Description

Technical Field

[0001] This utility model relates to the field of sludge feeding technology, specifically a dry sludge feeding mechanism. Background Technology

[0002] Sludge feeding on conveyor belts typically uses scrapers, which are usually mounted on rigid scraper frames and made of a single piece of steel plate. Existing scrapers generally have a fixed, one-piece design, making them unadjustable. Their rigid connection means that when encountering hard knots or filter cloth wrinkles, they will continue scraping along the original trajectory, unable to flexibly change position. The current one-piece design requires high precision in both the initial machining and assembly of the scraper blades; if this precision is compromised, certain points on the conveyor belt may not be scraped, resulting in incomplete sludge feeding. Furthermore, with this one-piece design, if the scraper blades are damaged or partially worn, the entire scraper needs to be replaced, leading to high costs. The rigid connection of existing scrapers, especially when encountering hard knots, can prevent flexible adjustment and may tear the conveyor belt, causing damage.

[0003] Therefore, we propose a dry mud feeding mechanism to solve the problems of some points not being scraped by the mesh belt, incomplete dry mud feeding, and high cost due to the need to replace the entire scraper when it is damaged. Utility Model Content

[0004] The purpose of this invention is to provide a dry mud feeding mechanism to solve the problem mentioned in the background art that the box cannot be enlarged and a larger box needs to be purchased for plant growth.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dry mud feeding mechanism, including a scraper main shaft, one end of which is fixedly connected to a scraper pressure adjusting gear, a spring fixing bracket is fixedly connected to the scraper main shaft, a bracket fixing sleeve is provided on one side of the spring fixing bracket and is rotatably mounted with the scraper main shaft, a scraper is fixedly provided below the bracket fixing sleeve, the scrapers on the scraper main shaft are arranged in staggered layers, and an extension scraper is slidably connected to the upper surface of the scraper.

[0006] Preferably, the spring fixing bracket includes one spring bracket or two spring brackets.

[0007] Preferably, a spring is provided between the upper surface of the scraper and the spring fixing bracket.

[0008] Preferably, the extended scraper is connected to the scraper via a scraper adjusting block.

[0009] Preferably, the bracket fixing sleeve can be fixed to the scraper spindle by a positioning pin.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the scrapers can be arranged in layers and staggered by the spring fixing bracket and the bracket fixing sleeve to realize the layered design of the scrapers. It does not adopt one-piece molding. If a single scraper is damaged, the individual scraper can be replaced. Furthermore, the pressure of the spring can be adjusted by the positioning pin on the bracket fixing sleeve to adjust the pressure between the scraper and the filter cloth to a suitable value. The extended scraper can be extended according to the actual filter cloth situation to make the pressure between each scraper and the filter cloth even and ensure the sludge scraping effect.

[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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0015] Please see Figure 1-2 This utility model provides an embodiment of a dry mud feeding mechanism, including a scraper main shaft 1, a scraper pressure adjusting gear 2 fixedly connected to one end of the scraper main shaft 1, a spring fixing bracket 3 fixedly connected to the scraper main shaft 1, a bracket fixing sleeve 4 provided on one side of the spring fixing bracket 3, the bracket fixing sleeve 4 being rotatably installed with the scraper main shaft 1, a scraper 5 fixedly provided below the bracket fixing sleeve 4, an extension scraper 6 slidably connected to the upper surface of the scraper 5, a spring 7 provided between the upper surface of the scraper 5 and the spring fixing bracket 3, the extension scraper 6 being connected to the scraper 5 through a scraper adjusting block 8, the position and tilt angle of the scraper 5 on the scraper main shaft 1 being adjusted by the bracket fixing sleeve 4, so that the spring 7 is subjected to different extrusion forces, thereby realizing the pressure adjustment of the filter cloth. During scraping, the extension length of the extension scraper 6 on the individual scraper 5 can be adjusted by the adjusting block 8 to scrape filter cloths of different thicknesses or shapes. The adjusting block 8 consists of a rotating bolt and a fixing block, one end of which is movably connected to the extension scraper 6, and the other end is threadedly connected to the fixing block, which is located on the scraper 5.

[0016] There are two types of spring fixing brackets 3: one is a spring fixing bracket 3 with only one spring bracket, and the other is a spring fixing bracket 3 with two spring brackets. The two types of brackets correspond to two positions. When the spring fixing bracket 3 is located on one side of the scraper 5 and does not need to be connected to the other scraper 5, it is a spring fixing bracket 3 with only one spring bracket. When the spring fixing bracket 3 is located between the two scrapers 5, it is a spring fixing bracket 3 with two spring brackets installed.

[0017] The scrapers 5 on the scraper main shaft 1 are arranged in a staggered manner to scrape the filter cloth as a whole. This method can be used for filter cloths of different widths. Furthermore, when a scraper 5 is damaged, the damaged scraper 5 can be disassembled individually for repair.

[0018] The outer side of the bracket fixing sleeve 4 is provided with a threaded positioning pin 9. When the bracket fixing sleeve 4 and the spring 7 are installed, the bracket fixing sleeve 4 is fixed on the scraper main shaft 1 by the positioning pin 9. The position and direction of the bracket fixing sleeve 4 are adjusted by the positioning pin, so as to facilitate the adjustment of the extrusion force of the spring 7.

[0019] Working principle: When in use, the scrapers 5 are first arranged in a staggered manner in space, with the scrapers overlapping in the direction of the main shaft 1, to ensure that all parts of the filter cloth can be scraped; the extended scraper 6 is installed on the scraper 5, and the extended scraper 6 can be adjusted by adjusting the adjusting block 8, and the extension of each extended scraper 6 can be adjusted individually to make the pressure between each scraper 5 and the filter cloth even, so as to ensure the sludge scraping effect.

[0020] The bracket fixing sleeve 4 is fixed axially by a positioning pin. The pin can rotate. The spring is adjusted by the positioning pin to adjust the pressure between the scraper 5 and the filter cloth to a suitable value. When encountering wrinkles or hard points in the filter cloth, the spring 7 is stretched to generate a buffer, allowing the scraper to pass over the wrinkles or hard points without damaging the filter cloth. The scraper pressure adjusting gear 2 is installed at one end of the scraper main shaft 1. The scraper main shaft 1 is connected to the external frame through a bearing seat and can rotate. When the scraper 5 is close to the filter cloth, the scraper pressure adjusting gear 2 is driven to rotate by an external rack that can move linearly according to the sludge scraping effect. The scraper pressure adjusting gear 2 is rotated until the sludge scraping effect is good, the pressure is adjusted appropriately, and the filter cloth is well protected. Then the external rack is fixed, and the scraper pressure adjusting gear 2 and the scraper main shaft 1 are fixed at the same time.
