The invention discloses a garden waste crushing and recovering device comprising a box body. A feeding port is formed in the upper portion of the box body, a primary crushing cavity is formed betweenthe feeding port and the box body, and a partition plate is arranged in the box body and located below the primary crushing cavity. The right end of the partition plate is fixedly connected with the box body, and the left end of the partition plate downwards inclines to form a slope. A hollow layer is arranged in the partition plate and internally provided with a heating band, a secondary crushingcavity is formed in the left end of the partition plate, and the left end of the partition plate is in smooth connection with the secondary crushing cavity. A receiving cylinder is arranged below thesecondary crushing cavity, and a three-way pipeline is arranged below the receiving cylinder. One end of the three-way pipeline is fixedly connected with the lower end of the receiving cylinder, another end of the three-way pipeline is provided with an air blower, and the third end of the three-way pipeline penetrates through the side face of the box body and extends outwards. According to the garden waste crushing and recovering device, the primary crushing cavity and the secondary crushing cavity are formed, operating resistance in the crushing process is reduced, the crushing effect is reinforced, waste can be dried in the crushing process, and the crushed waste is conveniently recovered.
