Description

Technical Field

[0001] The utility model relates to the technical field of agricultural residual film recovery equipment, in particular to a retracted-tooth type residual film recovery machine. Background Art

[0002] In recent years, the Northwest region has implemented corn planting methods such as full-film double-ridge furrow planting and corn flat-cropping full-film sowing due to its unique geographical restrictions. The film-covered planting area in Gansu Province is 1.8667 million hm 2 , the annual use of ground film exceeds 140,000 tons. Among all kinds of crops planted with ground film, vegetables and corn are the most used, accounting for more than 80% of the planting area covered by ground film. In view of the recycling of ground film in Gansu Province, relevant technicians have carried out a lot of relevant research. The machines developed are mainly miniaturized, and there are few mature and molded products. Due to the complex working conditions of mechanical picking up of waste ground film, ground film, straw, root stubble and soil are mixed together, and it is difficult to separate the film from the root stubble, straw and soil. The ground film and soil bonding of corn planting in the Hexi Irrigation Area of ​​Gansu Province is strong, and it is also necessary to consider the coordination of operations such as returning straw to the field. Ordinary ground film recycling machinery has a high impurity rate and the root stubble is easy to clog the machine. The efficiency of field ground film recycling is low, and recycling is difficult, which increases the labor intensity of farmers.

[0003] CN202110749270.2 discloses a residual film collecting machine, which is provided with a shaking lifting chain tilted upward on the frame behind the film shovel, and the shaking lifting chain transports the ground film shoveled by the film shovel backward while shaking off the soil attached to the ground film. At the same time, a film rolling device is provided on the frame behind the shaking lifting chain to recycle the ground film. Although the shaking lifting chain is provided in this scheme, the ground film can be separated from the soil and the impurity content can be reduced to a certain extent, but the recycling is not thorough and the recycling efficiency is still low. The existing technology cannot solve the above problems. Utility Model Content

[0004] The utility model aims to solve the technical problems existing in the existing residual film recovery machine in recovering ground film, and provides a telescopic tooth type residual film recovery machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A telescopic tooth type residual film recycling machine comprises a frame, a three-point suspension device is installed on the top of the frame, a depth-limiting wheel is installed on the bottom of the frame, a film-lifting shovel is installed at the front end of the frame, a film-collecting box is installed at the rear end of the frame, a plurality of film-winding rollers are installed on the film-collecting box along the circumferential direction, and a film-collecting port is provided on the top of the film-collecting box, lifting chains are installed on both sides of the frame, a lifting cross bar is installed between the two lifting chains, the large end side of the lifting chain is close to the film-lifting shovel, the small end side of the lifting chain is close to the film-winding roller, a driving shaft is installed on the lifting chain close to the film-winding roller, a driving wheel matched with the lifting cross bar is installed on the driving shaft, and a guide wheel is installed on the lifting chain close to the film-lifting shovel The guide wheel group includes a large guide wheel and a small guide wheel which are symmetrically arranged along the center line of the lifting chain. The large guide wheel is located at the upper and lower sides of the large end of the lifting chain, and the small guide wheel is close to the arc side of the large end of the lifting chain. An eccentric spring tooth shaft arranged parallel to the lifting cross bar is movably installed on the frame near the film lifting shovel. The eccentric spring tooth shaft is located below the symmetry line of the large guide wheel and the small guide wheel, and the eccentric spring tooth shaft is located on the inner side of the lifting cross bar. Spring teeth are arranged on both sides of the eccentric spring tooth shaft. The spring teeth are located in the gap of the lifting cross bar and extend or retract with the rotation of the lifting cross bar. The end of the spring tooth is provided with an arc film picking end which is smoothly inclined toward the outer side of the eccentric spring tooth shaft.

[0007] Furthermore, a limiting end perpendicular to the spring tooth is provided at one end of the spring tooth close to the eccentric spring tooth shaft, and the limiting end is tightly connected to the eccentric spring tooth shaft.

[0008] Furthermore, a spring tooth pressure plate is installed at each spring tooth near the eccentric spring tooth shaft, and the spring tooth pressure plate is fixed to the eccentric spring tooth shaft.

[0009] Furthermore, both sides of the film collecting box are rotatably connected to the film collecting box pull rods arranged on both sides of the frame, and a hydraulic cylinder is hingedly installed between one side of the film collecting box and the side of the frame.

[0010] Furthermore, a power input shaft is installed on the frame near the three-point suspension device, the driving wheel is installed on the driving shaft, and a first transmission wheel and a second transmission wheel are arranged side by side at one end of the driving shaft. A chain transmission is used between the power input shaft and the first transmission wheel, and a chain transmission is used between the second transmission wheel and the double-tooth film rolling roller transmission wheel arranged on one side of the film collecting box.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, the lifting chain, the lifting cross bar and the spring teeth cooperate with each other to realize the film picking, film unloading and film transportation. When picking the film, when the spring teeth rotate downward, the spring teeth extend from the lifting cross bar to pick up the mold lifted by the film lifting shovel. When the spring teeth encounter obstacles, the negative effects can be offset by their own elastic deformation. When unloading the film, when the spring teeth rotate upward, the lifting cross bar and the spring teeth begin to separate, the spring teeth begin to retract, and the film on the spring teeth falls onto the lifting cross bar to complete the film unloading. Better cooperation with the lifting chain makes the residual film recovery more thorough and clean. When transporting the film, the lifting chain and the lifting cross bar continue to rotate to transport the residual film to the film collection box for film collection, with high recovery efficiency and low impurity rate.

[0013] The utility model discloses the film recycling device is simple in structure and practical in function; through the film lifting shovel and the cooperation of the spring teeth, the lifting chain and the lifting cross bar, the residual film sheets of the farmland enter the film collecting box, so as to avoid the tearing influence of the roots on the residual film recycling; the recycling is convenient and thorough; the residual film can be further separated from the film soil, and the film can be rolled and bundled, which is convenient for the recycling and transportation of the residual film.

[0014] The residual film recycling machine solves the problem of the impact of film integrity when removing film from corn-planting fields, and realizes the simultaneous removal of film and residual film recycling. The film collecting box can be self-unloaded under the push of the hydraulic cylinder, which reduces the labor intensity of farmers and improves the efficiency of residual film recycling and corn planting benefits.

[0028] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0029] like Figure 1-11 As shown, a telescopic tooth type residual film recovery machine includes a frame 4, a three-point suspension device 14 is installed on the top of the frame 4, a power input shaft 16 is installed on the frame 4 at the three-point suspension device 14, and the power input shaft 16 is driven by a motor and a reduction box installed on the frame 4. A depth limiting wheel 6 is installed at the bottom of the frame 4, a film shovel 1 is installed at the front end of the frame 4 (the middle part of the film shovel 1 is rotatably installed on the film shovel shaft 3, and the rear end of the film shovel 1 and the bottom of the frame 4 are equipped with springs, which is a prior art), and a film collecting box 9 is installed at the rear end of the frame 4. A plurality of film rolling rollers 8 are installed on the film collecting box 9 along the circumferential direction, and a film collecting port 10 is provided at the top of the film collecting box 9. Both sides of the film collecting box 9 are rotatably connected to the film collecting box pull rods 11 arranged on both sides of the frame 4, and an oil cylinder 26 is hingedly installed between one side of the film collecting box 9 and the side of the frame 4.

[0030] Lifting chains 15 are installed on both sides of the frame 4, and a lifting cross bar 20 is installed between the two lifting chains 15. One side of the lifting chain 15 is close to the film shovel 1, and the other side of the lifting chain 15 is close to the film rolling roller 8. A driving shaft 5 is installed on the lifting chain 15 close to the film rolling roller 8, and a driving wheel 21 compatible with the lifting cross bar 20 is installed on the driving shaft 5. A guide wheel group is installed on the lifting chain 15 close to the film shovel 1 side, and the guide wheel group includes a large guide wheel 24 and a small guide wheel 23 which are symmetrically arranged along the center line of the lifting chain 15. The large guide wheel 24 is located on the upper and lower sides of the large end of the lifting chain 15, and the small guide wheel 23 is close to the arc side of the large end of the lifting chain 15. Both ends of the driving shaft 5 are rotatably mounted on the frame 4, and a first transmission wheel 22 and a second transmission wheel 25 are arranged side by side at one end of the driving shaft 5. A chain transmission is used between the power input shaft 16 and the first transmission wheel 22, and a chain transmission is used between the second transmission wheel 25 and one circle of teeth of a double-tooth film rolling roller transmission wheel 17 arranged on one side of the film collecting box 9. The other circle of teeth of the double-tooth film rolling roller transmission wheel 17 and a plurality of film rolling wheels 7 circumferentially of the film rolling roller 8 are driven by a chain.

[0031] An eccentric spring gear shaft 19 arranged parallel to the lifting cross bar 20 is movably mounted on the frame 4 near the film lifting shovel 1. The eccentric spring gear shaft 19 is located below the symmetry line of the large guide wheel 24 and the small guide wheel 23, and the eccentric spring gear shaft 19 is located inside the lifting cross bar 20. Spring teeth 2 are arranged on both sides of the eccentric spring gear shaft 19. The spring teeth 2 are located in the gap of the lifting cross bar 20 and extend or retract with the rotation of the lifting cross bar 20. The end of the spring tooth 2 is provided with an arc film picking end 12 smoothly inclined toward the outside of the eccentric spring gear shaft 19. The end of the spring tooth 2 near the eccentric spring gear shaft 19 is provided with a limit end 13 perpendicular to the spring tooth 2, and the limit end 13 is tightly connected to the eccentric spring gear shaft 19. Spring tooth pressing plates 18 are installed near the eccentric spring gear shaft 19 of the spring teeth 2, and the spring tooth pressing plates 18 are fixed to the eccentric spring gear shaft 19.

[0032] During operation, the residual film recycling machine is connected to the rear of the tractor through a three-point suspension device 14, and the power input shaft 16 is connected to the rear power output shaft of the tractor through a cross universal joint to provide power to the residual film recycling machine.

[0033] During operation, the residual film recovery machine is pulled by a tractor, and the shovel teeth of the film removing shovel 1 are wedged under the ground film to separate the ground film from the soil. The lifted ground film rises along the shovel surface of the film removing shovel 1 to the front end of the lifting chain 15 and the lifting cross bar 20, and the initial separation process of the residual film and the soil adhered to the film is realized under the overall shaking action of the lifting chain 15 and the lifting cross bar 20.

[0034] During this process, the spring tooth 2 cooperates with the lifting chain 15 and the lifting cross bar 20 to realize film picking, film unloading and film transportation. When picking up the film, during the downward movement of the spring tooth 2, the spring tooth 2 extends to pick up the mold lifted by the film lifting shovel 1. When the spring tooth 2 encounters an obstruction, it offsets the negative impact through its own elastic deformation. When unloading the film, during the upward movement of the spring tooth 2, the lifting chain 15 and the spring tooth 2 begin to separate, the spring tooth 2 begins to retract, and the film on the spring tooth 2 falls into the lifting chain 15 and the lifting cross bar 20, completing the film unloading, and the lifting chain 15 and the lifting cross bar 20 continue to rotate to transport the residual film to the film collecting box 9.

[0035] The ground film that falls into the film collecting box 9 eventually forms a residual film bundle under the rotation of the film winding roller 8. (The principle of the film winding roller is the same as that in CN202321418402.4 and CN202110224665.0, which is the prior art and not the innovation of the present utility model.) When the amount of ground film entering the film collecting box 9 increases, the diameter of the film bundle gradually increases, and the film bundle gradually fills the entire film collecting box 9, the hydraulic cylinder 26 switch is turned on, and under the action of the hydraulic cylinder 26, the film collecting box 9 begins to rotate backward by a certain angle. As the angle between the outlet of the film collecting box 9 and the horizontal plane decreases, the film bundle is automatically discharged from the film winding and collecting device and falls to the ground to complete the self-unloading process of recovering the film bundle.
