[0002] Concrete crusher, also known as jaw crusher, is suitable for metallurgy, mining, construction, chemical industry, water conservancy and railway departments. It is used for fine and medium crushing of various ores and rocks with compressive strength below 250Mpa. It has the characteristics of large crushing ratio, uniform finished product particle size, low power consumption and convenient maintenance.

[0003] When crushing concrete bricks, in order to reuse the concrete bricks, the concrete bricks are crushed to separate the stones and sand in the concrete bricks, so that the sand and stones in the concrete bricks can be reused separately. In the prior art, most of them directly crush the concrete and then separate the stones and sand. However, due to the presence of stones, it is difficult for the crusher to separate the sand into fine gravel, so the sand needs to be crushed again and then reused. However, this method increases the operating procedures, and it is necessary to separate the sand and stones separately, and then refine the sand, which is cumbersome. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a concrete brick crushing and recycling device, which can separate the test blocks and sand blocks of concrete bricks and then refine the sand blocks to solve the problems raised by the above background technology.

[0015] The utility model has a simple structure and a reasonable design. Firstly, the concrete bricks are preliminarily crushed by the first crushing mechanism, and the sand and gravel are divided into small particles. Since the stone has a large hardness, it will generate a reaction force on the crushing roller, so that the distance between the two crushing rollers is increased. After the preliminary crushing is completed, the stone and sand reach the dividing screen. Since the particles of the gravel are small, the gravel passes through the dividing screen to reach the second crushing mechanism. The second crushing mechanism further refines the gravel. While completing the separation of sand and stone, the sand blocks can be further refined, thereby improving the utilization rate of the concrete bricks. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1-4 As shown, a concrete brick crushing and recycling device includes a box body 1, a feed inlet 11 is provided on the top of the box body, a first crushing mechanism 2 is provided below the feed inlet 11 in the box body 1, downwardly inclined dividing screens 12 are provided below the two first crushing mechanisms 2, a first outlet 13 is provided on one side of the dividing screen 12 of the box body 1, a baffle plate 14 is slidably connected to the box body 1 on one side of the first outlet 13, a second crushing mechanism 3 is provided directly below the dividing screen 12 in the box body 1, a material receiving frame 15 is provided in the box body 1 directly below the second crushing mechanism 3, and a second outlet 16 is provided on the front side of the material receiving frame 15 of the box body 1.

[0028] By adopting the technical solution of this embodiment, concrete bricks enter the box body 1 from the feed port 11, and are initially crushed by the first crushing mechanism 2. After the crushing is completed, the concrete bricks are divided into smaller particles, and then screened by the dividing screen 12. The small sand and gravel pass through the dividing screen 12 and reach the second crushing mechanism 3. The large stones are located below the dividing screen 12. Due to the action of gravity, the large sand and gravel reach the first outlet 13. When the baffle plate 14 is pulled out, the large sand and gravel are discharged from the first outlet 13. The small sand and gravel are crushed by the second crushing mechanism 3 and then reach the receiving frame 15. After the crushing is completed, the receiving frame 15 is pulled out from the second outlet 16.

[0029] Reference Figure 1-2 and Figure 3 The first crushing mechanism 2 includes two crushing rollers 201 and a first motor 202. The two crushing rollers 201 are assembled and connected to the box body 1. The output shaft of the first motor 202 is transmission-connected to one crushing roller 201. Both ends of the other crushing roller 201 are assembled and connected with an elastic adjustment mechanism 21 for adjusting the distance between the two crushing rollers 201.

[0030] In this embodiment, the first motor 202 drives a crushing roller 201 to rotate, and the elastic adjustment mechanism 21 is used to adjust the distance between the two crushing rollers 201 according to the crushing situation.

[0031] Reference Figure 1-2 and Figure 4 The second crushing mechanism 3 includes two grinding rollers 301, a second motor 302 and two gears 303. The two grinding rollers 301 are assembled and connected with the box body 1. The output shaft of the second motor 302 is transmission-connected with the grinding rollers 301. The two grinding rollers 301 are meshed and transmitted through the gears 303.

[0032] In this embodiment, the second motor 302 drives the grinding rollers 301 to rotate. When one grinding roller 301 rotates, due to the mutual meshing of the gears 303, the two grinding rollers 301 rotate inwards relative to each other at the same time to crush the sand and gravel.

[0033] Reference Figure 3 The elastic adjustment mechanism 21 includes a ring 211, a baffle 212, a spring 213, a telescopic rod 214 and a positioning seat 215. The ring 211 is rotatably connected to the end shaft of the crushing roller 201. A flat cut is provided on one side of the ring 211. A straight slot is provided on the housing 1. The end shaft of the crushing roller 201 slides in the straight slot. The positioning seat 215 is fixedly connected to the housing 1. The spring 213 and the telescopic rod 214 are assembled and connected between the positioning seat 215 and the baffle 212. The baffle 212 abuts against the flat cut of the ring 211.

[0034] In this embodiment, when the crushing roller 201 is subjected to a large force, the distance between the two crushing rollers 201 tends to increase, and the flat cutout of the ring 211 will squeeze the blocking plate 212, so that the spring 213 will be compressed and the distance between the two crushing rollers 201 will increase. It should be noted that when the spring 213 is deformed, the force exerted on the spring 213 is greater than the force of the crushing roller 201 to crush the sand and gravel.

[0035] Reference Figure 4 : Two grinding rollers 301 are located on one side of the box body 1, and a material guide plate 304 inclined toward one side of the grinding rollers 301 is fixedly connected to the other side of the box body 1, and the material guide plate 304 is located on the upper side of the grinding rollers 301.

[0036] In this embodiment, the guide plate 304 is used to prevent the crushed sand and gravel from falling directly into the receiving frame 15 without passing through the grinding roller 301 .

[0037] Reference Figure 2 A U-shaped plate 131 with a U-shaped opening facing the box body 1 is fixedly connected above the first outlet 13 of the box body 1, and the blocking plate 14 is slidably connected to the U-shaped plate 131.

[0038] In this embodiment, the U-shaped plate 131 is used to insert the material blocking plate 14 and prevent the material blocking plate 14 from sliding.

[0039] Reference Figure 4 A plurality of circular holes are evenly and vertically formed in the middle of the baffle plate 14 , and a positioning pin 141 is connected between the circular holes of the baffle plate 14 and the box body 1 .

[0040] In this embodiment, when the position of the material blocking plate 14 is adjusted upward, the positioning pin 141 is used to fix the position of the material blocking plate 14 .

[0041] Reference Figure 1-2 : The housing 1 is provided with a protective shell 3031 outside the gear 303.

[0042] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
