Abstract

The embodiment of the utility model discloses a screen plate mechanism of a coal breaking sampler, which comprises a crushing cavity, a screen plate, a frame, a connecting rod, a vibrating shaft and a connecting device on a vibrating shaft sleeve. The connecting rod is in rotational connection with the frame and the screen plate respectively; the connecting device on the vibrating shaft sleeve is connected with the screen plate; and when the vibrating shaft rotates, the screen plate vibrates correspondingly. In the embodiment of the utility model, the screen plate is arranged in movable connection, so that the screen plate can vibrate during machine operation. During the vibration of the screen plate, the bonded material can be shaken off, thereby solving the bonding and blockage problem of the material in the crushing cavity.

Description

A kind of sieve plate mechanism of coal crushing sampling machine

Technical field

The utility model relates to coal sample preparation disintegrating machine technical field, more particularly, relates to a kind of sieve plate mechanism of coal crushing sampling machine.

Background technology

Along with the demand of people to resource, coal industry is greatly developed, and the Coal Mechanical of bringing thus also develops very fast, and coal sample preparation disintegrating machine is playing an important role aspect the coal crushing sampling experiment as a kind of of Coal Mechanical.

Coal sample preparation disintegrating machine is mainly used in the broken link in the commercial coal sample preparation, can also comprise the fragmentation of some unclassified stores, as ore, and slag etc.After the coal charge fragmentation, through the screening of sieve plate mechanism, obtains thinner coal charge, shown in Fig. 1 is existing sieve plate mechanism, and wherein 1 be sieve plate, and 2 be crusher chamber, and 3 is hopper, and the screening of the coal charge process sieve plate that fragmentation finishes in crusher chamber enters hopper.Because sieve plate is actionless, relatively moister material can be bonded on the sieve plate hole, and it is sticking stifled to cause material to produce in crusher chamber.

The utility model content

In view of this, the purpose of this utility model is to provide a kind of sieve plate mechanism of coal crushing sampling machine, to improve the sticking stifled problem of crusher chamber.

The utility model embodiment is achieved in that

A kind of sieve plate mechanism of coal crushing sampling machine, comprise the coupling arrangement on crusher chamber, sieve plate, frame, connecting rod, vibrating shaft and the vibrating shaft axle sleeve, described connecting rod is rotationally connected with described frame and described sieve plate respectively, coupling arrangement on the described vibrating shaft axle sleeve is connected with described sieve plate, when described vibrating shaft rotates, make described sieve plate and then vibrate.

Preferred above-mentioned sieve plate mechanism, described vibrating shaft is excentric shaft or the axle that is provided with decentralizing device.

Preferred above-mentioned sieve plate mechanism, described being rotationally connected is that hinge connects.

Preferred above-mentioned sieve plate mechanism, the coupling arrangement on the described vibrating shaft axle sleeve is connected with described sieve plate by bolt.

By technique scheme as can be known, compared with prior art, the utility model embodiment is by being arranged to sieve plate to be dynamically connected, make that sieve plate can vibrate when machine run, in vibration processes, the material of bonding can be shaken off, make equipment can adapt to the fragmentation that contains the higher material of moisture, can solve material in the sticking stifled problem of crusher chamber.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is existing sieve plate mechanism structure figure;

The sieve plate mechanism structure figure of a kind of coal crushing sampling machine that Fig. 2 provides for the utility model embodiment;

Fig. 3 is the left view of Fig. 2.

Embodiment

Material after the fragmentation flows down from discharging opening by the hole on the sieve plate, owing to contain moisture, material can be bonded on the sieve plate hole, and it is sticking stifled to cause material to produce in crusher chamber, and the sieve plate in the existing sieve-plate structure is actionless, can't solve the sticking stifled problem of crusher chamber.

The utility model embodiment provide a solution, and its basic thought is: sieve plate is arranged to be dynamically connected, and sieve plate can vibrate when machine run, improve the sticking stifled problem of crusher chamber greatly.

Understand the technical solution of the utility model for those skilled in the art can be known, the technical solution of the utility model is described in detail below in conjunction with drawings and Examples.

See also Fig. 2, the sieve plate mechanism structure figure of a kind of coal crushing sampling machine that Fig. 3, Fig. 2 provide for the utility model embodiment, Fig. 3 is the left view of Fig. 2.

Wherein 1 is sieve plate, and 2 is crusher chamber, and 4 is belt wheel, and 5 is vibrating shaft, and 6 is the coupling arrangement on the vibrating shaft axle sleeve, and 7 is frame, and 8 is connecting rod.

Crusher chamber 2 is the material container cavity, and material can enter crusher chamber 2 from a last operation, the screening of being undertaken material by sieve plate 1.

The two ends of connecting rod 8 are rotationally connected with frame 7 and sieve plate 1 respectively, (described being rotationally connected promptly can guarantee interconnective two rotary connections of parts, as hinge connection etc.), coupling arrangement 6 on the vibrating shaft axle sleeve is connected with sieve plate 1 by bolt etc., vibrating shaft 5 is provided with decentralizing device for excentric shaft or its, belt wheel 4 is given vibrating shaft 5 with transmission of power, because vibrating shaft 5 is provided with decentralizing device for excentric shaft or its, make when vibrating shaft 5 rotates, judder can take place, the vibration meeting passes to sieve plate 1 by the coupling arrangement on the vibrating shaft axle sleeve 6, because the two ends of connecting rod 8 are for being rotationally connected, connecting rod 8, sieve plate 1 and coupling arrangement 6 have been formed a simple toggle, when vibrating shaft rotates, make sieve plate 1 and then vibrate.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
