Description

Technical Field

[0001] This utility model belongs to the field of planting machine technology, and specifically relates to a planting machine uprighting mechanism. Background Technology

[0002] A transplanter is a planting machine that can plant seedlings according to certain agronomic requirements. The most common types include the following: seedling guide tube transplanter, duckbill transplanter, and hanging cup transplanter. Each of these transplanters has its own characteristics and is suitable for different crops and operational needs.

[0003] Currently, seedling guide tube transplanters have a major drawback: after the seedlings are released from the guide tube, before or during soil covering, the seedlings tend to tilt (generally tilting backward or to the sides), which affects the planting quality. Utility Model Content

[0004] This utility model provides a planter uprighting mechanism, which can solve the problems pointed out in the background art.

[0005] A seedling straightening mechanism includes two straightening drive belts, each with a plurality of straightening limiting members. Driven by the straightening drive belts, the straightening limiting members on both sides straighten and limit the seedlings.

[0006] Preferably, the straightening limiting member is an elastic straightening length member, one end of which is fixedly connected to the straightening transmission belt.

[0007] Preferably, the elastic straightening condition is a spring or an elastic rod.

[0008] Preferably, the upper end of the elastic straightening length is fixedly connected to the straightening transmission belt, and its lower end is inclined inward.

[0009] Preferably, the angle between the elastic straightening condition and the vertical plane is 0-20 degrees.

[0010] Preferably, the straightening transmission belt is provided with a plurality of perforated fasteners, and the straightening limiting member is fixed to the perforated fasteners by bolts.

[0011] Preferably, the straightening drive belt is a chain drive belt.

[0012] Preferably, the chain drive belt includes a power input sprocket and at least one drive sprocket.

[0013] Preferably, the chain drive belt includes two drive sprockets, and a stable triangular transmission structure is formed between the power input sprocket and the two drive sprockets.

[0014] Preferably, the power input sprocket achieves power input through a transmission reversing box.

[0015] Beneficial effects: This utility model provides a straightening mechanism for a planting machine. The design of the straightening mechanism can effectively prevent seedlings from tilting during the planting process and improve the planting quality. Attached Figure Description

[0021] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0022] Example 1: As Figure 1-3 As shown in the figure, the planting machine straightening mechanism provided in this embodiment of the utility model includes two straightening transmission belts 1, that is, the two sides of the lower end of the seedling guide tube 5. The straightening transmission belt 1 is provided with a plurality of straightening limiting members 2. Under the drive of the straightening transmission belt 1, the straightening limiting members 2 on both sides straighten and limit the seedlings.

[0023] Specifically, the straightening limiting member 2 is an elastic straightening long condition, one end of which is fixedly connected to the straightening transmission belt 1. The elastic straightening long condition is a spring or an elastic rod. The elastic straightening long condition can limit the seedling and also has a certain elastic deformation and movement, avoiding hard contact and preventing damage to the seedling.

[0024] Specifically, the straightening transmission belt 1 is provided with several perforated fixing parts 3, and the straightening limiting part 2 is fixed on the perforated fixing parts 3 by bolts.

[0025] Specifically, the straightening drive belt 1 can be a chain drive belt, which includes a power input sprocket 11 and at least one transmission sprocket 12.

[0026] In this embodiment, the chain drive belt includes two drive sprockets 12, and the power input sprocket 11 and the two drive sprockets 12 form a stable triangular transmission structure. The two drive sprockets 12, the power input sprocket 11 and the transmission reversing box 4 are all mounted on the mechanism frame 13.

[0027] In some instances, the upper end of the elastic straightening length conditioner is fixedly connected to the straightening transmission belt 1, and its lower end is inclined inward. The elastic straightening length conditions on both sides are inclined to the side, which is conducive to matching the shape of the seedling, and is more conducive to limiting the straightening and avoiding damage to the seedling. The angle between the elastic straightening length conditioner and the vertical plane is 0-20 degrees.

[0028] The design principle or operation method of this utility model is as follows: the seedling is limited by the straightening limiters 2 on both sides, and the straightening transmission belt 1 moves synchronously with the planting machine. The straightening limiters 2 on both sides exert a forward force on the seedling, which also prevents the seedling from tilting backward.

[0029] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
