[0024] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0025] The present utility model provides a straw round bale baler packing roller as shown in Figures 1 to 5 the figure, including:

[0026] A roller main body 1, both ends of the roller main body 1 are provided with threaded heads 2, and the roller main body 1 and the threaded heads 2 are integrally processed and formed, so that the connection strength between the roller main body 1 and the threaded heads 2 is large, and it is convenient for processing and forming. A cavity 3 is opened in the middle of the roller main body 1, and both ends of the cavity 3 extend to the ends of the threaded heads 2, and a plurality of limit grooves 4 are opened on the inner wall of the cavity 3 at equal arc lengths;

[0027] A transmission shaft assembly 5, the number of the transmission shaft assemblies 5 is set to two, and the two transmission shaft assemblies 5 are respectively located at both ends of the roller main body 1. The transmission shaft assembly 5 includes a roller shaft 6, and a limit insertion post 7 is fixed at one end of the roller shaft 6 close to the roller main body 1. A plurality of limit blocks 8 are arranged on the surface of the limit insertion post 7 at equal arc lengths. An internal thread sleeve 9 is rotatably sleeved on the roller shaft 6 through a bearing. The internal thread sleeve 9 is sleeved on the limit insertion post 7, and the internal thread sleeve 9 is threadedly connected with the threaded head 2. The internal thread sleeve 9 is threadedly sleeved on the threaded head 2 to realize the connection between the transmission shaft assembly 5 and the roller main body 1, which is fast and convenient for connection and easy to disassemble at the same time.

[0028] The limit insertion post 7 is matched with the cavity 3, and the limit block 8 is matched with the limit groove 4. When the limit insertion post 7 is inserted into the cavity 3, the limit block 8 is driven to be inserted into the corresponding limit groove 4, so that when the transmission shaft assembly 5 rotates, the roller main body 1 can be driven to rotate.

[0029] A plurality of convex blocks 10 are fixed at equal intervals on the outer side of the internal thread sleeve 9. The convex blocks 10 can increase the friction between the hand and the internal thread sleeve 9, so that the force acts on the internal thread sleeve 9, which is convenient for rotating the internal thread sleeve 9.

[0030] The roller shaft 6 and the limit insertion post 7 are integrally processed and formed, so that the connection strength between the roller shaft 6 and the limit insertion post 7 is high, and it is convenient for processing and forming.

[0031] A plurality of convex strips 11 are fixedly arranged on the outer side of the roller body 1 at equal arc lengths. The convex strips 11 correspond to the limit grooves 4, which increases the friction between the roller body 1 and the straw, and facilitates the roller body 1 to push the straw to move when rotating.

[0032] In the present utility model, when the transmission shaft assembly 5 is connected to the roller body 1, the limit insertion post 7 on the transmission shaft assembly 5 is aligned with the cavity 3 on the roller body 1, and the limit block 8 on the limit insertion post 7 is aligned with the limit groove 4 on the inner wall of the cavity 3. The limit insertion post 7 is inserted into the cavity 3, and the limit block 8 thereon is driven to be inserted into the corresponding limit groove 4, so that when the transmission shaft assembly 5 rotates, it can drive the roller body 1 to rotate. Then, the internal thread sleeve 9 is rotated, so that the internal thread sleeve 9 is threadedly sleeved on the thread head 2, realizing the connection between the transmission shaft assembly 5 and the roller body 1. The connection is quick and convenient. When disassembling, the internal thread sleeve 9 is rotated in the reverse direction, so that the internal thread sleeve 9 is disengaged from the thread head 2, and then the transmission shaft assembly 5 is pulled in a direction away from the roller body 1, and the transmission shaft assembly 5 can be separated from the roller body 1. The disassembly is convenient, and the disassembly and assembly between the transmission shaft assembly 5 and the roller body 1 are quick and convenient, saving time and effort.

[0033] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
