9. The automatic material spreading device for greenhouse earthworm breeding according to claim 1, characterized in that: Four support columns (15) are connected below the longer horizontal plate of the Z-shaped support plate (6); the ends of the support columns (15) are connected to a base (16); a pair of first bearing seats (18) are connected above the base (16); the inner ring of the first bearing seat (18) is fixedly connected to a first shaft rod (19); both ends of the first shaft rod (19) are connected to rollers (17); and a pair of universal wheels (13) are correspondingly connected below the shorter horizontal plate of the Z-shaped support plate (6); The upper part of the Z-shaped support plate (6) which is longer than the horizontal plate is located on the left and right sides of the first conveyor belt (5) and is connected to a gripping rod (7).

10. A heat dissipation method for an automatic material spreading device for greenhouse earthworm farming according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. The manure is introduced into the storage tank (3) through the feed pipe (2), and the second shaft (20) and the spiral blade (21) are driven to rotate by the first motor (1), so that the manure accumulated at the bottom of the storage tank (3) is conveniently transferred to a high place along the spiral blade (21) and then falls to the bottom, so as to achieve the effect of turning the manure, avoid the manure from agglomerating and affecting the subsequent manure transfer. S2. When spreading the material, hold the handle (7) and move the Z-shaped support plate (6) to the specified position, then control the opening of the electric butterfly valve (4). While the manure is transmitted to the distribution tank (9) through the first conveyor belt (5), the eight first scrapers (24) are driven to rotate clockwise by the second motor (27), so that the manure is evenly spread in the middle area between two adjacent first scrapers (24). During the clockwise scraping of the first scraper (24), the manure is accumulated on the material-facing surface of the first scraper (24). S3. At this time, the belt (32) is driven to rotate clockwise by the two first motors (31), thereby driving the second scraper (33) above the belt (32) to rotate clockwise, so as to facilitate the scraping of the manure accumulated on the facing surface of the first scraper (24) from top to bottom, and as the first scraper (24) continues to rotate, it is convenient to evenly and quickly pass the manure through the three discharge holes (23) for discharge, wherein the manure discharged from the two discharge holes (23) is respectively transmitted to the two second conveyor belts (11) through the two second guide plates (14), and is spread respectively through the two second conveyor belts (11), and the manure discharged from the last discharge hole (23) is discharged through the third conveyor belt (12) for spreading. S4. When the density of the spread material needs to be adjusted, the bidirectional screw (42) is driven to rotate by the second motor (27), so as to facilitate the two ball nut pairs (45) to move toward or away from each other. Through the connection between the gear (41) and the rack (43), the fourth shaft rods (40) on both sides are conveniently driven to rotate toward or away from each other, thereby adjusting the spread material spacing of the two second conveyor belts (11), making it convenient for the staff to adjust the spread material spacing and control the spread material density.
