Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of assembly structure of granary chain box and transmission box. BACKGROUND

[0002] In the existing structure, there is a long gap between the transmission box and the chain box. This design leads to multiple problems. To ensure the normal operation of the transmission system and prolong the service life, a spacer sleeve is usually added to fill the gap. In addition, a 6205 bearing needs to be added to the welded part of the chain box and the transmission box to protect the transmission shaft and reduce its runout. Although this design can solve the runout problem to some extent, it brings higher assembly cost and subsequent maintenance cost.

[0003] In traditional design, the runout problem of the transmission shaft needs to be corrected by adding a bearing, which not only increases the procurement cost of the bearing, but also requires additional adjustment and inspection during assembly. In addition, the use of a spacer sleeve further increases the production difficulty and cost, and also increases the complexity of the system. During long-term use, the maintenance and replacement of these additional components also require increased maintenance frequency of the equipment, further increasing operating and repair costs.

[0004] The existing structure causes the transmission shaft of the transmission box to have an additional spacer sleeve when connecting with the oil seal, which causes some movement when the oil seal and the spacer sleeve are assembled due to the gap between the spacer sleeve and the transmission shaft, thereby increasing the risk of oil leakage of the oil seal. INVENTION CONTENTS

[0005] The utility model aims to solve the above problems of the prior art and provides an assembly structure of a granary chain box and a transmission box.

The box body is provided with a connecting port, and the connecting port is provided with a connecting seat with a hollow structure. The front end of the box body is provided with a connecting part. The outer side surface of the connecting seat is fixedly connected to the inner side surface of the connecting port, and the outer side surface of the connecting part is detachably connected to the inner side surface of the connecting seat.

[0007] Further, the box body is provided with a first sprocket and a second sprocket. The first sprocket and the second sprocket are connected by a chain. The first sprocket is installed on the discharge auger shaft, and the second sprocket is installed on the transmission shaft. The transmission shaft is installed in the box body.

[0008] Further, the transmission shaft is rotatably connected to the box body by at least two bearings. The transmission shaft is provided with a bevel gear.

[0011] Further, the outer side of the connecting seat is provided with an outer circle structure.

[0012] Beneficial effects: Compared with the prior art, the utility model has the following advantages:

[0013] Eliminate assembly gap: by adopting the design of threaded connection and outer circle structure, the box body and the box body can be connected together accurately, and the assembly gap between the two is eliminated. This close connection not only enhances the stability of the connection, but also improves the accuracy of the overall assembly, ensuring that there is no looseness or gap problem caused by improper assembly during use.

[0014] Strengthen the stability of the connection: threaded connection provides strong fastening force, which can effectively resist external tension and torque. The matching design of the outer circle structure further improves the contact surface accuracy, making the connection more stable and reliable, avoiding the connection not tight or deviation problem that may occur in traditional connection method.

[0015] Convenient to disassemble and maintain: the threaded connection method of the structure not only can ensure the stability of the connection, but also has good dismountability. During the maintenance or replacement of the equipment, the operator only needs to rotate the connecting part to easily disassemble, saving maintenance time and labor cost, and improving the maintainability of the equipment.

[0016] Improve the transmission efficiency and reliability: through the cooperation of the chain wheel, chain and transmission shaft, the transmission system can efficiently transmit power to the grain storehouse chain box, ensuring 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 circle structure design adopted by the utility model makes the structure adapt to different models or specifications of grain storehouse chain boxes and transmission boxes, has strong adaptability and universality, and can meet the needs of different application scenarios.
