Description

Technical Field

[0001] The invention relates to the technical field of reed bamboo harvesting, in particular to a reed bamboo harvesting feeding device and a reed bamboo harvesting cutting platform. Background Art

[0002] Phragmites australis has the advantages of fast growth, flood resistance, drought resistance, saline-alkali resistance, disease and insect resistance, etc. It is suitable for planting in non-arable land such as tidal flats, wetlands, saline-alkali land, degraded land, and abandoned mining areas. The yield is 5 to 10 tons per mu. It is widely used in biomass fuel, papermaking and other fields. The scale of planting has become increasingly larger in recent years.

[0003] With the increase in the scale of planting, the improvement of harvesting efficiency is a problem that needs to be solved at present. The existing grass flattening cutter can achieve the harvest of reed, but there is a problem of poor feeding. For example, in the existing patent with patent number 202010184317.0 and patent name "Self-propelled rotary mower and conditioner cutting and conditioning device", a row of cutters are arranged at the front end of the cutter, and a spiral feeding roller is arranged behind the cutter. The cut plants can only be fed in contact with the spiral feeding roller after the cutter moves forward, and the feeding efficiency is low. Since the plants are not fed in time after being cut, some plants cannot be fed after they fall over and cannot contact with the spiral feeding roller, resulting in some plants remaining after harvesting, resulting in low harvesting efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a reed harvesting and feeding device and a reed harvesting and cutting platform, so as to improve the reed feeding effect and thus improve the reed harvesting efficiency.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: a reed harvesting and feeding device comprises a mounting frame, a plurality of rotating disks arranged in a straight line are provided at the front end of the mounting frame, a spacing is provided between two adjacent rotating disks, and the plurality of rotating disks are divided into two symmetrically arranged groups with the center of the front end of the mounting frame, a first driving mechanism for driving the rotating disks to rotate axially is provided on the mounting frame, and the two groups of rotating disks rotate in opposite directions driven by the first driving mechanism; a columnar multi-layer toothed weeding wheel assembly is fixedly installed on the two rotating disks at both ends, a double-layer tower-shaped weeding wheel assembly is fixedly installed on the rotating disks spaced apart from the columnar multi-layer toothed weeding wheel assembly, and a knife disc is fixedly installed on the remaining rotating disks; a columnar spiral toothed lifting roller is rotatably provided on the rear side of the rotating disk, and the length direction of the columnar spiral toothed lifting roller is arranged parallel to the extension direction of the plurality of rotating disks; a double-layer flattening roller assembly is provided on the rear side of the columnar spiral toothed lifting roller, and both the columnar spiral toothed lifting roller and the double-layer flattening roller assembly are transmission-connected to the second driving mechanism.

[0006] The beneficial effect of the present invention is that through the columnar multi-layer toothed weed wheel assembly and the double-layer flattening roller assembly arranged in the same row as the cutter disc, when the reed is cut, it is directly fed to the columnar spiral toothed lifting roller through the columnar multi-layer toothed weed wheel assembly and the double-layer flattening roller assembly, and then flattened and transported by the double-layer flattening roller assembly, thereby improving the feeding effect of the reed harvesting and further improving the reed harvesting efficiency.

[0007] Based on the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the columnar multi-layer toothed grass wheel assembly includes a plurality of annular gear plates arranged at intervals up and down, the plurality of annular gear plates are coaxially arranged, the outer teeth of two adjacent annular gear plates are staggered, the plurality of annular gear plates are fixedly connected by a support frame, and the annular gear plate located at the bottom is fixedly connected to the rotating plate by bolts; the first driving mechanism is arranged vertically above the plurality of annular gear plates, and the output shaft of the first driving mechanism passes through the inner rings of the plurality of annular gear plates in turn and is transmission-connected to the rotating plate, and the rotating plates in the same group are connected by gear transmission.

[0009] The beneficial effect of adopting the above further solution is that the outer teeth of the multi-layered annular gear plates are arranged in a staggered manner, which effectively transports the reeds of different thicknesses backwards, thereby improving the efficiency of transportation and feeding.

[0010] Furthermore, the number of the support frames is four, and the four support frames are fixedly connected in pairs by bolts. Each of the annular gear plates includes two semi-annular gear plates, and the two ends of the semi-annular gear plates are respectively fixedly connected to one of the support frames.

[0011] The beneficial effect of adopting the above-mentioned further scheme is: the annular column structure composed of multiple annular gear plates is divided into two symmetrically arranged semi-annular column structures, and the output shaft of the first drive mechanism is connected with the rotating plate for transmission. It is only necessary to respectively sleeve the semi-annular column structures on the outside of the output shaft of the first drive mechanism, and then fix the two semi-annular column structures with bolts to form an annular column structure, which is convenient for the installation of the columnar multi-layer toothed grass wheel assembly.

[0012] Furthermore, connecting frames are fixedly provided at both ends of the two semi-annular gear plates of the second annular gear plate from bottom to top, and the connecting frames are fixedly connected to the supporting frames by bolts.

[0013] The beneficial effect of adopting the above-mentioned further scheme is as follows: since the annular gear plate located at the bottom needs to be fixedly connected to the rotating plate by bolts, before installation, the second annular gear plate from bottom to top is first disassembled, and when the annular gear plate located at the bottom is connected to the rotating plate, the connecting frame is connected to the supporting frame to provide operating space for the connection between the annular gear plate located at the bottom and the rotating plate.

[0014] Furthermore, it also includes two semi-annular reinforcement frames, both ends of which are fixedly connected to one of the support frames respectively, and the two semi-annular reinforcement frames are spliced ​​to form an annular structure coaxial with the annular gear plate, each of the semi-annular reinforcement frames is fixedly provided with a reinforcement plate, and each of the semi-annular gear plates is connected to one of the reinforcement plates.

[0015] The beneficial effect of adopting the above further solution is that the provision of the semi-annular reinforcement frame and the reinforcement plate can improve the connection strength between the multiple annular gear plates.

[0016] Furthermore, the double-layer tower-shaped grass wheel assembly includes a middle tube, a large gear plate, a small gear plate and a plurality of fixing bolts. The large gear plate and the small gear plate are fixedly sleeved on the middle tube at intervals from bottom to top, and the plurality of fixing bolts pass through the small gear plate and the large gear plate in sequence from top to bottom and are fixedly connected to the rotating plate.

[0017] The beneficial effect of adopting the above further scheme is: the large and small gear plates arranged at intervals above and below can provide effective power for the transportation of intermediate materials. The low double-layer tooth structure can not only effectively transport materials, but also occupy a smaller channel, providing more ample space for the backward transportation of materials.

[0018] Furthermore, the intermediate tube is a rectangular tube.

[0019] The beneficial effect of adopting the above further solution is that the middle tube adopts a rectangular tube, which can increase the torsional resistance of the overall structure.

[0020] Furthermore, the columnar spiral-toothed lifting roller includes a lifting roller body, the lifting roller body is rotatably mounted on the mounting frame, one end of the lifting roller body is transmission-connected to the second driving mechanism, a left spiral sheet and a right spiral sheet are symmetrically fixedly arranged on the lifting roller body, the left spiral sheet and the right spiral sheet are spirally wound around the lifting roller body in opposite spiral directions, and spiral teeth are arranged on the outer sides of the left spiral sheet and the right spiral sheet.

[0021] The beneficial effect of adopting the above further scheme is: providing spiral teeth on the left and right spiral plates spirally wrapped around the lifting roller body in opposite spiral directions can improve the conveying efficiency of the lifting roller, and can also properly convey the material to the middle, reducing the probability of blockage.

[0022] Furthermore, the double-layer flattening roller assembly includes a front flattening roller group and a rear flattening roller group, the front flattening roller group includes a front upper flattening roller and a front lower flattening roller that are meshed with each other, and the rear flattening roller group includes a rear upper flattening roller and a rear lower flattening roller that are meshed with each other, and the front upper flattening roller, the front lower flattening roller, the rear upper flattening roller and the rear lower flattening roller are all connected to the second driving mechanism in transmission.

[0023] The beneficial effect of adopting the above further solution is that the setting of the double-layer flattening structure can improve the flattening effect, thereby improving the transportation efficiency.

[0024] The present invention solves the above technical problem and further provides a reed harvesting header, comprising the reed harvesting and feeding device described above.

[0025] The beneficial effect of adopting the above scheme is: through the columnar multi-layer toothed weed wheel assembly and the double-layer flattening roller assembly arranged in the same row as the cutter disc, when the reed is cut, it is directly fed to the columnar spiral toothed lifting roller through the columnar multi-layer toothed weed wheel assembly and the double-layer flattening roller assembly, and then flattened and transported through the double-layer flattening roller assembly, thereby improving the feeding effect of the reed harvesting and further improving the reed harvesting efficiency.
