Description

Technical Field

[0001] The invention relates to an assembly structure of a granary chain box and a transmission box body. Background Art

[0002] In the existing structure, there is a long gap between the transmission case and the chain box, which leads to multiple problems. In order to ensure the normal operation of the transmission system and extend its service life, it is usually necessary to install a spacer to fill the gap. In addition, 6205 bearings are also required to be installed at the welded part between the chain box and the transmission case to protect the transmission shaft and reduce its vibration. Although this design can solve the vibration problem to a certain extent, it brings higher assembly costs and subsequent maintenance costs.

[0003] In traditional designs, the runout problem of the drive shaft needs to be corrected by adding bearings, which not only increases the cost of purchasing bearings, but also requires additional adjustments and inspections during the assembly process. In addition, the use of spacers further increases the difficulty and cost of production and the complexity of the system. In the long-term use process, the maintenance and replacement of these additional components also requires an increase in the maintenance frequency of the equipment, further increasing the operating and maintenance costs.

[0004] The existing structure uses a spacer to position the transmission shaft of the transmission box and the oil seal, which results in an additional spacer when the transmission shaft is connected to the oil seal. As a result, there is a gap between the spacer and the transmission shaft, which causes some shaking when the oil seal and the spacer are assembled, thereby causing the risk of oil leakage from the oil seal. Summary of the invention

[0005] The purpose of the present invention is to solve the above deficiencies in the prior art and to provide an assembly structure for a granary chain box and a transmission case.

[0006] A granary chain box and transmission box assembly structure comprises a box body and a housing, wherein the box body is provided with a connecting port, a connecting seat with a hollow structure is provided at the connecting port, a connecting part is provided at the front end of the housing, an outer side surface of the connecting seat is fixedly connected to an inner side surface of the connecting port, and an outer side surface of the connecting part is detachably connected to an inner side surface of the connecting seat.

[0007] Furthermore, a first sprocket and a second sprocket are provided inside the box body, and the first sprocket and the second sprocket are driven by a chain. The first sprocket is installed on the grain discharge auger shaft, and the second sprocket is installed on the transmission shaft, and the transmission shaft is installed in the box body.

[0008] Furthermore, the transmission shaft is rotatably connected in the housing through at least two bearings, and a bevel gear is provided on the transmission shaft.

[0009] Furthermore, the connecting portion and the connecting socket are plugged into each other.

[0010] Furthermore, an outer circular structure is provided on the outer side surface of the connecting portion.

[0011] Furthermore, the outer side surface of the connecting seat is provided with an outer circular structure.

[0012] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0013] Eliminate assembly gaps: By adopting the design of threaded connection and outer circular structure, the box body and the box can be precisely connected together, eliminating the assembly gaps between the two. This tight connection not only enhances the stability of the connection but also improves the overall assembly accuracy, ensuring that there are no loosening or gap problems caused by improper assembly during use.

[0014] Enhance the stability of the connection: The threaded connection provides a strong fastening force, which can effectively resist external tensile force and torque. The coordinated design of the outer circular structure further improves the contact surface accuracy, making the connection more stable and reliable, and avoiding the problems of loose connection or deviation that may occur in traditional connection methods.

[0015] Facilitate disassembly and maintenance: The threaded connection method of this structure not only ensures the stability of the connection but also has good disassembly performance. During the repair or replacement of the equipment, the operator only needs to rotate the connecting part to easily disassemble it, saving maintenance time and labor costs and improving the maintainability of the equipment.

[0016] Improve transmission efficiency and reliability: Through the cooperation of the sprocket, chain and transmission shaft, the transmission system can efficiently transmit power to the grain bin chain box to ensure the stable operation of the system. The bevel gear on the transmission shaft further optimizes the transmission of speed and power, improving the transmission efficiency and durability of the system.

[0017] Strong adaptability: The threaded connection and outer circular structure design adopted in the present invention enable this structure to adapt to different models or specifications of grain bin chain boxes and transmission boxes, with strong adaptability and versatility, and can meet the requirements of different application scenarios.

[0022] To deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0023] An assembly structure of a grain bin chain box and a transmission box body includes a box body 1 and a box body 2. The connection between the box body 1 and the box body 2 adopts the design of a connection port and a connection seat 3. A connection port is provided on the side of the box body 1, and a connection seat 3 with a hollow structure is provided on the inner side of the connection port. A connection portion 4 is provided at the front end of the box body 2. The outer side surface of the connection seat 3 is connected to the inner side surface of the connection port by a fixing method, and the outer side surface of the connection portion 4 is connected to the inner side surface of the connection seat 3 by a threaded connection or other detachable connection methods. This design ensures the stable connection of the grain bin chain box and the transmission box body 2, and at the same time can be conveniently disassembled and replaced when needed.

[0024] A first sprocket and a second sprocket are provided inside the box body 1, and power is transmitted between the first sprocket and the second sprocket through a chain. The first sprocket is installed on the grain discharging auger shaft, and the second sprocket is installed on the transmission shaft, and the transmission shaft is installed in the box body 2. The transmission shaft is rotatably connected in the box body 2 through at least two bearings. The function of the bearings is to ensure the stable rotation of the transmission shaft and reduce friction and wear. Through the cooperation of the sprockets and the chain, efficient power transmission of the grain bin chain box can be achieved, ensuring the continuous and stable operation of the grain bin during operation.

[0025] A bevel gear is provided on the transmission shaft, and the bevel gear is used to cooperate with other transmission components to achieve speed and power transmission between different axes. The use of the bevel gear can improve the transmission efficiency of the system, and at the same time enhance the stability and durability of the system.

[0026] Threads are provided on both the outer side surface of the connection portion 4 and the inner side surface of the connection seat 3. The box body 1 and the box body 2 are tightly fixed through the threaded connection portion 4 and the connection seat 3, thereby avoiding loosening during use. The threaded connection also provides high disassembly convenience, facilitating the maintenance and repair of the equipment. Outer circular 5 structures are respectively provided on the outer side surfaces of the connection portion 4 and the connection seat 3. The design of the outer circular 5 structure strengthens the contact surface and improves the connection accuracy, thereby ensuring a more stable connection.

[0027] Working principle: Replacing the original separate assembly structure of the box body 1 and the box body 2, in this embodiment, the box body 1 and the box body 2 are assembled together through the connection portion 4 and the connection seat 3. The connection between the connection portion 4 and the connection seat 3 is mainly achieved through the cooperation of a threaded connection and the outer circular 5 structure.

[0028] The connection portion and the connection seat are inserted.

[0029] The outer circle 5 structure further enhances the mating accuracy between the connecting part 4 and the connecting seat 3. The outer side surfaces of both the connecting part 4 and the connecting seat 3 are provided with the outer circle 5 structure. This design enables the connecting part 4 and the connecting seat 3 to be accurately docked during assembly, reducing the errors caused by improper assembly. The outer circle 5 structure not only increases the connecting contact surface but also improves the connection stability, preventing the connection from loosening due to vibration or external force during the working process.

[0030] The cooperation of the thread and the outer circle 5 structure makes the entire connection structure more firm, stable, and has better anti-vibration performance. In this way, the connection between the grain bin chain box and the transmission box body 2 can withstand greater working loads and ensure reliability during long-term use.

[0031] In addition, due to the existence of the threaded connection method, users can very conveniently disassemble the connecting part 4 when disassembly or maintenance is required, without special tools or complex operations. This design improves the maintainability and usability of the equipment.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
