[0001] The utility model relates to a buried scraper conveyor, in particular to a head-up buried scraper conveyor, and belongs to the technical field of conveying equipment. Background Art

[0002] As an important part of the food industry, the edible vegetable oil industry focuses on the research and development, production and sales of various edible oil and fat products, aiming to meet the diverse cooking and eating needs of consumers. The industry has a rich variety of products, including soybean oil, peanut oil, corn oil, rapeseed oil, olive oil and other categories, each with its own flavor and nutritional value.

[0003] Vegetable oil processing uses oil-rich plant seeds as raw material. After cleaning, crushing, softening, and tempering, crude oil is extracted through physical pressing or chemical extraction. After impurities and harmful substances are removed through refining equipment, edible oil is obtained. The TMSS horizontal buried scraper conveyor plays a vital role in transporting oil between various work sections and equipment. Processing workshops are increasingly demanding on equipment, and workshop designs are shifting from extensive designs to more sophisticated and compact designs.

[0004] The existing buried scraper conveyors have the following problems: The TMSS type horizontal buried scraper conveyor can only carry out linear transportation, resulting in some work sections having no opportunities when the space is compressed; and the volume of the TMCF type lifting scraper conveyor is significantly larger than the TMSS type horizontal buried scraper conveyor. The structure of the TMCF type lifting scraper conveyor is also relatively complex, and the equipment cost is also high. Utility Model Content

[0005] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and utility model title of this application, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0006] In view of the above problems and / or the problems existing in the prior art, the present utility model is proposed.

[0007] The purpose of the utility model is to overcome the problems existing in the prior art and provide an overhead buried scraper conveyor. A curved section is set in the middle of the horizontal scraper conveyor to lift the head part upward, making the workshop layout more flexible, and can effectively compress the space occupied by the conveying equipment, avoiding space waste caused by poor layout of the conveyor.

[0008] In order to solve the above technical problems, the utility model provides an overhead buried scraper conveyor, comprising a head and a tail, wherein the head and the tail are connected by a conveying housing, the middle section of the conveying chain passes through the conveying housing and the two ends respectively pass around the head sprocket and the tail sprocket, and a plurality of scrapers are evenly fixed along the length direction of the conveying chain, the conveying housing comprises a horizontal section housing, a curved section housing and a lifting section housing connected in sequence by flanges, the rear end of the horizontal section housing is connected to the tail housing, and the front end of the lifting section housing is connected to the head housing;

[0009] The top of the curved section shell is an arc-shaped top cover, the bottom of the curved section shell is an arc-shaped bottom plate, and both sides of the curved section shell are fan-shaped side plates; an arc-shaped partition is provided between the arc-shaped top cover and the arc-shaped bottom plate;

[0010] A pair of downward-extending clamping plates are symmetrically welded below the middle of the arc-shaped partition plate, and a downward-extending pressure chain vertical plate is clamped and fixed between the two clamping plates. Downward-extending polymer wear-resistant plates are symmetrically fixed on both sides of the lower end of the pressure chain vertical plate. The lower edge of the pressure chain vertical plate and the polymer wear-resistant plate are both arc-shaped, and the curvature matches the arc-shaped bottom plate. The bottom of the two polymer wear-resistant plates rests against the lower conveying chain so that the lower scraper fits on the arc-shaped bottom plate.

[0011] As an improvement of the present invention, ribs are respectively connected to the lower sides of the two sides of the arc-shaped partition, and a plurality of through holes are provided along the length direction of the ribs. The outer ends of the through holes are respectively welded with sleeves passing through them, and the outer ends of the sleeves are flush with the edges of the arc-shaped partition. The pull rods pass through the sleeves on both sides to fix the arc-shaped partition between the two fan-shaped side plates.

[0012] As a further improvement of the present invention, the upper ends of the two clamping plates are bent outward to form an eight-shaped opening.

[0013] As a further improvement of the present invention, a row of waist-shaped holes extending vertically are provided on the lower edge of the pressure chain vertical plate, and bolts pass through the waist-shaped holes to fix the two polymer wear-resistant plates on both sides of the pressure chain vertical plate.

[0014] As a further improvement of the present invention, an inspection door is provided in the middle of the arc-shaped top cover.

[0015] As a further improvement of the present invention, a mirror frame is fixed to the middle of the fan-shaped side panel of the curved section shell, and a mirror glass is fixed to the inner side of the mirror frame by countersunk screws, and the inner wall of the mirror glass is flush with the inner wall of the fan-shaped side panel.

[0016] As a further improvement of the present invention, return wear-resistant baffles are fixedly connected to both sides of the inner wall of the arc-shaped top cover.

[0017] Compared with the existing technology, the utility model has achieved the following beneficial effects: 1. A curved section is set in the middle of the TMSS type horizontal scraper conveyor to lift the head part upward. In the case of non-straight line, it avoids the use of two conveyors for transportation, making the workshop layout more flexible, effectively compressing the space, and avoiding the waste of space caused by the difficult arrangement of conveyors;

[0018] 2. The curved section of the scraper is equipped with a chain pressing device, which can effectively prevent the chain from hanging in the curved section when the chain is tightened, resulting in a decrease in conveying efficiency;

[0019] 3. The polymer wear-resistant plate of the pressure chain is installed vertically. Compared with the horizontal installation, the vertically installed polymer wear-resistant plate can adopt waist-shaped holes, which can realize the adjustment of the polymer wear-resistant plate up and down, making the wearable thickness of the polymer wear-resistant plate thicker and avoiding frequent replacement of the polymer wear-resistant plate. The horizontally installed polymer wear-resistant plate needs to be installed with countersunk screws. After the polymer wear-resistant plate is worn, the screw head is easily exposed, which is easy to cause wear of the conveyor chain. The polymer wear-resistant plate of the present invention is fixed from the side with bolts, and the situation of screws wearing the conveyor chain will not occur.

[0020] 4. The horizontal installation of polymer wear-resistant plates requires two vertical plates side by side, occupying a large slot space, which not only affects conveying efficiency but also increases conveying resistance. This solution uses two polymer wear-resistant plates installed vertically on both sides of the middle fixed plate. The middle fixed pressure chain vertical plate is a single vertical plate, which has a good stress state, saves slot space, effectively ensures conveying efficiency, and reduces conveying resistance.

[0033] In the following description of the present invention, the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not mean that the device must have a specific direction.

[0034] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific figures. Obviously, the embodiments described are only a part of the present invention, not all of the embodiments.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] like Figures 1 to 6As shown, the overhead buried scraper conveyor of the present invention includes a head 1 and a tail 5, which are connected by a conveying shell. The middle section of the conveying chain 6 passes through the conveying shell and the two ends respectively pass around the head sprocket and the tail sprocket. A plurality of scrapers 7 are evenly fixed along the length direction of the conveying chain 6. The conveying shell includes a horizontal section shell 4, a curved section shell 3 and a lifting section shell 2 connected in sequence by flanges. The rear end of the horizontal section shell 4 is connected to the tail shell, and the front end of the lifting section shell 2 is connected to the head shell. A horizontal section feed port 4a is provided along the conveying direction of the horizontal section shell 4, a lifting section feed port 2a is provided at the top of the lifting section shell 2, and a head discharge port 1a is provided below the head 1.

[0037] The top of the curved section shell 3 is an arc-shaped top cover 3a, the bottom of the curved section shell 3 is an arc-shaped bottom plate 3c, and the two sides of the curved section shell 3 are fan-shaped side panels 3b. An inspection door 3h is provided in the middle of the arc-shaped top cover 3a, and the return wear-resistant baffle 3a1 is fixedly connected to the two sides of the inner wall of the arc-shaped top cover 3a, and the upper edge of the return scraper rests under the return wear-resistant baffle 3a1.

[0038] An arc-shaped partition 3d is provided between the arc-shaped top cover 3a and the arc-shaped bottom plate 3c. Ribs 3d1 are respectively connected to the lower sides of the arc-shaped partition 3d. A plurality of through holes are provided along the length direction of the ribs 3d1. The outer ends of the through holes are respectively welded with sleeves 3d2 passing through them. The outer ends of the sleeves 3d2 are flush with the edges of the arc-shaped partition 3d and abut against the inner walls of the fan-shaped side plates 3b. The pull rods 3m respectively pass through the sleeves 3d2 on both sides to fix the arc-shaped partition 3d between the two fan-shaped side plates 3b.

[0039] A pair of downward-extending clamping plates 3e are symmetrically welded to the lower middle portion of the curved partition 3d. The upper ends of the two clamping plates 3e are bent outward to form an "e"-shaped opening. A downward-extending chain pressure plate 3f is clamped and fixed between the two clamping plates 3e. Downward-extending polymer wear-resistant plates 3g are symmetrically fixed to the lower ends of the chain pressure plate 3f. The lower edges of the chain pressure plate 3f and the polymer wear-resistant plates 3g are both curved, and their curvature matches that of the curved bottom plate 3c. The bottoms of the two polymer wear-resistant plates 3g abut against the lower conveyor chain 6, allowing the lower scraper 7 to adhere to the curved bottom plate 3c.

[0040] A row of waist-shaped holes 3f1 extending vertically is provided on the lower edge of the pressure chain vertical plate 3f. Bolts pass through the waist-shaped holes 3f1 to fix the two polymer wear-resistant plates 3g on both sides of the pressure chain vertical plate 3f.

[0041] A mirror frame 3j is fixed to the middle of the fan-shaped side plate 3b of the curved section housing 3. A mirror glass 3k is fixed to the inner side of the mirror frame 3j by countersunk screws. The inner wall of the mirror glass 3k is flush with the inner wall of the fan-shaped side plate 3b.

[0042] Material enters the overhead scraper conveyor through the horizontal section inlet 4a and the elevated section inlet 2a. Driven by the conveyor chain 6, the material moves toward the conveyor head, ultimately dropping to the conveyor head outlet 1a and entering the next process. During the conveying process, the conveyor chain 6 exerts a thrust on the material along the direction of its motion. This also creates internal friction within the material (commonly known as material pushing). This internal friction is greater than the combined force of the friction between the material and the housing and the component of the material's gravity along the housing, allowing the material to move forward along with the conveyor chain 6.

[0043] Compared to traditional horizontal buried scraper conveyors, the overhead buried scraper conveyor incorporates a curved section housing 3. This causes the tight edge of the chain that propels the material forward to become stretched and suspended in the curved section, causing the scraper's lower edge to separate from the curved base plate 3c. This can lead to material residue and reduced conveying efficiency. The chain-pressing uprights 3f and the polymer wear-resistant plate 3g at their lower ends act as chain-pressing elements in the curved section, forcing the conveyor chain 6 and scraper to advance along the curved base plate 3c. This ensures that the scraper's lower edge always adheres to the curved base plate 3c, ensuring efficient conveying.

[0044] When the material reaches the curved section during the forward advancement, it will be blocked by the pressure chain vertical plate 3f and the polymer wear-resistant plate 3g. The pressure chain vertical plate 3f is installed vertically with a single plate, which occupies very limited space in the machine slot, reducing the obstruction of the material. At the same time, the upper end of the pressure chain vertical plate 3f is clamped between the plywood 3e and locked with a row of bolts. The two plywood 3e are in an inverted eight shape and the upper ends are welded to the partition. The installation of the two pressure chain devices can effectively disperse the stress on the root of the pressure chain vertical plate 3f during the operation of the equipment, avoiding stress concentration.

[0045] Two polymer wear-resistant plates 3g are clamped on both sides of the lower part of the pressure chain vertical plate 3f. The polymer wear-resistant plates 3g are installed vertically. The holes for installing the polymer wear-resistant plates 3g on the pressure chain vertical plate 3f are waist-shaped holes 3f1. The height of the polymer wear-resistant plates 3g can be adjusted, that is, the clamping force of the pressure chain can be adjusted. It can also be adjusted downward after the bottom of the polymer wear-resistant plate 3g is worn, thereby increasing the service life of the polymer wear-resistant plate 3g; at the same time, the polymer wear-resistant plate 3g is fixed to the lower end of the pressure chain vertical plate 3f with bolts from the side. Even if the polymer wear-resistant plate 3g is subjected to greater wear, it will not scratch the chain and will not cause wear of the chain.

[0046] The side panels of the curved section are each equipped with a sight glass, which can be used to observe the stability of the compression chain device and the wear of the polymer wear-resistant plate 3g during the operation of the equipment, and can also be used as an inspection window. The compression chain device can be maintained after removal. The inner side of the sight glass 3k of the sight glass is fixed to the sight glass frame 3j with countersunk screws, and the inner side of the sight glass 3k is flush with the inner wall of the side panel, so no material will accumulate at the sight glass. After long-term operation, the sight glass 3k remains clear, which is convenient for observing the internal situation of the equipment.
