Description

Technical Field

[0001] This utility model relates to agricultural machinery and equipment, and more particularly to a waste plastic film collector. Background Technology

[0002] The use of waste plastic film in agricultural production is becoming increasingly widespread. It has multiple functions, including heat preservation, moisture retention, and weed suppression, playing a crucial role in improving crop yield and quality. However, if waste plastic film is not cleaned up in a timely manner, it will remain in the soil, causing soil pollution, affecting soil aeration and permeability, thus negatively impacting crop growth and development, reducing soil fertility, and threatening the sustainable development of agriculture.

[0003] Currently, several types of waste plastic film recycling devices have been launched on the market. These devices mainly consist of a pickup mechanism and a temporary storage box. The pickup mechanism is responsible for picking up the waste plastic film from the ground, while the temporary storage box is used to temporarily store the picked-up film. The device is connected to agricultural mobile equipment such as tractors via a support frame, allowing it to move flexibly in farmland.

[0004] However, existing waste plastic film recycling devices have a significant problem: when transferring waste plastic film to the temporary storage box, a large amount of soil is often brought in along with it. This is because the picking mechanism usually needs to insert itself into the soil when picking up the waste plastic film, causing the soil to easily be pushed onto the top of the waste plastic film. During the accumulation of waste plastic film, a large amount of soil becomes wrapped and entangled. The soil entering the temporary storage box not only increases the difficulty of subsequent cleanup but also adds to the load of the temporary storage box, affecting the effective storage capacity of the temporary storage box and the overall operating efficiency of the device.

[0005] In summary, existing waste plastic film recycling devices face many problems that urgently need to be solved in practical applications. There is an urgent need to develop a new type of waste plastic film recycling device to prevent soil from entering the temporary storage box, reduce the amount of subsequent cleaning work, and reduce the load of the temporary storage box. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention proposes a waste plastic film collector. This collector effectively prevents soil from entering the temporary storage box, thereby reducing the burden of subsequent cleanup work. This design solves the problem of soil easily entering the temporary storage box in existing devices.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A waste plastic film collector includes a picking mechanism and a temporary storage box arranged side by side. The picking mechanism includes multiple chain drive components arranged front to back, which are connected by a synchronous shaft I. Picking claws are provided on the outer sides of the multiple chain drive components, and these claws reciprocate with the chain drive components. Multiple support plates are also provided between adjacent chain drive components, each corresponding to a link of a single chain drive component. Both ends of each support plate are fixedly connected to the links of the corresponding chain drive component. A vibration component is provided on the inner side of the multiple chain drive components. The vibration component includes multiple cams arranged in a rectangular array. The maximum distance between the central axis of each cam and its side end is greater than the distance between the central axis of the cam and the support plate, and the minimum distance between the central axis of each cam and its side end is less than the distance between the central axis of the cam and the support plate. Each support plate has a through-hole for soil leakage. Multiple cams are arranged in a rectangular array on the inner side of the multiple support plates in the same vertical plane.

[0009] Preferably, the vibration component further includes multiple synchronous shafts II arranged side by side and in the front-back axial direction. The synchronous shafts II are connected to a cam drive in the same vertical plane. At the same time, a chain synchronous component is provided on one side of two adjacent synchronous shafts II, and the chain synchronous component is connected to the corresponding synchronous shaft II for transmission.

[0010] Preferably, the projection of each support plate on the vertical plane is a U-shaped structure, the U-shaped opening of the support plate faces the synchronous shaft II, and the distance between the outer end of the support plate and the central axis of the synchronous shaft II is greater than the distance between the outer end of the chain drive component and the central axis of the synchronous shaft II.

[0011] Preferably, each of the support plates has a plurality of soil leakage holes through it on the side away from the synchronous shaft II, and the plurality of soil leakage holes are arranged side by side from front to back, and the length of each soil leakage hole is not less than one-quarter of the length of the corresponding support plate.

[0012] Preferably, a support frame is provided on the lower side of the picking mechanism, and synchronous shaft I and synchronous shaft II are rotatably connected to the support frame. Furthermore, a support wheel is rotatably connected to the lower side of the support frame, and a chain drive component is provided between the support wheel and synchronous shaft I, and between synchronous shaft I and synchronous shaft II.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention designs a support plate positioned between adjacent chain drive components, allowing it to move synchronously with the chain links, thus providing stable additional support for waste plastic film. The support plate has through-holes for soil drainage, and a vibration mechanism consisting of multiple rectangular array cams is installed inside the chain drive components. When the cams rotate, they effectively drive the support plate to vibrate, thereby promoting efficient separation of soil and plastic film. This design effectively prevents waste plastic film carrying soil from entering the temporary storage box, reducing the difficulty of subsequent cleaning, alleviating the additional burden on the temporary storage box, and simultaneously improving the effective storage capacity of the temporary storage box and the overall operating efficiency of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0025] Please refer to Figure 1 and Figure 7 This utility model relates to a waste plastic film collector, the structure of which is consistent with existing technology devices. It mainly consists of left and right picking mechanisms 2 arranged side-by-side and a temporary storage box 1. The temporary storage box 1 is used to temporarily store the collected plastic film. Of particular note is that the picking mechanism 2 and the temporary storage box 1 are both equipped with a support frame 209 on their lower sides. Figure 7 As shown, a triangular-structured mating frame is cleverly configured on one side of the support frame 209. This mating frame can seamlessly connect with existing drive devices (such as tractors or other agricultural production mobile devices) to ensure that the drive device can effectively pull the device to move smoothly in the agricultural production environment.

[0026] Therefore, to reduce resistance during movement, this device has support wheels 208 on the lower side of the support frame 209. The support wheels 208 work in conjunction with the mounting frame to prevent the picking mechanism 2 and the temporary storage box 1 from directly contacting the ground, thereby reducing frictional resistance. Specifically, as... Figure 1 and Figure 2 Clearly shown, the picking mechanism 2 consists of multiple chain-driven components 201 arranged side-by-side. These components are connected via a synchronous shaft I 202, meaning the gears within each chain-driven component 201 are connected via the synchronous shaft I 202, ensuring that the multiple chain-driven components 201 can move synchronously.

[0027] In addition, multiple chain drive components 201 are equipped with picking claws on their outer sides. By fixing the picking claws to the chain links of the chain drive components 201, the picking claws can reciprocate with the chain drive components 201. This design allows the device to fully utilize the structural advantages of the chain drive components 201 in actual operation. When the picking claws move linearly below the support frame 209, they effectively push the waste plastic film to form an accumulation. Subsequently, the accumulated waste plastic film moves with the picking claws to above the chain drive components 201. With the help of the transfer function of the chain drive components 201, the waste plastic film is finally safely accumulated in the temporary storage box 1. It is particularly noteworthy that, as Figure 7As shown, the temporary storage box 1 is designed with a clearance groove for the picking claw. This design aims to prevent the claw from interfering with the box body and to ensure that the waste plastic film can be effectively intercepted by the temporary storage box 1.

[0028] like Figure 3 , Figure 4 As shown, the difference between this device and existing technology devices is that multiple support plates 204 are added between adjacent chain drive components 201. The support plates 204 correspond one-to-one with the chain links of the chain drive components 201 and are fixedly connected to ensure that the support plates 204 can move synchronously with the chain links.

[0029] It should be noted that the single layer of plastic film is relatively thin, and its resistance to deformation is insufficient when stacked. Therefore, in practical applications, if the waste plastic film is simply piled on top of the chain drive component 201, it is likely to slip off between the chain drive components 201 due to its own gravity. The support plate 204 effectively supports the plastic film, allowing it to be smoothly driven by the chain drive component 201.

[0030] Therefore, as Figure 5 As shown, the support plate 204 ensures that the waste plastic film only contacts the support plate 204 in actual application, avoiding direct contact with the chain drive component 201, thereby preventing the plastic film from getting tangled between the chain links of the chain drive component 201, avoiding mechanical failure and subsequent cleaning difficulties.

[0031] Furthermore, in practical applications, the pick-up claw usually needs to be inserted into the soil to ensure that the waste plastic film can be pushed. During this process, the soil may be pushed on top of the waste plastic film, causing the soil to be wrapped and entangled by the film when piled up.

[0032] To prevent soil-laden waste plastic film from entering the temporary storage box 1, which would cause cleaning difficulties and additional load, this device has a soil leakage hole 205 on the support plate 204 to filter the soil.

[0033] like Figure 5 As shown, to further ensure the removal of soil from inside the waste plastic film, this device has a vibration component 206 installed on the inner side of multiple chain drive components 201. The vibration component 206 drives the support plate 204 to vibrate, thereby achieving effective separation of soil and plastic film.

[0034] Specifically, the vibrating component 206 consists of a rectangular array of cams 2061. By adjusting the distance between the central axis of the cams 2061 and the support plate 204, it is ensured that the cams 2061 periodically contact and separate from the support plate 204 during rotation. When the maximum distance end of the cams 2061 contacts the support plate 204, it pushes the support plate 204 to vibrate; when the minimum distance end of the cams 2061 is opposite to the support plate 204, the support plate 204 returns to its original position. This cycle repeats, achieving the vibration effect of the support plate 204. During the vibration process, the soil attached to the mulch film falls off through the soil leakage holes 205, thereby achieving the purpose of soil removal.

[0035] It should be pointed out that, as Figure 5 As shown, the central axis of cam 2061 and the central axis of synchronous shaft I 202 are not on the same horizontal plane, and the height of the central axis of cam 2061 is higher than the height of the central axis of synchronous shaft I 202. This design ensures that cam 2061 only contacts the upper support plate 204, effectively preventing cam 2061 from impacting the lower support plate 204, thereby avoiding changes in the depth of the picking claw in the soil and reducing unnecessary resistance.

[0036] In addition, such as Figure 5 As shown, the adjacent cams 2061 are designed with different orientations. This innovation increases the number of contacts between the vibrating component 206 and the support plate 204, thereby ensuring the efficiency of the device in soil removal operations.

[0037] In addition, such as Figure 5 , Figure 6 As shown, in order to ensure that the cam 2061 can directly contact the support plate 204 and maintain the correspondence between the cam 2061 and the support plate 204, this device specifies that multiple cams 2061 are arranged in a rectangular array on the inner side of multiple support plates 204 in the same vertical plane.

[0038] Furthermore, the vibrating component 206 also includes multiple synchronous shafts II arranged side-by-side and in the front-back axial direction.

[0039] 2062, the synchronous shaft II 2062 is connected to the cam 2061, which is located in the same vertical plane. The rotation of the synchronous shaft II 2062 can drive the cam 2061 to rotate synchronously, ensuring the consistency of vibration effect.

[0040] Each of the two adjacent synchronous shafts II 2062 is equipped with a chain synchronization component 207 on one side, and these components are connected to the corresponding synchronous shafts II 2062 for transmission. The chain synchronization component 207 ensures the synchronous rotation between adjacent synchronous shafts II 2062, so that the entire vibration component 206 can work stably and in a coordinated manner.

[0041] Furthermore, in practical applications, since the chain and corresponding gear within the chain drive component 201 are movably connected, to prevent derailment between the chain and the corresponding gear, this device specifies that the projection of each support plate 204 in the vertical plane is a U-shaped structure, with the U-shaped opening of the support plate 204 facing the synchronous shaft II 2062. The U-shaped structure design makes the support plate 204 a thin-plate component, possessing a certain deformation capacity. When the cam 2061 impacts the support plate 204, the support plate 204 can buffer the impact through its own deformation, thereby preventing the chain from changing position and ensuring normal meshing between the chain and the gear.

[0042] In addition, this device is precisely designed to ensure that the distance between the outer end of each support plate 204 and the central axis of the synchronous shaft II 2062 is greater than the distance between the outer end of the chain drive component 201 and the synchronous shaft II 2062, thereby making the support plate 204 protrude relative to the chain drive component 201, achieving a specific technical effect.

[0043] Furthermore, this device has multiple soil-draining holes 205 on the side of each support plate 204 away from the synchronous shaft II 2062, and these soil-draining holes 205 are arranged side by side in the front-back direction. By unidirectional arrangement, the total size of the soil-draining holes 205 is increased, thereby ensuring that the soil can be smoothly separated from the mulch film (i.e., support plate 204).

[0044] Accordingly, this device specifies that the length (front and back length) of each soil leakage hole 205 is not less than one-quarter of the length (front and back) of the corresponding support plate 204. This not only ensures a larger size of the soil leakage hole 205, ensuring that the soil falls smoothly and improving the soil removal efficiency, but also further breaks the rigidity of the support plate 204, making the support plate 204 more flexible, ensuring that the support plate 204 can spontaneously deform under the impact of the cam 2061.

[0045] like Figure 2 , Figure 7 , Figure 7 As shown, to achieve the rotation of the chain drive component 201 and the chain synchronization component 207, that is, to ensure that the device can push the waste plastic film in practice, and to ensure that the cam 2061 can strike the support plate 204, the device is equipped with a chain transmission component 203 between the support wheel 208 and the synchronization shaft I 202, and between the synchronization shaft I 202 and the synchronization shaft II 2062. The support wheel 208 drives the waste plastic film collector to move flexibly on the ground, and the chain transmission component 203 is responsible for transmitting power from the support wheel 208 to the synchronization shaft I 202 and the synchronization shaft II 2062, thereby driving the picking mechanism 2 and the vibration component 206 to work together.

[0046] In the actual application of this utility model, the specific steps are as follows:

[0047] 1. Preparation and Start-up Phase: Connect the waste plastic film pickup to the drive unit (e.g., a tractor) via the mounting bracket. After starting the drive unit, the pickup moves across the farmland.

[0048] 2. Mulch Film Picking Stage: The operation of the drive device drives the support wheel 208 to rotate, and the power is transmitted to the synchronous shaft I 202 through the chain drive component 203, so that multiple chain drive components 201 operate synchronously. The picking claw connected to the chain drive component 201 performs reciprocating motion, pushing the accumulation of waste mulch film under the support frame 209.

[0049] 3. Mulch Film Transfer and Temporary Storage Stage: The movement of the picking claw pushes the accumulated mulch film above the chain drive component 201, and then these mulch films are smoothly transferred to the temporary storage box 1. The clearance groove of the temporary storage box 1 is designed to avoid conflict with the picking claw and to intercept the mulch film for temporary storage.

[0050] 4. Soil separation stage: Power is transmitted to synchronous shaft II 2062 via chain drive component 203, which in turn drives cam 2061 to rotate. The rotation of cam 2061 causes support plate 204 to vibrate, and the soil attached to the mulch film falls off through the soil leakage hole 205 of support plate 204, thereby realizing the separation of soil from mulch film.

[0051] 5. Stable Operation Guarantee Stage: Support plate 204 assists in supporting the mulch film to prevent it from detaching or becoming entangled. The specially designed support plate 204 can prevent the chain from derailing. Adjacent synchronous shafts II 2062 maintain precise synchronization with the help of chain synchronization component 207, thereby ensuring the stable operation of the vibrating component 206.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
