Description

Technical Field

[0001] This utility model relates to the field of screening roller technology, specifically a roller structure for separating straw from plastic film. Background Technology

[0002] Mulching is widely used to increase soil temperature, retain moisture, and suppress weed growth, thereby promoting crop growth. However, during use, mulch film is prone to leaving residues in farmland due to natural aging or mechanical damage. After harvesting crops, straw is usually returned directly to the field or left on the soil surface as mulch, while the mulch film may not be cleaned up in time, causing the two to mix together. Due to inadequate mulch film recycling technology or operations, some mulch film fragments remain in the soil and are collected or disposed of along with the straw.

[0003] Common straw and plastic film separating drums mainly separate plastic film fragments by rotating a cylindrical screening structure. However, the drum rotates as a whole, and the feeding hopper and discharge port rotate synchronously with the drum. This makes it impossible to feed and discharge materials during the screening process, so screening can only be done in batches, resulting in discontinuous operation and reduced screening efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a roller structure for separating straw from plastic film, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a device frame and a drum body. The drum body is installed inside the device frame. The drum body is composed of a screening section, a front sleeve, and an end sleeve arranged side-by-side, and is inclined towards the front end. The screening section is rotatably connected between the front sleeve and the end sleeve. A support plate is fixed inside the device frame, and the front sleeve and the end sleeve are fixed to the support plate. A drive shaft is rotatably connected inside the device frame, and the end of the drive shaft is inserted into the drum body. A connecting rod is fixed between the drive shaft and the inner side of the screening section. A drive motor and controller for driving the drive shaft are fixed on the outer side of the device frame. A blowing assembly is provided inside the front sleeve.

[0006] Preferably, a connecting sleeve is installed between the screening section and the front sleeve and the end sleeve, the two ends of the screening section are fixed inside the connecting sleeve, and the ends of the front sleeve and the end sleeve are rotatably connected inside the connecting sleeve.

[0007] Preferably, the blower assembly includes an air pump and a nozzle, an upper end plate is fixed to the upper inner side of the front end sleeve, the air pump is fixed to the outer side of the upper end plate, the nozzle is fixed to the inner side of the upper end plate, and a connecting pipe is fixed between the air pump and the nozzle.

[0008] Preferably, the nozzle's air outlet opening faces obliquely downwards.

[0009] Preferably, a bottom baffle is fixed below the inner side of the end sleeve, the drive shaft passes through the bottom baffle, and the bottom baffle is rotatably connected.

[0010] Preferably, a feeding hopper is fixed at the upper end of the equipment frame, the bottom of the feeding hopper is inserted into the drum body, and a guide frame is fixed below the front end of the drum body.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the main body of the drum is divided into three sections, and the independent rotation of the screening section is used to separate and screen the mulch film and straw. During the screening process, the normal feeding and unloading are not affected, and the purpose of continuous screening can be achieved. In addition, a blowing structure is set at the outlet, which can blow the mulch film fragments that have been missed back into the screening section for better and more thorough separation.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1This utility model provides a technical solution: it includes a frame 1 and a drum body 2. The drum body 2 is installed inside the frame 1. A feeding hopper 4 is fixed at the upper end of the frame 1. The bottom of the feeding hopper 4 is inserted into the drum body 2. A guide frame 25 is fixed below the front end of the drum body 2. The drum body 2 is composed of a screening section 21, a front sleeve 22, and an end sleeve 23 arranged side by side, and the whole body is inclined towards the front end. The screening section 21 is rotatably connected between the front sleeve 22 and the end sleeve 23. A connecting sleeve 26 is installed between the screening section 21 and the front sleeve 22 and the end sleeve 23. The screening section 21 is fixed at both ends in the connecting sleeve 26. The front sleeve 22 and the end sleeve 23 are rotatably connected in the connecting sleeve 26. A support plate 5 is fixed in the equipment frame 1. The front sleeve 22 and the end sleeve 23 are fixed on the support plate 5. A drive shaft 3 is rotatably connected in the equipment frame 1, and the end of the drive shaft 3 is inserted into the drum body 2. A connecting rod 31 is fixed between the drive shaft 3 and the inner side of the screening section 21. A drive motor 32 and a controller 11 that drive the drive shaft 3 to rotate are fixed on the outer side of the equipment frame 1. A blowing assembly is provided in the front sleeve 22.

[0016] The blower assembly includes an air pump 61 and a nozzle 63. An upper end plate 6 is fixed to the upper inner side of the front end sleeve 22. The air pump 61 is fixed to the outer side of the upper end plate 6, and the nozzle 63 is fixed to the inner side of the upper end plate 6. A connecting pipe 62 is fixed between the air pump 61 and the nozzle 63. The air outlet of the nozzle 63 faces downwards. A bottom baffle 24 is fixed to the lower inner side of the end sleeve 23. The drive shaft 3 passes through the bottom baffle 24, and the bottom baffle 24 is rotatably connected.

[0017] Working principle: First, connect the entire device to an external power source. Then, the output of the drive motor 32 drives the drive shaft 3 to rotate. The transmission of the connecting rod 31 drives the screening section 21 to rotate. At this time, the feeding hopper 4 can be used to feed straw, which passes through the end sleeve 23 and enters the screening section 21 for screening. The bottom baffle 24 can prevent the straw material entering the end sleeve 23 from falling. The rotation of the screening section 21 can screen and drop the broken plastic film into the equipment frame 1, and the straw will slide out from the front sleeve 22, achieving the purpose of continuous feeding and screening, improving screening efficiency. During the sliding process, the air pump 61 can be used to drive air to continuously spray from the nozzle 63. Under a certain airflow, the lighter plastic film can be prevented from sliding out and blown back into the screening section 21 for re-screening, reducing the risk of missed screening and ensuring that straw and plastic film fragments can be better separated.
