Backpack seed melon combined harvester

Abstract

The invention discloses a backpack seed melon combined harvester which comprises a transverse conveyor device, a pickup machine, a melon distributor, a melon guiding device, a melon discharging device, a lift conveyor and a melon seed extractor. The transverse conveyor device is mounted at the front of an engine, the pickup machine is mounted at the front of the transverse conveyor device, the melon distributor is arranged below the front of the pickup machine, the melon guiding device is arranged between the pickup machine and the transverse conveyor device, the melon discharging device is mounted on the rear upper portion of the pickup machine and corresponds to a melon inlet of the melon guiding device, the lift conveyor is mounted on the engine, and the melon seed extractor is mounted at the rear of the engine; a melon outlet of the melon guiding device corresponds to a melon inlet of the transverse conveyor device, a melon inlet and a melon outlet of the lift conveyor respectively correspond to a melon outlet of the transverse conveyor device and a melon inlet of the melon seed extractor, the pickup machine is of a roller type structure and comprises a pickup machine framework and a roller, the roller is movably connected onto the pickup machine framework, a plurality of pickup teeth are fixedly arranged on the peripheral surface of the roller, and the pickup machine framework is hinged to a framework of the transverse conveyor device. The backpack seed melon combined harvester has the advantages of high seed melon pickup efficiency and production efficiency and good profiling effect.

Description

technical field [0001] The invention relates to a machine for harvesting and deseeding seed melons, in particular to a backpack-type seed melon combine harvester. Background technique [0002] Seed melon is a vine grape fruiting crop. The fruit size is different, and the growth and distribution on the surface is in a disordered state. The conventional planting of seed melon adopts ridge cultivation and intertillage cultivation. Difficulties in the mechanized harvesting of seed melons, especially in the western region of my country, where the planting area of ​​seed melons is large, and most of them need to be picked manually in the field when harvesting, and then the picked melons are transported to the melon seeding machine for deseeding, which is labor-intensive. Very large, low work efficiency, labor-intensive and time-consuming. In many areas, due to the labor shortage in the autumn harvest season, the mature seed melons cannot be harvested in time, and the seed melons are...

AI Technical Summary

Problems solved by technology

Although it can complete the seed melon picking and threshing operations at one time, which saves labor, improves operation efficiency and reduces harvesting costs, but the backpack seed melon combine harvester has obvious shortcomings:

[0004] One is that its pick-up device is a spring-tooth type backward tilting chain rotation structure. The pick-up device includes a sprocket, an ear chain, a spring-tooth seat post and a pick-up tooth. The power is transmitted to the elevator by a locomotive and then transmitted When it comes to the pick-up device, the disadvantages of the pick-up device are: 1. Since the pick-up spring teeth pick or prick the melon under the action of power, it is easy to cause the seed melon to break, especially the melon (red slice) because the skin of the melon is thinner, which is more serious. ;2. Second-time tying of melons is a big waste; 3. The pick-up teeth are flexible and easy to deform, resulting in reduced pick-up efficiency; 4. Because the pick-up device is set backward, the copying effect is poor, and it is easy to cause the phenomenon of rubbing soil; 5. The pick-up device has a power effect, and the weeds are easy to entangle, and in serious cases, the whole machine will be paralyzed

[0005] The second is that its melon divider includes a single set of inverted "eight" type on the left and right and a middle melon divider. The profiling ability is poor, and there are many melon pressing phenomena; what's more, the melon divider is integral, and if the two sides of the ground are uneven, there will be suspension, forming the phenomenon of melon pressing

[0006] The third is that its horizontal conveying device is a vibrating melon chute, which has a poor effect of gliding melons. When there are weeds or broken melons, the effect is extremely poor, causing congestion
