Description

  The present invention relates to a simulation apparatus that enables selection of an appropriate agricultural working machine such as a tractor or a rice transplanter.

  In recent years, mechanization of farm work has made it possible to increase the yield and quality of crops by shortening working hours and releasing heavy labor, as well as performing timely work and improving work accuracy.

  However, agricultural machinery such as tractors, rice transplanters, and combine machines are restricted in terms of their use period not only by the seasonality of crop production and weather conditions, but also by the form of local agriculture and the appropriate growth period of crops. Therefore, in order to use agricultural machines efficiently and economically, it is necessary to grasp how much work performance the introduced agricultural machines can exhibit within a restricted period. .

Therefore, conventionally, the theoretical work amount obtained from the work width and work speed of the farm work machine is corrected by the field work efficiency, which is the ratio of the theoretical work amount and the field work quantity, so that the field per hour of the farm work machine is corrected. Calculate the amount of work, and multiply the calculated field work amount per hour by the actual work time per day obtained by correcting the work time per day with the actual work rate. It is considered to grasp the work efficiency of the agricultural machine by calculating the amount of field work per day. Also, by entering numerical values such as the working width, working speed, field work efficiency, daily work time, actual work rate, etc. of the farm machine in a predetermined input field, A calculation program configured to automatically calculate the field work amount per day and the like is also distributed on the Internet (see, for example, Non-Patent Document 1).
