Description

Technical Field

[0001] This utility model relates to the field of mesh chain vibration structure technology, specifically to a mesh chain vibration structure for a blower-type residual film conveying and recycling device. Background Technology

[0002] Plastic mulching technology is widely used in my country's agricultural production as an important agricultural cultivation method. This technology not only effectively increases soil temperature, retains soil moisture, and maintains soil structure, but also prevents pests and diseases, thus significantly promoting crop growth. However, the plastic film residue left in the soil after mulching is difficult to degrade naturally, and long-term accumulation will cause serious pollution to the soil environment, and may even affect human health through the food chain. Therefore, the recycling and disposal of residual plastic film in the field has become a key link in the sustainable development of agriculture.

[0003] Currently, most common residual film recovery devices employ pneumatic separation technology. This involves using rotary tillers to pulverize the soil, followed by airflow to separate and collect the lightweight residual film. However, in practice, factors such as soil moisture, compaction, or high stone content often prevent the rotary tillers from completely pulverizing the soil, resulting in some soil clods still containing residual film. These clods, due to their weight, are difficult to be effectively blown into the collection device during transport, thus reducing the film recovery rate. Furthermore, in areas with high stone content, the stones mixed in with the soil can adversely affect the operational stability and lifespan of the recovery device. Therefore, improvements to existing technologies are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a mesh chain vibration structure for a blower-type residual film conveying and recycling device, which solves the problem that soil compaction is easily left inside after the soil is broken by rotary tillage blades, affecting recycling.

[0006] Preferably, the vibrating roller contacts the recycling net chain, the protruding strip contacts the groove of the recycling net chain, the vibrating shaft is slidably connected to the vibrating box, and the vibrating shaft can compact the soil clods through the rotating vibrating roller during vibration.

[0009] Preferably, one end of the support spring is fixedly connected to the vibrating plate, and the other end of the support spring is fixedly connected to the vibration frame, so that the support spring can support the vibrating plate.

The vibrating rollers and other structures can force secondary crushing of incompletely crushed soil clods, releasing the residual film encased within and protecting the core components of the equipment.

The entire machine not only solves the problems of low efficiency and easy damage of traditional pneumatic recycling machines in soil residue and rocky areas, but also improves the overall reliability and adaptability of the equipment, providing efficient and stable technical equipment for the treatment of agricultural film residue pollution.

[0022] Please see Figure 1-4 The vibrating roller 5 contacts the recycling net chain 2, the protruding strip 6 contacts the groove of the recycling net chain 2, the vibrating shaft 4 is slidably connected to the vibrating box 8, and the vibrating shaft 4 can crush the soil clods through the rotating vibrating roller 5 during the vibration process. The vibrating frame 9 is slidably connected to the hole of the vibrating plate 7, and the adjusting plate 12 is slidably connected to the vibrating box 8. The adjusting plate 12 can adjust the elastic force value of the vibrating spring 11. One end of the vibrating spring 11 is fixedly connected to the vibrating plate 7, and the other end of the vibrating spring 11 is fixedly connected to the adjusting plate 12. The vibrating spring 11 can drive the vibrating plate 7 and the vibrating shaft 4 to vibrate through the elastic force.

[0023] Please see Figure 1-4One end of the support spring 10 is fixedly connected to the vibrating plate 7, and the other end of the support spring 10 is fixedly connected to the vibrating frame 9. The support spring 10 can support the vibrating plate 7. Two guide rods 15 are fixedly connected inside the vibration box 8, which are symmetrically distributed vertically. The guide rods 15 are slidably connected to the adjusting plate 12. A central frame 17 is fixedly installed in the middle of the inner wall of the vibration box 8. The guide rods 15 are fixedly connected to the central frame 17. The guide rods 15 can guide the movement of the adjusting plate 12. The central frame 17 is connected to the positive and negative screws 14 through bearings. The central frame 17 is connected to the internal threaded sleeve 13 through threads.

[0024] The specific implementation process of this utility model is as follows: During the conveying process of the recycling net chain 2, the incompletely crushed soil clods enter between the vibrating roller 5 and the recycling net chain 2 under the drive of the net chain. Since the vibrating roller 5 is mounted on the vibrating shaft 4 through the bearing, and the outer surface of the vibrating roller 5 is provided with a protruding strip 6 that meshes with the groove of the net chain, the movement of the net chain drives the vibrating roller 5 to rotate through friction and meshing. At the same time, the squeezing action of the soil clods on the vibrating roller 5 causes the vibrating roller 5 and the vibrating shaft 4 to be displaced along the sliding direction of the vibrating box 8. Then, the vibration plate 7 compresses the vibration spring 11 to achieve vibration excitation. The vibration spring 11 can drive the vibrating roller 5 to squeeze the outside of the soil clods through the elastic force, so that the soil clods can be crushed. After crushing, the vibrating roller 5 can hit the outside of the recycling net chain 2, so that the recycling net chain 2 can screen the crushed fine soil, thus facilitating subsequent pneumatic recycling.

[0025] When it is necessary to change the vibration intensity, the operator rotates the forward and reverse screws 14 using a tool. The rotation of the screws drives the two internal threaded sleeves 13 and the adjusting plate 12 fixed thereto to move synchronously in opposite directions along the guide rod 15. The movement of the adjusting plate 12 changes the initial compression and preload of the vibration spring 11. The greater the preload, the stronger the excitation force generated by the vibration spring 11 driving the vibration plate 7 and vibration shaft 4, and the greater the vibration amplitude transmitted to the mesh chain. Conversely, the smaller the preload, the smaller the vibration amplitude. The support spring 10 plays a role in assisting in reset and stabilizing the vibration.
