Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology. Specifically, this invention relates to a structure and method for suppressing material rebound on the wall surface of an opposed compression square baler. Background Technology

[0002] Balers can be divided into external winding round bale balers and internal winding round bale balers according to the different ways they form round bales. The bales produced by external winding round bale balers have the characteristics of being loose inside and tight outside, while the bales produced by internal winding round bale balers have the characteristics of being tight inside and loose outside. Because the internal and external densities of the round bales produced by the two types are quite different and uneven, the overall density is not high. Therefore, it is not conducive to the later silage operation of round bales, and it also affects the transportation cost of round bales.

[0003] In existing compression chamber structures, excessive friction between the inner wall and the material leads to excessive energy consumption. Additionally, due to the material's flow and creep characteristics, it exhibits a certain degree of rebound, resulting in insufficient compression density and loose material bundles. Summary of the Invention

[0004] This invention provides a wall structure and method for suppressing material rebound in a counter-compression square bale machine. The design of the arched wall surface suppresses the rebound of the compressed square bale material, thereby improving the final forming density of the square bale material.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a wall structure and method for suppressing material rebound in a counter-compression type square bundler, comprising a left hydraulic cylinder, a left pressure plate, a left smooth wall, a left arched array wall, and a base plate. The output end of the left hydraulic cylinder is fixedly connected to one side of the left pressure plate, the bottom of the left pressure plate is slidably connected to the top of the left smooth wall, one side of the left smooth wall is fixedly connected to the left arched array wall, and the other side of the left arched array wall is fixedly connected to one side of the base plate.

[0006] It also includes a right-side hydraulic cylinder, a right-side pressure plate, a right-side smooth wall, and a right-side arched array wall. The output end of the right-side hydraulic cylinder is fixedly connected to one side of the right-side pressure plate. The bottom of the right-side pressure plate is slidably connected to the top of the right-side smooth wall. One side of the right-side smooth wall is fixedly connected to the right-side arched array wall. The other side of the right-side arched array wall is fixedly connected to the other side of the base plate.

[0007] Preferably, both the left and right arched array walls adopt an arched array structure.

[0008] Preferably, the axes of the left and right arched array walls form a 45° angle with the plane of the base plate.

[0009] Preferably, both the left and right arched array walls are made of elastic materials.

[0010] A method for suppressing material rebound in a counter-compression square baler specifically includes the following steps:

[0011] Step S1, material enters;

[0012] Step S2: Activate the left and right hydraulic cylinders to compress the material;

[0013] Step S3: Compress the material until it reaches the size required by the square bundling machine, then end the compression process.

[0014] Step S4: The left and right hydraulic cylinders maintain pressure and allow for springback allowance;

[0015] In step S5, the left and right hydraulic cylinders return to their original positions, and the left and right arched array walls suppress the rebound.

[0016] The beneficial effects of adopting the above technical solutions are:

[0017] One key feature is the use of an arched wall design, which suppresses the springback of the compressed bales, thereby increasing the final forming density of the bales.

[0018] Secondly, a certain gap is left between each arch, which ensures the suppression of rebound while maintaining the flowability of the material and ensuring that the compression process does not generate a large amount of energy consumption, thereby ensuring production efficiency.

[0023] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and to facilitate its implementation.

[0024] like Figures 1 to 2 As shown, the present invention is a wall structure and method for suppressing material rebound in a counter-compression square bale machine. The key feature is the use of an arched wall design to suppress the rebound of the compressed square bale material, thereby improving the final forming density of the square bale material.

[0025] Specifically, such as Figures 1 to 2 As shown, it includes a left hydraulic cylinder 1, a left pressure plate 2, a left smooth wall 3, a left arched array wall 4, and a base plate 5. The output end of the left hydraulic cylinder 1 is fixedly connected to one side of the left pressure plate 2. The bottom of the left pressure plate 2 is slidably connected to the top of the left smooth wall 3. One side of the left smooth wall 3 is fixedly connected to the left arched array wall 4. The other side of the left arched array wall 4 is fixedly connected to one side of the base plate 5.

[0026] It also includes a right hydraulic cylinder 6, a right pressure plate 7, a right smooth wall 8, and a right arched array wall 9. The output end of the right hydraulic cylinder 6 is fixedly connected to one side of the right pressure plate 7. The bottom of the right pressure plate 7 is slidably connected to the top of the right smooth wall 8. One side of the right smooth wall 8 is fixedly connected to the right arched array wall 9. The other side of the right arched array wall 9 is fixedly connected to the other side of the base plate 5.

[0027] Both the left arched array wall 4 and the right arched array wall 9 adopt an arched array structure.

[0028] The axes of the left arched array wall 4 and the right arched array wall 9 both form a 45° angle with the plane of the base plate 5.

[0029] Both the left arched array wall 4 and the right arched array wall 9 are made of elastic material.

[0030] A method for suppressing material rebound in a counter-compression square baler specifically includes the following steps:

[0031] Step S1, material enters;

[0032] Step S2: Start the left hydraulic cylinder 1 and the right hydraulic cylinder 6 to squeeze the material;

[0033] Step S3: Compress the material until it reaches the size required by the square bundling machine, then end the compression process.

[0034] Step S4: The left hydraulic cylinder 1 and the right hydraulic cylinder 6 maintain pressure and allow for springback.

[0035] In step S5, the left hydraulic cylinder 1 and the right hydraulic cylinder 6 return to their original positions, and the left arched array wall 4 and the right arched array wall 9 suppress the rebound.

[0036] The specific working method is described below using specific embodiments: Example 1

[0037] When the material enters between the left pressure plate 2 and the right pressure plate 7, the left hydraulic cylinder 1 and the right hydraulic cylinder 6 are activated. Driven by the left hydraulic cylinder 1 and the right hydraulic cylinder 6, the left pressure plate 2 exerts a downward pressure perpendicular to the left smooth wall 3 on the material, and the right pressure plate 7 exerts a downward pressure perpendicular to the right smooth wall 8 on the material. Driven by the pressure, the material is squeezed on the left smooth wall 3 and the right smooth wall 8 and moves downward. Example 2

[0038] Based on Example 1, when the material is compressed onto the left arched array wall 4 and the right arched array wall 9 by the left pressure plate 2 and the right pressure plate 7 respectively, since there is a certain gap between each arch of the left arched array wall 4 and the right arched array wall 9, the squeezing action of the left pressure plate 2 and the right pressure plate 7 will not have a significant interference effect. The material continues to be compressed downwards for a certain distance until the size required by the square bundling machine is reached, and the compression process ends. Example 3

[0039] Based on Example 2, after the compression process is completed, the left hydraulic cylinder 1 and the right hydraulic cylinder 6 maintain pressure, and the left pressure plate 2 and the right pressure plate 7 maintain the squeezing effect on the bundled material, which leaves a certain springback margin; the left hydraulic cylinder 1 and the right hydraulic cylinder 6 return, and the material springs back under the effect of internal stress relaxation. The left arched array wall 4 and the right arched array wall 9 suppress the springback phenomenon and ensure the subsequent molding density.

[0040] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other situations without modification, are all within the protection scope of the present invention.
