Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an adjustable pressure agricultural press. Background Technology
[0002] An agricultural roller is a type of agricultural machinery specifically designed for compacting farmland soil. It uses its own weight or an attached compaction mechanism to evenly and moderately compact the soil. This compaction effectively improves soil structure, increases soil density, and makes soil particles more tightly bound together. This process helps promote deeper root development in crops and enhances their resistance to wind and lodging. Simultaneously, compaction enhances the soil's water and fertilizer retention capacity, reducing water and nutrient loss and providing a more stable and favorable soil environment for crop growth. Agricultural rollers are an indispensable piece of machinery in modern agricultural production, playing a vital role in improving crop yield and quality.
[0003] When using a rolling press, different pressures are required for different soil types and different crops. However, considering that the rolling rollers on traditional rolling presses are in a one-piece structure, it is not convenient to adjust the weight of the rolling press, and therefore it is impossible to adjust the pressure of the rolling rollers, which is extremely inconvenient. Therefore, there is an urgent need for an agricultural rolling press with adjustable pressure to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide an agricultural press with adjustable pressure, which solves the problem that in the prior art, the press roller is located in an integrated structure, making it inconvenient to adjust the weight of the press and thus unable to adjust the pressure of the press roller.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An adjustable pressure agricultural press includes a frame, an inner frame slidably connected to the inner side of the frame, and a hydraulic cylinder fixedly connected to the top of the frame by bolts. The output shaft of the hydraulic cylinder passes through the top of the frame and the inner frame. A bearing rod is rotatably connected to the inner side of the inner frame, and several sleeves are sleeved on the bearing rod. The diameter of all the sleeves is distributed from large to small from the inside to the outside. A valve body is installed on one side of each sleeve. A scraper is fixedly connected to one side of the inner frame.
[0007] Preferably, sliders are fixedly connected to both sides of the inner frame, and both sliders are slidably connected to the inner wall of the frame through a groove.
[0008] Preferably, the frame and the inner frame are provided with side grooves on the side closest to all the valve bodies.
[0009] Preferably, a top frame is fixedly connected to the top of the frame, and a mounting plate is fixedly connected to one side of the top of the top frame.
[0010] Preferably, the scraper is located on one side of the outermost one of all the sleeves.
[0011] Preferably, the slider and the groove are in clearance fit.
[0012] This utility model has the following beneficial effects:
[0013] This invention effectively solves the problem of non-adjustable pressure in traditional compaction presses. Traditional compaction presses typically use a one-piece structure for the compaction roller, making it difficult to adjust the weight of the press and thus limiting the flexibility of pressure adjustment. This technical solution, however, achieves precise pressure control by designing a sliding inner frame and an adjustable weight sleeve. The introduction of a hydraulic cylinder allows operators to easily control the up-and-down movement of the inner frame, thereby adjusting the contact distance between the compaction roller and the soil, and achieving precise control of the compaction depth. This design not only improves the flexibility of compaction operations but also avoids damage to the soil and crops caused by improper compaction depth. Furthermore, the coordinated design of the sleeve and valve body allows operators to flexibly adjust the weight of the compaction roller according to actual needs. This adjustable design not only adapts to different soil conditions and crop planting requirements but also improves the applicability and practicality of the compaction press. By adjusting the weight of the sleeve, different degrees of soil compaction can be achieved, thereby improving soil structure, increasing soil compaction, promoting crop root development, enhancing crop resistance to wind and lodging, and improving soil water and fertilizer retention capacity. Furthermore, the scraper design effectively solves the problem of soil adhering to the compaction roller during operation. The scraper moves with the inner frame to promptly clean the soil adhering to the compaction roller, keeping it clean and smooth, ensuring smooth compaction operations and consistent work quality. This invention boasts multiple advantages, including a reasonable structural design, simple operation, adjustable pressure, and strong applicability. It not only solves the problem of non-adjustable pressure in traditional compaction machines but also improves the flexibility and practicality of compaction operations. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0022] Reference Figure 1-5 An adjustable pressure agricultural roller includes a frame 1, with an inner frame 5 slidably connected to the inner side of the frame 1. The inner frame 5 is slidably connected to the inner side of the frame 1 and slides up and down within the frame 1 driven by a hydraulic cylinder 4, thereby adjusting the contact distance between the roller and the soil and achieving precise control of the compaction depth. The top of the frame 1 is fixedly connected to the hydraulic cylinder 4 by bolts. The output shaft of the hydraulic cylinder 4 passes through the top of the frame 1 and the inner frame 5. A bearing rod 6 is rotatably connected to the inner side of the inner frame 5, and several sleeves 7 are sleeved on the bearing rod 6. The diameters of the sleeves 7 are distributed from the inside to the outside in descending order, forming a roller. The weight of the pressing roller can be changed by adjusting the water volume inside the sleeve 7, thereby regulating the pressure of the pressing machine. The diameters of all sleeves 7 decrease sequentially from the inside to the outside. A valve body 11 is installed on one side of each sleeve 7 to control the entry and exit of materials inside the sleeve 7. By opening or closing the valve body 11, the water volume inside the sleeve 7 can be adjusted, thus changing the weight of the pressing roller. A scraper 12 is fixedly connected to one side of the inner frame 5 and moves with the inner frame 5. During the pressing operation, the scraper 12 can clean the soil adhering to the surface of the outermost sleeve 7 on the pressing roller, keeping the pressing roller clean and smooth, and ensuring the smooth progress of the pressing operation.
[0023] Furthermore, sliders 9 are fixedly connected to both sides of the inner frame 5, and both sliders 9 are slidably connected to the inner wall of the frame 1 through the slide groove 10. When the hydraulic cylinder 4 drives the inner frame 5 to slide up and down inside the frame 1, the sliders 9 slide along the trajectory of the slide groove 10, providing stable guidance and support for the inner frame 5, making the inner frame 5 more stable during the sliding process, reducing the resistance caused by friction, improving the working efficiency of the hydraulic cylinder 4, and also extending the service life of the equipment.
[0024] Furthermore, the frame 1 and the inner frame 5 are provided with side grooves 8 on the side near all the valve bodies 11. When it is necessary to operate the valve body 11, the operator can easily contact the valve body 11 through the side grooves 8 to open or close it. The design of the side grooves 8 improves the convenience of operation, enabling the operator to quickly and accurately adjust the weight of the sleeve 7, thereby achieving precise control of the pressure of the press.
[0025] Furthermore, a top frame 2 is fixedly connected to the top of the frame 1, and a mounting plate 3 is fixedly connected to one side of the top of the top frame 2. When installing the agricultural press, the frame 1 can be stably fixed to the driving equipment such as the tractor through the mounting plate 3. The design of the top frame 2 and the mounting plate 3 provides additional support and fixing points, making the agricultural press more stable during operation and reducing the risk of falling off due to vibration or external force.
[0026] Furthermore, the scraper 12 is located on one side of the outermost one of all the sleeves 7. The position design of the scraper 12 ensures that it can effectively clean the soil on the press roller, avoid the impact of soil accumulation on the working efficiency, and at the same time keep the press roller smooth and clean, extending its service life.
[0027] Furthermore, the slider 9 and the groove 10 are in clearance fit.
[0028] In summary:
[0029] First, fill all the sleeves 7 with water for later adjustment of the press roller weight. Then, install the frame 1 to the drive equipment such as a tractor using bolts, ensuring that the agricultural press is stably connected to the drive equipment for movement and operation in the field. During installation, the additional supports and fixing points provided by the top frame 2 and mounting plate 3 are used to firmly fix the frame 1 to the drive equipment, reducing the risk of it falling off due to vibration or external forces.
[0030] After installation, the operator can activate the hydraulic cylinder 4. The output shaft of the hydraulic cylinder 4 passes through the top of the frame 1 and is connected to the inner frame 5. Through the extension and retraction of the hydraulic cylinder 4, the inner frame 5 can slide up and down inside the frame 1. During this process, the slider 9 slides along the trajectory of the slide groove 10, providing stable guidance and support for the inner frame 5, making the inner frame 5 smoother during sliding, reducing the resistance caused by friction, improving the working efficiency of the hydraulic cylinder 4, and extending the service life of the equipment. By controlling the extension and retraction of the hydraulic cylinder 4, the operator can flexibly control the position of the inner frame 5, and thus control the contact distance between the pressing roller composed of all the sleeves 7 and the soil, achieving precise control of the pressing depth. While adjusting the pressing depth, the operator can also adjust the weight of the pressing roller. Specifically, a valve body 11 is installed on one side of each sleeve 7. When it is necessary to adjust the weight of the sleeve 7, the operator can easily access the valve body 11 through the side groove 8 to open or close it. By opening or closing these valve bodies 11, a certain amount of water can be discharged from the sleeve 7, thereby changing the weight of the sleeve 7. When it is necessary to increase the pressure of the press roller, the valve body 11 of the corresponding sleeve 7 can be opened to fill the sleeve 7 with material; conversely, when it is necessary to decrease the pressure, the valve body 11 can be opened to discharge the material from the sleeve 7. This design allows operators to flexibly adjust the weight of the press roller according to soil conditions and crop planting needs, achieving precise control of the press roller pressure. In addition, a scraper 12 is fixedly connected to one side of the inner frame 5. The scraper 12 is located on one side of the outermost one of all the sleeves 7. During the pressing operation, the scraper 12 can move with the inner frame 5 to clean the soil adhering to the press roller, keeping the press roller clean and smooth, avoiding the impact of soil accumulation on work efficiency, and also extending the service life of the press roller. Through the cooperative design of the hydraulic cylinder 4, slider 9, and groove 10, precise control of the pressing depth is achieved, improving the flexibility and accuracy of the operation. The coordinated design of valve body 11 and sleeve 7 enables flexible adjustment of the weight of the press roller, meeting the pressing pressure requirements of different soil conditions and crop planting needs. The side groove 8 design improves operational convenience, allowing operators to quickly and accurately adjust the weight of sleeve 7. The design of top frame 2 and mounting plate 3 provides additional support and fixing points, enhancing the connection stability between the agricultural press and the drive equipment and reducing the risk of detachment due to vibration or external forces. The positional design of scraper 12 ensures effective cleaning of soil from the press roller, maintaining its cleanliness and smoothness, extending its service life, and improving operational efficiency.
