Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to a film covering frame, film covering device, and film covering method. Background Technology

[0002] Agricultural operations often involve uneven ground conditions, slopes, and potholes, especially in mountainous and hilly areas. Existing mulching machines are prone to tilting in such environments, leading to poor mulching and soil covering effects, and in severe cases, tipping over, posing safety hazards. Furthermore, if the pressing roller encounters a protrusion (such as a rock or hard clod of soil) during operation, it can lift the covering roller upwards or even remove it from the ground, resulting in poor soil covering or even preventing soil covering altogether. Summary of the Invention

[0003] To address the above problems, this invention designs a laminating frame, including a frame and a laminating mechanism connected to the frame.

[0004] The pressing mechanism includes support frames arranged opposite each other.

[0005] At least one of the support frames is connected to a pressing and adjusting assembly, and the support frame is connected to the frame through the pressing and adjusting assembly;

[0006] The support frame is connected to a pressing assembly, which includes a pressing wheel and a covering wheel. The pressing wheel is connected to the support frame through a pressing adjustment assembly.

[0007] Compared with the prior art, the beneficial effects of the present invention are as follows: By connecting the support frame and the machine frame through the pressing and adjusting component, the pressing and adjusting components on both sides can be adjusted independently, so that the pressing rollers and covering rollers on both sides can adapt to changes in the ground, preventing the mulching machine from tilting or overturning in mountainous, hilly and other working areas, which is conducive to improving the mulching effect, soil covering effect and safety; when the pressing roller encounters a protrusion during operation, the pressing and adjusting component can adjust the height of the pressing roller independently to prevent the pressing roller from driving the covering roller upward, which is conducive to further improving the soil covering effect of the covering roller.

[0008] Preferably, the pressing and adjusting assembly includes a connector that is connected to the support frame.

[0009] The support frame is directly or movably connected to the frame via a connector, and the connector is connected to the frame via an elastic element; more preferably, the support frame is rotatably or slidably connected to the frame.

[0010] The advantages of this preferred solution are as follows: the support frame is movably connected to the machine frame, and the height of the pressing roller and the covering roller can be adjusted by rotating the support frame to better adapt to the ground terrain; the support frames on both sides are independently suspended and do not interfere with each other, which can prevent the film covering machine from tilting or tipping over; the connecting parts and elastic parts can control the rotation range of the support frame and improve the stability of the support frame; the elastic parts can not only provide cushioning and shock absorption for the support frame, but also promote the return of the support frame through the pre-tightening force of the elastic parts, while increasing the pressure applied by the pressing roller to the ground and improving the film covering effect.

[0011] Preferably, the connector includes a plurality of sleeves, and a first connecting rod is connected to the sleeves. The first connecting rod is connected to the frame through an elastic element.

[0012] The support frame passes through the sleeve.

[0013] When the support frame is movably connected to the frame via a connector, the sleeve is rotatably connected to the frame.

[0014] Preferably, the connector includes a sleeve, and the frame is provided with an outer sleeve. The sleeve passes through the outer sleeve and is rotatably connected to the outer sleeve. More preferably, the support frame is slidably connected to the sleeve. Even more preferably, at least one of the sleeves is provided with a locking mechanism. More preferably, the sleeve is provided with a through hole, and the locking mechanism includes a locking bolt, which passes through the through hole and is threadedly connected to the through hole.

[0015] The advantages of this preferred solution are as follows: the support frame can be directly rotatably connected to the machine frame, or the support frame can be rotatably connected to the machine frame through a sleeve. When the support frame is rotatably connected to the machine frame through a sleeve, it can not only rotate relative to the machine frame, but also rotate relative to the sleeve. Then, the support frame and the sleeve are fixed by a locking mechanism, thereby adjusting the height of the pressing roller and the covering roller, and adjusting the soil covering depth to adapt to different ridge heights and crop operating environments. The support frame slides relative to the outer sleeve, which can adjust the lateral distance between the support frames on both sides, so that the covering frame can adapt to different width operating environments.

[0016] Preferably, the frame is provided with a connecting seat, and the first connecting rod is connected to the connecting seat through an elastic element.

[0017] More preferably, the connector includes a sleeve, both ends of which are connected to a first connecting rod, and the first connecting rod is connected through a first connecting plate;

[0018] Alternatively, the connector may include at least two sleeves, with the first connecting rods on any two sleeves connected by a first connecting plate.

[0019] The advantages of this preferred solution are: first connecting rods are provided on both sides of the connecting seat, and the first connecting rods on both sides are connected by a first connecting plate, which can improve the stability of the pressure adjustment component.

[0020] Preferably, the support frame includes a first crossbeam and a second crossbeam connected to the first crossbeam, the first crossbeam being directly or movably connected to the frame via a connector; more preferably, a pressure film adjusting assembly is connected to the second crossbeam, and the pressure film wheel is connected to the second crossbeam via the pressure film adjusting assembly; even more preferably, the first crossbeam is perpendicular to the second crossbeam.

[0021] The advantages of this preferred solution are: by setting the first and second crossbeams, the support frame can rotate relative to the machine frame without affecting the travel direction of the pressing roller. Simultaneously, the support frame can be folded upwards with the first crossbeam as the axis of rotation, facilitating storage.

[0022] Preferably, the pressure film adjusting assembly includes a second connecting plate, which is rotatably connected to the axle of the pressure film wheel and rotatably connected to the second crossbeam.

[0023] The beneficial effect of this preferred solution is that when the pressing wheel encounters a protrusion during operation, the pressing wheel rotates relative to the second crossbeam under the drive of the second connecting plate, thereby independently adjusting the height of the pressing wheel and preventing the pressing wheel from driving the covering wheel upward.

[0024] Preferably, the second crossbeam is provided with a mounting component, and the second connecting plate is rotatably connected to the mounting component; preferably, the second connecting plate includes an upper connecting plate and a lower connecting plate connected to the upper connecting plate, the upper connecting plate is rotatably connected to the mounting component, the lower connecting plate is rotatably connected to the wheel axle of the pressure roller, and the upper connecting plate and the lower connecting plate are at right angles or obtuse angles and are located in the same plane.

[0025] The advantages of this preferred solution are: the upper connecting plate is at a right angle or an obtuse angle with the mounting part, so that the axle of the pressing wheel and the mounting part are not on the same vertical straight line, which can ensure that when the pressing wheel encounters a protrusion, it is lifted upward by the driving force of the connecting plate.

[0026] Preferably, the pressure film adjusting assembly includes a second connecting rod, a first connecting part is provided on the second crossbeam, the first connecting part is provided with a connecting hole, and the second connecting rod passes through the connecting hole and is connected to the lower connecting plate; more preferably, a limiting member is provided on the second connecting rod, and the limiting member is located above the first connecting part; even more preferably, a spring is provided on the second connecting rod, and the spring is located below the first connecting part.

[0027] The beneficial effects of this preferred solution are as follows: when the pressure roller is lifted upward, the second connecting rod moves upward in the connecting hole; when the pressure roller is reset, the second connecting rod moves downward in the connecting hole and is limited by the limiting component; the spring can play a buffering and shock-absorbing role, improving the stability of the pressure roller and the pressure effect.

[0028] Preferably, the support frame includes a third crossbeam connected to the second crossbeam, the third crossbeam having a second connecting portion, and the pressing assembly includes an installation shaft connected to the covering wheel, the installation shaft passing through the second connecting portion and being rotatably connected to the second connecting portion.

[0029] The beneficial effect of this preferred solution is that by setting a third crossbeam, there is a lateral distance between the soil covering wheel and the pressing wheel, which helps to improve the soil covering effect.

[0030] Preferably, the pressing assembly further includes a fixing bolt, a support plate is provided on the mounting shaft, the support plate is provided with an arc-shaped hole, the second connecting part is provided with a fixing hole corresponding to the arc-shaped hole, and the fixing bolt passes through the arc-shaped hole and the fixing hole; more preferably, the center of the arc-shaped hole is located on the central axis of the mounting shaft; even more preferably, the support plate is located above the second connecting part, and the third crossbeam is parallel to the first crossbeam.

[0031] The advantages of this preferred solution are: the mounting shaft is rotatably connected to the second connecting part, which allows the direction of the covering wheel to be adjusted according to the working environment, and it is fixed by fixing bolts, thereby improving the soil covering effect.

[0032] This invention provides a coating apparatus, including a traveling frame, a coating assembly, and the aforementioned coating frame.

[0033] A transmission box is connected to the walking frame. The input end of the transmission box is connected to the power unit, and the transmission box is connected to the film-coating frame.

[0034] The film coating assembly is mounted on the frame and includes a film mounting device and a film winding device.

[0035] The film-attaching device is connected to the frame via a film-attaching adjustment assembly.

[0036] The film winding device is connected to the frame via a film winding adjustment assembly.

[0037] Compared with the prior art, the beneficial effects of the present invention are as follows: by applying the above-mentioned film-covering frame, the support frames on both sides can be independently suspended and adjusted, allowing the pressing wheel and the soil-covering wheel to better adapt to the ground, preventing the film-covering device from tilting or tipping over, and improving the film-covering effect of the film-covering device; the film-hanging adjustment component can adjust the height of the film-hanging device, and the film-wrapping adjustment component can adjust the height of the film-wrapping device, thereby enabling film-covering for different ridge heights or different crop operating environments, and improving the film-covering effect.

[0038] Preferably, the power unit and the transmission box are arranged vertically opposite each other, and the power unit and the transmission box are located in the middle of the walking frame.

[0039] The advantages of this preferred solution are: by placing the power unit and transmission box in the middle of the walking frame, the center of the walking frame is in the middle, which can prevent the film covering device from tipping over due to eccentricity and improve safety.

[0040] Preferably, the mulching device includes opposing plow blades, which are connected to the frame via a plow blade adjustment assembly. The plow blades and the plow blade adjustment assembly are located between the traveling frame and the mulching assembly. Preferably, all plow blades are arc-shaped, or the portion of the plow blades closest to the ground is arc-shaped. More preferably, the arc-shaped openings of any two opposing plow blades are arranged opposite to each other.

[0041] The advantages of this preferred solution are as follows: the plow blade adjustment component can adjust the height of the plow blade to adapt to more working environments; since the vertical cross-section of the ridge is usually trapezoidal during operation, designing the plow blade as an arc with opposite openings can remove the soil from the ridge slope through the plow blade, reducing the width of the ridge, and then the covering wheel will cover the removed soil back onto the film, thereby improving the effect of film covering and soil mounding.

[0042] Preferably, the coating device includes opposing traveling wheels, the axles of which are connected to a traveling frame via a first transmission assembly and a second transmission assembly; preferably, the traveling frame includes traveling frame a and traveling frame b, which are respectively connected to two output ends of a transmission box, and traveling frame a and traveling frame b are on the same straight line; more preferably, the axles of the opposing traveling wheels are all driven to traveling frame a and traveling frame b via the first transmission assembly and the second transmission assembly, respectively, the output ends of traveling frame a and traveling frame b are driven to the input ends of the corresponding first transmission assemblies, the output ends of the first transmission assemblies are driven to the input ends of the corresponding second transmission assemblies, and the output ends of the second transmission assemblies are connected to the axles of the corresponding opposing traveling wheels.

[0043] The advantages of this preferred solution are: the power unit drives the walking wheels through a three-stage transmission to achieve deceleration, which reduces the walking speed of the walking wheels and improves the coating effect.

[0044] This invention provides a coating method, comprising the following steps:

[0045] Place the membrane on the membrane mounting device.

[0046] The membrane is pulled downwards and passes through the first membrane wrapping position, the second membrane wrapping position, and the third membrane wrapping position in sequence before reaching the ground. The path of the membrane between the first membrane wrapping position, the second membrane wrapping position, and the third membrane wrapping position is S-shaped.

[0047] The membrane is pressed at a preset position and then pulled to move in a preset direction.

[0048] Compared with the prior art, the beneficial effects of the present invention are: by conveying the membrane along an S-shape, the conveying path of the membrane can be increased, the friction can be increased, and the membrane can always be kept flat, thereby improving the subsequent coating and soil covering effects.
