Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural baling equipment, in particular to a chopping type feeding structure and a baling machine. Background Art
[0002] The baler is a kind of agricultural straw bale baling machine. The baler is connected to the tractor through a traction frame. The power part is connected to the gear box by the rear output power of the tractor, and then the grass pressing roller and the feeding roller are driven by the gear box. The feeding system transports the grass to the forming chamber, and the grass pressing roller in the forming chamber compresses the grass into a cylindrical straw bale. When the density of the straw bale reaches the requirement, the baler wraps the net. After the wrapping is completed, the rear bin opens the straw bale and rolls to the ground through the unloading rack. In order to better improve production efficiency and increase the density of straw bales, a cutting device is added to the feeding system to cut the straw, thereby reducing the secondary processing of the straw bale when feeding livestock in the later stage.
[0003] In the prior art, the moving blades in the feeding system are mostly arranged in a spiral, so that the blades of two adjacent moving blades move inconsistently, and the grass is tilted when it contacts the chopping knife, which may make it impossible to cut it, resulting in a poor overall chopping effect.

[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.
[0033] like Figure 1 and Figure 2 As shown in the figure, the utility model discloses a shredding type feeding structure, including a feeding rotor assembly 1 and a shredding assembly 2, wherein, as shown in the figure, Figure 2 As shown in the figure, the feeding rotor assembly 1 has a knife shaft 11 and a moving knife 12 spirally arranged on the knife shaft 11; the knife shaft 11 rotates under the drive of an external force, thereby driving the moving knife 12 to rotate backward, so that the grass picked up from the picker is transported backward. The chopping assembly 2 is arranged in parallel with the feeding rotor assembly 1, and has a chopping knife that can be inserted into the cutting slot of the moving knife 12; as shown in the figure Figure 2 As shown in FIG. 1 , the chopping knife has not entered the movable knife 12. When the chopping knife enters the gap of the movable knife 12 under the drive of an external force, the grass can be cut. Figure 3 and Figure 4 As shown in FIG. 1 , the movable knife 12 has blades 121 arranged in parallel and in pairs, and the chopping knife performs cutting between the two blades 121 .
[0034] In the above embodiment, the blades 121 are arranged in pairs on the movable knife 12, and the chopping knife is arranged between the two blades 121. When a pair of blades 121 pass through the two sides of the chopping knife at the same time, the grass is vertical when it contacts the chopping knife. Compared with the inclined grass in the prior art, the grass can be cut better.
[0035] Alternatively, if Figure 4 As shown in , the movable knife 12 has a knife seat 122, the inner wall of the knife seat 122 is arc-shaped, and a radially protruding raised key 1221 is provided on the inner wall of the knife seat 122. In the embodiment of the utility model, a plurality of knife seats 122 can be provided, and the plurality of knife seats 122 are assembled to form a complete circular structure, and the fixed installation with the knife shaft 11 is realized by the raised key 1221 provided on the inner wall of the knife seat 122.
[0036] Alternatively, if Figure 2 As shown in the figure, the shredder assembly 2 further includes a rocker arm connected to one end of the shredder blade and a rotating shaft rotatably connected to the other end of the shredder blade. The rocker arm controls the shredder blade to extend between the blades 121 under the drive of an external force. The external force here can be an oil cylinder, which drives the rocker arm to swing, thereby driving the shredder blade to extend between the two blades 121 for cutting.
[0037] Alternatively, if Figure 6 As shown in the figure, it also includes a grass picking assembly 3, which is arranged in parallel with the feeding rotor assembly 1 and has a fixed knife 31 extending between adjacent moving knives 12. Since the moving knives 12 are prone to wrapping grass around the knife shaft 11 during rotation, in the embodiment of the utility model, the fixed knife 31 extends between two adjacent moving knives 12, so that the grass wrapped between the moving knives 12 can be removed when the moving knives 12 rotate; the setting position of the fixed knife 31 is generally set at the rear and upper part of the knife shaft 11, so that the removed grass falls behind the moving knives 12 and is then transported backward.
[0038] Alternatively, if Figure 5 As shown in FIG. 1 , a bottom plate 311 is vertically fixed to the side of the fixed blade 31 facing the rotating direction of the movable blade 12, and the width of the bottom plate 311 is less than the distance between the two movable blades 12. In the embodiment of the utility model, the bottom plate 311 has a guiding function and can also widen the grass picking area of the fixed blade 31 to pick off the grass material entangled on the movable blade 12.
[0039] Alternatively, if Figure 5 As shown in , the grass cutting component 3 also has a grass cutting knife 32 arranged in parallel with the fixed knife 31. The grass cutting knife 32 corresponds to the center of the two blades 121 on the movable knife 12, and is used to remove the grass entangled between the two blades 121. It should be pointed out here that the grass cutting knife 32 and the fixed knife 31 can be fixed on the knife sleeve in parallel. Since the distance between the two blades 121 on the movable knife 12 is small, it is also easy to entangle the grass. Therefore, by extending the grass cutting knife 32 between the two blades 121, the grass between the blades 121 can be cut off to prevent the blades 121 from being entangled with grass. In the embodiment of the utility model, the front end of the grass cutting knife 32 has an arc surface 321. The arc surface 321 and the groove between the blades 121 are concentric circle structures, and the gap between the two is 3-5mm. Through this arrangement, the reliability of grass cutting can be improved, so that the resistance of the chopping knife when cutting grass is smaller.
[0040] Alternatively, if Figure 6As shown in the figure, it also includes a feeding channel 4 arranged at the lower side of the feeding rotor assembly 1, and the feeding channel 4 has a parallel rib plate 41. In the embodiment of the utility model, part of the cut grass falls directly into the feeding channel 4, and the other part is cut off by the fixed knife 31 above; by setting the rib plate 41 on the bottom plate 311 of the feeding channel 4, the resistance of the feeding grass and the bottom surface of the feeding channel 4 can be reduced, so that the grass on the rib plate 41 can be brought into the molding chamber more easily.
[0041] Alternatively, if Figure 1 As shown in the figure, the feeding channel 4 and both sides of the feeding rotor assembly 1 are also provided with an auger roller 5 for conveying grass toward the middle. By rotating the auger, the grass can be fed into the feeding rotor assembly 1, thereby improving the stability and reliability of grass baling.
[0042] In an embodiment of the present invention, a baler is also provided, comprising any one of the above-mentioned shredding type feeding structures.
[0043] Application scenario of an exemplary embodiment:
[0044] like Figures 1 to 6 As shown, when the grass is fed, the grass is transported toward the molding chamber by the rotation of the feeding rotor assembly 1 and the rotation of the movable knife 12; at the same time, the chopping knife is extended between the blades 121 under the drive of the oil cylinder, so that the grass is sheared vertically with the chopping knife under the drive of the movable knife 12 to achieve the cutting of the grass, and at the same time, the fixed knife 31 and the grass cutting knife 32 arranged on the upper rear side of the movable knife 12 can cut off the grass wound on the knife shaft 11 between the movable knives 12 and the grass wound between the blades 121, and then the grass is fed from the feeding channel 4 into the molding chamber under the rotation of the movable knife 12.
