Description

Technical Field

[0001] The present invention relates to the technical field of sugarcane harvesters, and in particular to a material shaking mechanism of a sugarcane collecting bucket and a sugarcane harvester. Background Art

[0002] The segmented sugarcane harvester is a widely used type of sugarcane harvester. Currently, sugarcane collection methods primarily include conveyors, net bags, and collection buckets. Compared to conveyors, collection buckets improve the harvester's adaptability to smaller plots, eliminating the need for a transport vehicle and providing more flexible harvesting methods. Compared to net bag collection devices, collection buckets offer larger loading capacities and faster and more flexible unloading, saving the cost of net bags and the labor involved in hanging them.

[0003] However, although the collection buckets carried by some existing sugarcane harvesters have a large volume, they have many problems:

[0004] There are problems with the collection hopper that does not currently have a material shaking function:

[0005] 1. The collection hopper's storage space is not fully utilized, resulting in an increased number of unloading operations for the same harvest volume. This wastes a lot of time during the increased unloading process. Furthermore, the collection device uses a lot of materials, is heavy, and has high manufacturing costs, which results in a poor overall user experience for the harvester.

[0006] 2. The method of relying on the natural falling of sugarcane to be loaded into the collecting bucket can easily cause the fallen sugarcane to accumulate in a cone shape toward the sugarcane outlet of the harvester. When there is still a large amount of free space in the bucket, it will be blocked at the sugarcane outlet, which will seriously affect the fan's impurity removal and even cause the harvester channel to be blocked.

[0007] There are currently problems with the collection hopper with the shaking function:

[0008] 1. The machine needs to be stopped to shake the material. Collecting a full bucket of sugarcane requires multiple stops, which seriously affects the harvesting efficiency.

[0009] 2. The shaking process requires shaking the entire collecting bucket, which requires the collecting bucket to have a higher structural strength and greater shaking power. Summary of the Invention

[0010] In response to the problems existing in the prior art, the present invention provides a material shaking mechanism for a sugarcane collecting bucket, which can achieve material shaking kinetic energy without stopping the machine during the sugarcane harvesting process and avoid the overall shaking of the collecting bucket.

[0011] In order to achieve the above-mentioned object of the invention, the technical solution of the present invention is as follows:

[0012] A material shaking mechanism for a sugarcane collecting bucket comprises a support, a collecting bucket, a first material shaking push plate, a second material shaking push plate and a driving device.

[0013] The upper end of the second material shaking push plate is hinged to the collecting bucket, and the lower end is hinged to the upper end of the first material shaking push plate;

[0014] The lower end of the first material shaking push plate is slidably connected to the side of the collecting bucket;

[0015] The collecting hopper is provided with an opening on its side;

[0016] One end of the driving device is hinged to the support, and the other end passes through the opening and cooperates with the second material shaking push plate to drive the second material shaking push plate to swing relative to the collecting bucket.

[0017] Furthermore, the driving device includes a material shaking cylinder, one end of which is hinged to the support, and the other end of which is hinged to the second material shaking push plate.

[0018] Furthermore, the driving device includes a material shaking swing frame and a material shaking cylinder.

[0019] One end of the shaking material cylinder is hinged to the support, and the other end is hinged to the shaking material swing frame, driving the shaking material swing frame to swing relative to the support;

[0020] The upper end of the shaking material swing frame is hinged to the support, and the lower end is matched with the second shaking material pushing plate.

[0021] Furthermore, the second material shaking push plate is provided with more than two rotating ends hinged to the material shaking oil cylinder.

[0022] Furthermore, the shaking material swing frame is provided with more than two rotating ends hinged to the shaking material cylinder.

[0023] Furthermore, the size of the side opening of the collecting hopper is adapted to the size of the second material shaking push plate.

[0024] Furthermore, the upper end of the second material shaking push plate is hinged to the upper end of the collecting bucket.

[0025] Furthermore, the first material shaking push plate and the second material shaking push plate have the same width and are adapted to the side width of the collecting hopper.

[0026] The present invention also provides a sugarcane harvester, comprising the material shaking mechanism of the sugarcane collecting bucket.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The device provided by the present invention realizes the shaking of materials without stopping the machine through a simple mechanical structure. It has a simple structure and high reliability, eliminating the waste of harvesting time caused by stopping the machine to shake materials.

[0029] 2. The material is shaken by the continuous pushing of the mechanical structure, which avoids the problems of high structural strength requirements and large shaking power requirements caused by the overall shaking of the collection bucket;

[0030] 3. By implementing non-stop material shaking, the sugarcane can be filled into the collecting bucket as much as possible, thus improving the volume utilization of the collecting bucket. This also reduces the number of shutdowns for unloading at the same harvest volume, and reduces the time wasted by frequent unloading.

[0031] 4. During the sugarcane harvesting and collection process, the continuous operation of the shaking mechanism keeps the sugarcane falling naturally at the sugarcane outlet in motion, preventing the sugarcane from accumulating and clogging below the sugarcane outlet, thus eliminating possible blockage of the harvester.

[0032] 5. This device adopts a fully mechanical structure to realize the material shaking function of the collecting bucket. It can achieve the material shaking kinetic energy of the device without stopping the machine at an extremely low cost and without making too many changes to the collecting bucket device itself. It solves the problems of the collecting bucket not being able to be filled and the accumulation of material at the sugarcane outlet of the harvester, improves the collection capacity and harvesting efficiency of the harvester, and reduces the failure rate of the harvester.

DETAILED DESCRIPTION

[0044] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following embodiments are described in conjunction with the accompanying drawings.

[0045] Implementation Figure 2 As shown, a support 2 is fixed to the rear of the sugarcane harvester main body 1. The ends of the rocker arm 3 and connecting rod 4 are hinged to the support 2 and the swing support 6, respectively, forming a quadrilateral structure. The collection bucket 5 is hinged to the swing support 6. The ends of the push-out cylinder 8 are hinged to the support 2 and the rocker arm 3, respectively. When the push-out cylinder 8 is actuated, the swing support 6, collection bucket 6, and bucket tipping cylinder 7 are pushed out as a whole, clearing the harvester's blower to facilitate the bucket tipping and unloading. The ends of the bucket tipping cylinder 7 are hinged to the collection bucket 5 and the swing support 6, respectively. When the bucket tipping cylinder 7 is actuated, the collection bucket 5 is tilted and unloaded. During the sugarcane harvesting and collection process, sugarcane naturally falls from the sugarcane outlet and accumulates in the collection bucket 5. This can easily lead to two problems: sugarcane accumulates and clogs the area below the sugarcane outlet, and the rest of the collection bucket 5 is not fully utilized.

[0046] like Figure 1 、 Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a material shaking mechanism for a sugarcane collecting bucket, which, in addition to a support 2 and a collecting bucket 5, also includes a first material shaking push plate 9, a second material shaking push plate 10 and a driving device, wherein the driving device includes a material shaking swing frame 11 and a material shaking cylinder 12.

[0047] The upper end of the second material shaking push plate 10 is hinged to the collecting bucket 5 , and the second material shaking push plate 10 can swing relative to the collecting bucket 5 , and the lower end is hinged to the upper end of the first material shaking push plate 9 .

[0048] The first material shaking push plate 9 is provided with rollers on both sides of the lower end, and the inner side of the front side of the collecting bucket 5 and the rollers on both sides of the lower end of the first material shaking push plate 9 are provided with slide grooves accordingly, and the rollers at the lower end of the first material shaking push plate 9 can roll up and down in the slide grooves on the inner side of the front side of the collecting bucket 5, so that the lower end of the material shaking push plate 9 is slidingly connected with the front side of the collecting bucket 5. In other embodiments, sliders can also be provided on both sides of the lower end of the first material shaking push plate 9, so that the lower end of the material shaking push plate 9 is slidingly connected with the front side of the collecting bucket 5, and the upper end of the first material shaking push plate 9 and the lower end of the second material shaking push plate 10 are hinged, so that the first material shaking push plate 9 and the second material shaking push plate 10 can swing relative to each other;

[0049] One end of the material shaking cylinder 12 is hinged to the support 2, and the material shaking swing frame 11 is provided with a rotating end on the vertical projection line of the material shaking swing frame 11. The other end of the material shaking cylinder 12 is hinged to the material shaking swing frame 11 through the rotating end, driving the material shaking swing frame 11 to swing relative to the support 2.

[0050] The upper end of the shaking material swing frame 11 is hinged to the support 2, and the shaking material swing frame 11 can swing relative to the support 2. The lower end of the shaking material swing frame 11 is provided with a roller, and the second shaking material push plate 10 and the corresponding parts of the pulley at the lower end of the shaking material swing frame 11 are provided with a chute. When the shaking material swing frame 11 swings relative to the support 2, the lower end of the shaking material swing frame 11 can roll in the chute of the second shaking material push plate 10 through the pulley, driving the second shaking material push plate 10 to swing relative to the collecting bucket 5;

[0051] The collecting hopper 5 is provided with an opening on the front side. When shaking materials, the shaking material swing frame 11 passes through the opening, driving the second shaking material push plate 10 to swing relative to the collecting hopper 5.

[0052] The working principle of this shaking mechanism is as follows:

[0053] like Figure 6 、 Figure 8 As shown, at the beginning of work, the harvester harvests sugarcane, and the sugarcane falls into the collecting bucket 5 through the sugarcane outlet. At this time, the shaking cylinder 12 is pushed out, driving the shaking swing frame 11 to swing away from the harvester (i.e., rearward). During the swinging process, the roller at the lower end of the shaking swing frame 11 rolls into the slide groove on the second shaking push plate 10, driving the second shaking push plate 10 to swing relative to the collecting bucket 5 backward. At this time, the second shaking push plate 10 and the first shaking push plate 9 rotate relative to each other, and drive the roller at the lower end of the first shaking push plate 9 to slide upward in the slide groove on the inner side of the front side of the collecting bucket 5. When the shaking cylinder 12 is extended to the limit position, the shaking swing frame 11, the second shaking push plate 10 and the first shaking push plate 9 all run to the limit position. Figure 7As shown. During the movement, the second material shaking push plate 10 and the first material shaking push plate 9 move backward, pushing the sugarcane to the rear of the collecting bucket 5, thus realizing the material shaking function. Figure 9 shown.

[0054] When the shaking mechanism is reset, the shaking cylinder 12 is retracted, driving the shaking frame 11 to swing toward the harvester. At this time, the roller at the lower end of the shaking frame 11 is still in the chute of the second shaking push plate 10, driving the second shaking push plate 10 to swing toward the harvester. Driven by the second shaking push plate 10, the first shaking push plate 9 slides downward in the chute on the inner side of the front side of the collecting bucket 5. When the cylinder is retracted to the initial state, the roller on the shaking frame 11 is out of the chute on the second shaking push plate 10. At this time, the shaking frame 11, the second shaking push plate 10 and the first shaking push plate 9 are all restored to their initial positions, and the shaking mechanism is completely reset. Figure 10 As shown, after one round of shaking, the blockage of sugarcane accumulation below the sugarcane outlet in the collecting bucket 5 is alleviated, and the space of the collecting bucket 5 is fully utilized. The above-mentioned action is quickly repeated during the harvesting process to achieve the function of shaking without stopping the machine.

[0055] In summary, the device provided by the present invention can achieve non-stop material shaking through a simple mechanical structure. It has a simple structure and high reliability, eliminating the waste of harvesting time caused by stopping to shake the material.

[0056] The material is shaken by the continuous pushing of the mechanical structure, which avoids the problems of high structural strength requirements and large shaking power requirements caused by the overall shaking of the collection bucket;

[0057] By achieving continuous shaking of the sugarcane, the collecting bucket is filled with sugarcane as much as possible, thus improving the volume utilization of the collecting bucket. This also reduces the number of shutdowns for unloading at the same harvest volume, and reduces the time wasted by frequent unloading.

[0058] During the sugarcane harvesting and collection process, the continuous operation of the shaking mechanism keeps the sugarcane falling naturally at the sugarcane outlet in motion, preventing the sugarcane from accumulating and clogging below the sugarcane outlet, thus eliminating possible clogging failures of the harvester.

[0059] This device adopts a fully mechanical structure to realize the material shaking function of the collecting bucket. It can achieve the material shaking kinetic energy of the device without stopping the machine at an extremely low cost and without making too many changes to the collecting bucket device itself. It solves the problems of the collecting bucket not being able to be filled and the accumulation of material at the sugarcane outlet of the harvester, improves the collection capacity and harvesting efficiency of the harvester, and reduces the failure rate of the harvester.

[0060] As a preferred solution, the material shaking swing frame 11 is provided with two rotating ends on the vertical projection line of the material shaking swing frame 11 by adjusting the hinge connection between the material shaking cylinder 12 and the material shaking swing frame 11 at different rotating ends, so as to change the swing amplitude of the material shaking swing frame 11, thereby changing the swing amplitude of the second material shaking push plate 10 relative to the collecting bucket 5 in the material shaking, thereby achieving different material shaking effects.

[0061] As a preferred solution, the size of the front side opening of the collecting hopper 5 is adapted to the size of the second material shaking push plate 10, thereby reducing the area of the front side of the collecting hopper 5 to save costs.

[0062] As a preferred solution, the upper end of the second material shaking push plate 10 is hinged to the upper end of the collecting bucket 5 to achieve a maximum material shaking effect in the height direction of the collecting bucket 5.

[0063] As a preferred solution, the first material shaking push plate 9 and the second material shaking push plate 10 have the same width and are adapted to the width of the front side of the collecting hopper 5 to achieve a maximum material shaking effect in the width direction of the collecting hopper 5.

[0064] In other embodiments, the driving device may also only include the shaking material cylinder 12, and the second shaking material push plate 10 is provided with a rotating end on the vertical projection line of the shaking material cylinder 12. One end of the shaking material cylinder 12 is hinged to the support 2, and the other end is hinged to the second shaking material push plate 10 through the rotating end. The second shaking material push plate 10 and the first shaking material push plate 9 are directly driven by the shaking material cylinder 12 to realize the shaking material function. The shaking material principle is as described above and will not be described. The structure is as follows Figure 5 In order to change the swing amplitude of the second material shaking push plate 10 relative to the collecting hopper 5 during the material shaking and achieve different material shaking effects, the second material shaking push plate 10 can be provided with two or more rotating ends on the vertical projection line of the material shaking cylinder 12 on the second material shaking push plate 10. The above purpose is achieved by adjusting the different rotating ends of the material shaking cylinder 12 and the second material shaking push plate 10 to be hingedly connected.

[0065] Although the present invention has been described in detail above using specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made based on the present invention. Therefore, such modifications or improvements, which do not depart from the spirit of the present invention, are intended to fall within the scope of protection claimed herein.
