[0019] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1 to 3 The utility model provides a technical solution: a baling device in the cavity of a round baler, comprising: a steel roller 1, a plug-in groove 2 is opened on the surface of the steel roller 1, a plug-in base 3 is movably plugged into the plug-in groove 2, a rubber strip 4 is fixed on the surface of the plug-in base 3, one end of the rubber strip 4 extends from the plug-in groove 2, and the plug-in groove 2 is provided in a plurality of groups, and the plurality of groups of plug-in grooves 2 are arranged in a circular array on the surface of the steel roller 1.

[0021] In actual use, a plug-in base 3 is set in several groups of plug-in grooves 2 opened on the surface of the steel roller 1, and a rubber strip 4 is fixed on the surface of the plug-in base 3. One end of the rubber strip 4 extends from the plug-in groove 2. The rubber strip 4 is made of a rubber material with a relatively rough surface. When the straw is guided by the steel roller 1, there is a large friction between the rubber strip 4 and the straw, thereby improving the guiding effect of the steel roller 1 on the straw.

[0022] Example 2: On the basis of Example 1, in order to facilitate the replacement of the rubber strip 4 after the rubber strip 4 is worn too seriously, a limit rod mounting groove 5 is provided on the two symmetrical end faces of the plug-in base 3, and a limit groove 6 is provided on the two symmetrical inner walls of the plug-in groove 2. One end of the limit rod 7 is movably inserted in the limit rod mounting groove 5, and the other end of the limit rod 7 is movably inserted in the limit groove 6. The limit rod mounting groove 5 and the limit groove 6 are both circular groove structures, and the limit rod 7 is a circular rod structure. One end of the limit rod 7 extending into the limit rod mounting groove 5 is fixed with a limit spring 8, and the other end of the limit spring 8 is fixed on the inner wall of the limit rod mounting groove 5. The surface of the plug-in groove 2 A button groove 10 is provided on the top, and a button 13 is movably inserted in the button groove 10. The button groove 10 has a circular groove structure, and the button 13 has a circular sheet structure. A connecting rod plug hole 9 is provided between the limit groove 6 and the button groove 10. The connecting rod plug hole 9 has a circular hole structure, and a connecting rod 11 is movably inserted in the connecting rod plug hole 9. The connecting rod 11 has a round rod structure, one end of the connecting rod 11 extends into the button groove 10, and the other end of the connecting rod 11 extends into the limit groove 6. The end of the connecting rod 11 extending into the button groove 10 is fixed on the surface of the button 13, and the end of the connecting rod 11 extending into the limit groove 6 is fixed with a push plate 12, and the other end of the push plate 12 is against the surface of the limit rod 7.

[0023] When the rubber strip 4 needs to be replaced, the button 13 is pressed deep into the button groove 10. The movement of the button 13 pushes the connecting rod 11 to move toward the other end of the connecting rod plug hole 9. The connecting rod 11 pushes the push plate 12 to move in the same direction. The movement of the push plate 12 pushes the limit rod 7 to withdraw from the limit groove 6. After the two groups of limit rods 7 at both ends of the plug-in base 3 withdraw from the limit groove 6 at the same time, the steel drum 1 is rotated to make the group of plug-in bases 3 move to the bottom end of the steel drum 1, so that the plug-in base 3 falls out of the plug-in groove 2 under the action of its own gravity, and the old plug-in is completed. The base 3 and rubber strip 4 are disassembled; then the new plug-in base 3 and rubber strip 4 need to be installed into the plug-in slot 2. During installation, first press the two sets of limit rods 7 on the surface of the new plug-in base 3 completely into the limit rod installation slot 5. The movement of the limit rod 7 compresses the limit spring 8, and then the plug-in base 3 is installed into the plug-in slot 2. When the plug-in base 3 moves to the deep end of the plug-in slot 2, the limit rod installation slot 5 is aligned with the limit slot 6. The limit spring 8 pushes one end of the limit rod 7 into the limit slot 6 under its own elastic action, and the replacement of the plug-in base 3 and the rubber strip 4 is completed.

[0024] In actual use, a plug-in base 3 is set in a plurality of groups of plug-in grooves 2 opened on the surface of the steel drum 1, and a rubber strip 4 is fixed on the surface of the plug-in base 3, and one end of the rubber strip 4 extends out from the plug-in groove 2. The rubber strip 4 is made of a rubber material with a relatively rough surface. When the straw is guided through the steel drum 1, there is a large friction between the rubber strip 4 and the straw, thereby improving the guiding effect of the steel drum 1 on the straw; when the rubber strip 4 needs to be replaced, the button 13 is pressed toward the depth of the button groove 10, and the movement of the button 13 pushes the connecting rod 11 to move toward the other end of the connecting rod plug-in hole 9, and the connecting rod 11 pushes the push plate 12 to move in the same direction, and the movement of the push plate 12 pushes the limit rod 7 to withdraw from the limit groove 6, and the two groups of limit rods 7 at both ends of the plug-in base 3 are simultaneously withdrawn from After exiting the limit slot 6, rotate the steel drum 1 to make the group of plug-in base 3 move to the bottom end of the steel drum 1, so that the plug-in base 3 falls out of the plug-in slot 2 under the action of its own gravity, and the disassembly of the old plug-in base 3 and rubber strip 4 is completed; then the new plug-in base 3 and rubber strip 4 need to be installed into the plug-in slot 2. During installation, first press the two groups of limit rods 7 on the surface of the new plug-in base 3 completely into the limit rod installation slot 5. The movement of the limit rod 7 compresses the limit spring 8, and then the plug-in base 3 is installed into the plug-in slot 2. When the plug-in base 3 moves to the depth of the plug-in slot 2, the limit rod installation slot 5 is aligned with the limit slot 6, and the limit spring 8 pushes one end of the limit rod 7 into the limit slot 6 under the action of its own elasticity, and the replacement of the plug-in base 3 and the rubber strip 4 is completed.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
