Project Description

The course project in the discipline "Design of agricultural machinery for crop production" consists of a graphic part and an explanatory note.

Explanatory note on __ s.

The graphic part includes __ sheets.

In the course design, the speed of the machine, the main design parameters of the working elements of the beet harvester were calculated; trajectory of root crops tossing on elevator is built, area of excavated soil formation is determined, energy calculation is performed.

Keywords: beet harvester, elevator, conveyor, drum, stone separator, bottom separating device, finger slide.

Introduction

The main task of designing the machine is to maximize the productivity and minimum required energy consumption for the technical process of cleaning beets from farm fields. We are faced with the task of designing a root-club harvester for harvesting beets on peat soils. Determine the dimensions of the dripping ploughshares, the parameters of the ridge. Calculate the separating part, working bodies, determine the energy parameters of the combine and the number of maintenance personnel. Draw the process diagram of the combine and determine overall dimensions.

Conclusion

The course design provides calculation of the main parameters of the root-club harvester, process flow diagrams and layout diagram of the main units. Beetroot crest parameters were calculated, the dimensions of the dripping lemechs were determined. Calculation of separating part, working members and stone separating brush device was carried out. The size of the hopper, the length of the bulkhead table and the number of necessary maintenance personnel are determined. Energy indicators of the combine are determined. The total power per VOM drive was 5828 W, the power for moving the machine was 2511 W. As a result of the calculation, based on energy indicators, the model of the tractor used in working with the designed combine was determined.
