Abstract

The utility model relates to a tea screening machine with a vibration-absorber. The utility model comprising a machine case and a screening device which are arranged on a platform base, and the interior of the machine case is also provided with the vibration-absorber which is composed of a main girder arranged in the machine case and a matching block placed in a frame. The frame of the upper side of the matching block is provided with two parallel cross girders, and each cross girder is provided with a shaft lever which is connected in series with a pushing eccentric wheel and two diversionary eccentric wheels. When the pushing eccentric wheel pushes the screening device to make reciprocating motion, the diversionary eccentric wheels can provide an opposite torque to counteract the inertia. Thus, the vibration of the screening machine can be reduced to the minimum, and besides, the installation and the removal of the screening machine is more convenient than that of the original screening machine.

Description

Tea screening machine with vibration-absorber

The utility model relates to the reciprocating screen screening device, is meant a kind of Tea screening machine with damping device particularly.

Regular meeting uses a kind of Tea screening machine in the tea baking manufacture craft; it is made up of discrete screening plant and cabinet; screening plant is to have one several layer of screening frame; its four limit is to be articulated in a support; support bottom nailing is fixed in ground; motor and percussion mechanism are arranged in the cabinet; cabinet is positioned at the screening plant rear; reciprocal shake moved before and after the screening frame drove the screening frame by percussion mechanism in the cabinet at rear; and wait that the tealeaves that screens falls in the screening filter screen of the superiors; when shake moves, make separation successively such as broken end, the branch of tealeaves obstruct according to width of mesh.

This kind commonly used structure and produced huge vibrations because of meeting, so screening plant and cabinet must be fixed in ground, still can be offset by occurrence positions even so, the vibrations noise is big, the phenomenon of machine rapid wear, often must remove when the producer desires to readjust in the factory building board position besides with making a great fuss, move, work such as nailing, very inconvenient.

The purpose of this utility model provides a kind of Tea screening machine with damping device, it screening plant and cabinet are set as one and shake little, resettlement, install very convenient.

To achieve these goals, the technical solution adopted in the utility model is: with to commonly use Tea screening machine the same, also include screening plant and cabinet, screening plant is a side column around being, screening rack and screen, funnel constitutes, motor is arranged in the cabinet, percussion mechanism is arranged, motor and percussion mechanism make screening plant do back and forth to shake to move in the cabinet, institute's cabinet that is not both and screening plant are fixedly arranged on the identical platform base, cabinet and platform base form a L type, also be equiped with a damping device in the cabinet, it is to set firmly the framework of a band girder and form the space that can place balancing weight in cabinet, on the framework above the balancing weight, be provided with two crossbeams arranged side by side, which is provided with an axostylus axostyle, the axostylus axostyle two ends are serially connected with an idle pulley and belt pulley respectively, belt pulley is by set motor and the belt transmission of cabinet inner bottom part, and the part centre position of the axostylus axostyle between two crossbeams serial connection one is carried out eccentric wheel, the eccentric wheel two ends respectively are provided with one again and hold up eccentric wheel, and implementation eccentric wheel front end extends one and can pass the front rod that cabinet promotes the reciprocal vibrations of screening plant, and two hold up eccentric wheel respectively to extend a back link that links to each other with girder.After motor drives the belt pulley rotation, when the implementation eccentric wheel is back and forth carried out screening plant with front rod, owing to be subjected to holding up eccentric wheel to hold up, and offset the inertia strength of carrying out eccentric wheel, the vibrations that make the box body running be produced reduce to minimum.

Because the utility model has been set up damping device, make screening machine shake the flimsy phenomenon that reduces and avoided displacement and machine, because screening plant and cabinet are installed on the identical platform base, make that the installation of screening machine and resettlement are all very convenient.

Below in conjunction with an accompanying drawing and a typical embodiment the utility model is done a detailed description:

The Tea screening machine structural representation is commonly used by Fig. 1 system.

Fig. 2 is the schematic perspective view of the utility model.

Fig. 3 is the utility model cabinet internal damping apparatus structure schematic diagram.

Fig. 4 is the utility model cabinet internal damping device action schematic diagram.

The Tea screening machine that has damping device as shown in Figure 2 is to comprise vertical chassis 21, its top is provided with loading hopper 22, cabinet 21 left sides are provided with a screening plant 3, it is fixing that four side columns 31 in the screening plant 3 will screen rack 32, screen pack 34 places rack 32, funnel 33 is arranged at screening rack 32 left sides, and cabinet 21 is positioned on the platform base 2 with screening plant 3, and cabinet 21 forms a L type pedestal with platform base 2.

In order to reach the vibrating effect when eliminating machine run, in the damping device installing cabinet 21, be to be fixedly arranged in the case 21 and to form an accommodation space with several girders, its space is placed with the balancing weight 24 of proper number, on the framework above the balancing weight 24, be provided with two crossbeams 23 arranged side by side, end face has set up an axostylus axostyle 4 on it, its two ends are serially connected with an idle pulley 41 and belt pulley 42 respectively, belt pulley 42 be with motor set at the bottom of the case with the belt interlock, and carry out eccentric wheel 43 in the centre position serial connection one of the part of the axostylus axostyle 4 of 23 on two crossbeams, its both sides then respectively are connected in series one again and hold up eccentric wheel 44, carrying out eccentric wheel 43 front ends is to receive a front rod 431, it is to pass the cabinet preformed hole to be connected in screening plant 3 rear ends, holds up eccentric wheel 44 rear ends then respectively to extend a back link 441, and its end all is connected in the case middle girder.When operation is tea raw material to be stacked in the loading hopper 22, and flow to screening plant 3 the superiors' filter screens by the outlet of loading hopper 22 front ends, axostylus axostyle 4 in the cabinet 21 is with belt transmission by motor at this moment, because of carrying out eccentric wheel 43 and holding up eccentric wheel 44, it is eccentric structure and can produce reciprocating, see also Fig. 4, when carrying out seeing through 3 reciprocating motions of front rod 431 promotion sorting mechanisms when eccentric wheel 43 moves ahead, holding up 44 of eccentric wheels to see through back link 441 respectively holds up in girder and framework, utilize the principle that otherwise two directions phase moment can be cancelled out each other on the mechanics, and eliminated the inertia strength of carrying out eccentric wheel 43, it is minimum that the vibrations that make box body be produced because of running reduce to, and improves the drawback of commonly using Tea screening machine effectively.

By above structure introduction as can be seen because the screening plant 3 and the cabinet 21 of the utility model all be arranged on the platform base 2, so its in factory building, install or needn't be fixed in ground in modes such as nailings fully when carrying screening machine, thereby improved efficient.
