Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a special equipment for biomass straw mulching. Background Technology

[0002] In the development and utilization of biomass energy, crop straw, as an important renewable resource, is particularly important for its storage and protection. After harvesting, crop straw often needs to be piled up to form straw stacks for subsequent processing or long-term storage. However, because straw itself contains a certain amount of moisture and nutrients, if exposed to the natural environment for a long time, it is easily affected by rainwater erosion, wind, sun, and other factors, leading to a decline in straw quality, or even mold and deterioration, thus losing its value as a biomass energy source.

[0003] To address this issue, covering straw stacks for protection has become a common practice. Traditional covering methods often involve manually laying plastic film. While this method can prevent rainwater erosion and reduce the impact of wind and sun to some extent, manual laying of plastic film is not only labor-intensive but also inefficient, making it difficult to meet the needs of large-scale straw storage. Secondly, due to the height limitations of straw stacks, it is difficult to ensure that the plastic film completely covers the top of the stack during manual laying, resulting in poor covering effects and leaving the risk of rainwater seepage. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a special equipment for biomass straw mulching, which solves the problems that existing manual plastic film laying is not only labor-intensive, but also difficult to ensure that the plastic film covers the top of the stack, thus affecting the mulching effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a special equipment for biomass straw mulching, comprising a vertical frame, the vertical frame consisting of two vertical poles and a horizontal bar welded to the top of the two vertical poles, a base frame welded to the bottom of the horizontal bar, a support wheel installed at the bottom of the base frame, and rope lifting assemblies installed opposite each other on the left and right sides of the top of the horizontal bar, the rope lifting assembly being a movable pulley rope structure consisting of a fixed pulley, a rope, and a movable pulley, with a hook for attaching one end of the rope installed on the pulley seat of the movable pulley.

[0006] The beneficial effects of this utility model are as follows: after the plastic film roll is mounted on a round rod, the round rod is then tied to the bottom of the rope lifting assembly. The plastic film can be lifted to the top of the straw stack safely and effortlessly by the rope lifting assembly. This allows the device to safely and effortlessly release the film as it moves along the straw stack, flexibly covering straw stacks of any shape.

[0007] To ensure the stability of the device's movement;

[0008] As a further improvement to the above technical solution: the base frame is a welded square frame structure, and the support wheels are installed at the four corners of the bottom of the base frame.

[0009] The beneficial effects of this improvement are: the base frame and the multiple support wheels installed at the corners of the base frame can provide stable support for the taller vertical frame, ensuring the stability and safety of the device.

[0010] In order to effectively ensure the structural strength of the vertical frame;

[0011] As a further improvement to the above technical solution: an inclined brace is welded between the vertical bar and the horizontal bar.

[0012] The beneficial effects of this improvement are: the second diagonal brace can support the crossbar and improve the structural strength of the crossbar.

[0013] To further improve the structural stability of the vertical frame;

[0014] As a further improvement to the above technical solution: a diagonal brace is welded at an angle between the vertical rod and the base frame.

[0015] The beneficial effects of this improvement are: the diagonal brace can effectively improve the structural stability of the vertical frame on the base frame.

[0016] To ensure the safe use of the rope lifting assembly;

[0017] As a further improvement to the above technical solution: the pulley seat of the fixed pulley is welded to the crossbar, and one end of the rope is attached to a hook at the bottom of the pulley seat of the fixed pulley.

[0018] The beneficial effect of this improvement is that the fixed pulley can be stably installed on the crossbar, providing a solid support for the entire rope lifting assembly.

[0019] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0025] Example 1:

[0026] like Figure 1 As shown in Figure 3: A special device for biomass straw mulching includes a vertical frame 3, which consists of two vertical rods 31 and a horizontal rod 33 welded to the top of the two vertical rods 31. A base frame 1 is welded to the bottom of the horizontal rod 33, and a support wheel 2 is installed at the bottom of the base frame 1. Rope lifting components 4 are installed on the left and right sides of the top of the horizontal rod 33. The rope lifting component 4 is a movable pulley rope structure composed of a fixed pulley 41, a rope 42, and a movable pulley 43. A hook 2 45 for attaching one end of the rope is installed on the pulley seat of the movable pulley 43. After the plastic film roll is fitted onto a round rod, the round rod is then attached to the bottom of the rope lifting component 4. The plastic film can then be safely and effortlessly lifted to the top of the straw stack by the rope lifting component 4. This allows the device to safely and effortlessly lay the film while moving along the straw stack, flexibly covering straw stacks of any shape. The base frame 1 is a welded square frame structure. The support wheels 2 are installed at the four corners of the bottom of the base frame 1. The base frame 1 and the multiple support wheels 2 installed at the corners of the base frame 1 can provide stable support for the tall vertical frame 3, ensuring the stability and safety of the device. The vertical rod 31 and the horizontal rod 33 are welded together with inclined bracing rod 2 34, which can support the horizontal rod 33 and improve the structural strength of the horizontal rod 33. The vertical rod 31 and the base frame 1 are welded together with inclined bracing rod 1 32, which can effectively improve the structural stability of the vertical frame 3 on the base frame 1. The pulley seat of the fixed pulley 41 is welded to the horizontal rod 33. One end of the rope 42 is attached to the hook 1 44 set at the bottom of the pulley seat of the fixed pulley 41. The fixed pulley 41 can be stably installed on the horizontal rod 33, providing stable support for the entire rope lifting assembly 4.

[0027] The working principle of this technical solution is as follows: Place the movable pulley 43 at a low position, then tie one end of the rope to hook 45. Insert a round rod of appropriate length into the rolled-up finished plastic film. Securely tie the other ends of the ropes connected to the two rope lifting components 4 to both ends of the round rod. Pull the rope 42 downwards, allowing the rope lifting components 4 to act as a movable pulley group, moving the plastic film effortlessly to the upper side of the vertical frame 3. During the raising of the plastic film, to facilitate subsequent laying, one person can hold one end of the film extending from the plastic film. After the plastic film is raised, tie the rope 42 to the hanging rod 5. Finally, the operator pushes the entire device to one side of the straw stack with the support of the support wheel 2, pressing down one end of the lowered film, and then slowly pushes the device to the other side of the straw stack. While the device is moving, the film is laid out, thus completing the safe and effortless film covering work.
