Problems solved by technology

This process consumes a lot of power, and the crushing and loosening effect on the heavy and compacted soil is not obvious, that is, the soil is poor in crushing, which makes the pressure of the separation of the soil and potatoes behind it great, which affects the separation effect of the soil and potatoes.

Embodiment 1

[0009] Embodiment 1, see figure, moving shovel type potato excavator, comprises eccentric wheel (1), power take-off shaft (2), digging shovel (3), connecting frame rod (4), connecting rod (5), gearbox output Shaft (6), soil cutting disc (7), connecting rod (8), driving pulley (9), belt (10), lifting chain sieve (11), gathering potato plate (12), driven pulley (13 ), frame (14), gearbox (15), baffle plate (16), rubber skin (17), ground wheel (18) etc. constitute. The rear end of the digging shovel (3) is connected with the connecting rod (5) of the vibration mechanism, and the connecting rod (5) is set on the eccentric wheel (1), and the eccentric wheel (1) passes through the power output shaft (2) through the gearbox ( 15) Driven by the outgoing power shaft (6), the rotary motion of the eccentric wheel (1) is realized; the front end of the excavating shovel is connected with the connecting rod (4), so that the excavating shovel (3) is driven by the rotation of the eccentric wh...

Embodiment 2

[0011] Embodiment 2, see figure, the moving shovel type potato excavator is mainly carried out excavating work by the combination mode that the moving shovel mechanism and the lifting chain sieve type separation mechanism combine. The moving shovel mechanism is composed of an eccentric wheel, a connecting rod, a connecting rod and an excavating shovel. The lifting chain sieve type separation mechanism is composed of cast rubber drive wheel, rod chain, baffle, baffle skin and potato board. The reciprocating motion of the shovel breaks up the earth and potato diggings, reduces the traction resistance and increases the crushability of the soil. The soil cutting disc installed at the front mainly cuts off weeds, potato stems and soil clods. After the shovel lifts the soil to the bottom of the lifting chain sieve, the soil and potatoes are separated under the conveying action of the chain sieve, and the small pieces of soil fall through the gap between the chain bars, and the larg...

Abstract

The invention relates to a potato excavator matched with a tractor for use, belonging to the field of agricultural machinery. The existing potato picker mainly adopts the fixed shovel excavating mode, thus having the problems of large consuming traction force, poor soil breaking property, serious blocking condition and poor soil and potato separating effect, and the like. A vibration type potato excavator is good in soil breaking property and small in traction resistance, but the vibration amplitude of the whole potato excavator is large, so that the potato damaging rate is high in the separating process, and the work reliability of the whole excavator is low. The movable shovel type potato excavator adopts a novel movable shovel type extracting mechanism, due to the reciprocating motion of an excavating shovel, the breakage capability of a soil-potato excavating object is enhanced, the traction resistance is reduced, the soil-potato separating effect is improved, and the mechanical reliability is high. A lifting chain screen type separating mechanism is adopted, the potato damaging rate in the separating process is reduced, and the work reliability of the whole excavator is high. The potato excavator is suitable for clay and clay loam with severer soil hardening, and is also widely applied to sand and loessial soil easy to cultivate.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to a potato excavator matched with a tractor. Background technique [0002] At present, the potato harvesters in my country mainly use fixed digging shovels. For loamy soils and clay textures with severe soil compaction, the angle of digging shovels can only be adjusted according to the soil texture. The function of crushing soil is poor, and the working resistance is large, which cannot solve the problem of digging up large clods. , resulting in different degrees of clogging of potato harvesters, poor separation effect of soil and potatoes, low rate of clear potatoes, high rate of damaged potatoes and high loss rate. The vibrating potato excavator has good soil crushing performance and small traction resistance, but the vibration of the whole machine is large, the potato damage rate is high during the separation process, and the reliability of the whole machine is low. ...
