Foldable trolley for experimental field

Abstract

The invention provides a foldable trolley for a test field. The foldable trolley comprises a trolley hopper, a trolley frame, trolley handles and a folding mechanism. The two sides of the front end of the trolley hopper are each provided with an insertion rod. The two sides of the front end of the trolley frame are each provided with a hook. The trolley hopper is arranged on the upper portion of the trolley frame. The insertion rods are arranged in the hooks in a sleeved mode. The two sides of the rear end of the trolley frame are each provided with two opposite connection flat plates. The head end of each trolley handle is arranged between the two corresponding connection flat plates in a hinged mode. A movable door which can be opened at any time is arranged on a bottom plate of the trolley hopper. The inner sides of two cross beams of the trolley frame are each provided with a sliding groove. Openings of the two sliding grooves are opposite. The front ends of the two cross beams of the trolley frame are each provided with a limiting groove. The folding mechanism is arranged between the two cross beams and located under the movable door. The foldable trolley is simple in structure and convenient to operate; the folding mechanism can be folded in the trolley hopper, and the trolley handles can be folded to the two sides of the trolley hopper, so that the occupied space of the foldable trolley is greatly reduced, and convenience is provided for carrying the foldable trolley in a car trunk.

Description

technical field [0001] The invention relates to a small trolley, in particular to a foldable small trolley which can be used in a test field. Background technique [0002] The wheelbarrow is widely used in field work because of its large load capacity, convenient operation and good passing performance in the field. In some crop test fields, the wheelbarrow is often used to transport in the test field Some test samples or some specific test fertilizers. In some areas, because the crop research institutions are far away from the crop test fields, the staff generally need to drive to the crop test fields. There are no trolleys available, and the staff can only use buckets or baskets to carry the research and development fertilizer or seeds, which makes the staff's work intensity higher and work efficiency is not high. Contents of the invention [0003] The purpose of the present invention is to provide a collapsible trolley for a test field. The wheels, handles and outrigge...

Problems solved by technology

In some areas, because the crop research institutions are far away from the crop test fields, the staff generally need to drive to the crop test fields. There are no small carts available, and the staff can only use buckets or baskets to carry the research and development fertilizer or seeds, which makes the staff work more intensive and less efficient
