Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and is an all-in-one machine for returning straw to fields, recycling residual film and round baling. Background Art

[0002] Nowadays, film mulching cultivation technology has been widely used in various places, especially in arid areas. With its remarkable characteristics of increasing temperature, retaining moisture, inhibiting weed growth, promoting early maturity of crops and increasing yields, it has indeed brought benefits to farmers. However, if the old plastic film used in farming is not recycled in time and effectively, it will cause soil compaction and degradation, hinder crop germination, cause rapid decline in land quality and reduced utilization efficiency, and bring serious white pollution to the environment, becoming a major environmental hazard.

[0003] At present, many post-autumn residual film recycling machines have been developed at home and abroad, mainly including nail-tooth type, tooth chain type, rake-tooth type residual film recycling machines, etc. The operation process mainly includes film removal, film picking, film rolling and film unloading. Among them, film removal is the first step in the residual film recovery process, and the effect of film removal affects the residual film recovery rate. For the nail-tooth residual film recycling machine, the film removal device, as the film removal component of the whole machine, is affected by the aging of the ground film and the influence of impurities such as crop straw that easily cause the film removal device to be congested during operation, making the film removal effect of the film removal device not obvious, and the impurities congested at the film removal device are difficult to discharge. After working for a period of time, the film removal device needs to be manually cleaned. At the same time, there is a lot of soil, sand and stones attached to the collected residual film, which is easy to damage the spring teeth and increase the failure rate.

[0004] In addition, due to the existence of ridges, gullies and earth mounds on the land, the land is uneven. When walking on uneven land, the soil recovery mechanism of the residual film recovery device always maintains the same soil burial depth, which easily leaves residual film behind and reduces the recovery rate of residual film. In the process of residual film removal, in order to make the film removing device adapt to the ground conditions and ensure the operating depth without missing residual film, when the machine body is longer and wider, that is, the entire frame is larger, for example, when the ground surface is undulating front and back and there are slopes left and right, the film removing device cannot float up and down with the undulations of the ground, which will cause the working parts to not partially enter the ground or the burial depth to be insufficient and miss the residual film, resulting in a low film removing rate. Summary of the invention

[0005] The utility model provides an all-in-one machine for returning straw to fields and recovering residual film into round balers, which overcomes the deficiencies of the above-mentioned prior art and can effectively solve the problems of the existing residual film recovery machines, such as the difficulty in discharging impurities clogged in the film removing device and the low film removing rate.

The straw crushing component is used to crush the straw stubble and throw it into the first conveying auger 2. The first conveying auger 2 transports the crushed straw stubble to both sides of the frame 1. The film lifting assembly can fluctuate up and down with the height of the ground and lift the residual film in the stratum and then transport it to the residual film baling assembly. The baling assembly is used to wind the residual film into a cylindrical shape. A driving assembly is installed on the upper front side of the frame 1. The driving assembly is respectively installed with the straw crushing component, the first conveying auger 2, the film lifting assembly and the residual film baling assembly for transmission.

The connecting cylinder is fixedly installed together with the upper part of the mounting frame 4. A central axis 5 is rotatably installed on the inner side of the lower part of the mounting frame 4. A film removal roller is fixedly installed on the outer side of the central axis 5. A plurality of film removal components are evenly distributed along the circumference of the outer side of the film removal roller. Each film removal component includes a plurality of film removal knives fixedly installed on the outer side of the film removal roller at left and right intervals. The left and right parts of the mounting frame 4 are detachably fixedly installed with a left guide rail 6 and a right guide rail 7 of the same structure, corresponding to the position between two adjacent film removal components. A floating plate is hingedly installed on the outer side of the film removal drum, and a surface of the floating plate away from the central axis 5 is provided with film removal holes corresponding to the film removal knives. Annular guide grooves 8 are provided on the right side of the left guide rail 6 and the left side of the right guide rail 7. A separation point 9 and a film removal point 10 are provided in the guide groove 8. Each guide groove is provided with a guide wheel 11 rotatably installed with the corresponding position of the floating plate. When the guide wheel 11 moves from the film removal point 10 to the separation point 9 along the guide groove 8 with the central axis 5, the end of the film removal knife gradually retracts into the corresponding film removal hole. When the guide wheel 11 moves from the separation point 9 to the film removal point 10 along the guide groove 8 with the central axis 5, the end of the film removal knife gradually extends from the corresponding film removal hole.

[0043] According to the requirements, the guide wheel 11 can be a known technology, such as a rolling bearing. When in use, the front part of the frame 1 is hingedly mounted on the tractor, so that the lower end of the mounting frame 4 can float up and down with the advancement of the traction equipment, and the residual film in the soil can be collected in a centralized manner according to the height of the ground. The drive assembly and the drive shaft 47 of the tractor are installed together through the known technology, such as through a universal shaft and a reduction box.

[0044] When the residual film recovery operation is performed, the tractor pulls the frame 1 forward, and the output shaft of the tractor drives the central shaft 5 to rotate. The central shaft 5 rotates in a counterclockwise direction, and the blade of the lowest film-removing knife is inserted into the soil to pick up the residual film in the soil layer. As the guide wheel 11 rotates along the guide groove 8 from the film-removing point 10 to the separation point 9, the blade of the film-removing knife gradually retracts into the corresponding film-removing hole. When the roller moves to the separation point 9, the film-removing knife is completely retracted into the film-removing hole. At this time, the inner wall of the demolding hole can scrape off the residual film attached to the film-removing knife. The scraped residual film slides to the rear along the floating plate, and the residual film enters the residual film baling assembly and is wound into a cylindrical shape, so that the residual film can be collected in a centralized manner. The guide wheel 11 continues to move along the guide groove 8 along the central shaft 5 When moving from the separation point 9 to the film removal point 10, the end of the film removal knife gradually extends out of the corresponding film removal hole. When the guide wheel 11 moves to the film removal point 10, the blade of the film removal knife completely extends out of the film removal hole. At this time, the blade of the film removal knife is inserted into the residual film in the soil. In this way, the central axis 5 continues to rotate, and the film removal assembly and the floating plate can continuously pick up the residual film in the soil and separate it. The left and right parts of the frame 1 are detachably fixed with left guide rails 6 and right guide rails 7 of the same structure, which is convenient for adjusting the left guide rails 6 and right guide rails 7, so that the positions of the separation point 9 and the film removal point 10 can be adjusted, so that the lower part of the frame 1 can still realize the recovery of residual film during the up and down floating process, which can avoid the phenomenon that the residual film is blocked on the film removal knife and is difficult to be discharged during the film removal operation, thereby improving the film removal rate.

This makes the force on the central axis 5 and the film-taking drum more uniform during the residual film recovery operation, and can prevent the first cutter disc 12 and the second cutter disc 13 from deformation. Through such a setting, it is also convenient to maintain and replace the blades, which can reduce the failure rate and maintenance difficulty.
