Description

Technical Field

[0001] This utility model belongs to the technical field of feeding devices, and specifically relates to a foldable, non-dropping multi-functional two-stage feeding device. Background Technology

[0002] Forage shredders are used to crush plant materials such as hay and straw into fine particles similar to rice bran and wheat bran, making them easier for animals to digest and absorb, thus improving feed utilization and palatability. The applicant's initial research and development focused on improving the crushing quality and efficiency of forage shredders, and several patents were applied for. Market research revealed that farmers use forage shredders not only for hay but also for crushing various plant materials such as corn and potatoes. Some materials are long, some short, some require rapid feeding, and some require gentle feeding. Existing forage shredders typically have fixed feeding devices, which are not conducive to feeding operations. Some have suggested making the hopper of the forage shredder adjustable, which, while meeting more feeding needs, still has some shortcomings. For example, when crushing long stalks such as corn stalks, a longer hopper is required. If the hopper is tilted, the stalks must be raised during feeding, which is inconvenient and laborious. If the hopper is set too gently, it is not conducive to subsequent crushing (reducing crushing efficiency).

[0003] To better meet user needs, facilitate user operation, and improve user experience, the applicant further improved the feeding device of the hay shredder by changing it into a two-stage feeding device, and enabling seamless connection and adjustment between the two stages. Utility Model Content

[0004] The purpose of this invention is to provide a foldable, non-dropping, multi-functional two-stage feeding device, thereby overcoming the problem that the feeding device of the existing hay shredder is not conducive to feeding different materials.

[0005] The specific technical solution is as follows:

[0006] A foldable, non-dropping, multi-functional two-stage feeding device includes a primary feeding hopper and a secondary feeding hopper. The secondary feeding hopper is connected to a frame. The lower part of the primary feeding hopper is oscillatingly connected to the secondary feeding hopper via a first rotating shaft. The upper part of the secondary feeding hopper is adjustablely fixed to the frame via a connector. A first hollow sleeve is fixed to the end of the primary feeding hopper. Perforated fixing parts are respectively provided on the lower sides of the end of the secondary feeding hopper. The fixing parts are located on the outside of the primary feeding hopper. The first rotating shaft passes through the perforation of the fixing part and the first hollow sleeve, realizing the oscillating connection between the lower part of the primary feeding hopper and the secondary feeding hopper.

[0007] By setting up two-stage feeding hoppers, and welding a hollow sleeve to the end of the first-stage feeding hopper, and setting a fixed part with a perforation below the end of the second-stage feeding hopper, and then connecting them by a rotating shaft passing through the perforation and the hollow sleeve, the angle of the first-stage feeding hopper can be adjusted arbitrarily during use, and the hollow sleeve is always in close contact with the bottom plate of the second-stage feeding hopper. Whether crushing straw crops or granular crops such as corn, there will be no material falling off.

[0008] Preferably, the upper part of the primary feed hopper is fixed to the frame by a shrinking screw, resulting in a stable structure.

[0009] Preferably, the retractable screw includes a hopper fixing part, a frame fixing part, a connecting part, a screw, and a bolt. The hopper fixing part is located on the upper part of the primary feed hopper, and the frame fixing part is located on the upper part of the frame. The hopper fixing part has a hinge hole and a screw through hole. One end of the connecting part is hinged to the hopper fixing part, and the other end is fixed with the screw. The other end of the screw passes through the screw through hole of the frame fixing part and is fixed to the frame fixing part by bolts. The tilt angle of the primary feed hopper can be adjusted by extending and retracting the screw and adjusting the fixed position of the screw and the frame fixing part.

[0010] Preferably, the secondary feed hopper is welded and fixed to the frame.

[0011] Preferably, a second hollow sleeve is fixed to the end of the secondary feed hopper, and perforated mounting parts are respectively provided on both sides of the frame. The mounting parts are located on the lower outer side of the secondary feed hopper, and the second rotating shaft passes through the perforation of the mounting part and the second hollow sleeve to realize the swing connection between the lower part of the secondary feed hopper and the frame. The upper part of the secondary feed hopper is adjustablely fixed to the frame by a binding rope, a shrink screw or an adjustable bracket.

[0012] Preferably, the upper part of the primary feed hopper is connected to the frame via a telescopic sleeve.

[0013] Preferably, both the primary feed hopper and the secondary feed hopper include a bottom plate and a side plate. At the connection between the primary feed hopper and the secondary feed hopper, the height of the bottom plate of the primary feed hopper is higher than the height of the bottom plate of the secondary feed hopper, and the side plate of the primary feed hopper is located inside the side plate of the secondary feed hopper.

[0014] Preferably, the opening size of the primary feed hopper and / or the secondary feed hopper at one end near the frame is smaller than the opening size at the other end.

[0015] Preferably, the length of the primary feed hopper is longer than the length of the secondary feed hopper, which is beneficial for feeding.

[0016] Preferably, the secondary feed hopper is also equipped with a feed funnel for adding other materials.

[0017] Compared with existing technologies, this utility model has the following beneficial effects:

[0018] 1. This utility model features a two-stage feeding hopper. A hollow sleeve is welded to the end of the first-stage feeding hopper, and a fixed part with a perforation is provided below the end of the second-stage feeding hopper. The two hoppers are connected by a rotating shaft that passes through the perforation and the hollow sleeve. In this case, the bottom plate of the second-stage feeding hopper is close to the hollow sleeve. During the adjustment of the tilt angle of the first-stage feeding hopper, the hollow sleeve rotates around the rotating shaft. The hollow sleeve is always close to the bottom plate of the second-stage feeding hopper. Whether crushing straw crops or granular crops such as corn, there will be no material spillage.

[0019] 2. The secondary feed hopper of this utility model can be fixed to the frame or hinged to the frame. When the secondary feed hopper is hinged to the frame and connected to the frame through a hollow sleeve, the angle can be adjusted arbitrarily without material falling out. Furthermore, the angles of the primary and secondary feed hoppers can be set differently to meet the feeding needs of different crops. For example, when crushing corn stalks, installing this multi-functional secondary feed device on a hay crusher allows the primary feed hopper to be adjusted to be horizontal or slightly tilted for easy manual feeding, while a larger tilt angle of the secondary feed hopper is beneficial for stalk crushing. In other words, the dual-adjustable feed hopper design can meet the feeding needs of more crops.

[0020] 3. This foldable, non-dropping, multi-functional two-stage feeding device can be used with a hay shredder to meet the feeding needs of different crops such as corn, potatoes, hay, and straw, thus better meeting the needs of different customers. Attached Figure Description

[0033] Example 1

[0034] like Figure 1 As shown, a foldable, non-dropping multi-functional two-stage feeding device includes a primary feeding hopper 1 and a secondary feeding hopper 2. The lower front end of the primary feeding hopper 1 is hinged to the secondary feeding hopper 2 via a first rotating shaft 3, and the upper part is adjustablely fixed to the frame 7 via a shrink screw 4. The secondary feeding hopper 2 is fixed to the frame 7.

[0035] This application improves the connection structure between the first-stage feed hopper 1 and the second-stage feed hopper 2 by setting up a two-stage feed hopper, so that the first-stage feed hopper 1 will not drop material even when its angle is adjusted arbitrarily. This can meet the feeding needs of different crops and solve the problem that the feeding device of the existing forage crusher is not conducive to the feeding operation of different materials.

[0036] like Figure 2 As shown, a first hollow sleeve 5 is welded to the end of the primary feed hopper 1, and the first hollow sleeve 5 is welded below the bottom plate 11 of the primary feed hopper 1. A fixing part 6 with perforations is respectively provided on both sides of the lower end of the secondary feed hopper 2, and the fixing part 6 is located on the outer sides of the primary feed hopper 1. One end of the first rotating shaft 3 is provided with a protruding gripping part, and the other end is provided with a limiting hole. After the first rotating shaft 3 passes through the perforation, the first hollow sleeve 5, and the other perforation, a wire can be inserted into the limiting hole to achieve a swing connection between the lower part of the primary feed hopper 1 and the secondary feed hopper 2. The wire can also be replaced with a bolt 45 or other objects. This application, by setting a hollow sleeve at the front end of the primary feed hopper 1 and hinged to the secondary feed hopper 2, allows for arbitrary adjustment of the tilt angle of the primary feed hopper 1. The hollow sleeve is always in close contact with the bottom plate 11 of the secondary feed hopper 2, preventing material spillage and meeting the feeding needs of small-particle crops such as corn.

[0037] Combination Figure 4-5The shrinking screw 4 includes a hopper fixing part 41, a frame fixing part 42, a connecting part 43, a screw 44, and bolts 45. The hopper fixing part 41 is located on the upper part of the primary feed hopper 1, and the frame fixing part 42 is located on the upper part of the frame 7. The hopper fixing part 41 has a hinge hole, and the frame fixing part 42 has a through hole for the screw 44. One end of the connecting part 43 is hinged to the hopper fixing part 41, and the other end is fixed to the screw 44. The other end of the screw 44 passes through the through hole of the frame fixing part 42. The screw 44 is fixed to the frame fixing part 42 by bolts 45 respectively set on the beam side of the through hole of the screw 44. In this embodiment, the through hole of the screw 44 is set to be slightly larger than the screw 44, and the inner wall of the through hole of the screw 44 is smooth, which is conducive to the movement and adjustment of the screw 44. When a larger tilt angle of the primary feed hopper 1 needs to be adjusted, the screw 44 can be pulled to shorten the distance between the hopper fixing part 41 and the frame fixing part 42, and the bolts 45 on both sides of the through hole of the screw 44 can be tightened to achieve the angle adjustment and fixation of the primary feed hopper 1. When a smaller tilt angle of the primary feed hopper 1 needs to be adjusted, the screw 44 can be loosened to a suitable position and then fixed. The design of the retractable screw 4 makes the overall structure more stable and occupies less space.

[0038] In this embodiment, the secondary feed hopper 2 is fixed to the frame 7 by welding.

[0039] In other embodiments, the secondary feed hopper 2 can also be provided with a second hollow sleeve at the lower end of one end of the primary feed hopper 1. Then, referring to the connection structure of the lower parts of the primary feed hopper 1 and the secondary feed hopper 2, the secondary feed hopper 2 is hinged to the frame 7. Specifically, the frame 7 is provided with perforated mounting parts on both sides. The mounting parts are located on the lower outer side of the secondary feed hopper 2. The second rotating shaft passes through the perforation of the mounting part and the second hollow sleeve, realizing the swing connection between the lower part of the secondary feed hopper 2 and the frame 7. The upper part of the secondary feed hopper 2 is adjustablely fixed to the frame 7 by a binding rope, a shrink screw 4, or an adjustable bracket.

[0040] Combination Figure 1 Both the primary feed hopper 1 and the secondary feed hopper 2 include a bottom plate 11, a side plate 12, and a top plate 13. The opening size of the primary feed hopper 1 and / or the secondary feed hopper 2 near the frame 7 is smaller than the opening size at the other end, which is beneficial for feeding. Furthermore, the length of the top plate 13 of the primary feed hopper 1 is less than the length of the bottom plate 11 of the primary feed hopper 1. The upper part of the primary feed hopper 1 away from the secondary feed hopper 2 is hollowed out, while the end closer to the secondary feed hopper 2 is a square cylindrical shape, and the secondary feed hopper 2 is also a square cylindrical shape, which facilitates processing and feeding. Of course, in other embodiments, the side plates 12 and the top plate 13 of the primary feed hopper 1 and the secondary feed hopper 2 can also be formed into an arc shape.

[0041] Combination Figure 4The multi-functional two-stage feeding device of this application is installed on a hay shredder, and the hay shredder is used to shred corn stalks. At this time, the primary feed hopper needs to be adjusted to a horizontal or slightly inclined position. Because corn stalks are relatively long, if the primary feed hopper 1 is too inclined, it is not conducive to manual feeding. At the same time, to facilitate the shredding of corn stalks by the shredder, the inclination angle of the secondary feed hopper 2 should be larger, such as adjusting the inclination angle to 20 degrees. Combined with... Figure 5 If potatoes need to be crushed, the tilt angle of the primary feed hopper 1 should be increased, and the tilt angle of the secondary feed hopper 2 should be decreased. A larger tilt angle for the primary feed hopper 1 compared to the secondary feed hopper 2 facilitates potato feeding and creates a certain compressive force on the potatoes in the secondary feed hopper 2, which is beneficial for crushing. This application allows adjustment of the angles of the primary feed hopper 1 and the secondary feed hopper 2 according to the crushing and feeding requirements of different crops. It can be used for crushing and feeding straw-like crops as well as granular crops, meeting the needs of different applications.

[0042] In summary, this utility model features a two-stage feeding hopper. A hollow sleeve is welded to the end of the first-stage feeding hopper 1, and a perforated fixing part 6 is provided below the end of the second-stage feeding hopper 2. The hoppers are connected by a rotating shaft passing through the perforation and the hollow sleeve. During use, the angle of the first-stage feeding hopper 1 can be adjusted arbitrarily, while the hollow sleeve remains in close contact with the bottom plate 11 of the second-stage feeding hopper 2. This prevents material spillage, whether crushing straw or granular crops such as corn. The first-stage and second-stage feeding hoppers 1 and 2 can also be adjusted to different angles to meet the feeding needs of different crops. This utility model can be used in conjunction with a forage crusher to meet the feeding needs of various crops such as corn, potatoes, forage, and straw.
