Description

Technical Field

[0001] This application relates to the technical field of agricultural equipment, and more particularly to a mulching device for agricultural planting. Background Technology

[0002] As a key component of agriculture, crop cultivation is a social production field that utilizes the life activities of plants to obtain food, by-products, feed, and industrial raw materials through artificial cultivation. It encompasses the cultivation of various crops, trees, fruit trees, medicinal plants, and ornamental plants. In agricultural planting, mulching is a commonly used technique that has many advantages, such as increasing soil temperature, retaining soil moisture, and maintaining soil structure, and can effectively promote plant growth and development.

[0003] The agricultural mulching devices in related technologies have certain limitations. After the mulching is completed, it is usually necessary to perform a separate perforation operation. This is because although mulching has many advantages, it can also cause some problems, such as hindering the exchange of gases between the soil and the outside world, affecting the proper infiltration and drainage of water, making it difficult for plant stems and leaves to emerge, and affecting the regulation of temperature and humidity inside the film.

[0004] However, the existing method of punching holes after mulching requires additional manpower and time, increasing labor intensity and costs. Moreover, if specialized punching equipment is used, it will increase the cost of equipment purchase and maintenance, as well as the fuel or electricity costs required for equipment operation. In addition, the method of mulching first and then punching holes increases the procedures and time of the planting process. This cumbersome operation process will lead to a longer planting cycle, which may cause the best planting and growth time to be missed, and will have an adverse impact on the growth and development of crops and the final yield. Summary of the Invention

Detailed Implementation

[0022] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0023] The following description, in conjunction with the accompanying drawings, describes a mulching device for agricultural planting according to an embodiment of this application.

[0024] The mulching device for agricultural planting provided in this application embodiment can be applied in agricultural planting. It is used to quickly punch holes after mulching, which improves work efficiency. After punching the holes, the soil around the holes is compacted to prevent them from collapsing and blocking the planting holes, which facilitates subsequent sowing operations.

[0025] like Figure 1-8 As shown, the mulching device for agricultural planting according to the embodiments of this application may include a frame 1, a mulching mechanism 2, and a punching mechanism 3.

[0026] The film coating mechanism 2 and the punching mechanism 3 are arranged sequentially from left to right on the inner side of the frame 1.

[0027] The coating mechanism 2 may include an unwinding structure 21 and an adjusting structure 22. The unwinding structure 21 is located inside the frame 1, and the adjusting structure 22 is located between the unwinding structure 21 and the punching mechanism 3. The unwinding structure 21 and the punching mechanism 3 are connected.

[0028] The punching mechanism 3 may include a punching structure and an auxiliary structure, wherein the punching structure is located inside the frame 1 and the auxiliary structure is located inside the punching structure.

[0029] Specifically, the device is connected to agricultural machinery via a traction frame through the frame 1, facilitating its movement in farmland for mulching operations. During the mulching process, the mulching mechanism 2 ensures a smoother mulch film 5 coverage, while the adjustment structure 22 allows for adjustment of the mulch film 5 coverage area according to different ridge widths, effectively improving the device's applicability. Furthermore, the punching mechanism 3 enables simultaneous punching during mulching, eliminating the need for manual punching by staff, simplifying operation and significantly improving work efficiency.

[0030] In one embodiment of this application, such as Figure 2 As shown, the unwinding structure 21 may include two mounting plates 2102, a first motor 2103, an unwinding roller 2101, a transmission mechanism 2104, and a pressure roller 2105.

[0031] Two mounting plates 2102 are fixedly connected to the top of the frame 1 and are symmetrically distributed. An unwinding roller 2101 is disposed between the two mounting plates 2102. A first motor 2103 is disposed on the surface of one of the mounting plates 2102. One end of the unwinding roller 2101 passes through the adjacent mounting plate 2102 and is fixedly connected to the output shaft of the first motor 2103. The other end of the unwinding roller 2101 passes through the other mounting plate 2102 and is fixedly connected to one end of the transmission mechanism 2104. A pressure roller 2105 is disposed at the bottom of the frame 1. One end of the pressure roller 2105 is fixedly connected to the other end of the transmission mechanism 2104.

[0032] Specifically, the mulch film 5 is wound onto the unwinding roller 2101 and the unwinding end is pulled to the bottom of the pressure roller 2105. During the movement of the frame 1, the first motor 2103 is started simultaneously to unwind the mulch film 5. During this process, the pressure roller 2105 can be driven to rotate synchronously through the transmission mechanism 2104. While the mulch film 5 is well compacted, excessive friction is not generated with the surface of the mulch film 5, which may cause the mulch film 5 to tear. The transmission mechanism 2104 is a relatively mature component in the existing technology. It consists of two transmission wheels and a transmission belt. By driving one of the transmission wheels to rotate, the other transmission wheel can be driven to rotate under the action of the transmission belt. One of the transmission wheels is fixedly connected to one end of the unwinding roller 2101, and the other transmission wheel is fixedly connected to one end of the pressure roller 2105.

[0033] In one embodiment of this application, such as Figure 2 As shown, two symmetrically distributed spiral blades 2106 are fixedly connected to the surface of the pressure roller 2105.

[0034] Specifically, during the rotation of the pressure roller 2105, the spiral blades 2106 can be driven to rotate synchronously. The edges of the spiral blades 2106 are chamfered. During the rotation of the two symmetrically arranged spiral blades 2106, the film 5 can be pulled from the middle to both sides to avoid wrinkles in the film 5 that would affect the mulching.

[0035] In one embodiment of this application, such as Figure 3 As shown, the unwinding structure 21 may also include an adjusting roller 2107, two sliders 2109, two guide rods 2108, and two springs 2110.

[0036] The frame 1 has two symmetrically distributed slide grooves on its inner side. Two sliders 2109 are slidably connected to the inner walls of the two slide grooves, and two guide rods 2108 are fixedly connected to the inner walls of the two slide grooves. The sliders 2109 are slidably connected to the surfaces of the adjacent guide rods 2108. One end of the spring 2110 is fixedly connected to the surface of the slider 2109, and the other end of the spring 2110 is fixedly connected to the inner wall of the slide groove. The adjusting roller 2107 is rotatably connected between the two sliders 2109.

[0037] Specifically, the guide rod 2108 is used to guide the slider 2109, making its movement more stable. The spring 2110 provides a thrust to the slider 2109. Thus, during the unwinding process of the mulch film 5, the thrust provided by the spring 2110 to the slider 2109 makes the adjusting roller 2107 stick tightly to the middle of the mulch film 5, ensuring the tension during the unwinding process and avoiding wrinkles caused by changes in the tension of the mulch film 5 as the unwinding operation progresses, thereby improving the mulching effect.

[0038] In one embodiment of this application, such as Figure 3 and Figure 4 As shown, the adjustment structure 22 may include a rotating shaft 2202, a screw 2204, and a guide plate 2205.

[0039] The lower end of the rotating shaft 2202 passes through the frame 1 and is fixedly connected to the top of the guide plate 2205. The middle part of the guide plate 2205 is bent toward the center of the frame 1 to form a guide part. The surface of the rotating shaft 2202 is provided with a through hole 2203. The surface of the frame 1 is provided with threaded holes 2201 that are evenly distributed and arranged in a ring around the rotating shaft 2202. The screw 2204 passes through the through hole 2203 and is threadedly connected to the inner wall of the adjacent threaded hole 2201.

[0040] Specifically, after the mulch film 5 is laid on the ground, the guide plate 2205 can guide and fold both ends of the mulch film 5 so that it is tightly attached to both sides of the mulch cage. At the same time, the guide plate 2205 can push the soil 4 to compact the mulch film 5 tightly to both sides of the mulch cage, making it more stable after covering.

[0041] In one embodiment of this application, such as Figure 5 and Figure 6 As shown, the drilling structure may include a bracket 301, a connecting plate 302, an electric push rod 304, a positioning bolt 313, and a drilling sleeve 305.

[0042] The bracket 301 is fixedly connected to the inner side of the frame 1. The bracket 301 has evenly distributed positioning holes 303 on one side and a mounting groove on the top. The connecting plate 302 is L-shaped and its inner side contacts the surface of the bracket 301. The positioning bolt 313 is set on one side of the bracket 301 and passes through the bracket 301 and is threadedly connected to the inner wall of the adjacent positioning hole 303. The electric push rod 304 is fixedly connected to the top of the connecting plate 302. The upper end of the punch sleeve 305 is fixedly connected to the bottom of the connecting plate 302, and the lower end of the punch sleeve 305 passes through the mounting groove. The output shaft of the electric push rod 304 is fixedly connected to the top of the punch sleeve 305.

[0043] Specifically, by activating the electric push rod 304, the punching sleeve 305 can be moved downwards. During this process, it can pass through the mulch film 5 and be inserted into the soil 4 to punch holes in the soil 4, which facilitates subsequent sowing operations and eliminates the need for subsequent staff to perform punching operations separately.

[0044] Furthermore, the positioning bolt 313 is used in conjunction with the positioning hole 303 to fix the position of the connecting plate 302. By adjusting the position of the connecting plate 302, the position of the punch sleeve 305 can be changed, thereby adjusting the punching position according to the actual situation to improve the applicability.

[0045] In one embodiment of this application, such as Figure 5 and Figure 6 As shown, the lower end surface of the punched sleeve 305 has a cutting bevel.

[0046] Specifically, the beveled cut allows the punch sleeve 305 to more easily pass through the mulch film 5 and insert into the soil 4 for punching operations.

[0047] In one embodiment of this application, such as Figure 5-7 As shown, the auxiliary structure may include a connecting shaft 308, a spiral conveyor plate 309, a second motor 306, a pressure block 307, and a drill bit 310.

[0048] The second motor 306 is located inside the punching sleeve 305. The upper end of the connecting shaft 308 is fixedly connected to the output shaft of the second motor 306, and the lower end of the connecting shaft 308 extends through the punching sleeve 305 and is fixedly connected to the top of the drill bit 310. The spiral conveying plate 309 is fixedly connected to the surface of the connecting shaft 308 and located inside the punching sleeve 305. The pressure block 307 is fixedly connected to the surface of the punching sleeve 305, and the pressure block 307 has a cavity inside. The cross-sectional shape of the pressure block 307 is funnel-shaped.

[0049] Specifically, during the drilling operation, starting the second motor 306 can drive the connecting shaft 308 to rotate, which in turn drives the drill bit 310 and the spiral conveyor plate 309 to rotate synchronously. This allows the drill bit 310 to break the soil 4 during the drilling process, and the spiral conveyor plate 309, in conjunction with the drilling sleeve 305, can lift the soil 4, making drilling easier and improving work efficiency. After drilling is completed, the pressure block 307 can compact the soil 4 around the hole to prevent it from collapsing and covering the drilled hole.

[0050] In one embodiment of this application, such as Figure 7-8 As shown, the surface of the punch sleeve 305 is provided with uniformly distributed discharge grooves 311 that are connected to the cavity, and the surface of the pressure block 307 is provided with uniformly distributed discharge holes 312.

[0051] See details Figure 8 The soil 4 lifted by the spiral conveyor plate 309 can form separated soil 6 and be introduced into the cavity through the discharge trough 311. Finally, it is discharged to the area around the planting hole under the action of the discharge hole 312, so as to achieve the effect of using the separated soil 6 to press the mulch film 5 around the hole, which is convenient to backfill the planting hole with the separated soil 6 after subsequent sowing.

[0052] Specifically, the working principle of this application is as follows: The principle of laying the mulch film 5: By starting the first motor 2103, the mulch film 5 can be unwound. During this process, the transmission mechanism 2104 synchronously drives the pressure roller 2105 to rotate, which can effectively compact the mulch film 5 without generating excessive friction with the surface of the mulch film 5, thus preventing the mulch film 5 from tearing. In addition, during this process, the rotation of two symmetrically arranged spiral blades 2106 can pull the mulch film 5 from the middle to both sides, avoiding wrinkles in the mulch film 5 that would affect the mulching. At the same time, during the mulching process, the spring 2110 provides a thrust to the slider 2109, which makes the adjusting roller 2107 stick tightly to the middle of the mulch film 5, ensuring the tension during the unwinding process and preventing wrinkles caused by changes in the tension of the mulch film 5 during the unwinding operation, thereby improving the mulching effect.

[0053] Drilling principle: By activating the electric push rod 304, the drilling sleeve 305 can be moved down. At the same time, the second motor 306 can be activated to drive the connecting shaft 308 to rotate, which in turn drives the drill bit 310 and the spiral conveyor plate 309 to rotate synchronously. During the drilling process, the rotation of the drill bit 310 breaks the soil 4, and the spiral conveyor plate 309, in conjunction with the drilling sleeve 305, lifts the soil 4, making drilling easier and improving work efficiency. After drilling is completed, the pressure block 307 can be used to compact the soil 4 around the hole to prevent it from collapsing and covering the drilled hole.

[0054] In summary, the mulching device for agricultural planting according to the embodiments of this application can make the mulch film laid more evenly under the action of the mulching mechanism, which is suitable for ridges of different widths. It can also prevent the mulch film from wrinkling during the laying process, thus improving the laying effect. At the same time, under the action of the perforating mechanism, the perforation operation can be carried out simultaneously during the laying process. After the perforation is completed, the soil around the perforation can be compacted by the pressure block to prevent it from collapsing and covering the perforated holes. The soil lifted by the spiral conveyor plate can form separated soil and be introduced into the cavity through the discharge trough. Finally, it is discharged to the area around the planting hole under the action of the discharge hole, realizing the effect of using the separated soil to compact the mulch film around the perforation, which is convenient for backfilling into the planting hole after subsequent sowing.
