[0002] The corn harvester elevator is one of the important parts of the corn harvester. Its main function is to transport the ears transported by the auger to the ear box. The elevator is mainly composed of the elevator driven shaft, elevator chain, elevator shell, elevator conveyor belt and elevator wheel. It is usually located on the right side of the tractor, connected to the ear auger in front and connected to the upper support plate of the rear frame in the back. In general, the corn harvester elevator plays an important role in the corn harvesting process and can effectively improve the harvesting efficiency and quality.

[0003] However, when the prior art is actually used, a large amount of debris and leaves are generated during the corn harvesting process of the corn harvester elevator. When the corn cobs are lifted and transported, the debris and leaves generated during the corn harvesting process are easily transported to the inside of the cob box along with the corn cobs. As a result, the debris and leaves need to be cleaned after the corn is harvested, which affects the corn harvesting efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a corn harvester elevator with a debris removal function to solve the problem that the corn harvester elevator proposed in the above background technology will generate a large amount of debris and leaves during the corn harvesting process during use, so that when the corn harvester elevator lifts and transports the corn ears, it is easy for the debris and leaves generated in the corn harvesting process to be transported to the inside of the ear box along with the corn ears, resulting in the need to clean the debris and leaves after the corn is harvested, thereby affecting the corn harvesting efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: comprising an elevator housing, a debris removal opening is provided through the front side surface of the upper end of the elevator housing, a mounting groove is fixedly installed on the inner wall of the debris removal opening, a debris removal groove is fixedly installed on the upper end of the mounting groove, and a suction fan is fixedly installed through the side end of the debris removal groove;

[0006] A support frame is fixedly installed on the outer wall of the middle part of the elevator shell, and a driving motor is fixedly installed on the upper end of the support frame. The outer curved surface of the transmission shaft part inside the driving motor is fixedly installed with the first main sprocket and the second main sprocket in sequence from front to back, and the outer ends of the first main sprocket and the second main sprocket are respectively connected to the first secondary sprocket and the second secondary sprocket through chain transmission, and the first transmission shaft and the second transmission shaft are respectively fixedly installed in the middle of the first secondary sprocket and the second secondary sprocket, and rotating rollers are respectively fixedly installed on the outer curved surfaces of the first transmission shaft and the second transmission shaft, and plastic brush strips are fixedly installed on the outer curved surfaces of the rotating rollers.

[0007] Preferably, a lifting conveyor belt for lifting and transporting corn ears obliquely upward is rotatably connected to the interior of the elevator shell via a rotating shaft.

[0008] Preferably, there are two impurity removal ports, which are symmetrically distributed on the upper front side of the elevator shell.

[0009] Preferably, the inner transmission shaft portion of the drive motor is rotatably connected to the outer side wall of the elevator housing through a bearing seat support.

[0010] Preferably, the first transmission shaft and the second transmission shaft are rotatably connected to the inner wall of the installation groove via a rotating shaft.

[0011] Preferably, there are several plastic brush strips, which are symmetrically distributed on the outer curved surface of the rotating roller.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the lifting conveyor belt of the utility model lifts and transports corn ears obliquely upward along the inside of the elevator housing, the driving motor is turned on by control. When the driving motor is turned on, the first transmission shaft and the second transmission shaft are driven to rotate synchronously. When the first transmission shaft and the second transmission shaft rotate synchronously, the rotating roller is driven to rotate synchronously. When the rotating roller rotates synchronously, the plastic brush strip is driven to rotate synchronously. When the plastic brush strip rotates synchronously, the corn ears transported obliquely upward can be rotated and cleaned, and the debris and leaves removed by the rotation can be discharged outward through the impurity discharge groove, thereby realizing the effect of removing impurities from the corn ears while transporting the corn ears obliquely upward;

[0014] 2. The utility model can also control the opening of the suction fan when the plastic brush strip can rotate and clean the corn ears that are transported upward and obliquely. When the suction fan is turned on, negative pressure will be generated inside the debris discharge trough. When negative pressure is generated inside the debris discharge trough, the debris and leaves swept by the plastic brush strip can be auxiliary sucked and discharged, thereby further facilitating the removal of impurities from the corn ears.

A dust removal opening 3 is penetrated and opened on the front side of the upper end of the elevator shell 1, and there are two dust removal openings 3, which are symmetrically distributed on the upper front side of the elevator shell 1. An installation groove 4 is fixedly installed on the inner wall of the dust removal opening 3, and a dust removal groove 5 is fixedly installed on the upper end of the installation groove 4, and a suction fan 6 is fixedly installed on the side end of the dust removal groove 5;

[0022] Working principle: When in use, the utility model controls the opening of the lifting conveyor belt 2. When the lifting conveyor belt 2 is turned on, the corn ears can be lifted and transported obliquely upward along the inside of the elevator housing 1. When the lifting conveyor belt 2 lifts the corn ears along the inside of the elevator housing 1 to obliquely upward, the driving motor 8 is controlled to be turned on. When the driving motor 8 is turned on, it will drive the first main sprocket 9 and the second main sprocket 10 to rotate synchronously. When the first main sprocket 9 and the second main sprocket 10 rotate synchronously, the first sub-sprocket 11 and the second sub-sprocket 12 will be driven to rotate synchronously through the chain transmission. When the first sub-sprocket 11 and the first sub-sprocket 12 rotate synchronously, the first sub-sprocket 11 and the second sub-sprocket 12 will be driven to rotate synchronously. When the two sprocket wheels 12 rotate synchronously, the first transmission shaft 13 and the second transmission shaft 14 will be driven to rotate synchronously. When the first transmission shaft 13 and the second transmission shaft 14 rotate synchronously, the rotating roller 15 will be driven to rotate synchronously. When the rotating roller 15 rotates synchronously, the plastic brush strip 16 will be driven to rotate synchronously. When the plastic brush strip 16 rotates synchronously, the corn ears transported upward and inclined can be rotated to clean them, and the debris and leaves removed by the rotation can be discharged outward through the impurity discharge groove 5, so as to realize the function of removing impurities from the corn ears while transporting the corn ears upward and inclined.

[0023] At the same time, when the plastic brush strip 16 can rotate and clean the corn ears that are transported upward and obliquely, the suction fan 6 can be controlled to be turned on. When the suction fan 6 is turned on, negative pressure will be generated inside the impurity discharge trough 5. When negative pressure is generated inside the impurity discharge trough 5, the debris and leaves swept by the plastic brush strip 16 can be auxiliary sucked and discharged, thereby further facilitating the removal of impurities from the corn ears.
