Problems solved by technology

Because the wool row is sealed with such flexible wool fiber bundles, the impact strength against shot sand splashing is weak, and the sealing effect is not high, and because the hook lever arm frequently enters and exits the notch, the hair fiber bundles of the wool row are compressed and deformed after a long period of time. In the process of reset and extension, the sealing performance will inevitably be reduced

Embodiment Construction

[0015] See figure 1 with figure 2 As shown, the invention is described below by taking the application of the invention in the notch on the top of the cleaning chamber of the hook type shot blasting machine as an example:

[0016] A sealing device for the cleaning room of the hook type shot blasting machine, the hard blocking block 1 and the hard blocking block 2, the two hard blocking blocks can be made of wood, plastic or metal, with hard blocking One end of the block 1 is provided with a rotating shaft, and the hard plugging block 2 is provided with a rotating shaft on the same side end. The driving mechanism of the two hard plugging modules includes a connecting rod rotating mechanism and a return elastic body. There are two connecting rod slewing mechanisms, corresponding to the hard blocking block 1 and the hard blocking block 2. Each connecting rod slewing mechanism includes a linear push rod 3, a eccentric rotating mechanism, and the eccentric rotating mechanis...

Abstract

The invention discloses a sealing device for a cleaning chamber of a lifting hook type shot blasting machine. The sealing device is provided with two hard plugging blocks, the two hard plugging blocks can be in butt joint or be separated from each other, each hard plugging block is provided with a driving mechanism, rotary shafts are disposed at ends of the same sides of the two hard plugging blocks, each driving mechanism consists of two connecting rod rotating mechanisms and a return elastic body, and each connecting rod rotating mechanism comprises a direct-acting push rod and a rotating eccentric mechanism. The sealing device is high in impact resistance, good in sealing effect and long in service life.

Description

[0001] Technology Territory [0002] The invention relates to a sealing device used at the top of the cleaning chamber of a hook-type shot blasting machine at the notch position where the hook lever arm enters and exits, or the suitable position of other equipment. Background technique [0003] The shot blast machine uses a high-speed rotating impeller to throw projectiles onto the continuously overturned workpiece in the drum to achieve the purpose of cleaning the workpiece. It belongs to the scope of casting machinery. It is suitable for sand cleaning, rust removal, descaling and surface strengthening of castings and forgings under 15 kg in various industries. [0004] The hook type shot blasting machine is the standard model of the shot blasting machine. Its working cylinder diameter ranges from 900 to 1300 mm and the height ranges from 1300 to 2200 mm. The standard hook type shot blasting machine model has 2-7 shots. The maximum load-bearing capacity is up to 10,000 kg. It i...
