Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural waste mulch processing, in particular to a horizontal waste mulch roll cutting machine. BACKGROUND

[0002] Mulch is an important cultivation material in agricultural production in northern China. Mulch cultivation technology has promoted the development of agricultural production, but waste mulch has not been effectively recycled and resourceized, leading to serious residual film pollution problems, which the state attaches great importance to. In the prior art, patent CN116114519A and other patents provide a device for winding and recycling field mulch. The recycled and packaged mulch is large in volume, severely tangled, and wrapped with sand, soil, straw and other impurities, which brings inconvenience to the subsequent processing of recycled mulch and reduces the efficiency of residual film resource utilization. In the prior art, patent CN113878758A includes a gantry shearing mechanism for shearing waste mulch. The gantry shearing mechanism includes a conveying roller, a pushing device and a gantry hydraulic shearing machine. The pushing device pushes the mulch roll to the gantry shearing mechanism in sections, and the gantry shearing mechanism has a reciprocating lifting cutter that cuts the mulch roll in sections. This device has slow operation speed and poor continuity, which affects the operation efficiency. In addition, conventional cutting machines are mainly used for cutting metal, stone and other objects. For example, the multi-piece continuous stone cutting machine shown in patent CN108247857A includes a stone conveying belt, a saw blade mechanism and a lifting mechanism. The saw blade mechanism can continuously cut the stone conveyed by the conveying belt. However, this cutting machine cannot adapt to the characteristics of the recycled waste mulch roll. The recycled waste mulch roll has uneven winding and flexible deformation characteristics. The present application provides a cutting device for intermediate processing of the waste mulch roll to facilitate subsequent processing of the waste mulch. SUMMARY

In the scheme, the supporting piece is an L-shaped steel, and the number of the supporting pieces is two, and the two supporting pieces support the two ends of the cross rod and can limit the transverse direction of the cross rod. By arranging the supporting piece, the up-down vibration and left-right swing of the chain can be prevented, and the stability of the conveying mechanism in operation can be improved.

[0017] Further, the two ends of the intermediate partition plate and the side partition plate are in the inverted U-shaped structure, and the two edges of each partition plate are fixed on the two sides of the cross rod. By adopting the structure, the partition plate has high strength.

[0034] The cutting mechanism 3 comprises a cutting disc 31 and a first motor 32, and two cutting discs 31 are respectively opposite to the two gaps a. The cutting disc 31 is a disc, and the periphery of the disc has a blade.

[0035] During operation, the waste mulch film roll recovered from the farmland is placed between the adjacent cross bars 22 located on the upper side of the chain, the conveying mechanism 2 conveys the waste mulch film roll to the cutting mechanism 3, so that the cutting mechanism 3 can cut the waste mulch film roll conveyed by the conveying mechanism 2 in sequence, and the waste mulch film roll is cut into three sections, and the three sections of the mulch film roll are held by the middle plate 11 and the two side plates 12, and continue to move forward under the action of the middle partition plate 23 and the side partition plate 24, until the cut waste mulch film roll is separated from the holding table 1A or is taken away. When the cutting mechanism 3 performs cutting operation, the gap a and the gap b can give way to the cutting disc 31, so that the cutting disc 31 can cut the waste mulch film roll completely.

[0036] The horizontal waste mulch roll cutting machine is specially designed for the characteristics of the waste mulch roll, can transport, cut the waste mulch roll, prevent the waste mulch roll from running in the cutting process, fully meet the needs of cutting the waste mulch roll, the volume of the waste mulch roll after cutting is small, and the entanglement of the waste mulch roll and the jujube, rope is cut off, which can be more convenient for subsequent processing, and the waste mulch roll can be recycled and resource utilization.

[0037] The high-speed wear-resistant cutting disc 31 is used to cut the waste mulch roll, which can fully cut the mulch roll and the jujube, rope and other substances mixed therein, and the cutting tool will not entangle with the mulch roll, and the reliability is high.

[0038] Preferably, the cutting mechanism 3 further comprises a stand 33, the cutting disc 31 and the first motor 32 are installed in the lifting seat 34, the lifting seat 34 can slide up and down relative to the stand 33, and the drive oil cylinder 35 is arranged between the stand 33 and the lifting seat 34. By driving the drive oil cylinder 35 to operate, the height of the cutting disc 31 can be changed as needed to adjust the cutting depth of the waste mulch roll.

[0039] In one embodiment, the cutting disc 31 can perform cutting operation at a fixed height, at this time, the lowest point of the cutting disc 31 needs to be always higher than the horizontal rod 22 to prevent the two from contacting and causing damage to the cutting disc 31.

[0040] Preferably, in another embodiment, as the conveying mechanism 2 operates, the drive oil cylinder 35 can drive the cutting disc 31 to dynamically rise and fall, so that the cutting disc 31 can rise to avoid the horizontal rod 22 when crossing the horizontal rod 22, and when the cutting disc 31 performs cutting operation, the drive oil cylinder 35 drives the cutting disc 31 to fall, so that the lowest point of the cutting disc 31 is lower than the highest point of the horizontal rod 22, which can improve the cutting efficiency and cutting effect. In this embodiment, the cutting disc 31 makes regular rising and falling motion to switch between cutting operation and avoidance state. Preferably, as shown in Figure 5 The horizontal rod 22 comprises a middle rod 22a and two end rods 22b located at both ends of the middle rod 22a, and the middle rod 22a and each end rod 22b are connected by a U-shaped avoidance piece 22c, as shown in Figure 6 When the horizontal rod 22 approaches the cutting mechanism 3, the top of the avoidance piece 22c is located on the side away from the cutting mechanism 3 relative to the middle rod 22a, so that when the cutting disc 31 performs cutting operation, the pressure applied by the cutting disc 31 to the residual film roll makes the residual film roll abut against the corner between the supporting table surface 1A and the partition plate (including the middle partition plate 23 and the side partition plate 24), the cutting disc 31 can be fed between the middle rod 22a and the end rod 22b to cut the residual film roll, ensuring that the residual film roll is completely cut off.
