Description

Garlic digging harvester

Technical field

The utility model relates to a kind of garlic digging harvester, particularly a kind of garlic digging harvester that garlic and cane can be separated.

Background technology

Existing garlic harvesting only has the excavation function mostly, when the results garlic, owing to can't simultaneously garlic be separated with its cane, cause when harvest operation, cane is wrapped on excavation frame, digger blade or the gauge wheel of reaping machine, has a strong impact on the operation effectiveness and the operating efficiency of results.Such reaping machine, with the tractor mounting means on, a kind of front end that is mounted in tractor, the longitudinal size of a whole set of machinery is excessive, because the reach of tractor center of gravity, so reduced the adhesive force of driving wheel, but increased simultaneously the load of tractor front-wheel, it is not only sunk easily in wet soft ground, and headland turn is also dumb.And the another kind of garlic digging harvester that can be suspended on the tractor rear portion, because during operation, the wheel spreading is on garlic, so very easily make garlic impaired during results, the grade of reduction garlic directly is affected peasant's economic benefit.

The utility model content

The utility model is to provide a kind of simple in structure, compact, flexible and convenient operation, dependable performance, garlic loss percentage low at the deficiency in the background technology, and can once finish the cutting and separating cane, excavates garlic, separates the high efficiency garlic digging harvester of soil operation.

Its concrete solution is: be used to cut the cutting and separating mechanism of cane and can be installed in the excavation conveying mechanism two parts that are used to excavate garlic between the tractor front and back wheel constitute by being installed in the tractor front end.Be provided with straw shift wheel, cutterbar assembly and auger conveyor in the cutting and separating mechanism.They all are connected with the transmission mechanism that is driven by the tractor outputting power.And in the excavation conveying mechanism, the grid strip screen that is provided with plough shovel, band conveyor and screens out assorted soil in the garlic.Wherein, band conveyor is connected with the transmission mechanism that is driven by the tractor outputting power.

Being provided with one in the described cutting and separating mechanism joins by quadric chain and tractor front bumper, and the ceding of Taiwan that links to each other with the tractor lifting arm by draw-off mechanism, cutterbar assembly is installed in the bottom of this ceding of Taiwan front end, and being positioned at the front portion of this ceding of Taiwan by the straw shift wheel that transmission mechanism and tractor dynamic power output flywheel belt pulley is connected, auger conveyor is positioned at the rear portion of cutterbar assembly.

Be provided with one in the described excavation conveying mechanism and can be connected the hanger bracket on the crossbeam between the tractor front and rear wheel, and band conveyor and grid strip screen all are connected with this hanger bracket by connector, and make the plough shovel be connected the front end of band conveyor, grid strip screen is arranged on the rear portion of band conveyor, simultaneously, band conveyor is connected with the transmission mechanism that drives by tractor dynamic power outlet side output wheel.

In addition then, excavating the connector described in the conveying mechanism should adopt one can regulate the connector of its length so that can adjust the angle of penetration of plough shovel easily and the degree of depth that shovel is gone into when harvest operation at least.

Moreover band conveyor is provided with son gathers the baffle plate of garlic, and, be provided with the gap of separable assorted soil between this baffle plate and band conveyor.

The utility model adopts by cutting and separating mechanism, excavates the split type Combination Design that conveying mechanism two parts constitute, it can be cut down the garlic cane by cutting mechanism easily, by auger conveyor cane is sent outside the machine, thoroughly avoid the winding of cane to body, can shovel out by the garlic that the excavation transport portion will be stayed in the soil again simultaneously, and by band conveyor the garlic of excavating is delivered to and to be separated assorted soil on the grid strip screen, thereby once finish the cutting and separating of garlic cane, the excavation of garlic also separates operations such as assorted soil on it.The utility model is not only simple in structure, compact, easy for installation, configuration rationally, flexible operation, security of operation be stable, and, also can improve results efficient of garlic and the loss percentage that reduces garlic greatly, guarantee the grade quality of garlic.
