Technical Field

The utility model relates to an agricultural machine, in particular to a corn thresher.

Background

After harvesting, the corn needs to be threshed for subsequent further processing. The existing threshing machine usually adopts a spiral threshing rib structure, and in order to ensure the threshing rate, the threshing machine with the structure needs to apply larger extrusion force to the corn, so that more corn kernels are damaged.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a corn thresher, can solve the not enough of prior art, reduce the damage of kernel of corn when guaranteeing the threshing rate.

In order to solve the technical problem, the utility model adopts the following technical proposal.

The utility model provides a corn thresher, which comprises a frame, the hub connection has threshing cylinder in the frame, install driving motor in the frame, driving motor threshes a section of thick bamboo rotation through the drive wheel drive, threshing cylinder inner wall evenly is provided with the first threshing roller of a plurality of, be provided with first muscle of threshing on the first threshing roller, it has the second threshing roller that parallels with first threshing roller to peg graft along the axis in the threshing cylinder, the second threshing roller is connected in the frame, the second threshing roller includes the oil bag, the oil bag is connected with oil pipe, the external fixed surface of oil bag has a plurality of base plate, be provided with the spout along the radial of second threshing roller on the base plate, install the slide between two adjacent base plates, the both ends of slide respectively with spout sliding connection, slide fixed surface has the second to thresh the muscle.

Preferably, the oil bag is sleeved outside a piston of the oil cylinder, and a cylinder body of the oil cylinder is fixed on the frame.

Preferably, a sealing sliding ring is arranged between the cylinder body of the oil cylinder and the threshing cylinder.

Preferably, the first threshing rib comprises a first diagonal rib and a second diagonal rib, the first diagonal rib and the second diagonal rib are symmetrically arranged along the axis direction of the first threshing roller, and the included angle between the first diagonal rib and the second diagonal rib is 20-70 degrees.

Preferably, the first diagonal brace is connected with the second diagonal brace, and a diversion trench is arranged at the joint of the first diagonal brace and the second diagonal brace.

Preferably, the top of the second threshing rib is provided with a plurality of blind holes, a threshing plate is arranged in the blind holes through springs, and the threshing plate is in clearance fit with the blind holes.

Adopt the beneficial effect that above-mentioned technical scheme brought to lie in: the utility model discloses use the structure of "two-sided threshing", utilize first muscle of threshing and the second muscle of threshing to thresh the processing simultaneously to the maize in threshing cylinder, improved threshing efficiency. More importantly, the oil quantity in the oil bag can be increased or decreased through the oil pipe, so that the oil pressure of the oil bag is changed, the pressure in the corn threshing process is continuously controllable, and the corn kernels are effectively protected. By utilizing the telescopic adjustment of the oil cylinder, the sizes of a threshing area and a stirring area in the threshing cylinder can be changed, the stirring uniformity of the corns in the whole threshing cylinder is improved, and the threshing efficiency is improved. The oblique draw bar that the symmetry slope set up can realize the operation of threshing of two directions, realizes fully threshing under the state of less threshing pressure, but the oblique draw bar of this kind of structure causes maize gathering jamming easily, cooperatees through the second threshing roller with can stretch out and draw back the adjustment, the utility model discloses can effectively solve the problem of maize gathering jamming. The arrangement of the diversion trench can enable the corn kernels to flow out of the threshing area quickly, and damage to the corn kernels is reduced. The threshing plate movably arranged on the second threshing rib can axially rotate and radially swing in the process of contacting with corns, the threshing angle in the process of contacting with the corn kernels is self-adaptive, and the damage to the corn kernels caused by pressing the threshing ribs on the surfaces of the corn kernels is further reduced.
