Description

Self-propelled fresh corn cob combine harvester

technical field

The utility model relates to a fresh corn harvester, in particular to a self-propelled fresh corn cob combined harvester.

Background technique

The planting area of fresh corn in my country is 12 million mu, and the area is still increasing. Fresh corn is generally cooked and eaten directly on the ears, and the ears must be intact and undamaged when harvested, otherwise the appearance damage will affect sales and economic benefits. At present, fresh corn is harvested manually by picking ears, and after picking the ears, the straw is used as green fodder for mechanized storage. Existing corn ear harvesters are all aimed at the harvesting of grain corn, which is harvested in the mature stage, and the loss rate and grain breakage rate in the operation process are required to be controlled within the index range. The ear picking parts of the existing corn ear harvester used to harvest fresh corn are likely to cause damage to the ear. It can be seen that manual harvesting of fresh corn is labor-intensive, low in production efficiency, and high in production cost, while harvesting fresh corn with the existing corn ear harvester is very damaging, and the straw cannot be silaged for recycling.

Contents of the invention

The purpose of the utility model is to solve the above problems and provide a self-propelled fresh corn cob combined harvester with small ear damage, high production efficiency, low production cost and effective utilization of straw.

In order to achieve the above object, the utility model adopts the following technical solutions: the utility model self-propelled fresh corn ear stalk combined harvester includes a chassis and a transmission system arranged on the chassis, an ear box, a driver's cab, and a The longitudinal straw conveying device, the clamping and feeding mechanism, the straw cutting and throwing device, which are arranged in sequence from front to back on the chassis, also include the ear harvesting platform, the secondary longitudinal conveyor belt, and the tertiary longitudinal conveyor belt. The harvesting platform is composed of a stubble cutter, a transverse conveyor belt, a first-stage longitudinal conveyor belt, a clamping mechanism, an ear picking roller group, and a transverse straw conveying device. The stubble cutter is set in front of the transverse conveyor belt, and the transverse conveyor belt Slope forward and downward along the longitudinal direction, and the ear picking roller group is arranged above the belt surface of the transverse conveyor belt, and the ear picking roller group is inclined backward and downward along the longitudinal direction, and a clamping mechanism is arranged above the ear picking roller group, and the clamping mechanism is arranged along the longitudinal direction The upper rear is inclined, and a horizontal straw conveying device is installed at the rear end of the ear picking roller group. The middle outlet of the horizontal straw conveying device is connected with the front entrance of the longitudinal straw conveying device. A first-level longitudinal conveyor belt is symmetrically arranged left and right, and a second-level longitudinal conveyor belt is arranged at the rear end of the first-level longitudinal conveyor belt. A third-level longitudinal conveyor belt is arranged at the rear end of the second-level longitudinal conveyor belt. Corresponds to the entrance of the ear box.

As a preferred solution of the present utility model, the ear picking roller group is a pair of smooth cylindrical rollers arranged in parallel, and the clamping mechanism is provided with a pair of rubber belts pressed against each other in its inclined surface.

As a preferred solution of the present utility model, a depth-limiting wheel is arranged in front of the stubble cutter of the fringe-picking harvesting platform.

After adopting the above-mentioned technical scheme, the beneficial effects that the self-propelled fresh edible corn cob combined harvester provided by the utility model have are:

Because the fringe harvesting platform of the utility model is provided with a fringe-picking roller group above the belt surface of the transverse conveyor belt, the fringe-picking roller group is inclined longitudinally to the rear and downward, and a clamping mechanism is arranged above the fringe-picking roller group, and the clamping mechanism It is inclined longitudinally to the rear and upward, and a horizontal straw conveying device is arranged at the rear end of the ear-picking roller group, and the middle outlet of the transverse straw conveying device is connected with the front-end inlet of the longitudinal straw conveying device. Therefore, during the traveling operation, the rubber belt of the clamping mechanism clamps the fresh corn stalks and transports them to the rear and upwards. The conveying height is continuously raised to the rear and upward, and the ears of fresh corn are hindered by a pair of smooth cylindrical rollers inclined longitudinally and downward. . And the operating efficiency is more than ten times that of manual labor. And because the utility model is provided with the longitudinal straw conveying device, the clamping and feeding mechanism, and the straw chopping and throwing device sequentially from front to back on the chassis, the straw after ear picking falls into the horizontal straw conveying device downwards, and the The horizontal straw conveying device conveys the straw to the longitudinal straw conveying device, feeds it through clamping, chops it, and finally throws it to the feed truck, so that the straw does not fall to the ground and cleanly harvests silage. Therefore, the effects of small ear damage, high production efficiency, low production cost and effective utilization of straw are obtained.
