Description

[0010] As a further scheme of the present application: the side walls of the two secondary crushing boxes close to each other are fixedly provided with inclined plates, spring telescopic rods are mounted on the inclined plates, and one end of the spring telescopic rods on the same side is fixedly provided with a connecting plate, and the connecting plate is fixedly connected with a magnetic plate.

[0011] As a further scheme of the present application: the side walls of the two secondary crushing boxes close to each other are fixedly provided with inclined plates, spring telescopic rods are mounted on the inclined plates, and one end of the spring telescopic rods on the same side is fixedly provided with a connecting plate, and the connecting plate is fixedly connected with a magnetic plate.

[0012] The sleeve is movably provided with a piston plate, the piston plate is connected with an air inlet pipe, and a one-way valve mechanism is mounted in the air inlet pipe and the air outlet pipe; and a pressurizing mechanism is further arranged above the piston plate, for inflating and pressurizing the hollow plate.

[0014] As a further scheme of the present application: the one-way valve mechanism comprises a round hole plate provided with a round hole in the middle, the round hole plate is fixedly arranged in the air inlet pipe and the air outlet pipe, a tight rope is connected with the round hole plate, and a sealing ball is connected with one end of the tight rope.

[0015] As a further scheme of the present application: the side walls of the two crushing blocks close to each other are arrayed with crushing teeth, two crushing rollers are rotatably arranged in the secondary crushing box, and the crushing rollers are driven by an external motor.

[0016] The present application has the following beneficial effects:

[0017] (1) The present invention provides a primary crushing box and a secondary crushing box. The primary crushing box is first used to crush the solid waste, crushing the larger solid waste into smaller solid waste. The solid waste is then fed into the secondary crushing box using a blanking plate to crush the solid waste into smaller solid waste, making it easier to squeeze it into blocks. The solid waste after the initial crushing passes through the blanking plate, where the metal contained therein can be adsorbed by the magnetic plate. The automatic cleaning structure is then used to automatically clean the adsorbed metal, effectively recovering the solid waste in the solid waste, which is environmentally friendly and economical.

[0018] (2) The present invention sets a connecting rod, a pushing ball, a wedge block, a fixed rod and a first spring. When the two crushing blocks approach each other, the pushing ball pushes the wedge block to move, thereby causing the first baffle plate and the second baffle plate to descend. The second baffle plate first contacts the unloading plate to stop the solid waste from falling, thus achieving intermittent unloading and reducing the working intensity of the secondary crushing box. It also avoids excessive solid waste between the two when the first baffle plate pushes the magnetic plate to move. Subsequently, the first baffle plate pushes the magnetic plate to move, and the scraper pushes down the metal adsorbed between the two. When the two crushing blocks are reset, the first baffle plate, the second baffle plate and the magnetic plate are automatically reset, and the solid waste falls normally at this time.

[0019] (3) The present invention sets a sleeve, an air outlet pipe, a hollow plate and a pressurizing mechanism and other structures. When the solid waste is continuously falling, it contacts the force plate. With the help of the spring, the force plate drives the piston plate to move up and down continuously, thereby pressurizing the inside of the hollow plate. Due to the obstruction of the connecting plate, the scraper cannot move. When the first baffle plate completely enters the opening, the bottom end of the first baffle plate is flush with the bottom surface of the discharge plate. At this time, the scraper moves out of the hollow plate under the action of air pressure, scrapes off the metal adsorbed on the magnetic plate, and then the gas is discharged through the air outlet. Under the action of the second spring, the scraper automatically resets, and then the crushing block resets, the first baffle plate and the second baffle plate reset, and under the action of the spring telescopic rod, the connecting plate and the magnetic plate also automatically reset, which is convenient for subsequent processing. The operation of the pressurizing mechanism does not require a driving source, which is energy-saving and environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS
