Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Embodiment 1
[0020] A four-rope feeding and feeding device, as Figure 1 and Figure 2 shown, includes a picking frame 1 and a feeding frame 2. A picking inlet 11 is provided at the front end of the picking frame 1. A picking connection position adapted to be connected and cooperated with a picking device 5 is also provided at the front end of the picking frame 1 corresponding to the picking inlet 11. A picking cavity 12 is provided in the picking frame 1 corresponding to the picking inlet 11. The picking cavity 12 communicates with the picking inlet 11. Forage, straw and other materials picked are fed into the picking cavity 12 through the picking inlet 11. Two sets of auger conveyors 13 are provided in the picking cavity 12. The auger conveyor 13 is an auger conveying device in the prior art. A picking outlet is provided at the position between the two sets of auger conveyors 13 in the picking cavity 12. The two sets of auger conveyors 13 are symmetrically arranged and both convey the materials in the picking cavity 12 to the position between the two auger conveyors 13. The materials in the picking cavity 12 converge towards the picking outlet, facilitating the output of the materials from the picking outlet.
[0021] The feeding frame 2 is connected to the picking frame 1. A feeding cavity 21 is provided inside the feeding frame 2. The feeding cavity 21 communicates with the picking outlet. A feeding inlet is provided on the feeding frame 2 corresponding to the feeding cavity 21. A feeding connection position adapted to be connected and cooperated with a feeding device 6 is provided on the feeding frame 2 corresponding to the feeding inlet. The feeding inlet communicates with the feeding cavity 21. The picking outlet and the feeding inlet are respectively on both sides of the feeding cavity 21, and the picking outlet, the feeding cavity 21 and the feeding inlet form a feeding channel. A feeding mechanism 3 is provided in the feeding cavity 21. The feeding mechanism 3 dials the materials converged at the picking outlet in the picking cavity 12 into the feeding channel, and dials the materials in the feeding channel towards the feeding inlet and the feeding device 6.
[0022] Please refer to Figure 1 and Figure 2, the feeding mechanism 3 is a feeding rotor, which includes a rotor shaft 31 and rotor blades 32. The rotor shaft 31 is installed on the feeding frame 2 and rotates relative to the feeding frame 2. One end of the rotor shaft 31 extends outside the feeding cavity 21. A feeding driving member is provided on the feeding frame 2. The feeding driving member can be a power device such as a driving motor. The acting part of the feeding driving member is connected to the rotor shaft 31 and drives the rotor shaft 31 to rotate. A number of rotor blades 32 are uniformly arranged along the axial direction on the shaft body of the rotor shaft 31 located in the feeding cavity 21. The feeding driving member drives the rotor shaft 31 to rotate, thereby driving each rotor blade 32 to rotate. During the rotation of the rotor blades 32, their ends alternately pass through the feeding cavity 21 and the picking-up cavity 12. Each rotor blade 32 cooperates to dial the material converged at the picking-up outlet in the picking-up cavity 12 into the feeding channel, and dial the material in the feeding channel along the feeding channel towards the feeding port.
[0023] Specifically, the rotor shaft 31 includes a rotor shaft 31 tube and a rotor shaft 31 head. The rotor shaft 31 tube is entirely located in the feeding cavity 21. Rotor shaft 31 heads are provided at both ends of the rotor shaft 31 tube. The rotor shaft 31 tube is coaxial with each rotor shaft 31 head. The rotor shaft 31 head is installed on the feeding frame 2 through a bearing structure and rotates relative to the frame. The acting part of the feeding driving member is connected to one or two rotor shaft 31 heads to drive the rotor shaft 31 tube to rotate. Each rotor blade 32 is distributed on the rotor shaft 31 tube, and each rotor blade 32 is uniformly distributed along the axial direction of the rotor shaft 31 tube.
[0024] As a further implementation of this embodiment, please refer to Figure 1 and Figure 2 , the rotor blade 32 includes an intermediate rotor blade 32, a first rotor blade 32 and a second rotor blade 32. An intermediate rotor blade 32 is provided at the middle position of the rotor shaft 31 tube. The two sides of the intermediate rotor blade 32 on the rotor shaft 31 tube are respectively set as a first installation area and a second installation area. A number of first rotor blades 32 are uniformly distributed along the axial direction of the rotor shaft 31 tube in the first installation area. In the first installation area, from the middle of the rotor shaft 31 tube towards the end, each first rotor blade 32 deflects successively along the circumferential direction and is distributed in a spiral shape. A number of second rotor blades 32 are uniformly distributed along the axial direction of the rotor shaft 31 tube in the second installation area. In the second installation area, from the middle of the rotor shaft 31 tube towards the end, each second rotor blade 32 deflects successively along the circumferential direction and is distributed in a spiral shape. The spiral distribution directions of each second rotor blade 32 are opposite to those of each first rotor. Since each first rotor blade 32 and each second rotor blade 32 are both distributed in a spiral shape and the spiral directions are opposite, at least one V shape is formed by the distribution of each rotor blade 32 on the surface of the rotor shaft 31 tube. The rotor shaft 31 rotates along the direction from the tip of the V shape to the open end, so as to achieve a better material dialing effect.
[0025] Please refer to Figure 1 and Figure 2 , the rotor blade 32 includes a blade plate and feeding teeth. The blade plate is an annular plate, which is sleeved outside the tube of the rotor shaft 31 and connected to the tube of the rotor shaft 31. Feeding teeth are provided on the blade plate. The circumferential deflection of adjacent rotor blades 32 along the tube of the rotor shaft 31 will cause the feeding teeth of adjacent rotor blades 32 to have a position deviation in the circumferential direction of the tube of the rotor shaft 31, thereby finally forming at least one V-shaped structure on the surface of the tube of the rotor shaft 31.
[0026] As a preferred embodiment, at least two feeding teeth are provided on the blade plate, and each feeding tooth is evenly arranged along the circumferential direction around the tube of the rotor shaft 31. Each blade plate is provided with at least two feeding teeth, so that each rotor blade 32 forms at least two groups of V-shaped structures on the surface of the tube of the rotor shaft 31, so that each rotor blade 32 can play a better material feeding effect during the rotation of the rotor shaft 31.
[0027] As a further preferred embodiment, the rotor blade 32 includes two blade plates, both of which are arranged outside the tube of the rotor shaft 31 and there is a gap between the two blade plates, and the feeding teeth on the two blade plates correspond to each other respectively. The rotor blade 32 is formed by two blade plates with opposite surfaces facing each other, which increases the thickness of the rotor blade 32, thereby improving the material feeding effect.
[0028] A grass cleaning mechanism 4 is provided above the feeding port in the feeding cavity 21. The grass cleaning mechanism 4 cooperates with the feeding mechanism 3 and is used to strip the materials such as forage and straw on the rotor blade 32 of the feeding mechanism 3, so as to avoid the influence of the winding of materials such as forage and straw on the feeding mechanism 3 on the normal use of the equipment.
[0029] Please refer to Figure 1 and Figure 2 , the grass cleaning mechanism 4 includes a plurality of grass cleaning knives. The grass cleaning knives are connected to the feeding frame 2. Each grass cleaning knife is located above the feeding port. Each grass cleaning knife is evenly distributed along the direction parallel to the rotor shaft 31. A grass cleaning gap for the rotor blade 32 to pass through is reserved between adjacent grass cleaning knives. In the axial direction of the rotor shaft 31, the grass cleaning knives and the rotor blade 32 are arranged alternately in sequence. The rotation of the rotor shaft 31 drives the rotor blade 32 to periodically pass through the corresponding grass cleaning gap.
[0030] The grass cleaning mechanism 4 is arranged above the feeding port. After each rotor blade 32 of the feeding mechanism 3 cooperates to dial the materials in the feeding channel into the feeding port, the rotor blade 32 rotates upward at the feeding port and passes through the grass cleaning gap. When the rotor blade 32 passes through the grass cleaning gap, the two adjacent grass cleaning knives cooperate to peel off or cut off the materials such as forage and straw carried on the rotor blade 32, so as to avoid the materials being finally wound around the rotor shaft 31 as the rotor shaft 31 rotates.
[0031] The feeding and feeding device of this embodiment is applicable to balers, especially four-string balers. The picking opening of the picking cavity 12 is relatively wide to be suitable for a picking device 5 with a larger width. Two auger conveyors 13 cooperate to converge the materials in the picking cavity 12 to the picking outlet, so as to facilitate the feeding mechanism 3 to dial the materials into the feeding channel and dial them out from the feeding inlet through the feeding channel, thereby improving the feeding effect and feeding efficiency.

The picking device 5 is a picking component used in a four-string baler in the prior art for picking materials such as forage and straw. The feeding device 6 is a feeding component used in a four-string baler in the prior art for transporting and pre-compressing materials such as forage and straw. Both are relatively mature components in the prior art. In this embodiment, the structures of the picking device 5 and the feeding device 6 are not specifically described.
[0034] The picking device 5 is connected at the picking connection position of the picking frame 1 of the feeding device. The picking and discharging end of the picking device 5 communicates with the picking inlet 11 of the picking frame 1. The materials such as forage and straw picked by the picking device 5 are sent into the picking cavity 12 through the picking inlet 11. Two auger conveyors 13 in the picking cavity 12 forcefully converge the materials to the picking outlet; the feeding device 6 is connected at the feeding connection position of the feeding frame 2 of the feeding device. The feeding end of the feeding device 6 communicates with the feeding inlet of the feeding frame 2. The feeding mechanism 3 forcefully dials the materials converged to the picking outlet in the picking cavity 12 into the feeding device 6 through the feeding channel, and the feeding device 6 transports and pre-compresses the materials, and finally realizes the compression, bundling and output of the materials through other components of the four-string baler.
