Technical Field
[0001] This utility model belongs to the field of vegetable film pressing technology, specifically a vegetable planting film pressing device. Background Technology
[0002] The vegetable planting mulch film pressing device is a modern agricultural machinery equipment designed specifically for large-scale vegetable planting. It is used to efficiently complete the automated laying and compaction of mulch film. The device adopts a modular design, which can be adapted to various farming environments and significantly improves the efficiency of mulch film laying. Its core function is to ensure that the mulch film is flat and adheres to the ground by precisely controlling the tension of the mulch film and the pressure of the soil covering. This effectively maintains soil moisture, regulates soil temperature, and inhibits weed growth, creating the best growing environment for vegetable crops and meeting the agronomic needs of different vegetable varieties.
[0003] In existing technologies, vegetable processing typically involves film pressing, which requires mechanical equipment. Film pressing devices are commonly used for this process and have a wide range of applications. These devices typically involve spreading a thin film for covering, followed by pressing with film-spreading rollers. A typical setup consists of a frame, hydraulic lifting rod, large swing arm, chain box, suspension bracket, pressing rollers, lifting blades, and film-spreading rollers. The hydraulic lifting rod drives the top rod and swing arm, which operate synchronously with the frame, pressing the film onto the spreading rollers. The two sets of film-spreading rollers at the bottom cooperate with the pressing rollers below, rotating to complete the film pressing process on the vegetable surface. Simultaneously, pressing rollers on both sides compact the film, thus completing the vegetable processing.
[0004] In current technology, vegetable film pressing devices on the market typically operate using a hydraulic lifting rod installed on the top side. The hydraulic lifting rod drives the top rod swing arm, which operates synchronously with the frame to press the film onto the spreading rollers. This is achieved through the cooperation of the pressing rollers below, with two sets of spreading rollers at the bottom rotating to complete the film pressing operation on the vegetable surface. Simultaneously, the pressing rollers installed on both sides compact the film. However, during the vegetable film pressing process, protrusions on the soil surface often exist, which can tear the film during the pressing operation, requiring secondary operations, which is cumbersome and wastes machine capacity, affecting work efficiency. Therefore, to address the above problems, a vegetable planting film pressing device is proposed. Utility Model Content

A positioning seat 39 is installed at the end of the base frame connector 38. A frame 20 is installed at the other end of the positioning seat 39.
[0017] In current technology, vegetable film pressing devices on the market typically operate using a hydraulic lifting rod 3 mounted on the top side. The hydraulic lifting rod 3 drives the top rod swing arm 22, which is connected to the frame 20 and operates synchronously, thereby pressing the film spreading roller 27. This is achieved through the cooperation of the film pressing wheel 13 below, with the two sets of film spreading rollers 27 at the bottom rotating to complete the film pressing operation on the vegetable surface. At the same time, the film pressing wheels 13 mounted on both sides compact the film. However, during the vegetable film pressing process, protrusions on the soil surface are often encountered, which can tear the film during the pressing operation, requiring secondary operations, which is cumbersome and wastes machine capacity, affecting work efficiency. Therefore, to address the above problems, a vegetable planting film pressing device is proposed. During vegetable film pressing operations, it is connected to a motor vehicle via an adapter 17. The motor vehicle drives the entire film pressing device to move, with the bottom wheel 14 rotating in coordination, and the rotary tillage shaft 40 rotating simultaneously to complete the basic transmission operation.

The entire mulching device is moved by a motor vehicle. During the mulching operation, after the film spreading roller 27 mulches the vegetables, the pressing rollers 13 on both sides press the edges firmly, while the lifting knives 15 on both sides turn the soil over, thus completing the overall vegetable mulching operation.
[0020] Working principle: In current technology, vegetable film pressing devices on the market typically operate using a hydraulic lifting rod 3 mounted on the top side. The hydraulic lifting rod 3 drives the top rod swing arm 22, which is connected to the frame 20 and operates synchronously, thereby pressing the film spreading roller 27. This is achieved through the cooperation of the pressing rollers 13 below. The two sets of film spreading rollers 27 at the bottom rotate to complete the film pressing operation on the vegetable surface. Simultaneously, the pressing rollers 13 mounted on both sides compact the film. However, during the vegetable film pressing process, protrusions on the soil surface often exist, which can tear the film during pressing, requiring secondary operations, which is cumbersome. This results in wasted machine capacity and affects production efficiency. To address the aforementioned issues and improve efficiency, a vegetable planting film-pressing device is proposed. During film-pressing operations, the device connects to a motor vehicle via an adapter 17. The vehicle then moves the entire film-pressing device, with the bottom wheel 14 rotating in coordination. Simultaneously, the rotary tiller shaft 40 rotates, completing the basic transmission operation. During film-pressing, commercially available film rolls are installed at the ends of the film-spreading roller 27 and the second film-spreading roller 28. The motor vehicle then moves the entire film-pressing device. During film-pressing, after the film-spreading roller 27 presses the film onto the vegetables, the pressing rollers 13 on both sides compact the edges, while the plowshares 15 on both sides turn over the soil, thus completing the overall vegetable film-pressing operation.
