Description

Technical Field

[0001] The utility model relates to a bag filling device, in particular to a seedling substrate bag filling device. Background Technique

[0002] A seedling substrate is a mixture used for seedling raising, which is composed of suitable alkaline and neutral fertile soils, coal ash, concrete gravel, pine needles and other solid substances, organic substances, fertilizers, etc. Through careful sorting, the substrate makes it easier for plants to absorb the required water and nutrients to maintain the healthy growth of plants. The seedling substrate can be mixed by different constituent components, which can improve the stability and resistance of the seedling raising environment, enhance the protection of plant roots, promote the rapid growth and development and stress resistance of plants, and is beneficial to the success of seedling raising.

[0003] The seedling substrate is usually filled into woven bags or plastic bags for packaging. The commonly used bag filling method at present is to place the packaging bag on a weighing scale, and then directly inject the substrate into the packaging bag by using a screw feeder or other feeding equipment. When the required weight of the seedling substrate is filled into the packaging bag, the filling is stopped. Although this method is simple, in the actual use process, due to problems such as the display delay of the weighing scale and the shutdown delay of the feeding machine, it is not convenient to accurately control the bag filling amount. For this reason, we propose a seedling substrate bag filling device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a seedling substrate bag filling device to solve the problems put forward in the above background technique.

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0018] Please refer to Figures 1 to 3 , in the embodiment of the present invention, a seedling substrate bagging device includes a spiral feeder 1 and an equal - amount cloth - feeding mechanism. The equal - amount cloth - feeding mechanism includes a pallet 3 fixed to the top of the bracket 4. A discharge hopper 5 penetrates through the bottom of the pallet 3. A cam divider 6 driven by a reduction motor 7 is fixedly installed at the bottom of the pallet 3. The output shaft of the cam divider 6 is fixedly connected to a rotating shaft 8. The top end of the rotating shaft 8 is fixedly connected to a cylinder 9. A plurality of storage bins 14 with variable volumes are arranged on the cylinder 9. A scraper 20 is arranged inside the cylinder 9. The discharge port of the spiral feeder 1 is located directly above the opening of the cylinder 9 and corresponds to the scraper 20. The feed port of the spiral feeder 1 is communicated with a hopper 2.

[0019] By adopting the above - mentioned solution, when in use, after pouring the prepared and mixed seedling substrate into the hopper 2, starting the spiral feeder 1 can convey the seedling substrate to the inside of the scraper 20 in the cylinder 9, and then it falls into the storage bin 14. By starting the reduction motor 7 to drive the cam divider 6 to operate, the cylinder 9 can make intermittent circular rotation, so that each storage bin 14 rotates in a cycle under the discharge port of the spiral feeder 1 and the scraper 20. When a storage bin 14 is filled with the seedling substrate, the cylinder 9 rotates by a certain angle, and this storage bin 14 can be moved away from under the scraper 20, and an empty storage bin 14 can be moved under the scraper 20 and aligned with the discharge port of the spiral feeder 1. During this process, the seedling substrate protruding from the top opening of the storage bin 14 will be scraped off by the scraper 20 and enter the empty storage bin 14. When the storage bin 14 filled with the seedling substrate is moved to be aligned with the discharge hopper 5, the seedling substrate inside it will be discharged from the discharge hopper 5. Therefore, just by sleeving the packaging table at the bottom end of the discharge hopper 5, the required amount of seedling substrate can be filled into the packaging bag. The operation is simple and convenient, and it is easy to control the bagging amount.

[0020] Specific combination Figures 1 - 3 In an embodiment of the present utility model, the storage bin 14 includes an inner tube 12 and a sleeve 10. The sleeve 10 is slidably sleeved at the bottom end of the inner tube 12. The bottom end of the sleeve 10 penetrates through the bottom of the cylinder 9 and is fixedly connected with a polytetrafluoroethylene ring 21. The bottom of the polytetrafluoroethylene ring 21 is attached to the top surface of the support plate 3. The opening size of the bottom end of the sleeve 10 is adapted to the feeding port size of the discharge hopper 5. A flat plate 11 is connected to the support plate 3 through a lifting mechanism. The flat plate 11 is slidably installed in the cylinder 9. The top ends of the inner tubes 12 all penetrate through the flat plate 11, and the top ends of the inner tubes 12 are flush with the top surface of the flat plate 11. A plurality of the sleeves 10 are circumferentially distributed in the cylinder 9, and the discharge hopper 5 is located on the moving path of the sleeve 10.

[0021] The lifting mechanism drives the flat plate 11 to slide in the cylinder 9, so as to control the length of the inner tube 12 extending out of the sleeve 10, thereby changing the volume of the storage bin 14. The operation is simple and convenient.

[0022] Specific combination Figures 1 - 3 In an embodiment of the present utility model, the lifting mechanism includes a gantry 15 fixedly installed on the top of the support plate 3. The cylinder 9 is located inside the gantry 15. The top of the gantry 15 is fixedly connected with an electric cylinder 16. The push rod end of the electric cylinder 16 is fixedly connected with a connecting plate 17. The bottom of the connecting plate 17 is fixedly connected with a connecting shaft 18. The bottom end of the connecting shaft 18 is rotationally connected with the flat plate 11 through a bearing seat. The scraping plate 20 is fixedly connected with the connecting plate 17, and the bottom of the scraping plate 20 is attached to the top of the flat plate 11.

[0023] By starting the electric cylinder 16, the connecting plate 17 can be driven to lift and lower, so as to adjust the height of the flat plate 11 in the cylinder 9, thereby changing the volume of the storage bin 14. Through the setting of the connecting shaft 18 and the bearing seat, when the cylinder 9 rotates driven by the cam divider 6, the flat plate 11 can be driven to rotate relative to the connecting shaft 18, so as to avoid interference of the lifting mechanism, the flat plate 11, etc. on the rotation of the cylinder 9 and the flat plate 11. By fixing the scraping plate 20 to the flat plate 11, the scraping plate 20 can be prevented from rotating together with the cylinder 9, so as to ensure that the scraping plate 20 scrapes off the seedling substrate protruding from the top end of the inner tube 12.

[0024] Specific combination Figure 2 In an embodiment of the present utility model, a plurality of springs 13 are arranged in the cylinder 9. The top ends of the springs 13 abut against the bottom of the flat plate 11 to utilize the elastic force of the springs 13 to play an auxiliary supporting role for the flat plate 11 in the cylinder 9.

[0025] Specific combination Figure 2, in an embodiment of the present utility model, a plurality of guide rods 19 are slidably penetrated through the top of the gantry 15, and the bottom ends of the guide rods 19 are fixedly connected to the connecting plate 17, so as to utilize the sliding fit between the guide rods 19 and the gantry 15 to guide the connecting plate 17, thereby improving the stability of the connecting plate 17 during the lifting process.

[0026] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
