Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and specifically relates to a pick-up baling and wrapping machine with a leveling function for continuous operation on sloping land. Background Art

[0002] In recent years, with the rapid development of the livestock and poultry breeding industry, the demand for forage has increased rapidly. According to statistics, the forage production in China has increased from 54.65 million tons in 2017 to 76.88 million tons in 2021. However, due to topographical and geomorphic restrictions, the research and development of mechanized harvesting technologies and equipment for forage in hilly and mountainous areas are the key to the sustainable development of China's forage industry, especially the forage pick-up baling and wrapping technology in hilly and mountainous areas.

[0003] At present, foreign pick-up baling and wrapping machines have a high degree of automation and stable performance. However, they are mainly applicable to harvesting under large-scale forage planting, and the models are mainly large-scale operation machines with high costs, and they are not suitable for working conditions such as hilly and mountainous areas, sloping land, and small terraced fields in China.

[0004] Although there are small pick-up baling and wrapping machines in China that can operate in small plots, they do not have a leveling function and can only operate on flat ground conditions, and are not suitable for operating in complex environments such as hilly and mountainous areas and sloping land. The main problems are as follows:

[0005] (1) High missed picking rate and easy damage of spring teeth. The profiling function of the pick-up of the existing round baler is simple, and its profiling ability on hilly and mountainous land is not strong, resulting in too high a missed picking rate, and local protrusions on the ground will also cause deformation of the spring teeth of the pick-up.

[0006] (2) Poor dust removal effect. The dust removal of the existing round baler only enters the auger with mesh holes on the outer shell together with the picked forage and dust and stirs it, and the dust is thrown out through the mesh holes on the outer shell of the auger. However, the diameter of the auger is small, and a large amount of straw enters the baling chamber before being thoroughly cleaned, and the dust removal is not thorough.

[0007] (3) Easy falling of bales. When the existing round bale wrapper operates on hilly and mountainous land, the fuselage cannot maintain a horizontal state, resulting in the bale not rotating in the horizontal plane during wrapping, and it is very easy to cause the bale to fall.

[0008] (4) Easy rolling of bales when they land. The bales output by the existing round baler and round bale wrapper are placed horizontally on the ground. In hilly and mountainous areas, the horizontally placed bales will roll down the slope to the lower place, easily causing the bales to deform or scatter.

[0009] Therefore, it is necessary to design a pick-up baling and wrapping machine with a leveling function for continuous operation on sloping land to solve the above technical problems. Summary of the Invention

[0036] The working principle of the present invention:

[0037] When the pick-up baling and wrapping integrated machine is working, the towing device 7 is connected to the tractor, and the power of the whole machine is provided by the tractor PTO. The bale pressing device 6 compresses the forage laid in the field, and then the pick-up 5 picks it up and sends it into the crushing and conveying device 3 for crushing. The crushed forage enters the conveying auger 0303 and is conveyed to one side, and then is thrown into the dust collector 10 by the throwing blade 0307. While being conveyed, dust removal of the conveying auger and the throwing cylinder is carried out respectively. After the forage is thrown into the dust collector, it falls into the storage bin 9 after the third dust removal. A feeding device 20 is provided at the bottom of the storage bin 9 to intermittently feed the forage into the baling chamber 14 for baling operation. After the baling is completed, the feeding operation stops and the net wrapping operation is carried out. After the net wrapping operation is completed, the rear hatch of the baling chamber 14 is opened, and the bale rolls onto the wrapping device 17 along the bale guiding device. The baling chamber 4 closes the hatch, and the feeding device 20 and the wrapping device 17 work. After the wrapping is completed, the wrapping device 17 tilts backward, and the bale rolls to the field and stands upright through the bale aligning device 18. When operating on a slope, the wrapping leveling device 16 adjusts the wrapping device 17 to be horizontal to prevent the bale from falling, and the falling material recycling device 19 recovers the scattered materials during the operation into the conveying auger 0303.

[0038] When the pick-up leveling device 4 is working, the ground condition detection sensor 0404 detects the ground condition in front of the pick-up. If the terrain is flat, the pick-up lifting cylinder 0403 does not work, and the universal profiling wheel 0405 performs profiling work. If the ground is uneven, the control system 11 controls the pick-up lifting cylinder 0403 to work, and the pick-up 5 can be adjusted to a suitable position for operation.

[0039] When the bale guiding device 15 is working, the inclination sensor 1605 transmits the measured data to the control system 11. The control system 11 controls the winding film device lifting oil cylinder 1507 to adjust the winding film device 17 to an appropriate height. The rear door of the bale chamber 14 is opened, the guiding fixed frame 1502 drops, and both the guiding frame angle adjusting rod 1506 and the guiding frame length adjusting rod 1508 are retracted to the shortest; when the winding film device lifting oil cylinder 1507 contracts, the guiding front connecting rod 1505 rotates upward, and the winding film device 17 moves backward and upward respectively. The guiding frame length adjusting rod 1508 moves upward, the guiding fixed frame 1502 rotates upward, the guiding frame length adjusting rod 1508 moves upward to control the extension of the guiding movable frame 1501. On the contrary, when the winding film device lifting oil cylinder 1507 extends, the winding film device 17 moves forward and downward respectively, the guiding front connecting rod 1505 rotates downward, and the guiding movable frame 1501 contracts; during the lifting and lowering process of the winding film device 17, the positions of the guiding fixed frame 1502 and the guiding movable frame 1501 change accordingly, so that the bale can smoothly fall onto the winding film device 17; when the rear door of the bale chamber 14 is closed, the guiding frame lifting rod 1503 acts on the guiding frame lifting plate 1504, the guiding fixed frame 1502 will be lifted, and both the guiding frame angle adjusting rod 1506 and the guiding frame length adjusting rod 1508 extend to leave enough working space for the winding film device 17 to avoid interference during the winding film operation.

[0040] When the winding film leveling device 16 is working, the inclination sensor 1605 detects the inclination angles of the winding film device 17 in two directions and transmits them to the control system 11. The control system 11 adjusts the winding film device 17 to a horizontal position by controlling the winding film left - right leveling oil cylinder 1602 and the winding film front - rear leveling oil cylinder 1604.

[0041] When the bale straightening device 18 is working, the ground clearance sensor 1804 detects the ground clearances on both sides of the winding film device 17. The control system 11 controls the winding film left - right leveling oil cylinder 1602 to adjust the winding film device 17 to be parallel to the ground, controls the winding film device lifting oil cylinder 1507 to adjust the winding film device 17 to a certain height, and then the winding film device 17 discharges the bale. The bale rolls onto the ground along the bale guiding rod 1801 and the bale straightening rod 1803.
