DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figures 1 to 4 The present invention discloses a corn harvester grain separating device with adjustable gap, comprising:

[0037] When in use, the device is installed on a frame, and the frame is used to connect the device to a corn harvester, and the frame is located at the front end of the corn harvester in the traveling direction. Subsequently, the corn is separated and harvested by the device. When the size of the separation gap needs to be adjusted, the gap adjustment mechanism 4 drives the middle grain divider 1 and the end grain divider 2 toward or away from the fixed grain divider 7, thereby adjusting the separation gap, thereby enhancing the adaptability during corn harvesting, reducing corn harvest losses, and improving economic benefits.

[0038] The fixed crop divider rear end 6 of the fixed crop divider 7 is fixed to the crop divider fixing plate by welding, and the crop divider fixing plate is fixedly connected to the frame.

[0039] Further optimizing the scheme, the gap adjustment mechanism 4 includes a translation driving structure 10, the translation driving structure 10 is arranged on the frame, and the translation driving structure 10 is arranged corresponding to the fixed crop divider 7;

[0040] One end of the translation driving structure 10 is drivingly connected to a telescopic cylinder assembly 9;

[0041] The other end of the translation driving structure 10 is drivingly connected to a driving plate 14 , and the driving plate 14 is drivingly connected to the corresponding middle crop divider 1 or end crop divider 2 through the adjustment structure 8 .

[0042] Further optimizing the scheme, the translation driving structure 10 includes a main driving rotating plate 12, one end of the main driving rotating plate 12 is rotatably arranged on the frame through a rotating shaft, and the other end of the main driving rotating plate 12 is hinged to the middle of the driving plate 14;

[0043] The main driving rotating plate 12 is transmission-connected to the telescopic oil cylinder assembly 9 .

[0044] According to a further optimized solution, one end of a crank arm bracket 13 is fixedly connected to the middle of the main driving rotating plate 12 , and the other end of the crank arm bracket 13 is drivingly connected to the telescopic cylinder assembly 9 .

[0045] According to a further optimized solution, the telescopic cylinder assembly 9 includes a telescopic part, a movable end of the telescopic part is hinged to the other end of the crank arm bracket 13, and a fixed end of the telescopic part is hinged to a mounting frame 902, which is fixed to the frame.

[0046] According to a further optimized solution, the telescopic part includes a telescopic cylinder 901 , one end of which is hinged to an end of the crank arm bracket 13 away from the main driving rotating plate 12 , and the other end of the telescopic cylinder 901 is hinged to the mounting frame 902 .

[0047] According to a further optimization scheme, the adjustment structure 8 includes a driving rotating plate 18, one end of which is hinged to the driving plate 14, and the other end of the driving rotating plate 18 is transmission-connected with a translation structure, which is connected to the rear end 3 of the end crop divider 2 or the rear end 5 of the middle crop divider 1 of the corresponding end crop divider 2.

[0049] The top end of the rotating shaft connected to the frame rotation is fixedly connected to the second corner of the triangular rotating plate 20, and the bottom end of the rotating shaft fixedly connected to the second corner of the triangular rotating plate 20 close to the driving plate 14 is fixedly connected to the end of the corresponding driving rotating plate 18 away from the driving plate 14;

[0050] A connecting rod 16 is hinged between the two triangular rotating plates 20 , and an end of the connecting rod 16 is hinged to the third corner of the corresponding triangular rotating plate 20 .

[0051] When in use, one end of the mounting frame 902 is fixed to the frame, and the other end is hinged to the fixed end of the telescopic cylinder 901. The telescopic end of the telescopic cylinder 901 is hinged to the end of the crank arm bracket 13, and the other end of the crank arm bracket 13 is fixedly connected to the middle part of the main driving rotating plate 12.

The angle rotating plate 20 rotates with its second angle as the rotation axis. The two triangular rotating plates 20 located in the same translation structure are connected together by a connecting rod 16. When one of the triangular rotating plates 20 rotates with the second angle as the rotation axis, under the action of the connecting rod 16, the other triangular rotating plate 20 also rotates with the second angle as the axis. At this time, the first angles of the two triangular rotating plates 20 will drive the crop divider fixing plate 15 hinged thereto to perform translational movement. The crop divider fixing plate 15 is used to be fixedly connected to the corresponding intermediate crop divider 1 or end crop divider 2, so that the intermediate crop divider 1 and the end crop divider 2 located on the same side of the fixed crop divider 7 can move at the same time to change the crop divider gap. Since the adjustment structures 8 located on both sides of the translation drive structure 10 are symmetrically arranged, the crop divider gap can be increased or decreased at the same time to enhance the adaptability during corn harvesting, reduce corn harvest losses, and improve economic benefits.
