Description

Technical Field

[0001] This utility model relates to the field of round hay bale baling technology, specifically to a round hay bale baling device. Background Technology

[0002] A round hay bale baler is a type of machinery used in agricultural production. It is mainly used to bale harvested hay, such as pasture and straw, into round bales for easy storage, transportation, and use. The machine collects scattered hay through a high-speed rotating feed roller at the front end, compresses it into a cylindrical bale, and then secures it with ropes, nets, or other binding methods to complete the bale formation. However, because the feed roller rotates at high speed, the friction between the shaft used to fix the feed roller and the bearing is relatively large. Long-term operation will lead to bearing wear. As friction increases, the bearing will gradually wear out, which will affect the normal operation of the bearing and may even cause the bearing to be damaged, thus affecting the overall performance of the equipment.

[0003] In view of this, we propose a round hay bale baling device. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a round bale baling device, which can effectively solve the problem that friction between the shaft and bearing during the high-speed rotation of the feed roller in the existing technology will lead to bearing wear and affect the overall performance of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a round bale baling device, including a frame and a feeding roller arranged inside the frame. A fixed shaft is fixedly installed on the inner cavity side wall of the feeding roller, and two sets of sealed bearings are rotatably installed on the surface of the fixed shaft. The side of the two sets of sealed bearings away from the feeding roller is fixedly installed on the inner cavity side wall of the frame.

[0007] Both sets of sealed bearings are fixedly connected to connecting pipes. Both sets of connecting pipes are equipped with drive components at the ends away from the sealed bearings, and the drive components are also located at both ends of the fixed shaft.

[0008] Furthermore, the drive assembly includes a first small synchronous pulley and a second small synchronous pulley that are fixedly mounted at both ends of a fixed shaft, with the side of the second small synchronous pulley away from the fixed shaft rotatably mounted on the inner wall of the frame.

[0009] A motor is fixedly installed at the bottom of the inner cavity of the frame, and the motor is fixedly installed on the side of the first small synchronous pulley away from the fixed shaft via the output shaft.

[0010] Furthermore, the surfaces of the first and second small synchronous pulleys are both connected to large synchronous pulleys by synchronous toothed belts, and the sides of the two sets of large synchronous pulleys that are close to each other are rotatably mounted on the inner cavity sidewall of the frame.

[0011] Furthermore, cranks are fixedly connected to the sides of the two sets of large synchronous pulleys that are far apart from each other, and connecting rods are rotatably mounted on the ends of the two sets of cranks that are far apart from the large synchronous pulleys, and piston rods are rotatably mounted on the ends of the two sets of connecting rods that are far apart from the cranks.

[0012] Furthermore, rubber pistons are fixedly connected to the ends of both sets of piston rods away from the connecting rod, and piston cylinders are fitted onto the surfaces of both sets of rubber pistons.

[0013] Furthermore, the surfaces of both sets of piston cylinders are fixedly installed on the inner cavity sidewall of the frame, and the bottoms of both sets of piston cylinders are fixedly connected to the end of the connecting pipe away from the sealing bearing.

[0014] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0015] This invention, by installing connecting pipes on two sets of sealed bearings and utilizing a drive component at one end of the connecting pipes, allows for the injection of lubricating oil into the two sets of sealed bearings during the high-speed rotation of the feed roller for conveying forage. The injected lubricating oil is then drawn out and repeated, ensuring even distribution of lubricating oil within the sealed bearings. This lubrication reduces friction between the sealed bearings and the fixed shaft, thereby minimizing bearing wear and damage during prolonged operation and effectively extending the overall service life of the equipment.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] A round hay bale baling device includes a frame 1 and a feeding roller 2 disposed inside the frame 1. A fixed shaft 11 is fixedly installed on the inner side wall of the feeding roller 2, and two sets of sealed bearings 3 are rotatably installed on the surface of the fixed shaft 11. The side of the two sets of sealed bearings 3 away from the feeding roller 2 is fixedly installed on the inner side wall of the frame 1. A connecting pipe 14 is fixedly connected to the surface of the two sets of sealed bearings 3. A drive assembly is provided at the end of the two sets of connecting pipes 14 away from the sealed bearings 3. The drive assembly is also disposed at both ends of the fixed shaft 11. The surface of the two sets of piston cylinders 10 is fixedly installed on the inner side wall of the frame 1, and the bottom of the two sets of piston cylinders 10 is fixedly connected to the end of the connecting pipe 14 away from the sealed bearings 3.

[0025] Specifically, by setting connecting pipes 14 on the two sets of sealed bearings 3, and using the drive component at one end of the connecting pipe 14, when the feed roller 2 is rotating at high speed to convey the forage, the connecting pipes 14 connected by the two sets of piston cylinders 10 can be used to inject lubricating oil into the two sets of sealed bearings 3, and to draw out the injected lubricating oil again. The sealed bearings 3 use high-efficiency shaft seals and sealing rings, which can ensure that the return flow of lubricating oil is not affected. By repeating this process, the lubricating oil can be evenly distributed into the interior of the sealed bearings 3, thereby lubricating the sealed bearings 3, reducing the friction between the sealed bearings 3 and the fixed shaft 11, and thus reducing the wear and damage of the sealed bearings 3 during long-term operation, which can effectively improve the overall service life of the equipment.

[0026] Specifically, the drive assembly includes a first small synchronous pulley 4 and a second small synchronous pulley 12 fixedly mounted at both ends of a fixed shaft 11. The side of the second small synchronous pulley 12 away from the fixed shaft 11 is rotatably mounted on the inner cavity sidewall of the frame 1. A motor 5 is fixedly mounted at the bottom of the inner cavity of the frame 1, and the motor 5 is fixedly mounted on the side of the first small synchronous pulley 4 away from the fixed shaft 11 via an output shaft. The surfaces of the first small synchronous pulley 4 and the second small synchronous pulley 12 are both connected to a large synchronous pulley 7 by a synchronous toothed belt 6. The sides of the two sets of large synchronous pulleys 7 that are close to each other are rotatably mounted on the inner cavity sidewall of the frame 1. The sides of the two sets of large synchronous pulleys 7 that are far from each other are fixedly connected to a crank 8. The ends of the two sets of cranks 8 that are far from the large synchronous pulleys 7 are rotatably mounted to a connecting rod 9, and the ends of the two sets of connecting rods 9 that are far from the cranks 8 are rotatably mounted to a piston rod 13. The ends of the two sets of piston rods 13 that are far from the connecting rods 9 are fixedly connected to a rubber piston 15, and the surfaces of the two sets of rubber pistons 15 are fitted with piston cylinders 10.

[0027] Specifically, the motor 5 inside the frame 1 outputs power to drive the first small synchronous pulley 4, which is fixedly connected to one end of the fixed shaft 11, to rotate. The fixed shaft 11 drives the feed roller 2 on the surface to rotate, thus conveying the forage. It also drives the second small synchronous pulley 12 at the other end of the fixed shaft 11 to rotate. At the same time, two sets of synchronous toothed belts 6 drive two sets of large synchronous pulleys 7 to rotate. Then, the crank 8 and connecting rod 9 connected to the large synchronous pulleys 7 drive the piston rod 13 inside the piston cylinder 10 to repeatedly move up and down. The rubber piston 15 inside the piston cylinder 10 can repeatedly inject lubricating oil into the sealed bearing 3, and after injection, the lubricating oil is drawn back into the piston cylinder 10.

[0028] The working principle of this utility model is as follows: The motor 5 inside the frame 1 outputs power, driving the first small synchronous pulley 4 fixedly connected to one end of the fixed shaft 11 to rotate. The fixed shaft 11 then drives the feed roller 2 on its surface to rotate, thus conveying the forage. Simultaneously, it drives the second small synchronous pulley 12 at the other end of the fixed shaft 11 to rotate. At the same time, two sets of synchronous toothed belts 6 drive two sets of large synchronous pulleys 7 to rotate. Furthermore, the crank 8 and connecting rod 9 connected to the large synchronous pulleys 7 drive the piston rod 13 inside the piston cylinder 10 to repeatedly move up and down, thereby utilizing… The rubber piston 15 inside the piston cylinder 10 can repeatedly inject lubricating oil into the sealed bearing 3, and after injection, the lubricating oil can be drawn back into the piston cylinder 10. The sealed bearing 3 uses a high-efficiency shaft seal and sealing ring, which can ensure that the return flow of lubricating oil is not affected. By repeating this process, the lubricating oil can be evenly distributed inside the sealed bearing 3, thereby lubricating the sealed bearing 3, reducing the friction between the sealed bearing 3 and the fixed shaft 11, and thus reducing the wear and damage of the sealed bearing 3 during long-term operation. Consequently, it can effectively improve the overall service life of the equipment.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
