Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a harvester. Background Technology

[0002] In recent years, the number of harvesters on the market has been increasing. The impurity content of ears is one of the performance indicators for corn harvesters or corn harvesters that harvest ears and stalks simultaneously. Adding a debris-removing fan to the elevator to reduce the ear impurity content is a mainstream approach in the market. However, in most mainstream corn harvesters that harvest ears and stalks simultaneously, the elevator is located on the right side of the machine. Adding a debris-removing fan to the elevator increases the overall width of the machine and reduces its maneuverability. Furthermore, a debris-removing fan installed on the right side of the machine can easily obstruct the driver's view of the right-side rearview mirror during operation, making it difficult for the driver to see what's in the mirror. Therefore, a harvester is needed that does not obstruct the driver's view in the rearview mirror, has good maneuverability, and can effectively remove impurities such as husks, reducing the ear impurity content. Summary of the Invention

[0029] Refer to this Figures 1-6 As shown, the harvester of the present invention includes a picking platform 1, a cab 5 located above the rear end of the picking platform 1, a reflector 6 located at the upper end of the cab 5, a lift 2, a peeling mechanism 7, a peeling frame (not labeled), a waste removal fan 4, and an air inlet 3. When the harvester is operating, the picking platform 1 at the front of the harvester grabs the corn stalks and separates them from the corn ears. The elevator 2, located between the picking platform 1 and the peeling mechanism 7, includes a left side plate 21 and a right side plate 22. The left and right side plates 21 and 22 form an elevator channel 23, which further conveys the corn ears from the picking platform 1 upwards towards the harvester. The peeling mechanism 7, mounted on a peeling frame (not labeled), peels the corn ears from the elevator 2. The peeling mechanism 7 is located behind the elevator 2. An air inlet 3 is located above the elevator 2 and connected to the elevator channel 23. An air inlet channel 31 is formed inside the air inlet 3, which removes the corn stalks and husks from the elevator channel 23. The intake air passage 31 has a cross-section that gradually narrows from bottom to top. The exhaust fan 4 is located on the right side of the intake air section 3 and is connected to the intake air section 3. The exhaust fan 4 sucks in and discharges the corn stalks and husks from the intake air section 3. The exhaust fan 4 is located above the elevator 2. Part or all of the exhaust fan 4 is located between the left side plate 21 and the right side plate 22, which reduces the left and right width of the harvester and improves the overall passability. The corn ears that have been discharged by the exhaust fan 4 and peeled by the peeling mechanism 7 enter the ear box. The upper end of the cab 5 is connected to the rearview mirror 6. The exhaust fan 4 does not obstruct the rear view in the rearview mirror 6. This implementation reduces the impurity content of the ears and does not affect the driver's view in the rearview mirror, resulting in good overall passability.

[0030] Since the specific structure, relative positions, connection relationships and functions of other components of this invention are all mature existing technologies, they will not be described in detail here. The structure of the air inlet 3 and the exhaust fan 4 of this invention will be described in detail below.

[0031] Refer to this Figures 3-8 As shown, the air inlet 3 includes a first housing part 32 and a first conveying part 33 connected to the first housing part 32; the first housing part 32 and the first conveying part 33 together form an air inlet channel 31; the first housing part 32 includes an inclined guide plate 321 mounted on the side of the first housing part 32, the inclined guide plate 321 is located on the side close to the impurity removal fan part 4, the impurity removal fan part 4 is located above the inclined guide plate 321, the first conveying part 33 is connected to the impurity removal fan part 4, and the bottom end of the first housing part 32 is connected to the left side plate 21 and the right side plate 22 respectively. Specifically, the bottom end of the first housing part 32 is provided with mounting holes 9 on the left and right sides respectively, and the first housing part 32 is connected and assembled with the elevator 2 through the mounting holes 9; this solution can eliminate the dead corner of impurity accumulation caused by the impurity removal fan 4, and facilitate the large-area absorption of corn stalks and husks in the elevator channel 23 by the air inlet of the air inlet 3, which facilitates smooth impurity removal and improves the impurity removal rate. The first conveying section 33 includes a top plate 333 mounted on the top of the first conveying section 33, a connector 332 for connecting the top plate 333 and the first conveying section 33, and a mounting shaft 331 for mounting the exhaust fan 42; the connector 332 includes a hinge 3321 and a latch 3322; one end of the top plate 333 is movably connected to the first conveying section 33 via the hinge 3321, and the other end is closably mounted on the first conveying section 33 via the latch 3322, which allows the top plate 333 to be opened for easy observation and maintenance; the mounting shaft 331 drives the exhaust fan 42 to rotate.

[0032] Refer to this Figure 4 , Figures 6-8As shown, the impurity removal fan unit 4 includes a second housing unit 41 and an impurity removal fan 42. The second housing unit 41 includes a fan mounting part 411 for mounting the impurity removal fan 42, a second conveying part 412 connected to the fan mounting part 411, and a discharge part 413 connected to the second conveying part 412. The fan mounting part 411 is cylindrical, and the discharge part 413 is arc-shaped. The discharge part 413 is configured as an arc transition opening to guide the smooth discharge of corn stalks and husk impurities. The conveying part 412 and the discharge part 413 together form an impurity removal channel. The fan mounting part 411 includes a first mounting part 4111 located at the top and a second mounting part 4112 located at the bottom. The first mounting part 4111 is integrally formed with the second conveying part 412 and the discharge part 413. The first mounting part 4111 and the second mounting part 4112 are respectively provided with bent edges, and the first mounting part 4111 and the second mounting part 4112 are connected by the bent edges. The impurity removal fan 42 includes several blades 421, for example, four blades. The four blades 421 are connected to the mounting shaft 331 and arranged circumferentially. The end of the blade 421 near the first conveying part 33 is provided with a flange 4211. The flange 4211 can increase the exhaust air volume of the impurity removal fan 4 in the direction of the discharge part 413. A reinforcing plate 422 is provided between two adjacent blades 421. The two ends of the reinforcing plate 422 are respectively connected to the two adjacent blades 421. The reinforcing plate 422 increases the strength of the blades 421. Two spaced blades 421 are respectively provided with a lever 423. The lever 423 is connected to the end of the blade 421 near the first conveying part 33. The lever 423 can guide the corn stalks and husks impurities in the air inlet channel 31 into the inner cavity of the impurity removal fan 4.

[0033] When the harvester is working, the engine power is transmitted directly or indirectly to the mounting shaft 331 via the belt, which drives the mounting shaft 331 to rotate, and in turn drives the blades 421 to rotate. The rotation of the blades 421 generates wind force, which sucks the corn stalks and husks carried in the lifting channel 21 during transportation into the air intake channel 31 and the waste discharge channel in sequence, and finally discharges them to the outside of the machine body through the discharge part 413.

[0034] It will be apparent to those skilled in the art that various modifications and variations can be made to the exemplary embodiments described above without departing from the spirit and scope of the invention. Therefore, it is intended that this invention cover modifications and variations falling within the scope of the appended claims and their equivalents.
