Description

Technical Field

[0001] The invention relates to the technical field of agricultural harvester equipment, in particular to a material shaking mechanism and a material shaking type flexible sugarcane collecting bucket. 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] The collection and conveying devices of a segmented sugarcane harvester mainly include a conveyor, a net bag, and a collection bucket. The collection bucket can improve the operating capacity of small and medium-sized harvesters on small plots. However, although the collection buckets of 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 hopper, which requires the collection hopper to have a higher structural strength and greater shaking power. Summary of the Invention

[0010] In response to the above-mentioned existing defects, the purpose of the present invention is to provide a material shaking mechanism and a material shaking type flexible sugarcane collecting bucket, so that the harvester with a bucket can shake the material without stopping, thereby solving the problem that the space utilization rate of the harvester collection bucket is low and the sugarcane outlet is easily blocked by material accumulation.

[0011] The technical solutions of the present invention are as follows:

[0012] A material shaking mechanism includes a support, a material shaking swing frame, a material shaking cylinder, and a material shaking push plate. The support includes symmetrically arranged L-shaped brackets; the upper parts of the two L-shaped brackets are connected by an upper crossbeam, and the angle between the two L-shaped brackets is connected by a lower crossbeam. A space for accommodating a collection bucket is formed between the two L-shaped brackets.

[0013] The upper part of the shaking material swing frame is hinged to the upper crossbeam, and a pulley is provided at the lower part of the shaking material swing frame; one end of the shaking material cylinder is hinged to the lower crossbeam, and the other end of the shaking material cylinder is hinged to the middle part of the shaking material swing frame; the upper end of the shaking material push plate is hinged to the upper end of one side of the collecting bucket, and the outer side of the shaking material push plate is in sliding contact with the pulley; the shaking material swing frame drives the shaking material push plate to perform reciprocating swinging motion through the extension and contraction of the shaking material cylinder.

[0014] Specifically, at least two hinge holes are provided in the middle of the shaking material swing frame, and the at least two hinge holes are evenly distributed in the vertical direction.

[0015] Specifically, both ends of the upper crossbeam are hinged to the tops of the two L-shaped brackets through connecting plates.

[0016] Specifically, an arc-shaped bending portion is provided at the lower end of the material shaking push plate, and the bending direction of the arc-shaped bending portion is toward the side in contact with the pulley of the material shaking swing frame.

[0017] Specifically, two vertical reinforcing ribs are provided on the shaking material push plate on the side in contact with the pulley of the shaking material swing frame, and the vertical reinforcing ribs form a wheel groove to limit the pulley laterally.

[0018] The present invention also provides a shaking type flexible sugarcane collecting bucket, which adopts the above-mentioned shaking mechanism and includes a collecting bucket. A side opening is provided on one side of the collecting bucket, and the lower end of the shaking push plate is located in the middle of the side opening. The upper part of the shaking push plate is hinged to the collecting bucket above the side opening; the side opening is provided with a flexible net bag, and the flexible net bag is an elastic material piece that can be arbitrarily expanded and contracted within a certain range. The flexible net bag is expanded and contracted by the reciprocating swing of the shaking push plate, driving the movement of sugarcane in the collecting bucket.

[0019] Specifically, a feed port is provided above the collecting bucket, and rocking arms and bucket cylinders are hinged at the corners above the collecting bucket on both sides of the two L-shaped brackets; the end of the bucket cylinder is hinged to the middle of the rocking arm; the lower ends of the two L-shaped brackets are respectively hinged with a first connecting rod, and the middle of the lower parts of the two L-shaped brackets are respectively hinged with a second connecting rod, and the ends of the first connecting rod and the second connecting rod are respectively hinged to the middle of the rocking arm and the end of the rocking arm; the upper ends of the two L-shaped brackets are hinged with a pushing cylinder, and the other end of the pushing cylinder is hinged to the middle of the second connecting rod.

[0020] Beneficial effects of the present invention:

[0021] 1. This device adopts a relatively simple mechanical structure to achieve non-stop material shaking. Its simple structure and high reliability eliminate the waste of harvesting time caused by stopping to shake the material, thus improving the operating efficiency of the sugarcane harvester;

[0022] 2. By implementing continuous unloading and shaking of sugarcane, the collecting hopper is filled as full as possible, thus improving the volume utilization of the collecting hopper. This also reduces the number of unloading stops for the same harvest volume and reduces the time wasted due to frequent unloading.

[0023] 3. By implementing continuous material shaking, the sugarcane falling naturally at the sugarcane outlet is continuously pushed by the material shaking mechanism and moves toward the rear of the hopper, preventing sugarcane from accumulating and clogging below the sugarcane outlet, reducing the harvester's failure rate and improving operating performance.

[0024] 4. This device adopts a flexible collection hopper form, which can achieve the kinetic energy of material shaking without stopping the device at a very low cost and without making too many changes to the hopper device itself, thus reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

In the description of the embodiments, it should be understood that the terms indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the embodiments and simplify the description. They do not indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0034] Example 1

[0035] like Figure 1-2 The material shaking mechanism shown in the figure includes a support 1, a material shaking swing frame 2, a material shaking cylinder 3 and a material shaking push plate 4. The support 1 includes symmetrically arranged L-shaped brackets 101; the two L-shaped brackets 101 are connected by an upper crossbeam 102 at the top, and the two L-shaped brackets 101 are connected by a lower crossbeam 103 at the angle between them, forming a space for accommodating a collection hopper between the two L-shaped brackets 101;

[0036] The top of the shaking material swing frame 2 is hinged to the upper crossbeam 102, and a pulley 202 is provided at the bottom of the shaking material swing frame 2; one end of the shaking material cylinder 3 is hinged to the lower crossbeam 103, and the other end of the shaking material cylinder 3 is hinged to the middle part of the shaking material swing frame 2; the upper end of the shaking material push plate 4 is hinged to the upper end of one side of the collecting bucket 5, and the outer side of the shaking material push plate 4 is in sliding contact with the pulley 202; the shaking material swing frame 2 drives the shaking material push plate 4 to perform reciprocating swinging motion through the extension and retraction of the shaking material cylinder 3.

[0037] The working principle of this embodiment is as follows:

[0038] like Figure 3 As shown, when the harvester is harvesting sugarcane, the sugarcane falls from above into the collection hopper 5. At this point, the shaking cylinder 3 is pushed out, driving the shaking frame 2 to swing toward the inside of the collection hopper 5. During the swinging process, the roller at the lower end of the shaking frame 2 contacts a surface of the shaking push plate 4 202 facing the outside of the collection hopper 5 and rolls relative to it, driving the shaking push plate 4 to swing toward the inside of the collection hopper 5. When the shaking cylinder 3 is extended to its maximum stroke, the pushing action ends, and the shaking frame 2 and the shaking push plate 4 reach their maximum angle. This process can push the sugarcane accumulated under the sugarcane outlet toward the rear of the collection hopper 5, achieving the purpose of shaking. When the shaking cylinder 3 is retracted, the shaking frame 2 is reset under the pulling action of the shaking cylinder 3, and the shaking push plate 4 is reset toward the harvester due to gravity until the shaking cylinder 3 is fully retracted. Repeating these actions rapidly during the harvesting process achieves the non-stop shaking function. Therefore, during the process of loading the storage hopper 5, there is no need to stop the machine to shake the material, which improves the working efficiency and increases the space utilization rate of the harvester collection bucket. The shaking of the material fills the collection bucket with sugarcane, and the sugarcane outlet is not easily blocked by material accumulation, thereby achieving the purpose of the invention.

[0039] Example 2

[0040] like Figure 1-2 The material shaking mechanism shown in the figure includes a support 1, a material shaking swing frame 2, a material shaking cylinder 3 and a material shaking push plate 4. The support 1 includes symmetrically arranged L-shaped brackets 101; the two L-shaped brackets 101 are connected by an upper crossbeam 102 at the top, and the two L-shaped brackets 101 are connected by a lower crossbeam 103 at the angle between them, forming a space for accommodating a collection hopper between the two L-shaped brackets 101;

[0041] The top of the shaking material swing frame 2 is hinged to the upper crossbeam 102, and a pulley 202 is provided at the bottom of the shaking material swing frame 2; one end of the shaking material cylinder 3 is hinged to the lower crossbeam 103, and the other end of the shaking material cylinder 3 is hinged to the middle part of the shaking material swing frame 2; the upper end of the shaking material push plate 4 is hinged to the upper end of one side of the collecting bucket 5, and the outer side of the shaking material push plate 4 is in sliding contact with the pulley 202; the shaking material swing frame 2 drives the shaking material push plate 4 to perform reciprocating swinging motion through the extension and retraction of the shaking material cylinder 3.

[0042] In this embodiment, at least two hinge holes 201 are provided in the middle of the shaking material swing frame 2, and at least two hinge holes 201 are evenly distributed along the vertical direction. Different hinge holes 201 can be installed in different shaking material cylinders 3 to adjust the swing angle of the shaking material swing frame 2 with the cylinder.

[0043] In this embodiment, the two ends of the upper crossbeam 102 are hinged to the upper parts of the two L-shaped brackets 101 through the connecting plates 104. The relative positions of the shaking material swing frame 2 and the shaking material push plate 4 can be adjusted by the hinged connection of the upper crossbeam 102.

[0044] In this embodiment, the lower end of the shaking material push plate 4 is provided with an arc-shaped bent portion 401, and the bending direction of the arc-shaped bent portion 401 is toward the side in contact with the pulley 202 of the shaking material swing frame 2. The arc-shaped bent portion 401 in contact with the sugarcane is conducive to avoiding damage to the sugarcane.

[0045] In this embodiment, at least two vertical reinforcing ribs 402 are provided on the side of the material shaking push plate 4 that contacts the pulley 202 of the material shaking swing frame 2. The two vertical reinforcing ribs 402 form a wheel groove to limit the lateral position of the pulley 202. The limiting structure prevents lateral displacement between the pulley 202 and the material shaking push plate 4 during pushing, which would cause uneven force on the material shaking push plate 4.

[0046] The working principle of this embodiment is the same as that of embodiment 1.

[0047] Example 3

[0048] This embodiment further provides a shaking type sugarcane flexible collecting bucket based on embodiment 1. Figure 5 、 Figure 6 、 Figure 7 As shown, it includes a collecting bucket 5, and a side opening 501 is provided on one side of the collecting bucket 5. The lower end of the material shaking push plate 4 is located in the middle of the side opening 501, and the upper part of the material shaking push plate 4 is hinged to the collecting bucket 5 above the side opening 501; the side opening 501 is provided with a flexible net bag 6, and the flexible net bag 6 is an elastic material piece that can be arbitrarily expanded and contracted within a certain range. The material shaking push plate 4 swings back and forth to push the flexible net bag 6 to drive the sugarcane in the collecting bucket 5 to move.

[0049] The flexible collecting bucket is composed of a collecting bucket 5 and a flexible net bag 6. The flexible net bag 6 has various implementation forms, such as Figure 6 As shown, a net bag, mesh 601, canvas 602, or other flexible materials that meet the requirements can be used. The collecting hopper 5 is the main structure and serves as a load-bearing device. The flexible net bag 6 mainly shields the side of the collecting hopper 5 that cooperates with the material shaking mechanism to prevent sugarcane from overflowing. This ensures that the collecting hopper 5 can still receive sugarcane normally when the material shaking mechanism is operating, without affecting the harvesting process.

[0050] Example 4

[0051] This embodiment is based on the second embodiment, in which a shaking-type flexible sugarcane collecting bucket is installed on the sugarcane harvester body 13, and further derives a collecting bucket with a shaking, pushing and unloading structure. A feed port 502 is provided above the collecting bucket 5, and rocker arms 8 and bucket cylinders 9 are hinged at the corners above the collecting bucket 5 on both sides of the two L-shaped brackets 101; the end of the bucket cylinder 9 is hinged to the middle of the rocker arm 8; the lower ends of the two L-shaped brackets 101 are respectively hinged to a first connecting rod 10, and the lower middle parts of the two L-shaped brackets 101 are respectively hinged to a second connecting rod 11, and the ends of the first connecting rod 10 and the second connecting rod 11 are respectively hinged to the middle of the rocker arm 8 and the end of the rocker arm 8; the upper ends of the two L-shaped brackets 101 are hinged to a push-out cylinder 12, and the other end of the push-out cylinder 12 is hinged to the middle of the second connecting rod 11.

[0052] Figure 4 As shown, the rear of the main body of the sugarcane harvester 13 is fixed to the support 1, and the two ends of the connecting rod are respectively hinged on the L-shaped bracket 101 and the rocker arm 8 to form a quadrilateral structure. The collecting bucket 5 is hinged between the swing bracket 7 and the rocker arm 8, and the two ends of the pushing cylinder 12 are respectively hinged on the L-shaped bracket 101 and the connecting rod. When the material is shaken and needs to be unloaded, the pushing cylinder 12 can push out the rocker arm 8, the collecting bucket 5 and the bucket cylinder 9 as a whole, so that the device avoids the fan at the upper rear of the sugarcane harvester 13, so as to realize the bucket unloading action; the two ends of the bucket cylinder 9 are respectively hinged on the collecting bucket 5 and the rocker arm 8, and the bucket can be flipped and unloaded when the bucket cylinder 9 is actuated.

[0053] 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.
