Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a preliminary separation and lifting device for film and soil in a residual film recycling machine. Background Technology

[0002] Mulching technology effectively improves soil moisture content and crop water use efficiency, thereby increasing crop yield. Therefore, it is widely used in planting areas. However, because mulch film is generally thin, it gradually weathers and tears after crop harvest. The remaining film residue in the soil can not only entangle machinery during the following year's planting, affecting its efficiency, but also hinder seed germination, reducing crop yield. To avoid the negative impacts of residual film, it is necessary to actively collect it after harvest. Currently, residual film recycling machines are commonly used to collect film fragments remaining in the soil.

[0003] The operation of a residual film recycling machine generally consists of four steps: 1. Soil extraction: The soil extraction mechanism digs up large clumps of soil mixed with residual film and root stubble and pushes them onto the lifting mechanism; 2. Lifting: The lifting mechanism raises the mixture to a certain height so that it can be fed into a higher screening mechanism; 3. Screening: The screening mechanism screens the mixture (sieving off soil and leaving residual film, root stubble, and other impurities); 4. Collection: The remaining impurities in the screening mechanism are collected and recycled. However, in the lifting step, because the soil being transported is both clump-like and granular, the conventional conveying platform currently used is unable to efficiently transport it from low to high. Furthermore, the vibration of the machine causes the soil mixture to continuously slide towards the front (lower end) of the conveying platform, leading to lifting failures. A large amount of soil accumulates at the front of the conveying platform and is forced to the sides, easily causing blockages. Therefore, the lifting mechanism currently used in residual film recycling machines significantly restricts their working efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a preliminary separation and lifting device for membrane soil in a residual membrane recycling machine, so as to overcome the defects and deficiencies of existing related technologies and products as described in the background art.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a preliminary separation and lifting device for film and soil in a residual film recycling machine, including a main lifting device, an auxiliary clamping lifting device, and a reversing gear. The main lifting device includes a bearing, a drive shaft I, a front support wheel assembly, a rubber gear assembly, a rubber belt, and several grid bars. The drive shaft I is supported by a bearing fixedly installed on the frame of the residual film recycling machine. The rubber gear assembly is installed on the drive shaft I, and a sprocket I is installed at one end of the drive shaft I. The front support wheel assembly is fixedly installed on the frame of the residual film recycling machine, and the installation height of the front support wheel assembly is much lower than the installation height of the bearing. The grid bars are horizontally and spacedly fixedly installed on the rubber belt. The front end is supported by a front support wheel assembly, and the rear end of the rubber belt is supported by the rubber gear assembly via a grid bar. The rubber gear assembly meshes with the grid bar mounted on the rubber belt. The structure of the auxiliary clamping elevator is the same as that of the main elevator. Its lifting length is 1 / 2 to 2 / 3 of the lifting length of the main elevator. It is positioned above the main elevator, parallel to the main elevator, and forms a certain distance from it. A gear is installed at the other end of the drive shaft I of the main elevator. The reversing gear is fixedly installed through the frame of the residual film recycling machine. The reversing gear has a synchronous sprocket coaxial with it. The reversing gear meshes with the gear, and its synchronous sprocket is chain-driven with the sprocket II installed at one end of the drive shaft II of the auxiliary clamping elevator.

[0006] Furthermore, a pair of guide plates are provided at the rear end of the main elevator.

[0007] Furthermore, a torque limiter is provided between the drive shaft I of the main elevator and the sprocket I.

[0008] The beneficial effects of this utility model are: the preliminary separation and lifting device for residual film and soil in the residual film recycling machine can effectively ensure that the mixture of residual film, soil and stubble can be quickly and stably lifted obliquely, and during the lifting process, it can also play a certain role in squeezing and crushing the mixture, resulting in the preliminary separation of residual film and soil (most of the crushed soil will automatically fall back to the ground from the gap between the grid bars of the main elevator under the action of gravity), which is conducive to the further screening of the mixture by the subsequent screening mechanism, thereby greatly improving the working efficiency of the residual film recycling machine.

[0012] A preliminary separation and lifting device for membrane soil in a residual film recycling machine, such as Figure 1 , Figure 2 As shown, it includes a main elevator 1, an auxiliary clamping elevator 2, and a reversing gear 3. The main elevator 1 includes a bearing, a drive shaft I1-1, a front support wheel assembly 1-3, a rubber gear assembly 1-4, a rubber belt 1-5, and several grid bars 1-6. The drive shaft I1-1 is supported by a bearing fixedly mounted on the frame of the residual film recycling machine. The rubber gear assembly 1-4 is mounted on the drive shaft I1-1, and a sprocket I1-2 is mounted at one end of the drive shaft I1-1. The front support wheel assembly 1-3 is fixedly mounted on the frame of the residual film recycling machine, and the installation height of the front support wheel assembly 1-3 is much lower than the installation height of the bearing. The grid bars 1-6 are horizontally spaced and fixedly mounted on the rubber belt 1-5. The front end of the rubber belt 1-5 is supported by the front support wheel assembly 1-3, and the rear end of the rubber belt 1-5... The grid bar 1-6 is supported by the rubber gear set 1-4, and the rubber gear set 1-4 meshes with the grid bar 1-6 installed on the rubber belt 1-5. The structure of the auxiliary clamping elevator 2 is the same as that of the main elevator 1. Its lifting length is 1 / 2 to 2 / 3 of the lifting length of the main elevator 1. It is set above the main elevator 1, parallel to the main elevator 1 and forming a certain distance. A gear 1-7 is installed at the other end of the drive shaft I1-1 of the main elevator 1. The reversing gear 3 is fixedly installed through the frame of the residual film recycling machine. At the same time, the reversing gear 3 has a synchronous sprocket 3-1 coaxial with it. The reversing gear 3 meshes with the gear 1-7. Its synchronous sprocket 3-1 is chain driven by the sprocket II2-2 installed at one end of the drive shaft II2-1 of the auxiliary clamping elevator 2.

[0013] When the residual film recycling machine is working, the mixture of residual film, soil, and stubble scraped out by the shovel or rotary blade mechanism is pushed onto the grid bars 1-6 of the main elevator 1. Some of the broken soil can leak out from the gaps between the grid bars 1-6. When the mixture is lifted between the main elevator 1 and the auxiliary clamping elevator 2, the auxiliary clamping elevator 2 works with the main elevator 1 to form a certain clamping force on the mixture, preventing the mixture from sliding down due to the height increase and mechanical vibration, and ensuring that the mixture can be quickly and stably conveyed upwards at an angle. At the same time, the clamping force formed by the auxiliary clamping elevator 2 and the main elevator 1 on the mixture can play a certain squeezing and crushing role on the mixture, which is beneficial to the subsequent screening mechanism for further screening of the mixture.

[0014] A pair of guide plates 4 are provided at the rear end of the main elevator 1 of the elevator mechanism to improve the guiding of the mixture and prevent the mixture from slipping off both sides of the rear end of the main elevator 1.

[0015] To prevent damage to the transmission mechanism due to accidental jamming caused by foreign objects or malfunctions, a torque limiter 1-8 is installed between the drive shaft I1-1 and the sprocket I1-2 of the main elevator 1. The torque limiter 1-8 is a commercially available product, also called a torque overload protector. The sprocket I1-2 drives the torque limiter 1-8, which in turn drives the drive shaft I1-1 (similar to a clutch) through its elastic friction plates, thus protecting the transmission mechanism.

[0016] The above embodiments are only used to explain the present utility model and are not intended to limit the protection of the present utility model. Any non-substantial modifications made based on the essential solution of the present utility model shall fall within the protection scope of the present utility model.
