A sugar beet digging device

Abstract

The invention relates to a beet digger, which is characterized by comprising a machine frame, a combined digging part and a driving system, wherein the machine frame comprises a first cross beam, a second cross beam, a third cross beam between the first and second cross beam, a first longitudinal beam and a second longitudinal beam; the combined digging part comprises a disc axle arm frame, one end of the disc axle arm frame is connected with the third cross beam, the other end of the disc axle arm frame is connected with two connecting shafts, and the other ends of the two connecting shafts are both connected with a disc; eccentric wheels are arranged below the longitudinal beams on the side of the first cross beam; the two eccentric wheels are connected by a first drive shaft which is provided with a digger blade positioned at a lower nonaligned place between the two discs; the driving system comprises a gear box arranged on the second cross beam, the input end of the gear box is connected with a power device, and the output end of the gear box is connected with a second drive shaft and a gear oil pump respectively; the second drive shaft drives the eccentric wheels to rotate through a chain wheel drive device; the input end of the gear oil pump is connected with an oil tank; the output end of the gear oil pump is connected with a hydraulic motor; and the power output end of the hydraulic motor is connected with one of the two discs.

Description

technical field [0001] The invention relates to a digging device, in particular to a sugar beet digging device matched with a wheeled tractor. Background technique [0002] Sugar beet is the second most economically valuable sugar crop after sugarcane in the world. Sugar beet digging and harvesting is an important process in the sugar beet production process, and it is a key link to ensure the increase of sugar beet production and income. Digging and harvesting machinery is an indispensable mechanical equipment for modern sugar beet agricultural production. It can greatly reduce the labor intensity of the sugar beet harvesting process, improve production efficiency, and increase farmers' income. [0003] There are various types of sugar beet digging devices in use, and the following shortcomings are common: 1) Most digging devices do not have a limit mechanism, and the depth of digging parts is unstable and fluctuates greatly; 2) Most of the digging parts are passive parts,...

Problems solved by technology

[0003] There are various types of sugar beet digging devices in use, and the following shortcomings are common: 1) Most digging devices do not have a limit mechanism, and the depth of digging parts is unstable and fluctuates greatly; 2) Most of the digging parts are passive parts, and the digging resistance is large. Poor adaptability and working stability; 3) It is inconvenient to adjust the row spacing of excavation parts, and the roots have side leakage, which has poor adaptability to land plots with different soil conditions, which affects the excavation effect

During work, the sugar beets are dug out under the joint action of the slider and the disc, and enter the conveying and cleaning part at the rear, which contains a lot of soil; the slider and the disc are passive parts, affected by the soil conditions, the effect of entering the soil is not good Good, relatively poor adaptability
