Description

Technical Field

[0001] The invention belongs to the technical field of farmland residual film recovery in agricultural machinery, and specifically relates to a residual film recovery roll packaging mechanism, which is used for integrated operations of farmland residual film recovery and packaging. Background Art

[0002] With the widespread application of mulching technology in various regions for the promotion and use of a variety of crops, mechanized residual film recovery has become an inevitable trend. Although mulching cultivation technology has the functions of warming, moisture conservation, drought resistance and promoting root development, it can greatly increase crop yields and shorten the growth period. However, agricultural mulch needs to be recovered in a timely and effective manner, otherwise it will cause environmental pollution, soil compaction and degradation. Although there are degradable mulch films available for selection, the promotion and use of degradable mulch films is limited. For the cleaning of residual film in farmland, it still needs to rely on a large amount of manpower and material resources, with high labor costs and low work efficiency. Mechanized residual film recovery is an effective means to solve the problem of residual film pollution. In addition, the residual film recovered by existing agricultural mulch film recovery machinery is mostly collected into strips and ridges, or put into the film collection box to be stacked at a designated location, and it is also necessary to load and transport it manually or mechanically. The residual film collected in strips, ridges and piles is inconvenient to stack. At the same time, the residual film piled up in the field will occupy a large area of ​​land. If there is a strong wind, some of the residual film will be blown everywhere, causing secondary pollution to the environment. At present, many scholars have studied various types of residual film recycling machines, but most of them are independent residual film recycling machines. During the recycling process, the residual film is seriously entangled with the straw, and it is difficult to remove the film. Therefore, the clean-up rate is low and the effect is not obvious. Moreover, every time it travels a certain distance, it must stop to unload the film, wasting working hours. In order to solve the problem of residual film recycling, it is urgent to develop efficient residual film recycling and packaging products with great development prospects. Summary of the invention

The auxiliary film stripping effect is that the friction force of the film pressing roller 2 gives a tensioning force to the residual film, so that the residual film is easier to separate from the picking and conveying device at the front end of the residual film recovery machine, and the residual film packaging belt device 6 is installed at the rotatable rear part of the packaging frame 1 to receive the residual film sent by the conveyor belt 3 and recycle the residual film for packaging, the transmission mechanism 4 is used to drive the conveyor belt 3 and the residual film packaging belt device 6, and the hydraulic cylinder 5 is installed on the top of the packaging frame 1 to rotate and open the rotatable rear part of the packaging frame 1.

[0031] like Figure 2As shown, the baling machine frame 1 includes two fixed plates 101, two movable plates 102, a connecting rod 103, two hinged shaft connecting plates 104, a hinged shaft 105, a hydraulic cylinder rear seat rod 106, and a hydraulic cylinder front swing rod 107; the two fixed plates 101 are symmetrically connected by the connecting rod 103 to form the fixed front part of the baling machine frame 1, the two movable plates 102 are symmetrically connected by the connecting rod 103 to form the rotatable rear part of the baling machine frame 1, the two hinged shaft connecting plates 104 are respectively fixed to the front upper ends of the two movable plates 102, the two hinged shaft connecting plates 104 and the two fixed plates 101 are respectively hinged by hinged shafts 105, the hydraulic cylinder rear seat rod 106 is fixed to the upper ends of the two fixed plates 101, and the hydraulic cylinder front swing rod 107 is fixed to the upper connecting rod 103 connecting the two movable plates 102.

Figure 7 shown.

[0038] When the residual film packaging tape device 6 described in this embodiment is working, the chain-net type film rolling packaging tape 604 is driven to rotate under the rotation of the transmission mechanism 4, and the round bale of recycled residual film is wrapped around the chain-net type film rolling packaging tape 604, and continues to increase, and the center of gravity moves upward to complete the film rolling operation.

[0039] When the residual film recovery roll packaging mechanism described in this embodiment is unloading film, under the action of the hydraulic cylinder 5, the rotatable rear part of the packaging frame 1 rotates around the hinge shaft 105, and the residual film roll in the residual film packaging belt device 6 rolls out, completing the residual film roll unloading operation.

[0040] The residual film recovery and rolling film packaging mechanism described in this embodiment can complete multiple tasks in one operation, improve the working efficiency, have the advantages of simple structure and low manufacturing cost, and can meet the agronomic requirements of mechanized film collection and packaging. The structure design is reasonable and compact, easy to use, and provides a solution to the secondary pollution easily caused by the stacking of residual film in farmland.
