Description

Technical Field

[0001] This invention relates to the technical field of sugarcane binding, and more particularly to a sugarcane auxiliary binding device and a sugarcane harvester. Background Technology

[0002] Sugarcane needs to be harvested manually or by machinery such as combine harvesters. However, manual harvesting is extremely inefficient and wastes labor, making it unsuitable for large-scale sugarcane harvesting operations. Therefore, using combine harvesters and other machinery is currently the mainstream method for sugarcane harvesting.

[0003] Specifically, when harvesting sugarcane using a whole-stalk harvester, after the harvester cuts the sugarcane at the roots and leaves, the sugarcane needs to be collected in a concentrated manner to facilitate subsequent bundling and transportation. However, existing sugarcane bundling methods mostly rely on manual labor to tighten the ropes and tie knots, which requires considerable arm strength and is time-consuming and labor-intensive. Existing technologies also include some sugarcane bundling devices. For example, Chinese patent document CN206760090U discloses a bundling mechanism for a sugarcane harvester. This mechanism includes a pressure plate, claws, a threading needle, and a knotter. The pressure plate and claws are used to hold the sugarcane tightly, and then the threading needle and knotter are used to bind the sugarcane. However, because existing sugarcane bundling devices use rigid claws to tighten the sugarcane, the rigid compression of the sugarcane during the tightening process can easily lead to damage, affecting the harvest quality. Summary of the Invention

[0004] To address the above shortcomings, this invention proposes a sugarcane auxiliary binding device and a sugarcane harvester. This sugarcane auxiliary binding device, by adjusting the length of the first tightening belt and driving one end of the second and third tightening belts to move alternately, enables multiple first, second, and third tightening belts to come together and flexibly tighten multiple sugarcane stalks. This not only helps reduce damage to the sugarcane but also allows for the binding of different numbers of sugarcane stalks into bundles.

[0009] Furthermore, the second drive mechanism includes a second motor, the output end of which is connected to a second screw via a belt assembly. The second screw has two second threaded segments with opposite thread directions. Each second threaded segment is connected to a second slider, and each second slider is connected to the corresponding side frame. When the second motor drives the second screw to rotate, the two second sliders move closer to or further away from each other.

[0010] Furthermore, the belt assembly includes a drive pulley connected to the output end of the second motor, a driven pulley at one end of the second screw, and a belt wound between the drive pulley and the driven pulley.

[0011] Furthermore, each of the side frames includes a vertical rod connected to the second slider, and a horizontal plate is vertically connected to the upper end of the vertical rod. The horizontal plate is provided with a plurality of corresponding second moving rods or third moving rods at intervals along its length. The mounting frame includes a guide plate parallel to the horizontal plate, and the guide plate is provided with guide holes through which the corresponding second moving rods or third moving rods can move.

[0012] Furthermore, the mounting bracket includes two opposing side plates, each guide plate has its two ends connected to the side plate by a support rod, a guide rod is provided between the two side plates, and a side extension block is provided at the lower end of the first moving rod, the side extension block is provided with a guide hole through which the guide rod can move.

[0030] See Figures 1 to 4 A sugarcane auxiliary binding device includes: a mounting frame 100, a second movable rod 200, a third movable rod 300, and a second drive mechanism. The mounting frame 100 has two first movable rods 110 arranged opposite each other, with a first tightening strap 111 between the two first movable rods 110. The first tightening strap 111 supports the sugarcane upwards. Each first movable rod 110 is connected to a first drive mechanism that drives it to move horizontally. Multiple second movable rods 200 are movably mounted on the mounting frame 100, and a second tightening strap is provided between each second movable rod 200 and one of the first movable rods 110. 210; Multiple third moving rods 300 are provided, and multiple third moving rods 300 are movably provided on the mounting frame 100. A third tightening band 310 is provided between each third moving rod 300 and another first moving rod 110. Multiple third tightening bands 310 and second tightening bands 210 are staggered along the length direction of the first moving rod 110. A second driving mechanism is provided on the mounting frame 100. The second driving mechanism is used to drive the second moving rod 200 and the third moving rod 300 to move alternately in the horizontal direction, so that the first tightening band 111, the second tightening band 210 and the third tightening band 310 can gather together and tighten multiple sugarcanes.

[0031] In the sugarcane auxiliary binding device with the above structure, during use, the second drive mechanism drives the second moving rod 200 and the third moving rod 300 to separate from each other, allowing multiple sugarcanes to continuously fall towards the first tightening band 111. Then, until the required number of sugarcanes to be bound is reached, the second drive mechanism drives the second moving rod 200 and the third moving rod 300 to move closer to each other. Finally, the second moving rod 200 and the third moving rod 300 respectively drive multiple second tightening bands 210 and third tightening bands 310 to interweave, so that the first tightening band 111, the second tightening band 210 and the third tightening band 310 can gather together and tighten multiple sugarcanes. By simulating the way a human hand tightens sugarcane with ropes, it not only reduces the damage to sugarcane tightening caused by the existing rigid claw method, but also can accommodate different numbers of sugarcane and tighten them into bundles, which is beneficial for subsequent binding of sugarcane using threading needles and knotters. The first drive mechanism can change the distance between the two first moving rods 110, which facilitates the first tightening band 111, the second tightening band 210, and the third tightening band 310 to jointly hold the sugarcane, thereby better accommodating different numbers of sugarcane. Furthermore, the multiple first tightening bands 111, the second tightening band 210, and the third tightening band 310 tighten along the length perpendicular to the sugarcane, which helps improve the stability of the bundle formed by multiple sugarcane stalks, thus facilitating the subsequent binding of the sugarcane.

[0032] See Figures 1 to 3 Furthermore, the first driving mechanism includes a first motor 120, the output end of which is connected to a first screw 121. The first screw 121 has two first threaded sections with opposite thread directions. Each first threaded section is connected to a first slider 122, and each first slider 122 is connected to a corresponding first moving rod 110. When the first motor 120 drives the first screw 121 to rotate, the two first sliders 122 move closer to or further away from each other. Specifically, in use, the first motor 120 drives the first screw 121 to rotate, causing the two first sliders 122 to move closer to or further away from each other along the length direction of the first screw 121 under the action of opposite threads. This causes the two first moving rods 110 to move relative to each other to change their distance, thereby changing the length of sugarcane that the first tightening band 111 can support, thus better matching different quantities of sugarcane to be tightened into bundles. The method of using the first motor 120 to drive the first screw 121 not only reduces the number of driving devices, but also helps to improve the accuracy of the movement of the first moving rod 110 relative to the mounting frame 100, and helps to better control the stroke of the first moving rod 110 so as to control the length of the first tightening belt 111 that can abut against the sugarcane.

[0033] See Figures 1 to 3Furthermore, the mounting frame 100 is movably provided with two side frames 130, a plurality of second moving rods 200 are connected to one side frame 130, a plurality of third moving rods 300 are connected to the other side frame 130, and a second drive mechanism is connected to the two side frames 130. The second drive mechanism is used to drive the two side frames 130 to move closer or further away from each other, thereby driving the movement of the two side frames 130 through the second drive mechanism, so as to indirectly drive the plurality of second moving rods 200 and third moving rods 300 to move synchronously and alternately, which is beneficial to drive the plurality of second tightening belts 210 and third tightening belts 310 to alternately and alternately to tighten multiple sugarcanes.

[0034] See Figures 1 to 3 Furthermore, the second drive mechanism includes a second motor 400. The output end of the second motor 400 is connected to a second screw 410 via a belt assembly. The second screw 410 has two second threaded sections with opposite thread directions. Each second threaded section is connected to a second slider 420, and each second slider 420 is connected to a corresponding side frame 130. When the second motor 400 drives the second screw 410 to rotate, the two second sliders 420 move closer to or further away from each other. Specifically, in use, the second motor 400 drives the second screw 410 to rotate, causing the two second sliders 420 to move closer to or further away from each other along the length of the second screw 410 under the action of opposite threads. This causes the second moving rod 200 and the third moving rod 300 to move closer to or further away from each other, which in turn causes the second tightening belt 210 and the third tightening belt 310 to tightly hold multiple sugarcane stalks together, which is beneficial for achieving the effect of bundling multiple sugarcane stalks together. The method of using a second motor 400 to drive the first screw 121 not only reduces the number of driving devices but also improves the accuracy of the movement of the second moving rod 200 and the third moving rod 300, and facilitates better control of their travel. In some embodiments, the second driving mechanism includes a motor, the output end of which is connected to a gear. Racks mesh between the upper and lower ends of the gear, and the two racks are respectively connected to corresponding side frames 130. When the motor drives the gear to rotate forward and backward, one end of each rack moves away from or towards the other, thereby moving the two side frames 130.

[0035] See Figures 1 to 3 Furthermore, the belt assembly includes a drive pulley 401 connected to the output end of the second motor 400, a driven pulley 411 at one end of the second screw 410, and a belt 412 wound between the drive pulley 401 and the driven pulley 411. This facilitates changing the mounting position of the second motor 400, making the structural layout of the second drive mechanism more compact, and also allows for better transmission of the output torque of the second motor 400 using the belt 412. It is understood that the output end of the second motor 400 can also transmit torque via sprockets and chains.

[0036] See Figures 1 to 3 Furthermore, each side frame 130 includes a vertical rod 131 connected to the second slider 420. A horizontal plate 132 is vertically connected to the upper end of the vertical rod 131. Multiple corresponding second moving rods 200 or third moving rods 300 are spaced apart along the length of the horizontal plate 132. The mounting frame 100 includes a guide plate 140 parallel to the horizontal plate 132. The guide plate 140 has guide holes through which the corresponding second moving rods 200 or third moving rods 300 can move. Specifically, during the movement of the side frame 130 driven by the second slider 420, the second moving rods 200 or third moving rods 300 pass through the corresponding guide holes. The guide plate 140 then guides and limits the movement of the second moving rods 200 and third moving rods 300, facilitating translational movement of the second moving rods 200 and third moving rods 300 relative to the guide plate 140. The upright 131 and the horizontal plate 132 are fixed together by welding, which helps to improve the structural strength of the side frame 130 and also helps the side frame 130 to drive multiple second moving rods 200 or third moving rods 300 to move synchronously.

[0037] See Figures 1 to 3 Furthermore, the mounting frame 100 includes two opposing side plates 141. Each guide plate 140 is connected to its two ends by a support rod 142. A guide rod 150 is provided between the two side plates 141. A side extension block 112 is provided at the lower end of the first moving rod 110. The side extension block 112 has a guide hole through which the guide rod 150 can move. Specifically, the cooperation between the guide rod 150 and the guide hole allows the side extension block 112 to translate along the length of the guide rod 150, which helps to regulate the translational movement of the two first moving rods 110 relative to the mounting frame 100.

[0038] See Figure 4 Furthermore, a guide wheel 113 is rotatably mounted on the outer periphery of the first moving rod 110. The first tightening belt 111, the second tightening belt 210, and the third tightening belt 310 are an integral structure, with the first tightening belt 111 wrapped around the outer periphery of the two guide wheels 113. Specifically, the first tightening belt 111, the second tightening belt 210, and the third tightening belt 310 are the same rope. The middle of the rope is guided and steered by the two guide wheels 113, and the two ends of the rope move alternately through the second moving rod 200 and the third moving rod 300, respectively, which facilitates the tightening of the rope to hold multiple sugarcane stalks together. It can be understood that the first moving rod 110 is a round rod, and the guide wheel 113 is movably sleeved on the outer periphery of the round rod, allowing the guide wheel 113 to rotate relative to the round rod.

[0039] Furthermore, the first tightening band 111, the second tightening band 210, and the third tightening band 310 are elastic bands, and a friction texture layer is provided on the surface of the elastic band facing the sugarcane. Specifically, the elastic band can be made of existing rubber material, which is beneficial for matching different movement strokes through elastic band stretching deformation, thereby facilitating the elastic band to gather multiple sugarcane stalks together. The friction texture layer helps increase the frictional force in contact with the outer peripheral wall of the sugarcane, thereby preventing excessive slippage of the sugarcane during the binding process and facilitating better subsequent binding of multiple sugarcane stalks.

[0040] The present invention also discloses a sugarcane harvester, which adopts a sugarcane auxiliary binding device as described in any of the above technical solutions. By adjusting the length of the first tightening belt 111 and driving one end of the second tightening belt 210 and the third tightening belt 310 to move alternately, multiple first tightening belts 111, second tightening belts 210 and third tightening belts 310 can be gathered together and flexibly tighten multiple sugarcanes. This not only helps to reduce damage to the sugarcane, but also enables different numbers of sugarcanes to be tightly bound together.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
