[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0020] like Figures 1 to 3 In the embodiment of the utility model of the efficient crushing device for iron ditch castable material shown, the efficient crushing device for iron ditch castable material includes a casing 1, a rotating main shaft 2 is installed in the casing 1, a plurality of cross-staggered striking hammers 3 are fixedly connected to the main shaft 2, a first impact plate 4 is fixedly installed in the casing 1 above the main shaft 2, a shear seat 5 is fixedly installed in the casing 1 at the bottom end of the first impact plate 4, the shear seat 5 is provided with through grooves 6 matched with the striking hammers 3 arranged in a linear array, and a curved vibrating screen 7 is installed under the main shaft 2.

[0021] Specifically, the material to be crushed is thrown into the crushing device, and the rotating main shaft 2 drives the striking hammer 3 to quickly strike the material toward the first impact plate 4. The material breaks into small particles after colliding with the first impact plate 4, and passes through the through slot 6 on the shear seat 5 and falls on the vibrating screen 7. The large particles after crushing cannot pass through the through slot 6 and are sheared and crushed by the striking hammer 3 and the shear seat 5 at the through slot 6, and fall onto the vibrating screen 7. The material particles that fall on the vibrating screen 7 will be screened out by the vibrating screen 7 to meet the requirements, and those that do not meet the requirements will continue to move with the striking hammer 3 until the crushing is completed.

[0022] In one embodiment of the present application, preferably, the striking hammer 3 is of a crank type, and its opening direction is consistent with the rotation direction of the main shaft 2, which makes it easier for the striking hammer 3 to knock the material out, and the consistency with the rotation direction of the main shaft 2 can make it easier for the striking hammer 3 to capture material particles.

[0023] In one embodiment of the present application, preferably, a second impact plate 8 is fixedly installed on the casing 1 in front of the striking hammer 3 just below the main shaft 2, and the striking hammer 3 under the main shaft 2 is in contact with the curved bottom of the vibrating screen 7, so as to scrape away large particles that cannot be screened out by the vibrating screen 7 and strike them onto the second impact plate 8, so that the large particles are split by secondary impact, and the curved vibrating screen 7 makes it easy for large particles to gather at the bottom.

[0024] In one embodiment of the present application, preferably, a lining plate 9 is fixedly connected to the first impact plate 4 and the second impact plate 8 to increase the wear resistance of the impact plates and improve the service life of the device.

[0025] In one embodiment of the present application, preferably, the shear seat 5 is in contact with the main shaft 2, and the top surface of the shear seat 5 is a concave surface to prevent large particles from falling onto the vibrating screen 7 through the gap between the shear seat 5 and the main shaft 2. The curved surface can make the particles to be crushed gather at the concave surface to facilitate shearing and crushing by the striking hammer 3.

[0026] In one embodiment of the present application, preferably, two spring seats 10 are provided on both sides below the vibrating screen 7, the spring seats 10 are fixedly connected to the outer shell 1, a spring 11 is fixedly connected to the spring seat 10, the top of the spring 11 is fixedly connected to the vibrating screen 7, and a vibration motor 12 is fixedly installed under the vibrating screen 7 to vibrate the vibrating screen 7, thereby increasing the screening efficiency and accelerating the large particles to gather to the bottom of the curved screen.

[0027] In one embodiment of the present application, preferably, a motor 13 is fixedly connected to the housing 1 , and a driving shaft of the motor 13 is fixedly connected to the main shaft 2 for driving the main shaft 2 to rotate.

[0028] In one embodiment of the present application, preferably, a feed port 14 is provided on the casing 1, and a rotating protective plate 15 is provided on the top of the casing 1 inside the feed port 14 to prevent high-speed crushed particles from flying out of the feed port 14 during crushing operation. When the filling workload is large, the material can push open the protective plate 15 and rotate it to enlarge the feed port 14.

[0029] In summary, the high-efficiency crushing device for iron ditch castable material in the above embodiment of the utility model, specifically, throws the material to be crushed into the crushing device from the feed port 14, and the rotating main shaft 2 drives the striking hammer 3 to quickly strike the material toward the first impact plate 4. The material collides with the first impact plate 4 and breaks, and the small particles pass through the through slot 6 on the shear seat 5 and fall on the vibrating screen 7. When the large particles cannot pass through the through slot 6, they gather in the concave surface of the top surface of the shear seat 2. The striking hammer 3 and the shear seat 5 work together to shear and crush the large particles, and then they fall onto the vibrating screen 7. The vibration motor 12 is started to vibrate the vibrating screen 7, and the falling particles are crushed. The material particles on the vibrating screen 7 will be screened out by the vibrating screen 7 to meet the requirements, and the particles that do not meet the requirements will gather at the bottom of the curved surface of the vibrating screen 7, and will be scraped off the vibrating screen 7 by the striking hammer 3 and hit the second impact plate 8 to break the particles again and fall back onto the vibrating screen 7 until the crushing is completed. The device uses a rotating striking hammer to hit the material onto the impact plate to crush the material, and uses the engagement of the striking hammer and the shear seat to cut the uncrushed material into pieces. The vibrating screen will screen the crushed material. The material is crushed and screened by hitting, shearing and screening. The equipment has a simple structure and higher crushing efficiency.
