The invention discloses a rolling and crushing device for producing environment-friendly bricks, relates to the technical field of environment-friendly bricks, and aims to solve the problems of multiple times of filtering, screening, rolling and crushing. The rolling and crushing device specifically comprises a box body, wherein a mounting seat is mounted at the top end of the outer wall of the box body through a bolt; a first motor is mounted on the outer wall of the top end of the mounting seat through a bolt; the bottom end of the first motor is rotatably connected with a first rotating shaft through a coupler; the first rotating shaft penetrates through the mounting seat and the box body and extends into the box body; and a mounting plate is welded at the bottom end of the first rotating shaft. According to the rolling and crushing device, raw materials are squashed, crushed, mixed and filtered through the mutual matching of the first motor, the first rotating shaft, a crushing blade, a first telescopic rod, a pressing block and a first filter screen, so that the rolling and crushing efficiency of the device is improved; and the unqualified raw materials are rolled and crushedagain by a rolling disc, and the raw materials are filtered again through the mutual matching of a second telescopic rod, a bottom plate and a second filter screen, so that the raw materials are rolled and crushed more thoroughly, and the production qualified rate of the environment-friendly bricks is improved.

The invention provides a method for preparing neodymium iron boron through regenerating a waste material containing neodymium, iron and boron. The method comprises steps of (1) preprocessing the waste material; (2) correcting the components of the waste material; (3) crushing by hydrogen; (4) preparing into powder; (5) molding under a magnetic field; and (6) vacuum sintering. The method fully uses the waste material recycled in a production process, has high recovery rate of the waste material, can produce high performance product, has a simple and controllable flow, has high operability, uses no strong acid and strong base polluting the environment, is environment-friendly and energy-saving, and has high social and economic benefits.

The invention discloses a self-propelled corn stalk harvesting and bundling integrated machine. By combining the harvester and the baler into an integrated machine and setting a redundant device, the corn stalk harvested by the harvester is pre-stored in the redundant device, and then Stable feeding to the baler through the redundant device ensures continuous feeding of the baler during the harvesting process, and the throughput of the harvester and the baler is adjusted through the redundant device, avoiding the mismatch of throughput The problem is to improve the efficiency of harvesting and bundling corn stalks. By setting up a trigger mechanism for storing materials, the baler will only start bundling when a certain amount of corn stalks are stored in the storage tank, so as to avoid failure of the harvester or stop harvesting. , The feeding of the baler is unstable, which improves the baling effect. The corn stalks are further crushed by setting an auxiliary crushing mechanism, and the corn stalks are compressed by a pre-compression mechanism to approximate the compression ratio, further improving the baling effect.

The invention discloses a feed crushing and classified collection device. A feeding mechanism comprises a feeding channel. One end of the feeding channel is connected with a feeding port, and the other end of the feeding channel is horizontally provided with a feeding baffle. One end of the feeding baffle is hinged to the side wall of a box body, and the other end of the feeding baffle is erected on a primary regulating wheel. A crushing mechanism comprises a crushing box. The crushing box is connected to the eccentric position of a rotary table through connection rods, the axis of the rotary table is rotationally connected to a support plate through a rotating shaft, a crushing drive motor drives a crushing frame inside the crushing box, and the bottom of the crushing box is provided with primary sieve holes. A sieving mechanism comprises a primary sieve net and a secondary sieve net which are horizontally arranged, one end of the primary sieve net is hinged to the side wall of a box body, the other end of the primary sieve net is arranged on a secondary regulating wheel, one end of the secondary sieve net is hinged to the side wall of the box body, the other end of the secondary sieve net is erected on a tertiary regulating wheel, a primary box door is arranged at the hinged position of the primary sieve net, a secondary box door is arranged at the hinged position of the secondary sieve net, the crushing effect is good, and the classification sieving function is achieved.
