Description

Technical Field

[0001] This utility model belongs to the field of sealing machine technology, specifically, it relates to an automatic adjustable diversion device for sealing machines. Background Technology

[0002] In agricultural planting and engineering construction, soil sealing machines are key equipment for achieving uniform soil coverage, and their operational quality directly affects the crop growth environment or the stability of engineering foundations. During soil sealing operations, the proper distribution of soil is a core requirement. Excessive soil accumulation leads to uneven compaction within the trench, while insufficient distribution fails to achieve effective coverage. Against this backdrop, the diversion device becomes a core component of the soil sealing machine. Its main function is to distribute the delivered soil to both sides or specific areas as needed through diversion chambers, guide pipes, and other structures. For example, symmetrically arranged outlet holes can achieve left-right soil diversion, or multiple sets of guide pipes can precisely control the coverage area, thereby avoiding localized accumulation, ensuring uniform soil sealing, and ultimately improving operational efficiency and quality.

[0003] Before the tractor begins operation, the distance between the two diversion chambers should be adjusted according to the row spacing in the crop field. During operation, when the tractor is working along the ridges, the diversion device needs to be close to the ground to ensure that the soil accurately covers the crop roots or both sides of the ridge. When the tractor reaches the end of each ridge and prepares to turn around, the working trajectory changes from a straight line to an arc, and the relative angle between the machine and the ground changes drastically. If the diversion device remains at its original height, the centrifugal force during the turn will cause the edge of the device to scrape against the ground, ridge, or soil in unoperated areas. This can result in uneven soil accumulation, or even damage to the guide plate, soil outlet, and other precision structures of the diversion device due to the hard impact, and may even crush seedlings in adjacent ridges. In addition, during the turning process, the tractor temporarily leaves the operating state, and raising the device can reduce the contact area with the ground and reduce mechanical wear. At the same time, a moderate raise can provide more vertical space for the machine to turn, avoid interference between the device and the tractor's rear wheels or other auxiliary equipment, and ensure a smooth turning operation. Once the machine body has completed its turn and aligned with the next ridge's working path, the device returns to its working height, restoring precise diversion and ensuring the continuity and quality of continuous operation. This dynamic adjustment of "lifting and returning" is key to adapting to the intermittent operation requirements of ridge cultivation. Meanwhile, in straight-line operations, the height of the diversion bin needs to be adjusted in real time to improve the soil sealing effect.

[0004] In existing earth sealing machines, the lifting and diversion devices are usually adjusted manually or mechanically. Manual adjustment increases the labor intensity of workers and reduces work efficiency, while existing mechanical lifting is prone to wear and tear during use, and its automation level is insufficient and its adaptability is limited.

[0005] Chinese patent application CN2022215220131 discloses a rotary tiller for sealing cotton plants. The machine includes a frame connected to a tractor. The frame is equipped with a walking device, a power transmission device, rotary tillers on both sides of the frame, a conveying device, and a diverting device. The power transmission device is driven by the tractor's power unit, and is driven by the rotary tillers. The rotary tillers are driven by the conveying device. The tractor pulls the frame, which moves via the walking device. This invention features a reasonable structural design, a high degree of automation, and the ability to seal multiple rows of seedlings with good sealing effect.

[0006] However, in this patent, the spacing in the diversion device is adjusted manually, and there is no mechanism to lift the diversion device when turning or making a U-turn, which affects its service life. Utility Model Content

[0007] The main technical problem to be solved by this utility model is to provide an automatic adjustable diversion device for a soil sealing machine with a simple overall structure that can automatically adjust the lifting and returning of the diversion device during the operation of the soil sealing machine, adapt to intermittent operation in the ridge planting mode, extend the service life of the machine, reduce the maintenance rate, and improve the use effect.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] An automatic adjustable diversion device for a soil sealing machine includes a fixed L-shaped square tube installed on one side of a chassis support. A manual adjustment device is provided on the fixed L-shaped square tube, and an automatic adjustment device is provided on the fixed L-shaped square tube near the manual adjustment device. The other end of the manual adjustment device is rotatably connected to a first diversion chamber, and the other end of the automatic adjustment device is rotatably connected to a second diversion chamber. The first and second diversion chambers are symmetrically arranged, and the other ends of the first and second diversion chambers are rotatably connected to the same connecting groove, which is fixedly connected to the chassis support.

[0010] The automatic adjustment device includes a hydraulic cylinder rotatably connected to a fixed L-shaped square tube, and the power output end of the hydraulic cylinder is rotatably connected to the second diversion chamber.

[0011] The following are further optimizations of the above technical solution by this utility model:

[0012] The manual adjustment device includes a first fixed sleeve fixedly installed on one side of the upper surface of the fixed L-shaped square tube, a first rotating rod sleeved inside the first fixed sleeve, and a plurality of first through holes opened on the outer surface of the first rotating rod.

[0013] Further optimization: The outer surface of the first fixing sleeve is threaded with a first tightening bolt, and the outer diameter of the first tightening bolt matches the first through hole.

[0014] Further optimization: A second fixing sleeve is fixedly installed at the end of the first rotating rod away from the chassis support, and the second fixing sleeve is arranged perpendicular to the first rotating rod.

[0015] Further optimization: A second rotating rod is inserted into the second fixed sleeve, and multiple second through holes are opened on the outer surface of the second rotating rod.

[0016] Further optimization: A second tightening bolt is threaded onto the outer surface of the second fixing sleeve, and the outer diameter of the second tightening bolt matches the second through hole.

[0017] Further optimization: A connecting block is fixedly installed at the upper end of the second rotating rod.

[0018] Further optimization: Two symmetrically spaced first ear plates are vertically arranged on one side of the first diversion chamber near the connecting block. A first rotating shaft is fixedly installed on the two first ear plates, and the other end of the connecting block is sleeved on the outer surface of the first rotating shaft.

[0019] Further optimization: A fixed shaft is vertically arranged on the outer side of the fixed L-shaped square tube near the position of the first rotating rod, and the tail end of the oil cylinder is rotatably connected to the fixed shaft through a tailstock.

[0020] Further optimization: Two symmetrically arranged second ear plates are fixedly installed on the side of the second diversion chamber opposite to the first diversion chamber. The two second ear plates correspond to the positions of the two first ear plates. A second rotating shaft is fixedly installed on the two second ear plates. The power output end of the oil cylinder is sleeved on the outer surface of the second rotating shaft to achieve a rotating connection.

[0021] This utility model adopts the above-mentioned technical solution, with ingenious design and reasonable structure. It can automatically raise and retract the second diversion chamber on one side of the diversion device during the operation of the sealing machine. This avoids the situation where the working trajectory changes from a straight line to an arc when the sealing machine needs to turn at the end of each ridge to continue working, and the relative angle between the machine body and the ground changes drastically, which could lead to collisions. This reduces the maintenance rate of the sealing machine during use, extends its service life, improves the overall operating efficiency, and is convenient to use. At the same time, during the straight operation of the sealing machine, it is convenient for the staff to adjust the position of the diversion chamber at any time to improve the sealing effect.
