Embodiment Construction

[0015] Below in conjunction with the best examples shown in the accompanying drawings for further details:

[0016] The described small vibrating screen potato excavator, when operating, combines the belt tensioning clutch (6) to transmit the power of the tractor to the swing mechanism (1) through the transmission mechanism (8), and then drives the excavating shovel assembly (7) to do Reciprocating vibration. The digging shovel (7-1) digs up the potato ridge, and the potato-soil mixture slides backward along the digging shovel face, and part of the crushed soil falls from between the grid bar teeth, and the remainder is sent to the separating screen (7-2). The separation screen (7-2) reciprocates, and the soil clods are shattered under the action of the separation rod, and the soil clods and broken soil with a diameter smaller than the gap between the rods leak down from the gap between the rods. At the same time, due to the tomographic effect during the vibration process, Po...

Abstract

The invention relates to the technical field of mechanized potato sowing equipment, in particular to a digger for potatoes in dry land with all membrane double ditches. The small vibration-sieve type potato digger comprises a frame (2), a diagonal draw bar (3), a digging shovel component (7), a swing mechanism (1), a driving mechanism (8), a limit mechanism (5), a clutch (6) and a hanging mechanism (4). The frame (2) is hooked to a tractor traction box. A rectangular sliding groove is formed in the hanging mechanism (4), a beam frame of the limit mechanism (6) penetrates the sliding groove, and the position, where the beam frame of the limit mechanism (6) is positioned, can change the depth of the digging. The digging shovel component (7) is fixedly jointed to the swing mechanism (1) through bolts. The driving mechanism (8) is disposed between the hanging mechanism (4) and the swing mechanism (1). The diagonal draw bar (3) is disposed between the swing mechanism (1) and the hanging mechanism (4). Due to the fact that the small vibration-sieve type potato digger can be matched with a small-power walking tractor to meet the requirements for digging potatoes in small plots such as terraced fields and hilly mountains, the problems that small potato diggers are large in digging resistance and unadjustable in penetrating angles of the digging shovels are solved.

Description

Technical field: [0001] The patent of the present invention is an agricultural machine, specifically a potato excavator suitable for small plots such as terraced fields, hills and mountains. Background technique [0002] Potato harvesting operations in small plots such as terraced fields and hilly areas in my country have basically remained at the traditional stage of manual seedling cutting, pickaxe digging potatoes, and manual picking, which has seriously affected the large-scale production of potatoes. [0003] The mechanized harvesting of small potatoes in foreign countries started early, developed rapidly, and has a high level of technology, but there are differences between foreign countries in terms of natural conditions, potato varieties, planting, and agronomy. In addition, due to the small plots of potato cultivation in our country and the low purchasing power of farmers, it is difficult for foreign potato harvesters to be widely used in our country. [0004] The ...
