Description

Technical Field

[0001] The utility model relates to the field of seed packaging equipment, and more specifically, to a feeding device for a seed sub-packaging scale. Background Art

[0002] A seed sub-packaging scale, also known as a seed packaging scale, is used for weighing and packing particulate matters such as seeds. During operation, it generally uses a bucket elevator to transport seeds to the feed hopper of the seed sub-packaging scale. After being weighed in the weighing bin, the seeds are poured into a packaging bag. When feeding traditional seed sub-packaging scales, due to the limited volume of the feeding hopper of the bucket elevator, it is necessary for workers to track the feeding situation manually and continuously pour seeds into the feeding hopper. This feeding method is rather cumbersome, with high labor intensity for workers and high labor costs.

[0003] To solve the above problems, people have been seeking an ideal technical solution. Summary of the Invention

[0004] The purpose of the utility model is to address the deficiencies of the prior art, and thus provide a feeding device for a seed sub-packaging scale with scientific design, no need for frequent manual feeding replenishment, low labor intensity for workers, and strong practicability.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a feeding device for a seed sub-packaging scale, including a bucket elevator, a storage bin, and a conveyor belt. The bottom end of the bucket elevator is provided with a feed hopper. The bottom of the storage bin is provided with a discharge square pipe. The bottom end of the discharge square pipe is open and is attached to the belt surface of the conveyor belt. The discharge square pipe is provided with a discharge notch on the side wall facing the conveying direction of the conveyor belt, so that the conveyor belt can carry the material out from the discharge notch. The output end of the conveyor belt extends above the feed hopper.

[0006] Based on the above, a lifting gate is further installed on the side wall of the discharge square pipe above the discharge notch. Two vertical long travel holes are opened on the lifting gate. Locking bolts are respectively provided on the discharge square pipe corresponding to the two vertical long travel holes. The opening degree of the discharge notch is adjusted by lifting the lifting gate.

[0007] Based on the above, soft leather retaining edges with wrinkles are respectively arranged on both sides of the conveyor belt.

[0008] Based on the above, a lining plate is fixedly installed on the frame of the conveyor belt. The lining plate abuts against the bottom of the upper belt surface of the conveyor belt and is located directly below the discharge square pipe.

[0009] Based on the above, one end of the lining plate facing the input direction of the conveyor belt is provided with a rounded corner.

[0010] The utility model has substantial features and progress compared with the prior art. Specifically, in the utility model, by arranging the discharge square pipe and opening the discharge notch, the seeds in the storage bin are directly pressed on the conveyor belt. Along with the transmission of the conveyor belt, under the action of friction, the seeds pass through the discharge notch and are carried out, and finally are conveyed to the feed hopper of the bucket elevator, realizing automatic continuous feeding. It has the advantages of scientific design, no need for frequent manual supplementary feeding, low labor intensity of workers, and strong practicability.

[0011] Furthermore, by lifting the lifting gate plate, the opening degree of the discharge notch can be adjusted, thereby adjusting the discharge speed of the seeds; the setting of the soft leather edge can prevent the seeds from falling from both sides during the transmission process.

[0012] Furthermore, the setting of the lining plate can play a role in lifting the upper belt surface of the conveyor belt, preventing the materials in the storage bin from deforming the conveyor belt and ensuring normal discharge; the setting of the rounded corners can avoid scratching between the lining plate and the belt body of the conveyor belt and extend the service life.

[0017] The following further describes the technical solutions of the utility model in detail through specific embodiments.

[0018] Such as Figures 1-3As shown in the figure, a feeding device for a seed sub-packaging scale includes a bucket elevator 1, a storage bin 2, and a conveyor belt 3. The bottom end of the bucket elevator 1 is provided with a feed hopper 4. The output end of the bucket elevator 1 extends above the feed inlet of the sub-packaging scale 5. The bottom of the storage bin 2 is provided with a discharge square pipe 6. The bottom end of the discharge square pipe 6 is open and abuts against the belt surface of the conveyor belt 3. An outlet notch 7 is formed in the side wall of the discharge square pipe 6 facing the conveying direction of the conveyor belt 3, so that the conveyor belt 3 can take out the material from the outlet notch 7. The output end of the conveyor belt 3 extends above the feed hopper 4.

[0019] During specific use, the seeds are stored in the storage bin 2. After passing through the discharge square pipe 6, the seeds are pressed on the belt surface of the conveyor belt 3. With the transmission of the conveyor belt 3, under the action of friction, the seeds pass through the outlet notch 7 and are taken out, and finally conveyed into the feed hopper 4 of the bucket elevator 1. The bucket elevator 1 then conveys the seeds into the sub-packaging scale 5, realizing continuous feeding from the storage bin 2 to the sub-packaging scale 5.

[0020] To facilitate the adjustment of the discharge speed, a lifting gate 8 is further installed on the side wall of the discharge square pipe 6 above the outlet notch 7. Two vertical long holes 9 are formed in the lifting gate 8. Corresponding to the two vertical long holes 9 on the discharge square pipe 6, locking bolts 10 are respectively provided to adjust its height and lock it. The lifting gate 8 adjusts the opening degree of the outlet notch 7 through lifting, thereby adjusting the discharge speed of the seeds.

[0021] To prevent the seeds from falling from both sides during transportation, soft leather retaining edges 11 with folds are respectively arranged on both sides of the conveyor belt 3.

[0022] To prevent the conveyor belt 3 from being deformed by the pressure of the seeds, a lining plate 32 is fixedly installed on the frame 31 of the conveyor belt 3. The lining plate 32 abuts against the bottom of the upper belt surface of the conveyor belt 3 and is located directly below the discharge square pipe 6, playing a role in supporting the upper belt surface of the conveyor belt 3 to prevent deformation and ensure normal discharge. One end of the lining plate 32 facing the input direction of the conveyor belt 3 is provided with a rounded corner 12, which can avoid scratching between the lining plate 32 and the belt body of the conveyor belt 3 and extend the service life.

[0023] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: still, the specific implementation manners of the present invention can be modified or some technical features can be equivalently replaced; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
