Description

Technical Field

[0001] The utility model belongs to the technical field of mushroom screening, and specifically relates to a pre-screening device on a mushroom screening machine. Background Art

[0002] Mushrooms are fleshy, tender, delicious in taste, unique in aroma, and rich in nutrition. They are a kind of food that combines food and medicine, and have high nutritional, medicinal, and health care values.

[0003] When processing mushrooms, it is necessary to screen them by size to improve their quality. When screening, a mushroom screening machine is required. Most of the existing mushroom screening machines are vibrating screens. The mushrooms are poured onto the vibrating screen, and then the vibrating screen is driven to shake by a vibration source to screen the mushrooms. However, there are still the following technical problems when using this screening equipment:

[0004] 1. Since the top of the vibrating screen is at a certain distance from the ground, when manually pouring mushrooms, the mushrooms need to be lifted to the top of the vibrating screen before pouring. Although the weight of the mushrooms is light, the box for loading mushrooms still has a certain weight. Moreover, as time goes by, the number of mushrooms transported increases, and the physical consumption of the workers also increases.

[0005] 2. When screening mushrooms, some mushrooms will get stuck in the mesh holes of the screen. At this time, manual cleaning is required, and the workers need to clean one hole by one hole, resulting in a large labor intensity and low operation efficiency.

[0006] In view of the problems in the related art, no effective solution has been proposed yet.

[0007] Therefore, in order to solve the above problems, the utility model provides a pre-screening device on a mushroom screening machine. Content of the Utility Model

The cleaning mechanism can clean the screen in the vibrating screen, and the lifting mechanism can lift and transport the conveying box, so as to facilitate the transportation of mushrooms. This method is simple to operate, can reduce the labor intensity of the workers, and thus ensure the screening efficiency of mushrooms.

[0009] The purpose of the utility model can be realized by the following technical solutions:

[0010] A pre-screening device on a shiitake mushroom screening machine, comprising a base, a vibrating screen is installed at the top of the base, a cleaning mechanism is arranged at the top of the vibrating screen, the cleaning mechanism includes an electric guide rail and an electric push rod, a plurality of cleaning rods are arranged at the bottom end of the electric push rod, a conveying box is arranged on one side of the vibrating screen, and a lifting mechanism for conveying the conveying box is also installed at the top of the base.

When the conveying box rises above the vibrating screen, first pull out the draw plate from the bottom plate, and then bend the bottom plate downward to separate the magnets that adsorb the bottom plate and the conveying box. The bottom plate can automatically rotate downward under the action of gravity until it hits the limit frame. At this time, the bottom plate is inclined, and the shiitake mushrooms in the conveying box can flow into the vibrating screen along the bottom plate for screening operations. When some mesh holes on the first screen or the second screen are blocked by shiitake mushrooms, the cleaning rod is moved to directly above the mesh hole through the action of the electric guide rail, and then the cleaning rod is driven to descend by the electric push rod, so that the electric push rod can squeeze the shiitake mushrooms stuck in the mesh hole to make them flow out. This method is simple to operate, can reduce the labor intensity of the staff, and thus ensure the screening efficiency of shiitake mushrooms. BRIEF DESCRIPTION OF THE DRAWINGS
