[0042] It should be noted that, without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.

[0043] As Figures 1 to 6 shown, the present utility model discloses a feeding device, which includes a conveying bottom plate 1, a spiral roller 2, and a weed removing rake 3; specifically as Figure 1 and Figure 2As shown in the figure, the conveying bottom plate 1 serves as the bottom plate of the feeding mechanism. When the spiral roller 2 rotates counterclockwise, the material is conveyed backward between the bottom of the spiral roller 2 and the conveying bottom plate 1. The connection between the conveying bottom plate 1 and the picking-up mechanism here refers to the connection with the bottom plate of the picking-up mechanism. The picking-up mechanism is a prior art and will not be introduced in detail here. The spiral roller 2 is rotatably arranged above the conveying bottom plate 1 and is used to convey the material along the conveying bottom plate 1 to the rear. Of course, it should be noted here that in the embodiment of the present invention, the material refers to crops such as forage or straw for baling and conveying, which will be collectively referred to as material in the following text. One end of the weed removing rake 3 is fixedly connected, and the other end extends into the gap of the spiral roller 2 and is used for removing the material wound on the spiral roller 2. Since the spiral roller 2 is prone to winding grass during rotation, through the arrangement of the weed removing rake 3, the material on the spiral roller 2 is removed to reduce the jamming problem. Please continue to refer to Figure 1 , in the embodiment of the present invention, the weed removing rake 3 is inclined and forms a trumpet-shaped channel with a smaller front and a larger rear with the conveying bottom plate 1. Through the setting of this structural form, it can make the material have a larger space during the backward conveying process, thereby reducing the occurrence of blockage.

[0044] In the above embodiment, through the arrangement of the weed removing rake 3, the material wound on the spiral roller 2 can be removed, thereby reducing the occurrence of the jamming problem. And through the inclined setting of the weed removing rake 3, the space for the material to enter can be increased, thereby reducing the material blockage phenomenon generated during the pushing process of the material. Compared with the prior art, the problems of jamming and material blockage are reduced.

[0045] Optionally, as Figure 3 shown in the figure, the conveying bottom plate 1 is provided with ribs 11. The ribs 11 protrude from the upper surface of the conveying bottom plate 1 and extend along the material conveying direction. A plurality of ribs 11 are evenly distributed at intervals in the width direction of the conveying bottom plate 1. Through the arrangement of the ribs 11, the material is lifted by the ribs 11 during the conveying process, reducing the contact area between the material and the conveying bottom plate 1, thereby reducing the friction force and improving the feeding ability of the material.

[0046] Optionally, as Figure 3 shown in the figure, the spiral roller 2 includes an input shaft 21, a transmission mechanism 22 and star-shaped teeth 23. In the embodiment of the present invention, the input shaft 21 is rotatably arranged. When specifically installed, bearing seats can be arranged on both sides of the input shaft 21 to realize the rotation of the input shaft 21. The transmission mechanism 22 is arranged at at least one end of the input shaft 21 and is used to drive the input shaft 21 to rotate under the drive of an external force; the star-shaped teeth 23 are fixed on the input shaft 21 and are evenly distributed along the axial direction of the input shaft 21. In this way, the external force can be a chain connected to the gearbox, and the chain is connected to the sprocket 221, thereby driving the rotation of the input shaft 21.

[0047] Optionally, as Figure 2 andFigure 3 As shown, the star-shaped teeth 23 are arranged in a spiral form on the input shaft 21, and the ribs 11 are arranged staggered with the star-shaped teeth 23. Through the spiral shape of the star-shaped teeth 23 Uniformly distributed , a linear contact between the star-shaped teeth 23 and the materials on the conveying bottom plate 1 is avoided, the risk of grass jamming is reduced, and through the setting of the star-shaped teeth 23, the space between the star-shaped teeth 23 is larger, and more forage is conveyed per revolution. As Figure 2 shown, through the structural design of the staggered arrangement of the star-shaped teeth 23 and the ribs 11, the forage is lifted, and the distance between the star-shaped teeth 23 and the forage is reduced, thereby improving the grasping force of the star-shaped teeth 23 and further improving the feeding capacity.

[0048] Optionally, as Figure 3 and Figure 4 shown, each star-shaped tooth 23 passes through two parallel and spaced tooth plates. The weed removing rake 3 includes an in-tooth weed removing knife 31 corresponding to the gap between the two tooth plates and an inter-tooth weed removing knife 32 corresponding to the gap between two adjacent star-shaped teeth 23. In this way, through the setting of the two forms of weed removing knives, the reliability of weed removal can be improved, and the jamming phenomenon can be further avoided.

[0049] Optionally, as Figure 5 shown, the transmission mechanism 22 includes a sprocket 221, a first flange 222, a second flange 223 and a flat key 224 arranged on the sprocket 221; specifically, a first flange 222 is fixedly connected to one side of the sprocket 221, and the first flange 222 is sleeved on the input shaft 21; it should be noted here that the first flange 222 and the sprocket 221 can be integrally cast or connected together by welding or screwing. The second flange 223 is sleeved on the input shaft 21 and is oppositely connected to the first flange 222. The second flange 223 has a keyway corresponding to the input shaft 21; it should be noted here that the keyway is arranged on the inner wall of the second flange 223 and the surface of the input shaft 21, and the flat key 224 is embedded in the keyway. In this way, the second flange 223 can rotate synchronously with the input shaft 21 under the action of the flat key 224 and the keyway. Since the first flange 222 is connected to the second flange 223, the rotation of the sprocket 221 can drive the input shaft 21 to rotate synchronously.

[0050] Optionally, as Figure 6As shown, to improve the reliability of the sprocket 221 and avoid damage to the sprocket 221 during jamming or overload operation, the first flange 222 and the second flange 223 are connected by safety bolts 225, and the safety bolts 225 are configured to be cut off when the torque is greater than the set value. In this way, when the star teeth 23 jam or operate under overload, the sprocket 221 drives the first flange 222 to rotate relative to the second flange 223, cutting off the safety screw, so that the sprocket 221 drives the first flange 222 to rotate idly around the input shaft 21 to achieve unloading. It should be noted here that those skilled in the art can select the material of the safety bolt 225 according to the required set torque value.

[0051] Optionally, as Figure 6 shown, to prevent jamming when the sprocket 221 and the first flange 222 rotate idly around the input shaft 21, an oil injection nozzle 226 is also provided on the first flange 222 along the radial direction for lubrication between the first flange 222 and the input shaft 21. Of course, it should be noted here that there are various structural forms of the oil injection nozzle 226. For example, a threaded hole can be provided in the radial direction of the first flange 222, and an oil injection port can be installed. Before use, butter or other lubricating oil is injected through the oil injection nozzle 226 to avoid jamming during idling.

[0052] In an embodiment of the present invention, a baler is also provided, including the feeding device according to any one of the above.

[0053] In an embodiment of the present invention, a forage harvester is also provided, including the feeding device according to any one of the above.

[0054] An application scenario of an exemplary embodiment:

[0055] As Figures 1 to 6 shown, after the forage enters the pickup table, the spiral roller 2 rotates counterclockwise, and the forage is conveyed to the rear along the bottom of the spiral roller 2 along the conveying bottom plate 1. The weed removing rake 3 removes the forage wound around the spiral roller 2 and falls onto the conveying bottom plate 1; as the spiral roller 2 rotates continuously, the forage is continuously pushed backward. Through the inclined setting of the weed removing rake 3, a trumpet-shaped channel with a small front and a large rear is formed, and then the pushed-forth forage is conveyed along the Figure 1 lower bottom plate and guide plate shown by the dotted line in to the rear of the punching piston, where it is punched into bales to complete the operation process.
