Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of screening equipment, and in particular to a double-screen drum type fertilizer screening device. Background Technology
[0002] Organic fertilizer, mainly derived from plants and / or animals, provides comprehensive nutrition for crops and has a long-lasting effect. It increases and renews soil organic matter, promotes microbial reproduction, and improves the physical, chemical, and biological properties of the soil. It is a major nutrient for green food production. Organic fertilizer raw materials from plants and animals are screened and classified by an organic fertilizer screening machine before subsequent synthetic processing. Existing technology announcement CN210935949U discloses a fertilizer screening device, including a screening box and a hinged door. The top of the screening box has a feed inlet. A roller is located inside the screening box, and rotating shafts are located on both sides of the roller. The rotating shafts are rotatably connected to the inner wall of the screening box. One side of the rotating shaft extends out of the screening box, and a motor is located on one side of the screening box. The motor has a main pulley and a second main pulley in sequence. A driven pulley is located on the rotating shaft, and a belt connects the driven pulley and the second main pulley. However, the screening efficiency is not high, which affects the quality of fertilizer. At the same time, the material is prone to clogging the screening holes, resulting in reduced work efficiency. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a double-screen drum fertilizer screening device that can perform multi-stage screening, improve screening effect, prevent organic fertilizer from clogging, and improve work efficiency.
[0004] This utility model discloses a double-screen drum fertilizer screening device, comprising a screening drum, a screening component, a cleaning component, a scraping component, a support component, and a discharge component. The left and right ends of the bottom of the screening drum are mounted on the support component. The screening component is installed inside the screening drum, and the scraping component is also installed inside the screening component. The discharge component is installed at the bottom of the screening drum. Material is added to the screening component for multi-stage screening. At the same time, the cleaning component and the scraping component can clean the screening component, effectively preventing organic fertilizer blockage and improving work efficiency. The screened material is discharged through the discharge component.
[0005] Preferably, the screening component includes a screening inner cylinder, two supporting rotating rings, a disc, a drive motor, and a screening outer cylinder. The screening inner cylinder is located inside the screening drum. Supporting rotating rings are installed at both ends of the screening inner cylinder. Limiting rotating grooves are opened on the inner walls of both ends of the screening drum, and the supporting rotating rings are rotatably installed in the limiting rotating grooves. A disc is installed at the right end of the screening inner cylinder. The drive motor is installed above the right side wall of the screening drum, and the output end of the drive motor is connected to the disc. The screening outer cylinder is installed inside the screening drum and located outside the screening inner cylinder. When the material enters the screening inner cylinder, the drive motor is started, which drives the screening inner cylinder to rotate inside the screening drum through the disc, thereby turning the material and screening it. The screened material passes through the screening inner cylinder and enters the screening outer cylinder, where it is screened again. This multi-stage screening can be achieved, improving the screening effect.
[0006] Preferably, the cleaning component includes a crossbar, multiple connecting rods, and a cleaning plate. The crossbar is installed on the left side wall of the screening cylinder and is located in the middle of the inner screening cylinder. Multiple connecting rods are evenly installed at the bottom of the crossbar, and a cleaning plate is installed at the bottom of the connecting rods. The cleaning plate contacts the inner wall of the screening cylinder. When the screening cylinder drives the organic fertilizer to rotate, the organic fertilizer is stirred by the connecting rods to improve the screening effect. At the same time, the cleaning plate can clean the inside of the screening cylinder to avoid blockage and improve the screening quality.
[0007] Preferably, the scraping component includes multiple sets of support rods and multiple cleaning scrapers. The multiple sets of support rods are axially installed on the outer wall of the screening inner cylinder, and the cleaning scrapers are installed on the outer wall of the support rods. The cleaning scrapers are in contact with the inner wall of the screening outer cylinder. When the screening inner cylinder rotates, the cleaning scrapers are driven to rotate by the support rods, which scrapes and cleans the inside of the screening outer cylinder, avoiding clogging by organic fertilizer, accelerating the screening effect, and improving practicality.
[0008] Preferably, the support component includes two legs, two base plates, and a cross plate. The two legs are installed at the left and right ends of the bottom of the screening cylinder, the base plates are installed at the bottom of the legs, and the cross plate is installed between the two base plates. The legs and base plates support the bottom of the screening cylinder to ensure stability during use, while the cross plate increases the connection strength.
[0009] Preferably, the discharge component includes a first discharge pipe, a second discharge pipe, a guide plate, a bracket, a second guide plate, a third discharge pipe, multiple support rods, and a receiving plate. The first discharge pipe is installed on the right side wall of the screening cylinder, and its input end communicates with the inside of the inner screening cylinder. Multiple discharge holes are provided on the disc. The second discharge pipe is installed on the lower part of the left side wall of the screening cylinder and communicates with the inside of the outer screening cylinder. The guide plate is installed on the right side wall of the screening cylinder, located below the first discharge pipe. The bracket is installed on the outer wall of the bottom of the right support leg. The second guide plate is installed on the bracket and located at the second discharge pipe. Below the feed pipe, the third discharge pipe is installed in the middle of the bottom of the screening cylinder. Multiple support rods are installed on the top of the horizontal plate, and a receiving plate is installed on the top of the support rods. The receiving plate is located below the third discharge pipe. The material screened out in the inner screening cylinder passes through the discharge hole and enters the first discharge pipe. The material is received and discharged by the discharge plate. At the same time, the material screened out in the outer screening cylinder is discharged through the second discharge pipe and is received by the second discharge plate. The material that falls into the screening cylinder is discharged through the third discharge pipe and is received and discharged by the receiving plate. This allows for the separate discharge of screened materials, making it convenient to use.
[0010] Preferably, it also includes a feed pipe, a feed hopper, and two discharge rings. The feed pipe is installed on the left side wall of the screening cylinder, and the output end of the feed pipe is connected to the inside of the screening cylinder. The feed hopper is installed at the input end of the feed pipe, and discharge rings are symmetrically installed on the left and right sides inside the screening cylinder. The feed pipe and feed hopper facilitate the addition of materials into the screening cylinder. After the material is screened and falls into the screening cylinder, the discharge rings on both sides guide the material towards the center, thereby accelerating the material discharge efficiency.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the material is added into the screening component and screened in multiple stages. At the same time, the cleaning component and the scraping component can clean the screening component, effectively preventing the organic fertilizer from clogging and improving work efficiency. The screened material is discharged through the discharge component. Attached Figure Description
