Technical Field

The utility model relates to the field of corn harvesting equipment, in particular to a corn harvester.

Background

The corn harvester is an operation agricultural machine for harvesting corn stalks by using machinery according to agricultural requirements when corn is mature or near mature, is developed for novel energy development and reducing labor intensity of farmers, and is characterized in that the corn harvester advances along the corn ridge direction during operation, a cutter cuts off the corn stalks, the stalks are output in the right direction of a conveying chain and are naturally placed, and the corn stalks are separated from corn cobs in the conveying process to finish harvesting.

When the corn harvester is working, corn plants are firstly contacted with the conical part at the front end of the divider, the front conical part of the divider divides a front harvesting area into a cutting area and a to-be-cut area, crops in the cutting area are reversely conveyed to a conveying chain along the divider and are conveyed to a header collecting frame backwards through the conveying chain, corn fruits are collected to a middle slotting part of the collecting frame through a packing auger arranged on the collecting frame, corn is conveyed further through a slot, the corn is collected conveniently and quickly, but corn is easy to drop out, corn silk is not cleaned, so that dropped corn kernels are conveyed together with corn cobs, corn silk, corn husks and the like, the corn cobs are easily blown away together through a fan in the prior art, so that corn cobs and corn husks are wasted, only corn cobs, corn husks and the like are easily blown away, the corn cobs and the corn cobs are left to be conveyed to a storage box for storage, and the problem that the corn cobs storage time is influenced occurs.

Disclosure of utility model

The utility model provides a corn harvester, which aims to solve the problems that corn kernels, corn silk and the like cannot be properly separated, waste is caused and corn cob storage is affected when corn is harvested by the corn harvester in the prior art.

In order to achieve the above object, the present utility model provides the following solutions:

The utility model provides a maize picker, includes harvesting equipment, corn cob transmission equipment, corn cob splitter, corn cob processing equipment and storage facilities in proper order, corn cob processing equipment includes from the top down's subassembly of skinning, corn kernel filter component and corn kernel collection subassembly that sets gradually, the subassembly of skinning includes a plurality of horizontal installation's transfer roller and skinning gyro wheel, and drive transfer roller and skinning gyro wheel pivoted first driving motor, transfer roller and skinning gyro wheel set up in turn.

According to the corn cob peeling machine, the corn cob peeling assembly, the corn cob filtering assembly and the corn cob collecting assembly are added in the working flow of the corn harvester, corn cobs are peeled, cleaned, corn cobs are filtered, corn cobs are collected, the corn cobs are independently recovered and stored, the corn cobs, corn husks and the like are filtered, transported and recovered, the corn cobs are guaranteed to be stored, and the corn cobs and the corn husks are clamped and pulled through the conveying rollers and the peeling rollers in a rotating mode.

Further, the diameter of the peeling roller is smaller than that of the conveying roller, the rotation directions of the conveying roller and the peeling roller are opposite, and the conveying roller is tangential to the peeling roller.

The corn silk of ripe or to ripe corn cob stretches out and sags from the corn cob front end, this device adopts conveying gyro wheel transportation corn cob to when the corn cob passes by, the crack of its sagged corn silk contact conveying gyro wheel and skinning gyro wheel because conveying gyro wheel and skinning gyro wheel rotate in opposite directions, the corn silk of sagged corn can be by conveying gyro wheel and skinning gyro wheel centre gripping and downward pulling, reaches the purpose of clearance corn silk, simultaneously, at conveying gyro wheel and skinning gyro wheel in-process that pulls the corn silk, corn husk also can be by conveying gyro wheel and skinning gyro wheel centre gripping and pulling, further reaches the purpose of clearance corn husk, reduces the time of follow-up clearance corn husk.

Further, a spiral groove is formed in the conveying roller, a spiral protrusion is arranged on the peeling roller, and the spiral groove is matched with the spiral protrusion.

The friction on conveying roller surface can be increased to spiral recess, simultaneously, when conveying roller and peeling roller drag maize skin and corn silk, make the kernel of corn easily drop, the kernel of corn that drops can't pass through conveying roller and peeling roller, also can't be transported away, lead to piling up on conveying roller and peeling roller, influence the conveying of maize cob, spiral protrusion on the peeling roller can drive the kernel of corn to spiral bellied terminal, avoid accumulational kernel of corn to influence the conveying of maize cob.

Further, the conveying roller and the peeling roller are both arranged in the corn channel, a gap is arranged between one end of the peeling roller and the corn channel, and the gap is positioned at the tail end of the spiral protrusion.

After the spiral bulge can drive the corn grain to the tail end of the spiral bulge, the notch is used for the corn grain to pass through, the corn grain is prevented from piling up at the tail end of the spiral bulge, because the spiral bulge is arranged on the peeling roller, when the peeling roller rotates, the spiral bulge can also rotate together, the spiral bulge can then have an initial end and a tail end according to the rotating direction of the peeling roller, and at the moment, the spiral bulge turns to the tail end from the initial end, so the notch is arranged at the tail end of the spiral bulge, and the spiral bulge can drive the corn grain to the notch correctly.
