Description

Technical Field

[0001] This utility model relates to the technical field of impact crushers, specifically a reversible impact crusher circulating crushing mechanism. Background Technology

[0002] Reversible impact crushers are generally used as secondary crushing equipment. Due to their large crushing ratio and high output, they are widely used in fields with high requirements for stone shape, such as highways, reservoirs, railways, and airports.

[0003] The existing reversible impact crusher mainly uses tie rods and springs to connect the impact plates. This method cannot be used to crush materials at the same frequency as the high-speed rotating hammer. The efficiency of crushing materials by simply throwing them with the hammer and using the impact plates is low, making it difficult to improve the efficient crushing of large-volume materials.

[0004] In view of this, a reversible impact crusher circulating crushing mechanism was designed to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows:

[0007] A reversible impact crusher circulating crushing mechanism includes a machine body shell, two support plates installed at the bottom of the inner cavity of the machine body shell, a hammer mechanism installed in the two support plates, and a material impact mechanism installed in the machine body shell. The hammer mechanism includes a motor and a main shaft. A gear is fixedly installed on the transmission shaft inside the motor. A load-bearing roller is fixedly installed on the outside of the main shaft. Multiple evenly distributed hammers are clamped to the outside of the load-bearing roller. Two symmetrically distributed eccentric gear disks are installed at both ends of the main shaft. Traction rods are movably connected to the eccentric gear disks, and there are two traction rods. The material impact mechanism includes four track plates fixedly installed on the inner wall of the machine body shell. The track plates have slides inside, and an impact plate is set between two adjacent track plates. A column is installed in the middle of the impact plate. Two slides are inserted into both ends of the impact plate, and the rectangular plate segments of the slides are movably installed in the slides.

[0008] In a preferred embodiment, the present invention can be further configured such that: both ends of the load-bearing roller are provided with U-shaped grooves, and two symmetrically distributed reinforcing bolts are threaded into the U-shaped grooves; the hammer plate is installed in two of the U-shaped grooves by means of the reinforcing bolts.

[0009] In a preferred embodiment, the present invention can be further configured such that the inclined surface on the inner side of the hammer plate is adapted to be parallel to the inclined surface on the inner side of the counterattack plate.

[0010] In a preferred embodiment, the present invention can be further configured such that: two studs are fixedly installed at the outer end of the track plate, and nuts are installed on the external threads of the studs.

[0011] In a preferred embodiment, the present invention can be further configured such that: a limiting rod is installed in the middle of the inner side of the slide rail, a spring is provided on the outside of the limiting rod, and the limiting rod is adapted to penetrate into the rectangular plate segment of the slide frame.

[0012] In a preferred embodiment, the present invention can be further configured such that: the two ends of the counter-attack plate are provided with rectangular grooves facing the end face of the track plate, and the inner end of the track plate is adapted to fit into the rectangular groove.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. This utility model involves installing a hammer at an angle parallel to the inclined surface of the impact plate on the outside of the existing main shaft and load-bearing roller.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0026] The following describes, with reference to the accompanying drawings, some embodiments of a reversible impact crusher circulating crushing mechanism provided by this utility model.

[0027] Example 1:

[0028] Combination Figures 1 to 4 As shown, the present invention provides a reversible impact crusher circulating crushing mechanism, including a machine body shell 100, two support plates 400 installed at the bottom of the inner cavity of the machine body shell 100, a hammer mechanism 200 installed in the two support plates 400, and a material impact mechanism 300 installed in the machine body shell 100. The hammer mechanism 200 is used to actively crush the material fed into the machine body shell 100, and the two sets of material impact mechanisms 300 are used to impact crush the material that has passed through the hammer mechanism 200 and is thrown outward.

[0029] The hammering mechanism 200 includes a motor 260 and a main shaft 210. A gear 2601 is fixedly installed on the transmission shaft inside the motor 260. A load-bearing roller 220 is fixedly installed on the outside of the main shaft 210. Multiple evenly distributed hammers 230 are snapped onto the outside of the load-bearing roller 220. Two symmetrically distributed eccentric gear disks 240 are installed at both ends of the main shaft 210. Traction rods 250 are movably connected to the eccentric gear disks 240, and there are two traction rods 250.

[0030] The material counterattack mechanism 300 includes four track plates 310 fixedly installed on the inner wall of the outer shell 100. The track plates 310 have slide rails 3101 inside, and a counterattack plate 350 is provided between two adjacent track plates 310. A column 360 is installed in the middle of the counterattack plate 350, and two slides 340 are inserted into both ends of the counterattack plate 350. The rectangular plate segment of the slide 340 is movably installed in the slide rail 3101.

[0031] The counter-attack plate 350 has rectangular grooves on its end faces facing the track plate 310 at both ends, and the inner end of the track plate 310 is adapted to fit into the rectangular groove.

[0032] In use, the motor 260 is started via an external control cabinet. As the motor 260 runs, its internal transmission shaft, in conjunction with gear 2601, drives one of the eccentric gear discs 240 to rotate. Then, the material is introduced from the feed port of the outer casing 100. At this time, the high-speed rotating load-bearing roller 220 and multiple hammers 230 actively crush the introduced material. As the multiple hammers 230 throw the crushed material outward, the thrown material is projected toward the two impact plates 350. When the two eccentric gear discs 240 drive the two traction rods 250 to move centrifugally, the two impact plates 350 vibrate at high frequency around the load-bearing roller 220 as the axis.

[0033] With the high-frequency vibration of the two impact plates 350, the material after being thrown will be subjected to the impact force the moment it comes into contact with the inner wall of the two impact plates 350, thereby achieving the purpose of secondary crushing.

[0034] Example 2:

[0035] Combination Figure 2 and Figure 3 As shown, based on Embodiment 1, both ends of the load-bearing roller 220 are provided with U-shaped grooves, and two symmetrically distributed reinforcing bolts 2301 are threaded in the U-shaped grooves. The hammer 230 is installed in two of the U-shaped grooves by means of the reinforcing bolts 2301.

[0036] The inclined surface on the inner side of the hammer 230 is adapted to be parallel to the inclined surface on the inner side of the counterattack plate 350.

[0037] Preferably, by directly opening multiple evenly distributed U-shaped grooves at both ends of the load-bearing roller 220, when the hammer 230 needs to be replaced, the damaged hammer 230 can be quickly replaced simply by using the reinforcing bolt 2301. At the same time, the groove on the inner side of the replaced hammer 230 can be adapted to be parallel to the inclined surface of the inner wall of the impact plate 350 without calibration, ensuring that after the material is thrown by the hammer 230, the material can be accurately impacted by the inclined surface of the inner wall of the impact plate 350.

[0038] Example 3:

[0039] Combination Figure 4 As shown, in the above embodiment, two studs 3102 are fixedly installed on the outer end of the track plate 310, and nuts are installed on the external threads of the studs 3102;

[0040] A limit rod 320 is installed in the middle of the inner side of the slide rail 3101. A spring 330 is provided on the outside of the limit rod 320. The limit rod 320 is adapted to pass through the rectangular plate segment of the slide 340.

[0041] Preferably, the two studs 3102 at the outer end of the track plate 310 are pre-inserted into the holes in the inner wall of the housing 100, and are assembled by using nuts along the threaded section of the studs 3102 after they pass through the holes in the inner wall of the housing 100, and the nuts are tightened by using an electric wrench until the four evenly distributed track plates 310 can provide sufficient stable support for the two counter-attack plates 350.

[0042] The working principle and usage process of this utility model are as follows: The rod segments at both ends of the main shaft 210 are pre-installed in the support plate 400 using two bearings, and the motor 260 is fixedly installed in the outer shell 100 of the machine body.

[0043] As the motor 260 starts and runs, the transmission shaft inside the motor 260, in conjunction with the gear 2601, will drive one of the eccentric gear disks 240. Since the two eccentric gear disks 240 are respectively installed at both ends of the main shaft 210, the main shaft 210 and the load-bearing roller 220, which are movably installed in the support plate 400, will drive the evenly distributed multiple hammers 230 to rotate at high speed.

[0044] Meanwhile, two traction rods 250, which are mounted on the outer surface of the two eccentric gear discs 240, drive the two columns 360 and the impact plate 350 to vibrate regularly. The two impact plates 350 vibrate at the same frequency. Then, the material is introduced from the feed port of the outer casing 100. The high-speed rotating load-bearing roller 220 and multiple hammers 230 reverse the material until it is crushed by impact. The material thrown outward along the hammers 230 is impacted by the two vibrating impact plates 350. The material after the double impact can be effectively crushed, further enhancing the material crushing efficiency.

[0045] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
