squeezed at the same time, so that the baffle 3 is in an inward tilted state.
