Technical Field

The invention relates to an excavating device, in particular to an excavating device of a beet harvester, and belongs to the field of agricultural machinery.

Background

Beta is a biennial herb with cone-shaped or spindle-shaped root and succulent. The stem is upright, the basal leaves are rectangular and round, the upper part of the stem is long, the stem is wrinkled and uneven, the lower part of the stem is provided with a thick and protruded leaf vein which is full-edged or slightly wavy, the stem is thick, the stem and the leaf are grown mutually, the stem and the leaf are small, the flower is gathered, the flower is divided into strips or is rectangular and round, and the upper part of the fruiting body is slightly fleshy; beet is native to western and southern europe along the coast, and is transplanted from sweden to spanish, and china is mainly distributed in xinjiang, black dragon river, inner mongolia, etc. They are good for warm crops, but they are strong in cold resistance. The beet grows well on the deep and soft soil rich in organic matters; sugar beet is a major sugar source in addition to sugar cane. Beet is commonly cooked or salted in the united states, and russian beet pottage is the traditional beet soup in eastern europe. Sugar beet is the most important commercial type, and fodder beet and leaf beet are cultivated as in most crops. When the traditional beet harvester is used for harvesting beet, the beet passes through the pulling wheel, the pulling wheel pulls the beet out of the soil, and then the beat beats the beet from the pulling wheel onto the first transmission chain to complete the whole digging process; the method is only suitable for direct seeding or transplanting, the error of the distance between two ridges is required to be not more than 5cm, no mulching film is laid, and the method can be used for harvesting; and when harvesting, the pulling wheel is adjusted when needed, so that the phenomenon that the beet is cut due to the fact that the ridges are not straight is prevented, and therefore when harvesting, an operator needs to have an adaptive process, and harvesting efficiency is reduced.

Disclosure of Invention

The invention aims to solve the problem that the harvesting efficiency is reduced because an operator needs an adaptive process during harvesting because a pulling wheel is adjusted when the traditional beet harvester needs to harvest beets to prevent the beets from being cut due to the fact that ridges are not straight, and further provides an excavating device of the beet harvester.

The technical scheme adopted by the invention for solving the problems is as follows: the beet sugar beet harvester comprises a pulling wheel group, a digging shovel and a transmission chain group, wherein the pulling wheel group is arranged on a main beam at the rear end of a beet sugar beet harvester frame, the digging shovel is arranged on the beet sugar beet harvester frame, the digging shovel is positioned below the pulling wheel group, the transmission chain group is arranged on the beet sugar beet harvester frame, and the starting end of the transmission chain group is positioned in front of the digging shovel.

Furthermore, the pulling wheel set consists of two pulling wheels arranged side by side.

Furthermore, the two pulling wheels are arranged in a V shape.

Furthermore, the included angle between the upper surface of the conveying chain group and the horizontal plane is 0-15 degrees.

Furthermore, the conveying chain group comprises two conveying chains and a plurality of chain rods, the two conveying chains are arranged on the frame of the beet harvester side by side, the plurality of chain rods are arranged between the two conveying chains side by side, and two ends of each chain rod are respectively connected with the two conveying chains.

Furthermore, the conveying chain group further comprises an intermediate supporting chain, the intermediate supporting chain is arranged between the two conveying chains, chain grooves are formed in the outer surface of the intermediate supporting chain, and the middle of each chain rod is located in one chain groove.

Further, the conveying chain group also comprises a plurality of pins, and the end part of each chain rod is detachably connected with the conveying chain through the pins.

The invention has the beneficial effects that: the invention does not need to carry out ridge alignment before operation, has simple operation and strong adaptability, and can lead an operator to adapt to the operation technique quickly; the rear end of the invention can harvest and lay the sugar beet with mulching film, the invention can also change fittings at any time, and change the fittings into the original structure mode, and the sugar beet can be harvested by directly using the pulling wheel; the invention has strong adaptability and high harvesting efficiency, and is a preferred machine type for users in the market.
