Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a bucket adjustment component for a hand-propelled multifunctional harvester. Background Art

[0002] As an important agricultural machinery, hand-push harvester can quickly and efficiently complete the harvesting task of crops such as rice, wheat, corn, etc., and is especially suitable for fields with complex terrain or small area.

[0003] However, crops growing under natural conditions cannot always maintain an ideal upright state. Factors such as strong winds, heavy rains, pests and diseases may cause crops to tilt to varying degrees or even fall over in large areas.

[0004] When crops fall over, traditional push-type harvesters have difficulty effectively picking up and processing the parts of crops that are close to the ground or tilted due to their fixed angle and single-direction cutting mechanisms, resulting in frequent missed harvesting. Especially when the crop stems are in close contact with the ground or intertwined with each other, the guide components of the harvester may not be able to fully contact and guide these crops into the harvesting channel, thus affecting the overall harvesting quality and efficiency. Utility Model Content

[0005] The utility model aims to provide a bucket adjustment component for a hand-propelled multifunctional harvester, so as to solve the problem that lodged crops are easily missed from being harvested.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A bucket adjustment assembly for a hand-pushed multifunctional harvester comprises a frame and a bucket, wherein the bucket is arranged at the front end of the frame, the bucket comprises a first diverter portion and a second diverter portion, the first diverter portion and the second diverter portion are both movably connected to the bucket, the first diverter portion comprises a first guide surface, the first guide surface is formed with a first tip, the second diverter portion comprises a second guide surface, a material channel is formed between the first guide surface and the second guide surface, the second guide surface is formed with a second tip, and a feeding port is formed between the first tip and the second tip; wherein, after the first diverter portion and the second diverter portion are adjusted, the ray emitted by the first tip along the guiding direction of the first guide surface has an intersection with the ray emitted by the second tip along the guiding direction of the second guide surface.

[0008] Further, along the height direction of the bucket, the high side of the first guide surface is inclined outwardly relative to the low side thereof, and the high side of the second guide surface is inclined outwardly relative to the low side thereof.

[0009] Further, along the guiding directions of the first guiding surface and the second guiding surface, the high sides of the first guiding surface and the second guiding surface gradually bulge inwards.

[0010] Furthermore, an end of the first guide surface away from the first tip gradually approaches an end of the second guide surface away from the second tip.

[0011] Further, the first tip is formed on a lower side of the first guide surface, and the second tip is formed on a lower side of the second guide surface.

[0012] Further, along the guiding directions of the first guiding surface and the second guiding surface, the heights of the lower sides of the first guiding surface and the second guiding surface gradually decrease.

[0013] Furthermore, the first pointed end is bent outward relative to the first guide surface, and the second pointed end is bent outward relative to the second guide surface.

[0014] Furthermore, a first arc portion is formed between the first tip and the first guide surface, a second arc portion is formed between the second tip and the second guide surface, and the centers of the first arc portion and the second arc portion are both facing outwards.

[0015] The advantages of the bucket adjustment assembly for a hand-pushed multifunctional harvester described in the utility model over the prior art are:

[0016] Through the movable connection between the first diverter part and the second diverter part and the bucket, the operator can accurately adjust the positions of the first diverter part and the second diverter part according to the specific angle and height of the crop lodging, ensuring that the feeding port formed by the first tip and the second tip can accurately capture the lodged crops and effectively guide them into the material channel constructed by the first guide surface and the second guide surface, thereby greatly reducing the probability of missed cutting.

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Embodiment 1:

[0025] like Figure 1-2 As shown, the present embodiment provides a bucket 20 adjustment assembly for a hand-pushed multifunctional harvester, including a frame 10 and a bucket 20. The frame 10 is usually made of high-strength steel to ensure that the overall structural rigidity is sufficient to cope with various complex farmland operating environments. The frame 10 is designed with precise mounting interfaces and guide mechanisms for fixing and flexibly adjusting the position and angle of the bucket 20.

[0026] The main body of the bucket 20 is made of wear-resistant material and is arranged at the front end of the frame 10 through movable connecting parts. For example, the first diverter part 201 and the second diverter part 202 can be connected to the main body of the bucket 20 through precise mechanical hinges. The operator can change the angle and position of the diverter part by adjusting the fasteners on the hinge (such as bolts, knobs or hydraulic systems). Of course, the swing and extension of the first diverter part 201 and the second diverter part 202 can also be controlled by the pneumatic or hydraulic system integrated into the harvester.

[0027] The bucket 20 includes a first diverter portion 201 and a second diverter portion 202 which can move independently or in coordination. The first diverter portion 201 has a first guide surface 2011, and a sharp first tip 2012 is formed at the front end thereof, which helps to cut and guide the crops to flow to the middle material channel during the harvesting process; the second diverter portion 202 is configured with a second guide surface 2021 that cooperates with each other, and a second tip 2022 is also provided at the front end. The distance between the two tips and their angles relative to the ground can be adjusted to form an ideal feeding port that adapts to different crop heights and lodging conditions.

[0028] When the operator adjusts the first diverter 201 and the second diverter 202 according to the actual situation, it is ensured that the rays emitted by the first tip 2012 along the direction of the first guide surface 2011 and the rays emitted by the second tip 2022 along the direction of the second guide surface 2021 have an intersection in a certain working state. This design feature ensures that no matter at what angle or height the crops fall, they can be accurately captured and introduced into the material channel by the bucket 20 of the harvester, thereby greatly improving the adaptability and harvesting efficiency of the hand-pushed multifunctional harvester to various complex field environments and fallen crops, and effectively reducing the loss of missed harvesting caused by the tilted crops.

[0029] Embodiment 2:

[0030] like Figure 3 As shown, on the basis of the above-mentioned embodiment, along the height direction of the bucket 20, the high side of the first guide surface 2011 is inclined outwardly relative to its low side, and the high side of the second guide surface 2021 is inclined outwardly relative to its low side. Specifically, starting from the tip, the angle between the first guide surface 2011 and the horizontal plane gradually increases as the height increases, forming a trend of slanting outward; similarly, the second guide surface 2021 also has a similar design.

[0031] Such a structural design enables that after the first diversion part 201 and the second diversion part 202 are adjusted, when the harvester passes through fallen crops, whether it is the upper or lower part of the crop stems, or even the part growing close to the ground, they can be better contacted and guided into the material channel by the first guide surface 2011 and the second guide surface 2021, thereby effectively preventing the occurrence of missed cutting.

[0032] Embodiment 3:

[0033] like Figure 4 As shown, based on the above embodiment, along the guiding direction of the first guiding surface 2011 and the second guiding surface 2021, the high sides of the first guiding surface 2011 and the second guiding surface 2021 gradually bulge inwards, that is, the first diverter 201 and the second diverter 202 respectively have a guiding surface design that bends toward the inside of the material channel (i.e. bulges inwards). As the guiding surface extends inwards from the tip along the direction in which the crop enters the bucket 20, its height gradually increases and bends inwards to form a shape similar to a "parabola" or "arc".

[0034] For example, in actual application, when the harvester passes over fallen crops, this design enables the first guide surface 2011 and the second guide surface 2021 to better wrap and pick up crops that are tilted or growing close to the ground. The outward tilting design ensures effective contact with the crops, while the inward protruding part can gradually converge the crops it contacts and guide them into the feeding port like an arm, and then enter the material channel for subsequent cutting, threshing and other processing processes.

[0035] Such a design not only improves the harvesting efficiency of fallen crops and reduces the loss due to missed harvesting, but also can flexibly adapt to different types of field working environments and crop lodging conditions by adjusting the angles of the first diversion part 201 and the second diversion part 202 according to actual conditions.

[0036] Embodiment 4:

[0037] On the basis of the above embodiment, the end of the first guide surface 2011 away from the first tip 2012 and the end of the second guide surface 2021 away from the second tip 2022 gradually approach each other. Specifically, when observing inward from the two tips of the bucket 20, the first guide surface 2011 of the first diverter portion 201 and the second guide surface 2021 of the second diverter portion 202 gradually decrease in distance until they approach each other during the process of extending toward the inside of the material channel.

[0038] This structure is similar to the shape of a "trumpet", so that no matter what angle or height the fallen crops are at, they can be surrounded by these two gradually narrowing guide surfaces and guided into the feeding port, effectively preventing the crops from sliding from both sides and causing missed harvesting.

[0039] Embodiment 5:

[0040] Based on the above embodiment, the first tip 2012 is formed on the lower side of the first guide surface 2011, and the second tip 2022 is formed on the lower side of the second guide surface 2021, which means that the first guide surface 2011 of the first diverter portion 201 and the second guide surface 2021 of the second diverter portion 202 respectively form the first tip 2012 and the second tip 2022 for guiding crops at their lower positions.

[0041] Specifically, this design allows the bucket 20, when in contact with fallen crops, to have the first tip 2012 and the second tip 2022 located at a lower position to be closer to the ground or the portion of the crops growing close to the ground, thereby effectively cutting and picking up these crops and reducing missed cutting caused by insufficient height.

[0042] For example, when the harvester passes through a severely lodged rice field, since the first tip 2012 and the second tip 2022 are arranged on the lower side of their respective guide surfaces, even if most of the crop stems are close to the ground, they can be accurately contacted by the two tips and guided into the material channel, ensuring the effective harvesting of the lodged crops and improving the overall harvesting quality and efficiency. At the same time, such a design is more adaptable to the complex and changeable farmland environment, helps to reduce the workload of agricultural machinery operators, and improves the mechanization level of agricultural production.

[0043] Embodiment 6:

[0044] Based on the above embodiment, a structure is designed in which the height of the lower side of the first guide surface 2011 and the second guide surface 2021 gradually decreases along the guiding direction of the first guide surface 2011 and the second guide surface 2021 (i.e., the direction extending from the tip toward the inside of the bucket 20).

[0045] For example, the first guide surface 2011 starts from a sharp first tip 2012, and as it moves toward the internal material channel, its side close to the ground gradually tilts downward to form a slope-like structure; similarly, the second guide surface 2021 also has a similar design, and as it starts from the second tip 2022 and extends toward the inside of the material channel, the height of its lower side portion gradually decreases.

[0046] This design greatly enhances the harvester's adaptability to fallen crops. In actual operation, even if the crops fall to the ground or tilt at a large angle, the lower and gradually lowered guide surface can be closer to the crop growth state, so that no matter what position the crops are in, they can be effectively picked up and introduced into the harvester through the gradually narrowing feeding port for subsequent processing, thereby significantly reducing the probability of missed harvesting and improving the overall harvesting efficiency and effect.

[0047] Embodiment 7:

[0048] Based on the above embodiment, the first tip 2012 is bent outward relative to the first guide surface 2011, and the second tip 2022 is bent outward relative to the second guide surface 2021. Specifically, the first guide surface 2011 of the first diverter portion 201 is not straight and perpendicular to the direction of the guide surface at its end (i.e., the position where the first tip 2012 is formed), but forms a structure that is slightly bent outward; similarly, the second guide surface 2021 of the second diverter portion 202 also adopts a similar outward bending design at the position where the second tip 2022 is formed.

[0049] This structure can be imagined as a pair of slightly opened scissors or pliers, with the first tip 2012 and the second tip 2022 located at the front end of their respective guide surfaces, and both of them are slightly deflected (bent outward) away from each other. This design allows the two tips to better surround the crop stems when the harvester is processing lodged crops, and whether the crops are upright or tilted, they can be effectively picked up and introduced into the material channel, greatly reducing the possibility of missing harvesting.

[0050] Embodiment 8:

[0051] On the basis of the above embodiment, a first arc portion 2013 is formed between the first tip 2012 and the first guide surface 2011, and a second arc portion 2023 is formed between the second tip 2022 and the second guide surface 2021. The centers of the first arc portion 2013 and the second arc portion 2023 are both facing outwards. Specifically, the first guide surface 2011 of the first diverter 201 is bent inward at its tip portion to form a semicircular or approximately semicircular first arc portion 2013, and the center of this arc portion is located outside the first guide surface 2011. Similarly, the second guide surface 2021 of the second diverter 202 also forms a similar second arc portion 2023 at its tip position, and its center is also located outside the second guide surface 2021.

[0052] This structure is like an inverted spoon, and the head of the spoon (i.e., the first tip 2012 and the second tip 2022) is not in a straight line, but in an arc shape, and the depressions of the two arc parts are both directed to the outer space of the bucket 20. Such a design enables the first arc portion 2013 and the second arc portion 2023 to effectively wrap and guide the crop stems, whether upright or tilted, into the material channel when the harvester contacts the fallen crops.

[0053] Working principle:

[0054] When the device is in use, when the hand-pushed multifunctional harvester enters the area to be harvested, the operator adjusts the movable connection structure between the first diverter 201 and the second diverter 202 and the bucket 20 according to the specific situation of crop lodging, so that the first guide surface 2011 and the second guide surface 2021 can be adaptively adjusted in angle and spacing. The first tip 2012 and the second tip 2022 are key parts of the introduction, located at the lower side of each guide surface, and both are designed to be bent outward, so that the lodged or tilted crops can be better wrapped.

[0055] As the harvester moves forward, the arc structure formed by the first tip 2012 bending outward along the first guide surface 2011 (i.e., the first arc portion 2013) and the arc structure formed by the second tip 2022 bending outward along the second guide surface 2021 (i.e., the second arc portion 2023) can better fit the part of the crop growing on the ground or close to the ground, converge the crop stems inward from both sides and guide them to the feeding port.

[0056] In addition, along the guiding direction of the first guide surface 2011 and the second guide surface 2021, their low side heights gradually decrease, ensuring that even the part closest to the ground can be effectively picked up. At the same time, the centers of the first arc portion 2013 and the second arc portion 2023 are arranged outward, so that the entire device has better inclusiveness and guidance, and no matter how the crops are tilted, as much as possible can be introduced into the material channel.

[0057] When multiple illustrative embodiments are mentioned in this specification, it means that the specific structure described in conjunction with the embodiment is included in at least one embodiment generally described in this application. The same expression appearing in multiple places in the specification does not necessarily refer to the same embodiment. Further, when a structure is described in conjunction with any embodiment, it is claimed that the structure is implemented in conjunction with other embodiments within the scope of the utility model.
