On May 10, in Gaoguanzhai, Jinan, Shandong, Guanong Zhang Xueming asked friends to help design the Guapeng small train, which was already in use. The length of the car is 3.5 meters, and it can pull up to 1,000 pounds of melon. This small train is powered by a battery, which can be used for 2 hours when fully charged. The speed can be adjusted. The length of each melon shed track is 100 meters, and the cost of each small train is about 3,000 yuan.
Zhang Xueming said that this small train was designed to save labor, and one melon shed can save 6 people. When there was no small train before, it was time-consuming and laborious to manually transport the picked melons out of the greenhouse. Now the small train has been used for more than 1 month, and the effect is very good. (Editor Chi Hanyu)
