The tooth transmission member includes a main gear, a slave gear and a belt. The belt is mounted on the main gear and the slave gear. The crushing rollers are grouped in two and mesh with each other. The corresponding leather tooth transmission members of the crushing rollers are rotatably connected. The screening plate is located below the crushing roller. A push plate is suspended on the upper side of the screening plate. The protruding end of the hydraulic cylinder extends into the chassis and is connected to the push plate. A brush head is installed at the bottom of the push plate, and the brush head is in conflict with the screening plate. There are multiple secondary crushing rollers placed side by side and meshing with each other. The secondary crushing rollers are connected to the power box through electric drive. The discharge port is designed in an inverted trapezoidal shape. The bottom of the discharge port is connected to the discharge box. A battery box is installed at the lower right end of the chassis.

[0008] Furthermore, a second motor is arranged on the right outer side of the discharge box, a corresponding propeller blade is arranged in the discharge box, and a discharge pipe is inserted on the left side of the bottom end of the discharge box.

[0009] Furthermore, one end of the propeller blade is connected to the second motor for electric drive.

[0010] Furthermore, the battery box is connected to the electrical components of the entire device through electrical circuits.

[0011] Furthermore, the other end of the dust removal pipe is connected to a collection box, and a suction pump is installed in the collection box.

[0012] In summary, the beneficial effects of this application are:

[0013] 1. Through the arrangement of the feed port, guide plate and crushing roller, the feed port is inserted into the top of the chassis, and the feed port is connected with the chassis. The construction waste can be directly introduced into the chassis to reduce the probability of the construction waste being blocked in the feed port. A plurality of evenly distributed guide plates are staggered on the left and right inner sides of the feed port. After the construction waste flows through the feed port, the guide plate is used to block and buffer the construction waste so that the construction waste can fall freely and smoothly into the crushing device. At the same time, orderly construction waste can be fed into the chassis in an orderly manner. Under the buffering effect of the guide plate, the crushing roller in the chassis is prevented from directly colliding with a large amount of construction waste, which effectively avoids the situation where the crushing equipment cannot be used normally and improves the service life of the crushing equipment.

[0014] Second, through the setting of screening mesh plate, push plate, secondary crushing roller and discharge box, the construction waste is initially crushed by the crushing roller and falls onto the screening mesh plate. It is filtered by its own gravity. The filter plate will block the metal objects that are not easy to crush in the construction waste. The hydraulic cylinder drives the push plate and the brush head to clean the filter plate. Under the action of the push plate, the unscreened metal is pushed to the recovery pipe, and it is exported from the chassis through the recovery pipe for the next step of processing, realizing the recovery of metal objects that are difficult to crush in the construction waste, which is beneficial to the recycling of construction waste. The secondary crushing roller is driven by the chassis to perform secondary crushing on the screened construction waste, further improving the crushing quality of the construction waste. After the secondary crushing, the construction waste falls into the discharge box through the discharge port, and the second motor drives the propeller blades to rotate forward or reverse, which can quickly output the crushed construction waste through the discharge pipe. The discharge is smooth and easy to use. When the crushing component in the chassis processes the construction waste, the dust removal pipe absorbs the produced dust, and introduces it into the collection box for unified storage, and then discharges it after purification, which improves the practical performance.
