[0035] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] like Figures 1 to 10As shown, the embodiment of the present application also proposes an agricultural cultivation film cleaning machine, which comprises a frame 100, a film lifting shovel 200 and a film screening assembly 300, the film screening assembly 300 is located downstream of the film lifting shovel 200 in the traveling direction of the frame 100, the film screening assembly 300 comprises a plurality of film screening components 1, the plurality of film screening components 1 are arranged at intervals in the traveling direction of the frame 100, the film screening component 1 comprises a film screening roller 11 and a film cutting component 12, the film screening roller 11 extends in the width direction of the frame 100, the film cutting component 12 is installed inside the film screening roller 11, the film cutting component 12 is movable in the width direction of the frame 100 to cut the film attached to the film screening roller 11, the film cutting component 12 has a first state and a second state, in the first state, the film cutting component 12 is retracted into the film screening roller 11, and the outer surface of the film cutting component 12 is flush with the outer surface of the film screening roller 11, in the second state, the film cutting component 12 at least partially protrudes out of the film screening roller 11.

[0037] Specifically, as shown, Figure 1 the film lifting shovel 200 and the film screening assembly 300 are arranged at intervals in the front-rear direction, and the film screening assembly 300 is located at the rear end of the film lifting shovel 200, the film screening roller 11 extends in the left-right direction, the film screening roller 11 is hollow inside, and a support shaft 113 is provided in the middle of the film screening roller 11, the left and right ends of the support shaft 113 are connected to the frame 100 through bearing seats respectively, the support shaft 113 is rotatable relative to the frame 100, and the film cutting component 12 is located inside the film screening roller 11.

[0038] In the first state, the outer surface of the film cutting component 12 is flush with the outer surface of the film screening roller 11, that is, when the film cutting component 12 is in the retracted state, the outer surface of the film cutting component 12 is flush with the outer surface of the film screening roller 11.

[0039] In the second state, the outer side of the film cutting component 12 protrudes out of the film screening roller 11, that is, in the protruding state, the outer side of the film cutting component 12 protrudes out of the film screening roller 11.

[0040] When the film cutting component 12 protrudes out of the film screening roller 11, the film cutting component 12 is movable in the left-right direction, thereby cutting the film attached to the film screening roller 11, and under the joint action of the centrifugal force generated by the rotation of the film screening roller 11, the film is thrown out of the film screening roller 11, thereby reducing or avoiding the risk of the film winding around the film screening roller 11.

[0041] The agricultural cultivation film cleaning machine of the present application uses the cutting component which can move in the left-right direction to cut the film attached to the film screening roller 11, thereby reducing or avoiding the risk of the film winding around the film screening roller 11, improving the film recovery rate and work efficiency. Moreover, the cutting component has a retracted state and a protruding state, in the retracted state, the cutting component can be retracted into the film screening roller 11, thereby avoiding that the cutting component occupies too much screening space in the state that the cutting component is not in use.

[0042] In some embodiments, the screen film roller 11 is provided with a guide groove 111 extending along the width direction of the frame 100, and the film cutting component 12 is located in the guide groove 111. The film cutting component 12 includes a first support 121, a first roller 122, a second roller 123, a cutting line 124, and a first driver 125. The first roller 122 and the second roller 123 are oppositely arranged in the inner-outer direction of the screen film roller 11, and are rotatable relative to the first support 121. The cutting line 124 is wound around the outer periphery of the first roller 122 and the second roller 123. The first driver 125 is connected to the first roller 122 to drive the first roller 122 to rotate.

[0043] Specifically, as shown in Figure 2 the guide groove 111 extends along the left-right direction, and the cutting component is located in the guide groove 111 and can move left and right in the guide groove 111. The first roller 122 and the second roller 123 are oppositely arranged in the inner-outer direction. The cutting line 124 is wound around the first roller 122 and the second roller 123. When the first roller 122 and the second roller 123 rotate, the cutting line 124 can rotate around the rollers. For example, the first roller 122 and the second roller 123 are sprockets, and the cutting line 124 is a cutting chain. The first roller 122 and the second roller 123 drive the cutting line 124 to rotate. The first driver 125 can be a motor that drives the first roller 122 to rotate.

[0044] By providing the guide groove 111, the precision of the movement of the cutting component can be improved. Compared with a fixed blade, the first roller 122 and the second roller 123 drive the cutting line 124 to move cyclically and reciprocally, which can improve the efficiency and quality of the cutting of the mulch film.

[0045] In some embodiments, the film cutting component 12 further includes a heater 126 mounted on the first support 121, and the heater 126 has a heating wire connected to the second roller 123 to heat the cutting line 124 through the second roller 123.

[0046] Specifically, as shown in Figure 5 the heater 126 is mounted on the first support 121, and the heater 126 has a heating wire connected to the second roller 123. The heating wire can heat the second roller 123. The heat is transmitted to the cutting line 124 through the second roller 123 to heat the cutting line 124. The heated cutting line 124 can melt the mulch film, and the cutting effect and efficiency of the mulch film are improved by the cutting action of the cutting line 124.

[0047] It should be noted that the heater 126 can be an electric heater 126, and a temperature control switch can be used to control the opening of the heater 126.

[0048] In some embodiments, the film cutting component 12 further comprises a guide rail 127 and a sliding component 128, the guide rail 127 is installed inside the screen film roller 11 and extends along the axial direction of the screen film roller 11, one end of the sliding component 128 is connected with the guide rail 127, and the other end of the sliding component 128 is connected with the first support 121.

[0049] Specifically, as shown in Figure 4 the guide rail 127 is installed inside the screen film roller 11 and extends along the left-right direction, and the guide rail 127 is connected with the support shaft 113, the sliding component 128 is clamped in the guide rail 127 and is movable along the left-right direction, it should be noted that the sliding component 128 can be a sliding block which can be driven to slide in the left-right direction by a pneumatic cylinder, a hydraulic cylinder or a motor.

[0050] The first support 121 is hinged with the sliding component 128, it should be noted that the inner side of the first support 121 is hinged with the sliding component 128, in the first state, the first support 121 is retracted into the screen film roller 11 and is parallel with the support shaft 113, in the second state, the first support 121 is popped out of the screen film roller 11 and is arranged perpendicularly with the support shaft 113, the outer side of the first support 121 extends out of the screen film roller 11 and the cutting line 124 is exposed out of the screen film roller 11.

[0051] By setting the guide rail 127 and the sliding component 128, the moving precision of the cutting line 124 in the left-right direction can be improved, thereby improving the efficiency and quality of cutting the film.

[0052] In some embodiments, the film cutting component 12 further comprises a baffle 8 and a folding sealing plate 129, the baffle 8 is located above the screen film assembly 300 and has a preset interval with the screen film assembly 300, and the folding sealing plate 129 is connected with the first support 121 and located in the guide groove 111.

[0053] Specifically, as shown in Figure 1 and Figure 4 the baffle 8 is installed on the rack 100 and located above the screen film assembly 300, and the lower end surface of the baffle 8 has a gap with the screen film roller 11 so that the soil and the film can pass through, the rear end of the baffle 8 is bent downward to form an arc segment, one end of the folding sealing plate 129 is connected with the first support 121, and the other end of the folding sealing plate 129 is connected with the inner wall of the guide groove 111.

[0054] Optionally, a film collecting box 7 is installed at the rear end of the rack 100, and the inlet of the film collecting box 7 is open for the film to enter the film collecting box 7.

[0055] The soil and mulch can be prevented from leaking out by setting the baffle 8, the dust pollution during operation can be reduced, and the mulch can be guided to move to the mulch collecting box 7 by using the baffle 8, so that the efficiency and quality of mulch collection are improved.

[0056] The folding sealing plate 129 can seal the guide groove 111, and prevent soil or other impurities from entering the inside of the screen membrane roller 11 through the guide groove 111.

[0057] In some embodiments, the agricultural cultivation mulch cleaning machine further comprises an anti-winding assembly 2 located in the screen membrane roller 11, the anti-winding assembly 2 comprises an air outlet pipe 21 and an air source, the outlet of the air source is communicated with the air outlet pipe 21, the air outlet pipe 21 is located in the screen membrane roller 11 and extends along the axial direction of the screen membrane roller 11, and a plurality of first air outlets 112 are uniformly distributed on the surface of the screen membrane roller 11.

[0058] Specifically, as shown in Figure 3 and Figure 4 , the air outlet pipe 21 is connected with the supporting shaft 113, the air outlet pipe 21 extends along the left-right direction, the inlet of the air outlet pipe 21 is communicated with the air source, the air source can be an air compressor, the air outlet pipe 21 has a plurality of outlets, and the screen membrane roller 11 is provided with a plurality of first air outlets 112, the gas discharged from the air outlet pipe 21 is discharged from the screen membrane roller 11 through the first air outlets 112, by setting the air outlet pipe 21 and the first air outlets 112 on the screen membrane roller 11, the mulch can be blown by using the gas, the risk of mulch adhering to the screen membrane roller 11 is reduced or avoided, so that the risk of mulch winding around the screen membrane roller 11 is reduced, and the separation effect between the mulch and the soil is improved by using the gas to blow the mulch, thereby improving the quality and efficiency of mulch recovery.

[0059] In some embodiments, the first air outlet 112 has a preset included angle between the axis and the axis of the screen membrane roller 11, and the first air outlet 112 is inclined toward the side away from the mulch shovel 200.

[0060] It should be noted that the first air outlet 112 is inclined toward the rear, and the preset included angle between the first air outlet 112 and the axis of the screen membrane roller 11 is 30° to 50°, when the preset included angle is too small, the first air outlet 112 blows gas toward the adjacent screen membrane roller 11, and cannot blow the mulch upward, resulting in poor separation effect between the mulch and the soil, when the inclination angle of the first air outlet 112 is too large, the mulch has the risk of floating forward, causing the soil and the mulch to be retained between the screen membrane roller 11 and the baffle 8, affecting the screening efficiency.

[0061] By setting the first air outlet 112 inclined toward the rear, not only the mulch and the soil can be blown upward, but also the mulch can be blown backward, the conveying speed of the mulch is improved, and the screening efficiency is improved.

[0062] It should be noted that when the soil falls between the two adjacent screen film rollers 11, the first air outlet 112 on the screen film roller 11 close to the front is downward at this time, so as to further improve the soil leaving speed and accelerate the separation efficiency of the mulch film and the soil.

[0063] It should be noted that since there is a spacing distance between the two adjacent screen film rollers 11, the first air outlet 112 on the rear screen film roller 11 has little effect on the first air outlet 112 on the front screen film roller 11, in other words, the mulch film and the soil will not cause accumulation between the two adjacent screen film rollers 11.

[0064] In some embodiments, the screen film roller 11 further comprises a plurality of film breaking teeth 3, which are uniformly distributed on the outer surface of the screen film roller 11 and are arranged at intervals with the first air outlet 112. The second air outlet 31 is provided on the side away from the film starting shovel 200 of the film breaking tooth 3, and the second air outlet 31 is in communication with the inside of the screen film roller 11.

[0065] Specifically, as shown in Figures 6 to 9 , the film breaking teeth 3 are uniformly distributed on the outer wall surface of the screen film roller 11, and the plurality of film breaking teeth 3 are uniformly and spaced apart in the left-right direction. The film breaking tooth 3 is hollow and has an inlet at the bottom, the inlet is in communication with the inside of the screen film roller 11, and the second air outlet 31 is provided on the rear end face of the film breaking tooth 3. It should be noted that the gas in the inside of the screen film roller 11 enters the inside of the film breaking tooth 3 through the inlet at the bottom of the film breaking tooth 3 and is discharged through the second air outlet 31. By providing the film breaking tooth 3, the mulch film can be torn, which not only avoids the mulch film winding on the screen film roller 11, but also breaks the large mulch film into small pieces, which is beneficial to the wind blowing and improves the separation efficiency of the mulch film and the soil. The second air outlet 31 can further improve the gas flow, thereby improving the separation effect of the mulch film and the soil.

[0066] In some embodiments, the second air outlet 31 is provided with a switch plate and a traction rope 6. One end of the traction rope 6 is connected to the inner wall surface of the film breaking tooth 3, the other end of the traction rope 6 is connected to the switch plate, and the traction force of the traction rope 6 is less than the weight of the switch plate. The switch plate is arranged in the inside of the film breaking tooth 3 and extends in the inside-outside direction of the screen film roller 11, and the switch plate is movable in the inside-outside direction of the screen film roller 11 to close or open the second air outlet 31, or the number of the second air outlet 31 is multiple, the plurality of second air outlets 31 are uniformly distributed on the side end face of the film breaking tooth 3 away from the film starting shovel 200, and / or the second air outlet 31 has a preset included angle between the axis of the screen film roller 11, and the second air outlet 31 is inclined toward the side away from the film starting shovel 200.

[0067] Specifically, as shown in Figure 8 and Figure 9As shown, the switch door 5 is installed inside the film breaking tooth 3, and the size of the switch door 5 is slightly larger than the size of the second air outlet 31, the switch door 5 is tightly attached to the inner wall surface of the film breaking tooth 3, for example, a sliding groove is arranged on the inner wall surface of the film breaking tooth 3, and the switch door 5 is clamped in the sliding groove, the sliding groove limits the moving direction of the switch door 5, the switch door 5 can move along the sliding groove, the inner side of the traction rope 6 is connected with the outer surface of the screen film roller 11 or the inner wall surface of the film breaking tooth 3, and the outer side of the traction rope 6 is connected with the switch door 5, and the traction rope 6 applies an inward pulling force to the switch door 5.

[0068] It should be noted that, as Figure 7 shown, when the screen film roller 11 rotates, when the film breaking tooth 3 rotates to the upper half of the screen film roller 11, that is, the second air outlet 31 blows air upward, at this time, due to the centrifugal force generated by the switch door 5 under the action of the rotation of the screen film roller 11, and the centrifugal force is less than the combined force of the pulling force and the gravity of the traction rope 6, therefore, the switch door 5 moves inward, the second air outlet 31 opens to blow air outward, and the mulch film and the soil are separated under the action of the air force, and the mulch film is moved upward and backward under the action of the air force, and finally falls into the film collecting box 7.

[0069] As Figure 9 shown, when the film breaking tooth 3 rotates to the lower half of the screen film roller 11, that is, the second air outlet 31 blows air downward, due to the gravity of the switch door 5 being greater than the pulling force of the traction rope 6, and under the action of the centrifugal force, the switch door 5 has a tendency to move outward, the switch door 5 closes the second air outlet 31, so that only upward blowing force is generated at the intersection of the adjacent two screen film rollers 11, and the blowing force comes from the rear screen film roller 11, thereby avoiding the influence of the opposite air flow at the intersection of the adjacent two screen film rollers 11 on the efficiency of the screen film.

[0070] In some embodiments, the agricultural cultivation film cleaning machine further comprises a feeding assembly 4, which is located downstream of the film starting shovel 200 in the moving direction of the frame 100, the feeding assembly 4 comprises a second bracket 41, a feeding plate 42, an elastic member 43 and a driving component 44, the second bracket 41 is connected with the frame 100, the feeding plate 42 extends in the width direction of the frame 100, the feeding plate 42 extends into the second bracket 41 on both sides in the width direction of the frame 100, the elastic member 43 extends in the height direction of the frame 100 and is connected with the second bracket 41 and the feeding plate 42 at both ends respectively, and the driving component 44 is located at the lower end of the feeding plate 42 and is used to drive the feeding plate 42 to move up and down reciprocally.

[0071] Specifically, as Figure 10As shown, the feeding plate 42 is located behind the film forming shovel 200, and the left and right sides of the feeding plate 42 are clamped in the second support 41, the second support 41 is provided with a mounting groove, the left and right sides of the feeding plate 42 are clamped in the mounting grooves on the left and right sides respectively, the upper end of the elastic member 43 is connected with the inner wall of the second support 41, and the lower end of the elastic member 43 is connected with the feeding plate 42,

[0072] Optionally, the elastic member 43 is also arranged at the lower end of the feeding plate 42, and the upper end of the lower elastic member 43 is connected with the feeding plate 42, and the lower end of the lower elastic member 43 is connected with the inner wall of the second support 41.

[0073] Optionally, a folding sealing plate 129 can be arranged between the feeding plate 42 and the mounting groove, and the mounting groove is sealed by the folding sealing plate 129 to avoid foreign matters from entering the inside of the mounting groove.

[0074] The driving component 44 includes a driving shaft 441 and a plurality of cams 442, the driving shaft 441 is located below the feeding plate 42, the plurality of cams 442 are sleeved on the driving shaft 441, and the outer surface of the cam 442 is in contact with the lower end of the feeding plate 42, when the driving shaft 441 rotates, the cam 442 drives the feeding plate 42 to move up and down, when the feeding plate 42 moves up and down, not only can the mulch film and the soil be shaken, but also the soil and the mulch mixture entering the screen film roller 11 are more evenly distributed, the quality and efficiency of the screen film are improved, and part of the soil is crushed to avoid blockage caused by large pieces of soil.
