Description

Technical Field

[0001] The utility model belongs to the technical field of grain and oil machinery and relates to a horizontal scraper conveyor. Background Art

[0002] A scraper conveyor is a mechanical device used to transport materials, primarily for short distances, horizontally or at an angle of no more than 15 degrees. It is widely used in grain and oil processing. However, since the scraper chain and other mechanisms within the scraper conveyor must be in full contact with the material during operation, materials and debris can easily adhere to the scraper chain. If this is not cleaned, after changing the conveyed material, different materials may become mixed, affecting the quality of the subsequent grain and oil products. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned problems existing in the existing technology and to provide a horizontal scraper conveyor, which aims to clean the scraper chain inside it after completing the transportation of grain and oil, thereby avoiding the mixing and contamination between different materials.

[0004] The object of the utility model can be achieved through the following technical solutions: a horizontal scraper conveyor, comprising a loading head, a middle trough, a sprocket, a plate chain and a tail; characterized in that the lower end of the tail is provided with a discharge port, and the lower part of the tail is provided with a swing frame; the middle part of the swing frame is hinged on the outer wall of the tail, and the two ends of the swing frame are respectively provided with a handle and a brush roller; the brush roller is located at the lower part of the tail, the brush roller is rotatably connected to the swing frame, and two opposite outer walls of the tail are provided with a strip-shaped through hole for the brush roller rotating shaft to pass through the machine and swing; a first hanging ear is provided on both sides of the swing frame, and each first hanging ear is located between the handle and the hinge axis of the swing frame; a second hanging ear is provided on the two opposite outer walls of the tail, and a tension spring is provided between the first hanging ear and the second hanging ear on the same side of the tail for connection, and when the first hanging ear, the second hanging ear and the hinge axis of the swing frame on the same side of the tail are in the same straight line, each tension spring is in a stretched to the longest state.

[0005] Preferably, a plurality of tensioning bolts are arranged between the two side walls of the middle groove, and each tensioning bolt is covered with a plastic sleeve. Each plastic sleeve can rotate freely in the middle groove, and each plastic sleeve can support the plate chain that moves to the upper part of the middle groove.

[0006] The utility model has the advantages:

[0007] 1. In this conveyor, a brush roller is provided in the tail of the conveyor. The brush roller can be kept away from the plate chain during normal conveying. When the plate chain needs to be cleaned, the brush roller can be kept close to the plate chain, making it more flexible and convenient to use, and can effectively avoid mutual contamination between materials.

[0008] 2. In this conveyor, the plastic sleeves supported under the upper plate chain can rotate freely, which greatly reduces the running resistance of the plate chain, thereby reducing the operating energy consumption and wear of this conveyor. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0014] like Figure 1 、 Figure 2 and Figure 3 As shown, a horizontal scraper conveyor includes a head 1, a middle trough 2, a sprocket 3, a plate chain 4 and a tail 5; a discharge port 51 is provided at the lower end of the tail 5, and a swing frame 6 is provided at the lower part of the tail 5; the middle part of the swing frame 6 is hinged on the outer wall of the tail 5, and a handle 61 and a brush roller 62 are provided at both ends of the swing frame 6; the brush roller 62 is located at the lower part of the tail 5, and the brush roller 62 is rotatably connected to the swing frame 6, and two opposite outer side walls of the tail 5 are provided with a shaft for the brush roller 62 to pass through the swing frame 6. The strip-shaped through hole 52; a first hanging ear 63 is provided on both sides of the swing frame 6, and each first hanging ear 63 is located between the handle 61 and the hinge axis of the swing frame 6; a second hanging ear 53 is provided on the two opposite outer walls of the tail 5, and a tension spring 7 is provided between the first hanging ear 63 and the second hanging ear 53 on the same side of the tail 5 to connect them, and when the first hanging ear 63, the second hanging ear 53 and the hinge axis of the swing frame 6 on the same side of the tail 5 are in the same straight line, each tension spring 7 is in a stretched to the longest state.

[0015] When the horizontal scraper conveyor is feeding, we can lift the handle 61 to make the swing frame 6 swing around the hinge axis, drive the brush roller 62 downward, and then keep it away from the plate chain 4. Because when the first hanging ear 63, the second hanging ear 53 and the hinge axis of the swing frame 6 are in the same straight line, the tension spring 7 is stretched to its longest state. Therefore, when the handle 61 is lifted and passes this point, the brush roller 62 is kept away from the plate chain 4 under the action of the continuous contraction force of the tension spring 7, without affecting the normal conveying operation of the conveyor. When the conveying of one material is completed and the conveying material needs to be changed, we can keep the inner plate chain 4 running and pull down the handle 61 to drive the brush roller 62 upward until the brush roller 62 is in close contact with the plate chain 4, and then clean the continuously running plate chain 4, remove the materials and debris adhering to the plate chain 4, and avoid the mutual mixing and contamination of different materials. And because the outer peripheral surface of the plate chain 4 is uneven (the scraper is higher than the chain link), the plate chain 4 will cause the brush roller 62 and the entire swing frame 6 to swing back and forth continuously during continuous operation, thereby achieving the effect of constantly "knocking" on the tail 5, and the debris and dust adhering to the inner wall of the tail 5 can be shaken off in time, making the self-cleaning effect of this conveyor better.

[0016] like Figure 1 As shown, a number of tension bolts 21 are arranged between the two side walls of the middle trough 2. Each tension bolt 21 is sheathed with a plastic sleeve 22. Each plastic sleeve 22 can rotate freely within the middle trough 2 and supports the plate chain 4 that travels to the upper portion of the middle trough 2. The plastic sleeves 22 supported below the upper plate chain 4 can rotate freely, significantly reducing the operating resistance of the plate chain 4, thereby reducing the operating energy consumption and wear of the conveyor.

[0017] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
