Abstract

The utility model discloses a root excavator which is a harvesting mechanism for potato and sugar beet type root crops. An excavating shovel is provided at the front part of a rack, and a cleaning wimble is arranged at the rear part of the rack, the upward side of the cleaning wimble is arranged with a gear. The root excavator excavates and looses roots, cleans the roots out of the soil surface, and moves the roots to one side. Because the cleaning components has flexibility, and the gap is big at the front and small at the rear, so the roots with different sizes can be intact to be excavated and cleaned out without leave-out, thereby the utility model overcomes the disadvantages that some tools make high breakage and high leave-out of the root crop.

Description

Root digger

The utility model relates to a kind of potato, beet class root crop harvest machinery.

In the harvest time of sweet bud is the peak season of labor intensive power, though the existing long production history of sugarbeet harvester, but popularization and application aborning, particularly the rural area under existing system is actually rare, large-scale reaping machine is subjected to the plot, line-spacing, the restriction of several factors such as use cost, though mini-excavator has use, operation quality is unsatisfactory, can not as combined wheat harvester, generally be accepted by the peasant, the excacation parts of existing type generally are V shape or shovel, during work, by digging fork or digger blade the piece root is dug out from soil, they are had relatively high expectations to broadcasting capable linearity, and percentage of damage and to dig unclean rate higher influences peasant's income, hand digging efficient is too low again, and this contradiction never is well solved.

The purpose of this utility model provides a kind of dig out rate height, root digger that percentage of damage is lower.

The technical solution of the utility model is: two row digger blades are arranged below the horizontal frames front portion, below the frame rear portion and the digger blade correspondence a pair of cleaning cone is housed, thumb wheel is equipped with in the cleaning cone top, cleaning cone and thumb wheel are by the drive disk assembly driven in rotation.

But this root digger a tractor serves several purposes, root crops such as results beet, potato, radish, with middle fraction horsepower tractor, digger blade digs the piece root the mellow soil from both sides, cleaning cone is progressively routed up soil surface with the piece root in the middle of two side direction, less demanding to broadcasting horizontal linearity, and is broken few, do not have to leak and dig, it is little that soil buries loss.

Fig. 1 is the structural representation of root digger.

Fig. 2 is the right view of Fig. 1.

Below in conjunction with accompanying drawing the embodiment of root digger is done and to be described in further detail, industry is done in root digger and the supporting suspension of middle-size and small-size wheel tractor, do industry delegation at every turn, a row loosening spade (2) is respectively installed in frame two longeron front portions, two shovels of every in the illustrated embodiment row, front and back position staggers, in case stop up stifled.Fixing on longeron with spade of loosening spade is equipped with hoof shovel before the spade elbow, and the easy resistance that buries is less.There is a cleaning cone (3) every row loosening spade back at longeron rear portion, totally two.Two cleaning cone switched in opposite, turning to is to make progress from the centre to inner rotary, loosening spade has been dug the loose piece root that also is embedded in the soil clean out soil surface from soil.Cleaning cone (3) is the garden steel pipe of a band pointed cone head, is evenly equipped with the Yangtze River Delta shape wing of several band flexible edge on its tube wall.Four triangle metal wings are arranged among the embodiment, and the wing is fixed with rubber strip on the limit, can not damage the piece root because of it is soft.The structure of delta wing makes the gap of two cleaning cones pre-large post-small, last gap has only 60 millimeter, therefore can be the unearthed clearly successively from front to back face of the big and small piece root that is dug pine by two row loosening spades, there is a thumb wheel (4) position of being partial to vertical center line one side in the top of two cleaning cones (3), the rubber wing that possesses certain intensity is arranged on the wheel hub of thumb wheel, it is dialled to opposite side the piece root of emersion soil face so that pick up with higher speed rotation.And do industry for next line and go out road clearly, anti-stops velamen soil buries.The rotation of cleaning cone and thumb wheel (4) drives cardan axis (1) and gear by the power take-off of tractor back, and chain wheel set realizes.

Claims (4)

1, root digger is made up of frame, drive disk assembly, digging element and cleaning member etc., it is characterized in that: two row loosening spades (2) are installed below the frame front, below the frame rear portion and the loosening spade correspondence a pair of cleaning cone (3) is installed, there is thumb wheel (4) top of cleaning cone, and cleaning cone and thumb wheel are by the drive disk assembly driven in rotation.

2, root digger as claimed in claim 1 is characterized in that: loosening spade (2) is to connect triangle curved surface shovel body to constitute below an elbow spade.

3, root digger as claimed in claim 1 is characterized in that: cleaning cone (3) is the garden steel pipe of band pointed cone head, is evenly equipped with the Yangtze River Delta shape wing of the flexible edge strip of several bands on its tube wall, and drive disk assembly drives it by interior upwards outwards rotation.

4, root digger as claimed in claim 1 is characterized in that: on its circumference of hub of thumb wheel (4) of cleaning cone top several flexible plectrums are arranged.
