Description

Technical Field

[0001] This utility model relates to baling machines, specifically to a double-outlet square baling machine and a dual-shaft transmission structure. Background Technology

[0002] Balers are the best-selling agricultural equipment for baling straw or hay in my country. Although the balers currently in use, especially square balers, have high baling efficiency, they can only bale one channel at a time, which cannot achieve higher baling efficiency.

[0003] To improve baling efficiency, the applicant developed a double-outlet bundling and knotting type square baler, which effectively improves baling efficiency by using two baling mechanisms in cooperation. This technical solution was filed on November 18, 2024, and authorized on January 3, 2025, with authorization announcement number CN222284028U. While this technical solution effectively improves baling efficiency, it still has drawbacks such as a complex transmission structure, a large number of transmission components leading to high costs, and limitations in widespread application. To address these issues, this patent provides a novel double-outlet square baler. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a double-outlet square baler that can improve baling efficiency while increasing the cost within a limited range, and ensure stable transmission between the various transmission components.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a double-outlet square baler, comprising a gearbox, a transmission mechanism, and a baling mechanism. The gearbox has two power output shafts, each connected to a transmission mechanism. The transmission mechanism includes a crank and an intermediate transmission shaft, with a transmission connection part on the intermediate transmission shaft and a piston connection part on the crank. The power output shafts drive the crank and the power output shaft to rotate. There are two baling mechanisms, respectively located on both sides of the gearbox. The pistons of the baling mechanisms are connected to the piston connection parts, and the transmission system of the baling mechanisms is engaged with the transmission connection parts. Both power output shafts of the gearbox are equipped with transmission mechanisms, and the two baling mechanisms are distributed on both sides of the gearbox. The gearbox transmits power to the two baling mechanisms through the transmission mechanisms, driving the two baling mechanisms to work.

[0006] As an optional solution of this utility model, the transmission system of the bundling mechanism is set externally, the intermediate transmission shaft is set on the bundling mechanism and rotates relative to the bundling mechanism, and one end of the intermediate transmission shaft extends out of the bundling mechanism and is provided with a transmission connection part.

[0007] As an optional solution of this utility model, the power output shaft is connected to the crank, the intermediate transmission shaft is coaxial with the power output shaft and a connecting handle is provided on the intermediate transmission shaft, and the connecting handle is connected to the piston connection part.

[0008] As an optional solution of this utility model, the two bundling mechanisms are symmetrically distributed.

[0009] As an optional solution of this utility model, an installation gap is reserved between the two bundling mechanisms, the width of which is no more than 600mm, and the gearbox is set within the installation gap. The gap between the bundling mechanisms being no more than 600mm helps to improve the overall structural stability of the equipment.

[0010] As an optional solution of this utility model, the two bundling mechanisms are provided with clearance grooves on their opposite side end faces, the two bundling mechanisms are fitted together and the two clearance grooves are connected to form a clearance cavity, and the gearbox is set in the clearance cavity.

[0011] As an optional solution of this utility model, it also includes a picking mechanism, with the two bundling mechanisms sharing one picking mechanism.

[0012] As an optional solution of this utility model, a diversion plate is provided between the feeding inlets of the two bundling mechanisms in the picking mechanism.

[0013] Based on the same concept, this utility model also provides a dual-shaft transmission structure, including a gearbox. The gearbox has two power output shafts, and both power output shafts are connected to a transmission mechanism. The transmission mechanism includes a crank and an intermediate transmission shaft. The crank is connected to the power output shaft and has a piston connecting part. The intermediate transmission shaft is coaxial with the power output shaft and is connected to the piston connecting part through a connecting handle. The intermediate transmission shaft has a transmission connecting part.

[0014] The gearbox has power output shafts on opposite sides, and the two transmission mechanisms are symmetrically distributed.

[0015] Compared with the prior art, the advantages of this utility model are as follows: 1. The baling machine of this utility model includes two baling mechanisms, which can effectively improve the baling speed and efficiency. A single gearbox drives both baling mechanisms, and both power output shafts of the gearbox are equipped with transmission mechanisms. The transmission mechanisms are connected to the pistons and transmission systems of the baling mechanisms, allowing the gearbox to drive the various components of the baling mechanisms through a single power output shaft. 2. The distance between the two baling mechanisms is 0-600mm. When the distance is small, a clearance groove is provided on the housing of the baling mechanism to allow the gearbox to be installed between the two baling mechanisms and stably drive them. 3. The two baling mechanisms share a single transmission box. The two baling mechanisms are symmetrically distributed, and the two transmission mechanisms are symmetrically distributed. The conditions on both power output sides of the transmission box are consistent, which can prevent radial offset of the power output shaft, thereby avoiding wear of the gearbox after prolonged use.

[0021] 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. Example

[0022] like Figure 1 and Figure 2 As shown, a double-outlet square baler includes a gearbox 1, a transmission mechanism, and baling mechanisms 8. The gearbox 1 is a gearbox for the baler, having one power input shaft and two power output shafts 2. The two power output shafts 2 are symmetrically arranged on opposite sides of the gearbox 1, and each power output shaft 2 is connected to a transmission mechanism. There are two baling mechanisms 8, each located on one side of the gearbox 1. The gearbox 1 drives the two baling mechanisms 8 respectively through the two transmission mechanisms. Alternatively, the gearbox 1 can have a single power output shaft, with both ends extending from opposite sides of the gearbox 1 and connected to a transmission mechanism.

[0023] The transmission mechanism includes a crank 3 and an intermediate transmission shaft 6. A piston connecting part 4 is provided on the crank 3, which connects to the piston of the compression component in the baling mechanism 8. A transmission connecting part 7 is provided on the intermediate transmission shaft 6, which engages with the transmission system of the baling mechanism 8. The transmission connecting part 7 can be in the form of a gear, sprocket, etc. During the rotation of the crank 3 and intermediate transmission shaft 6 driven by the power output shaft 2, the crank 3 rotates, causing the piston of the baling mechanism 8 to reciprocate. The intermediate transmission shaft 6 rotates, causing the various components of the transmission system to rotate, thus enabling the baling mechanism 8 to work and compress and bale hay, straw, etc.

[0024] The two bundling mechanisms 8 are symmetrically arranged, and their transmission systems are located externally, specifically on the side furthest from each other. This external location facilitates maintenance and repair. The power output shaft 2 is connected to the crank 3, directly driving the crank 3 to rotate. The intermediate transmission shaft 6 is mounted on the bundling mechanism 8 via a bearing mounting structure. The intermediate transmission shaft 6 is coaxial with the power output shaft 2 and is rotatable. A connecting handle 5 is provided on the intermediate transmission shaft 6, connecting to the piston connection part 4. The power output shaft 2 drives the intermediate transmission shaft 6 to rotate by rotating the crank 3. One end of the intermediate transmission shaft 6 extends outside the bundling mechanism 8, and a transmission connection part 7 is provided on the intermediate transmission shaft 6 at the corresponding transmission system location.

[0025] The transmission systems of the two baling mechanisms 8 can also be located internally, i.e., the transmission systems of the two baling mechanisms 8 are located on the side of the two baling mechanisms 8 that are close to each other. In this case, the intermediate transmission shaft 6 is mounted on the baling mechanism 8 through a bearing mounting structure. The intermediate transmission shaft 6 is coaxial with the power output shaft 2 and is directly connected to the power output shaft 2. A transmission connection part 7 is provided on the intermediate transmission shaft 6 at the corresponding transmission system position. A crank 3 is provided on the intermediate transmission shaft 6 at the position corresponding to the piston of the baling mechanism 8. A piston connection part 4 is provided on the crank 3 and is connected to the piston. The power output shaft 2 drives the intermediate transmission shaft 6 to rotate and drives the crank 3 to rotate through the intermediate transmission shaft 6.

[0026] This utility model discloses a double-outlet square baler, which uses a gearbox 1 to drive two baling mechanisms 8. Compared with a baler of the same specifications with a single baling mechanism 8, the cost increase is limited, but the baling efficiency is significantly improved. Moreover, apart from sharing a gearbox 1, the other components of the two balers are independent of each other.

[0027] The double-outlet square baler of this utility model also includes a necessary walking frame, and the gearbox 1 and the baling mechanism 8 are set on the walking frame.

[0028] In some embodiments, the bundling mechanism 8 is mounted on the walking frame and an installation gap is reserved between the two bundling mechanisms 8. The gearbox 1 is mounted within the installation gap. The width of the installation gap is adaptively adjusted according to the size and specifications of the gearbox 1. In order to ensure the overall structural stability of the equipment and the transmission effect between the mechanisms, the installation gap is no more than 600mm.

[0029] In other embodiments, the two bundling mechanisms 8 are provided with clearance grooves on their opposite side end faces. Specifically, the clearance grooves are provided on the housing of the bundling mechanism 8. When the two bundling mechanisms 8 are fitted together or when they are close enough that the gap is insufficient to install the gearbox 1, the two clearance grooves are joined to form a clearance cavity. The gearbox 1 is installed in the clearance cavity. The housing of the bundling mechanism 8 is provided with clearance holes at the clearance grooves for the transmission components such as the power output shaft 2 to pass through.

[0030] The double-outlet square baler of this utility model also includes a picking mechanism 9. The two baling mechanisms 8 can each be equipped with a picking mechanism 9, or they can share a single picking mechanism 9. When the two baling mechanisms 8 share a single picking mechanism 9, a diversion plate 10 is provided inside the picking mechanism 9 between the feeding inlets of the two baling mechanisms. Under the action of the diversion plate 10, the hay, straw, etc. picked up by the picking mechanism 9 can be fed into the two baling mechanisms 8 for baling. Example

[0031] like Figure 2 and Figure 3 As shown, a dual-shaft transmission structure includes a gearbox 1. The gearbox 1 has two power output shafts 2, and both power output shafts 2 are connected to a transmission mechanism. The transmission mechanism includes a crank 3 and an intermediate transmission shaft 6. The crank 3 is connected to the power output shafts 2, and a piston connecting part 4 is provided on the crank 3. The intermediate transmission shaft 6 is coaxial with the power output shafts 2, and the intermediate transmission shaft 6 is connected to the piston connecting part 4 through a connecting handle 5. A transmission connecting part 7 is provided on the intermediate transmission shaft 6.

[0032] The gearbox 1 has power output shafts 2 on opposite sides, and the two transmission mechanisms are symmetrically distributed. The symmetrical distribution of the two transmission mechanisms can avoid wear between the internal components of the gearbox 1 due to radial offset of the power output shafts 2, which helps to extend the service life of the gearbox 1.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
