Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of crop harvesting machines, and particularly relates to a self-propelled leek harvesting and bundling integrated machine. BACKGROUND

[0002] The history of leek in China is very long. With the progress of science and technology, various grains and vegetables are planted on a large scale. The important factor limiting the development of leek planting area is the mechanization problem. In the whole leek production process, the harvesting operation accounts for about 50% of the total workload, which is the most labor-intensive and time-consuming work link. When the leek planting area is large, it is too low in efficiency to rely on manual harvesting. Moreover, if it is planted on a large scale, the labor force for harvesting is relatively small, and the labor cost is very high, which increases the planting cost of leek, and the benefit per unit area also decreases accordingly.

[0003] With the adjustment of the planting structure, the planting area of leek is increasing year by year. Leek belongs to a labor-intensive industry, and the planting methods are various, the technical procedures are complex, and the degree of scale is low. The cost of adapting to large-scale harvesting robots is too high, and small leek harvesters can better adapt to the leek planting situation in China. The current mainstream leek harvesters on the market have two modes: backpack type and hand-pushed type.

[0004] The backpack type leek harvester is mainly composed of a backpack engine, a front end of a reed support and a cutter. The engine uses oil as fuel to provide power for the end rotary cutter. The reed support can guide the leek stems and support the cutting. This backpack type leek harvester has the advantages of fast speed, convenient use, and strong adaptability to complex terrain and small-scale planting. However, its disadvantages are also obvious. The end rotary cutter cutting design has the problems of poor cutting stub quality, high missing cutting rate, and stem winding. At the same time, the form of engine backpacking still relies on manpower. The rural labor force is now seriously aging, and the elderly cannot work for a long time with a backpack. Moreover, after completing the harvesting, the leek cannot be gathered and bundled, and manual work is needed to collect and bundle the scattered leek, which is low in efficiency and consumes a lot of human resources. Therefore, the backpack type leek harvester cannot completely replace manual work to complete the leek harvesting work.

[0005] The hand-pushed type leek harvester is controlled by one person, and includes a rotary cutter, a reed support, a conveyor belt and a motor. Compared with the backpack type leek harvester, the leek can be arranged in a flat and neat manner after the hand-pushed type leek harvester completes the harvesting, which is convenient for manual collection. Moreover, the overall weight of the machine body is borne by the wheel set, which reduces the manual load and reduces the labor intensity. However, although the hand-pushed type leek harvester improves the work efficiency compared with the backpack type leek harvester, it still needs manual pushing for auxiliary work, and does not completely liberate the labor force.

[0006] Therefore, there is currently a need for a full-automatic leek harvester that can autonomously realize harvesting, collecting and bundling to better meet the needs of the current leek planting industry. SUMMARY

[0041] After the harvest is completed, in order to disinfect and sterilize the leek roots and fertilize at the same time, the ash mechanism 4 uniformly spreads the wood ash on the just-harvested leek roots. The mechanism is improved by referring to the principle of gear pump to realize ash scraping. The wood ash in the ash storage box 94 is transported into the underlying leakage groove 97 through the corrugated barrel 93 to realize ash transportation, is scattered by the ash scattering rocker 91, and is scattered forward and backward, so that it is uniformly scattered from the leakage groove 97, and the ash scattering action is completed.

[0051] In order to facilitate subsequent baling collection, the cut leeks need to be lifted to a certain height. Since the friction type belt transmission has simple structure, large speed regulation range and small loss, it is very suitable for small agricultural machines. Therefore, the friction type belt transmission is adopted.

[0052] The overall frame 11 is provided with a chassis steering mechanism 7 at the lower part.

[0053] The chassis steering mechanism 7 comprises a steering engine 48, a lead screw 49, a steering connecting rod 50, a support plate 51, a driving wheel 52, a driving motor 53, a light axle bearing seat 54, a chassis light axle 55, a motor fixing piece 56, a customized flange 57, a flange connecting piece 58, a sliding block guide rail 59, a flange connecting plate 60, a large flange coupling 61, one end of the sliding block guide rail 59 is connected with the large flange coupling 61 through the flange connecting plate 60, the output shaft of the steering engine 48 is connected with the large flange coupling 61, the sliding block guide rail 59 is controlled to rotate through the steering motor, the lead screw 49 is perpendicular to the sliding block guide rail 59 and is connected with each other through the customized flange 57 and the flange connecting piece 58, the two ends of the lead screw 49 are connected with the steering connecting rod 50 through a pin shaft, the steering connecting rod 50 is connected with the driving wheel 52 through the chassis light axle 55, the upper end of the chassis light axle 55 is connected with the whole frame 11 through the light axle bearing seat 54 and the support plate 51, and the lower end of the chassis light axle 55 is connected with the driving motor 53 through the motor fixing piece 56.

[0054] Since the distance between the leek ridges is small, in order to avoid crushing the leeks, the harvester needs to turn at a small radius, and the field soil roughness is large, so the differential in-place turning friction is large, and therefore the chassis steering mechanism 7 is used to reduce the turning radius. In the chassis steering mechanism 7, the steering connecting rod 50 is rigidly connected with the driving wheel 52, the angle is kept unchanged, the sliding block guide rail 59 is turned at a fixed angle, the turning angle of the driving wheel 52 on the inside of the turning is larger, and the turning is realized.
