Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, in particular to a film slitting and rolling device for a tobacco film peeling and ridging machine. Background Art

[0002] Tobacco mulching planting technology is a widely used agricultural production and income increasing technology in my country today. This technology has many advantages such as water saving and drought resistance, temperature increase and moisture retention, but the mulch film needs to be recovered in time during the flue-cured tobacco seedling stage to facilitate the growth of crops. The film peeling machine in the prior art usually uses the film lifting teeth on the film lifting roller shaft to lift the mulch film, and then rolls the film. For example, the Chinese invention patent with the authorization announcement number CN102726260B discloses a seedling film peeling machine, and its film peeling mechanism includes a bracket welded by a left support frame, a right support frame and a crossbeam, and the stripping plate is fixed to the left support frame and the right support frame by bolts, and the stripping plate is provided with a plurality of side-by-side stripping guide grooves for the film lifting teeth to pass through, and the stripping guide groove is provided with an inlet and an outlet, and the film lifting roller shaft spans the left support frame and the right support frame, and the film lifting teeth are welded on the film lifting roller shaft. Another example is a Chinese invention patent with the authorization announcement number CN110178611B, which discloses a sugarcane film peeling machine, whose film rolling wheel includes two film rolling assemblies symmetrically arranged on the film rolling shaft, and the film rolling assemblies include baffles I, baffles II and multiple cross bars, and the cross bars are provided with a needle group for piercing and lifting the ground film. However, in the actual rolling process, it was found that due to the uneven force on the unfolded film, it is easy to tear and cause the machine to stop, and using the above-mentioned film lifting teeth or needles to pierce and lift the ground film is more likely to cause uneven force on the ground film and cause tearing, so how to increase the tensile strength of the film to avoid the occurrence of film breakage is a problem that needs to be considered.

Figure 1 As shown, the front end of the vehicle body 1 is provided with a film cutting device 2, and when the present invention is working, as shown in FIG. Fig. 9 As shown, the ground film is divided into two by the film cutting device 2 and then wound on the corresponding film roll drum 313 respectively, and the wheels 105 on both sides of the vehicle body 1 respectively transmit torque through the corresponding first transmission assembly 104 to drive the corresponding first horizontal axis 310 to rotate, and the first horizontal axis 310 drives the vertical axis 309 on the corresponding side to rotate through the gear set A, as shown in FIG. Fig.11 As shown, the vertical shaft 309 drives the mounting frame 317 to twist so that the ground film is twisted into a rope-like shape. At the same time, the fourth bevel gear 304 moves along the circumferential direction of the third bevel gear 303 as the mounting frame 317 twists, and the fourth bevel gear 304 rotates itself to drive the second horizontal shaft 311 to rotate. The second horizontal shaft 311 drives the film winding drum 313 to rotate through the second transmission assembly to realize the film winding operation. The present invention increases the tensile strength of the film body by cutting the film body and twisting it into a rope-like shape and winding it around the film winding drum 313, thereby avoiding the occurrence of film breakage.

[0034] like Figures 3-4 As shown, in this embodiment, the gear set A includes a first bevel gear 301 and a second bevel gear 302 that are meshed with each other, wherein the first bevel gear 301 is arranged on the first horizontal axis 310, and the second bevel gear 302 is arranged on the vertical axis 309, and the second transmission assembly includes a driving pulley 314, a driven pulley 315 and a synchronous belt 316, wherein the driving pulley 314 is installed on the second horizontal axis 311, and the driven pulley 315 is installed on the rotating shaft 312, and the driving pulley 314 and the driven pulley 315 are connected by the synchronous belt 316.

[0035] like Figures 3-4As shown, a bearing seat 307 is provided on the upper side of the fixed beam 305, a sleeve 308 is fixed on the lower side of the fixed beam 305 and is sleeved on the vertical shaft 309, and the third bevel gear 303 is fixed to the lower end of the sleeve 308, and bearings are provided in the bearing seat 307 and the sleeve 308 for positioning and supporting the rotation of the vertical shaft 309.

[0036] like Figures 3-4 As shown, the film roll drum 313 is provided with a roller front plate 318 on one side and a roller rear plate 319 on the other side. The mounting frame 317 is provided with a fastening element 320 on the side away from the second transmission assembly. The fastening element 320 can be a bolt or a push-pull buckle. For example, when a bolt is used, when the film roll drum 313 is fully rolled up with ground film, the fastening element 320 is first disassembled, and then the roller front plate 318 is separated from the film roll drum 313 body to remove the film roll. This is a well-known technology in the art. Figure 3 As shown, a torque limiter 321 can be provided on the rotating shaft 312 of the film roll drum 313 as required. When the film tension reaches the rated value, the torque limiter 321 will be triggered to convert the internal static friction into dynamic friction to avoid the film from breaking. The torque limiter 321 is a well-known technology in the art and is a commercially available product.

[0037] like Figure 1 As shown, the vehicle body 1 includes a crossbeam 102 and a side beam 103, and the crossbeam 102 and the side beam 103 are each provided with a plurality of adjustment holes, wherein the mounting rods on various agricultural implements can be respectively installed in the corresponding adjustment holes on the corresponding crossbeam 102 as required, so that the lateral adjustment of the agricultural implements can be achieved, and the two ends of each crossbeam 102 are respectively installed in the corresponding adjustment holes on the corresponding side beam 103, so that the longitudinal adjustment of the crossbeam 102 can be achieved, that is, the longitudinal adjustment of the agricultural implements can be achieved. In addition, in this embodiment, the first transmission components 104 on both sides of the vehicle body 1 are belt transmission components, wherein the driving pulley is connected to the wheel axle of the wheel 105, and the driven pulley is connected to the first transverse axis 310, and mounting brackets are provided on both sides of the vehicle body 1, and the first transmission component 104 is installed on the corresponding mounting brackets.

[0038] like Figure 2 As shown, in one embodiment of the present invention, the film cutting device 2 includes a film cutting adjustment seat 203, a film cutting rod 202 and a film cutting knife 201, wherein the film cutting adjustment seat 203 is fixed to the corresponding adjustment hole on the corresponding cross beam 102 of the vehicle body 1 by bolts, and the position of the film cutting adjustment seat 203 can be adjusted as needed, and a bent film cutting rod 202 is provided on the lower side of the film cutting adjustment seat 203, and a film cutting knife 201 is provided at the free end of the film cutting rod 202, and the ground film is divided into two by the film cutting knife 201, and then the two parts of the ground film are fixed to the corresponding film roll 313 respectively. Figure 4 and Fig.10As shown, the bending angle of the film cutting rod 202 needs to be specially designed to ensure that the ground film is input from the lower side of the film roll drum 313 and the angle α between the ground film input direction and the horizontal direction is large enough, so that when the mounting frame 317 is twisted, the baffles on both sides of the film roll drum 313 will not scrape the ground film.

[0039] like Figures 5 to 7 As shown, in another embodiment of the present invention, the film cutting device 2 is provided with film raising adjustment components 6 on both sides, and the film raising adjustment components 6 are provided with an upper stop rod 603 and a lower stop rod 604 with adjustable upper and lower spacings, and the film raising adjustment components 6 are provided with limit blocks 602 with adjustable left and right spacings on both sides, and the limit blocks 602 are sleeved on the upper stop rod 603 and the lower stop rod 604, and the ground film passes through the gap opening formed by the upper stop rod 603, the lower stop rod 604 and the limit blocks 602 on both sides and then is wound on the film roll drum 313, as shown in FIG. Fig. 9 As shown, the present invention utilizes an upper baffle 603, a lower baffle 604 and limit blocks 602 on both sides to compress the separated ground film to increase the tensile strength of the ground film after it is peeled off, and then twists it into a rope, and the upper baffle 603 and the lower baffle 604 can block the soil scraped onto the surface of the ground film to avoid the influence of the soil, and the spacing between the upper baffle 603 and the lower baffle 604 and the spacing between the limit blocks 602 on both sides can be adjusted according to actual needs to compress the ground film space to form shapes of different thicknesses, thereby adjusting its tensile strength, and in addition, the limit block 602 adopts a flexible block structure (rubber block, etc.) to avoid the edge cutting the ground film and causing it to break.

[0040] like Figure 6 As shown, the film-raising adjustment component 6 includes a mouth-shaped adjustment mounting seat 601, and cam grooves are provided on both sides of the inner wall of the adjustment mounting seat 601. Figure 8 As shown, the cam groove is provided with an upper eccentric cam 6031 and a lower eccentric cam 6041 which abut against each other, and the two ends of the upper blocking rod 603 are respectively connected to the upper eccentric cam 6031 on the corresponding side, and the two ends of the lower blocking rod 604 are respectively connected to the lower eccentric cam 6041 on the corresponding side. Figure 6 As shown, a gap adjustment bolt 6032 is provided on the side wall of the adjustment mounting seat 601, and the gap adjustment bolt 6032 is connected to the upper eccentric cam 6031 on the corresponding side. When adjusting, the operator screws the gap adjustment bolt 6032 to drive the upper eccentric cam 6031 to rotate. Figure 8 As shown, the upper eccentric cam 6031 rotates and squeezes the lower eccentric cam 6041 to rotate, thereby changing the gap between the upper blocking rod 603 and the lower blocking rod 604. Figure 6As shown, the upper eccentric cam 6031 and the lower eccentric cam 6041 on the side away from the gap adjustment bolt 6032 are driven wheels and rotate synchronously to ensure that the upper and lower ends of the upper blocking rod 603 and the lower blocking rod 604 rise and fall synchronously. In addition, since the adjustment range of the upper and lower blocking rods is relatively small, although a small distance of displacement will be generated when the gap adjustment bolt 6032 is screwed, the upper eccentric cam 6031 and the lower eccentric cam 6041 will not be separated. As long as the upper eccentric cam 6031 and the lower eccentric cam 6041 have a suitable thickness and the cam groove has a suitable depth, the upper and lower blocking rods can move in a very small range in the axial direction, which will not affect their functions of radially limiting the position of the ground film and blocking the soil.

[0041] like Figure 7 As shown, the limit block 602 is provided with a through hole 6022 for the upper stop rod 603 and the lower stop rod 604 to pass through, and the through hole 6022 is left with an appropriate clearance margin to ensure the spacing adjustment of the upper stop rod 603 and the lower stop rod 604. Figure 6 As shown, both sides of the adjustment mounting seat 601 are provided with limit adjustment bolts 6021, and the limit blocks 602 are respectively connected to the limit adjustment bolts 6021 on the corresponding sides. By screwing the limit adjustment bolts 6021, the limit blocks 602 can be driven to change the spacing.

[0042] like Figures 5 to 7 As shown, the film cutting device 2 of this embodiment includes a film cutting adjustment seat 203, a height adjustment rod 4, a mounting seat 5, a film lifting adjustment component 6, a spacing adjustment rod 606, a mounting rod 8 and a film cutting knife 201, wherein the film cutting adjustment seat 203 is also adjustably arranged on the corresponding crossbeam 102 of the vehicle body 1, the upper end of the height adjustment rod 4 is fixedly connected to the film cutting adjustment seat 203, and the lower end is fixedly connected to the mounting seat 5, both sides of the mounting seat 5 are provided with spacing adjustment rods 606 connected to the film lifting adjustment component 6 on the corresponding side, the upper side of the mounting rod 8 is provided with a height adjustment part 7 connected to the mounting seat 5, and the free end of the mounting rod 8 is provided with a film cutting knife 201, as shown in FIG. Fig. 9 As shown, when the present embodiment is working, the film cutting knife 201 divides the ground film into two parts, and the two parts of the ground film respectively pass through the film-lifting adjustment components 6 on the corresponding sides and are wound around the corresponding film rolling drum 313. In addition, the film-lifting adjustment component 6 can also play a role in peeling off the film. The length of the height adjustment rod 4 is adjustable to change the height of the lower mounting seat 5 according to the need of peeling off the film, and the length of the height adjustment part 7 of the mounting rod 8 is adjustable to change the height of the film cutting knife 201 as needed. The height change of the mounting seat 5 and the film cutting knife 201 can adjust the peeling angle, cutting height and Figure 4 The angle α and other parameters shown in the figure, the length of the spacing adjustment rod 606 is adjustable to change the distance between the film adjustment components 6 on both sides as needed.

[0043] like Figure 5As shown, in this embodiment, the height adjustment rod 4, the spacing adjustment rod 606 and the height adjustment part 7 have the same structure, and all include an upper rod 401 and a lower rod 402 that are mounted together. The upper rod 401 and the lower rod 402 are each provided with a plurality of adjustment screw holes. When the length position of the upper rod 401 and the lower rod 402 is determined, they are fixedly connected by being installed in the corresponding adjustment screw holes through bolts.

[0044] Furthermore, Figures 5 to 7 As shown, in this embodiment, a pressure sensor 605 can be provided on the limit block 602 to control the equal division of the two sides of the ground film. Specifically, when the gap openings formed by the upper blocking rod 603, the lower blocking rod 604 and the limit block 602 in the film adjustment components 6 on both sides are the same, if the two sides of the ground film are divided equally, the ground film squeezed in the gap opening should exert equal pressure on the pressure sensor 605, thereby determining that the film cutting knife 201 is moving along the center line of the ground film. If the pressure difference detected by the pressure sensors 605 on both sides exceeds the set value, it means The widths of the mulch films on both sides after segmentation are different, which results in the mulch film width on one side passing through the gap opening being too small, resulting in low pressure, and the mulch film width on the other side passing through the gap opening being too large, resulting in excessive pressure, that is, the film cutting knife 201 deviates from the center line of the mulch film, and the mulch film with a smaller width is more likely to break. At this time, the control system can issue an alarm to prompt the operator, and the operator can stop the machine for adjustment. In this embodiment, the upper end of the height adjustment part 7 is threadedly connected to the mounting seat 5, and the operator can rotate the mounting rod 8 to adjust its angle so that the film cutting knife 201 is placed back at the center line of the mulch film.

[0045] The working principle of the present invention is:

[0046] When the present invention is working, the ground film is cut into two by the film cutting device 2 and then wound on the corresponding film roll drum 313 respectively, and the wheels 105 on both sides of the vehicle body 1 transmit torque through the first transmission assembly 104 to drive the corresponding first horizontal axis 310 to rotate, and the first horizontal axis 310 drives the vertical axis 309 to rotate through the gear set A. Fig.11 As shown, the vertical shaft 309 drives the mounting frame 317 on the corresponding side to twist, and then drives the film roll drum 313 to twist so that the ground film is twisted into a rope-like shape, and the fourth bevel gear 304 revolves along the circumferential direction of the third bevel gear 303 with the mounting frame 317, and at the same time, it also rotates itself and drives the second horizontal shaft 311 to rotate, and the second horizontal shaft 311 drives the film roll drum 313 to rotate around its own axial direction through the second transmission assembly to realize the film rolling operation. The present invention increases the tensile strength of the film body and avoids the occurrence of film breakage by cutting the film body and twisting it into a rope-like shape and winding it around the corresponding film roll drum 313.

[0047] In addition, Fig. 9As shown, the present invention can be provided with film-lifting adjusting components 6 on both sides of the film cutting device 2 as needed. After the ground film is divided into two by the film cutting knife 201, each part passes through the gap opening formed by the upper blocking rod 603, the lower blocking rod 604 and the limit blocks 602 on the corresponding side and then is wound on the film rolling drum 313. The gap opening squeezes the ground film into a rope-like shape to improve the tensile strength, and the spacing between the upper blocking rod 603 and the lower blocking rod 604 and the spacing between the limit blocks 602 on both sides can be adjusted according to actual needs to compress the ground film space to form ropes of different thicknesses, thereby adjusting its tensile strength, which is more flexible to use. The upper blocking rod 603 and the lower blocking rod 604 can also block the soil attached to the upper and lower surfaces of the ground film to prevent it from affecting the tensile strength of the ground film. The film-lifting adjusting component 6 can also play a role in removing the film, and as shown Figure 5 As shown, the film cutting device 2 can be provided with structures such as a height adjustment rod 4, a spacing adjustment rod 606, and a mounting rod 8, and a height adjustment portion 7 is provided at the upper end of the mounting rod 8, so that the film peeling angle between the ground film and the ground can be changed as needed.
