Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and more specifically, to a portable mulching device for crop mulching in mountainous areas. Background Technology

[0002] Agricultural mulching is a widely used agronomic technique in crop cultivation. By covering the soil surface with a plastic film, it effectively retains soil moisture, increases soil temperature, and inhibits weed growth, thereby improving crop yield and quality. Especially in complex terrain conditions such as mountainous areas, mulching technology is of great significance for improving agricultural production conditions and promoting sustainable agricultural development.

[0003] Common mulching equipment consists of large machinery or simple manual tools. The former is bulky, complex to operate, and expensive, making it difficult to meet the needs of small plots in mountainous areas. The latter, although simple in structure, often suffers from uneven film tension, poor mulching flatness, and high labor intensity, failing to meet the requirements of efficient and stable mulching operations. In addition, existing equipment is prone to sinking and slipping on soft or uneven ground, affecting the continuity of operations and the quality of mulching. Therefore, we propose a portable mulching device for crops in mountainous areas to solve the above-mentioned problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a portable mulching device for crops in mountainous areas. It utilizes a combination of a forward and reverse threaded drive rod and a drive block structure to enable the insertion rod to quickly tension the film roll and simultaneously adjust the distance between the push wheel and the flattening wheel, adapting to different terrains and operational needs. This simplifies the complex assembly process of traditional mulching equipment. Furthermore, the push plate pre-levels the ground surface, and the push wheel, aided by a V-shaped anti-sinking strip, moves stably in soft soil, preventing the equipment from sinking. The flattening wheel, through the sliding engagement of the connecting rod, ensures uniform compaction of the film, improving mulching quality. This significantly enhances the portability and operational flexibility of the equipment.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A portable mulching device for crops in mountainous areas includes a base and a film. A push plate is fixedly connected to the bottom of the base, and the push plate is trapezoidal in shape. An adjustment mechanism is movably connected to the top of the base via a bearing. The film is movably connected to the inner side of the film, and both ends of the adjustment mechanism are movably connected to a connecting frame via a rotating shaft. A stabilizing rod is fixedly connected to the opposite side of the connecting frame away from the adjustment mechanism. One end of the stabilizing rod passes through the connecting frame and is fixedly connected to a push rod.

[0009] Furthermore, the control mechanism includes a drive rod, the middle position of which is movably connected to the middle position of the base via a rotating shaft, and a set of left-right symmetrical positive and negative threads are opened on the outer side of the drive rod. The two ends of the drive rod are respectively movably connected to the opposite sides of the connecting frame via rotating shafts.

[0010] Furthermore, one end of the drive rod passes through the connecting frame and is fixedly connected to an adjustment handle. The outer side of the drive rod is movably connected to a drive block via positive and negative threads, and the drive block is cylindrical.

[0011] Furthermore, each of the drive blocks is rotatably connected to a push wheel, and the push wheel is fixedly connected to an anti-sinking strip in a circular array on its outer side, with the anti-sinking strip being arranged in a V-shape.

[0012] Furthermore, each of the drive blocks is fixedly connected to a support bar, and the support bars are arranged symmetrically. The opposite sides of the support bars are fixedly connected to insert rods, which are respectively inserted into the two ends of the membrane.

[0013] Furthermore, each of the drive blocks is fixedly connected to an extension arm, and the extension arms are symmetrically arranged. Each of the opposite sides of the extension arms is movably connected to a flattening wheel via a rotating shaft.

[0014] Furthermore, a connecting rod is provided on the opposite side of the flattening wheel, and both ends of the connecting rod are slidably connected to the opposite side of the flattening wheel. The end of the film away from the insertion rod is close to and passes through the bottom of the flattening wheel.

[0015] 3. Beneficial Effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this solution, the positive and negative thread drive rods are combined with the drive block structure to enable the insertion rod to quickly tension the film roll and simultaneously adjust the distance between the push wheel and the flattening wheel to adapt to different terrains and operational needs. This simplifies the complex assembly process of traditional film covering equipment. Secondly, the push plate pre-levels the ground surface, and the push wheel moves stably in the soft soil with the help of the V-shaped anti-sinking strip to prevent the equipment from sinking. The flattening wheel ensures that the film is evenly compacted through the sliding cooperation of the connecting rod, thereby improving the film covering quality and significantly enhancing the portability and operational flexibility of the equipment.

[0018] (2) This solution can achieve multi-functional integrated operation of film tensioning, wheel spacing adjustment and film compaction by adjusting the throttle. It not only optimizes the operation process, but also enhances the versatility and reliability of the equipment under different soil conditions. It provides a practical and efficient solution for agricultural mechanization in mountainous areas. Secondly, the entire equipment is easy to operate and does not require an additional power source. It is especially suitable for single-person operation in complex mountainous terrain, which greatly reduces labor intensity and improves film covering efficiency and adaptability.

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Example 1:

[0027] Please see Figures 1-4A portable mulching device for crop mulching in mountainous areas includes a base 1 and a film 2. A push plate 3 is fixedly connected to the bottom of the base 1, and the push plate 3 is trapezoidal. An adjustment mechanism 4 is movably connected to the top of the base 1 via a bearing. The film 2 is movably connected to the inner side of the film 2. Both ends of the adjustment mechanism 4 are movably connected to a connecting frame 5 via a rotating shaft. A stabilizing rod 6 is fixedly connected to the opposite side of the end of the connecting frame 5 away from the adjustment mechanism 4. One end of the stabilizing rod 6 passes through the connecting frame 5 and is fixedly connected to a push rod 7.

[0028] Example 2:

[0029] In view of the above embodiment 1, further description is provided, see reference. Figure 2 , Figure 3 and Figure 4 The control mechanism 4 includes a drive rod 401. The middle position of the drive rod 401 is movably connected to the middle position of the base 1 via a rotating shaft. A set of symmetrical positive and negative threads are opened on the outer side of the drive rod 401. The two ends of the drive rod 401 are movably connected to the opposite sides of the connecting frame 5 via rotating shafts. One end of the drive rod 401 passes through the connecting frame 5 and is fixedly connected to the control handle 402. The outer side of the drive rod 401 is movably connected to the drive block 403 via positive and negative threads. The drive block 403 is cylindrical. The outer side of the drive block 403 is rotatably connected to the push wheel 404. The outer side of the push wheel 404 is fixedly connected to the anti-sinking strip 405 in a ring array. The anti-sinking strip 405 is V-shaped.

[0030] The drive block 403 moves symmetrically along the rod body via the positive and negative thread structure of the drive rod 401, thereby achieving synchronous adjustment of the support components on both sides. This ensures uniform tension and stable compaction of the film during the film covering operation. The push wheel 404 and V-shaped anti-slip strip 405, which are rotatably connected to the outside of the drive block 403, effectively enhance the equipment's passability and anti-slip properties on soft or complex ground, preventing the equipment from sinking into the mud during operation and ensuring the continuity and stability of the film covering operation.

[0031] Example 3:

[0032] In view of the above embodiments 1 and 2, further description is provided, please refer to... Figure 2 and Figure 4 Support bars 8 are fixedly connected to the outer side of the drive block 403, and the support bars 8 are symmetrically arranged. Insert rods 9 are fixedly connected to the opposite side of the support bars 8. The insert rods 9 are respectively inserted into the two ends of the film 2. Extension arms 10 are fixedly connected to the outer side of the drive block 403, and the extension arms 10 are symmetrically arranged. Flattening wheels 11 are movably connected to the opposite side of the extension arms 10 through a rotating shaft. Connecting rods 12 are provided on the opposite side of the flattening wheels 11, and the two ends of the connecting rods 12 are slidably connected to the opposite side of the flattening wheels 11. The end of the film 2 away from the insert rods 9 is close to and passes through the bottom of the flattening wheels 11.

[0033] Through the linkage design of the drive block 403 with the support bar 8, the insertion rod 9, the extension arm 10 and the flattening wheel 11, the synchronous control of film tensioning and compaction is realized, which significantly improves the flatness and consistency of the film covering operation. The insertion rod 9 effectively prevents the film from shifting or loosening during the operation, and the sliding connection mechanism of the flattening wheel 11 ensures uniform pressure and adapts to different terrains and soil conditions.

[0034] Based on the above embodiments 1, 2, and 3, the working principle is further described. In use, the two insert rods 9 are respectively inserted into the shafts of the two ends of the film 2. Rotating the control handle 402 causes the drive rod 401 to rotate. The drive rod 401, through its positive and negative threads, drives two drive blocks 403 to slide to opposite sides. The drive blocks 403 push the support bar 8, causing the insert rods 9 to move towards each other until the support bar 8 drives the two ends of the film 2 to approach each other and become tensioned. During this process, the extension arm 10 connected to the drive block 403 drives the pressure... The flat roller 11 moves synchronously, and the pressing roller 11 slides along the outside of the connecting rod 12 to maintain stability. The movement of the drive block 403 also drives the push rollers 404 to move closer to each other, adjusting their spacing to meet the operational requirements. One end of the film 2 passes through the bottom of the pressing roller 11 and is initially pressed onto the surface of the land to be covered. The operator pushes the equipment forward as a whole through the push rod 7. The push roller 404 moves smoothly in the trench with the help of the anti-sinking strip 405. During this process, the push plate 3 flattens the higher soil, and the pressing roller 11 then evenly presses the film 2 onto the ground to complete the film covering operation.

[0035] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
