Description

Technical Field

[0001] The invention relates to the technical field of agricultural waste mulch film processing, in particular to a horizontal waste mulch film roll cutting machine. Background Art

[0002] Ground film is an important cultivation material in agricultural production in northern my country. Ground film covering cultivation technology has promoted the development of agricultural production, but the waste ground film has not been effectively recycled and resourced, resulting in serious residual film pollution problems. The country attaches great importance to this. In the prior art, patents such as CN116114519A provide a device for rolling and recycling field ground film. After recycling and packaging, the ground film is large in volume, seriously entangled, and contains various impurities such as gravel, soil, and straw, which brings inconvenience to the subsequent treatment of the recycled ground film and reduces the efficiency of residual film resource utilization. In the prior art, patent CN113878758A contains a gantry shearing mechanism for shearing waste ground film. The gantry shearing mechanism includes a conveying roller, a pushing device, and a gantry hydraulic shearing machine. The pushing device pushes the ground film roll to the gantry shearing mechanism section by section. The gantry shearing mechanism has a reciprocating lifting and lowering guillotine to cut the ground film roll section by section. The operation speed of this equipment is slow and the continuity is poor, which affects the operation efficiency. In addition, conventional cutting machines are mainly used for cutting metals, stones and other objects, such as the multi-blade continuous stone cutting machine shown in patent CN108247857A, which includes a stone conveyor belt, a saw blade mechanism, and a lifting mechanism. The saw blade mechanism can continuously cut the stone conveyed by the conveyor belt, but the cutting machine is difficult to adapt to the characteristics of the recycled waste ground film rolls. The waste ground film rolls have the characteristics of uneven winding, flexibility and easy deformation. The present invention aims at the technical difficulties that the technical method for cutting the waste ground film into rolls after recycling and packaging is missing, and the existing crushing and recycling equipment cannot be used directly. A cutting device for intermediate processing of the waste ground film rolls is provided to facilitate the subsequent processing of the waste ground film. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a horizontal waste mulch film roll cutting machine that can cut waste mulch film rolls into pieces for easy subsequent processing.

[0004] Technical solution: To achieve the above-mentioned purpose, the horizontal waste mulch film roll cutting machine of the present invention comprises a machine base, a conveying mechanism and a cutting mechanism; the conveying mechanism can convey the waste mulch film roll to the cutting mechanism;

[0005] The upper side of the machine base has a three-section support table, which includes a middle plate and two side plates located on the left and right sides of the middle plate, and there is a gap between the middle plate and each of the side plates, that is, there are gaps on both sides of the middle plate;

[0006] The conveying mechanism has two groups of chains, and the two groups of chains are respectively located at two gap positions on both sides of the middle plate; the conveying mechanism also includes a plurality of cross bars dispersedly fixed on the chains, each of which is fixed with a middle partition and two side partitions respectively located on both sides of the middle partition, and there is a gap between the middle partition and each of the side partitions;

[0007] The cross bar located at the upper chain segment of the chain is supported by the supporting table, and the supporting table can assist in supporting the cut waste mulch roll.

[0008] The cutting mechanism comprises a cutting disc and a first motor, wherein the two cutting discs face the two gaps respectively. The cutting disc is in a disc shape and has a cutting edge around it.

[0009] During operation, the waste mulch rolls recovered from the farmland are placed between the adjacent cross bars located on the upper chain segment, and the conveying mechanism conveys the waste mulch rolls to the cutting mechanism. Each part of the waste mulch roll is pushed forward synchronously by the partition, so that the cutting mechanism can cut the waste mulch rolls conveyed by the conveying mechanism in sequence. The waste mulch rolls are cut into three sections, which are supported by the middle plate and two side plates respectively, and continue to move forward under the action of the middle partition and the side partition until the cut waste mulch rolls are separated from the supporting table or taken away. When the cutting mechanism performs the cutting operation, the gaps and intervals can give way to the cutting disc, so that the cutting disc can fully cut the waste mulch rolls.

[0010] Furthermore, the cutting mechanism also includes a stand, the cutting disc and the first motor are both installed in a lifting seat, the lifting seat can slide and rise relative to the stand, and a driving cylinder is arranged between the stand and the lifting seat.

[0011] In one solution, the cutting disc can perform cutting operations at a fixed height. In this case, the lowest point of the cutting disc needs to be always higher than the cross bar to prevent the two from contacting each other and causing damage to the cutting disc.

[0012] Preferably, in another solution, as the conveying mechanism operates, the driving cylinder can drive the cutting disc to rise and fall dynamically, so that when the cutting disc crosses the crossbar, it can rise to avoid the crossbar. When the cutting disc performs a cutting operation, the driving cylinder drives the cutting disc to fall, so that the lowest point of the cutting disc is lower than the highest point of the crossbar, thereby improving the cutting efficiency and the cutting effect. In this solution, the cutting disc performs regular lifting and lowering movements to switch back and forth between the cutting operation and the avoidance state.

[0013] Furthermore, the stand is composed of four vertical square tubes, and the lifting seat is a sleeve composed of plates surrounding the four sides of the stand, and four angle steels in contact with the four square tubes are fixed at the four corners of the sleeve; a rotating shaft connected to the cutting disc is installed on the lifting seat; the first motor is connected to the rotating shaft through a transmission mechanism, and the transmission mechanism can be a belt transmission mechanism, a chain transmission mechanism, a gear set, etc. The above-mentioned driving cylinder is placed between the four square tubes, and the two ends of the driving cylinder are respectively connected to the top of the stand and the connecting ears on the inner side of the lifting seat, so that not only can the driving cylinder be hidden and installed, but also the lifting seat can be lifted and lowered smoothly without jamming.

[0014] The rotating shaft passes through the hollow part of the lifting seat, and a pair of opposite side plates of the lifting seat are both equipped with bearing seats for supporting the rotating shaft, and the two ends of the rotating shaft are respectively connected to the transmission mechanism and the cutting disc. It can be seen that the use of the above-mentioned sleeve structure of the lifting seat composed of four side plates, combined with two bearing seats, can provide sufficient support for the rotating shaft, can fully resist the reaction force applied by the cutting disc during cutting, and has high cutting stability.

[0015] Furthermore, the two groups of upright frames are arranged symmetrically on the left and right, with a crossbeam connecting the tops of the two. The crossbeam and the left and right upright frames form a gate-shaped structure to maintain the stability of the structure; each of the upright frames is equipped with a corresponding

[0016] Furthermore, the base has a supporting member for supporting the crossbar on the lower chain segment of the chain. In this solution, the supporting member is an L-shaped steel, and the number of the supporting members is two groups on the left and right, which respectively support the two ends of the crossbar and can limit the lateral direction of the crossbar. By providing the above-mentioned supporting member, it is possible to prevent the chain from vibrating up and down and shaking left and right, thereby improving the stability of the conveying mechanism.

[0017] Furthermore, both ends of the middle partition and the side partition are inverted U-shaped structures, and the two edges of each partition are fixed on the two sides of the cross bar. With this structure, the partition has a higher strength.

[0018] Beneficial effects: The horizontal waste mulch film cutting machine of the present invention has the following beneficial effects:

[0019] (1) The horizontal waste ground film roll cutting machine of the present invention is specially designed according to the characteristics of waste ground film rolls. It can carry out roll transportation and cutting of waste ground film rolls. The flexible and deformable characteristics of waste ground film rolls are adapted to during transportation. The waste ground film rolls can be prevented from shifting during cutting and the uneven winding and flexible characteristics of waste ground film rolls can be adapted to. The needs for cutting waste ground film rolls are fully met. The waste ground film rolls after cutting are small in size and the entanglement of the gypsum and ropes therein is cut off, which makes subsequent processing more convenient and facilitates the recycling and resource utilization of waste ground film rolls.

[0020] (2) The waste mulch roll is cut by a high-speed wear-resistant cutting disc, which can fully cut off the mulch roll and the materials such as platycodon and rope mixed therein, and the cutter will not get entangled with the mulch roll during the cutting process, so the reliability is high.

[0021] (3) By driving the driving cylinder to operate, the height of the cutting disc can be changed as needed, thereby achieving the adjustment of the cutting depth of the waste mulch roll as needed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 3 The horizontal waste mulch film roll cutting machine shown comprises a machine base 1 , a conveying mechanism 2 and a cutting mechanism 3 ; the conveying mechanism 2 can convey the waste mulch film roll to the cutting mechanism 3 .

[0031] The upper side of the machine base 1 has a three-section supporting table 1A, which includes a middle plate 11 and two side plates 12 located on the left and right sides of the middle plate 11. There is a gap a between the middle plate 11 and each of the side plates 12, that is, there is a gap a on both sides of the middle plate 11.

[0032] The conveying mechanism 2 has two groups of chains 21, and the two groups of chains 21 are respectively located at two gap positions on both sides of the middle plate 11; the conveying mechanism 2 also includes a plurality of cross bars 22 dispersedly fixed on the chains 21, and each of the cross bars 22 is fixed with a middle partition 23 and two side partitions 24 respectively located on both sides of the middle partition 23, and there is a gap b between the middle partition 23 and each of the side partitions 24.

[0033] The cross bar 22 located at the upper chain segment of the chain 21 is supported by the supporting table 1A, and the supporting table 1A can assist in supporting the cut waste mulch roll.

[0034] The cutting mechanism 3 comprises a cutting disc 31 and a first motor 32. The two cutting discs 31 are respectively facing the two gaps a. The cutting disc 31 is disc-shaped and has a cutting edge around it.

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

[0036] The horizontal waste ground film roll dividing and cutting machine of the present invention is specially designed according to the characteristics of waste ground film rolls. It can divide and transport and cut waste ground film rolls and prevent the waste ground film rolls from moving during the cutting process, fully meeting the needs of cutting waste ground film rolls. The waste ground film rolls after cutting are small in size and the entanglement of the gypsum and ropes therein is cut off, which can be more convenient for subsequent processing and convenient for recycling and resource utilization of waste ground film rolls.

[0037] The waste mulch roll is cut by a high-speed wear-resistant cutting disc 31, which can fully cut off the mulch roll and materials such as platycodon, rope, etc. mixed therein, and the cutter will not be entangled with the mulch roll during the cutting process, and the reliability is high.

[0038] Preferably, the cutting mechanism 3 further includes a stand 33, the cutting disc 31 and the first motor 32 are both installed in a lifting seat 34, the lifting seat 34 can slide and rise relative to the stand 33, and a driving cylinder 35 is provided between the stand 33 and the lifting seat 34. By driving the driving cylinder 35 to operate, the height of the cutting disc 31 can be changed as needed, so as to adjust the cutting depth of the waste film roll as needed.

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

[0040] Preferably, in another embodiment, as the conveying mechanism 2 operates, the driving cylinder 35 can drive the cutting disc 31 to dynamically rise and fall, so that when the cutting disc 31 crosses the cross bar 22, it can rise to avoid the cross bar 22. When the cutting disc 31 performs a cutting operation, the driving cylinder 35 drives the cutting disc 31 to descend, so that the lowest point of the cutting disc 31 is lower than the highest point of the cross bar 22, thereby improving the cutting efficiency and the cutting effect. In this embodiment, the cutting disc 31 performs regular lifting and lowering movements to switch back and forth between the cutting operation and the avoidance state. Preferably, as Figure 5 As shown, the crossbar 22 includes a middle bar 22a and two end bars 22b located at both ends of the middle bar 22a. The middle bar 22a and each end bar 22b are connected by a U-shaped avoidance member 22c. Figure 6 As shown, when the cross bar 22 approaches the cutting mechanism 3, the top of the avoidance member 22c is located on the side away from the cutting mechanism 3 relative to the intermediate rod 22a. In this way, when the cutting operation is performed, when the pressure exerted by the cutting disk 31 on the residual film roll makes the residual film roll rest against the corner between the supporting table 1A and the partition (including the middle partition 23 and the side partition 24), the cutting disk 31 can be fed between the intermediate rod 22a and the end rod 22b to cut through the residual film roll, thereby ensuring that the residual film roll is completely cut off.

[0041] Preferably, the stand 33 is composed of four vertical square tubes 33a, and the lifting seat 34 is a sleeve body composed of plates surrounding the four sides of the stand 33, such as Figure 4 As shown, four angle steels 34a in contact with four square tubes are fixed at the four corners of the sleeve respectively; a rotating shaft 36 connected to the cutting disc 31 is installed on the lifting seat 34; the first motor 32 is connected to the rotating shaft 36 through a transmission mechanism 37, and the transmission mechanism 37 can be in the form of a belt transmission mechanism, a chain transmission mechanism, a gear set, etc. The above-mentioned driving cylinder 35 is placed between the four square tubes 33a, and the two ends of the driving cylinder are respectively connected to the top of the stand 33 and the connecting ear 34b located on the inner side of the lifting seat 34. In this way, not only can the driving cylinder 35 be hidden and installed, but also the lifting seat 34 can be lifted and lowered smoothly without jamming.

[0042] The rotating shaft 36 passes through the hollow part of the lifting seat 34, and a pair of opposite side plates of the lifting seat 34 are both installed with bearing seats 39 for supporting the rotating shaft 36. The two ends of the rotating shaft 36 are respectively connected to the transmission mechanism 37 and the cutting disc 31. It can be seen that the sleeve structure of the lifting seat 34 composed of four side plates combined with the two bearing seats 39 can provide sufficient support for the rotating shaft 36, which can fully resist the reaction force applied by the cutting disc 31 during cutting, and the cutting stability is high.

[0043] Preferably, the two groups of upright frames 33 are arranged symmetrically on the left and right, with a crossbeam 38 connecting the tops of the two. The crossbeam 38 and the left and right upright frames 33 form a gate-shaped structure to maintain the stability of the structure; each of the upright frames 33 is equipped with a corresponding

[0044] Preferably, the base 1 has a supporting member 13 for supporting the cross bar 22 located on the lower segment of the chain 21. In this embodiment, the supporting member 13 is an L-shaped steel, and the number of the supporting members 13 is two groups on the left and right, which respectively support the two ends of the cross bar 22 and can limit the lateral direction of the cross bar 22. By providing the above-mentioned supporting member 13, it is possible to prevent the chain from vibrating up and down and shaking left and right, thereby improving the stability of the operation of the conveying mechanism 2.

[0045] Preferably, both ends of the middle partition 23 and the side partition 24 are inverted U-shaped structures, and the two edges of each partition are respectively fixed on both sides of the cross bar 22. With this structure, the partition has a higher strength.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
