Description

Technical Field

[0001] The utility model relates to the technical field of round bale balers, in particular to a coupling mechanism with a torque converter. Background Technique

[0002] Round bale balers have a very wide range of applications. They can not only pick up and bale straw, wheat straw, cotton stalks, corn stalks, rape stalks, peanut vines, bean stalks, alfalfa, flax and other crop straws, but also be used for picking up and baling natural forage. When this equipment operates in the farmland, the power of the tractor is transmitted to each working component to complete the entire operation process from picking up, feeding, bundling, tying the bale to unloading the bale. The power of the pick-up of the round bale baler is transmitted by the feeding roller gear assembly through gears, shafts and chains.

[0003] At present, when most round bale balers are in use, due to the large differences in the working conditions of the fields in different regions, when the pick-up picks up forage in the fields of different environments and encounters hard objects other than crop straws (such as large stones, thick wooden sticks, iron rods), damage to the components of the baler may occur. Therefore, there are the following disadvantages: the problem of overload damage that may be encountered during the operation of the equipment, which reduces the service life of the machine, resulting in a decrease in the reliability and production efficiency of the equipment. Content of the Utility Model

[0004] The purpose of the utility model is to provide a coupling mechanism with a torque converter to solve the problem of overload damage that may be encountered during the operation of the equipment, which reduces the service life of the machine, resulting in a decrease in the reliability and production efficiency of the equipment.

[0005] To achieve the above-mentioned utility model purpose, the utility model adopts the following technical solutions: a coupling mechanism with a torque converter, including a pick-up assembly. One side of the pick-up assembly is provided with a feeding frame assembly. The feeding frame assembly is composed of a feeding tooth assembly, a double-row chain, a feeding chain and a sprocket shaft torque converter assembly. The sprocket shaft torque converter assembly is composed of a sprocket shaft body, a torque converter body and a sprocket body. Gears are respectively arranged on the pick-up assembly and the feeding frame assembly, and a pick-up chain is meshed between the gear on the pick-up assembly and the gear on the feeding frame assembly.

[0006] Preferably, two connecting plates are fixed on one side of the feeding frame assembly, and a plurality of first bolts are arranged on both of the two connecting plates.

[0007] Preferably, a fixing plate is arranged on the sprocket shaft torque converter assembly, and two second bolts are arranged on the fixing plate.

[0008] Preferably, washers are respectively arranged between the two second bolts and the fixing plate.

[0009] Preferably, the thickness of the washer is 50 mm.

[0010] Preferably, two lugs are fixed on one side of the feeding frame assembly.

[0011] Compared with the prior art, a coupling mechanism with a torque converter adopting the above technical solution has the following beneficial effects:

[0012] First, during use, through the pick-up assembly, feeding frame assembly, sprocket shaft torque converter assembly, and pick-up chain, when the equipment is subjected to excessive torque load, the transmission can be automatically disconnected, thereby protecting other mechanical components from damage, solving the problem of overload damage encountered during the operation of the equipment, improving the service life of the machine, thus enhancing the reliability and production efficiency of the equipment. At the same time, the structure is simple, easy to maintain, has strong environmental adaptability, is durable, reduces the requirements for high-precision and difficult-to-machine parts, is convenient for installation, and saves costs;

[0013] Second, during use, through the connecting plate and the first bolt, it is convenient for the staff to install the feeding frame assembly on the baler, which is easy to disassemble and assemble, improving the maintenance flexibility and operation convenience of the equipment. Through the fixing plate and the second bolt, it is convenient for the staff to disassemble and assemble the sprocket shaft torque converter assembly from the feeding frame assembly, facilitating the staff to perform maintenance or replacement, and facilitating the daily maintenance and component replacement work. Through the washer, not only the fastening property of the second bolt connection is increased, but also the loosening and wear of the second bolt are effectively prevented. During long-term use, the washer can disperse the stress received by the second bolt, protecting the second bolt and the connection surface from damage, ensuring the stability and safety of the sprocket shaft torque converter assembly;

[0014] Third, during use, by setting the thickness of the washer to 50 mm, it not only ensures sufficient compression to provide sufficient fastening force but also avoids problems such as insufficient installation space caused by excessive thickness or insufficient fastening force caused by too thin thickness. Through the lugs, it is convenient to provide additional fixing points and lifting points. During handling, installation, or maintenance, the staff can use the lugs to conveniently lift or fix the feeding frame assembly, improving the operation convenience and safety.

Detailed implementation mode

[0020] The following will, with reference to the accompanying drawings, elaborate on the preferred embodiments of the present utility model.

[0021] As Figures 1-4 shown, a coupling mechanism with a torque converter includes a pickup assembly 1. On one side of the pickup assembly 1, there is a feeding frame assembly 2. The feeding frame assembly 2 consists of a feeding tooth assembly 201, a double-row chain 202, a feeding chain 203, and a sprocket shaft torque converter assembly 3. The sprocket shaft torque converter assembly 3 consists of a sprocket shaft body 301, a torque converter body 302, and a sprocket body 303. Gears are respectively provided on the pickup assembly 1 and the feeding frame assembly 2, and a pickup chain 4 is meshed between the gears of the pickup assembly 1 and the feeding frame assembly 2.

[0022] During use, the staff first assemble the sprocket shaft body 301, the torque converter body 302, and the sprocket body 303 into the sprocket shaft torque converter assembly 3. Then, assemble the feeding tooth assembly 201, the double-row chain 202, the feeding chain 203, and the sprocket shaft torque converter assembly 3 into the feeding frame assembly 2. Then, connect the pickup assembly 1 and the feeding frame assembly 2 at fixed positions, and hang the pickup chain 4 between the pickup assembly 1 and the feeding frame assembly 2. When in use, the drive shaft drives the feeding tooth assembly 201 to rotate. The feeding tooth assembly 201 drives the sprocket shaft torque converter assembly 3, and then transmits it to the pickup assembly 1 through the feeding chain 203 and the pickup chain 4. When the pickup assembly 1 encounters excessive resistance (such as when the pickup hits a stone, a large thick wooden stick, an iron rod, etc.), the pickup assembly 1 will stop rotating, while the transmission box keeps rotating. At this time, the sprocket shaft torque converter assembly 3 slips, protecting the entire mechanism from damage. At the same time, a double-row chain 202 is used to connect the sprocket shaft torque converter assembly 3 and the feeding tooth assembly 201. The double-row chain 202 can not only compensate for the axial clearance but also reduce the coaxiality requirements between the feeding tooth assembly 201 and the sprocket shaft torque converter assembly 3, thus reducing the processing difficulty of the feeding frame assembly 2, the feeding tooth assembly 201, and the sprocket shaft body 301.

[0023] Through the picker assembly 1, the feeding rack assembly 2, the sprocket shaft torque converter assembly 3, and the pick-up chain 4, when the equipment is subjected to excessive torque load, the transmission can be automatically disconnected, thus protecting other mechanical components from damage, solving the problem of overload damage encountered during the operation of the equipment, improving the service life of the machine, thereby enhancing the reliability and production efficiency of the equipment. At the same time, the structure is simple and easy to maintain, has strong environmental adaptability, is durable, reduces the requirements for high-precision and difficult-to-machine parts, is convenient for installation, and saves costs.

[0024] As Figures 1-3 shown, two connecting plates 5 are fixed on one side of the feeding rack assembly 2, and a number of first bolts 6 are provided on both connecting plates 5.

[0025] During use, through the connecting plates 5 and the first bolts 6, it is convenient for the staff to install the feeding rack assembly 2 on the baler, which is convenient for disassembly and assembly, improving the maintenance flexibility and operation convenience of the equipment.

[0026] As Figure 2 and Figure 4 shown, a fixing plate 7 is provided on the sprocket shaft torque converter assembly 3, and two second bolts 8 are provided on the fixing plate 7. Washers 9 are respectively provided between the two second bolts 8 and the fixing plate 7.

[0027] During use, through the fixing plate 7 and the second bolts 8, it is convenient for the staff to disassemble and assemble the sprocket shaft torque converter assembly 3 from the feeding rack assembly 2, facilitating maintenance or replacement by the staff and facilitating daily maintenance and component replacement work. Through the washer 9, not only the fastening property of the connection of the second bolt 8 is increased, but also the loosening and wear of the second bolt 8 are effectively prevented. During long-term use, the washer 9 can disperse the stress received by the second bolt 8, protecting the second bolt 8 and the connection surface from damage, ensuring the stability and safety of the sprocket shaft torque converter assembly 3.

[0028] As Figures 1-4 shown, the thickness of the washer 9 is 50 mm, and two lugs 10 are fixed on one side of the feeding rack assembly 2.

[0029] During use, setting the thickness of the washer 9 to 50 mm not only ensures sufficient compression to provide sufficient fastening force, but also avoids problems such as insufficient installation space caused by excessive thickness or insufficient fastening force caused by too thin thickness. Through the lugs 10, it is convenient to provide additional fixing points and lifting points. During handling, installation or maintenance, the staff can use the lugs 10 to conveniently lift or fix the feeding rack assembly 2, improving the operation convenience and safety.

[0030] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
