Abstract
Description
Technical Field
[0001] This utility model relates to the field of baling machine technology, specifically a folding screen for baling machines. Background Technology
[0002] A baler is a mechanical device used to compress and bundle materials such as crop straw, hay, and waste paper. It is widely used in agriculture, animal husbandry, and papermaking, effectively improving the efficiency of material transportation and storage. The sieve cylinder in a baler is a key component for screening and filtering materials. The sieve cylinder typically consists of a cylindrical frame, a screen, and other components.
[0003] The screen cylinder on the existing baler is in a fixed position and cannot be folded. When the baler moves, it cannot pass through sections of road with height restrictions and must be detoured, which increases transportation costs. Moreover, when the screen cylinder is not in use, its fixed position and inability to be folded will occupy a large storage space, which is not conducive to the storage and management of the equipment. At the same time, when replacing the screen or performing maintenance, the fixed position of the screen cylinder is inconvenient to operate and requires more labor and time. Utility Model Content
[0004] The purpose of this invention is to provide a folding screen for a baler to solve the problems mentioned in the background art.

A first vertical plate and a second vertical plate are fixed at the top of the base plate respectively. An inclined plate is fixed between the first vertical plate and the second vertical plate. The inclined plate is located below the screen cylinder.
[0007] A conveying mechanism is installed between the first and second vertical plates for conveying and bundling the screened material, and the conveying mechanism is located below the discharge chute.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4 As shown, a folding screen for a baler includes a base plate 1 and a screen cylinder 2 disposed above the base plate 1. The inner wall of the screen cylinder 2 is connected to a discharge trough 3. A filter screen 4 is fixed to the bottom of the screen cylinder 2. A first vertical plate 5 and a second vertical plate 6 are fixed to the top of the base plate 1 respectively. An inclined plate 7 is fixed between the first vertical plate 5 and the second vertical plate 6. The inclined plate 7 is disposed below the screen cylinder 2. The base plate 1 is installed inside the baler. The specific working principle of the baler has been disclosed in the prior art and will not be described in detail here. The screen cylinder 2 is used to screen the material to be baled for impurities. The material enters from the top inlet of the screen cylinder 2 and is screened by the screen cylinder 2. Impurities are discharged from below the filter screen 4. The material is discharged from the discharge trough 3. The screened impurities fall on the inclined plate 7 and are discharged from the inclined plate 7 for collection. After being discharged from the discharge trough 3, the material falls on the conveying mechanism 8. The first vertical plate 5 and the second vertical plate 6 can support the installation of the conveying mechanism 8, improving the stability of the conveying mechanism 8.
[0026] A conveying mechanism 8, located between the first vertical plate 5 and the second vertical plate 6, is used to transport and bundle the screened material. The conveying mechanism 8 is positioned below the discharge chute 3. It transports the material falling from the discharge chute 3 to the bundling structure within the bundling machine for bundling. The conveying mechanism 8 includes a motor 81 fixed to one side of the first vertical plate 5. A first synchronous pulley 82 is fixed to the output end of the motor 81. A synchronous conveyor belt 83 is driven to the outer side of the first synchronous pulley 82, and several second synchronous pulleys 84 are driven to the inner side of the synchronous conveyor belt 83. The first synchronous pulley 82 and the second synchronous belt... The wheels 84 are rotatably connected to the inner walls of the first vertical plate 5 and the second vertical plate 6. A motor 81 is fixedly installed on one side of the first vertical plate 5. By starting the motor 81, the first synchronous pulley 82 can be driven to rotate. When the first synchronous pulley 82 rotates, it can drive the synchronous conveyor belt 83 connected to its outer side to rotate synchronously. When the synchronous conveyor belt 83 rotates, it can transport the material falling on it. When the synchronous conveyor belt 83 rotates, several second synchronous pulleys 84 on its inner side will rotate synchronously. Through the rotational support of the second synchronous pulleys 84, the stability of the synchronous conveyor belt 83 rotation can be improved, thereby improving the stability of material conveying and bundling.
[0027] A flipping mechanism 9, located on the top of the base plate 1, is used to fold the sieve cylinder 2. This mechanism allows the sieve cylinder 2 to be flipped when not in use, preventing it from being installed too high on the baler and allowing the baler to fold over height restrictions during movement. The flipping mechanism 9 includes a cylinder 91 fixed to the top of the base plate 1, with a moving plate 92 fixed to the piston rod of the cylinder 91. A track 93 is slidably connected to the bottom of the moving plate 92. Fixed to the top of the base plate 1, the track 93 has limit blocks 94 fixed at both ends; the top of the movable plate 92 is fixed with a rack 95, and a gear 96 is meshed with the outer side of the rack 95; a rotating shaft 97 is fixed at the shaft center of the gear 96, and a bearing 98 is rotatably connected to the outer side of the rotating shaft 97, with one end of the rotating shaft 97 fixed to the outer side of the screen cylinder 2; a support frame 99 is fixed to the outer side of the bearing 98, and the support frame 99 is fixed to the top of the base plate 1. By setting a cylinder 91, the movable plate 92 can be moved by its own power. The movement of the movable plate 92 causes the rack 95 fixed on its top to move synchronously. Since the track 93 is slidably connected to the bottom of the movable plate 92 and fixed to the top of the base plate 1, the track 93 can effectively support the movement of the movable plate 92 and improve the stability of the movement of the movable plate 92. By fixing the limiting blocks 94 at both ends of the track 93, the movement of the movable plate 92 can be limited by the limiting blocks 94 to prevent the movable plate 92 from leaving the track 93. The movement of the rack 95 causes the gear 96 meshing with it to rotate synchronously. When the gear 96 rotates, it can drive the rotating shaft 97 fixed at its axis to rotate. When the rotating shaft 97 rotates, it can drive the screen cylinder 2 fixed at one end to flip. By rotating the bearing 98 on the outside of the rotating shaft 97 and fixing the bearing 98 in the support frame 99, since the support frame 99 is fixed to the top of the base plate 1, the stability of the rotating shaft 97 can be improved by the support of the support frame 99 and the bearing 98, thereby improving the stability of the screen cylinder 2 flipping.
[0028] Working principle: The worker feeds the material to be bundled into the top inlet of the screen cylinder 2. It is screened by the screen cylinder 2, and impurities are discharged from the filter screen 4. The material is discharged from the discharge chute 3. The screened impurities fall onto the inclined plate 7 and are discharged from the inclined plate 7 for collection. The material discharged from the discharge chute 3 falls onto the synchronous conveyor belt 83. The motor 81 starts and drives the first synchronous pulley 82 to rotate. The rotation of the first synchronous pulley 82 drives the synchronous conveyor belt 83 to rotate. When the synchronous conveyor belt 83 rotates, it transports the material on top of it to the bundling structure inside the bundling machine for bundling. When the screen cylinder 2 is not in use, the cylinder 91 can drive the moving plate 92 to move on the track 93. The movement of the moving plate 92 drives the rack 95 fixed on its top to move. The movement of the rack 95 drives the gear 96 meshing with it to rotate. The rotation of the gear 96 drives the rotating shaft 97 fixed at its center to rotate. The rotation of the rotating shaft 97 drives the screen cylinder 2 fixed at one end to flip, so that the bundling machine can pass smoothly through various height restriction sections.
