Description

Technical Field

[0001] The invention belongs to agricultural machinery, and mainly relates to an automatic grain box bag filling device used in conjunction with a grain combine harvester in a plot. Background Art

[0002] Since the crop planting area in the community is small and the grain harvest volume is not large, the grain tank size of the grain combine harvester used for the grain harvesting operation in the community is small, so the grain storage volume is small each time. The traditional bulk centralized loading method is not suitable for the grain combine harvester operation in the community. Not only does it have many grain unloading times, it is especially not suitable for use with loading vehicles, and the efficiency of machine use is low. At the same time, the purpose of planting in the community is mostly to breed new varieties of crops and cultivate improved varieties. The grains need to be strictly separated, cleaned, stored and kept. The bulk unloading method is not conducive to the protection of new and improved varieties. Summary of the invention

[0003] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, combine with the actual needs of new variety breeding and improved seed cultivation and harvesting operations in the community, and study and design an automatic bag filling device for the grain box of a community grain combine harvester, so as to adapt to and meet the needs of community grain harvesting operations, improve the efficiency of machine operation, reduce operating costs, ensure the quality of community crop harvesting and storage, and provide technical support for community planting models.

[0004] The purpose of the invention is achieved in this way: a driving shaft is installed on the fixed groove plate in an axially and radially positioned and circumferentially rotatable manner, a fixed motor is connected to the bottom end of the driving shaft through a shaft sleeve, a ratchet and a telescopic driving plate are sequentially mounted on the driving shaft located on the upper part of the fixed groove plate from top to bottom, an involute hole groove is provided on the telescopic driving plate, a grain bag support plate is telescopically movably installed on the fixed groove plate, a column pin is fixed on the upper inner part of the grain bag support plate, the column pin is movably inserted into the involute hole groove to connect the telescopic driving plate with the grain bag support plate, and the grain bag driving plates are respectively relatively mounted on the upper outer side of the grain bag support plate; a support plate arc track is fixed on the lower end surface of the ratchet, a bag filling control plate is rotatably supported and installed on the support plate arc track, A pawl is swingably hingedly installed on the side wall surface of the inner hole of the bag filling control plate, and the pawl and the ratchet are in circumferential locking cooperation and circumferential sliding cooperation. The two ends of the tension spring are respectively connected to the bag filling control plate and the pawl, so that the pawl and the ratchet are in reliable and tight contact cooperation; a double-track slide is fixedly arranged at the lower part of the arc track of the support plate, and the hanging ring is movably mounted on the double-track slide. The grain bag is placed on the part of the grain bag support plate between the relatively equipped grain bag driving plates. The upper end of the grain bag is connected to the hanging ring through a connecting clip, and the upper end of the grain bag is located below the grain outlet of the grain delivery pipe; an arc-shaped grain delivery hole is opened on the bag filling control plate, and the arc-shaped grain delivery hole connects the grain delivery pipe with the grain bag, thereby constituting an automatic bag filling device for the grain box of the community grain combine harvester.

[0005] The invention realizes the automatic bag filling operation when the grain box of the grain combine harvester in the plot is unloaded, avoids and eliminates the mixing of new varieties of crops or high-quality varieties bred in the plot, reduces the subsequent packaging operation procedures, facilitates transportation and safekeeping and storage, and has the characteristics of unique and reasonable structure, high operating efficiency, simple and convenient operation, and reliable use.

DETAILED DESCRIPTION

[0012] The following is a detailed description of the implementation scheme of the invention in conjunction with the accompanying drawings. An automatic bag filling device for a grain box of a community grain combine harvester includes a grain box 1 and a grain delivery pipe 2 mounted on the lower side of the grain box 1, a drive shaft 15 is installed on the fixed slot plate 11 in an axially and radially positioned and circumferentially rotatable manner, a fixed motor 9 is connected to the bottom end of the drive shaft 15 through a sleeve 10, a ratchet 4 and a telescopic drive plate 12 are sequentially mounted on the drive shaft 15 located on the upper side of the fixed slot plate 11 from top to bottom, an involute hole 14 is provided on the telescopic drive plate 12, a grain bag support plate 8 is telescopically and movably installed on the fixed slot plate 11, a pin 18 is fixed on the upper inner side of the grain bag support plate 8, the pin 18 is movably inserted into the involute hole 14 to connect the telescopic drive plate 12 with the grain bag support plate 8, and grain bag drive plates 7 are respectively mounted on the upper outer side of the grain bag support plate 8; a support plate arc track 20 is fixed on the lower end surface of the ratchet 4, and the grain bag is filled with a bag. The bag control plate 17 is rotatably supported and installed on the support plate arc track 20, and the pawl 3 is swingably hingedly installed on the side wall surface of the inner hole of the bag filling control plate 17. The pawl 3 and the ratchet 4 are in circumferential locking cooperation and circumferential sliding cooperation. The two ends of the tension spring 5 are respectively connected to the bag filling control plate 17 and the pawl 3, so that the pawl 3 and the ratchet 4 are in reliable and tight contact cooperation; a double-track slide 6 is fixedly arranged at the lower part of the support plate arc track 20, and the hanging ring 16 is movably mounted on the double-track slide 6. The grain bag 19 is placed on the grain bag support plate 8 between the relatively equipped grain bag driving plates 7. The upper end of the grain bag 19 is connected to the hanging ring 16 through the connecting clip 13, and the upper end of the grain bag 19 is located below the grain outlet of the grain delivery pipe 2; an arc-shaped grain delivery hole 21 is opened on the bag filling control plate 17, and the arc-shaped grain delivery hole 21 connects the grain delivery pipe 2 with the grain bag 19.

[0013] During bag filling operation, the rotating motor 9 drives the telescopic driving plate 12 and the ratchet 4 to rotate synchronously through the shaft sleeve 10 and the driving shaft 15. The involute hole groove 14 on the telescopic driving plate 12 drives the grain bag support plate 8 to retract through the pin 18. The grain bag 19, the connecting clip 13, and the hanging ring 16 are driven to retract synchronously on the double-track slide 6 through the grain bag driving plate 7, so that the upper end of the grain bag 19 is located below the grain outlet of the grain conveying pipe 2. At the same time, the rotating ratchet 4 drives the bag filling control plate 17 to rotate under the support of the arc track 20 of the support plate through the ratchet 3. When the arc grain conveying hole on the bag filling control plate 17 is When the motor 21 rotates to the position between the upper end of the grain bag 19 and the grain outlet of the grain delivery pipe 2, the grain in the grain box 1 begins to be filled into the grain bag 19. When the arc-shaped grain delivery hole 21 on the bag filling control plate 17 continues to rotate and leaves the position between the upper end of the grain bag 19 and the grain outlet of the grain delivery pipe 2, the bag filling operation is stopped and completed; the motor 9 reverses, and under the action of the telescopic driving plate 12 and the grain bag driving plate 7, the grain bag 19 filled with grain moves outward, and the bag unloading operation is completed manually; synchronously, the ratchet 4 reverses, the bag filling control plate 17 is stationary, and the grain outlet of the grain delivery pipe 2 is closed under the blocking of the bag filling control plate 17. After the empty grain bag 19 is clamped, the above-mentioned starting action is repeated, and the bag filling operation is completed in sequence.
