Description

A compound cleaning machine

technical field

The utility model relates to the field of grain processing, in particular to a compound cleaning machine.

Background technique

The existing compound cleaning machine includes: a blower, a specific gravity table, and an eccentric transmission mechanism. When working, the material enters the specific gravity table, and due to the difference in specific gravity and suspension speed, the heavier material sinks to the bottom of the specific gravity table due to the difference in specific gravity and suspension speed. Under the action of reciprocating motion, the grain suspended on the upper layer flows to the finished product outlet at the lower end of the specific gravity table under the action of its own weight and wind force, and the stones flow to the high end of the specific gravity table, thereby separating the grain and stones. Some manufacturers add a suction hood to the specific gravity table to prevent dust, and the winnowing effect is low, and the vibration source adopts a separate eccentric drive, which does not balance the force in the horizontal direction of the specific gravity table. The balance is poor, and it is easy to cause the whole machine Damage-type vibration increases the failure rate of equipment. After the material is dedusted by the suction hood, it still contains a large amount of crumbs and tiny particles. After falling into the specific gravity table, there will be three problems: the crumbs will block the fish scale holes or leak from the fish scale holes; some crumbs will be mixed with light impurities. Discharged from the light miscellaneous outlet, causing broken particles and impurities to mix together; some slightly larger broken particles will stay in the middle of the specific gravity table, which will eventually affect the specific gravity screening effect; and large and small impurities cannot be removed. Adding classification before entering the specific gravity machine will increase equipment and space.

Utility model content

The technical problem to be solved by the utility model is to provide a compound cleaning machine which has a good dust removal effect and can effectively remove large and small impurities mixed in the grain.

The technical scheme adopted by the utility model is: a compound cleaning machine, which includes a frame, a feeding hopper arranged on the frame, a wind separation device connected with the feed hopper, and a wind separation device connected with the discharge port. The screen box, the specific gravity screening device that is arranged on the lower side of the screen box and communicates with the discharge port of the screen box, and the crank that is used to drive the vibration of the screen box between the screen box and the specific gravity screening device; There is a lower discharge port and an upper stone discharge port on the top.

One end of the crank in the utility model is hinged with the screen box, and the other end is hinged with the stone-removing table of the specific gravity screening device; the middle position of the crank is hinged with the frame so that it can rotate around the hinge point.

The screen box of the utility model is provided with upper and lower layers of screen frames, and elastic balls are arranged in the screen frames.

The positive effects of the utility model are: 1. A screen box with two layers of screen frames is added between the winnowing device and the specific gravity screening device, which can effectively remove large and small impurities; there are elastic balls in the screen frame, which can effectively Clean the sieve to prevent the clogging of the sieve holes; it is more convenient to replace the sieve, and it is convenient for users to use. 2. Add wind separation device to avoid dust and be more environmentally friendly. 3. The screen box has a specific gravity table to drive the vibration, which is connected by a crank. The vibration direction of the screen box and the specific gravity table is opposite, which can effectively balance the vibration of the whole machine and improve the stability of the equipment operation. 4. Wind selection, grading and screening, and specific gravity destoning are completed at one time, reducing workers, equipment, and sites, and can effectively save energy and reduce consumption.
