Abstract

A two-stage conveying and separating device of a potato combine comprises a bar conveying device consisting of double chains and bars, wherein the double chains are driven by a driving chain wheel and a driven chain wheel through a working shaft; a claw type conveying device arranged on the rods is arranged on the surface of the rod conveying device at intervals of two rods, and the claw type conveying device and the surface of the rod conveying device form an inclination angle of 94 degrees according to the rotating direction of the rod conveying device. The conveying and separating device can grab small soil blocks in the potatoes falling from the primary conveying and separating device into pieces by using the claw type conveying device, and the small soil blocks fall to the ground; the potatoes falling from the first-stage conveying and separating device are scrubbed by the claw type conveying device, so that the attached soil can be scrubbed; the claw type conveying device can avoid the situation that potatoes falling from the primary conveying and separating device directly fall onto the bars to generate large-amplitude bounce, the mutual impact between the potatoes and the conveying device for the potatoes and between the potatoes and the conveying device for the bars is reduced, and the damage of the potatoes due to peeling is reduced.

Description

Two-stage conveying and separating device of potato combine harvester

Technical Field

The invention relates to a farmland harvesting operation machine, in particular to a two-stage conveying and separating device of a potato combine harvester.

Background

The potato combine harvester generally comprises a frame, a soil cutting disc device and an excavating device which are positioned at the lower part of the front end of the frame, and a conveying and separating device which is arranged on the frame. The conveying and separating devices of different combine harvesters are different in number, the simplest combine harvester is only provided with one-level potato conveying and separating device, potatoes dug out by the digging device, soil blocks and root and stem mixtures are conveyed to the conveying and separating device, and then the potatoes, soil and the root and stem are separated once and output, fall onto the ground and are picked up manually. Because the harvester needs to manually pick up the potatoes, the harvesting efficiency is low, and most of the harvested potatoes are adhered with attached soil, the harvester is increasingly replaced by a harvester provided with a multi-stage potato conveying and separating device.

The potato combine harvester is characterized in that the potato combine harvester is provided with a multistage conveying and separating device, the one-stage conveying and separating device positioned behind the digging device consists of a double chain driven by a chain wheel and a bar conveying device consisting of bars arranged on the double chain, the bar conveying device is used for separating a potato soil mixture dug by the digging device for the first time, and the separated potatoes are lifted to the upper part of the potato combine harvester through the next-stage lifting device and are sent into a potato collecting box or directly loaded into a vehicle.

The potato soil mixture sent by the digging device cannot be thoroughly crushed based on the primary conveying and separating device of the potato combine harvester, so that potatoes sent by the primary conveying and separating device have attached soil and are mixed with a small amount of small soil blocks, the potatoes are directly sent to the lifting device to be lifted to a high position and collected, and the obtained potatoes are not clean, and the quality and the selling price of the potatoes are influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at increasing second grade transport separator at the back of potato combine one-level transport separator and between the hoisting device, carry the one-level that separator sees off thoughtlessly have a small amount of little clods and attach the potato of soil and carry out the secondary separation, clear away the broken little clod, the potato attaches soil and drops, makes the potato that is seen off at last by the hoisting device become the clean potato that does not contain soil, improves the quality and the market value of results potato.

The utility model relates to a two-stage conveying and separating device of a potato combine harvester, which comprises a bar conveying device consisting of a double chain and a bar, wherein the double chain is driven by a driving chain wheel and a driven chain wheel through a working shaft; on the surface of the bar conveyor, a finger-like claw conveyor mounted on the bars is arranged every other two bars, and the claw conveyor and the surface of the bar conveyor form an inclination angle of 94 degrees according to the rotation direction (clockwise circulation in fig. 1) of the bar conveyor.

The utility model discloses separator is carried to second grade installs in potato combine one-level transport separator's rear end below, is the horizontality and accepts the potato that falls from separator is carried to the one-level, carries out the separation of secondary potato soil through it after, gives follow-up potato hoisting device through the slide.

The utility model has the advantages that:

1. the utility model discloses increased imitative finger shape claw formula conveyor on bar conveyor, made the little clod that thoughtlessly has in the potato that falls from the one-level transport separator and grabbed the bits of broken glass by claw formula conveyor's a plurality of L shape fingers of falling, fallen to ground through the clearance between the bar conveyor bar.

2. The potatoes falling from the primary conveying and separating device are scrubbed by a plurality of inverted L-shaped fingers of the claw type conveying device, soil attached to the surface can be scrubbed off, and the potatoes fall to the ground through gaps among the bars of the bar conveying device.

3. By utilizing the finger-like claw type conveying device, the potatoes falling from the primary conveying and separating device are prevented from directly falling onto the bar conveying device to generate large-amplitude bounce, the mutual impact between the potatoes and between the potatoes and the bar conveying device are reduced, the damage of the broken skins of the potatoes is reduced, and the improvement of the quality of the recovered potatoes is facilitated.

Drawings

Fig. 1 is a three-dimensional schematic diagram of the structure of the present invention.

The symbols in the drawings illustrate that: 1-driving chain wheel, 2-working shaft, 3-claw type conveying device, 4-bar, 5-double chain and 6-driven chain wheel.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in figure 1, the two-stage conveying and separating device of the potato combine comprises a bar conveying device consisting of a double chain 5 driven by a driving chain wheel 1 and a driven chain wheel 6 through a working shaft 2 and a bar 4 arranged on the double chain; on the surface of the bar conveyor, at every other two bars, a finger-like (five inverted L-shaped fingers) claw conveyor 3 is arranged, which is mounted on the bars and forms an angle of inclination of 94 ° with the surface of the bar conveyor in the direction of rotation of the bar conveyor (clockwise in fig. 1).

Claims

1. A two-stage conveying and separating device of a potato combine comprises a bar conveying device consisting of a double chain (5) and bars (4), wherein the double chain (5) is driven by a driving chain wheel (1) and a driven chain wheel (6) through a working shaft (2); the device is characterized in that finger-like claw type conveying devices (3) arranged on the rods are arranged on the surfaces of the rod conveying devices at intervals of two rods, and the claw type conveying devices and the surfaces of the rod conveying devices form an inclination angle of 94 degrees according to the rotating direction of the rod conveying devices.
