[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to an automatic grain collector on a tricycle. Background Art

[0002] Agriculture is one of the basic industries of mankind, and food is an important material basis for human survival and development. In traditional agricultural production, harvesting, drying and collecting food are labor-intensive and inefficient links. This problem is particularly prominent in rural areas and among small farmers due to the lack of large-scale agricultural machinery and equipment.

[0003] The traditional way of drying grain is to spread it on the ground or on a drying rack after harvesting, and then collect it after it is dry. This method has the following problems: 1. The traditional drying method requires a lot of manpower, especially in the process of spreading and turning the grain; 2. The efficiency of collecting grain is low. The speed of collecting grain spread on the ground is slow. When the weather changes, the grain cannot be collected in time, causing it to be damaged or even scrapped.

[0004] There are some automatic grain collecting machines on the market, but most of them are expensive and have high maintenance costs, which are not suitable for small farmers and rural areas. Therefore, a simple, practical and low-cost grain collecting device is needed to effectively solve this problem. Utility Model Content

[0014] In order to effectively scoop up the grains drying on the ground by rotating the rotary collecting assembly;

[0015] As a further improvement of the above technical solution: the number of the scrapers is not less than two, and they are arranged at equal intervals around the axis of the rotating shaft.

[0016] The beneficial effect of this improvement is that the multiple scrapers can rotate driven by the rotating shaft to scoop up the grain accumulated on the ground.
