Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a single-row farmland management machine. Background Art

[0002] As an agricultural machinery product designed for small cultivated land such as orchards, vegetable gardens, greenhouses, hilly slopes, etc., the single-row farmland management machine can effectively reduce the labor intensity of farmers and improve agricultural production efficiency.

[0003] However, the existing single-row farmland management machine still has some shortcomings, such as

[0004] At the same time, most of the existing single-row farmland management machines use a wheeled walking mechanism. In order to operate in the ridge ditch, the width of the single-row farmland management machine is relatively narrow, and the lateral stability of the single-row farmland management machine is poor. It is very easy to have problems such as tilting and overturning, and it is also easy to sink into the ground, affecting normal work. In order to avoid problems such as tilting and overturning, farmers need to stand on one side of the single-row farmland management machine, and while walking to follow the movement of the single-row farmland management machine, always hold the handrail sideways to provide necessary support, control and adjustment to the single-row farmland management machine, which greatly increases the labor intensity of farmers and reduces the working efficiency of the farmland management machine.

[0005] In addition, in order to facilitate turning, the working mechanism of the existing single-row farmland management machine is usually articulated with the walking mechanism, and the working mechanism and power device of the existing single-row farmland management machine are usually located at the front and rear of the whole machine respectively, and the weight of the power device is not much different from the weight of the working mechanism. Therefore, when the working mechanism at the front of the single-row farmland management machine encounters hard objects such as stones during operation, it is very easy to cause problems such as warping and bouncing, which affects the operation quality and efficiency of the single-row farmland management machine. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a single-row farmland management machine which is not prone to tilting, has stable walking, can reduce the labor intensity of farmers and improve work efficiency.

[0007] The utility model is realized through the following technical scheme, which provides a single-row farmland management machine, including a crawler walking mechanism and a frame. The frame is rotatably connected to the crawler walking mechanism, the frame is connected to an operating mechanism, the crawler walking mechanism is connected to a carrying mechanism on a side away from the operating mechanism, and the left side and / or right side of the crawler walking mechanism are connected to a supporting mechanism.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: compared with the wheeled traveling mechanism of the existing single-row farmland management machine, the crawler traveling mechanism can increase the contact area between the traveling mechanism and the ground, thereby improving the lateral support capacity of the single-row farmland management machine, reducing the possibility of the single-row farmland management machine tilting, and at the same time, it is not easy for the traveling mechanism to sink into the ground in the furrow;

[0009] The support mechanism can support the side of the single-row farmland management machine, further reducing the possibility of the single-row farmland management machine tilting or overturning, and improving the stability of the single-row farmland management machine during work. Farmers do not need to hold the handrails, and the single-row farmland management machine can also move forward stably, reducing the labor intensity of farmers;

[0010] Through the carrying mechanism, the single-row farmland management machine can carry farmers and move together during its forward movement, which greatly reduces the walking distance of farmers and further reduces the labor intensity of farmers.

[0011] Preferably, the supporting mechanism includes an eleventh mounting component connected to the crawler walking mechanism, and the eleventh mounting component is connected to a pedal and / or a seat.

[0012] Preferably, the frame is connected to a power unit and a transmission device, and the frame is rotatably connected to the crawler walking mechanism through a first rotating shaft. The center of gravity of the transmission device is located between the first rotating shaft and the operating mechanism. When the frame is horizontal, the center of gravity of the power unit is located directly above the first rotating shaft or between the first rotating shaft and the operating mechanism.

[0013] The beneficial effect of adopting the above-mentioned preferred technical solution is that: since the center of gravity of the transmission device is set between the first rotating shaft and the operating mechanism, and the center of gravity of the power device is set directly above the first rotating shaft or between the first rotating shaft and the operating mechanism, when the operating mechanism encounters a hard object, the weight of the power device and the transmission device can be used to enable the operating mechanism to obtain sufficient downward force, thereby reducing the occurrence of adverse phenomena such as warping and bouncing of the operating mechanism. When the single-row farmland management machine is carried by farmers, it can ensure that the operating mechanism will not warp due to the weight of the farmers, thereby ensuring that the single-row farmland management machine can work normally.

[0014] Preferably, when a support mechanism is connected to the left or right side of the crawler walking mechanism, the center of gravity of the power device and the transmission device is biased toward one side of the support mechanism.

[0015] The beneficial effect of adopting the above-mentioned preferred technical solution is that by biasing the center of gravity of the power device and the transmission device toward one side of the support mechanism, the lateral stability of the single-row farmland management machine can be further improved.

[0016] Preferably, the support mechanism includes a fifth mounting component connected to the crawler walking mechanism, and the fifth mounting component is connected to a support wheel.

[0017] Preferably, the fifth mounting component is connected to the seventh mounting component via the sixth mounting component, the seventh mounting component is connected to the ninth mounting component via the eighth mounting component, and the ninth mounting component is connected to the support wheel.

[0018] Preferably, the ninth mounting component is slidably connected to the tenth mounting component, the support wheel is connected to the tenth mounting component, the tenth mounting component is provided with a first connecting portion and a first limiting portion, and the first connecting portion is sleeved with a first elastic component.

[0019] Preferably, the sixth mounting component and the eighth mounting component are both hollow structures, the seventh mounting component is slidably connected to the sixth mounting component, the ninth mounting component is slidably connected to the eighth mounting component, and the sixth mounting component and the eighth mounting component are respectively connected to the second fixing component and the third fixing component.

[0020] Preferably, the inner cavity cross-section of the sixth mounting component, the inner cavity cross-section of the eighth mounting component, the seventh mounting component, and the ninth mounting component are all polygonal, the size of the inner cavity cross-section of the sixth mounting component is the same as the size of the cross-section of the seventh mounting component, and the size of the inner cavity cross-section of the eighth mounting component is the same as the size of the cross-section of the ninth mounting component.

[0021] The beneficial effect of adopting the above-mentioned preferred technical solution is that: through the sixth mounting component, the distance between the support wheel and the crawler walking mechanism can be adjusted according to the width of the ridge and the ridge platform, so that the support mechanism can adapt to ridges and ridge platforms of different widths, thereby improving the applicability of the support mechanism; through the eighth mounting component, the relative height between the bottom of the support wheel and the bottom surface of the crawler walking mechanism can be adjusted according to the height difference between the crawler walking mechanism and the ground contacted by the support wheel, so that the support wheel can fully contact the ground, ensuring that the support mechanism can effectively support the single-row farmland management machine; through the first elastic component, when the support wheel encounters hard objects or potholes during movement, it can play a shock-absorbing role, avoiding the swing and tilt of the crawler walking mechanism when the support wheel is displaced vertically according to the road conditions, and further keeping the support wheel in full contact with the ground.
