Abstract
Description
Technical Field
[0001] This utility model relates to crushers, and more particularly to a compound crusher. Background Technology
[0002] The compound crusher is a high-efficiency, multi-functional crushing equipment. With its unique structural design and strong adaptability, it is widely used in the crushing and sand making fields.
[0003] Existing compound crushers generally consist of a frame and a crushing structure mounted on top of the frame. The crushing structure includes a cylinder fixed to the frame, a shaft rotating around a vertical axis within the cylinder, and a motor driving the shaft. The cylinder has a downward-facing discharge port and two upward-facing feed ports connected together. The top of the shaft is located between the two feed ports. Multiple layers of hammers are installed on the shaft within the cylinder, and impact plates are installed on the inner wall of the cylinder. Material falls into the cylinder through the first feed port, is struck by the high-speed rotating hammers, and, due to centrifugal force, is thrown against the inner wall of the cylinder, colliding violently with the impact plates, thus crushing the material. The crushed material exits from the discharge port.
[0004] The material exiting the discharge port still contains some large particles with only moderate crushing effect. These large particles may not meet the requirements for subsequent material use. Generally, the material exiting the discharge port needs to be screened to remove large particles, which are then collected and fed back into the crushing structure for further crushing. Existing compound crushers still have problems: they lack integrated functions for screening large particles and recycling them back into the crushing structure. The three steps of material crushing, screening large particles, and feeding large particles into the crushing structure involve different equipment, requiring manual labor or conveyor belts to move the material, resulting in a large overall space occupation and low efficiency.

[0037] Please see Figure 2 A compound crusher includes: an equipment frame 1, a crushing structure 2, a screening structure 3, and a lifting device 4.
[0038] The top of the equipment frame 1 is used for the installation of the crushing structure 2, and below the top are multiple ground-contacting support legs 1a, so that the crushing structure 2 has a suitable height between it and the ground.
[0039] Please see Figure 1 , Figure 2 and Figure 7 The crushing structure 2 is installed at the top of the equipment frame 1. Its specific composition and structure are the same as those of the existing compound crusher. It has a downward-facing first discharge port 2a and two upward-facing first feed ports 2b. The inlet positions of the two first feed ports 2b are connected together.
[0040] Please see Figure 2 , Figure 3 and Figure 4The screening structure 3 is installed on the equipment frame 1, more specifically on the support leg 1a of the equipment frame 1, so that the screening structure 3 is located below the first discharge port 2a of the crushing structure 2.
[0041] The screening structure 3 includes: a mounting part 31, multiple springs 32, a screen plate 33, a guide plate 34, and a vibrating motor 35.
[0042] The mounting section 31 is located within the equipment frame 1. More specifically, the multiple legs 1a of the equipment frame 1 are divided into two groups longitudinally, and the mounting section 31 is located between the two groups of legs 1a. The mounting section 31 may be constructed from profiles.
[0043] The screen plate 33 is fixedly connected to the mounting part 31 and has a second discharge port 33a.
[0044] The guide plate 34 is fixedly connected to the mounting part 31 and is located below the screen plate 33. It has a third discharge port 34a. That is, the material is fed in from the first feed port 2b, crushed by the crushing structure 2, and then falls from the first discharge port 2a into the screen plate 33. Normally crushed powder particles can pass through the screen plate 33 and fall into the guide plate 34, while larger particles with less effective crushing remain on the screen plate 33.
[0045] Multiple springs 32 are connected between the equipment frame 1 and the mounting part 31.
[0046] The vibrating motor 35 is fixedly connected to the mounting part 31. That is, the principle of the sieving structure 3 is the same as that of the vibrating screen. The vibrating motor 35, in conjunction with the spring 32, causes the mounting part 31, the screen plate 33, and the guide plate 34 to shake together. Correspondingly, the screen plate 33 and the guide plate 34 are tilted at a certain angle, with the side corresponding to the second discharge port 33a / third discharge port 34a being lower. With the shaking, large particles fall from the second discharge port 33a of the screen plate 33, and powder particles fall from the third discharge port 34a of the guide plate 34.
[0047] Please see Figure 3 and Figure 4 In some embodiments, the mounting portion 31 of the sieve structure 3 includes: a first portion 311 and two sets of second portions 312.
[0048] The first part 311 is used for: sliding connection with the equipment frame 1, and for fixed connection of the screen plate 33, guide plate 34, and vibrating motor 35. That is, the first part 311 is constructed using the above-mentioned method of building with profiles.
[0049] The two sets of second parts 312 are detachably connected to the two sides of the first part 311 in the longitudinal direction. More specifically, the first part 311 is composed of profiles, and there is at least one mounting profile 31a on each side of the first part 311 in the longitudinal direction. The mounting profile 31a is transverse, and at least one of its ends is unobstructed. The second part 312 and the mounting profile 31a are fixedly connected by bolts and square nuts. That is, the square nut is in the groove of the profile and is restricted from rotation. The bolt passes through the second part 312 and enters the groove to be threaded into the square nut.
[0050] The two sets of second parts 312 are also used for connecting the spring 32. More specifically, a connecting strip 1b is fixedly connected between the two legs 1a. Both the second part 312 and the connecting strip 1b have cylindrical protrusions for the ends of the spring 32 to be snapped and fixed. The upper end of the spring 32 is connected to the second part 312, and the lower end is connected to the connecting strip 1b.
[0051] With the first part 311 and the two sets of second parts 312 disconnected, the first part 311 can be pulled out / inserted into the equipment frame 1 laterally. That is, the second discharge port 33a and the third discharge port 34a are both on one side laterally, and there is no interference between the second discharge port 33a, the third discharge port 34a and the support leg 1a during the lateral movement of the first part 311. Loosen all the bolts of the second part 312, while keeping the bolts and square nuts connected. At this time, the first part 311 can be pulled out of the equipment frame 1 laterally, and the square nuts and profiles separate accordingly. Conversely, when the first part 311 can be inserted into the equipment frame 1 laterally, the square nuts need to be reinserted into the grooves of the profiles and the bolts tightened again.
[0052] The sieve structure 3 and the equipment frame 1 can be easily installed and disassembled, making it convenient to clean, maintain and repair the sieve structure 3.
[0053] Please see Figure 3 and Figure 4 In some embodiments, the first part 311 is further provided with a plurality of support feet 31b, which can be adjusted up and down. More specifically, the support feet 31b may be integrally provided with a stud, which is threadedly connected to the profile. By rotating the support feet 31b, the support feet 31b can be adjusted up and down.
[0054] During the process of laterally pulling out / inserting the device frame 1, the first part 311 can be adjusted to bring the support feet 31b to the ground, so that the first part 311 can be stably maintained at a certain height, making it easier to pull out / inserte the device frame 1 laterally. Correspondingly, after the first part 311 and the second part 312 are fixedly connected, the support feet 31b can be readjusted to lift them off the ground.
[0055] Please see Figure 2 and Figure 5 In some embodiments, the second discharge port 33a and the third discharge port 34a both extend from the same side of the equipment frame 1 in the transverse direction.
[0056] This allows for simultaneous observation of the discharge from the second discharge port 33a and the third discharge port 34a on the same side.
[0057] The lifting device 4 is located on one side of the longitudinal direction of the equipment frame 1. The lifting device 4 connects the second discharge port 33a of the screening structure 3 and the first feed port 2b of the crushing structure 2. The second discharge port 33a can be bent and extended towards the lifting device 4. The first feed port 2b and the lifting device 4 assembly can be equipped with a guide pipe 24. That is, through the lifting device 4, large particles screened by the screening structure 3 are re-input into the first feed port and crushed again by the crushing structure 2.
[0058] Please see Figure 2 and Figure 6 In some embodiments, the lifting device 4 is a Z-type bucket elevator.
[0059] The fourth inlet 4a and the fourth outlet 4b of the Z-type bucket elevator have a relatively small horizontal spacing, which makes it well-suited for this application compared to other existing lifting devices.
[0060] In some embodiments, the fourth discharge port 4b of the lifting device 4 may be connected to one of the first feed ports 2b.
[0061] Please see Figure 2 and Figure 7 In some embodiments, the guide pipe 24 between the lifting device and the first feed port 2b has a first port 24a and two second ports 24b. The first port 24a is connected to the fourth discharge port 4b of the lifting device 4, and the two second ports 24b are respectively connected to the two first feed ports 2b. That is, the fourth discharge port 4b of the lifting device 4 is simultaneously connected to the two first feed ports 2b.
[0062] Compared to the fourth discharge port 4b being connected to one of the first feed ports 2b, the fourth discharge port 4b is connected to two first feed ports 2b. Large particles screened by the screening structure 3 can be more evenly dispersed and fed into the crushing structure 2, resulting in better crushing effect.
[0063] Please see Figure 2 In some embodiments, a rectangular tube 24c is detachably connected to the inlet positions of the two first feed ports 2b. The two second ports 24b of the guide tube 24 are fixedly connected to the vertical side plate on one side of the rectangular tube 24c.
[0064] By disconnecting the rectangular tube 24c from the two first feed ports 2b, the lifting device 4 can be moved. When the rectangular tube 24c is added, the material enters the rectangular tube 24c first when it is fed from the first feed port 2b, and then is relatively evenly distributed to the two first feed ports 2b by the rectangular tube 24c.
