Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to an anti-spill conveying device for a hammer type crusher. Background Art

[0002] Hammer mill is an industrial crushing equipment, which is often used to crush raw materials (such as stone, ore, wood, plastic, waste, etc.) into smaller particles or powder. Its working principle is to hit and crush the raw materials with high-speed rotating hammers or hammers, and then separate the crushed materials through screens or other devices. This kind of crusher is often used in construction, mining, metallurgy, chemical industry, pharmaceutical, waste treatment and other industries, and has a wide range of uses.

[0003] At present, when conveying materials, hammer mills mostly use transmission mechanisms such as transmission belts. When using transmission belts for conveying, one end of the transmission belt is placed on the discharge port of the mill so that the falling materials fall directly onto the transmission belt. However, in actual use, there is a certain distance between the transmission belt and the discharge port. When the materials fall, the reaction force generated will cause the materials to splash to the outside of the transmission belt. At the same time, when conveying some materials, some impurities will adhere to the outer wall of the transmission belt. The presence of impurities will increase the friction resistance of the transmission belt, thereby reducing the transmission efficiency and increasing the energy loss. Therefore, it is necessary to redesign an anti-spill conveying device for hammer mills to address the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a spill-proof conveying device for a hammer type crusher.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, the connecting mechanism comprises a screw sleeve threadedly connected to the threaded section of the reciprocating screw, and the scraper is fixedly connected to the upper end surface of the screw sleeve.

[0008] Preferably, a limit rod is fixedly connected to the inner wall of the frame, and the limit rod is slidably connected to the lead screw sleeve.

[0009] Preferably, the outer wall of the frame is rotatably connected with a synchronous wheel 1 and a synchronous wheel 2, and the synchronous wheel 1 and the synchronous wheel 2 are coaxially fixedly connected to the transmission roller and the reciprocating screw respectively.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model provides a buffer plate, a spring, a slider and other devices. When the material at the crusher falls to the upper end of the buffer plate, the impact force generated drives the buffer plate to slide downward. At the same time, the slider compresses the spring downward. The spring can buffer the impact force from the material, thereby avoiding the spillage of the material, helping to keep the working environment clean, reducing the frequency of cleaning work, and improving the comfort of the working environment.

While ensuring the cleaning effect, the cost of replacing the scraper is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Reference Figure 2 The connecting mechanism includes a screw sleeve 9 threadedly connected to the threaded section of the reciprocating screw 7, and a scraper 10 is fixedly connected to the upper end surface of the screw sleeve 9. The reciprocating screw 7 drives the scraper 10 to slide on the outer wall of the transmission belt 2, so as to scrape off impurities attached to the outer wall of the transmission belt 2, thereby preventing the impurities from affecting the transmission efficiency of the transmission belt 2.

[0022] Reference Figure 2 The inner wall of the frame 1 is fixedly connected with a limit rod 8, and the limit rod 8 is slidably connected with the screw sleeve 9. The limit rod 8 can limit the sliding direction of the scraper 10 to ensure that its sliding direction is always along the specified direction.

In the utility model, the specific function of the device is: when using the device, align the buffer plate 6 on the device with the discharge port of the crusher. When the material is discharged, it falls to the upper end surface of the buffer plate 6 in advance. The impact force generated at this time drives the slider 13 to slide downward, and at the same time compresses the set spring 12. The set spring 12 can absorb the impact force generated, and then under the gravity of the material itself, it falls to the upper end surface of the transmission belt 2, and is transported to the designated position through the transmission belt 2, thereby achieving the purpose of preventing material splashing;
