Description

Technical Field

[0001] The invention belongs to the technical field of harvesters, and in particular to a drum-type harvester head and a harvester. Background Art

[0002] A harvester is a machine that is used to harvest crops. It is generally used for harvesting rice, wheat, corn, and forage grass. Harvesters come in two types: cutter-type and feeder-type. Feeder-type harvesters often feed the harvested crops into the machine for crushing or threshing, while cutter-type harvesters cut the crops down and lay them in strips on the crop field. Feeder-type harvesters generally crush the stems and leaves of the crops, but there is a certain loss and breakage rate for the crop products that need to be collected. For some crops that require intact stems and leaves, cutter-type harvesters are needed. Although cutter-type harvesters can relatively reduce the loss and breakage rate of crop products, they also require additional crop collection, which increases the workload. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to overcome the deficiencies in the prior art and provide a drum-type harvester head. The present application provides the following technical solutions:

[0004] It includes a casing, and a feed port and a discharge port are respectively provided on the side of the casing; a rotatable harvesting drum is installed at the feed port, and a reciprocating feeding structure is provided between the feed port and the discharge port; a harvesting knife and a material shifting structure are provided on the harvesting drum, the harvesting knife cuts the crops, the material shifting structure shifts the cut crops to the feeding structure, and the feeding structure delivers the crops to the discharge port.

[0005] The feeding structure includes a conveyor chain and a feeding motor. The feeding motor is used to drive the conveyor chain to rotate. A plurality of feeding plates are installed on the conveyor chain. The feeding plates reciprocate with the conveyor chain.

[0006] The feeding plate pushes the crops to move, exerting a pushing force on the crops as a whole and reducing damage to the crops.

[0007] The harvesting knife is arranged at the bottom of the harvesting drum, and the material-diverting structure includes a first material-diverting ring, a second material-diverting ring and a third material-diverting ring which are sequentially arranged above the harvesting knife. The first material-diverting ring is evenly provided with a number of hook-shaped teeth, the second material-diverting ring is provided with a number of second material-diverting teeth, and the third material-diverting ring is provided with a number of third material-diverting teeth.

[0008] By setting up three material-diverting rings, the hook-shaped teeth on the first material-diverting ring rotate to hook the crops to prevent them from falling over. The material-diverting teeth on the second and third material-diverting rings extend to the sides of the crops, support the crops, and keep them vertically entering the machine body. Then, they are pushed through the feeding plate, and the collected crops are vertically and neatly arranged.

[0009] A motor seat is fixedly provided in the casing, a rotary motor is provided in the harvesting drum, and a motor shaft of the rotary motor is mounted on the motor seat for driving the harvesting drum to rotate relative to the motor seat.

[0010] A built-in motor is used, and the rotating motor is placed in the harvesting drum, and then installed through the motor base so that it rotates relative to the motor base. When the crops are harvested, the harvesting drum is the main contact position with the crops. The rotating motor is hidden in the harvesting drum, which can provide good protection for the rotating motor.

[0011] The conveyor chain comprises a plurality of interconnected chain links, and foot seats are fixed on the chain links. Both ends of the feeding plate are mounted on the foot seats.

[0012] A ring seat is provided at the bottom of the harvesting drum, and the harvesting knife is detachably fixedly mounted on the ring seat, so as to facilitate the removal and replacement of a damaged or worn harvesting knife.

[0013] The casing is provided with a protection tube, one side of the protection tube is provided with a groove, the conveying chain is hidden in the groove, and the footrest extends from the side of the protection tube.

[0014] By setting up a protective tube, the conveyor chain is hidden in the conveyor chain groove to prevent the crops from coming into contact with the conveyor chain and being drawn into the conveyor chain when the feeding plate pushes the crops, thereby affecting the operation.

[0015] An inclined material guide plate is provided on one side of the material inlet close to the material outlet to facilitate material feeding.

[0016] Furthermore, the present application also provides a harvester that adopts the above-mentioned drum-type harvester head.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] By arranging a harvesting knife and a material shifting structure on the harvesting drum, when the harvesting drum rotates, the harvesting knife cuts the crops while the material shifting structure shifts the crops into the casing through the feed port, and sends the crops to the discharge port for collection through the feeding structure, and the damage rate to the crops is low.
