Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment technology, specifically to a corn harvester header with adjustable row spacing. Background Technology

[0002] Currently, many domestic manufacturers produce corn harvesters with fixed ridge spacing. When the ridge spacing changes significantly, the lifting device will knock down the standing corn stalks. Therefore, to solve the above problems, this invention provides a corn harvester header with adjustable ridge spacing. When the corn ridge spacing changes significantly, it is necessary to match different headers with different ridge spacings. This type of header can harvest corn with different ridge spacings, saving resources for producing headers with different ridge spacings. Summary of the Invention

[0003] The main objective of this invention is to provide a header for a corn harvester with adjustable row spacing.

[0004] To address the aforementioned problems, this invention provides a corn harvester header with adjustable row spacing, comprising a header frame and a conveyor and agitator. On the support beam of the header frame, a portion of the ear-picking box frame can rotate a certain angle to the left or right using a central anchor pin. This changes the row spacing without requiring all ear-picking boxes to rotate. A metal plate is linearly welded to the support beam, and anchor pins are symmetrically welded to the center of the metal plate. Four arc-shaped holes, centered on the anchor pins, are drilled on the metal plate, their dimensions matching the four holes on the ear-picking box frame. A hole is also drilled at the center of each of the four holes on the ear-picking box frame, its size matching the anchor pin. This allows the ear-picking box frame to rotate a certain angle on the support beam around the anchor pin. When row spacing needs adjustment, the four fastening screws on the ear-picking box frame are loosened, the frame is rotated to the desired row spacing, and then the four screws are tightened to adjust the row spacing.

[0005] The header mechanical transmission works through chains, sprockets, shafts, universal joint drive shafts, transmission boxes, and picking boxes. The shafts are fixed to the header frame via bearings and bearing seats. The transmission box and picking box should not collide with the stirring base plate during installation. The stirring is connected to the main machine via chain teeth, chains, chain teeth, shafts, sprockets, and chains. The shafts are fixed to the header frame via bearings and bearing seats.

[0006] The guards on both sides of the header are fixed to the ear-picking box frame, and the dividers on both sides are connected to the guards; the sizes of other guards and dividers are matched with different sizes depending on the row spacing; therefore, this type of header needs to be equipped with guards and dividers of different sizes. After adjusting the corresponding header row spacing to harvest corn with different row spacing, the corresponding guards and dividers need to be replaced.

[0007] The ear-picking box on the header and ear-picking frame is a certain distance from the stirring base plate so that it does not collide with the stirring base plate when the header and ear-picking frame rotates. A thin iron plate is installed on the ear-picking box, with the other end on the stirring base plate, so that there is no gap between the ear-picking box and the stirring base plate.

[0008] Figure 1 This is an outline drawing of the present invention. Figure 2 This is a schematic diagram of the mechanical transmission of the present invention. Figure 3 This is a schematic diagram of the rotating structure of the picking box frame of the present invention. Detailed Implementation Plan

[0009] This implementation uses a five-row adjustable header as an example, such as... Figure 1 , Figure 2 , Figure 3 As shown, iron plates are uniformly and linearly welded on both sides of the cutting platform support beam. Stabilizing nails are welded to the center of the symmetrical iron plates of the support beam. The center stabilizing nail is not welded at position 3 of the picking box frame. Four holes are drilled in the iron plate to match the size of the four holes on the picking box frame, and then tightened with screws. Four circular holes are drilled in the iron plate with the stabilizing nail as the center. The size of the holes matches the size of the four holes on the picking box frame. One hole is drilled in the center of each of the four holes on the picking frames 1, 2, 4, and 5 to match the stabilizing nail. All four picking boxes are tightened with screws.

[0010] The main power unit is connected to chain 6, chain teeth 7, and shaft 8. Shaft 8 is fixed on two bearings and bearing seats on the header frame. Shaft 8 is connected to shaft 13, which is fixed on the two bearings and bearing seats on the header frame, via chain teeth 9 and chain 10. Shaft 13 is connected to transmission box 15 via universal joint drive shaft 14 and shaft 32. Transmission box 15 is connected to the picking box on the picking frame 1. Shaft 8 is connected to the stirring chain teeth via chain teeth 11 and chain 12, causing the stirring chain to rotate. Shaft 13 is connected to the picking box on the picking box frame 2 via universal joint drive shaft 16, shaft 17, and transmission box 18 to achieve operation. Shaft 17 is connected to the picking box on the picking box frame 2 via universal joint drive shaft 19, shaft 20, and transmission box 21. The picking boxes on the picking box frame 3 are connected to each other to achieve rotation; the main power is connected to the shaft 24 through chain 22 and chain teeth 23. The shaft 24 is fixed to the header frame by two bearings and bearing seats. The shaft 24 is connected to the shaft 27 through chain teeth 25, chain 26, and shaft 27. The shaft 27 is fixed to the header frame by two bearings and bearing seats. The shaft 27 is connected to the picking boxes on the header frame 4 through universal joint drive shaft 28, shaft 33, and transmission box 29 to rotate; the shaft 33 is connected to the picking boxes on the picking box frame 5 through universal joint drive shaft 30, shaft 31, and transmission box 34 to rotate; when the transmission box is connected to the picking boxes on the picking box frame, it should not come into contact with the stirring base plate.

[0011] The guards on both sides of the header are fixed to the ear-picking box frame. The dividers on both sides are connected to the guards with pins. The sizes of other guards and dividers are matched with different sizes depending on the row spacing. Therefore, this type of header needs to be matched with guards and dividers of different sizes. After adjusting the corresponding header row spacing for harvesting corn with different row spacing, the corresponding guards and dividers need to be replaced.

[0012] The ear-picking box on the header is a certain distance from the stirring base plate so that it does not collide with the stirring base plate when the header is rotating. A thin iron plate is installed on the ear-picking box, with the other end on the stirring base plate, so that there is no gap between the ear-picking box and the stirring base plate on the header.

[0013] When adjusting the row spacing, loosen the screws on the header picker frame and the header support beam plate, manually adjust the required row spacing, tighten the screws, replace with the matching guard and divider, and you can start working.

[0014] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
