Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to scraper-type warehouse conveying equipment. Background Technology

[0002] Scraper conveyors are a type of mechanical equipment widely used for material handling. They primarily use the movement of scrapers to transport materials from one location to another. Their structure typically includes a conveying trough, scraper chain, and drive unit. Due to their high efficiency, stability, and adaptability, scraper conveyors are widely used in agriculture, particularly in the conveying and processing of materials such as grains, feed, and fertilizers.

[0003] Existing technologies typically employ screw conveyors for transporting small particles or powdery materials such as grains. However, due to the limited distance of screw conveyors and the gap between the screw blades and the casing, material residue is easily caused, resulting in poor performance. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of limited conveying distance and material residue in the existing technology, and to propose a scraper-type outbound conveying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A scraper-type outbound conveying device includes a conveying box and a hopper located in the middle of the conveying box near one end of the conveying box. The conveying box is equipped with a conveying assembly, which includes two sprockets rotating at both ends of the conveying box. The two sprockets are connected by a chain drive. A plurality of first scrapers and a plurality of second scrapers are fixedly spaced on the surface of the chain, and the plurality of first scrapers and the plurality of second scrapers are staggered on the surface of the chain.

[0007] In some embodiments, the two ends of the second scraper abut against the two sides of the inner wall of the conveying box, and the length of the first scraper is shorter than the length of the second scraper.

[0008] In some embodiments, the first scraper is made of nylon and the second scraper is made of polyurethane.

[0009] In some embodiments, a baffle is fixed inside the hopper. The baffle is rhomboid in shape and open at both ends, and the chain, the first scraper and the second scraper located above pass through the inside of the baffle.

[0010] In some embodiments, the conveying box includes multiple boxes with openings at both ends, and the multiple boxes are fixedly connected by bolts.

[0011] In some embodiments, a baffle is fixed inside the hopper. The baffle is rhomboid in shape and open at both ends. The baffle is used to allow material to enter the conveying box from both sides of the first scraper and the second scraper. The chain, the first scraper and the second scraper located above pass through the inside of the baffle for protection of the first scraper and the second scraper.

[0012] In some embodiments, the lower surface of the conveying box is provided with a plurality of discharge ports spaced apart, and the plurality of discharge ports are respectively closed by a plurality of gate valves.

[0013] In some embodiments, a vibratory unloader is fixed to the side of the hopper.

[0014] Compared with the prior art, the present invention provides a scraper-type outbound conveying device, which has the following beneficial effects.

[0015] 1. This utility model, by setting up a conveying component, enables the first scraper to push a large amount of material for conveying, while the two ends of the second scraper abut against the conveying box and are made of polyurethane material. Polyurethane material is relatively soft and can better fit the inner wall of the conveying box. Therefore, the area scraped by the first scraper can be scraped again to avoid residue in the conveying box.

[0016] 2. This utility model, by setting a baffle inside the hopper, avoids a large amount of material from adhering to the chain surface when the material falls to the bottom of the hopper, thus affecting the use of the chain. By setting a support plate, it is convenient to support the first scraper and the second scraper located above, thereby improving the stability of their movement process.

[0017] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-5 The scraper-type discharge conveyor includes a conveyor box 2 and a hopper 1 located in the middle of the conveyor box 2 near one end of the conveyor box 2. The conveyor box 2 is connected to the hopper 1. A vibrating unloader 7 is fixed on the side of the hopper 1. The vibrating unloader 7 is an existing structure and will not be described in detail. The conveyor box 2 is equipped with a conveying assembly 3. The conveyor box 2 includes multiple boxes with openings at both ends. The multiple boxes are fixedly connected by bolts.

[0027] The conveying assembly 3 includes two sprockets 301 rotating at both ends of the conveying box 2. The two sprockets 301 are connected by a chain 302. Multiple first scrapers 303 and multiple second scrapers 304 are fixedly fixed at intervals on the surface of the chain 302. The multiple first scrapers 303 and multiple second scrapers 304 are staggered on the surface of the chain 302. The two ends of the second scrapers 304 abut against the inner walls of the conveying box 2. The length of the first scraper 303 is shorter than the length of the second scraper 304. The first scraper 303 is made of nylon, and the second scraper 304 is made of polyurethane. Metal plates are fixed to both sides of the first scraper 303 and the second scraper 304. The first scraper 303 and the second scraper 304 are fixed to the surface of the chain 302 by the metal plates. The sprocket 301 near the hopper 1 is driven to rotate by a drive motor, which is fixed to the surface of the conveying box 2.

[0028] Understandably, the material gradually falls into hopper 1 and gathers at the bottom. By installing a vibrating unloader 7, hopper 1 vibrates, allowing the material to slide smoothly downwards while preventing it from sticking to the inner wall. A drive motor rotates the sprocket 301, which, in conjunction with the chain 302, moves multiple first scrapers 303 and second scrapers 304. These scrapers push the material towards the end of the conveyor box 2 away from hopper 1. As the material gradually falls to the bottom of hopper 1, the first scrapers 303 and second scrapers 304 continuously convey it, keeping the height of the material gathered at the bottom of hopper 1 below that of the conveyor box 2. The height of the first scraper 303 and the second scraper 304 at the bottom is such that the first scraper 303 is shorter than the second scraper 304 and is made of nylon, which is relatively hard and can push a large amount of material to move. The two ends of the second scraper 304 are in contact with the conveyor box 2 and are made of polyurethane, which is relatively soft. When the first scraper 303 and the second scraper 304 are at the bottom of the conveyor box 2, they can contact the bottom of the conveyor box 2 under the action of gravity and fit better with the inner wall of the conveyor box 2. Therefore, the area scraped by the first scraper 303 can be scraped again to avoid residue in the conveyor box 2. By setting the conveyor box 2 as multiple boxes, it is convenient to transport materials and the length of the conveyor box 2 can be flexibly adjusted when materials need to be transported over different distances.

[0029] For details, please refer to Figure 3 The hopper 1 has a baffle 101 fixed inside. The baffle 101 is rhomboid and open at both ends. The chain 302, the first scraper 303 and the second scraper 304 located above pass through the baffle 101. The bottom of the hopper 1 is provided with an inclined surface that causes the material to gather towards the position of the first scraper 303 and the second scraper 304.

[0030] It is understandable that by setting a baffle 101 inside the hopper 1 and allowing the upper chain 302, the first scraper 303, and the second scraper 304 to pass through the baffle 101, the chain 302 is protected, preventing a large amount of material from adhering to the surface of the chain 302 when the material falls to the bottom of the hopper 1, thus affecting the use of the chain 302. The material enters the bottom of the hopper 1 from both sides of the baffle 101. At the same time, the baffle 101 occupies the internal space of the hopper 1, which can reduce the falling speed of the material and prevent the material from falling too fast and completely burying the first scraper 303 and the second scraper 304, thus affecting their normal operation.

[0031] Specifically, there are two support plates 4 fixed inside the conveyor box 2. The two support plates 4 are located on both sides of the chain 302 and are parallel to the chain 302. The two support plates 4 are fixed to the inner wall of the conveyor box 2 by multiple fixing rods 401. Both ends of the two support plates 4 are arc-shaped and downward. The support plates 4 support the first scraper 303 and the second scraper 304 located above.

[0032] It is understandable that by setting the support plate 4, it is easier to support the first scraper 303 and the second scraper 304 located above, thereby improving the stability of their movement process and preventing the chain 302 from sagging due to its toughness, which would affect the stability of the conveying component 3.

[0033] Specifically, the lower surface of the conveyor box 2 is provided with multiple discharge ports 5 spaced apart, and the multiple discharge ports 5 are closed by multiple slide gate valves 6 respectively.

[0034] It is understandable that by opening multiple discharge ports 5 at intervals on the lower surface of the conveyor box 2, it is convenient to discharge materials at multiple points.

[0035] In this invention, during use, the hopper 1 is connected to the vertical silo storing powdered materials. The vibrating unloader 7 ensures that the materials fall smoothly into the hopper 1. The drive motor drives the sprocket 301 to rotate. With the cooperation of the sprocket 301 and the chain 302, multiple first scrapers 303 and second scrapers 304 are moved, causing the first scrapers 303 and second scrapers 304 to push the materials towards the end of the conveying box 2 away from the hopper 1. The first scrapers 303 push a large amount of material to move, while the second scrapers 304 are responsible for scraping the area scraped by the first scrapers 303 again to avoid residue in the conveying box 2. Under the action of the support plate 4, the first scrapers 303 and second scrapers 304 located above are supported to improve the stability of their movement process and prevent the chain 302 from sagging due to its toughness, which would affect the stability of the conveying assembly 3.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
