Description

Technical Field

[0001] The utility model belongs to the technical field of biomass collection devices, and in particular relates to a crop biomass collection device with a weighing function. Background Art

[0002] Biomass is an ecological term that refers to the dry weight of a substance in a certain unit area. Dry weight refers to the weight of a substance after it is completely dried. It is used to describe the weight of an organism or its tissue after removing water. In biology, it can also be said that dry weight refers to the weight of a cell after all water is removed. Dry weight is usually measured after drying at a temperature of 80°C or below for a period of time.

[0003] Generally, material drying weighing is carried out in an open environment. The material is placed on a mechanical weighing device, and the mechanical weighing device is used to measure the weight reduction of the material per unit time during the evaporation process. Finally, the material drying weighing curve is obtained by recording the result of material drying weighing. The accuracy and precision of material drying weighing are greatly affected by the mechanical weighing device, especially the offset of the weighing moving rod in the mechanical device, which can easily lead to errors or low accuracy in the material drying weighing data.

The positioning groove 111 positions the second guide block 12 through the protrusion 121, and the other side of the second guide block 12 contacts the outer wall of the regular hexagonal column 10.

[0053] In addition, a second gravity balancing ball 13 is provided at the lower end of the regular hexagonal column 10 , and the regular hexagonal column 10 is in contact with the inner side wall of the sleeve seat 11 .

[0054] The second guide block 12 contacts the outer side wall of the regular hexagonal column 10, so that the regular hexagonal column 10 moves in the vertical direction along the second guide block 12, and prevents the regular hexagonal column 10 from rotating.
