Description

Technical Field

[0001] The utility model relates to the technical field of push-pull carts, and more specifically, to a push-pull cart used for assisting in picking corn cobs in agriculture. Background Art

[0002] Agriculture is an industry that utilizes the growth and development laws of animals and plants to obtain products through artificial cultivation. Agriculture belongs to the primary industry. The objects of agricultural labor are living animals and plants, and the products obtained are the animals and plants themselves. Agriculture is a basic industry that provides support for national economic construction and development. It is an industry that produces food and industrial raw materials by cultivating animal and plant products. Corn is an annual monoecious cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop, and also the crop with the highest total output in the world. Its planting area and total output are second only to rice and wheat. Small areas of corn fields cannot use machinery, and corn cobs can only be picked manually.

[0003] The prior art developed a push-pull cart with the publication number CN215002547U for assisting in picking corn cobs in agriculture. By setting a large support plate, a large rotating shaft, rollers, a first large connecting rod, a second large connecting rod, a large U-shaped push-pull rod, a large movable plate, a large guide rod, a first connecting plate and other structures, it can be easily adjusted and the bag can be easily opened and hung. People do not need to hold the bag for a long time, which will not cause hand pain, so it is convenient for people to put corn cobs into the bag, and the bag with corn cobs can be conveniently transported.
