Self-propelled medical material excavator

Abstract

The invention discloses a self-propelled medical material excavator which comprises a frame, an engine, driving wheels, a driver's seat, a steering wheel, an excavation mechanism and a hydraulic system. The excavation mechanism comprises two rear support arms hinged onto the frame, front support arms are hinged to the upper ends of the two rear support arms, a fork beam is hinged to the lower endsof the two front support arms, a short support arm is fixed in the middle of the fork beam, a rear beam is connected between the two rear support arms, and a front beam is connected between the two front support arms. The hydraulic system comprises a hydraulic oil tank, a hydraulic pump and a hydraulic distributor, lifting oil cylinders are mounted among the upper ends of vertical columns and themiddle upper portions of the rear support arms, a translation oil cylinder is mounted between the middle of the rear beam and the middle of the front beam, and an excavation oil cylinder is mounted between the middle of the front beam and the front end of a short support arm. The self-propelled medical material excavator is simple in structure, low in manufacturing cost, small in excavation resistance and low in energy consumption, and medical materials cannot be damaged and are completely picked up.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a self-propelled excavator for medicinal materials. Background technique [0002] Traditional harvesting of root medicinal materials is done manually with shovels or special forks, which has low work efficiency and high labor intensity. In order to improve work efficiency and reduce the labor intensity of drug growers, many excavating machines for rhizome medicinal materials are disclosed in the prior art, and most of these machines are rear suspension or rear traction type medicinal material excavating machines. The main disadvantages of these medicinal materials excavation machines are: 1) they are generally suspended or drawn by rubber-tyred agricultural power locomotives, and the walking rubber wheels press on the unharvested medicinal materials, causing serious damage to the medicinal materials; 2) the turned-out medicinal materials are buried again. In the s...

Problems solved by technology

The main disadvantages of these medicinal materials excavation machines are: 1) they are generally suspended or drawn by rubber-tyred agricultural power locomotives, and the walking rubber wheels press on the unharvested medicinal materials, causing serious damage to the medicinal materials; 2) the turned-out medicinal materials are buried again. In the soil, it is not conducive to picking up the medicinal materials; 3) The traction resistance is large, and it needs to be equipped with a high-horsepower agricultural power locomotive, which consumes a lot of energy.
