Tuber excavator

Abstract

The invention discloses a tuber excavator which comprises a frame body, a lifting frame is fixedly arranged on the upper side of the front portion of the frame body, a folding frame is fixedly arranged on the rear portion of the frame body, a supporting rod is arranged below the lifting frame, a gearbox assembly is arranged at the upper part of the frame body, the right side of the gearbox assembly is matched with a pressing roller assembly through a small belt pulley, the left side of the pressing roller assembly is connected with a front chain creeper at the front section through chain transmission, a lifting chain type structure is adopted for the front chain creeper, a scraper knife is fixedly arranged below the front portion of the frame body through bolts, a soil pressing roller assembly is fixedly arranged on the frame body at the upper part of the front section chain creeper, a seedling pulling roller assembly is arranged on the upper portion of the frame body, pull rod fixingplates are fixedly arranged on the two sides of the middle of the frame body respectively, the pull rod fixing plates are matched with the lifting frame of the frame body through pull rods, a limiteddeep roller assembly is arranged below the foremost portion of the frame body, and rear wheels are arranged below the rear part of the frame body; and the device has the advantages of being good in separation effect and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a stem excavator. Background technique [0002] With the development of agricultural mechanization, more and more mechanization is used to harvest tubers of agricultural products, such as garlic, potatoes, radishes, sweet potatoes, etc. At present, there are many tuber harvesters. According to their working principles, their structures mainly include the following: Types: Excavating shovels are mainly fixed triangular shovels and strip shovels. The separation devices mainly include tooth bar type, lifting chain type, swing screen type, rotary drum type, etc. The tuber is seriously damaged, and the lifting chain separation device has a good separation effect, but the structural parts are easy to wear and consumes a lot of power. The swing screen separation device has a good soil separation effect, but its adaptability to the soil moisture content is not ...

[0002] With the development of agricultural mechanization, more and more mechanization is used to harvest tubers of agricultural products, such as garlic, potatoes, radishes, sweet potatoes, etc. At present, there are many tuber harvesters. According to their working principles, their structures mainly include the following: Types: Excavating shovels are mainly fixed triangular shovels and strip shovels. The separation devices mainly include tooth bar type, lifting chain type, swing screen type, rotary drum type, etc. The tuber is seriously damaged, and the lifting chain separation device has a good separation effect, but the structural parts are easy to wear and consumes a lot of power. The swing screen separation device has a good soil separation effect, but its adaptability to the soil moisture content is not strong. The separation ability of the sieve varies with the soil. Humidity increases and decreases, and the drum-type separation device is easy to adhere to the soil and be blocked by crop residues, and consumes a large amount of materials, which is easy to damage crop tubers. The above-mentioned products have single functions, narrow application areas, and poor harvest quality, which cannot meet the needs of agriculture. modernization needs
