[0002] The cutter bar of a silage harvester is a forage harvesting machine. In order to ensure convenient gathering and orderly feeding of straws during harvesting, the presence of a grain gathering device is crucial. Currently, the front-end structure of the existing grain gathering device is symmetric left and right and cannot move, making it unable to handle problems that occur during crop harvesting, such as fixed obstacles and harvesting vehicles in some large farmlands. If it collides and is damaged, it will affect the harvesting efficiency. Moreover, the existing grain gathering device is not convenient for folding, storing, and transporting. Therefore, there is an urgent need to design an anti-collision flexible grain gathering device that can adapt to different harvesting environments in the field and is convenient for folding, storing, and transporting.

Detailed Implementation Modes

[0018] The present utility model will be further described below in conjunction with the accompanying drawings and by way of examples.

[0019] An anti-collision flexible header harvester includes a left header side fork straight pipe 2-1, a right header side fork straight pipe 2-2, a left header side fork pipe 3-1, a right header side fork pipe 3-2, a first rubber hose 5-1, a second rubber hose 5-2, and a header middle support 6. The left header side fork straight pipe 2-1, the left header side fork pipe 3-1, the first rubber hose 5-1, the header middle support 6, the second rubber hose 5-2, the right header side fork pipe 3-2, and the right header side fork straight pipe 2-2 are connected in sequence; the header middle support 6 is arranged at the middle position of the cutting table. The left header side fork straight pipe 2-1, the left header side fork pipe 3-1, and the first rubber hose 5-1 are arranged on the left side of the header middle support 6, and the second rubber hose 5-2, the right header side fork pipe 3-2, and the right header side fork straight pipe 2-2 are arranged on the right side of the header middle support 6. The structures on the left and right sides of the header middle support 6 are symmetrical along the central axis of the header middle support 6; a link fixing plug 7, a link, a tension spring 10, a loose joint bolt 11, and a loose joint bolt fixing plug 12 are arranged inside the left header side fork straight pipe 2-1. The link fixing plug 7 is fixed on the left header side fork pipe 3-1. The link fixing plug 7 is connected to one end of the tension spring 10 through the link. The other end of the tension spring 10 is connected to the loose joint bolt fixing plug 12 through the loose joint bolt 11. One end of the left header side fork straight pipe 2-1 is movably connected to the left header side fork pipe 3-1, and the other end is fixedly connected to the loose joint bolt fixing plug 12.

[0020] The number of the links is two, namely a first link 9-1 and a second link 9-2. The first link 9-1 and the second link 9-2 are arranged in a cross shape. The first link 9-1 is connected to the link fixing plug 7, and the second link 9-2 is connected to one end of the tension spring 10.

[0021] The first link 9-1 is hinged to the link fixing plug 7 through a hinge shaft 8, and the hinge shaft 8 longitudinally penetrates the first link 9-1.

[0022] Left header caps 1-1 and right header caps 1-2 are respectively arranged at the ends of the left header side fork straight pipe 2-1 and the right header side fork straight pipe 2-2.

[0023] Left support positioning plates 4-1 and right support positioning plates 4-2 are respectively arranged on the left header side fork pipe 3-1 and the right header side fork pipe 3-2. The left header side fork pipe 3-1 and the right header side fork pipe 3-2 are respectively fixed on the table tools on both sides of the double-ridge cutting table through the left support positioning plates 4-1 and the right support positioning plates 4-2. When the double-ridge cutting table folds, the left header side fork pipe 3-1 and the right header side fork pipe 3-2 can fold along with it due to the connection of the first rubber hose 5-1 and the second rubber hose 5-2.

[0024] A nut is welded inside the knuckle bolt fixing plug 12.

[0025] The left header side fork straight pipe 2-1, the right header side fork straight pipe 2-2, the left header side fork pipe 3-1, the right header side fork pipe 3-2 and the header middle support 6 all adopt a hollow design, reducing the suspension weight.

[0026] In this embodiment, referring to the appendix Figures 1-3 , the header middle support 6 is fixed at the middle position of the cutter bar, and each component is symmetric along the central axis of the header middle support 6. All parts except the rubber hose 1 5-1, the rubber hose 2 5-2 and the tension spring 10 are made of alloy structural steel, with high structural strength and not easily damaged. Main components such as the left header side fork straight pipe 2-1, the right header side fork straight pipe 2-2, the left header side fork pipe 3-1, the right header side fork pipe 3-2 and the header middle support 6 all adopt a hollow design, reducing the suspension weight.

[0027] The link fixing plug 7 and the knuckle bolt fixing plug 12 are respectively inlaid and fixed at the ends of the left header side fork pipe 3-1 and the left header side fork straight pipe 2-1 to provide a fixed connection component for the link and the knuckle bolt 11. The two links are arranged in a cross shape to limit the freedom degree of the end left header side fork straight pipe; the knuckle bolt 11 is a component with adjustable spacing, and a nut is welded inside the knuckle bolt fixing plug 12, which can make the tension spring 10 have a pre-tightening force, and also play a role in limiting the freedom degree of the left header side fork straight pipe on the premise of ensuring that the tension spring does not fall off.

[0028] The tension spring 10 has high flexibility. When harvesting crops and encountering hard objects, under the action of each component, the tension spring 10 avoids obstacles by changing direction, avoiding collisions. During transportation, the foldable cutter bar can greatly reduce the storage space, and the flexible header is the same.

[0029] As Figure 1 、 4 shown, Figure 1 is the unfolded state of the header when working; when the cutter bar is idle, the tools on both sides of the double-ridge cutter bar will fold up from bottom to top towards the central axis of the header middle support 6. Since the left support positioning plate 4-1 and the right support positioning plate 4-2 are fixed on the tools on both sides, the left header side fork pipe 3-1 and the right header side fork pipe 3-2 will also fold up from bottom to top along with the tools, as Figure 4 shown. However, the center distance of the tools of the cutter bar remains unchanged, so the ridge distance also remains unchanged. After folding, the longitudinal space is large, and the left header side fork straight pipe 2-1 and the right header side fork straight pipe 2-2 can be flexibly adjusted during storage, greatly reducing the storage space.

[0030] As Figure 2As shown in the figure, it is the internal view of the straight pipe of the left grain gathering device's side fork. The first link 9-1 is longitudinally penetrated by the hinge shaft 8. The first link 9-1 is hinged to the link fixing plug 7, which not only prevents the first link 9-1 from shaking up and down longitudinally, but also enables the first link 9-1 to move horizontally. The first link 9-1 is cross-matched with the second link 9-2, the second link 9-2 is cross-matched with the tension spring 10, and finally the tension spring 10 is cross-matched with the eye bolt 11. A nut is welded inside the eye bolt fixing plug 12, enabling the eye bolt 11 to adjust the spacing by turning it clockwise or counterclockwise. Both the eye bolt 11 and the eye bolt fixing plug 12 are installed at the end of the straight pipe of the left grain gathering device's side fork, forming a flexible grain gathering device's movable straight pipe structure.

[0031] The left grain gathering device's side fork straight pipe 2-1 and the right grain gathering device's side fork straight pipe 2-2 have the same structure.

[0032] In order to meet the necessary device of the grain gathering device for the foldable silage harvester header, the present utility model designs an anti-collision flexible grain gathering device on the basis of the original fixed row spacing. The end of the side fork pipe of the grain gathering device is provided with a straight pipe of the side fork of the grain gathering device, and the cooperation of each internal component can achieve the effect of flexible direction change, greatly reducing the occurrence of collision damage.
