Description

Technical Field

[0001] This utility model belongs to the technical field of cement raw material unloading equipment, and in particular relates to a cement raw material unloading device. Background Technology

[0002] Cement raw materials are the fundamental substances in cement production, mainly including four categories: calcareous raw materials, silica-alumina raw materials, ferrous corrective raw materials, and fuels. Among them, calcareous raw materials are mainly limestone, which provides calcium oxide in cement clinker; silica-alumina raw materials, such as clay, shale, and sandstone, supplement silica and alumina; ferrous corrective raw materials adjust the iron oxide content in clinker and optimize its calcination performance; and fuels are mainly pulverized coal, which provides heat for kiln calcination and also participates in some chemical reactions.

[0003] When cement raw materials are unloaded, they fall rapidly from the rear of the truck. During the scattering process, the initial dust volume is very large. This initial dust is further dispersed by airflow, resulting in a relatively high initial dust rate in conventional cement raw material handling.

[0004] Therefore, we propose a cement raw material unloading device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of high initial dust generation rate in conventional cement raw material processing, and to propose a cement raw material unloading device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cement raw material unloading device includes a truck cargo box. A guide frame is fixedly connected to the side of the cargo box, and a constraint sleeve is slidably installed on the lower part of the guide frame. Spring buckles are slidably installed inside the guide frame and constraint sleeve. A tubular nylon sleeve is fixedly connected to the rear of the cargo box, and an elastic band is fixedly connected to the lower part of the tubular nylon sleeve. A buckle is fixedly connected to the lower end of the elastic band, and the buckle engages with the spring buckle. The spring buckle also engages with the cargo box. During unloading, the tubular nylon sleeve guides the cement raw material to slide down along it, and also blocks the unloading point, preventing upward-splashing dust and reducing the dust generation rate during unloading.

[0008] Preferably, the truck cargo box includes a box body, and the side of the box body has a fastening groove.

[0009] Preferably, the guide frame includes a guide sleeve, the lower end of which is fixedly connected to a guide rod, and the guide sleeve is fixedly connected to the housing.

[0010] Preferably, a fixing block is fixedly connected to the lower end of the guide rod, and the fixing block is fixedly connected to the housing.

[0011] Preferably, the constraint sleeve includes a sleeve body that is slidably mounted on the guide rod. The sleeve body has a first spring piece inside, the upper end of which is fixedly connected to the sleeve body. The elastic force of the first spring piece acts on the snap fastener, pressing it against the housing, thus maintaining the constraint sleeve and snap fastener at the same height, facilitating the placement of the buckle on the snap fastener.

[0012] Preferably, the spring clip includes a second spring piece, the lower part of which is fixedly connected to a clip block, which fastens into a clip groove. The second spring piece is slidably installed inside the sleeve and guide sleeve. The upper end of the second spring piece is fixedly connected to a stop block, and the lower part of the second spring piece is fixedly connected to a clip post. The clip ring and the clip post are fitted together. When the clip ring is fitted onto the clip post, the clip post is pulled down, which acts downward on the second spring piece. The clip post is then released, allowing the clip block to fasten into the clip groove. The clip post constrains the clip ring, and the clip ring tightens the tubular nylon sleeve, which covers the box. When the box is loaded, this also reduces the dust rate of cement raw materials along the way.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. Utilize the elastic force of the first spring clip to press the spring clip onto the box body, so that the restraint sleeve and the spring clip maintain the same height, making it convenient to put the buckle on the spring clip.

[0015] 2. Place the buckle on the buckle post, pull the buckle post downwards, and the buckle post will act downwards on the second spring piece to release the buckle post, so that the buckle block is fastened in the buckle groove. The buckle post restrains the buckle post, and the buckle post tightens the tubular nylon sleeve. The tubular nylon sleeve covers the box. When the box is loaded, it can also reduce the dust rate of cement raw materials along the way. Attached Figure Description
