Abstract

The utility model relates to a dry tea grader pressing device, which comprises a pressing handle, wherein the pressing handle is arranged on the dry tea grader through a bolt, the pressing end of the pressing handle is provided with an arc-shaped pressing protrusion, the pressing handle is pressed, the arc-shaped pressing protrusion presses a screen on the dry tea grader to enable the screen to be overlapped and pressed without loosening, and a movable pressing cushion block is arranged below the pressing handle; the upper surface of the pressing cushion block is a trapezoidal inclined surface with one side higher and the other side lower. This closing device does not change the body structure of original dry tea grader, through the cushion that compresses tightly that increases the activity, the cushion that compresses tightly of activity is the trapezoidal inclined plane of height on one side low, can be according to the different characteristics of screen cloth height difference, the back-and-forth movement compresses tightly the cushion, press fixed compressing handle, fix the screen cloth, simultaneously, the lower surface that will compress tightly the cushion designs into with screen cloth frame recess assorted projection, make and compress tightly the cushion and facilitate the installation in the recess, make it vibrate the difficult off tracking of in-process at the screen cloth.

Description

Pressing device of dry tea classifier

Technical Field

The utility model relates to a tea production equipment, in particular to a closing device for on dry tea grader.

Background

Last process in tea production just grades finished product tealeaves according to the size of blade and packs after, current tea grader adopts the screen cloth of mesh size difference mostly, adopt the mode of vibration, sift out the tealeaves of equidimension not layer by layer, the compression handle in the tea grader, through pressing the compression handle, its arc compresses tightly protruding last screen cloth of pressing dry tea grader, make the unsmooth stack of screen cloth on the dry tea grader compress tightly not hard up, but in process of production, because the tealeaves of sifting different can use different screen cloths, closing device before is fixed unmovable, therefore, the not hard up phenomenon of screen cloth can take place often in the production process, influence the branch sieve effect of tealeaves.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the not hard up unfavorable phenomenon of bringing of screen cloth, provide a dry tea grader closing device, the device is under the condition that does not change the major structure of tealeaves grader, and the convenience is consolidated the screen cloth.

Compared with the prior art, the beneficial effects of the utility model are that: a pressing device of a dry tea classifier comprises a pressing handle, the pressing handle is installed on the dry tea classifier through bolts, an arc-shaped pressing protrusion is arranged at the pressing end of the pressing handle, the pressing handle is pressed, the arc-shaped pressing protrusion presses a screen on the dry tea classifier, the screen is overlapped and pressed in a concave-convex mode and is not loosened, and a movable pressing cushion block is padded below the pressing handle; the upper surface of the pressing cushion block is a trapezoidal inclined plane with one higher side and one lower side.

Furthermore, the lower surface of the pressing cushion block is provided with a convex column matched with the groove of the screen frame.

Further, the compression cushion block is made of wood or hard metal.

The utility model has the advantages that: this closing device is under the condition that does not change original dry tea grader's body structure, through increasing the movable cushion that compresses tightly, the movable cushion that compresses tightly is the trapezoidal inclined plane that high one side is low, can be according to the different characteristics of screen cloth height difference, the back-and-forth movement compresses tightly the cushion, press fixed compressing handle afterwards, fix the screen cloth, and simultaneously, the lower surface that will compress tightly the cushion designs into with screen cloth frame recess assorted projection, make and compress tightly the cushion and conveniently install in the recess, make it vibrate the difficult off tracking of in-process at the screen cloth.
