Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of agricultural machinery straw bundling, in particular to a bundling test bench. BACKGROUND

[0002] The knotter is a core component of the square bale baler, is an automatic device for tying crop straw or pasture with a rope knot, and has been widely used in square balers worldwide. The debugging of the knotter assembled to the knotting system with the baling needle and the tensioning system is a complex and critical link that affects the baling formation. After debugging the knotting system, the baling needle and the tensioning system, it is difficult to detect whether the knotting is successful and the baling formation is reliable. The previous method is to assemble the above three components on the baler and debug them, and then perform pasture picking and baling to test the baling and knotting.

[0003] Due to the interference and obstruction of the baling machine systems, the debugging of the baling system, the baling needle device and the tensioning system is difficult, the debugging period is long, and the debugging efficiency is low. The above factors seriously affect the production efficiency of the baling machine. Therefore, a debugging test bench specially used for the debugging of the three key systems of the knotting system, the baling needle and the tensioning system is needed to detect the running stability, reliability and fatigue strength of each system. The three systems are quickly debugged to qualified line through the test bench to improve the assembly and debugging efficiency of the baling machine. The existing technology has solved the continuous knotting simulation test of a single knotter and can perform single rope simulation baling, such as the scheme provided in patent No. CN106768918A knotter knotting rate detection and fatigue test test bench. However, the scheme is for knotting knotting rate detection and fatigue test of a single knotter, and the baling needle structure is specially used for the test device. The test device cannot debug and detect the knotting system module and the baling needle module composed of multiple rows of baling needles on the baler. Therefore, it is not suitable for debugging and detecting the baling machine module. UTILITY MODEL CONTENTS

[0032] The embodiments of the present application will be described in detail below with reference to the accompanying drawings, but the present application can be implemented in various different ways as defined and covered below. Figures 1-8 The present application is further described in detail.

[0033] The embodiments of the present application disclose a needling test bench.

[0034] Referring to Figure 1 , the needling test bench comprises a test frame 1, a needling channel for the simulated bale 3 to pass through is formed on the test frame 1, a needling needle module 7 for needling the simulated bale 3 is arranged in the needling channel, the test frame 1 is provided with a knotting system module 4 cooperating with the needling needle module 7 to knot the needling rope; the test frame 1 is provided with a power system 6 for providing power for the movement of the knotting system and the needling needle module 7, and the needling needle module 7 and the knotting system module 4 are detachably connected with the test frame 1. By arranging the needling channel, the needling needle module 7, the knotting system module 4 and the power system 6 on the test frame 1, the test bench can accurately position and needling operate the simulated bale 3 in the limited channel, and the detachable connection design facilitates the replacement and debugging of the needling needle module 7 and the knotting system module 4, and the power system 6 provides stable operating power for them, so as to realize the independent testing and debugging of the core modules of the large square bale needling machine, and ensure the coordination and reliability of the operation of each module.

[0035] The test rack 1 is detachably provided with a tensioning mechanism module 9 for tensioning the binding rope, and the tensioning mechanism module 9 and the knotting system module 4 are arranged on different sides of the binding needle module 7. By detachably mounting the tensioning mechanism module 9 on the test rack 1, and arranging the tensioning mechanism module 9 and the knotting system module 4 on different sides of the binding needle module 7 respectively, independent adjustment and control of the tension of the binding rope is realized, ensuring that the binding rope always maintains an appropriate tensioning state during the binding process, thereby improving the firmness and reliability of the binding knotting of the binding rope. Meanwhile, the detachable design facilitates quick replacement and debugging of the modules, thereby improving the flexibility and adaptability of the test bench.

[0036] Referring to Figure 2 and Figure 3 , the test rack 1 is provided with a limiting block 11 in the binding channel, which is used to position the binding position of the simulated straw bale 3. By providing the limiting block 11 in the binding channel of the test rack 1, the binding position of the simulated straw bale 3 is accurately positioned, ensuring that the straw bale remains stable and is in the best position during the binding process, thereby improving the binding accuracy and knotting reliability of the binding rope. Meanwhile, it is convenient for the debugging personnel to unify the position parameters of the straw bale, avoiding running faults and test errors caused by the deviation of the straw bale, and further improving the debugging efficiency of the test bench and the accuracy of the test results.

[0037] Specifically, referring to Figure 8 The limiting block 11 includes an upper limiting plate 111 and a lower limiting plate 112, and a cavity for being sleeved on the test rack is formed between the upper limiting plate 111 and the lower limiting plate 112. A fixing bolt 113 is threadedly connected to the lower limiting plate 112, and the fixing bolt 113 is used to lock the lower limiting plate 112 to the test rack. By firmly locking the fixing bolt 113 on the lower limiting plate 112 to the test rack 1, stable installation and accurate positioning of the limiting block 11 on the test rack 1 are realized, ensuring that the limiting block 11 will not be displaced during the binding process of the straw bale, thereby providing reliable fixation and position guidance for the simulated straw bale 3.

[0038] Referring to Figure 4 , the power system 6 includes a rotary drive source and a driving sprocket 65 connected to the output shaft of the rotary drive source. A driven sprocket is arranged on the knotting system spindle, and a chain 5 is arranged in tension on the driving sprocket 65 and the driven sprocket. The rotary drive source in the power system 6 drives the driving sprocket 65 to rotate, and the driving sprocket 65 and the driven sprocket are connected through the tensioned chain 5, so that the rotary power is transmitted to the knotting system spindle, realizing efficient transmission and synchronous driving of the power, ensuring that the knotting system moves coordinately and uniformly during operation, thereby improving the knotting efficiency and reliability.

[0039] The manual adjusting rod 8 is connected to the driving sprocket 65 at the shaft center position to manually adjust the knotting system, and the manual adjusting rod 8 is perpendicular to the shaft center of the driving sprocket 65. By connecting the manual adjusting rod 8 to the shaft center of the driving sprocket 65 and making the manual adjusting rod 8 perpendicular to the shaft center of the driving sprocket 65, the debugging personnel can manually drive the driving sprocket 65 by rotating the manual adjusting rod 8, thereby driving the knotting system to run at a low speed for adjustment. In specific use, the debugging personnel can accurately control the running speed and position of the knotting system by manually rotating the adjusting rod 81, which is used to observe and adjust the relative position and running state of each component, quickly troubleshoot knotting faults and optimize system parameters, thereby ensuring the normal operation and coordination of the knotting system in the preliminary debugging stage. Referring to Figure 6 In a specific embodiment, the manual adjusting rod 8 includes an adjusting rod 81 and a rod head.

[0040] The power frame 63 for supporting the rotary driving source is arranged on the test rack 1, the transmission shaft 64 is rotatably connected to the power frame 63, one end of the transmission shaft 64 is connected to the rotary driving source, and the other end is connected to the driving sprocket 65. By arranging the power frame 63 for supporting the rotary driving source on the test rack 1, and rotatably connecting the transmission shaft 64 to the power frame 63, one end of the transmission shaft 64 is connected to the rotary driving source, and the other end is connected to the driving sprocket 65, the stable transmission and effective support of the output power of the rotary driving source are realized. In specific use, the rotary driving source is connected to the power frame 63 through the power connection flange 62 to maintain stability on the rack. When driving, the output shaft of the rotary driving source transmits power to the driving sprocket 65 through the transmission shaft 64, thereby driving the chain 5 and the knotting system to run synchronously. Specifically, the rotary power source is a hydraulic motor or an electric motor 61.

[0041] Referring to Figure 5 The simulation bale 3 includes a frame and an elastic layer wrapped on the frame. By designing the simulation bale 3 to be composed of a frame and an elastic layer wrapped on the frame, it not only has sufficient structural strength to maintain the shape, but also simulates the flexibility and resilience characteristics of the actual bale through the elastic layer. In specific arrangement, the frame is made of a cuboid profile to provide a stable support structure, and the elastic layer is wrapped outside the frame with a material having high hardness and resilience. Through this design, the simulation bale 3 can be repeatedly used to realize continuous baling on the test bench, thereby reducing the cost of test consumables. Specifically, the simulation bale 3 includes a simulation bale skeleton 71 and a simulation bale wrapping sponge 72.

[0042] Two rope boxes 2 for accommodating the binding rope are arranged on the test rack 1, and the two rope boxes 2 are located on different sides of the binding channel, the binding rope in one rope box 2 extends into the binding needle module 7, and the binding rope in the other rope box 2 extends into the tensioning mechanism module 9. By arranging two rope boxes 2 for accommodating the binding rope on the test rack 1, and arranging them on the two sides of the binding channel respectively, the binding rope in one rope box 2 is connected with the binding needle module 7 for completing the threading operation of the binding rope, and the binding rope in the other rope box 2 is connected with the tensioning mechanism module 9 for providing and adjusting the tension of the binding rope. In specific use, the operator first guides the binding ropes in the two rope boxes 2 to the corresponding modules respectively, ensures that the upper and lower binding ropes are tensioned according to the requirements, and then realizes winding through the binding needle module 7, and finally completes the knotting operation by the knotting system. The design ensures the independent supply and tension control of the upper and lower binding ropes, thereby improving the reliability of knotting and the binding effect, and facilitating the replacement and debugging of the binding rope.

[0043] Reference Figure 7 In order to avoid the movement of the simulated hay bale 3 during binding, the test rack 1 is provided with a pile press 10, and the pile press 10 comprises a pressing rod and a height adjusting plate connected to the pressing rod. By arranging the pile press 10 on the test rack 1, wherein the pile press 10 is composed of a pressing rod and a height adjusting plate connected to the pressing rod, the simulated hay bale 3 is pressed during the binding process to prevent it from moving. In specific use, the debugging personnel adjusts the position of the height adjusting plate according to the size and height of the simulated hay bale 3, so that it fits the surface of the hay bale, and then applies appropriate pressure downward through the pressing rod to fix the hay bale in the binding channel, so as to ensure that the hay bale remains stationary during the binding process.
