Abstract
The invention relates to a grid type potato digging device comprising a main shaft, potato digging grid bars and a regulating fixed plate. The grid type potato digging device is characterized in that the main shaft is a stepped shaft, and a plurality of potato digging grid bars with the same shape and size are arranged on the cylindrical surface of the main shaft; the potato digging grid bars comprise potato digging sections, transition sections and extending sections, wherein the potato digging sections are straight lines, the transition sections are raised spiral lines, the extending sections are straight lines or curves, and the front ends of the potato digging grid bars are edged; and the regulating fixed plate is welded with the main shaft by central holes, and a penetrating angle regulating hole is arranged on the circumference 40mm away from the center of the regulating fixed plate. The grid type potato digging device has the advantages of simple structure and low manufacturing cost; and the potato digging grid bars comes into linear contact with soil so that the grid type potato digging device can be rapidly inserted into the soil, has low working resistance, greatly improves soil breaking effect and creates a good condition for subsequent separation.
Description
Technical field:
The present invention relates generally to potato digger, relates in particular to the structure of potato digger grid type pick potato device.
Background technology:
The principal mode of potato digger digger blade is fixed triangle shovel at present, can be divided into plane triangle shovel, curved surface shovel and flute profile shovel etc. according to shape, can be divided into single shovel, two shovel and many shovels according to the working width difference.Usually two shovels or many shovels leave the gap between two shovels, or add scuppit to reduce main shovel width, guarantee that scoop is not stopped up by soil block and plant undesirable root.Gap between two shovels is 40-50mm, the gap 30-40mm between many shovels.The shortcoming of fixed triangle shovel is that scoop is that face contact with soil, makes potato digger be difficult for burying, and working resistance is big, and the hack ability is bad and influence the native separation of potato.
Summary of the invention:
In order to overcome deficiency of the prior art, main purpose of the present invention provides a kind of grid type pick potato device, and it can make potato digger bury rapidly, has improved the hack effect greatly and has alleviated segregational load and working resistance.
The present invention solves the technical scheme that its problem adopts: a kind of grid type pick potato device, and by main shaft, pick potato grizzly bar, regulate fixed head and form.Be characterized in that main shaft is a multidiameter, on the face of cylinder of main shaft, be provided with a plurality of shapes, measure-alike pick potato grizzly bar; Pick potato grizzly bar is made up of pick potato section, changeover portion and extension, and pick potato section is a straight line, and changeover portion is the helix of projection; The extension is straight line or curve, and pick potato grizzly bar front end puts the first edge on a knife or a pair of scissors, and basil a is 20 °-35 °; Regulate fixed head by centre bore and main shaft seam, on the circumference of regulating fixed head center 40mm, have the penetrating angle adjustment hole.
The pick potato grizzly bar and the main shaft of described grid type pick potato device are one, and the alignment of shafts is to the distance L of pick potato grizzly bar tip
1Be 220-250mm, length overall L
2Be 440-500mm, pick potato grizzly bar diameter is the round steel of 12-18mm.
Described grid type pick potato device has a plurality of pick potato grizzly bars, and the centre-to-centre spacing of adjacent pick potato grizzly bar is 45-55mm, and the material of pick potato grizzly bar is the 45# steel.
The invention has the beneficial effects as follows: the present invention is simple in structure, and cost is low; Pick potato grizzly bar is that line contacts with soil, and potato digger can be buried rapidly, and working resistance is little, has improved the hack effect greatly, for separating the good condition of having created in the back.
Description of drawings:
Fig. 1 is an end view of the present invention.
Fig. 2 is a front view of the present invention.
1. pick potato grizzly bars are 2. regulated fixed head among the figure, 3. penetrating angle adjustment hole, 4. main shaft, 5. pick potato section, 6. changeover portion, 7. extension.
Embodiment:
