Description

Technical Field

[0001] This invention relates to the field of agricultural equipment technology, specifically to a mulching machine. Background Technology

[0002] Mulching refers to the practice of covering the soil surface with agricultural plastic film. It reduces the impact of raindrops, prevents erosion and crust formation; effectively reduces soil moisture evaporation, conserves moisture during droughts and improves moisture levels after rain, promotes crop water absorption and growth, and increases soil water use efficiency. It also helps maintain suitable soil temperature and humidity, slows down soil temperature drop, and prolongs the duration of temperature decline, which is beneficial for waste decomposition and improves soil fertility. Mulching is low-cost, easy to use, and significantly increases yield, making it a commonly used measure that both prevents soil erosion and improves crop yield.

[0003] In the fields of agricultural mechanization and agricultural engineering, the mulching machine is a tool for realizing mechanized mulching cultivation technology. The working process of the mulching machine unit involves using a soil collector to connect the ridges between beds, using a soil divider to collect soil onto the bed surface, using a shaper to create the bed shape according to agronomic requirements while simultaneously compacting the soil, and then evenly laying the film roll along the bed surface using the film-laying mechanism. Finally, the film-pressing and soil-covering mechanism presses the film firmly against the ground, spreads it horizontally, and then covers it with soil and presses it down tightly. However, the beginning and end of the mulching process still require manual intervention. Summary of the Invention

[0004] To address the problem that existing mulching machines still require manual intervention at the beginning and end of the mulching process, this invention provides a mulching machine.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a mulching machine, comprising a machine body, a control device, a transmission device, and a film covering device. The machine body provides film to the film covering device. The control device is mounted on the machine body. One end of the transmission device is connected to the control device, and the other end is connected to the film covering device. The film covering device includes a film clamping assembly, a front film pressing assembly, a film cutting assembly, and a rear film pressing assembly. The film cutting assembly is used to disconnect the film between the end point of the mulching and the machine body. It is mounted on the side of the transmission device away from the control device. The film cutting assembly includes a connecting rod three, a mounting plate, and multiple cutting teeth. One end of the connecting rod three is fixedly connected to the transmission device, and the other end is fixedly connected to the mounting plate. Each cutting tooth is mounted on the mounting plate. The control device drives the cutting teeth upward or downward through the transmission device and the connecting rod three, so that the cutting teeth move away from or insert into the mulch. The clamping assembly is used to clamp the mulch film to be laid and is mounted on the connecting rod three. The clamping assembly includes an adjusting component one and two clamping members. The two clamping members are symmetrically mounted on both sides of the mounting plate, and each clamping member rotates about the mounting plate as a pivot. One end of the adjusting component one is connected to the control device, and the other end is connected to the clamping member. The control device can control the two clamping members to clamp or open through the adjusting component one, so that the two clamping members can clamp or release the mulch film. The front pressing film assembly is used to press the film at the starting position of the mulch film laying and is set between the clamping assembly and the mulch film machine. The front pressing film assembly includes an adjusting component two and a front pressure plate. One end of the adjusting component two is connected to the control device, and the other end is connected to the front pressure plate. The control device can drive the front pressure plate to lift upward or press downward through the adjusting component two. The rear film pressing assembly is used to press the film at the end point of the film laying. It is installed on the connecting rod three and is located on the side of the film clamping assembly away from the film laying machine. The rear film pressing assembly includes an adjusting component three and a rear pressure plate. One end of the adjusting component three is installed on the connecting rod three, and the other end of the adjusting component three is connected to the rear pressure plate. The adjusting component three can drive the rear pressure plate to press downward when the insertion teeth pass through the film and insert into the soil.

[0006] As a further improvement to the above solution, the control device includes a control component one and a control component two. The control component one is installed on the main body of the mulch film machine, and the control component two is installed on the control component one. The control component one is connected to the transmission device, and the control component one can drive the connecting rod three to be raised upward or pressed downward through the transmission device. The film cutting component, the film clamping component, the front pressing film component, and the rear pressing film component will be raised upward or pressed downward along with the connecting rod three. The connecting rod three is also equipped with an adjustment component four. One end of the adjustment component four is connected to the control component two, and the other end of the adjustment component four is connected to the adjustment component one and the adjustment component two respectively. The control component two can synchronously adjust the adjustment component one and the adjustment component two through the adjustment component four, so that the film clamping component opens while the front pressing film component is pressed downward, or the film clamping component clamps while the front pressing film component is raised upward.

[0007] As a further improvement to the above solution, the transmission device includes at least two transmission components, which are symmetrically arranged on both sides of the mulch film machine body. The number of connecting rods three is the same as the number of transmission components, and each connecting rod three is connected to each transmission component. The control component one is provided with a crossbar one, and the two ends of the crossbar one are respectively connected to the two transmission components. The control component one can drive the two transmission components to move synchronously through the crossbar one, so that the two connecting rods three are raised upward or pressed downward.

[0008] As a further improvement to the above solution, the transmission assembly includes a connecting rod one and a connecting rod two. The connecting rod two is rotatably mounted on the side wall of the mulch film machine body. One end of the connecting rod two is connected to one end of the connecting rod one, and the other end of the connecting rod two is connected to the connecting rod three. The other end of the connecting rod one is connected to the crossbar one.

[0009] As a further improvement to the above solution, the adjustment component four includes a connecting rod four and a connecting rod five. Two connecting rods two are fixedly connected to both ends of the connecting rod four. The connecting rod five has inclined rods at both ends, one end of which is fixedly connected to the connecting rod five, and the other end of which is rotatably mounted to the connecting rod three. A spring one is provided between the connecting rod four and the connecting rod five, one end of which is fixedly connected to the connecting rod four, and the other end of which is fixedly connected to the connecting rod five. The adjustment component one and the adjustment component two are respectively connected to the inclined rods. The control component one can synchronously control the adjustment component one and the adjustment component two by rotating the inclined rods via the connecting rod five.

[0010] As a further improvement to the above solution, when the control component two compresses the spring one by pulling the connecting rod five, the connecting rod five synchronously controls the adjusting component one and the adjusting component two through the inclined rod, so that the clamping member opens and the front pressure plate is pressed down; when the control component two exerts no force on the spring one, under the elastic force of the spring, the connecting rod five can synchronously control the adjusting component one and the adjusting component two through the inclined rod, so that the clamping member clamps and the front pressure plate is raised.

[0011] As a further improvement to the above solution, the adjustment component 1 includes at least one pair of connecting rods 6, and the number of the pair of connecting rods 6 is two. A rotating rod is fixedly installed on the inclined rod. One end of each of the two connecting rods 6 is rotatably installed on the rotating rod. The other end of one of the connecting rods 6 is fixedly connected to one of the clamping members, and the other end of the other connecting rod 6 is fixedly connected to the other clamping member.

[0012] As a further improvement to the above solution, the number of adjustment components 2 is two, and the two adjustment components are respectively connected to the two connecting rods 3; the adjustment component 2 includes rod body 1, rod body 2 and rod body 3, one end of rod body 2 is rotatably connected to one end of rod body 1, one end of rod body 2 is connected to one end of rod body 3, the other end of rod body 1 is rotatably mounted on the rotating rod, and the other end of rod body 3 is connected to the front pressure plate.

[0013] As a further improvement to the above solution, the adjusting assembly two also includes a rod four, one end of which is rotatably mounted on the connecting rod three, and the other end of which is rotatably connected to the rod three. Furthermore, the connection point between the rod four and the rod three is below the connection point between the rod two and the rod three.

[0014] As a further improvement to the above solution, there are two adjustment components three, each mounted on one of the two connecting rods three. Each adjustment component three includes a pusher, a second spring, and an adjustment member. A slide rod is provided on the connecting rod three. The second spring is sleeved on the slide rod, with one end of the second spring fixed to the slide rod and the other end of the second spring fixedly mounted with a collar. One end of the pusher is fixedly connected to the collar, and the other end is sleeved on the insertion tooth. One end of the adjustment member is hinged to the collar, and the other end is fixedly connected to the rear pressure plate. When the insertion tooth is inserted into the ground, the pusher moves upward along the insertion tooth, causing the collar to move upward and compress the second spring. The collar then drives the rear pressure plate downward through the adjustment member.

[0015] As a further improvement to the above solution, the first adjustment component and the second adjustment component are disposed between the two third connecting rods, and the third adjustment component is disposed on the outside of the third connecting rod.

[0016] As a further improvement to the above solution, the adjusting component includes rod five, rod six, and rod seven. Rod six is ​​rotatably mounted on the connecting rod three. One end of rod six is ​​rotatably connected to one end of rod five, and the other end of rod six is ​​rotatably connected to one end of rod seven. The other end of rod five is rotatably connected to the collar, and the other end of rod seven is fixedly connected to the rear pressure plate.

[0017] As a further improvement to the above solution, the adjusting component also includes a rod eight, one end of which is rotatably mounted on the connecting rod three, and the other end of which is rotatably connected to the rod seven.

[0018] As a further improvement to the above solution, the pushing component includes a pushing plate and a pushing rod. The pushing plate is sleeved on the insertion tooth, one end of the pushing rod is fixedly connected to the collar, and the other end of the pushing rod is fixedly connected to the pushing plate.

[0019] As a further improvement to the above solution, the control component includes a hand lever and a fixed rod. The fixed rod is fixed to the body of the mulch film machine. The middle part of the hand lever is rotatably mounted on the fixed rod. One end of the hand lever is rotatably connected to the crossbar. By controlling the hand lever and under the action of the transmission device, the connecting rod can be raised or pressed.

[0020] As a further improvement to the above solution, the control component two includes a handbrake and a connecting rope. The handbrake is mounted on the hand lever, one end of the connecting rope is connected to the handbrake, and the other end of the connecting rope passes through the axis of the spring one and is connected to the connecting rod five. The handbrake can pull the connecting rod five through the connecting rope, and the connecting rod five can compress the spring one.

[0021] As a further improvement to the above solution, each of the clamping members is provided with multiple arc-shaped rods, the number of arc-shaped rods on the two clamping members corresponds to each other, and two corresponding arc-shaped rods on the two clamping members can form a gripper.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) By setting up a control device and a front pressing film assembly, the control device can press the film at the starting point of the mulching after the mulching machine body travels to the position where the film needs to be laid, so that the mulching film can be firmly pressed into the soil, realizing automated pressing operation at the starting point of the mulching. The whole pressing operation is simple and convenient, and the pressing effect is good.

[0024] (2) By setting up an adjustment component two and a front pressure plate, the control device controls the adjustment component two, which drives the front pressure plate downward to press the mulch film on the soil surface into the soil, thereby realizing automatic mulch film pressing operation. In addition, the front pressure plate in this invention is a slender pressure plate, which can press the mulch film at various positions, improving the pressing effect of the mulch film.

[0025] (3) This invention, by setting up a rear film-pressing assembly and a film-cutting assembly, allows the film-cutting assembly to insert downwards into the mulch film when the mulch film machine reaches the end position of the mulching process, thereby cutting the mulch film. Simultaneously, by configuring a pushing component, the pushing component pushes the adjusting component three under the reaction force of the soil as the cutting teeth are inserted. The adjusting component three then drives the rear pressure plate to press the mulch film at the end position. Therefore, this invention, by setting up a film-cutting assembly and a rear film-pressing assembly, can achieve the breaking and pressing of the mulch film at the end position of the mulching process through mutual cooperation. The entire breaking and pressing process is carried out mechanically, effectively replacing the manual operation in the prior art, greatly improving its operating efficiency and effect.

[0038] The present invention will now be further described in conjunction with specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0039] In the description of this invention, it should be noted that directional terms such as "center," "lateral," "longitudinal," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific scope of protection of this invention. The terms "first," "second," etc., in the specification and claims of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. The terms "comprising" and "having," and any variations thereof, in the specification and claims of this invention, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices.

[0040] Reference Figure 1 As shown, an embodiment of the present invention provides a mulching machine, including a mulching machine body 1, a control device, a transmission device, and a film covering device. The mulching machine body 1 is used to supply film to the film covering device. The control device is installed on the mulching machine body 1. One end of the transmission device is connected to the control device, and the other end of the transmission device is connected to the film covering device.

[0041] The mulching machine body 1 can also be a rice transplanter, enabling it to transplant rice seedlings while covering the film.

[0042] like Figures 2 to 4 As shown, the mulching device includes a film clamping assembly 42, a front film pressing assembly 43, a film cutting assembly 41, and a rear film pressing assembly 44. The film clamping assembly 42 is used to clamp the mulch film to be laid, the front film pressing assembly 43 is used to press the film at the starting point of the mulch film laying, the film cutting assembly 41 is used to disconnect the film between the ending point of the mulch film laying and the mulch film machine body 1, and the rear film pressing assembly 44 is used to press the film at the ending point of the mulch film laying, so that the mulch film is pressed into the soil.

[0043] like Figure 3 and Figure 4As shown, the film-cutting assembly 41 includes a connecting rod 411, one end of which is fixedly connected to the side of the transmission device away from the control device. The front film-pressing assembly 43, the film-clamping assembly 42, and the rear film-pressing assembly 44 are all mounted on the connecting rod 411, so that the transmission device can drive the film-clamping assembly 42, the front film-pressing assembly 43, and the rear film-pressing assembly 44 to be raised upward or lowered downward through the connecting rod 411.

[0044] Please see Figure 3 and Figure 4 The number of connecting rods 411 is two. The membrane cutting assembly 41 also includes a mounting plate 412 and multiple insertion teeth 413. The two ends of the mounting plate 412 are transversely on the side away from the transmission device on the two connecting rods 411. Each insertion tooth 413 is installed vertically on the mounting plate 412. The control device can drive the insertion teeth 413 to be raised upward or pressed downward through the transmission device and the connecting rods 411, so that the insertion teeth 413 are away from or inserted into the mulch film. When a membrane cutting operation is required, the control device can drive the insertion teeth 413 downward to be inserted into the mulch film, thereby allowing the multiple insertion teeth 413 to penetrate the mulch film and realize the membrane cutting operation.

[0045] The membrane clamping assembly 42 includes an adjustment assembly and two clamping members 421. The two clamping members 421 are symmetrically mounted on both sides of the mounting plate 412, and each clamping member 421 rotates about the mounting plate 412 as a pivot. One end of the adjustment assembly is connected to each of the two clamping members 421, and the other end is connected to a control device. The control device can use the adjustment assembly to drive the two clamping members 421 to clamp or open, so that the two clamping members 421 can clamp or release the mulch film.

[0046] Before the film laying operation, the adjusting component 1 can be controlled by the control device to clamp the film with two clamping parts 421. After the clamping parts 421 are clamped, the clamping component 42 is moved upward by the control device until it is away from the ground. Then, the film laying machine body 1 is started, allowing it to travel to the position where film laying is required. The above operation is the preliminary work for the film laying operation. By setting the clamping component 42, at the starting position of film laying, the clamping component 42 can place the film on the ground and work with the front pressing component 43 to press the film at the starting position of the laying. When it is not necessary to clamp the film, the adjusting component 1 can be controlled by the control device to open the two clamping parts 421, so that the clamping parts 421 do not clamp the film.

[0047] like Figure 8 and Figure 9As shown, the front pressing membrane assembly 43 is positioned between the clamping membrane assembly 42 and the mulch film machine, and is used to press the membrane at the starting point of the mulch film laying operation. The front pressing membrane assembly 43 includes an adjusting component two and a front pressure plate 431. One end of the adjusting component two is connected to a control device, and the other end is connected to the front pressure plate 431. The control device can use the adjusting component two to drive the front pressure plate 431 to be raised or lowered. When the mulch film machine body 1 travels to the film laying position, the control device can first drive the clamping membrane assembly 42 and the front pressing membrane assembly 43 downward through the transmission device, so that the clamping membrane assembly 42 contacts the soil. At this time, the clamping membrane assembly 42 clamps the mulch film to be laid. Then the clamping membrane assembly 42 is released, and the mulch film is laid on the soil. Then, the control device controls the adjustment component two, which drives the front pressure plate 431 to press down. The front pressure plate 431 presses the mulch film laid on the soil surface into the soil, thereby achieving the pressing operation of the mulch film at the starting position of the mulch film laying.

[0048] like Figure 11 As shown, the rear film pressing assembly 44 is installed on the connecting rod 3 411 and positioned on the side of the film clamping assembly 42 away from the mulch film machine. It is used to press the film at the end point of the mulch film laying. The rear film pressing assembly 44 includes an adjusting assembly 3 and a rear pressure plate 441. One end of the adjusting assembly 3 is installed on the connecting rod 3 411, and the other end of the adjusting assembly 3 is connected to the rear pressure plate 441. The adjusting assembly 3 can drive the rear pressure plate 441 to press downward when the insertion teeth 413 pass through the mulch film and insert into the soil. When the mulch film machine body 1 finishes laying the film and moves to the end point of the mulch film laying, the film cutting assembly 41 can be driven to move downward through the control device. The insertion teeth 413 can be inserted into the mulch film laid on the ground. At the same time, since the insertion teeth 413 are inserted into the soil, the adjusting assembly 3 can drive the rear pressure plate 441 to press downward. The rear pressure plate 441 can press the mulch film into the soil, thus completing the pressing operation of the mulch film at the end point of the laying. Then, the mulching machine body 1 is started again, and the mulching machine body 1 can move forward, so that the film between the mulching machine body 1 and the rear pressure plate 441 can be torn apart from the insertion tooth 413, thereby completely separating the mulch film on the mulching machine body 1 from the mulch film laid on the ground, thus completing the entire mulching process.

[0049] In this embodiment, both the front pressure plate 431 and the rear pressure plate 441 are slender pressure plates. By setting them to slender structures, it is possible to perform pressing operations on various positions of the mulch film, thereby improving the pressing effect of the mulch film.

[0050] like Figure 7As shown, in some embodiments, the control device includes a control component 21 and a control component 22. The control component 21 is mounted on the main body 1 of the mulching machine, and the control component 22 is mounted on the control component 21. Mounting the control component 22 on the control component 21 effectively saves the space occupied by the entire control device. The control component 21 is connected to a transmission device, which allows the control component 21 to drive the connecting rod 411 to be raised or pressed down. The film cutting component 41, the film clamping component 42, the front film pressing component 43, and the rear film pressing component 44 will be raised or pressed down along with the connecting rod 411. Therefore, during the film covering operation, the position of the film covering device can be adjusted according to the actual situation to meet the actual needs. The connecting rod 3 411 is also equipped with an adjustment component 4. One end of the adjustment component 4 is connected to the control component 2 22, and the other end is connected to both the adjustment component 1 and the adjustment component 2. The control component 2 22 can synchronously adjust the adjustment components 1 and 2 through the adjustment component 4, so that the clamping component 42 opens while the front pressure film component 43 is pressed downward, or the clamping component 42 clamps while the front pressure film component 43 is raised upward. By setting the adjustment component 4, the clamping member 421 and the front pressure plate 431 can be synchronously adjusted through the control component 2 22, which simplifies the structure of the entire device and the operation of the entire control device. In this embodiment, by setting the control component 1 21 and the control component 2 22 to control different operations respectively, the control of the entire control device is clearly divided and the control effect is good.

[0051] Adjustment component one and adjustment component two are located between two connecting rods three 411, while adjustment component three is located on the outside of connecting rod three 411. This ensures that the movements of adjustment component one, adjustment component two, and adjustment component three do not interfere with each other, thereby improving the stability of each adjustment component during movement.

[0052] like Figures 5 to 7As shown, specifically, control component 21 includes a hand lever 212 and a fixed rod 213. The fixed rod 213 is fixed to the main body 1 of the mulch film machine. The middle part of the hand lever 212 is rotatably mounted on the fixed rod 213. One end of the hand lever 212 is rotatably connected to the crossbar 211. By controlling the hand lever 212 and under the action of the transmission device, the connecting rod 411 can be raised or lowered, so as to drive the insert tooth 413, the front pressure plate 431, and the rear pressure plate 441 to move upward or downward through the connecting rod 411. When performing the film clamping operation, the hand lever 212 can be controlled to drive the transmission device to move. The transmission device can drive the connecting rod 411 to move downward, so that the connecting rod 411 drives the film clamping assembly 42 to move downward until it is flush with the part of the mulch film placed in the main body 1 of the mulch film machine. Then the mulch film is pulled out and clamped by the film clamping assembly 42. After the clamping assembly 42 clamps the mulch film, the hand lever 212 is controlled to drive the connecting rod 411 upward via the transmission device, thereby raising the entire mulching device. By controlling the entire mulching device to rise, the mulching device will not contact the ground when the mulching machine body 1 is moving, thus protecting the mulching device and the mulch film. When a pressing operation is required, the hand lever 212 can drive the transmission assembly 3, which in turn drives the connecting rod 411 downward until the mulching device contacts the soil. In this embodiment, by setting the control assembly 21, the entire mulching device can be effectively controlled to rise or fall.

[0053] like Figure 7 As shown, control component 22 includes a handbrake 221 and a connecting rope 222. The handbrake 221 is mounted on the pull rod 212. One end of the connecting rope 222 is connected to the handbrake 221, and the other end of the connecting rope 222 passes through the axis of the spring 54 and is connected to the connecting rod 52. The handbrake 221 can pull the connecting rod 52 through the connecting rope 222, and the connecting rod 52 can compress the spring 54.

[0054] like Figure 3 and Figure 7As shown, in some embodiments, the adjusting component four includes a connecting rod four 51 and a connecting rod five 52. Two connecting rods two 32 are fixedly connected to both ends of the connecting rod four 51. The connecting rod five 52 has inclined rods 53 at both ends. One end of the inclined rod 53 is fixedly connected to the connecting rod five 52, and the other end is rotatably mounted on the connecting rod three 411. A spring one 54 is provided between the connecting rod four 51 and the connecting rod five 52. One end of the spring one 54 is fixedly connected to the connecting rod four 51, and the other end is fixedly connected to the connecting rod five 52. Adjusting component one and adjusting component two are respectively connected to the inclined rods 53. Control component one 21 can synchronously control adjusting component one and adjusting component two by rotating the inclined rods 53 via the connecting rod five 52. By setting adjusting component four, the structure of control component two 22 controlling the film clamping component 42 and the pre-pressing film component 43 can be effectively simplified.

[0055] like Figures 7 to 9 As shown, the control component 22 controls the specific operation of the clamping component 42 and the front pressing component 43 through the adjustment component 4, as follows: When the handbrake 221 is gripped, the handbrake 221 pulls the connecting rope 222, which drives the connecting rod 52 to rotate along the inclined rod 53. The spring 54 is compressed, and at this time, the inclined rod 53 drives the two clamping parts 421 to open through the adjustment component 1, and the plastic film clamped between the two clamping parts 421 is released. At the same time, the adjustment component 2, under the action of the inclined rod 53, drives the front pressing plate 431 to press down, so that the front pressing plate 431 can press the plastic film released from the clamping parts 421 into the soil. This operation can be performed at the starting position of the plastic film laying. Through the above operation, the plastic film at the starting position of the plastic film laying can be pressed down. The whole operation process is simple, convenient and highly automated.

[0056] When the handbrake 221 is released, the connecting rod 52 returns to its original position under the elastic force of the spring 54. At this time, the inclined rod 53 can drive the clamping member 421 to return to the clamping state through the adjusting component 1, and at the same time, the adjusting component 2 can drive the front pressure plate 431 to return to the unpressed position. Therefore, in this application, the clamping member 421 and the front pressure plate 431 can be in different states by gripping or releasing the handbrake 221.

[0057] like Figure 9As shown, the adjustment assembly includes at least one pair of connecting rods 422. In this embodiment, there are two connecting rods 422. A rotating rod is fixedly mounted on the inclined rod 53, and one end of each of the two connecting rods 422 is rotatably mounted on the rotating rod. The other end of one connecting rod 422 is fixedly connected to one of the clamping members 421, and the other end of the other connecting rod 422 is fixedly connected to the other clamping member 421. Therefore, in this embodiment, the connecting rods 422 can be moved by rotating the inclined rod 53, thereby controlling the clamping or opening of the two clamping members 421.

[0058] It is understood that in some embodiments, such as Figure 9 As shown, each clamping member 421 is provided with multiple arc-shaped rods, the number of arc-shaped rods on the two clamping members 421 corresponds to each other, and two corresponding arc-shaped rods on the two clamping members 421 can form a gripper.

[0059] like Figure 4 and Figure 9 As shown, there are two adjustment components, each connected to two connecting rods 411. By using two adjustment components, the stability of the front pressure plate 431 can be further improved, allowing the front pressure plate 431 to smoothly press the mulch film into the soil, thus achieving the compaction operation of the mulch film at the starting point of the laying. Adjustment component two includes rod 432, rod 433, and rod 434. One end of rod 433 is rotatably connected to one end of rod 432, and one end of rod 433 is connected to one end of rod 434. The other end of rod 432 is rotatably mounted on a rotating rod, and the other end of rod 434 is rotatably connected to the front pressure plate 431. In this application, the connection position between rod 432 and diagonal rod 53 and the connection position between connecting rod 422 and diagonal rod 53 are both at the rotating rod position. This enables the connecting rod 422 and rod 432 to move synchronously when the rotating rod is driven by diagonal rod 53, so as to simultaneously change the position of clamping member 421 and front pressure plate 431.

[0060] When the membrane pressing operation is required, the handbrake 221 can be tightened to pull the connecting rope 222. The connecting rope 222 can drive the connecting rod 52 to rotate along the inclined rod 53. Under the action of the inclined rod 53, the rod 1 432, the rod 2 433 and the rod 3 434 move. The rod 3 434 drives the front pressure plate 431 to press down, so that the front pressure plate 431 can press the detached membrane of the clamping member 421 into the soil, thereby completing the membrane pressing operation.

[0061] In this embodiment, rod 1 432, rod 2 433, and rod 3 434 are interconnected, which can effectively control the downward pressing of the front pressure plate 431 to achieve the film pressing operation. At the same time, the middle position of rod 2 433 is rotatably mounted on connecting rod 3 411, thereby ensuring the stability of the entire adjustment assembly 2 during its movement.

[0062] In some embodiments, the adjusting assembly two further includes a rod four 435, one end of which is rotatably mounted on a connecting rod three 411, and the other end of which is rotatably connected to a connecting rod three 434. The arrangement of the rod four 435 can further improve the stability of the entire adjusting assembly two during the linkage process.

[0063] There are two adjustment components, each mounted on a connecting rod 411. Each adjustment component includes a pusher, a second spring 444, and an adjusting member. A sliding rod 4111 is mounted on the connecting rod 4111. The second spring 444 is sleeved on the sliding rod 4111, with one end fixed to the sliding rod 4111 and the other end fixedly mounted with a collar 4441. One end of the pusher is fixedly connected to the collar 4441, and the other end is sleeved on the insert tooth 413. One end of the adjusting member is hinged to the collar 4441, and the other end is fixedly connected to the rear pressure plate 441. When the insertion tooth 413 passes through the mulch film laid on the soil surface and inserts into the soil, the pushing member moves upward along the insertion tooth 413 under the reaction force of the soil, driving the collar 4441 to move upward and compress the spring 444. At this time, the collar 4441 can drive the rear pressure plate 441 to press downward through the adjusting member. Thus, while the insertion tooth 413 initially inserts and cuts the mulch film, the pushing member and the adjusting member can drive the rear pressure plate 441 to press the mulch film at the end of the laying position into the soil, thereby realizing the mulch film pressing operation.

[0064] like Figure 4As shown, the pushing component includes a pushing plate 442 and a pushing rod 443. The pushing plate 442 is sleeved on the insert tooth 413. One end of the pushing rod 443 is fixedly connected to a collar 4441, and the other end of the pushing rod 443 is fixedly connected to the pushing plate 442. The adjusting component includes rod body five 445, rod body six 446, and rod body seven 447. Rod body six 446 is rotatably mounted on connecting rod three 411 to ensure the stability of the entire adjusting component during movement. One end of rod body six 446 is rotatably connected to one end of rod body five 445, and the other end of rod body six 446 is rotatably connected to one end of rod body seven 447. The other end of rod body five 445 is rotatably connected to the collar 4441, and the other end of rod body seven 447 is fixedly connected to the rear pressure plate 441. Specifically, when the insertion tooth 413 penetrates the mulch film and inserts into the soil, the reaction force of the soil pushes the push plate 442 upward. The push plate 442 then compresses the spring 444 via the push rod 443. The spring 444 is compressed, and through the rods 445, 446, and 447, it drives the rear pressure plate 441 downward, thus pressing the mulch film into the soil. This achieves the pressing operation of the mulch film at the end of the laying process. In this embodiment, by setting up the pusher, the mulch film at the end of the laying process can be pressed into the soil at the same time as the film needs to be cut after laying, thereby achieving the simultaneous cutting and pressing of the mulch film into the soil to complete the entire mulching operation.

[0065] In this embodiment, rods 445, 446, and 447 are interconnected. Therefore, by controlling rod 445, the rear pressure plate 441 can be controlled through the interconnected movement of rods 446 and 447.

[0066] In other embodiments, the adjusting member further includes a lever 448, one end of which is rotatably mounted on a connecting lever 411, and the other end of which is rotatably connected to a lever 447. The lever 448 further enhances the stability of the adjusting member during operation.

[0067] like Figure 2As shown, the transmission device includes at least two transmission components 3, which are symmetrically arranged on both sides of the mulch film machine body 1. The number of connecting rods 411 is the same as the number of transmission components 3, and each connecting rod 411 is connected to each transmission component 3. The control component 21 is provided with a crossbar 211, and the two ends of the crossbar 211 are respectively connected to the two transmission components 3. The control component 21 can drive the two transmission components 3 to move synchronously through the crossbar 211, so that the two connecting rods 411 can be raised or pressed down synchronously. By setting two transmission components 3 and two connecting rods 411, the stability of raising or lowering the film clamping component 42, the film cutting component 41, the front film pressing component 43, and the rear film pressing component 44 through the transmission components 3 and the connecting rods 411 can be improved.

[0068] like Figure 10 and Figure 11 As shown, the transmission assembly 3 includes a connecting rod 31 and a connecting rod 32. The connecting rod 32 is rotatably mounted on the side wall of the mulch film machine body 1. One end of the connecting rod 32 is connected to one end of the connecting rod 31, and the other end of the connecting rod 32 is connected to the connecting rod 411. The two ends of the crossbar 211 are respectively horizontally connected to the two connecting rods 31, so that the control assembly 21 can synchronously control the two transmission assemblies 3 through the crossbar 211. In this embodiment, the connecting rod 32 is rotatably connected to the mulch film machine body 1, which enables the control assembly 21 to drive the connecting rod 31 to move through the crossbar 211. The connecting rod 31 acts on the connecting rod 32, so that the connecting rod 32 can rotate around the connection point with the mulch film machine body 1, thereby driving the connecting rod 411 to move downwards or downwards.

[0069] The specific operation process of the mulching machine in this invention is as follows: Before mulching, the film clamping assembly can be moved downwards to be flush with the main body of the mulching machine by the control component 21 (e.g., Figure 1 (As shown). Then, the clamping element is opened by controlling component two (as shown). Figures 2 to 4 (As shown), the plastic film is then manually placed onto the clamping assembly 42, allowing the clamping assembly 42 to clamp the plastic film. The entire film covering device is then moved upwards via the control assembly 21 (as shown). Figure 5 (As shown), then start the mulching machine body 1, so that it travels to the starting position of mulching in the field, and then the control component 21 drives the transmission device to control the film clamping component 42 to press down (as shown). Figures 6 to 7As shown), the film is placed into the soil of the paddy field, and then the film clamping assembly 42 is opened, allowing the mulch film to be placed on the soil. Simultaneously, under the control of control assembly 22 and adjustment assembly 4, the front pressure plate 431 in the front pressure film assembly 43 presses the mulch film between the film clamping assembly 42 and the mulch film machine body 1, thereby achieving the pressing operation of the film at the starting point of the film laying (as shown). Figures 8 to 9 (As shown). Then, the entire film-coating device is raised by the transmission device driven by the control component 21 (as shown). Figure 10 (As shown), simultaneously start the mulching machine body 1, enabling it to drive the mulch film to be laid in the paddy field. When the mulch film reaches its end point, the control component 22 drives the transmission device to open the clamping component 42. This opening prepares for laying a new section of mulch film. Then, the control component 21 controls the entire mulching device to press downwards, causing the insertion teeth 413 to insert into the mulch film laid on the soil surface. Under the action of the pushing and adjusting components, the rear pressure plate 441 presses the mulch film at the end point into the soil, thus achieving a pressing operation on the mulch film at the end point (e.g., ...). Figure 11 (As shown). After compaction, the mulch film machine body 1 moves forward to completely break the mulch film, thus completing the laying of a certain length of mulch film.
