Description
Technical Field
[0001] The utility model relates to the technical field related to conveying devices, in particular to a conveying device for producing biological organic fertilizers. Background Art
[0002] Bio-organic fertilizer refers to a type of fertilizer that has the effects of both microbial fertilizer and organic fertilizer, which is made by combining specific functional microorganisms with organic materials that are mainly derived from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and have been harmlessly treated and decomposed. Nowadays, bio-organic fertilizers require the transportation of fertilizer raw materials during the production and processing process, so a conveying device is needed.
[0003] The utility model patent with announcement number CN221586989U discloses a conveying device for the production of biological organic fertilizers, which belongs to the technical field related to conveying devices. It solves the problem in the existing technology that in the process of conveying fertilizer raw materials, since the fertilizer raw materials need to be fermented during the production and processing process, the water content inside them is mostly high, which makes the fertilizer raw materials easily adhere to the conveyor belt on the conveyor during transportation. In order to avoid the raw materials adhered to the conveyor belt affecting the operation of the conveyor, the staff needs to clean the surface of the conveyor belt regularly. However, this not only greatly increases the workload of the staff, but also has a slow cleaning efficiency, which easily affects the working efficiency of the conveyor. The invention comprises: a frame, a conveyor belt is provided on the frame, and a cleaning mechanism for cleaning the surface of the conveyor belt is provided at the bottom of the frame. The cleaning mechanism is a shell, and the shell is provided at the bottom of the frame. A collection mechanism for collecting waste cleaned from the surface of the conveyor belt is provided inside the shell, and the collection mechanism includes a collecting member and a mounting frame. When the utility model is in use, the scraper and the cleaning brush are installed inside the shell, so that the scraper and the cleaning brush can clean the fertilizer raw materials attached to the surface of the conveyor belt, thereby preventing the adhesion of the raw materials from affecting the operation of the conveying device and the service life of the conveyor belt, reducing the workload of the staff and improving the practicality of the conveying device. The cleaned raw materials can be collected by installing the collecting piece and the storage box, which is convenient for subsequent staff to recycle them.
