Description

Technical Field

[0001] The invention relates to the technical field of ground films, and in particular to a high-strength and easily recyclable ground film and a preparation method thereof. Background Art

[0002] Film mulching is a mature agricultural cultivation technology. It can conserve water, fertilizer and humidity, effectively increase and prolong the growing period of crops, and ensure the increase of crop yields. With the continuous development of agricultural modernization, the use of film mulching in rural areas has become an important means to ensure high and stable agricultural yields. However, before the film is made, it is necessary to recycle the film and re-make new film to reduce resource waste. However, at present, agricultural film is widely used by manual and mechanical film laying. However, the recycling of the film after use is very difficult and complicated. With the extension of the years of film mulching cultivation, the film is easy to gather inside the soil during recycling, thereby causing soil and environmental pollution. Therefore, a recycling device is needed when recycling the film.

[0003] In addition, the existing recycling device has the following disadvantages: when the recycling device is used, the flexibility of the ground film is reduced due to the long-term exposure to wind and sun, so the ground film is broken when the subsequent recycling device recycles the ground film, and the broken ground film is easily affected by the external wind, and the broken ground film floats in the air or other places, thereby polluting the air environment;

[0004] Moreover, when the soil is covered with mulch for a long time, the moisture and viscosity of the soil increase. Therefore, when the mulch is subsequently recycled, the soil stuck on the mulch cannot be removed in time, which easily leads to the weight and volume of the mulch, making it more difficult for the recycling equipment to handle it. In view of this, we propose a high-strength and easily recyclable mulch and a preparation method thereof. Summary of the invention

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] One of the purposes of the present invention is to provide a high-strength and easily recyclable ground film and a preparation method thereof, which comprises the following steps:

[0037] Step 1: The staff hangs the housing 1 to the traction device and ensures that the crushing structure 2 can operate normally. The crushing structure 2 rotates to crush the ground film, and at the same time drives the reciprocating structure 3 and the filtering and blowing structure 4 to separate and collect the collected ground film and soil, thereby completing the ground film recovery;

[0038] Step 2: The recycled mulch film is passed through a mulch film making device to dissolve, extrude and cool the mulch film to complete the mulch film preparation.

[0039] The second purpose of the present invention is that the recycled mulch is used for agricultural mulch and laid on the soil. If the mulch is not recycled, the waste mulch will remain in the soil. Since the plastic mulch is difficult to degrade naturally, it will cause the soil structure to be destroyed. Over a long period of time, the air permeability and water permeability of the soil will be reduced, affecting the growth of crops. For this reason, we provide a high-strength and easily recyclable mulch, please refer to Figure 1-Figure 10 , wherein a traction buckle 11 is fixedly connected to the surface of the shell 1, a collecting box 12 is detachably installed on the side of the shell 1, a crushing structure 2 for crushing the ground film is arranged inside the shell 1, and a reciprocating structure 3 for separating the ground film and the soil is arranged on the side of the crushing structure 2, and the reciprocating structure 3 is arranged inside the shell 1;

[0040] The ground film is broken by rotating the crushing structure 2, and at the same time, the reciprocating structure 3 and the filtering and blowing structure 4 are driven to shake up and down to separate the ground film and the soil. At the same time, the crushing structure 2 rotates and the filtering and blowing structure 4 shakes upward to move in opposite directions, so that the ground film and soil stuck to the crushing structure 2 are removed, and the filtering and blowing structure 4 is filled with gas to blow the separated ground film to the collection box 12.

[0041] The present invention takes into account that the recycling of existing used ground film is done manually by staff, and even manual recycling can easily cause damage to the ground film because the ground film is exposed to the natural environment for a long time and is affected by wind, sun and rain. Among them, ultraviolet rays can cause the polymer molecular chains in the ground film to break, causing the ground film to age and become brittle, and the mechanical strength to decrease. It is easy to break during the recycling process, and the broken ground film is easy to float in the air or other locations, polluting the surrounding environment. Therefore, the ground film is shoveled up through the front end of the shell 1, and the ground film is broken and tied up by rotating the crushing structure 2, so that the ground film is only broken in the inner cavity of the shell 1. Even if the ground film is not broken in time, it is only stored inside the shell 1, waiting for the crushing structure 2 to break and tie up the stored ground film, thereby reducing the intensity of manual work and preventing the ground film from floating to other locations to pollute the environment.

[0042] At the same time, when breaking and piercing the ground film, it is easy to tie up the soil and the ground film together, because when the soil is moist, the cohesive force is strong. Therefore, when the soil is humid, it is easy to adhere to the ground film. When the ground film is tied up, it will be lifted up together with the soil stuck to the ground film. Therefore, when the soil and the ground film are tied up by the crushing knife in the crushing structure 2, the filtering and blowing structure 4 can scrape off the soil and ground film tied up by the crushing knife in the crushing structure 2. At the same time, the reciprocating structure 3 reciprocates up and down to drive the filtering and blowing structure 4 to shake and separate the scraped soil and ground film, and when the filtering and blowing structure 4 shakes upward, it will resist the crushing knife in the rotating crushing structure 2, so that the filtering and blowing structure 4 blows out gas, quickly guides the separated ground film to the collection box 12 for collection, and quickly scrapes off the soil and ground film tied up by the crushing structure 2;

[0043] Furthermore, considering that the ground film is easily entangled on the rotating shaft of the crushing structure 2 when the crushing structure 2 works for a long time, if it is not cleaned in time, the ground film entangled on the rotating shaft will increase the rotational resistance of the rotating shaft, causing the rotation speed of the crushing structure 2 to decrease, thereby affecting the working efficiency of the entire equipment. In severe cases, the equipment may frequently jam or even stop running, and it is necessary to manually clean the entangled ground film frequently, thereby reducing the working efficiency of ground film recovery. Therefore, when the filtering and blowing structure 4 shakes up and down, the filtering and blowing structure 4 cleans the ground film entangled on the rotating shaft of the crushing structure 2, and when the filtering and blowing structure 4 shakes upward, it will counteract the crushing knife in the rotating crushing structure 2, so that the crushing knife in the crushing structure 2 can quickly scrape off the soil and ground film that are tied up, which can not only automatically clean the ground film entangled on the rotating shaft of the crushing structure 2, but also improve the working efficiency of removing the ground film.

[0044] First, it is convenient to drive the whole device to be driven by the traction device (tractor) to crush and recycle the ground film. For further disclosure of the structure of the crushing structure 2, please refer to Figure 1-Figure 4 The crushing structure 2 at least includes a motor 21, which is fixedly connected to the outer wall of the shell 1, and a film collecting wheel 22 is fixedly connected to the output end of the motor 21. The end of the film collecting wheel 22 away from the motor 21 is fixedly connected to a first rotating disk 23, and is hung on the traction device (tractor) through a traction buckle 11. Then the motor 21 is started to make the film collecting wheel 22 fixed at the output end of the motor 21 rotate, and then the traction buckle 11 and the shell 1 are pulled by the traction device (tractor) to move as a whole, so that the bottom of the inner cavity at the bottom of the shell 1 fits against the ground film, and the ground film is shoveled into the inner cavity of the shell 1. At the same time, when the film collecting wheel 22 rotates, the crushing knife therein will tie up the ground film in the inner cavity of the shell 1. Considering that the shell 1 will shovel up some soil when shoveling the ground film, when the film collecting wheel 22 ties up the ground film, the soil that is not adhered to the ground film will fall to the outside of the shell 1 from the leakage opening at the bottom of the shell 1. In addition, the ground film is tied up to facilitate subsequent collection.

[0045] The improved detailed structure of the present invention is as follows:

[0046] In order to facilitate the removal of the ground film tied up by the crushing knife in the film collecting wheel 22, the following specific structure needs to be disclosed in detail, please refer to Figure 6-Figure 8The reciprocating structure 3 at least includes a second rotating disk 31, which is rotatably connected to the outer wall of the shell 1. The second rotating disk 31 is transmission-connected to the first rotating disk 23 through a belt. A rotating column 32 is fixedly connected to the side of the second rotating disk 31 close to the shell 1. A guide plate 33 is abutted against the outer ring surface of the rotating column 32. The upper and lower sides of the guide plate 33 are fixedly connected to a limiting plate 34. The limiting plate 34 is slidably connected to the inside of the shell 1. When the film collecting wheel 22 rotates, the first rotating disk 23 is driven to rotate. The rotation of the first rotating disk 23 can drive the second rotating disk 31 to rotate through the belt transmission, and the rotation of the second rotating disk 31 can drive the rotating column 32 to rotate around the center of the second rotating disk 31. Since the guide plate 33 and the second rotating disk 31 are not connected, when the rotating column 32 rotates one hundred and eighty degrees around the center of the second rotating disk 31, the rotating column 32 will slide the maximum distance inside the guide plate 33, and during the sliding process, the guide plate 33 will be driven to move upward under the limit of the limit plate 34 and the outer shell 1. Then, when the rotating column 32 continues to be driven by the second rotating disk 31 to rotate three hundred and sixty degrees, the rotating column 32 will continue to slide the maximum distance inside the guide plate 33 (the initial position of the rotating column 32), and the sliding process will drive the guide plate 33 to move downward under the limit of the limit plate 34 and the outer shell 1, so as to facilitate the subsequent separation of the ground film and soil scraped off by the crushing structure 2 by the filtering and blowing structure 4.

[0047] At the same time, in order to remove the ground film tied up by the crushing knife of the film collecting wheel 22 and separate the ground film from the soil, the structure of the filtering and blowing structure 4 is further disclosed, please refer to Figure 7-Figure 9 The filter blowing structure 4 at least includes a filter plate 41, the filter plate 41 is fixedly connected to one side of the limit plate 34, the sliding plate 42 is slidably connected inside the slot opened in the filter plate 41, and a guide tube 43 is fixedly connected to the surface of the filter plate 41, and a plurality of air outlet holes 44 are opened on the surface of the guide tube 43, and a plurality of filter ports are also opened on the surface of the filter plate 41. When the limit plate 34 moves upward, it can drive the filter plate 41 to move upward. At this time, when the filter plate 41 moves upward on the side close to the film collecting wheel 22, it can contact the crushing knife in the rotation of the film collecting wheel 22, so that the ground film stuck by the crushing knife can be scraped off, and the scraped ground film will fall to the surface of the filter plate 41 for acceptance;

[0048] Next, when the limit plate 34 moves downward, it will drive the filter plate 41 to move downward, so that the limit plate 34 and the filter plate 41 can reciprocate up and down, and the ground film and soil carried by the filter plate 41 can be shaken up and down, so that the soil falls from the multiple filter ports opened in the filter plate 41 to the bottom of the outer shell 1, and falls from the leakage port opened in the outer shell 1 to the outside of the outer shell 1. In addition, since the filter plate 41 is inclined, the ground film separated by the filter plate 41 will be guided from the inclined and shaking filter plate 41 to the collection box 12 for storage, which is conducive to improving the subsequent processing of the collected ground film by subsequent staff, and the collection of the ground film is carried out inside the outer shell 1, which can prevent the external wind from blowing the ground film to other locations.

[0049] Furthermore, considering that the rotation speed of the film collecting wheel 22 is relatively fast, the film may be entangled on the rotating shaft of the film collecting wheel 22 when it is rolled up, and considering that the film filtered out by the filter plate 41 may stick to the surface of the filter plate 41, it is because when the soil is covered with the film for a long time, the moisture and viscosity of the soil are enhanced. Therefore, some soil will stick to the film when it is rolled up. Even if the soil is filtered out, the film is still sticky, making it easy for the film to stick to the filter plate 41. The following specific structural movement states need to be disclosed in detail, please refer to Figure 4-Figure 10 When the limit plate 34 at the top of the guide plate 33 is retracted on the inner wall of the shell 1, the filter plate 41 fixedly connected to the side of the limit plate 34 is in an upward state; when the limit plate 34 at the bottom of the guide plate 33 is retracted on the inner wall of the shell 1, the filter plate 41 fixedly connected to the side of the limit plate 34 is in a downward state;

[0050] When the filter plate 41 is in an upward state, the crushing blades in the film collecting wheel 22 are in contact with the surface of the sliding plate 42, and when the filter plate 41 is in a downward state, the crushing blades in the film collecting wheel 22 are in a state away from the surface of the sliding plate 42. When the filter plate 41 scrapes the ground film stuck by the film collecting wheel 22 upward, the filter plate 41 can also contact the rotating shaft of the film collecting wheel 22, so that the ground film wrapped around the rotating shaft of the film collecting wheel 22 is removed, and the crushing blades of the film collecting wheel 22 and the filter plate 41 are in relative motion, so that the filter plate 41 can quickly remove the ground film stuck on the crushing blades of the film collecting wheel 22 when scraping it. This is because, when the filter plate 41 and the crushing blades move relative to each other, there is a close contact between the two, and the edge of the filter plate 41 will directly contact the ground film on the crushing blades. This scraping action is just like using a scraper to remove dirt on the surface of an object, which is direct and effective, thereby improving the effect of removing the ground film;

[0051] Furthermore, when the crushing blade of the film collecting wheel 22 and the filter plate 41 move relative to each other, the crushing blade of the film collecting wheel 22 will squeeze the sliding plate 42 that is slidably connected inside the filter plate 41, so that the sliding plate 42 slides inside the filter plate 41 and generates gas. This is because the sliding plate 42 and the filter plate 41 are like a piston structure, and the piston structure is that when the gas pressure in the sealed space increases to a certain extent and forms a sufficient pressure difference with the external environment, the gas will be discharged from a specific channel, thereby realizing the output of the gas. Therefore, when the sliding plate 42 slides in the closed space inside the filter plate 41, the gas pressure in the filter plate 41 will increase to a certain extent, causing the gas to be discharged into the guide tube 43 and ejected from the air outlet 44, so that the filter plate 41 can receive the filtered ground film and blow it quickly, thereby reducing the ground film sticking to the filter plate 41, and can also improve the rapid diversion of the filtered ground film to the inside of the collection box 12.

[0052] Working principle: the staff hangs the traction buckle 11 on the traction device (tractor), and then starts the output end of the motor 21 to rotate, so that the film collecting wheel 22 rotates synchronously, and then the traction buckle 11 and the shell 1 are pulled by the traction device (tractor) to move as a whole, so that the ground film is scooped up at the bottom of the shell 1, and then the scooped ground film will pass through the crushing knife in the film collecting wheel 22 to rotate, and the ground film in the inner cavity of the shell 1 will be tied up, and then the film collecting wheel 22 will drive the first rotating disk 23 to rotate when the first rotating disk 23 rotates, and the rotation of the first rotating disk 23 can drive the second rotating disk 31 to rotate through the belt transmission, and the rotation of the second rotating disk 31 can drive the rotating column 32 to rotate around the center of the second rotating disk 31, so that the rotating column 32 drives the guide plate 33 to reciprocate up and down between the limit plate 34 and the shell 1, which is convenient for the subsequent driving of the filter blowing structure 4;

[0053] At the same time, when the limit plate 34 moves upward, it can drive the filter plate 41 to move upward. At this time, when the filter plate 41 moves upward near the side of the film collecting wheel 22, it can contact the crushing knife in the rotation of the film collecting wheel 22, so that the ground film held up by the crushing knife is scraped off, and the scraped ground film will fall to the surface of the filter plate 41 for acceptance. Then, when the limit plate 34 moves downward, it will drive the filter plate 41 to move downward, thereby the limit plate 34 and the filter plate 41 reciprocate up and down, and the ground film and soil accepted by the filter plate 41 are shaken up and down, so that the separated soil falls to the outside of the shell 1, and the ground film separated by the filter plate 41 will be diverted to the collection box 12 for storage;

[0054] Furthermore, when the filter plate 41 scrapes upwards the ground film stuck by the film collecting wheel 22, the filter plate 41 can also contact the rotating shaft of the film collecting wheel 22, so that the ground film wrapped around the rotating shaft of the film collecting wheel 22 can be removed, and the crushing knife of the film collecting wheel 22 is in relative motion with the filter plate 41, so that the filter plate 41 can quickly remove the ground film stuck on the crushing knife of the film collecting wheel 22 when scraping it, and, when the crushing knife of the film collecting wheel 22 and the filter plate 41 move relative to each other, the crushing knife of the film collecting wheel 22 will squeeze the sliding plate 42, so that the sliding plate 42 slides inside the filter plate 41 and generates gas, which is discharged into the inside of the guide tube 43 and ejected from the air outlet 44, which will cause the filter plate 41 to quickly blow the filtered ground film, thereby reducing the ground film sticking to the filter plate 41.
