Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a corn harvester capable of harvesting both stalks and ears of corn and avoiding grass entanglement. Background Art

[0002] Corn is the main crop planted in my country. After the corn ears are harvested, straw treatment is often required. The traditional treatment method is direct burning or stacking, but these methods not only pollute the environment, but may also cause harm to the land. With the development of society, in modern agricultural production, corn harvesters that can harvest both stalks and ears are generally used for harvesting to achieve efficient harvesting operations. However, when the existing corn harvesters that can harvest both stalks and ears are in use, the connecting shaft of the front cutting table is close to the ground, and it is easy to get entangled with weeds during the work process. The entangled weeds are difficult to detach from the shaft, and will accumulate more and more, which can easily cause the harvester to work abnormally. Therefore, at this stage, it is often necessary to stop the harvester and clean the weeds on the shaft during work, which is not only troublesome, but also greatly reduces the harvesting efficiency. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a corn harvester which can harvest both stalks and ears of corn and avoid grass entanglement.

[0004] In order to solve the above technical problems, the technical solution provided by the present invention is a corn harvester for harvesting both stalks and ears of corn, which can avoid grass entanglement, comprising a corn harvester for harvesting both stalks and ears of corn, and a main body;

[0005] An axle tube is sleeved on the outer side of the connecting shaft of the front cutting platform on the main body of the corn harvester for harvesting both stalks and ears. The axle tube is rotatably connected to the frame of the front cutting platform. A plurality of knife seats are evenly arranged on the surface of the axle tube, and a cutting knife body is installed on the knife seat.

[0006] Two or three cutting blades are mounted on each blade seat. The cutting blades are bent outwards relative to each other, and a cutting blade is arranged on one side of the cutting blade.

[0007] Furthermore, the shaft tube is driven by an engine on the main body of the corn harvester for harvesting both stalks and ears.

[0008] Furthermore, the shaft tube is connected to the output shaft of the gearbox on the main body of the stalk-and-ear corn harvester through a chain.

[0009] The advantages of the present invention over the prior art are as follows: the present invention improves the existing stalk-and-ear corn harvester, adds a pipe shaft to the connecting shaft of the front cutting table, and arranges a plurality of cutting blades on the pipe shaft, so that weeds and other debris that are about to be entangled on the connecting shaft can be cut off during the normal corn harvesting process, avoiding grass from winding around the connecting shaft, ensuring the normal operation of the equipment, using a chain to transmit power, and working stably and reliably.

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0015] Embodiment 1, in combination with Figure 1-2 , a corn harvester for harvesting both stalks and ears of corn capable of avoiding entanglement with grass, comprising a corn harvester body 1 for harvesting both stalks and ears of corn;

[0016] A shaft tube 3 is sleeved on the outer side of the connecting shaft 2 of the front header on the main body 1 of the corn harvester for harvesting both stalks and ears. The shaft tube 3 is rotatably connected to the frame of the front header. A plurality of knife seats 4 are evenly arranged on the surface of the shaft tube 3. A cutting knife body 5 is installed on the knife seat 4.

[0017] Two or three cutting blades 5 are mounted on each blade seat 4 . The cutting blades 5 are bent outwards relative to each other, and a cutting blade 501 is disposed on one side of the cutting blade 5 .

[0018] During specific implementation, the main body 1 of the corn harvester for both stalk and ear harvesting moves forward to harvest corn, the shaft tube 3 rotates, and the cutting blade 5 rotates accordingly, so that the weeds in the place where the cutting blade 5 can sweep the blade can be cut, avoiding the weeds from being entangled on the connecting shaft 2, thereby ensuring the continuous operation of the main body 1 of the corn harvester for both stalk and ear harvesting.

[0019] In this embodiment, the shaft tube 3 is driven by the engine on the main body 1 of the corn harvester for both stalks and ears, and no additional power mechanism is required, which saves cost and is beneficial to the spatial layout of various structures.
