Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a small and lightweight crop harvesting machine suitable for mountainous areas. Background Technology

[0002] With the development of agricultural modernization, the application of crop harvesting machinery has become increasingly widespread, greatly improving agricultural production efficiency and reducing labor intensity.

[0003] However, in hilly and mountainous areas, large combine harvesters are difficult to operate due to small plots, complex terrain, and rugged surfaces. Therefore, some smaller push or backpack harvesters have emerged on the market. While this has addressed the issue of availability to some extent, significant shortcomings remain in practical applications.

[0004] Existing small harvesters typically have a simple structure. To control costs and weight, their wheels are often rigidly connected to the machine body, lacking effective shock absorption and cushioning. When these harvesters travel on uneven terrain, the entire machine experiences severe bumps and vibrations. This continuous vibration not only seriously affects the smoothness and comfort of operation, but more importantly, it causes the height between the cutter blade and the ground to constantly change, making it difficult to maintain a stable stubble height. This results in incomplete harvesting, a high rate of missed cuts, and uneven fields after harvesting, directly impacting the final harvest quality and economic benefits. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a small and lightweight crop harvesting machine suitable for mountainous areas. It aims to improve the problem that existing small and lightweight crop harvesting machines for mountainous areas suffer from severe machine shaking and unstable cutter height due to the lack of effective shock absorption structures when operating on uneven terrain such as mountains, thus affecting the harvesting quality. This utility model aims to provide a small and lightweight crop harvesting machine for mountainous areas with an improved structure that can effectively solve the above problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a small and lightweight crop harvesting machine suitable for mountainous areas, comprising: a harvester body, and a base, a dividing plate, a cutting blade and wheels disposed on the harvester body; a shock-absorbing component connected between the base and the wheels, and an adjustment component for adjusting the angle of the dividing plate.

[0007] The shock absorption assembly includes an upper swing arm and a lower swing arm hinged to the wheel, and a spring damper connected between the lower swing arm and the base.

[0008] Furthermore, the adjustment assembly includes a rotating shaft fixedly connected to the dividing plate, and a locking mechanism for fixing the angle of the rotating shaft. The locking mechanism includes a first toothed edge and a second toothed edge that can mesh with each other, and a first spring for driving the first toothed edge to mesh with the second toothed edge.

[0009] Preferably, the wheel is fixedly connected to a mounting plate via a collar and a fixing rod; one end of the upper swing arm and the lower swing arm are both hinged to the mounting plate, and the other end is hinged to the base; one end of the spring damper is connected to the lower swing arm via a fixing plate.

[0010] Preferably, the shock absorption assembly further includes a rotating rod, one end of which is connected to the collar and the other end of which is connected to the base.

[0011] Preferably, the harvester body is further provided with a placement plate, and the adjustment component is installed on the placement plate; the adjustment component includes a housing, the first toothed edge is disposed on the housing, and the second toothed edge is fixed to the placement plate.

[0012] Preferably, the adjustment assembly further includes a torsion block disposed on the housing, the torsion block passing through the housing and fixedly connected to the rotating shaft.

[0013] Preferably, the adjustment assembly further includes a dust cover, which is disposed outside the rotating shaft.

[0014] Preferably, the harvester body further includes an engine, which drives the cutter to rotate via a transmission assembly.

It achieves the technical effect of smooth machine movement, effectively ensuring harvesting quality and improving operational safety.

[0019] 2. This utility model, by setting an adjustment component for adjusting the angle of the dividing plate, includes a locking mechanism composed of a first toothed ridge and a second toothed ridge that can mesh with each other, solves the problem that the angle of the dividing plate of existing harvesters is fixed and cannot adapt to different growth postures of crops in mountainous areas (such as lodging), resulting in low harvesting efficiency and high crop loss rate.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please refer to Figures 1 to 5 This utility model provides a small and lightweight crop harvesting machine suitable for mountainous areas, aiming to solve the structural defects of existing harvesters in mountainous areas, such as machine bumps, unstable harvesting quality, and poor adaptability to different crop postures due to the lack of shock absorption structure.

[0029] like Figure 1 As shown, the small and lightweight crop harvesting machine suitable for mountainous areas includes a harvester body 1, a base 2 on the harvester body 1, a dividing plate 9 and a cutter blade 10 installed at the front of the base 2, and wheels 4 at the lower part of the harvester body 1. The core of this solution is that the harvester body 1 also includes a shock-absorbing component 5 connected between the base 2 and the wheels 4, and an adjustment component 8 for adjusting the angle of the dividing plate 9.

[0030] Reference Figure 2 and Figure 4 The shock absorption assembly 5 is used to absorb and buffer the impact caused by uneven ground. The shock absorption assembly 5 includes an upper swing arm 508 and a lower swing arm 504 hinged to the wheel 4, and a spring damper 506 connected between the lower swing arm 504 and the base 2. The specific connection structure is as follows: the wheel 4 is fixedly connected to the mounting plate 503 through the collar 501 and the fixing rod 502. One end of the upper swing arm 508 and the lower swing arm 504 are both hinged to the mounting plate 503, and the other end of the upper swing arm 508 and the lower swing arm 504 are hinged to the base 2. One end of the spring damper 506 is connected to the lower swing arm 504 through the fixing plate 505. In order to further enhance the stability of travel, the shock absorption assembly 5 also includes a rotating rod 507. One end of the rotating rod 507 is connected to the collar 501, and the other end is connected to the base 2.

[0031] Reference Figure 3 and Figure 5 The adjustment component 8 is used to precisely adjust the angle of the dividing plate 9 according to the growth status of the crop. The adjustment component 8 includes a rotating shaft 802 fixedly connected to the dividing plate 9, and a locking mechanism for fixing the angle of the rotating shaft 802. The locking mechanism includes a first tooth 805 and a second tooth 806 that can mesh with each other, and a first spring 807 for driving the first tooth 805 and the second tooth 806 to mesh. In order to support and operate the adjustment component 8, a placement plate 6 is also provided on the harvester body 1. The adjustment component 8 is installed on the placement plate 6. The adjustment component 8 includes a housing 804. The first tooth 805 is provided on the housing 804, and the second tooth 806 is fixed to the placement plate 6. The adjustment component 8 also includes a torsion block 803 provided on the housing 804. The torsion block 803 passes through the housing 804 and is fixedly connected to the rotating shaft 802. In order to protect the internal structure, the adjustment component 8 also includes a dust cover 801, which covers the outside of the rotating shaft 802.

[0032] To achieve smooth operation in mountainous terrain, one of the core technical solutions in this embodiment is the shock absorption component 5, which forms a suspension connection structure with buffer function between the base 2 and the wheel 4 of the harvester body 1.

[0033] Please refer to the following carefully. Figure 2 and Figure 4 The structure of the shock-absorbing component 5 allows the wheel 4 to float up and down relative to the base 2. The wheel 4 is connected to the fixed rod 502 via the collar 501. The other end of the fixed rod 502 is fixedly connected to the mounting plate 503. The mounting plate 503 is a key platform connecting the wheel assembly and the swing arm. One end of the upper swing arm 508 and the lower swing arm 504 are both hinged to the mounting plate 503, while the other end of the upper swing arm 508 and the lower swing arm 504 are hinged to the base 2. This hinged structure of the double swing arm limits the mounting plate 503 to swing up and down relative to the base 2, thus providing a motion basis for shock absorption. A fixed rod is also fixedly connected to the lower swing arm 504. One end of the spring damper 506 is connected to the fixed plate 505, and the other end is connected to the base 2. When the wheel 4 bounces upward due to uneven ground, the lower swing arm 504 swings upward and compresses the spring damper 506, which absorbs most of the impact energy, thus greatly reducing the vibration transmitted to the base 2. To further suppress the swaying of the wheel 4 during travel, the shock absorption assembly 5 is also equipped with a rotating rod 507. One end of the rotating rod 507 is connected to the collar 501, and the other end is connected to the base 2. This structural combination ensures the high stability and passability of the harvester body 1 when traveling on rugged mountain roads.

[0034] As a preferred embodiment, please refer to Figure 1 , Figure 3 and Figure 5 In order to achieve precise adjustment and reliable locking of the angle of the dividing plate 9, the harvester body 1 is also provided with a placement plate 6. The adjustment component 8 is installed on the placement plate 6. The adjustment component 8 includes a housing 804 that can be held by the operator. The first toothed ridge 805 is set on the housing 804 as the movable part of the locking mechanism, and the second toothed ridge 806 is fixed to the placement plate 6 as the fixed part of the locking mechanism. The adjustment component 8 also includes a torsion block 803 set on the housing 804. The torsion block 803 passes through the housing 804 and is fixedly connected to the rotating shaft 802 to form a transmission path of operating torque. In order to protect the rotating structure, the adjustment component 8 also includes a dust cover 801, which covers the outside of the rotating shaft 802.

[0035] As another preferred embodiment, please refer to Figure 1 In order to provide harvesting power, the harvester body 1 also includes an engine 11, which is connected to the cutter 10 through a transmission assembly to drive the cutter 10 to rotate at high speed.

[0036] As another preferred embodiment, please refer to Figure 1 To prevent straw and weeds from splashing during the harvesting process, baffles 7 are fixedly connected to both sides of the harvester body 1.

[0037] As another preferred embodiment, please refer to Figure 1 To facilitate operation and control, the harvester body 1 also includes an upwardly extending support rod 3. The upper end of the support rod 3 is provided with a rotating plate 12, and the rotating plate 12 is provided with a handle 13 for the operator to hold.

[0038] Working principle: When the operator pushes the harvester body 1 forward by holding the handle 13 inside the rotating plate 12 on the support rod 3, if the wheel 4 travels on uneven ground, the shock absorption component 5 starts to function. The wheel 4 drives the upper swing arm 508 and the lower swing arm 504 to swing relative to the base 2 through the collar 501 and the mounting plate 503. The swing of the lower swing arm 504 will compress or stretch the spring damper 506 connected between the fixed plate 505 and the base 2. The spring damper 506 absorbs most of the impact energy, so that the harvester body 1 and the cutter 10 remain relatively stable. At the same time, the rotating rod 507 restricts the swaying of the wheel 4 and ensures the stability of the movement.

[0039] Before or during harvesting, when it is necessary to adjust the angle of the dividing plate 9, the operator pulls the housing 804 of the adjusting component 8 installed on the placement plate 6 outward, so that the first tooth 805 on the housing 804 disengages from the second tooth 806 fixed on the placement plate 6, and compresses the first spring 807. Then, the torsion block 803 on the housing 804 is rotated. The torsion block 803 drives the dividing plate 9 to rotate to the required angle through the fixed connection with the rotating shaft 802. After the housing 804 is released, the first spring 807 returns to its original position, driving the first tooth 805 and the second tooth 806 to re-engage, thereby reliably locking the angle of the dividing plate 9.

[0040] When harvesting, the engine 11 is started, which drives the cutter 10 to rotate at high speed, pushing the harvester body 1 forward. The divider plate 9, with its angle adjusted, will straighten the crops and guide them to the cutting area of ​​the cutter 10. The baffles 7 on both sides block the straw and weeds that fly out during cutting. Through the coordinated action of the shock absorption component 5 and the adjustment component 8, the cutter 10 can neatly cut the effectively guided crops at a set height in a bumpy mountain environment.
