A portable load-bearing device

Abstract

The invention relates to a portable bearing device which comprises a chair surface, wherein slide paths are arranged on the lower end surface of the chair surface in parallel, positioning slots are formed in the rear ends of the slide paths, slide blocks are arranged in the slide paths, the lower end surfaces of the slide blocks are connected with supporting arms in a hinged mode, the rear end of the chair surface is connected with a rear side plate in the hinged mode, an umbrella holding frame is arranged at the rear side of the upper end of the rear side plate, the lower ends of the supporting arms are connected to the lower part of the front end surface of the rear side plate in the hinged mode, hanging strips are arranged on the front parts of the left and the right side surfaces of the chair surface, the front end of the chair surface is connected to a front side plate in the hinged mode, and hanging columns are arranged on the left and the right side surfaces of the front side plate. The portable bearing device disclosed by the invention can be used for quickly compressing the size of a rice seedling pulling stool, so that the rice seedling pulling stool occupies a small space and can provide convenience in carrying; a pressing handle is used for pressing a pressure spring to eliminate supporting force of the pressure spring on a supporting rod; meanwhile, the slide blocks correspondingly move into the slide paths respectively by utilizing downward component force of the handle to facilitate folding of the rear side plate; and the umbrella holding frame on the rear side plate can be used for replacing manpower to hold a sunshade.

Description

technical field [0001] The invention relates to the field of agricultural labor supplies, in particular to a portable load-bearing device. Background technique [0002] Chairs are one of the most important items in people's lives. From seats in vehicles, to seats in homes, to seats in labor tools, the forms of seats are ever-changing, and the scope of application is very wide. They are ubiquitous. in people's lives. [0003] There are a large number of terraced fields distributed in the hilly areas of southeastern my country. Terraced fields are generally reclaimed on hills with a slope of less than 30° to meet the needs of small arable areas in some areas of our country. However, it is difficult to popularize modern agricultural machinery in terraced fields. [0004] People who plant rice in the terraced fields need to cultivate rice seedlings in the terraced fields first. When the rice seedlings are to be transplanted, they must first pull out the rice seedlings, bundle t...

Problems solved by technology

When pulling seedlings, in order to prevent people from working for a long time, people usually sit on a "stool". The "stool" is generally divided into two types. One is to nail a small wooden board to a log , the other end of the log is sharpened. When using it, insert the sharpened end of the log into the seedling field and sit on a small wooden board. Because this kind of seedling pulling stool is supported by a single leg, although it is simple to make and easy to carry, it is not easy to control It is often easy to fall over; the other is to set several legs between two wooden boards. When in use, you can sit on any wooden board, and the other board is used as the bottom board to be immersed in water to delay the sinking of the "stool". The area of ​​the wooden board under this kind of seedling-pulling stool is too small, which is easy to make the "stool" sink quickly; Hard
