[0018] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the utility model.

The terms "up", "down", "left", "right", "top", etc. indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0020] As shown in Figs. 1-2 A double-elevator corn harvester, comprising an elevator 1, two of which are oppositely arranged on both sides of a harvester body 2, and the front end of the harvester body 2 is provided with a header 3, and the ears harvested by the header 3 enter the two elevators 1 on both sides for lifting and transportation to realize harvesting and storage.

[0021] Through the above arrangement, two elevators 1 are arranged to cooperate with the header 3 to lift and transport the ears harvested by the header from both sides, which increases the width of the lifting and transportation channel compared to a single elevator, thereby improving the efficiency of transporting the ears and improving the harvesting efficiency of the harvester. At the same time, the double elevators on both sides of the header 3 facilitate the connection of the ears harvested by the header 3 from two directions and the transportation, avoiding the accumulation of ears and broken straws in the auger 5 or the blockage between the elevators 1, and improving the overall working efficiency of the harvester.

[0022] In addition, by arranging two elevators 1, when one side of the elevator 1 or the related components fails, the other side can continue to perform harvesting operations, thereby reducing the loss caused by downtime.

[0023] Specifically, the single-elevator four-row harvester on the market has a limited width of a single elevator 1 during operation, and the ears harvested by the header 3 are transported by only one elevator, and the efficiency of transporting the ears is relatively slow. The embodiment configures two elevators 1 to cooperate with the header 3, which is equivalent to an elevator 1 transporting the ears of only two rows of corn, greatly reducing the working pressure of the elevator 1 and improving the transportation efficiency of the ears.

[0024] In the double-elevator corn harvester of the embodiment, two peeling machines 4 are further arranged on the harvester body 2, the peeling machines 4 are located at the end of the elevator 1 to receive the lifted and transported ears and perform peeling, and the size of the peeling machine 4 matches the width of the elevator 1.

[0025] Specifically, the four-row machine currently on the market is usually equipped with a twenty-roller peeling machine 4 for a single elevator 1, but due to the width limitation of the single elevator 1, it is difficult to lay the fruit clusters on the entire peeling span of the peeling machine 4 after being transported, so the utilization rate of the peeling machine 4 is relatively low. The embodiment arranges a twelve-roller peeling machine 4 behind each elevator 1 on the basis of the double elevator 1, which matches the width of the elevator 1. The fruit clusters transported are better laid on the twelve-roller peeling machine 4, and the two peeling machines 4 combined together are equivalent to twenty-four rollers, which greatly improves the peeling efficiency and in turn improves the harvesting efficiency of the harvester.

[0026] In the double-elevator corn harvester of the embodiment, an auger 5 is arranged between the elevator 1 and the header 3, which drives the fruit clusters harvested by the header 3 to move to the bottom end of the elevator 1 for lifting by the elevator 1.

[0027] When the machine model of the embodiment is used for harvesting corn, the header 3 picks the corn clusters, which are transported to the right elevator 1 and the left elevator 1 through the auger 5, transported to the right peeling machine 4 and the left peeling machine 4 through the elevator 1, peeled by the peeling machine 4, and connected to the header 3 and the elevator 1 by the auger 5, so as to drive the fruit clusters harvested by the header 3 to the loading port of the elevator 1 for transportation.

[0028] In the double-elevator corn harvester of the embodiment, two augers 5 are arranged, which are respectively connected to the header 3 and the elevators 1 on both sides, and are arranged perpendicular to the elevators 1 to fit the header 3 and in turn connect the fruit clusters.

[0029] Specifically, two sections of augers 5 are arranged to match the two elevators 1, and the rotating directions of the two sections of augers 5 are opposite, so as to drive the fruit clusters harvested by the header 3 to the two sides respectively, realize simultaneous transportation of the left and right elevators 1, and improve the transportation and harvesting efficiency.

[0030] In the double-elevator corn harvester of the embodiment, the loading port is arranged on the side of the auger 5 close to the header 3, the header 3 includes a plurality of header channels 6, and the header channels 6 are communicated with the loading port to facilitate the fruit clusters to enter the auger 5.

[0031] Specifically, taking a four-row harvester as an example, the header channels 6 are arranged with four rows to simultaneously harvest four rows of corn, the loading ports of the two augers 5 are respectively communicated with the two header channels 6 on the left side and the two header channels 6 on the right side, and each auger 5 receives the fruit clusters harvested by the two header channels 6 and drives the fruit clusters to move left or right to approach the loading port of the elevator 1, so as to enter the elevator 1 to realize lifting and transportation, and improve the transportation efficiency.

[0032] Preferably, the left and right sides of the harvester are provided with separate header 3, elevator 1, auger 5 and peeler 4, so that when a fault occurs in one side of the harvester, the other side of the harvester can be used for work, reducing the loss of the harvester.

[0033] The double-elevator corn harvester of the embodiment further comprises a grain bin 7, which is arranged at the discharge end of the peeler 4, and the peeler 4 receives the ears lifted by the elevator 1 and transports the ears into the grain bin 7 after peeling.

[0034] Specifically, the grain bin 7 is arranged at the rear end of the harvester body, and the peeling roller in the peeler 4 is arranged along the extension direction of the elevator 1 to receive the transported ears and peel them, and the peeled ears are thrown into the grain bin 7 for storage, and the grain is unloaded when the bin is full.

[0035] In the double-elevator corn harvester of the embodiment, a pulverizer 8 is further arranged below the header 3 to pulverize the corn stalks separated after the ears are harvested by the header 3, facilitating the movement of the harvester body 2 in the harvesting direction.

[0036] The pulverizer 8 is arranged to pulverize the stalks after the ears are picked by the header 3, avoiding the blocking of the large volume of stalks to the movement of the harvester body 2 and affecting the normal work.

[0037] Specifically, the harvester of the application further comprises a transmission part: the engine outputs power by combustion, part of which is used for walking, and the other part is transmitted to each component through the main power gear box, thereby realizing the operation of the entire harvesting mechanism.
