Description

Technical Field

[0001] The invention belongs to the field of agricultural machinery and relates to a reversible plow, in particular to a sequential hydraulic reversible deep tillage plow. Background Art

[0002] Land is the basic resource and condition for human survival. Arable land is needed in the process of growing crops. Arable land is the most basic and important work link in agricultural production. The purpose of arable land is to improve the soil structure and make it suitable for farming.

[0003] Deep plowing is a farming technique that has been gradually promoted in recent years. It is an important measure to resist natural disasters such as drought and flood. At the same time, deep plowing can thicken the tillage layer, prevent and control pests and diseases, weeds, store water and retain moisture, improve soil organic matter, resist drought and flood disasters, and also improve land salinity. Deep plowing can break the plow bottom layer and replace the original planting layer soil with the deep soil, and bring the lower soil with rich nutrients and few pests and diseases to the upper layer as a new planting layer to achieve soil recycling. Deep plowing is conducive to improving the soil environment and achieving conditions conducive to the growth of crops.

[0004] The current deep plowing plough needs to be pulled by a tractor with greater power and consumes relatively high energy during operation.

[0005] A sequential hydraulic reversible deep tillage plow with a small working load has been developed, which can not only realize deep tillage operations, but also can be towed by machines with smaller power. Summary of the invention

[0006] The present invention proposes a sequential hydraulic reversible deep tillage plough that can turn the soil to a depth of more than 50 cm with a small operating load. The specific technical solution is as follows:

[0007] A sequential hydraulic reversible deep tillage plow comprises a main beam (2), characterized in that: at least one set of soil turning mechanisms is arranged on the main beam (2), the soil turning mechanisms include a shallow turning mechanism and a deep turning mechanism, and the shallow turning mechanism and the deep turning mechanism are connected to the main beam (2) via a suspension frame, the shallow turning mechanism and the deep turning mechanism have different soil entry depths, that is, the shallow turning mechanism operates in a shallower layer of soil, and the deep turning mechanism operates in a deeper layer of soil, and the soil entry travel route of the shallow turning mechanism and the soil entry travel route of the deep turning mechanism are on two parallel lines.

[0008] The shallow turning mechanism can be inserted into the soil to a depth of 30 cm, while the deep turning mechanism can be inserted into the soil to a depth of 60 cm.

[0009] The deep-turning mechanism's earth-entering walking route coincides with the shallow-turning mechanism's earth-entering walking route.

[0010] In actual use: two groups of soil turning mechanisms are provided, and the two groups of soil turning mechanisms are arranged in sequence, that is, the first group is arranged on a walking route, and the second group is arranged on a parallel non-overlapping walking route.

[0011] Both the shallow turning mechanism and the deep turning mechanism include a plow body, namely a main plow body A of the shallow turning mechanism and a main plow body B of the deep turning mechanism, and the plow body of the shallow turning mechanism and the plow body of the deep turning mechanism may be the same or different in size.

[0012] The main plow body A and the main plow body B can be in the form of a mirror or bars according to soil conditions. The main plow body A and the main plow body B can be the same or different, and the sizes can also be the same or different.

[0013] The shallow turning mechanism comprises: a plow fixing plate A (3), a plow column A (7) and a main plow body A (4), wherein the plow fixing plate A (3) is fixed on a main beam (2), and the main plow body A (4) and the plow fixing plate A (3) are connected via the plow column A (7), that is, the plow fixing plate A (3) and the main plow body A (4) are fixed at two ends of the plow column A (7) respectively.

[0014] An anti-overload bolt (13) is provided between the plow column A (7) and the plow fixing plate A (3).

[0015] The deep plowing mechanism comprises: a plow fixing plate B (6), a plow column B (8) and a main plow body B (5), wherein the plow fixing plate B (6) is fixed on a main beam (2), and the main plow body B (5) and the plow fixing plate B (6) are connected via the plow column B (8), that is, the plow fixing plate B (6) and the main plow body B (5) are fixed at two ends of the plow column B (8) respectively.

[0016] An anti-overload bolt (13) is provided between the plow column B (8) and the plow fixing plate B (6).

[0017] An auxiliary plow body (10) is provided at the front of the plow body, that is, an auxiliary plow body (10) is provided in front of the plow body of both the shallow plow and the sequential hydraulic reversing deep plow, and the auxiliary plow body (10) is connected to the main beam (2) through a plow column C (9).

[0018] The traction mechanism includes a suspension frame, and a traction center adjustment device is provided between the suspension frame and the main beam. By providing the traction center adjustment device, the eccentric traction state of the plow when being pulled can be adjusted. Conventional deep plows can only improve this eccentric traction by adjusting the tractor wheelbase. This device can be adjusted during operation, which improves the convenience of adjustment.

[0019] Compared with the prior art, the present invention has the advantages of simple structure, relatively uniform force on various mechanisms of the tool during operation, small load on each mechanism, and no strict requirements on the mechanism and material. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Both the shallow turning mechanism and the deep turning mechanism include a plow body, namely a main plow body A of the shallow turning mechanism and a main plow body B of the deep turning mechanism, and the plow body of the shallow turning mechanism and the plow body of the deep turning mechanism may be the same or different in size.

[0030] The shallow turning mechanism comprises: a plow fixing plate A (3), a plow column A (7) and a main plow body A (4), wherein the plow fixing plate A (3) is fixed on a main beam (2), and the main plow body A (4) and the plow fixing plate A (3) are connected via the plow column A (7), that is, the plow fixing plate A (3) and the main plow body A (4) are fixed at two ends of the plow column A (7) respectively.

[0032] In actual operation, at least two sets of soil turning mechanisms are provided, and the soil turning mechanisms are arranged in sequence from front to back. The following is an example of two sets of soil turning mechanisms. First, a shallow trench is opened on the ground, that is, Figure 6 On the left side of the middle A part (not shown in the figure), the first set of tillage mechanisms includes a shallow tillage mechanism and a deep tillage mechanism, and the shallow tillage mechanism is arranged at the front, and the deep tillage mechanism is arranged at the rear. The main plow body A (4) of the shallow tillage mechanism at the front first enters the soil to till the shallow soil, forming a groove on the ground. The tilled soil is turned into the shallow groove opened in advance, and then the main plow body B (5) of the deep tillage mechanism at the rear continues to till the soil deeper in the groove opened by the shallow tillage mechanism. Thus, the first set of tillage mechanisms forms a groove on the ground as shown in FIG.

The plow fixing plate (14) is the plow fixing plate A (3) and the plow fixing plate B (6), and the plow post (15) is the plow post A (7) and the plow post B (8); that is, an anti-overload bolt (13) is provided between the plow post A (7) and the plow fixing plate A (3), and an anti-overload bolt (13) is provided between the plow post B (8) and the plow fixing plate B (6).
